XOMA Inks $505M Servier Pact for IL-1 Inhibitor XOMA 052

XOMA Ltd. is picking up about $35 million up front in a creatively structured ex-U.S. deal with French firm Les Laboratoires Servier, which gives the Berkeley, Calif.-based biotech the chance to retain long-term upside on interleukin-1 inhibitor XOMA 052, a drug that has generated significant buzz in early stage diabetes trials.
