NCT06719908

Brief Summary

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.

Outcome Measures

Primary Outcomes (7)

  • Pharmacokinetic evaluation of AFA-281

    Evaluation of AFA-281 concentrations in the blood over time

    Predose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 4, 5, 6, 7, 8, 12 and 24 hours post dose

  • Evaluation of ethanol levels in the blood

    Measure ethanol concentrations in the blood over time

    Collected at 2, 2.25, 2.5, 2.75, 3, 3.25, 4, 5, 6, 7, 8, 12 and 24 hours post administration

  • Dizziness visual analog scale (VAS) assessment

    Central nervous system test. Visual Analogue Scale for dizziness assessment on a scale 0 to 10. 0 no dizziness and 10 worst

    Collected at predose, 1, 2, 3, 4, 6 and 8 hours post dose

  • Choice Reaction Time (CRT) evaluation

    Central nervous system test. The subject is required to respond to one stimulus, the quicker the better

    Predose and 1, 2, 3, 4, 6 and 8 hours post dose

  • Balance Platform assessment

    Central nervous system test. Balance platform assessment

    Predose and 1, 2, 3, 4, 6 and 8 hours post dose

  • Match to Sample Visual Search (MTS) assessments

    Central nervous system test. Assesses attention and visual searching, with a speed accuracy trade-off. The quicker, the better.

    1, 2, 4 and 8 hours post dose

  • Alertness visual analog scale (AVAS)

    Central nervous system test. Asks a subject to indicate their feelings on a line with a scale from 0 mm on the left to 100 mm on the right. The scale can be used to assess sleepiness and other subjective experiences.

    1, 2, 4 and 8 hours post dose

Secondary Outcomes (6)

  • Clinical chemistry

    Baseline, pre-intervention and in 24 hours after completion of the intervention

  • A complete blood count (CBC) with differential

    Baseline, pre-intervention and in 24 hours after completion of the intervention

  • Heart Rate

    Predose, 1, 2, 4 hours post dose

  • Blood pressure, both systolic, and diastolic pressure

    Predose, 1, 2, 4 hours post dose

  • Body weight

    Baseline, pre-intervention and after in 24 hours of the intervention

  • +1 more secondary outcomes
