Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is announcing the availability of a guidance for industry entitled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product.” This guidance is intended to assist sponsors in demonstrating that a proposed therapeutic protein product is biosimilar to a reference product for the purpose of submitting a marketing application through an abbreviated licensure pathway. This guidance gives an overview of FDA's approach to determining biosimilarity.

FDA is announcing the availability of a guidance for industry entitled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product.” This guidance is intended to assist sponsors in demonstrating that a proposed therapeutic protein product is “biosimilar”  to a reference product for the purpose of submitting a marketing application through the abbreviated licensure pathway under section 351(k) of the Public Health Service Act (PHS Act) (42 U.S.C. 262(k)).
The Biologics Price Competition and Innovation Act of 2009 (BPCI Act), enacted as part of the Affordable Care Act (Pub. L. 111-148) on March 23, 2010, created an abbreviated licensure pathway under section 351(k) of the PHS Act for biological products demonstrated to be biosimilar to, or interchangeable with, a reference product. Under this abbreviated licensure pathway, FDA will license a proposed biological product submitted under section 351(k) of the PHS Act if FDA “determines that the information submitted in the application . . . is sufficient to show that the biological product is biosimilar to the reference product. . . .” and the 351(k) applicant (or other appropriate person) consents to an inspection of the facility that is the subject of the application (i.e., a facility in which the proposed biological product is manufactured, processed, packed, or held). The guidance gives an overview of FDA's approach to determining biosimilarity. FDA intends to consider the totality of the evidence submitted in a 351(k) application and is recommending that sponsors use a stepwise approach in their development of biosimilar products. The guidance discusses important scientific considerations in demonstrating biosimilarity, including:
- A stepwise approach to demonstrating biosimilarity, which can include a comparison of the proposed product and the reference product with Start Printed Page 24259respect to structure, function, animal toxicity, human pharmacokinetics (PK) and pharmacodynamics (PD), clinical immunogenicity, and clinical safety and effectiveness;
- The totality-of-the-evidence approach that FDA will use to review applications for biosimilar products, consistent with a longstanding Agency approach to evaluation of scientific evidence; and
- General scientific principles in conducting comparative structural analyses, functional assays, animal testing, human PK and PD studies, clinical immunogenicity assessment, and comparative clinical trials (including clinical study design issues).
In the Federal Register of February 15, 2012 (77 FR 8883), FDA announced the availability of the draft guidance of the same title dated February 2012. FDA received a number of comments on the draft guidance. In response to these comments, FDA provides further clarification of the scientific considerations applicable to the conduct of comparative structural analysis, functional assays, animal studies, and clinical testing. The final guidance also provides additional information on clinical trial design and selection of study endpoint and population. It also explains FDA's current thinking on when a comparative clinical trial may not be needed. In addition, editorial changes were made to improve clarity. The guidance announced in this notice finalizes and replaces the draft guidance dated February 2012.
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the Agency's current thinking on scientific considerations in demonstrating biosimilarity to a reference product. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.
Interested persons may submit either electronic comments regarding this document to http://www.regulations.gov or written comments to the Division of Dockets Management (see ADDRESSES). It is only necessary to send one set of comments. Identify comments with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday, and will be posted to the docket at http://www.regulations.gov.
III. The Paperwork Reduction Act of 1995
This guidance describes information collection provisions that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (the PRA) (44 U.S.C. 3501-3520). This guidance references information collections that are already approved by OMB and are not expected to change as a result of the guidance. This includes information collections related to the submission of: (1) An investigational new drug application, which is covered under 21 CFR part 312 and approved under OMB Control No. 0910-0014; (2) a new drug application, which is covered under 21 CFR 314.50 and approved under OMB control number 0910-0001; (3) a biologics license application under section 351(a) of the PHS Act, which is covered under 21 CFR part 601 and approved under OMB control number 0910-0338; and (4) a biologics license application under section 351(k) of the PHS Act, which is covered under 21 CFR part 601 and approved under OMB control number 0910-0719.

L. 111-148, “biosimilar” or “biosimilarity” means “that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive components,” and that “there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity, and potency of the product.”Back to Citation
