guidance by June 24, 2019 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comment on this draft guidance before it begins work on the final 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    FDA is announcing the availability of a draft guidance for industry 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 ``Adjusting for Covariates in Randomized Clinical Trials for 
Drugs and Biologics with Continuous Outcomes.'' This guidance provides 
recommendations for the use of analysis of covariance (ANCOVA) in 
randomized clinical trials.
    The target population for a new drug or biologic usually includes 
individuals with diverse prognostic factors, and the population studied 
in clinical trials should reflect this diversity. However, baseline 
differences in prognostic factors impair the detection and estimation 
of treatment effects. Incorporating prognostic factors in the 
statistical analysis of clinical trial data can mitigate this 
impairment and can result in a more efficient use of data to 
demonstrate and quantify the effects of treatment. The International 
Council for Harmonisation guidance for industry entitled ``E9 
Statistical Principles for Clinical Trials'' briefly addresses these 
issues (https://www.fda.gov/downloads/drugs/guidancecomplianceregulatoryinformation/guidances/ucm073137.pdf). This 
guidance provides more detailed recommendations for the use of ANCOVA 
in randomized clinical trials.
    This draft guidance is being issued consistent with FDA's good 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 The draft guidance, when 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 ``Adjusting 
for Covariates in Randomized Clinical Trials for Drugs and Biologics 
with Continuous Outcomes.'' 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    This draft guidance refers to previously approved collections of 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). The 
collections of information in 21 CFR 312.23 for investigational new 
drug application content and format have been approved under OMB 
control number 0910-0014.

III. Electronic Access

    Persons with access to the internet may obtain the draft guidance 
at https://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm, https://www.fda.gov/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guidances/default.htm, or
