Trial Purpose and Description

A non-randomized, open-label design will be utilized to test the feasibility, acceptability, and preliminary efficacy of the Expanding PrEP Implementation in Communities of PWID (EPIC-P) intervention among high-risk people who inject drugs (PWID) with opioid dependence (N=100). Since the aim of this pilot study is to establish whether the EPIC-P intervention is feasible/acceptable among at-risk PWID in a community-based setting, proposed is a non-comparative design. With the hopes to target PWID who are not linked with existing harm reduction services, proposed is to recruit participants using respondent driven sampling (RDS), a chain referral method with demonstrated success in recruiting hard-to-reach populations. Initial RDS participants, called "seeds," will be carefully recruited from the community where the study team leadership have built a well-established relationship. Participants enrolled in the study will be assessed at baseline and will be followed for 9 months (with follow-up assessments at 3- and 6-months) by trained research assistants. Importantly, structured interviews will be conducted at follow-up visits to examine the barriers and facilitators and feedback about optimal implementation of the EPIC-P intervention.
