ACADIA Pharmaceuticals Reports First Quarter 2009 Financial Results

SAN DIEGO—(BUSINESS WIRE)—May. 11, 2009—ACADIA Pharmaceuticals Inc. (Nasdaq: ACAD), a biopharmaceutical company utilizing innovative technology to fuel drug discovery and clinical development of novel treatments for central nervous system disorders, today reported its unaudited financial results for the first quarter ended March 31, 2009.

ACADIA reported a net loss of $15.0 million, or $0.40 per common share, for the first quarter of 2009 compared to a net loss of $16.4 million, or $0.44 per common share, for the first quarter of 2008. The net losses for the first quarters of 2009 and 2008 included $575,000 and $836,000, respectively, in non-cash, stock-based compensation expense.

At March 31, 2009, ACADIA’s cash, cash equivalents, and investment securities totaled $46.4 million compared to $60.1 million at December 31, 2008. Following the end of the first quarter, ACADIA received an upfront cash payment of $30 million under the terms of its collaboration with Biovail Laboratories International SRL, which was established in early May 2009.

“The beginning of 2009 has been a highly productive period for ACADIA, highlighted by the formation of two important new collaborations with Biovail and Meiji Seika, and the completion of enrollment in our first pivotal Phase III trial with pimavanserin in patients with Parkinson’s disease psychosis,” said Uli Hacksell, Ph.D., ACADIA’s Chief Executive Officer. “We believe that ACADIA is well positioned to continue to advance our promising portfolio of product candidates that provide us with multiple product and commercial opportunities.”

Revenues totaled $374,000 for the first quarter of 2009 compared to $806,000 for the first quarter of 2008. This decrease was primarily due to lower revenues from ACADIA’s collaborations with Allergan and its agreements with other parties.

Research and development expenses totaled $12.6 million for the first quarter of 2009, including $221,000 in stock-based compensation, compared to $15.2 million for the first quarter of 2008, including $415,000 in stock-based compensation. The decrease in research and development expenses was primarily due to approximately $3.9 million in decreased personnel and other costs associated with the research and development organization following ACADIA’s restructuring in August 2008, offset in part by $1.3 million in increased external service costs. External service costs totaled $9.1 million for the first quarter of 2009 and were primarily comprised of development costs for pimavanserin.

General and administrative expenses totaled $3.0 million for the first quarter of 2009, including $354,000 in stock-based compensation, compared to $3.3 million for the first quarter of 2008, including $421,000 in stock-based compensation. The decrease in general and administrative expenses was primarily due to decreased personnel and other administrative costs resulting from ACADIA’s restructuring, offset in part by increased external expenses.

Net interest income decreased to $167,000 for the first quarter of 2009 from $1.3 million in the comparable quarter of 2008 due to decreased yields on ACADIA's investment security portfolio and lower average levels of cash and investment securities.

ACADIA anticipates that its cash, cash equivalents and investment securities will be greater than $40 million at December 31, 2009, and that its existing cash resources and payments from its collaborations will be sufficient to fund its operations at least into the first half of 2011.

First Quarter 2009 and Recent Highlights

• ACADIA announced completion of enrollment in the first pivotal Phase III trial of pimavanserin in patients with Parkinson’s disease psychosis (PDP) in early May 2009. Top-line results from this trial are expected to be reported by the end of the third quarter of 2009.
• ACADIA is continuing to enroll patients in the second pivotal Phase III trial of pimavanserin in patients with PDP. ACADIA also is continuing to conduct an open-label safety extension study pursuant to which eligible patients who have completed either of the two pivotal Phase III trials have the opportunity to enroll if, in the opinion of the physician, a patient may benefit from continued treatment with pimavanserin.
• ACADIA established a collaboration with Biovail Laboratories International SRL to co-develop and commercialize pimavanserin for neurological and psychiatric indications, including PDP and Alzheimer’s disease psychosis (ADP), in the United States and Canada.
• ACADIA established a collaboration with Meiji Seika Kaisha, Ltd. to develop and commercialize a novel class of pro-cognitive drugs to treat patients with schizophrenia and related disorders in Japan and several other Asian countries.
