[Docket No. 97D-0100]
Guidance for Industry on Providing Clinical Evidence of
Effectiveness for Human Drugs and Biological Products; Availability
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is announcing the
availability of a guidance for industry entitled ``Providing Clinical
Evidence of Effectiveness for Human Drug and Biological Products.'' The
purpose of this guidance is to clarify what clinical evidence of
effectiveness should be provided in new drug applications, biological
product license applications, and supplemental applications for new
uses of drugs and biologics. The guidance is also intended to fulfill
the requirements of certain provisions of the Food and Drug
Administration Modernization Act of 1997 (the Modernization Act).
DATES: General comments on agency guidance documents are welcome at any
time.
ADDRESSES: An electronic version of this guidance is available via the
Internet at http://www.fda.gov/cder/guidance/index.htm and at http://
www.fda.gov/cber/guidelines.htm. Submit written comments on this
guidance to the Dockets Management Branch (HFA-305), Food and Drug
Administration, 12420 Parklawn Dr., rm. 1-23, Rockville, MD 20857.
Comments are to be identified with the docket number found in brackets
in the heading of this document.
FOR FURTHER INFORMATION CONTACT: Joseph P. Griffin, Center for Drug
Evaluation and Research (HFD-5), Food and Drug Administration, 5600
Fishers Lane, Rockville, MD 20857, 301-594-5400.
SUPPLEMENTARY INFORMATION: The draft guidance for industry entitled
``Providing Clinical Evidence of Effectiveness for Human Drug and
Biological Products'' (the draft guidance) was initially developed as
part of an effort to get more information about valid uses of marketed
drugs into the labeling of these drugs. Uncertainty on the part of the
industry about the evidentiary requirements for demonstrating
effectiveness for a supplemental indication was believed to be an
obstacle to sponsors submitting applications for supplemental
indications. The draft guidance was intended to clarify the amount and
types of evidence that could be used to demonstrate effectiveness and
thereby facilitate submission of additional supplemental applications.
In the Federal Register of March 21, 1997 (62 FR 13650), FDA announced
the availability of the draft guidance. The notice gave interested
persons an opportunity to submit comments by May 20, 1997.
On November 21, 1997, the President signed the Modernization Act
(Pub. L. 105-115), which addressed both the standards for providing
clinical evidence of effectiveness and the evidentiary requirements for
supplemental applications. Section 115 of the Modernization Act amended
the definition of substantial evidence in section 505(d) of the Federal
Food,
[[Page 27094]]
Drug, and Cosmetic Act (the act) (21 U.S.C. 355(d)) to clarify that
FDA, at its discretion, may make exception to the general requirement
that there must be more than one adequate and well-controlled
investigation to support an effectiveness determination. Section 115 of
the Modernization Act provides in relevant part that ``[i]f the
[agency] determines, based on relevant science, that data from one
adequate and well-controlled clinical investigation and confirmatory
evidence (obtained prior to or after such investigation) are sufficient
to establish effectiveness, the [agency] may consider such data and
evidence to constitute substantial evidence [of effectiveness].''
In clarifying the standard for substantial evidence, Congress
acknowledged the agency's position that there have been major advances
in the science and practice of clinical drug development since the
effectiveness requirement was added to the act in 1962, and confirmed
FDA's interpretation of the substantial evidence of effectiveness
standard, as explained in the draft guidance document.
In addition to the provision on the evidence standard, the
Modernization Act included section 403, ``Approval of Supplemental
Applications for Approved Products.'' Section 403(a) of the
Modernization Act requires FDA to publish in the Federal Register,
within 180 days of enactment, standards for the prompt review of
supplemental applications for drugs and biological products. These
standards are included in a guidance document for which a notice of
availability is published elsewhere in this issue of the Federal
Register.
Section 403(b) of the Modernization Act requires that FDA, within
180 days of enactment, issue final guidances to clarify the
requirements for, and facilitate the submission of data to support, the
approval of supplemental applications for drugs and biologics. The
guidance issued today fulfills this statutory requirement as it
addresses the data requirements for both original drug and biological
product applications and supplements to those applications.
In addition, section 403(b)(1) of the Modernization Act requires
that FDA provide guidance to ``clarify circumstances in which published
matter may be the basis for approval of a supplemental application.''
Section III of the guidance describes the circumstances in which a
sponsor may rely in part, or entirely, on published reports of studies
to support approval of a supplemental application.
Section 403(b)(2) of the Modernization Act requires that FDA
provide guidance to ``specify data requirements that will avoid
duplication of previously submitted data by recognizing the
availability of data previously submitted in support of an original
application.'' Section II of the guidance describes a range of
circumstances in which existing data, whether or not previously
submitted to an original application, may be used to support an
application for a supplemental indication, thus permitting a sponsor to
avoid developing unnecessary additional data.
The agency received 13 submissions commenting on the draft
guidance, including comments from pharmaceutical and biological
products companies and their trade associations, individuals and
organizations in academic medicine and clinical pharmacology, patient
advocacy organizations, and a consumer. The response to the draft
guidance was generally favorable. The guidance was viewed as a
significant step forward by the agency in clarifying and better
articulating its quantitative and qualitative evidentiary standards for
evidence of effectiveness. Comments observed that the principles
espoused were scientifically reasonable, practical, and appropriately
flexible. The agency has considered all of the comments in making
revisions to the guidance document.
This guidance document is being issued as a Level 1 guidance
consistent with FDA's good guidance practices (62 FR 8961, February 27,
1997). It represents the agency's current thinking on clinical evidence
of effectiveness for human drug and biological products. It does not
create or confer any rights for or on any person and does not operate
to bind FDA or the public. An alternative approach may be used if such
approach satisfies the requirements of the applicable statute,
regulations, or both.
Submit written requests for single copies of the guidance for
industry entitled ``Providing Clinical Evidence of Effectiveness for
Human Drug and Biological Products'' to the Drug Information Branch
(HFD-210), Center for Drug Evaluation and Research, Food and Drug
Administration, 5600 Fishers Lane, Rockville, MD 20857; or the Office
of Communication, Training and Manufacturers Assistance (HFM-40),
Center for Biologics Evaluation and Research (CBER), Food and Drug
Administration, 1401 Rockville Pike, Rockville, MD 20852-1448. Please
send one self-addressed adhesive label to assist the offices in
processing your request. The document may also be obtained by mail by
calling the CBER Voice Information System at 1-800-835-4709 or 301-827-
1800, or by fax by calling the CBER FAX Information System at 1-888-
CBERFAX or 301-827-3844.
Interested persons may at any time submit written comments on the
guidance to the Dockets Management Branch (address above). Requests and
comments should be identified with the docket number found in brackets
