The Efficacy of Istradefylline for Treating Mild Wearing-Off in Parkinson Disease [PDF]

Clinical Neuropharmacology, 2017
Objectives The adenosine A2A antagonist istradefylline has been used to treat Parkinson disease (PD) with symptoms of wearing-off since 2013 in Japan. Previous randomized controlled trials of istradefylline compared with placebo included PD patients experiencing an average daily OFF time of more than 2 hours.
