Eydenzelt (40 mg/mL solution for injection in vial and pre-filled syringe), a biosimilar to Eylea^® (aflibercept), is recommended for approval to treat multiple retinal disorders, including neovascular (wet) age-related macular degeneration (AMD), macular edema following retinal vein occlusion (RVO, branch RVO or central RVO), diabetic macular edema (DME) and myopic choroidal neovascularisation (myopic CNV). In a Phase III study of Eydenzelt, the efficacy, safety, pharmacokinetics and immunogenicity of Eydenzelt was compared to Eylea in patients with diabetic macular edema (DME), demonstrating therapeutic equivalence to Eylea by meeting the predefined equivalence criteria.¹ If marketing authorisation is granted by the European Commission (EC), Eydenzelt would be one of the first-wave aflibercept biosimilars in Europe.

Stoboclo (60 mg solution for injection in pre-filled syringe) and Osenvelt (120 mg solution for injection in vial) have been recommended for approval for all indications of the reference products Prolia^® and Xgeva^®, respectively. The positive CHMP opinion was based on the totality of evidence including results from a Phase III clinical trial in postmenopausal osteoporosis (PMO), and the results showed that CT-P41 had equivalent efficacy and pharmacodynamics (PD) to reference denosumab, with similar pharmacokinetics (PK) and comparable safety and immunogenicity profiles.²

Avtozma, a biosimilar referencing RoActemra^® (tocilizumab), has been recommended for all indications of its reference product, including moderate to severely active rheumatoid arthritis (RA), active systemic juvenile idiopathic arthritis (sJIA), juvenile idiopathic polyarthritis (pJIA) and giant cell arteritis (GCA). The positive CHMP opinion for Avtozma was supported by a comprehensive data package and totality of evidence demonstrating Avtozma’s biosimilarity to RoActemra, with no clinically meaningful differences in efficacy, PK equivalence, safety or immunogenicity.^3,4

“With CHMP approvals for Eydenzelt, Avtozma, and Prolia/Xgeva biosimilars, Celltrion solidifies its leadership in the European biosimilar market, offering one of the most extensive antibody biosimilar portfolios. Our vertically integrated model ensures supply chain stability while addressing the specific challenges faced by European healthcare professionals and patients. These approvals underscore our commitment to supporting European healthcare systems by improving access to high-quality, affordable treatments,” said Taehun Ha, Vice President and Head of Europe. “Our focus remains on empowering clinicians with the tools and solutions they need, as we aim to transition from a pioneer to a frontier leader in European healthcare.”

The CHMP’s recommendations will now be referred to the EC, which will decide whether to grant a marketing authorisation for Eydenzelt, Stoboclo and Osenvelt, and Avtozma. If marketing authorisations are granted, the three biosimilars will be made available across EU member states, furthering Celltrion’s commitment to delivering innovative and accessible healthcare solutions.
