MILAN, Italy--(BUSINESS WIRE)--Newron Pharmaceuticals S.p.A. (“Newron”) (SIX: NWRN, XETRA: NP5), a biopharmaceutical company focused on the development of novel therapies for patients with diseases of the central and peripheral nervous system, today announced an agreement regarding a potentially pivotal study to evaluate the efficacy of safinamide in Parkinson’s disease patients with levodopa induced dyskinesia (PD LID). Positive results from the study could result in a label extension for safinamide, subject to regulatory approval.
Under the agreement with its partner Zambon, Newron will sponsor the study and be responsible for its development and execution, as well as leading on all related regulatory interactions. Newron and Zambon will evenly share the cost of the study.
The double-blind, placebo-controlled study is intended to be performed in the US, Europe and Asia/Australia, with the aim of a label extension for safinamide in key markets. Safinamide has previously been approved for the treatment of Parkinson’s disease as add-on therapy to levodopa/carbidopa experiencing “off” episodes in 20 markets including: the European Union, Switzerland, the United Kingdom, the United States, Canada, Australia, Latin America, Israel, the United Arab Emirates, Japan and South Korea. Safinamide is commercialized by Zambon as well as Meiji Seika/Eisai. Supernus Pharmaceuticals, a company focused on the development and commercialization of products for the treatment of CNS diseases, acquired the US commercialization rights for safinamide in 2020.
Ravi Anand, CMO of Newron, said: “Previous pre-clinical and clinical studies have provided preliminary evidence of the efficacy of safinamide in reducing dyskinesia. We will be working with international clinical experts and regulatory authorities to finalize the design of a global trial to demonstrate the benefits of safinamide on dyskinesia in patients with PD.”
Paola Castellani, CMO and R&D Head of Zambon, added: “Since 2015, thousands of Parkinson’s disease patients around the world have benefited from safinamide’s safe and efficacious profile and the subsequent improvement in their motor fluctuations. We look forward to working closely with Newron to potentially provide a new treatment option for those living with PD LID, an area of huge medical need.”
Jonathan Rubin, CMO of Supernus Pharmaceuticals, stated: “We welcome the agreement reached between our partners and look forward to the next steps towards the initiation of the study. Supernus recognizes the substantial potential benefits a label extension covering PD LID, if approved by the FDA, would offer to the patients.”
Parkinson’s disease affects an estimated seven to ten million patients worldwide. More than 40% of Parkinson patients experience PD LID, involuntary, non-rhythmic and often painful movements during waking hours that are purposeless and unpredictable. Dyskinesia can interfere with people's daily living, resulting in functional impairment and disability. People with Parkinson's disease often experience multiple fluctuating periods of OFF time and dyskinesia during any given day, which can impede their movement and daily function. Currently, only one drug has ever received marketing authorization for PD LID in the US.
About safinamide
Safinamide is a new chemical entity with a unique mode of action including selective and reversible MAO-B-inhibition and blocking of voltage dependent sodium channels which leads to modulation of abnormal glutamate release. Clinical trials have established its efficacy in controlling motor symptoms and motor complications in the short term, maintaining this effect over 2 years. Results from 24-month double-blind controlled studies suggest that safinamide shows statistically significant effects on motor fluctuations (ON/OFF time) without increasing the risk of developing troublesome dyskinesia. This effect may be related to its dual mechanism acting on both the dopaminergic and the glutamatergic pathways. Safinamide is a once-daily dose and has no diet restrictions due to its high MAO-B/MAO-A selectivity. Zambon has the rights to develop and commercialize Safinamide globally, excluding Japan and other key Asian territories where Meiji Seika has the rights to develop and commercialize safinamide. The rights to develop and commercialize Safinamide in the USA have been acquired by Supernus Pharmaceuticals. Safinamide is commercialized under different brand names: Onstryv® in Canada, Equfina® in Japan and South Korea and Xadago® in the rest of the world.

About Parkinson’s disease and Levodopa (L-dopa) Induced Dyskinesia (LID)
PD is the second most common chronic progressive neurodegenerative disorder in the elderly after Alzheimer’s disease, affecting 1-2% of individuals aged ≥ 65 years worldwide. The prevalence of the PD market is expected to grow in the next years due to the increase in the global population and advancements in healthcare that contribute to an aging population at increased risk for PD. The diagnosis of PD is mainly based on observational criteria of muscular rigidity, resting tremor, or postural instability in combination with bradykinesia. As the disease progresses, symptoms become more severe. Early-stage patients are more easily managed on L-dopa. L-dopa remains as the most effective treatment for PD, and over 75% of the patients with PD receive L-dopa. However, long term treatment with L-dopa leads to seriously debilitating motor fluctuations, i.e. phases of normal functioning (ON-time) and decreased functioning (OFF-time). Furthermore, as a result of the use of high doses of L-dopa with increasing severity of the disease, more than 40% of patients experience L-dopa-Induced Dyskinesia, involuntary and non-rhythmic movements during waking hours that are purposeless and unpredictable. Dyskinesia can interfere with people's daily living, resulting in functional impairment and disability. People with Parkinson's disease often experience multiple fluctuating periods of OFF time and dyskinesia during any given day, which can impede their movement and daily function. As the disease progresses, more drugs are used as an add-on to what the patient already takes, and the focus is to treat symptoms while managing LID and the “off-time” effects of L-dopa. Most current therapies target the dopaminergic system that is implicated in the pathogenesis of PD, and most current treatments act by increasing dopaminergic transmission that leads to amelioration of motor symptoms.
