SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a guidance for industry entitled “Considerations in Demonstrating Interchangeability With a Reference Product.” This guidance is intended to assist sponsors in demonstrating that a proposed therapeutic protein product (proposed interchangeable product) is interchangeable with a reference product for the purposes of submitting a marketing application or supplement under section 351(k) of the PHS Act (42 U.S.C. 262(k)).

Section 351(k) of the PHS Act sets forth the requirements for an application for a proposed biosimilar product and for an application or a supplement for a proposed interchangeable product. Specifically, section 351(k)(4) provides that upon review of an application submitted under section 351(k), or any supplement to such application, FDA will determine the biological product to be interchangeable with the reference product if FDA determines that the information submitted in the application (or supplement) is sufficient to show that the biological product is biosimilar to the reference product and can be expected to produce the same clinical result as the reference product in any given patient; and for a biological product that is administered more than once to an individual, the risk in terms of safety or diminished efficacy of alternating or switching between use of the biological product and the reference product is not greater than the risk of using the reference product without such alternation or switch. Section 351(i) of the PHS Act states that the term interchangeable or interchangeability, in reference to a Start Printed Page 21344biological product that is shown to meet the standards described in section 351(k)(4), means that the biological product may be substituted for the reference product without the intervention of the healthcare provider who prescribed the reference product.

This guidance gives an overview of important scientific considerations in demonstrating interchangeability with a reference product, including:

  • The data and information recommended to support a demonstration of interchangeability
  • Considerations for the design and analysis of a switching study or studies to support a demonstration of interchangeability
  • Considerations regarding the comparator product in a switching study or studies
  • Abbreviated considerations for developing presentations, container closure systems, and delivery device constituent parts for proposed interchangeable products

This guidance finalizes the draft guidance issued on January 18, 2017. Changes made to the guidance took into consideration the comments received. FDA provided changes to clarify its recommendations for demonstrating interchangeability with the reference product. FDA intends to provide more detailed recommendations on the data and information recommended to support the proposed interchangeable product's presentation and related issues in a separate guidance.

In the Federal Register of January 18, 2017 (82 FR 5579), FDA announced the availability of the draft guidance for industry “Considerations in Demonstrating Interchangeability With a Reference Product.” FDA requested comment on the following questions: (1) Are there considerations in addition to comparability assessments that FDA should consider in regulating post-approval manufacturing changes of interchangeable products and (2) how, if at all, should the Agency consider conditions of use that are licensed for the reference product after an interchangeable product has been licensed. The comments submitted in response to these questions are being considered; FDA will address these topics in future guidance, as appropriate.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Considerations in Demonstrating Interchangeability With a Reference Product.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This guidance is not subject to Executive Order 12866.

II. Paperwork Reduction Act of 1995
