Statistical Approaches To Evaluate Analytical Similarity; Draft 
Guidance for Industry; Availability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the availability of a draft guidance for industry entitled 
``Statistical Approaches to Evaluate Analytical Similarity.'' This 
draft guidance, when finalized, will provide advice on the evaluation 
of analytical similarity to sponsors interested in developing 
biosimilar products. Specifically, this draft guidance describes the 
type of information a sponsor of a proposed biosimilar product should 
obtain about the structural/physicochemical and functional attributes 
of the reference product, how that information is used in the 
development of an analytical similarity assessment plan for the 
proposed biosimilar, and the statistical approaches recommended for 
evaluating analytical similarity.

DATES: Submit either electronic or written comments on the draft 
guidance by November 21, 2017 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

ADDRESSES: You may submit comments on any guidance at any time as 
follows:

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Statistical Approaches to Evaluate Analytical Similarity.'' 
This draft guidance, when finalized, will provide advice on the 
evaluation of analytical similarity to sponsors interested in 
developing biosimilar products for licensure under section 351(k) of 
the Public Health Service Act (PHS Act) (42 U.S.C. 262(k)). This 
evaluation is performed to support a demonstration that the proposed 
biosimilar is highly similar to a reference product licensed under 
section 351(a) of the PHS Act.
    Specifically, this draft guidance, when finalized, will describe 
the type of information that the sponsor of a proposed biosimilar 
product should obtain about the structural/physicochemical and 
functional attributes of the reference product, how that information is 
used in the development of an analytical similarity assessment plan for 
the proposed biosimilar, and the statistical approaches recommended for 
evaluating analytical similarity.
    The Biologics Price Competition and Innovation Act of 2009 (BPCI 
Act) created an abbreviated licensure pathway under section 351(k) of 
the PHS Act for biological products shown to be biosimilar to or 
interchangeable with a U.S.-licensed biological reference product (see 
sections 7001 through 7003 of Pub. L. 111-148). As described in section 
351(k)(2)(A)(i)(I)(aa) of the PHS Act, an application for a proposed 
biosimilar product must include information demonstrating biosimilarity 
based on data derived from, among other things, ``analytical studies 
that demonstrate that the biological product is highly similar to the 
reference product notwithstanding minor differences in clinically 
inactive components.''
    This draft guidance is one in a series of guidance documents 
intended to implement the BPCI Act. It serves as a companion document 
to the guidance for industry entitled ``Quality Considerations in 
Demonstrating Biosimilarity of a Therapeutic Protein Product to a 
Reference Product'' (April 30, 2015, 80 FR 24257). The Quality 
Considerations guidance describes the Agency's recommendations to 
sponsors on the scientific and technical information, including the 
analytical studies to support a demonstration that a proposed 
biosimilar is highly similar to the U.S.-licensed reference product, 
for the chemistry, manufacturing, and controls section of a marketing 
application for a proposed biosimilar product.
    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 statistical 
approaches to evaluating analytical similarity. 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 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). This 
includes information collections related to: (1) The submission of an 
investigational new drug application, which is covered under 21 CFR 
part 312 and approved under OMB control number 0910-0014; (2) the 
submission of a new drug application, which is covered under 21 CFR 
314.50 and approved under OMB control number 0910-0001; (3) the 
submission of 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; and (4) meetings between FDA and 
applicants or sponsors of a biologics license application under section 
351(k) of the PHS Act, which is approved under OMB control number 0910-
0802.
