Sponsor: Oswaldo Cruz Foundation
Conditions: Contact With or Exposure to Human Immunodeficiency Virus
Interventions: Lenacapavir long-acting, Tenofovi-Emtricitabine (TDF/FTC) tablet
Countries: Brazil
The goal of this study is to learn how well long-acting lenacapavir works to prevent human immunodeficiency virus (HIV) infection in people at higher risk of getting HIV in Brazil. The study will also learn about safety, continued use over time, and whether people prefer this option compared to daily oral pre- exposure prophylaxis (PrEP). The main questions it aims to answer are: How many participants get HIV while using long-acting lenacapavir? How safe is long-acting lenacapavir in real-world health services? How many participants continue using their chosen prevention method over time? What factors help or make it harder for participants to stay on prevention? Researchers will compare two HIV prevention options to understand how they work in routine care: Long-acting lenacapavir, given as an injection under the skin every 6 months, Daily oral pre-exposure prophylaxis (PrEP), taken as a pill containing tenofovir disoproxil fumarate and emtricitabine, Participants will choose the prevention option they prefer after receiving counseling. This is not a randomized study. Researchers will follow participants for up to 2 years. Participants will: Receive either an injection every 6 months or take a daily pill, Visit the clinic regularly for HIV testing and health checkups, Receive testing and treatment for sexually transmitted infections, Answer questions about their health, medication use, and experiences, Receive prevention counseling and condoms. This study will help health services understand how to offer long-acting HIV prevention in Brazil and how to better support people who want to prevent HIV infection.
