SAN DIEGO--(BUSINESS WIRE)--

ACADIA Pharmaceuticals Inc. (ACAD), a biopharmaceutical company focused on the development and commercialization of innovative medicines to address unmet medical needs in central nervous system (CNS) disorders, today announced that the U.S. Food and Drug Administration (FDA) has approved NUPLAZID (pimavanserin) for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis. In 2014, the FDA designated NUPLAZID as a Breakthrough Therapy for this condition.

“Today’s approval of NUPLAZID represents a major paradigm shift in the treatment of Parkinson’s disease psychosis,” said Michael S. Okun, M.D., Medical Director of The National Parkinson Foundation. “Through its novel and selective mechanism of action, NUPLAZID is a breakthrough treatment that works in a whole new way - treating hallucinations and delusions without blocking dopamine receptors and, therefore, not impairing motor function in Parkinson’s psychosis patients.”

NUPLAZID is the first and only medicine to be approved by the FDA for this indication. NUPLAZID is also the only drug approved by the FDA that preferentially targets 5-HT_2A receptors. These receptors are thought to play an important role in Parkinson’s disease psychosis. The unique pharmacology of NUPLAZID establishes a new class of drug - selective serotonin inverse agonists (SSIA) - by not only preferentially targeting 5-HT_2A receptors but also avoiding activity at dopamine and other receptors commonly targeted by antipsychotics. Typical Parkinson’s disease therapy consists of drugs that stimulate dopamine to treat patients’ motor symptoms such as tremor, muscle rigidity and difficulty with walking. NUPLAZID does not interfere with patients’ dopaminergic therapy and therefore does not impair their motor function.

According to the National Parkinson Foundation, about one million people in the United States and from four to six million people worldwide suffer from Parkinson’s disease. An estimated 40 percent of these patients have Parkinson’s disease psychosis, which is characterized by hallucinations and delusions, is associated with significant caregiver burden, and is a major reason for nursing home placement among Parkinson’s patients.

“NUPLAZID represents a major medical advancement for patients with Parkinson’s disease psychosis who suffer from hallucinations and delusions,” said Steve Davis, ACADIA’s President and Chief Executive Officer. “We are grateful to the many patients and investigators who participated in NUPLAZID’s clinical studies. NUPLAZID represents the culmination of many years of work across our entire organization to bring this novel medicine, discovered by our scientists, to patients in need.”

“Parkinson’s disease psychosis is a debilitating condition that adds a tremendous burden on the lives of patients already contending with motor issues such as slow movement, loss of balance, and muscle rigidity,” said Todd Sherer, Ph.D., Chief Executive Officer of the Michael J. Fox Foundation. “It also places an increased burden on caregivers and can lead to loss of independence and nursing home admittance for patients. A therapy to treat the hallucinations and delusions associated with Parkinson’s disease psychosis without worsening motor symptoms can significantly impact the lives of Parkinson’s patients and their loved ones.”

Clinical Data

The FDA approval of NUPLAZID was based on data from the pivotal Phase III Study -020 and other supportive studies, representing the largest research and development program in Parkinson’s disease psychosis to date. In Study -020, NUPLAZID significantly reduced the frequency and severity of psychotic symptoms compared to placebo on the Scale for Assessment of Positive Symptoms – Parkinson’s Disease (SAPS-PD). This benefit was achieved without impairing motor function. The most common adverse reactions (=5% and twice the rate of placebo) in this study were peripheral edema (7% NUPLAZID vs 3% placebo) and confusional state (6% NUPLAZID vs 3% placebo). Results of Study -020 were published in The Lancet. Please see full prescribing information at www.nuplazid.com.

Introducing NUPLAZIDconnect™ Patient Access and Support Services

ACADIA plans to make NUPLAZID commercially available to patients suffering from hallucinations and delusions associated with Parkinson’s disease psychosis in the United States in June 2016. ACADIA is committed to ensuring that patients in the United States who are prescribed NUPLAZID are able to access the medicine and receive the ongoing support they may need. ACADIA will be introducing NUPLAZIDconnect, a comprehensive program that provides financial assistance and/or access assistance to patients, their caregivers, and physicians. NUPLAZID will be available through a specialty pharmacy network. Patients and physicians can access information about NUPLAZID and NUPLAZIDconnect by visiting www.nuplazid.com or calling 844-737-2223.

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

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: Strong CYP3A4 inhibitors (eg, ketoconazole) increase NUPLAZID concentrations. Reduce the NUPLAZID dose by one-half.

Strong CYP3A4 inducers may reduce NUPLAZID exposure, monitor for reduced efficacy. Increase in NUPLAZID dosage may be needed.

Renal Impairment: No dosage adjustment for NUPLAZID is needed in patients with mild to moderate renal impairment. Use of NUPLAZID is not recommended in patients with severe renal impairment.

Hepatic Impairment: Use of NUPLAZID is not recommended in patients with hepatic impairment. NUPLAZID has not been evaluated in this patient population.

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

Dosage and Administration: Recommended dose: 34 mg per day, taken orally as two 17 mg tablets once daily, without titration.
