California, USA-based therapeutic antibody firm XOMA (Nasdaq: XOMA) says it has sold its royalty interest in Cimzia (certolizumab pegol), which is marketed by Belgian drugmaker UCB (BB; UCB), for $4 million to an undisclosed buyer.
The manufacture of Cimzia is covered by a license to XOMA's Bacterial Cell Expression technology. The licensed US patents will expire in 2014. Cimzia is a pegylated antibody fragment that targets tumor necrosis factor alpha. It is approved in the US to treat Crohn's disease and rheumatoid arthritis. In the first six months of this year Cimzia, which has only recently been launched, generated sales of 83 million euros ($105.9 million), up 240%, for UCB.
Cimzia is UCB's most important new product. Based on a consensus sales forecast of $821 million by 2014, the drug is worth $2.26 billion to the firm, according to EvaluatePharma's NPV Analyzer.
