Optimizing PrEP adherence in sexual minority men who use stimulants

Project: Research project

Project Details

Description

Abstract Among men who have sex with men (MSM), there is an urgent need to optimize the unprecedented clinical and public health benefits of pre-exposure prophylaxis (PrEP) to prevent HIV with those who use stimulants (i.e., methamphetamine, cocaine, and crack-cocaine). Stimulant-using MSM display 3-6 fold faster rates of HIV seroconversion, and one-in-ten MSM with newly diagnosed HIV infection report recent stimulant use. Findings from our team and others also demonstrate that stimulant use is a key obstacle to PrEP adherence and persistence. Stimulant-using MSM have a 3-fold greater rate of disengagement from PrEP care and 5-fold greater odds of sub-optimal PrEP adherence. The proposed multi-site randomized controlled trial (RCT) will leverage a promising intervention model of delivering a positive affect intervention during contingency management (CM), which we have recently demonstrated achieves durable and clinically meaningful reductions in viral load among HIV+, methamphetamine-using MSM. In the proposed multi-site RCT, we plan to test whether delivering an Affect Regulation Treatment to Enhance Medication Intervention Success (ARTEMIS) positive affect intervention during smartphone-based CM for directly observed PrEP doses achieves more durable reductions in HIV acquisition risk over 12 months. HIV acquisition risk (the primary outcome) will be operationalized as tenofovir diphosphate (TFV-DP) levels
