Vancouver, Canada; Beijing, China and Cambridge, MA, ?
Zymeworks Inc. (NYSE/TSX: ZYME), a clinical-stage biopharmaceutical company developing
multifunctional therapeutics, and BeiGene, Ltd. (Nasdaq: BGNE; HKEX: 06160), a commercialstage biopharmaceutical company focused on developing and commercializing innovative
molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced
that the two companies have entered into a strategic collaboration for the clinical development
and commercialization of Zymeworks? investigational ZW25 and ZW49 HER2-targeted
bispecific antibodies. In addition, Zymeworks granted BeiGene a license to Zymeworks'
proprietary Azymetric? and EFECT? platforms to develop and commercialize globally up to
three other bispecific antibodies using the platforms.
License and Collaboration for ZW25 and ZW49
Under the terms of the license and collaboration agreements for ZW25 and ZW49, Zymeworks
has granted BeiGene exclusive rights to develop and commercialize Zymeworks? clinical-stage
bispecific antibody candidate ZW25 and its preclinical-stage bispecific antibody drug conjugate
(ADC) ZW49 in Asia (excluding Japan), Australia, and New Zealand. BeiGene will be
responsible for all clinical development and regulatory submissions in the licensed territories. The
companies also plan to collaborate on global development of ZW25 and ZW49 in
HER2-expressing solid tumors, including gastric and breast cancer, with BeiGene enrolling
patients and contributing clinical trial data from the licensed territories. Zymeworks retains full
rights to both ZW25 and ZW49 outside of the specified countries and will continue to lead global
development of these drug candidates.
?Partnering with BeiGene was a key component of our development and commercialization
strategy for ZW25 and ZW49,? said Ali Tehrani, Ph.D., President and CEO of Zymeworks. ?This
collaboration allows Zymeworks to leverage BeiGene?s resources and expertise to accelerate the
development of our most advanced product candidates and broaden our reach globally including
in a key region of the world.?
?Zymeworks? promising candidates ZW25 and ZW49 complement our oncology pipeline and
further advance our mission to develop treatments for patients who often have limited options,?
commented Dr. Xiaobin Wu, General Manager of China and President of BeiGene, Ltd. ?Our
deep clinical experience in China is an integral part of our business development efforts, as these
trial data can be used to support global regulatory filings. We are excited by the clinical prospects
of ZW25 and ZW49 in HER2-expressing cancers.?
?At Zymeworks we are committed to developing new therapies to help address unmet medical
need on a global basis,? said Diana Hausman, MD, Zymeworks? Chief Medical Officer. ?We are
looking forward to collaborating with BeiGene and benefiting from their extensive experience in
oncology drug development in China and elsewhere. We expect that this collaboration will
accelerate the development of ZW25 and ZW49 as potential new therapies for patients with
HER2-expressing solid tumors, including gastric, breast and other cancers.?
License to Zymeworks? Azymetric and EFECT Platforms
In addition to the license and collaboration agreements for ZW25 and ZW49, Zymeworks and
BeiGene entered into a separate research and license agreement for Zymeworks? proprietary
Azymetric and EFECT platforms, under which BeiGene will have global rights to research,
develop and commercialize up to three bispecific antibody therapeutics directed to targets
selected by BeiGene. BeiGene will be responsible for all research, development, and commercial
activities under this agreement.
Financial Consideration
Under the terms of the license and collaboration agreements for ZW49 and ZW25, Zymeworks
will receive total upfront payments of US$40 million and is eligible to receive up to US$390
million in development and commercial milestone payments for both product candidates. In
addition, Zymeworks will be eligible to receive tiered royalties on future sales of ZW25 and
ZW49 in the licensed territory.
Under the terms of the research and license agreement for the Azymetric and EFECT platforms,
Zymeworks will receive an upfront payment of US$20 million and is eligible to receive up to an
aggregate of US$702 million in development and commercial milestone payments for up to three
bispecific product candidates developed under the agreement. In addition, Zymeworks will be
eligible to receive tiered royalties on future global sales of bispecific products developed by
BeiGene under the agreement.

About ZW25
ZW25 is being evaluated in a Phase 1 clinical trial in the United States and Canada. It is a
bispecific antibody, based on Zymeworks? Azymetric? platform, that can simultaneously bind
two non-overlapping epitopes of HER2, known as biparatopic binding. This unique design results
in multiple mechanisms of action including dual HER2 signal blockade, increased binding and
removal of HER2 protein from the cell surface, and potent effector function leading to
encouraging anti-tumor activity in patients. Zymeworks is developing ZW25 as a HER2-targeted
treatment option for patients with any solid tumor that expresses HER2. The FDA has granted
Orphan Drug Designation to ZW25 for the treatment of both gastric and ovarian cancers.
About ZW49
ZW49 is a novel bispecific ADC targeting two non-overlapping epitopes of HER2 resulting in
enhanced internalization and delivery of its proprietary ZymeLink cytotoxic payload. ADCs
incorporating ZymeLink have demonstrated a greater therapeutic window (range of doses that are
both efficacious and tolerable) in preclinical testing than those incorporating the commonly used
ADC payloads DM1 or MMAE. Zymeworks is developing ZW49 as a best-in-class HER2-
targeting ADC for several indications characterized by HER2 expression, especially those
patients whose tumors have progressed or are refractory to HER2-targeted agents, and those that
express lower levels of HER2 and are ineligible for treatment with current HER2-targeted
therapies. An IND application for ZW49 was recently submitted to the FDA.
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 discovery,
development, and commercialization of next-generation multifunctional biotherapeutics.
Zymeworks? suite of complementary therapeutic platforms and its fully-integrated drug
development engine provide the flexibility and compatibility to precisely engineer and develop
highly-differentiated product candidates. Zymeworks? lead product candidate, ZW25, is a novel
bispecific antibody currently being evaluated in an adaptive Phase 1 clinical trial. Zymeworks is
also advancing a deep pipeline of preclinical product candidates and discovery-stage programs in
immuno-oncology and other therapeutic areas. In addition to Zymeworks? wholly-owned
pipeline, its therapeutic platforms have been further leveraged through multiple strategic
partnerships with global biopharmaceutical companies.
