DUBLIN and VANCOUVER, Oct. 19, 2022 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) and Zymeworks Inc. (NYSE: ZYME) today announced that Jazz and Zymeworks' subsidiary, Zymeworks BC Inc., have entered into an exclusive licensing agreement under which Jazz will acquire development and commercialization rights to Zymeworks' zanidatamab across all indications in the United States, Europe, Japan and all other territories except for those Asia/Pacific territories previously licensed by Zymeworks.
"Zanidatamab is a novel HER2-targeted bispecific antibody with biparatopic binding and the potential to transform the current standard of care in multiple HER2 expressing cancers," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "This agreement reflects Jazz's strategic focus on opportunities where we can not only apply advanced technologies to address critical unmet patient needs, but where we can also leverage Jazz's existing integrated capabilities and global infrastructure to commercialize efficiently. Zanidatamab has the potential to deliver significant long-term value and meaningfully contribute to Vision 2025 as we aim to deliver at least five novel therapies to patients by the end of the decade. We are pleased to expand our growing oncology pipeline with a late-stage program, and today's announcement further demonstrates our commitment to delivering novel oncology therapies."
"In partnering with Jazz, we are thrilled to be working with a leading global biopharmaceutical team that brings a wealth of development and commercial experience in oncology and shares our vision and passion for working hard every day to improve outcomes for cancer patients around the world," said Kenneth Galbraith, Chair & CEO of Zymeworks. "Zymeworks and Jazz are committed to advancing the development of zanidatamab as rapidly as possible, with the potential to provide a foundational HER2-targeted therapy for patients with difficult-to-treat cancers who currently have limited treatment options."
Zanidatamab, a HER2-targeted bispecific antibody with novel mechanisms of action, has demonstrated compelling anti-tumor activity in several HER2-expressing cancers, both as monotherapy and in combination with chemotherapy and other agents. Zanidatamab is currently in pivotal trials as a second-line treatment for HER2-expressing biliary tract cancer (BTC) and as a first-line treatment for HER2-positive gastroesophageal adenocarcinoma (GEA). In BTC, where no HER2-targeted therapies are currently approved, the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for zanidatamab, positioning it as a potential first-in-class therapy. In GEA, based on Phase 2 data, zanidatamab in combination with chemotherapy has the potential to be a best-in-class therapy.
Zanidatamab is based on Zymeworks' Azymetric™ platform and can simultaneously bind two non-overlapping epitopes of HER2, which is known as biparatopic binding. This innovative design results in multiple novel mechanisms of action including dual HER2 signal blockade, enhanced binding and removal of HER2 protein from the cell surface, and potent effector function leading to encouraging antitumor activity in patients.
FDA has granted Breakthrough Therapy designation for zanidatamab in patients with previously treated HER2 gene-amplified BTC, and two Fast Track designations for zanidatamab, one as a single agent for refractory BTC and one in combination with standard of care chemotherapy, for first-line GEA. These designations mean zanidatamab is eligible for Accelerated Approval, Priority Review and Rolling Review, as well as FDA guidance on an efficient drug development program. Zanidatamab has also received Orphan Drug designations from FDA for the treatment of biliary tract and gastric cancers, as well as Orphan Drug designation from the European Medicines Agency for the treatment of gastric cancer.
Under the terms of the agreement, Jazz will receive an exclusive license to develop and commercialize zanidatamab in the United States, Europe, Japan and all other territories except for those Asia/Pacific territories that Zymeworks previously licensed to BeiGene, Ltd. Zymeworks is eligible to receive a $50 million upfront payment, following receipt of the clearance relating to the United States Hart-Scott Rodino Antitrust Improvements Act of 1976 (such clearance, the "HSR Clearance"), and should Jazz decide to continue the collaboration following readout of the top-line clinical data from HERIZON-BTC-01, a second, one-time payment of $325 million. Zymeworks is also eligible to receive up to $525 million upon the achievement of certain regulatory milestones and up to $862.5 million in potential commercial milestone payments, for total potential payments of up to $1.76 billion. Pending approval, Zymeworks is eligible to receive tiered royalties between 10% and 20% on Jazz's net sales.
Closing of the agreement is subject to expiration or termination of the waiting period under the Hart-Scott-Rodino Act of 1976. The transaction is expected to close within the 2022 calendar year.
Zymeworks management will host a conference call and webcast for investors and analysts on October 19, 2022, at 8:00 a.m. ET. Interested parties should refer to the separate press release issued by Zymeworks for additional details.
Zanidatamab 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 antitumor activity in patients. Zymeworks is developing zanidatamab in multiple Phase 1, Phase 2 and pivotal clinical trials globally as a targeted treatment option for patients with solid tumors that express HER2.
About Biliary Tract Cancers
Biliary tract cancers (BTC), including gallbladder cancer and cholangiocarcinoma, account for approximately 3% of all adult cancers and are often associated with a poor prognosis1. Globally, more than 210,000 people are diagnosed with BTC every year2 and most patients (> 65%) are diagnosed with tumors that cannot be removed surgically. The human epidermal growth factor receptor 2 (HER2) is a well-validated target for anti-cancer therapy. About 5% to 19% of patients with BTC have tumors that express HER23 and may be positioned for potential benefit from HER2-targeted therapy. Currently no HER2-targeted therapy has been approved for the treatment of BTC.
About Gastroesophageal Adenocarcinoma
Gastroesophageal adenocarcinoma (GEA) is the fifth most common cancer worldwide and approximately 20% of patients are HER2–positive. HER2–positive GEA has high morbidity and mortality, and patients are urgently in need of new treatment options.
