Terrible news for MNTA but, fortunately, 180-day exclusivity hasn’t yet been determined; from MYL’s press release:
According to the FDA approval letter, Mylan was one of the first applicants to submit a substantially complete ANDA for Glatiramer Acetate Injection, 40 mg/mL, containing a Paragraph IV certification. Therefore, Mylan and other first filers may be eligible for 180 days of generic drug exclusivity but FDA has not made a formal determination on exclusivity at this time.
