This guidance is intended to assist submitters of a biomarker for qualification that conduct nonclinical biomarker qualification studies in which histopathology is used as a reference or truth standard. This guidance discusses the processes that we recommend be considered when generating histopathology data to be included in biomarker studies and outlines the scientific standards recommended for histopathology used in nonclinical biomarker characterization and qualification. The recommendations in this guidance are intended for confirmatory studies in nonclinical biomarker qualification that justify the proposed context of use, where scientifically rigorous evaluation of biomarker performance in relation to histopathologic changes is essential.

Considerations for Use of Histopathology and Its Associated 
Methodologies To Support Biomarker Qualification; Guidance for 
Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

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

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a guidance for industry entitled ``Considerations for 
Use of Histopathology and Its Associated Methodologies to Support 
Biomarker Qualification.'' This guidance is intended to assist 
submitters of a biomarker for qualification that conduct nonclinical 
biomarker qualification studies in which histopathology is used as a 
reference or truth standard. This guidance discusses the processes that 
we recommend be considered when generating histopathology data to be 
included in biomarker studies and outlines the scientific standards 
recommended for histopathology used in nonclinical biomarker 
characterization and qualification. The recommendations in this 
guidance are intended for confirmatory studies in nonclinical biomarker 
qualification that justify the proposed context of use, where 
scientifically rigorous evaluation of biomarker performance in relation 
to histopathologic changes is essential. The principles outlined in 
this guidance are also applicable to exploratory nonclinical biomarker 
studies. This guidance finalizes the draft guidance ``Use of Histology 
in Biomarker Qualification Studies,'' issued in December 2011.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Considerations for Use of Histopathology and Its Associated 
Methodologies to Support Biomarker Qualification.'' The FDA Critical 
Path Initiative identified the discovery, characterization, 
qualification, and use of biomarkers as important for improving the 
efficiency and success rate of medical product development. Biomarkers 
have been broadly applied to describe the following:
     Structural features from the molecular to the anatomic 
level (e.g., genetic composition, receptor expression patterns, 
radiographic appearances);
     Biochemical measurements (e.g., serum levels of 
electrolytes, cardiac troponins); and
     Physiologic organ system function tests (e.g., creatinine 
clearance, pulmonary function tests, cardiac ejection fraction, 
electrocardiography).
    The type of study reports to be submitted in support of a biomarker 
qualification will depend upon the proposed context of use and the 
ultimate goal of the submission. The proposed context of use dictates 
the depth, extent, and rigor of the supporting data for the biomarker. 
If a biomarker becomes qualified, analytically valid measurements of it 
can be relied upon to have a specific and interpretable meaning (e.g., 
physiologic, toxicologic, pharmacologic, or clinical) in drug 
development and regulatory decision-making. Industry can then employ 
the biomarker for the qualified context of use during premarketing drug 
development, and FDA reviewers can be confident about its qualified 
context of use without the need to reconfirm its applicability or 
utility. Accordingly, data supporting qualification of a nonclinical 
biomarker should be reliable, repeatable, and of assured integrity.
    In the Federal Register of December 30, 2011 (76 FR 82306), FDA 
announced the availability of a draft guidance entitled ``Use of 
Histology in Biomarker Qualification Studies.'' The Agency received 
several comments from the pharmaceutical industry and others. We have 
carefully considered the comments and have made the following changes 
in response to the comments: (1) Changed the title of the guidance to 
``Considerations for Use of Histopathology and Its Associated 
Methodologies to Support Biomarker Qualification''; (2) clarified the 
scope of the guidance; (3) added more information concerning data used 
to support biomarker qualification; (4) confirmed and clarified the 
rationale for assessment of outcomes without knowledge of group 
assignments in confirmatory studies; and (5) clarified the distinction 
between biomarker sensitivity and specificity. In addition we have made 
editorial changes to improve clarity. This guidance finalizes the draft 
guidance issued in December 2011.
    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 for the use of histopathology 
and its associated methodologies to support biomarker qualification. 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.

II. Paperwork Reduction Act of 1995

    This guidance contains information collection provisions that are 
subject to review by the Office of Management and Budget (OMB) under

collections of information in this guidance were approved under OMB 
control numbers 0910-0001 for submissions related to 21 CFR 314, and 
0910-0014 for submissions related to 21 CFR 312.
