A Bold
Approach

Ublituximab (TG-1101) is an investigational glycoengineered monoclonal antibody that targets a unique epitope on CD20-expressing B cells. When ublituximab binds to the B cell it triggers a series of immunological reactions (including antibody-dependent cellular cytotoxicity [ADCC] and complement dependent cytotoxicity [CDC]), leading to destruction of the cell. Additionally, ublituximab is uniquely designed, to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, has been shown to enhance the potency of ublituximab, especially the ADCC activity.

Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of B-cell malignancies and autoimmune disorders, both diseases driven by the abnormal growth or function of B cells.

Ublituximab is being evaluated in pivotal and early phase clinical trials for patients with NHL, CLL, and relapsing forms of multiple sclerosis (RMS).
