Gilead study of GS-3242 with Lenacapavir for people starting HIV treatment compared with Biktarvy

Official title: An Operationally Seamless Phase 2/3 Randomized, Open-label, Active-Controlled Study Evaluating the Safety and Efficacy of an Injectable Regimen of GS-3242 in Combination With Lenacapavir Versus Biktarvy (Bictegravir/Emtricitabine/Tenofovir Alafenamide) in Treatment-Naive People With HIV-1

Run by Gilead Sciences · NCT07708727 · Data updated 2026-11-12

This study tests whether injecting GS-3242 with Lenacapavir can work as well as Biktarvy for people newly starting HIV treatment.

Is this trial a fit for you?

Likely a good fit

Treatment-naive adults with HIV-1 infection and HIV RNA ≥ 500 copies/mL, who have not previously used Lenacapavir or GS-3242 and have not used long-acting injectable ARV therapies.

Probably not a fit

People who do not respond to the injectable regimen or have contraindications to the study drugs may not see benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 2/3 interventional trial evaluating an injectable regimen of GS-3242 plus Lenacapavir versus the standard oral Biktarvy in treatment-naive adults with HIV-1. Phase 2 includes Part A and Part B to compare short-term efficacy at 26–35 weeks across multiple treatment groups. Phase 3 follows to assess long-term effectiveness at 52 weeks. Interventions include GS-3242 and Lenacapavir in both tablet and injectable forms alongside B/F/TAF, with primary endpoints focused on virologic efficacy. Eligibility requires HIV-1 RNA ≥ 500 copies/mL at screening and no prior LEN or GS-3242 exposure, among other criteria, and several sites are involved in the United States.

Why it matters

Potential benefit: If successful, participants and future patients may have a new injectable treatment option that could simplify HIV therapy while maintaining viral suppression.

How similar studies have gone: Prior short-acting and long-acting antiretroviral strategies have shown promise, but this exact injectable GS-3242/Lenacapavir approach in treatment-naive patients is being studied to establish efficacy versus B/F/TAF.
