• The BLA for CT-P39 was based on totality of evidence including results from Phase III data demonstrating comparable efficacy and safety profile with the reference product XOLAIR® (omalizumab) in patients with chronic spontaneous urticaria

JERSEY CITY, NJ, USA I March 10, 2024 I Celltrion USA today announced that the company has submitted a Biologics License Application (BLA) for CT-P39, an interchangeable biosimilar candidate to XOLAIR® (omalizumab) to the U.S. Food and Drug Administration (FDA).[1]

“We are pleased with the rapid progress made in the development of CT-P39, and we look forward to expanding our portfolio beyond immunology and oncology,” said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. “We will continue to build upon our strong track record of developing and manufacturing high-quality biosimilars to help improve the lives of patients.”

The BLA submission includes results from a global Phase III clinical trial designed to evaluate the efficacy, safety, and pharmacokinetics of CT-P39 compared to the reference product XOLAIR® in patients with chronic spontaneous urticaria (CSU) up to Week 40.
