The Combination of Donepezil and Cognitive Training for Treating Alcohol Use Disorder

Phase 2

Completed

• Conditions: Alcohol Use Disorder; Mild Cognitive Impairment
• Interventions: Combination Product: Donepazil

• Registration Number: NCT04318639
• Lead Sponsor: VA Connecticut Healthcare System

Brief Summary

This is an open label feasibility trial to learn whether the combination of donepezil and cognitive remediation therapy (Donepezil + CRT) may improve neurocognitive functioning and decreasing alcohol use in Veterans with alcohol use disorder who have mild cognitive impairment (AUD-MCI). The study will determine the acceptability and adherence to treatment and preliminary evidence for efficacy. The study will recruit 15 newly recovering Veterans individuals with AUD-MCI for a 13-week, open-label, single-arm pilot study with sobriety and cognitive assessments at baseline and at 13-week follow-up.

Detailed Description

Donepezil is FDA approved for treatment of dementia and recent animal studies have suggested that it may reduce craving in rat models of alcohol use disorder. Investigators' previous studies of cognitive remediation therapy (CRT) with work therapy have shown efficacy with newly recovering Veterans with AUD compared with work therapy alone. The current study combines Donepezil and CRT in an open-label trial to learn whether the combination of Donepezil + CRT may improve neurocognitive functioning and decrease alcohol use in Veterans with alcohol use disorder who have mild cognitive impairment (AUD-MCI). The study will determine the acceptability and adherence to treatment and provide preliminary evidence for efficacy. The study will recruit 15 newly recovering Veterans individuals with AUD-MCI for a 13-week, open-label, single-arm pilot study with sobriety and cognitive assessments at baseline and at 13-week follow-up. Primary outcome variables will be a Clinical Global Index of AUD recovery and a Global Cognitive Composite of MCI related neurocognitive assessment.
