Official Title
A Phase IIb, Randomized, Partially Blind, Active Controlled, Dose-range Finding Study of GSK3640254 Compared to a Reference Arm of Dolutegravir, Each in Combination With Nucleoside Reverse Transcriptase Inhibitors, in HIV-1 Infected Antiretroviral Treatment-naive Adults

Study Population Description
(Adult, Older Adult) with Documented HIV Infections
Infection with HIV-1 continues to be a serious health threat throughout the world, with more than 40 million individuals infected worldwide. The current standard of care treatment for HIV-1 is combination anti-retroviral therapy (cART) with recommendations to start regardless of cluster of differentiation 4 (CD4) plus (+) T-cell count, committing people living with HIV to lifelong, lifesaving therapy. However, the chronic exposure to cART has identified anti-retroviral (ARV)-associated long-term toxicities (central nervous system [CNS] or cardiovascular [CV] metabolic effects, renal disease), creating a need to address and prevent these co-morbidities. GSK3640254 is a next-generation HIV-1 maturation inhibitor (MI) and has completed a short-term, monotherapy, proof of concept (POC) Phase 2a study. This is a phase 2b, randomized, multicenter, parallel group, partially blind (to GSK3640254 doses [100, 150 and 200 milligrams {mg}]), active controlled clinical trial. It will aim to investigate the safety, efficacy and dose-response of GSK3640254 compared to dolutegravir (DTG), each given in combination with 2 Nucleoside Reverse Transcriptase Inhibitors (NRTIs) (abacavir/lamivudine [ABC/3TC] or emtricitabine/tenofovir alafenamide [FTC/TAF]), in approximately 240 treatment-naïve HIV-1 infected adults. In the experimental arms, GSK3640254 will be administered in 3 blinded doses until the last participant completes their Week 48 study visit (Week 48 Secondary Endpoint study milestone). Thereafter, participants whose most recent HIV-1 ribonucleic acid (RNA) less than (<)50 copies/milliliters (c/mL) in the GSK3640254 arms will move into the Non-Randomised Phase and will be switched from their blinded dose to the open label optimal dose. Simultaneously, these participants will also be switched from their dual NRTI therapy to DTG. The total study duration will be approximately 7 years.
