CHAMPION: Combining HIV And Meth Prevention and Treatment Interventions Optimized for HIV-Negative MSM

The CHAMPION (Combining HIV And Meth Prevention and Treatment Interventions Optimized for HIV-Negative MSM) study, a randomized controlled trial that aims to pilot test state-of-the-art multi-modal pharmaco-behavioral interventions to increase PrEP adherence among HIV-negative MSM who use meth, versus a waitlist control. The study will enroll 100 HIV-negative MSM with mild or moderate meth use disorder (MUD) and sub-optimal PrEP adherence. The study will follow participants for 6 months. The intervention arm will receive the 6-month mHealth intervention package, CHAMPION, at baseline, while the waitlist control will receive it at month-3 follow-up. Results of this pilot study will determine the viability of combining interventions that reduce meth use and enhance PrEP adherence, informing the direction of future interventions for MSM who use meth.
