Title

Safinamide as Add-On Therapy in Patients With Early Idiopathic Parkinson's Disease Treated With a Stable Dose of a Single Dopamine Agonist
A Phase III, Double-Blind, Placebo-Controlled Study to Determine the Efficacy and Safety of a Low (50 100 mg/Day) and High (150 200 mg/Day) Dose Range of Safinamide as Add-On Therapy in Patients With Early Idiopathic Parkinson's Disease Treated With a Stable Dose of a Single Dopamine Agonist

To evaluate the safety and efficacy of two dose ranges of safinamide (High Dose: 150 to 200 mg/day and Low Dose: 50 to 100 mg/day) orally, as compared to Placebo, as add-on therapy in patients with early idiopathic Parkinson's disease who are currently receiving a stable dose of a single dopamine agonist. It is hypothesized that, over a 24-week period, add-on treatment with safinamide will result in greater improvement of motor symptoms in these patients, compared to treatment with a dopamine agonist alone.
