Mobile Vehicle-Based Delivery of Lenacapavir Pre-Exposure Prophylaxis in Los Angeles County

Recruiting now

Conditions studied: HIV Prevention

In brief

This project evaluates the implementation strategy of the delivery of lenacapavir pre-exposure prophylaxis (LEN PrEP) - a newly available long-acting, injectable medication for human immunodeficiency virus (HIV) prevention - via a mobile health van model for people who are unstably housed in Los Angeles County (LAC). People who are unhoused or are facing housing instability experience significant barriers to accessing HIV prevention care in traditional clinic settings. In 2022, approximately 13% of newly diagnosed HIV cases in LAC were experiencing homelessness, a 36% increase over the prior period. The study will work with the University of California, Los Angeles (UCLA) Health's Homeless Healthcare Collaborative (HHC), which operates mobile health vans staffed by clinicians, social workers, and community health workers, to bring LEN PrEP directly to community settings, such as shelters, encampments, community centers, and transitional housing facilities. This study has three primary aims: 1. Characterize uptake of LEN PrEP among unstably housed people in LAC receiving health services via HHC's mobile program. 2. Evaluate how many study participants stay on LEN PrEP through 52 weeks. 3. Understand costs, acceptability, and sustainability of the mobile LEN PrEP delivery model.
