Biobehavioral Interventions for HIV-negative, Stimulant Using Men Who Have Sex With Men

• Status: Completed
• Trial end date: 2013-03-01
• Target enrollment: 0
• Participant gender: Male

Summary

This study seeks to evaluate the efficacy of a contingency management (CM) intervention compared to a yoked control condition for eliminating illicit stimulant use and for decreasing time to initiating post exposure prophylaxis (PEP), for improving adherence to PEP, and for completing PEP following a potential HIV-exposure event. Men who have sex with men who use cocaine amphetamine or methamphetamine frequently also have high risk sexual behaviors during or after their drug use. The objective of this study evaluates whether the use of CM that targets stimulant use significantly aids men who have sex with men who use stimulants and also engage in high-risk sexual transmission behaviors to be able to initiate, adhere to and complete PEP, thereby optimizing the utility of a biomedical HIV prevention intervention for reducing HIV incidence in this very high-risk group of MSM.
