More details

This study is part of a master study. The goal of master protocol (GSUS-544-5905, NCT05585307) is to learn how novel antiretrovirals (medicines that stop the virus from multiplying) affect the human immunodeficiency virus-1 (HIV-1) infection in people living with HIV (PWH). Substudy GS-US-544-5905-04 is to learn more about study drug GS-1219, safety, pharmacokinetics (PK) (how GS-1219 is absorbed, modified, distributed, and removed from the body of the participants), and antiviral activity in Participants With HIV-1.

Purpose

Study of GS-1219 in Participants With HIV-1

Interventions

Intervention 1

Comments about the studied populations

Key Inclusion Criteria: All Substudies: * Plasma human immunodeficiency virus-1 (HIV-1) ribonucleic acid (RNA) ≥ 5000 copies/mL but ≤ 400,000 copies/mL at screening. * Cluster of differentiation 4 (CD4) cell count \> 200 cells/mm\^3 at screening. * Antiretroviral (ARV) treatment-naive or treatment-experienced but naive to the investigational ARV drug class being investigated in the given substudy and have not received any ARV within 12 weeks of screening, including medications received for pre-exposure prophylaxis (PrEP) or postexposure prophylaxis (PEP) (note that current or prior receipt of long acting (LA) parenteral ARVs such as monoclonal antibodies (mAbs) targeting HIV-1, injectable cabotegravir (CAB), injectable rilpivirine (RPV) or injectable Lenacapavir (LEN) is exclusionary). *
