Background/aims: A large multicenter trial of donepezil 23 mg/day versus donepezil 10 mg/day for moderate-to-severe Alzheimer’s disease allowed patients taking concomitant memantine. We evaluated the efficacy/safety of donepezil 23 and 10 mg/day in this trial, with respect to concomitant memantine use.; Methods: Prespecified analysis of data from a 24-week, randomized, double-blind trial. Patients were randomized […]
Following a 48-week, double-blind, randomized, placebo-controlled trial of donepezil in 821 patients with amnestic mild cognitive impairment (aMCI), safety and tolerability of donepezil (10 mg) were further evaluated in a 28-week extension study. Of 499 participants who completed the double-blind phase, 145 enrolled in the open-label study. Adverse events (AEs) were recorded throughout. Overall, 57.4% […]
Background: Alzheimer’s disease is characterized by the presence of cortical amyloid-beta (Aβ) protein plaques, which result from the sequential action of β-secretase and γ-secretase on amyloid precursor protein. Semagacestat is a small-molecule γ-secretase inhibitor that was developed as a potential treatment for Alzheimer’s disease.; Methods: We conducted a double-blind, placebo-controlled trial in which 1537 patients […]
