Abstract

Aim: Determine whether patients with Alzheimer’s disease demonstrating functional and cognitive decline, following 24-48 weeks of open-label treatment with 9.5 mg/24 h (10 cm(2)) rivastigmine patch, benefit from a dose increase in a double-blind (DB) comparative trial of two patch doses.; Methods: Patients meeting prespecified decline criteria were randomized to receive 9.5 or 13.3 mg/24 h (15 cm(2)) patch during a 48-week, DB phase. Coprimary outcomes were change from baseline to week 48 on the Instrumental Activities of Daily Living domain of the Alzheimer’s Disease Cooperative Study-Activities of Daily Living (ADCS-IADL) scale and the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog). Safety and tolerability were assessed.; Results: Of 1,584 patients enrolled, 567 met decline criteria and were randomized. At all timepoints, ADCS-IADL and ADAS-cog scores favoured the 13.3 mg/24 h patch. The 13.3 mg/24 h patch was statistically superior to the 9.5 mg/24 h patch on the ADCS-IADL scale from week 16 (p = 0.025) onwards including week 48 (p = 0.002), and ADAS-cog at week 24 (p = 0.027), but not at week 48 (p = 0.227). No unexpected safety concerns were observed.; Conclusions: The 13.3 mg/24 h rivastigmine patch significantly reduced deterioration in IADL, compared with the 9.5 mg/24 h patch, and was well tolerated.; Copyright © 2012 S.
