XOMA Earns $3 Million Milestone Payment from its License Agreement with Nanotherapeutics

BERKELEY, Calif., Sept. 11, 2017 -- XOMA Corporation (Nasdaq:XOMA), a pioneer in the discovery, development and licensing of therapeutic antibodies, today announced it has earned a $3 million milestone payment related to the clinical advancement of an anti-botulism product candidate the Company licensed to Nanotherapeutics, Inc. in 2015. The product candidate was originally discovered and engineered with XOMA’s antibody platform and expertise. Nanotherapeutics now is developing the product, which is intended to protect against the harmful and even deadly effects of botulinum neurotoxins that could be deployed by bioterrorists or other enemies.

Beyond representing both a near- and long-term cash generating event, the milestone more importantly indicates that the product is advancing towards later-stage development. If the product candidate advances from its current stage of development to production and stockpiling by governmental agencies, XOMA is eligible to receive a 15% royalty on net sales. 

“We are rapidly advancing our corporate strategy to drive shareholder value by combining revenues from our portfolio of partner-funded programs with a lean cost structure,” stated Jim Neal, Chief Executive Officer of XOMA. “This milestone event reinforces the strength of our business model. The wide-range of XOMA assets under development by our partnerships has the potential to generate near- and long-term financial benefits.”   

In September 2017, the Company received an initial cash payment of $250,000 related to the milestone. The remaining amounts of the milestone payment will be received in monthly payments over the next eleven months.
