Assessing the Safety and Efficacy of FSD-F2R6-A-CP in Volunteers in an Induced State of Alcohol Intoxication
METAL-2
A Randomized, Double-Blind, Placebo-Controlled Crossover Study to Assess the Safety and Efficacy of FSD-F2R6-A-CP in Volunteers in an Induced State of Alcohol Intoxication (METAL-2)
This will be a (2 visit) double-blind, randomized, placebo crossover design clinical study to assess the potential benefits of FSD-F2R6-A-CP versus a placebo by assessing its impact on side effect profiles as well as cognitive abilities, motor abilities, and breath alcohol concentration following ingestion of alcohol followed by the dietary supplement or placebo. This study will enroll healthy men and women.

Study Timeline
Dates and qualifiers reported by the registry. Estimated dates do not confirm that a milestone has occurred.
Intoxication will be measured using a 0-100 mm VAS scale, with left (0 mm) and right (100 mm) anchors designated 'not at all' and 'very much' to assess subjects' subjective experience of intoxication.
Change in pre-treatment score to 0.5, 1, 2 and 4 hours post-treatment
Impairment
Impairment will be measured using a 0-100 mm VAS scale, with left (0 mm) and right (100 mm) anchors designated 'not at all' and 'very much' to assess subjects' subjective experience of impairment.
Change in pre-treatment score to 0.5, 1, 2 and 4 hours post-treatment
Mental Fatigue
Mental fatigue will be measured using a 0-100 mm VAS scale, with left (0 mm) and right (100 mm) anchors designated 'not at all' and 'very much' to assess subjects' subjective experience of mental fatigue.
Change in pre-treatment score to 0.5, 1, 2 and4 hours post-treatment
Clearheaded-Muzzy
Clearheaded-Muzzy will be measured by a 100 mm visual analog scale (VAS) representing bipolar adjective pairs for the assessment of both alerting and sedating CNS drug effects.
Change in pre-treatment score to 0.5, 1, 2 and 4 hours post-treatment
Clumsy-Well Coordinated
Clumsy-Well Coordinated will be measured by a 100 mm visual analog scale (VAS) representing bipolar adjective pairs for the assessment of both alerting and sedating CNS drug effects.
Change in pre-treatment score to 0.5, 1, 2 and 4 hours post-treatment
Energetic-Lethargic
Energetic-Lethargic will be measured by a 100 mm visual analog scale (VAS) representing bipolar adjective pairs for the assessment of both alerting and sedating CNS drug effects.
Change in pre-treatment score to 0.5, 1, 2 an 4 hours post-treatment
Drowsy-Alert
Drowsy-Alert will be measured by a 100 mm visual analog scale (VAS) representing bipolar adjective pairs for the assessment of both alerting and sedating CNS drug effects.
Change in pre-treatment score to 0.5, 1, 2 an 4 hours post-treatment
Mentally Slow-Quick Witted
Mentally Slow-Quick Witted will be measured by a 100 mm visual analog scale (VAS) representing bipolar adjective pairs for the assessment of both alerting and sedating CNS drug effects.
Change in pre-treatment score to 0.5, 1, 2 and 4 hours post-treatment
Headache
Headache will be measured on a 100 mm VAS. The subject will indicate the severity of any headache by drawing a vertical line on the horizontally positioned VAS. The left end (0 mm) of the VAS will designate 'no pain' and the right end (100mm) will designate 'most severe pain imaginable' with no intermediate divisions or descriptive terms.
Change in pre-treatment score to 0.5, 1, 2, 4 and 8 hours post-treatment
