Clinical Research Study for Individuals with Parkinson’s Disease (PD) Who are Currently Experiencing Inadequately Controlled Depression

Purpose The primary objective of this multi-center, open-label study is to assess the effectiveness and safety of the investigational study drug Pimavanserin in individuals with Parkinson’s disease (PD) who have depression that is not adequately controlled by their current antidepressant.
Summary According to the National Parkinson Foundation, about one million people in the United States suffer from Parkinson’s disease (PD). Parkinson’s disease is a progressive neurodegenerative disorder characterized primarily by motor deficits; however, there are also associated behavioral symptoms that are frequent, severe, and disabling. Mood disorders and, in particular, depression occur in approximately 50% of individuals with PD. Symptoms of depression in Parkinson’s disease are associated with increased morbidity and diminished quality of life. Conversely, improved depression is associated with reduced physical disability and improved quality of life.

The management of PD related depression represents a major unmet need in PD. Pimavanserin is an investigational new drug being evaluated by ACADIA Pharmaceuticals for inadequately controlled depression in adults with Parkinson’s disease.
