Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The overarching goal of this project is to optimize the PrEP Choice integrated mHealth package and assess the efficacy and cost of PrEP Choice on PrEP initiation and adherence among young people. It is hypothesized that PrEP Choice will improve HIV PrEP uptake and adherence among young people and will be cost-effective to deliver to young people in the United States (U.S.). This study will also assess the uptake, adherence, and acceptability of DoxyPEP among young people.
