Among patients who had been visiting the clinical research centers between May 2013 and 30th September 2015, those receiving istradefylline, a Parkinson's disease treatment, for more than 12 months will be selected and the long-term clinical efficacy and safety of istradefylline will be evaluated based on patient demographic data (age, gender, drug history, medical history/concurrent conditions, H&Y stage, disease duration, history of DBS and others), clinical evaluation related to Parkinson's disease (UPDRS, CGI), non-motor symptoms, associated symptoms of the disease (BDI-II, JESS), MMSE, and clinical data related to safety.
Endpoints were evaluated before treatment and at 3, 6 and 12 months after treatment.
