ACADIA Pharmaceuticals Initiates Second Phase III Trial with Pimavanserin in Patients with Parkinson's Disease PsychosisSAN DIEGO--(HSMN NewsFeed)--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 announced that it has initiated its second Phase III trial designed to evaluate the safety and efficacy of pimavanserin as a treatment for Parkinsonís disease psychosis (PDP).
ďThe start of our second Phase III pivotal trial represents another important step forward toward our goal of providing a first-in-class treatment for patients with PDP,Ē said Uli Hacksell, Ph.D., Chief Executive Officer of ACADIA Pharmaceuticals. ďWe believe pimavanserin may provide a unique combination of antipsychotic efficacy, motoric tolerability and safety and, therefore, provides the potential for an important advance in therapy for patients suffering from this debilitating disorder.Ē
The Phase III trial is a multi-center, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of pimavanserin in approximately 240 patients with PDP. Patients in the trial will be randomized to three different study arms, which will include two different doses of pimavanserin and one placebo arm. Patients will receive oral doses of either pimavanserin or placebo once daily for six weeks in addition to stable doses of their existing dopamine replacement therapy. The primary endpoint of the trial is antipsychotic efficacy as measured by the Scale for the Assessment of Positive Symptoms, or SAPS. Motoric tolerability will be an important secondary endpoint in the trial and will be measured using the Unified Parkinsonís Disease Rating Scale, or UPDRS.
ACADIA is also currently conducting an open-label safety extension study under which patients who have completed either of the Phase III PDP trials will have the opportunity to enroll if, in the opinion of the physician, the patient may benefit from continued treatment with pimavanserin.
Pimavanserin tartrate is a novel, potent, and selective 5-HT2A inverse agonist that ACADIA discovered and is developing as a treatment for PDP. ACADIA is currently conducting two Phase III pivotal trials in its program with pimavanserin as a treatment for PDP. ACADIA has also reported positive results from a Phase II trial in its program with pimavanserin as a co-therapy for schizophrenia.
About Parkinsonís Disease Psychosis (PDP)
Parkinsonís disease is a chronic neurological disorder that results from the degeneration of neurons in a region of the brain that controls movement. According to the American Parkinsonís Disease Association, over 1.5 million people in the United States suffer from this disease. Studies have suggested that up to 40 percent of patients with Parkinsonís disease will develop psychotic symptoms, commonly consisting of visual hallucinations and delusions. The development of psychosis in patients with Parkinsonís disease often disrupts their ability to perform many of the activities of daily living that keep them independent and active. As a result, Parkinsonís disease psychosis is associated with increased caregiver burden, nursing home placement, and increased mortality.
