Official title
Contingency Management for PrEP Adherence and/or Methamphetamine UseDisorder Among MSM and TW in Los Angeles: A Pilot Feasibility Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Use of crystal methamphetamine (MA) leads to changes in sexual risk behavior, adherence to HIV prevention tools, immune response to infection, and tissue inflammation that collectively increase risk for HIV transmission among MA-using men who have sex with men (MSM), their sexual partners, and their networks. Contingency Management (CM) offers a behavioral modification tool helpful for reducing frequency of MA use, but the effects of CM on the behavioral and biological factors that promote HIV transmission in MSM networks have only been partially evaluated. The intersection of substance use, sexual risk behavior, and HIV transmission in MSM networks presents a critical problem for contemporary HIV prevention as HIV-uninfected MSM who use MA have a 16%-33% greater risk for HIV infection, while only approximately 50% of HIV-infected MA-using MSM achieve and maintain an undetectable viral load. The investigators propose to compare two different CM models to integrate substance use treatment with HIV prevention among MA-using MSM: 1) Traditional CM targeted to MA abstinence and 2) Allternative CM based on ARV adherence.
