18.11.2025 03:51:00 CET | Business Wire | Press Release
The European Commission (EC) has granted a line extension in the European Union (EU) for Celltrion’s Omlyclo™ (omalizumab), Europe’s first and only omalizumab biosimilar, for the 300 mg/2ml prefilled syringe (PFS).The European Commission (EC) approved Omlyclo™ 75 mg/0.5ml and 150mg/1ml solution for injection in pre-filled syringe in May 2024.
Omlyclo™ is indicated for the treatment of patients with allergic asthma, chronic spontaneous urticaria (CSU) and chronic rhinosinusitis with nasal polyps (CRSwNP).
“The additional strength of Omlyclo™ 300mg can significantly decrease the frequency of injections, and reduce injection burden and discomfort, without compromising efficacy and safety,” said Nam Lee, Vice President of Global Medical Affairs at Celltrion. “These improvements may contribute to an enhanced treatment journey for patients by helping reduce the disease burden they face throughout their care. Given its distinctive product profile, Omlyclo™ 300mg has the potential to become an important additional option for the management of allergic diseases.”
Xolair® (omalizumab) is designed to target and block immunoglobulin E (IgE). By reducing free IgE, down-regulating high-affinity IgE receptors and limiting mast cell degranulation, omalizumab minimizes the release of mediators throughout the allergic inflammatory cascade. Omalizumab has a patient exposure surpassing 1.99 million patient-years.1 Its therapeutic effect has been established for more than 20 years through numerous clinical trials and real-world studies.

Americhem Launches nDryve™: PFAS-Free In-Melt Technology Platform for Functional Fibers1.4.2026 13:00:00 CEST | Press Release
Americhem, Inc., a global polymer solutions provider, today announced the launch of nDryve™, a PFAS-free, in-melt surface-modifying technology platform designed to deliver durable multi-fluid repellency against alcohol and other low-surface-energy fluids in fiber systems. As global regulations accelerate the phase-out of per- and polyfluoroalkyl substances (PFAS), manufacturers are under increasing pressure to maintain barrier performance without fluorinated chemistries. nDryve™ was developed to address this shift, offering a PFAS-free, in-melt alternative to conventional surface applied treatments. Engineered for Performance Without PFAS Often referred to as “forever chemicals,” PFAS have come under heightened regulatory scrutiny due to their persistence and potential environmental and health impacts. nDryve™ integrates directly into the polymer during melt processing, embedding surface-modifying functionality within the fiber matrix rather than relying on removable finishes.
