Amgen And Allergan Submit Biologics License Application For ABP 798, Biosimilar Candidate To Rituxan® (rituximab), To U.S. Food And Drug Administration

Filing for ABP 798 Supported by Two Comparative Clinical Studies

THOUSAND OAKS, CA, USA I December 19, 2019 I Amgen (NASDAQ:AMGN) and Allergan plc. (NYSE:AGN) today announced the submission of a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for ABP 798, a biosimilar candidate to Rituxan® (rituximab). Amgen and Allergan are collaborating on four oncology biosimilar medicines, two of which have already been approved by the FDA.

"The U.S. filing for ABP 798 marks an important milestone for Amgen, as it affirms our commitment to providing high quality biosimilars that offer more life-altering biological treatment options and contribute to the sustainability of healthcare systems," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "We look forward to working with the FDA to bring ABP 798 to market."

ABP 798 has been developed as a biosimilar candidate to Rituxan. Rituxan is a CD20-directed cytolytic antibody that has been approved in many regions for, among other things, the treatment of adult patients alone or in combination with chemotherapy for non-Hodgkin's lymphoma, in combination with fludarabine and cyclophosphamide for chronic lymphocytic leukemia, granulomatosis with polyangiitis and microscopic polyangiitis with glucocorticoids. 

"We are excited about the progress that we've made to date through our partnership with Amgen, which includes the launch of the first two oncology therapeutic biosimilars in the U.S.," said David Nicholson, Ph.D., chief research and development officer at Allergan. "With ABP 798, we look forward to the opportunity to continue to provide additional treatment options to patients suffering from serious illnesses."

The BLA submission includes analytical, pharmacokinetic and clinical data, as well as pharmacology and toxicology data generated in two clinical studies. The results of these studies confirmed no clinically meaningful differences between ABP 798 and Rituxan.

Amgen has a total of 10 biosimilars in its portfolio, four of which have been approved in the U.S. and three that are approved in the European Union (EU).

About ABP 798
ABP 798 has been developed as a biosimilar candidate to Rituxan. Rituxan is an anti-CD20 monoclonal antibody that has been approved in many regions for the treatment of, among other things, adult patients alone or in combination with chemotherapy for non-Hodgkin's lymphoma, in combination with fludarabine and cyclophosphamide for chronic lymphocytic leukemia, granulomatosis with polyangiitis and microscopic polyangiitis with glucocorticoids. The active ingredient of ABP 798 is a monoclonal antibody that has the same amino acid sequence as Rituxan.

About the Amgen and Allergan Collaboration
In December 2011, Amgen and Allergan plc. (then Watson Pharmaceuticals, Inc.) formed a collaboration to develop and commercialize, on a worldwide basis, four oncology antibody biosimilar medicines. This collaboration reflects the shared belief that the development and commercialization of biosimilar products will not follow a pure brand or generic model and will require significant expertise, infrastructure, and investment to ensure safe, reliably supplied therapies for patients. Under the terms of the agreement, Amgen assumes primary responsibility for developing, manufacturing and initially commercializing the oncology antibody products.
