See if PrEP Choice helps young people start and stick with HIV prevention methods
Official title: Combatting HIV Or Other STIs Early (CHOOSE): An Integrated Strategy of Pre-Exposure Prophylaxis (PrEP) Mobile Health (mHealth) Support and Doxycycline Post-Exposure Prophylaxis (DoxyPEP)
Run by Westat · NCT07510048 · Data updated 2026-11-12
This trial tests whether the PrEP Choice package helps 13-24 year-olds in the U.S. begin and continue using PrEP or DoxyPEP for HIV prevention.

Is this trial a fit for you?
✓Likely a good fit
Young people aged 13-24 who are not on PrEP, are at elevated HIV acquisition risk, own a smartphone, and can participate at an ATN site.
✕Probably not a fit
Individuals not interested in PrEP or unable to use PrEP options may derive little or no benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is an individual-level randomized trial with a wait-list control to evaluate the PrEP Choice integrated mHealth package and its cost in promoting PrEP initiation and adherence among young people. Participants receive counseling and a PrEP/DoxyPEP handout, with the intervention group starting PrEP Choice at enrollment and the control group at 9 months, followed for 18 months. PrEP options include daily TDF/FTC, TAF/FTC, event-driven TDF/FTC, CAB-LA injections, and LEN injections, with regimen changes allowed. The study is conducted through ATN site networks at multiple U.S. locations and aims to assess uptake, persistence, and acceptability of PrEP and DoxyPEP. Lead sponsor is Westat, with NICHD, NIDA, and NIMH as collaborators.
Why it matters
Potential benefit: If successful, participants may experience higher initiation and longer adherence to HIV prevention strategies, potentially reducing HIV risk.
How similar studies have gone: Prior related work suggests multi-modal PrEP support can improve uptake and persistence, though this exact package is being tested.
