Prazosin for Disruptive Agitation in Alzheimer's Disease (PEACE-AD) is a Phase IIb multicenter, randomized, double-blind, placebo-controlled trial of 12-weeks treatment with the brain active alpha-1 adrenoreceptor (AR) antagonist prazosin for disruptive agitation in approximately 186 Alzheimer's disease (AD) residents in a long-term care (LTC) setting or living at home with full-time caregiving. Distruptive agitation defined as having one or more of the following behaviors nearly daily during the previous week and at least intermittently for four weeks prior to screening: a) irritability, b) physically and/or verbally aggressive behavior, c) physically resistive to necessary care, d) and/or pressured motor activity (e.g., pressured pacing). LTC is defined as assisted living or skilled nursing facility. Home dwelling participants require full-time caregiving defined as having continuous daily caregiving and a Study Partner who will assist in providing protocol specific information to the study team. A previous single site pilot study addressing disruptive agitation in 22 predominantly LTC-residing AD participants demonstrated efficacy of prazosin on all three primary outcome measures.1 The current multicenter study is funded by the National Institute on Aging (NIA), and coordinated through the NIA-funded Alzheimer's Disease Cooperative Study (ADCS).
