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

[[Page 21344]]

biological 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

    This guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
are subject to review by the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The 
collections of information under 21 CFR part 312 have been approved 
under OMB control number 0910-0014; the collections of information 
under 21 CFR part 601 have been approved under OMB control number 0910-
0338; and the collections of information under section 351(k) of the 
PHS Act have been approved under OMB control number 0910-0719.
