Ublituximab (TG-1101) is a novel glycoengineered anti-CD20 monoclonal antibody
Ublituximab (TG-1101) is a monoclonal antibody that targets CD20 positive B-cells, a component of the body’s immune system. When it attaches to the B-cell it triggers immune reactions (including antibody-dependent cellular cytotoxicity, ADCC, and antibody-dependent cellular phagocytosis that result in the death of the targeted B-cell). Anti-CD20 monoclonal antibodies have proven efficacious in the treatment of diseases in which B-cells have become malignant or overactive, including cancers such as Non-Hodgkin Lymphoma (NHL) and Chronic Lymphocytic Leukemia (CLL) and autoimmune related diseases such as Multiple Sclerosis (MS), Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus(SLE).
While ublituximab is a novel patented molecule, it’s mechanism of action is similar to the approved anti-CD20 monoclonal antibodies. The innovation of ublituximab is that it has been bioengineered to remove certain sugar molecules from the anti-CD20 antibody, which are naturally occurring. By removing the sugar molecules in a process called glycoengineering, we have enhanced the potency of ublituximab with data showing 50-100x greater activity than non-bioengineered anti-CD20 antibodies.
Ublituximab demonstrated encouraging activity as a B-cell depleting agent in early trials, and is now being studied in registration directed clinical trials for patients with CLL and NHL as well as patients with MS.
