Financial Results

Revenue

ACADIA reported net product sales of $5.3 million for the three months ended September 30, 2016. No similar net product sales were reported for the comparable period of 2015. NUPLAZID was made available for prescription starting May 31, 2016. Through ACADIA’s NUPLAZIDconnect™ site, upon initiation of therapy, physicians are able to prescribe patients a 30-day free trial of NUPLAZID for which no revenue is recognized.

Research and Development

Research and development expenses increased to $25.8 million for the three months ended September 30, 2016 from $18.7 million for the comparable period of 2015. This increase was primarily due to increased clinical costs related to the development of pimavanserin in indications other than Parkinson’s disease psychosis and an increase in personnel and related costs associated with ACADIA’s expanded research and development organization.

Selling, General and Administrative

Selling, general and administrative expenses increased to $50.5 million for the three months ended September 30, 2016 from $20.3 million for the comparable period of 2015. This increase was primarily due to costs related to the hiring of our specialty sales force in April 2016 and costs incurred to support our commercial activities for NUPLAZID.

Net Loss

For the three and nine months ended September 30, 2016, ACADIA reported a net loss of $71.6 million and $192.7 million, or $0.61 and $1.69 per common share, respectively, compared to a net loss of $38.9 million and $118.7 million, or $0.39 and $1.18 per common share, for the comparable periods of 2015, respectively. The net losses for the three and nine months ended September 30, 2016 included $14.0 million and $39.8 million, respectively, of non-cash stock-based compensation expense compared to $9.3 million and $31.3 million for the comparable periods of 2015, respectively.

Cash and Investments

At September 30, 2016, ACADIA’s cash, cash equivalents and investment securities totaled $588.9 million, compared to $215.1 million at December 31, 2015.

Important Safety Information and Indication for NUPLAZID (pimavanserin) tablets

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.

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.

Pregnancy: Use of NUPLAZID in pregnant women has not been evaluated and should therefore be used in pregnancy only if the potential benefit justifies the potential risk to the mother and fetus.

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.
