4.5 (2) TG Therapeutics has expanded its contract with Samsung Biologics to manufacture ublituximab, an investigational therapy for relapsing forms of multiple sclerosis (MS). “Samsung is the global leader in biologics manufacturing and we are happy to have them as our partner as we look forward to the potential commercialization of ublituximab across both oncology and autoimmune indications,” Michael S. Weiss, executive chairman and CEO of TG Therapeutics, said in a press release. Ublituximab is an antibody designed to prevent B-cells from triggering the inflammation that causes nerve cell damage in MS. It does so by targeting a protein called CD20 that’s found on the B-cell surface.
