Study of an Injectable Regimen of GS-3242 With Lenacapavir Compared to Biktarvy in People New to HIV-1 Treatment
What this study is about
The study will have two portions: Phase 2 and Phase 3. Phase 2 will further have 2 parts: Part A and Part B. The goal of Phase 2, Part A is to assess the effectiveness of study drugs GS-3242 plus Lenacapavir (LEN) versus Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF)), in people with HIV-1 (PWH) who are new to treatment.
View original scientific description
The study will have two portions: Phase 2 and Phase 3. Phase 2 will further have 2 parts: Part A and Part B. The goal of Phase 2, Part A is to assess the effectiveness of study drugs GS-3242 plus Lenacapavir (LEN) versus Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF)), in people with HIV-1 (PWH) who are new to treatment. This will be done in Treatment Groups 1, 2 and 3 at Week 35. The goal of Phase 2, Part B is to compare the effectiveness of study drugs, GS-3242 and LEN versus B/F/TAF in Groups 4 and 3 at Week 26. The goal of Phase 3 is to assess the long-term effectiveness of study drug GS-3242 and LEN versus B/F/TAF, at Week 52. The primary objectives of this study are: Phase 2, Part A: To evaluate the efficacy of intramuscular (IM) GS-3242 plus IM LEN versus B/F/TAF in treatment-naive people with HIV-1 (PWH) in Treatment Groups 1, 2, and 3 at Week 35. Phase 2, Part B: To evaluate the efficacy of IM GS-3242 plus IM LEN versus B/F/TAF in treatment-naive PWH in Treatment Groups 4 and 3 at Week 26. Phase 3: To evaluate the efficacy of IM GS-3242 plus IM LEN versus B/F/TAF in treatment-naive PWH at Week 52.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
