Our pipeline of product candidates is led by pimavanserin, which is in Phase III development as a potential first-in-class treatment for Parkinson’s disease psychosis. Pimavanserin also has the potential to address a range of other neurological and psychiatric disorders, including Alzheimer’s disease psychosis and schizophrenia, which also are underserved by currently marketed antipsychotic drugs. » DEAR FELLOW STOCKHOLDERS 2012 was a breakthrough year for ACADIA culminating with the impressive results from our pivotal Phase III -020 Study with pimavanserin for Parkinson’s disease psychosis (PDP) and our successful financing. These important achievements, coupled with our April 2013 announcement of an expedited path to NDA filing, provide a strong foundation for rapidly advancing pimavanserin to registration in PDP and strategically expanding the pimavanserin program into other important neurological and psychiatric indications. I believe that we are now well positioned to execute on our strategy of building a leading biopharmaceutical company dedicated to developing and commercializing innovative therapies that improve the lives of patients with neurological and related central nervous system disorders. Advancing our Phase III PDP Program to Registration Today, there are no drugs approved in the United States to treat PDP, a debilitating disorder that develops in up to 60 percent of Parkinson’s patients. PDP has a profound impact on and deeply affects the quality of life of patients, family members and caregivers. Among patients with Parkinson’s disease, psychosis is the leading cause of nursing home placement and it significantly increases their risk of morbidity and mortality. The strong data from our Phase III -020 Study represent a significant leap forward in the PDP field, potentially positioning pimavanserin to be the first drug approved in the United States for the treatment of this disorder. Dr. Jeffrey Cummings, M.D., Sc.D., Director of the Cleveland Clinic Lou Ruvo Center for Brain Health and a recognized expert in the field of neurology, presented detailed results from our -020 Study at the 65th American Academy of Neurology Meeting in March 2013. The -020 data showed robust and consistent efficacy of pimavanserin across a wide array of study measures and confirmed the positive top-line results that we announced in November 2012. Pimavanserin demonstrated highly significant antipsychotic efficacy in patients with PDP and allowed for maintained motor control. Highly significant improvements were also seen in all secondary efficacy measures. In addition, significant benefits were observed in exploratory measures of nighttime sleep, daytime wakefulness, and caregiver burden. Importantly, regardless of whether assessments were performed by independent blinded raters, site investigators, or caregivers, clear benefits of pimavanserin were observed. Consistent with previous studies, pimavanserin was safe and well tolerated in this Phase III trial. » 1 Neurology Psychiatry PARKINSON’S SCHIZOPHRENIA ALZHEIMER’S PSYCHOSIS DEPRESSION LEWY BODY DEMENTIA MANIA Pimavanserin has the potential to treat psychosis associated with neurological and psychiatric indications. Following the successful -020 Study, we met with who have completed our Phase III studies and who, the U.S. Food and Drug Administration (FDA) in in the opinion of the treating physician, may benefit April 2013. The FDA agreed that the data from our from continued treatment with pimavanserin. -020 Study, together with supportive data from other studies with pimavanserin, are sufficient to support We believe that, if approved, pimavanserin will the filing of a New Drug Application (NDA) for the represent the first effective and safe drug that will treatment of PDP. The outcome of this meeting treat the psychosis in patients with Parkinson’s represents another important step forward in our disease without compromising motor control, pimavanserin program. Importantly, we expect this thereby significantly improving the quality of life outcome will expedite the path to NDA filing and for these patients. Our strategy is to commercialize potential approval of pimavanserin, and may enable pimavanserin in the United States by establishing a pimavanserin to be available earlier than previously small specialty neurology sales force. We may choose expected to help Parkinson’s patients suffering to commercialize pimavanserin in markets outside of from psychosis. the United States through future strategic alliances.
