Oxytocin HIV Meth Study (OHM)

4. marts 2019 opdateret af: Christopher Stauffer, University of California, San Francisco

The Effects of Intranasal Oxytocin on Mixed HIV Sero-status, Methamphetamine-using Men Who Have Sex With Men

The purpose of this pilot study is to determine the tolerability, feasibility, and preliminary effectiveness of intranasal oxytocin administration prior to motivational enhancement group therapy sessions on laboratory-based measures of addiction, social connectedness, and stress responsivity in methamphetamine(meth)-using men who have sex with men (MSM). The investigators propose a randomized, double-blind, study of intranasal oxytocin versus placebo 40 IU prior to each of six Motivational Interviewing Group Therapy (MIGT) sessions in 28 mixed HIV sero-status MSM initiating treatment for amphetamine use disorder.

Detaljeret beskrivelse

The high prevalence of amphetamine use disorder (AUD) among men who have sex with men (MSM) leads to significant health disparities, including increased risk for HIV sero-conversion. Reducing methamphetamine use mitigates HIV risk. Currently no psychopharmacological agent exists for the treatment of AUD; innovative interventions are desperately needed. Oxytocin, a social neuropeptide, has well-studied anti-addiction effects in animal models of substance dependence. The use of intranasal oxytocin for a variety of human substance use disorders is under early investigation, although no one has studied oxytocin's effects in AUD. In other populations, oxytocin's effects are known to vary depending on social context. Psychosocial treatment alone has been shown to reduce methamphetamine and HIV risk in MSM at a community-based clinic in San Francisco, The Stonewall Project. The investigators propose a randomized, double-blind pilot study of psychopharmacological-psychosocial combination therapy, administration of intranasal oxytocin versus placebo prior to six Motivational Interviewing Group Therapy (MIGT) sessions, in 28 mixed HIV sero-status MSM initiating treatment for AUD. The investigators aim to assess: 1) tolerability, 2) feasibility for larger randomized controlled trials, and 3) exploratory measures of efficacy, including: a) urine levels of methamphetamine and metabolites, b) methamphetamine craving, c) engagement in MIGT through third-party coding of videotaped group sessions and self-reported measures of group connectedness, d) psychophysiological stress responses to group engagement, and e) sexual risk taking.

Foranstaltningsbeskrivelse
Tidsramme
Side effect profile
Tidsramme: 6 weeks

Aim 1: To examine the tolerability of repeated oxytocin dosing in MSM who use meth.

Hypothesis 1: There will be no difference in side effect profiles for those receiving oxytocin (40 IU) versus placebo prior to each of six MIGT sessions, and there will be no study-related adverse events.

Tidsramme
Recruitment Rates
Tidsramme: 6 weeks

Aim 2: To determine the feasibility of implementing a larger randomized controlled trial of oxytocin dosing in meth-using MSM.

Hypothesis 2: This community-based pilot study will recruit and enroll 38 individuals within 6 months and have retention rates ≥75%. The investigators will collect effect size data to be used in planning the sample size of larger clinical trials. The investigators will collect pilot validation data for our exploratory measures and paradigms.

urine toxicology
Tidsramme: 6 weeks
Although efficacy is not the primary aim of this pilot study, following administration of 40 IU intranasal oxytocin compared to placebo prior to six MIGT sessions the investigators expect to see trends toward reduction in meth-positive urine toxicology screens.
6 weeks
Meth Craving Questionnaire-Brief (MCQ-Br)
Tidsramme: 6 weeks
Although efficacy is not the primary aim of this pilot study, following administration of 40 IU intranasal oxytocin compared to placebo prior to six MIGT sessions the investigators expect to see trends toward reduced self-reported meth craving as measured by the MCQ-Br.
6 weeks
attendance rate
Tidsramme: 6 weeks
Although efficacy is not the primary aim of this pilot study, following administration of 40 IU intranasal oxytocin compared to placebo prior to six MIGT sessions the investigators expect to see trends toward improved attendance.

Group Questionnaire
Tidsramme: 6 weeks
Although efficacy is not the primary aim of this pilot study, following administration of 40 IU intranasal oxytocin compared to placebo prior to six MIGT sessions the investigators expect to see trends toward increased therapeutic alliance as measured by the Group Questionnaire.
6 weeks
heart rate variability
Tidsramme: 6 weeks
Although efficacy is not the primary aim of this pilot study, following administration of 40 IU intranasal oxytocin compared to placebo prior to six MIGT sessions the investigators expect to see trends toward increased heart rate variability, a marker of parasympathetic control.
