On 24 February 2025, Celltrion announced that the European Commission has approved Avtozma® (CT-P47), biosimilar to Roche’s RoActemra® (tocilizumab). Avtozma® is approved for all indications of RoActemra®, including moderate to severely active rheumatoid arthritis (RA), active systemic juvenile idiopathic arthritis (sJIA), polyarticular juvenile idiopathic arthritis (pJIA) and giant cell arteritis (GCA).
Celltrion’s Avtozma® is the third tocilizumab biosimilar approved in the EU, following Fresenius Kabi’s Tyenne®, in both IV and SC forms, in November 2023, and Biogen’s IV Tofidence™, in June 2024.
Earlier this month, Celltrion’s SC tocilizumab formulation was approved in Korea, following Korean approval of IV tocilizumab in 200mg/10ml and 400mg/20ml formulations in December 2024.
In January 2025, Avtozma® became the third tocilizumab biosimilar approved in the US, trailing Fresenius Kabi’s Tyenne® (tocilizumab-aazg) (SC formulation, March 2024) and Biogen/Bio-Thera’s Tofidence®/BAT1806 (tocilizumab-bavi) (IV formulation, September 2023).
