Considerations in Demonstrating Interchangeability With a 
Reference Product; Draft Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a draft guidance for industry entitled 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 or proposed product) is interchangeable with a 
reference product for the purposes of submitting a marketing 
application or supplement under the Public Health Service Act (PHS 
Act). This guidance is one in a series of guidances that FDA has 
developed to implement the Biologics Price Competition and Innovation 
Act of 2009 (BPCI Act).

10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by March 20, 2017.

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 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 or proposed 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)). The BPCI Act amends the PHS Act and other statutes to 
create an

[[Page 5580]]

abbreviated licensure pathway in section 351(k) for biological products 
shown to be biosimilar to or interchangeable with an FDA-licensed 
biological reference product (see sections 7001 through 7003 of the 
Patient Protection and Affordable Care Act Of 2010 (Affordable Care 
Act) (Pub. L. 111-148)).
    Section 351(k) of the PHS Act sets forth the requirements for an 
application for a proposed biosimilar product and 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 an 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 biological product that is shown 
to meet the standards described in subsection 351(k)(4), means that the 
biological product may be substituted for the reference product without 
the intervention of the health care provider who prescribed the 
reference product.
    This guidance gives an overview of important scientific 
considerations in demonstrating interchangeability, including:
     The data and information needed to support a demonstration 
of interchangeability;
     Considerations for the design and analysis of a switching 
study or studies to support a demonstration of interchangeability;
     Recommendations regarding the use of U.S.-licensed 
reference products in a switching study or studies; and
     Considerations for developing presentations, container 
closure systems, and delivery device constituent parts for proposed 
interchangeable products.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the current thinking of FDA on topics 
sponsors should consider when seeking to demonstrate that a proposed 
therapeutic protein product is interchangeable with a reference 
product. It does not establish any rights for any person and is not 
binding on FDA or the public.

II. Topics for Comment

    In addition to comment on the draft guidance, we also invite 
general comments on interchangeability, including comments on 
regulation of an interchangeable product over its lifecycle, as well as 
comments on the following topics:
    1. Since the mid-1990s, FDA has approved manufacturing changes for 
biological products based on data from comparability assessments 
comparing the pre-change and post-change product using comparative 
analytical, and, when necessary, animal and/or clinical (e.g., 
pharmacokinetic, immunogenicity) studies. A demonstration of 
comparability between pre- and post-change product supports a 
determination that the safety and efficacy profile remains the same for 
the product. With respect to interchangeable products, are there 
considerations in addition to comparability assessments that FDA should 
consider in regulating post-approval manufacturing changes of 
interchangeable products? Your comments should include the scientific 
rationale and justification for your recommendations, as well as 
recommendations for processes and systems (including key logistics) to 
implement your recommendations.
    2. As explained in the guidance ``Considerations in Demonstrating 
Interchangeability With a Reference Product,'' FDA expects that 
sponsors seeking an interchangeability determination will submit data 
and information to support a showing that the proposed interchangeable 
product can be expected to produce the same clinical result as the 
reference product in all of the reference product's licensed conditions 
of use. 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? Your comments should include the scientific 
rationale and justification for your recommendations, as well as 
recommendations for processes and systems (including key logistics) to 
implement your recommendations.

III. Paperwork Reduction Act of 1995

    This draft 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.
