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

Официальное название

A First-in-Human Phase 1b, Single-Blind, Placebo-controlled Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD) Study to Evaluate Safety and Pharmacokinetics of GS-0415 in People With HIV-1 Who Are Virologically Suppressed on Antiretroviral Treatment

Обзор

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.
