FDA Approves Celltrion’s Biosimilar to ACTEMRA

AVTOZMA is indicated for the treatment of multiple diseases, including rheumatoid arthritis, giant cell arteritis, polyarticular juvenile idiopathic arthritis and more.

The U.S. Food and Drug Administration (FDA) has approved Celltrion’s AVTOZMA (CT-P47, tocilizumab-anoh) in both an intravenous (IV) and subcutaneous (SC) formulation as a biosimilar to ACTEMRA.

AVTOZMA is indicated for the treatment of multiple diseases including rheumatoid arthritis (RA), giant cell arteritis (GCA), polyarticular juvenile idiopathic arthritis (pJIA), systemic juvenile idiopathic arthritis (sJIA) and coronavirus disease (COVID-19).

“Introducing both IV and SC formulations of AVTOZMA provides flexibility and a wider range of treatment options,” said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. “This approval represents a strategic addition to our immunology portfolio, further strengthening our commitment to delivering accessible and high-quality treatment options for patients and healthcare providers. Our goal is to provide safe and effective alternatives and ensure appropriate access so plan sponsors can address unique population needs.”

The FDA’s decision is based on a comprehensive data package and the totality of evidence, including the results from a phase III study demonstrating biosimilarity between AVTOZMA and reference tocilizumab in patients with moderate to severe active RA.

AVTOZMA will be available in both IV and SC formulations, with the same formulation and dosages as the reference product. The IV infusion is provided as 80 mg/4 mL (20 mg/mL), 200 mg/10 mL (20 mg/mL), 400 mg/20 mL (20 mg/mL) and the SC injection comes in 162 mg/0.9 mL in a single-dose prefilled syringe or single-dose autoinjector.

AVTOZMA is Celltrion’s seventh biosimilar granted marketing authorization in the U.S.
