Celltrion announced that the European Commission (EC) has approved Omlyclo® (CT-P39), an omalizumab biosimilar referencing Xolair®. Omlyclo® is approved for the treatment of allergic asthma, chronic spontaneous urticaria (CSU), and chronic rhinosinusitis with nasal polyps (CRSwNP). The EC approval of Omlyclo® follows the recommendation for marketing authorisation issued by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) in March 2024.

The decision is based on clinical evidence, including results from a global Phase III clinical trial designed to evaluate the efficacy, safety and pharmacokinetics of Omlyclo® compared to the reference product Xolair® in patients with CSU up to Week 40. Omlyclo® is Celltrion?s sixth biosimilar, besides Remsima® SC, a subcutaneous formulation of infliximab, approved for use in the EU, following the approval of Remsima® (biosimilar infliximab), Truxima® (biosimilar rituximab), Herzuma® (biosimilar trastuzumab), Yuflyma® (biosimilar adalimumab), and Vegzelma® (biosimilar bevacizumab). Omlyclo® is currently under review by the U.S. Food and Drug Administration (FDA), following the submission in March 2024.

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 (aCSU) and chronic rhinosinusitis with nasal polyps (CRSwNP).
