ATHENEX Announces the Launch of the Novel Non-Frozen Ready-To-Use Bivalirudin

Athenex, Inc. (NASDAQ: ATNX), a leading global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer, today announced the launch of a Ready-to-Use (RTU) Bivalirudin Injection through its subsidiary Athenex Pharmaceutical Division (APD). Bivalirudin RTU Injection is indicated for use as an anticoagulant in patients undergoing percutaneous coronary intervention (PCI), including patients with heparin-induced thrombocytopenia and heparin-induced thrombocytopenia and thrombosis syndrome.

APD, a supplier of high-quality specialty injectable products to US hospitals, licensed the marketing rights to the NDA from MAIA Pharmaceuticals, a Princeton, NJ based specialty pharmaceutical company.

Bivalirudin RTU Injection is available to order from APD in a 250mg/50mL (5mg/mL concentration) Piggyback Vial.

Per IQVIA sales data, the Bivalirudin Injection market in the United States exceeds $67 million annually.

“We are delighted to introduce a unique RTU Bivalirudin Injection that does not require frozen storage into the US hospital market,” said Jeffrey Yordon, Athenex’s Chief Operating Officer. “The launch of this innovative product underlines the unique ability of Athenex to work quickly and collaboratively to bring much needed products to our customers. We’d like to thank our partners at MAIA for matching our agility, enabling our speed to market, and supporting our unwavering commitment to delivering high-quality products that can help address our customers’ ongoing needs.”

Srikanth Sundaram, Ph.D., President of MAIA, added, “We are thrilled with the launch of MAIA’s NDA product by the seasoned and exceptional team at Athenex. Bivalirudin RTU Injection, which does not need reconstitution and further dilution unlike the lyophilized version, essentially eliminates the drug preparation process. By avoiding potential errors in the drug preparation and administration process and associated adverse events, its use offers benefits to the patient.”

Athenex’s products emphasize quality and can help to enhance patient safety. Athenex’s AccuraSEE℠ Packaging and Labeling, a proprietary, patent-pending and highly differentiated approach to product packaging and labeling, features a unique label design for every product to give caregivers accurate information and help to reduce the risk of medication errors.
