FDA’s Mission
FDA has a broad public protection mission
Ensure the safe use of regulated products
that are themselves safe and efficacious
Underlying this mission is FDA decisionmaking on product applications and labeling
Based on complete and accurate information from
well-designed, ethically-conducted, and wellmonitored clinical research
FDA’s Mission in Clinical
Research
Ensure Implementation of Good Clinical
Practice Standards
Embodied in FDA regulation and guidance
since the 1960’s and ‘70’s
International Standard (ICH E6) since 1996
Enforced through FDA’s review process and
in its program of on-site inspections
U.S. Clinical Investigator inspections from 1962
Ethics Committee (IRB) inspections from 1978
International CI inspections from 1980
GCP is Comprehensive
International ethical and scientific quality
standard for designing, conducting,
recording, and reporting trials that involve
the participation of human subjects
GCP embraces trial objectives, trial design,
study oversight, data collection and quality
assurance, study analysis, as well as human
subject protection in studies that support
product applications
Good Clinical Practice
GCP is most fundamentally a System of
Shared Responsibilities
Clinical Investigators
Institutions/Institutional Review Boards
Industry (Sponsors/Monitors)
Government Regulators
FDA’s Authority to Regulate
Federal Food Drug and Cosmetic Act
Requires that an FDA approved
marketing or research permit be
obtained before certain commodities
(such as human drugs, medical devices,
veterinary drugs, food additives, etc.)
may move across state lines
Pharmaceuticals may move
across state lines during two
stages of human use
Research prior to “approval”
Requires research permit: e.g,
Investigational New Drug Exemption (IND)
Marketing after “approval”
Requires marketing permit: e.g., New Drug
Application (NDA)
What is an IND/IDE ?
An exemption from the law which
otherwise requires that a drug (biologic,
device) be approved before it can be
transported across state lines
The standard for approval is evidence of
safety and efficacy
The IND exemption is granted for purposes
of clinical investigation (research)
Importance of the IND
Affirms a body of knowledge about the
manufacturing, pharmacology, and
toxicology of the drug to support its use in
human testing
Requires that the clinical investigation(s) be
performed in accordance with Good Clinical
Practice (GCP)
Provides an additional level of protection
through FDA oversight
The FD&C Act Defines
“Drug” Very Broadly
Any of:
Article recognized in the U.S. Pharmacopeia,
official Homeopathic Pharmacopeia of the US,
or official National Formulary, or any
supplement
Article intended for use in the diagnosis,
cure, mitigation, treatment, or prevention of
disease in man or other animals
The FD&C Act Defines
“Drug” Very Broadly
Any of:
Article (other than food) intended to
affect the structure or any function of
the body of man or other animals
Article intended for use as a component of
any article specified in clauses above
Section 201(g) of the FD&C Act
“Clinical Investigation” is
also Defined Broadly
Any experiment in which a drug is
administered or dispensed to, or used
involving, one or more human subjects.
For the purposes of this part, an
experiment is any use of a drug except
for the use of a marketed drug in the
course of medical practice
21 CFR 312.3
So When Is an IND
Required ?
In general: An IND is required when
an unapproved drug (or biologic) is
used in a clinical investigation
What About Approved
Products
No IND is needed when an approved
product is used in the course of medical
practice (even for an indication different
from the approved indication)
But an IND may be required when an
approved products is used in a clinical
investigation
What About Approved
Products
An IND is needed if:
The clinical investigation is intended to be
reported to FDA as a well-controlled study
in support of a new indication or a
significant change in the labeling of the
drug
The clinical investigation is intended to
support a significant change in advertising
for the product
What About Approved
Products
With the above caveats, clinical
investigation of an approved product may
be exempt from IND requirements if:
The investigation does not involve a route of
administration or dosage level or use in a
patient population or other factor that
significantly increases risks AND
The investigation is conducted in accordance
with IRB and informed consent requirements
What About Approved
Products
FDA has generally allowed the IRB to
assess whether risk of an approved
product is increased for a given protocol
But FDA retains final authority for such
determinations
What About Approved
Products
It is also important to note that shelf
chemicals which bear the same “name”
as an approved product are not
considered as “lawfully marketed”
equivalents of the approved product
Approval is specific to dose, formulation,
and applicant

Sponsor Responsibilities
Selecting Qualified Investigators
Providing investigators with information they need to
conduct an investigation properly.
Ensuring proper monitoring of the investigation(s)
Conduct per protocol
Ethical considerations
Control of investigational product(s)
Safety reporting
Sponsor Responsibilities
Review Ongoing Investigations
A sponsor who discovers that an investigator is
not complying with the signed 1572, general
investigation plan, or regulations shall promptly
either:
secure compliance or
end the investigator’s participation in the
investigation (discontinue shipment and
require return/disposal of drug; notify FDA).
Sponsor-Investigators
FDA regulations allow an individual to be
both study sponsor and clinical
investigator
The Dilemma:
Many sponsor-investigators believe that the
lack of external monitoring and oversight
means that they can perform to a lower
standard
Sponsor-Investigators
The Dilemma -2Where a sponsor and an investigator are the
same, the number of GCP control points is
reduced from four to three
A sponsor-investigator therefore needs to be
more (not less) informed of responsibilities
and more attentive to standards of study
conduct and subject protection
Subject Education
Subject Education is an often neglected
facet of GCP; yet, an educated, fully
informed, and inquiring subject may be
the best resource for ensuring ethical and
quality performance in a clinical trial
The IRB and institution should pay
particular attention to informing subjects
where to go with questions or complaints
Reporting to FDA
Sponsors are required to report serious
non-compliance
But anyone can report complaints in FDAregulated clinical trials to FDA
FDA’s GCP website (www.fda.gov/oc/gcp)
highlights where to report complaints in
clinical trials
New At FDA
FDA has recently established a new
Office for Good Clinical Practice to
coordinate GCP across FDA and
beyond...

Clinical Trial QA:
What We Should Strive For
Building quality in upfront
Assuring quality throughout
Developing capacity for continuous
quality improvement now and in the
future
Working Together:
Plentiful Opportunities
Well-designed, well-conducted clinical
trials are not easy
If you don’t want to “do it right”, you
should not be conducting clinical trials
The best systems can only emerge
from the broadest possible
participation
