Methamphetamine Disorders

This is a hybrid type I randomized controlled trial to test the effectiveness of contingency management (CM) alone versus CM with motivational interviewing (MI) for optimizing entry or re-entry into the HIV prevention or care continua. A total of 400 participants will be randomized to CM (n = 200) or MI+CM (n = 200), all delivered via telehealth. Monthly follow-up assessments will be completed over 12 months to examine effectiveness MI+CM for the primary outcome - filling a pre-exposure prophylaxis (PrEP) or anti-retroviral therapy (ART) prescription (verified using a digital photo). Secondary outcomes will include: self-reported PrEP or ART clinical evaluation by a provider; self-reported meth and other substance use severity (ASSIST), and self-reported receptive and insertive condomless anal sex (CAS).

PROJECT RESIN: This study is examining the reliability, validity, and acceptability of a novel visual scale for estimating daily methamphetamine use among people who use methamphetamine.

The purpose of the study is to evaluate the safety, efficacy, and pharmacokinetics of four single, increasing doses of CS-1103, given by intravenous (IV) infusion in otherwise healthy, non-treatment seeking participants with methamphetamine use disorder in the presence of a clinically relevant dose of methamphetamine HCl (30 mg IV).
