  • First of ten potential products built on Zymeworks’ proprietary AzymetricTM platform
  • Zymeworks to receive US$7.5 million commercial license payment

 

VANCOUVER, British Columbia--(BUSINESS WIRE)-- Zymeworks Inc. (NYSE/TSX: ZYME), a clinical-stage biopharmaceutical company developing multifunctional therapeutics, today announced that its global biopharma partner Celgene Corporation has selected a lead therapeutic candidate in oncology for further development and exercised its option to a commercial license under the companies’ 2014 Azymetric collaboration and licensing agreement. Zymeworks’ proprietary Azymetric technology platform enables the rapid development of bispecific and multifunctional therapeutics with broad potential for the treatment of cancer, inflammation, and infectious disease. Zymeworks will receive a US$7.5 million payment as a result of Celgene’s exercise of its option to a commercial license.

“Celgene’s first selection of a lead bispecific antibody candidate using the Azymetric platform underscores their dedication to our partnership and the comprehensive utility of our industry-leading technologies,” said Ali Tehrani, Ph.D., President and Chief Executive Officer at Zymeworks. “Celgene’s progress, alongside that of Lilly, Daiichi, and Merck, which we announced earlier this year, advances our goal of enabling innovative medicines for patients around the world.”

Celgene is one of five global biopharmaceutical companies that has expanded their collaboration agreements with Zymeworks to increase the number of potential products commercialized based on the Azymetric platform. Under the terms of the original 2014 agreement, Zymeworks granted Celgene a license to research, develop, and commercialize up to eight bispecific antibodies, and in 2018, the companies increased the number of potential products to ten. For each of the up to ten products, Zymeworks is eligible to receive up to US$164 million comprised of a licensing fee and development and commercial milestones in addition to royalties on worldwide sales.

About the Azymetric™ Platform

The Azymetric platform enables the transformation of monospecific antibodies into bispecific antibodies, giving the antibodies the ability to simultaneously bind two different targets. Azymetric bispecific technology enables the development of multifunctional biotherapeutics that can block multiple signaling pathways, recruit immune cells to tumors, enhance receptor clustering degradation, and increase tumor-specific targeting. These features are intended to enhance efficacy while reducing toxicities and the potential for drug resistance. Azymetric bispecifics have been engineered to retain the desirable drug-like qualities of naturally occurring antibodies, including low immunogenicity, long half-life, and high stability. In addition, they are compatible with standard manufacturing processes with high yields and purity, potentially significantly reducing drug development costs and timelines.
