Study of GS-0415 and How It Works in People With HIV

The goals of this clinical study are to learn more about the study drug GS-0415, safety, tolerability, and pharmacokinetics (PK) of single ascending doses (SAD) and multiple ascending doses (MAD) of subcutaneous (SC) and intravenous (IV) GS-0415 in people with HIV-1 (PWH) on antiretroviral treatment. The primary objectives of this study are to evaluate the safety and tolerability of escalating, single and multiple subcutaneous (SC) and intravenous (IV) doses of GS-0415, administered in PWH who are virologically suppressed on antiretroviral therapy (ART) and to evaluate the pharmacokinetics (PK) of GS-0415.

Key Inclusion Criteria: * Age ≥ 18 years and age ≤ 65 years at screening * On stable antiretroviral (ARV) treatment for ≥ 12 consecutive months prior to screening, throughout the duration of study treatment and follow-up * The following ARV agents are not allowed as part of the current ART regimen: entry inhibitors (maraviroc, enfuvirtide, ibalizumab, or fostemsavir) * Plasma HIV-1 RNA \< 50 copies/mL at screening with at least 2 documented HIV-1 RNA \
