Safinamide for advanced Parkinson's disease.!

Safinamide

We knew that ‘Safinamide” is a candidate drug against Alzheimer's disease. In 2007, a Phase III clinical trial, was started by Merck-Serono for Safinamide as add-on to dopamine agonist for early idiopathic Parkinson's disease. Now thanx to the same companies for having second phase III trial of Safinamide in advanced Parkinson's disease. Interestingly the same compound has been tested for restless legs syndrome (RLS) and epilepsy As of 2008^[update], they are in Phase II.

Safinamide is believed to have a novel dual mechanism of action based on the enhancement of the dopaminergic function (through reversible inhibition of monoamine oxidase-B [MAO-B] and dopamine uptake) and reduction of glutamatergic activity by inhibiting glutamate release.

The earlier trials revealed that safinamide significantly improved motor function in patients with advanced Parkinson's disease. And also the results are encouraging and suggest that safinamide could have benefits beyond motor symptoms. The earlier results not only substantiates the claims but also established something interesting factors like ability of safinamide to improve depressive symptoms are important aspects of PD in addition to the other benefits. Hope after few days safinamide as an add-on therapy to levodopa will come in the market as a boon to those who are mid-to late-stage idiopathic Parkinson's disease (more than five years of disease duration).....

Newron, Zambon announce re-submission of safinamide NDA to FDA

In continuation of my update on safinamide 

Newron Pharmaceuticals S.p.A. ("Newron"), a research and development company focused on novel CNS and pain therapies, and its commercial and development partner Zambon S.p.A., an international pharmaceutical company, announced  that the NDA for safinamide has been re-submitted to the US FDA. This follows the announcement last week that the CHMP has given a positive opinion on safinamide for Europe.

The submission covers the indications "safinamide as add-on therapy to a stable dose of a single dopamine agonist" in early Parkinson's disease patients and "safinamide as add-on therapy to levodopa alone or in combination with other Parkinson's disease treatments" in mid-to late stage Parkinson's disease patients.

The first submission of safinamide to the US FDA was made in May 2014. On review, the FDA issued a Refusal to File (RTF) letter based on organizational and navigational problems, largely due relating to the hyperlinking of tables, folders and the organization of the table of contents in the submission.

Ravi Anand, Newron's CMO, stated: "Newron has been in frequent contact with the FDA to propose solutions to the technical issues and obtain their concurrence with the proposals. These discussions lead Newron to conclude that the RTF issues have been addressed in this submission."
