BERKELEY, Calif., Oct. 04, 2017 (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq: XOMA ), a pioneer in the discovery, development and licensing of therapeutic antibodies, today announced it has entered into new non-exclusive license agreements with three different companies, Tizona Therapeutics, Inc., Torch Biosciences, Inc., and LakePharma, for use of XOMA’s proprietary phage display libraries for antibody discovery. Phage display libraries are powerful tools to generate human recombinant antibodies with exquisite specificity and high affinity.

“Increasing our universe of licensees to XOMA’s hallmark proprietary phage display libraries is one of our key strategic initiatives in 2017,” stated Jim Neal, Chief Executive Officer of XOMA. “These new license agreements expand our portfolio of partner-funded programs and further advance our business strategy to drive shareholder value through future milestone and royalty payments to the Company.”

Under these agreements, XOMA is eligible to receive development and regulatory milestone payments plus single-digit royalties on net sales of products. Additionally, the agreement with LakePharma, a U.S.-based biologics services company, enables it to develop its own antibodies using XOMA’s library, as well as offer the Company’s library to its broad customer base. XOMA is eligible to receive milestone and royalty payments for products developed by LakePharma and as part of its client programs.

XOMA’s premier antibody discovery platform includes three phage display libraries, which are among the largest in the world. The Company believes access to multiple libraries offers a number of benefits to its partners. Most importantly, it enables screening of libraries in parallel to increase the probability of success in finding rare and unique antibodies directed to targets of interest.
