Frequently Asked Questions

A BLA is the formal submission to the U.S. FDA to request approval for a biologic product. It includes evidence from preclinical, clinical, and manufacturing studies.

BLAs are for biologics, while NDAs are for small-molecule drugs. BLAs place greater emphasis on CMC data due to the complexity of biologic manufacturing.

A BLA includes administrative and summary information as well as full CMC, nonclinical, and clinical data modules, proposed labeling, and risk management plans.

Expert writers ensure data is clear, accurate, and compliant—minimizing FDA questions and avoiding costly delays.

Engaging early in development ensures consistency across all modules, reduces rework, and keeps your submission on track.
