Efficacy of a Community-based PrEP Uptake Intervention for People Who Inject Drugs (PWID) in the US Northeast
Brown University
Summary
This randomized controlled trial will test the efficacy of "PrEP for Health," a behavioral intervention to improve the use of antiretroviral pre-exposure prophylaxis (PrEP) among at-risk people who inject drugs (PWID) in two syringe service program (SSP) settings in Lawrence and Boston/Cambridge, Massachusetts. The investigators will equally randomize 200 PWID to receive either (a) the "PrEP for Health" intervention condition involving theory-informed HIV and PrEP education, motivational interviewing, problem-solving and planning, and ongoing patient navigation (n=100), or (b) the standard of care condition involving PrEP information and referrals (n=100). Successful PrEP uptake (via medical/pharmacy records), post-treatment PrEP adherence (assessed at 3 months via drug levels in hair), and longer-term PrEP adherence (assessed at 6 and 12 months via drug levels in hair) will be evaluated. The degree to which intervention efficacy occurs through specific conceptual mediators and differs according to hypothesized moderators will also be evaluated.
Description
The overall goal of this proposal is to evaluate the efficacy of the "PrEP for Health" navigator delivered behavioral intervention in improving PrEP uptake (via medical/pharmacy records), post-treatment PrEP adherence (assessed at 3 months via drug levels in hair), and longer-term PrEP adherence (assessed at 6 and 12 months via drug levels in hair) among PWID in SSPs. Eligible PWID (n=200 total; 100 recruited from each study site) will be equally randomized to an active PrEP for Health intervention arm (n=100) or a Standard of Care control condition (n=100). Assessments will be conducted at ba…
