Eagle Pharmaceuticals, Inc. announced that it has received a Complete Response Letter from the U.S. Food and Drug Administration (FDA) for its KANGIO™ (bivalirudin injection), 505(b)(2) New Drug Application for a ready-to-use (“RTU”), stable liquid intravenous formulation of 5 mg/mL bivalirudin in a 50-mL vial intended for use as an anticoagulant in patients: (1) undergoing percutaneous coronary intervention (“PCI”) with use of glycoprotein IIb/IIIa inhibitor, (2) undergoing PCI with, or at risk of, heparin-induced thrombocytopenia (“HIT”) and thrombosis syndrome (“HITTS”), and/or (3) with unstable angina undergoing percutaneous transluminal coronary angioplasty (“PTCA”).
The FDA issues Complete Response Letters to communicate that their initial review of an application is complete; however, they cannot approve the application in its present form and request additional information. In its letter to Eagle, the FDA requested further characterization of bivalirudin-related substances in the drug product.
Eagle will work directly with the FDA to determine an appropriate path forward to address the comments.
