title: Mayo Acute Stroke Trial for Enhancing Recovery (MASTER) protocol.
abstract: BACKGROUND
  Stroke is the leading cause of acquired disability in adulthood. Ischemic stroke often results in physical, emotional, and cognitive impairment. There is no definitively proven pharmacologic technique to accelerate recovery from stroke. The short-term goal of this study is to develop donepezil hydrochloride as pharmacotherapy for enhancing stroke recovery.
  
  
  METHODS
  The Mayo Acute Stroke Trial for Enhancing Recovery (MASTER) is a prospective, stratified 2-stage trial of donepezil for acute ischemic stroke. Suitable patients must receive treatment within 24 hours of developing symptoms. A total of 30 to 40 patients will be enrolled. TRIAL PROCEDURES: Participants will receive up to 10 mg of donepezil daily for 90 days. Patients will be assessed at less than 24 hours (pretreatment), 30 days, 60 days, 90 days, and 6 months off-drug poststroke. Assessments will include examinations of neurologic, cognitive, functional, and psychological status. The primary outcome will be excellent neurologic recovery, defined as National Institutes of Health Stroke Scale score of 0 or 1 at 90 days after stroke. Secondary outcome measures are the proportion of patients with favorable outcomes defined as follows: National Institutes of Health Stroke Scale score of 0 or 1 at 6 months; modified Rankin scale score of 0 or 1 at 90 days and 6 months; modified Rankin scale score less than 3 at 90 days and 6 months; and Mini-Mental State Examination score greater than 24 at 90 days and 6 months.
