In 1962, Congress required for the first time that new drugs be shown to be effective as well as safe. A new drug’s effectiveness must be established by substantial evidence. FDA has interpreted this substantial evidence requirement as generally requiring two adequate and well-controlled clinical investigations, each convincing on its own, to establish effectiveness. In 1997, Congress amended section 505(d) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355(d)) to make clear that FDA may consider data from one adequate and well-controlled investigation and confirmatory evidence to constitute substantial evidence if FDA determines that such data are sufficient to establish effectiveness. FDA issued the 1998 Effectiveness guidance in response to this legislative change. In 2019, the Agency concluded that more guidance was needed on the flexibility in the amount and type of evidence needed to meet the substantial evidence standard and issued the 2019 Effectiveness draft guidance, which discussed a number of approaches that can yield evidence that meets the statutory standard for substantial evidence. Although both the 1998 Effectiveness guidance and the 2019 Effectiveness draft guidance provide examples of how a single adequate and well-controlled clinical investigation and confirmatory evidence can be used to support a marketing application, these guidances are not intended to provide a comprehensive discussion of meeting the substantial evidence standard based on one adequate and well-controlled clinical investigation and confirmatory evidence. Thus, there is a need for more Agency guidance to describe how one adequate and well-controlled clinical investigation and confirmatory evidence can be used to meet the substantial evidence requirement. When one adequate and wellcontrolled clinical investigation and confirmatory evidence are considered together to assess effectiveness, the quality and quantity of the confirmatory evidence are also important considerations. Confirmatory evidence should be evidence generated from quality data derived from an appropriate source. The quantity of confirmatory evidence needed in a development program will be impacted by the features of, and results from, the single adequate and well-controlled clinical VerDate Sep<11>2014 18:21 Sep 18, 2023 Jkt 259001 investigation that the confirmatory evidence is intended to substantiate. This draft guidance describes these considerations in greater detail. It also provides examples of the types of evidence that could be considered confirmatory evidence that can be used with one adequate and well-controlled clinical investigation to demonstrate substantial evidence of effectiveness. Finally, the draft guidance includes recommendations for early engagement with the Agency for sponsors who intend to establish substantial evidence of effectiveness with one adequate and well-controlled clinical investigation and confirmatory evidence. 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 ‘‘Demonstrating Substantial Evidence of Effectiveness Based on One Adequate and Well-Controlled Clinical Investigation and Confirmatory Evidence.’’ 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.

The previously approved collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501–3521).

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Demonstrating Substantial Evidence of Effectiveness Based on 
One Adequate and Well-Controlled Clinical Investigation and 
Confirmatory Evidence.'' This guidance complements the 2019 draft 
guidance entitled ``Demonstrating Substantial Evidence of Effectiveness 
for Human Drug and

[[Page 64446]]

Biological Products'' issued on December 20, 2019 (84 FR 70196) and the 
1998 guidance entitled ``Providing Clinical Evidence of Effectiveness 
for Human Drug and Biological Products'' issued on May 15, 1998 (63 FR 
27093).
    In 1962, Congress required for the first time that new drugs be 
shown to be effective as well as safe. A new drug's effectiveness must 
be established by substantial evidence. FDA has interpreted this 
substantial evidence requirement as generally requiring two adequate 
and well-controlled clinical investigations, each convincing on its 
own, to establish effectiveness.
    In 1997, Congress amended section 505(d) of the Federal Food, Drug, 
and Cosmetic Act (FD&C Act) (21 U.S.C. 355(d)) to make clear that FDA 
may consider data from one adequate and well-controlled investigation 
and confirmatory evidence to constitute substantial evidence if FDA 
determines that such data are sufficient to establish effectiveness. 
FDA issued the 1998 Effectiveness guidance in response to this 
legislative change. In 2019, the Agency concluded that more guidance 
was needed on the flexibility in the amount and type of evidence needed 
to meet the substantial evidence standard and issued the 2019 
Effectiveness draft guidance, which discussed a number of approaches 
that can yield evidence that meets the statutory standard for 
substantial evidence.
    Although both the 1998 Effectiveness guidance and the 2019 
Effectiveness draft guidance provide examples of how a single adequate 
and well-controlled clinical investigation and confirmatory evidence 
can be used to support a marketing application, these guidances are not 
intended to provide a comprehensive discussion of meeting the 
substantial evidence standard based on one adequate and well-controlled 
clinical investigation and confirmatory evidence. Thus, there is a need 
for more Agency guidance to describe how one adequate and well-
controlled clinical investigation and confirmatory evidence can be used 
to meet the substantial evidence requirement.
    When one adequate and well-controlled clinical investigation and 
confirmatory evidence are considered together to assess effectiveness, 
the quality and quantity of the confirmatory evidence are also 
important considerations. Confirmatory evidence should be evidence 
generated from quality data derived from an appropriate source. The 
quantity of confirmatory evidence needed in a development program will 
be impacted by the features of, and results from, the single adequate 
and well-controlled clinical investigation that the confirmatory 
evidence is intended to substantiate.
    This draft guidance describes these considerations in greater 
detail. It also provides examples of the types of evidence that could 
be considered confirmatory evidence that can be used with one adequate 
and well-controlled clinical investigation to demonstrate substantial 
evidence of effectiveness. Finally, the draft guidance includes 
recommendations for early engagement with the Agency for sponsors who 
intend to establish substantial evidence of effectiveness with one 
adequate and well-controlled clinical investigation and confirmatory 
evidence.
    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 
``Demonstrating Substantial Evidence of Effectiveness Based on One 
Adequate and Well-Controlled Clinical Investigation and Confirmatory 
Evidence.'' 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

    While this guidance contains no new collection of information, it 
does refer to previously approved FDA collections of information. The 
previously approved collections of information are subject to review by 
the Office of Management and Budget (OMB) under the Paperwork Reduction 
Act of 1995 (PRA) (44 U.S.C. 3501-3521). The collections of information 
in 21 CFR parts 58, 312, 314, and 601 have been approved under OMB 
control numbers 0910-0119, 0910-0014, 0910-0001, and 0910-0338, 
respectively. In addition, the collections of information pertaining to 
FDA's guidance entitled ``Formal Meetings Between the FDA and Sponsors 
or Applicants of PDUFA Products'' have been approved under OMB control 
number 0910-0001.
