Overview

About This Project

The GS-US-412-5624 study is a Phase 3, multicentre, randomized, double-blind clinical trial sponsored by Gilead Sciences to evaluate the safety and efficacy of twice-yearly subcutaneous lenacapavir (LEN) and daily oral emtricitabine/tenofovir alafenamide (F/TAF) for HIV pre-exposure prophylaxis (PrEP) in adolescent girls and young women at risk of HIV infection.

The study compares these interventions with the current standard oral PrEP regimen while assessing safety, HIV prevention efficacy, adherence, and participant preferences.
