A-HACK Project: Addressing Heavy Alcohol Use Consumption With Kudzu
In Brief
A Phase 2 clinical trial evaluating Standardized kudzu, Placebo, and 6 other interventions for Alcohol Use Disorder and Sexually Transmitted Diseases. Completed, enrolled 120 participants across 1 site.
Detailed Summary
Drinking multiple alcoholic drinks on a single occasion (binge drinking), has many negative health risks but interventions to address this behavior remain limited. This double-blind, placebo-controlled randomized clinical trial will test whether kudzu, an herbal supplement, can reduce heavy alcohol use and alcohol-associated sexual behaviors among sexually-active, binge-drinking individuals at high risk for HIV infection.

Timeline
Interventions
Standardized kudzu
Placebo
At baseline and month 3 visits, all participants will be tested for syphilis (serum RPR), Neisseria gonorrhea and Chlamydia trachomatis (urine, pharyngeal swab, and rectal swab nucleic acid amplification \[NAAT\]) through an established protocol that has been validated by our Public Health Laboratory (PHL) and others.
MM has been used in a targeted pharmacotherapy trial and our team has successfully used MM in AUD trials. 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.
Urine samples will be collected at Enrollment, Month 1, Month 2 and Month 3 visits and tested for ethyl glucuronide (EtG) to determine recent alcohol consumption in the past three days. EtG is a relatively novel, highly sensitive indicator for recent alcohol consumption; this alcohol biomarker is detectable in urine for approximately 72 hours.
DBS samples will be collected at enrollment, weeks 12, and post-treatment visits at month 3. Samples will be dried overnight using standardized methods. PEth testing of DBS samples will be conducted at the United States Drug Testing Laboratories in Des Plaines, IL using liquid chromatography-tandem mass spectrometry system following extraction into methanol.
Standardized and validated behavioral measures will be assessed using audio computer administered surveys (ACASI) to minimize underreporting of risk activities and standardize data collection.To minimize potential social desirability bias, staff will not have access to data during the trial.
Participants will receive daily SMS texts to collect data on alcohol consumption, number of drinks on drinking days, targeted medication administration prior to anticipated drinking sessions, and sexual risk behaviors
