Pfizer announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) has adopted a positive opinion, recommending marketing authorization for Zirabev (bevacizumab), a potential biosimilar to Avastin (bevacizumab). Zirabev is a monoclonal antibody for the treatment of metastatic carcinoma of the colon or rectum, metastatic breast cancer, unresectable advanced, metastatic or recurrent non-small cell lung cancer (NSCLC), advanced and/or metastatic renal cell cancer and persistent, recurrent or metastatic carcinoma of the cervix.

The regulatory submission is supported with a comprehensive data package and evidence demonstrating biosimilarity to the originator product. This includes results from the phase III REFLECTIONS B739-03 clinical comparative study, which demonstrated clinical equivalence and found no clinically meaningful differences between Zirabev and Avastin in patients with advanced non-squamous NSCLC. As part of the overall REFLECTIONS clinical trial program, Zirabev has been studied in approximately 400 subjects.
