ACADIA Pharmaceuticals Reports Third Quarter 2007 Financial Results

SAN DIEGO–(BUSINESS WIRE)–Nov. 5, 2007–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 third quarter and nine months ended September 30, 2007.

ACADIA reported a net loss of $16.0 million, or $0.43 per common share, for the third quarter of 2007 compared to a net loss of $11.3 million, or $0.38 per common share, for the third quarter of 2006. For the nine months ended September 30, 2007, ACADIA reported a net loss of $39.4 million, or $1.14 per common share, compared to a net loss of $32.6 million, or $1.20 per common share, for the comparable period of 2006.

At September 30, 2007, ACADIA’s cash, cash equivalents, and investment securities totaled $141.0 million compared to $83.3 million at December 31, 2006. The increase in cash was primarily due to $96.1 million in net proceeds raised in a public offering of common stock, partially offset by cash used to fund ACADIA’s operations.

“The third quarter of 2007 was highlighted by continued progress with the ongoing trials in our advanced clinical programs, including the first pivotal trial in our Phase III program with pimavanserin for Parkinson’s disease psychosis and the Phase IIb trial with ACP-104 for schizophrenia,” said Uli Hacksell, Ph.D., ACADIA’s Chief Executive Officer. “Meanwhile, having completed our full analysis of the data from our Phase II schizophrenia co-therapy trial with pimavanserin, we are excited to present these data at the December meeting of the American College of Neuropsychopharmacology. In addition, we will present these data and other information on our programs at ACADIA’s inaugural analyst/investor day, which we have scheduled immediately following this prestigious medical meeting.”

Revenues totaled $2.0 million for the third quarter of 2007 compared to $1.9 million for the third quarter of 2006, and were comprised of revenues earned from ACADIA’s collaborations with Sepracor Inc. and Allergan, Inc. as well as its agreements with other parties.

Research and development expenses totaled $16.9 million for the third quarter of 2007, including $805,000 in stock-based compensation, compared to $15.5 million for the third quarter of 2006, including $550,000 in stock-based compensation. The increase in research and development expenses was primarily due to increased costs associated with ongoing trials in ACADIA’s advanced clinical programs, including $655,000 in increased fees paid to external service providers, which totaled $9.7 million for the third quarter of 2007, and increased costs associated with expansion of ACADIA’s development organization.

General and administrative expenses totaled $2.9 million for the third quarter of 2007, including $441,000 in stock-based compensation, compared to $3.0 million for the third quarter of 2006, including $421,000 in stock-based compensation.

The results for the comparable quarter and nine month periods of 2006 included a gain of $4.0 million and $3.6 million, respectively, related to settlement of a civil action.

Third Quarter 2007 and Recent Highlights

  • ACADIA, in collaboration with Herbert Y. Meltzer, M.D., Professor of Psychiatry and Pharmacology and Director of the Psychosis Program at the Vanderbilt School of Medicine, is preparing to present data from its Phase II schizophrenia co-therapy trial with pimavanserin at the 46th Annual Meeting of the American College of Neuropsychopharmacology to be held in Boca Raton, Florida from December 9-13, 2007. Dr. Meltzer’s presentation will reflect data from the full analysis of this Phase II schizophrenia co-therapy trial. This analysis confirmed the robustness of the top-line results reported in March 2007 and provided additional data in support of the benefits of pimavanserin co-therapy when combined with a sub-maximal dose of risperidone.
  • ACADIA announced today that it will host an analyst/investor meeting in New York City on Friday, December 14, 2007. The event will feature a presentation of data from ACADIA’s Phase II schizophrenia co-therapy trial with pimavanserin together with presentations of ACADIA’s Phase III program with pimavanserin for Parkinson’s disease psychosis (PDP), its Phase II program with ACP-104 for schizophrenia, and other discovery and development activities.
  • ACADIA continues to enroll patients in its Phase IIb clinical trial with ACP-104. This double-blind, placebo-controlled trial is designed to evaluate the safety and efficacy of ACP-104 in approximately 250 patients with schizophrenia who are experiencing an acute psychotic episode. ACADIA expects to report top-line results from this trial during the third quarter of 2008.
  • ACADIA continues to enroll patients in its first pivotal Phase III trial with pimavanserin as a treatment for PDP. The double-blind, placebo-controlled trial is designed to evaluate the safety and efficacy of pimavanserin in approximately 240 patients with PDP. ACADIA expects to report top-line results from this trial during 2009.
  • ACADIA announced in July that it earned a milestone payment associated with Allergan’s initiation of an exploratory clinical study with a small molecule drug candidate for the treatment of glaucoma.
  • ACADIA was selected to be one of the inaugural companies in the new NASDAQ NeuroInsights Neurotech Index, which was launched on September 25, 2007.
