FDA issues draft guidance on biosimilar product development

Press Announcements; FDA issues draft guidance on biosimilar product development:

"The U.S. Food and Drug Administration today issued three draft guidance documents on biosimilar product development to assist industry in developing such products in the United States.
“When it comes to getting new biosimilar products on the market, FDA has taken an innovative approach to supporting their development at every step of the process,” said Janet Woodcock, M.D., director of FDA’s Center for Drug Evaluation and Research. “These draft documents are designed to help industry develop biosimilar versions of currently approved biological products, which can enhance competition and may lead to better patient access and lower cost to consumers.”"

According to the press release, these are the 3 new draft guidance documents:

Scientific Considerations in Demonstrating Biosimilarity to a Reference Product: The draft guidance is intended to assist companies in demonstrating that a proposed therapeutic protein product is biosimilar to a reference product for the purpose of submitting an application, called a “351(k)” application, to the FDA. This draft guidance describes a risk-based “totality-of-the-evidence” approach that the FDA intends to use to evaluate the data and information submitted in support of a determination of biosimilarity of the proposed product to the reference product. As outlined in the draft guidance, FDA recommends a stepwise approach in the development of biosimilar products.

Quality Considerations in Demonstrating Biosimilarity to a Reference Protein Product: The draft guidance provides an overview of analytical factors to consider when assessing biosimilarity between a proposed therapeutic protein product and a reference product for the purpose of submitting a 351(k) application. This includes the importance of extensive analytical, physico-chemical and biological characterization in demonstrating that the proposed biosimilar product is highly similar to the reference product notwithstanding minor differences in clinically inactive components.

Biosimilars: Questions and Answers Regarding Implementation of the Biologics Price Competition and Innovation Act of 2009: The draft guidance provides answers to common questions from people interested in developing biosimilar products. The question and answer format addresses questions that may arise in the early stages of product development, such as how to request meetings with the FDA, addressing differences in formulation from the reference product, how to request exclusivity, and other topics.
