Infliximab-dyyb (Celltrion)

JERSEY CITY, NJ, USA I March 9, 2025 I Celltrion today announced the U.S. Food and Drug Administration (FDA) approved OMLYCLO ® (omalizumab-igec) as the first and only biosimilar designated as interchangeable with XOLAIR ® (omalizumab) for the treatment of moderate to severe persistent asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), Immunoglobulin E (IgE)-mediated food allergy, and chronic spontaneous urticaria (CSU). [2] “We are proud to achieve the approval of the first biosimilar to omalizumab in the U.S., which will help broaden access to this important medicine for patients with allergic and respiratory conditions, as well as for physicians, payers and providers,” said Hetal Patel, Vice President of Medical Affairs at Celltrion USA. “The interchangeability designation of OMLYCLO reinforces confidence among physicians and patients that there is no decrease in effectiveness or increase in safety risk associated with switching between OMLYCLO and the reference product.” The FDA approval and designation of interchangeability are based on comprehensive clinical evidence, including results from a global Phase III clinical trial involving 619 adult patients with CSU up to Week 40. Patients were randomized to receive 300 mg or 150 mg of OMLYCLO or reference product every 4 weeks. From Week 12, patients who received OMLYCLO were continued on OMLYCLO, and patients who received 300mg of the reference product were re-randomized in a 1:1 ratio to switch to OMLYCLO or to continue reference product. From Week 24, patients were followed up until Week 40 without dosing. The result demonstrated the comparable efficacy and safety of OMLYCLO to reference product during both treatment and off-dose periods. [1] An interchangeable biosimilar is a biosimilar that meets additional requirements outlined by the law that allows for the FDA to approve biosimilar and interchangeable biosimilar medications. [3] “The approval of OMLYCLO could have a meaningful impact for the medical community and patients, offering a high quality and affordable treatment option, while reducing the burden of healthcare costs,” said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. “With our integrated development, manufacturing, and commercialization platform, Celltrion remains committed to alleviating treatment costs and delivering life-changing medicines to support patients with allergic conditions in the U.S.” About OMLYCLO ® (omalizumab-igec) OMLYCLO ® (omalizumab-igec) is the first U.S. Food and Drug Administration (FDA)-approved anti-IgE antibody biosimilar referencing XOLAIR ® (omalizumab). OMLYCLO 75 mg/0.5 mL and 150 mg/mL solution in a single-dose prefilled syringe is approved as interchangeable with reference product for all indications based on comprehensive data and clinical evidence confirming the therapeutic equivalence to XOLAIR. [1],[2] OMLYCLO was also approved by the European Commission (EC) in May 2024. INDICATION OMLYCLO® (omalizumab-igec) injection, is an anti-IgE antibody indicated for: Limitations of Use: Not indicated for: acute bronchospasm or status asthmaticus; emergency treatment of allergic reactions, including anaphylaxis; other forms of urticaria. IMPORTANT SAFETY INFORMATION WARNING: ANAPHYLAXIS Anaphylaxis presenting as bronchospasm, hypotension, syncope, urticaria, and/or angioedema of the throat or tongue, has been reported to occur after administration of omalizumab products. Anaphylaxis has occurred as early as after the first dose of omalizumab products, but also has occurred beyond 1 year after beginning regularly administered treatment. Because of the risk of anaphylaxis, initiate OMLYCLO therapy in a healthcare setting and closely observe patients for an appropriate period of time after OMLYCLO administration. Health care providers administering OMLYCLO should be prepared to manage anaphylaxis which can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should symptoms occur. Selection of patients for self-administration of OMLYCLO should be based on criteria to mitigate risk from anaphylaxis. Contraindications: Severe hypersensitivity reaction to OMLYCLO or any ingredient of OMLYCLO. Anaphylaxis. Omalizumab products, including OMLYCLO, have been associated with anaphylaxis, reported in both clinical trials and postmarketing data. Patients with a history of anaphylaxis to foods, medications, or other causes face an increased risk. Initiate OMLYCLO only in a healthcare setting with anaphylaxis management capabilities. Patients should be monitored for an appropriate period post-administration, informed of symptoms, and instructed to seek immediate medical care if they occur. Malignancy. Malignancies have been observed in clinical studies, with various cancer types reported. The long-term risk, especially in high-risk groups, is unknown. Acute Asthma Symptoms and Deteriorating Disease. Omalizumab products have not been shown to alleviate asthma exacerbations acutely. Do not use OMLYCLO to treat acute bronchospasm or status asthmaticus. Corticosteroid Reduction. Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of OMLYCLO therapy for asthma or CRSwNP. Eosinophilic Conditions. Be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy, especially upon reduction of oral corticosteroids. Fever, Arthralgia, and Rash. Stop OMLYCLO if a patient develops this constellation of signs and symptoms, including arthritis/arthralgia, rash, fever, and lymphadenopathy. Parasitic (Helminth) Infection. Monitor patients at high risk of geohelminth infection while on OMLYCLO therapy. Laboratory Tests. Omalizumab increases serum total IgE due to drug:IgE complexes. Do not use serum total IgE levels within one year of discontinuation to reassess dosing regimen, as they may not reflect steady-state free IgE. Potential Medication Error Related to Emergency Treatment of Anaphylaxis. OMLYCLO should not be used for the emergency treatment of allergic reactions, including anaphylaxis. Instruct patients that OMLYCLO is for maintenance use to reduce allergic reactions, including anaphylaxis, while avoiding food allergens.
