IMSTI Trial Summary

This trial is investigating the effects of reducing methamphetamine use on rectal inflammation, substance use, and HIV/STI risk behavior. It will enroll 40 HIV-negative men who have sex with men, half of whom have rectal gonorrhea/chlamydia infection, and observe them for 8 weeks.

This trial is for cisgender male methamphetamine users aged 18-45 who have had unprotected intercourse with an HIV-positive or unknown status partner in the last 90 days. Participants must be HIV-negative, understand English, and meet criteria for methamphetamine use disorder. Half need a positive test for rectal gonorrhea/chlamydia; the other half negative. Those on treatment for other substance disorders or testing positive for certain drugs are excluded.Check my eligibility
What is being tested?
The study tests if reducing methamphetamine use through Contingency Management affects inflammation in the rectum and lowers risky behaviors related to HIV/STI transmission among men who have sex with men (MSM). It will compare those with and without rectal infections over 8 weeks using behavioral surveys, drug testing, and cytokine level measurements.See study design
What are the potential side effects?
While specific side effects aren't listed here as it's a behavioral intervention rather than a medication, common issues might include stress or anxiety from attempting to reduce drug use or discomfort from providing urine and rectal samples.
