Mylan Announces IPR Proceedings For Sanofi's Lantus Patents

Mylan N.V. (NASDAQ:MYL) announced that the U.S. Patent and Trademark Appeal Board (“PTAB”) has instituted inter partes review (“IPR”) proceedings on all claims against two Orange Book-listed patents — U.S. Patent Nos. 7,476,652 and 7,713,930, respectively.

The two patents are owned by Sanofi (NYSE:SNY) for Lantus (insulin glargine injection) 100 Units/mL.

We remind investors that Mylan's 505(b)(2) new drug application (“NDA”) for Insulin Glargine in vial and pen dosage forms is under active review with the FDA.

In October, Sanofi initiated a patent infringement litigation against Mylan's NDA in the United States District Court for the District of New Jersey alleging violation of 18 patents in the suit inclusive of these two Lantus patents.

Lantus and Lantus Solostar are both approved for improving glycemic control in adult patients with diabetes mellitus.

Sanofi’s diabetes franchise seems highly weighed on with its key product Lantus facing a tremendous competitive pressure at the payor level as well as from other biosimilars in several European markets besides Japan. Moreover, a biosimilar version of Lantus had hit the markets last December.
