The suit was triggered by notifications received from Mylan beginning in mid-September, in which Mylan stated that it had filed a NDA (505(b)(2) New Drug Application) with the FDA for insulin glargine pre-filled pen and vial drug products. Mylan also stated that its NDA included a paragraph IV certification challenging all of the Sanofi patents then listed in the FDA Orange Book for Sanofi's Lantus (insulin glargine injection, 100 Units/mL) and Lantus SoloStar products.
