Veltuzumab is a humanized monoclonal antibody targeting CD20 receptors on B lymphocytes currently under development for the treatment of non-Hodgkin’s lymphoma (NHL) and autoimmune diseases.

The Phase I/II trials of Veltuzumab, in the subcutaneous formulation, for the treatment of ITP and chronic lymphocytic leukemia (CLL) are now completed. In addition, a Phase I/II clinical trial, funded by a grant from the National Institutes of Health, is investigating the combination of Veltuzumab with yttrium-90-labeled Epratuzumab in patients with aggressive NHL.

Clinical Studies

Immune Thrombocytopenic Purpura (ITP)

Updated results from the Phase I/II trial in adult patients with chronic ITP who failed at least one standard therapy were presented at the 16th Congress of the European Hematology Association in 2011. For more information on this clinical trial, please go to

Non-Hodgkin’s Lymphoma/Chronic Lymphocytic Leukemia(NHL/CLL)

Results from the study in patients with NHL have been published in Haematologica. Information on the Phase I/II trial in patients with CLL can be obtained from

Aggressive Non-Hodgkin’s Lymphoma

The Phase I/II study combines Veltuzumab with yttrium-90-labeled Epratuzumab in patients with relapsed or refractory, aggressive non-Hodgkin's lymphoma
