A Study to Evaluate the Safety/Tolerability, Pharmacokinetics, and Pharmacodynamics of Oral AD-6626 in Normal, Healthy Volunteers and Subjects Heterozygous for the Aldehyde Dehydrogenase 21/2 Genetic Variant With and Without Alcohol Administration

A Single-Center, 2-Part, Randomized, Double-Blind, Placebo-Controlled, Single-dose, Dose Escalation Study to Evaluate the Safety/Tolerability and Pharmacokinetics of a Single Dose of AD-6626 Administered Orally to Normal, Healthy Volunteers in Part A and the Safety/Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of a Single Oral Dose of AD-6626 Followed by Alcohol Administration in Normal, Healthy Volunteers With the Aldehyde Dehydrogenase 2 (ALDH2)*1/*1 (Wild Type) or ALDH2*1/*2 (Heterozygous) Genetic Variant in Part B

Brief summary

The primary purpose of this study on healthy volunteers is to determine the safety and tolerability of oral AD-6626 without and without alcohol administration in normal healthy volunteers and subjects heterozygous (HeZ) for the aldehyde dehydrogenase 2 (ALDH2)*1/*2 genetic variant

Interventions

Part A consists of sequential dose escalation with approximately 5 cohorts of subjects (8 subjects per cohort) given a single oral dose of AD-6626 or placebo. The doses of AD-6626 are 100mg, 300mg, 600mg, 1200mg and 1200mg with food. Part B is a two period crossover of single oral administration of AD-6626 or placebo following oral EtOH administration in NHVs or subjects with the ALDH2*1/*2 (HeZ) genotype. A total of 24 subjects will be dosed. The dose of AD-6626 will be determined from Part A of the study. The oral EtOH dose will be 0.75 gm/kg for NHVs and 0.5 gm/kg for subjects with the ALDH2*1/*2 genotype. The AD-6626 will be given 30 minutes before the oral dose of EtOH. There will be 7 days between the treatments in Part B

Inclusion criteria

This study will be conducted in normal, healthy, adult, male or female aged between 21-45 years and with a BMI greater than or equal to 18 and less than or equal to 30. Eligible subjects will be in good health without signs or symptoms of current illness and with predose clinical and laboratory examinations without clinically significant findings. Subjects in Part A will be of non-Asian descent. Subjects in Part B will be of Asian or non-Asian descent with ALDH2*1/*2 (HeZ) or ALDH2*1/*1 (WT) genotype, respectively

Exclusion criteria

- Homozygous for the ALDH2*2/*2 genotype - History of clinically significant endocrine, neurological, gastrointestinal, cardiovascular, hematological, hepatic, immunological, renal, respiratory, or genitourinary abnormalities or diseases - History of severe allergic or anaphylactic reactions - Fever (body temperature >38 degrees celsius) or symptomatic viral or bacterial infection within 2 weeks prior to Screening - Blood pressure (BP) >140/90 mm Hg or a heart rate (HR) >100 beats per minute at Screening and at Day -1 - Clinically significant laboratory abnormalities - Female who is breastfeeding or has a positive pregnancy test at any visit
