XOMA Announces Pre-Clinical and Clinical Progress On HCD122
Monday December 11, 10:40 am ET
ORLANDO, Fla., Dec. 11, 2006 (PRIME NEWSWIRE) -- At the annual meeting of the American Society of Hematology (ASH), XOMA Ltd. (NASDAQ:XOMA - News), along with Novartis, announced pre-clinical and preliminary Phase 1 clinical trial results of the use of the experimental drug HCD122, an anti-CD-40 monoclonal antibody, in the treatment of patients with relapsed and refractory Multiple Myeloma (MM) and Chronic Lymphocytic Leukemia (CLL). The development of HCD122 (formerly known as CHIR-12.12) began in 2004 as part of XOMA's collaboration with Chiron Corporation, which Novartis acquired earlier this year. Chiron is now known as Novartis Vaccines and Diagnostics, Inc.
``We are pleased to see continued progress in the clinical program for CLL and MM. We are also very encouraged with the results in preclinical animal models of lymphoma that showed a very favorable profile for HCD122,'' said Jack Castello, chairman of the board, president, and chief executive officer of XOMA. ``We continue to believe this is a very promising drug and expect to expand clinical development into other indications during 2007.''
About HCD122
HCD122 is a fully human antagonist anti-CD40 monoclonal antibody for treatment of B-cell malignancies. As shown in vitro in cell lines, in vivo in animal models and ex vivo in patient cells, HCD122 has a dual mode of action: (1) This antibody binds to tumor cells that express CD40 and prevents CD40 ligand-mediated growth and survival of malignant B cells; and (2) HCD122 induces antibody-dependent cellular cytotoxicity (ADCC), killing CD40 expressing tumor cells by immune effector cells. This dual mechanism of action makes HCD122 a drug candidate with potential for the treatment of B-cell malignancies.
