Study of DCR-AUD in Healthy Volunteers

Alcohol Use Disorder (AUD) Clinical Trial

Official title: A Phase 1, Double-blind, Placebo-controlled, Single-ascending Dose, Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics Study of DCR-AUD in Healthy Volunteers

Status Completed

Clinical Trial Summary

DCR-AUD will be evaluated for safety, tolerability, pharmacokinetics, and pharmacodynamics in healthy volunteers.

Clinical Trial Description

DCR-AUD is being developed for the treatment of alcohol use disorder (AUD) in adults using an RNA interference (RNAi) technology platform. This is a 24-week, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, PK, and PD of single-ascending doses (SAD) of DCR-AUD administered to adult HVs. The single doses of DCR-AUD will be administered to adult HVs across 4 sequential cohorts (3 planned [80 mg, 240 mg, 480 mg] and one optional [960 mg]). Each cohort will comprise a sentinel group of 3 participants (2 active, 1 placebo) and an expanded group of 6 participants (4 active, 2 placebo). The sentinel group will be followed for the assessment of safety and tolerability and characterization of PK but who will not undergo any EIAs. Participants will receive a single dose of study intervention on Day 1 and will be followed for 24 weeks. Participants who have positive ethanol reaction symptoms at the Day 169 EIA (e.g., nausea, vomiting, or substantial flushing) will return every 28 (±7) days for follow-up EIAs until the positive ethanol reaction symptoms abate. These conditional follow-up (CFU) EIAs will not require overnight admission to the clinic, but all other aspects of the EIA will be conducted (see Table 3). Participants will be observed for not less than 6 hours after ethanol administration and will not be discharged until the Investigator deems it medically safe to do so. ;
