Overview
BAT1806 is a biosimilar tocilizumab developed by Bio-Thera Solutions and Biogen. It is a recombinant humanized monoclonal antibody that targets the interleukin-6 receptor (IL-6R), binding both soluble and membrane-bound forms (sIL-6R and mIL-6R) to inhibit IL-6-mediated signaling. BAT1806 has demonstrated equivalent efficacy, safety, immunogenicity, and pharmacokinetic profiles compared to reference tocilizumab in patients with moderate-to-severe rheumatoid arthritis who had an inadequate response to methotrexate. It is approved in China for rheumatoid arthritis (RA), systemic juvenile idiopathic arthritis (sJIA), and cytokine release syndrome (CRS). The drug has been submitted for approval in other regions including the US and EU[1][4][5][7].
