A Multinational, Multi-center, Randomized, Double-blind, Active Comparator, Phase III Clinical Trial to Evaluate the Efficacy and Safety of Donepezil Transdermal Patch in Patients With Alzheimer's Disease
- Registration Number
- NCT03197740
- Lead Sponsor
- Icure Pharmaceutical Inc.
- Brief Summary
The objective of this study is to evaluate the efficacy and safety of donepezil transdermal patch in patients with mild to moderate Alzheimer's disease.
The primary objective is to demonstrate the non-inferiority of the test drug, IPI-301 (donepezil transdermal patch), to the comparator, Aricept tablet, after 24 weeks of treatment in patients with mild to moderate Alzheimer's disease in terms of improvement in cognitive function as assessed by the Alzheimer's Disease Assessment Scale - Cognitive (ADAS-cog) and in terms of global assessment as assessed by Clinician's Interview Based Impression of Change plus Caregiver Input (CIBIC-plus).
