This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
In this study, "PrEP Intervention for people who Inject Substances and Use Methamphetamine" (PRIME), we propose to assess if using video directly observed therapy with real-time contingency management (VDOT-CM) may help people assigned male sex at birth who inject methamphetamine adhere to PrEP. We will randomize 140 adults who use methamphetamine, are HIV-negative, and have recently engaged in a sexual HIV risk behavior to VDOT-CM or counseling alone for 24 weeks. The study aims are to (1) determine the efficacy of VDOT-CM compared to counseling alone for PrEP adherence, (2) evaluate the acceptability of PrEP and adherence support strategies among the cohort, and (3) compare injection or chemsex and sexual HIV risk behavior before and during PrEP use. We hypothesize that participants randomized to VDOT-CM will have superior adherence to PrEP. We also hypothesize that participants will describe barriers to and facilitators of PrEP adherence, and those who are randomized to VDOT-CM will consider it an acceptable PrEP adherence support strategy. Finally, we do not expect to find increased injection, chemsex, or sexual risk behaviors for HIV among study participants after they begin taking PrEP.
PrEP Intervention for People Who Inject Substances and Use Methamphetamine
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
