• Safinamide significantly improves motor function (primary efficacy variable: UPDRS III) in early Parkinson?s disease (PD) patients on a single dopamine agonist at a stable dose (MOTION study)
  • Safinamide significantly improves motor fluctuations (primary efficacy variable: ON time without troublesome dyskinesia) in mid-to late stage PD patients on levodopa and other PD drugs at a stable dose (SETTLE study)
  • Safinamide was very well tolerated in both studies with low drop out rates
  • Safinamide filing for regulatory approval as add-on in early and mid-to late PD patients in EU and US expected in Q4/2013

MILAN, Italy I March 19, 2013 I Newron Pharmaceuticals S.p.A. (?Newron?), a research and development company focused on novel CNS and pain therapies, and its partner Zambon S.p.A., a pharmaceutical company strongly committed to the respiratory, primary care and CNS therapeutic areas, presented results from the Phase III studies, MOTION and SETTLE, for safinamide at the 65th Annual Meeting of the American Academy of Neurology (AAN), on March 18, 2013.

MOTION* study was a six-month (24-week), randomized, double-blind, placebo-controlled international Phase III trial. It enrolled patients with early idiopathic PD (less than five years of disease duration) treated with a stable dose of a single dopamine agonist for at least four weeks. 679 patients were randomized equally to receive once daily safinamide 50 mg, or 100 mg, or matching placebo tablets as adjunctive treatment to a single dopamine agonist at a fixed dose. In accordance with international regulatory guidelines, the primary efficacy variable of the trial was the change in motor symptoms assessed by the change in the Unified Parkinson?s Disease Rating Scale (UPDRS) Part III score from baseline to week 24.

Safinamide was very well tolerated. 607 patients completed the trial; the drop-out rate was similar in all three treatment groups (approx. 11%). The most commonly reported adverse events were nausea, dizziness, somnolence, headache and back pain, with no significant difference in the incidence of any of these events among treatment groups. Similarly, the incidence of treatment induced abnormalities in laboratory results, ophthalmological examinations, vital signs and ECG was similar in all groups.

Analyses (On treatment, ANCOVA-LOCF) performed in the ITT population and the modified dopamine agonist monotherapy population (excluding 13 patients not meeting the major inclusion criteria of stable, dopamine agonist monotherapy) provided similar results. Treatment with safinamide 100 mg/day, compared with dopamine agonist alone (=placebo), improved the UPDRS III total score (change from base line to endpoint) by 1.04 ± 0.58 (p=0.07) and 1.20 ± 0.58 (p=0.039) in the ITT and modified dopamine agonist monotherapy population, respectively. Significant benefits of safinamide 100 mg/day were also noted in the PDQ39 (Parkinson?s Disease Quality of Life) and EQ-5D (European Quality of Life 5 domains).

SETTLE** study was a six-month (24-week), randomized, double-blind, placebo-controlled international Phase III trial. It enrolled 549 patients with mid-to late-stage idiopathic PD (more than three years of disease duration) treated with optimized, stable doses of levodopa and standard of care (dopamine agonist, COMT inhibitor, anticholinergic and/or amantadine) for at least four weeks. Patients who were experiencing a minimum of one and a half hours of ?OFF? time during the day were randomized equally to treatment with once a day safinamide (50-100mg) or placebo (standard of care including levodopa), as adjunctive treatment. Based on discussions with the regulatory authorities, the primary endpoint of the trial was the change in daily ?ON? time, as assessed by the patient completed daily diary cards (18 hours/day).

Safinamide was very well tolerated. 484 patients completed the trial; the drop-out rate was similar in both treatment groups (approx. 12%). The most commonly reported adverse events were nausea, urinary tract infections, falls, back pain and dyskinesia. Transient dyskinesia occurred more frequently with safinamide, but was mainly mild, and was not associated with treatment discontinuation. Similarly, the incidence of treatment induced abnormalities in laboratory results, ophthalmological examinations, vital signs and ECG was similar in all groups.

Analyses (On treatment, ANCOVA-LOCF) performed in the ITT population showed treatment with safinamide 50-100 mg/day significantly improved ON-Time without troublesome dyskinesia compared to placebo by 0.96 ± 0.21 hours (p<0.01) in the ITT. Significant benefits of safinamide 50-100 mg/day were also reported in OFF-time, Motor symptoms (UPDRS III), PDQ39, EQ-5D, clinical global impression of change and severity, and OFF-time post morning dose of levodopa.

?These results are extremely encouraging as they replicate previously reported results from safinamide studies in early and mid-to late stage PD patients. Based on the favourable side effect profile of safinamide, these benefits indicate safinamide will be a novel addition to the currently available therapeutic options for PD patients, as it will be the first add-on treatment for patients in both early and mid-to late PD? said Ravi Anand, Newron?s CMO.

?The results of SETTLE and MOTION show clear and multiple evidence of efficacy combined with a unique safety and tolerability profile. We are pleased to offer new hope to patients with PD? said Marco Sardina, Zambon?s CSO.

MOTION* and SETTLE** results are part of the clinical development program of safinamide, together with completed studies 009, 015, 016, designed to support an application for marketing authorization of safinamide as both an add-on therapy to dopamine agonist therapy in patients with early PD and as an add-on to levodopa therapy in patients with advanced PD. Newron and its partner Zambon plan to submit in the US and EU in Q4/2013.

Further MOTION and SETTLE study results after completion of ongoing analyses will be presented at the upcoming MDS meeting in June 2013.

* MOTION: SafinaMide add-On To dopamine agonist for early Idiopathic ParkinsON?s disease with motor fluctuations

** SETTLE: SafinamidE Treatment as add-on To LEvodopa in idiopathic Parkinson?s disease with motor fluctuations

About safinamide

Safinamide, an alpha-aminoamide, is currently being developed by Newron as an add-on therapy to dopamine agonists or to levodopa in patients with early or mid- to late-stage Parkinson?s disease (PD). It is believed to have both dopaminergic and non dopaminergic activities, including selective and reversible inhibition of monoamine oxidase B (MAO-B), activity-dependent sodium channel antagonism and inhibition of glutamate release in vitro.
