[Docket No. FDA-2016-D-4460]

Multiple Endpoints in Clinical Trials; Draft Guidance for 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the availability of a draft guidance for industry entitled ``Multiple 
Endpoints in Clinical Trials.'' This draft guidance provides sponsors 
and review staff with the Agency's thinking about the problems posed by 
multiple endpoints in the analysis and interpretation of study results 
and how these problems can be managed in clinical trials for human 
drugs, including drugs subject to licensing as biological products. 
Most clinical trials performed in drug development contain multiple 
endpoints to assess the effects of the drug and to document the ability 
of the drug to favorably affect one or more disease characteristics. 
The purpose of this guidance is to describe various strategies for 
grouping and ordering endpoints for analysis and applying some well-
recognized statistical methods for managing multiplicity within a study 
to control the chance of making erroneous conclusions about a drug's 
effects.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
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draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by March 14, 2017.

will be available for public viewing and posted on http://www.regulations.gov. Submit both copies to the Division of Dockets 
Management. If you do not wish your name and contact information to be 
made publicly available, you can provide this information on the cover 
sheet and not in the body of your comments and you must identify this 
information as ``confidential.'' Any information marked as 
``confidential'' will not be disclosed except in accordance with 21 CFR 
10.20 and other applicable disclosure law. For more information about 
FDA's posting of comments to public dockets, see 80 FR 56469, September

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Multiple Endpoints in Clinical Trials.'' This guidance 
describes various strategies for grouping and ordering endpoints for 
analysis and applying some well-recognized statistical methods for 
managing multiplicity within a study. FDA's International Conference on 
Harmonization (ICH) guidance for industry ``E9 Statistical Principles 
for Clinical Trials'' is a broad-ranging guidance that includes 
discussion of multiple endpoints. This draft guidance provides greater 
detail on the topic of multiple endpoints. The issuance of this draft 
guidance represents partial fulfillment of an FDA commitment under the 
Food and Drug Administration Amendments Act of 2007. (Title I of the 
Food and Drug Administration Amendments Act of 2007 (Pub. L. 110-85)). 
Under section XI (Expediting Drug Development) of the Prescription Drug 
User Fee Act (PDUFA) Performance Goals, FDA agreed to develop and 
publish for comment draft guidance on ``Multiple Endpoints in Clinical 
Trials,'' and to complete the final guidance within one year of the 
close of the public comment period of the PDUFA Performance Goals (see 
http://www.fda.gov/ForIndustry/UserFees/PrescriptionDrugUserFee/ucm119243.htm).
    Failure to account for multiplicity when there are several clinical 
endpoints evaluated in a study can lead to false positive conclusions 
regarding the effects of the drug. The regulatory concern regarding 
multiplicity arises principally in the evaluation of clinical trials 
intended to demonstrate effectiveness and support drug approval; 
however, this issue is important throughout the drug development 
process.
    The focus of this draft guidance is control of the Type 1 error 
rate for the planned primary and secondary endpoints of a clinical 
trial so that the major findings are well supported. Multiplicity 
adjustments provide a means for controlling Type 1 error when there are 
multiple analyses of the drug's effects. The issues of multiplicity and 
methods to address them are illustrated in the draft guidance with 
examples of different study endpoints. Both the issues and methods that 
apply to multiple endpoints also apply to other sources of 
multiplicity, including multiple doses, time points, or study 
population subgroups.
    Once a trial is successful (demonstrates effectiveness or ``wins'' 
on the primary endpoint(s)), there are many other attributes of a 
drug's effects that may be described. Analyses that describe these 
other attributes of a drug can be informative and are often included in 
physician labeling. Such descriptive analyses are not the subject of 
this draft guidance and are not addressed in detail.
    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 multiple 
endpoints in clinical trials. 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.
