Objective: To evaluate safety and efficacy of a donepezil patch 27.5\u200amg application for 52 weeks in patients with mild-to-moderate Alzheimer\u2019s disease; and to evaluate safety on switching from donepezil hydrochloride tablets. Methods: This 28-week, open-label study (jRCT2080224517) is an extension of a 24-week double-blind (donepezil patch 27.5\u200amg versus donepezil hydrochloride tablet\u00a05\u200amg) noninferiority study. The patch group (continuation group) continued administration of the patch and the tablet group (switch group) switched to the patch in this study. Results: A total of 301 patients participated (156 patients continued using patches; 145 patients switched). Both groups showed similar course on the Alzheimer\u2019s Disease Assessment Scale-cognitive component-Japanese version (ADAS-Jcog) and ABC dementia scales. At weeks 36 and 52, changes in ADAS-Jcog from week 24 [mean (standard deviation)] were 1.4 (4.8) and 2.1 (4.9) in the continuation group, and 1.0 (4.2), and 1.6 (5.4) in the switch group. The incidence of adverse events at application site in the continuation group over 52 weeks was 56.6% (98\/173). Erythema, pruritus, and contact dermatitis at application site were observed in more than 10 patients each. There was no additional adverse event of clinical concern, and no increase in their incidence from the double-blind study. During the four weeks following switching, no patient discontinued or suspended administration due to adverse events. Conclusion: Application of the patch for 52 weeks was well tolerated and feasible, including switching from tablets.<\/jats:p>","DOI":"10.3233\/jad-230387","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T10:53:29Z","timestamp":1686912809000},"page":"685-693","source":"Crossref","is-referenced-by-count":1,"title":["Efficacy and Safety of a Transdermal Donepezil Patch in Patients with Mild to Moderate Alzheimer\u2019s Disease: Open-Label, Extension Study"],"prefix":"10.1177","volume":"94","author":[{"given":"Yu","family":"Nakamura","sequence":"first","affiliation":[{"name":"Department of Neuropsychiatry, Faculty of Medicine, Kagawa University, Kita-gun, Japan"},{"name":"Translational Research Center for Medical Innovation, Foundation for Biomedical Research and Innovation at Kobe, Kobe, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takumi","family":"Omori","sequence":"additional","affiliation":[{"name":"Teikoku Seiyaku, Clinical Development Department, Higashikagawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rei","family":"Kim","sequence":"additional","affiliation":[{"name":"Teikoku Seiyaku, Clinical Development Department, Higashikagawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Nishiyama","sequence":"additional","affiliation":[{"name":"Teikoku Seiyaku, Clinical Development Department, Higashikagawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Kikuchi","sequence":"additional","affiliation":[{"name":"Translational Research Center for Medical Innovation, Foundation for Biomedical Research and Innovation at Kobe, Kobe, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ichiro","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Department of Neuropsychiatry, Faculty of Medicine, Kagawa University, Kita-gun, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Aoki","sequence":"additional","affiliation":[{"name":"Teikoku Seiyaku, Clinical Development Department, Higashikagawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/JAD-230387_ref1","doi-asserted-by":"crossref","first-page":"136","DOI":"10.1212\/WNL.50.1.136","article-title":"A 24-week, double-blind, placebo-controlled trial of donepezil in patients with Alzheimer\u2019s disease","volume":"50","author":"Rogers","year":"1998","journal-title":"Neurology"},{"key":"10.3233\/JAD-230387_ref2","first-page":"361","article-title":"Transdermal donepezil on the treatment of Alzheimer\u2019s disease","volume":"8","author":"Sozio","year":"2012","journal-title":"Neuropsychiatr Dis Treat"},{"key":"10.3233\/JAD-230387_ref3","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1111\/ggi.14566","article-title":"Efficacy and safety of a transdermal donepezil patch in patients with mild-to-moderate Alzheimer\u2019s disease: A 24-week, randomized, multicenter, double-blind, parallel group, non-inferiority study","volume":"23","author":"Nakamura","year":"2023","journal-title":"Geriatr Gerontol Int"},{"key":"10.3233\/JAD-230387_ref4","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2013) Diagnostic and Statistical Manual of Mental Disorders, 5th edn.
