XOMA Earns $35 Million Milestone Payment

November 04, 2021

EMERYVILLE, Calif. (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq: XOMA) announced that NIS793, an anti-TGFβ monoclonal antibody licensed from the Company, has advanced to the Phase 3 development stage, triggering a $35 million milestone payment from Novartis. The Phase 3 trial (NCT04935359) is designed to assess the efficacy and safety of NIS793 in combination with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel and placebo, in first-line metastatic pancreatic ductal adenocarcinoma (mPDAC). In July, Novartis announced the U.S. Food and Drug Administration has granted Orphan Drug Designation to NIS793 in combination with standard of care chemotherapy for the treatment of pancreatic cancer.

“Pancreatic cancer claims far too many lives every year, and we appreciate that Novartis chose to pursue it as the first indication for late-stage development with NIS793. We are grateful to the patients and their families who are participating in all of the NIS793 clinical studies,” stated Jim Neal, Chief Executive Officer of XOMA. “NIS793 represents one of several important assets in our partner-funded portfolio. This $35 million milestone gives us additional capital to acquire the rights to potential future milestone and royalty economics from biotech companies who can then use the capital to pursue their goal of curing a disease or condition by advancing their clinical development activities.”

Under the terms of the 2015 anti-TGFβ development and commercialization agreement with Novartis, XOMA has the potential to earn up to $410 million in additional milestone payments. Should Novartis receive regulatory approval to commercialize NIS793, XOMA will receive tiered royalties on net product sales that range from mid-single digit to low double digits.

NIS793 is an investigational compound. Efficacy and safety have not been established. There is no guarantee that NIS793 will become commercially available.
