Celltrion’s Omlyclo™, the first and only omalizumab biosimilar in Europe, will be commercially available starting in Norway, with subsequent rollouts in European countriesResults from the global Phase III clinical trial of Omlyclo™ (CT-P39) for the treatment of chronic spontaneous urticaria (CSU), allergic asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) will be presented at a satellite symposium during the 2025 European Academy of Dermatology and Venereology (EADV) CongressCelltrion highlights the strength of its expanding dermatology portfolio with positive clinical results for CT-P55, a biosimilar candidate referencing secukinumabWith the launch of Omlyclo™, Celltrion underscores its commitment to advancing innovative and accessible treatments in immunology and dermatology INCHEON, South Korea--(BUSINESS WIRE)--Celltrion, Inc. today showcased its longstanding commitment to expanding its biosimilar portfolio in the field of immuno-dermatology by attending the 2025 European Academy of Dermatology and Venereology (EADV) Congress, held 17-20 September in Paris, France. Following the European Commission (EC) approval of Omlyclo™, the first and only omalizumab biosimilar in Europe in May 2024, Omlyclo™ will be commercially available starting in Norway, with subsequent rollouts in European countries. As part of Celltrion’s mission to advance knowledge and understanding in dermatology, especially in chronic spontaneous urticaria (CSU), the company hosted satellite symposium presenting the results of the global Phase III clinical trial of Omlyclo™. The global Phase III clinical trial involved 619 patients with CSU, following them up to week 40. Patients were randomized to receive 300 mg or 150 mg of Omlyclo™, or reference product, every 4 weeks. Starting from week 12, patients who received Omlyclo™ were continued on the same treatment and patients who initially received 300mg of the reference product were re-randomized in a 1:1 ratio to either switch to Omlyclo™ or to continue receiving the reference product. From week 24 until week 40, patients were observed without dosing. The results demonstrated that Omlyclo™ had comparable efficacy and safety to reference product during both treatment and off-dose periods.1,2 “Immuno-dermatology diseases such as CSU significantly impact a patient's quality of life (QoL), affecting various aspects including mental and emotional well-being, social life, daily activities, and even financial stability,” said Prof. Martin Metz, MD, Deputy Director of the Institute of Allergology, Charité- Universitätsmedizin Berlin, Germany. “Availability of an omalizumab biosimilar in the EU is both timely and significant, offering a much-needed option for patients and healthcare providers. The clinical trial of Omlyclo™ clearly met the safety and efficacy endpoints, thereby offering a tangible promise for all eligible patients.” “At this year’s EADV Congress, Celltrion reinforced dermatologists’ confidence in Omlyclo™, the first and only omalizumab biosimilar in Europe, by presenting robust clinical evidence supporting its biosimilarity and assuring physicians that switching from the original product to Omlyclo™ is safe,” said Taehun Ha, Senior Vice President and Head of Europe at Celltrion. “As a biosimilar-focused company, we remain committed to building long-term trust with healthcare professionals and strengthening our presence in the European market.” To further its commitment to immunology, Celltrion presented an abstract for its proposed secukinumab biosimilar candidate, CT-P55 which demonstrated comparable efficacy and safety profiles to the reference secukinumab in healthy subjects.3 With the launch of Omlyclo™, Celltrion's dermatology portfolio now comprises five products: Remsima™ (infliximab), Remsima™ SC (subcutaneous infliximab), Yuflyma™ (adalimumab), SteQeyma™ (ustekinumab), and Omlyclo™ (omalizumab), further strengthening the company’s presence in the treatment of immune-mediated skin conditions. Celltrion plans to continue solidifying its position in dermatology by advancing biosimilar candidates, including CT-P55, and expanding its post-commercialization activities within the therapeutic area. Notes to Editors: About Omlyclo™ (omalizumab)Omlyclo™ is the first European Commission (EC) approved anti-IgE antibody biosimilar referencing Xolair® (omalizumab). In the EU, Omlyclo™ is indicated for the treatment of patients with allergic asthma, chronic spontaneous urticaria (CSU) and chronic rhinosinusitis with nasal polyps (CRSwNP). About CT-P55 (biosimilar candidate of secukinumab)CT-P55 is a proposed biosimilar of reference secukinumab developed by Celltrion, Inc. Secukinumab is a human monoclonal antibody that selectively targets interleukin-17A and has been demonstrated to be highly efficacious in the treatment of moderate to severe plaque psoriasis, starting at early time points, with a sustained effect and a favorable safety profile.4 CT-P55 is currently undergoing global Phase III clinical trials. About CelltrionCelltrion is a leading biopharmaceutical company that specializes in researching, developing, manufacturing, marketing and sales of innovative therapeutics that improve people's lives worldwide.

Approval of AVTOZMA® (tocilizumab-anoh) intravenous infusion expands label to include treatment of adults and pediatric patients aged 2 years and older with cytokine release syndrome (CRS) [1]AVTOMZA received FDA approval in January 2025, for multiple inflammatory indications including rheumatoid arthritis (RA), giant cell arteritis (GCA), polyarticular juvenile idiopathic arthritis (pJIA), systemic juvenile idiopathic arthritis (sJIA) and coronavirus disease (COVID-19) in IV formulation [1] INCHEON, South Korea, Aug. 6, 2025-- Celltrion, Inc. today announced that the U.S. Food and Drug Administration (FDA) has approved an expanded indication of the intravenous (IV) formulation of AVTOZMA® (tocilizumab-anoh) to include the treatment of cytokine release syndrome (CRS) in adults and pediatric patients aged 2 years and older. Following FDA approval of the additional indication for CRS, AVTOZMA IV now aligns with all indications approved for ACTEMRA® IV in the United States.[1] Earlier this year, the FDA approved AVTOZMA as a biosimilar to ACTEMRA in IV formulations 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).[1] CRS is a potentially life-threatening condition that occurs when the immune system is highly activated, leading to the rapid and excessive release of cytokines into the bloodstream. During a cytokine storm, the overactivated immune system can cause widespread inflammation and damage to healthy tissue and organs throughout the body with symptoms ranging from mild, flu-like symptoms to more severe complications such as low blood pressure, difficulty breathing, and multi-organ failure.[2]"We are proud that AVTOZMA IV has now achieved full indication alignment with the reference ACTEMRA IV. This milestone marks an important step forward in our mission to deliver a safe and effective therapy for CRS," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. "This FDA approval expands access to high-quality biologics and supports beneficial patient outcomes across multiple therapeutic areas." In accordance with the patent settlement agreement with Genentech, the IV formulation of AVTOZMA is expected to be available in the U.S. on August 31, 2025. Celltrion holds a license to market the subcutaneous formulation in the U.S. commencing on the licensed launch date, which remains confidential. Notes to Editors: About AVTOZMA® (CT-P47, tocilizumab-anoh) AVTOZMA® (tocilizumab-anoh), containing the active ingredient tocilizumab, is a recombinant humanized monoclonal antibody that acts as an interleukin 6 (IL-6) receptor antagonist.
