“We are delighted to pursue this clinical study in collaboration with Professor Ballard and King’s College London,” said Roger G. Mills, M.D., ACADIA’s Executive Vice President of Development and Chief Medical Officer. “We believe that their unique clinical research infrastructure and expertise will provide access to a pool of well-characterized ADP patients and enable the use of a small and geographically-focused group of highly trained raters, which we expect to enhance study precision.”About Alzheimer’s Disease Psychosis According to the Alzheimer’s Association, 5.4 million people in the United States are living with Alzheimer’s disease. While the criteria for diagnosing Alzheimer’s disease are mostly focused on cognitive deficits, it is often the psychiatric and related behavioral symptoms that are most troublesome for caregivers and lead to poor quality of life for patients. An estimated 25 to 50 percent of Alzheimer’s patients may develop Alzheimer’s disease psychosis (ADP), which is commonly characterized by disturbing visual hallucinations and delusions. The diagnosis of ADP is associated with more rapid cognitive and functional decline and institutionalization. There currently is no therapy approved for the treatment of ADP in the United States. About Pimavanserin Pimavanserin is ACADIA’s proprietary small molecule that acts selectively as an antagonist/inverse agonist on serotonin 5-HT 2A receptors. ACADIA has successfully completed a pivotal Phase III trial with pimavanserin, which demonstrated robust efficacy, tolerability and safety in patients with Parkinson’s disease psychosis (PDP), potentially positioning it to be the first drug approved in the United States for the treatment of this disorder. Pimavanserin is also in Phase II development for Alzheimer’s disease psychosis (ADP) and has completed a Phase II trial as a co-therapy in schizophrenia. Pimavanserin is formulated as a tablet and is administered orally once-a-day. ACADIA discovered pimavanserin and holds worldwide rights to this new chemical entity. About ACADIA Pharmaceuticals ACADIA is a biopharmaceutical company focused on innovative treatments that address unmet medical needs in neurological and related central nervous system disorders. ACADIA has a pipeline of product candidates led by pimavanserin, which is in Phase III development as a potential first-in-class treatment for Parkinson’s disease psychosis. ACADIA also has clinical-stage programs for chronic pain and glaucoma in collaboration with Allergan, Inc. and two advanced preclinical programs directed at Parkinson’s disease and other neurological disorders. All product candidates are small molecules that emanate from discoveries made at ACADIA. ACADIA maintains a website at www.acadia-pharm.com to which ACADIA regularly posts copies of its press releases as well as additional information and through which interested parties can subscribe to receive e-mail alerts.

These statements include but are not limited to statements related to the progress and timing of ACADIA’s drug discovery and development programs, including clinical trials and the results therefrom, and the potential of and the benefits to be derived from product candidates, in each case including pimavanserin. These statements also include any suggestion that the results from trials with pimavanserin in PDP will be predictive of results in the -019 Study for ADP or whether the use of a geographically-focused group of raters will enhance precision in the -019 Study. These statements are only predictions based on current information and expectations and involve a number of risks and uncertainties. Actual events or results may differ materially from those projected in any of such statements due to various factors, including the risks and uncertainties inherent in drug discovery, development and commercialization and collaborations with others, and the fact that past results of clinical trials may not be indicative of future trial results. For a discussion of these and other factors, please refer to ACADIA’s annual report on Form 10-K for the year ended December 31, 2012 as well as ACADIA’s subsequent filings with the Securities and Exchange Commission. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
