A Randomized, Double-Blind (Sponsor-unblinded), Placebo-Controlled, Adaptive Trial to Investigate the Antiviral Effect, Safety, Tolerability and Pharmacokinetics of GSK3640254 in HIV-1 Infected Treatment-Naïve Adults
In Brief
A Phase 2 clinical trial evaluating GSK3640254 and Placebo matching GSK3640254 Mesylate salt for HIV Infections. Completed, enrolled 34 participants across 23 sites in 6 countries.
Detailed Summary
Infection with HIV-1 continues to be a serious health threat throughout the world. Chronic exposure to combination anti-retroviral therapy identified anti-retroviral associated long-term toxicities. Hence, there is a need to prevent these co-morbidities. GSK3640254 is a next-generation HIV-1 Maturation Inhibitor (MI) which may be effective for HIV-1 infection. This study will evaluate the antiviral effect, safety, tolerability and pharmacokinetics/ pharmacodynamics of GSK3640254 in HIV-1 infected treatment-naive adults. This study will consists of two parts; Part 1 and Part 2. Part 1 will evaluate two active doses of GSK3640254, 200 milligrams (mg) (Cohort 1) and 10 mg (Cohort 2) along with placebo to match GSK3640254 Mesylate salt. Part 2 will evaluate three active doses of GSK3640254. Dose level 1 of GSK3640254 that can provide at least 30 percent of the maximum effect (Cohort 1), dose level 2 of GSK3640254 that can provide at least 75 percent of the maximum effect (Cohort 2) and dose level 3 of GSK3640254 that can provide at least 90 percent of the maximum effect (Cohort 3). These doses are anticipated to be 5 mg, 40 mg and 100 mg respectively, but could be modified based on data obtained in Part 1. Subjects will also receive placebo to match GSK3640254 Mesylate salt in Part 2 of the study. All doses will be administered after a moderate fat meal. This study will consist of Screening period (up to 14 days), Treatment period (Day 1- Day 10), post-dose Follow-up (Day 11- Day 17) and final Follow-up (Day 18-24). A total of approximately 34 subjects will be enrolled, of which, 14 subjects will be randomized in Part 1 and 20 in Part 2 of the study. Six subjects will be enrolled in each of the active dose cohorts and 2 subjects will be enrolled in each of the placebo cohorts.
