Biologics License Applications (BLA)

Biologics License Applications (BLA)

Biologic medicinal products are becoming increasingly important for treating chronic and life-threatening diseases, and many biopharmaceutical companies are developing such products to meet unmet medical needs. However, the approval of Biologics License Applications (BLAs) by the US FDA requires careful consideration of development strategies.

The Challenging Part of BLA Filing

Submitting a BLA is challenging, especially for advanced therapies like cellular and gene therapy products and other complex biologics/biosimilars, which require extensive evaluation of quality, safety, and efficacy aspects. This has led to the implementation of risk-based review procedures by health authorities. Which in turn has increased the complexity of submission mandates with an extensive list of documents. Missing mandatory information in BLAs could lead to an RTF action by the US FDA. Thus, BLA sponsors prefer substantial regulatory partners with significant experience in regulatory consulting for biologics and biosimilar products.
