PROTOCOL SYNOPSIS FOR STUDY 205712
Rationale
Cabotegravir (CAB) is a 2-metal binding integrase inhibitor being developed for the 
treatment and prevention of HIV-1 infection as both an oral and long acting (LA) 
injectable nanosuspension.  Rifabutin (RBT) is an antimycobacterial agent used for the 
treatment of tuberculosis as well as for both treatment and prevention of Mycobacterium 
avium intracellulare (MAC) in advanced HIV infection in individuals with low CD4 cell 
counts. RBT is chemically related to rifampin (RIF), the latter is a potent inducer of UDP 
(Uridine 5'-diphospho-glucuronosyltransferase) -glucuronosyltransferases (UGTs) and 
Cytochrome P450 3A4 (CYP3A4).  RBT appears to induce P450 enzymes and UGTs as 
well, although not as potently as RIF. CAB is primarily metabolized via UGT1A1 and 
UGT1A9.  Evidence from the human mass balance and related metabolite identification 
studies suggests that the CYP enzyme involvement in the metabolism of CAB is likely to 
be minimal. Given that RBT is considered to be a weak enzyme inducer, it is anticipated 
that RBT will modestly reduce CAB exposures during concomitant administration.  This 
study is being conducted to evaluate the drug-drug interaction (DDI) potential between 
CAB and RBT to inform dosing strategies for tuberculosis in subjects receiving CAB for 
HIV treatment or prevention.

Treatment Periods and Duration
This study will take place in two treatment periods and a follow-up period.  All subjects 
will undergo a screening visit within 30 days from the first dose of study drug.  The 
overall study duration will be approximately 10 weeks (4 weeks screening, 2 weeks for 
treatment Period 1, 2 weeks for treatment Period 2, and 2 week follow-up period).
Treatment Period 1: Treatment A: CAB 30 mg once daily x 14 days
Treatment Period 2: Treatment B: RBT 300 mg once daily + CAB 30 mg once daily x 14 
days
Type and Number of Subjects

Approximately 15 healthy adult subjects will be enrolled to ensure that 12 subjects 
will complete dosing and critical assessments.  

If subjects prematurely discontinue the study, additional replacement subjects may 
be enrolled and assigned to the same treatment sequence at the discretion of the 
Sponsor in consultation with the investigator.
Analysis
No formal hypothesis will be tested. An estimation approach will be used to evaluate the 
effect of RBT on CAB PK parameters. Point estimates and corresponding 90% 
confidence intervals (CIs) will be constructed for the comparisons of interest 
(test:reference).

INTRODUCTION
2.1.
Study Rationale
Cabotegravir (CAB) is a 2-metal binding integrase inhibitor being developed for the 
treatment and prevention of Human immunodeficiency virus-1 (HIV-1) infection as both 
an oral and long acting (LA) injectable nanosuspension. 
Tuberculosis (TB)/HIV co-infection is common and both conditions often need to be 
treated simultaneously. RIF is a backbone component of TB treatment regimens and is a 
potent inducer of UDP-glucuronosyltransferases (UGTs) and Cytochrome P450 3A4 
(CYP3A4).  CAB is primarily metabolized via UGT1A1 and UGT1A9. Evidence from 
the human mass balance and related metabolite identification studies suggests that the 
CYP enzyme involvement in the metabolism of CAB is likely to be minimal. A reduction 
in CAB serum concentrations due to drug-drug interaction with RIF could lead to a risk 
of treatment failure and the emergence of HIV drug resistance. RIF increased CAB oral 
clearance 2.4-fold and reduced CAB AUC(0- τ)) and terminal phase t1/2 by 59% and 
57%, respectively. RIF had no effect on CAB Cmax. Therefore, co-administration of RIF 
with oral CAB 30mg once daily is not recommended [Ford, 2016].  
RBT is an alternative anti-mycobacterial agent used for the treatment of tuberculosis.  
RBT is chemically related to RIF and is considered a weaker enzyme inducer of UGTs 
and CYP3A as compared to RIF.  The effect of RBT on the PK of CAB has not been 
studied to date. Raltegravir (RAL) is an integrase inhibitor that is also primarily 
metabolized via UGT1A1.  RAL area under the concentration-time curve over 12 hours
(AUC[0-12]) increased by 19% while minimum observed concentration (Cmin) 
decreased by 20% during concurrent RBT administration [Brainard, 2011].  Dolutegravir 
(DTG), another marketed HIV integrase inhibitor, is primarily metabolized via UGT1A1 
with a minor CYP3A component.  Following co-administration of DTG 50 mg once daily 
with RBT 300 mg once daily, DTG AUC(0-) was unchanged [GMR (90% CI) 0.95 
(0.82, 1.10)], Cmax was increased 15% [GMR (90% CI) 1.15 (0.97 ,1.36)], and Cwas 
decreased 30%  [GMR (90% CI) 0.70 (0.57 ,0.87)], [GlaxoSmithKline Document 
Number RM2008/00856/00 ITZ111839 ; Ford, 2013]. Based on RBT drug-drug 
interaction (DDI) data with RAL and DTG, a significant DDI between CAB and RBT is 
not expected.  Because CAB does not induce or inhibit RBT metabolizing enzymes, the 
impact of CAB on RBT PK will not be evaluated in this study. 
This DDI study will evaluate the impact of RBT on the pharmacokinetics of CAB.  The 
results of this study will inform dosing strategies for the management of tuberculosis in 
patients receiving CAB for HIV treatment or prevention
2.2.
Brief Background
Tuberculosis (TB) is surpassed only by human immunodeficiency virus (HIV) as a cause 
of infectious disease-associated deaths worldwide [Frieden, 2003]. In 2012, 1.1 million 
of an estimated 8.6 million people who developed TB worldwide were HIV-positive 
[World Health Organization, 2014]. Given that the yearly incidence of TB is 10% in 
HIV-infected individuals, concomitant treatment for TB is common [Maartens, 2007].  

2016N269788_02
CONFIDENTIAL
205712
13
Increasingly, the two diseases will be treated concurrently in co-infected individuals.  
Two recent studies evaluating the optimal timing for initiation of highly active 
antiretroviral therapy (HAART) in subjects requiring treatment for active TB 
demonstrated a survival benefit for treating HIV during TB treatment rather than waiting 
until after TB treatment completion [Abdool, 2010a; Abdool, 2010b].  However, co-
treatment is complex and difficult owing to drug-drug interactions, immune 
reconstitution inflammatory syndrome, and overlapping toxicities [McIlleron, 2007].
Although TB is a global issue, the geographic distribution of cases is drastically 
disproportionate.  The spread of HIV and multidrug resistance has fuelled the TB 
epidemic, and in less-developed countries, TB is the most common cause of death in 
HIV-infected patients [Corbett, 2003].  Ninety-five percent of all TB cases and 98% of all 
TB deaths occur in developing countries.  Only 22 high-burden countries (HBCs) account 
for 80% of the global TB burden, with half of these countries located within Asia.  In 
Africa, 40 countries have an estimated TB prevalence rate greater than 100/100,000 
compared to the estimated prevalence rate of <5/100,000 in the United States [U.S. 
Department of Health and Human Services, 2014].  
Currently, rifamycins serve as the cornerstone of TB therapy because of their unique 
sterilizing activity. RIF (rifampicin), the most commonly-used rifamycin, is a semi-
synthetic rifamycin derivative that is highly active against mycobacteria, most gram-
positive bacteria, and some gram-negative bacteria. It is bactericidal for both 
intracellular and extracellular microorganisms. By inhibiting prokaryotic 
deoxyribonucleic acid (DNA) -dependent ribonucleic acid (RNA) polymerase, it 
suppresses the early elongation of the nucleotide chain in RNA synthesis.  RIF is a potent 
inducer of a number of hepatic enzymes involved in the metabolism of drugs and some 
hormones, including UGTs and CYP450 enzymes [Venkatesan, 1992].  Significant 
enzyme induction from RIF limits concurrent use with many antiretroviral agents, 
therefore RBT may be an alternative due to its weak enzyme induction potential.  Most 
antiretrovirals can be co-administered with RBT without dose adjustment, including the 
integrase inhibitors, raltegravir and dolutegravir, however, enzyme induction or inhibition 
by non-nucleoside reverse transcriptase inhibitors and boosted protease inhibitors, require 
dose modification of RBT in some cases [Yapa, 2016]. 
As of October 18 2016, the efficacy, safety, and PK of CAB have been evaluated in 19 
(15 completed, 2 concluded and 2 ongoing) Phase I/IIa ViiV sponsored clinical trials with 
oral CAB and CAB LA. Subjects have been exposed to single oral doses of CAB 
ranging from 5-150 mg and repeat once daily doses of 30 mg for 10-28 days in duration.
There have been no deaths or drug-related SAEs. There were no clinically significant 
trends in lab events, ECG, or vital sign changes, or QTcF >500 msec or QTcF change 
from baseline >60 msec. Refer to the Investigators Brochure (IB) for additional 
information.

Treatment Periods and Duration
Subjects will undergo a screening visit within 30 days of the first dose of study drug, 
followed by two treatment periods and a follow-up period. 
Subjects will undergo clinical safety assessments and serial PK assessments at time-
points specified in Section 7.1, Time and Events table of the protocol. 
Period 1  
Eligible participants will be admitted to the unit on Day -1.  
On Day 1, following completion of the required pre-dose measurements, the investigator 
or authorized study unit personnel will administer a single oral dose of 30 mg CAB to 
each subject in the unit.
Subjects will be dispensed a bottle of CAB to be taken at home on Days 2-12 and 
discharged from the unit. Subjects will be provided with a subject diary to document 
daily recordings of dosing occurring outside of the unit.  Subjects will be re-admitted to 
the unit in the morning on Day 13. Prior to dosing, a CAB PK sample will be obtained, 
and then the subjects will receive a single 30 mg dose of CAB on Day 13 and remain in 
the unit overnight.  On Day 14, following an overnight fast of at least 6 hours, subjects 
will receive a single 30 mg dose of CAB with serial CAB PK samples collected pre-dose 
and through 24 hours after dosing up to Day 15.  There will be no washout between 
Period 1 and Period 2.
Period 2
On Day 15 following the completion of the required Day 14 safety assessments and PK 
collection, subjects will proceed to Period 2, where site staff will administer a single dose 
of RBT 300 mg and a single dose of CAB 30 mg in the unit. Subjects will be discharged 
and dispensed a bottle of RBT and a bottle of CAB to be taken at home on Days 16-20. 
Subjects will be provided with a subject diary to document daily recordings of home 
dosing. In the morning of Day 21, subjects will bring their bottle of RBT and bottle of 
CAB for observed dosing in the unit and safety assessments as an outpatient visit.   
Following these procedures, subjects will be discharged with their supply of CAB and 
RBT and instructed to take their daily doses of study medications at home in the 
mornings of Days 22 through 25. On Day 26, subjects will return to the unit for a pre-
dose PK collection and observed dosing as an outpatient visit and then be discharged 
home. On Day 27, subjects will be re-admitted to the unit for a pre-dose PK collection, 
observed dosing, and safety assessments then remain in the unit overnight. In the 
morning of Day 28 following an overnight fast of at least 6 hours, subjects will receive a 
single dose of RBT and a single dose of CAB in the unit with serial CAB PK samples 
collected pre-dose and through 24 hours after dosing up to Day 29. Subjects will be 
discharged from the unit on Day 29 after the final assessment is completed.  Subjects will 
complete a follow-up visit ~ 10-14 days after the last 30 mg oral dose of CAB.

At the follow-up visit, laboratory safety assessments (including pregnancy test for 
females of childbearing potential) will be performed, and vital signs together with a 
12-lead ECG will be obtained.

Type and Number of Subjects

Approximately 15 healthy adult subjects will be enrolled to ensure that 12 subjects 
will complete dosing and critical assessments.

If subjects prematurely discontinue the study, additional replacement subjects may be 
allocated and assigned to the same treatment sequence (A then B) at the discretion of 
the Sponsor in consultation with the investigator.
4.4.
Design Justification
This open-label, fixed sequence, cross-over design is well-established for evaluation of 
drug-drug interaction potential of a perpetrator drug (e.g., RBT) to affect the 
pharmacokinetics of a victim drug (e.g., CAB).  Conducting the study in a fixed sequence 
with daily administration of CAB 30 mg/day for 14 days and then assessing CAB PK 
over 24 hours after the Day 14 dose of CAB will enable characterization of CAB PK by 
itself.  This will avoid the possibility for any inductive effect caused by RBT dosing prior 
to oral administration of CAB alone, as would be the case if the study treatments were to 
be randomized.  Then, in the second treatment period, oral co-administration of RBT 
300 mg once daily and CAB 30 mg once daily for 14 days with the assessment of CAB 
PK over 24 hours after the Day 28 dosing of CAB and RBT will facilitate assessment of 
CAB PK in the presence of RBT at steady-state to observe the likely maximum inductive 
impact of RBT. 
The study is subject to the appropriate regulatory approval and Ethics Committee 
approval, and will be listed on the website ClinicalTrials.gov.  No blinding or placebo 
control will be used, as these are not necessary for the purposes of this study.
4.5.
Dose Justification
A CAB 30 mg single dose was selected for this study as it is the oral induction dose that 
is currently under investigation in the ongoing Phase 2b treatment studies [Protocols 
GlaxoSmithKline Document Number 2012N134026_01,  GlaxoSmithKline Document 
Number 2013N168152_04, 200056] and is the oral induction dose taken into the Phase 3 
studies (the FLAIR and ATLAS studies).  Additionally, for PrEP studies in healthy, 
uninfected subjects, the 30 mg oral dose has been selected for oral lead-in therapy prior to 
injectable dosing in the completed ECLAIR study [Protocol GlaxoSmithKline Document 
Number 2013N184048_01, 201120 and the DAIDS Document ID: 11964 HPTN 077, 
2014 . In two oral relative bioavailability studies [GlaxoSmithKline Document Number 
2012N136689_00, LAI116585 and GlaxoSmithKline Document Number 
2013N165475_00, LAI117020], CAB AUC(0-) was well-estimated with 168 hrs of 
sampling following single dose CAB 30 mg (sodium salt tablet formulation). For these 
two studies, geometric mean AUC(0-) values were 174g*h/mL and 141g*h/mL, and 
Cmax values were 4.24 g/mL and 3.70 g/mL. Assuming a maximal induction effect by 

2016N269788_02

205712
17
RBT of 70-80% reduction, CAB exposure may approximate that of a 5-10 mg oral dose, 
the PK for which has also been well-characterized following single dose administration. 
RBT 300 mg once daily was selected for this study not only for its role as an alternative 
rifamycin for anti-tuberculosis therapy but also because it is the recommended dose for as 
it is the recommended dose for the prevention of disseminated Mycobacterium avium 
complex (MAC) in patients with advanced HIV infection (CD4+ cell count  <200/mm3 
with an AIDS defining diagnosis, or CD4+ cell count  <100/mm3 without an AIDS 
defining diagnosis). The terminal half-life of RBT is approximately 38 hours. Enzyme 
induction by RBT has been demonstrated to occur within 7 days of therapy and auto-
induction of its own metabolism has been demonstrated to occur within 10 days in 
healthy volunteers [Perruca, 1988].  RBT 300 mg (two 150 mg capsules) once daily will 
be administered for 14 days with CAB 30 mg (one 30 mg tablet) once daily for 14 days in 
Treatment Period 2 to ensure that the maximal inductive effect of RBT is achieved. 
The duration of dosing in this study was chosen partly based on scientific convention 
with similar P1 drug-drug interaction studies and particular to this protocol, because of 
the importance of achieving a steady state concentration of study drug (CAB) before PK 
analyses of CAB are performed during Period 1 of the study. Similarly, in Period 2 of the 
study, a similar rationale for duration of 14 days applies to the combination of CAB and 
RBT as well. Oral CAB has a terminal phase elimination t½ of approximately 40 hours 
and reaches steady state by 10-12 days of once daily administration, supporting 14 days 
of dosing in this study [GlaxoSmithKline Document Number 2012N136689_00, 
LAI116585]. Before obtaining PK assessments, both CAB and RBT need to reach steady 
state and 14 days is sufficient time for that to occur.

Drug Induced Liver Injury (DILI)
A small proportion of participants in the 
CAB program to date (total exposure 
approximately 1289 as of 01 October 2016) 
have developed transaminitis (elevated liver 
transaminases characterised by predominant 
alanine aminotransferase [ALT] elevation).  
In some of these participants, transient 
transaminitis was explained by acute 
hepatitis C infection whilst a small number 
of others did not have alternative 
explanations, suggesting a mild form of 
DILI without hepatic dysfunction which 
resolved upon withdrawal of treatment with 
CAB. 
Of the five participants with possible or 
probable cases of DILI identified in Phase 2 
studies, four participants were receiving oral 
CAB and one participant developed 
probable DILI following CAB LA or 
Placebo LA administration.  
Exclusion criteria as described in 
Section 5.2 will prohibit participants 
with significant liver impairment based 
on prior medical history and screening 
liver chemistry including transaminases 
(ALT and Aspartate aminotransferase
[AST]). 
Liver transaminases (ALT and AST) 
will be closely monitored throughout 
this study (refer to Time & Events 
Table) and the liver chemistry stopping 
criteria will be adopted as described in 
Section 5.4.2 of this protocol. 
All instances of liver transaminase 
elevations of Grade 2 and above will be 
followed to resolution.  Participants 
withdrawn from CAB treatment due to 
meeting liver chemistry stopping criteria 
will be regularly monitored both 
clinically and using liver chemistries to 
determine progress towards resolution of 
the liver event.

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, there is a 
theoretical risk of systemic or severe 
hypersensitivity reactions with or without 
hepatic symptoms. 
Clinical assessments, laboratory tests 
(including liver transaminases) and vital 
signs will be performed throughout this 
study (refer to Time & Events Table).  
Results from these assessments may aid 
early detection of HSR.
Oral CAB will be withdrawn 
immediately for cases with suspected 
HSR. Any HSR reactions that occur 
would be managed supportively.

Risk Assessment-Rifabutin
Adverse reactions identified through post-marketing surveillance by system organ class 
(SOC) include: blood cell disorders (agranulocytosis, lymphopenia, granulocytopenia, 
neutropenia, leukopenia, and thrombocytopenia), immune system disorders 
(hypersensitivity, bronchospasm, rash, and eosinophilia), and gastrointestinal disorders 
(Clostridium difficile colitis/ Clostridium difficile associated diarrhea). Pyrexia, rash and 
other hypersensitivity reactions such as eosinophilia and bronchospasm might occur, as 
has been seen with other anti-bacterials. A limited number of skin discolorations have 
been reported. Hypersensitivity to rifamycins has been reported including flu-like 
symptoms, bronchospasm, hypotension, urticaria, angioedema, conjunctivitis, 
thrombocytopenia or neutropenia. See below for the Rifabutin risk assessment and 
mitigation strategy for this protocol.
Neutropenia: Neutropenia is commonly experienced in patients receiving RBT and 
rapidly resolves with discontinuation of RBT.  Subjects will have frequent hematology 
laboratory monitoring and the neutropenia stopping rule is in place, see Section 5.4.4.
Uveitis: Subjects will be followed for development of ocular AEs since RBT has been 
associated with this complication, although it is rare when administered as 300 mg/day. 
Uveitis can develop from 2 weeks to more than 7 months after initiation of RBT 
treatment [Tseng, 1995]. Discontinuation of RBT or dose reduction generally results in 
resolution of uveitis and complete recovery of visual acuity is typical with drug 
withdrawal and topical treatment. Subjects with evidence of new ocular symptoms 
consistent with uveitis (eye pain, eye redness, light sensitivity, blurriness or change in 
vision, that is not attributed to allergic, infectious (bilateral viral/bacterial conjunctivitis 
or HSV keratitis), acute angle-closure glaucoma, corneal abrasions, scleritis, or secondary 
to trauma including intraocular foreign body will be discontinued from study treatment, 
and referred to ophthalmology for evaluation and appropriate treatment. Refer to Ocular 
stopping criteria, Section 5.4.1
Hypersensitivity Reaction (HSR): Clinical assessments, laboratory tests (including liver 
transaminases) and vital signs assessments will be performed throughout this study (refer 
to Time & Events Table).  Results from these assessments may aid early detection of 
HSR. RBT will be withdrawn immediately for cases with suspected HSR. Any HSRs that 
occur would be managed supportively.

Uveitis
While RBT can cause 
uveitis, the condition occurs 
more often with higher 
doses than what is being 
evaluated in this study 
(300 mg).                               

While the likelihood of uveitis is low with the 
dose used in 205712, patients with a current of 
past history of uveitis will be excluded from this 
study (exclusion criteria #7). Also, a uveitis 
stopping criteria (Section 5.4.1) has been added 
to the protocol and subjects who develop eye 
pain, eye redness, blurry vision or 
photosensitivity not attributed to allergic, 
infectious (bilateral viral/bacterial conjunctivitis 
or HSV keratitis), acute angle-closure glaucoma, 
corneal abrasions, scleritis, or secondary to 
trauma (including intraocular foreign body) will 
be discontinued from study treatment, and 
referred to ophthalmology for evaluation and 
appropriate treatment. Medical monitor will be 
notified if a patient develops any signs or 
symptoms of acute uveitis as noted above.
Hypersensitivity 
Reaction (HSR)
While not commonly 
described, HSR can occur 
with the administration of 
any medicinal product 
including RBT
Clinical assessments, laboratory tests (including liver 
transaminases) and vital signs will be performed 
throughout this study (refer to Time & Events

Adverse Events of Special Interest
Seizure
Three cases of seizures have occurred in the cabotegravir programme cumulatively 
through 01 October 2016. Two of the cases occurred in HIV uninfected subjects with a 
prior history of seizure and one case involved a subject in study 200056 
[GlaxoSmithKline Document Number 2013N168152_04, 200056] with circumstantial 
and anecdotal evidence of illicit drug use. Overall, there is not convincing evidence that 

2016N269788_02
CONFIDENTIAL
205712
22
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 close monitoring in all studies. Subjects with recent history of, or recent 
treatment for seizure will be excluded from study participation.
4.6.4.
Benefit Assessment
Subjects participating in the study will not receive any clinical benefit, but will be 
compensated for their time and participation.
4.6.5.
Overall Benefit: Risk Conclusion
Taking into account the measures taken to minimize risk to subjects participating in this 
study, the potential risks identified in association with CAB and RBT are justified by the 
anticipated benefits that may be afforded to subjects with HIV and to those healthy 
subjects who may benefit from CAB as a preventative agent for acquisition of HIV.


In cases where the subject is deemed ‘lost to follow up’, the investigator or 
designee must make every effort to regain contact with the subject (where 
possible, 3 telephone calls and if necessary a certified letter to the subject’s 
last known mailing address or local equivalent methods). These contact 
attempts should be documented in the subject’s medical record. 

Should the subject 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 subject 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, behavioural or 
administrative reasons. If a subject withdraws from the study, he/she may request 
destruction of any samples taken, and the investigator must document this in the site 
study records. 
During the treatment phase, pre-specified reasons for discontinuing a participant from the 
study (or, discontinuing administration of study product and continuing safety 
evaluations) may include:

Pregnancy (please see Section 7.3.2)


determine eligibility for and discontinuation from the study.  This formula may not 
be changed or substituted once the subject has been enrolled.
Fridericia’s QT correction formula must continue to be used for that subject for all QTc 
data being collected for data analysis.  Safety ECGs and other non-protocol specified 
ECGs are an exception.  

The QTc should be based on single or averaged QTc values of triplicate 
electrocardiograms obtained over a brief (e.g., 5-10 minute) recording period and 
then use the averaged QTc values of the 3 ECGs to determine whether the subject 
should be discontinued from the study.  
A subject that meets either bulleted criterion below will be withdrawn from the study.

Neutropenia Stopping Criteria
Subjects with an absolute neutrophil count (ANC) less than 1 x10^9/L will be 
discontinued from study treatment. The presence of ANC less than 1 x10^9/L and a 
single measured temperature of >38.3 oC or a sustained temperature of ≥ 38 oC (100.4 oF) 
for more than one hour refers to neutropenic fever and subjects should be referred for 
urgent evaluation and appropriate management.
5.4.5.
Uveitis Stopping Criteria
Subjects who develop eye pain, eye redness, blurry vision or photosensitivity not 
attributed to allergic, infectious (bilateral viral/bacterial conjunctivitis or herpes simplex 
virus [HSV] keratitis), acute angle-closure glaucoma, corneal abrasions, scleritis, or 
secondary to trauma (including intraocular foreign body) will be discontinued from study 
treatment, and referred to ophthalmology for evaluation and appropriate treatment. 
Medical monitor should be notified if a patient develops any signs or symptoms of acute 
uveitis as noted above.
5.5.
Subject and Study Completion
A completed subject is one who has completed all phases of the study including the 
follow-up visit.
The end of the study is defined as the last subject’s last visit.

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 subject as per the protocol design. Study treatment may 
therefore refer to the individual study treatments or the combination of those study
treatments.

Preparation/Handling/Storage/Accountability
No special preparation of study treatment is required.

Only subjects enrolled in the study may receive study treatment and only authorized 
site staff may supply or administer study treatment.  All study treatments must be 
stored in a secure environmentally controlled and monitored (manual or automated) 
area in accordance with the labelled storage conditions with access limited to the 
investigator and authorized site staff. 

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).

Further guidance and information for final disposition of unused study treatment 
are provided in the Study Reference Manual (SRM).

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.
6.6.
Compliance with Study Treatment Administration
When the individual dose for a subject is prepared from a bulk supply, the preparation of 
the dose will be confirmed by a second member of the study site staff. 
When subjects 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 source documents.  The dose of study 
treatment and study subject 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.  
Study site personnel will examine each subject’s mouth to ensure that the study treatment 
was ingested. 
When subjects self-administer study treatment(s) at home, compliance with CAB and  
RBT dosing will be assessed through verifying the diary entries and querying the subject 
during the site visits and documented in the source documents and case report form 
(CRF).  A record of the number of CAB and RBT capsules dispensed to and taken by
each subject must be maintained and reconciled with study treatment and compliance 
records.  Treatment start and stop dates will also be recorded in the CRF.

6.7.
Treatment of Study Treatment Overdose
For this study, any dose of CAB >30 mg and RBT >300 mg within a 12 hour time period 
will be considered an overdose.
In the event of an overdose of RBT, and depending on the degree of overdose and 
investigator evaluation, gastric lavage and diuretic treatment should be carried out.
Supportive care and symptomatic treatment should be administered [Summary of Product 
Characteristics for Mycobutin, January 2016].
GSK does not recommend specific treatment for an overdose of CAB.  
In the event of an overdose the investigator should:
1. contact the Medical Monitor immediately
2. closely monitor the subject for AEs/ SAEs and laboratory abnormalities until CAB 
and RBT can no longer be detected systemically (at least 14 days for CAB)
3. obtain a plasma sample for pharmacokinetic (PK) analysis within 60 hours 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 subject.
6.8.
Treatment after the End of the Study
Subjects will not receive any additional treatment from GSK after completion of the 
study because only healthy volunteers are eligible for study participation.
6.9.
Lifestyle and/or Dietary Restrictions
6.9.1.
Meals and Dietary Restrictions

Subjects must refrain from consumption of red wine, Seville oranges, grapefruit 
or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit 
juices from 7 days prior to the first dose of study medication until after the final 
PK sample.

Dosing of study medication on non-PK days may be with or without food, but 
dosing on serial PK days (Day 14 in Period 1 and Day 28 in Period 2) must be 
after an overnight fast of at least 6 hours, and no food will be allowed for 4 hours 
after dosing on these serial PK days.

Screening and Critical Baseline Assessments
Cardiovascular medical history/risk factors (as detailed in the CRF) will be assessed at 
screening.
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.  
7.3.
Safety
Planned time points for all safety assessments are listed in the Time and Events Table 
(Section 7.1).  Additional time points for safety tests (such as vital signs, physical exams 
and laboratory safety tests) may be added during the course of the study based on newly 
available data to ensure appropriate safety monitoring.
7.3.1.
Adverse Events (AE) and Serious Adverse Events (SAEs)
The definitions of an AE or SAE can be found in Appendix 4.
The investigator and their designees are responsible for detecting, documenting and 
reporting events that meet the definition of an AE or SAE. 
For this study, the Sponsor considers seizures as an AE of special interest (see 
Investigator’s Brochure for further information). Where seizures or suspected 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 
AE/SAE page (see Appendix 4, Section 12.4).
7.3.1.1.
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 subject consents to participate in the 
study up to and including any follow-up contact. 

AEs will be collected from the start of Study Treatment until the follow-up 
contact. Refer to Section 7.3.1.3.

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 CRF.

All SAEs will be recorded and reported to GSK within 24 hours, as indicated in 
Appendix 4.

2016N269788_02
CONFIDENTIAL
205712
39

Investigators are not obligated to actively seek AEs or SAEs in former study 
subjects. However, if the investigator learns of any SAE, including a death, at any 
time after a subject 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.
NOTE: 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 
Appendix 4.
7.3.1.2.
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 subject 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?” 

“Have you taken any new medicines, other than those provided in this study, since 
your last visit/contact?” 
7.3.1.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
subject at subsequent visits/contacts.  All SAEs will be followed until resolution, until the 
condition stabilizes, until the event is otherwise explained, or until the subject is lost to 
follow-up (as defined in Section 5.4). Further information on follow-up procedures is 
given in Appendix 4.
7.3.1.4.
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 subjects and the safety of a product under 
clinical investigation are met. 
GSK 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.
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.

7.3.2.
Pregnancy

Details of all pregnancies in female subjects will be collected after the start of dosing 
and until the last follow-up assessment.

If a pregnancy is reported then the investigator should inform GSK within 2 weeks 
of learning of the pregnancy and should follow the procedures outlined in Appendix 
5.
7.3.3.
Physical Exams

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. 

A brief physical examination will include, at a minimum assessments of the skin,
lungs, cardiovascular system, and abdomen (liver and spleen).
An ocular assessment will be performed only for subjects who experience eye symptoms.

Investigators should pay special attention to clinical signs related to previous serious 
illnesses.
7.3.4.
Vital Signs

Vital signs will be measured in semi-supine position after 10 minutes rest and will 
include systolic and diastolic blood pressure and pulse rate. Temperature will also be 
obtained as part of the Vital Signs assessment. 

Measurements that deviate substantially from previous readings will be repeated 
immediately.

Two (2) blood pressure (BP) and heart rate (HR) measurement will be taken at pre-
dose on Day 1, at least 1 minute apart.  The mean value recorded at pre-dose will be 
classified as baseline.  Single BP and HR will be obtained at all other time points 
during the study. A single Temperature (TT) assessment will be obtained at Pre-dose 
as well as other time points during the study as specified in the Time and Event 
Table Section 7.1. 
7.3.5.
Electrocardiogram (ECG)

Two (2) 12-lead ECGs measurements will be performed with the subject in a semi-
supine position having rested in this position for at least 10 minutes beforehand.

Measurements that deviate substantially from previous readings will be repeated 
immediately.
Two (2) measurements will be taken at pre-dose on Day 1, at least 5 minutes 
apart.  The mean value recorded at pre-dose will be classified as baseline.  Single 
ECG measurements will be performed at all other time points.  12-lead ECGs will be 
obtained during the study using an ECG machine that automatically calculates the 
heart rate and measures mean PR interval, QRS, QT, and QTcF (QT corrected by 
Fridericia’s formula) intervals.

Clinical Safety Laboratory Assessments
All protocol required laboratory assessments, as defined in Section 7 must be conducted 
in accordance with the Laboratory Manual, and Protocol Time and Events Schedule.
Laboratory requisition forms must be completed and samples must be clearly labeled 
with the subject number, protocol number, site/centre number, and visit date. Details for 
the preparation and shipment of samples will be provided by the laboratory and are 
detailed in the laboratory manual.  Reference ranges for all safety parameters will be 
provided to the site by the laboratory responsible for the assessments.
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 CRF.
Refer to the laboratory manual for appropriate processing and handling of samples to 
avoid duplicate and/or additional blood draws.
Haematology, clinical chemistry, urinalysis and additional parameters to be tested are

Pharmacokinetics
7.4.1.
Blood Sample Collection
Blood samples for pharmacokinetic (PK) analysis of CAB, will be collected at the time 
points indicated in Section 7.1, Time and Events Table.  The actual date and time of each 
blood sample collection will be recorded.  The timing of PK sample collection may be 
altered and/or PK samples may be obtained at additional time points to ensure thorough 
PK monitoring.  
Collect whole blood (2 mL) sample into a properly labeled K3EDTA evacuated blood 
collection tube.  Record the exact date and time of sampling in the CRF, as appropriate. 
Immediately after collection, gently invert (DO NOT SHAKE) the evacuated blood 
collection tube 8-10 times to mix the K3EDTA anticoagulant with the whole blood and 
place the sample(s) on ice. 
Within 1 hour of sample collection, separate the plasma by refrigerated (4 C) 
centrifugation at 1,500 to 2,000 x g for a minimum of 10 minutes.
Immediately after sample processing freeze the plasma storage tubes in the upright 
position in a non-self-defrosting freezer. Store at -20C or lower until transfer to 
bioanalytical facility.
Shipping procedures are provided in the Study Reference Manual (SRM).

Sample Analysis
Plasma analysis will be performed under the control of PTS-BIB/TPR, GlaxoSmithKline. 
The details of the analysis 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 parent compounds, any remaining plasma may be 
analyzed for other compound-related metabolites and the results reported under a 
separate Platform Technologies and Science (PTS), GlaxoSmithKline protocol.
7.5.
Genetics
Information regarding pharmacogenetic (PGx) research is included in Appendix 4.  The
IRB/IEC and, where required, the applicable regulatory agency must approve the PGx 
assessments before these can be conducted at the site.  In some cases, approval of the 
PGx assessments can occur after approval is obtained for the rest of the study.  If so, then 
the written approval will clearly indicate approval of the PGx assessments is being 
deferred and in most cases, the study, except for PGx assessments, can be initiated.  
When PGx assessments will not be approved, then the approval for the rest of the study 
will clearly indicate this and therefore, PGx assessments will not be conducted.

STATISTICAL CONSIDERATIONS AND DATA 
ANALYSES
9.1.
Hypotheses
This study is designed to estimate the drug-interaction effect of RBT on CAB PK 
parameters.  No formal hypothesis will be tested.  An estimation approach will be used to 
evaluate the effect of RBT on CAB PK.  Point estimates and corresponding 90%

confidence intervals (CIs) will be constructed for the comparisons of interest 
(test:reference).
9.1.1.
Primary Comparisons of Interests
The primary comparisons will be made for the repeated dose PK parameters of CAB 
when given alone in Period 1 (reference treatment) and when co-administered with 
steady-state RBT in Period 2 (test treatment).

90% CIs will be provided for the treatment comparisons (test:reference).
9.2.
Sample Size Considerations
9.2.1.
Sample Size Assumptions
The sample size of 15 to obtain 12 evaluable subjects was chosen based on an expected 
withdrawal rate of approximately 20% and the within-subject variability of CAB, to 
address the objectives of the study.
The within-subject variations in PK parameters from previous tablet administration in 
CAB studies [GlaxoSmithKline Document Number RM2008/00856/00, ITZ111839 and 
GlaxoSmithKline Document Number 2011N122099_01, LAI116181] were in the range 
of 6.7-7.8%, and 6.9-11.4%, for the CAB PK parameters AUC(0-τ)/AUC(0-∞) and Cmax 
respectively. 
Based on a within-subject coefficient of variation (CVw) of 11.4% and a sample size of 
12 evaluable subjects, it is estimated that the half width of the 90% confidence interval 
for the treatment difference on log-scale will be within 8.3% of the point estimate for 
AUC(0-τ) and Cmax.  If the point estimate of the ratio of geometric means is 1, then 90% 
confidence interval will be approximately (0.92, 1.09)
9.2.2.
Sample Size Sensitivity
Using sensitivity analysis assuming higher within-subject CVw of 22.8%  and a sample 
size of 12 evaluable subjects, it is estimated that the lower and upper bounds of the 90% 
CI for  the treatment difference on log-scale would be within 16.7% of the point estimate 
for AUC(0-t) and Cmax.
9.2.3.
Sample Size Re-estimation or Adjustment
No sample size re-estimation or adjustment will be performed.

Data Analysis Considerations
9.3.1.
Analysis Populations
Safety Population
All subjects who enroll into the study and receive at least one dose of study drug will be 
included in the Safety Population.  This will be the population for the safety analyses, and 
for summarization of baseline/demographic characteristics.
Pharmacokinetic Concentration Populations
The CAB PK Concentration Population will include all subjects who undergo plasma PK 
sampling and have at least one evaluable PK assay results.  CAB assay results from 
samples collected from a subject with emesis occurring within 4 hours of the dose will 
not be considered as evaluable.  These populations will be used for the concentration 
listing.
Pharmacokinetic Parameter Populations
The CAB PK Parameter Population for this study will include all subjects with CAB PK 
parameters estimated.  These populations will be used for PK parameter listing. PK 
parameter populations will also be used for plotting of the individual concentration-time 
data.
Pharmacokinetic Summary Population
The CAB PK Summary Population for this study will include subjects who have CAB 
PK parameter estimates from both serial PK sampling time periods 1 and 2.  These 
populations will be used for the concentration and PK parameters summary figures and 
tables and for the statistical analysis of PK parameter data.
9.3.2.
Interim Analysis
No interim analysis will be performed.
9.4.
Key Elements of Analysis Plan
Final analysis will be performed after the completion of the study and final datasets 
authorization.
Data will be listed and summarized according to GlaxoSmithKline reporting standards, 
where applicable. Listings will be sorted by subject, period, day, and time, noting 
treatment; summaries will be presented by treatment, day, and time.
Unless stated otherwise, descriptive summaries for continuous variables will include n, 
mean, standard deviation (SD), coefficient of variation for the mean (%CV), median, 
minimum, and maximum, geometric mean with associated 95% confidence interval (CI), 
and the between-subject CV (%CVb) for the geometric mean; whereas, n and percent will 
be used as summary statistics for categorical variables.

Baseline or pre-dose assessment is the last available assessment prior to time of the first 
dose unless it is specified otherwise. If there are multiple assessments collected on the 
same scheduled time, the average of these assessments will be used. For tabulated safety 
summaries, only the scheduled assessments will be included in the summary tables.
Version 9.3 or higher of the Statistical Analysis Software (SAS) system will be used to 
analyze the data as well as to generate tables, figures, and listings.
Complete details will be documented in the Reporting and Analysis Plan (RAP).
9.4.1.
Primary Analyses
Pharmacokinetic data will be presented in graphical and/or tabular form and will be 
summarized descriptively. All pharmacokinetic data will be stored in the Archives, 
GlaxoSmithKline Pharmaceuticals, R&D.
Pharmacokinetic Analyses
Pharmacokinetic analyses will be the responsibility of Clinical Pharmacokinetics 
Modeling & Simulation Department, Quantitative Sciences, within GlaxoSmithKline.  
Plasma CAB concentration-time data will be analyzed by non-compartmental methods 
with WinNonlin Professional 5.2 or higher.  Calculations will be based on the actual 
sampling times recorded during the study.  From the plasma concentration-time data, the 
following pharmacokinetic parameters will be determined, as data permit: maximum 
observed plasma concentration (Cmax), time to Cmax (tmax), area under the plasma 
concentration-time curve at the end of the dosing interval (AUC(0-)) and C(plasma 
concentration at the end of the dosing interval).
Statistical Analysis of Pharmacokinetic Data
All of the PK parameters will be log-transferred, except tmax.
Pre-dose concentrations collected between Days 13-14 and Day 26-28 will be used to 
assess for achievement of steady-state of CAB when CAB is given with RBT.  
Analysis of variance (ANOVA), considering treatment as fixed effect, will be performed 
using SAS Mixed Linear Models procedure to evaluate the effect of RBT on CAB PK 
parameters: AUC(0-) and Cmax, The ratios of geometric least square (GLS) means and 
associated 90% CIs will be estimated for the PK parameters AUC(0-) and Cmax.
9.4.2.
Secondary Analyses
Safety data will be presented in tabular and/or graphical format and summarized 
descriptively according to GSK’s Integrated Data Standards Library (IDSL) standards.
The point estimates of the geometric least squares (GLS) mean ratio for the PK 
parameters C, t1/2  and CL/F and the associated 90% CIs will be provided for treatment 
comparisons (test:reference).  The PK parameters will be log-transformed prior to 
analysis and treatment comparisons will be expressed as ratios on the original scale as

Appendix 3 - Genetic Research
Genetics – Background
Naturally occurring genetic variation may contribute to inter-individual variability in 
response to medicines, as well as an individual's risk of developing specific diseases. 
Genetic factors associated with disease characteristics may also be associated with 
response to therapy, and could help to explain some clinical study outcomes. For 
example, genetic variants associated with age-related macular degeneration (AMD) are 
reported to account for much of the risk for the condition [Gorin, 2012] with certain 
variants reported to influence treatment response [Chen, 2012]. Thus, knowledge of the 
genetic etiology of disease may better inform understanding of disease and the 
development of medicines. Additionally, genetic variability may impact the 
pharmacokinetics (absorption, distribution, metabolism, and elimination), or 
pharmacodynamics (relationship between concentration and pharmacologic effects or the 
time course of pharmacologic effects) of a specific medicine and/or clinical outcomes 
(efficacy and/or safety) observed in a clinical study.
Genetic Research Objectives and Analyses
The objectives of the genetic research are to investigate the relationship between genetic 
variants and: 

Response to medicine, including any treatment regimens under investigation in this 
study or any concomitant medicines;

HIV 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 Reporting and Analysis Plan 
(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 subject who is enrolled in the study can participate in genetic research.  Any subject 
who has received an allogeneic bone marrow transplant must be excluded from the 
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 subject 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 
the subject 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 subject 
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.
Subjects can request their sample to be destroyed at any time.
Informed Consent
Subjects 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.
Subject Withdrawal from Study
If a subject who has consented to participate in genetic research withdraws from the 
clinical study for any reason other than being lost to follow-up, the subject 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 

2016N269788_02
CONFIDENTIAL
205712
61
If a subject withdraws consent for genetic research or requests sample destruction for any 
reason, the investigator must complete the appropriate documentation to request sample 
destruction within the timeframe specified by GSK and maintain the documentation in 
the site study records. 
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 subject 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. 
Screen and Baseline Failures
If a sample for genetic research has been collected and it is determined that the subject 
does not meet the entry criteria for participation in the study, then the investigator should 
instruct the subject 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 Subject’s Genetic Data
GSK may summarize the genetic research results in the clinical study report, or 
separately and may publish the results in scientific journals. 
GSK may share genetic research data with other scientists to further scientific 
understanding in alignment with the informed consent. GSK does not inform the subject, 
family members, insurers, or employers of individual genotyping results that are not 
known to be relevant to the subject’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.

Appendix 4: Definition of and Procedures for Recording, 
Evaluating, Follow-Up and Reporting of Adverse Events
12.4.1.
Definition of Adverse Events
Adverse Event Definition:

An AE is any untoward medical occurrence in a patient or clinical investigation 
subject, 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 judgment 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).
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 subject’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 subject’s 
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 

2016N269788_02
CONFIDENTIAL
205712
63
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.
12.4.2.
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:
a.
Results in death
b.
Is life-threatening
NOTE:
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
subject 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.
c.
Requires hospitalization or prolongation of existing hospitalization
NOTE:

In general, hospitalization signifies that the subject 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.
d.
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 

2016N269788_02
CONFIDENTIAL
205712
64
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.
e.
Is a congenital anomaly/birth defect
f.
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 subject 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
g.
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 
subjects receiving anticoagulants.  If INR measurement is obtained, the value is to be 
recorded on the SAE form.
12.4.3.
AEs of Special Interest:
Seizure
Three cases of seizures have occurred in the CAB program cumulatively through
01 October 2016. 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 subjects and clinical confounders in each case.
When seizures or suspected 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 AE/SAE page.

2016N269788_02
CONFIDENTIAL
205712
65
12.4.4.
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 
CRF

It is not acceptable for the investigator to send photocopies of the subject’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 subject identifiers, with the exception of the 
subject number, will be blinded on the copies of the medical records prior to 
submission of 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.
12.4.5.
Evaluating AEs and SAEs
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and will assign it to one of the following categories:

Mild:  An event that is easily tolerated by the subject, 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.
IMPORTANT – PLEASE NOTE THE FOLLOWING STATEMENT:
For this study the above criteria regarding mild, moderate and severe will be used in
combination with the Modified Division of AIDS Table for Grading Severity of Adult
Adverse Experiences, December 2004 (Appendix 6). In the InForm electronic data
capture system intensity of adverse events will be recorded using the following 
categories:
1 = Mild or Grade 1

2016N269788_02
CONFIDENTIAL
205712
66
2 = Moderate or Grade 2
3 = Severe or Grade 3
4 = Grade 4

X = Not applicable
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 
the occurrence of each AE/SAE.

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 the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE 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 and SAEs

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 or SAE.

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 subject dies during participation in the study or during a recognized follow-up 

2016N269788_02
CONFIDENTIAL
205712
67
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.
12.4.6.
Reporting of SAEs to GSK
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

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 at this beginning of the protocol on the 
Sponsor/Medical Monitor Contact Information page.

Appendix 5: Modified List of Highly Effective Methods for 
Avoiding Pregnancy in FRP and Collection of Pregnancy 
Information
12.5.1.
Modified List of Highly Effective Methods for Avoiding Pregnancy 
in Females of Reproductive Potential (FRP)
The list does not apply to FRP with same sex partners or for subjects who are and will 
continue to be abstinent from penile-vaginal intercourse on a long term and persistent 
basis, when this is in line with their preferred and usual lifestyle (true abstinence). 
Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods), 
declaration of abstinence for the duration of exposure to IMP and withdrawal are not 
acceptable methods of contraception.
1. Intrauterine device (IUD) or intrauterine system (IUS) that meets the <1% failure rate 
as stated in the product label and does not contain a medication.
2. Male partner sterilization with documentation of azoospermia prior to the female 
subject's entry into the study, and this male is the sole partner for that subject 
[Hatcher, 2011]. The documentation on male sterility can come from the site 
personnel’s: review of subject’s medical records, medical examination and/or semen 
analysis, or medical history interview provided by her or her partner.
These allowed methods of contraception are only effective when used consistently, 
correctly and in accordance with the product label. The investigator is responsible for 
ensuring that subjects understand how to properly use these methods of contraception.
12.5.2.
Collection of Pregnancy Information

Investigator will collect pregnancy information on any female subject, who becomes 
pregnant while participating in this study.

Information will be recorded on the appropriate form and submitted to GSK within 2 
weeks of learning of a subject's pregnancy.

Subject 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 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 Appendix 5. 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.
Any female subject who becomes pregnant while participating 

Will be withdrawn from the study.

Investigator will attempt to collect pregnancy information on any female partner of a 
male study subject who becomes pregnant while participating in this study.  This 
applies only to subjects who are randomized to receive study medication. 

After obtaining the necessary signed informed consent from the female partner 
directly, the investigator will record pregnancy information on the appropriate form 
and submit it to GSK within 2 weeks of learning of the partner’s pregnancy.

Partner will also be followed to determine the outcome of the pregnancy.  Information 
on the status of the mother and child will be forwarded to GSK. 

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated 
delivery date.  Any termination of the pregnancy will be reported regardless of fetal 
status (presence or absence of anomalies) or indication for procedure.

TOTAL BILIRUBIN ELEVATION
Grade 1 (mild) bilirubin elevation (1.1 - 1.5 times ULN) or Grade 2 (moderate 
- 1.6-2.5 times ULN):
Any bilirubin value above the upper limit of normal must be repeated and fractionated 
(direct and indirect bilirubin).  Subjects may continue study medication.  Subjects should 
be followed up until resolution (return to baseline) of elevation.
Grade 3 (severe – 2.6-5.0 times ULN) or 4 (life-threatening - > 5.0 times ULN) 
bilirubin elevation:
Any bilirubin value above the upper limit of normal must be repeated and fractionated 
(direct and indirect bilirubin).  Subjects will permanently discontinue study medication 
and be withdrawn from the trial.  Subjects should be followed up until resolution (return 
to baseline) of bilirubin elevation.
AST AND ALT ELEVATION
See Appendix 2.
RASH
Grade 1 rash (Localized macular rash):
Subjects with Grade 1 rash should be evaluated by the Investigator immediately.  A 
dermatologist may be consulted and a biopsy may be obtained if recommended by the 
dermatologist.  The study drug should be permanently discontinued if the following signs 
or symptoms are noted at any time:
13. Temperature > 38.5°C
14. Lymphadenopathy
15. Pharyngitis
16. Any indication of internal organ involvement (hepatitis, nephritis)
In the absence of the above signs or symptoms, subjects with Grade 1 rash may continue 
the study drug at the discretion of the Investigator.  The subject should be advised to 
contact the Investigator immediately if there is any worsening of the rash, if any systemic 
signs or symptoms worsen, or if mucosal ulceration develops. If the rash is considered to 
be most likely due to concomitant illness or non-study medication, standard management, 
including discontinuation of the likely causative agent, should be undertaken. If no other 
causative factor is found after clinical evaluation, the subject may be treated 
symptomatically until the rash resolves. Antihistamines, topical corticosteroids or

antipruritic agents may be prescribed.  The subject should remain on the study to be 
followed for safety and PK as outlined in Section 7.3 and Section 7.4
Grade 2 rash (Diffuse macular, maculopapular, or morbilliform rash OR Target 
lesions):
Subjects with Grade 2 rash should be evaluated by the Investigator immediately.  Digital 
photographs should be obtained.  A dermatologist may be consulted and a biopsy may be 
obtained if recommended by the dermatologist.  The study drug should be permanently 
discontinued if the following signs or symptoms are noted at any time:
17. Temperature > 38.5°C
18. Lymphadenopathy
19. Pharyngitis
20. Any indication of internal organ involvement (hepatitis, nephritis)
In the absence of the above signs or symptoms, subjects with Grade 2 rash may continue 
the study drug at the discretion of the Investigator.  It should be noted that oral mucosal 
erosions may be part of a Grade 2 rash.  Any mucosal ulceration increases the severity 
of the rash to at least Grade 3.  The subject should be advised to contact the Investigator 
immediately if there is any worsening of the rash, if any systemic signs or symptoms 
worsen, or if mucosal ulceration develops. If the rash is considered to be most likely due 
to concomitant illness or non-study medication, standard management, including 
discontinuation of the likely causative agent, should be undertaken. If no other causative 
factor is found after clinical evaluation, the subject may be treated symptomatically until 
the rash resolves. Antihistamines, topical corticosteroids or antipruritic agents may be 
prescribed.  The subject should remain on the study to be followed for safety and PK as 
outlined in Section 7.3 and Section 7.4.
Grade 3 rash (Diffuse macular, maculopapular, or morbilliform rash with vesicles 
or limited number of bullae OR Superficial ulcerations of mucous membrane 
limited to one site):
Subjects with a Grade 3 rash will permanently discontinue the study medication.  The 
subject should be evaluated in the physician’s office immediately and should be seen in 
the physician’s office or contacted by phone every 2 days until the rash resolves.  A 
dermatologist should be consulted and digital photographs and a biopsy should be 
obtained.  Antihistamines, topical corticosteroids or antipruritic agents may be prescribed 
at the discretion of the Investigator.  The subject 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.  The subject should remain on the 
study to be followed for safety and PK as outlined in Section 7.3 and Section 7.4.
Grade 4 rash (Extensive or generalized bullous lesions OR Stevens-Johnson 
syndrome OR Ulceration of mucous membrane involving two or more distinct 
mucosal sites OR Toxic epidermal necrolysis (TEN)):

reaction and/or if any systemic signs or symptoms worsen.  If the allergic reaction is 
considered to be most likely due to concomitant illness or non-study medication, standard 
management, including discontinuation of the likely causative agent, should be 
undertaken.  If no other causative factor is found after clinical evaluation, the subject may 
be treated symptomatically until the rash resolves. Antihistamines, topical corticosteroids 
or antipruritic agents may be prescribed.  The subject should remain on the study to be 
followed for safety and PK as outlined in Section 7.3 and Section 7.4. 
Grade 3 allergic reaction (Generalized urticaria or angioedema):
Subjects will permanently discontinue the study medication and be withdrawn from the 
trial.  Subjects will be treated as clinically appropriate.  Subjects should be followed up 
until resolution of the adverse event and standard management should be undertaken.
Grade 4 allergic reaction (Anaphylaxis):
Subjects will permanently discontinue the study medication and be withdrawn from the 
trial.  Subjects will be treated as clinically appropriate.  Subjects should be followed up 
until resolution of the adverse event and standard management should be undertaken.

Protocol Changes for Amendment 01
Summary of Changes and Rationale for Amendment No. 1
Section 
Section Title 
Change
Rationale
12.5.1. 
Modified List of Highly 
Effective Methods for 
Avoiding Pregnancy in 
Females of 
Reproductive Potential 
(FRP)
Clarification to abstinence was 
added.
This clarification 
was made to 
clarify that true 
abstinence
established prior 
to the start of this 
study is an 
acceptable method 
of contraception 
when this is in line 
with the subjects 
preferred and 
usual lifestyle.
12.5.1. 
Modified List of Highly 
Effective Methods for 
Avoiding Pregnancy in 
Females of 
Reproductive Potential 
(FRP)
The double barrier method: 
condom and occlusive cap 
(diaphragm or cervical/vault caps) 
plus spermicidal agent 
(foam/gel/film/cream/suppository) 
was removed from the list of 
highly effective methods for 
avoiding pregnancy in FRP.
This method of 
contraception is 
not considered a  
highly effective 
method for 
avoiding 
pregnancy
in females of 
reproductive 
potential (FRP) for 
this protocol.
Modified text incorporated into protocol amendment 01:
12.5.1. Modified List of Highly Effective Methods for Avoiding Pregnancy
in Females of Reproductive Potential (FRP)
The list does not apply to FRP with same sex partners or for subjects who are and will 
continue to be abstinent from penile-vaginal intercourse on a long term and persistent 
basis, when this is in line with their preferred and usual lifestyle (true abstinence).
Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods), 
declaration of abstinence for the duration of exposure to IMP and withdrawal are not 
acceptable methods of contraception.

1. Intrauterine device (IUD) or intrauterine system (IUS) that meets the <1% failure
rate as stated in the product label and does not contain a medication
2. Male partner sterilization with documentation of azoospermia prior to the female
subject's entry into the study, and this male is the sole partner for that subject
[Hatcher, 2011]. The documentation on male sterility can come from the site
personnel’s: review of subject’s medical records, medical examination and/or semen
analysis, or medical history interview provided by her or her partner.
These allowed methods of contraception are only effective when used consistently, 
correctly and in accordance with the product label. The investigator is responsible for
ensuring that subjects understand how to properly use these methods of contraception.
