  • Initiation, adherence and completion of Post-exposure Prophylaxis. [ Time Frame: 6-month follow-up ] [ Designated as safety issue: Yes ]
    Initiation is defined as starting Post-exposure Prophylaxis at any point after randomization to Contingency Management Condition (active, yoked control); Adherence is self-report and pill count of PEP medications; Completion is completion of the 28 day medication regimen, if started.
  • Abstinence from stimulant drug use (cocaine, amphetamine, methamphetamine) [ Time Frame: 6-month follow-up ] [ Designated as safety issue: Yes ]
    Abstinence will be measured using thrice weekly urine drug screens and self-report
  • Initiation, adherence and completion of Post-exposure Prophylaxis. [ Time Frame: Baseline, 3-month, 6-month ] [ Designated as safety issue: Yes ]
    Initiation is defined as starting Post-exposure Prophylaxis at any point after randomization to Contingency Management Condition (active, yoked control); Adherence is self-report and pill count of PEP medications; Completion is completion of the 28 day medication regimen, if started.
  • Abstinence from stimulant drug use (cocaine, amphetamine, methamphetamine) [ Time Frame: end of treatment, 3- and 6-month follow-up ] [ Designated as safety issue: Yes ]
    Abstinence will be measured using thrice weekly urine drug screens and self-report

Biobehavioral Interventions for HIV-negative, Stimulant Using Men Who Have Sex With Men
Optimizing Access to Non-occupational Post Exposure Prophylaxis for HIV Using Contingency Management in Stimulant-Using Men Who Have Sex With Men

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.

Interventional
Phase 2
Allocation: Randomized
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
  • Stimulant-Related Disorders
  • HIV
  • HIV Infections
Drug: Truvada
Truvada At qualifying exposure, participants will take 28 days' worth (at one pill per day) of 200 mg emtricitabine and 300 mg tenofovir DF (Truvada).
  • Experimental: Contingency Management
    Participants will submit a urine sample every Monday, Wednesday, and Friday for 8 weeks (a total of 24 urine samples). Samples will be tested for stimulant metabolites. Increasingly valuable incentives will be provided for urine samples that lack metabolites of stimulant drugs.
    Intervention: Drug: Truvada
  • Sham Comparator: Yoked Contingency Management
    Participants will submit a urine sample every Monday, Wednesday, and Friday for 8 weeks (a total of 24 urine samples). Samples will be tested for stimulant metabolites. Incentives will be provided to participants independent of stimulant drug use and determined in the same rate and timing as a randomly selected participant in the active CM condition.
    Intervention: Drug: Truvada
