Is this trial a fit for you?

Likely a good fit

Ideal participants are youths aged 13–24 who engage in sex in the past year, are not living with HIV, and own an Android or iPhone with English fluency.

Probably not a fit

People who do not have access to PrEP services or who cannot take PrEP due to contraindications may not benefit.

What this trial studies

This randomized trial will enroll up to 272 participants aged 13–24 who are at risk for HIV and not living with HIV. Participants are assigned to LYPS, a multi-level intervention with community-based PrEP delivery plus a mobile app to support adherence, or to enhanced standard of care with usual clinic PrEP and limited app access. PrEP choices (daily oral, 2-1-1 dosing, or injectable) can be switched during the study based on preference and medical advice, and visits include biospecimen collection to measure drug concentrations. The study uses four assessments over 36 weeks to track adherence, clinic attendance, knowledge, attitudes, self-efficacy, stigma, and other psychosocial factors.

Why it matters

Potential benefit: If successful, LYPS could improve PrEP adherence and persistence among youth, reducing HIV risk.

How similar studies have gone: Prior studies have shown that combined service delivery and digital support can improve PrEP engagement, but this specific youth-focused, multi-site approach is novel.
