Safety Profile of Biosimilar Filgrastim (Zarzio/Zarxio): A Combined Analysis of Phase III Studies

摘要

Background. Evaluation of adverse events (AEs) in pivotal registration trials and ongoing postmarketing surveillance is important for all biologics, including biosimilars. A combined analysis of two pivotal registration studies was performed to strengthen evidence on safety for biosimilar filgrastim EP2006 in patients with breast cancer receiving myelosuppressive chemotherapy, a sensitive clinical setting to confirm biosimilarity of filgrastim.
