Drug Names(s): CDP 870, CDP870, certolizumab pegol

Description: Cimzia is a high-affinity humanized pegylated monoclonal antibody fragment that binds to human TNF-alpha, a key pro-inflammatory cytokine with a central role in inflammatory processes. Binding to membrane-associated and soluble TNF-alpha neutralizes the cytokine.

Certolizumab pegol does not contain a fragment crystallizable (Fc) region, which is normally present in a complete antibody, and therefore does not fix complement or cause antibody-dependent cell-mediated cytotoxicity in vitro. It does not induce apoptosis in vitro in human peripheral blood-derived monocytes or lymphocytes, nor does certolizumab pegol induce neutrophil degranulation.

Deal Structure: Cimzia was created using the license of XOMA's Bacterial Cell Expression (BCE) technology. XOMA will receive a royalty on worldwide sales of Cimzia. In August 2010, XOMA sold its royalty interest in Cimzia for $4 million to an undisclosed buyer.
