TG Therapeutics announced that enrollment has commenced in a pivotal Phase 3 trial evaluating a subcutaneous (SubQ) formulation of BRIUMVI (ublituximab-xiiy). This trial targets individuals with relapsing forms of multiple sclerosis (RMS). The study is designed to assess two different subcutaneous dosing regimens: an every-other-month schedule and a quarterly schedule. This initiative aims to provide a more convenient, self-administered treatment option for patients. BRIUMVI is currently approved in the United States and several international territories as a one-hour intravenous (IV) infusion. The development of a subcutaneous option is expected to broaden patient access and enhance the product's competitive profile by offering both IV and self-administered choices.
