Perrigo Settles Desloratadine Patent Litigation

The Perrigo Company announced today that all Hatch-Waxman litigation relating to Desloratadine tablets (5 mg) has been settled with Perrigo taking a license under all relevant patents. Perrigo had been sued for patent infringement of US Patent Nos. 6100274, 7214683 and 7214684 based upon its filing of an ANDA containing a Paragraph IV certification. Under the terms of the settlement, Perrigo can commercially launch its generic Desloratadine product on July 1, 2012, or earlier in certain circumstances. The new product launch may be a prescription or over-the-counter (OTC) product depending on its status at the time of launch. The Perrigo product is awaiting FDA approval.

This product seeks an AB-rating as equivalent to Schering-Plough's Clarinex(R) tablets (5 mg) indicated for the treatment of seasonal allergic rhinitis, perennial allergic rhinitis and chronic idiopathic urticaria. Sales for the brand were approximately $300 million, according to Wolters Kluwer data for the twelve months ending October 2008.
