About this study
Official title: A Phase 2b/3 Double Blind Safety and Efficacy Study of Injectable Cabotegravir Compared to Daily Oral Tenofovir Disoproxil Fumarate/Emtricitabine For Pre-Exposure Prophylaxis in HIV-Uninfected Men and Transgender Women Who Have Sex With Men
This study will evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).
Read the detailed description
The purpose of this study is to evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).
This study will enroll HIV-uninfected MSM and TGW at risk for acquiring HIV infection. Participants will be followed for a total of 4 years.
This study will take place in three steps. Participants will be randomly assigned to one of two arms:
Arm A:
Step 1: Participants will receive daily oral CAB tablets and daily oral TDF/FTC placebo tablets for 5 weeks.
Step 2: Participants will receive an intramuscular (IM) injection of CAB LA at two time points 4 weeks apart and every 8 weeks thereafter and daily oral TDF/FTC placebo tablets to Week 153.
Arm B:
Step 1: Participants will receive daily oral TDF/FTC tablets and daily oral CAB placebo tablets for 5 weeks.
Step 2: Participants will receive daily oral TDF/FTC tablets and an IM injection of placebo at two time points 4 weeks apart and every 8 weeks thereafter to Week 153.
In Step 3, all participants (Arms A and B) will receive daily oral TDF/FTC tablets starting at Week 153 (last day of Step 2)/Day 0 (first day of Step 3) and continue for 48 weeks.
Participants will attend up to 47 study visits throughout the study. Visits may include physical examinations, blood collection, urine collection, an electrocardiogram (ECG), and rectal swab collection. Some participants may have a bone mineral density-energy x-ray absorptimetry (DXA) scan at select visits.
All participants will be transitioned to locally available HIV prevention services, including services for PrEP, if available, at the end of their participation in the study.
HPTN 083-01 is a sub-study of HPTN 083. The purpose of this study is to evaluate the safety, tolerability, and acceptability of CAB LA for the prevention of HIV among adolescent males. Participants will receive oral CAB for 5 weeks, followed by 29 weeks on CAB LA, then quarterly visits for 48 weeks after final injection. All participants who have received at least one injection will be followed for 48 weeks after their last injection. Total study duration per participant will be approximately 21 months.
HPTN 083-02 is a qualitative sub-study of participants enrolled in HPTN 083. The purpose of this study is to explore potential barriers, facilitators, and potentially modifiable issues related to adherence to clinic visits in the context of injectable PrEP; to learn about preferences and decision making regarding the use of oral versus injectable PrEP, or other biomedical prevention products; and to gather explanatory qualitative data regarding participants' experiences in HPTN 083 to better interpret study results and guide next prevention strategies. Participants in this sub-study will complete one individual semi-structured qualitative interview.

Measured: Assessed at Week 17, 41
Summary of Preference Based on Satisfaction With Study Product
Summary of preference based on satisfaction with study product at Week 17 and Week 41
Measured: Assessed at week 17, 41
Change From Baseline of Mean Z-scores of Bone Mineral Density
Change from baseline of mean standard scores (Z-scores) to week 57 and week 105 in the bone mineral density (BMD) at femoral neck, lumbar spine, and total hip region were summarized using DEXA subset. BMD z-scores from Hologic instrument scans were standardized by race, age, and gender using the Hologic DXA Reference Data. Male reference values were used for men who have sex with men and female reference values for transgender women. A z-score of 0 represents the mean of the analysis population standardized by race, age, and gender. Higher z-scores in BMD indicate a better outcomes. A z-score of -2.0 or lower is generally considered below the expected range, potentially indicating secondary osteoporosis requiring further medical evaluation.
Measured: Measured at enrollment, week 57 and week 105

Step 2: Participants will receive daily oral TDF/FTC tablets and an IM injection of placebo at two time points 4 weeks apart and every 8 weeks thereafter to Week 153.
In Step 3, all participants (Arms A and B) will receive daily oral TDF/FTC tablets starting at Week 153 (last day of Step 2)/Day 0 (first day of Step 3) and continue for 48 weeks.
Participants will attend up to 47 study visits throughout the study. Visits may include physical examinations, blood collection, urine collection, an electrocardiogram (ECG), and rectal swab collection. Some participants may have a bone mineral density-energy x-ray absorptimetry (DXA) scan at select visits.
All participants will be transitioned to locally available HIV prevention services, including services for PrEP, if available, at the end of their participation in the study.
HPTN 083-01 is a sub-study of HPTN 083. The purpose of this study is to evaluate the safety, tolerability, and acceptability of CAB LA for the prevention of HIV among adolescent males. Participants will receive oral CAB for 5 weeks, followed by 29 weeks on CAB LA, then quarterly visits for 48 weeks after final injection. All participants who have received at least one injection will be followed for 48 weeks after their last injection. Total study duration per participant will be approximately 21 months.
HPTN 083-02 is a qualitative sub-study of participants enrolled in HPTN 083. The purpose of this study is to explore potential barriers, facilitators, and potentially modifiable issues related to adherence to clinic visits in the context of injectable PrEP; to learn about preferences and decision making regarding the use of oral versus injectable PrEP, or other biomedical prevention products; and to gather explanatory qualitative data regarding participants' experiences in HPTN 083 to better interpret study results and guide next prevention strategies. Participants in this sub-study will complete one individual semi-structured qualitative interview.

A Phase 2/3 study testing Cabotegravir Oral Tablet, TDF/FTC tablets and CAB LA in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 43 sites in 7 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 43 sites in United States, Peru, Brazil, Thailand, Argentina and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Nov 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Documented Incident HIV Infections During Steps 1 and 2 (time frame: HIV tests at enrollment, weeks 2, 4, 5, every injection visit (every 8 weeks) and every safety visit (2 weeks after each injection visit). Analyzed through week 153 or the date of DSMB decision to unblind all participants, whichever is earliest.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02720094, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2026.
