CDP 571 [anti-TNF monoclonal antibody, BAY 103356, BAY W 3356, Humicade] is a recombinant humanised antibody directed against tumour necrosis factor (TNF). CDP 571 has an advantage over the mouse/human chimera anti-TNF-alpha antibody, nerelimomab, in that it is suitable for multiple dosing as it is not so immunogenic. Celltech constructed CDP 571 by grafting the section of mouse antibody that recognises TNF onto a human IgG4 antibody. In the third quarter of 1999, Celltech merged with Chiroscience to form Celltech Chiroscience. In January 2000, Medeva was merged into Celltech Chiroscience, which was renamed as Celltech Group. The research division of Celltech Group is now called Celltech R&D (formerly Celltech Chiroscience Discovery) and the manufacturing and marketing division is called Celltech Pharmaceuticals (formerly Celltech Medeva Pharma). Celltech has completed two phase III trials, involving around 670 patients with moderate-to-severe Crohn's disease; however, both these trials failed to meet their primary endpoints. Biogen and Celltech group will review the scope of their collaboration following additional analysis of the phase III data and discussions with regulatory authorities. The Celltech Group intends to devote significant resources towards enhancing the capability of Celltech Pharmaceuticals to market CDP 571 and other new drugs (such as CDP 860 and CDP 870) as specialised hospital products. Phase II trials were underway in the United Kingdom for use of the drug in the treatment of type 2 diabetes mellitus. However, these trials have also been discontinued. Celltech Group is no longer developing CDP 571 for septic shock, based on negative results with the related compound nerelimomab. The compound was in phase III trials for septic shock in France, Belgium, the United Kingdom, Germany and the US. Celltech also plans to investigate the use of CDP 571 in psoriasis via a collaboration with Biogen (USA). In January 2002, AFX (Agence France-Presse and the Financial Times Group) reported that analysts at Morgan Stanley have forecast Humicade trade mark to reach sales of 250 million US dollars in 2008--at that time, the market value for anti-TNF products to treat rheumatoid arthritis and Crohn's disease will exceed 4 billion US dollars, according to Morgan Stanley.
