Better Than Study: Targeting Heavy Alcohol Use With Naltrexone Among MSM

University of California, San Francisco·interventional·Posted Jan 5, 2015·Updated Apr 20, 2025

In Brief

A Phase 2 clinical trial evaluating Placebo, Naltrexone, and 5 other interventions for Binge Drinking and HIV. Completed, enrolled 120 participants across 1 site.

Detailed Summary

This is a double-blind, placebo-controlled trial of 120 binge-drinking MSM to 12 weeks of naltrexone 50mg, to be taken in anticipation of heavy drinking. Ethnically and racially diverse participants will be recruited using Respondent Driven Sampling as well as active field recruitment. MSM will be seen weekly for alcohol-metabolite urine testing, study drug dispensing, and brief counseling for alcohol use. Safety assessments and behavioral surveys will be completed monthly.

Interventions

Placebodrug

Placebo capsules will contain microcrystalline cellulose (Medisca). Placebo and active medication will be provided in capsules that are an exact match in color, so as to make the placebo and active medication indistinguishable from each other.

Naltrexonedrug

REVIA is a white, crystalline compound. The hydrochloride salt is soluble in water to the extent of about 100 mg/mL. REVIA is available in scored film-coated tablets containing 50 mg of naltrexone hydrochloride.

Medical Management (MM) counseling for alcohol use:behavioral

MM is a low-intensity supportive program designed to increase problem recognition and enhance motivation to change maladaptive alcohol use patterns. Participants will receive individual 20 minute MM sessions weekly from trained staff supervised by a clinical psychologist

Urinalysis for novel alcohol biochemical markers:other

Urine samples will be collected weekly and tested for ethyl glucuronide (EtG) to determine recent alcohol consumption. EtG is a relatively novel, highly sensitive indicator for recent alcohol consumption; this alcohol biomarker is detectable in urine for approximately 72 hours).

Behavioral survey measurements:behavioral

Standardized and validated behavioral measure that will be assessed using audio computer administered surveys (ACASI) to minimize underreporting of risk activities and standardize data collection

Dried Blood Spot (DSB) Testing for Phosphatidylethanolother

Phosphatidylethanol (PEth)-a phospholipid formed only in the presence of alcohol-is a novel, direct biochemical marker of alcohol that has shown high (\>95%) sensitivity and specificity to detect heavy drinking over a period of 2-3 weeks in several studies of dependent patients and abstainers. DSB samples will be collected at enrollment, weeks 3, 6, 9, 12, and post-treatment visits at month 1, 3, and 6.

Ecological Momentary Assessmentbehavioral

Ecological Momentary Assessments are SMS texts to collect data on alcohol consumption, number of drinks on drinking days, and targeted medication administration prior to anticipated drinking sessions. Messages will use short-hand notations to maintain participant confidentiality
