A Phase 3 interventional study of CAB LA in HIV Infections, sponsored by ViiV Healthcare. Active, not recruiting at 33 sites in 12 countries. Per ClinicalTrials.gov, last updated 2026-11-05.
Sponsored by ViiV Healthcare (part of GlaxoSmithKline) · Phase 3, Interventional, and Prevention
The purpose of this study is long-term evaluation of long-acting injectable cabotegravir (CAB LA) for HIV pre-exposure prophylaxis (PrEP) in eligible participants who have completed DAIDS (Division of AIDS) sponsored studies HPTN 083 and HPTN 084 and associated sub-studies. Participants will continue receiving CAB LA and be followed for new HIV diagnosis, SAEs (serious adverse events), Grade 3 and Grade 4 ISRs (injection site reactions), and AEs (adverse events) leading to withdrawal.
4,734 studies on the registry are indexed under HIV Infections; 244 are open to participants now.
This study's enrollment of 2,998 is above the median of 80 across 3,489 interventional studies indexed under HIV Infections.
Browse HIV Infections studies →ViiV Healthcare is the lead sponsor of 265 studies on the registry; 16 are open to participants now.
Of its 71 completed or terminated interventional studies of FDA-regulated products, 53 (75%) have results posted.

Type of participant
Participants must have recently completed or be currently enrolled and ongoing in one of the following studies on the CAB LA arm:
Participants that completed study participation ≥3 months ago must be discussed with the Medical Monitor prior to enrolment.
Participants who have prematurely withdrawn from prior CAB PrEP studies cannot enroll into this study.
Participants must have nonreactive HIV tests at Screening (rapid test, immunoassay [antigen/antibody] test and HIV-1 RNA results must all be available and nonreactive) and Day 1 (at least one of rapid test and immunoassay [antigen/antibody test] results must be available and nonreactive). Participants who have one or more reactive or positive HIV test result(s) will not be enrolled, even if subsequent confirmatory testing indicates they are not HIV-infected.
Sex
Males and Females:
All participants who are engaging in sexual activity should be counselled on safer sexual practices including the use and benefit/risk of effective barrier methods (e.g., male condom) and on the risk of acquiring HIV and other STIs.
Females:
Cisgender female participants who are of and who are engaging in sexual activity that could lead to pregnancy, must talk to the investigator about recommended options. Contraception will be optional in this study. Condoms are recommended in addition, because their appropriate use is the only contraception method effective for preventing HIV-1 transmission.
Pregnant participants from the HPTN 084 study are eligible to enroll into this study if they meet all eligibility criteria.
Exclusion Criteria:
Concurrent conditions/medical history (includes liver function)
Anticipated need for therapy with interferon or any drugs that have potential for adverse drug: drug interactions with study treatment throughout the entire study period.
Relevant habits
Any condition (i(including but not limited to substance use disorder) that would, in the opinion of the site investigator, place the participant at an unacceptable risk of injury or render the participant unable to meet the requirements of the protocol.
Other
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
HIV
