Turning Scientific Promise into Meaningful Innovation

At Acadia, our mission is to turn scientific promise into meaningful innovation that makes the difference for underserved neurological disorders and rare disease communities around the world. Currently, our clinical-stage developments focus on addressing Alzheimer’s disease psychosis and Lewy body dementia psychosis, along with early-stage programs that address other unmet patient needs. We are working to seek approval of our treatment option for people living with Rett syndrome in Europe.

We have submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for our treatment of Rett syndrome.

Our Focus

Our clinical-stage development efforts are focused on Alzheimer’s disease psychosis and multiple other programmes targeting neuropsychiatric symptoms in central nervous system disorders.
