Elevating Lives for More Than 30 Years

For more than three decades, Acadia has been at the forefront of healthcare, elevating lives by providing essential solutions to those who need them most. We pioneered the first and only approved therapies for hallucinations and delusions in Parkinson’s disease psychosis and Rett syndrome. Currently, our clinical-stage developments focus on addressing Prader-Willi syndrome, Alzheimer’s disease psychosis, and neuropsychiatric symptoms in CNS disorders.

Fighting Disease So More “You” Shines Through

At Acadia, we are committed to developing therapies in areas with high unmet needs, elevating life to ensure a brighter future for all. United in our commitment, we strive for a healthier tomorrow—embracing diverse perspectives, fostering collaboration, and standing resilient in our mission to elevate life with unwavering dedication.
