Biologic License Application (BLA)

Biologic License Application (BLA) Credit: Barbara Bellingham, Wellcome Images
Definition:

Biological products are approved for marketing in the United States under the provisions of the Public Health Service (PHS) Act. The Act requires biologic manufacturers to obtain a license to sell the product in interstate commerce.

Types of products requiring a biologic license include vaccines, blood and blood by-products, some types of monoclonal antibodies, and tissue and cellular products.

The FDA's Center for Biologics Evaluation and Research (CBER) and the Center for Drug Evaluation and Research (CDER) share responsibility for the regulation of biologics. CBER regulates allergenics, blood and blood components, devices developed to prevent contamination of blood, blood components and cellular product, software used to collect blood and blood, gene therapy, human tissues, cellular products, vaccines, and xentranspalantation products (live animal organs, cells or tissues used to treat human diseases.

The CDER has responsibility for regulating monoclonal antibodies for use in vivo, proteins extracted from plants, animals or microorganisms, and other non-vaccine therapeutic immunomotherapies.

While it has some similarities to a New Drug Application (NDA), a BLA has its own unique set of requirements.

A biologics license application contains details on the chemistry, pharmacology, source materials, manufacturing processes, labeling and medical affects of the biologic product as well as data from clinical studies. If the information provided meets FDA requirements, the application is approved and a license is issued allowing the firm to market the product.

Since they contain information from pre-clinical toxicology studies to phase 3 clinical trial data, a BLA application may run to thousands of pages long.

Downloadable forms, instructions, and a description of the process for submitting a BLA information on electronic submissions are available on the CBER section of the FDA website.

The FDA approved 10 BLAs in 2011 including Albumin (human), Hemacord (Hematopoietic Progenitor Cells -HPC-C), Ultraqual HBV PCR assay (Hepatitis B Virus), Anascorp Centruroides (scorpion immune F(ab')2 equine injection), two types of source plasma, Spherusol Coccidioides immitis (spherule-derived skin test antigen), LaViv Azficel-T (for removal of fold wrinkles), and Adenovirus Vaccine Live Oral Type 4 and Type 7 (immunization against febrile acute respiratory disease).
