Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical study is to learn more about the experimental drugs GS-1720 and GS-4182; to compare the combination of GS-1720 and GS-4182 with the current standard-of-care treatment bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF, BVY), to see if the combination of GS-1720 and GS-4182 is safe and if it works for treating human immunodeficiency virus type 1 (HIV-1) infection.

This study has two phases: Phase 2 and Phase 3.

The primary objectives of this study are:

Phase 2: To evaluate the efficacy of switching to oral weekly GS-1720 in combination with GS-4182 versus continuing BVY in virologically suppressed people with HIV-1 (PWH) at Week 24.

Phase 3: To evaluate the efficacy of switching to oral weekly GS-1720/GS-4182 Fixed-dose combination (FDC) tablet regimen versus continuing BVY in virologically suppressed PWH at Week 48.

Study Groups

Phase 2: GS-1720 + GS-4182 (Treatment Group 1)

Participants who have been virologically suppressed on bictegravir/emtricitabine/tenofovir alafenamide (BVY) will switch to GS-1720 (650 mg tablet) and GS-4182 (300 mg tablet) coadministered. Participants will receive a 1-day loading dose of GS-1720 (1300 mg) and GS-4182 (600 mg) on Day 1. Thereafter, participants will take weekly doses of single agent GS-1720 (650 mg) and GS-4182 (300 mg) coadministered for at least 48 weeks.

Phase 2: Bictegravir/emtricitabine/tenofovir alafenamide (BVY) (Treatment Group 2)

Participants who have been virologically suppressed on bictegravir/emtricitabine/tenofovir alafenamide (BVY) will continue receiving BVY daily for at least 48 weeks.

Phase 2 Extension Phase: GS-1720/GS-4182 Fixed-dose Combination (FDC)

At the end of the randomized treatment, Phase 2 participants will be given the option to participate in the Extension Phase. Phase 2 Treatment Group 1 will switch to GS-1720/GS-4182 FDC weekly. Phase 2 Treatment Group 2 will receive a loading dose of GS-1720/GS-4182 FDC on Extension Phase Day 1 then, GS-1720/GS-4182 FDC weekly. Participants who choose to enter the Extension Phase will receive GS-1720/GS-4182 FDC tablets until the product becomes available or until Gilead Sciences elects to discontinue the study, whichever occurs first.

Phase 3: GS-1720/GS-4182 FDC + Placebo to Match (PTM) BVY (Treatment Group 1)

Participants who have been virologically suppressed on BVY will switch from BVY to GS-1720/GS-4182 FDC tablets weekly + placebo-to-match (PTM) BVY once daily. In addition, participants will receive a 1-day loading dose regimen of GS-1720/GS-4182 FDC on Day 1.

Participants will receive treatment for at least 96 weeks.

After the end of blinded treatment, Phase 3 participants will be given the option to participate in the Extension Phase. Phase 3 Treatment Group 1 will switch to GS-1720/GS-4182 FDC weekly. Phase 3 Treatment Group 2 will receive a 1-day loading dose of GS-1720/GS-4182 FDC on Extension Phase Day 1, then GS-1720/GS-4182 FDC weekly. Participants who choose to enter the Extension Phase will receive GS-1720/GS-4182 FDC tablets until the product becomes available or until Gilead Sciences elects to discontinue the study, whichever occurs first.
