XOMA Earns $10 Million Milestone Payment as Another of its Licensed Assets Advances into Clinical Development

BERKELEY, Calif., May 18, 2017 -- XOMA Corporation (Nasdaq:XOMA), a pioneer in the discovery and development of therapeutic antibodies, today announced it has earned a $10 million milestone payment, reflecting the clinical advancement of an asset the Company licensed to one of its pharmaceutical partners. 

“Our corporate strategy is to drive shareholder value by combining revenue from our portfolio of collaborator-funded programs with a lean cost structure,” stated Jim Neal, Chief Executive Officer of XOMA. “This $10 million milestone payment is the first of a potential $40 million we could receive from our portfolio of partnerships over the next 36 months. As these milestones are received, our belief is shareholders will begin to see XOMA transition to a cash flow positive company.”   

Similar to this program, XOMA has over 20 additional clinical and preclinical programs that are fully funded by partners across the biotech and pharmaceutical landscape. Each of those programs, as well as several internal programs available to be partnered, are capable of adding to the anticipated growth in milestone payments and royalty revenue streams over time.

As previously announced, XOMA will hold its annual meeting of stockholders today, May 18, 2017, at 9:00 a.m. PT (12:00 p.m. ET), which will be held virtually via live webcast. Jim Neal, Chief Executive Officer of XOMA, will host the meeting and provide a corporate update. The presentation slides and webcast can be accessed via the Investors and Media section of XOMA's website at http://investors.xoma.com/events.cfm.

About XOMA Corporation

XOMA has an extensive portfolio of products, programs, and technologies that are the subject of licenses the Company has in place with other biotech and pharmaceutical companies. Many of these licenses are the result of the Company’s pioneering efforts in the discovery and development of antibody therapeutics. There are more than 20 such programs that are fully funded by partners and could produce milestone payments and royalty payments in the future. In order to maximize its value in a licensing transaction, XOMA continues to invest in X358, an allosteric monoclonal antibody that reduces insulin receptor activity, as the antibody could have a major impact on the treatment of hyperinsulinism.
