Tofidence™ (tocilizumab-bavi – Biogen) intravenous (IV) injection was approved on Sept. 29, 2023, by the U.S. Food and Drug Administration (FDA) as the first biosimilar for the IV form of Genentech’s Actemra®. It is indicated for treating active, moderate to severe cases of rheumatoid arthritis (RA) in adults, and polyarticular juvenile idiopathic arthritis (PJIA) and systemic juvenile idiopathic arthritis (SJIA) in patients who are as young as two years old. For adults who have RA, the recommended once-monthly dose is 4mg/kg, which can be increased to 8mg/kg if needed. For children who weigh less than 30kg (66 pounds) the dose for PJIA is 10mg/kg; for SJIA 12mg/kg. For those who weigh more, the pediatric dose is 8mg/kg for either juvenile condition. A boxed warning cautions that using any tocilizumab drug may increase the risk of opportunistic bacterial, fungal, viral, or other infections. Before tocilizumab is started and during treatment with it, patients should be tested for tuberculosis (TB). Launch date and pricing are not yet available for Tofidence.
