Sepracor jointly with University of Massachusetts has moved a civil action for patent infringement against Indian generic drug manufacturer Glenmark Pharmaceuticals alleging infringement of the US Patent Nos. 7,214,683 (the ‘683 patent) and 7,214,684 (the ‘684 patent) covering anti-allergic drug Clarinex, generically known as Desloratidine. The complaint filed in the US District Court for the District of New Jersey, is in response to Glenmark submission of an Abbreviated New Drug Application (ANDA) No. 78-362 with the US Food and Drug Administration seeking approval to commercially market the generic (bioequivalent) version of Clarinex before the expiration of the ‘683 and ‘684 patents. The ‘683 patent covers oral pharmaceutical composition of Desloratidine whereas the ‘684 patent relates to method of treating allergic rhinitis.
