the stay study: a demonstration project advancing prep delivery in the san francisco bay area transgender community

Conditions: Transgender Persons; Pre-Exposure Prophylaxis

Summary: the stay study is a multi-site, open-label hiv pre-exposure prophylaxis (prep) demonstration project for advancing prep delivery in the san francisco bay area transgender community. approximately 188 hiv-uninfected participants will be enrolled at 4 sites in san francisco and fremont and will be provided truvada to take orally once daily as prep.

prep stands for pre-exposure prophylaxis, an hiv prevention method that involves hiv negative people taking antiviral drugs daily to try to help prevent hiv infection. studies with men who have sex with men (msm) and transgender women showed that people who took prep were less likely to become infected with hiv than those who did not take it. the main purpose of this prep demonstration project is to make prep accessible to people in the transgender community. as part of this project, we will study whether transgender women and men are interested in taking prep, and, if so, for how long and how frequently they take the medication and how these relate to demographics (such as race, age, and education). we will also assess reasons for stopping prep and measure sexual behaviors of participants in the demonstration project.
