Visilizumab (tentative trade name Nuvion, PDL BioPharma Inc.) is a humanized monoclonal antibody. It is being investigated for use as an immunosuppressive drug in patients with ulcerative colitis and Crohn's disease. Visilizumab binds to the CD3 receptor on certain activated T cells without affecting resting T cells. It is currently under clinical studies for the treatment of ulcerative colitis and Crohn's disease.[1]

PDL BioPharma, Inc. canceled production of visilizumab following its Phase II/III clinical trials, citing its inefficacy and poor safety profile compared to other drugs on the market as the major reasons.[2] Nevertheless, clinical trials continue for various diseases like multiple myeloma[3] and diabetes mellitus type 1[4][5] as of July 2009.

Visilizumab has also been radiolabelled with technetium-99m for imaging T cells.[6]
