PrEP goes local: Community-Based HIV prevention trial launches in rio
NCT ID NCT07584122
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to make HIV prevention easier to access for underserved groups in Rio de Janeiro, such as gay and bisexual men, transgender women, and sex workers. Instead of requiring clinic visits, participants can get daily PrEP pills and support through community organizations, mobile units, or telehealth. Researchers will see if this approach helps more people start and stay on PrEP, with the goal of reducing new HIV infections.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tenofovir Disoproxil Fumarate/Emtricitabine (TDF/FTC) oral PrEP
- What this could lead to
- If successful, this could show that offering PrEP in community settings helps more at-risk people start and stay on HIV prevention, reducing new infections in underserved areas.
- What could go wrong
- This is an early feasibility study with 400 participants, so results may not apply broadly. Daily pill adherence can be challenging, and the study does not directly measure HIV infection rates.
