Combined mobile PrEP support and virtual therapy for HIV‑negative men who have sex with men using meth
CHAMPION - Combining HIV And Stimulant Prevention and Treatment Interventions Optimized for HIV-Negative MSM

What this research studies
If you join, you would be an HIV‑negative man who has sex with men, is 21 or older, and uses methamphetamine. The program pairs a PrEP support app (PREPAPP) with virtual cognitive behavioral therapy (CBT4CBT) and compares this package to a usual-care waitlist. One hundred participants will be randomized and followed for six months with monthly behavioral checks and objective measures of PrEP adherence. The goal is to see whether the combined mobile and therapy approach is doable, acceptable, and helps people keep taking PrEP.
Who could benefit from this research
Good fit: HIV‑negative men who have sex with men, aged 21 or older, who use methamphetamine and are eligible for or interested in starting or continuing PrEP are the ideal candidates.
Not a fit: People who are HIV‑positive, younger than 21, do not use stimulants, are not eligible for PrEP, or cannot use a smartphone or attend virtual sessions may not benefit from this program.
Why it matters
Potential benefit: If successful, this approach could help people on PrEP be more consistent with their medication and reduce HIV risk linked to meth use.
How similar studies have performed: Mobile health apps and virtual CBT have shown promise separately for improving PrEP use and reducing stimulant-related harms, but combining these specific tools for meth‑using MSM is a newer approach.
