Mylan Confirms Patent Challenge Relating To Nexavar

(RTTNews) - Generic drugmaker Mylan Inc. (MYL) confirmed Monday that it and its subsidiary Mylan Pharmaceuticals have been sued by Bayer Healthcare LLC, Bayer Healthcare Pharmaceuticals Inc., and Onyx Pharmaceuticals Inc., in connection with the filing of an Abbreviated New Drug Application with the U.S. Food and Drug Administration for Sorafenib Tablets, 200 mg.

The product is the generic version of Nexavar, which is indicated for the treatment of certain types of cancers including unresectable hepatocellular carcinoma and advanced renal cell carcinoma.

Mylan believes that it is the first company to have filed a substantially complete ANDA containing a Paragraph IV certification for the product and expects to be eligible for 180 days of marketing exclusivity upon receiving final FDA approval.

The plaintiffs have filed suit against the Mylan companies in the United States District Court in the District of Delaware.

For the 12 months ending December 31, 2014, Nexavar had U.S. sales of about $48 million, according to IMS Health.
