Stock Update (NASDAQ:ACAD): ACADIA Pharmaceuticals Inc. Announces Positive Top-Line Results From Phase II Study of Pimavanserin for Alzheimer’s Disease Psychosis

ACADIA Pharmaceuticals Inc. (NASDAQ:ACAD) announced positive top-line results from its Phase II exploratory study (-019 Study) of pimavanserin in patients with Alzheimer’s disease psychosis (AD Psychosis). As a selective serotonin inverse agonist (SSIA) preferentially targeting 5-HT2A receptors, pimavanserin has a different biological mechanism than other marketed antipsychotics.

Pimavanserin has been approved by the United States Food and Drug Administration (FDA) for hallucinations and delusions associated with Parkinson’s disease psychosis and currently is being studied in several other disease states, including AD Psychosis. The FDA has not approved any drug to treat AD Psychosis.

In this Phase II exploratory study, pimavanserin met the primary endpoint showing a statistically significant reduction in psychosis versus placebo as measured by the Neuropsychiatric Inventory-Nursing Home (NPI-NH) Psychosis score at week 6 of dosing (p=0.0451). Pimavanserin was generally well tolerated and the safety profile was consistent with what has been observed in previous studies.

“Alzheimer’s disease patients suffer from a number of debilitating symptoms, of which psychosis carries a poor prognosis and is associated with earlier placement into nursing homes,” said Steve Davis, ACADIA’s President and Chief Executive Officer. “Data from the -019 Study provide solid evidence that pimavanserin can improve psychosis in another major neurological disorder and provide strategic momentum for the further development of pimavanserin to address the needs of AD Psychosis patients.” (Original Source)
