FDA APPROVES NEW ADD-ON DRUG TO TREAT OFF EPISODES IN ADULTS WITH PARKINSON’S DISEASE
Istradefylline (Nourianz, Kyowa Kirin) tablets have been approved by the US Food and Drug Administration (FDA) as add-on treatment to levodopa/carbidopa in adults who have Parkinson’s disease (PD) experiencing “off” episodes. Eric Bastings, M.D., acting director of the Division of Neurology Products in the FDA’s Centre for Drug Evaluation and Research said “Parkinson’s disease is a debilitating condition that profoundly impacts patients’ lives.” Istradefylline is a selective adenosine A2A receptor antagonist. When treated on ‘off’ episodes in patients with PD taking levodopa/carbidopa its effectiveness was shown in four 12-week, placebo-controlled clinical studies that included a total of 1143 participants. According to all the four studies, it reports that the addition of istradefylline leads to a statistically significant decrease from baseline in daily “off” time relative to placebo add-on, the FDA stated in a news release.
