8-K: Lantheus Faces Patent Infringement Lawsuit Over Generic Cancer Drug

Lantheus Holdings is being sued by Novartis for patent infringement related to its generic version of the cancer drug LUTATHERA.

Summary

• Lantheus Holdings and its subsidiary, Lantheus Medical Imaging, have been sued for patent infringement by Advanced Accelerator Applications USA and Advanced Accelerator Applications SA, both Novartis entities.
• The lawsuit is in response to Lantheus' filing of an Abbreviated New Drug Application (ANDA) for Lutetium Lu 177 Dotatate (177Lu-PNT2003), a generic version of LUTATHERA.
• LUTATHERA is used to treat somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
• Lantheus believes it is the first applicant to file a substantially complete ANDA for this generic drug with a Paragraph IV certification, potentially entitling them to 180 days of generic marketing exclusivity in the U.S.
• The lawsuit was filed in the United States District Court for the District of Delaware.
