A potentially $1.76 billion oncology deal created a little more than three years ago between partners Jazz Pharmaceuticals plc and Zymeworks Inc. now has a more solid direction. New and positive top-line results for the phase III Herizon-GEA-01 study of the HER2-targeted bispecific antibody zanidatamab in locally advanced or metastatic gastroesophageal adenocarcinoma (GEA) moved the stock and expectations for both companies.
The U.S. FDA has cleared Zymeworks Inc.’s IND application for ZW-251, a novel glypican-3 (GPC3)-targeted antibody-drug conjugate (ADC) incorporating the company’s proprietary topoisomerase 1 (TOPO1) inhibitor payload, ZD-06519, for the treatment of hepatocellular carcinoma (HCC).
Chronic obstructive pulmonary disease (COPD) is a prevalent and heterogeneous respiratory disorder with limited effective treatments. IL-33 and IL-4Rα are key mediators of airway inflammation in COPD and hence represent potential therapeutic targets.
Researchers from Zymeworks Inc. recently reported preclinical data for ZW-220, an antibody-drug conjugate (ADC) consisting of humanized IgG1 monoclonal antibody targeting sodium-dependent phosphate transport protein 2B (SLC34A2, NaPi2b) conjugated to a topoisomerase I inhibitor, being developed for the treatment of cancer.
Researchers from Zymeworks Inc. presented preclinical data for the novel glypican-3 (GPC3)-targeting antibody-drug conjugate (ADC), ZW-251, being developed as an anticancer agent.
Zymeworks Inc. has received IND clearance from the FDA for ZW-191, the company’s novel folate receptor-α (FRα)-targeted topoisomerase I (TOPO1) inhibitor antibody-drug conjugate (ADC). Clinical development is set to begin this year, with filings to initiate studies outside the U.S. to be made in the second half of this year.
Zymeworks Inc. has obtained IND clearance from the FDA for ZW-171, a novel T-cell targeting bispecific antibody for mesothelin (MSLN)-expressing cancers. Clinical development will begin this year, and additional applications will be filed in the second half of the year seeking trial clearances in other territories.
Zymeworks Inc. has announced that its current R&D priority is to progress its differentiated portfolio of antibody-drug conjugates (ADCs) into clinical studies this year and next.
HER2-targeting bispecific antibody zanidatamab, in development by Jazz Pharmaceuticals plc and Zymeworks Inc., produced better antitumor responses than current standard of care when used as a second-line treatment for biliary tract cancer (BTC) in a pivotal phase IIb study, bringing it closer to becoming the first therapy to target HER2-expressing BTC.
