Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
OTHER	LYPS	The LYPS intervention combines the use of a CHP to deliver PrEP services 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 an android-based smartphone or iphone app to support PrEP use between CHP visits.
OTHER	Enhanced Standard of Care	Clinic-based PrEP services per usual standard of care (e.g., HIV and STI testing, clinical assessments for signs and symptoms of HIV and PrEP safety) with access to a limited number of LYPS app components, including basic PrEP adherence information and study visit reminders.
