SAN DIEGO--(BUSINESS WIRE)--

ACADIA Pharmaceuticals Inc. (ACAD) today announced FDA approval of a new capsule dose formulation and a new tablet strength of NUPLAZID (pimavanserin) to help in the treatment of patients living with hallucinations and delusions associated with Parkinson’s disease psychosis.

The FDA approval of a 34 mg NUPLAZID capsule formulation will provide patients with the recommended 34 mg once daily dose in a single, small capsule, reducing patient pill burden versus the current administration of two 17 mg tablets. In addition, the FDA approval of a 10 mg tablet provides an optimized lower dosage strength in those patients who are concomitantly receiving strong cytochrome 3A4 inhibitors which can inhibit the metabolism of NUPLAZID.

“We are very pleased with the FDA approval of the NUPLAZID 34 mg capsule and 10 mg tablet, underscoring ACADIA’s continued dedication to advancing safe and effective treatment options for patients living with hallucinations and delusions associated with Parkinson’s disease psychosis,” said Steve Davis, ACADIA’s President and Chief Executive Officer.

“NUPLAZID is a significant advance in our treatments for the hallucinations and delusions in Parkinson's disease,” said Dr. Joseph H. Friedman, Butler Hospital and Warren Alpert Medical School of Brown University. “The replacement of two 17 mg tablets with a single 34 mg capsule provides a simpler and more straightforward approach for the 34 mg once daily NUPLAZID dosing regimen, while also reducing the overall pill burden for my Parkinson’s disease patients who often also take multiple other medications concomitantly.”

The NUPLAZID 34 mg capsules and 10 mg tablets will be available by mid-August.

Important Safety Information and Indication for NUPLAZID (pimavanserin)

WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. NUPLAZID is not approved for the treatment of patients with dementia-related psychosis unrelated to the hallucinations and delusions associated with Parkinson’s disease psychosis.

NUPLAZID is an atypical antipsychotic indicated for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis.

Contraindication: NUPLAZID is contraindicated in patients with a history of a hypersensitivity reaction to pimavanserin or any of its components. Rash, urticaria, and reactions consistent with angioedema (e.g., tongue swelling, circumoral edema, throat tightness, and dyspnea) have been reported.

QT Interval Prolongation: NUPLAZID prolongs the QT interval. The use of NUPLAZID should be avoided in patients with known QT prolongation or in combination with other drugs known to prolong QT interval including Class 1A antiarrhythmics or Class 3 antiarrhythmics, certain antipsychotic medications, and certain antibiotics. NUPLAZID should also be avoided in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes and/or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and presence of congenital prolongation of the QT interval.

Adverse Reactions: The most common adverse reactions (≥2% for NUPLAZID and greater than placebo) were peripheral edema (7% vs 2%), nausea (7% vs 4%), confusional state (6% vs 3%), hallucination (5% vs 3%), constipation (4% vs 3%), and gait disturbance (2% vs <1%).

Drug Interactions: Coadministration with strong CYP3A4 inhibitors (e.g., ketoconazole) increases NUPLAZID exposure. Reduce NUPLAZID dose to 10 mg taken orally as one tablet once daily. Coadministration with strong CYP3A4 inducers may reduce NUPLAZID exposure. Monitor patients for reduced efficacy and an increase in NUPLAZID dosage may be needed.

Pediatric Use: Safety and efficacy have not been established in pediatric patients.

Dosage and Administration: Recommended dose: 34 mg taken orally once daily, without titration.
