SUPPLEMENTARY INFORMATION: mstockstill on DSK4VPTVN1PROD with NOTICES I. Background On July 9, 2012, the President signed into law the Food and Drug Administration Safety and Innovation Act (FDASIA) (Pub. L. 112–144). Title I of FDASIA reauthorizes PDUFA and provides FDA with the user fee resources necessary to maintain an efficient review process for human drug and biological products. The reauthorization of PDUFA includes performance goals and procedures for the Agency that represent FDA’s commitments during fiscal years 2013– 2017. These commitments are fully described in the document entitled ‘‘PDUFA Reauthorization Performance Goals and Procedures Fiscal Years 2013 through 2017’’ (‘‘PDUFA Goals Letter’’), available on FDA’s Web site at https:// www.fda.gov/downloads/ForIndustry/ UserFees/PrescriptionDrugUserFee/ UCM270412.pdf. Section IX of the PDUFA Goals Letter, titled ‘‘Enhancing Regulatory Science and Expediting Drug Development,’’ includes an enhancement to advance the science of meta-analysis methodologies. As part of this enhancement, FDA committed to hold a public meeting to engage stakeholders in a discussion of current and emerging scientific approaches and methods for the conduct of metaanalyses and to facilitate stakeholder input regarding the use of meta-analyses in FDA’s regulatory review process. The public meeting announced by this notice will fulfill this commitment. II. Purpose and Scope of the Meeting The objectives of the meeting are to: 1. Initiate constructive discussion and information-sharing about best practices in meta-analyses of clinical trial data that can be used to evaluate potential drug risks while limiting spurious findings, 2. Share current experience regarding the criteria considered by FDA to be important in making regulatory decisions when evaluating the strength and quality of evidence provided by a meta-analysis, and 3. Obtain input on specific issues identified by FDA on procedures, methods, and potential sources of bias in the design, conduct and use of metaanalysis. Although many external stakeholders conduct meta-analyses, FDA’s use of meta-analyses and other safety evaluation tools has the potential to result in consequential regulatory actions, including market withdrawal or concluding that a safety concern is not VerDate Mar<15>2010 17:25 Oct 23, 2013 Jkt 232001 supported by data. As a result, FDA must adopt a rigorous approach to these analyses and be transparent regarding its evidentiary standards and how it weighs the evidence of a meta-analysis in arriving at a decision or regulatory action. The public meeting will focus on meta-analyses conducted for purposes of safety evaluation using data from RCTs. FDA acknowledges that meta-analyses conducted to evaluate a product’s effectiveness, either overall or within specific subgroups, are occasionally of interest to the Agency, but the primary use of meta-analyses in the regulatory setting is for the assessment of product risk. Furthermore, although metaanalyses of non-randomized studies may be informative for the assessment of certain safety endpoints, the issues related to such a meta-analysis are not the focus of the meeting. FDA expects that this meeting will build upon prior stakeholder feedback on the design, conduct, and assessment of meta-analyses obtained at the ‘‘DIA/ FDA Best Practices for Regulatory Information Synthesis of Randomized Controlled Trials for Product Safety Evaluation’’ workshop held on March 10 and 11, 2011, in Bethesda, MD. The public input from the meeting will be used to develop a draft guidance describing best practices for the conduct and use of meta-analyses of randomized controlled trials for the evaluation of risks associated with the use of human drugs or biological products within the framework of regulatory decisionmaking. The future guidance will be intended for FDA reviewers, the pharmaceutical industry, and for thirdparty entities that prepare or evaluate meta-analyses to assess the safety of regulated products, as there is currently no FDA guidance in this area. Specifically, this guidance will describe FDA’s view of various aspects of the criteria considered important when evaluating the strength and quality of evidence provided by a meta-analysis. To facilitate discussions at the public meeting, FDA is publishing a white paper on considerations in the conduct and use of meta-analyses of RCTs that are intended to support regulatory decisionmaking about a product’s safety. This document is available on FDA’s Web site at https://www.fda.gov/ ForIndustry/UserFees/ PrescriptionDrugUserFee/ ucm360080.htm. III. Scope of Public Input Requested FDA seeks input on a range of topics related to the design and conduct of meta-analyses and the interpretation of meta-analysis results when evaluating PO 00000 Frm 00033 Fmt 4703 Sfmt 4703 risk in the regulation of pharmaceutical products. These include the following: 1. Potential sources of bias that may arise in designing a meta-analysis, including: a. Advance or prior knowledge of individual study results and their influence on study selection. b. Lack of or inadequate prespecification of the meta-analysis hypothesis. c. Inclusion of the hypothesisgenerating study in the meta-analysis designed to confirm the hypothesis. d. Other sources of bias that may exist but cannot be identified. 2. Potential for spurious findings because of the examination of multiple hypotheses, endpoints, and subgroups, and use of data driven analyses, in a meta-analysis. 3. Methodological issues in the conduct of the meta-analysis, including the following: a. The use of fixed versus random effects models in evaluating a metaanalytic hypothesis, especially with regard to individual and overall study power, study heterogeneity, and generalizability. b. The relative value of the use of frequentist versus Bayesian methods for meta-analyses. c. The choice of statistical levels of uncertainty of the results, including the significance level for the primary and secondary hypotheses. d. The most appropriate methods to incorporate studies with few events and those with no events. 4. Issues related to the individual studies constituting a meta-analysis, including: a. Measures of individual study quality, including availability of protocols and amendments. b. Outcome and exposure ascertainment in each study. c. The use of patient-level versus study-level data. 5. Issues related to the overall quality of the meta-analysis, including the following: a. Whether there is adequate documentation of the pre-specification and proper conduct of a meta-analysis, and more generally, how researchers should document their methods, including the important issues of prespecification, in support of their proper conduct of a meta-analysis. b. Use and pre-specification of the types of sensitivity analyses to evaluate the impact of various sources of bias (see section III.1) on the meta-analysis findings. c. Evaluating the results of a metaanalysis when one or a few large studies dominate the findings (often recognized before the analysis).

SUPPLEMENTARY INFORMATION:

I. Background

    On July 9, 2012, the President signed into law the Food and Drug 
Administration Safety and Innovation Act (FDASIA) (Pub. L. 112-144). 
Title I of FDASIA reauthorizes PDUFA and provides FDA with the user fee 
resources necessary to maintain an efficient review process for human 
drug and biological products. The reauthorization of PDUFA includes 
performance goals and procedures for the Agency that represent FDA's 
commitments during fiscal years 2013-2017. These commitments are fully 
described in the document entitled ``PDUFA Reauthorization Performance 
Goals and Procedures Fiscal Years 2013 through 2017'' (``PDUFA Goals 
Letter''), available on FDA's Web site at https://www.fda.gov/downloads/ForIndustry/UserFees/PrescriptionDrugUserFee/UCM270412.pdf. Section IX 
of the PDUFA Goals Letter, titled ``Enhancing Regulatory Science and 
Expediting Drug Development,'' includes an enhancement to advance the 
science of meta-analysis methodologies. As part of this enhancement, 
FDA committed to hold a public meeting to engage stakeholders in a 
discussion of current and emerging scientific approaches and methods 
for the conduct of meta-analyses and to facilitate stakeholder input 
regarding the use of meta-analyses in FDA's regulatory review process. 
The public meeting announced by this notice will fulfill this 
commitment.

II. Purpose and Scope of the Meeting

    The objectives of the meeting are to:
    1. Initiate constructive discussion and information-sharing about 
best practices in meta-analyses of clinical trial data that can be used 
to evaluate potential drug risks while limiting spurious findings,
    2. Share current experience regarding the criteria considered by 
FDA to be important in making regulatory decisions when evaluating the 
strength and quality of evidence provided by a meta-analysis, and
    3. Obtain input on specific issues identified by FDA on procedures, 
methods, and potential sources of bias in the design, conduct and use 
of meta-analysis.
    Although many external stakeholders conduct meta-analyses, FDA's 
use of meta-analyses and other safety evaluation tools has the 
potential to result in consequential regulatory actions, including 
market withdrawal or concluding that a safety concern is not supported 
by data. As a result, FDA must adopt a rigorous approach to these 
analyses and be transparent regarding its evidentiary standards and how 
it weighs the evidence of a meta-analysis in arriving at a decision or 
regulatory action. The public meeting will focus on meta-analyses 
conducted for purposes of safety evaluation using data from RCTs.
    FDA acknowledges that meta-analyses conducted to evaluate a 
product's effectiveness, either overall or within specific subgroups, 
are occasionally of interest to the Agency, but the primary use of 
meta-analyses in the regulatory setting is for the assessment of 
product risk. Furthermore, although meta-analyses of non-randomized 
studies may be informative for the assessment of certain safety 
endpoints, the issues related to such a meta-analysis are not the focus 
of the meeting.
    FDA expects that this meeting will build upon prior stakeholder 
feedback on the design, conduct, and assessment of meta-analyses 
obtained at the ``DIA/FDA Best Practices for Regulatory Information 
Synthesis of Randomized Controlled Trials for Product Safety 
Evaluation'' workshop held on March 10 and 11, 2011, in Bethesda, MD.
    The public input from the meeting will be used to develop a draft 
guidance describing best practices for the conduct and use of meta-
analyses of randomized controlled trials for the evaluation of risks 
associated with the use of human drugs or biological products within 
the framework of regulatory decisionmaking. The future guidance will be 
intended for FDA reviewers, the pharmaceutical industry, and for third-
party entities that prepare or evaluate meta-analyses to assess the 
safety of regulated products, as there is currently no FDA guidance in 
this area. Specifically, this guidance will describe FDA's view of 
various aspects of the criteria considered important when evaluating 
the strength and quality of evidence provided by a meta-analysis.
    To facilitate discussions at the public meeting, FDA is publishing 
a white paper on considerations in the conduct and use of meta-analyses 
of RCTs that are intended to support regulatory decisionmaking about a 
product's safety. This document is available on FDA's Web site at 
https://www.fda.gov/ForIndustry/UserFees/PrescriptionDrugUserFee/ucm360080.htm.

III. Scope of Public Input Requested

    FDA seeks input on a range of topics related to the design and 
conduct of meta-analyses and the interpretation of meta-analysis 
results when evaluating risk in the regulation of pharmaceutical 
products. These include the following:
    1. Potential sources of bias that may arise in designing a meta-
analysis, including:
    a. Advance or prior knowledge of individual study results and their 
influence on study selection.
    b. Lack of or inadequate pre-specification of the meta-analysis 
hypothesis.
    c. Inclusion of the hypothesis-generating study in the meta-
analysis designed to confirm the hypothesis.
    d. Other sources of bias that may exist but cannot be identified.
    2. Potential for spurious findings because of the examination of 
multiple hypotheses, endpoints, and subgroups, and use of data driven 
analyses, in a meta-analysis.
    3. Methodological issues in the conduct of the meta-analysis, 
including the following:
    a. The use of fixed versus random effects models in evaluating a 
meta-analytic hypothesis, especially with regard to individual and 
overall study power, study heterogeneity, and generalizability.
    b. The relative value of the use of frequentist versus Bayesian 
methods for meta-analyses.
    c. The choice of statistical levels of uncertainty of the results, 
including the significance level for the primary and secondary 
hypotheses.
    d. The most appropriate methods to incorporate studies with few 
events and those with no events.
    4. Issues related to the individual studies constituting a meta-
analysis, including:
    a. Measures of individual study quality, including availability of 
protocols and amendments.
    b. Outcome and exposure ascertainment in each study.
    c. The use of patient-level versus study-level data.
    5. Issues related to the overall quality of the meta-analysis, 
including the following:
    a. Whether there is adequate documentation of the pre-specification 
and proper conduct of a meta-analysis, and more generally, how 
researchers should document their methods, including the important 
issues of pre-specification, in support of their proper conduct of a 
meta-analysis.
    b. Use and pre-specification of the types of sensitivity analyses 
to evaluate the impact of various sources of bias (see section III.1) 
on the meta-analysis findings.
    c. Evaluating the results of a meta-analysis when one or a few 
large studies dominate the findings (often recognized before the 
analysis).

    d. The overall framework to evaluate the quality of the meta-
analysis; whether there is a basis for establishing a hierarchy of 
evidence for judging the quality of the meta-analysis.
