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.
Jazz Pharmaceuticals plc in-licensed regional rights to Zymeworks Inc.’s HER2- targeted bispecific antibody zanidatamab in a deal potentially worth $1.76 billion, plus royalties. Jazz wants to expand its oncology portfolio with the deal, which covers the U.S., Europe, Japan and all other territories except Asia Pacific markets previously licensed by Zymeworks to Beigene Ltd.
Zymeworks Inc.’s business update – which included a new, potential $891 million deal for multispecific antibody drugs with longtime partner Merck & Co. Inc. – drew mixed reviews from Wall Street, especially with regard to phase I prospect ZW-49.
