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.

Exclusion criteria

Exclusion criteria: · The patient has any indication of forms of parkinsonism other than idiopathic Parkinson’s Disease. · The patient is currently experiencing end of dose wearing off or on-off phenomena, disabling peak dose or biphasic dyskinesias, or unpredictable or widely swinging fluctuations. · The patient has a concomitant disease likely to interfere with the study · The patient has hypersensitivity or contraindications to MAO-B inhibitors. · The patient has participated in a previous clinical trial within 30 days of entry into the study (screening visit) or has received treatment with any investigational compound within 30 days or 5 half-lives, whichever is longer, prior to screening. · The patient has received treatment of his/her parkinsonian symptoms with a medication, other than a single dopamine agonist, during the 4 weeks preceding the screening visit. · The patient has received treatment with opioids, SNRIs, tri- or tetra-cyclic antidepressants, MAO inhibitors (e.g. selegiline), meperidine derivatives, oral neuroleptics or any agent known to significantly inhibit or induce drug-metabolizing enzymes within 4 weeks prior to the screening visit. · The patient has received a depot neuroleptic within one injection cycle. · The patient has received treatment with a drug that has hepatotoxic potential, e.g., tamoxifen, within 4 weeks, or received radiation therapy or a drug with cytotoxic potential, e.g, chemotherapy, within one year prior to the screening visit.

Design outcomes

Primary

MeasureTime frame
Main Objective: The objectives of this study are to evaluate the safety and efficacy of two dose ranges of safinamide (50-100 and 150-200 mg/day, p.o.), 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.;Secondary Objective: ;Primary end point(s): 1. Change in mean value of UPDRS - Section III total score from baseline to endpoint. 2. CGI - Change from baseline to endpoint (proportion of patients showing improvement – scores of 1, 2 or 3).
