– Takeda regains a majority of XOMA Royalty’s royalty interest in mezagitamab (TAK-079) –– XOMA Royalty will be entitled to payments based on a share of milestones and royalties associated with nine development-stage assets held within Takeda’s externalized assets portfolio – EMERYVILLE, Calif., Dec. 30, 2025 (GLOBE NEWSWIRE) -- XOMA Royalty Corporation (NASDAQ: XOMA), the biotech royalty aggregator, announced today it has amended its collaboration, originally established in 2006, with Takeda through a strategic royalty share transaction. Takeda’s royalty and milestone payment obligations to XOMA Royalty related to mezagitamab will be reduced, and XOMA Royalty will receive payments based on low to mid-single-digit royalties and milestones across a basket of nine development-stage assets that are held within Takeda’s externalized assets portfolio. “We continue to find ways to expand and diversify our royalty and milestone portfolio through creative transactions that are beneficial to both parties,” stated Brad Sitko, Chief Investment Officer of XOMA Royalty. “Takeda and XOMA Royalty have a long history of collaboration. By amending our collaboration, we are able to return a portion of our mezagitamab economics to Takeda, while also expanding and diversifying XOMA Royalty’s portfolio across several interesting early- and late-stage programs.” MezagitamabPrior to amending the collaboration, XOMA Royalty held a mid-single digit royalty and $16.25 million in potential milestones associated with mezagitamab. Going forward, XOMA Royalty will retain a low single-digit royalty entitlement on mezagitamab and up to $13.0 million in milestones. Development-Stage Assets from Takeda’s Externalized Assets Portfolio Osavampator Neurocrine Biosciences is developing osavampator, a potential first-in-class, investigational alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) positive allosteric modulator (PAM) for patients who have inadequate response to treatment for major depressive disorder (MDD). Volixibat Mirum Pharmaceuticals is developing volixibat, a minimally absorbed, orally administered investigational therapy designed to selectively inhibit ileal bile acid transporter (IBAT), for primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC).
