Octohydroaminoacridine Succinate Tablet for Mild-to-Moderate Alzheimer's Disease
October 20, 2019 updated by: Shanghai Mental Health Center
Phase III Trial of Octohydroaminoacridine Succinate Tablet for Mild-to-Moderate Alzheimer's Disease: a 26 Weeks, Randomized, Double-blind, Double-dummy, Placebo- and Positive- Parallel Controlled and Extended Single Arm to 54 Weeks Multicentre Study
Inhibition of acetylcholinesterase has been a effective treatment for Alzheimer's disease.
Octohydroaminoacridine, a new acetylcholinesterase inhibitor, is a potential treatment for Alzheimer's disease.
The investigators conducted a 26 weeks, randomized, double-blind, double-dummy, placebo- and positive- parallel controlled and extended single arm to 54 weeks multicentre phase III clinical trial to investigate the effects of octohydroaminoacridine in patients with mild-to-moderate Alzheimer's disease.
Patients were randomized to receive placebo thrice daily, or octohydroaminoacridine 4 mg/TID or ARICEPT 5mg/QD.
