The IND Process David A. Lepay, M.D., Ph.D. Senior Advisor for Clinical Science Office of the Commissioner, US FDA Johns Hopkins Program December 10, 2001
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 decision-making on product applications and labeling • Based on complete and accurate information from well-designed, ethically-conducted, and well-monitored 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 FDA-regulated 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...
