About this study
Official title: A Double-blind, Placebo-controlled, Phase I Study of the Pharmacokinetic and Pharmacodynamic Interaction of Oral AFA-281 With Alcohol in Healthy Volunteers
The goal of this clinical trial is to evaluate if alcohol interacts with the drug candidate AFA-281 in adults (healthy volunteers). This trial will evaluate blood concentration levels of AFA-281 and ethanol. The main questions it aims to answer are: Does alcohol interact with AFA-281? What are the side effects (if any)? Researchers will compare AFA-281 to a placebo (a look-alike substance that contains no drug) to see if AFA-281 interacts with alcohol.
Participants will take a total of 4 treatment sessions separated by at least 2 days between treatments. The treatments will incorporate AFA-281 or placebo with ethanol or ethanol placebo. After each treatment vital signs will be monitored and blood collected to measure AFA-281 and ethanol levels. Participants will provide an assessment survey of symptoms. The total treatment time will be 9 inpatient days (8 nights), and a final follow-up visit 3 to 5 days after clinic discharge.
Read the detailed description
This is a randomized, double-blind, placebo-controlled, 4-way crossover study of the interaction of alcohol and oral AFA-281 in healthy adult volunteers. This study will evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) effects of co-administration of AFA-281 and ethanol in healthy, male and female subjects who are social or moderate drinkers but do not meet criteria for the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis of Alcohol Use Disorder. Each subject will receive single doses of AFA-281, ethanol, placebo for AFA-481, and placebo for ethanol in a randomized, double-blind, crossover manner. Randomized blocks will be included to ensure that there is 1 day in between treatment sessions. Blood will be collected for PK and blood alcohol levels at pre-dose and at multiple timepoints after treatment. Safety parameters will be evaluated for tolerability such as vital signs and clinical pathology. Participants will provide an assessment survey of symptoms. The total treatment time will be 9 inpatient days (8 nights), and a final follow-up visit 3 to 5 days after clinic discharge.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AFA-281 is a small molecule, orally available and Alcohol (Ethanol) in people with Alcohol and Alcohol Use Disorders, run by Afasci Inc.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 6 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Simon Xie, MD (650-995-7320, simonxie@afasci.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pharmacokinetic evaluation of AFA-281 (time frame: Predose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 4, 5, 6, 7, 8, 12 and 24 hours post dose). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2024; AzTrials last refreshed its copy on 7 Nov 2026.
