Biologics License Application (BLA)

Biologics License Application (BLA) - Overview

Health Authorities (HAs) have begun implementing risk-based review procedures for the approval of Biologics License Applications (BLAs) due to evolving Regulatory enforcement for advanced therapies like cellular and gene therapy products, as well as other complex biologics/biosimilars that necessitate a thorough evaluation of drug product quality, safety, and efficacy aspects. As a result, there might be chances of missing out on mandatory information in the Biologics License Applications that could lead to a Refuse-to-File (RTF) action by the United States Food and Drug Administration (US FDA). Therefore, BLA sponsors prefer to be associated with a proven Regulatory partner with significant experience in Regulatory consulting for biologics and biosimilars.

Freyr assists sponsors with end-to-end Regulatory support in the BLA submission process, from pre-BLA meetings/BPD meetings to post-approval Lifecycle Management (LCM) activities. Additionally, our experienced team provides Regulatory support for marketing authorizations and relevant LCM for various biological products approved in both the Regulatory paths (i.e., 351(a) Innovator Biologics Regulatory pathway and 351(k) Biosimilar Regulatory pathway).
