As a result of file organizational problems, the FDA sent Neuron a Refusal to File (RTA) letter with regard to their initial NDA filing in May. Newron announced today that the NDA for Safinamide has been re-submitted to the FDA. This follows the announcement last week that the CHMP has given a positive opinion on safinamide for Europe. It really is amazing that it takes 6 months for the FDA to reject a submittal and for the company to then resubmit. Just another reason for the unbearable timeline involved in getting a new drug approval.
