Current Clinical Research Trials for Movement Disorders

Researchers at The GW Medical Faculty Associate’s Center for Movement Disorders are conducting clinical research trials to learn more about treating movement disorders. 

Clinical research trials search for new ways to prevent, understand and/or treat disease. The goal of these trials is to see if a new treatment, procedure or device works and is safe to use.  Participating in a research trial, as either a healthy volunteer or a patient volunteer, is an opportunity to help researchers find better treatments for others in the future.



Title: Management of Parkinson’s Disease Psychosis in Actual Practice (The INSYTE Study)

Principal Investigator: Pritha Ghosh, M.D.

Status of Research Trial: Open to enrollment

Sponsor of Research Trial: ACADIA Pharmaceuticals Inc.

Description of Research Trial:

Psychosis commonly occurs in patients with Parkinson disease. Parkinson’s disease psychosis (PDP) involves an array of neuropsychiatric symptoms, particularly hallucinations and delusions, and presents a clinical profile that is distinct from that commonly observed with substance-induced psychosis and other psychotic disorders. The INSYTE Study will endeavor to provide a better understanding about how PDP is managed in “real world” clinical settings, and the role of medication adjustments and anti-psychotic therapy in addressing the condition.
