(Nasdaq: ACAD) today announced that the presentation of the results from the Phase 3 HARMONY study of pimavanserin in dementia-related psychosis has been accepted for a late-breaking oral communication at the upcoming 12th Clinical Trials on Alzheimer’s Disease (CTAD) Meeting, December 4-7, 2019 in San Diego, California.\n\n\nLate-Breaking Oral Presentation\n\n\n\nPresentation: LB1\n\n\nAbstract Title: HARMONY Relapse-Prevention Study: Pimavanserin Significantly Prolongs Time to Relapse of Dementia-Related Psychosis\n\n\nPresentation Date: Wednesday, December 4, 2019\n\n\nPresentation Time: 5:45 p.m. Pacific Time\n\n\n\nOn September 9, 2019, ACADIA announced that the Phase 3 HARMONY study, a double-blind, placebo-controlled relapse prevention trial evaluating an investigational use of pimavanserin for the treatment of dementia-related psychosis, met its primary endpoint.
