Phase 3
Completed
Conditions
Early AD (Mild cognitive impairment due to AD and Mild AD dementia)
Registration Number
JPRN-jRCT2080223496
Lead Sponsor
Eisai Co., Ltd.
Brief Summary

This study was terminated early due to an unfavorable risk-benefit ratio including no evidence of potential efficacy and the adverse event profile in subjects with drug treatment was worse than that in subjects who received placebo. The small sample size at the 24 month time point of the Core Study limits the interpretability of the data.
