Daiichi Sankyo Selects Lead Candidate Built on Zymeworks’ Azymetric™ Bispecific Platform
・One of three bispecific immuno-oncology therapeutics being developed under the two companies’ collaboration agreements
・Zymeworks to receive US$3.5 million commercial license payment from Daiichi Sankyo
Vancouver, Canada, Tokyo, Japan and Basking Ridge, NJ (April 25, 2019)– Zymeworks Inc. (NYSE/TSX: ZYME), a clinical-stage biopharmaceutical company developing multifunctional biotherapeutics, and Daiichi Sankyo Company, Limited (“Daiichi Sankyo”) announced today that Daiichi Sankyo has exercised its option for a commercial license to a proprietary immuno-oncology bispecific built on Zymeworks’ Azymetric™ and EFECT™ platforms. Zymeworks will receive a US$3.5 million payment based on Daiichi Sankyo’s selection of the first of up to three lead product candidates under its collaboration agreements with Zymeworks.
“This is another example of how our Azymetric platform can facilitate the rapid selection and development of bispecific antibody candidates for our pharmaceutical partners,” said Ali Tehrani, Ph.D., President and CEO of Zymeworks. “We are thrilled to see Daiichi Sankyo move this novel therapeutic program into late-stage preclinical development. This is an important step forward towards our shared goal of improving the standard of care for patients with cancer.”
“Our partnership with Zymeworks has allowed us to develop therapeutic candidates based on complex mechanisms of action such as immune cell engagement,” said Antoine Yver, M.D., M.Sc., Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. “Through this partnership, we have identified a novel bispecific therapeutic that we are excited to be advancing towards the clinic. We look forward to continuing our strong partnership with Zymeworks to develop novel therapeutic options for patients with cancer worldwide.”
Under the terms of the 2016 cross-licensing and collaboration agreement, Zymeworks granted Daiichi Sankyo a license to Zymeworks’ Azymetric™ and EFECT™ platforms to develop a bispecific antibody therapeutic for which Zymeworks is eligible to receive further clinical and commercial milestone payments of up to US$143.4 million, as well as up to double-digit tiered royalties on global product sales. Additionally, Zymeworks obtained a license to certain immuno-oncology antibodies from Daiichi Sankyo, with the right to research, develop, and commercialize multiple bispecific products globally in exchange for royalties on global product 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.
About the EFECT™ Platform
The EFECT platform is a library of antibody Fc modifications engineered to modulate the activity of the antibody-mediated immune response, which includes both the up- and down-regulation of effector functions. This platform, which is compatible with traditional monoclonal as well as Azymetric bispecific antibodies, further enables the customization of therapeutic responses for different diseases.
About Zymeworks Inc.
Zymeworks is a clinical-stage biopharmaceutical company dedicated to the development of next-generation multifunctional biotherapeutics. The Company’s suite of therapeutic platforms and its fully integrated drug development engine enable precise engineering of highly differentiated product candidates. Zymeworks’ lead clinical candidate, ZW25, is a novel Azymetric™ bispecific antibody currently in Phase 2 clinical development. The Company’s second clinical candidate, ZW49, is a bispecific antibody-drug conjugate currently in Phase 1 clinical development and combines the unique design and antibody framework of ZW25 with Zymeworks’ proprietary ZymeLink™ cytotoxic payload. Zymeworks is also advancing a deep preclinical pipeline in immuno-oncology and other therapeutic areas. In addition, its therapeutic platforms are being leveraged through multiple strategic partnerships with eight global biopharmaceutical companies. For more information, visit: www.zymeworks.com.
