Glenmark Generics has filed an Abbreviated New Drug Application (ANDA) for Azelaic Acid, Gel 15 per cent Topical, with the US Food and Drug Administration (FDA) with a Paragraph IV Certification for the Orange-Book listed patent.
Glenmark’s ANDA product is a generic version of FINACEA, which is indicated for the topical treatment of inflammatory papules and pustules of mild to moderate rosacea. Intendis, Intraserv, Bayer Healthcare Pharmaceuticals filed suit against Glenmark Generics and Glenmark Generics on March 14, 2013, in the United States District Court for the District of Delaware, seeking to prevent Glenmark from commercialising its ANDA product prior to the expiration of US Patent No. 6,534,070. This lawsuit was filed under the provisions of the Hatch-Waxman Act, which triggers a stay of final FDA approval of Glenmark’s ANDA product for up to 30 months or until final resolution of the matter before the Court, whichever occurs sooner.
Based on available information, Glenmark believes it may be a ‘first applicant’ to file an ANDA for the generic version of FINACEA and may be entitled to 180 days of generic market exclusivity.
According to the IMS health data for the twelve months ending September 30, 2012, FINACEA had total US sales of approximately $95 million.
