Amneal Enters U.S. Biosimilars Market With Approval of RELEUKOTM (filgrastim-ayow)

– First of three Amneal biosimilars expected for U.S. approval and launch in 2022

BRIDGEWATER, N.J.–(BUSINESS WIRE)–Amneal Pharmaceuticals, Inc. (NYSE: AMRX) (“Amneal” or the “Company”) today announced the U.S. Food and Drug Administration (FDA) approval of the Biologics License Application (BLA) for filgrastim-ayow, a biosimilar referencing Neupogen^®. The product will be marketed under the proprietary name RELEUKO^TM.

RELEUKO^TM was developed in collaboration with Kashiv Biosciences, LLC located in Chicago, Illinois. It is used to treat neutropenia (low neutrophils which are a type of white blood cells that fight infection) which is commonly experienced by patients undergoing chemotherapy. Amneal expects to launch RELEUKO^TM in the third quarter of 2022, along with a full patient support program.

The Company is planning for a pegfilgrastim biosimilar referencing Neulasta^® and a bevacizumab biosimilar referencing Avastin^® to launch in 2022. Both are being reviewed by the FDA.

“The U.S. approval of our first biosimilar is a very significant milestone for Amneal. Biosimilars represent the next wave of providing access to affordable medicines in the U.S. We are building a global biosimilars business by leveraging partner assets to start and then leveraging our own key capabilities over time. Our goal is to become a meaningful long-term player in biosimilars,” said Chirag and Chintu Patel, Co-Chief Executive Officers.

“It is a proud moment for the Kashiv Biosciences team and our partners at Amneal to have our first biosimilar, RELEUKO™, approved by the U.S. FDA. Kashiv is one of a few domestic companies to manufacture and launch a biosimilar in the United States. Kashiv aims to continue bringing high quality biosimilars to the global markets over the coming years. I would like to extend a humble thank you to our highly talented team, without whom this would not have been possible,” said Dr. Chandramauli Rawal, Chief Operating Officer for Kashiv.

According to IQVIA®, U.S. annual sales for filgrastim for the 12 months ended December 2021 were $407 million, of which $275 million represents biosimilar sales.

• To decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti- cancer drugs associated with a significant incidence of severe neutropenia with fever.
• To reduce the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML).
