PrEP Intervention for People Who Inject Substances and Use Methamphetamine

Sponsor: San Francisco Department of Public Health

View on ClinicalTrials.gov

Summary

In this study, "PrEP Intervention for people who Inject Substances and Use Methamphetamine" (PRIME), we propose to assess if using video directly observed therapy with real-time contingency management (VDOT-CM) may help people assigned male sex at birth who inject methamphetamine adhere to PrEP. We will randomize 140 adults who use methamphetamine, are HIV-negative, and have recently engaged in a sexual HIV risk behavior to VDOT-CM or counseling alone for 24 weeks. The study aims are to (1) determine the efficacy of VDOT-CM compared to counseling alone for PrEP adherence, (2) evaluate the acceptability of PrEP and adherence support strategies among the cohort, and (3) compare injection or chemsex and sexual HIV risk behavior before and during PrEP use. We hypothesize that participants randomized to VDOT-CM will have superior adherence to PrEP. We also hypothesize that participants will describe barriers to and facilitators of PrEP adherence, and those who are randomized to VDOT-CM will consider it an acceptable PrEP adherence support strategy. Finally, we do not expect to find increased injection, chemsex, or sexual risk behaviors for HIV among study participants after they begin taking PrEP.

Interventions

BEHAVIORAL

Video directly observed therapy with contingency management

PrEP adherence will be assessed by visual recognition software during video capture and reviewed for confirmation by study staff, ensuring that videos demonstrate study medication dosing by participant. Participants will receive small financial incentives upon confirmation of dosing.

BEHAVIORAL

Integrated Next-Step Counseling

Integrated Next-Step Counseling combines support for behavioral strategies that reduce sexual and injection-related HIV risk and do not involve PrEP, with strategies to support PrEP adherence in brief, client-centered conversations.
