Abbreviated New Drug Application
In January 2025, the Company received a Paragraph IV notice of certification (the “Notice Letter”) from Annora Pharma Private Limited (“Annora”) advising that Annora has submitted an Abbreviated New Drug Application (“ANDA”) to the FDA seeking approval to manufacture, use or sell a generic version of ORLADEYO in the United States prior to the expiration of three patents listed in the FDA’s Orange Book: U.S. Patent Nos. 10,662,160; 11,117,867; and 11,618,733 (the “Challenged Patents”). The Notice Letter alleges that the Challenged Patents, which expire in 2039, are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Annora’s ANDA. The Notice Letter does not challenge the following six ORLADEYO Orange Book patents that expire in 2035: U.S. Patent Nos. 10,125,102; 10,329,260; 10,689,346; 11,230,530; 11,708,333; and 12,116,346.
On March 10, 2025, the Company filed a patent infringement lawsuit in the United States District Court for the District of Delaware against Annora, Hetero Labs Limited, Hetero USA, Inc., and Camber Pharmaceuticals, Inc. (collectively, the “Defendants”), asserting infringement of the Challenged Patents arising from Annora’s ANDA filing with the FDA. The Company is seeking, among other remedies, equitable relief enjoining the Defendants from infringing the Challenged Patents, as well as an order that the effective date of any FDA approval of the ANDA would be a date no earlier than the expiration of the Challenged Patents (including any regulatory extensions). While the Company intends to vigorously defend its intellectual property rights protecting ORLADEYO, this matter is in the early stages of litigation and no assessment can be made as to the likely outcome of this matter or whether it will be material to the Company. Accordingly, an estimate of the potential loss, or range of loss, if any, to the Company relating to this matter is not possible at this time.
