SYNOPSIS 
Protocol Title: A Phase IIIb, Randomized, Multicenter, Parallel-group, Non-inferiority, 
Open-label Study Evaluating the Efficacy, Safety, and Tolerability of Long-acting 
Cabotegravir Plus Long-acting Rilpivirine Administered Every 8 Weeks or Every 4 
Weeks in HIV-1-infected Adults who are Virologically Suppressed. 
Short Title: Study Evaluating the Efficacy, Safety, and Tolerability of Long-acting 
Cabotegravir Plus Long-acting Rilpivirine administered every 8 weeks in Virologically 
Suppressed HIV-1-infected Adults. 
1.1. 
Rationale 
The 207966 (ATLAS-2M) study is being conducted to establish if human 
immunodeficiency virus type 1 (HIV-1) infected adult participants with current viral 
suppression (HIV-1 RNA 50 c/mL) remain suppressed upon administration of a two-
drug intramuscular (IM) long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine 
(RPV) administered every 8 weeks (Q8W; every 2 months).  This study is designed to 
demonstrate the non-inferior antiviral activity of CAB LA 600 mg + RPV LA 900 mg 
administered every 8 weeks compared with CAB LA 400 mg + RPV LA 600 mg 
administered every 4 weeks (Q4W; monthly) over a 48-week treatment period.  ATLAS-
2M will also provide comparative data on antiviral activity, safety, tolerability, and 
patient satisfaction through Week 152.   
Two groups of participants with demonstrated virologic suppression will be enrolled into 
ATLAS-2M including participants who at Screening are 1) receiving oral standard of 
care triple antiretroviral therapy (SOC) or 2) receiving a two drug IM regimen of Q4W 
CAB LA + RPV LA.  The majority of participants in ATLAS-2M will rollover from the 
ongoing 201585 (ATLAS) trial and additional participants on SOC will also be included 
in order to support a targeted total sample size of approximately 1020 participants.  
Participants entering on SOC treatment consisting of a stable antiretroviral (ARV) 
regimen containing 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an 
integrase inhibitor (INI), non-nucleoside reverse transcriptase inhibitor (NNRTI), or a 
protease inhibitor (PI), will therefore either enter as new study participants or will 
rollover from the ongoing ATLAS trial.  All participants entering on Q4W CAB LA + 
RPV LA will be rolled over from the ATLAS trial.     
ATLAS is a Phase III, randomized, multicenter, parallel-group, non-inferiority, open-
label study evaluating the efficacy, safety, and tolerability of switching to CAB LA + 
RPV LA from current INI- NNRTI-, or PI-based antiretroviral regimen in HIV-1-infected 
adults who are virologically suppressed.  ATLAS participants randomized to the SOC, 
“current antiretroviral” treatment arm, consisting of 2 nucleoside reverse transcriptase 
inhibitors (NRTIs) plus a third agent (INI, NNRTI, or a PI), or the CAB LA + RPV LA 
Q4W arm, who successfully complete Week 52 (at minimum) of ATLAS, and remain 
virologically suppressed (HIV-1 RNA <50 c/mL), will be eligible to enter ATLAS-2M.    
Eligible participants entering ATLAS-2M on oral SOC (either from ATLAS or new 
participants) will be randomized (1:1) to the CAB LA + RPV LA Q4W or Q8W regimen 

TMF-13901227

beginning with 4 weeks of oral lead-in with CAB + RPV to confirm tolerability prior to 
IM dosing with CAB LA and RPV LA.  Eligible participants entering from ATLAS on 
the CAB LA+ RPV LA Q4W regimen will be randomized (1:1) to either continue Q4W 
injections or transition to Q8W injections in ATLAS-2M (without the oral lead-in).  
All participants who successfully complete Week 100 of CAB LA + RPV LA treatment 
in the Maintenance Phase will continue to have access to their randomized CAB LA + 
RPV LA regimen in the Extension Phase through Week 152 and until CAB LA and RPV 
LA are either locally approved and commercially available, the participant no longer 
derives clinical benefit, the participant meets a protocol-defined reason for 
discontinuation or until development of their assigned CAB LA + RPV LA regimen is 
terminated.

Overall Design 
Study 207966 (Antiretroviral Therapy as Long Acting Suppression every 2 Months-
ATLAS-2M) is a Phase III, randomized, open-label, active-controlled, multicenter, 
parallel-group, non-inferiority study designed to assess the antiviral activity and safety of 
CAB LA + RPV LA administered every 4 weeks compared to CAB LA + RPV LA 
administered every 8 weeks in approximately 1020 adult HIV-1 infected participants.   
Two groups of patients who fulfill eligibility requirements will be randomized (1:1) to 
receive CAB LA + RPV LA Q4W, or CAB LA + RPV LA Q8W regimen for at least 100 
weeks:  
Group 1: Patients randomized from current ART SOC therapy 
Patients randomized from current ART SOC therapy, including those enrolled to the 
“current ART” arm of the ATLAS study following completion of the Week 52 visit (at 
minimum), will begin oral therapy with CAB 30 mg + RPV 25 mg once daily at Day 1 
for 28 days (3 days) to determine individual safety and tolerability prior to receiving 
CAB LA + RPV LA Q4W, or CAB LA + RPV LA Q8W.  For patients on SOC 
transitioning from the ATLAS trial, eligibility for ATLAS-2M can be determined once

the final central lab results from ATLAS are available and safety parameters have been 
reviewed. 
Group 2: Patients currently receiving CAB LA + RPV LA Q4W 
Patients currently receiving CAB LA + RPV LA Q4W within ATLAS will be 
randomized at Day 1 to either continue Q4W administration or transition to Q8W 
administration of CAB LA + RPV LA.  Eligible patients include those originally 
randomized to Q4W in the Maintenance phase of ATLAS and those who transitioned 
from SOC to the Q4W regimen within the Extension Phase of ATLAS.  The first 
injection visit for ATLAS-2M can be performed once the final central lab results from 
ATLAS are available and safety parameters have been reviewed, and the ATLAS 
Week 52 visit (at minimum) has been completed.  Participants will continue to receive 
CAB LA + RPV LA Q4W injections as scheduled within the ATLAS trial until their 
eligibility for ATLAS-2M can be fully evaluated and the participant is re-randomized 
(Q4W or Q8W).  If determined to be ineligible for ATLAS-2M, those participants can 
elect to continue participation in ATLAS or withdraw from the ATLAS study. 
Participants in ATLAS-2M who successfully complete Week 100 (without meeting study 
defined withdrawal criteria) will be given the option to continue to receive their 
randomized treatment (CAB LA + RPV LA administered Q4W or Q8W) in the Extension 
Phase through Week 152 and until the study treatment is either locally approved and 
commercially available within the local sector (including through local 
public/government health sectors), the participant no longer derives clinical benefit, the 
participant meets a protocol-defined reason for discontinuation or until development of 
either CAB LA + RPV LA Q4W and/or Q8W is terminated.  Alternatively, participants 
can choose to complete study participation and enter the 52-week Long-Term Follow-Up 
(LTFU) Phase of the study. 
Any participant who receives at least one dose of CAB LA and/or RPV LA and 
discontinues the CAB LA + RPV LA regimen for any reason will enter a 52-week LTFU 
Phase (please refer to Section 1.4.4 of the synopsis for additional details).  Those 
participants must remain on suppressive highly active antiretroviral therapy (HAART) for 
at least 52 weeks after the last dose of CAB LA and/or RPV LA. 
In order to achieve balance across the treatment arms, randomization will be stratified by 
prior CAB + RPV Exposure: 0 weeks, 1-24 weeks, >24 weeks.  The primary endpoint for 
the study is the proportion of participants with HIV-RNA greater than or equal to 
50 c/mL (Virologic Failure) at Week 48 as per Food and Drug Administration (FDA) 
Snapshot algorithm using the Intent-to-Treat Exposed (ITT-E) population.  The 
proportion of participants with plasma HIV-1 RNA <50 c/mL at Week 48 using the FDA 
Snapshot algorithm (Missing, Switch or Discontinuation = Failure, ITT-E population) is a 
key secondary endpoint comparison.   
The sample size of 1020 provides 85% power to demonstrate non-inferiority in the 
primary endpoint at Week 48 using a 4% margin, assuming a true 3% failure rate for 
Q8W CAB LA + RPV LA and a 2% failure rate for the Q4W CAB LA + RPV LA arm 
and a 2.5% one-sided alpha level (using unpooled Z test statistic).

Number of Participants 
The target population to be enrolled is HIV-1 infected virologically suppressed (HIV-1 
RNA <50 c/mL) patients on stable antiretroviral therapy (ART) including participants 
who have completed, at minimum, Week 52 of the ATLAS study. 
It is anticipated that approximately 1020 participants will be enrolled into ATLAS-2M.  
In addition to participants rolled over from the ATLAS study, additional participants on 
SOC treatment will be screened to supplement enrollment such that the study can be 
appropriately powered.  A 15% screen failure rate, for additional patients randomized 
from SOC treatment is anticipated.  Participants will be enrolled from multiple countries 
which may include those countries actively participating in the ATLAS study including 
Australia, Argentina, Canada, France, Germany, Italy, Mexico, Russia, South Africa, 
South Korea, Spain, Sweden, and the United States.  
Randomization will be stratified by prior CAB + RPV exposure: 0 weeks, 1-24 weeks, 
>24 weeks.  A goal of this study is to enroll populations who are underrepresented in 

TMF-13901227

207966 
22 
 
clinical studies including approximately 25% women.  To provide sufficient data to 
determine whether either gender is correlated with treatment response, sites are expected 
to take into account gender in their screening strategies.  
1.4. 
Treatment Groups and Duration 
1.4.1. 
Screening Phase (Up to 35 days) 
Informed consent must be obtained prior to any study procedures, including any 
Screening assessment. 
Participants will be involved in a Screening period of up to 35 days and may be re-
screened once.  Participants who are randomized into the trial and subsequently 
withdrawn from the study, for any reason, may not be re-screened.  Participants may be 
randomized as soon as all eligibility requirements have been confirmed at the site. 
For participants transitioning from the ATLAS study, eligibility to transition to ATLAS-
2M at Week 52 (at the earliest) will be determined once the final central lab results from 
ATLAS, following (at minimum) completion of the ATLAS Week 48 visit are available 
and safety parameters have been reviewed.  Separate Screening Labs will be utilized to 
inform eligibility for ATLAS-2M; however, in some occasions and upon consultation 
with the Medical Monitor, individual lab results and safety data from the final visit of the 
ATLAS study can be considered towards informing eligibility for the ATLAS-2M study 
as long as all other Screening and eligibility criteria are met.     
1.4.2. 
Maintenance Phase (Day 1 up to Week 100) 
There are two ways in which study participants may transition to the LA regimen, either 
directly from oral SOC or from Q4W dosing from ATLAS.  
The Table and Figure below describe the CAB LA + RPV LA dosing regimens in 
ATLAS-2M based on the mode of transition.

1.4.2.1. 
Patients randomized to LA dosing from current ART SOC therapy: 
All participants randomized from current ART SOC therapy (including those 
transitioning from SOC in ATLAS and new study participants) will begin oral therapy 
with CAB 30 mg + RPV 25 mg once daily at Day 1 for 4 weeks to determine individual 
safety and tolerability prior to administration of CAB LA + RPV LA.  The oral lead-in 
period is part of the Maintenance Phase and will therefore be included within the Week 
48, 96, and 152 planned analyses.  
The final dosing of current daily oral ART regimen should occur the day prior to 
randomization to avoid overlap of treatment regimens however, if the participant takes

current ART prior to coming into the clinic, randomization and initiation of oral CAB 
and RPV should continue as planned for Day 1.  At the Week 4a visit, safety assessments 
(including e.g., clinical chemistries) will be performed as per the Time and Events Table 
to determine individual safety and tolerability prior to the initial administration of CAB 
LA + RPV LA.  Dosing of CAB LA + RPV LA Q4W or Q8W will initiate at the Week 
4b visit once safety labs from Week 4a are available and have been reviewed. 
Subjects receiving oral SOC treatment and randomized to Q4W injections will receive 
loading doses of CAB LA 600 mg + RPV LA 900 mg on Week 4b followed by 
maintenance injections of CAB LA 400 mg + RPV LA 600 mg every 4 weeks thereafter.   
Subjects receiving oral SOC treatment and randomized to Q8W injections will receive 
doses of CAB LA 600 mg + RPV LA 900 mg on Week 4b and Week 8 followed by 
identical maintenance dose injections every 8 weeks thereafter. 
All injections should be planned as single injections per drug. 
1.4.2.1.1. IM injections every 4 weeks (Q4W from SOC): 
Week 4b visit only - CAB LA 600 mg + RPV LA 900 mg, each given as 1 X 3 mL IM 
injection 
Week 8 visit and Q4W thereafter - CAB LA 400 mg IM + RPV LA 600 mg IM every 4 
weeks for 100 weeks, each given as 1 X 2 mL IM injection 
At Week 4b, participants will return to the clinic, take the last oral dose (CAB 30 mg + 
RPV 25 mg), and receive the first CAB LA (600 mg) + RPV LA (900 mg) injections 
(within 2 hours of the final oral dose of CAB + RPV).  The first injection visit with IM 
CAB LA + RPV LA at Week 4b can be performed once central lab results are available 
and safety parameters are reviewed from the Week 4a visit.   
The second and third IM injections with CAB LA 400 mg and RPV LA 600 mg will be 
performed at Week 8 and Week 12.  There will be a -7-day dosing window for the second 
and third IM injections such that the second injection occurs within the window of Week 
7 and Week 8 but no later than Week 8 and the third injection occurs within the window 
of Week 11 and Week 12 but no later than Week 12.  Subsequent injections with CAB 
LA 400 mg and RPV LA 600 mg will occur every 4 weeks (7 days) thereafter.  In 
addition, starting after the Week 16 injection, the interval between injection visits will be 
limited to a maximum of 5 weeks.  The Medical Monitor must be contacted to discuss 
individual participant case management if the length of time between injections exceeds 
or is projected to exceed 5 weeks. 
1.4.2.1.2. IM injections every 8 weeks (Q8W from SOC): 
Week 4b visit – CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM 
injection 
Week 8 visit- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM 
injection

Week 16 visit and Q8W thereafter - CAB LA 600 mg + RPV LA 900 mg IM, every 8 
weeks for 100 weeks, each given as 1 X 3 mL IM injection 
At the Week 4b visit, subjects will return to the clinic, take their last oral dose (CAB 
30 mg + RPV 25 mg), and receive the first CAB LA (600 mg) + RPV LA (900 mg) 
injections (within 2 hours of the final oral dose of CAB + RPV).  The first injection visit 
with IM CAB LA + RPV LA at Week 4b can be performed once central lab results are 
available and safety parameters are reviewed from the Week 4a visit.   
The second loading injection will be administered at Week 8 (CAB LA 600 mg + RPV 
LA 900 mg), with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring 
every 8 weeks thereafter.  There will be a -7-day dosing window for the second and third 
IM injections such that the second injection occurs within the window of Week 7 and 
Week 8 but no later than Week 8 and third injection occurs within the window of Week 
15 and Week 16 but no later than Week 16.  Subsequent injections with CAB LA 600 mg 
and RPV LA 900 mg will occur every 8 weeks (7 days).  Starting after the Week 16 
injection, the interval between injection visits will be limited to a maximum of 9 weeks.  
If the length of time between injections exceeds, or is projected to exceed 9 weeks, the 
Medical Monitor must be contacted to discuss individual participant case management.   
1.4.2.2. 
Participants transitioning from ATLAS and currently receiving CAB LA 
+ RPV LA Q4W 
Subjects receiving Q4W injections within ATLAS and randomized to receive Q4W 
injections in ATLAS-2M, will continue receiving maintenance injections Q4W as 
scheduled and will not require a loading dose on Day 1. 
Subjects receiving Q4W injections within ATLAS and randomized to receive Q8W 
injections in ATLAS-2M will receive doses of CAB LA 600 mg + RPV LA 900 mg on 
Day 1 one month after their last Q4W maintenance dose in order to align with day of 
study randomization.  Subjects will not require an intermediate dose at Week 4 and will 
receive their next Q8W maintenance injections at Week 8 and Q8W thereafter.   
Participants transitioning from the ATLAS study and on CAB LA + RPV LA Q4W 
treatment will be randomized at Day 1 to either continue Q4W administration or 
transition to Q8W administration of CAB LA + RPV LA.  The first injection visit for the 
ATLAS-2M study can be performed once the final central lab results from the ATLAS 
study are available and safety parameters have been reviewed.  Screening labs 
determining eligibility for ATLAS-2M can be collected at Week 48 (at minimum) for 
participants originally randomized to the Q4W arm within ATLAS.  Screening labs for 
participants who recently transitioned from SOC to Q4W injections within the ATLAS 
Extension Phase may be obtained at ATLAS Week 56b (after completion of the CAB + 
RPV Oral lead-in period) or at a subsequent ATLAS visit after receiving one set or a 
short course of Q4W injections.  The transition from the final ATLAS to ATLAS-2M 
Day 1 dosing must occur 4 weeks (7 days) from the final injections received in ATLAS.  
Dosing for participants transitioning from CAB LA + RPV LA Q4W in ATLAS is as 
follows: 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
26 
 
1.4.2.2.1. IM injections every 4 weeks (Q4W from ATLAS Q4W): 
Starting at Day 1, all injections will continue with the maintenance dose of CAB LA   
400 mg and RPV LA 600 mg administered every 4 weeks (7 days).  In addition, the 
time between injection visits will be limited to a maximum of 5 weeks.  The Medical 
Monitor must be contacted if the length of time between injections exceeds or is 
projected to exceed 5 weeks. 
1.4.2.2.2. IM injections every 8 weeks (Q8W from ATLAS Q4W): 
Participants transitioning from ATLAS and randomized to receive CAB LA + RPV LA 
Q8W injections will initiate Q8W dosing at the Day 1 visit as follows:  
Day 1- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM injection 
Week 8 and Q8W thereafter- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 
3 mL IM injection 
The second injection will be administered at Week 8 (CAB LA 600 mg + RPV LA 
900 mg, with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring 
every 8 weeks thereafter.  There will be a -7-day dosing window for the second and third 
IM injections such that the second injection occurs within the window of Week 7 and 
Week 8 but no later than Week 8 and third injection occurs within the window of Week 
15 and Week 16 but no later than Week 16.  Subsequent injections with CAB LA 600 mg 
and RPV LA 900 mg will occur every 8 weeks (7 days).  Starting after the Week 16 
injection, the interval between injection visits will be limited to a maximum of 9 weeks.  
If the length of time between injections exceeds, or is projected to exceed 9 weeks, the 
Medical Monitor must be contacted to discuss individual participant case management.   
The primary study analysis will consist of data collected through the Week 48 visit.  A 
single repeat of HIV-1 RNA for any participant with a HIV-1 RNA 50 c/mL at Week 
48, Week 96, or Week 152 must be performed.  The retest should be scheduled as soon as 
possible (but no later than 4 weeks from the Week 48, Week 96, or Week 152 visits, 
respectively) and will inform the Week 48,Week 96, or Week 152 virological endpoint, 
respectively.   
1.4.3. 
Extension Phase 
Participants who successfully complete 96 Weeks of CAB LA + RPV LA treatment in 
the Maintenance Phase will continue to have access to their randomized treatment Q4W 
or Q8W CAB LA + RPV LA in the Extension Phase through Week 152 and until study 
treatment is either locally approved and commercially available within the local sector 
(including through local public/government health sectors), the participant no longer 
derives clinical benefit, the participant meets a protocol-defined reason for 
discontinuation or until development of either CAB LA + RPV LA Q4W and/or Q8W is 
terminated.  For participants randomized to Q4W arm, dosing visits will continue to 
occur every 4 weeks with CAB LA 400mg and RPV LA 600 mg.  For participants 
randomized to the Q8W arm, dosing visits will continue to occur every 8 weeks with 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
27 
 
CAB LA 600 mg and RPV LA 900 mg.  Safety and efficacy assessments will be 
conducted as per the Time and Events Schedule.  
Participants choosing to not enter the Extension phase can complete their study 
participation at the Week 100 visit and enter into the LTFU Phase as required.  
Participants who choose to continue on to the Extension Phase will need to be assessed 
for eligibility and will continue on their current CAB LA + RPV LA regimen while 
eligibility is being confirmed.  A single repeat of HIV-1 RNA for any participant with a 
HIV-1 RNA 50 c/mL and < 400 c/mL at Week 96 or Week 152 must be performed.  
The retest should be scheduled as soon as possible (but no later than 4 weeks from the 
Week 96 or Week 152 visit).  Participants with HIV-1 RNA <50 c/mL upon retest are 
eligible to enter the Extension Phase.  Participants with HIV-1 RNA ≥400 c/mL at 
Week 96 are not eligible to enter the Extension Phase, will not be allowed a repeat to 
determine eligibility, and will therefore be withdrawn from the study treatment.  
Eligibility to enter the Extension Phase for any participants with a retest HIV-1 RNA > 
50 c/mL and <400 c/mL will require approval by the study Medical Monitor.   
Participants not eligible to enter the Extension Phase or choosing not to participate in the 
Extension Phase will end their study treatment and enter the LTFU Phase. Sites may be 
reimbursed for up to a one-month supply of antiretroviral medication to facilitate 
transition to non-study ART for participants that do not qualify for the Extension Phase. 
1.4.4. 
Long-Term Follow-Up Phase 
• 
Any participant who receives at least one dose of CAB LA and/or RPV LA and 
discontinues the CAB LA + RPV LA regimen for any reason before CAB LA + 
RPV LA marketed product is locally available must enter the LTFU Phase.   
Participants must remain on suppressive HAART for at least 52 weeks after the 
last dose of CAB LA and/or RPV LA in order to prevent selective pressure on 
HIV and the potential for selection of resistant mutants.  Investigators must 
discuss the choice of the follow-up HAART regimen with the Medical 
Monitor prior to initiating the new regimen with the participant.  HAART 
therapy should be initiated within 4 weeks (+7 days) after the last Q4W 
injection, or within 8 weeks (+7 days) after the last Q8W injection.  The 
LTFU Phase will begin the day of the last CAB LA and/or RPV LA dose and 
continue for 52 weeks..  Upon discontinuation from the Maintenance or 
Extension Phase, these participants will complete Withdrawal assessments  (see 
Section 5.5) and will then enter into the LTFU Phase as per the Time and Events 
Schedule (Section 7.1).   
 
• Where the CAB LA + RPV LA marketed product is locally available, only 
participants that discontinue the CAB LA + RPV LA regimen for safety-related 
reasons included in Section 5.5, must enter the LTFU Phase. Participants must 
remain on suppressive HAART for at least 52 weeks after the last dose of CAB 
LA and/or RPV LA in order to prevent selective pressure on HIV and the 
potential for selection of resistant mutants.  Investigators must discuss the 
choice of the follow-up HAART regimen with the Medical Monitor prior to 

TMF-13901227

initiating the new regimen with the participant.  HAART therapy should be 
initiated within 4 weeks ( 7 days) after the last Q4W injection, or within 8 
weeks ( 7 days) after the last Q8W injection.  The LTFU Phase will begin the 
day of the last CAB LA and/or RPV LA dose and continue for 52 weeks.  These 
participants will complete Withdrawal assessments prior to entering  into the 
LTFU Phase as per the Time and Events Schedule.  In addition, for participants 
who withdraw during the LTFU, the final visit will be considered the study 
withdrawal visit.  
• NOTE: Participants transitioning to CAB+RPV LA marketed product or 
alternative HAART (except due to safety-related reasons) do not need to enter the 
LTFU Phase.

Participants will be assessed with clinic visits at months 3, 6, 9, and 12 during the 
Follow-Up Phase.  Female participants of child bearing potential must continue to use 
adequate contraception methods (see Study Procedures Manual for list of accepted forms 
of contraception) for the entire year of follow up.   
In order to assure that participants have access to HAART during the LTFU Phase, GSK 
may supply HAART regionally or reimbursement will be provided as needed during this 
phase.  The LTFU Phase may be modified or terminated at any time during the study for 
various reasons, e.g., better understanding of risks of development of resistance as CAB 
and RPV exposures decline, regulatory approval and commercial availability, end of 
study timings, etc. 
This phase is considered study participation and participants will be followed on study 
during this time.  Additional withdrawal assessments are not required for participants 
who do not complete the LTFU Phase.

Dose Modifications: 
No dose reductions, modifications, or changes in the frequency of any components of 
each regimen will be allowed during the study beyond what is allowed within the 
protocol or directly approved by the study Medical Monitor.  Protocol waivers or 
exemptions are not allowed.  Therefore, adherence to the study design requirements is 
essential and required for study conduct. 
In exceptional circumstances, and in consultation with the Medical Monitor, Investigators 
may provide oral CAB and/or RPV as a short-term “bridging” strategy for participants 
who have begun CAB LA + RPV LA.  Should a participant need “oral bridging”, sites 
must contact the Medical Monitor for guidance on treatment strategies prior to a missed 
CAB LA + RPV LA dose.  Should a participant not notify the site in advance, the 
Medical Monitor must be contacted for further treatment guidance. 
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the accompanying Study Procedures Manual (SPM), which is available on 
the online Study Web Portal.  The SPM will provide the site personnel with 
administrative and detailed technical information. 
2. 
INTRODUCTION 
Current HIV treatment guidelines recommend first-line antiretroviral (ARV) regimens 
consisting of two nucleoside/nucleotide analogue reverse transcriptase inhibitors (NRTIs) 
as a “backbone” combined with a third agent from the non-nucleoside reverse 
transcriptase inhibitor (NNRTI), protease inhibitor (ritonavir-boosted) (PI/RTV), or 
integrase strand transfer inhibitor (INSTI) classes [BHIVA, 2016; DHHS, 2016; EACS, 
2017; IAS USA, 2016]. While these regimens are highly efficacious and generally well 
tolerated, there is growing concern about long-term toxicities, and great interest from 
patients and clinicians in unique regimens that might avoid such toxicities, and to provide 
effective long-term antiretroviral therapy ART with the most streamlined and convenient 
regimens possible. 
 
The current paradigm in the treatment of Human Immunodeficiency Virus (HIV) 
involves life-long therapy with multiple antiretrovirals.  This dependency on medical 
therapy requires additional improvements on the durability, safety and tolerability, and 
convenience of all antiretroviral classes.  Fixed-dose combinations (FDCs) have greatly 
advanced HIV treatment by allowing simplification of dosing and reducing pill burden.  
However, adherence to therapy is essential to achieve viral suppression and prevent 
emergence of resistance mutations.  Among regimens of comparable efficacy, physicians 
and HIV-1-infected patients who receive ART rate total pill burden, dosing frequency, 
and safety concerns among the greatest obstacles to achieving adherence.  Drug resistant 
virus eventually emerges in most patients who struggle with consistent adherence.  
Different HIV treatment modalities are being developed to help improve adherence and 
patient outcomes, and prevent resistance and transmission of the virus.  
There is also an increasing desire to develop nucleoside reverse transcriptase inhibitor 
(NRTI)-sparing regimens for long-term treatment of HIV infection as an approach to

avoid known NRTI-associated adverse drug reactions and long-term toxicities.  In 
addition, while there are no currently approved two-drug regimens to maintain 
suppression, simplifying treatment has long been a goal to increase treatment compliance 
and improve the quality of life for patients with HIV.   
Cabotegravir (CAB) is a potent integrase inhibitor that possesses attributes that allow 
formulation and delivery as a long-acting (LA) parenteral product.  Rilpivirine (RPV) is a 
diarylpyrimidine derivative and a potent non-nucleoside reverse transcriptase inhibitor 
(NNRTI) with in vitro activity against wild type HIV-1 and select NNRTI-resistant 
mutants.  RPV is a globally marketed product available as oral 25 mg tablets, and is also 
formulated as a LA product.  Intramuscular administration of a two-drug combination 
therapy with CAB LA plus RPV LA may offer a better tolerability and resistance profile, 
as well as improved adherence and treatment satisfaction in virologically suppressed 
patients. 
2.1. 
Study Rationale 
The overall objective of the CAB LA + RPV LA clinical development program is to 
develop a highly effective, well tolerated two drug long-acting injectable regimen which 
has the potential to offer improved treatment convenience, compliance and improved 
quality of life for individuals with HIV compared to current standard of care.  Week 96 
efficacy data from study 200056 (LATTE-2) demonstrated that 94% of patients on the 
CAB LA + RPV LA Q8W dosing arm and 87% of patients on the Q4W dosing arm 
maintained virologic suppression (HIV-1 RNA <50 c/mL), with both regimens being 
well tolerated.  LATTE-2 results justify further evaluation of CAB LA + RPV LA dosing 
regimens.  Study 201585 (ATLAS) is an ongoing Phase III study conducted to establish 
if human immunodeficiency virus type 1 (HIV-1) infected adult participants with current 
viral suppression on a regimen with 2 nucleoside reverse transcriptase inhibitors (NRTIs) 
plus a third agent, remain suppressed upon switching to CAB LA + RPV LA Q4W.  The 
current study, 207966 (ATLAS-2M) is designed to demonstrate the non-inferior antiviral 
activity of CAB LA 600 mg + RPV LA 900 mg every 8 weeks (Q8W, every 2 months) 
compared to CAB LA 400 mg + RPV LA 600 mg administered every 4 weeks (Q4W, 
monthly) for 48 weeks. This study will also provide important long-term comparative 
antiviral activity, safety, tolerability of these regimens through Week 152 of the 
Extension Phase of the study. Additionally, eligible participants (HIV-1 RNA <50 c/mL 
at Week 96) will be given an option to continue their randomized CAB LA + RPV LA 
regimen (Q4W or Q8W) in the Extension Phase of the study. 
2.2. 
Background 
It is estimated that 36.7 million people are currently living with HIV/Acquired 
Immunodeficiency Syndrome (AIDS) and that the worldwide epidemic continues to grow 
at a rate of two million new infections and cause 1.1 million deaths per year [UNAIDS, 
2016].  Chronic HIV infection in adults continues to be characterized by increased 
development of resistant virus, increasing transmission of resistant virus and issues 
associated with long term toxicity of ART.  The current paradigm in the treatment of HIV 
involves life-long therapy with multiple antiretrovirals.  This dependency on medical

therapy requires a need for continuous improvement on the durability, tolerability and 
convenience of all antiretroviral classes. 
A study by the Antiretroviral Therapy Cohort Collaboration [ART-CC, 2013] found that 
of more than 21,000 patients in a European and North American cohort on their first 
combination antiretroviral therapy (cART) regimen (either PI or NNRTI-based), 51% 
modified or interrupted their first cART regimen during a median of 28 months of 
follow-up with one third of interruptions occurring within the first 6 months of starting 
therapy.  Forty percent of all treatment interruptions were due to the secondary side 
effects or toxicities of cART, 17% were due to the desire for simplification of the 
regimen and 14% were due to patient choice. These observations have led to numerous 
“switch” ART studies, designed to understand the efficacy, safety, and tolerability of 
switching patients from one regimen to another. 
Previous studies have evaluated switches to ritonavir-boosted PI monotherapy in 
virologically suppressed patients [Bierman, 2009 and Arribas, 2012].  These studies 
suggest that simplifying from a three drug dual class regimen to a single boosted protease 
inhibitor may be a safe and effective option for the majority of participants studied, who 
have effectively maintained viral suppression.  In the OLE study, virologically 
suppressed (HIV-1 RNA <50 c/mL) HIV-1 infected participants receiving a lopinavir-
ritonavir (LPV/r) + lamivudine (3TC) or emtricitabine (FTC) based NRTI regimen 
simplified to a dual regimen of LPV/r + 3TC or FTC.  In a modified Intent-to-Treat (m-
ITT) analysis, dual therapy with LPV/r + 3TC demonstrated non-inferiority efficacy and 
comparable safety to LPV/r + 2 NRTIs [Arribas, 2015].   
The 200056 study (GlaxoSmithKline Document Number 2013N168152_05, Study 
[LATTE-2]) is an ongoing Phase 2b study designed to assess the induction of virologic 
suppression with CAB 30 mg daily + two NRTIs, followed by a maintenance period 
where subjects are randomized (1:2:2) to continue on oral CAB 30 mg + two NRTIs or 
switch to an IM injection of CAB LA + RPV LA administered Q4W or Q8W.  A total of 
309 participants were enrolled and treated. 
During the Induction Phase there was a rapid and sustained decline in HIV-1 RNA, with 
91% of participants (282/309) achieving HIV-1 RNA <50 c/mL through 20 weeks of 
therapy.  There was a single participant (with known compliance issues) with confirmed 
virologic failure during the Induction period.  Virologic testing revealed no treatment 
emergent phenotypic or genotypic resistance in this participant. 
The primary endpoint for 200056 was the Week 32 proportion of participants with HIV-1 
RNA <50 c/mL (Snapshot, Intent-to-Treat Maintenance Exposed population [ITT-ME]). 
Following virologic suppression on three drug oral therapy in the Induction Phase, 286 
participants qualified to enter randomization at the Day 1 visit, and were subsequently 
randomized 2:2:1 onto once every 4 weeks intramuscular (IM) injections with CAB LA + 
RPV LA every 4 weeks (Q4W), once every 8 weeks (Q8W) IM injections with CAB LA 
+ RPV LA or continuation of oral CAB + NRTIs, respectively.  Through 32 weeks of 
two-drug maintenance therapy, 95% (Q8W) and 94% (Q4W) of participants on injectable 
dosing were virologic successes, compared to 91% of participants continuing three drug

oral CAB + NRTIs, meeting pre-specified criteria for comparability between the dosing 
arms.   
Week 48 was a secondary endpoint for 200056, and permitted the evaluation of the two-
drug long-acting combinations’ ability to maintain the virologic suppression 
demonstrated at Week 32.  At Week 48, 92% (Q8W) and 91% (Q4W) of participants 
receiving injectable dosing had a sustained virologic response (HIV-1 RNA <50 c/mL) 
compared to 89% of participants continuing oral CAB + 2 NRTIs.  Week 96 efficacy data 
from study 200056 (LATTE-2) demonstrated that 94% of patients on the CAB LA + 
RPV LA Q8W dosing arm and 87% of patients on the Q4W dosing arm maintained 
virologic suppression (HIV-1 RNA <50 c/mL), with both regimens being well tolerated.  
At Week 48, 10 subjects met virologic nonresponse criteria (Q8W, n=8; Q4W, n=1; oral 
CAB +2 NRTIs, n=1).  For the Q8W IM arm, 4 subjects with virologic nonresponse at 
Week 48 (HIV-1 RNA >50 c/mL) were re-suppressed with HIV-1 RNA <50 c/mL at 
Week 96 without a change in therapy.  Of 5 Q8W subjects with virologic nonresponse at 
Week 96, two had HIV-1 RNA 50 c/mL at Week 96 (one of which had HIV-1 50 c/mL 
at Week 48), one discontinued due to protocol-defined virologic failure at Week 4, one 
withdrew consent due to intolerability of injections at Week 8, and one withdrew due to 
investigator discretion at Week 48 while not suppressed (and subsequently confirmed as a 
protocol-defined virologic failure).  One of the two subjects with HIV-1 RNA >50 c/mL 
at Week 96 remained on the study and had HIV-1 levels <50 c/mL at the next scheduled 
visit.  Through 96 weeks, no subjects in the Q4W arm failed for virologic reasons.  The 
Q4W subject with virologic nonresponse at Week 48 (HIV-1 RNA, 59 c/mL) remained 
on the study beyond Week 48 and had subsequent viral re-suppression with HIV-1 
<50 c/mL at Week 96.  CAB LA + RPV LA was well tolerated through Week 96 for both 
the Q8W and Q4W dosing regimens, as demonstrated by a low discontinuation rate due 
to AEs, including injection site reaction (ISR) related AEs in either dosing arm, with no 
significant dose-dependent trends in safety parameters.  Through Week 96, the proportion 
of AEs leading to withdrawal during the study Maintenance Period was low across all 
arms (Q8W IM: n=2, 2%; Q4W IM: n=8, 7%; Oral CAB; n=1, 2%), with only one 
additional AE leading to withdrawal since the Week 48 analysis.   
Long-acting two class therapy consisting of CAB LA + RPV LA as an IM regimen has 
the benefit of being a NRTI-sparing regimen for long-term treatment of HIV infection 
which will avoid known NRTI-associated adverse drug reactions and long-term 
toxicities.  Additionally, a two-drug combination therapy with CAB LA plus RPV LA 
may offer a better tolerability and resistance profile, as well as improved adherence and 
treatment satisfaction in virologically suppressed participants improving the quality of 
life for patients with living with HIV.   
The primary objective of ATLAS-2M is to demonstrate the non-inferior antiviral activity 
of CAB LA 600 mg + RPV LA 900 mg every 8 weeks (Q8W, every 2 months) compared 
to CAB LA 400 mg + RPV LA 600 mg administered every 4 weeks (Q4W, monthly) for 
48 weeks.   ATLAS-2M will also evaluate long-term antiviral and immunologic effects, 
safety and tolerability, and viral resistance of the Q8W and Q4W regimens for a 
minimum of 100 weeks.  In addition, ATLAS-2M will assess patient reported health-

Benefit/Risk Assessment 
Summaries of findings from both clinical and non-clinical studies conducted with oral 
and LA CAB and LA RPV can be found in the current Investigator’s Brochures. 
The following section outlines the risk assessment and mitigation strategy for this 
protocol:   
2.3.1. 
Risk Assessment 
Oral CAB and CAB LA (GSK1265744/GSK1265744 LA) 
Since CAB exposure in humans with or without HIV infection is limited, the clinical 
safety profile in humans has yet to be fully elucidated.  The following risks have 
primarily been identified during routine preclinical testing and/or from the clinical trial 
experience to date and are considered of potential relevance to clinical usage in the 
context of this protocol.  Additional information about the clinical experience to date and 
possible risks associated with treatment using CAB can be found in the Summary of Data 
and Guidance for the Investigator section of the IB.

Drug Induced Liver 
Injury (DILI) 
 
Less than 1% of  participants in the CAB 
program to date have developed transaminitis 
(elevated liver transaminases characterised by 
predominant alanine aminotransferase (ALT) 
elevation).  In most participants, transient 
transaminitis was explained by acute hepatitis C 
infection (majority) and other systemic 
infections.  In a small number of participants, 
there was not an alternative explanation, 
suggesting a mild form of drug induced liver 
injury (DILI) without hepatic dysfunction, which 
resolved upon withdrawal of treatment with 
CAB.  
 
• Exclusion criteria as described in Section 5.2 
will prohibit participants with significant liver 
impairment based on screening liver chemistry 
including transaminases (ALT and Aspartate 
aminotransferase [AST]) as well on prior 
medical history. Participants with a history of 
chronic liver disease with ongoing 
inflammation and/or fibrosis will have 
additional confirmatory assessments to confirm 
suitability for entry into the study.  
 
• A 4-week oral lead- in Phase is being 
implemented in this study, where all 
participants will receive oral CAB prior to the 
administration of IM CAB to assess individual 
safety and tolerability  
 
• Liver transaminases (ALT and AST) will be 
monitored throughout this study (refer to Time 
& Events Table, Section 7.1) and the liver 
chemistry stopping criteria will be adopted as 
described in Section 5.5.1.1 of this protocol. 
Participants will be withdrawn from CAB 
treatment where no compelling alternative 
cause is identified and DILI is suspected.

Injection Site Reactions 
(ISRs) 
 
Clinical, experience to date has demonstrated 
ISRs occur in the majority of exposed 
participants treated with CAB LA but are 
generally mild (Grade 1) or moderate (Grade 2) 
and include events of pain, tenderness, erythema, 
or nodule formation of several days duration 
(median duration for individual events <1 week). 
ISRs may occur more than once in an individual 
participant receiving multiple injections.  
Although some Grade 3 ISRs were reported, 
overall ISRs have been well tolerated and have 
not to date been associated with an excess of 
participants’ withdrawal.  
None of the ISRs reported to date have been 
serious.   
• Administration advice will be given to 
minimize risk of poor administration technique 
giving rise to injection site reactions.  Advice 
on care, monitoring, natural course, and 
treatment of ISRs is given in study 
documentation  
 
• Advice will be given to participants on care of 
injection site on day/days immediately post 
administration, use of analgesia, compresses 
where appropriate. 
 
• Participants will be closely monitored for ISRs 
particularly for signs of pain, tenderness, 
infections, erythema, swelling, induration, or 
nodules (granulomas or cysts) throughout the 
study.   
 
• Complications of ISRs such as infections 
(abscess, cellulitis) and collections of fluid 
requiring drainage will be monitored

Hypersensitivity 
Reactions (HSR) 
 
Hypersensitivity reactions have been reported as 
uncommon occurrences with integrase inhibitors, 
including the closely related compound 
dolutegravir, and were characterized by rash, 
constitutional findings, and sometimes, organ 
dysfunction, including liver injury.  
While there have been no clinical cases of 
hypersensitivity to CAB to date, there is a 
theoretical risk of systemic or severe 
hypersensitivity reactions with or without hepatic 
symptoms associated with use of IM CAB.  The 
long exposures anticipated after IM CAB 
injection may complicate the management of a 
drug hypersensitivity reaction, were it to occur. 
 
• The risk of developing a hypersensitivity 
reaction post administration of IM CAB will be 
minimized by the use of a 4-week oral lead-in 
of oral CAB to determine individual safety and 
tolerability prior to the introduction of IM 
CAB.  
 
• Clinical assessments, laboratory tests (including 
liver transaminases) and vital signs will be 
performed throughout this study (refer to Time 
& Events Table, Section 7.1). Results from 
these assessments may aid early detection of 
HSR.  
 
• Oral CAB will be withdrawn immediately for 
cases with suspected HSR during the oral CAB 
lead-in phase and would not proceed to the 
injection phase.  Participants in the injection 
phase would not receive further injections.  
During oral and IM CAB treatment, any HSR 
reactions that occur would be managed 
supportively.

Effects in pregnancy seen 
in non-clinical studies 
In animal reproduction studies, CAB when 
administered to rats at > 30 times the systemic 
exposure at the maximum recommended oral 
human dose (MRHD) of 30 mg during 
organogenesis through delivery, had adverse 
effects on labor and delivery that may be related 
to a delay in the onset of parturition, resulting in 
increased fetal mortality (stillbirths) and neonatal 
deaths immediately after birth. 
A delay in the onset of parturition, increased 
stillbirths and neonatal deaths were observed in a 
rat pre- and postnatal development study at 
greater than 30 times the exposure at the 
recommended human dose (RHD). No evidence 
of adverse developmental outcomes was observed 
with oral cabotegravir in rats or rabbits (greater 
than 30 times or similar to (approximately 0.7 
times) the exposure at the RHD, respectively) 
given during organogenesis. 
The clinical significance of these finding in 
humans is unknown.  
For pregnant participants remaining in the study, 
refer to Appendix 11 for additional data regarding 
CAB and pregnancy.

in this study and women of childbearing 
potential (WOCBP) are required to adopt

Female participants on LA dosing who become 
pregnant will have exposures throughout 
pregnancy due to the long half-life and PK tail of 
CAB/RPV. Pregnant participants who are 
withdrawn from study and are initiated on an 
alternative oral ART regimen consisting of either 
2 or 3 antiretrovirals to protect the life of the 
mother and for the prevention of MTCT, 
potentially expose the fetus to additional ARVs 
during gestation (in some cases upwards of 5 
antiretrovirals). 
 
Potential effects in 
females exposed to 
dolutegravir during 
conception and early 
pregnancy 
A preliminary analysis of an ongoing birth 
outcome surveillance study in Botswana 
involving women exposed to dolutegravir (DTG), 
a different molecule in the same integrase class of 
medications as CAB, identified four cases (as of 
May 2018) of neural tube defects in 426 infants 
born to mothers who were exposed to DTG-
containing regimens from the time of conception. 
In the same study, no infant born to a woman 
who started DTG during pregnancy had a neural 
tube defect, out of 2,824 women. A causal 
relationship of these events to the use of DTG has 
not been established. The incidence of neural 
tube defects in the general population ranges

from 0.5-1 case per 1,000 live births. As neural 
tube defects occur within the first 4 weeks of fetal 
development (at which time the neural tubes are 
sealed) this potential risk would concern women 
exposed to DTG at the time of conception and in 
early pregnancy.  
Recently updated data (April 2020) for this birth 
outcome study showed that among women who 
were on DTG when they became pregnant, 
7/3591 neural tube defects (NTD) occurred 
(0.19%). In comparison, NTDs were identified in 
21/19,361 (0.11%) women delivering on any 
non-DTG antiretrovirals. There was not a 
significant difference in the number of neural 
tube defects between births to women taking 
DTG and those taking other non-DTG 
antiretroviral treatments (0.09% difference).

containing divalent cations (e.g., aluminum, 
calcium, and magnesium) must be taken at least 2 
hours before or at least 4 hours after CAB.  
Participants discontinuing a LA regimen may be 
at risk for developing DDIs many weeks after 
discontinuing injectable therapy.  
Inadvertent Intravenous 
Injection (Accidental 
Maladministration) 
As with any intramuscular injection, it is possible 
that CAB LA can be inadvertently administered 
intravenously instead of intramuscularly possibly 
resulting in higher than expected concentrations 
of CAB shortly after injection and lower 
concentrations thereafter.  This could be due to 
administrator error, improper injection technique 
and / or improper needle length used based on 
body type.     
The clinical consequences of overdose with CAB 
LA are currently unknown.  HIV-1 viral 
suppression may not be effective following 
accidental maladministration. 
 
• Training will be provided to all sites on proper 
injection technique.   
• Should IM maladministration be suspected at 
any time (e.g. suspected under or overdose or 
inadvertent IV dosing), a post dose 
electrocardiogram (ECG), vital signs, or any 
other supportive testing may be obtained at the 
discretion of the investigator, and the medical 
monitor will be notified.   
• Laboratory samples for safety parameters and 
HIV-1 RNA will be closely monitored in all 
participants.  Additionally, 2 hour post dose PK 
samples will be obtained at a few early 
timepoints for determination of CAB 
concentration and possible pharmacokinetic 
correlation with safety parameters such as ECG 
changes and virologic response.  Additionally, 
an unscheduled PK sample may be drawn 
approximately 2 hours post dosing for future 
evaluation of CAB concentrations.

study. 
 
• Complications of ISRs such as infections 
(abscess, cellulitis) and collections of fluid 
requiring drainage will be monitored  
• Significant ISRs may be photographed and 
referred to a dermatologist for specialist advice. 
Rash 
 
Some observations of rash with oral RPV have 
been reported in clinical studies executed to date 
(the majority are Grade 1 or 2).  
Severe skin and hypersensitivity reactions have 
been reported during the postmarketing 
experience, including cases of Drug Reaction with 
Eosinophilia and Systemic Symptoms (DRESS), 
with oral RPV containing regimens.  While some 
skin reactions were accompanied by constitutional 
symptoms such as fever, other skin reactions were 
associated with organ dysfunctions, including 
elevations in hepatic serum biochemistries. 
• In this study, RPV LA administration will be 
preceded by an oral RPV lead in to evaluate 
safety and tolerability in individual participants. 
• Participants with a Grade 1 or 2 rash will be 
allowed to continue treatment  , depending on 
the clinical judgment of the investigator. 
 
• All participants experiencing a Grade 3 or 4 rash 
should discontinue their ARV medication (study 
medication and background regimen) and be 
withdrawn from the study. 
 
• All rash events should be assessed with special 
attention to systemic symptoms, laboratory 
abnormalities, or mucosal involvement.  Close 
clinical follow-up, including follow-up of 
laboratory abnormalities, and appropriate 
medical intervention, including referral to

dermatologist as appropriate, should be instituted 
for these events; daily follow-up is 
recommended for 5 days from the onset of the 
event to monitor for progression of the event.  
See Section 7.4.5.13 for additional guidance on 
management of rash events. 
Development of 
Resistance 
 
Residual concentrations of RPV LA can remain in 
the systemic circulation of participants who 
stopped treatment (e.g., for tolerability issues or 
treatment failure) for prolonged periods (months to 
more than a year, in some subjects, McGowan, 
2016).   
 
Participants discontinuing a LA regimen may be at 
risk for developing resistance to RPV many weeks 
after discontinuing injectable therapy. 
• After participants stop RPV LA, Oral HAART 
regimens will be prescribed within 4 weeks after 
the last Q4W dose or within 8 weeks after the 
last Q8W dose, and following consultation with 
the medical monitor.  This would be anticipated 
to result in rapid resuppression of HIV-1 RNA 
thus minimizing the risk of emergent resistance 
 
• The Sponsor will continue to monitor 
participants in this study who discontinue a LA 
regimen  for a minimum of 52 weeks from the 
time of the last LA administration. 
Drug-Drug Interactions 
(DDIs) 
For a complete listing of permitted and prohibited 
concurrent medications for RPV and RPV LA, 
refer to Section 6.13 
RPV LA should not be co-administered with the 
following medicinal products, as significant 
decreases in RPV plasma concentrations may 
occur (due to CYP3A enzyme induction), which

Oral RPV administration only:   
- Antacid products containing divalent cations 
(e.g., aluminum, calcium, and magnesium) 
must be taken at least 2 hours before or at least 
4 hours after RPV. 
- H2-antagonists must be taken at least 12 hours 
before or at least 4 hours after taking RPV. 
- RPV should not be co-administered with 
proton pump inhibitors, such as esomeprazole,

Inadvertent 
Intravenous Injection 
(Accidental 
Maladministration) 
As with any intramuscular injection, it is possible 
that RPV LA can be inadvertently administered 
intravenously instead of intramuscularly possibly 
resulting in higher than expected concentrations of 
RPV shortly after injection and lower 
concentrations thereafter.  This could be due to 
administrator error, improper injection technique 
and / or improper needle length used based on 
body type.   
In addition, HIV-1 viral suppression may not be 
effective following accidental intravenous 
maladministration. 
Systemic reactions following RPV LA injections 
have been observed in clinical trials. These occur 
infrequently (in less than 0.5% of participants) and 
typically begin to resolve within minutes of the 
injection, however some participants  required 
supportive care. Where timely PK data was 
available, high RPV PK plasma concentrations 
have been observed which may have resulted from 
an accidental partial IV injection of RPV 
• Training will be provided to all sites on proper 
injection technique.   
• Should IM maladministration be suspected at 
any time (e.g., suspected under or overdose or 
inadvertent IV dosing), post dose ECG 
monitoring and vital signs or any other 
supportive testing may be obtained at the 
discretion of the investigator, and the medical 
monitor notified 
• Laboratory samples for safety parameters and 
HIV-1 RNA will be closely monitored in all 
participants.  Additionally, 2-hour post dose PK 
samples will be obtained at a few early 
timepoints for determination of RPV 
concentration and possible pharmacokinetic 
correlation with safety parameters such as ECG 
changes and virologic response. Additionally, an 
unscheduled PK sample may be drawn 
approximately 2  hours post dosing for future 
evaluation of RPV concentrations.

• Trained personnel will perform venipuncture 
Risks of ECG pad

Participants will be required to have ECG tracings

personnel and effort made to minimize contact 
time for application of the pads. 
Risk of Treatment Failure This study employs a novel 2 drug LA ART 
maintenance regimen for the treatment of HIV-1 
infection that remains experimental.  Both IM 
CAB and RPV have demonstrated antiviral 
activity in large clinical studies and the two drug 
combination dosed Q4W has demonstrated 
sustained antiviral activity in studies 200056, 
201584 and 201585 however the efficacy of 
Q8Wdosing remains under evaluation.    
Doses of the CAB LA and RPV LA have been 
selected to achieve exposures that are expected to 
maintain virologic efficacy on the basis of 
available data with the oral and LA formulations. 
 
• Viral loads and CD4+ cell counts will be closely 
monitored throughout the study (maintenance 
and extension phases), allowing for early 
detection of failing treatment.  Where confirmed 
virological failure occurs, participants would be 
discontinued from study drugs and transferred to 
an oral HAART regimen. 
• Plasma samples will be collected throughout the 
Maintenance Phase for determination of CAB 
and RPV concentration and possible 
pharmacokinetic correlation with virologic 
response.

Summary of Data/Rationale for Risk 
Mitigation Strategy 
Due to administration error, it is possible that a 
participant could receive an inadequate dose of 
CAB LA or RPV LA.  Sub-therapeutic 
concentrations of either CAB LA or RPV LA 
could lead to virologic failure and possibly the 
development of viral resistance.

Other Clinically Relevant Information 
Additional details concerning safety observations from clinical studies and for which a 
causal association has not been established or which are of minimal clinical significance 
may be found in the Investigator’s Brochures .   
 
Adverse Events of Special Interest: 
 
Seizure 
Several cases of seizure have occurred during the cabotegravir program. These cases 
have had alternative explanations for their occurrence. Overall, there is not convincing 
evidence that cabotegravir exposure may be causally associated with seizure or with 
reduction of seizure threshold, due to the low frequency of reports, the confounders 
present in the cases received to date and lack of any pre-clinical signal or identified 
plausible mechanism. However, seizure and seizure-like events are considered as AEs of 
special interest for CAB.  Subjects with an unstable or poorly controlled seizure disorder 
will be excluded from study participation. All cases of prior seizure history should be 
discussed with the Medical Monitor prior to enrolment. Report any cases of seizure or 
seizure like events immediately. 
2.3.2. 
Benefit Assessment 
The antiviral activity against HIV-1 of CAB has been well established through Phase 2 
and Phase 3 studies. RPV is an established antiviral agent against HIV-1 in treatment 
naive patients, with long term durability (>96 weeks in Phase 3 and >240 weeks in Phase 
IIb). 
Participants receiving CAB LA + RPV LA are anticipated to benefit from maintenance of 
virological suppression using LA agents. Participants randomized to receive CAB LA+ 
RPV LA Q4W or Q8W weekly dosing will not need to take concomitant daily oral 
therapy.  Adherence in these participants is expected to be improved and will be directly 
observed during IM injections. Efficacy of this two-drug regimen, as IM agents, has been 
demonstrated through Week 96 of the ongoing 200056, 201584 and 201585 studies. The 
reduction in ART, and the discontinuation of NRTIs, may offer long term safety and 
tolerability benefits in these participants. 
2.3.3. 
Overall Benefit:Risk Conclusion 
Taking into account the measures taken to minimize risk to participants participating in 
this study, the potential risks identified in association with CAB LA and RPV LA Q4W 
and Q8W regimens, and the study as a whole are justified by the anticipated benefits that 
may be afforded to treatment-experienced patients with HIV-1 infection.

STUDY DESIGN 
4.1. 
Overall Design 
Study 207966 (Antiretroviral Therapy as Long Acting Suppression every 2 Months-
ATLAS-2M) is a Phase III, randomized, open-label, active-controlled, multicenter, 
parallel-group, non-inferiority study designed to assess the antiviral activity and safety of 
CAB LA + RPV LA administered every 4 weeks compared CAB LA + RPV LA 
administered every 8 weeks in approximately 1020 adult HIV-1 infected patients.   
Two groups of patients who fulfill eligibility requirements will be randomized (1:1) at 
Day 1 to receive CAB LA + RPV LA Q4W, or CAB LA + RPV LA Q8W regimen for at 
least 100 weeks:  
Group 1: Patients randomized from current ART Standard of Care (SOC) therapy 
Patients randomized from current ART SOC therapy, including those enrolled to the 
“current ART” arm of the ATLAS study following completion of the Week 52 visit (at

minimum), will begin oral therapy with CAB 30 mg + RPV 25 mg once daily at Day 1 
for 28 days (3 days) to determine individual safety and tolerability prior to receiving 
CAB LA + RPV LA Q4W, or CAB LA + RPV LA Q8W.  For patients on SOC 
transitioning from the ATLAS trial, eligibility for ATLAS-2M can be determined once 
the final central lab results from ATLAS are available and safety parameters have been 
reviewed. 
Group 2: Patients currently receiving CAB LA + RPV LA Q4W 
At Day 1, patients entering ATLAS-2M from ATLAS and currently receiving CAB LA + 
RPV LA Q4W (including both those who were originally randomized to Q4W in the 
Maintenance phase of ATLAS and those who transitioned from SOC to the Q4W 
regimen within the Extension Phase of ATLAS) will be randomized 1:1 to either 
continue Q4W administration or transition to Q8W administration of CAB LA + RPV 
LA.  The first injection visit for ATLAS-2M can be performed once the final central lab 
results from ATLAS are available and safety parameters have been reviewed, and the 
ATLAS Week 52 visit (at minimum) has been completed.  Participants will continue to 
receive CAB LA + RPV LA Q4W injections as scheduled within the ATLAS trial until 
their eligibility for ATLAS-2M can be fully evaluated and the participant is re-
randomized (Q4W or Q8W).  If determined to be ineligible for ATLAS-2M, those 
participants can elect to continue participation in ATLAS or withdraw from the ATLAS 
study.  
Participants in ATLAS-2M who successfully complete Week 100 (without meeting study 
defined withdrawal criteria) will be given the option to continue to receive their 
randomized treatment (CAB LA + RPV LA administered Q4W or Q8W) in the Extension 
Phase through Week 152 and until the study treatment is either locally approved and 
commercially available within the local sector (including through local 
public/government health sectors), the participant no longer derives clinical benefit, the 
participant meets a protocol-defined reason for discontinuation or until development of 
either CAB LA + RPV LA Q4W and/or Q8W is terminated.  Alternatively, participants 
can choose to complete study participation and enter the 52-week LTFU Phase of the 
study. 
 
Any participant who receives at least one dose of CAB LA and/or RPV LA and 
discontinues the CAB LA + RPV LA regimen for any reason will enter a 52-week LTFU 
Phase.  Those participants must remain on suppressive highly active antiretroviral therapy 
(HAART) for at least 52 weeks after the last dose of CAB LA and/or RPV LA. 
In order to achieve balance across the treatment arms, randomization will be stratified by 
prior CAB + RPV Exposure: 0 weeks, 1-24 weeks, >24 weeks.  The primary endpoint for 
the study is the proportion of participants with HIV-RNA greater than or equal to 
50 c/mL (Virologic Failure) at Week 48 as per Food and Drug Administration (FDA) 
Snapshot algorithm using the Intent-to-Treat Exposed (ITT-E) population.  The 
proportion of participants with plasma HIV-1 RNA <50 c/mL at Week 48 using the FDA 
Snapshot algorithm (Missing, Switch or Discontinuation = Failure, ITT-E population) is a 
key secondary endpoint comparison.

The sample size of 1020 provides 85% power to demonstrate non-inferiority in the 
primary endpoint at Week 48 using a 4% margin, assuming a true 3% failure rate for 
Q8W CAB LA + RPV LA and a 2% failure rate for the Q4W CAB LA + RPV LA arm 
and a 2.5% one-sided alpha level.

Treatment Groups and Duration 
4.2.1. 
Screening Phase (Up to 35 days) 
Informed consent must be obtained prior to any study procedures, including any 
Screening assessment. 
Participants will be involved in a Screening period of up to 35 days and may be re-
screened once.  Participants who are randomized into the trial and subsequently 
withdrawn from the study, for any reason, may not be re-screened.  Participants may be 
randomized as soon as all eligibility requirements have been confirmed at the site. 
For participants transitioning from the ATLAS study, eligibility to transition to ATLAS-
2M at Week 52 (at the earliest) will be determined once the final central lab results from 
ATLAS, following (at minimum) completion of the ATLAS Week 48 visit are available

and safety parameters have been reviewed.  Separate Screening Labs will be utilized to 
inform eligibility for ATLAS-2M; however, in some occasions and upon consultation 
with the Medical Monitor, individual lab results and safety data from the final visit of the 
ATLAS study can be considered towards informing eligibility for the ATLAS-2M study 
as long as all other Screening and eligibility criteria are met.     
4.2.2. 
Maintenance Phase (Day 1 up to Week 100) 
There are two ways in which study participants may transition to the LA regimen, either 
directly from oral SOC or from Q4W dosing from ATLAS.

4.2.2.1. 
Patients randomized to LA dosing from current ART SOC therapy: 
All participants randomized from current ART SOC therapy (including those 
transitioning from SOC in ATLAS and new study participants) will begin oral therapy 
with CAB 30 mg + RPV 25 mg once daily at Day 1 for 4 weeks to determine individual 
safety and tolerability prior to administration of CAB LA + RPV LA.  The oral lead-in 
period is part of the Maintenance Phase and will therefore be included within the planned 
analyses. 
The final dosing of current daily oral ART regimen should occur the day prior to 
randomization to avoid overlap of treatment regimens however, if the participant takes 
current ART prior to coming into the clinic, randomization and initiation of oral CAB 
and RPV should continue as planned for Day 1.  At the Week 4a visit, safety assessments 
(including e.g., clinical chemistries) will be performed as per the Time and Events Table 
to determine individual safety and tolerability prior to the initial administration of CAB 
LA + RPV LA.  Dosing of CAB LA + RPV LA Q4W or Q8W will initiate at the Week 
4b visit once safety labs from Week 4a are available and have been reviewed. 
Subjects receiving oral SOC treatment and randomized to Q4W injections will receive 
loading doses of CAB LA 600 mg + RPV LA 900 mg on Week 4b followed by 
maintenance injections of CAB LA 400 mg + RPV LA 600 mg every 4 weeks thereafter.   
Subjects receiving oral SOC treatment and randomized to Q8W injections will receive 
doses of CAB LA 600 mg + RPV LA 900 mg on Week 4b and Week 8 followed by 
identical maintenance dose injections every 8 weeks thereafter. 
All injections should be planned as single injections per drug.

4.2.2.1.1. IM injections every 4 weeks (Q4W from SOC): 
Week 4b visit only - CAB LA 600 mg + RPV LA 900 mg, each given as 1 X 3 mL IM 
injection 
Week 8 visit and Q4W thereafter - CAB LA 400 mg IM + RPV LA 600 mg IM every 
4 weeks for 100 weeks, each given as 1 X 2 mL IM injection 
At Week 4b, participants will return to the clinic, take the last oral dose (CAB 30 mg + 
RPV 25 mg), and receive the first CAB LA (600 mg) + RPV LA (900 mg) injections 
(within 2 hours of the final oral dose of CAB + RPV).  The first injections with IM CAB 
LA + RPV LA at Week 4b can be performed once central lab results are available and 
safety parameters are reviewed from the Week 4a visit.   
The second and third IM injections with CAB LA 400 mg and RPV LA 600 mg will be 
performed at Week 8 and Week 12.  There will be a -7-day dosing window for the second 
and third IM injections such that the second injection occurs within the window of 
Week 7 and Week 8 but no later than Week 8 and the third injection occurs within the 
window of Week 11 and Week 12 but no later than Week 12.  Subsequent injections with 
CAB LA 400 mg and RPV LA 600 mg will occur every 4 weeks (7 days) thereafter.  In 
addition, starting after the Week 16 injection, the interval between injection visits will be 
limited to a maximum of 5 weeks.  The Medical Monitor must be contacted to discuss 
individual participant case management if the length of time between injections exceeds 
or is projected to exceed 5 weeks. 
4.2.2.1.2. IM injections every 8 weeks (Q8W from SOC): 
Week 4b visit – CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM 
injection 
Week 8 visit- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM 
injection 
Week 16 visit and Q8W thereafter - CAB LA 600 mg + RPV LA 900 mg IM, every 8 
weeks for 100 weeks, each given as 1 X 3 mL IM injection 
At the Week 4b visit, subjects will return to the clinic, take their last oral dose (CAB 
30 mg + RPV 25 mg), and receive the first CAB LA (600 mg) + RPV LA (900 mg) 
injections (within 2 hours of the final oral dose of CAB + RPV).  The first injections with 
IM CAB LA + RPV LA at Week 4b can be performed once central lab results are 
available and safety parameters are reviewed from the Week 4a visit.   
The second loading injection will be administered at Week 8 (CAB LA 600 mg + RPV 
LA 900 mg, with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring 
every 8 weeks thereafter.  There will be a -7-day dosing window for the second and third 
IM injections such that the second injection occurs within the window of Week 7 and 
Week 8 but no later than Week 8 and third injection occurs within the window of Week 
15 and Week 16 but no later than Week 16.  Subsequent injections with CAB LA 600 mg 
and RPV LA 900 mg will occur every 8 weeks (7 days).  Starting after the Week 16

injection, the interval between injection visits will be limited to a maximum of 9 weeks.  
If the length of time between injections exceeds, or is projected to exceed 9 weeks, the 
Medical Monitor must be contacted to discuss individual participant case management.   
4.2.2.2. 
Participants transitioning from ATLAS and currently receiving CAB LA 
+ RPV LA Q4W 
Subjects receiving Q4W injections within ATLAS and randomized to receive Q4W 
injections in Study 207966 will continue receiving maintenance injections Q4W as 
scheduled and will not require a loading dose on Day 1. 
Subjects receiving Q4W injections within ATLAS and randomized to receive Q8W 
injections in Study 207966 will receive doses of CAB LA 600 mg + RPV LA 900 mg on 
Day 1, one month after their last Q4W maintenance dose, in order to align with Day 1 of 
study randomization.  Subjects will not require an intermediate dose at Week 4 and will 
receive their next Q8W maintenance injections at Week 8 and Q8W thereafter.   
Participants transitioning from the ATLAS study and on CAB LA + RPV LA Q4W 
treatment will be randomized at Day 1 to either continue Q4W administration or 
transition to Q8W administration of CAB LA + RPV LA.  The first injection visit for the 
ATLAS-2M study can be performed once the final central lab results from the ATLAS 
study are available and safety parameters have been reviewed.  Screening labs 
determining eligibility for ATLAS-2M can be collected at Week 48 (at minimum) for 
participants originally randomized to the Q4W arm within ATLAS.  Screening labs for 
participants who transitioned from SOC to Q4W injections within the ATLAS Extension 
Phase may be obtained at ATLAS Week 56b (following the CAB + RPV Oral lead-in 
period) or at subsequent ATLAS visits after receiving one set or a short course of Q4W 
injections.  The transition from the final ATLAS to ATLAS-2M Day 1 dosing must occur 
4 weeks (7 days) from the final injections received in ATLAS  
Dosing for participants transitioning from CAB LA + RPV LA Q4W in ATLAS is as 
follows: 
4.2.2.2.1. IM injections every 4 weeks (Q4W from ATLAS Q4W): 
Starting at Day 1, all injections will continue with maintenance doses of CAB LA 400 mg 
and RPV LA 600 mg administered every 4 weeks (7 days).  In addition, the time 
between injection visits will be limited to a maximum of 5 weeks.  The Medical Monitor 
must be contacted if the length of time between injections exceeds or is projected to 
exceed 5 weeks. 
4.2.2.2.2. IM injections every 8 weeks (Q8W from ATLAS Q4W): 
Participants transitioning from ATLAS and randomized to receive CAB LA + RPV LA 
Q8W injections will initiate Q8W dosing at the Day 1 visit as follows:  
Day 1- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM injection 
Week 8 and Q8W thereafter- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 
3 mL IM injection 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
61 
 
The second loading injection will be administered at Week 8 (CAB LA 600 mg + RPV 
LA 900 mg), with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring 
every 8 weeks thereafter.  There will be a -7-day dosing window for the second and third 
IM injections such that the second injection occurs within the window of Week 7 and 
Week 8 but no later than Week 8 and third injection occurs within the window of 
Week 15 and Week 16 but no later than Week 16.  Subsequent injections with CAB LA 
600 mg and RPV LA 900 mg will occur every 8 weeks (7 days).  Starting after the 
Week 16 injections, the interval between injection visits will be limited to a maximum of 
9 weeks.  If the length of time between injections exceeds, or is projected to exceed 9 
weeks, the Medical Monitor must be contacted to discuss individual participant case 
management.   
The primary study analysis will consist of data collected through the Week 48 visit.  A 
single repeat of HIV-1 RNA for any participant with a HIV-1 RNA 50 c/mL at Week 
48, Week 96, or Week 152 must be performed.  The retest should be scheduled as soon as 
possible (but no later than 4 weeks from the Week 48,  96 or 152 visits, respectively) and 
will inform the Week 48, 96, or 152 virological endpoint, respectively.   
4.2.3. 
Extension Phase 
Participants who successfully complete 96 Weeks of CAB LA + RPV LA treatment in 
the Maintenance Phase will continue to have access to their randomized treatment Q4W 
or Q8W CAB LA + RPV LA in the Extension Phase through Week 152 and until study 
treatment is either locally approved and commercially available within the local sector 
(including through local public/government health sectors), the participant no longer 
derives clinical benefit, the participant meets a protocol-defined reason for 
discontinuation or until development of either CAB LA + RPV LA Q4W and/or Q8W is 
terminated.  For participants randomized to Q4W arm, dosing visits will continue to 
occur every 4 weeks with CAB LA 400 mg and RPV LA 600 mg.  For participants 
randomized to the Q8W arm, dosing visits will continue to occur every 8 weeks with 
CAB LA 600 mg and RPV LA 900 mg.  Safety and efficacy assessments will be 
conducted as per the Time and Events Schedule.  
Participants choosing to not enter the Extension phase can complete their study 
participation at the Week 100 visit and enter into the LTFU Phase as required.  
Participants who choose to continue on to the Extension Phase will need to be assessed 
for eligibility and will continue on their current CAB LA + RPV LA regimen while 
eligibility is being confirmed.  A single repeat of HIV-1 RNA for any participant with a 
HIV-1 RNA 50 c/mL and < 400 c/mL at Week 96, or Week 152 must be performed.  
The retest should be scheduled as soon as possible (but no later than 4 weeks from the 
Week 96 or Week 152 visit).  Participants with HIV-1 RNA <50 c/mL upon retest are 
eligible to enter the Extension Phase.  Participants with HIV-1 RNA ≥400 c/mL at 
Week 96 are not eligible to enter the Extension Phase, will not be allowed a repeat to 
determine eligibility, and will therefore be withdrawn from the study.  Eligibility to enter 
the Extension Phase for any participants with a retest HIV-1 RNA >50 c/mL and <400 
c/mL will require approval by the study Medical Monitor.

Participants not eligible to enter the Extension Phase or choosing not to participate in the 
Extension Phase will end their study treatment and enter the LTFU Phase. Sites may be 
reimbursed for up to a one-month supply of antiretroviral medication to facilitate 
transition to non-study ART for participants that do not qualify for the Extension Phase. 
4.2.4. 
LTFU Phase – IM Regimen Only 
• Any participant who receives at least one dose of CAB LA and/or RPV LA and 
discontinues the CAB LA + RPV LA regimen for any reason before CAB LA + 
RPV LA marketed product is locally available must enter the LTFU Phase. 
Participants must remain on suppressive HAART for at least 52 weeks after the 
last dose of CAB LA and/or RPV LA in order to prevent selective pressure on 
HIV and the potential for selection of resistant mutants.  Investigators must 
discuss the choice of the follow-up HAART regimen with the Medical 
Monitor prior to initiating the new regimen with the participant.  HAART 
therapy should be initiated within 4 weeks ( 7 days) after the last Q4W 
injection or within 8 weeks ( 7 days) after the last Q8W injection.  The 
LTFU will begin the day of the last CAB LA and/or RPV LA dose and continue 
for 52 weeks.  These participants will complete Withdrawal assessments and will 
then enter into the LTFU Phase as per the Time and Events Schedule.  In addition, 
for participants who withdraw during the LTFU Phase, the final visit will be 
considered the study withdrawal visit. 
• Where the CAB LA + RPV LA marketed product is locally available, only 
participants that discontinue the CAB LA + RPV LA regimen for safety-related 
reasons included in Section 5.5 must enter the LTFU Phase. Participants must 
remain on suppressive HAART for at least 52 weeks after the last dose of CAB 
LA and/or RPV LA in order to prevent selective pressure on HIV and the 
potential for selection of resistant mutants.  Investigators must discuss the 
choice of the follow-up HAART regimen with the Medical Monitor prior to 
initiating the new regimen with the participant.  HAART therapy should be 
initiated within 4 weeks ( 7 days) after the last Q4W injection or within 8 
weeks ( 7 days) after the last Q8W injection.  The LTFU Phase will begin the 
day of the last CAB LA and/or RPV LA dose and continue for 52 weeks.  These 
participants will complete Withdrawal assessments and will then enter into the 
LTFU Phase as per the Time and Events Schedule.  In addition, for participants 
who withdraw during the LTFU Phase, the final visit will be considered the study 
withdrawal visit.  
• NOTE: Participants transitioning to CAB+RPV LA marketed product or 
alternative HAART (except due to safety-related reasons) do not need to enter the 
LTFU Phase however the transition plan to marketed product (either CAB+RPV 
LA or alternative HAART) should be done in consultation with the Central Study 
Team and the Medical Monitor.  
 
Participants will be assessed with clinic visits at months 3, 6, 9, and 12 during the LTFU 
Phase.  Female participants of child bearing potential must continue to use adequate 
contraception methods (see Study Procedures Manual for list of accepted forms of 
contraception) for the entire year of follow up.

In order to assure that participants have access to HAART during the LTFU Phase, GSK 
may supply HAART regionally or reimbursement will be provided as needed during this 
phase.  The LTFU Phase may be shortened or terminated at any time during the study for 
various reasons, e.g., better understanding of risks of development of resistance as CAB 
and RPV exposures decline, regulatory approval and commercial availability, end of 
study timings, etc. 
This phase is considered study participation and participants will be followed on study 
during this time.  A withdrawal visit is not required for participants who do not complete 
the LTFU Phase.  The participants’ last on study visit will be considered as their 
withdrawal visit. 
4.2.5. 
Dose Modifications: 
No dose reductions, modifications, or changes in the frequency of any components of 
each regimen will be allowed during the study beyond what is allowed within the 
protocol or directly approved by the study Medical Monitor.  Protocol waivers or 
exemptions are not allowed.  Therefore, adherence to the study design requirements is 
essential and required for study conduct. 
In exceptional circumstances, and in consultation with the Medical Monitor, Investigators 
may provide oral CAB and/or RPV as a short-term “bridging” strategy for participants 
who have begun CAB LA + RPV LA (see Section 6.8.1 for additional details).  Should a 
participant need “oral bridging”, sites must contact the Medical Monitor for guidance on 
treatment strategies prior to a missed CAB LA + RPV LA dose.  Should a participant not 
notify the site in advance, the Medical Monitor must be contacted for further treatment 
guidance. 
Please refer to Appendix 10 in Section 11.10 for study management information during 
the COVID-19 pandemic. 
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the accompanying Study Procedures Manual (SPM), which is available on 
the online Study Web Portal.  The SPM will provide the site personnel with 
administrative and detailed technical information. 
4.2.6. 
Independent Data Monitoring Committee 
An Independent Data Monitoring Committee (IDMC) will be instituted to ensure external 
objective medical and/or statistical review of efficacy and safety in order to protect the 
ethical interests and well-being of subjects and to protect the scientific validity of this 
study.  
The IDMC will evaluate accumulating efficacy, tolerability, safety and PK of CAB LA + 
RPV LA Q8W at predetermined times during the study.  An interim futility analysis will 
be performed for the IDMC to evaluate the efficacy of CAB LA + RPV LA Q8W prior to 
the final analysis.  Full details of the methods, timing, decision criteria, and operating 
characteristics will be pre-specified in the IDMC Charter. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
64 
 
The interim futility analysis will be performed with the intent of having approximately 
50% of participants reaching Week 24 and providing sufficient lead time to allow the 
IDMC to review the data prior to any participants reaching the Week 52 visit.  A futility 
rule based on Bayesian posterior predictive probability approach will be applied to assess 
the probability that the CAB LA + RPV LA Q8W injectable regimen demonstrates non-
inferiority to the CAB LA + RPV LA Q4W regimen, given the partial data set.  The 
sponsor will remain blinded to this analysis. 
In addition, the IDMC may also monitor the incidence of participants meeting Confirmed 
Virologic Failure (CVF) criteria through Week 48 to ensure that participants are not 
being sub-optimally treated in the CAB LA + RPV LA Q8W arm. 
Full details of the analyses, estimated timing, and the decision criteria that will be used to 
determine regimen performance will be pre-specified in the IDMC Charter. 
4.3. 
Type and Number of Participants 
The target population to be enrolled is HIV-1 infected virologically suppressed (HIV-1 
RNA <50 c/mL) patients on stable antiretroviral therapy (ART) including participants 
who have completed at minimum, Week 52, of the 201585 (ATLAS) study. 
It is anticipated that approximately 1020 participants will be enrolled into ATLAS-2M.  
In addition to participants rolled over from the ATLAS study, additional participants on 
SOC treatment will be screened to supplement enrollment such that the study can be 
appropriately powered (See Section 9.1).  A 15% screen failure rate, for additional 
patients randomized from SOC treatment is anticipated.  Participants will be enrolled 
from multiple countries which may include those countries actively participating in the 
ATLAS study including Argentina, Canada, France, Germany, Italy, Mexico, Russia, 
South Africa, South Korea, Spain, Sweden, and the United States.  
Randomization will be stratified by prior CAB + RPV Exposure: 0 weeks, 1-24 weeks, 
>24 weeks.  A goal of this study is to enroll populations who are underrepresented in 
clinical studies, including approximately 25% women.  To provide sufficient data to 
determine whether either gender is correlated with treatment response, sites are expected 
to take into account gender in their screening strategies.  
4.4. 
Scientific Rationale for Study Design 
The design of this study (1:1 randomized, open-label, active-controlled, multicenter, 
parallel group, non-inferiority study) is well established for confirming the non-
inferiority of an investigational agent compared with an active comparator and is 
generally accepted by regulatory authorities as rigorous proof of antiviral activity. The 
primary endpoint, proportion of participants defined as virologic failures by the FDA 
Snapshot algorithm is recommended in the FDA’s 2015 guidance document (FDA, 2015) 
for assessing efficacy in Switch Trials.  The key secondary endpoints, proportion with 
plasma HIV-1 RNA <50 c/mL at Week 48,Week 96, and Week 152, is also a well-
established surrogate endpoint for prognosis of HIV-1 infection and disease progression. 
The Extension Phase will allow for a collection of longer term efficacy, safety and 
tolerability data for CAB LA + RPV LA Q4W and Q8W regimens.

Various approaches to simplify a patient's antiretroviral therapy (ART) regimen, after 
achieving viral suppression, have been studied.  Previous studies have evaluated switches 
to ritonavir-boosted PI monotherapy therapy in virologically suppressed patients 
[Bierman, 2009 and Arribas, 2012].  While the data from these studies have shown both 
long-term non-inferiority and inferiority to continual Highly Active Antiretroviral 
Therapy (HAART), they suggest that simplifying from a three drug dual class regimen to 
a single boosted protease inhibitor may be a safe and effective option for the majority of 
participants studied who have effectively maintained viral suppression.  
The 200056 (LATTE-2) (GlaxoSmithKline Document Number 2013N168152_05) 
clinical trial evaluated a different simplification approach and served as proof of concept 
for ATLAS-2M.  In 200056, HIV-1 RNA suppression was induced with a three drug 
antiretroviral regimen consisting of CAB + ABC/3TC FDC, and then participants 
switched to a two-drug two-class regimen consisting of CAB LA + RPV LA for the 
maintenance of HIV-1 RNA suppression.  Results demonstrate that through 96 weeks on 
two-drug maintenance therapy, 94% (Q8W IM arm) and 87% (Q4W IM) of subjects 
maintained virologic suppression (HIV-1 RNA <50 c/mL) compared to 84% of subjects 
continuing oral CAB + 2 NRTIs. CAB LA + RPV LA was well tolerated through 
Week 96 for both the Q8W and Q4W dosing regimens, as demonstrated by a low 
discontinuation rate due to AEs, including injection site reaction (ISR) related AEs in 
either dosing arm, with no significant dose-dependent trends in safety parameters.  On the 
basis of 200056 Week 48, and Week 96 data, Q4W and Q8W IM dosing have been 
progressed into Phase 3 for further clinical development, respectively.  The CAB LA + 
RPV LA Q4W regimen is currently under evaluation in the ongoing Phase 3 201584 and 
201585 studies.  
The open-label design best suits the objectives of this study.  A double-dummy design 
could not be undertaken given the logistical challenges of blinding each regimen.  
Because 2 injections of each investigational product are administered at every visit, a 
double-dummy design would require all subjects to chronically receive 4 injections per 
Q4W visit (2 active and 2 placebo), which could be intolerable for patients. In addition, 
the volume of CAB LA and RPV LA injections will differ significantly between Q8W 
and Q4W IM injections (3 mL vs 2 mL each), it would not be logistically feasible to 
blind site staff nor patients from the study treatments being administered.  
Participants randomized to receive CAB LA + RPV LA Q8W IM administration will be 
required to participate in clinic visits approximately every 8 weeks while participants 
randomized to receive Q4W IM administration will be required approximately monthly 
clinical visits. Importantly, secondary objectives of this study are to understand the 
acceptability, tolerability, and patient reported preferences to these novel injectable 
regimens.  An unblinded study design supports collection of participant preference data 
in a way that would not be possible if a double-blind, double-dummy design were 
implemented. If the Q8W arm were required to receive blinded placebo injections every 
month, the value of comparing safety, tolerability, and convenience of Q8W compared to 
Q4W administrations would be limited and include overly burdensome visit requirements 
for those randomized to Q8W administration.  Additionally, the perceived value for 
participants to transition from the ATLAS study to ATLAS-2M for potential 
randomization to the Q8W regimen would also be limited and may result in loss of 

TMF-13901227

207966 
 
66 
 
patients with prior Q4W experience, thereby limiting the ability to compare experience of 
Q4W and Q8W regimens within individual patients.   
Due to the complexities, lack of feasibility and limitations of blinding CAB LA and RPV 
LA injections for Q8W compared to Q4W administration, this Phase 3b study is planned 
as open label.   
To maintain the integrity of the trial, data aggregated by actual treatment group will not 
be made available to members of the Study Team in advance of the first planned sponsor 
analysis when all subjects have completed Week 24 (see Section 9.2.3.1) and will not be 
shared with Investigators until the primary analysis at Week 48.  In addition, central 
randomization will be used to ensure that selection bias is avoided (see Section 6.2).  
Lastly, ascertainment bias affecting the primary efficacy analysis is unlikely since the 
primary endpoint is inherently objective, being primarily determined by HIV-1 RNA 
laboratory assessment. The open label design should therefore have no impact on the 
analysis of study endpoints.

Dose Justification 
4.5.1. 
Oral Lead-In Phase 
Participants entering the study from oral SOC will receive oral CAB 30 mg + RPV 25 mg 
once daily during the 4-week oral lead-in phase to confirm tolerability prior to receiving 
CAB LA + RPV LA injectable treatment.  Data from study LAI116181 
[GlaxoSmithKline Document Number 2011N130484_00] have demonstrated that there is 
no clinically relevant drug-drug interaction following repeat oral administration of CAB 
with RPV.  Oral RPV 25 mg once daily, the approved oral dose of RPV, has been 
administered in combination  with oral CAB to HIV-infected participants in Phase 2b 
studies LAI116482 [(LATTE); GlaxoSmithKline Document Number 2014N216014_00] 
(CAB 10, 30, or 60 mg once daily) and 200056 [LATTE-2] (CAB 30 mg, oral lead-in 
phase).  The CAB 30mg oral dose was selected based on observed safety and efficacy 
from the LATTE-2 study for use during the oral lead phase of Phase 3 studies 201585

LA.  The present study will also use CAB 30 mg once daily with RPV 25 mg once daily 
during the oral lead-in phase.    
CAB demonstrated good short-term safety/tolerability and antiviral activity as 
monotherapy following oral administration of 5 mg and 30 mg once daily.  LAI116482 
(LATTE)  Phase IIb, dose-ranging study (randomized 1:1:1: to CAB 10 mg, 30 mg, or 60 
mg) evaluating the long-term efficacy and safety of a two-drug, two-class, once daily 
combination of CAB + RPV in HIV-infected, treatment-naïve adult participants.  
Following a 24-week phase of induction of virologic suppression using CAB + 2 NRTIs, 
the regimen was simplified to oral CAB + RPV once daily at Week 24 and continued for 
an additional 72-weeks (total comparative study duration of 96 weeks; Margolis, 2015).  
The results of this study also informed the Phase IIb study 200056 (LATTE-2) with 
intramuscular CAB LA and RPV LA.   
Comparable efficacy, safety, and tolerability were observed across all three CAB doses at 
the early dose selection and confirmation visits at Week 16 and 24 in LATTE.  The

proportion of participants who achieved the primary endpoint of HIV-1 RNA <50 c/mL 
(Missing, Switch, Discontinuation=Failure [MSDF] algorithm) at Week 48 (24 weeks on 
Maintenance) remained consistently high across the CAB dose arms (≥80%) with a low 
rate of confirmed virologic failure (Table 2).  Across all dose arms, CAB achieved 
similar efficacy at Week 24 of Induction when co-administered with 2 NRTIs and at 
Week 96 when co-administered with RPV 25 mg once daily (72 weeks on Maintenance).  
Rates of virologic suppression through Week 96 (Maintenance) on the two-drug regimen 
remained similar to that attained through Week 24 (Induction) on three-drug ART.

CAB was administered with 2 NRTIs through Week 24 (Induction Phase) of LATTE. 
95% CIs are normal approximation confidence intervals.   
 
CAB was well tolerated across all doses studied and none of the doses met pre-defined 
safety stopping criteria.  A good safety and tolerability profile with a low discontinuation 
rate due to AEs was observed in all three dose arms with no significant dose-dependent 
trends in safety parameters.   
Although CAB 30 mg was already selected based on short-term efficacy and safety 
through Week 24, the observed durability of viral suppression through 96 weeks across 
all doses, provided further support for CAB 30 mg dose selection in Phase 3 and the

present study.  In addition, the 30 mg dose achieves CAB plasma trough concentrations 
that are greater than mean CAB plasma concentrations observed following CAB LA 
dosing which allows an adequate assessment of safety and tolerability prior to 
transitioning to the long-acting, Maintenance Phase of the study (Table 3). 
CAB has low risk of causing or being a victim of drug-drug interactions, and therefore, 
the selected 30 mg dose can be safely used with most common concomitant medications 
without dose adjustment.  CAB exposures are not impacted by the presence of food; 
however, given that it will be co-administered with RPV which requires food for optimal 
absorption, the recommended intake of oral CAB in the Phase 3 studies is with food at 
the same time as RPV.   
Overall, the efficacy and safety data from the LATTE study, CAB exposure following 
LA administration, and limited drug-drug interaction potential, support selection of the 
CAB 30 mg dose for once daily administration with the approved dose of RPV 25 mg 
once daily during the oral lead-in phase of this study.

Long Acting Injectable for Maintenance Phase 
The safety and efficacy of a 2-drug regimen with CAB and RPV for maintenance of 
virologic suppression was established in LATTE, as detailed in Section 4.5.1, and 
informed the Phase 2b study (LATTE-2) with CAB LA and RPV LA.  Study 200056 
(LATTE-2) is an ongoing, Phase 2b dose-ranging study evaluating the long-term efficacy 
and safety of a two-drug, two-class combination of CAB LA + RPV LA given every 
4 weeks (Q4W) or every 8 weeks (Q8W), as compared to an oral three-drug regimen, for

maintenance of virologic suppression in HIV-infected, treatment-naive adults.  The first 
phase of the LATTE-2 study was a 20-week Induction Phase (16 weeks of oral CAB + 2 
NRTIs, 4 weeks of CAB + 2 NRTIs + oral RPV).  Participants who were eligible to 
continue into the Maintenance Phase were then randomized (2:2:1) to receive IM 
injections of CAB LA every 4 weeks (800 mg Day 1 then 400 mg Q4W) or every 8 
weeks (800 mg Day 1, 600 mg Week 4, 600 mg Week 8, then 600 mg Q8W) in 
combination with IM RPV LA every 4 weeks (600 mg Day 1 then 600 mg Q4W) or 
every 8 weeks (900 mg Day 1, 900 mg Week 8, then 900 mg Q8W), respectively, or to 
continue on their triple ART regimen.  
The Q4W dosing strategy was selected for further investigation in Phase 3 based on 
observed efficacy, safety, and tolerability at Week 48.  Both Q4W and Q8W regimens 
were continued throughout the Maintenance Phase as planned, and Week 96 results 
(Table 4) were supportive of further evaluation of the Q8W regimen in the present study.  
Moreover, LATTE-2 was amended to permit subjects to remain on their randomized LA 
regimen (either Q4W or Q8W) during the Extension Phase (post Week 96), and those 
subjects randomized to the oral comparator arm were allowedtransition to either LA 
regimen at Week 96.  Forty-four subjects were transitioned from the oral comparator arm 
to LA treatments in the Extension Phase; 34 (77%) opted for the Q8W regimen and 10 
(23%) for the Q4W regimen.  Initial LA injections were administered at Week 100 
following a 4-week oral lead-in where 2 NRTIs were discontinued and RPV 25 mg once 
daily was added to CAB 30 mg once daily.

Modeling and simulation was used to enable simplification and alignment of loading dose 
strategy used in LATTE-2 for both Q4W and Q8W CAB LA and RPV LA dosing 
regimens, resulting in selection of optimized Q4W and Q8W LA dosing regimens for use 
in Phase 3 studies (Q4W) and the present study (Q4W and Q8W) as discussed in Section

4.5.2.1. 
CAB LA Q8W 
The CAB LA 600mg Q8W regimen is predicted to achieve concentrations above 
1.35 g/mL, the geometric mean C following oral CAB 10 mg once daily which was 
shown to be efficacious in the LATTE study.  The lower bound of the 90% prediction 
interval is approximately 0.166 g/mL, indicating that 95% of subjects on this regimen 
should remain above the PA-IC90 throughout dosing (Figure 4).  The CAB LA Q8W 
regimen consists of identical 600 mg doses administered at Day 1, Week 4, and Q8W 
thereafter.

Therefore, Day 1 (time zero) = date of first injections in 207966 
4.5.2.1.1. CAB PK Profile Following Transition to Q8W Regimen 
There are two ways in which study participants may transition to the Q8W regimen, 
either directly from oral SOC or directly from Q4W dosing from ATLAS.  Figure 4 
shows the predicted plasma CAB PK profile for SOC participants directly transitioning to 
Q8W dosing following completion of the oral lead-in phase.  The majority of participants 
receiving Q4W injections will have received injections for more than 1 year and will 
have achieved steady-state CAB concentrations within ATLAS well before transitioning 
to Q8W dosing in ATLAS-2M.  Figure 5 shows the predicted plasma CAB PK profile for

participants directly transitioning to Q8W dosing from Q4W dosing who have achieved 
steady-state plasma CAB concentrations.  Other participants, however, may have only 
received a short course of Q4W injections in ATLAS and will have not yet achieved 
steady-state plasma CAB concentrations prior to transitioning to Q8W dosing.  Figure 6 
shows the predicted plasma CAB PK profile for participants directly transitioning to 
Q8W dosing from a short course of Q4W dosing who have not achieved steady-state 
plasma CAB concentrations.

Figure 7 simultaneously shows the median predicted plasma CAB PK profile following 
transition to Q8W dosing from oral SOC, a short course of Q4W, or long-term Q4W 
dosing.  Regardless of route of transition (oral or IM) or prior length of IM dosing (short 
course or steady-state), plasma CAB concentrations are predicted to be safe and 
efficacious during the transition period and all participants are expected to achieve 
comparable target concentrations at Week 48.  In addition, Figure 7 demonstrates that 
participants transitioning from Q4W dosing (regardless of short course or long-term 
Q4W dosing), do not require an intermediate dose at Week 4 as plasma CAB 
concentrations are above Q8W targets and thus can commence Q8W dosing starting from 
the first Q8W dose at Day 1.

A one-week delay in CAB LA dosing for the Q8W regimen at steady state is predicted to 
result in ~92% rather than 95% of subjects achieving trough concentrations above the 
PA-IC90, which is considered acceptable. 
4.5.2.2. 
CAB LA Q4W 
There are two ways in which study participants may transition to the Q4W regimen, 
either directly from oral SOC or directly from Q4W dosing from ATLAS.  Figure 8 
shows the predicted plasma CAB PK profile for SOC participants directly transitioning to 
Q4W dosing following completion of the oral lead-in phase.  Former ATLAS participants 
receiving Q4W injections and randomized to the Q4W dosing arm of ATLAS-2M will 
continue receiving Q4W injections as scheduled. 
The CAB LA 400 mg Q4W regimen is predicted to achieve trough concentrations above 
4x PA-IC90 in 98% of participants at steady-state and 88% is predicted to achieve trough 
concentrations above the geometric mean trough following the 10 mg oral dose in 
LATTE of 1.35 g/mL (8x PA-IC90).  The lower bound of the PI remains approximately 
at or above 4x PA-IC90 throughout dosing (Figure 8).  The CAB LA Q4W regimen 

TMF-13901227

207966

consists of a 600 mg loading dose on Day 1 followed by a 400 mg maintenance dose at 
Week 4 and Q4W thereafter.

Medium dashed line at 1.35 g/mL corresponds to the geometric mean Ctrough concentration following

Dotted line at 0.664 g/mL corresponds to 4x PA-IC90  
Long dashed line at 0.166 g/mL corresponds to the PA-IC90. 
 
At steady state, a one-week delay in dosing of the Q4W regimen results in approximately 
15% reduction in median CAB trough.  With this delay, 95% are predicted to remain 
above 4x PA-IC90, and 79% are predicted to remain above the 10 mg oral trough 
concentrations.  Therefore, a 1-week delay is the maximum allowed per the protocol.

RPV LA Q8W 
The RPV LA Q8W regimen for this study (ATLAS-2M) was selected based on safety 
and efficacy data from study 200056 (LATTE-2) and supported by modeling and 
simulation of pharmacokinetic data obtained following administration RPV LA 
administration in healthy subjects (Phase 1 studies C158, and LAI115428 
[GlaxoSmithKline Document Number 2011N112455_03]) and in HIV-infected subjects 
(Phase 2 study LATTE-2), the majority of the data coming from 200056 (LATTE-2).

The RPV LA 900 mg Q8W regimen is predicted to achieve median (90% PI) steady-state 
C of 54 ng/mL (23 – 112 ng/mL) (Figure 10).  With this regimen, 100% of subjects 
remain above the RPV PA-IC90 during the whole dose interval at steady-state.  These 
data are similar to the observed Week 32 median steady-state C in LATTE-2 for Q8W 
which was also 54 ng/mL and the mean C was 58 ng/mL.  The RPV LA Q8W regimen 
consists of identical 900 mg doses administered at Day 1, Week 4, and Q8W thereafter.  
With the second RPV LA dose administered 4 weeks after the first dose, the anticipated 
median RPV C at Week 4 (prior to second injection) is 40 ng/mL (versus 30 ng/mL 
observed prior to second injection at Week 8 in LATTE-2, where the RPV LA dose at 
Week 4 was not included), with >92% of subjects above the RPV PA-IC90 of 12 ng/mL.

Therefore, Day 1 = date of first injections for Study 207966 
4.5.3.1.1. RPV PK Profile Following Transition to Q8W Regimen 
As previously described, there are two ways in which study participants may transition to 
the Q8W regimen, either directly from oral SOC or directly from Q4W dosing from 
ATLAS.  Figure 10 shows the predicted plasma RPV PK profile for SOC participants 
directly transitioning to Q8W dosing following completion of the oral lead-in phase.

Participants may also transition to RPV LA Q8W in ATLAS-2M following RPV LA 
Q4W, treatment for a minimum of 52 weeks in ATLAS or following a shorter duration of 
RPV LA Q4W treatment following transition from oral SOC after Week 52 in ATLAS.  
Figure 11 shows the predicted plasma RPV PK profile for participants directly 
transitioning to Q8W dosing from Q4W dosing who have achieved steady-state plasma 
RPV concentrations.   
Figure 11 
Simulated Median (90% PI) RPV Profile following Steady State RPV 
LA Q4W Administration in ATLAS prior to Transitioning to Q8W on 
Day 1 of ATLAS-2M 
 
Figure 12 shows the predicted median (90% PI) profile for subjects switching to RPV LA 
Q8W after having a short course of 4 RPV LA Q4W injections.  In this setting, switching 
immediately to RPV LA 900 mg 8-weekly injections keeps the median C above 2x the 
RPV PA-IC90 and 100% of subjects remain above the RPV PA-IC90 during the whole 
dose interval. Figure 13 shows that (until steady-state is reached), the median predicted 
C for those transitioning from Q4W to Q8W is higher than the predicted C for those 
transitioning from oral to Q8W, despite not having the extra RPV LA 900 mg IM 
injection 4 weeks after the first injection on the Q8W regimen.  This therefore justifies

CONFIDENTIAL 
 
 
 
207966 
 
82 
 
the simplified RPV LA dosing regimen (without injection at Week 4) for those subjects 
that are already on a Q4W regimen. 
Therefore, regardless of the length of time that they are already on RPV LA Q4W 
treatment, such subjects transitioning to RPV LA Q8W will receive RPV LA 900 mg IM 
Q8W from Day 1 of ATLAS-2M.

At steady-state, a one-week delay in dosing for the Q8W regimen is predicted to result in 
a median steady-state C that is approximately 11% lower (48 ng/mL) than for dosing 
that is administered on schedule, with >99% of subjects still remaining above the RPV 
PA-IC90.  This supports allowance of some flexibility in the dosing regimen in ATLAS-
2M, similar to what is currently practiced in the LATTE-2 study. 
4.5.3.2. 
RPV LA Q4W 
The RPV LA Q4W regimen for ATLAS-2M was selected based on LATTE-2 safety and 
efficacy data as described above and supported by modeling and simulation of 
pharmacokinetic data as described above.  The Q4W dose regimen consists of a RPV LA 
900 mg dose on Day 1, and RPV LA 600 mg every 4 weeks thereafter.  This regimen is 
also studied in the Phase 3 studies ATLAS and FLAIR.  
There are two ways in which study participants may transition to the Q4W regimen, 
either directly from oral SOC or directly from Q4W dosing from ATLAS.  Figure 14 
shows the predicted plasma RPV PK profile for SOC participants directly transitioning to 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
84 
 
Q4W dosing following completion of the oral lead-in phase.  Former ATLAS participants 
receiving Q4W injections and randomized to the Q4W dosing arm of ATLAS-2M will 
continue receiving Q4W injections as scheduled. 
The predicted median (90% PI) steady-state C for the proposed regimen is 84 ng/mL 
(41 – 161 ng/mL, Figure 14).  With this regimen, >99% of participants remain above the 
5th percentile of steady state trough values following oral RPV 25 mg (corresponding to 
2x the PA-IC90).  With a loading dose of 900 mg RPV LA on Day 1, the anticipated 
median RPV C at Week 4 is 40 ng/mL, with >92% of participants above the RPV PA-
IC90.

^Study Time and Events include a 4-week oral lead in.  Therefore, Day 1 = day of first injections for Study 207966  
 
At steady-state, a one-week delay in dosing for the Q4W regimen is predicted to result in 
a median steady-state C that remains above the median trough for oral RPV 25 mg once 
daily.  This supports allowance of some flexibility in the dosing regimen, as also 
practiced in LATTE-2 and the Phase 3 studies FLAIR and ATLAS.

SELECTION OF STUDY POPULATION AND 
WITHDRAWAL CRITERIA 
Specific information regarding warnings, precautions, contraindications, adverse events, 
and other pertinent information on the investigational regimen or other study treatment 
that may impact participant eligibility is provided in the current Investigator’s Brochures 
(IB) for CAB and RPV and Edurant product label. 
Deviations from inclusion and exclusion criteria are not allowed because they can 
potentially jeopardize the scientific integrity of the study, regulatory acceptability or 
participant safety.  Therefore, adherence to the criteria as specified in the protocol is 
essential. 
5.1. 
Inclusion Criteria 
A participant will be eligible for inclusion in this study only if all of the following criteria 
apply: 
• 
Be able to understand and comply with protocol requirements, instructions, and 
restrictions; 
• 
Understand the long term commitment to the study and be likely to complete the 
study as planned; 
• 
Be considered appropriate candidates for participation in an investigative clinical 
trial with oral and intramuscularly injectable medications (e.g., no active substance 
use disorder, acute major organ disease, or planned long-term work assignments out 
of the country, etc.).   
The following are study specific eligibility criteria unless stated otherwise.  In addition 
to these criteria, Investigators must exercise clinical discretion regarding selection of 
appropriate study participants, taking into consideration any local treatment 
practices or guidelines and good clinical practice (GCP).  All participants must be 
considered appropriate candidates for antiretroviral therapy in accordance with 
local treatment guidelines. 
Laboratory results from the central laboratory services provided by this trial will be used 
to assess eligibility.  In exceptional circumstances only, if a repeat lab is required because 
a central lab result cannot be generated, local labs can be reviewed and approved by the 
Medical Monitor for consideration of participant eligibility.  A repeat central lab will be 
submitted concurrently or at the next planned visit. 
Source documentation to verify entry criteria must be reviewed by the Principal 
Investigator or designee prior to randomization.  Source documents from other medical 
facilities must be located/received during the 14-day screening phase (or up to 35 days) 
and under no circumstances may the participant be randomized in the absence of source 
documentation.  
All Participants eligible for enrolment in the study must meet all of the following 
criteria:

questionable cases a blood sample with simultaneous follicle stimulating 
hormone (FSH) and estradiol levels consistent with menopause (refer to 
laboratory reference ranges for confirmatory levels)].  Females on 
hormone replacement therapy (HRT) and whose menopausal status is in 
doubt will be required to use one of the highly effective contraception 
methods if they wish to continue their HRT during the study.  Otherwise, 
they must discontinue HRT to allow confirmation of post-menopausal 
status prior to study enrolment.  
b. Reproductive potential and agrees to follow one of the options listed in the 
Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of 
Reproductive Potential (FRP) from 30 days prior to the first dose of study 
medication, throughout the study, for at least 30 days after discontinuation of all 
oral study medications, and for at least 52 weeks after discontinuation of CAB LA

security category.   
Participants receiving oral standard of care (SOC) treatment for HIV-1 (not 
participating in ATLAS Trial) 
5. Must be on uninterrupted current regimen (either the initial or second ARV 
regimen) for at least 6 months prior to Screening.  Any prior switch, defined as a 
change of a single drug or multiple drugs simultaneously, must have occurred due 
to tolerability/safety, access to medications, or convenience/simplification, and 
must NOT have been done for treatment failure (HIV-1 RNA ≥400 c/mL).  
Acceptable stable (initial or second) ARV regimens prior to Screening include 2 
NRTIs plus:

cART regimen or one historical within class switch is permitted due to 
safety/tolerability) 
 
The addition, removal, or switch of a drug(s) that has been used to treat HIV 
based on antiretroviral properties of the drug constitutes a change in ART with the 
following limited exceptions:  
 
• Historical changes in formulations of ART drugs or booster drugs will not 
constitute a change in ART regimen if the data support similar exposures 
and efficacy, and the change must have been at least 3 months prior to 
Screening. 
 
• Historical perinatal use of an NRTI when given in addition to an ongoing 
HAART will not be considered a change in ART regimen. 
 
• A change in dosing scheme of the same drug from twice daily to once 
daily will not be considered a change in ART regimen if data support 
similar exposures and efficacy.   
 
6. Documented evidence of at least two plasma HIV-1 RNA measurements 
<50 c/mL in the 12 months prior to Screening: one within the 6 to 12-month 
window, and one within 6 months prior to Screening;

protocol dosing requirements and until Day 1 of the ATLAS-2M study.  Any 
disruptions in dosing during ATLAS must be discussed with the Medical Monitor 
for a final determination of eligibility. 
9. Plasma HIV-1 RNA <50 c/mL at Screening 
 
All participants participating in the study should be counseled on safer sexual practices 
including the use and benefit/risk of effective barrier methods (e.g., male condom) and on 
the risk of HIV transmission to an uninfected partner. 
5.2. 
Exclusion Criteria 
Deviations from exclusion criteria are not allowed because they can potentially 
jeopardize the scientific integrity of the study, regulatory acceptability, or participant 
safety.  Therefore, adherence to the criteria as specified in the protocol is essential.  A 
participant will not be eligible for inclusion in this study if any of the following criteria 
apply: 
Exclusionary Criteria prior to Screening or Day 1 for patients not transitioning 
from 201585 (ATLAS)

Medical Monitor and Study virologist for study participation. 
Exclusionary medical conditions- for all participants 
10. Women who are pregnant, breastfeeding or plan to become pregnant or breastfeed 
during the study 
11. Any evidence of a current Center for Disease Control and Prevention (CDC) 
Stage 3 disease [CDC, 2014] , except cutaneous Kaposi’s sarcoma not requiring 
systemic therapy, and CD4+ counts <200 cells/L are not exclusionary. 
12. Participants with moderate to severe hepatic impairment 
13. Any pre-existing physical or mental condition (including substance use disorder) 
which, in the opinion of the Investigator, may interfere with the participant’s 
ability to comply with the dosing schedule and/or protocol evaluations or which 
may compromise the safety of the participant 
14. Participants determined by the Investigator to have a high risk of seizures, 
including participants with an unstable or poorly controlled seizure disorder.  A 
participant with a prior history of seizure may be considered for enrolment if the 
Investigator believes the risk of seizure recurrence is low.  All cases of prior 
seizure history should be discussed with the Medical Monitor prior to enrolment 
15. All participants will be screened for syphilis. Participants with untreated 
secondary (late latent) or tertiary syphilis infection, defined as a positive RPR and 
a positive treponemal test without clear documentation of treatment, are 
excluded. Participants with a false positive RPR (with negative treponemal test) 
or serofast RPR result (persistence of a reactive nontreponemal syphilis test 
despite history of adequate therapy and no evidence of re-exposure) may enroll 
after consultation with the Medical Monitor. Participants with primary syphilis or 
early latent secondary syphilis (acquired within the preceding year) who have a 
positive RPR test and have not been treated may be treated during the screening 
period and if completion of antibiotic treatment occurs during the screening 
period, may be allowed entry after consultation with the Medical Monitor. If 
antibiotic treatment cannot be completed before the screening window ends, 
subjects may be rescreened once following completion of antibiotic therapy for 
primary or early latent secondary syphilis.

Screening for Hepatitis B surface antigen (HBsAg), Hepatitis B core antibody 
(anti-HBc), Hepatitis B surface antibody (anti-HBs) and HBV DNA as follows: 
a. •Participants positive for HBsAg are excluded; 
b. •Participants negative for anti-HBs but positive for anti-HBc (negative 
HBsAg status) and positive for HBV DNA are excluded 
Note: Participants positive for anti-HBc (negative HBsAg status) and positive for 
anti-HBs (past and/or current evidence) are immune to HBV and are not 
excluded. 
19. Asymptomatic individuals with chronic hepatitis C virus (HCV) infection will not 
be excluded, however Investigators must carefully assess if therapy specific for 
HCV infection is required; participants who are anticipated to require HCV 
treatment within 12 months must be excluded.  (HCV treatment on study may be 
permitted post Week 52, following consultation with the medical monitor) 
20. Participants with HCV co-infection will be allowed entry into this study if:  
a. Liver enzymes meet entry criteria 
b. HCV Disease has undergone appropriate work-up, and is not advanced,

INI or NNRTI resistance-associated mutation, except for K103N, (IAS, 2015) by 
any historical resistance test result. 
Note: Prior genotypic resistance testing is not required but if available it 
must be provided to GSK, after screening and before randomization 
according to guidance in the SPM, to provide direct evidence of no pre-
existing exclusionary resistance mutations. You must wait for the study 
virologists to confirm the lack of exclusionary resistance mutations, which 
will be provided before the screening window closes. Details regarding 
baseline or prior resistance data must be noted in the source 
documentation

Additional Eligibility Criteria 
To assess any potential impact on participant eligibility with regard to safety, the 
investigator must refer to the IB and supplements, approved product labels, and/or local 
prescribing information for detailed information regarding warnings, precautions, 
contraindications, AEs, drug interactions, and other significant data pertaining to the 
study drugs. 
Notwithstanding these minimum inclusion and exclusion criteria, investigators must also 
follow country specific guidelines where they exist when making decisions about 
participants who are eligible for study participation.

Participation in other interventional studies or non-interventional studies that require any 
type of assessment outside the local standard of care practices is generally not permitted, 
however for eligible subjects in South Africa only, co-enrolment in the AIDS Clinical 
Trial Group ACTG interventional study (A5392) could be exceptionally permitted after 
review and approval by the Medical Monitor. 
 
5.4. 
Screening/Baseline/Run-in Failures 
Screen failures are defined as participants who consent to participate in the clinical trial 
but are never subsequently randomized.  In order to ensure transparent reporting of screen 
failure participants, meet the Consolidated Standards of Reporting Trials (CONSORT) 
publishing requirements, and respond to queries from Regulatory authorities, a minimal 
set of screen failure information is required including Demography, Screen Failure 
details, Eligibility Criteria, and Serious Adverse Events. 
A single repeat of a procedure / lab parameter is allowed to determine eligibility (unless 
otherwise specified). 
Participants are allowed to re-screen for this study one time.  This will require a new 
participant number. 
5.5. 
Withdrawal/Stopping Criteria 
Participants permanently discontinuing study treatments prior to the Week 100 visit are 
considered to be withdrawn from the study treatments.   
Participants who enter the Extension Phase but permanently discontinue  participation in 
the Extension Phase prior to the CAB LA + RPV LA marketed product is locally 
available are considered withdrawn from the study treatments but are not considered 
withdrawn from the study because they will enter the Long Term Follow-up Phase. 
Participants who enter the Extension Phase but permanently discontinue participation in 
the Extension Phase when the CAB LA + RPV LA marketed product is locally available 
must enter the Long Term Follow-up Phase if they withdraw from the study due to 
safety-related reasons only. 
The participant may withdraw consent and discontinue participation in this study at any 
time at his/her own request. The investigator may also, at his or her discretion, 
discontinue the participant from participating in this study at any time (e.g., safety, 
behavioral or administrative reasons).  Participants may have a temporary interruption to 
their study treatment for management of toxicities. If a participant withdraws from the 
study, he/she may request destruction of any samples taken, and the investigator must 
document this in the site study records. Withdrawn participants will not be replaced.   
All participants who discontinue prematurely from the study, irrespective of arm, will be 
asked for additional information to establish the reason for withdrawal. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

Participants are not obligated to state the reason for withdrawal.  However, the reasons 
for withdrawal, or failure to provide a reason, must be documented by the Investigator on 
the Completion/Withdrawal section of the electronic case report form (eCRF). Every 
effort should be made by the Investigator to follow-up participants who withdraw from 
the study.  
An in-clinic withdrawal visit will also be used to assess participants with ongoing AEs, 
and serious adverse events (SAEs) related & not related to study drug and also any 
laboratory abnormalities that are considered to be AEs or potentially harmful to the 
participant.  The withdrawal visit will be distinct from visits conducted during the LTFU 
Phase. 
After completing withdrawal assessments, all participants who received one or more 
injections of CAB LA+ RPV LA will subsequently enter the LTFU Phase initiating with 
the Month 3 LTFU visit. When CAB LA + RPV LA marketed product is locally 
available, entering the LTFU phase is only required if the subject withdraws due to 
safety-related reasons.  
Withdrawal decision coincides with a planned clinic visit:  
• For any participant who withdraws prematurely from the Maintenance or 
Extension Phase during a planned in-clinic study visit, withdrawal 
assessments and procedures are to be performed (according to the Time 
and Events Table (Section 7.1) instead of the assessments for the active 
planned visit during which the withdrawal decision is made.   
Withdrawal decision occurs between planned clinic visits: 
• In the event that a decision to withdraw a participant occurs between clinic 
visits, participants will be instructed to return for an unscheduled 
withdrawal visit (within 4 weeks of the last Q4W LA injection or within 8 
weeks of the last Q8W LA injection received) during which withdrawal 
assessments according to the Time and Events Table (Section 7.1) will be 
completed.  For participants who received one or more injections of CAB 
LA+ RPV LA withdrawal assessments must occur prior to initiation of 
the next ART regimen.  
If withdrawal coincides with the active planned Week 52,Week 100, or Week 156 (Q4W 
arm) visits, HIV-1 RNA will only be assessed if the last HIV-RNA measurement from 
Week 48,Week 96, or Week 152 was 50 copies per mL (i.e. retest for viral load blip). 
This will ensure that only the Week 48, Week 96. and Week 152 viral load assessments 
or required retest will be counted towards the primary and secondary efficacy endpoint 
windows.  
The in-clinic visit will be recorded as an unscheduled withdrawal visit with the following 
exception. A withdrawal visit and assessments coinciding with the planned Week 100 
visit will be recorded as the Week 100 visit such that the participant can be considered a 
completer, consistent with the definition of study completer in Section 5.6.

Safety data for all participants who receive any amount of study drug, including 
participants who withdraw from the study, will be included in evaluations of safety. 
All data from the Withdrawal visit will be recorded, as they comprise an essential 
evaluation that should be done prior to discharging any participant from the study. 
The following actions must be taken in relation to a participant who fails to attend the 
clinic for a required study visit: 
a. 
The site must attempt to contact the participant and re-schedule the missed visit as 
soon as possible.  
b. The site must counsel the participant on the importance of maintaining the assigned 
visit schedule and ascertain whether or not the participant wishes to and/or should 
continue in the study.  
c. 
In cases where the participant is deemed ‘lost to follow up’, the investigator or 
designee must make every effort to regain contact with the participant (where 
possible, 3 telephone calls and if necessary a certified letter to the participant’s last 
known mailing address or local equivalent methods). These contact attempts should 
be documented in the participant’s medical record.  
d. Should the participant continue to be unreachable, only then will he/she be 
considered to have withdrawn from the study with a primary reason of “Lost to 
Follow-up”.  
A participant may withdraw from study treatment at any time at his/her own request, or 
may be withdrawn at any time at the discretion of the investigator for safety, behavioral 
or administrative reasons. If a participant withdraws from the study, he/she may request 
destruction of any samples taken, and the investigator must document this in the site 
study records. Please refer to Section 11.5 for additional guidance for sample destruction 
request. 
5.5.1. 
Liver Chemistry Stopping Criteria 
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology. 
IP will be stopped if any of the following liver chemistry criteria are met: 
• 
ALT 3xULN and bilirubin 2xULN (>35% direct bilirubin, bilirubin fractionation 
required). 
• 
NOTE: serum bilirubin fractionation should be performed if testing is available.  If 
testing is unavailable, sites should evaluate the presence of detectable urinary 
bilirubin on dipstick, indicating direct bilirubin elevations and suggesting liver 
injury.  If testing is unavailable and a participant meets the criterion of total bilirubin 
2xULN, then the event meets liver stopping criteria. 
• 
ALT 8xULN.

participant until liver chemistries resolve, stabilize, or return to Baseline values as 
described below. 
• 
Make every reasonable attempt to have participants return to clinic within 24 hours 
for repeat liver chemistries, liver event follow-up assessments (see below), and close 
monitoring. 
• 
A specialist or hepatology consultation is recommended. 
• 
Monitor participants twice weekly until liver chemistries (ALT, AST, alkaline 
phosphatase, bilirubin) resolve, stabilize or return to within Baseline values. 
Make every attempt to carry out the liver event follow-up assessments described below:

5.5.1.4. 
General Guidance Restart 
• The definition of ‘restart’ is not always clear cut in medical practice. Restarts 
should be limited to cases in which there is clear evidence that the underlying 
cause of the liver event is not related to study drug.  
• For long acting agents, a restart may actually be continuation of therapy rather 
than a true re-start due to the timeframe between dose administration relative to 
decision making on allowing a restart. 
• If protocol defined stopping criteria for liver chemistry elevations are met (see 
Section 5.5.1), study drug must be stopped. Participants who meet liver chemistry 
stopping criteria should not be retreated with investigational product unless an 
exemption has been approved by the VSLC.  The guideline for Restart approved 
by the VSLC, which is maintained as a separate document must be followed. 
• If the restart is approved by the VSLC in writing, the participant must be provided 
with a clear description of the possible benefits and risks of drug administration, 
including the possibility of recurrent, more severe liver injury or death.  
• Ethics Committee or Institutional Review Board approval of drug restart must be 
obtained, as required. 
• The participant must also provide signed informed consent specifically for the IP 
restart. Documentation of informed consent must be recorded in the study chart. 
• Study drug must be administered at the dose specified by the VSLC. 
• Participants approved by the VSLC for restart of IP must return to the clinic once 
a week for liver chemistry tests for a minimum of one month and thereafter for as 
long as clinically indicated and then laboratory monitoring may resume as per 
protocol. Longer durations of close monitoring may be required for long acting 
IP. 
5.5.1.4.1. Drug Restart  
“Drug restart” can be approved by the VSLC for defined non-drug-induced liver injury 
if no evidence of: 
• 
immunoallergic injury /HLA association with injury 
• 
alcoholic hepatitis 
Study drug must be held while labs and evaluation are completed to assess diagnosis. 
 
If participant meets liver chemistry stopping criteria do not restart the participant with 
study treatment unless: 
 
• ViiV Healthcare Safety and Labelling Committee (VSLC) approval is granted, 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

• Ethics and/or IRB approval is obtained, if required, and 
 
• Separate consent for treatment restart is signed by the participant. 
Refer to Section 11.3 for full guidance. 
 
Background 
• Restarts should be limited to cases in which there is clear evidence that the 
underlying cause of the liver event is not related to study drug.  
• For long-acting agents, a restart may actually be continuation of therapy rather 
than a true re-start due to the timeframe between dose administration relative to 
decision making on allowing a restart. 
• If protocol defined stopping criteria for liver chemistry elevations are met 
(Section 11.3), study drug must be stopped. Subjects who meet liver chemistry 
stopping criteria should not be retreated with investigational product unless an 
exemption has been approved by the VSLC.  The algorithm for restart is 
described in Section 11.3 and summarised in Figure 8. 
• If the restart is approved by the VSLC in writing, the subject must be provided 
with a clear description of the possible benefits and risks of drug administration, 
including the possibility of recurrent, more severe liver injury or death.  
• Ethics Committee or Institutional Review Board approval of drug restart must be 
obtained, as required. 
• The subject must also provide signed informed consent specifically for the IP 
restart. Documentation of informed consent must be recorded in the study chart. 
• Study drug must be administered at the dose specified by the VSLC. 
• Subjects approved by the VSLC for restart of IP must return to the clinic once a 
week for liver chemistry tests for a minimum of one month and thereafter for as 
long as clinically indicated and then laboratory monitoring may resume as per 
protocol. Longer durations of close monitoring may be required for long-acting 
IP. 
Refer to Section 11.3 for full guidance. 
 
5.5.1.4.2. Drug Restart Following Transient Resolving Liver Events Not Related 
to IP 
Approval by the VSLC for drug restart or additional IM administration can be considered 
where:

CONFIDENTIAL 
 
 
 
207966 
 
101 
 
• 
Abnormalities in liver chemistries have a clear underlying cause (e.g., biliary 
obstruction, hypotension, acute viral hepatitis) and liver chemistries have 
significantly improved.  
• 
If definitive non-study drug related diagnosis, restart will be considered once ALT < 
3x ULN (for participants with baseline ALT < 1.5x ULN) or < 3x baseline ALT 
value (for participants with baseline ALT > 1.5x ULN).    
• 
Ethics Committee or Institutional Review Board approval of drug restart must be 
obtained, as required. 
• 
If restart / redosing of drug is approved by the VSLC in writing, the participant must 
be provided with a clear description of the possible benefits and risks of drug 
administration, including the possibility of recurrent, more severe liver injury or 
death. 
• 
The participant must also provide signed informed consent specifically for the 
restart.  Documentation of informed consent must be recorded in the study chart. 
Study drug must be administered at the dose specified by the VSLCParticipants approved 
by the VSLC for restarting or re-dosing IP must return to the clinic once a week for liver 
chemistry tests for a minimum of one month and thereafter for as long as clinically 
indicated and then laboratory monitoring may resume as per protocol.  If protocol defined 
stopping criteria for liver chemistry elevations are met, study drug must be stopped. 
5.5.2. 
QTc Stopping Criteria 
A participant who has a QTc interval >550 msec considered causally related to IP will be 
withdrawn from the study.  The QTc should be based on averaged QTc values of 
triplicate electrocardiograms obtained over a brief (e.g., 5 to 10 minute) recording 
period.   
If an alternative cause of the QT prolongation is determined (e.g., participant receiving 
drug known to cause prolonged QT or TdP), the IP may be restarted (or continued) after 
consultation and agreement with the Medical Monitor. RPV and RPV LA should not be 
administered to patients who are receiving a drug known to be associated with TdP. 
When performing ECGs, the same QT correction formula must be used for each 
individual participant to determine eligibility for, and discontinuation from, the study.  
This formula may not be changed or substituted once the participant has been enrolled. 
For example, if a participant is eligible for the protocol based on QTcB, then QTcB must 
be used for discontinuation of this individual participant as well. 
Once the QT correction formula has been chosen for a participant’s eligibility, the same 
formula must continue to be used for that participant for all QTc data being collected for 
data analysis.  Safety ECGs and other non-protocol specified ECGs are an exception.

Virologic Failure 
Only plasma HIV-1 RNA values determined by the central laboratory will be used to 
assess virologic failure.  
5.5.4. 
Definition of Protocol-Defined Confirmed Virologic Failure 
For the purposes of clinical management in this study, CVF is defined as:  
Rebound as indicated by two consecutive plasma HIV-1 RNA levels 200 c/mL after 
prior suppression to <200 c/mL. 
5.5.5. 
Managing Virologic Failure 
Following study entry, no changes, or intensification of ART will be permitted prior to 
protocol-defined virologic failure, outside of the planned protocol regimens.  Only 
plasma HIV-1 RNA values determined by the central laboratory will be used to assess 
virologic failure.  Baseline plasma HIV-1 RNA is the assessment completed on study 
Day 1.  The definition of confirmed virologic failure does not apply to participants in the 
LTFU Phase.  These participants will be followed for the emergence of viral resistance.  
 
Inadequate adherence is a common cause for virologic failure, and should be explored as 
a first step in the management of study participants (e.g., at the first indication of 
inadequate virologic response or rebound). Upon notification that a participant’s HIV-1 
RNA plasma level qualifies him/her as a suspected virologic failure, the Investigator 
should query the participant regarding intercurrent illness, recent immunization, or 
interruption of oral therapy. 
5.5.5.1. 
HIV-1 RNA Blips 
HIV-1 RNA “blips” are not usually associated with subsequent virologic failure [DHHS, 
2016].  Although the implications of persistent HIV-1 RNA levels between the lower 
level of detection and <200 c/mL are unclear, the risk of emerging resistance is believed 
to be relatively low.   
Participants with transient increases in HIV-1 RNA (‘blips’ HIV-1 RNA <200 c/mL) are 
not considered suspected virologic failures and do not require a change in therapy.   
Participants who have a HIV-1 RNA ≥50 c/mL and <200 c/mL at the key analysis 
timepoints (Week 48, Week 96, and Week 152) must return to the clinic as soon as 
possible (but no later than 4 weeks after the date of the Week 48, 96, or 152 visit, 
respectively) for a repeat HIV-1 RNA test such that the result falls within the same 
analysis window. 
In order to better characterize HIV-1 RNA ‘blips,’ if there is a known reason / 
explanation for the blip (e.g., immunization, allergies, etc.), the study team should be 
notified of the reason and case context.

If the Investigator has concerns regarding persistent low level viremia (HIV-1 RNA 
≥50 c/mL and <200 c/mL), the Medical Monitor should be contacted to discuss 
participant management.  Following discussion with the Medical Monitor, additional 
viral load testing may be performed between visits to determine the appropriate 
participant disposition for the next scheduled visit 
5.5.5.2. 
Suspected Virologic Failure 
Upon notification that a participant’s HIV-1 RNA plasma level meets the definition of 
virologic failure, the Investigator should confirm the definition is met by initiating a 
repeat of the HIV-1 RNA assessment. 
The following guidelines should be followed for scheduling confirmatory HIV-1 RNA 
testing in an effort to avoid false-positive results: 
• 
Confirmatory testing should be scheduled within 2 to 4 weeks following resolution 
of any intercurrent illness, during which time the participant should receive full dose 
of all IP. 
• 
Confirmatory testing should be scheduled at least 4 weeks following any 
immunization, during which time the participant should receive full dose of all IP. 
• 
If therapy is interrupted* due to toxicity management, non-compliance, or other 
reasons, confirmatory testing should be scheduled 2 to 4 weeks following resumption 
of full dose of all IP. 
• 
The participant should have received full dose of IP for at least 2 weeks at the time 
confirmatory plasma HIV-1 RNA testing is done. 
*Note:  treatment interruption guidelines above may not apply for participants on CAB 
LA + RPV LA treatment.  The study team should be contacted to discuss any treatment 
interruptions for participants meeting the definition of virologic failure. 
In addition, the Investigator should query the participant regarding intercurrent illness, 
recent immunization, or interruption of therapy. 
Sites should contact the Medical Monitor to discuss individual participants, 
whenever necessary. 
5.5.5.3. 
Confirmed Virologic Failure 
Participants with confirmed virologic failure (CVF) must be discontinued from study 
treatment.  However, participants who have received at least one dose of CAB LA or 
RPV LA prior to confirming virologic failure will remain in the study on oral HAART in 
the LTFU Phase. 
A plasma sample from the suspected virologic failure visit as well as Day 1 (if baseline 
HIV-1 RNA level 200 c/mL) will be sent for genotypic and phenotypic resistance 
testing and the result made known to the Investigator when available.  A plasma sample 
from the confirmation visit will be obtained for storage.  This sample may be used for 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
104 
 
possible future analyses, e.g., for genotypic and phenotypic analyses of participants who 
experience virologic failure. 
For all participants who meet CVF, baseline and suspected virologic failure plasma 
samples with HIV-1 RNA level 200 c/mL will be analyzed in an attempt to obtain 
genotype/phenotype data on as many samples as possible.  Plasma samples for storage 
will also be obtained at unscheduled visits including confirmation of CVF.  Participants 
may continue to receive study drug at the discretion of the investigator until results of 
resistance testing are available at which time the participant must be discontinued from 
the study. Even if genotype/phenotype data cannot be generated, participant must also be 
discontinued from the study treatment. 
If a participant is prematurely discontinued from the study treatment, the investigator 
must make every effort to perform the Withdrawal Visit evaluations outlined in the Time 
and Events These data will be recorded as they comprise essential evaluations needed to 
be done before discharging any participant from the study. 
5.6. 
Participant and Study Completion 
The investigator is responsible for ensuring that consideration has been given to the post-
study care of the participant’s medical condition.  
Study Completion 
Participants are considered to have completed the study if they remain on therapy (i.e., 
have not permanently discontinued IP) and satisfy one of the following: 
• 
Randomly assigned to either treatment group, completed the randomized 
Maintenance Phase including Week 100 (with or without Week 100 study treatment) 
and did not enter the Extension Phase; 
• 
Randomly assigned to either treatment group, completed the randomized 
Maintenance Phase including Week 100, and entered and completed the Extension 
Phase (defined as remaining on study until commercial supplies of CAB LA + RPV 
LA Q4W or Q8W regimen become locally available or development of CAB LA + 
RPV LA is terminated). 
 
Participants who withdraw from CAB LA + RPV LA and go into the LTFU Phase will be 
considered to have prematurely withdrawn from the study treatment. 
 
Safety Follow Up visit: 
 
In addition to the 52-week Follow-Up phase required for participants who receive one or 
more injections with CAB LA or RPV LA, an in-clinic or telephone Follow-Up visit will 
be conducted as described below  

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
105 
 
1. Where marketed CAB + RPV LA is locally available:  Safety Follow Up Visit 
is required for subjects completing the study, (may or may not be transitioning 
to CAB + RPV LA marketed product). It should be conducted approximately 
2-4 weeks after the last dose of IP to assess HIV associated conditions, AEs, 
Concomitant medications, ISR AEs after the last injection and the plan to 
transition to marketed product. This visit may be conducted by telephone. 
Ensure relevant eCRF forms (including the Conclusion Visit) are updated / 
completed. 
 
2. Where marketed CAB + RPV LA is not yet locally available:  
a. Safety Follow Up Visit should be conducted approximately 2-4 weeks 
after the last dose of IP and may be conducted by telephone. Ensure 
relevant eCRF forms (including the Conclusion Visit) are updated / 
completed.  This visit is only required if the subject: 
i. has ongoing AEs or Lab abnormalities in the last on-study visit  
AND 
ii. is not planning to attend additional study visits after the last IP 
injection (ie. Withdrawal visit, Long Term Follow up  visits) where 
the ongoing AEs/Lab abnormalities can be assessed. 
b. Safety Follow Up Visit is not required if the subject completes 
Withdrawal visit as scheduled and/or is willing to enter Long Term Follow 
Up phase. Note: If the first study visit after the last injection is scheduled 
more than 3 months after the last dose of IP, please consult the MM to 
advise if Safety Follow Up is still required. 
 
6. 
STUDY TREATMENT 
6.1. 
Investigational Product and Other Study Treatment 
The term ‘study treatment’ is used throughout the protocol to describe any combination 
of products received by the participant as per the protocol design.  Study treatment is 
defined as any investigational treatment(s), marketed product(s), placebo, or 
medical device(s) intended to be administered to a study participant according to 
the study protocol. Study treatment may therefore refer to the individual study 
treatments or the combination of those study treatments. 
Investigational product (IP) in this protocol refers to the investigational study drugs Oral 
Cabotegravir, Cabotegravir LA, Oral Rilpivirine and Rilpivirine LA.  These will be 
supplied by GlaxoSmithKline/ViiV Healthcare and Janssen Pharmaceuticals, 
respectively.  
Participants entering the Long-Term Follow-Up Phase will not have their selected 
HAART provided as clinical trial material.  The selected HAART will be recorded on the 
Concomitant Antiretroviral Therapy (ConART) eCRF page.

6.2. 
Treatment Assignment 
Informed consent must be obtained prior to any study procedures, including Screening 
visit activities. Participants will be assigned to study treatment in accordance with the 
randomization schedule. The randomization schedule, including stratification, will be 
generated using the GSK validated randomization software RANDALL NG. The 
randomization schedule is comprised of a series of blocks, with equal treatment 
allocation within each block, which are shared across centers via central randomization. 
Given the open-label study design, central randomization was used to eliminate selection 
bias due to foreknowledge of randomized treatment.  With central randomization, 
knowledge at a site of the randomized treatment group for previous subjects does not 
predict which treatment group will be assigned to the next randomized subject.  
Randomization and study treatment assignment will be facilitated by the interactive 
response technology (IRT) through the central Randomization and Medication Ordering 
System Next Generation (RAMOS NG).  
Following confirmation of fulfillment of study entry criteria, study site personnel will be 
required to register participants using RAMOS NG for assignment of a unique identifier 
(designating the participant’s randomization code and treatment sequence assignment) for 
each participant participating in the study.  A unique treatment number will be assigned 
for each participant participating in the study. Participants will be randomized in a 1:1 
ratio to CAB LA + RPV LA Q4W or to CAB LA + RPV LA Q8W in accordance with 
the computer generated randomization schedule.  
Participants who successfully complete 100 weeks of treatment and have a viral load 
<50 c/ml at Week 96 (or upon retest by Week 100) will be given the opportunity to enter 
the Extension Phase in which they will continue to receive their CAB LA + RPV LA 
regimen.  In addition, RAMOS NG will facilitate the initial supply and subsequent 
resupply of IP to study sites. 
6.3. 
Dosage and Administration 
Participants will be randomly assigned to receive treatment with CAB LA + RPV LA 
either Q4W or Q8W.  Patients transitioning from oral standard of care therapy will 
initiate their randomized treatment regimen with Oral CAB 30 mg + RPV 25 mg once 
daily for 4 to 5 weeks during the Oral Phase, followed by CAB LA + RPV LA IM 
injections initiating at Week 4b.  Patients transitioning from the ATLAS study and on 
CAB LA + RPV LA Q4W treatment will be randomized at Day 1 to either continue Q4W

administration or transition to Q8W administration of CAB LA + RPV LA.  Regardless 
of treatment arm assignment, the investigator should instruct all participants on the 
importance of treatment adherence.  This study has an open-label design.  Dosing is 
outlined in Table 7 Figure 8 below.

6.4. 
Blinding 
This will be an open-label study and therefore no blinding is required. No summaries of 
the study data according to actual randomized treatment groups will be available to 
sponsor staff prior to the planned Week 24 preliminary analysis. The Week 24 results 
will be restricted to only those study team members and GSK/ViiV Healthcare senior 
management who need to be involved in the analysis and interpretation of the results for 
reporting to regulatory authorities. Public presentation of the Week 24 analysis will not 
be done prior to Week 48 analysis complete. 
6.5. 
Packaging and Labeling 
The contents of the label will be in accordance with all applicable regulatory 
requirements. 
6.6. 
Preparation/Handling/Storage/Accountability 
• The investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study treatment received and any discrepancies 
are reported and resolved before use of the study treatment. 
• Only participants enrolled in the study may receive study treatment and only 
authorized site staff may supply or administer study treatment. All study treatments 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
111 
 
must be stored in a secure, environmentally controlled, and monitored (manual or 
automated) area in accordance with the labeled storage conditions with access limited 
to the investigator and authorized site staff. 
• 
In accordance with local regulatory requirements, the investigator, institution, or the 
head of the medical institution (where applicable) is responsible for study treatment 
accountability, reconciliation, and record maintenance (i.e. receipt, reconciliation and 
final disposition records).  The amount of IP dispensed and/or administered to study 
participants, the amount returned by study participants, and the amount received 
from and returned to GSK must be documented. 
• 
Further guidance and information for the final disposition of unused study treatment 
are provided in the Study Reference Manual.  
• 
Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff.  Take adequate precautions to 
avoid direct eye or skin contact and the generation of aerosols or mists. In the case of 
unintentional occupational exposure notify the monitor, Medical Monitor and/or 
GSK study contact. 
• 
A Material Safety Data Sheet (MSDS)/equivalent document describing occupational 
hazards and recommended handling precautions either will be provided to the 
investigator, where this is required by local laws, or is available upon request from 
GSK. 
• 
Product accountability records must be maintained throughout the course of the 
study. 
IP accountability will be evaluated using pill counts of unused IP for patients receiving 
oral treatment (oral CAB, oral RPV).  This assessment will be conducted, when the 
participant completes oral CAB and RPV lead-in treatment in the Maintenance or 
Extension Phase, or any withdrawal that occurs during an oral treatment phase. 
IP accountability for participants receiving CAB LA + RPV LA will be performed at the 
‘vial’ level (e.g., correct number of vials were used for each injection).  There may be a 
small amount of solution remaining in the vial which does not require quantification.  
Used vials may be discarded at the site once accountability is complete. 
Please refer to Appendix 10 in Section 11.10 for study management information during 
the COVID-19 pandemic. 
6.6.1. 
Dosing Considerations for CAB LA + RPV LA 
Vials of CAB LA and RPV LA are each supplied as a suspension and need no further 
dilution or reconstitution.  Since RPV LA requires refrigeration, sites should allow the 
vial to come to approximately room temperature prior to injecting. The vials should be 
gently inverted a few times to re-suspend sediments and allow bubbles to subside, and 
then use a syringe to withdraw the required volume of suspension for IM injection.   
All injections must be given intramuscularly in the gluteus medius.  Sites may use their 
discretion as to where in the gluteus muscle each injection is given according to 
individual participant circumstance.  If possible, injections should be spaced 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
112 
 
approximately 2 cm from one another, from the site of any previous injection or any 
injection site reaction.  The time and location of injection will be captured in the eCRF.   
IM injections should be administered at a 90 degree angle into the gluteus medius muscle 
using a needle of appropriate gauge and length (In most participants, a 1.5” 23 gauge 
needle for CAB LA and a 1.5” 23 gauge needle for RPV LA is recommended).  The 
needle should be long enough to reach the muscle mass and prevent study drug from 
seeping into subcutaneous tissue, but not so long as to involve underlying nerves, blood 
vessels, or bone.  Variable needle lengths and/or needles with different gauge (CAB LA: 
21 to 25 gauge; RPV LA: 21 to 23 gauge) are permitted if needed to accommodate 
individual body types.  Longer needle lengths may be required for participants with 
higher body mass indexes (BMIs, example > 30), to ensure that injections are 
administered intramuscularly as opposed to subcutaneously.  BMI, needle gauge and 
length used will be collected in the eCRF.  Additional details of the injection device used 
by sites for IM administration including, but not limited to functional performance, may 
also be collected within the eCRF. 
At the Week 4b visit, participants transitioning from oral SOC should be dosed with the 
IM regimen within 2 hours of taking the last oral regimen dose where possible.  
Should IM maladministration be suspected at any time (e.g., suspected under or overdose 
or inadvertent IV dosing), the investigator may consider requesting the participant stay 
onsite for approximately 2-3 hours post dose for safety monitoring and notifying the 
Medical Monitor.  An ECG or any other supportive testing may be obtained at the 
discretion of the investigator.  Additionally, a PK sample may be drawn approximately 
2 hours post dosing for future evaluation of CAB and RPV plasma concentrations. 
Additional dosing instructions and considerations can be found in the SPM. 
6.7. 
Compliance with Study Treatment Administration 
When participants are dosed at the site, they will receive study treatment directly from 
the investigator or designee, under medical supervision.  The date and time of each dose 
administered in the clinic will be recorded in the participant’s eCRF.  The dose of study 
treatment and study participant identification will be confirmed at the time of dosing by a 
member of the study site staff other than the person administering the study treatment.  
When participants self-administer oral study treatments at home, compliance with CAB + 
RPV dosing will be assessed through querying the participant during the site visits and 
documented in the source documents and CRF.  IP accountability will be evaluated using 
pill counts of unused IP (CAB and RPV tablets).  This assessment will be conducted each 
time the participant receives a new (refill) supply of oral study medication, completes the 
oral lead-in or any oral bridging phase.  A record of the number of CAB and RPV tablets 
dispensed to and taken by each participant must be maintained and reconciled with study 
treatment and compliance records.  Treatment start and stop dates will also be recorded in 
the eCRF.  
Due to the long acting nature of the CAB LA and RPV LA it will be imperative that the 
participant is compliant with dosing instructions.  As part of the screening and participant 
selection process, it is imperative that Investigators discuss with potential participants the 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
113 
 
long-term commitments for the trial, and the importance of adhering to treatment 
regimens.  Sites are to have plans in place for adherence counselling for both treatment 
arms of the study for the duration of the study including the LTFU Phase.  In addition, 
Investigators must have plans in place to perform visit reminders, utilizing patient 
trackers provided by the study team as needed, and to verify the participant’s contact 
information at each visit.  Investigators should contact patients directly in the event that a 
participant misses any scheduled visit.  
6.8. 
Protocol Permitted Substitutions 
6.8.1. 
Oral Bridging 
In exceptional circumstances, to address pre-planned missed CAB LA + RPV LA dosing 
visits, in consultation with the medical monitor, Investigators may provide daily oral 
CAB 30 mg and RPV 25 mg as a short-term “bridging” strategy for participants who 
have begun CAB LA + RPV LA.  In certain circumstances (e.g., prior to steady state 
dosing and following a >4 week oral bridge) repeating the loading doses of CAB IM and 
RPV IM may be required.  Participants who withdraw during an oral treatment 
period must be initiated on HAART therapy within 24 hours after the last oral 
treatment with CAB + RPV.  Should a participant require “oral bridging”, sites must 
contact the study Medical Monitor for guidance with treatment and dosing strategies prior 
to a missed CAB LA + RPV LA dose.  
Please refer to Appendix 10 in Section 11.10 for study management information during 
the COVID-19 pandemic. 
6.9. 
Interruption of Study Treatment and Visit/Dosing Windows 
IP may be interrupted at the discretion of the Investigator in the event of an AE, 
according to the severity of the AE. 
If one or more antiretroviral medications is held due to toxicity or adverse events, all 
antiretroviral medications must be held to reduce the risk of development of resistance 
taking into account both the length of the planned interruption and the pharmacokinetic 
half-life of each antiretroviral of the regimen, in a way to minimize the risk of 
development of resistance. 
It is important to note that keeping to the participant’s visit schedule is a very 
important component to the study.   
Note: All decisions regarding dose interruption / resumption must be discussed with 
the Medical Monitor in advance. 
6.9.1. 
IM Dosing 
Participants receiving CAB LA and/or RPV LA are anticipated to be at risk for 
development of virologic resistance if ART is interrupted.  The time period during which 
participants are at risk for development of virologic resistance may be determined by the 
period between when drug levels fall below therapeutic values and when they fall below 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
114 
 
levels which exert selective pressure on HIV.  This time period will vary by ART agent 
and is dependent upon effective concentration, inhibitory concentration, and half-life.  
Plasma concentrations of both LA drugs may be measurable for more than one year 
following IM injections. Any interruption in IM dosing should be discussed with the 
Medical Monitor.  Investigators should ensure that the participant initiates alternative 
highly active ART to minimize the risk of developing resistance as concentrations of 
CAB and RPV decline over time. 
IM dosing is expected to occur during the week in which the participant’s projected visit 
falls (as according to the date of the first injection).  The first injections for participants 
from ATLAS on CAB LA + RPV LA Q4W will occur at Day 1.  The first injections for 
participants transitioning from oral SOC are administered at Week 4b (can be performed 
as soon as lab results from Week 4a become available and should be performed where 
possible within 2 weeks of visit 4a), and the second injections are given at Week 8. 
Between the Week 4a and 4b visits, participants must continue daily treatment with oral 
CAB and RPV tablets.   
Since the first injection visit (Day 1 or 4b) will determine the future injection visit 
schedule for participants, planning for the first injection visit date (within allowed visit 
windows) should take into consideration the availability of the participants to adhere to 
future visit windows (planned vacations, business trips, etc.). 
CAB LA + RPV LA dosing for participants transitioning from SOC treatment is as 
follows: 
All injections should be planned as single injections per drug. 
6.9.1.1. 
IM injections every 4 weeks (Q4W): 
Week 4b only - CAB LA 600 mg + RPV LA 900 mg, each given as 1 X 3 mL IM 
injection 
Week 8 and Q4W thereafter - CAB LA 400 mg IM + RPV LA 600 mg IM every 4 weeks 
for 100 weeks, each given as 1 X 2 mL IM injection 
At Week 4b, participants transitioning from SOC will return to the clinic, take the last 
dose of oral CAB 30 mg + RPV 25 mg, and receive the first CAB LA 600 mg + RPV LA 
900 mg injections (within 2 hours of the final oral dose of CAB + RPV).  The first 
injection visit with IM CAB LA + RPV LA at Week 4b can be performed once central 
lab results are available and safety parameters are reviewed from the Week 4a visit.   
The second and third IM injections with CAB LA 400 mg and RPV LA 600 mg will be 
performed at Week 8 and Week 12.  There will be a -7 day dosing window for the second 
and third IM injections such that the second injection occurs within the window of Week 
7 and Week 8 but no later than Week 8 and the third injection occurs within the window 
of Week 11 and Week 12 but no later than Week 12.  Subsequent injections with CAB 
LA 400 mg and RPV LA 600 mg will occur every 4 weeks (7 days) thereafter.  In 
addition, starting after the Week 16 injection, efforts should be made to limit time 
between injection visits to a maximum of 5 weeks.  The Medical Monitor must be

contacted if the length of time between injections exceeds or is projected to exceed 5 
weeks. 
6.9.1.2. 
IM injections every 8 weeks (Q8W): 
Week 4b – CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM 
injection 
Week 8 - CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM injection 
Week 16 and Q8W thereafter - CAB LA 600 mg + RPV LA 900 mg IM, every 8 weeks 
for 100 weeks, each given as 1 X 3 mL IM injection 
At Week 4b, subjects will return to the clinic, take the last dose of their oral (CAB 30 mg 
+ RPV 25 mg), and receive the first CAB LA (600 mg) + RPV LA (900 mg) injections 
(within 2 hours of the final oral dose of CAB + RPV).  The first injection visit with IM 
CAB LA + RPV LA at Week 4b can be performed once central lab results are available 
and safety parameters are reviewed from the Week 4a visit.   
The second loading injection will be administered at Week 8 (CAB LA 600 mg + RPV 
LA 900 mg, with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) occurring 
every 8 weeks thereafter.  The dosing window for the second injection allows 
administration between Week 7 and Week 8, but preferably not later than Week 8.  After 
Week 16, a dosing window (7 days) for injections is allowed, but not preferred. Starting 
at the Week 16 injection, the interval between injection visits should be limited to a 
maximum of 9 weeks.  If the length of time between injections exceeds, or is projected to 
exceed 9 weeks, the Medical Monitor must be contacted to discuss individual subject 
case management 
Participants transitioning from ATLAS and currently receiving CAB LA + RPV LA 
Q4W 
Patient transitioning from the ATLAS study and on CAB LA + RPV LA Q4W treatment 
will be randomized at Day 1 to either continue Q4W administration or transition to Q8W 
administration of CAB LA + RPV LA.  The first injection visit for the ATLAS-2M study 
can be performed once the final central lab results from the ATLAS study are available 
and safety parameters have been reviewed.  For participants who received three or more 
Q4W CAB LA + RPV LA injections within ATLAS, the transition from ATLAS to 
ATLAS-2M Day 1 dosing must occur 4 weeks (7 days) from the final injections 
received in ATLAS.  For those who received less than three Q4W injections within 
ATLAS, this transition to ATLAS-2M Day 1 injections must occur within 4 weeks (-7 
days) from the final ATLAS injections 
Dosing for participants transitioning from CAB LA + RPV LA Q4W in ATLAS is as 
follows:

207966 
 
116 
 
6.9.1.3. 
IM injections every 4 weeks (Q4W) (Q4W from ATLAS Q4W): 
Starting at Day 1, all injections will continue with the maintenance dose of CAB LA 
400 mg and RPV LA 600 mg administered every 4 weeks (7 days).  In addition, efforts 
should be made to limit time between injection visits to a maximum of 5 weeks.  The 
Medical Monitor must be contacted if the length of time between injections exceeds or is 
projected to exceed 5 weeks. 
6.9.1.4. 
IM injections every 8 weeks (Q8W) (Q8W from ATLAS Q4W): 
Participants transitioning from ATLAS and receiving CAB LA + RPV LA Q8W will 
initiate dosing at the Day 1 visit: 
Day 1- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 3 mL IM injection 
Week 8 and Q8W thereafter- CAB LA 600 mg + RPV LA 900 mg IM, each given as 1 X 
3 mL IM injection 
The second injection will be administered at Week 8 (CAB LA 600 mg + RPV LA 
900 mg, with subsequent injections (CAB LA 600 mg + RPV LA 900 mg) every 8 weeks 
thereafter.  The dosing window for the second injection allows administration between 
Week 7 and Week 8, but preferably not later than Week 8.  After Week 16, a dosing 
window (7 days) for injections is allowed, but not preferred. Starting at the Week 16 
injection, the interval between injection visits should be limited to a maximum of 
9 weeks.  If the length of time between injections exceeds, or is projected to exceed 
9 weeks, the Medical Monitor must be contacted to discuss individual subject case 
management. 
Any request for the visit/dosing to occur outside of the allowed window must be 
discussed and agreed with the Medical Monitor prior to dosing.  In the event of a late 
dose, a revised dosing schedule for subsequent dosing may be required and will be 
communicated to the site staff at the time of approval for continued dosing.  Temporary 
switch to oral dosing of CAB and/or RPV may be an option based on individual 
participant circumstance as described in Section 6.8. 
See the SPM for scheduling guidance and further information and examples. 
Note: All decisions regarding dose interruption/ resumption must be discussed with 
the Medical Monitor in advance. 
6.9.2. 
Oral Dosing 
The Week 4a Visit during the Oral Lead-in Phase for participants transitioning from SOC 
is expected to occur 4 weeks (3 days) after to the Day 1 Baseline visit.  However, the 
number of tablets dispensed should be considered when scheduling the next visit. 
Any interruption in therapy (scheduling conflicts, life circumstances, etc.) during any oral 
dosing period that is greater than 7 consecutive days must be discussed with the Medical 
Monitor prior to resumption of therapy.  The Medical Monitor must be contacted upon 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
117 
 
site staff becoming aware of resumption in therapy, if therapy was resumed without prior 
approval. 
Visits for participants in LTFU are expected to occur as projected according to the last 
injection.   
6.10. 
Discontinuation of Study Treatment 
Participants unable to manage drug toxicity or tolerate investigational product (IP, either 
formulations of CAB or RPV) must have IP discontinued.  Any participant receiving at 
least one dose of CAB LA and /or RPV LA who discontinues IP / Withdraw will initiate 
treatment with HAART enter the LTFU Phase for 52 weeks of follow-up (see Section 
4.2.4). 
When the CAB+RPV LA marketed product is locally available participants must enter 
the LTFU Phase if withdrawing for safety related reasons only.  see Section 5.5. 
 
6.11. 
Treatment of Study Treatment Overdose 
For participants receiving Oral CAB, any tablet intake exceeding a total daily dose of    
30 mg will be considered an overdose.  For participants receiving oral RPV, any dose 
exceeding a total daily dose of 25 mg will be considered an overdose.  
For CAB LA and RPV LA, any single dose in excess of the studied doses will be 
considered an overdose. 
Should IM maladministration, specifically overdose or inadvertent IV dosing, be 
suspected at any time, the participant will stay onsite for approximately 2-3 hours post 
dose for safety monitoring and an ECG will be performed at 2 hours post dose.  The 
Medical Monitor will be notified in the event of a suspected maladministration.  
In the event of suspected maladministration, additional PK samples will be drawn at 
2 hours post dosing for evaluation of CAB and RPV concentrations. 
For the purposes of this study, an overdose is not an AE (refer to Section 11.6.1 ) unless 
it is accompanied by a clinical manifestation associated with the overdose.  If the clinical 
manifestation presents with serious criteria, the event is a SAE (see Section 11.6.2). 
If an overdose occurs and is associated with an adverse event requiring action, all study 
medications must be temporarily discontinued until the adverse event resolves.  
The Investigator should use clinical judgement in treating overdose, as ViiV Healthcare 
is unable to recommend specific treatment. 
In the event of an overdose the investigator or treating physician should: 
1. Contact the Medical Monitor immediately 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
118 
 
2. Closely monitor the participant for adverse events (AEs)/serious adverse events 
(SAEs) and laboratory abnormalities until the IP can no longer be detected 
systemically (at least 5 days for oral CAB and oral RPV, and 52 weeks for CAB LA 
and RPV LA 
3. Obtain a plasma sample for pharmacokinetic (PK) analysis if possible within 2 days 
from the date of the last dose of study treatment if requested by the Medical Monitor 
(determined on a case-by-case basis). 
4. Document the quantity of the excess dose as well as the duration of the overdosing in 
the CRF. 
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the Medical Monitor based on the clinical evaluation of the 
participant. 
6.12. 
Treatment after the End of the Study 
The investigator is responsible for ensuring that consideration has been given to the post-
study care of the participant’s medical condition, whether or not GSK is providing 
specific post-study treatment.  Participants who have successfully completed 100 weeks 
of treatment will continue to have access to both CAB LA and RPV LA in the Extension 
Phase through Week 152 and until study treatment is either locally approved and 
commercially available, the participant no longer derives clinical benefit, the participant 
meets a protocol-defined reason for discontinuation or until development of either CAB 
LA or RPV LA is terminated. 
6.13. 
Concomitant Medications and Non-Drug Therapies 
Participants must be advised to notify their Investigator of any current or proposed 
concomitant medication, whether prescribed or over-the-counter, because of the potential 
for interactions between such treatments and the study medications.  Concomitant 
medications (prescription and non-prescription) will be permitted during the course of the 
study at the investigator’s discretion (except for prohibited medications described in 
Section 6.13.2) and should be administered only as medically necessary during the study.  
All concomitant medication, blood products, and vaccines taken during the study will be 
recorded in the eCRF.  The minimum requirement is that the drug name, route, and the 
dates of administration are to be recorded. 
 
Any medication or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) that the participant is receiving at the time of 
enrollment or receives during the study must be recorded along with: 
• 
reason for use 
• 
dates of administration including start and end dates 
• 
dosage information including dose and frequency 
 
The Medical Monitor should be contacted if there are any questions regarding 
concomitant or prior therapy.

6.13.1. 
Permitted Medications and Non-Drug Therapies 
Chemoprophylaxis for HIV-associated conditions is encouraged, if appropriate, at the 
discretion of the participant and their physician.  All concomitant medications, blood 
products, and vaccines taken during the study will be recorded in the eCRF with dates of 
administration. 
Because non-HIV vaccines may cause a temporary increase in the level of plasma HIV-1 
RNA, it is recommended that a vaccine, if necessary, be given during or immediately 
after a scheduled visit after all laboratory tests have been drawn.  This approach will 
minimize the risk of non-specific increases in the level of plasma HIV-1 RNA at the next 
scheduled assessment. 
Other IM injectables (with exceptions below) are permitted but must be administered 
away from the site of IP administration (should be spaced 2 cm or more away from site of 
IP injection). 
Antacid and H2 Antagonist Use: 
Since co-administration of oral CAB and RPV is required in this study, the most 
restrictive dosing requirements must be taken into consideration.   
CAB oral administration only: Antacid products containing divalent cations (e.g., 
aluminium, calcium and magnesium) must be taken at least 2 hours before or at least 4 
hours after CAB. 
Concurrent administration of multivitamins is acceptable. 
RPV oral administration only:  Antacid products must be taken at least 2 hours before 
or at least 4 hours after RPV.  H2-Receptor antagonists (e.g. cimetidine, famotidine, 
nizatidine, ranitidine) may cause significant decreases in RPV plasma concentrations.  
H2-receptor antagonists should only be administered at least 12 hours before or at least 4 
hours after RPV.  RPV should not be co-administered with proton pump inhibitors, such 
as esomeprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole. 
RPV:  Administration of clarithromycin, erythromycin and telithromycin is not 
recommended with RPV due to possible increase in plasma concentration of RPV due to 
CYP3A enzyme inhibition.  Where possible, alternatives such as azithromycin should be 
considered.  Please refer to the local rilpivirine prescribing information for guidance 
regarding other drugs that are prohibited, should be used with caution, require dose 
adjustment, or increased clinical monitoring if taken with rilpivirine. 
Drugs with a known risk of Torsade des Pointes (TdP) should be used with caution when 
on rilpivirine (see SPM for list of drugs associated with TdP). 
6.13.2. 
Prohibited Medications and Non-Drug Therapies 
The following concomitant medications or therapies are not permitted at any time during 
the study: 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
120 
 
• HIV immunotherapeutic vaccines are not permitted at any time during the 
study.  
• Other experimental agents, antiretroviral drugs not otherwise specified in the 
protocol, cytotoxic chemotherapy, or radiation therapy may not be 
administered (see Exclusion Criteria #35-36, Section 5.2).  
• Systemically administered immunomodulators (such as interleukin and 
interferon agents) are prohibited (a list of examples is provided in the SPM).  
This includes topical agents with substantial systemic exposure and systemic 
effects.  Use of topical imiquimod is permitted.   
• Acetaminophen (paracetamol) cannot be used in patients with acute viral 
hepatitis (James, 2009). 
• Chronic use of systemic (oral or parenteral) glucocorticoids must be avoided 
due to their immunosuppressive effect; however, short treatment courses with 
oral prednisone/ prednisolone/methylprednisolone (e.g. adjunctive treatment 
of Pneumocystis pneumonia with ≤ 21 days of tapering prednisone) are 
allowed.  A single dose of systemic dexamethasone is permitted (more than a 
single dose in a treatment course may cause significant decrease in RPV 
plasma concentration and is prohibited). Topical, inhaled or intranasal use of 
glucocorticoids will be allowed.   
• Hepatitis C infection therapy is prohibited during the Maintenance Phase 
before the Week 48 primary endpoint, and interferon-based HCV therapy or 
use of any drugs that have a potential for adverse drug:drug interactions with 
study treatment is prohibited throughout the entire study.  
For information on concurrent therapies and interactions suspected to be relevant to other 
antiretroviral therapy in the regimen, please consult the local prescribing information. 
6.13.2.1. 
Concurrent with CAB and/or RPV 
For participants receiving either formulation of CAB and/or RPV, the following 
medications could significantly decrease the levels of CAB and/or RPV due to enzyme 
induction and therefore must not be administered concurrently:  
• Carbamazepine 
• Oxcarbazepine 
• Phenobarbital  
• Phenytoin 
• Rifabutin 
• Rifampicin / Rifampin 
• Rifapentine 
• St. John’s wort (Hypericum perforatum) 
Concurrent with CAB 
CAB is a potent inhibitor of OAT1 and OAT3 transport in vitro, however, no clinically 
significant interaction risk is expected for most drugs that are substrates of these 
transporters.  Monitoring may be required for drugs with a narrow therapeutic index and 
dependent on OAT1 and OAT3 transport (e.g. methotrexate) with concomitant CAB

administration.  Refer to the current Investigator’s Brochure (Section 4.3.6.1 and Section 
6.4) for additional information.  
Concurrent with RPV 
In addition, participants must discontinue the following (or change to an allowable 
alternative) while receiving treatment with oral RPV: 
• 
proton pump inhibitors, such as esomeprazole, lansoprazole, omeprazole, 
pantoprazole, rabeprazole; 
• 
systemic dexamethasone (more than a single dose) 
If the participant cannot discontinue use or change to an allowable alternative while 
receiving treatment with RPV, the participant should not be randomized into the study. 
6.13.2.2. 
Concurrent with either CAB LA or RPV LA 
In addition, for participants receiving CAB LA and RPV LA, use of anticoagulation 
agents for greater than 14 days is prohibited, with the exception of the use of 
anticoagulation for deep vein thrombosis (DVT) prophylaxis (e.g., postoperative DVT 
prophylaxis) or the use of low dose acetylsalicylic acid (≤325 mg). Systemic 
anticoagulation (including prophylaxis doses) on the day of an IM injection should be 
avoided. 
Note: Any prohibited medications that decrease cabotegravir or rilpivirine concentrations 
should be discontinued for a minimum of four weeks or a minimum of three half-lives 
(whichever is longer) prior to the first dose and any other prohibited medications should 
be discontinued for a minimum of two weeks or a minimum of three half-lives 
(whichever is longer) prior to the first dose. 
6.13.2.3. 
Prohibited Medications for Participants Receiving HAART during the 
Long-Term Follow-Up Phase 
For participants  taking HAART during the Long-Term Follow-Up Phase, refer to local 
prescribing information for details regarding concurrent therapies. 
6.14. 
Medical Devices 
The medical devices to be used in this study are: vial adaptor, syringe and needle. 
Instructions for medical device use are provided in the Study Reference Manual. 
All device deficiencies, (including malfunction, use error and inadequate labelling) shall 
be documented, and reported by the investigator throughout the clinical investigation (see 
Section 11.2) and appropriately managed by the sponsor.

STUDY ASSESSMENTS AND PROCEDURES 
Protocol waivers or exemptions are not allowed with the exception of immediate safety 
concerns. Therefore, adherence to the study design requirements, including those 
specified in the Time and Events Table, are essential and required for study conduct. 
This section lists the procedures and parameters of each planned study assessment.  The 
exact timing of each assessment is listed in the Time and Events Table (Section 7.1). 
The following points must be noted:  
• If assessments are scheduled for the same nominal time, THEN the assessments 
should occur in the following order: 
1. 12-lead ECG 
2. vital signs 
3. blood draws   
Note: The timing of the assessments should allow the blood draw to occur at the 
exact nominal time. 
• The timing and number of planned study assessments, including safety, 
pharmacokinetic, pharmacodynamic/biomarker assessments may be altered 
during the course of the study based on newly available data (e.g., to obtain data 
closer to the time of peak plasma concentrations) to ensure appropriate 
monitoring.  
• The IRB/IEC will be informed of any safety issues that require alteration of the 
safety monitoring scheme or amendment of the Informed Consent Form.  
 
Please refer to Appendix 10 in Section 11.10 for study management information during 
the COVID-19 pandemic. 
7.1. 
Time and Events Table 
Note:  While some assessments included in the Time and Events Table are conducted less 
frequently following the primary endpoint (Week 48), IM injections for participants 
during the Extension Phase will continue to be administered Q4W or Q8W based on 
original study randomization assignment. 
All patients will be randomized at Day 1 to initiate either Q4 weekly or Q8 weekly 
administration of IM CAB LA + RPV LA. Only participants randomized from oral SOC 
treatment will participate in the Day 1 to Week 4 Oral CAB + Oral RPV lead-in 
treatment.

Safety Follow Up Visit (for subjects completing the study, may or may not be transitioning to CAB + RPV LA marketed product) and 
Safety Follow Up Visit (for subjects withdrawing from the study) are required as described in Section 5.6. 
 
a. 
Complete all Screening assessments within 35 days.  Participants may begin the Maintenance Phase as soon as all Screening assessments are complete.  
Participants may be rescreened once and will be assigned a new participant number.   Participants transitioning from the 201585 (ATLAS) study must reach 
ATLAS Week 48 (at minimum) prior to initiating Screening procedures for ATLAS-2M and must reach ATLAS Week 52 (at minimum) prior to 
randomization in ATLAS-2M.  
b. 
Visits Week 4a is part of the CAB + RPV Oral Lead-in period and is required only for participants transitioning from current SOC to CAB LA + RPV LA. 
c. 
Confirmation of eligibility to continue the Maintenance Phase and eligibility to enter the Extension Phase.  
d. 
Collect full routine medical history plus (report at Baseline visit): HIV risk factors (may be collected at a later study visit), cardiovascular risk factors 
(assessments include smoking status and history, family history of cardiac events), recent [
6 months] illicit drug use, intravenous drug use, gastrointestinal 
disease, metabolic, psychiatric, renal, bone, and neurologic disorders. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
129 
 
e. 
Physical exams should be conducted as part of normal routine clinical care.  Medical assessments include any decisions the study staff must make for 
participants management and/or care of participant.   
f. 
Height collected at Baseline Day 1 only. 
g. 
Measure vital signs after about 5 minutes of rest in a semi-supine position. 
h. 
A 12-lead ECG will be performed after resting in a semi-supine position for at least 5 minutes.  ECGs will be performed pre-dose. For participants 
transitioning from ATLAS, the pre-dose Week 48 ECG can also serve as the ATLAS-2M Screening ECG.  ECG pre-dose will be performed in triplicate at 
Day 1.  A 2-hour post-dose ECG will also be performed at Days 1 and Week 48 for participants receiving CAB LA + RPV LA with an allowable window of 
30 minutes. 
i. 
Only SAEs related to study participation or to a concomitantly administered ViiV/GSK product will be collected between obtaining informed consent and 
administration of study drug at Day 1. 
j. 
On Day 1, the eC-SSRS is to be administered prior to randomization.  The eC-SSRS will preferably be completed at the beginning of the visit following 
administration of other PROs required prior to injections.  The eC-SSRS is not required during the Withdrawal visit if withdrawal occurs during the 
Extension Phase. 
k. 
Women of childbearing potential only.  SR=serum, UR=urine.  Pregnancy events will be captured starting at Day 1 following initial exposure to study drug.  
Urine pregnancy test performed at Day 1 prior to administration of study drug, at Week 4b, and at study visits when other blood draws are not required in 
order to limit needle sticks.  Serum pregnancy test can substitute for urine pregnancy test if locally required but must be appropriately timed to confirm 
pregnancy status prior to randomization and first IM administration. Pregnant participants who remain in the study do not need pregnancy testing during the 
study, for the duration of their pregnancy. Pregnant participants remaining in the study have additional assessments required, as described in Appendix 11. 
l. 
Week 48, Week 96, and Week 152 HIV-1 RNA retest (within 4 weeks) for results > 50 c/mL will be captured as unscheduled visit.  Plasma for storage 
samples will be used for possible future analyses. 
m. 
A morning specimen is preferred.  To assess biomarkers: urine albumin/creatinine ratio; urine protein/creatinine ratio; and urine phosphate. Urine phosphate 
results from visit 4a are not required by protocol to inform the safety review at visit 4b prior to receipt of initial CAB LA + RPV LA injections. 
n. 
An overnight fast is preferred; however, a minimum of a 6-hour fast is acceptable. 
o. 
Only collect if the Withdrawal visit occurs at Week 48 Week 96, or Week 152. 
p. 
Whole blood/PBMC collection samples may be used for virologic analyses.  PBMCs will be collected at baseline Day 1, Week 48, Week 96, Week 152 or 
Withdrawal if prior to Week 152. 
q. 
Genetics sample should be collected only for patients who did not participate in the 201585(ATLAS) study (sample was previously collected and stored). 
Informed consent for genetic research must be obtained before sample collection.  Sample may be collected at any visit after signing informed consent, but 
preferably at the Day 1 visit.   
r. 
One blood sample for CAB and RPV each to be collected at each PK timepoint.  At Day 1, for participants from the ATLAS Q4W arm, PK samples are to 
be collected pre-dose relative to IM administration.  At Week 4b, for participants randomized from SOC, Pre dose PK samples are to be collected: AFTER 
review of the PK diary to ensure that the samples are taken 20/28 hours after previous oral dose (diaries to be given at Day 1 or W4a); PRIOR to the final 
oral dose of CAB + RPV; PRIOR to the first IM injection. Trough plasma PK samples of CAB and RPV will be obtained for every pregnant woman at every 
study visit during the pregnancy for both Q4W and Q8W regimens. See Appendix 11. 
s. 
Only for Participants entering CAB + RPV Oral Treatment 
t. 
Participants switching to CAB LA + RPV LA will take final dose of oral lead-in regimen in the clinic at the Week 4b visit and begin injections.  If possible, 
injections should be spaced approximately 2 cm from one another and from the site of any previous injection and or any injection site reaction.  Bring RPV

LA to approximately room temperature prior to injecting.  Time and location of injection (right or left) as well as needle length used will be collected in the 
eCRF. The first injection can be performed as soon as central lab results become available and safety parameters are reviewed.   
u. 
All Patient Report Questionnaires/Surveys will be administered via paper instrument (in exceptional circumstances the questionnaires could be completed 
via telephonic interview, please refer to COVID19 appendix for additional details)  at the beginning of the visit before any other assessments are conducted 
and prior to administration of the eC-CSSRS.  During the Maintenance phase conduct questionnaires/surveys (HAT-QoL, HIV TSQs, HIV TSQc, ACCEPT, 
PIN and Preference) at W48 or upon Withdrawal only if occurring at or prior to Week 48. During the Extension phase conduct questionnaires/surveys (HIV 
TSQs, ACCEPT, “Reason for Oral Bridging and Preference questionnaire ” and PIN) at W152 or upon Withdrawal only if occurring at or prior to Week 152 
v. 
The HIV-TSQc is to be administered to all participants transitioning from ATLAS and new participants transitioning from oral SOC.  For participants 
transitioning from ATLAS, the version of the HIV-TSQc instrument to be administered will be based on the initial randomization arm at ATLAS Day 1.  
w. 
For patients randomized to oral SOC at Day 1 in ATLAS or new patients on SOC, the reasons for willingness to switch ART will be assessed at Day 1.  For 
patients randomized to CAB LA + RPV LA Q4W in ATLAS, the reasons for willingness to continue long-acting ART in ATLAS-2M will be assessed at 
Day 1. 
x. 
During Maintenance phase Preference Questionnaire (injection to injection/oral to injection) will be administered to all participants at W48 or upon WD if at 
or prior to W48. “Reason for Oral Bridging and Preference questionnaire ” questionnaire at Week 152 or upon WD visit if occurred at or before Week 152, 
will be administered only to participants who received oral bridging during the Maintenance and/or Extension Phases. 
y. 
Refer to Section 5.5 of the protocol for additional information on performing withdrawal assessments.  HIV-1 RNA will be collected as Storage sample only 
if withdrawal assessments coincide with Week 52  Week 100 or Week 156 (as per Section 5.5)  
z. 
Participants receiving one or more injections with CAB LA and/or RPV LA will be assessed with clinic visits at months 3, 6, 9 and 12 during the Long-Term 
Follow-Up Phase 
aa. 
After discussion of risk/benefit, a pregnancy specific ICF addendum must be signed by pregnant participants who wish to remain in the study

administration of study drug at Day 1. 
kk. 
On Day 1, the eC-SSRS is to be administered prior to randomization.  The eC-SSRS will preferably be completed at the beginning of the visit following 
administration of other PROs required prior to injections.  The eC-SSRS is not required during the Withdrawal visit if withdrawal occurs during the 
Extension Phase. 
ll. 
Women of childbearing potential only.  SR=serum, UR=urine.  Pregnancy events will be captured starting at Day 1 following initial exposure to study drug.  
Serum pregnancy test can substitute for urine pregnancy test if locally required but must be appropriately timed to confirm pregnancy status prior to 
randomization and first IM administration. Pregnant participants who remain in the study do not need pregnancy testing during the study, for the duration of 
their pregnancy. Pregnant participants remaining in the study have additional assessments required, as described in Appendix 11. 
mm.

One blood sample for CAB and RPV each to be collected at each PK timepoint.  At Day 1, for participant from the ATLAS Q4W arm, PK samples are to be 
collected pre-dose relative to IM administration. injection. At Week 4b, for participants randomized from SOC, Pre dose PK samples are to be collected: 
AFTER review of the PK diary to ensure that the samples are taken 20/28 hours after previous oral dose (diaries to be given at Day 1 or W4a); PRIOR to the 
final oral dose of CAB + RPV; and PRIOR to the first IM injection.  At Week 9 and 41, the PK samples should be collected 3 to 10 days after the Week 8 
and Week 40 visits, respectively. Trough plasma PK samples of CAB and RPV will be obtained for every pregnant woman at every study visit during the 
pregnancy for both Q4W and Q8W regimens. See Appendix 11. 
tt. 
Only for Participants entering CAB + RPV Oral Treatment  
uu. 
Participants switching to CAB LA + RPV LA will take final dose of oral lead-in regimen in the clinic at the Week 4b visit and begin injections.  If possible, 
injections should be spaced approximately 2 cm from one another and from the site of any previous injection and or any injection site reaction.  Bring RPV 
LA to approximately room temperature prior to injecting.  Time and location of injection (right or left) as well as needle length used will be collected in the 
eCRF.  The first injection can be performed as soon as central lab results become available and safety parameters are reviewed.   
vv. 
All Patient Report Questionnaires/Surveys will be administered via paper instrument at the beginning of the visit before any other assessments are conducted 
and prior to administration of the eC-CSSRS (in exceptional circumstances, the questionnaires could be completed via telephonic interview, please refer to 
COVID19 appendix for additional details)  . During the Maintenance phase, conduct questionnaires/surveys (HAT-QoL, HIV TSQs, HIV TSQc, ACCEPT, 
PIN, and Preference) at W48 or upon Withdrawal only if occurring at or prior to Week 48. During the Extension phase, conduct questionnaires/surveys (HIV 
TSQs, ACCEPT, “Preference and Reason for OB” and PIN) at W152 or upon Withdrawal only if occurring at or prior to Week 152 
ww. 
The HIVTSQc is to be administered to all participants transitioning from ATLAS and new participants transitioning from oral SOC. For participants 
transitioning from ATLAS, the version of the HIV-TSQc instrument to be administered will be based on the initial randomization arm at ATLAS Day 1 
xx. 
For patients randomized to oral SOC at Day 1 in ATLAS or new patients on SOC, the reasons for willingness to switch ART will be assessed at Day 1.  For 
patients randomized to CAB LA + RPV LA Q4W in ATLAS, the reasons for willingness to continue long-acting ART in ATLAS-2M will be assessed at 
Day 1. 
yy. 
During Maintenance phase Preference Questionnaire (injection to injection/oral to injection) will be administered to all participants at W48 or upon WD if 
prior to W48. “Preference and Reason for OB” questionnaire at Week 152 or upon WD visit if occurred at or before Week 152, will be administered only to 
participants who received oral bridging during the Maintenance and/or Extension Phases. 
zz. 
Refer to Section 5.5 of the protocol for additional information on performing withdrawal assessments.  HIV-1 RNA will be collected as Storage sample only 
if withdrawal assessments coincide with Week 52 or Week 100 (as per Section 5.5)

7.2. 
Screening and Critical Baseline Assessments 
Written informed consent must be obtained from each potentially eligible participant by 
study site personnel prior to the initiation of any Screening procedures as outlined in this 
protocol. The consent form must have been approved by the Institutional Review Board 
(IRB)/Independent Ethics Committee (IEC). After signing an informed consent, 
participants will complete Screening assessments to determine participant eligibility. 
Each participant being screened for study enrolment evaluation will be assigned a 
participant number at the Screening visit. This number will be given sequentially in 
chronological order of participant presentation according to a numeric roster provided by 
GSK. 
7.2.1. 
Screening Assessments 
Eligibility criteria must be carefully assessed at the Screening visit. Physical 
examinations should be conducted as part of normal routine clinical care. Background 
information to be collected at Screening includes demography and prior ART history. 
Eligible participants may be randomly assigned immediately as soon as all Screening 
assessments are complete and the results are available and documented. All participants 
will complete the screening period of approximately 14 days prior to Baseline (Day 1) 
during which all clinical and laboratory assessments of eligibility must be performed and 
reviewed. The Screening period may be extended to 35 days to accommodate availability 
of all Screening assessment results, completion of source document verification to satisfy 
the Inclusion and Exclusion Criteria, and scheduling. All Screening results must be 
available prior to randomization.  
All information about the participant’s current regimen must be available for 
review by the Principal Investigator or designee prior to randomization.  Source 
documents from other medical facilities must be located/received during the 14 day 
(up to 35 days) screening period and under no circumstances may the participant be 
randomized in the absence of source documentation even if there are delays in 
receipt of this information. 
Any available prior genotypic resistance testing must be provided to GSK, after screening 
and before randomization according to guidance in the SPM, to provide direct evidence 
of no pre-existing exclusionary resistance mutations. The lack of exclusionary resistance 
mutations must be confirmed by the study virologist, which will be provided before the 
screening window closes. Details on use of RAMOS for tracking historic resistance 
report availability and submission to ViiV Healthcare Virology for evaluation are 
described in the SPM. Details regarding baseline or prior resistance data must be noted in 
the source documentation. 
Participants infected with HBV will not be enrolled in the study.  Evidence of HBV 
infection is based on the results of testing at Screening for hepatitis B surface antigen 
(HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antibody (anti-HBs), 
and HBV DNA.  HBV DNA will only be performed for participants with positive anti-
HBc and negative HBsAg and negative anti-HBs (past and/or current evidence).

Participants with an anticipated need for HCV therapy during the study must not be 
enrolled into this study, as HCV therapy currently includes the prohibited medication 
interferon.  The length of this study should be considered when assessing the potential 
need for therapy. 
All participants will be screened for syphilis. Participants with untreated syphilis 
infection, defined as a positive RPR without clear documentation of treatment, are 
excluded.  Participants with a serofast RPR result despite history of adequate therapy and 
no evidence of re-exposure may enrol after consultation with the Medical Monitor. 
Participants with a positive RPR test who have not been treated may be rescreened at 
least 30 days after completion of antibiotic treatment for syphilis. 
The eCSSRS (see Section 7.4.6) assessed at the Screening visit will assess the 
participant’s lifetime risk (any suicidal ideation, behavior, etc. occurring over the 
participant’s lifetime).  A positive alert (indicating some risk) is not necessarily 
exclusionary, rather a means to assess overall risk. 
Participants who meet all entry criteria are randomized and assigned a randomization 
number. A single repeat of a procedure/lab parameter is allowed to determine eligibility 
(unless otherwise specified).  Participants not meeting all inclusion and exclusion criteria 
at initial screen may be rescreened and receive a new participant number one time unless 
they were excluded for reason of having exclusionary historic genotypic resistance.  
Participants who are randomized into the trial and subsequently withdrawn from the 
study for any reason may not be rescreened. 
7.2.2. 
Baseline Assessments 
At Day 1 and prior to randomization, any changes to the eligibility parameters must be 
assessed and any results required prior to randomization (e.g., Day 1 urine pregnancy test 
for women of childbearing potential) must be available and reviewed. The following 
demographic parameters will be captured: year of birth, sex, race and ethnicity. 
Medical/medication/family history will be assessed as related to the inclusion/exclusion 
criteria listed in Section 5.  
HIV-1 genotypic resistance testing and plasma HIV-1 RNA measurement results from 
Screening must be available prior to the Baseline visit. 
Baseline information to be collected at Day 1 includes general medical history and 
current medical conditions. Laboratory and health outcomes assessments will also be 
assessed.  Questionnaire/surveys are recommended to be administered at the beginning of 
the visit before any other assessments are conducted, in the order specified.  For 
participants who agree to the optional assessment, a whole blood sample for genetic 
research should be collected at Day 1 (if not already collected during participation in the 
ATLAS study). 
In addition to a full routine medical history at Baseline, more detailed information will be 
collected for some disease processes such as: 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
139 
 
• Cardiovascular medical history/risk factors (as detailed in the eCRF) will be 
assessed at Baseline and assessments will include height, weight, blood pressure, 
smoking status and history, pertinent medical conditions (e.g., hypertension, 
diabetes mellitus), and family history of premature cardiovascular disease.  In 
addition, medical history/risk factors for renal disease such as nephropathy, renal 
failure, and nephrolithiasis will be assessed. 
• history of illicit drug use [e.g., cocaine, heroin, and methamphetamine use]); 
• intravenous drug use history; 
• gastrointestinal disease (e.g., GI bleeding, PUD, etc.); 
• metabolic (e.g., Type I or II diabetes mellitus); 
• psychiatric (e.g., depression); 
• renal (e.g., nephrolithiasis, nephropathy, renal failure); and, 
• neurologic disorders 
Procedures conducted as part of the participant’s routine clinical management [e.g., 
laboratory assessments] and obtained prior to signing of informed consent may be 
utilized for Screening or baseline purposes provided the procedure meets the protocol-
defined criteria and has been performed in the timeframe of the study.  Where possible 
local lab results should be confirmed by submission of samples to the central lab.  
7.3. 
Efficacy 
7.3.1. 
Plasma HIV-1 RNA 
Plasma for quantitative HIV-1 RNA will be collected according to the Time and Events 
schedule (Section 7.1).  Methods to be used may include but are not limited to the Abbott 
RealTime HIV-1 Assay lower limit of detection (LLOD) 40 c/mL.  In some cases, (e.g., 
where the HIV-1 RNA is below the lower limit of detection for a given assay) additional 
exploratory methods will be used to further characterize HIV-1 RNA levels. 
7.3.2. 
Lymphocyte Subsets, CD4+ and CD8+ 
Lymphocyte subsets will be collected for assessment by flow cytometry (total 
lymphocyte counts, percentage and absolute CD4+ and CD8+ lymphocyte counts, ratios) 
according to Time and Events schedule (Section 7.1) and Laboratory Assessments 
(Section 7.4.2). 
7.3.3. 
HIV Associated Conditions 
HIV-associated conditions will be recorded as per Time and Events schedule 
(Section 7.1).  HIV-associated conditions will be assessed according to the 2014 CDC 
Revised Classification System for HIV Infection (see Section 11.4).

Clinical Evaluations 
The following clinical evaluations will be performed according to the Time and Events 
schedule: 
• Monitoring and recording of all AEs and SAEs.  Additional information on the 
Time Period and Frequency of Detecting AEs and SAEs is provided in Section 
7.4.3.1. 
• Physical exams should be conducted as part of normal routine clinical care.  
Abnormalities noted during any exam must be recorded in the eCRF (e.g., in the 
current medical conditions or AE logs). 
• Height and weight will be measured and recorded.  Height collected on the Day 1 
(Baseline) only. 
• Vital signs will include systolic and diastolic blood pressure and heart rate 
collected after resting for about 5 minutes.  Temperature will also be collected. 
• Past medical history, family history, social history, medication history.  Targeted 
history on cardiovascular risk (smoking history, family and personal history). 
• HIV-associated conditions will be recorded. 
• Electrocardiogram:  A 12-lead ECG will be performed in a semi-supine position 
after 5 minutes of rest.  On Day 1 (Baseline) of the Maintenance Phase, ECGs 
should be performed in triplicate prior to first dose.  An ECG machine that 
automatically calculates the heart rate and measures PR, QRS, QT, and QTc 
intervals is preferred, and these calculated numbers can be used for reporting 
purposes.  Otherwise, an appropriately qualified ECG reader must interpret the 
results.  The same interpreter should assess all ECGs for each participant for the 
site.  Regardless, each ECG should be reviewed by a qualified ECG reader.  The 
qualified ECG reader will make the non-calculated ECG interpretations.  The 
same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study.  This formula may 
not be changed or substituted once the participant has been enrolled. 
• Regular monitoring of hematology, blood chemistry, urinalysis and fasting 
glucose and lipids (parameters to be tested listed below).   
• Periodic assessment of glucose, insulin, and bone, cardiovascular, and renal 
markers; 
• Pregnancy testing.  A negative urine pregnancy test is required prior to initiation 
of IP, any dose of CAB LA or RPV LA or as required by the Medical Monitor 
following a treatment interruption(s).  If serum testing is required locally, the 
results should be available prior to the visit where urine testing is indicated per the 
Time and Events Schedule (Section 7.1). 
o Participants who are enrolled in the study and have a positive pregnancy 
test during the course of the study, will be allowed to remain in the study, 

TMF-13901227

provided a pregnancy specific ICF addendum is signed by the participant. 
No IP can be continued (oral or LA) in any pregnant participant until the 
benefit/risk assessment is discussed with the participant and the pregnancy 
specific ICF addendum has been signed. See details in Appendix 11. 
o Pregnant participants who remain in the study do not need pregnancy 
testing during the study, for the duration of their pregnancy. 
• Evaluation and documentation of all concomitant medications and blood products.  
• Injection Site Reactions (ISRs) will be assessed clinically during the Maintenance 
and Extension Phases for the following: 
Pain, tenderness, pruritis, warmth, bruising, discoloration, infections, rash, 
erythema, swelling, induration, and nodules (granulomas or cysts).   
• A clinical assessment (using Division of Acquired Immunodeficiency Syndrome 
[DAIDS] grading scale) should be performed both before and after an injection to 
identify resolving and new ISRs.  All injection site reactions are considered 
adverse events.  The clinical assessment and interpretation of any ISR, will be 
documented in the ISR AE eCRF.   
• Columbia Suicide Severity Rating Scale (eC-SSRS) will be assessed as per the 
Time and Events Schedule (see Section 7.1 and Suicidal Risk Monitoring Section 
7.4.6). 
Any appropriately qualified site personnel (e.g., Investigator, sub-Investigator, or study 
coordinator/nurse) can perform assessments. 
7.4.2. 
Laboratory Assessments 
All protocol required laboratory assessments, as defined in the Time and Events Schedule 
(see Section 7.1), must be performed by the central laboratory.  Laboratory assessments 
must be conducted in accordance with the Central Laboratory Manual and Protocol Time 
and Events Schedule.  Laboratory requisition forms must be completed and samples must 
be clearly labeled with the participant number, protocol number, site/centre number, and 
visit date.  Details for the preparation and shipment of samples will be provided by the 
central laboratory.  Reference ranges for all safety parameters will be provided to the site 
by the central laboratory. 
• 
The investigator must review the laboratory report, document this review, and 
record any clinically relevant changes occurring during the study in the AE 
section of the CRF. The laboratory reports must be filed with the source 
documents. Clinically significant abnormal laboratory findings are those which 
are not associated with the underlying disease, unless judged by the investigator 
to be more severe than expected for the participant's condition. 
• 
All laboratory tests with values considered clinically significantly abnormal 
during participation in the study should be repeated until the values return to 
normal or baseline or are no longer considered significantly abnormal by the 
investigator or medical monitor.

• 
If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified and the sponsor 
notified. 
• 
All protocol-required laboratory assessments, must be conducted in accordance 
with the laboratory manual and the protocol Time and Events table.  
If additional non-protocol specified laboratory assessments are performed at the 
institution’s local laboratory and result in a change in subject management or are 
considered clinically significant by the investigator (e.g., SAE or AE or dose 
modification) the results must be recorded in the eCRF.  Local laboratory services may 
be used to verify pending laboratory parameters only after consultation and agreement 
with the study team. 
Refer to the lab manual for appropriate processing and handling of samples to avoid 
duplicate and/or additional blood draws. 
Labs will be automatically graded by the central lab according to the DAIDS toxicity 
scales (See Section 11.2 “Division of AIDS Table for Grading the Severity of Adult and 
Pediatric Adverse Events”). 
For fasting laboratory assessments, an overnight fast is preferred; however, a minimum of 
a 6 hour fast is acceptable. 
Table 8 includes lab parameters to be assessed as per the Time and Events Schedule (see 
Section 7.1).  In addition to the protocol-specified laboratory assessments the study 
Medical Monitor, in collaboration with the site investigator, may request additional 
central laboratory assessments be performed to support safety profiling and case 
management of individual study participants.

7.4.3. 
Adverse Events (AE) and Serious Adverse Events (SAEs) 
The investigator and their designees are responsible for detecting, documenting and 
reporting events that meet the definition of an AE or SAE.  
Please refer to Appendix 10 in Section 11.10 for study management information during 
the COVID-19 pandemic. 
Reporting for medical device deficiencies are covered in Section 11.2 
7.4.3.1. 
Time period and Frequency for collecting AE and SAE information 
• Any SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK 
product will be recorded from the time a participant consents to participate in 
the study up to and including any follow-up contact.  
• All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours. The investigator will 
submit any updated SAE data to the sponsor within 24 hours of it being 
available. 
• AEs will be collected from the start of Study Treatment until the final follow-
up contact, at the timepoints specified in the Time and Events Table (Section 
7.1). 
• All AEs and SAEs associated with medical device deficiencies for associated 
person (iespouse, caregiver, site staff…) will be collected. The associated 
person will be provided with a safety reporting information and authorization 
letter. 
• Medical occurrences that begin prior to the start of study treatment but after 
obtaining informed consent may be recorded on the Medical History/Current 
Medical Conditions section of the eCRF. 
• The method of recording, evaluating and assessing causality of AEs and SAEs 
plus procedures for completing and transmitting SAE reports to GSK are 
provided in Section 11.6, Appendix 6  
• Investigators are not obligated to actively seek AEs or SAEs in former study 
participants. However, if the investigator learns of any SAE, including a death, 
at any time after a participant has been discharged from the study, and he/she 
considers the event reasonably related to the study treatment or study 
participation, the investigator must promptly notify GSK. 
7.4.3.2. 
Method of Detecting AEs and SAEs 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and non-leading verbal questioning of the participant is the preferred method to inquire 
about AE occurrence.  Appropriate questions include: 
• “How are you feeling?”  
• “Have you had any (other) medical problems since your last visit/contact?” 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
145 
 
• “Have you taken any new medicines, other than those provided in this study, 
since your last visit/contact?” 
7.4.3.3. 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts.  All SAEs, and non-serious AEs of special 
interest (as defined in Section 7.4.5) will be followed until resolution, until the condition 
stabilizes, until the event is otherwise explained, or until the participant is lost to follow-
up (as defined in Section 5.5). Further information on follow-up procedures is given in 
Section 11.6, Appendix 6). 
7.4.3.4. 
Prompt Reporting of Serious Adverse Events and Other Events 
SAEs, pregnancies, and liver function abnormalities meeting pre-defined criteria will be 
reported promptly by the investigator to the medical monitor as described in Table 9 once 
the investigator determines that the event meets the protocol definition for that event.  
Any seizure or suspected seizure should be reported in an expedited manner, as noted in 
Table 9. 
Criteria for liver chemistry stopping and follow-up criteria are in Section 5.5.1.

SAE reporting to GSK via electronic data collection tool 
• Primary mechanism for reporting SAEs to GSK will be the electronic data collection 
tool. 
• If the electronic system is unavailable for greater than 24 hours, the site will use the 
paper SAE data collection tool and fax it to the Medical Monitor. 
• Site will enter the serious adverse event data into the electronic system as soon as it 
becomes available. 
• After the study is completed at a given site, the electronic data collection tool (e.g., 
InForm system) will be taken off-line to prevent the entry of new data or changes to 
existing data. 
• If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, the site can report this information on a paper SAE form or to the 
Medical Monitor by telephone. 
• Contacts for SAE receipt can be found  in the Study Reference Manual. 
• The investigator will be required to confirm review of the SAE causality by ticking 
the ‘reviewed’ box at the bottom of the eCRF page within 72 hours of submission of 
the SAE. 
The method of recording, evaluating, and follow-up of AEs and SAEs plus procedures 
for completing and transmitting SAE reports to the medical monitor are provided in the 
SPM.  Procedures for post study AEs/SAEs are provided in the SPM.  Primary and 

TMF-13901227

secondary Medical Monitor/SAE contact information is provided in the Study Reference 
Manual . 
7.4.3.5. 
Disease-Related Events and/or Disease-Related Outcomes Not 
Qualifying as SAEs 
Disease related events (DREs) or outcomes listed in the CDC Classification System for 
HIV-1 Infections (Appendix 4) can be serious/life threatening and will be recorded on the 
HIV-Associated Conditions eCRF page if they occur. However, these individual events 
or outcomes, as well as any sign, symptom, diagnosis, illness, and/or clinical laboratory 
abnormality that can be linked to any of these events or outcomes are not reported to 
GSK as AEs and SAEs even though such event or outcome may meet the definition of an 
AE or SAE.  However, if any of the following conditions applies, then the event must be 
recorded and reported as an AE or SAE (According to severity) ):  
• The investigator determines that the event or outcome qualifies as an SAE 
under part ‘other situations’ of the SAE definition (see Section 11.6.2), or 
• The event is, in the investigator’s opinion, of greater intensity, frequency, 
or duration than expected for the individual participant, or 
• The investigator considers that there is a reasonable possibility that the 
event was related to treatment with the investigational product, or 
• Death occurring for any reason during a study, including death due to a 
disease-related event, will always be reported promptly. 
• Lymphomas and invasive cervical carcinomas are excluded from this 
exemption; they must be reported as SAEs even if they are considered to 
be HIV-related. 
If any of the above conditions is met, then record the event on either the AE or SAE 
page (according to severity) in addition to the HIV Associated Conditions eCRF 
page. If it is categorized as an SAE, report promptly (i.e., expedited reporting, see 
Section 7.4.3.4) to GSK. 
7.4.3.6. 
Regulatory Reporting Requirements for SAEs 
Prompt notification by the investigator to GSK of SAEs related to study treatment (even 
for non- interventional post-marketing studies) is essential so that legal obligations and 
ethical responsibilities towards the safety of participants and the safety of a product under 
clinical investigation are met.  
The Sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a product under clinical investigation.  GSK 
will comply with country specific regulatory requirements relating to safety reporting to 
the regulatory authority, Institutional Review Board (IRB)/Independent Ethics 
Committee (IEC) and investigators. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
149 
 
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary. 
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g., summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements. 
7.4.3.7. 
Cardiovascular and Death Events 
Investigators will be required to fill out the specific CV event page of the eCRF for the 
following AEs and SAEs:   
• Myocardial infarction/unstable angina 
• Congestive heart failure 
• Arrhythmias 
• Valvulopathy 
• Pulmonary hypertension 
• Cerebrovascular events/stroke and transient ischemic attack 
• Peripheral arterial thromboembolism 
• Deep venous thrombosis/pulmonary embolism 
• Revascularisation 
This information should be recorded in the specific cardiovascular eCRF within one week 
of when the AE/SAE(s) are first reported.  The CV CRFs are presented as queries in 
response to reporting of certain CV MedDRA terms. 
For any cardiovascular events detailed above, whether or not they are considered SAEs, 
and all deaths, specific Cardiovascular (CV) and Death sections of the eCRF will be 
required to be completed.  These sections include questions regarding cardiovascular 
(including sudden cardiac death) and non-cardiovascular death.  
The CV CRFs are presented as queries in response to reporting of certain CV MedDRA 
terms.  The CV information should be recorded in the specific cardiovascular section of 
the eCRF within one week of receipt of a CV Event data query prompting its completion. 
  
7.4.3.8. 
Death Events 
The Death CRF is provided immediately after the occurrence or outcome of death is 
reported. Initial and follow-up reports regarding death must be completed within one 
week of when the death is reported. 
In addition, all deaths will require a specific death data collection tool to be completed.  
The death data collection tool includes questions regarding cardiovascular (including 
sudden cardiac death) and noncardiovascular death.

7.4.3.9. 
Medical Device Deficiencies 
Medical devices (vial adaptor -where applicable-, syringe, and needles) are used in this 
study as the study intervention.. To fulfill regulatory reporting obligations worldwide, the 
investigator is responsible for the detecting and documentation of events meeting the 
definitions of device deficiency that occur during the study with such devices.  
The definition of a medical device deficiency can be found in Section 11.2 
NOTE: Medical device deficiencies associated with an SAE will be reported together 
with an SAE form. AEs associated with a medical device deficiency must be documented 
in the eCRF. 
7.4.3.9.1. Time period for Detecting Medical Device Deficiencies 
Medical device deficiencies that result in an incident will be detected, documented, and 
reported during all periods of the study in which the medical device is used.  
If the investigator learns of any device deficiency at any time after a participant has been 
discharged from the study, and such a device deficiency is considered reasonably related 
to a medical device provided for the study, the investigator will notify the sponsor within 
24 hours. 
Medical device deficiencies and any associated AE/SAEs for  associated persons (i.e, 
spouse, caregiver, site staff) will be collected. The associated person will be provided 
with safety reporting information and an authorization letter. 
The method of documenting Medical Device Incidents is provided in Section 11.2 
7.4.3.9.2. Follow-up of Medical Device Deficiencies 
Follow-up applies to all participants and associated persons, including those participants 
who discontinue study treatment or the study 
The investigator is responsible for ensuring that follow-up includes any supplemental 
investigations as indicated to elucidate the nature and/or causality of the deficiency. 
New or updated information will be recorded on the original completed form with all 
changes signed and dated by the investigator. 
7.4.3.9.3. Prompt Reporting of Medical Device Deficiencies to the Sponsor 
Device deficiencies will be reported to the sponsor within 24 hours after the investigator 
determines that the event meets the protocol definition of a device deficiency. 
The medical device deficiency report form will be sent to the sponsor by email.  
The sponsor will be the contact for the receipt of device deficiency reports.

7.4.3.9.4. Regulatory Reporting Requirements for Device Deficiencies 
The investigator will promptly report all device deficiencies occurring with any medical 
device used for CAB+RPV in the study, as described in Section 11.2 in order for the 
sponsor to fulfil the legal responsibility to notify appropriate regulatory authorities and 
other entities about certain safety information relating to medical devices being used in 
clinical studies. 
The investigator, or responsible person according to local requirements (e.g., the head of 
the medical institution), will comply with the applicable local regulatory requirements 
relating to the reporting of device deficiencies to the IRB/IEC.  
 
7.4.4. 
Toxicity Management 
Adverse events that occur during the trial should be evaluated by the Investigator and 
graded according to the Division of AIDS (DAIDS) toxicity scales (See Section 11.2. 
“Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse 
Events”).  Additional information regarding detecting, documenting and reporting AEs 
and SAEs are available in Section 7.4.3 and Section 11.6. 
7.4.4.1. 
Treatment Interruption Due to an Adverse Event 
IP may be interrupted at the discretion of the investigator and according to the severity of 
the AE. If one or more ART medication is held due to toxicity or AEs, all ART 
medications should be held to reduce the risk of development of resistance taking into 
account the length of the planned interruptions and the PK half-life of each ART of the 
regimen, in order to minimize the risk of development of resistance. 
No toxicity-related dose reductions of IP will be allowed.  IP should be restarted as soon 
as medically appropriate; in general, for oral dosing, this should be no longer than 14 
days after discontinuation (unless Grade 3 or 4 toxicities persist).  Any interruption in 
therapy during the Maintenance Phase, oral dosing, of greater than 7 consecutive days 
must be discussed with and agreed by the Medical Monitor prior to resumption of 
therapy.  The Medical Monitor must be contacted upon becoming aware of resumption in 
therapy, if therapy was resumed without prior approval (Section 6.9).  IM dosing is 
expected to occur during the week in which the participant’s projected visit falls (as 
according to the first injection visit).  An additional (+ or -) 7 day window, from the 
projected visit date, is allowable for IM dosing but not preferred.  Any interruption 
outside of this guidance MUST be discussed with the Medical Monitor prior to 
reinitiating IM IP (see Section 6.9.1). 
Guidance is provided below on general participant management and IP interruptions 
based on the severity of the AE.  Information regarding permitted substitutions \ is 
provided in Section 6.8.  All changes in the IP regimen must be accurately recorded in the 
participant’s eCRF.

Note: For participants receiving an ABC-containing product as part of the background 
regimen during the Long-Term Follow-Up (LTFU) Phase, in the event of a 
discontinuation of ABC for any reason, re-initiation of this drug should be undertaken 
with caution. The investigator should obtain a complete history of the events surrounding 
the discontinuation of the ABC-containing product, evaluate for the possibility of a 
clinically suspected HSR, and initiate participant management as outlined in the Local 
Country Prescribing Information, regardless of a participant’s HLA-B*5701 status. 
Screening for the presence of HLA-B*5701 is recommended prior to reinitiating 
treatment with ABC-containing products in participants of unknown HLA-B*5701 status 
who have previously tolerated ABC but is not required to confirm study eligibility. 
7.4.4.2. 
Grade 1 or Grade 2 Toxicity/Adverse Event 
Participants who develop a Grade 1 or Grade 2 AE or toxicity may continue study drug at 
the discretion of the investigator.  Participants who choose to withdraw from the study 
due to a Grade 1 or 2 AE should have study withdrawal and follow-up evaluations 
completed. 
Participants who develop ALT ≥3 times ULN while on study must consult with 
Medical Monitor prior to initiation or continuation of CAB LA + RPV LA 
7.4.4.3. 
Grade 3 Toxicity/Adverse Event 
Participants who develop a Grade 3 AE or toxicity should be managed as follows: 
• 
If the Investigator has compelling evidence that the Grade 3 AE or toxicity has 
not been caused by IP, dosing may continue after discussion with the Medical 
Monitor. 
• 
Participants who develop a Grade 3 AE or toxicity, which the Investigator 
considers related or possibly related to the IP, should have the IP withheld and be 
rechecked each week until the AE returns to Grade 2.  Once the AE is Grade 2, 
IP may be re-started.  
• 
Should the same Grade 3 AE recur within 28 days in the same participant, the IP 
should be permanently discontinued and the participant withdrawn from study.  
• 
Participants experiencing Grade 3 AEs requiring permanent discontinuation of 
IP should be followed weekly until resolution of the AE and to have withdrawal 
study evaluations completed.  A follow-up visit should be performed 2-4 weeks 
after the last dose of IP.  Any participant receiving at least one dose of CAB LA 
and /or RPV LA who discontinue IP / Withdraw will initiate treatment with 
HAART and enter the LTFU Phase for 52 weeks of follow up.  
• 
Participants with Grade 3 asymptomatic laboratory abnormalities should be 
investigated for all potential non-drug related causes, and, following discussion 
with the Medical Monitor, may continue IP if the Investigator has compelling 
evidence that the toxicity is not related to IP, with the exception of liver chemistry 
stopping criteria (See Section 7.4.5.1).  Isolated Grade 3 lipid abnormalities do 
not require withdrawal of IP.

207966 
153 
 
7.4.4.4. 
Grade 4 Toxicity/Adverse Event 
• 
Participants who develop a Grade 4 AE or toxicity must have IP permanently 
discontinued.  However, if the Investigator has compelling evidence that the AE is 
not causally related to the IP, dosing may continue after discussion with, and 
assent from, the Medical Monitor.  Participants should be rechecked each week 
until the AE returns to Grade 2. 
• 
Participants experiencing Grade 4 AEs requiring permanent discontinuation of 
IP should be followed weekly until resolution of the AE and encouraged to 
complete the withdrawal and follow-up study evaluations as noted above.  Any 
participant receiving at least one dose of CAB LA and /or RPV LA who 
discontinue IP / Withdraw will initiate treatment with HAART and enter the 
LTFU Phase for 52 weeks of follow up.  
• 
Participants with Grade 4 asymptomatic laboratory abnormalities should be 
investigated for all potential non-drug related causes, and, following discussion 
with the Medical Monitor, may continue therapy if the Investigator has 
compelling evidence that the toxicity is not related to IP, with the exception of 
liver chemistry stopping criteria (See Section 7.4.5.1).  An in-clinic follow-up 
visit will be performed approximately 2-4 weeks after the last dose of study 
medication if AEs, SAEs, or laboratory abnormalities considered potentially 
harmful to the participant are ongoing at the last on-study visit.  Isolated Grade 4 
lipid abnormalities do not require withdrawal of IP. 
7.4.5. 
Specific Toxicities/Adverse Event Management 
General guidelines for the management of specific toxicities that are considered to be 
associated with treatment of HIV patients.  
Participants who permanently discontinue study drug for reasons of toxicity should be 
followed weekly until resolution of the AE and encouraged to complete the withdrawal 
and Follow-up study evaluations as noted in Section 7.4.3.3. 
7.4.5.1. 
Liver Chemistry Stopping and Follow-up Criteria 
Liver chemistry threshold stopping criteria have been designed to assure participant 
safety and to evaluate liver event etiology during administration of study drug and the 
follow-up phase. All Phase 3 participants who meet liver stopping criteria will be 
adjudicated by the ViiV Safety and Labelling Committee (VSLC) – resulting in a case 
summary, adjudication, and management plan.  The VSLC contains an external expert 
hepatologist, familiar with both DILI and cabotegravir, who will participate in this 
review.  This committee meets on a 3-weekly basis, and can be convened on an ad hoc 
basis as needed.  
7.4.5.2. 
Diarrhea 
Participants with Grade 1 or 2 diarrhea may continue study treatment without 
interruption.  Participants with diarrhea of any toxicity grade may be treated 
symptomatically with anti-motility agents; however, the recommended daily dose of the 
chosen anti-motility agent must not be exceeded.  If symptoms persist or get worse on the 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
154 
 
recommended daily dose of the chosen anti-motility agent then the anti-motility agent 
must be discontinued and consultation made with the Medical Monitor. 
For participants with Grade 3 diarrhea that is unresponsive to the recommended dose of 
the anti-motility agents and for which an alternative etiology (e.g., infectious diarrhea) is 
not established, the treatment with the anti-motility agent and IP must be interrupted until 
resolution of diarrhea to Grade 2 or Baseline, after which IP and background ART may 
be resumed after discussion and agreement with the Medical Monitor.  If Grade 3 
diarrhea recurs within 28 days upon the resumption of IP, the IP should be permanently 
discontinued and the participant withdrawn from the study.  Any participant receiving at 
least one dose of CAB LA and /or RPV LA who discontinue IP / Withdraw will initiate 
treatment with HAART and enter the LTFU Phase for 52 weeks of follow up. 
If loperamide is used for treatment of diarrhea, local prescribing information should be 
followed with respect to dose and frequency of administration.  Loperamide dosing 
should not exceed local prescribing information. 
7.4.5.3. 
Hypertriglyceridemia/ Hypercholesterolemia 
Samples for lipid measurements must be obtained in a fasted state according to the Time 
and Events table (Section 7.1).  Participants who experience asymptomatic triglyceride or 
cholesterol elevations may continue to receive IP.  Clinical management of participants 
with hypertriglyceridemia/hypercholesterolemia should not be based upon non-fasting 
samples (obtained in the fed state).  A confirmatory fasting triglyceride and/or cholesterol 
level should be obtained prior to the institution of medical therapy for hyperlipidemia.  
Isolated Grade 3 and Grade 4 lipid abnormalities do not require withdrawal of IP. 
Please see the Recommendations of the Adult AIDS Clinical Trial Group Cardiovascular 
Disease Focus Group [Dube, 2003] for full discussion of management of hyperlipidemia 
in the context of HIV therapy. 
7.4.5.4. 
Seizures 
A small number of seizure cases have been reported following CAB administration (less 
than 1% of all those receiving CAB in clinical studies).   
. These cases have had alternative explanations for their occurrence. 
ViiV Healthcare has reviewed these cases in detail and does not believe they constitute a 
reasonable likelihood of causation associated with CAB.  This assessment is supported by 
the lack of preclinical signal, class effect or known CNS mechanism, the relatively low 
frequency of seizures relative to expected rates in both healthy and HIV positive 
participants and clinical confounders in each case.  The Sponsor considers the risk of 
developing seizures on the study as being no higher than that of the rest of the HIV-1 
infected population.   
Seizures that occur on study should be managed according to the local guidelines on 
emergency seizure management which may include treatment with benzodiazepines, 
general supportive treatment, exclusion of metabolic and toxicological abnormalities 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

using laboratory tests, septic workup and excluding underlying structural abnormalities 
with neuroimaging. 
Where seizures occur, the Sponsor would like to better characterize these occurrences to 
enable systematic analyses. 
Investigators are requested to document and report seizure or possible seizure events 
promptly (within 24 hours of learning of the event) to the Sponsor for evaluation and 
onward reporting.  Data should be documented on the appropriate eCRF seizure page. 
7.4.5.5. 
Creatine Phosphokinase (CPK) Elevation 
A Grade 3 or higher elevation in CPK should result in a repeat assessment within 2-4 
weeks to ensure the result is transient or due to exercise and will not require a change in 
study treatment.  A history regarding use of drugs known to cause increase of CPK (such 
as statins) physical activity or exercise preceding the CPK evaluation should be obtained.  
Grade 4 elevations in CPK should have a repeat assessment after the participant has 
abstained from exercise for >24 hours.  For persistent Grade 4 CPK elevations that are 
considered possibly or probably related to the IP, IP should be discontinued and the 
participant withdrawn from the study.  Any participant receiving at least one dose of 
CAB LA and /or RPV LA who discontinue IP / Withdraw will initiate treatment with 
HAART enter the LTFU Phase for 52 weeks of follow-up. 
7.4.5.6. 
Lipase Elevations and Pancreatitis 
Participants with asymptomatic Grade 1 or 2 elevations in lipase may be followed closely 
for the development of symptoms. 
Participants with asymptomatic Grade ≥3 elevations in lipase that are considered possibly 
or probably related to IP should have IP interrupted until serum lipase returns to 
Grade 2.  The lipase assay should be repeated within 2 weeks of any Grade ≥3 result.  
Participants with persistence of Grade ≥3 lipase in the absence of other diagnoses or 
reoccurrence of lipase elevation (at Grade ≥2) following reintroduction of IP should 
permanently discontinue IP. 
Participants with a confirmed diagnosis of clinical pancreatitis that is considered possibly 
or probably related to IP should have IP held.  After complete resolution of the episode, 
participants may be re-challenged with IP after discussion with the Medical Monitor, 
only if the Investigator has compelling evidence that the event was not caused by IP.  
Upon re-challenge, lipase determinations should be performed every 2 weeks for at least 
6 weeks after re-initiation of treatment.  With any elevation of lipase of Grade ≥2 or any 
recurrence of symptoms, the participant should discontinue IP and be withdrawn from 
study. 
Any participant receiving at least one dose of CAB LA and /or RPV LA who discontinue 
IP / Withdraw will initiate treatment with HAART and enter the LTFU Phase for 52 
weeks of follow up.

Drug Restart Following Transient Resolving Liver Events Not Related to Study Drug 
Approval by VSLC for drug restart can be considered where: 
Liver chemistries have a clear underlying cause (e.g., biliary obstruction, hypotension, 
and liver chemistries have improved to normal or are within 1.5 × baseline and 
ALT <3 × ULN). Ethics Committee or IRB approval of drug restart must be obtained, as 
required. 
If restart of drug is approved by VSLC in writing, the participant must be provided with a 
clear description of the possible benefits and risks of drug administration, including the 
possibility of recurrent, more severe liver injury or death. 
The participant must also provide signed informed consent specifically for the restart. 
Documentation of informed consent must be recorded in the study chart. 
Study drug must be administered at the dose specified by VSLC.  
Participants approved by VSLC for restarting study drug must return to the clinic once a 
week for liver chemistry tests for a minimum of one month and thereafter for as long as 
clinically indicated and then laboratory monitoring may resume as per protocol. If 
protocol defined stopping criteria for liver chemistry elevations are met, study drug must 
be stopped.

7.4.5.7. 
Decline in Renal Function 
Participants who experience an increase in serum creatinine from Baseline of 
45 micromoles/liter (Mol/L) (or 0.5 milligrams/deciliter [mg/dL]) should return for a 
confirmatory assessment within 2 to 4 weeks.  A urinalysis and urine albumin/creatinine 
and urine total protein/albumin ratios should also be done at this confirmatory visit.  If 
the creatinine increase is confirmed, the investigator should contact the study medical 
monitor to discuss additional follow-up and medical management. 
Participants who have a decline in the estimated GFR (using the CKD-EPI method) of 
>50% from Baseline must return for a confirmatory assessment as soon as possible 
[Levey, 2009]. A urinalysis and urine albumin/creatinine and urine protein/creatinine 
ratios should also be done at this confirmatory visit. If the estimated GFR has declined by 
>50% (confirmed), then study drug should be withheld and the investigator should 
contact the study medical monitor to discuss the rationale for restarting study drugs (if 
appropriate).  Consideration for confounding factors (e.g., background therapy, other 

TMF-13901227

medications, dehydration, concurrent conditions) should be taken into account, and a 
nephrology consult may be obtained.   
7.4.5.7.1. Proximal Renal Tubule Dysfunctions (PRTD) 
PRTD is defined as: 
Confirmed rise in serum creatinine of ≥0.5 mg/dL from Baseline AND serum phosphate 
<2.0 mg/dL; 
Either of the above accompanied by any two of the following: 
Glycosuria (≥250 mg/dL) in a non-diabetic; 
Low serum potassium (<3 mEq/L); 
Low serum bicarbonate (<19 mEq/L). 
Participants meeting criteria for PRTD must return for a confirmatory assessment within 
2 weeks of diagnosis. A urinalysis should also be performed at the time of the 
confirmatory assessment.  If PRTD is confirmed participants should have study drug 
withheld and the investigator should contact the Study medical monitor to discuss the 
rationale for restarting study drugs (if appropriate). Consideration for confounding factors 
(e.g., NRTI backbone, other medications, dehydration, concurrent conditions) should be 
taken into account, and a nephrology consult may be obtained.  If study drug is 
reinitiated, it should have been withheld for no more than 4 weeks. 
7.4.5.8. 
Proteinuria 
Participants with an abnormal urine microalbumin/creatinine ratio (>0.3 mg/mg, 
>300 mg/g, or >34 mg/mmol) that represents a change from Baseline and no associated 
increase in creatinine, should have a repeat spot urine microalbumin/creatinine ratio 
performed within 2-4 weeks. If confirmed, then consideration should be given to 
additional evaluation after consultation with the study medical monitor. Additional 
evaluation may include a 24-hour urine protein and creatinine measurement and 
nephrology referral. 
Participants with an abnormal urine albumin/creatinine ratio (>0.3 mg/mg, 300 mg/g, or 
>34 mg/mmol and representing a change from Baseline) and a serum creatinine increase 
>45 μmol/L (or 0.5 mg/dL) should have confirmation of both results within 2 weeks. If 
confirmed, the study medical monitor should be contacted immediately. Agreement on 
further management should be agreed between the investigator and medical monitor.  
7.4.5.9. 
QTc Prolongation 
Participants with an average QTc interval >550 msec from three or more tracings 
separated by at least 5 minutes should have IP discontinued.  These criteria are based on 
an average QTc value of triplicate ECGs.  If an ECG demonstrates a prolonged QT 
interval, obtain 2 more ECGs over a brief period (~5-10 minutes) and use the averaged 
QTc values of the 3 ECGs to determine whether the participant should be discontinued 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
158 
 
from the study.  If an alternative cause of the QT prolongation is determined (e.g., 
participant receiving drug known to cause prolonged QT or TdP), then IP may be 
restarted after consultation with, and agreement by, the Medical Monitor.  
7.4.5.10. 
Injection Site Reactions (ISRs) 
Injection site reactions will be managed through investigator assessment throughout the 
study.  All ISRs that are either serious, Grade 3 or higher, or persisting beyond 2 weeks 
must be discussed with the Medical Monitor to determine etiology and assess appropriate 
continued study participation.   
Digital photographs may be documented where possible on all participants who have an 
injection site reaction, with observable findings, that is either serious or Grade 3 or 
higher, or that persists beyond 2 weeks.  Dermatology will be consulted on all 
participants who have an injection site reaction considered serious, Grade 3 or above, or 
if clinically significant and persistent beyond 30 days and others if the Investigator or 
Medical Monitor feels it is medically necessary. 
Details regarding photo collection and any other follow up will be given by the Medical 
Monitor at the time of assessment. 
ISR discomfort can be managed symptomatically (e.g., cold/warm compress, 
acetaminophen, ibuprofen) if the reaction is interfering with the participant’s ability to 
perform activities of daily living.  The required intervention should be documented on the 
appropriate eCRF page. 
7.4.5.11. 
Allergic reaction 
Participants may continue study drug for Grade 1 or 2 allergic reactions at the discretion 
of the Investigator.  The participant should be advised to contact the Investigator 
immediately if there is any worsening of symptoms or if further systemic signs or 
symptoms develop. Antihistamines, topical corticosteroids, or antipruritic agents may be 
prescribed.  
Participants with Grade ≥3 allergic reactions that are considered to be possibly or 
probably related to the study drug should permanently discontinue the CAB LA + RPV 
LA regimen and the participant should be withdrawn from the study.  Participants should 
be treated as clinically appropriate and followed until resolution of the AE. 
7.4.5.12. 
Abacavir Hypersensitivity Reaction (ABC HSR) 
The most significant toxicity associated with ABC is the well-characterized drug-related 
hypersensitivity reaction (HSR).  A detailed clinical description of this reaction 
(including the type and severity of events that can occur on re-challenge or reintroduction 
following ABC interruption for non-HSR reasons) and guidance regarding its 
management are included in the Local Country Prescribing Information for EPZICOM.  
Investigators must familiarize themselves with this information on ABC HSR in the 
Local Country Prescribing Information for each of these products prior to initiating 
participants on ABC therapy. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

Studies have shown that carriage of the HLA-B*5701 allele is associated with a 
significantly increased risk of a HSR to ABC.  In the prospective study CNA106030 
(PREDICT-1), the use of pre-therapy screening for the presence of HLA-B*5701 and 
subsequently avoiding ABC in HLA-B*5701 positive patients, significantly reduced the 
incidence of clinically suspected ABC HSR from 7.8% (66 of 847) to 3.4% (27 of 803) 
(p<0.0001).  In clinical studies EPZ108859 (ARIES) and CNA109586 (ASSERT), 0.8% 
(4/515) and 3.1% (6/192) of participants who were HLA-B*5701 negative and who 
received ABC developed a clinically suspected ABC HSR, respectively. 
In any participant treated with ABC, the clinical diagnosis of suspected HSR (as 
detailed in the Local Country Prescribing Information) must remain the basis of 
clinical decision making.  Regardless of HLA-B*5701 status, it is important to 
permanently discontinue ABC and not re-challenge with ABC (i.e., ZIAGEN, 
EPZICOM/KIVEXA, TRIZIVIR, or TRIUMEQ) if a HSR cannot be ruled out on 
clinical grounds, due to the potential for a severe or even fatal reaction. 
7.4.5.12.1. Essential Patient Information 
With reference to Local Country Prescribing Information and the ‘Participant Information 
and Consent Form’, Investigators must ensure that participants are fully informed 
regarding the following information on the hypersensitivity reaction prior to commencing 
ABC therapy: 
• Participants must be made aware of the possibility of a hypersensitivity reaction 
to abacavir that may result in a life-threatening reaction or death and that the risk 
of a hypersensitivity reaction is increased in individuals who are HLA-B*5701 
positive. 
• Participants must also be informed that HLA-B*5701 negative individuals can 
also experience abacavir hypersensitivity reaction.  Therefore, ANY participant 
who develops signs or symptoms consistent with a possible hypersensitivity 
reaction to abacavir MUST CONTACT their doctor IMMEDIATELY. 
• Participants who are hypersensitive to abacavir should be reminded that they must 
never take any abacavir containing medicinal products (e.g., ZIAGEN, 
EPZICOM, KIVEXA, TRIZIVIR, or TRIUMEQ) again, regardless of their HLA-
B*5701 status. 
• In order to avoid restarting abacavir, participants who have experienced a 
hypersensitivity reaction should be asked to return any remaining EPZICOM / 
KIVEXA tablets to the Investigator or site staff. 
• Participants, who have stopped abacavir for any reason, and particularly due to 
possible adverse reactions or illness, must be advised to contact their doctor 
before restarting EPZICOM / KIVEXA as more severe symptoms may recur 
within hours and may include life-threatening hypotension and death. 
• Each participant should be reminded to read the Package Leaflet included in the 
EPZICOM / KIVEXA pack.  They should be reminded of the importance of 
removing the Alert Card included in the pack, and keeping it with them at all 
times.

7.4.5.12.2. Reporting of Hypersensitivity Reactions 
If a clinically suspected case of HSR to ABC meets one of the International Conference 
on Harmonization (ICH E2A, 1994 definitions of seriousness listed in Section 11.6.2 
then, in addition to reporting the case as an SAE, the ABC HSR eCRF should also be 
completed within one week of the onset of the hypersensitivity reaction.  Clinically 
suspected cases of HSR to ABC that do not meet criteria as an SAE can be recorded as an 
AE. 
7.4.5.13. 
Rash Without ABC HSR Symptoms 
Including serious skin reactions such as Stevens-Johnson Syndrome, Toxic 
Epidermal Necrolysis, Erythema Multiforme or rash with significant liver 
dysfunction.  
Participants should be instructed to contact the Investigator as soon as possible if they 
develop a rash on study. 
Participants who develop rash of any grade should be evaluated for the possibility of an 
ABC HSR or a serious skin reaction such as Stevens - Johnson syndrome (SJS), Toxic 
Epidermal Necrolysis (TEN) or Erythema Multiforme.  SJS, TEN, and Erythema 
Multiforme have been reported very rarely in patients taking ABC-containing products.  
These patients generally do not have the cluster of additional symptoms (e.g., 
gastrointestinal and respiratory) that characterize the ABC HSR, but they do have 
features typical of these serious skin reactions. 
If a serious skin reaction develops, ABC (and / or all other concurrent medication(s) 
suspected in the Investigators causality assessment) should be discontinued, and the 
participant should not be re-challenged with any ABC-containing medicinal product (i.e., 
ZIAGEN, TRIZIVIR, EPZICOM, or KIVEXA). 
As many products other than abacavir also cause rash and/or serious skin reactions, all 
other medicinal products that the participant is receiving should also be reviewed and 
discontinued as appropriate. 
The following guidance is provided for clinical management of participants who 
experience rash alone in the absence of accompanying diagnosis of ABC HSR, systemic 
or allergic symptoms or signs of mucosal or target lesions. 
CAB is an analogue of DTG and mild to moderate rash is an expected adverse reaction 
for DTG-containing ART.  Episodes generally occur within the first ten weeks of 
treatment, rarely require interruptions or discontinuations of therapy and tend to resolve 
within two to three weeks.  No instances of serious skin reaction, including 
Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and erythema 
multiforme, have been reported for DTG in clinical trials.  For further characterization of 
HSR and rash observed with DTG-containing ART, please see the current version of the 
CAB IB . 
Rash is an adverse drug reaction (ADR) for RPV.  In clinical trials, most rashes emerged 
during the first 4 weeks of treatment, were transient, and usually mild (Grade 1) to 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
161 
 
moderate (Grade 2).  There were no Grade 4 rashes and none were serious.  Treatment-
related Grade 3 rash was reported in 0.1% of participants in the RPV group.  Treatment-
related rash led to permanent discontinuation in 0.1% of participants in the RPV group.  
No cases of erythema multiforme, SJS or TEN have been reported during clinical 
development of RPV. 
Participants with an isolated Grade 1 rash may continue study drug at the Investigator’s 
discretion.  The participant should be advised to contact the Investigator immediately if 
there is any worsening of the rash, if any systemic signs or symptoms appear, or if 
mucosal involvement develops. 
Participants may continue study drug for an isolated Grade 2 rash.  However, study drug 
(and all other concurrent medication(s) suspected in the Investigators causality 
assessment) should be permanently discontinued for any Grade ≥2 rash that is associated 
with an increase in ALT.  The participant should be advised to contact the physician 
immediately if rash fails to resolve (after more than two weeks), if there is any worsening 
of the rash, if any systemic signs or allergic symptoms develop, or if mucosal 
involvement develops. 
Participants should permanently discontinue study drug [and all other concurrent 
medication(s) suspected in the Investigators causality assessment] for an isolated Grade 3 
or 4 rash, except where the etiology of the rash has been definitively diagnosed as NOT 
attributable to study drug (see below), and the participant should be withdrawn from the 
study.  Participants should be treated as clinically appropriate and followed until 
resolution of the AE.  Every effort should be made to collect as much information as 
possible about the evolution of the event and any relationship with potentially related 
medical events (e.g., viral infection) or start of concomitant medication. 
The rash and any associated symptoms should be reported as adverse events and 
appropriate toxicity ratings should be used to grade the events (based on DAIDS toxicity 
gradings – see Section 11.2, Appendix 2). 
However, if the etiology of the rash has been definitively diagnosed as being unrelated to 
study drug and due to a specific medical event or a concomitant infection or a 
concomitant non-study medication, routine management should be performed and 
documentation of the diagnosis provided.  In this situation, the study drug should be 
continued.  
Participants in the Follow-Up Phase who are receiving ABC as part of their regimen 
should be evaluated for the possibility of a clinically suspected ABC HSR and managed 
appropriately as outlined in the local prescribing information for ABC. 
Any rash that is possibly related to study drug, and is present between Day 1 and 
The Week 4b visit for participants in the Oral Lead-in Phase, must be discussed 
with the Medical Monitor prior to initiation of CAB LA or RPV LA. 
Any participant receiving at least one dose of CAB LA and /or RPV LA who discontinue 
IP / Withdraw will initiate treatment with HAART and enter the LTFU Phase for 52 
weeks of follow-up.

7.4.6. 
Suicidal Risk Monitoring 
Participants with HIV infection may occasionally present with symptoms of depression 
and/or suicidal ideation or behavior.  In addition, there have been some reports of 
depression, suicidal ideation and behavior (particularly in participants with a pre-existing 
history of depression or psychiatric illness) in some patients being treated with INIs.  
Additionally, depression and anxiety has been reported in some participants being treated 
with RPV.  Therefore, it is appropriate to monitor and closely observe participants 
prospectively before and during treatment for suicidal ideation and/or behavior, or any 
other unusual changes in behavior.  It is recommended that the Investigator consider 
mental health consultation or referral for participants who experience signs of suicidal 
ideation or behavior. 
Participants presenting with new onset/treatment emergent depression should be advised 
to contact the investigator immediately if symptoms of severe acute depression (including 
suicidal ideation/attempts) develop, because medical intervention and discontinuation of 
the study medication may be required. 
Assessment of treatment-emergent suicidality will be monitored during this study using 
the electronic version of the Columbia Suicide-Severity Rating Scale (eC-SSRS).  The 
definitions of behavioural suicidal events used in this scale are based on those used in the 
Columbia Suicide History Form [Posner, 2007].  Questions are asked on suicidal 
behavior, suicidal ideation, and intensity of ideation.  Screening visit questions will be in 
relation to lifetime experiences and current experiences (within the past 2 months) and all 
subsequent questioning in relation to the last assessment.  The eC-SSRS is to be 
administered as a patient completed questionnaire specified in the Time and Events Table 
(Section 7.1).  The eC-SSRS will be conducted electronically by telephone or by 
computer/tablet connected to the internet. 
Additionally, the investigator will collect information using the Possible Suicidality-
Related AE (PSRAE) eCRF form in addition to the Adverse Event (non-serious or 
Serious Adverse Events) eCRF form on any participant that experiences a possible 
suicidality-related adverse event while participating in this study.  This may include, but 
is not limited to, an event that involves suicidal ideation, a preparatory act toward 
imminent suicidal behavior, a suicide attempt, or a completed suicide.  The investigator 
will exercise his or her medical and scientific judgment in deciding whether an event is 
possibly suicide-related.  PSRAE forms should be completed and reported to ViiV/GSK 
within one week of the investigator diagnosing a possible suicidality-related adverse 
event.  All sites should have a plan in place for managing possible risks for suicide 
related events.   
7.4.7. 
Pregnancy 
7.4.7.1. 
Pregnancy testing 
Women of childbearing potential must have a negative pregnancy test at Screening, and 
at Baseline (Day 1).  Pregnancy testing will also be conducted as per the Time and Events 
Table (Section 7.1) and at anytime during the trial when pregnancy is suspected. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

If pregnancy is confirmed, a discussion with the pregnant study participant assessing the 
benefit/risk assessment of continuing in the study will be undertaken. If, after this 
discussion, the participant would like to continue in the study, this will be allowed, 
provided the pregnant participant signs the pregnancy specific ICF addendum. See 
Appendix 11 for details. 
Pregnant participants who remain in the study do not need pregnancy testing during the 
study, for the duration of their pregnancy. 
Additionally, the Medical Monitor may request that a urine pregnancy test be performed 
in the event of a treatment interruption greater than 7 days. 
7.4.7.2. 
Rationale for Continued Use in Pregnancy 
Additional data regarding the use of CAB + RPV LA during pregnancy, and management 
of pregnant participants remaining in the study are found in Appendix 11 
The use of CAB + RPV LA during pregnancy may offer unique benefits. It is well 
documented that treatment adherence challenges to oral therapy exists both in the peri-
partum and post-partum periods with LA dosing offering a unique opportunity to 
overcome such adherence challenges. LA therapy may also help with nausea (50 % mild 
to moderate) or hyperemesis (2%) that is frequently seen, especially during the first 
trimester of gestation. 
Participants on LA dosing who become pregnant will have exposures throughout 
pregnancy due to the long half-life and PK tail of CAB/RPV. Prior to this protocol 
amendment, pregnant participants would have been withdrawn from the study, and 
initiated on an alternative oral ART regimen. Alternative regimens consist of either 2 or 3 
antiretrovirals to protect the life of the mother and for the prevention of MTCT. This 
regimen, combined with the long half-life and PK tail of CAB/RPV, would potentially 
expose the fetus to additional ARVs during gestation (in some cases upwards of 5 
antiretrovirals). 
Given the risk/benefit ratio for cabotegravir and rilpivirine LA dosing in WOCBP, 
coupled with concerns of increasing fetal exposure to several additional antiretrovirals 
upon participant withdrawal, this amendment to the protocol will allow pregnant 
participants to remain in the study after a pregnancy specific ICF addendum is signed by 
the participant. 
7.4.7.3. 
Time Period for Collecting Pregnancy Information 
Pregnancy information will be collected from Day 1 until the last follow-up assessment.  
This includes the entirety of the LTFU Phase. 
Pregnant study participants who consent to remain in the study during pregnancy will 
continue to have all clinical assessments (with the exception of pregnancy test) performed 
as per the Time and Events Table (Section 7.1) ,  including the collection of additional 
PK samples for CAB and RPV. See Appendix 11 for details.  

TMF-13901227 
CONFIDENTIAL

Pregnant participants who have received at least one dose of CAB LA or RPV LA and 
decide NOT to continue in the study during pregnancy will enter the  the LTFU Phase of 
the study and will be monitored for 52 weeks after the last LA dose. Moreover, an 
alternative oral HAART will be initiated, at the discretion of the PI and in discussion with 
the Medical Monitor and If a participant becomes pregnant within 52 weeks of the last 
dose of study drug the participant should notify the study site. 
For women who become pregnant while on LA therapy and who consent to continue with 
LA dosing, a descriptive analysis for these women will be obtained and will include but 
not be limited to VLs, CD4 cell count, CAB and RPV plasma concentrations and 
unbound [CAB] concentrations during pregnancy in addition to the first post-partum visit 
after delivery.  
7.4.7.4. 
Action to be Taken if Pregnancy Occurs 
Any pregnancy that occurs during study participation must be reported using a clinical 
trial pregnancy form.  To ensure participant safety, if a pregnancy is reported then the 
investigator should inform GSK within 24 hours of learning of the pregnancy and should 
follow the procedures outlined in Appendix 7. 
Pregnant participants who elect to continue in the study and receive  CAB + RPV LA 
must sign a pregnancy specific ICF addendum. Cabotegravir and rilpivirine are detected 
in systemic circulation for up to 12 months or longer after discontinuing injections of 
CAB + RPV LA; therefore, consideration should be given to the potential for fetal 
exposure during pregnancy and should be discussed between the study participant and the 
study PI. Participants who become pregnant during the study and elect to continue in the 
study and receive CAB+RPV LA, will have additional samples collected (including PK 
samples to monitor cabotegravir and rilpivirine exposure levels throughout the 
pregnancy, see Appendix 11) and at the time of delivery.   
The pregnancy must be followed up to determine outcome (including premature 
termination) and status of mother and child(ren).  Pregnancy complications and elective 
terminations for medical reasons must be reported as an AE or SAE.  Spontaneous 
abortions must be reported as SAEs. 
Any SAE occurring in association with a pregnancy brought to the investigator’s 
attention after the participant has completed the study and considered by the investigator 
as possibly related to the study treatment, must be promptly reported to ViiV/GSK. 
GSK’s central safety department will also forward this information to the Antiretroviral 
Pregnancy Registry.  The international registry is jointly sponsored by manufacturers or 
licensees of ARV products.  Additional information and a list of participating 
manufacturers/licensees are available from http://apregistry.com/index.htm.

7.4.8. 
Physical Exams 
Physical exams should be conducted as part of normal routine clinical care.  
Abnormalities noted during any exam must be recorded in the eCRF (e.g., in the current 
medical conditions or AE logs). 
• A complete physical examination will include, at a minimum, assessment of 
the Cardiovascular, Respiratory, Gastrointestinal, and Neurological systems.  
Height and weight will also be measured and recorded as per the Time and 
Events Table in Section 7.1 above.  
• A brief physical examination will include, at a minimum assessments of the 
skin, lungs, cardiovascular system, and abdomen (liver and spleen). 
• The site of IM injection administration should be assessed at every visit for 
signs of any possible reaction.  See Section 7.4.5.10 for additional information. 
• Investigators should pay special attention to clinical signs related to previous 
serious illnesses. 
7.4.9. 
Vital Signs 
Vital signs will be measured in semi-supine position after 5 minutes rest and will include 
temperature, systolic and diastolic blood pressure and pulse rate.  These will be recorded 
as per the Time and Events Table in Section 7.1. 
7.4.10. 
Electrocardiogram (ECG) 
A 12-lead ECG will be performed in a semi-supine position.  On Day 1, (Baseline), 
ECGs should be performed in triplicate prior to first dose.  At Day 1 and Week 48 of the 
Maintenance Phase, a 2 hour post dose ECG will be performed for participants receiving 
CAB LA + RPV LA with an allowable window of  30 minutes. An ECG machine that 
automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals is 
preferred, and these calculated numbers can be used for reporting purposes.  Otherwise, 
an appropriately qualified ECG reader must interpret the results.  The same interpreter 
should assess all ECGs for each participant.  Regardless, each ECG should be reviewed 
by a qualified ECG reader.  The qualified ECG reader will make the non-calculated ECG 
interpretations.  Refer to the Time and Events Table for collection timepoints (Section 
7.1).  Refer to Section 5.5.2 for [QTc] withdrawal criteria and additional [QTc] readings 
that may be necessary 
7.5. 
Pharmacokinetics 
Plasma samples for determination of CAB and RPV concentrations will be collected 
throughout the Maintenance and Extension Phases of the study. Additional samples will 
be collected for storage during the LTFU Phase (blood and plasma). Samples (blood and 
plasma) for determination of RPV concentrations will be protected from light at all times, 
from sampling collection through analysis.

Pregnant participants will have additional PK samples collected during the duration of the 
pregnancy. See Appendix 11 for details. 
7.5.1. 
PK Sample Collection 
Blood samples for evaluation of CAB (2mL each) and RPV (2 mL each) plasma PK 
concentrations will be collected from all participants as described in Table 10.  
 
For participants transitioning from oral SOC, at Week 4b PK samples should be collected 
within the window of 20-28 hours after the last oral dose of CAB + RPV was taken the 
day prior to the clinic visit. Participants will take their final dose of oral CAB + RPV in 
the clinic at Week 4b after the pre-dose PK sample.  
These participants will be expected to complete a PK dosing diary card noting the date 
and time of the last three oral doses of IP prior to the scheduled clinic visits at Week 4b.  
The information from the diary card and the actual date and time of the PK samples will 
be recorded in the eCRF.  Additionally, dosing information on the clinic day, including 
dosing and the actual date and time of the PK samples, must be recorded on the eCRF.   
Plasma concentrations will be summarized and used to evaluate potential exposure-
response relationships. 
The timing of PK samples may be altered and/or PK samples may be obtained at 
additional time points to ensure thorough PK monitoring.

clinic.  Pre-dose sample collection at Week 4b (for participants transitioning from the 
current ART arm) should be collected 20 to 28 hours after the last oral dose of CAB and 
RPV was taken. 
If a participant withdraws from the study a PK sample should be collected as early as 
practically possible (i.e., at withdrawal visit or on the day the withdrawal decision was 
made).

Samples for determination of RPV will be protected from light until analysed.  
7.5.2. 
Rationale of PK Sampling Strategy 
Blood sampling for CAB and RPV concentrations will be performed during the 
Maintenance Phase of the study to evaluate PK in HIV infected participants.  The 
proposed PK visits and sampling scheme at each visit presented in Section 7.1 is based on 
consideration of available PK data to support interim and final PK and 
PK/Pharmacodynamic (PD) analysis planned in this study. 
7.5.3. 
Sample Analysis 
7.5.3.1. 
CAB Sample Analysis 
Plasma CAB analysis will be performed under the control of PTS-DMPK, 
GlaxoSmithKline, the details of which will be included in the Study Reference Manual 
(SRM).  Concentrations of CAB will be determined in plasma samples using the 
currently approved bioanalytical methodology.  Raw data will be archived at the 
bioanalytical site (detailed in the SRM). 
Once the plasma has been analyzed for CAB any remaining plasma may be analyzed for 
other compound-related metabolites and the results reported under a separate GSK PTS-
DMPK, GSK protocol.  No human DNA analysis will be performed on these samples. 
7.5.3.2. 
RPV Sample Analysis 
Plasma RPV analysis will be performed under the control of Janssen R&D. 
Concentrations of RPV will be determined in plasma samples using the currently 
approved bioanalytical methodology.  Raw data will be archived at the bioanalytical site. 
Once the plasma has been analyzed for RPV any remaining plasma may be used by the 
sponsor for further exploratory work on pharmacokinetics, metabolites, plasma protein 
binding, protein analysis, and biochemistry.  No human DNA analysis will be performed 
on these samples. 
7.6. 
Genetics 
Information regarding genetic research is included in Appendix 5: Genetic Research.  
7.7. 
Viral Genotyping and Phenotyping 
Whole venous blood samples will be obtained from each participant to provide PBMCs 
and plasma for storage samples according to the Time and Events Table (see Section 7.1) 
for potential viral genotypic and phenotypic analyses. 
Details concerning the handling, labeling and shipping of these samples will be supplied 
separately. Genotypic and phenotypic analyses may be carried out by Monogram 
Biosciences using, but not limited to, their Standard PhenoSense and GenoSure testing 
methods for protease (PRO), reverse transcriptase (RT), and integrase assays.

7.7.1. 
HIV-1 Polymerase Viral Genotyping and Phenotyping 
Participants meeting confirmed virologic failure will have plasma samples tested for 
HIV-1 PRO and RT genotype and phenotype and HIV-1 integrase genotype and 
phenotype from samples collected at the time of meeting suspected virologic failure; 
these results will be reported to the investigator as soon as available to provide guidance 
for election of an alternative regimen. 
7.7.2. 
HIV-1 Exploratory Analysis 
Additional analyses for HIV-1 resistance may, for example, be carried out on peripheral 
blood mononuclear cell (PBMC) samples collected at Baseline and/or on stored blood 
samples from other relevant time points.  These analyses may include but are not limited 
to additional viral genotyping and/or phenotyping, as well as other virologic evaluations 
such as linkage and minority species analyses, low level HIV-1 RNA quantitation and 
measurement of viral replicative capacity. HIV-1 PRO and RT genotype and phenotype 
and HIV-1 integrase genotype and phenotype will also be determined on the last on-
treatment isolates from participants who have HIV-1 RNA 200 c/mL regardless of 
confirmatory HIV-1 RNA. 
7.8. 
Value Evidence and Outcomes 
Health outcomes assessments will be conducted according to the Time and Events Table 
(Section 7.1).  Assessments are recommended to be administered with a paper instrument 
at the beginning of the visit prior to collection of blood for analysis and other scheduled 
assessments. 
The “Preference” questionnaire will assess whether patients prefer the CAB LA + RPV 
LA injectable treatment or the daily oral ARV regimen, and assess preference for the 
CAB LA + RPV LA Q8W regimen or CAB LA + RPV LA Q4W regimen. The 
“Preference” questionnaire will include 3 questions evaluating preference of HIV 
treatment and the attributes supporting this preference.  
 
The HIV Treatment Satisfaction Questionnaire (HIVTSQ) [Woodcock, 2001 and 
Woodcock, 2006] was developed to evaluate treatments for HIV and patient satisfaction. 
The original HIVTSQ included 10 items and underwent two stages of psychometric 
validation (Woodcock, 2001, Woodcock, 2006). Recently, the HIVTSQ was adapted to 
include injectable treatment for HIV following a qualitative study with HIV patients in 
five European countries.  The adaptation of the HIVTSQ included two additional items 
related to the mode of administration (i.e., long acting intramuscular injection).  These 
are:

Psychometric analyses from three datasets (one from the UK, one from the USA and one 
from the LATTE-2 trial) reveal that the addition of two items in the original version of 
the HIVTSQ is suitable and does not reduce the overall validity of the questionnaire.  The 
current study will be using the HIVTSQs (status version) and the revised HIVTSQc 
(change version) of this recently developed HIVTSQ 12-item questionnaire. The 
HIVTSQ 12-item questionnaire retains the option of calculating the total score as if it 
only had the original 10 items (as the original 10 items are included in the HIV-TSQ12). 
In addition, it allows for calculation of an 11-item scale score including the 
“
” item (item-11). The “
” item (item-12) will be included in 
the questionnaire as a stand-alone item to evaluate potentially painful injectables. These 
measures will assess change in treatment satisfaction over time (in the same participants) 
and compare current satisfaction with previous treatment satisfaction, from an earlier 
time point. 
The Perception of Injection (PIN) questionnaire explores the bother of pain at the 
injection site and ISR, anxiety before and after injection, willingness to receive an HIV 
injectable treatment the following visit and satisfaction with the mode of treatment 
administration of individuals receiving injection and perceptions of individuals associated 
with receiving injections.  The PIN questionnaire was derived from the Vaccines' 
Perception of Injection (VAPI) questionnaire (Chevat, 2009), and adapted for HIV-
infected patients who will receive the CAB LA and RPV LA regimen. This measure 
contains 21 items that measure pain at injection site, local site reactions, impact on 
functioning and willingness to pursue injectable treatment outside of a clinical trial.  
Scores range from 1 to 5, and questions are phrased in such a way as to ensure that 1 
always equated with the most favourable perception of vaccination, and 5 the most 
unfavourable. 
The ACCEPT questionnaire is a generic medication acceptance measure assessing how 
patients weigh advantages and disadvantages of long-term medications (Marant, 2012). 
ACCEPT may be a predictor of patients' future adherence to and/or persistence with their 
treatment. While the ACCEPT questionnaire consists of 25 items that capture six 
dimensions, we will use three questions that focus on general acceptance of study 
medication. 
The HIV/AIDS Targeted Quality of Life (HAT-QoL) instrument [Holmes, 1998] 
originally contained 42 items, grouped into nine dimensions, assessing overall function 
and well-being. For the purposes of this study, ViiV Healthcare is using a shorter version 
adapted from the original version. This shorter version contains 14 items grouped into the 
three following dimensions: “life satisfaction”, “disclosure worries” and “HIV 
medication”. All items use a ‘‘past 4 weeks’’ timeframe and a Likert response scale from 
1=‘‘all of the time’’ to 5=‘‘none of the time’’ 
The “Reason for Switch” question will contain a single item exploring the reasons why 
patients choose to switch study medication. The single item will include six possible 
response options. 
Qualitative interviews with participants and/or health care providers at study sites may be 
conducted regarding their experience with study treatment. These would be conducted

• The “Reason for Switch” question will be administered at Day 1(Baseline) for 
patients randomized from CAB LA + RPV LA every 4 weeks in ATLAS, to 
assess the reasons for willingness to continue long-acting ART. 
• A preference questionnaire will be administered to participants receiving oral 
bridging during the Maintenance and/or Extension Phases in order to explore 
preference for CAB + RPV LA Q4W or Q8W compared to daily oral HIV 
medication at W152 or upon WD visit if occurred at or before Week 152.

STATISTICAL CONSIDERATIONS AND DATA 
ANALYSES 
The study is designed to demonstrate that the antiviral effect of Q8W dosing with CAB 
LA + RPV LA is non-inferior to Q4W dosing CAB LA + RPV LA in subjects stably 
suppressed on an oral SOC regimen or Q4W CAB LA + RPV LA regimen prior to 
randomization.  Non-inferiority in the proportion of participants with HIV-RNA 50 
c/mL at Week 48 (defined by the US FDA snapshot algorithm) can be concluded if the 
upper bound of a two-sided 95% confidence interval for the difference between the two 
treatment arms (Q8W – Q4W) is less than 4%. 
If fQ8W is the snapshot failure rate for Q8W CAB LA + RPV LA, and fQ4W is the snapshot 
failure rate for Q4W CAB LA + RPV LA then the hypotheses can be written as follows: 
H0: fQ8W – fQ4W 4%  vsH1: fQ8W – fQ4W < 4% 
9.1. 
Sample Size Considerations 
This study will randomize approximately 510 participants per arm. Assuming the true 
proportion with HIV-1 RNA 50 c/mL is 3% for the Q8W arm and 2% for the Q4W arm, 
a non-inferiority margin of 4%, and a 2.5% one-sided significance level, this sample size 
would provide at least 85% power to show non-inferiority at Week 48 (using unpooled Z 
test statistic).  With this sample size, 90% power would be achieved assuming a 1% 
treatment difference and true proportions with HIV-1 RNA 50 c/mL of 2.63% for the 
Q8W arm and 1.63% for the Q4W arm. 
With 510 subjects per arm and assuming an observed proportion HIV-RNA 50 c/mL is 
2% for Q4W, the largest observed treatment difference to achieve non-inferiority with 
respect to a 4% margin is 1.92 percentage points.  This equates approximately to 
observing an excess of 10 subjects on the Q8W arm (10 subjects on Q4W vs. 20 subjects 
on Q8W). 
This sample size of 510 participants per arm will also provide at least 90% power (using 
unpooled Z test statistic) to show non-inferiority in the proportion of participants with 
plasma HIV-1 RNA <50 c/mL (per FDA’s snapshot algorithm) at Week 48 over a range 
of true response rates, on the basis of a -10% non-inferiority margin and 2.5% one-sided 
significance level (see Figure 15).  For example, assuming true response rate for the Q8W 
arm and Q4W arm are both 92%, the power is 99% to show non-inferiority for this key 
secondary endpoint. 
9.1.1. 
Rationale for non-inferiority margin 
A non-inferiority margin of 4% has been chosen for this study because a snapshot 
proportion with HIV-1 RNA 50 c/mL at Week 48 in this range is considered clinically 
tolerable given the Q8W regimen will offer important advantages over the Q4W regimen 

TMF-13901227

such as reduced injection frequency, and may offer better adherence and treatment 
satisfaction.  This margin is also in concordance with the current FDA Guidance for 
Industry (FDA, 2015), which is the most current regulatory guidance from either the 
European Medicines Agency (EMA) or FDA and includes specific recommendations 
regarding switch studies. 
9.1.2. 
Assumption for Snapshot Proportion with HIV-RNA 50 c/mL at 
Week 48 (Primary Endpoint) 
For the sample size calculation, assumptions regarding the true proportion with HIV 
RNA  50 c/mL for each arm were informed by data from the LATTE-2 Phase 2b study 
(Table 11).  These data suggest a rate of 2% for Q4W and a possibly higher rate in the 
neighbourhood of 3% for Q8W. 
Two important changes to the current study in relation to the LATTE-2 study were also 
considered in setting the sample size. Firstly, the loading dose schedule for Q8W has 
been modified in an attempt to optimize the pharmacokinetics of CAB LA + RPV LA. 
Secondly, a re-testing strategy (see Section 5.5.5.1) has been added to reduce the number 
of subjects counted as having HIV RNA  50 c/mL in the primary analysis at key 
timepoints because of transient blips (consistent with the FDA’s guidance for the 
Snapshot endpoint).  Through these changes, it is possible that the proportions with HIV 
RNA  50 copies/mL will be lower than that observed in the LATTE-2 study.

9.1.3. 
Assumption for Response Rate at Week 48 (Secondary Endpoint) 
Given the response rates shown in Table 11, a reasonable assumption for the true 
response rate (HIV-1 RNA <50 c/mL) for both arms is 92%. 
9.1.4. 
Sample Size Sensitivity

randomized participants per arm based on calculations using an unpooled Z test statistic 
and asymptotic approximation.  For example, if the true rate for Q8W is 1.5 percentage 
points higher than Q4W (green line), then the study would still have over 80% power to 
meet its primary objective if the Q4W rate is less than 1.3%.   
Figure 15b (right panel) shows the impact on power to changes in the sample size 
assuming a 2% true-rate for Q4W.  Power remains at least 80% for sample sizes as low as 
425 per arm if the true Q8W rate is at most 1-percentage point inferior to Q4W.

Sensitivity of Estimated Power for Snapshot Proportion with HIV-
RNA  50 c/mL 
 
Figure 16a (left panel) shows the sensitivity of the estimated power for the secondary 
endpoint comparison of response rates (HIV-1 RNA <50 c/mL at Week 48) to different 
assumed ‘true’ response rates based on calculations using an unpooled Z test statistic and 
asymptotic approximation.  For example, if the true Q8W rate is two percentage points 
inferior to Q4W (blue line), then power is at least 90% for Q4W rates greater than 82%.   
Figure 16b (right panel) shows the impact on power to changes in the sample size 
assuming an 92% response rate for Q4W.  For example, if the true Q8W rate is 3-
percentage points inferior to Q4W (green line), then power remains at least 90% for 
sample sizes as low as 368 per arm.

Data Analysis Considerations 
9.2.1. 
Analysis Populations 
9.2.1.1. 
Intent-to-Treat Exposed (ITT-E) 
The ITT-E population will consist of all randomly assigned participants who receive at 
least one dose of study drug. Participants will be assessed according to their randomized 
treatment, regardless of the treatment they received.  The population used in the primary 
efficacy analysis will be the ITT-E population. 
9.2.1.2. 
Per-Protocol Population (PP) 
The Per-Protocol (PP) Population will consist of all participants in the ITT-E Population 
with the exception of major protocol violators. The PP will be used for sensitivity 
analysis of the primary endpoint. 
9.2.1.3. 
PK Population 
The PK Population will include all participants who receive CAB and / or RPV and 
undergo PK sampling during the study, and provide evaluable CAB and /or 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

RPV plasma concentration data.  Participants in this population will be included in the 
PK analysis. 
9.2.1.4. 
Safety Population 
The Safety Population will consist of all randomly assigned participants who receive at 
least one dose of study drug. Participants will be assessed according to actual treatment 
received.  Unless otherwise stated, the Safety Population will be used for safety analyses. 
9.2.2. 
Treatment Comparisons 
9.2.2.1. 
Primary Comparison of Interest 
The primary analysis will be based on the ITT-E population.  The primary comparison 
will be made at a one-sided 2.5% level of significance.  Treatment with Q8W will be 
declared non-inferior to Q4W if the upper end of a two-sided 95% confidence interval for 
the difference between the two groups (Q8W – Q4W) in the proportion of participants 
with HIV-RNA 50 c/mL at Week 48 (defined by the US FDA snapshot algorithm) lies 
below 4%. 
9.2.2.2. 
Other Comparisons of Interest 
• The analysis described above will also be performed using the PP population and the 
results will be compared for consistency with the results from the ITT-E population.  
If the primary comparison on interest using the ITT-E population demonstrates non-
inferiority of Q8W compared to Q4W then the following key secondary comparisons 
will be tested: Treatment with Q8W will be declared non-inferior to Q4W with 
respect to the proportion of participants with HIV-1 RNA < 50 copies/mL at Week 48

Planned Analyses 
At least 4 analyses will be conducted to evaluate the objectives of the protocol after all 
subjects have completed their visits at Week 24, Week 48, Week 96, and Week 152 
respectively.  Further data cuts and analyses may be conducted as necessary in order to 
support regulatory submissions and publications (first publication at Week 48).  The 
Week 48 analysis will be primary and no results will be shared publicly until Week 48 
analysis is complete. Full details for the primary Week 48 analysis (and preliminary 
Week 24 analysis) will be prespecified in the RAP prior to the database freeze for the 
Week 24 analysis and sponsor review of any summary of data grouped by actual 
treatment arm.

9.2.3.1. 
Week 24 data analyses 
An analysis of data through Week 24 will be conducted when all subjects have completed 
their Week 24 visit, with the intent of expediting submission of results to health 
authorities. 
The analyses described in Section 9.3.2.2, Section 9.3.3 and Section 9.3.6 will be 
performed. Health outcomes analyses will not be performed. 
There is no intention to stop the study early if positive efficacy findings are seen at Week 
24 and a formal hypothesis test of non-inferiority at Week 24 will not be evaluated. The 
analysis at Week 48 is primary and will overrule the findings based on the Week 24 data.  
Therefore, no multiplicity adjustment to the primary Week 48 treatment comparisons is 
needed because of the analysis of Week 24 data. 
 
Neither investigators nor subjects will be informed of the results of the Week 24 data 
analysis.  Sponsor staff will only review aggregate data by actual treatment arm after the 
Week 24 IDMC evaluation is complete as required in the preparation of submission 
documents. 
 
9.2.3.2. 
IDMC analyses 
Independent review will be provided by an IDMC to ensure external objective medical 
and/or statistical review of efficacy and safety in order to protect the ethical interests and 
well-being of subjects and to protect the scientific validity of this study.  An ad-hoc 
review of data by the IDMC will be triggered whenever the number of confirmed 
virologic failures in the CAB LA + RPV LA Q8W arm exceeds thresholds pre-specified 
in the IDMC charter.  Further, an interim futility analysis will be performed for the 
IDMC to evaluate the efficacy and safety of CAB LA + RPV LA Q8W arm when 
approximately 50% of subjects have completed their visit at Week 24; the sponsor will 
remain blinded to this analysis.  Any additional Week 24 analyses will also be shared 
with the IDMC. Full details of the methods, timing, decision criteria and operating 
characteristics will be pre-specified in the IDMC Charter. 
Since the statistical stopping guidelines will not result in early stopping due to positive 
efficacy findings for the Q8W regimen, these planned analyses will not inflate the type I 
error rate for the primary treatment comparison at Week 48. 
9.3. 
Key Elements of Analysis Plan 
9.3.1. 
Primary Analyses 
For the primary efficacy analysis, virologic outcome for each participant in the Intent-to-
Treat Exposed population will be calculated according to the FDA’s Snapshot algorithm.  
The primary analysis at Week 48 will take place after the last participant has had their 
Week 48 viral load assessed, including a retest if required.  
As defined by the Snapshot algorithm, HIV-RNA  50 copies/mL is determined by the 
last available HIV-1 RNA measurement while the participant is on treatment within the 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
180 
 
analysis visit window of interest.  In addition, participants without evaluable HIV-RNA 
data for the visit of interest and who discontinue from the maintenance phase for reasons 
not related to adverse event with HIV-1 RNA result at the time of discontinuation  
50 copies/mL or who change study treatment not permitted per protocol before the 
analysis window are classified as having HIV-RNA  50 copies/mL. 
For the primary efficacy analysis, the adjusted difference between the randomized arms 
for the proportion of participants with HIV-1 RNA 50 c/mL at Week 48 (according to 
the FDA snapshot algorithm) and its confidence interval will be calculated according to a 
stratified analysis with Cochran-Mantel Haenszel (CMH) weights.  This analysis will 
adjust for the randomization strata (rederived for analysis to correct for stratification 
errors) according to prior exposure to CAB + RPV (0 weeks, 1-24 weeks, >24 weeks).   
The CMH estimate of the common difference in rates across strata will be calculated as 
the weighted average of the strata-specific estimates of the difference in proportion 
between the two arms as follows: 
• 
If nk is the number of Q8W treated participants, mk is the number of Q4W arm 
treated participants, and Nk = nk + mk is the total number of participants in the 
kth stratum, then the CMH estimate is given by

The corresponding two-sided 95% CI will be calculated as: 
 
using the variance estimator given by [Sato, 1989], which is consistent in both sparse data 
and large strata.  The formula for computing the Sato variance estimate will be provided 
in the RAP.  Non-inferiority will be declared if the upper bound of the two-sided 95% 
confidence interval for the difference (Q8W – Q4W) is less than 4%. 
The weighted least squares chi-squared statistic [Fleiss, 1981] will be used to assess 
evidence of treatment difference heterogeneity across strata.  strata, Following Lui and 
Kelly [Lui, 2000], 0.50 will be added to each cell in any strata for which the stratum-

207966 
181 
 
specific rate estimates of either fQ8W or fQ4W are zero or one.  Any heterogeneity found to 
be statistically significant will be explored.  Stratum-specific analyses will also be 
provided.  Investigation of heterogeneity will be confined to the primary endpoint.  Tests 
of homogeneity will be assessed at the one-sided 10% level of significance.  Full details 
will be contained in the RAP. 
On-treatment data collected from extra visits within a window will be included in the 
derivation of the Snapshot response/failure but summary tables using observed case (OC) 
datasets will only use the data captured closest to the target visit date.  Detailed 
explanations of the derivation of visit windows will be included in the RAP.  Any 
changes to the original analysis plan in the protocol will be described in the RAP and/or 
clinical study report (CSR). 
9.3.2. 
Secondary Analyses 
9.3.2.1. 
Key Secondary Efficacy Analysis 
A key secondary analysis will evaluate the proportion of participants with HIV-1 RNA 
<50 c/mL (according to the FDA’s Snapshot algorithm) at Week 48 for the ITT-E 
population.  Participants with last available HIV-1 RNA measurement less than 
50 copies/mL while the participant is on treatment within the analysis visit window of 
interest are classified as responders; participants without evaluable HIV-RNA data for the 
visit of interest or who change treatment not permitted per protocol before the analysis 
window are considered non-responders. Full details on the Snapshot algorithm for 
computation of the proportion with HIV-1 RNA < 50 copies/mL will be contained in the 
RAP.  The adjusted difference between the randomized arms for the proportions (Q8W – 
Q4W) and its confidence interval will be calculated according to a stratified analysis with 
Cochran-Mantel Haenszel (CMH) weights, as described for primary endpoint (Section 
9.3.1). 
A non-inferiority margin of -10% will be used for this secondary comparison, where if 
the lower limit of the 95% confidence interval (CI) of the difference between the rates 
(Q8W – Q4W) is greater than -10%, non-inferiority will be demonstrated. 
9.3.2.2. 
Other Secondary Endpoint Analyses 
The primary analysis (Section 9.3.1) and key secondary efficacy analysis (Section 
9.3.2.1) will be repeated at Week 96 and Week 152 with the only difference being a 
change in time point from Week 48 to Week 96 or Week 152 for determining the 
snapshot outcomes. 
For the Week 24 planned analyses, the adjusted treatment difference in proportion of 
participants with plasma HIV-1 RNA 50 c/mL (FDA Snapshot algorithm, with 95% 
confidence interval) at Week 24 will be calculated using the methodology described in 
Section 9.3.1, but no formal test of non-inferiority will be performed at this early 
timepoint.

Proportion of participants with plasma HIV-1 RNA 50 c/mL and HIV-1 RNA <50 c/mL 
(FDA Snapshot algorithm) at Week 24, Week 48,Week 96, and Week 152 respectively, 
will be summarized using the Snapshot algorithm for the ITT-E population.  Proportion 
of participants with confirmed virologic failures will also be summarized over time.  
Absolute values and change from Baseline in CD4+ lymphocyte count will be 
summarized over time including Week 48, Week 96, and Week 152.  
The proportion of participants with HIV-1 RNA 50 c/mL  based on the snapshot 
algorithm, will be summarized at Week 24, Week 48, Week 96, and Week 152 by 
duration of prior CAB + RPV exposure (0 weeks, 1-24 weeks, >24 weeks)., 
The proportion of participants with HIV-1 RNA < 50 c/mL based on snapshot algorithm, 
will be summarized at Week 48,Week 96, and Week 152 by duration of prior CAB + 
RPV exposure (0 weeks, 1-24 weeks, >24 weeks). 
An observed case dataset, with no imputation for missing data, will be the primary 
dataset used for analysis of safety endpoints.  
The proportion of participants reporting AEs will be tabulated for each treatment group. 
The following summaries of AEs will be provided: 
• Incidence and severity of all AEs 
• Incidence and severity of treatment related AEs 
• Incidence and severity of AEs leading to withdrawal 
• Incidence of SAEs 
Changes from baseline in laboratory will be summarized by visit and treatment group 
including Week 48,Week 96, and Week 152.  In addition, the number and percentage of 
participants with graded laboratory toxicities (based on DAIDS categories) will be 
summarized by treatment group.  
Further details for secondary efficacy, safety, and exploratory endpoint analyses will be 
included in the RAP. 
9.3.3. 
Pharmacokinetic Analyses 
The GSK Division of Clinical Pharmacology Modeling and Simulation (CPMS) will be 
responsible for the PK analysis of CAB.  The Division of Clinical Pharmacology 
Development at Janssen Research and Development will be responsible for conduct or 
oversight of the PK analysis for RPV.  
Actual sampling and dosing times as recorded in the eCRF will be used for analysis.   
Plasma CAB and RPV concentration data will be listed and summarized by week, day, 
and planned sampling time in both tabular and graphical forms.  A composite predose 
(C0) concentration may be estimated for purposes of PK/PD analysis.  Post hoc estimates 
of PK parameters will be determined by population PK modeling separately (see 
Population PK Analysis below).

9.3.4. 
Population PK Analysis: 
CAB LA and RPV LA population PK models will be constructed separately and 
individual Bayesian PK parameter estimates may be obtained, if the quality of the data 
permits.  Data from this study may be merged with previous data to support the model 
building process.  Sources of variability in pharmacokinetic parameters will be 
investigated during population modeling.  Demographic parameters including, but not 
limited to age, gender, ethnic origin, body size (weight, height, body surface area, body 
mass index), and relevant laboratory parameters will be evaluated as potential predictors 
of inter- and intra-participant variability for pharmacokinetic parameters.  Population 
pharmacokinetic modeling will be performed using the non-linear mixed effects software 
NONMEM (ICON; Hanover, MD).  Further details of population pharmacokinetic 
analyses will be described in a separate RAP.  Population PK analyses will be done under 
separate Population-PK Reporting and Analysis Plans, and post hoc PK parameters may 
be determined. 
9.3.5. 
Pharmacokinetic/Pharmacodynamic Analyses 
Relationships between various plasma CAB LA and/or RPV LA PK parameters and 
pharmacodynamic measures (e.g., HIV-1 RNA, or safety measures) may be explored 
using simple correlation analyses or population-based PK/PD approach.  Additional 
factors that may be considered include; e.g., age, weight, BMI, gender, race, Baseline 
HIV-1 RNA, HIV risk factors, CDC HIV-1 stage, and CD4+ cell count.   
Exploratory analyses will be performed to examine the relationship(s) between plasma 
concentrations of CAB and RPV and pharmacodynamic endpoints.  A population 
pharmacokinetic/pharmacodynamic modeling approach may be further applied to model 
the data using the nonlinear mixed effect modeling software, NONMEM (ICON LLC, 
Hanover, MD).  Details of the PK/PD analyses plans for CAB and / or RPV will be 
provided in separate RAPs. 
9.3.6. 
Viral Genotyping/Phenotyping Analyses 
The incidence of treatment emergent genotypic and phenotypic resistance to NRTIs and 
INIs, PIs, and NNRTIs and in particular to current antiretroviral regimen and to CAB or 
RPV will be summarized by treatment arm for subjects meeting confirmed virologic 
failure criteria.  Limited analyses will be conducted for Week 24 planned analyses. 
Details of the analyses to be performed will be specified in the reporting and analysis 
plan (RAP). 
9.3.7. 
Health Outcomes Analyses 
Details of the analyses to be performed for the endpoints described in Section 7.8 will be 
specified in the reporting and analysis plan.  Participant preference for CAB LA + RPV 
LA every 8 weeks or CAB LA + RPV LA every 4 weeks compared to oral ARV regimen, 
and preference for CAB LA + RPV LA every 4 weeks compared to CAB LA + RPV LA 
every 8 weeks will be a key secondary treatment analysis based on the ITT-E population.  
As another key secondary treatment comparison, superiority of Q8W compared to Q4W 

TMF-13901227

with respect to change from baseline in HIVTSQs total score at Week 48 will be tested at 
a two-sided 5% significance level using a linear model based on the ITT-E population. 
9.3.8. 
Genetic Analyses 
See the full protocol for details about the Genetics Analysis Plan. 
9.3.9. 
Other Analyses 
Planned subgroup analyses include: proportion of participants by patient subgroup(s) 
(e.g., by age, gender, BMI, race, HIV-1 subtype, Baseline CD4+, type of oral treatment 
[NNRTI, PI, or INSTI], duration prior CAB LA and RPV LA exposure [0 weeks, 1-24 
weeks, >24 weeks]) with HIV-1 RNA 50 c/mL over time including Week 48,Week 96, 
and Week 152.  
In addition, stratum-specific analyses (unadjusted treatment difference and corresponding 
95% confidence interval) of the primary endpoint (proportion of participants with HIV-1 
RNA 50 c/mL) and key secondary endpoint (proportion of participants with HIV-1 
RNA <50 c/mL) at Week 48 (Week 96, and Week 152) will be performed within each of 
the following patient populations: (Group 1) those currently receiving Standard of Care 
antiretroviral therapy [no prior CAB + RPV exposure] and (Group 2) those receiving 
Q4W CAB LA + RPV LA therapy in the ongoing ATLAS study).  For Group 2, a stratum-
adjusted analysis will also be provided, with adjustment for prior CAB + RPV exposure 
(1 to 24 weeks vs. >24 weeks) using Cochran-Mantel Haenszel (CMH) weights, as 
described in Section 9.3.1. 
Changes from baseline in CD4+ lymphocyte count at Week 48, Week 96, and Week 152 
will also be summarized by subgroups.  Additional details on subgroup analyses will be 
provide in the RAP.   
Further details of exploratory analyses will be presented in the RAP.

Appendix 2: Division of AIDS Table for Grading the Severity 
of Adult and Pediatric Adverse Events Version 2.1, March 
2017 
The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse 
Events (“DAIDS AE Grading Table”) is a descriptive terminology which can be utilised 
for Adverse Event (AE) reporting.  A grading (severity) scale is provided for each AE 
term. 
Estimating Severity Grade for Parameters Not Identified in the Grading Table  
The functional table below should be used to grade the severity of an AE that is not 
specifically identified in the grading table. In addition, all deaths related to an AE are to 
be classified as grade 5.

Appendix 3: Liver Safety – Required actions, Follow up 
Assessments and Study Treatment Restart Guidelines 
11.3.1. 
VSLC Guidelines for Drug Restart after stop for Liver criteria 
 
Drug Restart refers to resuming study treatment following liver events meeting stopping 
criteria in which there is a clear underlying cause (other than DILI) of the liver event 
(e.g., biliary obstruction, pancreatic events, hypotension, acute viral hepatitis). 
Furthermore, there should be no evidence of alcoholic hepatitis or hypersensitivity, and 
the drug should not be associated with HLA markers of liver injury. (Table 12; Figure 
17). 
Restarts should be limited to cases in which there is clear evidence that the 
underlying cause of the liver event is not related to study drug. 
DRUG RESTART 
“Drug restart” can be approved by the VSLC for transient, defined non-drug-induced 
liver injury if no evidence of: 
• 
 immunoallergic injury /HLA association with injury 
• 
alcoholic hepatitis 
Study drug must be held while labs and evaluation are completed to assess diagnosis. 
11.3.2. 
VSLC Decision Process for Drug Restart Approval or Disapproval 
• Principal Investigator (PI) requests consideration of drug re-initiation for a 
participant stable or improving on IP, who exhibits liver chemistry elevation 
meeting participant stopping criteria, which is transient, non-drug-related, and 
liver chemistries have improved to normal or are within 1.5x baseline and 
ALT< 5xULN.  
• GSK Medical Monitor and GCSP Physician to review the participant’s diagnosis 
restart risk factors (Hepatotoxicity Panel consultation is available) and complete 
checklist (Table 12). 
– must present source data defining the patient’s current resistance profile 
with documented evidence of extensive drug resistance and previous drug 
history. 
• The local operating company (LOC) medical director should be informed that 
study drug restart is under consideration and of the final decision, whether or not 
to proceed. 
• Relevant physicians (listed below) must review and agree on action to be taken  
regarding request for drug restart:

Appendix 4: CDC Classification for HIV-1 Infection (2014) 
Note that the CD4+ T-lymphocyte count takes precedence over the CD4+ T-lymphocyte 
percentage in HIV infection stages 1, 2, and 3.  The CD4+ T-lymphocyte should only be 
considered if the count is missing. 
HIV infection, stage 0 
Indicates early HIV infection, inferred from a negative or indeterminate HIV test result 
within 180 days of a positive result.  The criteria for stage 0 supersede and are 
independent of criteria used for other stages. 
HIV infection, stage 1 
• 
Laboratory confirmation of HIV infection with no AIDS-defining condition, and 
o CD4+ T-lymphocyte count of ≥500 cells/L, or 
o CD4+ T-lymphocyte percentage of total lymphocytes of ≥26%. 
HIV infection, stage 2 
• 
Laboratory confirmation of HIV infection with no AIDS-defining condition, and 
o CD4+ T-lymphocyte count of 200 to 499 cells/L, or 
o CD4+ T-lymphocyte percentage of total lymphocytes of 14% to 25%. 
HIV infection, stage 3 (AIDS) 
• 
Laboratory confirmation of HIV infection, and 
o CD4+ T-lymphocyte count of <200 cells/L, or 
o CD4+ T-lymphocyte percentage of total lymphocytes of <14%, or 
o Documentation of an AIDS-defining condition (see below). 
Documentation of an AIDS-defining condition supersedes a CD4+ T-lymphocyte count 
of >200 cells/L and a CD4+ T-lymphocyte percentage of total lymphocytes of >14%.  
HIV infection, stage unknown

Appendix 5: Genetic Research 
Genetic Research Objectives and Analyses 
The objectives of the genetic research are to investigate a relationship between genetic 
variants and:  
• Response to medicine, including CAB + RPV or any concomitant medicines;  
• HIV-1 susceptibility, severity and progression and related conditions.  
Genetic data may be generated while the study is underway or following completion of 
the study.  Genetic evaluations may include focused candidate gene approaches and/or 
examination of a large number of genetic variants throughout the genome (whole genome 
analyses). Genetic analyses will utilize data collected in the study and will be limited to 
understanding the objectives highlighted above.  Analyses may be performed using data 
from multiple clinical studies to investigate these research objectives. 
Appropriate descriptive and/or statistical analysis methods will be used. A detailed 
description of any planned analyses will be documented in a RAP prior to initiation of the 
analysis. Planned analyses and results of genetic investigations will be reported either as 
part of the clinical RAP and study report, or in a separate genetics RAP and report, as 
appropriate. 
Study Population 
Any participant who is enrolled in the clinical study can participate in genetic research. 
Any participant who has received an allogeneic bone marrow transplant must be excluded 
from genetic research. 
Study Assessments and Procedures 
A key component of successful genetic research is the collection of samples during 
clinical studies. Collection of samples, even when no a priori hypothesis has been 
identified, may enable future genetic analyses to be conducted to help understand 
variability in disease and medicine response.   
• A 6 mL blood sample will be taken for deoxyribonucleic acid (DNA) extraction.  
A blood sample is collected at the baseline visit, after the participant has been 
randomized and provided informed consent for genetic research. Instructions for 
collection and shipping of the genetic sample are described in the laboratory 
manual. The DNA from the blood sample may undergo quality control analyses to 
confirm the integrity of the sample.  If there are concerns regarding the quality of 
the sample, then the sample may be destroyed.  The blood sample is taken on a 
single occasion unless a duplicate sample is required due to an inability to utilize 
the original sample.  
The genetic sample is labelled (or “coded”) with the same study specific number used to 
label other samples and data in the study.   This number can be traced or linked back to 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
224 
 
the participant by the investigator or site staff. Coded samples do not carry personal 
identifiers (such as name or social security number).  
Samples will be stored securely and may be kept for up to 15 years after the last 
participant completes the study, or GSK may destroy the samples sooner.  GSK or those 
working with GSK (for example, other researchers) will only use samples collected from 
the study for the purpose stated in this protocol and in the informed consent 
form.  Samples may be used as part of the development of a companion diagnostic to 
support the GSK medicinal product. 
Participants can request their sample to be destroyed at any time. 
Informed Consent 
Participants who do not wish to participate in the genetic research may still participate in 
the study.  Genetic informed consent must be obtained prior to any blood being taken. 
Participant Withdrawal from Study 
If a participant who has consented to participate in genetic research withdraws from the 
clinical study for any reason other than being lost to follow-up, the participant will be 
given a choice of one of the following options concerning the genetic sample, if already 
collected: 
• Continue to participate in the genetic research in which case the genetic DNA 
sample is retained  
• Discontinue participation in the genetic research and destroy the genetic DNA 
sample.  
In the event a participant withdraws from the study and requests destruction of their 
samples then  the site staff must document this in the site study records, complete form F-
GRD-001 and must inform ViiV/GSK via the CRA within 5 days of notification by the 
participant to trigger sample destruction requests.  
Genotype data may be generated during the study or after completion of the study and 
may be analyzed during the study or stored for future analysis.  
• If a participant withdraws consent for genetic research and genotype data has not 
been analyzed, it will not be analyzed or used for future research. 
• Genetic data that has been analyzed at the time of withdrawn consent will 
continue to be stored and used, as appropriate.

207966

Screen and Baseline Failures 
If a sample for genetic research has been collected and it is determined that the 
participant does not meet the entry criteria for participation in the study, then the 
investigator should instruct the participant that their genetic sample will be destroyed. No 
forms are required to complete this process as it will be completed as part of the consent 
and sample reconciliation process.  In this instance a sample destruction form will not be 
available to include in the site files.  
Provision of Study Results and Confidentiality of Participant’s Genetic Data 
ViiV/GSK may summarize the genetic research results in the CSR, or separately, and 
may publish the results in scientific journals.  
ViiV/GSK may share genetic research data with other scientists to further scientific 
understanding in alignment with the informed consent. GSK does not inform the 
participant, family members, insurers, or employers of individual genotyping results that 
are not known to be relevant to the participant’s medical care at the time of the 
study, unless required by law. This is due to the fact that the information generated from 
genetic studies is generally preliminary in nature, and therefore the significance and 
scientific validity of the results are undetermined.  Further, data generated in a research 
laboratory may not meet regulatory requirements for inclusion in clinical care.

participant, temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product. 
• NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a medicinal product. 
 
Events meeting AE definition include: 
• Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medical and scientific judgement of the investigator. 
• Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
• New conditions detected or diagnosed after study treatment administration even 
though it may have been present prior to the start of the study. 
• Signs, symptoms, or the clinical sequelae of a suspected interaction. 
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication (overdose per se will not be reported as an 
AE/SAE unless this is an intentional overdose taken with possible suicidal/self-
harming intent.  This should be reported regardless of sequelae). 
• "Lack of efficacy" or "failure of expected pharmacological action" per se will not be 
reported as an AE or SAE.  However, the signs and symptoms and/or clinical 
sequelae resulting from lack of efficacy will be reported if they fulfil the definition 
of an AE or SAE.

Events NOT meeting definition of an AE include: 
• Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition. 
• The disease/disorder being studied or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
participant’s condition. 
• Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is an AE. 
• Situations where an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen. 
11.6.2. 
Definition of Serious Adverse Events 
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease, etc.). 
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, 
at any dose: 
Results in death 
Is life-threatening 
NOTE: 
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
participant was at risk of death at the time of the event.  It does not refer to an event, 
which hypothetically might have caused death, if it were more severe. 
Requires hospitalization or prolongation of existing hospitalization 
NOTE: 
• In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or out-patient setting.  Complications that occur during hospitalization are 
AEs.  If a complication prolongs hospitalization or fulfills any other serious criteria, 
the event is serious.  When in doubt as to whether “hospitalization” occurred or was 
necessary, the AE should be considered serious. 
• Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 

TMF-13901227

207966 
228 
 
Results in disability/incapacity 
NOTE: 
• The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
• This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday 
life functions but do not constitute a substantial disruption 
Is a congenital anomaly/birth defect 
Other situations: 
• Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the participant or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition.  These should also be considered 
serious. 
• Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse 
Is associated with liver injury and impaired liver function defined as: 
• ALT  3xULN and total bilirubin*  2xULN (>35% direct), or 
• ALT  3xULN and INR** > 1.5. 
* Serum bilirubin fractionation should be performed if testing is available; if unavailable, 
measure urinary bilirubin via dipstick.  If fractionation is unavailable and ALT  3xULN 
and total bilirubin  2xULN, then the event is still to be reported as an SAE. 
** INR testing not required per protocol and the threshold value does not apply to 
participants receiving anticoagulants.  If INR measurement is obtained, the value is to be 
recorded on the SAE form.

11.6.3. 
Definition of Cardiovascular Events 
Cardiovascular Events (CV) Definition: 
Investigators will be required to fill out the specific CV event page of the eCRF for the 
following AEs and SAEs: 
• Myocardial infarction/unstable angina 
• Congestive heart failure 
• Arrhythmias 
• Valvulopathy 
• Pulmonary hypertension 
• Cerebrovascular events/stroke and transient ischemic attack 
• Peripheral arterial thromboembolism 
• Deep venous thrombosis/pulmonary embolism 
• Revascularization 
11.6.4. 
Recording of AEs and SAEs 
AEs and SAE Recording: 
• When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) 
relative to the event. 
• The investigator will then record all relevant information regarding an AE/SAE in 
the eCRF 
• It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to GSK in lieu of completion of the GSK, AE/SAE CRF page. 
• There may be instances when copies of medical records for certain cases are 
requested by GSK.  In this instance, all participant identifiers, with the exception of 
the participant number, will be blinded on the copies of the medical records prior to 
submission to GSK. 
• The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information.  In such cases, the diagnosis will be 
documented as the AE/SAE and not the individual signs/symptoms. 
• Participant-completed Value Evidence and Outcomes questionnaires and the 
collection of AE data are independent components of the study. 
• Responses to each question in the Value Evidence and Outcomes questionnaire will 
be treated in accordance with standard scoring and statistical procedures detailed by 
the scale’s developer. 
• The use of a single question from a multidimensional health survey to designate a 
cause-effect relationship to an AE is inappropriate.

11.6.5. 
Evaluating AEs and SAEs 
Assessment of Intensity 
The investigator will make an assessment of intensity for each AE, SAE and device 
deficiency reported during the study and will assign it to one of the following categories: 
• Mild:  An event that is easily tolerated by the participant, causing minimal 
discomfort and not interfering with everyday activities. 
• Moderate:  An event that is sufficiently discomforting to interfere with normal 
everyday activities 
• Severe:  An event that prevents normal everyday activities. - an AE that is assessed 
as severe will not be confused with an SAE. Severity is a category utilized for rating 
the intensity of an event; and both AEs and SAEs can be assessed as severe. 
• An event is defined as ‘serious’ when it meets at least one of the pre-defined 
outcomes as described in the definition of an SAE. 
 
Assessment of Causality 
• The investigator is obligated to assess the relationship between study treatment and 
the occurrence of each AE/SAE/device deficiency. 
• A "reasonable possibility" is meant to convey that there are facts/evidence or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled 
out. 
• The investigator will use clinical judgment to determine the relationship. 
• Alternative causes, such as natural history of the underlying diseases, concomitant 
therapy, other risk factors, and the temporal relationship of the event to the study 
treatment will be considered and investigated. 
• The investigator will also consult the Investigator Brochure (IB) and/or Product 
Information, for marketed products, in the determination of his/her assessment. 
• For each AE/SAE/device deficiency the investigator must document in the medical 
notes that he/she has reviewed the AE/SAE/device deficiency and has provided an 
assessment of causality. 
• There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK.  However, it is very important 
that the investigator always make an assessment of causality for every event 
prior to the initial transmission of the SAE data to GSK. 
• The investigator may change his/her opinion of causality in light of follow-up 
information, amending the SAE data collection tool accordingly. 
• The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.

Follow-up of AEs, SAEs and device deficiency 
• The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by GSK to 
elucidate as fully as possible the nature and/or causality of the AE, SAE and device 
deficiency. 
• The investigator is obligated to assist.  This may include additional laboratory tests 
or investigations, histopathological examinations or consultation with other health 
care professionals. 
• If a participant dies during participation in the study or during a recognized follow-
up period, the investigator will provide GSK with a copy of any post-mortem 
findings, including histopathology. 
• New or updated information will be recorded in the originally completed CRF. 
• The investigator will submit any updated SAE data to GSK within the designated 
reporting time frames. 
11.6.6. 
Reporting of SAEs to GSK 
SAE reporting to GSK via electronic data collection tool 
• Primary mechanism for reporting SAEs to GSK will be the electronic data collection 
tool 
• If the electronic system is unavailable for greater than 24 hours, the site will use the 
paper SAE data collection tool and fax it to the Medical Monitor. 
• Site will enter the serious adverse event data into the electronic system as soon as it 
becomes available. 
• The investigator will be required to confirm review of the SAE causality by ticking 
the ‘reviewed’ box at the bottom of the eCRF page within 72 hours of submission of 
the SAE. 
• After the study is completed at a given site, the electronic data collection tool (e.g., 
InForm system) will be taken off-line to prevent the entry of new data or changes to 
existing data 
• If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, the site can report this information on a paper SAE form or to the 
Medical Monitor by telephone. 
• Contacts for SAE receipt can be found in the Study Reference Manual.

SAE reporting to GSK via paper CRF 
• Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the Medical Monitor or the SAE coordinator 
• In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable, with a copy of the SAE data collection tool sent by 
overnight mail 
• Initial notification via the telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames. 
• Contacts for SAE receipt can be found in the Study Reference Manual.

Appendix 7: Contraceptive Guidance and Collection of 
Pregnancy Information 
Definitions 
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below) 
Women in the following categories are not considered WOCBP 
a. Premenarchal 
b. Premenopausal female with ONE of the following: 
• 
Documented hysterectomy 
• 
Documented bilateral salpingectomy 
• 
Documented bilateral oophorectomy 
Note:  Documentation can come from the site personnel’s: review of participant’s 
medical records, medical examination, or medical history interview. 
c. Postmenopausal female 
• 
A postmenopausal state is defined as no menses for 12 months without an 
alternative medical cause. A high follicle stimulating hormone (FSH) level in 
the postmenopausal range may be used to confirm a postmenopausal state in 
women not using hormonal contraception or hormonal replacement therapy 
(HRT). However, in the absence of 12 months of amenorrhea, a single FSH 
measurement is insufficient.  
• 
Females on HRT and whose menopausal status is in doubt will be required to 
use one of the non-hormonal highly effective contraception methods if they wish 
to continue their HRT during the study. Otherwise, they must discontinue HRT 
to allow confirmation of postmenopausal status before study enrollment. 
Contraception Guidance 
Female participants of childbearing potential are eligible to participate if they agree to 
use a highly effective method of contraception consistently and correctly as described in 
Table 13.

Failure rate of <1% per year when used consistently and correctly.  
Combined (estrogen and progestogen-containing ) hormonal contraception associated with 
inhibition of ovulation 
• oral 
• intravaginal  
• transdermal  
Progestogen-only hormonal contraception associated with inhibition of ovulation 
• injectable  
Highly Effective Methods That Are User Independent  
• Implantable progestogen-only hormonal contraception associated with inhibition of 
ovulation 
• Intrauterine device (IUD) 
• Intrauterine hormone-releasing system (IUS) 
• bilateral tubal occlusion 
Vasectomized partner  
(A vasectomized partner is a highly effective contraception method provided that the partner is 
the sole male sexual partner of the WOCBP  and the absence of sperm has been confirmed. If 
not, an additional highly effective method of contraception should be used.)  
Sexual abstinence  
(Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study drug. The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and 
the preferred and usual lifestyle of the participant.)  
a. Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent with 
local regulations regarding the use of contraceptive methods for participants in clinical studies.  
 
Pregnancy Testing 
o WOCBP should only be included after a confirmed menstrual period and a 
negative highly sensitive serum pregnancy test  
o Additional pregnancy testing should be performed as per the study Time and 
Events Table.  
o Pregnancy testing will be performed whenever a menstrual cycle is missed or 
when pregnancy is otherwise suspected  
o Pregnancy testing will be performed and assayed in the central laboratory OR 
using the test kit provided by the central laboratory / provided by the sponsor

pregnant participants to remain in the study 
11.7.1. 
Collection of Pregnancy Information 
• The Investigator will collect pregnancy information on any participant who 
becomes pregnant while participating in this study. See Appendix 11 and 11.11.1 
for information to be collected for participants who become pregnant while 
participating in this study. 
• Participants who become pregnant while in the study may remain in study and 
continue scheduled dosing with CAB + RPV LA, once a pregnancy specific ICF 
addendum is signed by the participant. See Appendix 11 for additional data and 
information regarding the management of participants who remain in the study 
while pregnant. Information will be recorded on the appropriate form and 
submitted to GSK within 24 hours of learning of a participant's pregnancy. 
• Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on mother and infant, which will 
be forwarded to GSK.  Generally, follow-up will not be required for longer than 6 
to 8 weeks beyond the estimated delivery date.  
• Any termination of pregnancy will be reported, regardless of fetal status (presence 
or absence of anomalies) or indication for procedure. 
• While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy for medical reasons will be 
reported as an AE or SAE. 
• A spontaneous abortion is always considered to be an SAE and will be reported as 
such.   
• Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to 
GSK as described in this section.  While the investigator is not obligated to 
actively seek this information in former study participants, he or she may learn of 
an SAE through spontaneous reporting.

medical records must be available. 
11.8.9. 
Study and Site Closure 
GSK or its designee reserves the right to close the study site or terminate the study at any 
time for any reason at the sole discretion of GSK. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study 
supplies have been collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is reasonable 
cause and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the sponsor or investigator may include 
but are not limited to: 
• Failure of the investigator to comply with the protocol, the requirements of the 
IRB/IEC or local health authorities, the sponsor's procedures, or GCP 
guidelines 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
240 
 
• Inadequate recruitment of participants by the investigator 
• Discontinuation of further study treatment development 
• If GSK determines such action is needed, GSK will discuss the reasons for 
taking such action with the investigator or the head of the medical institution 
(where applicable).  When feasible, GSK will provide advance notification to 
the investigator or the head of the medical institution, where applicable, of the 
impending action. 
• Upon completion or premature discontinuation of the study, the GSK monitor 
will conduct site closure activities with the investigator or site staff, as 
appropriate, in accordance with applicable regulations including GCP, and 
GSK Standard Operating Procedures. 
• If the study is suspended or prematurely discontinued for safety reasons, GSK 
will promptly inform all investigators, heads of the medical institutions (where 
applicable) and/or institution(s) conducting the study. GSK will also promptly 
inform the relevant regulatory authorities of the suspension or premature 
discontinuation of the study and the reason(s) for the action.   
• If required by applicable regulations, the investigator or the head of the 
medical institution (where applicable) must inform the IRB/IEC promptly and 
provide the reason for the suspension or premature discontinuation. 
11.8.10. 
Records Retention 
• Following closure of the study, the investigator or the head of the medical 
institution (where applicable) must maintain all site study records (except for 
those required by local regulations to be maintained elsewhere), in a safe and 
secure location.   
• The records must be maintained to allow easy and timely retrieval, when 
needed (e.g., for a GSK audit or regulatory inspection) and must be available 
for review in conjunction with assessment of the facility, supporting systems, 
and relevant site staff.   
• Where permitted by local laws/regulations or institutional policy, some or all 
of these records can be maintained in a format other than hard copy (e.g., 
microfiche, scanned, electronic); however, caution needs to be exercised before 
such action is taken.   
• The investigator must ensure that all reproductions are legible and are a true 
and accurate copy of the original and meet accessibility and retrieval standards, 
including re-generating a hard copy, if required.  Furthermore, the investigator 
must ensure there is an acceptable back-up of these reproductions and that an 
acceptable quality control process exists for making these reproductions. 
• GSK will inform the investigator of the time period for retaining these records 
to comply with all applicable regulatory requirements.  The minimum retention 
time will meet the strictest standard applicable to that site for the study, as 
dictated by any institutional requirements or local laws or regulations, GSK 
standards/procedures, and/or institutional requirements.

Study Duration 
In this study, the Extension Phase is intended to provide access to CAB LA + RPV LA 
Q4W or Q8W based on original randomization assignment until the regimen receives 
local (by country) Regulatory approval, and becomes commercially available.  Therefore, 
the duration of the Extension Phase will vary from country to country and is dependent 
on the recruitment time for the study and the time taken to achieve local approval for 
marketing. During this time, participants will be monitored at minimum every 8 weeks to 
ensure they continue to derive clinical benefit from CAB LA + RPV LA.

Appendix 10: COVID-19 Pandemic and Clinical Trial 
Continuity 
Background 
The COVID-19 pandemic presents significant logistical challenges for many clinical sites 
around the world, with variable restrictions being placed on site resources and operations, 
and on an individual participants ability to attend clinic visits.  In some places, medical 
visits are occurring, and in others, research clinics are operating with only emergency 
staff. 
Based on these challenges, it may be necessary to adopt additional measures and 
procedures to protect participant safety, and to ensure that there are no gaps in HIV-1 
treatment for participants enrolled in this clinical study, through continuous access to 
antiretroviral therapy. 
In order to maintain the scientific integrity of the study, and adhere to updated guidance 
from regulators, procedures have also been put into place to ensure that the actions taken 
to mitigate against any impact of COVID-19 are well documented in the trial database. 
A “Memo to Investigators” was issued on March 18th, 2020 and served as a record of 
approved emergency actions being taken within this clinical trial to manage issues related 
to COVID-19.  That memo continues to serve as record of approved actions which can be 
fully implemented by Investigators, in advance of this protocol guidance.  This appendix 
will remain consistent with the guidance provided within the “Memo to Investigators” 
and will also serve to provide additional protocol documentation requirements and 
procedures. 
This appendix outlines the measures which are approved for implementation within this 
clinical trial, to protect patient safety and to ensure the integrity of the clinical trial, as a 
result of COVID-19 only. These measures may be implemented in accordance with any 
requirements and expectations set out by local Independent Review Boards/Independent 
Ethics Committees (IRB/IEC) and National Competent Authorities (NCA), as necessary. 
This appendix does not apply to participant management issues that are unrelated to a 
specific, and documented, impact from COVID-19.  
11.10.1. 
Changes to Study Visits and Study Procedures 
• Where site staff resource is constrained due to COVID-19, IM dosing visits may 
proceed with limited or no other protocol-defined assessments (e.g. lab tests, 
questionnaires, etc.). If lab tests will be missed for more than one consecutive 
visit, the medical monitor must be contacted, to provide guidance for safety 
monitoring.  
• For WOCBP, point of care pregnancy testing should be performed, prior to IM 
dosing. 
• If central laboratory testing cannot be performed at a particular visit, and 
monitoring for safety is required, tests may be performed at an appropriately 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
244 
 
authorised/accredited local laboratory (or other relevant clinical facility), if this 
can be done within local restrictions on physical distancing. The site should 
proactively inform the sponsor about such instances. Local laboratory results may 
be used to inform safety decisions. Results should be retained in source records. 
• When on-site visits are reduced, it is important that the investigator continue 
collecting relevant clinical information, including adverse events, from the 
participant through alternative means, e.g. by telephone contact. 
• There may be cases where the current principal investigator (PI) of a site is 
indisposed for a period and may need to delegate parts of his/her duties 
temporarily, e.g. to a sub-investigator. Any such changes should be documented 
in the site’s source records. Any permanent changes in PI should be 
communicated to the sponsor. 
• There may also be circumstances where immediate actions are required by the 
sponsor and/or investigator, outside of what is contemplated in the protocol, in 
order to protect a study participant from immediate hazard. Any such measures 
will be carefully documented and conducted in accordance with the National 
Competent Authority (NCA)/IRB/IEC regulations. 
 
11.10.2. 
Changes to Informed Consent 
Informed consent should continue per normal procedure and as described in the main 
body of the protocol, to the extent possible. However, there may be circumstances where 
re-consent of participants is needed, and a physical signature on site is not possible. In 
these cases, alternative ways of obtaining such re-consent should be considered, such as 
the participant sending a picture of his/her written consent to the investigator, or the 
investigator contacting the participant by telephone or video call and obtaining verbal 
consent, supplemented with email confirmation.   
Any updated informed consent form or other subject-facing materials should be provided 
to participants by e-mail, mail or courier before re-consent is obtained. Any consent 
obtained this way should be documented in source records and confirmed by way of 
normal consent procedure at the earliest opportunity when participants attend their next 
on-site study visit. 
Any alternative informed consent procedure must be undertaken only after site 
IRB/Ethics Committee agreement and approval. 
 
11.10.3. 
Permissible Use of Antiretroviral Therapy 
In order to minimize the risk of gaps in HIV-1 antiretroviral therapy (ART) for 
participants impacted by COVID-19 in the clinical trial, the following options can be 
considered with regards to ART dosing, in order of preference: 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
245 
 
1. Where possible, and safe to do, please continue to prioritize IM dosing visits in 
order to keep the participants on the protocol-defined regimen 
 
a. Qualified healthcare professionals (HCPs) trained on study procedures can 
administer IM injections outside of the study clinic setting (e.g. home, 
nursing facility, hospital), assuming this can be done safely, without 
compromising investigational product 
preparation/handling/storage/accountability requirements and done in 
accordance with local requirements. Please seek approval by the study 
team on a case-by-case basis. 
 
 
2. If a participant is not able to attend an IM injection visit due to COVID-19 related 
restrictions, the gap in IM dosing should be covered with oral ART, until IM 
dosing can resume. Participants should be reminded of the importance of adhering 
with daily oral dosing. Two options can be approved for oral bridging therapy in 
consultation with the Medical Monitor, listed in order of preference: 
 
a. Oral CAB + RPV  
i. Investigator should request availability of oral CAB + RPV supplies, 
prior to pursuing option b. 
b. Oral standard of care (SOC) commercial ART (prescribed locally) 
 
Oral bridging with CAB + RPV 
The protocol permits oral bridging to cover planned missed injections with oral CAB + 
RPV, only until IM dosing can be resumed.  The start date of oral bridging should be 
within the dosing window for the missed IM dosing visit. This recommendation can be 
used to accommodate requests for oral dosing due to COVID-19. Oral bridging 
recommendations should be followed as per protocol Section 6.8.1. The process and 
required information for requesting oral bridging can be found in your Study Reference 
Manual.  Please continue to reach out to your study medical monitor for approval of oral 
bridging, in order to document use and to ensure expeditious shipment of oral CAB + 
RPV to your site.  
Participants who use oral CAB + RPV as short-term oral bridging are permitted to return 
to IM dosing, on protocol, once the COVID-19 conditions permit resumption of site 
activities.  
The investigator should reach out to the medical monitor to confirm IM restart 
instructions, and to ensure the participant remains appropriate for resumption of IM 
dosing. If oral bridging with CAB/RPV is anticipated to continue for > 2 months, 
additional approval and guidance should be obtained from the medical monitor to 
continue with oral bridging therapy. Loading/Re-initiation doses of CAB + RPV IM may 
be required, depending on the length of oral bridging. 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
246 
 
Oral bridging with Standard of Care Antiretroviral Therapy (SOC ART) 
For participants impacted by COVID-19, where the participant is unable to receive IM 
injections, and oral CAB + RPV is not available for use, oral bridging with any 
commercially available, guideline-recommended, SOC ART regimen is permitted. The 
start date of oral bridging should be within the dosing window for the missed IM dosing 
visit.  Please reach out to your study medical monitor for approval of SOC ART as oral 
bridging, in order to document the use of commercially available SOC ART within the 
study.  In order to assure that participants have access to SOC ART during short-term 
oral bridging, GSK may allow for reimbursement of SOC ART or copayments as needed. 
Participants who use oral SOC ART as short-term oral bridging as a result of COVID-19 
will not be considered formally withdrawn insofar as they wish to continue on the study.  
Individuals who bridge with SOC ART will be permitted to return to IM dosing, on 
study, once the COVID-19 conditions permit resumption of site activities.   
The investigator should reach out to the medical monitor to confirm IM restart 
instructions, and to ensure the participant remains appropriate for resumption of IM 
dosing. If oral bridging with SOC ART is anticipated to continue for > 2 months, 
additional approval and guidance should be obtained from the medical monitor to 
continue with oral bridging therapy.  Loading/Re-initiation doses of CAB + RPV IM may 
be required, depending on the length of oral bridging. 
11.10.4. 
Direct-To-Patient (DTP) Shipment of Oral Study IP  
If a participant is unable to travel to the clinic, either to receive IM injections or to be 
dispensed oral bridging, sites are encouraged to consider DTP shipments of drug, from 
the site, to the participant, to ensure access to medicines.  
• If the study site is considering DTP shipment of oral CAB + RPV investigational 
product (IP), the site must first verify if DTP IP dispensing by 
investigators/hospital pharmacies is locally permitted and whether it requires 
regulatory and/or local ethics pre-approval, or post-hoc notification. 
• The study participant should express his/her agreement for DTP shipment and the 
sharing of their personal information with any third-party couriers (as applicable), 
in accordance with local requirements.  This agreement should be documented in 
source records. 
• Oral CAB + RPV IP can be shipped at ambient temperatures via ground transport 
without a temperature monitoring device, with low risk of temperature excursions. 
Sites are encouraged to use discretion in determining the need for in-transit 
temperature monitoring based on the labelled storage requirements and the 
planned mode of transport and apply this as appropriate.  Shipment of oral CAB + 
RPV via air courier continues to require appropriate temperature monitoring.  For 
shipment conditions of oral medications other than oral CAB + RPV, please 
consult the product labelling. 
• In all cases IP accountability must be maintained, and all DTP dispensing 
documentation should be reflected in source records and dispensing logs per GCP.

• Please refer to your CRA or local study manager for support with the DTP 
process, ensuring reference to current sponsor guidance and arrangement of a 
courier that can support shipment of IMP directly to participants. 
 
11.10.5. 
COVID-19 Experimental Agents 
If any treatments for COVID-19 are planned for a study participant, please consult with 
the study medical monitor to ensure that relevant drug interactions are considered and to 
ensure that continued study participation remains appropriate. 
11.10.6. 
COVID-19 Specific Data Capture 
11.10.6.1. Capturing COVID-19 Specific Protocol Deviations 
In order to summarise the impact of COVID-19 in a systematic way and in line with 
regulatory authorities’ recommendations, any study-level impact around COVID-19 will 
be documented as a protocol deviation. This will include the permissible actions 
summarized in this Appendix, which are taken to protect patient safety, including the use 
of CAB + RPV or SOC ART as oral bridging as well as missed visits and assessments as 
a result of logistical challenges resulting from COVID-19. 
Although the conduct of remote visits and the continuity of antiretroviral therapy, via oral 
bridging, are being utilized to protect patient safety, these events fall outside of the intent 
of the original protocol design, may have an impact on data interpretation, and thus will 
be characterized as protocol deviations for the purposes of data summary and analysis. 
 
Any protocol deviations resulting from COVID-19 will be clearly identified as such 
within the protocol deviation description and summarised separately. 
 
 
11.10.6.2. Capturing COVID-19 Specific AEs and SAEs 
It is important for the study team to describe COVID-19 related adverse events/serious 
adverse events (AEs/SAEs) and their impact on study data and outcomes. Standardization 
of case definitions will facilitate future data analysis.  
Please use the following guidance:  
1. AEs should continue to be evaluated as to whether they meet SAE criteria as 
defined in the protocol, and if so, submitted according to established SAE 
reporting requirements. SAEs and AEs should be submitted following usual 
study procedures and timelines.  
 
2. When an in-person clinic visit is not possible, please conduct a remote telehealth 
visit to assess for, and document any AEs/SAEs. 
3. Investigators should use the WHO definition to classify COVID-19 cases. The 
definition below, released March 20, 2020, represents a time point for 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966

standardized collection. We recognize definitions are likely to continue to 
evolve. When reporting both serious and non- serious adverse events (related 
to COVID-19 infection, investigators should use the following Verbatim 
terms:  
a) Suspected COVID-19 infection; or  
b) Probable COVID-19 infection; or  
c) Confirmed COVID-19 infection  
 
4. Sites should contact the study Medical Monitor for questions related to definitions 
and reporting, and decisions around impact to study drug continuation.  
 
5. A new COVID-19 infection Case Report Form will be added to the eCRF to 
collect additional details about the reported COVID-19 AE or SAE data. It is 
important to collect the correct information from each participant reporting a 
COVID-19 AE or SAE.  Therefore, please use the CRF templates to help you 
collect this information, once available. 
 
WHO Case Definition - March 20, 2020 Version (https://www.who.int/publications-
detail/global-surveillance-for-human-infection-with-novel-coronavirus-(2019-ncov)):  
Suspected case: 
A. A patient with acute respiratory illness (fever and at least one sign/symptom of 
respiratory disease, e.g., cough, shortness of breath), AND a history of travel to or 
residence in a location reporting community transmission of COVID-19 disease 
during the 14 days prior to symptom onset;  
OR  
B. A patient with any acute respiratory illness AND in contact (see definition of 
“contact” below) with a confirmed or probable COVID-19 case (see definition of 
contact) in the last 14 days prior to symptom onset;  
OR  
C. A patient with severe acute respiratory illness (fever and at least one 
sign/symptom of respiratory disease, e.g., cough, shortness of breath; AND 
requiring hospitalization) AND in the absence of an alternative diagnosis that 
fully explains the clinical presentation.  
 
Probable case: 
A. A suspect case for whom testing for the COVID-19 virus is inconclusive

Appendix 11: Information and Guidance for Managing 
Pregnant Participants 
11.11.1. 
Collection of Pregnancy Information 
The Investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study.  
• 
Information will be recorded on the appropriate form and submitted to GSK within 
24 hours of learning of a participant's pregnancy. 
• 
Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on mother and infant, which will be 
forwarded to GSK.  Generally, follow-up will not be required for longer than 6 to 8 
weeks beyond the estimated delivery date. 
• 
Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 
• 
While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy for medical reasons will be 
reported as an AE or SAE. 
• 
A spontaneous abortion is always considered to be an SAE and will be reported as 
such. 
• 
Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK 
as described in the protocol in Section 7.4.3.  While the investigator is not obligated 
to actively seek this information in former study participants, he or she may learn of 
an SAE through spontaneous reporting. 
• 
Females who become pregnant while in the study may remain in study, and continue 
scheduled dosing with CAB + RPV LA, once a pregnancy ICF addendum is signed 
by the participant. 
11.11.2. 
Introduction 
Pregnancy increases the risk of HIV progression, while HIV increases the risk for 
maternal complications from pregnancy and poses the risk of perinatal HIV transmission 
to the unborn fetus.  Mother to child transmission (MTCT) of HIV can occur during 
pregnancy, labor, delivery or postpartum through breastfeeding.  In the absence of any 
interventions, vertical HIV transmission rates approximate 35%, but fall below 5% with 
effective interventions [WHO, 2010].  In the United States and other developed countries, 
the risk of perinatal infection has decreased from 25% without intervention to less than 
2% with intervention [WHO, 2012].  The HIV-infected mother who breastfeeds her 
infant while taking ARVs herself or giving ARVs to her infant reduces the risk of 
transmission to about 2% after 6 months of breastfeeding, or 4% over 12 months 
[UNAIDS, 2011]. 
The 2013 WHO Guidelines thus recommend (strong recommendation, moderate-quality 
evidence) all pregnant and breastfeeding women with HIV should initiate triple ARVs 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
251 
 
(ART), which should be maintained at least for the duration of mother-to-child 
transmission risk. Women meeting treatment eligibility criteria should continue lifelong 
ART [WHO, 2013]. The global benefits anticipated from ART in pregnant women who 
are eligible for treatment include treatment of the mother’s underlying HIV disease, 
eliminating pediatric transmission/infection and reducing sexual transmission of HIV 
Recent recommendation updates to treatment guidelines have included objectives to 
increase HIV screening of patients, including pregnant women (noting the importance of 
adopting HIV screening to be a part of prenatal care). 
The ART recommendation for pregnant females prioritizes the health of women over 
potential risks and increased cost.  For females who are on ARV therapy at the time that 
they become pregnant, the World Health Organization recommends that they continue 
such therapy if they are responding to the ARV. 
In line with this recommendation, this study will allow those females participating in 
207966 who are receiving CAB + RPV LA but become pregnant on study, to continue in 
the study in order to maintain their effective regimen with minimal disruption.  The PK of 
CAB + RPV LA, characterization of the safety of CAB + RPV LA administered during 
pregnancy, and characterization of maternal, birth and infant outcomes following 
treatment with CAB + RPV LA will be examined.  
11.11.3. 
Benefit/Risk Assessment 
Discuss with pregnant participant the benefit-risk of continuing in the study and 
continuing to receive CAB + RPV LA injections, or being withdrawn from study, as a 
result of her pregnancy. All participants who chose to stay in the study during pregnancy, 
and who choose to continue to receive CAB + RPV LA injections will need to sign a 
pregnancy specific ICF addendum. 
There is a pregnancy exposure registry that monitors pregnancy outcomes in women 
exposed to CAB + RPV LA (CABENUVA) during pregnancy. Healthcare providers are 
encouraged to register all pregnant study participants, whether or not they choose to 
remain in the study, by calling the Antiretroviral Pregnancy Registry [Antiretroviral 
Pregnancy Registry (APR) Steering Committee, 2013] at 1-800-258-4263. 
11.11.3.1. Cabotegravir 
Cabotegravir use in pregnant females has not been evaluated and there are insufficient 
human data on the use of during pregnancy to adequately assess a drug-associated risk of 
birth defects and miscarriage.  
The rate of miscarriage is not reported in the APR. The background risk for major birth 
defects and miscarriage for the indicated population is unknown. The background rate for 
major birth defects in a U.S. reference population of the Metropolitan Atlanta Congenital 
Defects Program (MACDP) is 2.7%. The estimated background rate of miscarriage in 
clinically recognized pregnancies in the U.S. general population is 15% to 20%. The APR 
uses the MACDP as the U.S. reference population for birth defects in the general 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
252 
 
population. The MACDP evaluates women and infants from a limited geographic area 
and does not include outcomes for births that occurred at less than 20 weeks’ gestation. 
Animal Data (pre-clinical) 
Cabotegravir was administered orally to pregnant rats at 0, 0.5, 5, or 1,000 mg/kg/day 
from 15 days before cohabitation, during cohabitation, and from Gestation Days 0 to 17. 
There were no effects on fetal viability when fetuses were delivered by caesarean 
although a minor decrease in fetal body weight was observed at 1,000 mg/kg/day (greater 
than 30 times the exposure in humans at the RHD). No drug-related fetal toxicities were 
observed at 5 mg/kg/day (approximately 13 times the exposure in humans at the RHD) 
and no drug-related fetal malformations were observed at any dose. 
Cabotegravir was administered orally to pregnant rabbits at 0, 30, 500, or 2,000 
mg/kg/day from Gestation Days 7 to 19. No drug-related fetal toxicities were observed at 
2,000 mg/kg/day (approximately 0.7 times the exposure in humans at the RHD). 
In a rat pre- and postnatal development study, cabotegravir was administered orally to 
pregnant rats at 0, 0.5, 5, or 1,000 mg/kg/day from Gestation Day 6 to Lactation Day 21. 
A delay in the onset of parturition and increases in the number of stillbirths and neonatal 
deaths by Lactation Day 4 were observed at 1,000 mg/kg/day (greater than 30 times the 
exposure in humans at the RHD); there were no alterations to growth and development of 
surviving offspring. In a cross-fostering study, similar incidences of stillbirths and early 
postnatal deaths were observed when rat pups born to cabotegravir-treated mothers were 
nursed from birth by control mothers. There was no effect on neonatal survival of control 
pups nursed from birth by cabotegravir-treated mothers. A lower dose of 5 mg/kg/day (13 
times the exposure at the RHD) was not associated with delayed parturition or neonatal 
mortality in rats. Studies in pregnant rats showed that cabotegravir crosses the placenta 
and can be detected in fetal tissue. 
During the pre-clinical development of CAB, there were no positive genotox findings. 
Embryo-fetal studies also showed no adverse findings including neural tube defects.  In a 
pre and postnatal study, there were some test article-related decreases in F1 pup survival 
(87.4% vs 98.9% in control) in the highest dose (1000 mg/kg/day) during postnatal days 
1-4.  No findings in the 0, 0.5 and 5 mg/kg/day doses).  
The clinical significance of these finding in humans is unknown. 
Human Data 
Cabotegravir use in pregnant females has not been evaluated and there are insufficient 
human data on the use of CAB + RPV LA during pregnancy to adequately assess a drug-
associated risk of birth defects and miscarriage.  
While there are insufficient human data to assess the risk of neural tube defects (NTDs) 
with exposure to CAB + RPV LA during pregnancy, preliminary findings from an 
unscheduled analysis of a birth outcomes surveillance study conducted in Botswana 
(Tsepamo Study) and presented in May 2018 showed a higher than expected number of 
neural tube defects (NTDs) among newborns whose mothers were exposed to DTG based 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
253 
 
ART at conception.  DTG is a different molecule in the same integrase class of 
medications as CAB. As of May 2018 four cases of neural tube defects were identified in 
426 infants born to mothers who were exposed to DTG-containing regimens from the 
time of conception. In the same study, no infant born to a woman who started DTG 
during pregnancy had a neural tube defect, out of 2,824 women. Updated analysis of 
interim data from the Tsepamo study became available in 2019 and more recently in 
2020. Subsequently, the study team presented an updated analysis, including data through 
to 30 April 2020, at the 23rd International AIDS Society (IAS) Meeting [Zash, 2020].  
 
The latest data from the Tsepamo study included additional data accrued between 1 April 
2019 (the cut-off for the last formal analysis) and 30 April 2020. Over this 13-month 
period, 39,200 additional births were recorded, including 1908 additional exposures to 
DTG at conception. Two additional NTDs were detected in 1908 (0.10%) deliveries to 
mothers taking DTG at conception, compared with six NTDs in 4569 (0.13%) deliveries 
in mothers taking non-DTG regimens at conception, of which five NTDs in 2999 (0.17%) 
deliveries were to mothers taking efavirenz at conception. The incidence in HIV negative 
mothers over the 13-month period was 17/30,258 (0.06%).  
As of the Tsepamo Apr 2020 analysis, seven cases of neural tube defects were reported in 
3,591 deliveries (0.19%) to mothers taking dolutegravir -containing regimens at the time 
of conception, compared with 21 cases in 19,361 deliveries (0.11%) to mothers taking 
non- dolutegravir containing regimens at the time of conception (Prevalence Difference 
0.09%; 95% CI -0.03, 0.30).  Since first analysis, the estimated prevalence of neural tube 
defects with DTG exposure at conception has decreased in magnitude from 0.94% to 
0.19%. In the same study, no increased risk of neural tube defects was reported in women 
who started dolutegravir during pregnancy. Two out of 4,448 deliveries (0.04%) to 
mothers who started dolutegravir during pregnancy had a neural tube defect, compared 
with five out of 6,748 deliveries (0.07%) to mothers who started non-dolutegravir -
containing regimens during pregnancy. 
 
A causal relationship of these events to the use of DTG has not been established.  
The incidence of neural tube defects in the general population ranges from 0.5-1 case per 
1,000 live births. There are insufficient human data on the use of CAB + RPV LA during 
pregnancy to adequately assess a drug-associated risk of miscarriage or birth defects, 
including NTDs.

11.11.3.2. Rilpivirine 
Animal Data 
Rilpivirine was administered orally to pregnant rats (40, 120, or 400 mg/kg/day) and 
rabbits (5, 10, or 20 mg/kg/day) through organogenesis (on Gestation Days 6 through 17, 
and 6 through 19, respectively). No significant toxicological effects were observed in 
embryo-fetal toxicity studies performed with rilpivirine in rats and rabbits at exposures 
15 (rats) and 70 (rabbits) times the exposure in humans at the RHD. In a pre- and 
postnatal development study, rilpivirine was administered orally up to 400 mg/kg/day 
through lactation. No adverse effects were noted in the offspring at maternal exposures 
up to 63 times the exposure in humans at the RHD 
Human Data 
Based on prospective reports to the APR of over 390 exposures to oral rilpivirine-
containing regimens during the first trimester of pregnancy and over 170 during 
second/third trimester of pregnancy, the prevalence of birth defects in live births was 
1.3% (95% CI: 0.4% to 3.0%) and 1.1% (95% CI: 0.1% to 4.0%) following first and 
second/third trimester exposures. 
Available data from the APR show no difference in the overall risk of birth defects for 
rilpivirine compared with the background rate for major birth defects of 2.7% in a U.S. 
reference population of the Metropolitan Atlanta Congenital Defects Program (MACDP) 
In a clinical trial, total oral rilpivirine exposures were generally lower during pregnancy 
compared with the postpartum period. Refer to the current Edurant Prescribing 
Information for additional information on rilpivirine (Edurant Prescribing Information, 
2018). 
11.11.4. 
Clinical Considerations 
11.11.4.1. Exposure 
Lower exposures with oral rilpivirine were observed during pregnancy. Cabotegravir and 
rilpivirine are detected in systemic circulation for up to 12 months or longer after 
discontinuing injections of CAB + RPV LA; therefore, consideration should be given to 
the potential for fetal exposure during pregnancy. 
With the change in volume of distribution associated with pregnancy, drug concentrations 
of CAB and RPV during pregnancy will be assessed in pregnant participants who 
contiune to receive LA therapy while on study. For these participants, plasma PK 
samples of CAB and RPV will be obtained at every study visit for Q8W and Q4W during 
the pregnancy and at the first postpartum LA injection visit. Viral load testing and 
Clinical Chemistry will also be collected at every study visit during the pregnancy and at 
the first postpartum LA injection visit. Additionally, all other scheduled assessments,  
will continue as reflected in as described in the protocol in the Time and Events Table 
(see Section 7.1)

11.11.4.2. Use of Supplements with CAB + RPV LA 
During pregnancy, additional supplements including vitamins, minerals and other 
mediations including OTC meds may be prescribed to the pregnant woman. It is 
important for all female participants who remain in the study to be aware of any potential 
DDIs that may occur with study medications and other agents used during pregnancy. 
11.11.4.2.1. 
Oral Cabotegravir Only 
Antacid products containing divalent cations (e.g., aluminium, calcium and 
magnesium) must be taken at least 2 hours before or at least 4 hours after CAB. 
Concurrent administration of multivitamins is acceptable. 
11.11.4.3. Overall Benefit: Risk Conclusion  
All medications have AE profiles that must be assessed prior to use, allowing for an 
appropriate risk/benefit assessment.  Additional considerations when using CAB + RPV 
LA can be found in the protocol in Section 2.3. 
There is limited data regarding the use of CAB + RPV LA in pregnant females. Based on 
animal data, the use of CAB + RPV LA is not anticipated to increase the risk of adverse 
developmental or reproductive outcomes in humans.  Available data from the APR show 
no difference in the overall risk of birth defects for rilpivirine compared with the 
background rate for major birth defects of 2.7% in a U.S. reference population of the 
Metropolitan Atlanta Congenital Defects Program (MACDP). 
Refer to Section 11.11.3 for additional data. 
The use of CAB + RPV LA during pregnancy may offer unique benefits. It is well 
documented that treatment adherence challenges to oral therapy exists both in the peri-
partum and post-partum periods with LA dosing offering an opportunity to overcome 
such adherence challenges. LA therapy may also help with nausea (50 % mild to 
moderate) or hyperemesis (2%). Female participants on LA dosing who become pregnant 
will have exposures throughout pregnancy due to the long half-life and PK tail of 
CAB/RPV. Pregnant participants who are withdrawn from study and are initiated on an 
alternative oral ART regimen consisting of either 2 or 3 antiretrovirals to protect the life 
of the mother and for the prevention of MTCT, potentially expose the fetus to additional 
ARVs during gestation (in some cases upwards of 5 antiretrovirals). 
In summary, while the 207966 protocol still mandates effective contraception for all 
WOCP, if a woman does become pregnant while on study, a benefit/risk assessment 
between the treating physician and the study participant regarding whether to continue on 
study will be undertaken. Allowing women who become pregnant to stay on study will 
abrogate the need to add additional ART agents to maintain VL suppression if such a 
woman was to be withdrawn from study and LA dosing. 
Given the risk/benefit ratio for CAB + RPV LA dosing in WOCBP, coupled with 
concerns of increasing fetal exposure to several additional antiretrovirals upon participant

withdrawal, pregnant participants will be allowed to remain in the study and continue to 
receive CAB + RPV LA injections, once the new pregnancy ICF addendum is signed by 
the participant.  
11.11.5. 
Study Assessments and Procedures: specific assessments for 
pregnant participants 
Participants who become pregnant while in the study, and who sign the informed consent 
pregnancy addendum may remain in the study and continue to receive CAB + RPV LA.  
Please note: The HIV provider is responsible for HIV care and will collaborate and share 
information with the subject’s obstetric care provider, discuss the subject’s participation 
in this study, the necessary procedures at delivery, to share HIV information, and to 
collect birth and infant outcomes from the subject’s obstetric care provider and/or the 
pediatric health provider for the infant. 
Because obstetric and/or pediatric care will not be specifically provided via this study, the 
subject must also establish appropriate obstetric and pediatric care (including prenatal 
care) per local standard of care (SoC) in parallel.  It will be necessary for the subject to 
provide a release of medical information to facilitate collection of pregnancy and 
pregnancy outcomes by the investigator 
In addition to the asssessments mentioned in this appendix, the rest of the study 
assessments will be conducted in accordance with the protocol, as described in the 
protocol in the Time and Events Table (see Section 7.1) 
11.11.5.1. Safety Assessments 
All pregnant participants who elect to remain in the study will have the following 
samples obtained at each LA injection visit throughout the pregnancy and at the first 
postpartum LA injection visit.  
• HIV-1 RNA 
• Clinical Chemistry 
Pregnancy related complications and diagnoses, and outcomes will be captured as AEs 
and SAEs as outlined in the protocol in section 7.4.3. 
Pregnancy complications (e.g., preeclampsia or eclampsia, prolonged hospitalization after 
delivery, for wound infections etc, seizures) and elective terminations for medical reasons 
must be reported as an AE or SAE.  Spontaneous abortions must be reported as an SAE. 
In the event of a pregnancy loss, after the loss is confirmed the subject may continue to 
receive CAB + RPV LA unless they meet the criteria for confirmed virologic withdrawal.  
They may continue to CAB + RPV LA until study medications are locally approved and 
commercially available or until they no longer receive benefit.  In this case the subject 
must agree to use contraception to avoid a ‘new’ pregnancy (See Appendix 7).

Any SAE occurring in association with the pregnancy brought to the investigator’s 
attention after the subject has completed the study and considered by the investigator as 
possibly related to the study treatment, must be promptly reported to GSK 
11.11.5.2. Pharmacokinetics 
Refer to section 7.5 in the protocol 
All pregnant participants who elect to remain in the study will have the following PK 
samples obtained at each LA injection visit throughout the pregnancy and at the first 
postpartum LA injection visit: 
• Blood samples for evaluation of total CAB (2mL each) and total RPV (2mL 
each) plasma concentrations.  
• Blood sample for evaluation of unbound CAB (9mL each) plasma PK 
concentration. 
. All PK samples will be trough levels and will be collected prior to the scheduled LA 
injection. The pre-dose trough PK sample is to be collected within 15 minutes prior to the 
LA dose, on the day of the study visit.  
For participants pregnant during the Long Term Follow Up phase, plasma concentrations 
of cabotegravir and rilpivirine will be collected as per Section 7.1 Time and Events table. 
Please refer to the SPM for PK sample collection, processing, and shipping instructions. 
The actual date and time of each PK sample collection will be recorded in the eCRF.

Appendix 12: Device Deficiencies: Definition and 
Procedures for Recording, Evaluating, Follow-up, and 
Reporting in Medical Device Studies 
The definitions and procedures detailed in this appendix are in accordance with ISO 
14155 and the European Medical Device Regulation (MDR) 2017/745 for clinical device 
research, and the US Food and Drug Administration (FDA) combination product 
reporting rule, 21 CFR 4, Subpart B. 
Both the investigator and the sponsor will comply with all local medical device reporting 
requirements for medical devices. 
The detection and documentation procedures described in this protocol apply to all 
medical devices used in the study (see Section 6.14 for the list of medical devices). 
11.12.1. 
Definition of Device Deficiency 
Device Deficiency Definition 
• 
A device deficiency is an inadequacy of a medical device with respect to its 
identity, quality, durability, reliability, safety, or performance. Device deficiencies 
include malfunctions, use errors, and inadequacy of the information supplied by 
the manufacturer. 
11.12.2. 
Recording and Follow-Up of AE and/or SAE and Device 
Deficiencies 
AE, SAE and Device Deficiency Recording 
• 
When adevice deficiency occurs, with or without an associated AE/SAE, it is the 
responsibility of the investigator to review all applicable documentation (e.g., 
hospital progress notes, laboratory reports, and diagnostics reports) related to the 
event. 
• 
The investigator will then record all relevant device deficiency information on the 
appropriate form. If applicable, any associated AE or SAE will be documented in 
the participant’s medical records, in accordance with the investigator’s standard 
clinical practice.There may be instances when copies of medical records for 
certain cases are requested by the sponsor. In this case, all participant identifiers, 
with the exception of the participant number, will be redacted on the copies of the 
medical records before submission to the sponsor. 
• 
The investigator will attempt to fully describe the device deficiency and provide 
details on any treatment provided.  
• 
For device deficiencies, it is very important that the investigator describe any 
corrective or remedial actions taken to prevent the deficiency’s recurrence. 
o A remedial action is any action other than routine maintenance or servicing of 
a medical device where such action is necessary to prevent the recurrence of a 
device deficiency. This includes any amendment to the device design to

prevent recurrence. 
Assessment of Intensity of associated AE/SAEs 
• If an AE or SAE is associated with a device deficiency, the investigator will make an 
assessment of intensity for each AE or SAE as outlined in Section 7.4.3 
Follow-up of device deficiency 
• 
The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the 
sponsor to elucidate the nature of the device deficiency and any associated AE or 
SAE as fully as possible 
• 
New or updated information regarding the device deficiency will be recorded in the 
originally completed medical device deficiency report form. 
• 
If there is an associated SAE with the device deficiency, the investigator will submit 
any updated SAE data to GSK within 24 hours of receipt of the information.

Non-inferiority, Open-label Study Evaluating the Efficacy, Safety, and Tolerability of 
Long-acting Cabotegravir Plus Long-acting Rilpivirine Administered Every 8 Weeks or 
Every 4 Weeks in HIV-1-infected Adults who are Virologically Suppressed (ATLAS-
2M), further referred to as A2M. 
 
Sub-study Protocol Amendment Title: Sub-sudy to the A2M study to Evaluate the 
Pharmacokinetics, Tolerability and Efficacy of Cabotegravir and Rilpivirine Long-Acting 
Injections Following Intramuscular Administration in the Vastus Lateralis Muscle (thigh) 
in HIV-infected Adult Participants who have Received at Least Three Years of Gluteal 
Injections in the A2M Study. 
 
11.13.1. 
Sub-study Amendment Background 
Cabotegravir/rilpivirine (CAB/RPV) long acting (LA) has been approved for the 
treatment of HIV-1 infection as a complete regimen in adults to replace the current 
antiretroviral regimen in many geographical regions of the world including the United 
States, Canada, Europe and Australia with additional countries approaching regulatory 
approval. CAB/RPV LA is administered via gluteal injections for monthly or every two 
months dosing for clinic-based administration by a Health Care Provider (HCP).  As 
more patients are experiencing this new treatment paradigm, it is becoming apparent that 
HIV stigma and issues surrounding HIV disclosure, while improved, have not totally 
been eradicated.  As more HIV infected individuals opt for LA therapy to control their 
HIV infection, many patient groups and other activist communities are requesting 
continued research and development in alternative injection sites. These measures may 
improve overall treatment compliance for patients with difficulty adhering to monthly or 
every other month office visits and may improve any residual stigma that patients may 
still be experiencing during their engagement with various healthcare systems. 
 
An ongoing Phase 1, healthy volunteer open-label study (208832) is evaluating the 
pharmacokinetics (PK) and tolerability of cabotegravir and rilpivirine long-acting 
injections following intramuscular administration in the vastus lateralis muscle (further 
referred to as thigh) in 15 study participants (n= 9 male, n=6 female; BMI (kg/m2)  
median 30.3). All subjects received a 4-week oral lead in (OLI) with daily cabotegravir 
30 mg and rilpivirine 25 mg, and after a two week wash out, 14 participants received 
single 600 mg CAB LA and 900 mg RPV LA injections. One participant was withdrawn 
after the OLI phase and before injection due to confirmed pregnancy. 
 
PK sampling for measurement of plasma CAB and RPV in this on-going Phase 1 study 
was performed at the following timepoints: D1, 2, 4, 5, 7, 8, 10, 15, 17 , 22, 28 (week 4) 
post injection with longer term PK evaluations also obtained at weeks 8, 12, 24, 36, and 
52 post the single CAB/RPV injections. Safety and tolerability data through week 12

demonstrated good overall tolerability with all 14 subjects receiving injections 
experiencing ISRs of limited duration (mostly pain at the injection site with a few 
subjects experiencing erythema and induration at the injection site). Of the 14 ISRs, 13 
were judged by the investigator as mild and one considered moderate (pain and erythema 
at the injection site). Additionally, one subject with mild ISR of pain also had bilateral 
hip pain after injection and a mild elevation of AST (84 UL/L) and ALT (74 UL/L). This 
subject had a confirmed diagnosis of COVID-19 infection raising the possibility that the 
constellation of signs and symptoms may be secondary to infection with SARS-COV-2. 
Overall, laboratory abnormalities were minimal with mild and transient ALT elevations 
noted for some subjects. All ALT elevations returned to baseline levels during the study 
except for one subject who continued with fluctuating ALT elevations, with the highest 
value reported for ALT of  97 UL/L and for AST of 106 UL/L.  
 
PK data through 12 weeks post injections was evaluated and considered supportive of 
further studies of thigh administration in HIV-infected individuals. When compared to 
the simulated CAB plasma concentrations following gluteal administration of CAB LA 
600 mg (accounting for covariates), observed CAB plasma concentrations following 
600 mg of CAB LA to the lateral thigh were slightly higher than the predicted at 1-week 
(~Cmax) and 4-weeks post injection but similar to the predicted at 8-weeks post 
injection. These differences may have resulted from slightly faster absorption via thigh 
administration than gluteal administration for CAB LA. RPV plasma concentrations 
following 900 mg of RPV to the lateral thigh were consistent with predictions following 
RPV gluteal administration.

Covariates were resampled 1000 times from the participants in the thigh PK study (n=14), 
generating 1000 virtual subjects. Individual PK parameters of the virtual subjects were calculated 
using subject-specific covariates and using the population parameter estimates including residual 
variability, subject-specific NONMEM inter-individual errors (ETAs) sampled from the distributions 
that are decided by the estimated variance-covariate matrix of between-subject variability from 
the final PopPK model. Concentration-versus-time profiles of the virtual subjects were calculated 
using the individual PK parameters of the virtual subjects following a single CAB LA injection of 
600 mg. Median and 5th and 95th percentiles of the simulated concentration-versus-time profiles 
of the virtual subjects were calculated and plotted.

Sub-study Amendment rationale 
Data through week 12 from the Phase 1 study, as described above, suggest well tolerated 
thigh injections with CAB and RPV PK concentrations similar between thigh and gluteal 
injections. This study provides the evidence  to evaluate thigh injections  in HIV-infected 
individuals  already receiving either  Q4W or  Q8W dosing of CAB/RPV LA. Instead of 
designing a separate study, A2M will be amended to allow an assessment of thigh 
injections as an alternative injection site than what is currently allowed in the prescribing

information to evaluate the PK parameters, safety, tolerability and virologic response in 
HIV-1 infected participants receiving CAB and RPV LA. 
 
This sub-study will assess the comparability of CAB and RPV PK (and other parameters) 
following gluteal and thigh injections. Absorption of CAB following injection into an IM 
site is described as a first order process with an absorption rate constant, KA LA. This 
absorption rate constant is the model parameter that is most sensitive to alterations in 
physiology and drug administration; the factors of gender, BMI and needle length all 
influence CAB absorption kinetics and are covariates for the parameter KA LA. Plasma 
trough concentration (Ctau) is the exposure parameter most associated with 
cabotegravir efficacy with an identified 5th percentile of population exposure used to 
determine efficacious regimens and interventions. Importantly, CAB has a wide 
therapeutic index where despite approximately 6-fold difference in CAB ka values across 
the population (including a 2-fold mean difference between males and females) there is 
no difference in Phase 3 efficacy.   
 
The main PK parameters of interest include Ctau, concentrations post dose [~Cmax], and 
AUC (0-Ctau). CAB and RPV PK parameter will be evaluated by comparing thigh 
injection with  gluteal injection using the ratio of the geometric mean of thigh injection to 
the geometric mean of the gluteal injection for a PK parameter within each treatment arm 
(Q8W, Q4W) and each analyte (CAB, RPV).  No formal statistical hypotheses are to be 
tested,   and the sample size was selected mainly based on the precision of the geometric 
mean ratio estimate (thigh injection vs gluteal injection) and the data sufficiency to assess 
the safety parameters within 16 weeks of thigh injection phase.  
Moreover, additional safety and tolerability data following thigh injections for both 
regimens will also be collected to better characterise the safety/tolerability profile of IM 
injections to the lateral thigh.   
 
The study’s main objective is to assess the comparability of PK  between thigh vs gluteal 
injections in HIV-1 infected participants to support at home IM strategy for LA self-

11.13.5.3. Sub-study: Value Evidence and Outcomes 
Health outcomes assessments will be conducted according to the Time and Events Table 
(Section 11.13.5). Assessments are recommended to be administered with a paper 
instrument at the beginning of the visit (except for NRS which is performed after the 
injections) prior to collection of blood for analysis and other scheduled assessments. 
There will be four health outcome measurements that will be administered during the 
sub-study including Numerical Rating Scale (NRS), HIVTSQc, HIVTSQs and a 
Preference questionnaire.  
Numerical Rating Scale (NRS) 
A numeric rating scale was used to assess the level of pain experienced following 
injections with CAB + RPV. The scale contains one item and the response scale is 
ranging from 0= “no pain” to 10= “extreme pain”. The NRS was used to assess 
maximum level of pain on the day of the injection as well as maximum level of pain one 
week following injection. NRS questionnaires should be collected 30 to 60 minutes post 
injection. 
HIV Treatment Satisfaction Questionnaire (HIVTSQ) 
HIVTSQ is a self-completion measure specifically designed to measure treatment 
satisfaction in PLHIV. It explores multiple aspects of treatment satisfaction including 
side effects, treatment demands, convenience, flexibility and understanding of HIV.  
There are two versions of this questionnaire: HIVTSQs and HIVTSQc.  
HIVTSQs (status version) is needed to measure absolute level of satisfaction while the 
HIVTSQ change version (HIVTSQc) was developed to overcome ceiling effects 
associated with HIVTSQs and enhance sensitivity to change by allowing those who were 
optimally (or close to optimally) satisfied at baseline to express even greater satisfaction 
at follow up. The HIVTSQc is assessing the change in patients’ satisfaction between their 
previous and their current treatment within the same group.  
Total score for HIVTSQs ranges from 0-66 and. Higher scores indicate a greater 
satisfaction and a lower score indicate dissatisfaction. Individual score range from 0-6. 
HIVTSQc total score ranges from -33 to 33. A higher score indicate improvement in 
satisfaction with treatment; lower scores indicate a greater deterioration in satisfaction 
with treatment; a score of 0 represents no change. Individual items scores range from -3 
to 3 (-3= much less satisfied now, 3= much more satisfied now).  
Preference Questionnaire 
A preference question was used to assess patients’ preference, and reasons for preference, 
for the thigh injections compared with the gluteal injections. The “Preference” 
questionnaire will include a single item questions evaluating preference of HIV treatment 
and the attributes supporting this preference.

Participants who received CAB LA + RPV LA IM thigh injection every 4 weeks for a 
total of 16 weeks during the Thigh Injection Phase will return to the clinic 4 weeks later  
(7 days) to receive their first IM gluteal injection (at Week 16) of CAB LA (2mL; 
400mg) and RPV LA (2 mL; 600 mg) during the Return to Gluteal Injection Phase. The 
subsequent gluteal injection with CAB LA 400 mg and RPV LA 600 mg will occur 4 
weeks later (7 days) at Week 20. Gluteal injection administered at Week 24 visit will be 
considered part of the parent study. 
The interval between injection visits will be limited to a maximum of 5 weeks.  The 
Medical Monitor must be contacted to discuss individual participant case management if 
the length of time between injections exceeds or is projected to exceed 5 weeks. 
Participants receiving 2M (Q8W) IM injections while on A2M study who enter into the 
Thigh Injection Phase will receive  an intramuscular injection of CAB LA (3 mL; 600 
mg) on one lateral thigh and RPV LA (3 mL; 900 mg) into the opposite lateral thigh on 
day 1 of the Thigh Injection Phase. Subsequent thigh injections with CAB LA 600 mg 
and RPV LA 900 mg will occur every 8 weeks (7 days). 
Participants who received CAB LA + RPV LA IM thigh injection every 8 weeks for a 
total of 16 weeks during the Thigh Injection Phase  will return to the clinic 8 weeks later 
(at Week 16)  to receive their first IM gluteal injection of CAB LA (3mL; 600mg) and 
RPV LA (3 mL; 900 mg) during the Return to Gluteal Injection phase. The subsequent 
gluteal injection with CAB LA 600 mg and RPV LA 900 mg will 8 weeks later (7 days) 
at Week 24. Gluteal injection administered at Week 24 visit will be considered part of the 
parent study. 
The interval between injection visits will be limited to a maximum of 9 weeks.  The 
Medical Monitor must be contacted to discuss individual participant case management if 
the length of time between injections exceeds or is projected to exceed 9 weeks. 
For additional details regarding the Sub-study dosage and administration please refer to 
the Study Reference Manual. 
11.13.6.3. Oral Bridging during the Sub-study 
Given the limited number of thigh injections for both Q4W (4 injections) and Q8W (2 
injections) during the sub-study, any oral bridging will not be allowed in this sub-study.

Sub-study Statistical Considerations and Data Analyses 
11.13.8.1. Statistical Hypotheses 
The primary objective of this sub-study is to evaluate the pharmacokinetics of monthly 
and every 2 months dosing of CAB LA  and RPV LA injections following intramuscular 
administration in the vastus lateralis (thigh) muscle of HIV-1 infected participants

currently enrolled in the A2M study. No formal statistical hypotheses are to be tested. 
Where appropriate, an estimation approach will be taken and point estimates and 
confidence intervals will be constructed for the ratio of the geometric mean of thigh 
injection to the geometric mean of the gluteal injection. 
11.13.8.2. Sample Size Considerations 
No formal sample size calculation has been made. The sample size of 41 subjects per 
treatment arm (Q8W, Q4W) is sufficient to evaluate the geometric mean ratio (thigh 
injection vs gluteal injection) of PK parameters and to assess the safety parameters within 
16 weeks of the thigh injection phase. 
PK parameter comparisons of interest are shown in Table 15.  Each comparison (first or 
last thigh injection vs gluteal injection) will be evaluated separately by treatment arm and 
analyte (CAB, RPV). In the main study, the observed between subject coefficient of 
variation (CVb) for Week 96 trough PK concentrations among overall population ranges 
from 40% to 56%. Conservatively, assuming within subject coefficient of variation is 
56%, it is estimated that the half width of the 90% confidence interval for the geometric 
mean ratios on log-scale will be within 19%. If the point estimate of the ratio of 
geometric means is 1, then the 90% confidence interval will be approximately (0.83, 
1.21) on the original scale.

Table 17 provides probabilities of observing at least one subject with an adverse event 
(AE) at a given true AE rate across a range of sample sizes. The smaller true AE rate, the 
larger sample size is required to observe the AE with a decent probability. In the main 
study, the observed rates for injection site reaction (ISR) AEs and AEs of special interest 
(AESI) during the Maintenance phase varies, ranging from 0% to 79%. At true AE rate of 
0.5%, the sample size of 41 subjects per treatment arm can provide approximately 18% 
probability of observing at least one subject with AE in each treatment arm. In case of 
rare events (e.g. serious AEs) with 0% observed rate, the upper limit of the 1-sided 95% 
clopper-pearson confidence interval is 7.0% with the sample size of 41 subjects.

11.13.8.3. Data Analysis Considerations 
11.13.8.3.1. 
Analysis Populations 
Pharmacokinetic Concentration Population for Thigh PK Sub-study Amendment 
The pharmacokinetic concentration population for this sub-study will consist of all 
participants who received at least one CAB and/or RPV thigh injection and provide at 
least one non-missing CAB and/or RPV plasma concentration value (non-quantifiable 
values will be considered as non-missing values) during the sub-study. 
Pharmacokinetic Parameter Population for Thigh PK Sub-study Amendment 
The pharmacokinetic parameter population for this sub-study will consist of all 
participants who received at least one CAB and/or RPV thigh injection and had at least 
one available PK parameter estimate.  
Intent-to-Treat Exposed Population for Thigh PK Sub-study Amendment  
The ITT-E population for this substudy will consist of all participants who were 
randomized in the main study and received at least one CAB and/or RPV thigh injection. 
Participants will be assessed according to their randomized treatment, regardless of the 
treatment they received. Participants in this population will be included in the efficacy 
and health outcomes analyses. 
Safety Population for Thigh PK Sub-study Amendment 
The safety population for this sub-study will consist of all participants who were 
randomized in the main study and received at least one CAB and/or RPV thigh injection. 
Participants will be assessed according to the actual treatment they received.  
Additional populations may be added and details will be provided in the RAP. 
11.13.8.3.2. 
Planned Analyses 
Only one final analysis is planned after all  subjects have completed the sub-study. 
11.13.8.4. Key Elements of Analysis Plan 
11.13.8.4.1. 
Primary Analysis 
The primary analysis is to compare the thigh injection with the gluteal injection using the 
ratio of the geometric mean of thigh injection to the geometric mean of the gluteal 
injection for a PK parameter within each treatment arm (Q8W, Q4W) and each analyte 
(CAB, RPV). The PK parameter comparisons of interest are described in Table 15 of 
Section 11.13.8.2. No formal hypothesis testings will be performed.  
Following loge-transformation, Cmax, Ctau and AUC(0-tau) will be separately analyzed by 
treatment arm and analyte using a mixed effects model with fixed effect term for type of 
injection (thigh, gluteal) and random effect term for subject. In each model, only subjects 

TMF-13901227 
CONFIDENTIAL 
 
 
 
207966 
 
 
292 
 
with PK parameter estimates from corresponding both thigh and gluteal injections are 
included. For example, in the model for comparing Cmax between the first CAB  thigh 
injection vs gluteal CAB injection for Q8W subjects, only Q8W subjects with Cmax 
estimates from both first CAB thigh injection and CAB gluteal injection are included. 
Point estimates and their associated 90% confidence intervals will be constructed for the 
differences between the thigh injection and the gluteal injection. The point estimates and 
their associated 90% confidence intervals from the log-transformed analysis will then be 
back-transformed to provide point estimates and 90% confidence intervals for the ratios 
between the thigh injection and the gluteal injection on the original scale. 
 
11.13.8.4.2. 
Secondary and Exploratory Analyses 
The proportion of participants with HIV-1 RNA ≥50 c/mL and HIV-1 RNA <50 c/mL 
during the thigh injection phase will be summarized using FDA Snapshot algorithm for 
the ITT-E population for the substudy. Proportion of participants with protocol-defined 
confirmed virologic failures will also be summarized over time. 
The proportion of participants reporting AEs will be tabulated for each treatment group. 
The following summaries of AEs will be provided: 
• Incidence and severity of all AEs 
• Incidence and severity of treatment related AEs 
• Incidence and severity of AEs leading to withdrawal 
• Incidence of SAEs 
• ISR AEs from study drug injections at the event level and subject level, 
separately. 
• Change from baseline (latest non-missing value prior to the first thigh injection) 
in laboratory will be summarized by visit and treatment group.  
• The incidence of observed genotypic and phenotypic resistance to NRTIs and 
INIs, PIs, and NNRTIs will be summarized by treatment arm for subjects meeting 
confirmed virologic failure criteria. 
The health outcomes analyses include analyses of data collected from the following four 
questionnaires, HIVTSQ (both s and c versions), NRS and Preference between thigh and 
gluteal injections. Further details will be provided in the RAP.

recorded during the study.  PK intervals are defined for each arm of the substudy in Table 
16, and the concentration at the end of the interval will also serve as the predose 
concentration for the subsequent interval. The following pharmacokinetic parameters will 
be determined for each interval, as data permit: maximum concentration (Cmax), time to 
Cmax (tmax), area under the plasma concentration-time curve through the end of the 
dosing interval (AUC(0- )), and concentration at the end of the dosing interval (C ).   
 
Plasma concentration data will be summarized descriptively by analyte and treatment 
regimen and presented in graphical and/or tabular form.  Parameters will be summarized 
by analyte and treatment regimen.  Cmax, AUC(0- ) and C  treatment comparisons are 
described above (see Table 15); tmax will not be compared statistically.  All 
pharmacokinetic data (both CAB and RPV) will be stored in the Archives, 
GlaxoSmithKline Pharmaceuticals, R&D.  Additional analyses including modelling, 
simulation and external validation may be performed to assist in the clinical interpretation 
of these data and will be reported separately.

Appendix 14: Protocol Amendment History 
The Protocol Amendment Summary of Changes Table for the current amendment is 
located directly before the Table of Contents (TOC). 
Amendment 5  16-Apr-2021 
Overall Rationale for Amendment 5 
The primary purposes of this amendment are: 
• To allow participants who become pregnant to remain in the study and not be 
withdrawn due to pregnancy. Allowing pregnant participants to continue in the 
study will negate any additional and subsequent fetal exposures to new 
antiretrovirals agents that would occur if the pregnant participant was withdrawn 
from the study and placed on an oral SOC regimen. An Appendix, “Information 
and Guidance for Managing Pregnant Participants” was inserted as Appendix 11, 
and all subsequent appendices were renumbered accordingly.  
• Contraceptive methods have been updated to permit the use of progestogen-only 
implantable and injectable contraceptives without the requirement of a second 
highly effective method. 
• Removal of the optional collection of cord blood and/or breast milk after delivery. 
• Removal of the option for study treatment rechallenge following suspected drug-
induced liver injury (DILI) 
• Clarification of which participants enter the LTFU phase when CAB+RPV LA 
marketed product is locally available. 
• Clarification added: The Reason for Oral Bridgingand Preference questionnaire 
will also be administered at Withdrawal if it occurred at or before Week 152 only 
to participants who received oral bridging during the Maintenance and/or 
Extension Phases. 
• Medical Device reporting requirement added 
• Co-enrolment (Only applicable for South African participants) 
• Clinical and safety references updated 
• Removal of the reference to “randomized study treatment” in Overall design 
sections for alignment with CAB program studies and transition to marketed 
product plan. 
 
Other additional edits were made, for clarity and/or correction.

endpoints and additional assessments in support of the planned secondary analyses have 
been updated for Week 152.  Health outcomes assessments including the HIV-TSQs, 
Accept, and PIN questionnaires are included at Week 152 to gain further insight into 
participant’s long-term treatment experience with Long-acting Cabotegravir Plus Long-
acting Rilpivirine.  The Preference questionnaire will also be administered at Week 152 
only to participants who received oral bridging during the Maintenance and/or Extension 
Phases.  Additional minor clarifications to protocol language have also been

questionnaires; 
• Extend exclusion criterion #28 to also exclude hereditary coagulation and platelet 
disorders such as haemophilia or Von Willebrand Disease; 
• Update exclusion criterion #11 to indicate that CD4+ counts ˂200 cells/L are not 
exclusionary; 
• Offer clarification that withdrawal assessments will be performed for any 
participant who withdraws prematurely from the Maintenance or Extension Phase.  
Additional guidance for participants withdrawing at Week 52 or Week 100 has 
been added;  
• Offer guidance to monitor medications that are dependent on OAT1 and OAT3 
transport upon concomitant exposure with CAB; 
• Specify that 2-hour post-dose ECG should be performed at Day 1 and Week 48 
only for participants receiving CAB LA + RPV LA as it is not required to perform 
2-hour post-dose ECG for those receiving oral CAB + RPV at Day 1; 
• Exclude language that previously indicated hormonal contraception may be 
susceptible to interaction with the study drugs.  The lack of a demonstrated 
interaction with a representative contraceptive supports use of CAB and RPV 
across a broad range of estrogen and progestin or progestin only hormonal 
contraceptives;

Information 
Footnote b from Table 14 has 
been modified to exclude 
language indicating that 
hormonal contraception may be 
susceptible to interaction with the 
study drugs. 
 
Hormonal contraception may be 
susceptible to interaction with the study 
drug, which may reduce the efficacy of 
the contraceptive method. In this case  
b. Two highly effective methods 
of contraception should be 
utilized from 30 days prior to the 
first dose of study medication, 
throughout the study, and for at 
least 52 weeks after 
discontinuation of CAB LA and 
RPV LA. 
CAB and RPV have demonstrated no 
impact on the pharmacokinetics of 
commonly used combined estrogen 
and progestin containing oral 
contraceptives.  Neither CAB nor RPV 
induce or inhibit UGT or CYP enzymes 
which are the predominant metabolic 
routes of elimination for these products. 
The interaction has only been studied 
with levonorgestrel/ethinyl estradiol for 
CAB and norethindrone/ethinyl 
estradiol for RPV. The lack of a 
demonstrated interaction with a 
representative contraceptive supports 
use of CAB and RPV across a broad 
range of estrogen and progestin or 
progestin only hormonal 
contraceptives.

Amendment 01 14-Sep-2017 
Overall Rationale for Amendment #1: The primary purpose of protocol amendment #1 
is to revise the study sample size to randomize approximately 1020 participants including 
510 participants per arm based on a non-inferiority margin of 4% between the CAB LA + 
RPV LA Q8W and Q4W arms.  Assuming the true proportion with HIV-RNA >=50 
c/mL is 3% for the Q8W arm and 2% for the Q4W arm, the revised sample size will 
provide at least 85% power to show non-inferiority at Week 48.  Additional minor 
clarifications and corrections have been added to the protocol text.
