 INTRODUCTION 
1.1 Background and Rationale 
The burden of HIV infection worldwide is disproportionately borne by youth. 
Despite reductions in other age groups, the number of deaths attributable to HIV is rising in the 
adolescent age group, with AIDS being the leading cause of death among adolescents in Africa and the 
second leading cause for adolescents worldwide.1 Between 2005 and 2012, the number of AIDS-related 
deaths decreased by 30% for all ages except adolescents, who experienced a 50% increase in that same 
period. Youth are over-represented in the current HIV epidemic: in 2017, nearly 2000 of the 5000 new 
HIV infections which occur globally each day are in individuals aged 24 years or younger (one-third of 
these new HIV infections occur in youth aged 15 to 24).2 Among youth, there are also key populations 
that bear disproportionate burdens of HIV and are the most vulnerable. These key populations (YKPs) 
include young men who have sex with men (YMSM) globally and adolescent/young adult women in 
Sub-Saharan Africa.3  
Girls and young women between 15 and 30 years old have an extraordinarily high incidence, 
particularly in countries such as South Africa.4-6 The most recent household survey confirms the 
feminization of the epidemic nationally in that country, with adolescent girls 15 to 19 years of age four 
times more likely to be infected than their male counterparts.6 In recent HIV prevention trials, annual 
HIV incidence was 5-6% in South African young women, even in the context of counseling, condom 
provision and STI treatment.7-9 HIV prevention and decreasing HIV-related deaths depend critically on 
reaching adolescents, engaging them in HIV prevention research, and ensuring access to HIV prevention 
products via regulatory approvals. 
Oral Pre-exposure Prophylaxis is highly efficacious against HIV, but poor adherence has limited its 
effectiveness for youth.  
Tenofovir-based ARV regimens have been shown to significantly reduce HIV acquisition among men 
who have sex with men (MSM), heterosexual men and women, injection drug users and HIV sero-
discordant couples.10-13 Given the growing body of evidence about its effectiveness, including 
encouraging “real world” demonstration projects14,15, oral daily PrEP is now recommended for HIV 
prevention by the US Centers for Disease Control and Prevention (CDC), the World Health 
Organization (WHO) and a growing number of countries worldwide16,17. 
As with many daily medication regimens, the effectiveness of oral PrEP is highly dependent on 
adherence to the prescribed drugs. This appears to be particularly true for adolescents and young adults. 
In at least two clinical trials of women, oral PrEP did not show a decreased risk of HIV transmission and 
these results appeared to be related to poor adherence among study participants.7,18 In the FEM-PrEP 
study, for example, only 12% of women had serum drug levels associated with good adherence 
throughout trial participation.18 Similarly, the VOICE trial7 failed to show efficacy of either oral PrEP or 
daily vaginal gel, largely attributable to very low rates of adherence among a cohort of young women. 
Trials of other short-acting prevention technologies have also been negatively impacted by low 
adherence among the youngest participants. The FACTS 001 licensure trial18 for tenofovir gel that 
followed CAPRISA 004 recently reported no effect on HIV acquisition among a large sample of young 

 
HPTN 084-01, FINAL Version 1.0 
 
17 of 117 
14 October 2019 
South African women, primarily because participants struggled to adhere to the prescribed regimen.9 
Furthermore, results from two recent randomized trials of the dapivirine vaginal ring, which showed 
modest efficacy overall, demonstrated consistently low adherence among women under the age of 21, 
which attenuated the overall protective effect of the intervention.8,19 
For youth, PrEP may only reach its full potential with drugs that do not depend on daily or near-daily 
pill-taking. 
Challenges with adherence to medication are commonplace among adolescents, regardless of whether it 
is adherence to a treatment or prevention regimen. Non-adherence among youth is often a reflection of 
both the biological and behavioral transitions that occur during this developmental time, including 
increased autonomy from parents/caregivers, increased importance of peers and corresponding 
vulnerability to peer influence and stigma, and undeveloped cognitive capacity for organization and 
planning. Rates of adherence among adolescents and young adults with chronic illnesses requiring daily 
medication, such as HIV, diabetes, and cancer are consistently low, with estimates often about 50% 
overall.20,21 Similarly, rates of adherence to oral prevention strategies, such as contraception, 
demonstrate similar challenges to daily adherence. Many studies have found that continuation rates are 
lower and pregnancy rates are higher among adolescents using oral contraception versus long-acting 
contraceptives.22,23 Just as increased choice in type and method of delivery of contraceptive methods has 
increased acceptability and effectiveness for contraception24,25, we believe that expanded choices for 
HIV prevention will similarly increase utilization, satisfaction, and effectiveness. 
A recent discrete choice experiment conducted in Kenya and South Africa26, which was designed to 
assess preferences for prevention technologies among young women ages 18 to 30 years, found that an 
injection every 2 to 3 months was preferred over daily oral pills, and that there was desire for multi-
purpose prevention technologies combining contraception with prevention of HIV. The development of 
alternative agents for PrEP, with more adherence-friendly schedules, could increase prevention choices 
and increase acceptability. Long-acting injectable agents have the potential to prevent HIV acquisition 
without relying on adherence to a daily oral regimen27.  
Adult safety data on long-acting cabotegravir (CAB LA) will need to be expanded to adolescents in 
order to license the product for adolescents under the age of 18 
Currently, two parent protocols (HPTN 083 and HPTN 084) are being conducted globally. HPTN 083 is 
a study being done to evaluate the efficacy of CAB LA for PrEP in HIV-uninfected MSM and TGW, 
ages 18 and older, and is enrolling approximately 4500 MSM and TGW in the Americas, Asia and 
South Africa. HPTN 084 is a study being done to evaluate the safety and efficacy of CAB LA, compared 
to daily oral TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®), for PrEP in 
approximately 3,200 HIV-uninfected women ages 18 to 45 years old in sub-Saharan Africa who are at 
risk for acquiring HIV. 
Historically, medical treatments applied to children were often based upon testing done only in adults, 
rendering evidence-based treatments less available to children due to their exclusion from studies. Since 
1996, one goal of the National Institutes of Health as well as the US FDA has been to increase the 
participation of children in research so that adequate data can be developed to support treatment (and 
prevention) modalities for disorders and conditions that affect adults as well as children. In order for 
adolescents to access safe and effective new biomedical HIV prevention products at the same time that 
these products are approved and marketed for adults, the scientific development and testing of these 
products for adolescents must proceed concurrently.28 Similarly, adolescents are often excluded from 

 
HPTN 084-01, FINAL Version 1.0 
 
18 of 117 
14 October 2019 
prevention intervention trials due to concerns from regulatory or ethics boards as well as investigator 
concerns around the complexity of recruitment/retention and/or fear that adolescent difficulties will 
adversely impact the primary outcomes of the trial.29,30 This exclusion from large Phase 3 trials as well 
as hesitancy to launch youth-focused bridging trials only exacerbates the gaps in HIV prevention 
intervention availability and access, which continues to fuel the HIV epidemic among vulnerable young 
people.  
This trial has been designed as an open label clinical trial. An unblended, single arm trial is most 
developmentally-appropriate for youth, while also minimizing participant and staff burden. The design 
of the parent trials (HPTN 083 and HPTN 084) is quite complicated. They are double-blind, double 
dummy trials with a complex visit schedule and a lengthy commitment for participant completion. The 
team feels it is unreasonable to request this type of commitment and burden from vulnerable youth (and 
their parents/caregivers), when efficacy data can be extrapolated from the parent studies. Furthermore, 
open label prevention studies have demonstrated that product adherence improves when participants 
know what they are taking and can be counseled about the unblinded product.31,32,33 
1.2 Overview of Oral CAB and CAB LA  
The majority of information contained in this section of the protocol is a summary of information 
provided in the CAB Investigator’s Brochure (IB) V8.0, Effective Dated 17 December 2018, unless 
otherwise noted. 
CAB is an investigational HIV integrase strand transfer inhibitor (INSTI) that has attributes favorable 
for both HIV treatment and prevention indications. Currently in Phase 2 and Phase 3 clinical trials, it 
was initially selected for development based on its potential for a high genetic barrier to resistance and a 
PK profile that allows low-dose, once-daily oral dosing or monthly to bimonthly parenteral dosing using 
a nanosuspension formulation. An oral tablet version of CAB has also been developed as lead-in therapy 
to establish acute safety and tolerability in individual participants prior to switching to the long-acting 
formulation. CAB LA has an absorption half-life of 21 to 50 days in adults.  
 Non-human Primate Studies Relevant to Rectal Exposures 
CAB LA has demonstrated activity in preventing simian human immunodeficiency virus (SHIV) 
infection in non-human primate models.34 In a preclinical study evaluating the potential of CAB LA for 
PrEP, 2 weekly doses of CAB LA (50 mg/kg intramuscularly [IM]) were highly protective against 
weekly rectal challenges with SHIV162p3 (50% tissue culture infective dose [TCID]50) for up to eight 
exposures. In these protected animals, the plasma concentrations of CAB LA throughout the period of 
virus challenges were comparable to clinically-relevant concentrations in humans. In follow-up studies, 
a single dose of CAB 50 mg/kg IM one week prior to the serial weekly viral challenges with 
SHIV162p3 (50 TCID50) were evaluated. The percent of challenges resulting in infection was calculated 
relative to the plasma CAB protein-adjusted 90% inhibitory concentration (PA-IC90) value. None of 59 
challenges resulted in infection when plasma levels were greater than 3 times the PA-IC90, compared 
with 1 out of 22 challenges resulting in infection when plasma levels were between one to three times 
the PA-IC90, and 11 out of 43 challenges resulting in infection when plasma levels were less than 1 times 
the PA-IC90. Twelve out of 26 challenges resulted in infection in control animals; rectal tissue levels of 
CAB were approximately 20% of plasma levels.35   
 Non-human Primate Studies Relevant to Vaginal Exposure 

 
HPTN 084-01, FINAL Version 1.0 
 
19 of 117 
14 October 2019 
CAB prevented SHIV infection in two non- human primate models. In one study which used 
medroxyprogesterone acetate (Depo-Provera) to increase the risk of infection,35 CAB LA 50 mg/kg 
offered 90% protection from high-dose exposure to SHIV162P3. In a second study using the same SHIV 
with a low-dose challenge model, animals were provided complete protection by CAB.34,35  To evaluate 
concentrations at the site of virus entry, CAB concentrations were measured in vaginal and rectal 
secretions. CAB was consistently detected in both vaginal and rectal secretions throughout the 4 weeks 
of the study.  At first dose, peak CAB concentrations in vaginal secretions (median, 911 ng/mL; range, 
427 to 1,877) were similar to those seen in rectal secretions (median, 2,215 ng/mL; range, 647 to 2,680) 
(P = 0.240), albeit at concentrations significantly lower than in plasma (P = 0.002) (Figure 1. 
CAB 
LA PK Profiles following Q8W Dosing in Males and Females (HPTN077, Cohort 2)) The area under 
the curve values over 28 days (AUC0–28d) in vaginal secretions were compared to the values with those 
seen in plasma or rectal secretions. The AUC0–28d values in vaginal secretions (median, 11,511 ng × 
day/mL; range, 3,956 to 14,011) were lower than those in rectal secretions (median, 26,717 ng × 
day/mL; range, 10,120 to 39,989), although the difference was not statistically significant. In contrast, 
AUC0–28d values in vaginal secretions were lower than those in plasma (median, 70,333 ng × day/mL; 
range, 40,265 to 169,341) (P = 0.002) (Figure 1).  Despite the lower CAB concentrations in vaginal 
secretions, concentrations remained above the PA-IC90 throughout the entire 4-week period after each 
dose (Figure 1).  In summary, CAB partitioning in vaginal, cervical, and rectal tissues is within the 
range seen in humans. It should be noted that similar doses of CAB appeared to result in higher 
concentrations of drug in male animals than females.34,35  In addition, the concentration of SHIV in 
rectal tissues was greater than in cervical tissue.34,35  In summary, these preclinical non-human primate 
studies suggest that CAB can be expected to protect women from HIV.  However, because of 
differences in men and women and human and macaques, careful consideration of the most appropriate 
dose and frequency of dosing is essential (see below).  
1.3 Metabolism 
CAB is highly protein bound in human plasma (>99%). It is a substrate for permeability glycoprotein 
(Pgp), but because of its high permeability, no alteration in absorption would be expected by co-
administration of either Pgp or breast cancer resistance protein (BCRP) inhibitors. Elimination occurs 
predominantly in feces via biliary excretion. Renal excretion is minimal, with less than 1% of the dose 
eliminated in the urine. The primary route of biotransformation is conjugation with glucuronic acid (M1) 
via uridine diphosphate glucuronyltransferase type 1A1 (UGT 1A1).  
1.4 Preclinical Studies 
The CAB toxicology package supports the careful conduct of clinical studies with CAB up to the no 
observed adverse effect level (NOAEL) exposure in the 39-week monkey toxicity study (Week 39 
gender mean AUC0-24 and Cmax of 547 g·h/mL and 34.6 g x h/mL, respectively). The results of the 
multiple dose rat subcutaneous (SC) and IM toxicity study, along with data from the oral toxicity 
program, support the careful conduct of clinical studies with CAB LA up to the mean Cmax plasma 
concentration observed at the NOAEL in the 39-week monkey oral CAB toxicity study (34.6 g/mL) or 
the mean AUC1,440-2,160h following once monthly IM dosing at the NOAEL (75 mg/kg/dose) in the 
3-month rat CAB LA toxicity study (92,566 g x   h/mL). 
In a rat pre- and post-natal study, CAB exposure during pregnancy resulted in increased offspring 
mortality at the highest dose tested (1000mg/kg/day). This is in excess of the established safety limit 
(NOAEL) of 5mg/kg/day. The NOAEL is >20 fold the predicted clinical Cmax and AUC exposures in 
humans for both HIV treatment and prevention. The mechanism for the reduction in viable pups at this 

 
HPTN 084-01, FINAL Version 1.0 
 
20 of 117 
14 October 2019 
supratherapeutic dose up to 4 days post-partum is unknown. Clinical dosing in HPTN 077 (a safety, 
tolerability, and PK of CAB LA in HIV-uninfected, low-risk men and women) is approximately 7-fold 
below the NOAEL in 10-day-old rat offspring. Importantly, an early fetal development (EFD) study in 
rats was negative. 
1.5 Dose Rationale 
 Oral CAB  
CAB is readily absorbed following oral administration in healthy and HIV-infected participants with a 
median Tmax of approximately two hours. The apparent terminal phase half-life following oral 
administration is approximately 40 hours.   
In a short-term monotherapy study, seven HIV-infected participants received oral CAB 5 mg once daily 
for 10 days, which achieved a geometric mean Day 10 plasma trough concentration (C) of 0.57 g/mL, 
3.4-fold above the PA-IC90 value, and was associated with a mean Day 11 HIV ribonucleic acid (RNA) 
change from a baseline of -2.2 log10 c/mL.36,37 In LATTE, the Phase 2b study in HIV-infected, ART-
naïve adult participants,38 suppression of HIV replication was accomplished with oral CAB at doses of 
10 mg to 60 mg once daily in combination with two nucleoside reverse transcriptase inhibitors (NRTIs), 
and HIV viral load was maintained below 50c/mL at similar rates across oral CAB 10 mg to 60 mg 
doses through >72 weeks when combined with oral rilpivirine (RPV) 25 mg once daily. The geometric 
mean individual average plasma C following oral CAB 10 mg and 30 mg once daily were 1.35 g/mL, 
eight-fold above PA-IC90, and 4.2 g/mL, 25-fold above PA-IC90, respectively.   
An oral tablet version of CAB has been developed as lead-in therapy to establish acute safety and 
tolerability in individual participants prior to switching to the long-acting formulation. Oral CAB has 
been studied at doses between 5 mg and 150 mg in HIV-uninfected and HIV-infected adults. The oral 
formulation of CAB has been generally well-tolerated as single or repeated doses in clinical studies of 
HIV-uninfected adults. CAB 30 mg once daily has been used as the oral lead-in in the ECLAIR (Phase 
IIa Safety and PK Study of Cabotegravir LA in HIV-uninfected Men), LATTE-2 (CAB + RPV as Long-
Acting Maintenance Therapy), HPTN 077 (A Phase IIa Safety, Tolerability and Acceptability Study of 
an Investigational Injectable HIV Integrase Inhibitor for PrEP in HIV Uninfected Men and Women) 
studies, and 4 Phase III studies in adults  - 2 PrEP studies, HPTN 083 and HPTN 084, and 2 treatment 
studies (201584 (FLAIR) and 201585 (ATLAS)). Therefore, CAB 30mg once daily has been selected 
for the oral run-in regimen for this study. 
 CAB LA  
Through October 2018, approximately 4236 adult participants have been exposed to at least one dose of 
CAB (oral and/or LA) across 18 completed or ongoing Phase 1, 2 & 3 clinical trials (see Table 1).  
The regimen proposed for this study was evaluated in HPTN 077 Cohort 2.  For the HPTN 077 study, 
participants were low-risk HIV-uninfected individuals at eight sites globally, randomized (3:1) to daily 
oral CAB 30mg (or placebo) for four weeks (W), followed by CAB (or PBO) 800mg IM at W5, 17, and 
29 (Cohort 1) or 600 mg IM at W5, 9, 17, 25, and 33 (Cohort 2]). One hundred ten participants enrolled 
in Cohort 1, 89 in Cohort 2. Ninety-four percent of participants completed the oral phase, 89% received 
at least one injection, and 75% completed all injections, which did not differ by arm, cohort or sex. Over 
41 weeks, injection site pain and injection site reactions (ISR) were more common in CAB vs. placebo. 
No other differences were found in safety or tolerability. ISR led to injection discontinuation in 2/134

(1.5%).  Cohort 2 dosing consistently achieved plasma trough targets whereas Cohort 1 dosing did not. 
Overall, CAB was well tolerated among low-risk HIV-uninfected men and women. Pharmacokinetics 
supported the development of CAB for HIV prevention using 600 mg IM every 8 weeks with a 4-week 
loading dose for all sexes. 
In HPTN 077, overall 65% of the study participants were female. Median BMI was 28 kg/m2 in female 
participants and 25 kg/m2 in male participants. Among participants in Cohort 1 (who received a split 
injection of CAB-LA 800mg IM q12 weeks), males had a higher geometric mean Cmax after the first 
injection, but significantly lower trough concentrations than female participants after all three injections. 
Trough CAB concentrations were below 4X PA-IC90 in 72%, 35%, and 32% of male participants at 
weeks 17, 29, and 41, respectively. In contrast, trough CAB concentrations in female participants were 
largely at goal throughout the trial, with 24%, 5% and 0% of female participants having trough 
concentrations below 4X PA-IC90 at weeks 17, 29, and 41. In Cohort 2 (CAB LA 600mg IM q 8 
weeks), male participants achieved significantly higher CAB Cmax, AUC0-tau, and Ctrough after the first 
injection than female participants (and overall, participants with lower BMI were observed to have 
significantly higher trough concentrations after the first injection). However, CAB trough concentrations 
< 4X PA-IC90 (between 1 and 4X the PA-IC90) were observed in 5%, 20%, 20%, 16%, and 11% of 
male participants after injections 1, 2, 3, 4, and 5, respectively.  For female participants, 21%, 5%, 3%, 
0%, and 3% had CAB trough concentrations below 4X PA-IC90 after injections 1, 2, 3, 4, and 5, 
respectively.

During the 76-week follow-up phase of the HPTN 077 study39, differences were observed in the median 
time to undetectable cabotegravir levels between men and women: 42.7 weeks (range 20.4-134) in men 
as compared to 66.3 weeks (range 17.7-182) in women. CAB was detected in plasma in 22% of men and 
63% of women at 60 weeks and 13% of men and 44% of women at 76 weeks post the last injection).

The observed pharmacokinetics in HPTN 077 supported the development of CAB for HIV prevention 
using 600mg IM every 8 weeks with a 4-week loading dose for all sexes.40 Although the medium 
waning PK tail for women participating in HTPN 077 was 66.3 weeks, the HPTN 084-01 team has 
determined that participants in this trial should receive TENOFOVIR/EMTRICITABINE (TRADE 
NAME: TDF/FTC, TRUVADA®) for 48 weeks, in order to mimic the parent trial, HPTN 084. 
1.6 Genital Tract (GT) Tissue Levels after Oral and Injectable Administration 
Genital tissue concentrations have been measured after CAB LA 400 mg IM single dose administration 
in 24 healthy men and 15 healthy women. Median cervical and vaginal tissue concentrations ranged 
from 16-28% (overall range 0-70%) of plasma concentrations, roughly 1 x PA-IC90 (0.166 µg/mL).  
Median rectal tissue concentrations were ≤ 8% of plasma concentrations (range 0-20%).41 Further tissue 
studies using single and multiple doses of the 800 mg IM dose are currently ongoing.   
1.7 Pediatric Dosing 
Currently, there is no previous clinical trial experience with oral CAB or CAB LA in humans under 18 
years of age. However, the IMPAACT 2017 began enrolling in April 2019. IMPAACT 2017 is a Phase 
I/II, multi‐center, open‐label, non‐comparative study to confirm the dose and evaluate the safety, 
tolerability, acceptability, and PK of oral CAB, long-acting injectable CAB (CAB LA), and long-acting 
injectable RPV (RPV LA) administered monthly among up to 155 virologically suppressed HIV‐1 
infected children and adolescents aged 12 to <18. 
In HPTN 077, 89 healthy females received an oral lead-in (OLI) of CAB 30 mg once daily x 4 weeks 
prior to initiating CAB LA injections.  These participants had a median weight of 71 kg, and 6 weighed  
 50 kg.  Therefore, administration of the OLI to participants  50 kg is expected to achieve exposures 
within the range of prior experience, and PK will not be evaluated following oral administration in this 
study.  Following a 1-week washout, 40 of 89 female participants in HPTN 077 received the proposed 
CAB LA Q8W regimen (Figure 1).    
A population PK model (n=1647) that included data from HPTN 077 (n=134, 89 females, 45 males) and 
15 other studies was used to predict exposures following the proposed CAB LA Q8W regimen in 
adolescents.  Gender and BMI are significant covariates affecting the absorption rate following IM 
administration and were retained in the model to extrapolate to smaller adolescent females expected to 
enroll in HPTN 084-01.  Model predicted concentrations in adolescent females (simulated with median 
weight and BMI of 59 kg and 22 kg/m2, respectively) to enroll in HPTN 084-01 are similar to adult 
females in HPTN 077 and below oral dosing, and therefore are expected to be safe in this population 
(Table 1).  Greater than >95% are expected to achieve trough concentrations > 4x PA-IC90 following 
the 5th injection.  This regimen is currently being evaluated in uninfected adult males and females in 
HTPN 083 and HPTN 084, respectively, and has maintained HIV suppression in infected adults when 
combined with RPV LA (LATTE-2).

Plasma CAB concentrations are expected to be detectable in a majority of subjects for one year 
following the final injection.   
Based on adult dosing data and pharmacokinetic modeling, oral CAB 30mg and CAB LA 600mg IM are 
expected to be safe in adolescents and have been selected as the initial regimen for IMPAACT 2017 
study - the same as the adult CAB regimen in current Phase III studies. While somewhat higher CAB 
plasma concentrations are expected in lower weight adolescent participants, the safety and tolerability 
seen in adults at the higher oral CAB dose of 60 mg daily and CAB LA dose of 800mg q 8 weeks 
tempers any safety concerns.  
This protocol will enroll using a weight-based approach rather than age based. This allows for an 
eventual adolescent indication for LA CAB in adolescents at-risk, regardless of age. The supplemental 
adolescent indication for Truvada® was entirely weight-based (down to 35 kg) for adolescents at risk of 
HIV. Also, by not specifying a lower limit of age, this allows sites the flexibility to enroll participants 
that meet the behavioral and physical criteria necessary to qualify. Each site will have ethics review and 
will consider these criteria in light of community standards; and each investigator of record will be able 
to determine whether a candidate is appropriate for enrollment or not. These decisions will then be made 
with consideration for the local context of each site/community, rather than arbitrarily choosing what 
age should be the lower limit. Additionally, we need to acquire more data for use of this product in 
adolescents under 50 kg.  
Dose adjustments are not anticipated for this protocol. However, a pre-specified weight-based analysis 
from Cohort 1 of IMPAACT 2017 is scheduled to compare dosing safety above and below 50kg (110 
lbs.). The HPTN 084-01 protocol team will review these findings when data is available to determine 
whether the dose of the oral and injectable CAB study products must be revised. In that case, the new 
doses will be specified in a letter of amendment.

1.8 Pregnancy and Pregnancy Prevention with CAB Use 
There is no requirement to exclude women of reproductive potential from clinical trials of CAB based 
on reproductive toxicity findings available to date. Given the limitations of the data and because animal 
studies are not always predictive of the human situation, women of reproductive potential are required to 
adopt highly reliable means of contraception during participation and throughout long term follow up 
phases of studies following exposure to CAB LA.  
In vitro and clinical data suggest that CAB is unlikely to cause or be subject to clinically significant drug 
interactions with the components of hormonal contraceptives.  In a clinical drug-drug interaction study 
in healthy female volunteers, oral CAB had no significant impact on the pharmacokinetics of either 
levonorgestrel (LNG) or ethinyl estradiol (EE) containing combination oral contraceptive.42 There were 
no apparent differences in pharmacodynamic assessments of follicular stimulating hormone (FSH), 
luteinizing hormone (LH) or progesterone and concomitant administration of CAB and LNG/EE was 
well-tolerated in the study.  Because the pathways of metabolism and excretion are comparable between 
the oral and injectable formulation of CAB, it is expected that the results of this drug interaction study 
can be extrapolated to long-acting CAB.  In clinical studies, combination estrogen and progestin or 
progestin-only hormonal contraceptives available in oral, injectable or implant formulations may be 
used concurrently with CAB.  However, clinical data are limited evaluating the use of injectable or 

 
HPTN 084-01, FINAL Version 1.0 
 
25 of 117 
14 October 2019 
implantable forms of hormonal contraceptives and CAB to date. Progestin-only products, such as 
injectable NET-EN and DMPA, and etonogestrel implants are commonly prescribed, specifically in 
SSA. Although the metabolic pathways for such products are complex and vary somewhat from ethinyl 
estradiol and levonorgestrel, no pharmacokinetic drug-drug interaction between CAB and progestin-only 
contraceptives is anticipated.43 HPTN 077 did not find any evidence that use of hormonal contraceptives 
altered the CAB LA concentration profile during or after injections in either univariate or multivariate 
analysis.43 
 Dolutegravir and Pregnancy 
Dolutegravir (DTG) is an integrase inhibitor in the same class of pharmaceuticals as CAB.  Thus far, 
limited safety or efficacy data for DTG in pregnancy in humans have been published or presented. In 
May 2018, WHO and several other regulatory agencies released advisories regarding the safety of 
dolutegravir in early pregnancy.44 
This was based on information received from the Botswana NICHD-funded Tsepamo Birth Outcomes 
Surveillance Study, the largest body of data related to birth outcomes following the use of DTG in 
pregnancy. This study was designed to evaluate adverse birth outcomes by maternal HIV status and 
ART regimen, and to determine whether there is an increased risk of neural tube defects (NTDs) among 
infants exposed to efavirenz (EFV) from conception. Botswana’s HIV program moved to universal ART 
with DTG/TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) as first line 
treatment for patients starting ART (including pregnant women) in May of 2016 (women already on 
other regimens were not switched to DTG). The previous first-line regimen was 
EFV/TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®). Almost all women 
on DTG-based and EFV-based ART took these drugs in combination with 
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®). More than 95% of 
women in Botswana deliver in a hospital, and obstetric records were available for >99% of women. The 
Tsepamo surveillance study is conducted at 8 of the largest public maternity wards across Botswana 
(representing ~45% of the total births in the country). Research assistants abstract ART data from the 
maternity card for all consecutive in-hospital deliveries (both HIV-infected and HIV-uninfected 
women). Each newborn, whether stillborn or live-born, undergoes a systematic infant surface 
examination that is completed by trained nurse midwives. Reports and photographs (where available) of 
major abnormalities are reviewed by an experienced medical geneticist who is blinded to exposure 
information. During a preliminary unscheduled analysis of the Tsepamo data collected between August 
15, 2014 and May 1, 2018, which was undertaken at the request of colleagues who were preparing for a 
WHO meeting, the investigators found 4 cases of neural tube defects in babies of 426 women who 
became pregnant while taking DTG (prevalence 0.9%). This rate compares to a 0.1% risk of neural tube 
defects in infants born to women taking other antiretroviral medicines at the time of conception. Data is 
expected on the pregnancy outcomes of an additional 600 women in the Tsepamo study who were taking 
DTG around the time of conception. A follow-up analysis of 1729 pregnant women in the same 
observational cohort in Botswana found that there was no difference in the risk for any adverse birth 
outcome among children born to women on dolutegravir as compared to those on efavirenz (33.2% vs 
35% for DTG and EFV, respectively; aRR 0.95, 95% CI 0.88-1.03). There was also no difference in the 
occurrence of any severe birth outcome (10.7% for women on DTG versus 11.3% for women on EFV; 
aRR 0.94, 95% CI 0.81-1.11).45 More data are also expected to be forthcoming from other studies of 
DTG in pregnancy. These data will provide more information on the safety of DTG for women of 
childbearing age.

Cabotegravir is not dolutegravir. While these medications share a common molecular backbone, and 
have a similar mechanism of activity, they are separate chemical compounds and have differences in 
antiviral activity, pharmacokinetics, metabolism and drug-drug interactions. It is not known if the safety 
signal identified with dolutegravir will be observed with cabotegravir, in keeping with a class effect. 
Cabotegravir was evaluated in a complete package of reproductive toxicology studies, including 
embryo-fetal development studies, and no safety findings suggestive of teratogenesis or neural tube 
defects were identified in the December 2017 version of the Investigator’s Brochure.  Nevertheless, 
given limited experience with use of cabotegravir in pregnancy, women of reproductive potential are 
required to adopt highly reliable means of contraception during participation and throughout long-term 
follow-up phases of studies using CAB LA.  
1.9 Hepatic and Central Nervous System Adverse Events 
As part of the early phase development of CAB (HPTN 077, LATTE and LATTE-2), some participants 
developed transaminase elevations, which were clinically asymptomatic and resolved rapidly with 
cessation of study product.   
In a single-dose study (LAI116815), a healthy male volunteer with a history of prior seizure activity 
(one episode 14 years prior), on no anti-epileptic medication, experienced an unwitnessed seizure event 
270 days after a single injection of CAB LA 400 mg IM.  Plasma levels of CAB were undetectable for 4 
months prior to the seizure event. The event occurred in the context of consumption of approximately 10 
cans of beer, and a magnetic resonance imaging (MRI) study was unrevealing for pathology. An 
electroencephalogram was consistent with benign juvenile epilepsy; the participant recovered without 
additional events.  
A participant in the ongoing Phase 2b LATTE-2 trial of HIV-infected individuals received oral 
ABC/3TC with CAB 30 mg daily for 20 weeks, and received ABC/3TC, CAB and oral RPV for 4 
weeks, all without incident or clinically significant AEs or laboratory abnormalities. He was randomized 
to continue CAB LA 400 mg IM + RPV LA 600 mg IM Q4W. On day 349 of overall CAB treatment 
(139 days of oral CAB + 210 days of CAB LA exposure), the participant was found in his apartment by 
emergency personnel unresponsive, unconscious, and having generalized tonic-clonic seizures. The 
participant was hospitalized in the intensive care unit, had recurrent seizures, and was found to have 
anoxic brain injury resulting in death. The participant had no prior history of seizures, and clinical 
history and toxicity screens suggested possible recreational substance use.   
A participant in the healthy volunteer HPTN 077 study, with a prior history of seizures treated with 
Dilantin had been taken off Dilantin 2 years prior to study participation and had been seizure-free. A 
“spell” 1 month prior to study enrollment did not prompt re-initiation of anti-epileptics. Oral CAB 30 
mg (or placebo) was administered for four weeks without incident, and Day 62 after administration of 
CAB LA 800 mg IM x 1 (or placebo), the participant had an unwitnessed seizure event; he was 
subsequently hospitalized for transient dizziness and hemiparesis, for which work-up was unrevealing, 
and resolved with meclizine treatment. The participant recovered without additional events and is not 
planned for additional intraperitoneal (IP) dosing.  
A participant in HPTN 077 without known pre-existing liver disease, and without HIV-infection 
developed Grade 3 ALT elevation after 12 weeks of injectable placebo treatment; the participant was 
asymptomatic, and ALT returned to normal 15 weeks after withdrawal of study product.  A serologic 
and ultrasonographic evaluation did not reveal alternative etiology for the ALT elevation; no biopsy was 
performed.

Weight gain 
There is emerging evidence from randomized trials that the use of integrate inhibitors could lead to 
significant increases in body weight.46 Two trials of raltegravir and three involving dolutegravir all 
observed greater weight gain increases in integrase containing regimens. These effects appear to vary by 
gender and race, with highest increases observed in women and those of black race. The mechanism for 
this needs to be fully elucidated. These data are from populations receiving treatment and more data is 
needed in healthy HIV uninfected populations using PrEP. HPTN 077 evaluated changes in weight and 
fasting metabolic parameters in 177 HIV-uninfected individuals randomized to cabotegravir or a placebo 
who had received at least one injection. No differences between study groups were found for change in 
weight or fasting metabolic parameters overall, or for subgroups. Among the 146 participants with 
paired weights, between W0 and W41 the median increase in weight for CAB treated participants was 
1.1 (IQR -0.9, +3.0) kg compared to median 1.0 (IQR -1.2, +3.2) kg gained by PBO treated participants 
( =+0.1 kg, p=0.66). The distribution of weight changes across the 41 week treatment period did not 
differ between CAB and PBO-treated participants, nor when divided into the oral phase ( =+0.3 kg, 
p=0.6) and the injection phase ( =+0.2 kg, p=0.65). A 5% or greater increase in weight from W0 to W41 
was seen in 24 (22%) CAB participants and 7 (18%) of PBO participants (p=0.62).47  
1.11 
Rationale for use of Oral Run-in Prior to Injectable Dosing 
The CAB LA formulation has a PK decay rate that exposes the injected individual to detectable levels of 
CAB for a year or more after an injection (see Section 1.5.2 of the protocol). In order to maximally 
identify any acute toxicity prior to administration of a non-dialyzable, non-removable depot injection, a 
five-week lead-in period of daily oral (short acting) CAB will be employed. This lead-in period will be 
evaluated with serial safety assessments prior to injectable administration. The current plans for product 
labeling, should FDA approval be granted, include an oral lead-in strategy when adequate safety is 
established after four weeks of oral drug exposure. The 5-week exposure in this study is designed to 
provide un-interrupted study product coverage while awaiting return of the Week 4 safety laboratory 
assessments.   
 
 STUDY OBJECTIVES AND DESIGN 
2.1 Primary Objectives  
• To evaluate the safety, tolerability and acceptability of CAB LA in healthy, HIV-
uninfected female adolescents aged below 18 years. 
 
2.2 Secondary Objectives 
• To examine adherence to and timeliness of injections over time among adolescent 
participants provided CAB LA and information regarding its safety and unknown 
efficacy.  
• To examine patterns of sexual risk behavior over time among adolescent participants 
provided CAB LA and information regarding its safety and unknown efficacy. 
• To evaluate the safety of CAB LA for 48 weeks of follow-up after final injection.

2.3 To evaluate the pharmacokinetics of CAB LA. Study Design and Overview 
We propose a single arm, open label, safety, tolerability, and acceptability study (n=50) in sexually-
active, healthy adolescents assigned female sex at birth. We have chosen to enroll an adolescent 
population that is sexually-active, yet not at the highest risk for HIV exposure due to several reasons. 
First, this is the first protocol to study a new prevention product (CAB LA) among adolescent minors – 
and the primary outcome of interest is safety. Safety studies within a new population with an unproven 
product typically enroll “healthy” volunteers. The adult safety study for CAB LA was HPTN 077, which 
enrolled lower risk adults in a manner similar to the approach adopted for these sub-studies. Second, 
adolescents are considered a vulnerable population and the efficacy of CAB LA has yet to be proven. 
Thus, a young person at very high risk would potentially benefit more from oral 
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®), which is highly 
efficacious and approved for use by adolescents to prevent HIV infection. Finally, adolescent sexual 
activity is highly variable and we will likely see individual variation in sexual risk over the course of the 
study visits. Should promising efficacy data from adult populations become available during the 
implementation of this study, the protocol team will consult with the DSMB to consider broadening the 
sexual risk criteria to enroll high-risk adolescents. 
Study participation includes, Step 1: a 5-week oral CAB 30mg QD safety lead-in followed by a series of 
5 intramuscular (IM) injections of 3 mL (600 mg) administered at 8-week intervals after a 4-week 
loading dose (injections at weeks 5, 9, 17, 25 & 33) in Step 2. Adherence support strategies (e.g., 
counseling, reminders, pill cases) will be included to support pill-taking during the first five weeks and 
to support retention during the injectable phase. A safety visit will follow each injection to ascertain 
pharmacokinetic-peak safety data, including injection site reactions. Step 3: A blood draw visit, the +8 
Week Visit, will follow the last injection to monitor CAB drug levels. All participants who have 
received at least one injection will be followed for 48 weeks after their last injection. Waning levels of 
cabotegravir (the PK tail) will be covered with locally sourced oral TENOFOVIR/EMTRICITABINE 
(TRADE NAME: TDF/FTC, TRUVADA®) for daily use for 48 weeks. Behavioral and acceptability 
data will be collected via computer-assisted self-interview (CASI).  
Participants who discontinue study product during Step 2 for any reason other than HIV infection or AE 
occurrence will be transitioned to open label TDF-FTC for 48 weeks. 
Finally, in-depth qualitative interviews will be conducted at the end of the product exposure period 
(Week 34) with 10 participants (total, across sites) to explore issues of acceptability and preference for 
oral tablets and/or injections. Additionally, up to 10 parents/guardians of participants will be asked to 
participate in in-depth interviews to explore facilitators and barriers to adolescent enrollment in 
biomedical clinical trials as well as parental acceptability of injectable prevention products for 
adolescents.   
As previously mentioned, we have chosen an unblinded, single arm trial because it is most 
developmentally-appropriate for adolescents and minimizes participant and staff burden, while also 
offering a more streamlined visit schedule than the parent protocols and, hopefully, promoting study 
drug adherence.

 Study Duration 
The initial phase, Step 1, will be an oral lead-in phase of 5 weeks. After that, follow up on study product 
will be for 34 weeks followed by quarterly visits for 48 weeks after the final injection. Total participant 
commitment for the entire study is approximately 87 weeks, or approximately 1.5 years. We anticipate 
recruitment for the study will take approximately 12 months. 
 
 STUDY POPULATION 
We are using clinical sites that have proven ability to enroll and retain adolescent participants, astute 
awareness of the developmental and cultural issues experienced by adolescents, as well as outstanding 
productivity with previous bio-behavioral clinical trials. Participants will be recruited from the clinical 
sites’ patient populations, through community-based venues by working with sites’ community partners 
and Community Advisory Boards, as well as through social media and/or other technology-based 
recruitment methods successfully used in our previous PrEP studies for adolescents. 
Approximately 50 participants will be included in this study. Each site will be asked to work with its 
Community Advisory Board and outreach, education and recruitment teams to develop a recruitment 
plan appropriate for the local population. Participants will be selected for the study according to the 
criteria in Sections 3.1 and 3.2. Study participants will be recruited as described in Section 3.3. 
Requirements related to participant retention and withdrawal from the study are described in Sections 
3.5 and 3.6, respectively. Individual sites will be given enrollment targets such that overall cross-site 
enrollment meets overall protocol goals.

 Plans to move out of the geographic area within the next 18 months or otherwise unable to 
participate in study visits, according to the site investigator; 
 Pregnant or currently breastfeeding at the time of screening or intends to become pregnant 
and/or breastfeed while on study. 
3.3 Recruitment Process 
The study will be targeted towards at-risk, sexually active adolescent populations of female adolescents 
in SSA. Enrollment will occur over approximately 12 months. 
Sites will be responsible for developing appropriate recruitment processes that are geared toward their 
respective local communities.  All advertising materials must undergo approval by each participating 
site’s Institutional Review Board (IRB)/Ethics Committee (EC).  
Sites will implement wide-reaching educational efforts, community engagement, and multimedia 
advertising including rapidly changing and adaptive social media strategies to reach young populations. 
Participant retention during prolonged follow-up will be accomplished using study-visit incentives as 
permitted by local IRBs at the maximum permissible level. 
3.4 Co-Enrollment Guidelines 
Participants in this study will not be allowed to take part in other concurrent interventional research 
studies during their participation in the study. This is due in part to concerns about: 1) participant study 
burden, 2) limitations on per-unit-time phlebotomized blood volumes, and 3) to avoid confounding in 
the interpretation of the study data.  
3.5 Participant Retention 
Once a participant enrolls in this study, the study site will make every effort to retain the participant for 
the entire follow-up period. Study site staff are responsible for developing and implementing local 
standard operating procedures to target this goal. Components of such procedures may include: 
• Thorough explanation of the study visit schedule and procedural requirements during 
the informed consent process and re-emphasis at each study visit. 
• Thorough explanation of the importance of adherence/retention to the overall success 
of the study. 
• Collection of detailed locator information at the study Screening Visit, and active 
review and updating of this information at each subsequent visit, including where the 
participant lives and other locator venues.  
• Use of appropriate and timely visit-reminder mechanisms, including 
SMS/WhatsApp/text messaging. 
• Immediate and multifaceted follow-up on missed visits, including 
SMS/WhatsApp/text messaging. 
• Mobilization of trained staff to complete in-person contact with participants at their 
homes and/or other community locations. 

 
HPTN 084-01, FINAL Version 1.0 
 
33 of 117 
14 October 2019 
• Regular communication with the study community at large to increase awareness 
about HIV/AIDS and explain the purpose of HIV prevention research and the 
importance of completing research study visits. 
• Incentives or reimbursements as permitted by local IRB/ECs.  
3.6 Participant Withdrawal 
Regardless of the participant retention methods described in Section 3.5, participants may voluntarily 
withdraw from the study for any reason at any time.  
The IoR also may withdraw participants from study product dosing in order to protect their safety and/or 
if they are unwilling or unable to comply with required study procedures after consultation with the 
Protocol Chair, DAIDS Medical Officer, Statistical and Data Management Center (SDMC) Protocol 
Statistician, representatives from the Laboratory Center (LC), the Leadership and Operations Center 
(LOC) Clinical Research Manager (CRM), and others. 
Participants may be withdrawn from the study if the study sponsor, US government or regulatory 
authorities (including Office for Human Research Protections [OHRP] and the FDA), site IRBs/ECs and 
other regulatory bodies, or ViiV terminate the study prior to its planned end date. 
Every reasonable effort will be made to complete a final evaluation of participants who terminate study 
product prior to the final protocol-dictated study week, and study staff will record the reason(s) for all 
withdrawals from the study product in participants’ study records. In such cases, the IoR or designee 
must contact the CMC for guidance regarding final evaluation procedures.     
 
 STUDY PRODUCT CONSIDERATIONS 
Site pharmacists should consult the Pharmacy Guidelines and Instructions for DAIDS Clinical Trials 
Networks for standard pharmacy operations. Refer to study schema on page 15 for an overview of steps

HPTN 084-01, FINAL Version 1.0 
 
34 of 117 
14 October 2019 
All participants who have received at least one injection will be followed for 48 weeks after their last 
injection, beginning with a blood draw visit, the +8 Week Visit, that will follow eight weeks after the 
last injection to monitor CAB drug levels. Waning levels of cabotegravir (the PK tail) will be covered 
with locally sourced oral tenofovir/emtricitabine (TENOFOVIR/EMTRICITABINE (TRADE NAME: 
TDF/FTC, TRUVADA®)) for daily use for 48 weeks.  
 Oral Product 
Step 1 - Oral CAB tablets 30 mg are formulated as white to almost white oval-shaped film-coated tablets 
for oral administration. The tablets are packaged in high density polyethylene (HDPE) bottles with 
child-resistant closure that include an induction seal. The bottles contain 30 tablets and a desiccant. The 
bottles should be stored up to 30oC (86oF) and protected from moisture.    
Step 3 – TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) is a fixed dose 
combination tablet containing 200 mg of emtricitabine (FTC) and 300 mg of tenofovir disoproxil 
fumarate (TDF) in each tablet. The tablets must be stored as per the manufacturer’s recommendation. 
Refer to the package insert for recommended storage conditions. 
 Injectable Suspension 
The CAB study product (oral and LA injectable) being tested in this study is investigational and not yet 
approved by the US FDA for the treatment or prevention of HIV-1 infection. Further information on the 
study product is available in the IB, which will be provided by the DAIDS Regulatory Support Center 
(RSC). 
CAB LA formulation 
CAB LA is formulated as a sterile white to slightly pink colored suspension containing 200 mg/mL of 
CAB LA for administration by IM. The product is packaged in a 3 mL (600mg) vial. The total amount 
to be administered to each participant is 3 mL (600 mg) per intramuscular (IM) injection. The 
formulation does not require dilution prior to administration. CAB LA injectable suspension is to be 
stored up to 30oC (86oF), do not freeze.  
The investigational pharmacist(s) must be proficient in the preparation of study products using aseptic 
technique under a pharmacy biological safety cabinet (BSC) Class II or better isolator. Local regulations 
and site institutional policies and procedures for use of personal protective equipment, such as gloves, 
gowns, masks, and safety glasses, must be followed.  
One syringe containing 3 mL (600 mg) of CAB LA study product must be prepared using aseptic 
technique under a pharmacy BSC/isolator.  
Materials required for preparation and administration: 
1. One CAB LA 600 mg/3 mL vial 
2. Becton Dickinson (BD) 5-mL Syringe, Luer-Lok Tip, Product No.: 309646 or equivalent 
3. Needle for aspiration: BD general use sterile hypodermic needle, 21G x 1½ inch (e.g. 
    PrecisionGlide Needle, Product No.: 305165 or equivalent) 
4. Needle for intramuscular injection: BD IM sterile hypodermic needle, 23G x 1½ inch 
    (e.g. PrecisionGlide Needle, Product No.: 305194 or equivalent)

Preparation Steps: 
 
1 Remove one CAB LA 600 mg/3 mL vial from storage. If vials are stored in the refrigerator 
(2°C to 8°C), remove vial from the refrigerator and wait at least 15 minutes to equilibrate to 
room temperature. 
2. Vigorously shake the vial for a full 10 seconds, by shaking the vial with long arm movements. 
3. Invert the vial and inspect to ensure uniform suspension. If solid remains undispersed, repeat 
Steps 2-3 until all material is uniformly suspended. 
NOTE: It is normal to see small air bubbles at the end of shaking the vial for re-suspension. 
 
4. Using aseptic technique under a pharmacy BSC/isolator, flip off the plastic cap from the vial. 
Wipe the top of the vial with an alcohol pad and allow to dry. Do not touch the rubber stopper 
at any time. 
5. Remove a 5-mL syringe and a 21G x 1½ inch needle for aspiration. Attach the needle to the 
Luer connection of the syringe. 
6. With the needle sheath on, pull the syringe plunger rod to allow approximately 1 mL of air into 
the syringe. Remove the needle sheath. 
7. Push the needle through the vial stopper and inject approximately 1 mL of air into the vial.   
8. Withdraw the entire contents of the vial into the syringe. Since the suspension can contain 
some air after having shaken the vial, withdraw all suspension from the vial in order to be able 
to de-aerate the syringe properly. 
9. Record the time that the suspension was withdrawn from the vial into the syringe. 
10. Remove the needle that was used to withdraw the suspension into the syringe and discard the 
needle.  
11. Attach a 23G x 1½ inch needle for intramuscular injection to Luer connection of the syringe. 
Remove the needle sheath from the needle. 
12. De-aerate the syringe by first tapping a finger against the syringe and then by moving the 
plunger rod carefully forward with the needle in the upright position until the first drop of 
suspension appears. Remove the excess suspension in order to administer the correct volume (3 
mL). If needed, collect the excess suspension in a beaker in order to avoid spilling. 
 
After withdrawal of the suspension from the vial into a syringe, it is recommended to inject the 
suspension immediately. Do not exceed 2 hours between withdrawing the contents of the vial into a 
syringe (Step 8) and administration to the study participant.   
 
The prepared CAB LA suspension in a syringe must be stored at controlled room temperature between 
20°C to 25°C from the time it is withdrawn into a syringe to the time it is administered. 
 
Any entered vials or expired filled syringes should be disposed of in accordance with institutional or 
pharmacy policy. 
IM Dosing Considerations 

 
HPTN 084-01, FINAL Version 1.0 
 
36 of 117 
14 October 2019 
IM injections are administered into the gluteus muscle (gluteus medius method preferred) using a needle 
of appropriate gauge and length (recommended 1.5” 23-gauge needle for CAB LA).  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 (21 to 25 gauge) are permitted if needed to accommodate individual body 
type.  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.  
4.2 Study Product Acquisition and Accountability 
The CAB study products (oral and LA injectable) for Steps 1 and 2 are being provided by ViiV 
Healthcare. For Step 3, the sites will provide locally sourced TENOFOVIR/EMTRICITABINE 
(TRADE NAME: TDF/FTC, TRUVADA®) for 48 weeks after the participants’ last CAB LA injection. 
 Study Product Acquisition 
The CAB study products (oral and LA injectable) will be supplied through the National Institute of 
Allergy and Infectious Diseases (NIAID) Clinical Research Products Management Center (CRPMC). 
The study site pharmacist can obtain all the study products through the CRPMC by following the 
instructions in the Pharmacy Guidelines and Instructions for DAIDS Clinical Trial Networks, and 
instructions in the SSP Manual.    
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) will be obtained locally 
by the site. Contraceptive products will be provided by the sites.  
 Study Product Accountability 
The site pharmacist is required to maintain complete records of all study products received from the 
CRPMC and subsequently dispensed to study participants. All study products must be stored in the 
pharmacy. All unused study products must be destroyed after the study is completed, terminated or 
otherwise instructed by the study sponsor. The procedures to be followed are provided in the Pharmacy 
Guidelines and Instructions for DAIDS Clinical Trials Networks. 
4.3 Toxicity Management 
Toxicity management guidelines can be found in Appendix VI.    
4.4 Concomitant, Prohibited, and Precautionary Medications 
In order to avoid AEs caused by drug interactions, whenever a concomitant medication is taken, site 
staff must review the concomitant medication's and study product’s most recent package insert (PI - for 
Truvada®) and investigator’s brochure (IB - for cabotegravir) to obtain the most current information on 
drug interactions and contraindications.  Concomitant medications (prescription and non-prescription) 
should be administered only as medically necessary during the study.  
After Enrollment, for any precautionary or prohibited drug listed in the Truvada PI or cabotegravir IB, it 
is required that the HPTN 084 CMC be notified for recommendations for continuing or stopping (or 
holding) study product.

concentrations of emtricitabine and/or tenofovir. 
• NOTE:  Please report to the CMC if a participant takes a total daily dose of NSAIDS that meets 
or exceeds high dose for MORE than 72 consecutive hours. 
• NOTE:  Acyclovir and valacyclovir may be used when indicated. If needed for treatment – sites 
do NOT need CMC permission for the use of these products, but sites should counsel the 
participant to increase hydration to avoid additive nephrotoxicity; no additional laboratory 
monitoring is required per protocol.  
Further information regarding prohibited and precautionary concomitant medications, including 
rifampin, can be found in the SSP Manual and IB. The SSP Manual will be revised (as a whole or as a 
Memorandum of Changes) and re-issued when changes are made.   
All concomitant medications/preparations (prescription and non-prescription) including 
alternative/complementary medications/preparations (e.g., herbs, vitamins, etc.) taken within 30 days

 STUDY PROCEDURES 
Overviews of the study visit and procedures schedules are presented in Appendices I, II, III and 
Appendix IV (for suspected and/or confirmed HIV infection). Presented below is additional information 
for visit-specific study procedures. Detailed instructions to guide and standardize all study procedures 
across sites are included in the SSP Manual. 
5.1 Screening 
It is the responsibility of the local site to determine the best approach to screening.  Written informed 
consent and/or assent (as appropriate) will be obtained before any study procedures are initiated. Both 
clinical and laboratory evaluations will occur at this visit (see Appendix 1). Screening procedures may 
occur over one or more visits. The SSP Manual provides additional information regarding the 
procedures outlined below, including clinical and laboratory procedures and requirements. Enrollment 
must occur within 30 days of specimen collection at Screening for the clinical and laboratory evaluation 
and procedures (except for HIV RNA testing samples, which must be collected, and results obtained 
within 14 days before enrollment).  
Sites will follow the HIV testing algorithm for Screening included in the SSP Manual. If a 
reactive/positive/indeterminate result is obtained for any HIV test, the person is not eligible for the 
study.  Additional testing to confirm suspected HIV infection during Screening will be performed in 
accordance with local guidelines. If HIV infection is confirmed, participants will receive counseling and 
be referred for appropriate care, as necessary.   
Contraception counselling and provision must be initiated before or at the week 2 visit in Step 1 so that 
the method is in place prior to transition to Step 2.  
Individuals deemed not eligible will be informed that they do not meet the elibility criteria for the study 
and will be referred for appropriate medical care, if necessary.   
Potential participants may be rescreened once at the discretion of the IoR or their designee.  Further re-
screening may be permitted with prior approval of the CMC. However, potential participants with 
clinically-significant cardiovascular disease as outlined in the exclusion criteria in Section 3.2, or any 
reactive HIV test, may not be re-screened. Participants with symptoms concerning for acute HIV 
infection (per IoR or designee) may be re-screened in consultation with the CMC, once appropriate 
testing has ruled out acute HIV infection.      
5.2 Enrollment  
Baseline/Enrollment/Week 0 Visit 
Both clinical and laboratory evaluations will occur at this visit, along with behavioral and acceptability 
assessments (see Appendix 1 ).  
All HIV test results including testing for acute HIV from Screening, which must be performed within 14 
days of Enrollment, and at least one HIV test result from Enrollment must be available and confirmed to 
be negative/non-reactive PRIOR to provision of study product.  Results from the chemistry testing, liver 
function tests (LFTs), lipid profile, hematology testing, second instrumented HIV test, and urinalysis 
from this visit are NOT required prior to enrollment. 

 
HPTN 084-01, FINAL Version 1.0 
 
40 of 117 
14 October 2019 
Eligible participants will be reminded that the use of anticoagulant and/or antiplatelet medications as 
outlined in the SSP Manual are prohibited within seven days before and seven days after injections. 
Reminders will be built in to the concomitant medication history form. 
Participants will meet with study staff to receive education and information about the adherence during 
the oral phase, identify potential barriers to adherence for the participant, and decide on adherence 
support strategies that will facilitate adherence. During counseling, participants will be offered 
supportive tools such as discrete pill containers, mobile reminder tools including text messaging and/or 
mobile app alerts, and weekly telephone check-ins from study teams. 
All behavioral assessment measures will be programmed into CASI. Measures have been previously 
used either in adolescent biomedical prevention trials or in the Phase III adult trials of cabotegravir.  
A pregnancy test must be conducted on the same day that study product is dispensed, and the test must 
be confirmed to be negative prior to dispensing.   
At the end of this visit, participants will be dispensed oral cabotegravir, with first dose directly observed 
by study staff. Study product must be dispensed with instruction to participants. 
5.3  Step 1, Oral Run-in Phase: Safety Visits   
Oral Run-in Safety Visits at Weeks 2 and 4  
There will be 2 brief follow-up visits during the oral phase of cabotegravir for the purpose of safety and 
adherence checks. Both clinical and laboratory evaluations will occur at these visits (see Appendix 1). 
Adherence counseling will be provided at both Weeks 2 and 4 to address barriers to daily pill taking, as 
well as remind participants of adherence support options available to them. Pill counts will occur at 
these visits and participants will take a dose directly observed by study staff at each of these visits. 
Participants with pill counts resulting in less than 50% adherence at the Week 4 visit will not be allowed 
to transition to Step 2. Anyone not moving to Step 2 will be terminated from the study. 
Investigators should contact the CMC at 084-01cmc@hptn.org if a participant has missed or delayed 
week 4 visit or has not had sufficient oral drug exposure during the four-week oral run-in period to 
transition to step 2.  
 Management of Participants with AEs during Step 1 
The oral run-in (Step 1) is included to reduce risk to participants.  Participants with significant, negative 
side effects to oral study product will not continue on to Step 2, the Injection Phase.  See Table 5.1 for 
brief instruction and Appendix VI, Toxicity Management for detailed instruction on participant 
management.  All AEs are to be followed until the return to < Grade 2.

5.4 Transitioning from Step 1 to Step 2 
Conditions in Step 1 that could disqualify a participant from transitioning to Step 2 are as follows: 

 
HPTN 084-01, FINAL Version 1.0 
 
42 of 117 
14 October 2019 
• Pill count suggestive of less than 50% adherence at the Week 4 visit; 
• Missed or delayed Week 4 visit; 
• Not on effective long-term contraception at the Week 4 visit; 
• Any suspected or confirmed pregnancy (see SSP and Section 5.16); 
• Specific AEs per Table 5.1Error! Reference source not found.; 
• At substantial risk of HIV infection and/or qualifies for oral PrEP by local guidelines; 
• Any HIV reactive/positive test (see SSP and Section 5.12). 
 
If any of the above conditions occur, investigators should notify the HPTN 084-01 CMC at 084-
01cmc@hptn.org within one week of awareness for final determination of fitness to enter Step 2.  
 Early Discontinuation in Step 1 
Participants who do not enter Step 2 will discontinue study follow-up. Prior to termination, study staff 
will complete study evaluations due at the Week 4 visit in Appendix I, if possible. All appropriate 
referrals will be made to primary care service providers for sexual reproductive health and HIV 
prevention. Participants should continue contraception for at least 30 days following the last dose of oral 
CAB. 
5.5 Step 2, Injection Phase: Injection Visits  
Injection Phase Injection Visits at Weeks 5, 9, 17, 25, and 33  
All HIV test results from previous visits and at least one HIV test result from the current visit must be 
available and confirmed to be negative/non-reactive PRIOR to injection of study product. The injection 
may NOT be given if any HIV test is reactive/positive. For management of participants with an HIV-
positive test, see Section 5.10. 
Results from the other clinical and laboratory evaluations (e.g., chemistry, LFTs, hematology) from 
previous visits must be available and be reviewed by the IoR or their designee prior to provision of study 
product. Results from STI tests do not need to be reviewed prior to provision of study product. For 
management of participants with AEs, see Appendix VI, Toxicity Management. 
During Step 2, the injection phase of the study, all participants will have brief safety visits one week 
after each injection. Both clinical and laboratory evaluations will occur at both the injection visits and 
the safety visits as well as CASI administration for either behavioral or acceptability assessments (see 
Appendix II. Schedule of Evaluations for Injection– Step 2). 
5.6 Step 2, Injection Phase: Safety Visits  
Injection Phase Safety Visits at Week 6, 10, 18, 26, and 34 
During the injection phase of the study, all participants will have brief safety visits one week after each 
injection. Blood will also be collected at these visits to monitor drug levels of CAB. A three-month 
supply of TENOFOVIR/EMTRICITABINE [TRADE NAME: TDF/FTC, TRUVADA®]) will be 
provided at Week 34. 
5.7 Step 3, Follow-up Phase 
Follow-up Phase  

 
HPTN 084-01, FINAL Version 1.0 
 
43 of 117 
14 October 2019 
All participants will be followed quarterly for 48 weeks following their last injection.  
Step 3 will begin with the +8 Week Visit, in which participants who receive the Week 33 injection will 
return for a blood draw eight weeks afterwards, in order to monitor drug levels of CAB. Participants 
who do not receive the week 33 injection will have a +8 Week Visit after their last injection visit and 
continue to be followed per the Step 3 Follow-up Phase (see Appendix III).  
Both clinical and laboratory evaluations will occur during follow-up phase visits as well as CASI 
administration for either behavioral or acceptability assessments (see Appendix III. Schedule of 
Evaluations for Follow-up Phase – Step 3). Participants will also be monitored for increased HIV 
transmission risk behavior during this time and open-label oral PrEP provided at the clinical sites. 
5.8 Standard of Care (SOC) Counseling for all Participants 
 HIV and Risk Reduction Counseling 
HIV testing and risk reduction counseling will be provided at each study visit, in accordance with local 
SOC, and will include messaging about consistent condom use. Condoms will be offered to all 
participants at each study visit consistent with local standards.  
Increase in Risk for HIV Infection 
At any time during study participation, any participant whose risk for HIV increases such that they 
qualify for PrEP by local guidelines, and desire to start PrEP, will permanently discontinue study 
product and receive ongoing risk reduction counselling. Step 1 participants will be switched to open 
label TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) PrEP and not 
transition to Step 2. They will be referred for further HIV prevention services and exit the study. Step 2 
participants will switch to open label TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®)PrEP and remain in follow-up in Step 3. All cases should be communicated to the HPTN 
084-01 CMC at 084-01cmc@hptn.org.  
 
Post-exposure Prophylaxis (PEP) 
At any time during study participation, any participant who express concern about a potential HIV 
exposure will be referred for PEP services. Any participant receiving PEP will temporarily hold study 
product. Participants may qualify to resume study product dosing and remain in follow-up, after 
consultation with the HPTN 084-01 CMC at 084-01cmc@hptn.org. 
 Adherence Counseling and Monitoring 
The study will provide adherence support/counseling at baseline and at all follow-up visits for all 
participants and will be tailored to participants’ current study Step. During Step 1, participants will 
receive counseling focused on adherence to the oral CAB and messages about ensuring adequate dosing 
for safety prior to proceeding to Step 2. During Step 2, the importance of returning for injection visits on 
or as close to the scheduled date as practical will be emphasized. During Step 3, the focus will be on 
adherence to oral TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) PrEP. 
Throughout the study, participants will be reminded that efficacy of CAB LA for HIV prevention has 
yet to be established.

5.9 Injection Visit Windows 
The visit windows for all visits, including injection visits, are outlined in the SSP Manual. Refer to SSP 
for instruction on managing participants who report to clinic outside of injection window. 
The target visit windows for all visits, including injection visits, are outlined in the SSP Manual. In 
brief, the target visit window for injection visits for the Week 5 and 9 injections is +/- 3 days and is +/- 7 
days for all other injection visits. Visits conducted outside of the target visit windows are allowable 
without restriction and are also defined in the SSP Manual for scheduling guidance. Each study visit, 
including the injection visit, should ideally be conducted within the target date range. When that is not 
possible, visits outside of the target dates may be completed.  
5.10 
Procedures for Injectable Dosing 
Refer to Appendix VI, Toxicity Management, for general toxicity management, as well as specific 
clinical and laboratory toxicity management guidelines, including directions regarding temporary and 
permanent study product holds.        
5.11 
Participants with Suspected or Confirmed HIV Infection at Screening, Enrollment, or 
 
Follow-Up 
All participants with preliminary positive HIV test results at screening or throughout the study will be 
actively linked with care and treatment from their choice of primary HIV service provider. Each of the 
clinical study sites have adolescent-friendly HIV care clinics available.  
 Screening and Enrollment 
HIV testing will be performed to identify participants with HIV infection. Individuals who have one or 
more reactive / positive HIV tests at Screening or Enrollment are not eligible to participate in this study. 
Furthermore, at Screening and Enrollment individuals with any signs or symptoms consistent with acute 
(pre-seroconversion) HIV infection will not be enrolled, unless acute HIV infection is ruled out with 
appropriate laboratory testing, in consultation with the CMC. Signs and symptoms consistent with acute 
HIV infection are outlined in the SSP Manual.   
 After Study Enrollment 
Frequent testing for HIV acquisition during the study period (at all study visits in Step 1 and 3, and at all 
injection visits in Step 2) specified in the schedules of evaluation) will help prevent dosing with the 
study product in a participant who may have acquired HIV infection, minimizing the risk that resistant 
virus will emerge. In addition, if a participant has signs or symptoms consistent with acute HIV infection 
(see SSP Manual), or expresses a concern about recent HIV acquisition, HIV testing will be performed 
using an RNA test that, in the opinion of the IoR or designee, is able to detect early HIV infection. 
Whenever possible, an assay that is US FDA-cleared for early HIV diagnosis, such as the Aptima HIV-1 
RNA Qualitative Assay, should be used.   
Regardless of whether HIV RNA testing is used for diagnostic purposes, HIV acquisition after study 
enrollment must be confirmed in all cases using two independent samples collected on different days.   

 
HPTN 084-01, FINAL Version 1.0 
 
45 of 117 
14 October 2019 
Participants who have any reactive or positive HIV test result during follow-up visits will have further 
testing to confirm infection, as described in the SSP Manual and Appendix II. Study product will be 
withheld while this further testing is performed. 
Additional samples from participants with confirmed HIV infection may be sent to a local laboratory for 
resistance testing to assist with clinical management (results from resistance testing performed in local 
laboratories should not be reported to the HPTN SDMC or the HPTN LC). If a participant has a reactive 
or positive HIV test, the participant will not receive additional doses of study products pending further 
direction regarding testing and continued participation in the study from designated study team 
members, including the HPTN LC and the CMC. Refer to the SSP Manual for instructions further 
information. 
Step 1 – Oral Phase 
Participants with confirmed HIV infection prior to receipt of their first injection will have oral study 
product permanently discontinued and will be transitioned to local HIV-related care and terminated from 
the study.  
Step 2 – Injection Phase 
Participants with confirmed HIV infection during Step 2 will not receive additional injections and will 
be followed per the SOE in Appendices II and III quarterly for 48 weeks. In addition, sites will have a 
standard operating procedure (SOP) that outlines a plan to facilitate immediate initiation of non-study 
ART and link with appropriate HIV services in the event that a participant becomes HIV-infected during 
any Step of the study, and in particular during Step 2 of the study, to prevent emergence of drug 
resistance. Participants who seroconvert will be referred for care; sites will not be responsible for the 
actual provision/payment of ART. Neither ART nor funds for provision of ART will be provided by the 
study. 
Step 3 – Follow-up Phase 
Participants with confirmed HIV infection during Step 3 will not receive oral 
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) and will be followed per 
the SOE in Appendix III quarterly through study exit. In addition, sites will have a standard operating 
procedure (SOP) that outlines a plan to facilitate immediate initiation of non-study ART and link with 
appropriate HIV services in the event that a participant becomes HIV-infected during any Step of the 
study, and in particular during Step 2 of the study, to prevent emergence of drug resistance. Participants 
who seroconvert will be referred for care; sites will not be responsible for the actual provision/payment 
of ART. Neither ART nor funds for provision of ART will be provided by the study. 
 
5.12 
STIs 
Testing for Neisseria gonorrhoeae (GC)/Chlamydia trachomatis (CT)and syphilis will occur throughout 
the study. Testing will be performed at local laboratories. Symptomatic screening for STIs beyond what 
is required by the protocol will be at a site’s discretion. Participants will be referred for treatment of 
STIs as per local standard of care.   
5.13 
HBV and HCV 
Testing for HBV and HCV will be performed at Screening (HBsAg and HCAb). Persons positive for 
these tests will not be enrolled in the study and will be referred to their primary provider for 
management. Participants will be tested for Hepatitis B surface antibody (HBsAb), and Hepatitis B core 

 
HPTN 084-01, FINAL Version 1.0 
 
46 of 117 
14 October 2019 
antibody (HBcAb, total) at Screening or Enrollment. Participants who do not have evidence of immunity 
to HBV (e.g., negative HBsAb) will be offered HBV vaccination, ideally starting at week 2. For 
participants who do not have evidence of HBV immunity at Enrollment, HBV testing should be repeated 
at the discretion of the IoR or designee during the study if clinically indicated, if the participant has 
elevated AST/ALT results (elevated level at discretion of IoR or designee), or if the participant 
expresses a concern about having acquired HBV infection after enrollment. Refer to the SSP Manual for 
persons who have a positive result for HBcAb (total) only.      
For enrolled individuals, HCV antibody testing will be performed at scheduled visits while on Step 2 
(see Appendix II). Incident HCV infection during follow-up will not mandate discontinuation of study 
product absent other requirements per Appendix VI - Toxicity Management.       
5.14 
Contraception 
Contraception Requirements 
Because oral CAB and CAB LA are investigational agents, women may not enroll if they are pregnant 
or desire to become pregnant.  Receipt of study product by participants requires use of a reliable form of 
long acting contraception during the trial and for 48 weeks after stopping the long acting injectable, or 
30 days after stopping oral study product. Study approved methods of contraception are outlined in 
Section 3.1 and are as follows: 
• Intrauterine device (IUD) or intrauterine system (IUS) that meets <1% failure rate as 
stated in the product label 
• Hormone-based contraceptive that meets <1% failure rate when used consistently and 
correctly as stated in the product label (implants or injectables only; this excludes 
combined oral contraception).  
All participants will be actively encouraged to also use condoms for prevention of HIV and other STIs.  
Contraceptive Service Provision  
Study staff will provide contraceptive services to enrolled participants throughout the duration of study 
participation. Participants must be using one of the study-approved contraceptive methods by the Week 
2 visit in Step 1 to transition to Step 2. 
Verification of Contraceptive Use 
Study staff should confirm adequate contraception at each visit. Where adequate contraception cannot be 
confirmed, and in the opinion of the investigator, early pregnancy cannot be excluded, then the 
investigator should contact the HPTN 084-01 CMC at 084-01cmc@hptn.org for further guidance.  
All participants who are not currently pregnant and decide to discontinue long acting contraception for 
any reason will immediately discontinue study product (oral CAB or CAB LA injections). In all such 
cases, contact the HPTN 084-01 CMC at 084-01cmc@hptn.org for further guidance. 
5.15 
Pregnancy 
Participants are assessed for pregnancy throughout Steps 1, 2 and 3 as specified in the schedules of 
evaluation. Participants with a positive pregnancy test during a study visit or as reported by the 

 
HPTN 084-01, FINAL Version 1.0 
 
47 of 117 
14 October 2019 
participant between study visits must be reported to the CMC within seven days of site awareness. 
Administration of study product (oral CAB or CAB LA injections) will be held immediately and open 
label TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) offered. 
Confirmation of pregnancy at a subsequent visit at least 4 weeks after the initial pregnancy test is 
required.  
 
All participants who are confirmed pregnant must be referred for an Ultrasound and evaluation by an 
obstetric specialist at about 12-14 weeks gestational age, for other testing, counseling, and management. 
Further biochemical blood tests may be done as indicated.  The preceding services will be covered by 
the study. All findings and pregnancy outcomes will be collected and reported. The site IoR or designee 
will refer pregnant participants to all applicable pregnancy-related services and will provide a letter to 
obstetric services detailing participation in the trial; however, sites will not be responsible for paying 
for pregnancy-related care. The site IoR or designee will counsel any participants who become pregnant 
regarding possible risks to the fetus according to site-specific SOPs.  
 
Confirmed Pregnancies in Step 1 
These participants will permanently discontinue oral CAB and will not transition to Step 2. They will 
skip to Step 3, be provided open label TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) as PrEP and be reviewed every 12 weeks until delivery. If pregnancy is not confirmed on 
subsequent testing, Step 1 participants will exit the study. Site staff will refer to their SOP for detailed 
management. 
Confirmed Pregnancies in Steps 2 and 3 
Participants in Step 2 with confirmed pregnancy will permanently discontinue CAB LA injections and 
transition to Step 3 to be followed by the study every 12 weeks for 48 weeks after the last CAB LA 
injection or delivery whichever comes last. Open label TENOFOVIR/EMTRICITABINE (TRADE 
NAME: TDF/FTC, TRUVADA®)will be provided for 48 weeks after the last CAB injection. Site staff 
will refer to their SOP for detailed management.  
5.16 
Behavioral and Acceptability Assessments 
Behavioral assessment questions have been previously used either in adolescent biomedical prevention 
trials or in the Phase III adult trials of cabotegravir.  Behavioral assessment areas include sexual risk 
behavior, substance use, study product adherence and stigma associated with HIV and prevention 
technologies. 
Acceptability assessments of CAB LA will be administered via brief behavioral surveys.  The surveys 
will include, but not be limited to, questions about participants’ attitudes/beliefs towards CAB LA as 
well as product and study-related motivations. All measures will be programmed into CASI. 
5.17 
Interim Contacts and Visits 
Interim contacts and visits (those between regularly scheduled follow up visits) may be performed at 
participant request or as deemed necessary by the investigator or designee at any time during the study.  

 
HPTN 084-01, FINAL Version 1.0 
 
48 of 117 
14 October 2019 
Some interim visits may occur for administrative reasons. For example, the participant may have 
questions for study staff. Interim visits at which no data are collected are not documented on CRFs. 
Other interim contacts and visits may occur in response to AEs experienced by study participants. When 
interim contacts or visits are completed in response to participant reports of AEs, study staff will assess 
the reported event clinically, record the event on the CRF, and provide or refer the participant to 
appropriate medical care.   
 
5.18 
Criteria for Early Termination of Study Participation 
Participants may voluntarily withdraw from the study for any reason at any time. Site IoRs may, with 
the agreement of the CMC, Protocol Chairs, DAIDS MO, and study statistician, withdraw participants 
before their scheduled termination visit to protect their safety, the safety of the staff, and/or if 
participants are unable or unwilling to comply with study procedures. Participants also may be 
withdrawn if the study sponsors, government or regulatory authorities (including the OHRP and US 
FDA), or site IRBs/ECs or, other regulatory bodies or ViiV terminate the study prior to its planned end 
date. Study staff will record the reason(s) for all withdrawals in participants’ study records. 
 
 SAFETY MONITORING AND AE REPORTING 
6.1 AE Definition and Reporting 
An AE is defined as any untoward medical occurrence in a clinical research participant administered an 
investigational product and which does not necessarily have a causal relationship with the 
investigational product. As such, an AE can be an unfavorable or unintended sign (including an 
abnormal laboratory finding, for example), symptom or disease temporally associated with the use of an 
investigational product, whether or not considered related to the product. 
Study participants will be provided a 24-hour telephone number and contact information and instructed 
to contact the study clinician to report any AEs they may experience. For life-threatening events, they 
will also be instructed to seek immediate emergency care. Where feasible and medically appropriate, 
participants will be encouraged to seek evaluation where the study clinician is based, and to request that 
the clinician be contacted upon their arrival. With appropriate permission of the participant, whenever 
possible, records from all non-study medical providers related to AEs will be obtained and required data 
elements will be recorded on study CRFs. All participants reporting an AE will be followed clinically, 
until the AE resolves (returns to baseline) or stabilizes. 
Study site staff will document in source documents and the appropriate CRF all AEs (Grade 1 and 
higher, and any AE that leads to a study product hold (temporary or permanent) will be captured on 
CRFs) reported by or observed in enrolled study participants, regardless of severity and presumed 
relationship to study product. AE severity will be graded per the DAIDS Table for Grading Adult and 
Pediatric Adverse Events, Corrected Version 2.1, July 2017. This version will be used for the entire 
duration of the study. 
The AE reporting period for this study is from Enrollment (Week 0) until follow-up in the study ends. 
Relatedness is an assessment made by a study clinician of whether or not the event is related to the study 
agent. The relationship of all AEs to study product will be assessed as specified in Version 2.0, January 
2010 of the DAIDS EAE Reporting Manual.   

 
HPTN 084-01, FINAL Version 1.0 
 
49 of 117 
14 October 2019 
The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected 
Version 2.1, July 2017, will be used for the entire duration of the study for determining and reporting the 
severity of AEs. The DAIDS grading table is available on the DAIDS RSC website at 
https://rsc.niaid.nih.gov/clinical-research-sites/daids-adverse-event-grading-tables.  
6.2 EAE Reporting 
After the protocol-defined AE reporting period, unless otherwise noted, only SUSARs as defined in 
Version 2.0 of the EAE Manual will be reported to DAIDS if the study staff become aware of the events 
on a passive basis (from publicly available information). 
Requirements, definitions, and methods for expedited reporting of AEs are outlined in Version 2.0 of the 
DAIDS EAE Manual, which is available at .https://rsc.niaid.nih.gov/clinical-research-sites/manual-
expedited-reporting-adverse-events-daids.  
The study agents for the purposes of EAE reporting are: Oral CAB 30 mg oral tablet; CAB LA 
injectable suspension 3 mL (600 mg) intramuscular (IM) injectable suspension. Reporting to DAIDS 
The DAIDS Adverse Event Reporting System (DAERS), an internet-based reporting system, must be 
used for EAE reporting to DAIDS. In the event of system outages or technical difficulties, EAEs may be 
submitted via the DAIDS EAE form. For questions about DAERS, please contact 
CRMSSupport@niaid.nih.gov. Site queries may also be sent with the DAERS application itself. 
If the DAERS website or site internet is non-functional, sites will submit expedited AEs by documenting 
the information on the current DAIDS EAE form. This form is available on the DAIDS RSC website: 
https://rsc.niaid.nih.gov/clinical-research-sites/paper-eae-reporting. For questions about EAE reporting, 
please contact the DAIDS RSC at DAIDSRSCSafetyOffice@tech-res.com. 
 Reporting Requirements for This Study 
The SAE Reporting Category, as defined in Version 2.0 of the DAIDS EAE manual, will be used for 
this study (the definition of an SAE is also included in the manual).   
In addition to SAEs, sites will report in an expedited manner the following results:   
• ALT ≥ 3xULN AND total bilirubin ≥ 2xULN (must be both in order to require 
expedited reporting) 
• Any seizure event 
These reporting requirements are for each study participant from Enrollment (Week 0) until follow-up in 
the study ends. After this time, sites must report serious, unexpected, clinical suspected adverse drug 
reactions if the study site becomes aware of the event on a passive basis, i.e., from publicly available 
information. 
The study agents for the purposes of EAE reporting are: Oral CAB 30 mg oral tablet; CAB LA 
injectable suspension (200 mg/mL).  
In addition to submitting EAE information to the DAIDS Safety Office via DAERS, the site investigator 
may be required to submit AE and EAE information to local regulatory agencies or other local 
authorities. 

 
HPTN 084-01, FINAL Version 1.0 
 
50 of 117 
14 October 2019 
Information on Grade 1 and higher AEs will be included in reports to the US FDA, and other 
government and regulatory authorities as applicable. Site staff will report information regarding AEs to 
their IRB in accordance with all applicable regulations and local IRB requirements. 
6.3 Safety Monitoring 
Two hundred and thirty (n=230) healthy participants from completed studies have received single or 
repeat doses of CAB LA in Phase 1 studies at doses ranging from 100-800 mg administered as single or 
split IM or SC injections. In the Phase 1 program, to date there have been no drug-related Grade 3 or 
Grade 4 clinical AEs and only one participant has been withdrawn from dosing due to mild and transient 
rash. Injection site reactions (ISR) occurred in the majority of participants following IM (77% with any 
ISR) dosing, however, the reactions were mild and moderate (overall ISR Grade 2: 14% in IM without 
any Grade 3 or 4 ISRs).34 ISRs related to CAB LA injection were common but generally mild (IM: 86%, 
SC: 99%) with no Grade 3 ISR AEs in Phase 1 studies. The most frequent ISRs for IM dosing were pain 
(71%), erythema (9%) and nodules (7%).  Median IM ISR durations were approximately 5 days for pain 
and erythema, and approximately 22 days for nodules.34  
AEs were reported at all studied doses. The most frequent (>5%) non-ISR AEs were headache (overall 
rate of 16%: 10% in oral and 27% in LA) which occurred more frequently than in placebo subjects 
(11%) and upper respiratory tract infection (overall rate of 6%: 2% in oral and 12% in LA) versus none 
in placebo subjects. CAB was well tolerated across all studies with an overall incidence of 13% of any 
drug-related AEs and few drug related withdrawals. 
The ECLAIR study, conducted at 10 US sites, screened 205 individuals in order to enroll and randomize 
127 HIV-uninfected low-risk men. Participants received daily oral CAB 30 mg or daily oral placebo in a 
randomized 5:1 ratio during the 4-week oral lead-in phase.32 One participant randomized to active study 
product (oral CAB and CAB LA) withdrew prior to the oral lead-in due to being incarcerated. During 
the oral lead-in, 11 participants withdrew prior to their first injection, all of whom were randomized to 
CAB LA, seven for AEs and four for other reasons. Ninety-four (94) participants received at least one 
injection of CAB LA 800 mg and 21 participants received at least one injection of placebo. Of those that 
started injections 95% (20 of 21) of those randomized to placebo and 93% (87 of 94) of those 
randomized to CAB LA completed all three injections. The participant in the placebo arm who did not 
complete all three injections reached a protocol-defined stopping criteria (he acquired HIV infection 
after his second injection). Four participants on the CAB LA arm withdrew after their second injection, 
citing injection tolerability as a primary reason. Three other participants in the injection phase 
discontinued study participation for non-AE and non-injection-related reasons. 
Fifteen participants experienced a Grade 1 or higher ALT and 14 experienced a Grade 1 or higher AST. 
There were no Grade 3 or 4 ALT elevations. AE events leading to withdrawal included transient 
neutropenia (three participants), transiently elevated CPK (three participants), and fatigue (one 
participant). Two SAEs were reported, one deep vein thrombosis on placebo that was considered 
possibly drug-related and one appendicitis on CAB LA that was not considered drug related. Eighteen 
participants reported Grade 3 ISR pain.  
Grade 4 treatment emergent CPK elevations with concomitant AST and/or ALT elevations were noted 
in four participants at the Week 4 visit, leading to early withdrawal in three participants.   One of the 
four participants described a new rigorous exercise regimen prior to the Week 4 study visit; a second of 
these events resolved despite ongoing exposure to study product. All four Grade 4 abnormalities were 
resolving at one-week follow-up visits and have subsequently returned to normal off study product.  

 
HPTN 084-01, FINAL Version 1.0

14 October 2019 
Close cooperation between the Protocol Chair, study site Investigator(s), DAIDS Medical Officer, LOC 
Clinical Research Manager, SDMC Biostatistician, SDMC Clinical Affairs Staff, HPTN LC, and other 
study team members will be necessary in order to monitor participant safety and to respond to 
occurrences of toxicity in a timely manner.  
The study site Investigators are responsible for continuous close monitoring and management of AEs. 
Sites are required to have detailed SOPs describing methods for AE reporting and toxicity management 
to ensure that AEs are reported and managed in accordance with the protocol and for alerting the CMC 
(outlined below) if unexpected concerns arise. 
A sub-group of the Protocol Team, including the Protocol Chair, DAIDS Medical Officer, and other site 
investigators will serve as members of the CMC. The CMC provides support to sites regarding 
individual participant clinical management (e.g., questions related to eligibility, toxicity management, 
clinical holds of study drug, etc.).  
6.4 Clinical Data Review 
A multi-tiered safety review process will be followed for the duration of this study. The study site 
investigators are responsible for the initial evaluation and reporting of safety information at the 
participant level, and for alerting the CMC if unexpected concerns arise.   
Participant safety data is also monitored by the SDMC Clinical Affairs staff who review incoming safety 
data for completeness and consistency on an ongoing basis. Events identified as questionable, 
inconsistent, or unexplained will be queried for verification.  
AE reports submitted in an expedited manner to the DAIDS Safety Office will be forwarded to the 
DAIDS Medical Officer for review and possible reporting to the FDA as a Safety Report. 
The SDMC will prepare routine reports of study conduct for the Safety Monitoring Committee (SMC), 
which will meet by conference call approximately every 6 months and will review accrual and retention 
data, as well as other aspects of study conduct. More frequent or ad hoc reviews of safety data may be 
conducted by the SMC as needed. 
This study also will be monitored by a NIAID Data and Safety Monitoring Board (DSMB), along with 
the parent protocols, which will meet at least annually to review safety and efficacy data.  More frequent 
or ad hoc reviews of safety data may be conducted by the DSMB as needed.  
6.5 Social Harms and Social Benefits Reporting 
It is possible that participants' involvement in the study could become known to others, and that a social 
harm may result (i.e., because participants could be perceived as being HIV-infected or at "high risk" for 
HIV infection). For example, participants could be treated unfairly, or could have problems being 
accepted by their families and/or communities. These are social harm events. Social harms events are 
those negative events that a participant reports as affecting them as a result of being involved in a 
research study, not the researcher’s opinion of how they perceive an event has affected a participant. A 
social harm that is reported by the participant and judged by the IoR/designee to be serious or 
unexpected will be reported to the responsible site’s IRBs at least annually, or according to their 
individual requirements.   

 
HPTN 084-01, FINAL Version 1.0 
 
52 of 117 
14 October 2019 
Social harms and benefits will be collected and reported on CRFs during regular visits. In the event that 
a participant reports a social harm, every effort will be made by study staff to provide appropriate care 
and counseling to the participant as necessary, and/or referral to appropriate resources for the safety of 
the participant. Each site will provide such care and counseling in accordance with standardized 
guidance in the SSP Manual. While maintaining participant confidentiality, study sites may engage their 
Community Advisory Board in exploring the social context surrounding instances of social harms, to 
minimize the potential occurrence of such an impact. In addition to social harms, any benefits of study 
participation, which are outcomes reported by the participant as a benefit to them as a result of being in 
the study (e.g., improvement in relationships), will also be collected and reported into the database. 
 
6.6 Critical Events Reporting 
Per the DAIDS policy on Identification and Classification of Critical Events, a critical event is defined 
as an unanticipated study-related incident that is likely to cause harm or increase the risk of harm to 
participants or others or has a significant adverse impact on study outcomes or integrity. All such events 
must be reported following procedures specified in the DAIDS Critical Events Manual, available at: 
https://www.niaid.nih.gov/sites/default/files/criticaleventsmanual.pdf.  
 
 STATISTICAL CONSIDERATIONS 
7.1 Review of Study Design 
This is a single arm, open label, safety, tolerability, and acceptability study of CAB LA for prevention of 
HIV-acquisition in sexually-active, HIV-uninfected adolescents (<18 years old at time of enrollment).  
The study includes a 5-week oral CAB 30mg QD safety lead-in followed by a series of 5 intramuscular 
(IM) injections of 3 mL (600 mg) of CAB LA administered at 8-week intervals after a 4-week loading 
dose (injections at weeks 5, 9, 17, 25 & 33). Follow up on study product (oral and injectable) will occur 
for 34 weeks.  All participants who have received at least one injection will be followed for 48 weeks 
after their last injection. Waning levels of cabotegravir (the PK tail) will be covered with locally sourced 
oral TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) for daily use for 48 
weeks.  
The sample size for this study will be set to enroll approximately 50 participants. The sample size for 
this protocol (n=50) is the number of participants agreed upon by the industry sponsor and regulators in 
order to provide supplementary safety and behavioral data on adolescents in collaboration with the 
HPTN 083 and HPTN 084 adult trials. The primary aims of the study are focused on safety, tolerability, 
and acceptability of this long-acting product.  
Finally, in-depth qualitative interviews will be conducted with 10 participants total across all sites after 
Week 34 to explore issues of acceptability and preference for oral tablets and/or injections. Additionally, 
up to 10 parents/guardians of participants (total, across all sites) will be asked to participate in in-depth 
interviews to explore facilitators and barriers to adolescent enrollment in biomedical clinical trials.  
7.2 Endpoints 
 Primary Endpoints 

 
HPTN 084-01, FINAL Version 1.0 
 
53 of 117 
14 October 2019 
• Safety endpoint: Proportion of participants experiencing any Grade 2 or higher 
clinical adverse events (AEs) and laboratory abnormalities among participants who 
receive at least one injection of CAB LA 
• Tolerability endpoint: Proportion of participants who receive at least 1 injection and 
who discontinue receiving injections prior to the full course of injections due to 
intolerability of injection, frequency of injections or burden of study procedures 
• Acceptability endpoints: Proportion of participants who complete all scheduled 
injections and proportion of participants who receive at least one injection whom 
would consider using CAB LA for HIV prevention in the future  
 
 Secondary Endpoints 
• Plasma CAB pharmacokinetics  
• Proportion of participants experiencing Grade 2 or higher clinical AEs and laboratory 
abnormalities in the 48 weeks following final injection  
• Proportion of injection visits that occurred “on-time”  
• Change from enrollment of self-reported sexual behavior (number of sexual partners, 
increased episodes of unprotected vaginal or anal intercourse) during the study period  
7.3 Sample Size  
The sample size for this protocol (n=50) is the number of participants agreed upon by the industry 
sponsor and regulators in order to provide supplementary safety and behavioral data on adolescents in 
collaboration with the HPTN 083 and HPTN 084 adult trials. The goal of the safety evaluation for this 
study is to identify safety concerns associated with CAB LA. 
Since each of the primary endpoints is a proportion, Table 2. Width of 95% confidence interval for 
estimated proportion as a function of the true proportion, assuming a sample size of 50. shows the 
precision (confidence interval width) that will be obtained for each endpoint with a sample size of 50.

7.4 Randomization 
There is no treatment randomization due to this study being a single arm, open label trial. 
7.5 Blinding 
 Participants and site staff will be unblinded throughout the trial. 
7.6 Data and Safety Monitoring Analysis 
 Study Monitoring Committee  
NIAID DSMB oversight is planned for this study. Monitoring guidance will be detailed in a separate 
Interim Monitoring Plan. In addition, approximately every six months the HPTN SMC will conduct 
interim reviews of study progress, including rates of participant accrual, visit retention, and completion 
of primary and main secondary endpoint collection. The frequency and content of SMC reviews will be 
determined prior to the start of the study as outlined in the HPTN Manual of Procedures (MOP). 
 Primary Analyses 
All participants who receive at least one injection will contribute to the primary analyses. The safety and 
tolerability will be analyzed in aggregate. When the use of descriptive statistics to assess group 
characteristics or differences is required, the following methods will be used: for categorical variables, 
the number and percent in each category; for continuous variables, the mean, median, standard 
deviation, quartiles and range (minimum, maximum).  
 Safety Endpoints 
The primary safety analysis will include Grade 2 or higher clinical and laboratory events that occur from 
the initial injection to 48 weeks after the last injection among participants who receive at least one 
injection. Secondary safety analyses will include the same definition applied over the oral phase only 
(week 0 to week 4) and the aggregate oral+injectable+follow-up period. 
To assess safety, the number and the percent of participants experiencing each safety endpoint will be 
tabulated. Each participant will contribute once in each category (for example, only for the highest 
severity AE for each participant) for the calculation of event rates. Exact binomial confidence intervals 
will be calculated for each safety endpoint.   
 Injection Site Reaction (ISR)  
The number and percentage of participants experiencing each type of injection site reaction sign or 
symptom will be tabulated by severity. For a given sign or symptom, each participant’s ISR will be 
counted once under the maximum severity for all injection visits as well as by each successive injection. 
In addition, we will report the proportion of injections (over all participants) that resulted in an ISR. A 
95% CI (using a robust variance) will be computed. 
 AEs and Serious Adverse Events (SAEs) 

 
HPTN 084-01, FINAL Version 1.0 
 
55 of 117 
14 October 2019 
AEs will be tabulated using MedDRA preferred terms. The number and percentage of participants 
experiencing each specific AE (All AEs, Grade 2 or higher, and SAEs) will be tabulated by severity and 
by relationship to study product. For the calculations in these tables, each participant’s AEs will be 
counted once as the maximum severity and relationship to study product. AEs leading to temporarily or 
permanently stopping drug will also be summarized. AEs will be summarized for those that are 
treatment emergent during LA dosing separately from those that are treatment emergent during oral 
dosing and also for those that are treatment emergent across the entire treatment phase of the study 
(combining both LA and oral dosing).   
A listing of EAEs reported to the DAIDS RSC Safety Office will provide details of the events including 
severity, relationship to study product, time between onset and last injection, number of injections 
received, and a summary of the event. 
 Tolerability 
To assess tolerability, the number and the percent of participants who receive at least one injection and 
discontinue receiving injections prior to the full course due to intolerability of injection (including but 
not limited to ISR), frequency of injections, or burden of procedures or any AE will be tabulated. 
 Acceptability 
To assess acceptability, the number and percentage of participants who complete all scheduled injections 
will be described. Additionally, the number and the percent of participants who receive at least one 
injection that would consider using CAB LA for HIV prevention in the future will be tabulated. 
Acceptability will be assessed by age and in aggregate.  
Acceptability of CAB LA will also be assessed through administration of brief behavioral surveys and 
qualitative interviews.  The surveys will include, but not be limited to, questions about participants’ 
attitudes/beliefs towards CAB LA; product and study-related motivations. In addition, a subset of 
participants will be invited to take part in qualitative assessments of acceptability in order to provide 
more holistic and contextualized information on motivations, attitudes and experiences using injectable 
PrEP, reasons for and circumstances related to product and/or study discontinuation, and future 
intentions related to PrEP use. 
A subset of 10 willing participants will complete an in-depth interview (IDI) to be scheduled after the 
Week 34 visit. In addition, up to 10 parents of participants will be invited to participate in in-depth 
interviews that will explore facilitators and barriers to adolescent participation in biomedical HIV 
prevention trials. When conducting a qualitative exploration, the sampling method should be designed to 
include a range of possible perspectives on the phenomenon under study, thus ideal qualitative samples 
are purposive in nature. For this study, we will utilize a purposive sampling strategy, which will allow 
for consideration of the concepts of range, saturation/redundancy, and stratification in the sampling 
frame. We will ask sites to identify potential participants as well as parents/caregivers who would be 
interested in and comfortable with sharing their experiences with the study product as well as study 
procedures. Data on acceptability and factors affecting adherence will be collected during the IDI, 
including questions that explore the use and the acceptability of both the oral and injectable CAB, along 
with examination of preference for pills or injections. Additional interview topics will include 
challenges to study participation as well as product use. We will also discuss with participants the 
acceptability of parental involvement in the consent process.

14 October 2019 
These interviews will be conducted by a trained study interviewer and will follow a semi-structured 
questionnaire guide. They will be approximately 30-60 minutes in duration and will be conducted in an 
area that maximizes participant privacy and confidentiality. Participants may be compensated for the 
completion of the in-depth interview. These interviews will be recorded for analysis and transcribed. 
 
 Local laboratory values  
Box plots of local laboratory values will be generated for baseline values and for values measured 
during the course of the study by visit. Each box plot will show the first quartile, the median, and the 
third quartile. Outliers will also be plotted. If appropriate, horizontal lines representing boundaries for 
abnormal values will be plotted.  
The number (percentage) of participants with local laboratory values recorded as meeting Grade 2 AE 
criteria or above as specified in the DAIDS AE Grading Table will be tabulated for follow-up time 
points. Reportable clinical laboratory abnormalities without an associated clinical diagnosis will also be 
included in the tabulation of AEs described above. 
7.7 Secondary Analyses 
 Sexual Risk Behaviors 
Change in sexual risk behavior (number of sexual partners, episodes of unprotected anal and/or vaginal 
intercourse) during the injection phase will be measured by summarizing the change from baseline by 
visit. Sexual risk behavior will be analyzed in aggregate.   
 Plasma Drug-Level Concentrations  
Descriptive analyses of plasma concentration of CAB LA will be performed using mean, median, 
standard deviation, coefficient of variation (%CV) and range, for example. Graphical displays of the 
data based on appropriate techniques (e.g., boxplots, histograms, kernel density estimates, probability 
plots, scatterplots) will be generated to visually explore distributional properties of the data. Statistics 
and graphical displays will be produced for plasma concentrations within and across timepoints. In 
addition, proportion of participants with plasma CAB concentrations <LLQ, between LLQ and PA-
IC90, 1-4X PA-IC90, and >4X PA-IC90 will be calculated at pre-specified time points after the final 
injection. 
In addition to concentration summaries, parameters may be derived by non-compartmental methods.  
Details of the analysis will be described in the study Reporting and Analysis Plan (RAP), separately.   
7.8 Qualitative Analysis  
All qualitative interviews will be conducted by trained interviewers, digitally-recorded, transcribed and 
translated into English (as needed), and then uploaded into a qualitative software analysis program (such 
as NVivo 12.) The Protocol Chair and her team will follow a process of reading, coding, data display 
and data reduction in order to explore in greater depth participants’ attitudes towards and experiences 
with the product. Data coding and analysis will be both iterative and interactive processes. The team will 
first read all interview transcripts in order to increase familiarity with the data. Next, the team will 
assign a priori codes and create emergent codes. Transcripts will then be re-read to create pattern codes 
that connect subsequent concepts under larger headings. Consistent patterns in meaning, concepts, and 
themes across all interviews will be identified, and detailed memos/data matrices will be developed to 

 
HPTN 084-01, FINAL Version 1.0 
 
57 of 117 
14 October 2019 
examine how participants’ perceptions related to product use (i.e., ease of use, perceived efficacy, side 
effects) and to trial participation (i.e., motivations for participation, interactions with trial staff, impact 
on partner, parent or other social relationships) influence acceptability and interest in future use of an 
injectable PrEP product. Comparative analyses will be conducted to clarify differences that may exist 
for any subgroups of adolescents. Coding and analytic activities will be discussed during qualitative data 
analysis meetings, and discrepancies in coding and interpretation will be resolved through consensus. A 
similar analytic approach will be followed for parent/guardian interviews.  
 
 HUMAN SUBJECTS CONSIDERATIONS 
8.1 Ethical Review 
This protocol and the template informed consent form contained in Appendix IV— and any subsequent 
modifications — will be reviewed and approved by the HPTN Scientific Review Committee (SRC) and 
DAIDS Prevention Science Review Committee (PSRC) with respect to scientific content and 
compliance with applicable research and human subjects regulations.  
The protocol, site-specific informed consent form, participant education and recruitment materials, and 
other requested documents — and any subsequent modifications — also will be reviewed and approved 
by the ethical review bodies responsible for oversight of research conducted at the study site.  
Subsequent to initial review and approval, the responsible IRBs/ECs will review the protocol at least 
annually. The Investigator will make safety and progress reports to the IRBs/ECs at least annually, and 
within three months of study termination or completion. These reports will include the total number of 
participants enrolled in the study, the number of participants who completed the study, all changes in the 
research activity, and all unanticipated problems involving risks to human subjects or others. Study sites 
are responsible for the submission of continuing review to the DAIDS Protocol Registration Office 
(PRO), in accordance with the current DAIDS Protocol Registration Policy and Procedure Manual. 
8.2 Informed Consent 
This section provides details regarding informed consent and assent requirements and procedures for 
adolescents. Site investigators and their designees will be required to determine participant age and 
ability to provide independent informed consent for study participation consistent with IRB/EC policies 
and procedures. Each site must establish SOPs, roles, and responsibilities for completing these 
determinations, and study staff involved in completing these determinations must have documented 
training in the relevant policies and procedures prior to initiating study activity.  
Written informed consent and written assent will be obtained for study participation as follows:  
• If the potential participant is of legal age or otherwise able to provide independent 
informed consent as determined by site SOPs, local laws and regulations, and 
consistent with site IRB/EC policies and procedures: The potential participant must 
provide written informed consent for study participation.  
• If the potential participant is not of legal age to provide independent informed 
consent as determined by site SOPs and local laws and regulations: Parent, legal 
guardian, or other legally authorized representative must provide written informed 

 
HPTN 084-01, FINAL Version 1.0 
 
58 of 117 
14 October 2019 
permission for study participation and the potential participant must provide written 
assent for study participation.  
Note: IRB/EC risk determinations will guide whether the consent of one or both parents may be required 
for this study. All IRB/EC requirements must be followed.  
• During study follow-up, if such a participant reaches the legal age and is able to 
provide independent informed consent as determined by site SOPs: The participant 
must then provide written informed consent to continue study participation. 
Written informed consent and assent (as applicable) for participation will be obtained before any study-
specific procedures are performed. The informed consent process will include information exchange, 
detailed discussion, and formal assessment of understanding of all required elements of informed 
consent, including the potential risks, benefits, and alternatives to study participation. The process will 
describe what is known about the safety and tolerability of the study products and participants and 
parents/guardians will be extensively counseled on the importance of adherence to the study product 
regimen and study visit schedule. The approach adopted by the site will be tailored to adolescents, 
utilizing a variety of supporting materials, and may be spread over multiple sessions to foster sufficient 
understanding of the study prior to making the decision to take part.   
Appendix VI provides sample informed consent/assent forms for obtaining parent or legal guardian 
permission and adolescent assent for study participation. Appendices VII, VIII and IX provide sample 
informed permission and assent forms for specimen storage and future use, adolescent qualitative 
interviews and parent/legal guardian interviews. All sample informed consent and assent forms may be 
modified by sites to meet IRB/EC requirements. If the participant, parent, or guardian (as applicable) is 
unable to read, the process for consenting illiterate participants, as defined or approved by the local 
IRB/EC, should be followed.  
As indicated above, parental consenting requirements at each site will depend on the IRB/EC risk 
determination and all IRB/EC requirements will be followed. Participants enrolling in the study as 
minors will generally require permission from a parent or guardian.  
In general, each participant is expected to take part in the informed consent process with his or her 
parent or legal guardian, and both the assent of the participant and the permission of the parent or legal 
guardian will be required for all consent decisions. For example, if the participant does not provide 
assent, or the parent or legal guardian does not provide permission, the participant will not be enrolled in 
the study.  
Should the consenting parent (or guardian) of a participant no longer be available for any reason, sites 
should follow the guidelines and procedures described by their IRBs/ECs. Study sites may continue to 
provide care for the participant as needed and appropriate (outside of the study), consistent with local 
standard of care.  
Participants may also reach the legal age of consent during follow-up. In this case, written informed 
consent for continued participation will be obtained from participants once they reach legal age at their 
next study visit. If participants do not consent for continued study participation, they should be 
discontinued from the study.  
Each study site is responsible for developing study informed consent forms for local use that describes 
the purpose of the study, the procedures to be followed, and the risks and benefits of participation, in 

 
HPTN 084-01, FINAL Version 1.0 
 
59 of 117 
14 October 2019 
accordance with all applicable regulations. If applicable, the study site also is responsible for translating 
the template form into local languages and verifying the accuracy of the translation by performing an 
independent back-translation. 
Participants will document their provision of informed consent and assent by signing their informed 
consent forms. All participants will be offered a copy of their informed consent form. 
8.3 Incentives 
Pending IRB approval, participants will be compensated for their time and effort in this study, and/or be 
reimbursed for travel to study visits and time away from other responsibilities. This includes the time 
and effort of parents or legal guardians who bring their child to the study visits. Site-specific 
reimbursement amounts will be specified in the study informed consent forms. 
8.4 Confidentiality 
All study-related information will be stored securely at the study site. All participant information will be 
stored in locked file cabinets in areas with access limited to study staff. All laboratory specimens, 
reports, study data collection, process, and administrative forms will be identified by a coded number 
only to maintain participant confidentiality. All records that contain names or other personal identifiers, 
such as locator forms and informed consent forms, will be stored separately from study records 
identified by code number. All local databases will be secured with password-protected access systems. 
Forms, lists, logbooks, appointment books, and any other listings that link participant ID numbers to 
other identifying information will be stored in a separate, locked file in an area with limited access. 
Participant’s study information will not be released without the written permission of the participant, 
except as necessary for monitoring by the NIAID and/or its contractors; representatives of the HPTN 
LOC, HPTN SDMC, and/or HPTN LC; site IRBs/ECs; other local, US, or international regulatory 
authorities; the government or regulatory authorities (including the OHRP and US FDA); or ViiV.  
8.5 Communicable Disease and Statutory Rape Reporting Requirements 
Study staff will comply with all applicable local requirements to report communicable diseases 
identified among study participants to local health authorities and will comply with applicable local laws 
regarding the reporting requirements of sexual activity of minors that can be considered statutory rape. 
Participants will be made aware of all reporting requirements during the study informed consent process. 
8.6 Study Discontinuation 
The study also may be discontinued at any time by NIAID, the HPTN, government or regulatory 
authorities (including the OHRP and US FDA), site IRBs/ECs or if appropriate, the SAHPRA, or ViiV. 
This would be done primarily due to safety concerns for the participants or due to an earlier-than-
expected indication of product efficacy or study futility. 
 
 LABORATORY SPECIMENS AND BIOHAZARD CONTAINMENT 
Laboratory procedures are described below and in Appendices I and II. Refer to Appendix IV for any 
participant who has a reactive or positive HIV test after Enrollment.

9.1 Local Laboratory Specimens 
The following types of tests will be performed at the local laboratory:  
• HIV testing (see SSP Manual) 
• Pregnancy testing (see below) 
• HBV and HCV testing to include HBsAg, HBsAb, HBcAb (total), HCV antibody tests   
• Complete blood count (CBC) with differential  
• Chemistry testing (blood-urea nitrogen (BUN) or urea, creatinine, CPK, glucose, 
calcium, phosphorous, amylase, lipase) 
• LFTs (AST, ALT, TBili, alkaline phosphatase) 
• Fasting lipid profile (total cholesterol, high-density lipoprotein (HDL), triglycerides, low-
density lipoprotein (LDL)) – calculated or measured  
• Syphilis serologic testing 
• Urine (protein and glucose) 
• Vaginal swabs OR urine for GC/CT nucleic acid amplification testing (NAAT) testing  
• Plasma storage 
• DBS storage 
• HIV viral load (if HIV-infected) 
• CD4 cell count (if HIV-infected) 
• Real-time resistance testing for clinical management, if indicated and available (if HIV-
infected) 
If the HIV testing algorithm includes HIV rapid testing, that testing may be performed in the clinic or 
laboratory.  
Pregnancy testing 
All women will have a βHCG test for pregnancy (sensitivity of ≤ 25 mIU/mL) at the majority of visits. 
Pregnancy testing may be performed in the clinic or the laboratory at all visits where this testing is 
indicated. Testing may be performed using a urine, plasma, or serum sample. Continued pregnancy 
testing is not required following a confirmed (done in 4 weeks after initial positive) positive test result.  
 
Each study site will adhere to standards of good laboratory practice, the HPTN Manual of Operations 
(MOP), the SSP Manual and local SOPs for proper collection, processing, labeling, transport, and 
storage of specimens to the local laboratory. Specimen collection, testing, and storage at the local 
laboratory will be documented using the HPTN Laboratory Data Management System (LDMS) as 
described in the SSP Manual. 
All specimens will be shipped in accordance with International Air Transport Association (IATA) 
specimen shipping regulations. All shipments will be documented using the HPTN LDMS as described 
in the SSP Manual.

9.2 Stored Specimens 
Plasma will be stored at the local site throughout the study and after until discard approval is given by 
DIADS, the PI, and the HPTN LC. A subset of the stored samples will be shipped to the HPTN LC 
(located in the US) for Quality Assurance (QA) and other assessments. As indicated below, testing on 
stored samples will be performed by the HPTN LC or another laboratory designated by the HPTN LC. 
9.3 Virology 
The HPTN LC will perform QA testing, including testing to determine HIV infection status in selected 
cases. Additional assays may be performed at the HPTN LC or a laboratory designated by the HPTN 
LC. This testing may include the following tests for participants who acquire HIV infection: HIV viral 
load, HIV resistance testing, HIV subtyping, and other tests to characterize HIV viruses and/or the host 
response to HIV infection. Results will not be returned to the sites or study participants, with the 
exception of HIV diagnostic testing (if results obtained at the HPTN LC do not agree with site results).  
Resistance testing will be performed at the HPTN LC or a laboratory designated by the HPTN LC. This 
testing will be performed retrospectively at the end of the study. Results of this testing will not be 
returned to study sites. Because real-time resistance testing may be needed for clinical management in 
the event of HIV infection, each site will have an SOP as to how they will accomplish real-time local or 
regional resistance testing to assist with clinical decision making; separate specimens should be 
collected for that testing.   
9.4 Pharmacology 
Blood samples will be collected throughout the study from all participants and assayed for plasma CAB 
concentrations. PK sample times include pre-dose trough samples at W5, W9, W17, W25, and W33 
(final concentration in injection phase) and 1-week post injection samples at W6, W10, W18, W26, 
W34.  In addition, follow-up samples will be collected at +8, +24, +36 and +48-weeks following the 
final injection (Appendix II and Appendix III) and at HIV confirmatory visit (Appendix IV).   
Plasma samples will be processed and frozen locally for subsequent shipment to the HPTN LC 
following procedures outlined in the SSP Manual. Pharmacology testing will be performed at the HPTN 
LC or at an outside laboratory designated by the HPTN LC. The primary pharmacologic assessments 
will be performed using assays that have been validated and approved by the Clinical Pharmacology 
Quality Assurance (CPQA) Committee (reference assay validation report). Results will not be returned 
to the study participants or study sites. 
Plasma and DBS samples will be processed and frozen locally for subsequent shipment to the HPTN LC 
following procedures outlined in the SSP Manual. Pharmacology testing will be performed at the HPTN 
LC or at an outside laboratory designated by the HPTN LC. The primary pharmacologic assessments 
will be performed using assays that have been validated and approved by the Clinical Pharmacology 
Quality Assurance (CPQA) Committee (reference assay validation report). Results will not be returned 
to the study participants or study sites. Plasma and DBS will be collected in Step 3 and if a study 
participant seroconverts for potential pharmacologic analysis of plasma TFV and DBS TFV-DP 
concentrations, respectively, to assess PrEP adherence.   
Stored plasma may also be tested for the presence of other ARV drugs or other concomitant 
medications.

9.5 Quality Control and Quality Assurance Procedures 
Study sites will document that their laboratories are certified under the Clinical Laboratory Improvement 
Amendments Act of 1988 (CLIA-certified) and/or participate in DAIDS-sponsored External Quality 
Assurance (EQA) programs. HPTN LC staff will conduct periodic visits to each site to assess the 
implementation of on-site laboratory quality control (QC) procedures, including proper maintenance of 
laboratory testing equipment and use of appropriate reagents. HPTN LC staff will follow up directly 
with site staff to resolve any QC or QA problems identified through proficiency testing and/or on-site 
assessments. 
9.6 QC for HIV Diagnostic Testing 
HIV diagnostic tests will be listed on the site Protocol Analyte List (PAL) and will be subject to review 
and approval by DAIDS and the HPTN LC. Local laboratories will perform testing for HIV diagnosis at 
Screening, Enrollment, and follow-up visits. Algorithms for HIV diagnostic testing are provided in the 
SSP Manual. 
Throughout the course of the study, the sites will ship an aliquot per visit per participant quarterly per 
the SSP. The HPTN LC, with guidance from the SDMC, will select a random sample of stored 
specimens to test for QA purposes. The total number of specimens undergoing QA testing will follow 
the QA processes as described in the HPTN MOP and at the discretion of the HPTN LC. 
The HPTN LC will test the specimens for evidence of HIV infection and compare the results of their 
tests with the results obtained by the local labs. HPTN LC staff will follow-up directly with site staff to 
resolve any QA problems identified through this process. 
9.7 Quality Assurance for General Laboratory Testing 
Local laboratories will perform hematology, chemistry, liver function, lipids, hepatitis, STI, and 
urinalysis testing as indicated in each relevant SOE. Non-US laboratories performing these tests will be 
monitored by Patient Safety Monitoring and International Laboratory Evaluation (pSMILE) and must 
demonstrate successful participation in the relevant EQA programs.  
9.8 Quality Assurance for CD4 Cell Count Testing 
Local laboratories may also perform CD4 cell count testing as indicated in Appendix II. Non-US 
laboratories performing these tests will be monitored by the DAIDS Immunology Quality Assurance 
(IQA) program and UKNEQAS program and must demonstrate successful participation in these 
programs.       
9.9 Quality Assurance for HIV RNA Testing 
Local laboratories may also perform HIV RNA/viral load testing (platform and test kit approved by the 
HPTN LC) as indicated in Appendix II or for evaluation of possible acute HIV infection. Non-US sites 
may use local laboratories for this testing. Non-US laboratories performing these tests will be monitored 
by the DAIDS Virology Quality Assurance (VQA) program and must demonstrate successful 
participation in this program.

Specimen Storage and Possible Future Research Testing 
Study sites will store specimens collected in this study at least through the end of the study (completion 
of all study-related testing, including testing at the HPTN LC). In addition, study participants will be 
asked to provide written informed consent for the collected samples to be stored after the end of the 
study, for possible future non-protocol listed testing. The specimens of participants who do not consent 
to long-term storage and additional testing will be destroyed after all of the protocol specified testing 
(including assessments at the HPTN LC) has been completed and approval from the protocol team and 
network leadership is provided.    
Samples from participants who did not successfully enroll in the study may be discarded once sample 
lists are provided by the HPTN LC in consultation with the HPTN SDMC. 
9.11 
Biohazard Containment 
As the transmission of HIV and other blood-borne pathogens can occur through contact with 
contaminated needles, blood, and blood products, appropriate blood and secretion precautions will be 
employed by all personnel in the drawing of blood and shipping and handling of all specimens for this 
study, as currently recommended by the US CDC. All infectious specimens will be transported in 
accordance with United States regulations (42 CFR 72) and in accordance with IATA. 
 
 ADMINISTRATIVE PROCEDURES 
10.1 
Protocol Registration 
Initial Registration of the protocol by the DAIDS PRO is required prior to implementation of this 
protocol. As part of this process, each site must have the protocol and protocol informed consent form(s) 
(ICFs) approved, as appropriate, by their IRB/EC and any other applicable regulatory entity (RE). Upon 
receiving final approval, sites will submit all required protocol registration documents to the DAIDS 
PRO at the RSC. The DAIDS PRO will review the submitted protocol registration packet to ensure that 
all of the required documents have been received. In the case of Initial Registration, site-specific ICFs 
WILL be reviewed and approved by the DAIDS PRO. Sites will receive an Initial Registration 
Notification from the DAIDS PRO that indicates successful completion of the protocol registration 
process. A copy of the Initial Registration Notification should be retained in the site's regulatory files. 
Following Initial Registration, any full protocol amendments require submission of a protocol 
registration packet to the DAIDS PRO as described above; however, the DAIDS PRO WILL NOT 
review and approve site-specific ICFs. Upon receiving final IRB/EC and any other applicable RE 
approval(s) for an amendment, sites should implement the amendment immediately. Sites will receive a 
Registration Notification when the DAIDS PRO receives a complete registration packet.  A copy of the 
Amendment Registration Notification should be retained in the site’s regulatory files.   
There may be cases where a site submits as their Initial Registration a protocol amendment (Version 2.0 
or higher of a protocol); in such cases, the instructions for Initial Registration will be followed. 
For additional information on the protocol registration process and specific documents required for 
initial and amendment registrations, refer to the current version of the DAIDS Protocol Registration 
Manual, which can be found at https://rsc.niaid.nih.gov/clinical-research-sites/daids-protocol-
registration-policy-and-procedures-manual.

10.2 
Study Activation 
Pending successful protocol registration and submission of all required documents, the HPTN LOC staff 
will “activate” a site. Study implementation may not be initiated until a study activation notice is 
provided to the site by the HPTN LOC. In addition, if study “activation” is determined to be necessary 
for any subsequent amendments, study implementation may not be initiated until a study activation 
notice is provided to the site by the HPTN LOC. 
10.3 
Study Coordination 
DAIDS holds the Investigational New Drug (IND) application for this study. Copies of all regulatory 
documents submitted to this IND by DAIDS will be forwarded to ViiV Healthcare for cross-referencing 
with the company’s other INDs for the study product(s). Assignment of all sponsor responsibilities for 
this study will be specified in a Clinical Trials Agreement executed between DAIDS and ViiV 
Healthcare. 
Study implementation will be directed by this protocol as well as the SSP Manual. The SSP Manual, 
which will include links to the DAIDS SOPs for Source Documentation and Essential Documents, as 
well as links to the Manual for Expedited Reporting of AEs to DAIDS and the DAIDS Toxicity Tables, 
will outline procedures for conducting study visits; data and forms processing; AE assessment, 
management and reporting; dispensing study products and documenting product accountability; and 
other study operations. 
Study CRFs will be developed by the study team and HPTN SDMC. Data will be transferred to the 
HPTN SDMC, entered, and cleaned using the HPTN SDMC Medidata Rave electronic data 
management system. Queries routinely will be generated and distributed to the study sites for 
verification and resolution. 
Close coordination between protocol team members will be necessary to track study progress, respond 
to queries about proper study implementation, and address other issues in a timely manner. Rates of 
accrual, adherence, follow-up, and AE incidence will be monitored closely by the team as well as the 
HPTN SMC. The protocol team’s CMC will address issues related to study eligibility and AE 
management and reporting as needed to assure consistent case management, documentation, and 
information-sharing across sites. 
10.4 
Study Monitoring 
On-site study monitoring will be performed in accordance with DAIDS policies. Study monitors will 
visit the site to: 
• verify compliance with human subjects and other research regulations and guidelines;  
• assess adherence to the study protocol, study-specific procedures manual, and local 
counseling practices; and 
• confirm the quality and accuracy of information collected at the study site and entered 
into the study database. 
Site investigators will allow study monitors to inspect study facilities and documentation (e.g., informed 
consent forms, clinic and laboratory records, other source documents, CRFs), as well as observe the 
performance of study procedures. Investigators also will allow inspection of all study-related 

 
HPTN 084-01, FINAL Version 1.0 
 
65 of 117 
14 October 2019 
documentation by authorized representatives of the HPTN LOC, HPTN SDMC, HPTN LC; NIAID 
and/or its contractors; site IRBs/ECs; other local or international regulatory authorities (including the 
OHRP and US FDA); or, if appropriate, ViiV. A site visit log will be maintained at each study site to 
document all visits. 
10.5 
Protocol Compliance 
The study will be conducted in full compliance with the protocol. The protocol will not be amended 
without prior written approval by the Protocol Chair and DAIDS Medical Officer. All protocol 
amendments must be submitted to and approved by the relevant IRB(s) and the DAIDS RSC prior to 
implementing the amendment. 
10.6 
Investigator's Records 
The IoR will maintain, and store in a secure manner, complete, accurate, and current study records 
throughout the study. In accordance with Federal regulations, for each of the investigational products 
tested, the IoR will retain all study records for at least two years following the date of marketing 
approval for the study product for the indication in which it was studied, or if other applicable laws, 
regulations, policies, or other requirements (e.g., State, country-specific, and local laws, and sponsor or 
institutional policies) exist, the most stringent retention period will be followed. If no marketing 
application is filed, or if the application is not approved, the records must be retained for two years after 
the US FDA is notified that the IND is discontinued, or if other applicable laws, regulations, policies, or 
other requirements (e.g., State, country-specific, and local laws, and sponsor or institutional policies) 
exist, the most stringent retention period will be followed. Study records include administrative 
documentation — including protocol registration documents and all reports and correspondence relating 
to the study, as well as documentation related to each participant screened and/or enrolled in the study. 
This includes informed consent forms, locator forms, CRFs, notations of all contacts with the 
participant, and all other source documents. 
10.7 
Use of Information and Publications 
Publication of the results of this study will be governed by HPTN policies. Any presentation, abstract, or 
manuscript will be submitted by the Investigator to the HPTN Manuscript Review Committee (MRC), 
DAIDS, and ViiV Healthcare for review prior to submission.

FOOTNOTES FOR APPENDIX I: 
1 Staff are required to observe participants take one pill at Enrollment.  If participants return with their pills at Weeks 2 & 4, staff will 
observe participant take one pill then as well, unless the participant has already taken oral study product that day. Participants must not 
be asked to take a second dose of oral study product for the sake of observation. 
2  Full physical exam is to be conducted during Enrollment.  A targeted physical exam will be done at all other visits. Participant pulse, 
blood pressure and weight must be recorded at every visit.  BMI must be calculated. 
3 The initial dose of the Hep B vaccination will ideally be given at Week 2, though there is flexibility around the timing of the 
vaccination. Subsequent doses may be given at different visits than indicated in this SOE, as long as sites follow manufacturer 
guideline timing. 
4 The HIV testing algorithm is provided in the SSP Manual. Testing for acute HIV must be negative and must be performed within 14 
days prior to enrolling the participant. If HIV rapid testing is indicated, this testing may be performed in the clinic or the laboratory.  At 
least one HIV test must be available and reviewed the same day as sample collection and before product is administered.  
5 Pregnancy testing may be performed in the clinic or the laboratory. Results must be available the same day as sample collection and 
before product is administered. Testing may be performed using a urine, plasma, or serum sample. The assay used for pregnancy 
testing must have a limit of detection of 25 mIU/mL or lower. Confirmation of pregnancy at a subsequent visit at least 4 weeks after the 
initial pregnancy test is required. Participants with confirmed pregnancies will permanently discontinue oral CAB and will not 
transition to Step 2. They will skip to Step 3, be provided open label TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) as PrEP and be reviewed every 12 weeks until delivery. If pregnancy is not confirmed on subsequent testing, Step 1 
participants will exit the study. Site staff will refer to their SOP for detailed management.

6 Participants will be tested for Hepatitis B surface antibody (HBsAb), and Hepatitis B core antibody (HBcAb, total) at Screening or 
Enrollment. HbsAg and HCV Ab must be resulted and reviewed prior to enrollment. 
7 At Screening: Creatinine. At and after enrollment: BUN/urea, creatinine, CPK, calcium, phosphorous, glucose, amylase, and lipase. 
8 At Screening: ALT and TBili. At and after Enrollment: AST, ALT, total bilirubin, and alkaline phosphatase.  
9 Total cholesterol, HDL, triglycerides, and LDL (either calculated or measured). Participants must have fasted for at least 8 hours, 
preferably 12 hours, prior to sample collection. Do not collect or test if <8 hrs fasting.  
10 Stored plasma will be used for Quality Assurance testing and other assessments at the HPTN LC (see Section 9). Assessments will 
be performed retrospectively; results will not be returned to study sites or participants, except as noted in SSP. Samples cannot be used 
by site or other lab for local purposes without specific instructions from the LC w/CMC consult.

APPENDIX IV: SCHEDULE OF ADDITIONAL PROCEDURES FOR 
REACTIVE/POSITIVE HIV TESTS  
(For enrolled participants) 
 
• Note 1:  The procedures listed for the HIV Confirmation Visit apply to participants who 
acquire HIV infection at any time during the study.  They are completed in addition to the 
procedures included in Appendix II. The procedures listed for Weeks 12, 24, 36, and 48 
apply to participants who acquire HIV infection after having one or more injections.  
Participants who acquire HIV in Step 3 may undergo similar procedures as listed in 
Weeks 12, 24, 26, and 48, and will be determined by the members of protocol team. Note 
that participants who acquire HIV-infection during Step 1 will permanently discontinue 
study product, will be terminated from the study, and be referred for HIV-related care.   
 
FOOTNOTES FOR APPENDIX IV: 
1 The HIV confirmatory visit must be held on a different day from the visit where the participant had their initial 
reactive/positive HIV test.  The testing algorithm for the HIV Confirmation Visit is provided in the SSP Manual. If HIV rapid 
testing is included in the HIV testing algorithm, this testing may be performed in the clinic or the laboratory.     
2 Sites will collect specimens for resistance testing at a local laboratory to assist with clinical management; results from 
resistance testing performed at local laboratories will not be reported to the SDMC.  Stored plasma may not be used real-
time/local resistance testing; additional samples must be collected for this testing.

APPENDIX VI: TOXICITY MANAGEMENT 
Toxicity Management General Guidance 
In general, the IoR has the discretion to hold study product at any time if she/he feels that continued 
product use would be harmful to the participant or interfere with treatment deemed clinically necessary 
according to the judgment of the IoR. In addition, a CMC has been established for this study. The 
CMC’s responsibilities will include consultation and decision-making regarding management of 
toxicities and study product administration, including product resumption following the occurrence of 
certain types of toxicities and/or permanent discontinuation. Throughout this appendix are examples of 
AEs that require consultation with the CMC; in all such cases, the CMC should be notified as soon as 
possible and ideally within 72 hours of site awareness of the AE in question. IoRs also should consult 
the CMC for further guidance in restarting study product or progressing to permanent discontinuation.  
The following general guidance refers to all AEs except for ALT. Refer to the table below for specific 
guidance for ALT. 
Grade 1 or 2 
In general, participants who develop a Grade 1 or 2 AE regardless of relatedness to study product, and 
that is not specifically addressed elsewhere in the protocol or in the Tables below may continue use of 
the study product per protocol.             
Grade 3 
For participants who develop a Grade 3 AE or toxicity that is not specifically addressed elsewhere in the 
protocol or in the Tables below and is judged to be related to study product by the IoR, study product 
use should be temporarily discontinued in consultation with the CMC. In general, and unless otherwise 
decided in consultation with the CMC, the IoR should re-evaluate the participant until resolution of the 
toxicity.  
 
Related: 
For Grade 3 AEs deemed related to study product, the study product should be 
permanently discontinued if improvement to severity ≤ Grade 2 cannot be documented 
within 4 weeks of receipt of the initial result. If study product is resumed and the same 
Grade 3 AE recurs at any time, the IoR must consult the CMC for further guidance on 
holding of study product, frequency of reevaluation or progression to permanent 
discontinuation of the study product.   
 
Unrelated: 
For Grade 3 AEs deemed unrelated to study product, the CMC should be consulted for 
further management recommendations.  
Grade 4 
Participants who develop a Grade 4 AE or toxicity that is not specifically addressed elsewhere in the 
protocol or in the Tables below (regardless of relationship to study product) must have the study product 
temporarily discontinued. The IoR must consult the CMC and continue the temporary study product 
hold until a recommendation is obtained from the CMC.  
 

 
HPTN 084-01, FINAL Version 1.0 
 
80 of 117 
14 October 2019 
In general, study product use will not be resumed if the Grade 4 AE is considered related to study 
product use. If, in consultation with the CMC, study product use is resumed and the same Grade 4 AE 
recurs at Grade 4 level at any time, study product must then be permanently discontinued. 
General Criteria for Discontinuation of Study Product 
Participants may voluntarily discontinue the study product for any reason at any time. IoRs will 
permanently discontinue participants from study product per protocol for any of the specific criteria 
below, which may be further clarified in the SSP Manual. IoRs also may permanently discontinue 
participants for reasons not shown here or in the SSP Manual (e.g., to protect participants’ safety and/or 
if participants are unable or unwilling to comply with study product use procedures). In such cases, the 
IoR or designee must first query the CMC for review. The CMC will provide a written response to the 
site indicating whether the CMC has recommended permanent discontinuation of study product based 
on careful review of all relevant data. It should be noted that the safety of the participant should always 
take precedence, and therefore, an IoR may determine that study product be permanently discontinued 
before the CMC has time to respond. This is acceptable, and in such cases, the CMC should be notified 
as soon as possible regarding the nature of the case and the course of action taken.   
The criteria for permanent discontinuation of study product use for an individual participant are: 
• Study product-related toxicity requiring permanent discontinuation of study product per 
the guidelines above and below 
• Completion of regimen as defined in the protocol 
• Request by participant to terminate study product 
• Clinical reasons determined by the IoR  
• Acquires HIV infection or HBV infection   
Study product will be temporarily withheld from a participant for any of the following reasons: 
• Report of use of prohibited concomitant medications as described in Protocol Section 4.4.  
Study product use may resume upon consultation with the CMC and when the participant 
reports that she is no longer taking the prohibited medication, provided other reasons for 
temporary study product hold/permanent discontinuation do not apply. The CMC should 
be consulted in all cases where a participant reports taking a prohibited product during 
the course of the study.   
• The participant is unable or unwilling to comply with required study procedures such as 
HIV testing and routine laboratory assessments, or otherwise might be put at undue risk 
to their safety and well-being by continuing study product use, according to the judgment 
of the IoR. The IoR must consult the CMC on all temporary study product holds 
instituted for this reason for further guidance on resuming study product use, continuing 
the temporary hold, or progressing to permanent discontinuation.   
• The participant has one or more reactive HIV test results, or expresses a concern about 
having acute HIV infection. Criteria for resuming use of study product in these 
circumstances are defined in the protocol and SSP Manual.

Oral Phase: 
Participants who temporarily or permanently discontinue study product during the Step 1, Oral Run-in 
Phase, will be instructed to return all study products as soon as possible. 
Injection Phase: 
Participants who have received at least one injection and refuse further injections or discontinue due to 
an AE will be transitioned to quarterly follow-up.

GUIDANCE ON TOXICITY MANAGEMENT FOR SPECIFIED TOXICITIES: 
ALT 
Note for all Grades:  
All study participants will be negative for HBsAg at study entry, and participants who enter the study 
without evidence of immunity to HBV will be provided HBV vaccination. Therefore, pre-existing HBV 
infection is not likely to be a cause of AST/ALT elevations. 
Careful assessments should be done to rule out the use of alcohol, lactic acidosis syndrome, non-study 
medication-related product toxicity, herbal medications/supplements, or viral hepatitis as the cause of 
elevation in AST or ALT of any Grade. The participant must be carefully assessed for any symptoms or 
signs of hepatotoxicity, including fatigue, malaise, anorexia and nausea, jaundice, acholic stools, right 
upper quadrant pain, or hepatomegaly. If the AST/ALT elevation is considered most likely to be due to 
concomitant illness or medication, standard management, including discontinuation of the likely 
causative agent, if possible, should be undertaken. If symptoms or signs of clinical hepatitis are present, 
study product must be held or discontinued. In addition, all participants with elevated values should be 
considered for testing for hepatitis A, B, and C infection.   
Note the following for cases of exercise-induced CPK abnormalities:   
Note the following for cases of exercise-induced CPK abnormalities: Cases of CPK abnormality > 
Grade 3 or higher, presumed to be exercise induced, accompanied by < Grade 3 ALT must be brought to 
the attention of the CMC for adjudication of further management and further administration of study 
product. Grades 3 and 4 elevations in ALT, regardless of CK elevation will prompt permanent 
discontinuation of study product and the participant will be followed annually for HIV testing only until 
the conclusion of Step 2 of the study. All such cases must be reported to the CMC.

ELEVATIONS in ALT  
Grade 2 and higher 
Oral phase: A Grade 2 ALT abnormality reported at Week 2 or Week 4, 
regardless of relatedness to the study product, should be confirmed within 
one week. Oral study drug may continue until the confirmatory results are 
available; no injections should be administered until confirmatory results 
are available during consideration of the Week 4 ALT value. If the repeat 
value is < Grade 2 at Week 3, study drug may continue to Week 4. If the 
repeat value is < Grade 2 at Week 4, the participant may proceed to the 
injection phase. If the repeat value is Grade 2 or higher at Week 4, study 
product should be stopped, and the participant will be discontinued from the 
study. All such cases must be reported to the CMC. In addition, participants 
will be followed with weekly ALT assessments until they return to < Grade 
1.   
• A Grade 3 or higher ALT abnormality, regardless of relatedness 
to the study product, will result in permanent study product 
discontinuation and will prohibit a participant from entering the 
injection phase of the study, and the participant will be followed 
annually for HIV testing only until the conclusion of Step 2 of 
the study. All such cases must be reported to the CMC. In 
addition, participants will be followed with weekly ALT 
assessments until they return to < Grade 1.   
Grade 2 and higher 
• Injection phase: The CMC should be notified as soon as 
possible. For a Grade 2 ALT, the CMC will determine whether 
further injections may be given in cases where levels are ≤ 
Grade 2 prior to the next scheduled injection. Unless otherwise 
specified by the CMC, for Grade 2 ALT, repeat testing should 
be performed weekly until levels are ≤ Grade 1.  For Grade 3 
and higher ALT, study product will be permanently 
discontinued.* For Grade 3 and 4 ALT, repeat testing should be 
performed as soon as possible, and participants should be 
followed weekly until levels are ≤ Grade 1. Participants who are 
permanently discontinued from study product will be followed 
for 48 weeks post-last injection.

Continue study product 
until repeat test results are 
available 
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 products known 
to cause increase of CPK (such as statins) 
physical activity or exercise preceding the 
CPK evaluation should be obtained.  
Grade 4 
Continue study product 
until repeat test results are 
available if the elevation is 
thought to be possibly or 
probably related to study 
product. 
Grade 4 elevations in CPK should have a 
repeat assessment after the subject has 
abstained from exercise for >24 hours. 
For persistent Grade 4 CPK elevations 
that are considered possibly or probably 
related to the study product, study 
product should be discontinued and the 
participant should be followed on 
study/off study product.

GUIDANCE ON TOXICITY MANAGEMENT FOR SPECIFIED TOXICITIES: 
Guidance for Injection Site Reactions (ISRs) 
The CMC must be informed of all Grade 3 or 4 ISRs to determine etiology and assess appropriate 
continued study participation. 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.  
 
Guidance for Allergic Reactions 
Participants may continue to receive oral or injectable study product for Grade 1 or 2 allergic reactions 
at the discretion of the IoR or designee. The participant should be advised to contact the study site staff 
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 related to study product should 
permanently discontinue study product and continue to be followed quarterly. Participants should be 
treated as clinically appropriate and followed until resolution of the AE.

1. Why is this research being done? 
There is a new medication called cabotegravir (CAB) that can treat people who have HIV infection. 
CAB is also being tested to see if it can protect people from getting HIV. In this study, we want to 
know if it is safe and acceptable for adolescent girls who do not have HIV to take CAB. For more 
information, please see the What is this Study About section below.   
 
2. What will happen to me during the study? 
You will move through the study in 3 steps: 
• Step 1: You will take one CAB pill every day for five weeks 
• Step 2: You will receive a total of 5 CAB injections over 6 months 
• Step 3: You will come to the clinic for study visits quarterly for up to one year. 
 
Different procedures are done at different study visits. The procedures include: 
• Physical examinations – We will examine you to check on your health by measuring height, 
weight, temperature and blood pressure.  
• Questions – We will ask general questions about your age, living situation, medical health, 
and as well as beliefs about HIV, opinions about taking pills and getting injections, sexual 
behavior, and any alcohol or drug use. 
• Counselling – We will discuss ways to protect you from getting HIV and offer condoms. We 
will discuss any challenges you have taking the CAB pill or attending study visits. 
• Contraception and Pregnancy – Even if you are not currently sexually active, you must agree 
to use a long-acting, reversible type of contraception. We will provide you with 
contraception and related counselling throughout this study and test you for pregnancy. 
• CAB pills or injection – During Step 1, we will explain how to take the study pills, watch you 
take a study pill, and explain any side effects the pills may cause. In Step 2, the CAB 
injection will be given into your buttock.  
• Laboratory tests – We will collect blood, urine and vaginal swabs to test for HIV, Hepatitis, 
liver and kidney health, cholesterol, and sexually transmitted infections. 
• HIV Prevention – We will offer you Truvada tablets as PrEP after you stops the CAB 
injections.  
 
For more information on each procedure and when it happens, please see the What Will I have to Do 
in the Study section below.   
 
3. How long will I participate in the study? 
If you decide to join the study, participation will last about 1.5 years and include a maximum of 18 
study visits at this clinic. 
 
4. Will I benefit from the study? 
It is possible that you may benefit from taking part in this study; however, there is no guarantee that 
it will help you. You will get information about your health and the results of the tests, as well as 
treatment for sexually transmitted infections. The counseling you get during this study may help you 
avoid HIV and other sexually transmitted infections. For more information, please see What are the 
Potential Benefits of Taking Part in the Study section below.

INTRODUCTION 
We invite you to take part in a research study about PrEP for Human Immunodeficiency Virus (HIV). 
PrEP is short for Pre-Exposure Prophylaxis. Pre-exposure means before being exposed to HIV. 
Prophylaxis is the way people prevent a disease from infecting them. With PrEP for HIV, medications 
are being developed to prevent people from getting infected if they are exposed to HIV.  
 
This form gives information about what it means to join the study. Please read it, or have it read to you, 
and ask any questions that you may have. You can take as much time as you need to fully understand the 
study. We will ask questions to see if we have explained the study clearly. After you understand the 
study, if you decide that you will take part, we will ask you to sign or make your mark on this form. You 
will be offered a copy to keep. Because you are still a minor, we must have permission from a parent or 
guardian for you to take part. This process is called “informed consent.” 
 
WHAT IS THIS STUDY ABOUT? 
In this study, we want to know if it is safe and acceptable for adolescent women who do not have HIV to 
take an anti-HIV drug called cabotegravir (CAB). We would also like to look at the tolerability, or side 
effects, of CAB. CAB is a new medicine that is still being studied. Other studies showed that CABcan 
treat people who have HIV infection, but we do not know if CAB could also be used as PrEP to protect 
people from getting HIV. First, we must study if CAB is safe for people who do not have HIV. CAB 
comes in the form of a pill and also as an injection [sites may insert appropriate term commonly used 
e.g. (shot)]. CAB pills and injections are not yet approved for the treatment or prevention of HIV 
infection by the US FDA or [add local drug regulatory authority]. CAB injections are not HIV 
vaccinations. 
 
You are being invited to join this study because you live in sub-Saharan Africa, where young women are 
at high risk of getting infected with HIV – as many as five to ten out of 100 each year. This study will be 

 
HPTN 084-01, FINAL Version 1.0 
 
92 of 117

offered to about 50 women under 18 years old across several study sites in Africa. The person in charge 
of the study at [insert site name] is [insert name of IoR]. The United States National Institutes of Health 
is paying for the study. 
 
Some of the questions that we want to answer with this study are: 
• Is it safe for adolescent women to take CAB pills and CAB injections? 
• Is it acceptable and practical for adolescent women to use CAB for HIV prevention? 
• Are adolescent women able to make it to the clinic for injection appointments? 
• What do parents/guardians think about their daughters using CAB for HIV prevention? 
 
This study will not show us if CAB prevents new infections with HIV. There are other studies being 
done that will answer that question, but those studies only involve adults. Currently, the only known 
way to prevent HIV infection from sex is to use condoms and/or take the PrEP pill called 
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) every day. But, some 
people have a hard time remembering to take a pill every day, so it is a good idea to have other HIV 
prevention options. If the CAB injections work, people could get injections every 8 weeks and would 
not have to remember to take a pill every day. It is important that we learn what happens when 
adolescent women use CAB for HIV prevention and whether it is safe and acceptable. 
 
A description of this study will be available on www.ClinicalTrials.gov. This website will not include 
information that can identify you. At most the website will include a summary of the results. You can 
search this website at any time. 
 
DO I HAVE TO JOIN THIS STUDY? 
You do not have to be in this study. The study staff can tell you about other places where you can get the 
care you need even if you do not join the study. If you join the study today, you can still change your 
mind later and leave the study at any time for any reason without penalty. If you decide not to take part 
in this study, you can join another study at a later time if one is available and you qualify for it. 
 
You can’t join this study if you are taking part in another study of drugs, HIV vaccines, or medical 
devices. You must tell the study staff about any other studies you are taking part in or thinking of taking 
part in. This is very important for your safety. [Some sites may have biometric fingerprint screening 
and, if so, sites should add information regarding that here.] 
 
HOW LONG WILL THE STUDY LAST? 
If you decide to join the study, participation will last about 1.5 years and include about18 study visits at 
this clinic. You will move through the study in 3 steps: 
 
• Step 1: You will take one CAB pill every day for five weeks 
• Step 2: You will receive a total of 5 CAB injections over 6 months 
• Step 3: You will come to the clinic for study visits quarterly for up to one year

If you want to be in this study, you will sign this consent form before you begin the study.  
 
Study Visit Schedule 
• Screening (1 visit) – First, we will find out if you qualify to be in the study.  
• Step 1 (3 visits) – If you qualify and decide to join the study, you will swallow 1 CAB tablet 
every day for 5 weeks starting at the Entry, or Enrollment, Visit. Step 1 is done to make sure 
your body is tolerating the CAB well, so you should take the tablets every day.  You will come 
back for a medical check-up at weeks 2 and 4. If Step 1 goes well for you, then you will move to 
Step 2. 
• Step 2 (10 visits) – If you qualify, you will get the first CAB injection at week 5, then again at 
weeks 9, 17, 25 and 33 (5 injection visits). You will come back to the study clinic for a brief 
check-up 1 week after each injection at weeks 6, 10, 18, 26 and 34 (5 safety visits). You will also 
come back to the study clinic for a blood draw 8 weeks after the last injection.  
• Step 3 (5 visits) – After a blood draw 8 weeks after your last injection, you will come to the 
clinic quarterly (every 3 months) for almost a year to check how you are doing and to see how 
long CAB remains in your body after your last injection (+8, +12, +24, +36, +48 weeks). In most 
people, CAB disappears from the body slowly over 6 months, but it may last for a year or so. 
During this Step, you will be provided with TENOFOVIR/EMTRICITABINE (TRADE NAME: 
TDF/FTC, TRUVADA®) to take daily, so we will be following you to see how well things are 
going on oral PrEP and doing bloodwork, as well as HIV and other STI testing. 
 
You will be in the study for about 1.5 years. Your parent/guardian does not need to come with you to the 
study visits. The study visits will take from 1 to 4 hours each [sites to modify accordingly]. It is 
important that you attend all of these study visits. If you do not come for a scheduled visit or if a test 
result comes back abnormal, study staff will contact you or visit you. We will ask for your address and 
contact information so that we will be able to get in touch with you. You should not join the study if it’s 
not okay for study staff to contact you and visit you where you stay. If at any time you feel sick, you 
should let the study staff know right away and we may ask you to come back for a check-up.  
 
Study Visit Procedures 
 
Different procedures are done at different study visits. We will now explain each of the procedures and 
then show you which ones are done at which visits.  
 
• Physical examinations – We will examine you to check on your health by measuring height, 
weight, temperature and blood pressure. At each study visit, we will check on whether CAB may 
be causing side effects. We will also tell you what to do if you have side effects. 
• Questions – We will ask general questions about your age, living situation, medical health, and 
any medications or vitamins that you takes. At some visits, you will also answer questions on a 
computer about your beliefs about HIV, opinions about taking pills and getting injections, sexual 
behavior, and any alcohol or drug use (we call these questions “CASI” for computer-assisted 
self-interview). 

 
HPTN 084-01, FINAL Version 1.0 
 
94 of 117 
14 October 2019 
• Counselling – We will discuss ways to protect you from getting HIV and offer condoms. We will 
talk to you about plans in the next year for becoming pregnant. We will discuss any challenges 
you have about taking the CAB pill or attending study visits. 
• Contraception and pregnancy – We will provide you with contraception throughout this study 
free of charge because we do not know if CAB will harm a baby. Even if you are not currently 
sexually active, you must agree to use a long-acting, reversible type of contraception. These 
include implants, injectables, and intrauterine devices (IUD). You must agree to use one of these 
forms of contraception during the study and for 48 weeks (almost a year) after stopping CAB 
injections because CAB remains in the body for a long time. If you leave the study early (in Step 
1), you must agree to use contraception for 30 days after stopping oral study product. Study staff 
will discuss with you and help choose a method of contraception that will work best for you. At 
the majority of visits, we will check your contraception, test you for pregnancy (urine test) [site 
insert sample type] and offer you condoms. 
• 
CAB pills or injection – During Step 1, we will explain how to take the study pills, watch you 
take a study pill, and explain any side effects the pills may cause. In Step 2, the CAB injection 
will be given into your buttock.  
 
• Laboratory tests – We will collect blood, urine and a vaginal swab. Some of these tests are done 
right away and we will tell you the results when they are available. The HIV results will be 
available before you are given CAB each time. Other tests are stored and then done later in a 
batch. More details are shown in the table below this section. Some tests are done in laboratories 
in another country, so your samples may be shipped there for testing. The laboratory tests are 
done for the following reasons: 
 
o Blood – To check for infections (HIV, hepatitis B and C, Syphilis), your general health, 
the health of the liver and kidneys, the amount of cholesterol (a fatty substance in your 
blood) and the amount of the study drug that is in your blood. How much blood is taken 
depends on which tests are due at each visit and is between 1 and 4 teaspoons each time 
(5-20mL). Study staff will tell you more about fasting before the cholesterol test. 
o Urine – To test if there is sugar or protein in your urine and for sexually transmitted 
infections and pregnancy. [Sites to distinguish if prenancy testing is done via urine or 
plasma/serum.] 
o Vaginal swab – To test for sexually transmitted infections. 
 
• Hepatitis B vaccination – At Week 2 or soon thereafter, you will be given the hepatitis B 
vaccination if testing shows you are not already immune. Additional vaccination (boosters) will 
be given at approximately Weeks 6 and 33.  
• HIV Prevention – We do not know for sure if CAB will protect you from getting HIV. Also, the 
amount of CAB remaining in the body disappears slowly after you stops the CAB injections – it 
can last in the body for about one year, so you must use other ways of preventing HIV if you are 
at risk of infection. For this reason, we will offer you TENOFOVIR/EMTRICITABINE

(TRADE NAME: TDF/FTC, TRUVADA®) tablets as PrEP after you stop the CAB injections. 
Before you leave the study, we will help you find a place where you can continue getting HIV 
prevention care [sites to add information here or elsewhere in the consent form].

Permanently Stopping Study Medicine 
 
CAB pills are only given in Step 1, and then stopped permanently. If you need to leave the study before 
you receive any CAB injections, we’d still like to do a final study visit, which will include the same 
activities as the Step 3 Follow-Up Visits. If you permanently stop taking CAB after you had at least 1 
CAB injection, then you will move straight to Step 3 follow-up visits, if you agree to stay in the study. 
 
WHAT IF I BECOME INFECTED WITH HIV? 
Being in this study will not cause HIV infection, but you could become infected with HIV through sex 
or other activities while in this study. If you get HIV infection, you will stop using CAB, but you should 
still come for the study visits to make sure that you are doing okay. The study staff will counsel you and 
refer you for HIV treatment and other available services, but the study will not pay for this treatment. 
We will share any test results that will help you get the treatment you need. Testing, which will take an 
additional 1-3 mL of blood, will be done to see if your HIV is resistant to any drugs that are used to treat 
HIV infection. This testing will help select the best drugs to treat your HIV infection. 
 
Tables of Study Visit Procedures if you become infected with HIV during Step 2 or Step 3 
If you become infected with HIV infection before your first injection, you will have the oral CAB 
stopped permanently and will be referred to local HIV-related care and exit from the study. 
 
WHAT IF I BECOME PREGNANT? 
You should not fall pregnant while receiving CAB. During the study you will use contraception. If there 
is a reason you can’t use contraception or if you wish to be pregnant in the next two years, you should 
not join the study. The reason for this is because the World Health Organization recommends that 
women should not fall pregnant when using a medicine similar to CAB, called Dolutegravir, until more 
information is available about using these drugs during pregnancy. If you become pregnant during this 
study, you will stop CAB injections and we will refer you to available maternity care. CAB will 
probably last in your body and the baby’s body throughout the pregnancy up until delivery. If you are 
still pregnant after your last study visit, we will ask your doctor to provide updates on the progress of the 
pregnancy. The outcome of the pregnancy is important to the study, so we would like updates for the 
first year of your baby’s life. The study doctor will share this information with the study sponsor for 
safety monitoring follow-up.

o You will permanently discontinue oral CAB and will not transition to Step 2. You will skip 
to Step 3, be provided TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) tablets as PrEP, and visit us every 12 weeks until delivery. If your pregnancy 
is not confirmed on subsequent testing, you will exit the study.  
• If you become pregnant in Steps 2 and 3: 
o If you become pregnant in Step 2, you will permanently discontinue CAB LA injections and 
transition to Step 3 to be followed by the study every 12 weeks for 48 weeks after the last 
CAB LA injection or delivery, whichever comes last. You will be provided with 
TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) tablets as 
PrEP  for 48 weeks after the last CAB injection.  
 
WHAT OTHER TESTS WILL BE DONE? 
After all the laboratory tests mentioned above for this study have been done, there may be some of your 
samples left over. We want to keep these in storage for future tests related to HIV and other infections, 
including testing for the medications used in this study and other anti-HIV medications, or tests about 
your genes. There is a separate informed consent form with more information about this. We will not 
use DNA from your stored samples to study your whole genetic sequence (also called your "genome"). 
 
WHAT ARE THE RISKS OF TAKING PART IN THIS STUDY? 
Taking part in this study may involve some risks and discomfort. 
 
• Risk from Blood Draws – The needle can cause pain, swelling, bruising, or bleeding from the 
needle site. Drawing blood can cause fainting or infection, but this is very rare. 
 
• Risk from Receiving CAB Injections – People who got CAB injections in other studies had pain, 
skin irritation, skin redness, bumps, swelling, itching, or bruising at the spot where they got the 
shot. Most reactions go away in a week or less but sometimes they can last a long time. The 
injection could be given too deeply or not deeply enough, missing the muscle and entering your 
skin, blood, or a nerve. Everything possible will be done to decrease this risk, including watching 
you for problems during the study. If we think that the injection was not given the right way, you 
might be asked to stay in the clinic up to 2 hours [sites to modify] after the injection to watch 
how you are doing. Receiving injections can cause some people to feel lightheaded or feel like 
they might pass out, or 'faint'.  This is called a 'vasovagal reaction' and it can occur with many 
medical procedures but usually resolves quickly. 
 
• Risk of CAB Side Effects – All medications can cause side effects. Some side effects are minor; 
others can be severe. Some side effects are common; others are rare. Some people who take 
medication have some of the side effects. Other people have different side effects, or no side 
effects. The most common side effects for CAB are listed below. It is not known if CAB, other 
drugs or the patient’s other health problems caused these side effects. There may be other side 
effects that we do not know about now. This may be especially true for adolescents, because this 
is the first study of CAB in adolescents.

Very Common Side Effects of CAB 
Common Side Effects of CAB 
• Nausea (feeling sick to the stomach) 
• Diarrhea or loose stools 
• Runny nose, sore throat/Upper respiratory tract 
infection 
• Headache 
• Fever 
• Lack of energy 
 
• Rash 
• Itching  
• Vomiting (being sick) 
• Stomach pain and discomfort  
• Problems sleeping  
• Abnormal dreams/nightmares 
• Feeling light headed 
• Depression 
• Passing gas or wind 
• Joint or muscle pain 
• Increase in the level of enzymes made in the muscles 
(creatine phosphokinase) 
 
Some of the people who received CAB in other studies also had abnormal liver tests. In most 
people, this was explained by other things such as a new virus infection with Hepatitis. Very few 
people did not have another possible reason, so it is possible that a mild form of liver damage 
happened from taking CAB.  In those people, the liver tests got better after stopping CAB, 
showing that any damage was temporary. Seizures have been seen (rarely) in people who had 
CAB. They are not thought to be caused by CAB, but the study staff will ask you about them. 
We have an information sheet about CAB and its side effects for you to keep. 
 
• Risk of HIV Resistance to CAB – We do not know if using CAB for PrEP will mean that CAB 
will not work to treat the HIV  if you get infected with HIV during the study or in the future (this 
is called drug resistance). Drug resistance usually occurs when the amount of a medicine in the 
body is too low to kill the virus. You will have low levels of CAB in the body for about one year 
after the last injection, or if you don’t  get the injections when they are due. This is why it is very 
important that you use other methods to protect against HIV infection whenever you are  at risk, 
like using condoms and TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) PrEP pills.   
 
• Risks potentially related to TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) for PrEP - Like all other medicines, you may have symptoms or side effects 
while taking PrEP. These symptoms or sides effects may be due to participation in the study or 
due to illnesses that have no relation to the study, like a cold or flu. You should tell the staff at 
the study clinic about any symptoms that you feel while you are participating in the study. In past 
PrEP research studies, nausea and diarrhea were the most common side effects, but happened in 
only about 10% or 1 in 10 people. Nausea and diarrhea mainly happened in the first month and 
then went away. A small number (<1% or 1 out of 100 people) in PrEP studies showed a small 
decrease in how their kidneys work, but this stopped when the people stopped taking the drug. 
Other side effects were very rare and have always gotten better when the drug was stopped.  
 
• Risks of Asking Sensitive Questions – You may feel uncomfortable when we ask personal 
questions. You do not have to answer any question that you do not want to and you can stop 
answering the questions at any time.

• 
Risk of Disclosure of Private Information – We will make every effort to keep your information 
private and confidential. It is possible that others may learn that you are part of this study and 
they may think that you are infected with HIV or are at high risk for HIV. Because of this you 
may feel stigma, stress or embarrassment. We will not share any information about you or your 
health with anyone, even your parent/guardian, without talking to you first, except when [sites to 
insert relevant information about any legal obligations for disclosure, for example…your life is thought 
to be in danger 
 
• Other Risks – There may be uncommon or previously unknown risks that might occur. You 
should report any problems to the researchers immediately. 
 
WHAT ARE THE BENEFITS OF TAKING PART IN THIS STUDY? 
You may not get direct benefit from being in this study. You will get information about your health and 
the results of the tests, as well as treatment for sexually transmitted infections and free contraception. 
The counseling you get during this study may help you avoid HIV and other sexually transmitted 
infections. You or others in your community may benefit from this study later. The information gathered 
during this study may help to prevent the spread of HIV. This may be beneficial to you and your 
community.   
 
ARE THERE ANY COSTS TO ME FOR TAKING PART IN THIS STUDY? 
You will pay no money to be in the study.    
 
WHAT OTHER CHOICES DO I HAVE? 
It is possible that TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, TRUVADA®) PrEP 
is available in your local area for HIV prevention. Because we do not know if CAB injections will 
protect you against HIV, if you prefer to take PrEP instead of joining the study, ask the clinic staff to 
refer you for HIV prevention medical services.  
 
Sites to include/amend the following if applicable: There may be other studies going on here or in the 
community that you may be eligible for. If you wish, we will tell you about other studies that we know 
about. There also may be other places where you can go for HIV counseling and testing. We will tell you 
about those places if you wish.] 
 
WILL I BE TOLD IF THERE IS NEW INFORMATION? 
You will be told about any new information learned during the course of the study that might cause you 
to change your mind about being in the study. At the end of the study, you will be told when study 
results may be available and how we will let you know about the results. 
 
ARE THERE ANY REASONS WHY I MAY BE ASKED TO STOP TAKING PART IN THIS 
STUDY? 
You may be withdrawn from the study if any of the following occur:  
• You are unable or unwilling to attend clinic visits and/or follow all of the study procedures or 
instructions.   
• You could be harmed by continuing to take the pills or getting an injection. 
• The study is stopped or canceled. 
• The study staff feels that staying in the study would be harmful to you. 
• Other reasons, as decided by the study staff.

WHAT WILL I GET FOR TAKING PART IN THIS STUDY? 
You will receive [sites to fill in] for your time, effort, and travel to and from the clinic at each scheduled 
visit.  
 
HOW WILL MY PRIVACY BE PROTECTED? 
To keep your information private, your samples will be labeled with a code that can only be traced 
back to the study clinic. Your name, where you live, and other personal information will be 
protected by the study clinic. The results of any tests done will not be included in your health 
records without your permission. Every effort will be made to keep your personal information 
confidential, but we cannot guarantee absolute confidentiality. Your records may be reviewed, under 
guidelines of the United States Federal Privacy Act, by the United States Food and Drug Administration 
(FDA); the sponsor of the study (United States National Institutes of Health [NIH]), other US, local and 
international regulatory entities may also review your study records, as well as the [insert name of site 
here] Institutional Review Board (IRB), Ethics Committee (EC), study staff, study monitors, the 
company that makes CAB, and [insert applicable local authorities]. 
 
Groups that oversee the study include:  
• 
[insert name of site IRB/EC] 
• 
[insert name of site drug regulatory authority] 
• 
[insert name of other site regulatory entities] 
• 
Representatives of the HPTN 
•

• 
The United States Food and Drug Administration 
• 
The United States Office for Human Research Protections 
• 
Other U.S., local, and international regulatory entities 
• 
ViiV Healthcare (the company that makes CAB) 
 
The study staff and these groups are required to keep study records private and confidential. The results 
of the study may be presented publicly or published.  However, no presentation or publication will use 
your name or identify you personally. Your study information may be given to other authorities if 
required by law, including diagnoses of sexually transmitted infections. [Sites add more specific detail 
here as needed; example follows:] For example, we are required to follow state laws and report any risk 
of harm to you or others. This would include sexual activity with an adult while you are a minor. 
 
In addition to the efforts made by the study staff to help keep your personal information confidential, we 
have obtained a Certificate of Confidentiality from the U.S. Federal Government. This Certificate 
protects researchers from being forced to tell people who are not connected with this study your 
participation. The Certificate of Confidentiality does not prevent you from releasing information about 
yourself and your participation in the study. The Certificate cannot be used to resist a demand for 
information from personnel of the United States Government that is used for auditing or evaluation of 
federally funded projects or for information that must be disclosed in order to meet the requirements of 

 
HPTN 084-01, FINAL Version 1.0

14 October 2019 
the federal Food and Drug Administration (FDA). Even with the Certificate of Confidentiality, if the 
study staff learns of possible child abuse and/or neglect or a risk of harm to you or others, we will tell 
the proper authorities. 
 
WHAT HAPPENS IF I AM INJURED DURING THE STUDY? 
Your health is important to us.  We will make every effort to protect your well-being and minimize 
risks.  It is possible, however, that you could have an illness or injury that is study-related.  This means 
that the illness or injury occurred as a direct result of the study procedures or the study drug.  
 
[Sites may modify this paragraph to reflect local institutional policies; information regarding coverage 
available through clinical trial insurance obtained by the site should be included if applicable; the 
statement regarding no program for compensation through the NIH may not be removed.]  If a study-
RELATED illness or injury occurs, we will treat you or tell you where you can get treatment.  The cost 
for this treatment may be charged to you or your insurance company.  There is no program for 
compensation either through [site name or] the U.S. National Institutes of Health. 
 
WHO DO I CONTACT IF I HAVE PROBLEMS OR QUESTIONS ABOUT THE STUDY? 
If you ever have any questions about the study, or if you have a research-related injury, you should 
contact [insert name of the investigator or other study staff] at [insert telephone number and/or physical 
address]. 
 
If you have questions about your rights as a research participant, you should contact [insert name or title 
of person on the IRB or other organization appropriate for the site] at [insert physical address and

INTRODUCTION 
You have decided to let your child join the study named above. As part of the study, she will have 
blood, urine and vaginal swabs collected. After all the tests for this study have been done for her, there 
may be some of the samples left over. We call these left over samples. The HPTN would like to keep 
these left over samples and use them for other research in the future. This form gives information about 
use of left over samples. Please read it, or have it read to you, and ask any questions you may have. 
After we discuss the information with you, you will record your decisions on use of extra samples at the 
end of the form.  
 
1. It is your decision whether or not to allow the left over samples to be used.  
You are free to say yes or no, and to change your mind at any time. Your decision will not affect her 
participation in the study. If you say no, all left over samples will be destroyed.  
 
2. If you agree, her leftover samples will be kept in a repository.  
[Sites should insert one of the two options shown below. Choose/adapt the second option if local 
regulations do not permit storage of samples for future research use in the United States.] 
 
A repository is a secure facility that is used to store samples. The HPTN repository is in the United 
States. If you agree to have left over samples stored, the samples will be kept in this repository. There is 
no limit on how long the samples will be kept [sites may insert time limits or additional site-specific 
requirements here if required by local authorities]. 
 
A repository is a secure facility that is used to store samples. The HPTN has a repository in the United 
States. However, our local regulations require that left over samples be stored in our country. Therefore, 
we will keep the samples here at our laboratory. There is no limit on how long the samples will be kept 

 
HPTN 084-01, FINAL Version 1.0 
 
104 of 117 
14 October 2019 
[sites may insert time limits or additional site-specific requirements here if required by local 
authorities]. 
 
3. Left over samples could be used for different types of research.  
Left over samples may be used for research on HIV and other infections, including testing for the 
medicines used in this study and other anti-HIV medicines, the immune system, and other diseases. The 
research may be done in the United States or in other locations. If you agree, the left over samples could 
also be used for research that looks at your child’s genes. Genes are passed to children from their birth 
parents. They affect how people look and how their bodies work. Differences in people’s genes can help 
explain why some people get a disease while others do not. Your child’s samples would only be used to 
look at genes related to how the body responds to the medicines used in this study and the immune 
system. These tests would not include whole genome sequencing (WGS). 
 
Any research done with the left over samples must be reviewed and approved by the HPTN. The 
research must also be approved by an ethics committee. The role of an ethics committee is to review the 
research plan and protect the rights and well-being of the people whose samples will be used.  
 
The research done with left over samples is not expected to give any information relevant to your child’s 
health. Therefore, the results will not be given to the study staff or to you. The results also will not be 
placed in your child’s study records. 
 
4. There is little risk to your child.  
When left over samples are used for research, they are labeled with a code number only. To protect your 
child’s privacy, no names are used. However, information such as age, gender, HIV status, and other 
health information may be linked to the samples. There may be some risks from tests of your child’s 
genes. If others found out the results of these tests, they could treat your child badly or unfairly. 
However, this is almost impossible because the results will not be given to the study staff or to you, and 
will not be in her study records. 
 
Any identifiers will be removed from the identifiable private information or biospecimens and, after 
removal, the information or biospecimens can be used for future research studies or distributed to 
another investigator for future research studies without additional informed consent. 
 
5. There may be no benefit to you or your child.  
By allowing your child’s left over samples to be used for research, she will be part of the search for new 
information that may benefit people in the future. However, the research done with the extra samples is 
not expected to directly benefit your child in any way.  
 
6. You will not be paid for use of your child’s samples. 
There is no cost to you for use of your child’s left over samples. The samples will not be sold, and you 
will not be paid for use of the samples. It is possible that research done with the samples could lead to a 
new discovery or a new product. If this happens, there is no plan to share any money with you or your 
child.  
 
7. Information from research using extra samples may be reviewed by groups that oversee the 
research. 
These groups include:

INTRODUCTION 
You are being asked to take part in a sub-study of the HPTN 084-1 research study that involves 
completing an interview. Joining this sub-study is voluntary. You may refuse to join, or you may 
withdraw your consent to be in this sub-study for any reason. Before you decide whether to join this 
sub-study we would like to explain the purpose of the interview, the risks and benefits to you and what 
is expected of you.  
  
This consent form gives information about being in the sub-study. We will help you to understand the 
form and answer your questions before you sign this form. Once you understand the sub-study, and if 
you agree to take part, you will be asked to sign your name or make your mark on this form. You will be 
offered a copy of this form to keep. Because you are a child, your parent/guardian must also give their 
permission.  
 
Note for parent/guardian – In this form, we use ‘you’ to refer to your child. 
 
Participation is voluntary 
Before you learn about the sub-study, it is important that you know the following: 
Your participation is voluntary. You do not have to take part in this sub-study if you do not want to. 
You may decide not to take part in the sub-study, or you may decide to leave this sub-study at any time 
without losing your regular medical care. 
You are not not required to participate in these interviews in order to remain in the rest of the HPTN 
084-1 study. 
 
About the sub-study 
The HPTN 084-1 study is being done to find out if it is safe and acceptable for adolescent women who 
do not have HIV to take a new HIV medicine called cabotegravir (CAB) as PrEP to prevent HIV. This 
sub-study will ask young women what they like and do not like about getting CAB injections. We will 

 
HPTN 084-01, FINAL Version 1.0 
 
109 of 117 
14 October 2019 
also ask questions to find out what makes some young women more or less interested in starting PrEP. 
Finally, we will ask about difficulties you had getting CAB injections and things that made that easier. 
 
Entering the sub-study 
In order to understand better what makes it easier or harder for young women in this study to get CAB 
injections as directed, we will be doing interviews with up to 10 young women at participating sites. 
You have been selected to take part in one interview sometime after your last CAB injection.  
 
What will happen during the interview 
The interview will be led by a member of the research team that you do not work with during the study. 
It should take about 1 hour and your parent/guardian will not be there. [To be modified to reflect site 
practices: The interview will take place in a location that the study staff have determined will provide 
you with privacy and confidentiality such as the clinic, or another appropriate place. The study team 
will talk with you about this so you know where to go for the interview].  
 
During the interview we will ask you questions about:  
• How and when you decided to join the HPTN 084-1 study,  
• Whether you feel that you personally are at risk of HIV,  
• How you made daily pill-taking part of your routine in Step 1,  
• Where you kept your CAB pills,  
• Whether you talked to your family members, peers, or partner(s) about being in this study or 
getting CAB injections in Step 2,  
• If you had any bad effects from the CAB injections, and if this influenced your decision to keep 
getting the injections,  
• If you are taking daily TENOFOVIR/EMTRICITABINE (TRADE NAME: TDF/FTC, 
TRUVADA®) pills, how you feel about being on PrEP, and  
• Other related topics.  
 
If any of the questions make you upset, either you or the interviewer may stop the interview at any time. 
You will also be provided with contact and referral information if any of the questions raise issues that 
you would like to talk about later. 
 
Benefits of the sub-study 
There may be no benefit from being in the sub-study. You may not receive any other direct benefit from 
being in this part of the study; however, you or others in your community may benefit from this study 
later.

There is little risk from the interview. To minimize any discomfort and to protect your privacy the 
interview will be conducted in a private area that will allow you to speak comfortably without being 
overheard. Although we hope that you will be comfortable answering all of the questions openly and 
honestly, please keep in mind that you may refuse to answer any of the questions, or stop the interview 
completely, at any time. The greatest risk may involve your privacy and confidentiality. The steps that 
the study team have taken to protect your privacy are described below.

INTRODUCTION 
You are being asked to take part in a sub-study of the HPTN 084-1 research study that involves 
completing an interview. Joining this sub-study is voluntary. You may refuse to join, or you may 
withdraw your consent to be in this sub-study for any reason. Before you decide whether to join this 
sub-study we would like to explain the purpose of the interview, the risks and benefits to you and what 
is expected of you.  
  
This consent form gives information about being in the sub-study. We will help you to understand the 
form and answer your questions before you sign this form. Once you understand the sub-study, and if 
you agree to take part, you will be asked to sign your name or make your mark on this form. You will be 
offered a copy of this form to keep.  
 
Participation is voluntary 
Before you learn about the sub-study, it is important that you know the following: 
Your participation is voluntary. You do not have to take part in this sub-study if you do not want to. 
You may decide not to take part in the sub-study, or you may decide to leave this sub-study at any time 
without losing your regular medical care. 
You are not not required to participate in these interviews in order for your child to to remain in the rest 
of the HPTN 084-1 study. 
 
About the sub-study 
The HPTN 084-1 study is being done to find out if it is safe and acceptable for adolescent women who 
do not have HIV to take a new HIV medicine called cabotegravir (CAB) as PrEP to prevent HIV. This 
sub-study will ask young women what they like and do not like about getting CAB injections. We will 
also ask their parents/guardians questions to find out what it is like to have a child getting CAB 
injections and things that made that easier, and that is why you have been chosen to take part.

It should take about 1 hour and your child will not be there. [To be modified to reflect site practices: The

• If your child had any bad effects from being in the HPTN 084-1 study, and if this influenced 
your decision to keep coming for the study visits,  
• Other related topics.

you would like to talk about later.
