Study to Evaluate AD04 in Adults With Alcohol Use Disorder (AUD) and Selected Serotonin Transporter Polymorphisms

2019-09-27 06:30:39 | BioPortfolio


Randomized, multi-center, double-blind, parallel-group, placebo-controlled study. Eligible subjects will be randomized to receive either 0.33 mg AD04 or placebo orally twice-daily for 24 weeks in conjunction with brief psychological counseling. Randomization will be stratified by gender and level of alcohol consumption prior to enrollment in the study


Target enrollment of subjects with AUD who regularly engage in risk alcohol consumption (i.e. >6/day or more heavy alcohol consumption in the 4 weeks preceding the screening visit), and have selected genotypes (LL/TT genotype and/or 1, 2 or 3 of the SNPs on the genes for the 5-HT3 receptor subunits: rs1150226-AG or rs1176713-GG in the gene that encodes the 5-HT3A receptor subunit, and rs17614942-AC in the gene that encodes the 5-HT3B receptor subunit), and who are eligible to participate in the study based on meeting the remaining study inclusion/exclusion criteria. Eligible subjects will be randomized to receive either 0.33 mg AD04 or placebo BID for 24 weeks.

The trial will have a 16-week grace period to enable medication effects to be optimal for comparison with placebo. The grace period starts immediately after beginning of study drug treatment, in which consumption of alcohol is not counted as a failure. All primary and secondary efficacy endpoints will be assessed during the last 8 weeks of treatment (i.e. weeks 17-24). The primary measure of efficacy, incidence risk alcohol consumption, will be assessed over the last 8 weeks of treatment. To enhance study feasibility, subjects will be evaluated every week during the first 8 weeks of treatment and every other week for the remaining 16 weeks of the treatment period.

Medical and Biotech [MESH] Definitions

Laboratory testing and diagnostic imaging services offered to consumers outside of the patient-physician relationship.

Assessments aimed at determining agreement in diagnostic test results among laboratories. Identical survey samples are distributed to participating laboratories, with results stratified according to testing methodologies.

Allows patient diagnoses in the physician’s office, in other ambulatory setting or at bedside. The results of care are timely, and allow rapid treatment to the patient. (from NIH Fact Sheet Point-of-Care Diagnostic Testing, 2010.)

The process of gaining approval by a government regulatory agency for DIAGNOSTIC REAGENTS AND TEST KITS. This includes any required preclinical or clinical testing, review, submission, and evaluation of the applications and test results, and post-marketing surveillance.

Procedures, such as TISSUE CULTURE TECHNIQUES; mathematical models; etc., when used or advocated for use in place of the use of animals in research or diagnostic laboratories.
