About Acadia

Be Their Difference

Driven by the needs of underserved communities, we combine bold science with real-world insights to bring forward therapies others may overlook. Addressing complex neurological disorders and rare diseases requires more than treatments alone; it also means delivering meaningful innovation alongside the resources, tools, and support that empower patients, caregivers, and families to experience lasting improvements in their daily lives. This commitment is reflected in our values: Start with them, Listen to learn, See the promise, and Make it happen.

Leading Innovative Treatments

We developed and commercialised a treatment option for patients with hallucinations and delusions associated with Parkinson's disease psychosis in the United States, as well as another treatment option for patients with Rett syndrome in the United States and Canada. We are working to seek approval of our treatment option for people living with Rett syndrome in Europe.

Developing Therapies for Unmet Needs

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

Join Our Team

We are seeking individuals with diverse skills, experiences, and backgrounds to join our growing team. Headquartered in San Diego, California, with a presence across Europe, the United States, and Canada, we are building a world-class organisation dedicated to working to improve the standard of care in neuroscience and rare disease.
