Mylan Faces Suit on Transdermal Product
Mylan N.V. has confirmed that it and its subsidiaries Mylan Pharmaceuticals Inc. and Mylan Technologies Inc. have been sued by Noven Pharmaceuticals Inc. and Hisamitsu Pharmaceutical Co., Inc., in connection with the filing of an abbreviated new drug application (ANDA) with the US Food and Drug Administration (FDA) for estradiol transdermal System, USP, “Twice-Weekly” 0.0375 mg/day, 0.05 mg/day, 0.075 mg/day and 0.1 mg/day. This product is the generic version of Minivelle, which is indicated for the treatment of moderate to severe vasomotor symptoms due to menopause and the prevention of postmenopausal osteoporosis.
Mylan’s ANDA for a generic Minivelle is one of six Mylan applications for transdermal products pending FDA approval, representing $3.6 billion in annual sales. Mylan currently markets seven transdermal product families in the US, of which three form part of the company’s women’s health portfolio.
Mylan believes that it is the first company, or among the first companies, to have filed a substantially complete ANDA containing a Paragraph IV certification for this product and expects to be eligible for 180 days of marketing exclusivity upon receiving final FDA approval. The plaintiffs filed suit against the Mylan companies in the United States District Court in the District of Delaware.
For the 12 months ending February 2015, Minivelle had US sales of approximately $115 million, according to IMS Health and as reported by Mylan.
