简要总结
The LYPS intervention is a multi-level intervention that combines: a) structural-level delivery of PrEP and PrEP services by a community health professional (CHP) at a designated place in the community being offered by the SC where PrEP is not yet provided (e.g., participant's home, community partner location, or traveling mobile van), with b) an individual-level mobile application (app) to support PrEP adherence and persistence between CHP visits.
详细描述
LYPS is a two-arm randomized controlled trial (RCT) to assess the efficacy of the LYPS intervention. Up to 272 participants will be randomized in a 1:1 ratio to receive either the LYPS intervention or enhanced standard of care (eSOC) (136 participants per arm). The eSOC control condition will consist of usual clinic-based PrEP care and access to a limited number of LYPS app components. Participants will complete four research assessments, at Enrollment and Weeks 12, 24, and 36, that include computer-assisted self-interviews (CASIs) and blood collection. CASIs will collect information including, but not limited to, demographics, PrEP adherence and persistence, PrEP clinic visit attendance, PrEP knowledge and attitudes, PrEP self-efficacy, PrEP stigma, and psychosocial variables, questions that evaluate components of the LYPS intervention, tailored for intervention and eSOC conditions. Blood (dried blood spot [DBS] and plasma) will be collected to evaluate PrEP drug concentrations and stored for additional study-related testing.
All participants will receive daily oral PrEP, oral PrEP taken using a 2-1-1 dosing strategy, or injectable PrEP based on their preference and in consultation with their PrEP provider. There is no randomization involved for PrEP provision and participants are allowed to switch between oral and injectable PrEP or vice versa during the study. PrEP care visits (quarterly for those on oral PrEP and two monthly injections followed by an injection every two months for those on injectable PrEP) will include clinical labs such as HIV and STI testing and focused physical exams for signs and symptoms of HIV infection. Other relevant clinical data collected as part of the participant's PrEP clinical care will also be collected.

研究组 & 干预措施
Enhanced Standard of Care (eSOC) Control Condition
Usual standard of care clinic-based PrEP, enhanced with access to a limited number of LYPS app components, including basic PrEP adherence information and study visit reminders.
干预措施: Enhanced Standard of Care (Other)
LYPS Intervention
PrEP and PrEP care will be delivered to youth in the communities where they live through a Community Health Professional (CHP) (e.g., a nurse or other qualified health care professional home, friend's home, community venue or clinic, mobile health clinic), supplemented by a mobile app to provide real-time intervention between CHP visits.
干预措施: LYPS (Other)
结局指标
主要结局
PrEP adherence at 6 months
时间窗: 6 months
Determine adherence outcomes as measured by blood will be tailored for oral PrEP modality (daily oral or 2-1-1) and target vs. non-target PrEP concentration thresholds (depending on regimen) will be examined. Adherence outcomes for participants on injectable PrEP will be determined by the timely (± 1 week for the second injection; ± 2 weeks for any subsequent injection) administration of injections.
PrEP persistence at 6 months
时间窗: 6 months
Access persistence measures as based on 1) participant's self-report of currently taking PrEP (daily or 2-1-1) or having received last shot of injectable PrEP, and 2) has an active prescription for PrEP based on study records or drug level associated with use at 6 months.
次要结局
- PrEP adherence at 9 months(9 months)
- PrEP persistence at 9 months(9 months)
