What this trial studies
This study evaluates the effectiveness of reSET, an FDA-authorized mobile therapeutic, in treating stimulant use disorder among men who have sex with men living with HIV. The approach focuses on optimizing care and supporting treatment adherence to maintain stable HIV viral load suppression. Participants will receive standard care alongside the reSET intervention, which aims to enhance their treatment outcomes. The study targets individuals who are Aids Healthcare Foundation patients in specific metro areas and screens for stimulant use disorder severity.
Why it matters
Potential benefit: If successful, this study could improve treatment adherence and health outcomes for men living with HIV who also struggle with stimulant use disorder.
How similar studies have gone: Other studies have shown promise in using mobile therapeutics for substance use disorders, indicating potential success for this approach.
