Binding of zanidatamab-hrii with HER2 results in internalization leading to a reduction in HER2 expression of the receptor on the tumor cell surface. Zanidatamab-hrii induces complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC), and antibody-dependent cellular phagocytosis (ADCP). These mechanisms result in tumor growth inhibition and cell death in vitro and in vivo. In the United States, Ziihera is indicated for the treatment of adults with previously treated, unresectable or metastatic HER2-positive (IHC 3+) biliary tract cancer (BTC), as detected by an FDA-approved test.<sup>1<\/sup> The FDA granted accelerated approval for this indication based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).<sup>1<\/sup><\/p>\n<p>Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is being developed by\u202fJazz\u202fand BeOne under license agreements from Zymeworks, which first developed the molecule.<\/p>\n<p>The FDA granted two Breakthrough Therapy designations for zanidatamab&#8217;s development: one as a single agent for previously treated HER2 gene-amplified BTC, and one in combination with standard-of-care chemotherapy for first-line HER2+ locally advanced or metastatic GEA. The FDA also granted 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. Additionally, zanidatamab has received Orphan Drug designations from the FDA for the treatment of BTC, gastric (including gastroesophageal junction) cancer, and esophageal cancer, as well as Orphan Drug designations from the European Medicines Agency for the treatment of BTC, gastric\/gastroesophageal junction cancer and oesophageal cancer.<\/p>\n<p>The full\u202fU.S.\u202fPrescribing Information for\u202fZiihera, including BOXED Warning, is available at: <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=XQGvy-8kXgQJA7YqqRXEFJsN7FDvX0dZup4FyStlpZjpv53BeswRMp2aN4z8ESy5XyomNfZ5uC_qSyaI1sRz5xO_KMv9W7ZAbO5YRcQn1e6LzRdYISBCt_UhkGAOYbINHDV8hStnofoKH93WgU2liy04JP10NltGlJ6Hg7H6CYM=\" rel=\"nofollow\" target=\"_blank\">https:\/\/pp.jazzpharma.com\/pi\/ziihera.en.USPI.pdf<\/a><\/p>\n<p>\n        <strong>About Zymeworks Inc. <\/strong>\n      <\/p>\n<p>Zymeworks is a global biotechnology company managing a portfolio of licensed healthcare assets and developing a diverse pipeline of novel, multifunctional biotherapeutics to improve the standard of care for difficult-to-treat diseases, including cancer, inflammation, and autoimmune disease.
