  1. What is an IND? Keith Wonnacott, Ph.D. Division of Cellular and Gene Therapies Office of Cellular, Tissue, and Gene Therapies Center for Biologics Evaluation and Research FDA

  2. Basis for Regulation of INDs • Statutes: THE LAW --- passed by Congress and signed by the President • 42 USC 262 (United States Code) • Regulations: details of the law --- written by the Agency and approved by the Executive Branch • 21 CFR 312 (Code of Federal Regulations) • Guidance: the Agency’s interpretation of the Regulations --- written and approved within the Agency • 68 FR 49488 (Federal Register)

  3. Drug and Biologics Law The following is a very brief history of the statutory basis for INDs

  4. Biologics Control Act 1901 13 children in St. Louis died of tetanus after receiving diphtheria antitoxin from a horse named Jim. 9 children die of tetanus from contaminated smallpox vaccine 1902 Biologics Control Act authorizes Hygienic Laboratory to issue regulations to ensure purity and safety of serums, vaccines, and similar products 1944 PHS Act incorporates provisions for biologics regulation. Outlines licensing requirements that are independent from pre-marketing requirements for drugs. 1973 Blood, blood products, and allergenics included in the PHS Act

  5. Food and Drug Act 1905 Samuel Hopkins Adams published “The Great American Fraud,” a commentary on the patent medicine industry exposing cure-all claims for worthless and dangerous patent medicines. Upton Sinclair publishes “The Jungle” with shocking disclosures of insanitary conditions in meat-packing plants. 1906 Food and Drug Actprohibits interstate commerce in misbranded and adulterated foods, drinks, and drugs.

  6. Food, Drug, and Cosmetic Act 1937 Sulfanilimide elixir containing diethylene glycol kills 107 people • Food, Drug, and Cosmetic Act required new drugs to be shown safe before marketing— starting a new system of drug regulation. It also authorized factory inspections and other provisions.

  7. Kefauver-Harris Amendments 1962 Thalidomide, a new sleeping pill, is found to have caused birth defects in thousands of babies born in western Europe. Over two million pills distributed in the United States for investigational studies. 1962 Kefauver-Harris Drug Amendments passed to ensure drug efficacy and greater drug safety. It required drug manufacturers to prove the effectiveness of their products before marketing them, gave FDA control over drug advertising, and allowed FDA to regulate investigational studies.

  8. Summary A new biologic, drug, or device may not be entered into interstate commerce unless: • It is approved by the FDA as safe and effective (biological license application [BLA], new drug application [NDA], pre-market approval [PMA], or other marketing approval) OR … • An IND is in effect (exempting the study from the premarketing approval requirements that are otherwise applicable)

  9. OR…

  10. Where do I find IND requirements? 21 CFR 312 Investigational New Drug Application

  11. PART 312 – INVESTIGATIONAL NEW DRUG APPLICATIONS • Subpart A – General provisions • Subpart B – IND application • Subpart C – Administrative action • Subpart D – Responsibilities of sponsors and investigators • Subpart E – Drugs intended to treat life-threatening and severely debilitating illnesses • Subpart F – Miscellaneous • Subpart G – Drugs for investigational use in laboratory research animals or in vitro tests

  12. PART 312 – INVESTIGATIONAL NEW DRUG APPLICATIONS • Subpart A – General provisions • Subpart B – IND application • Subpart C – Administrative action • Subpart D – Responsibilities of sponsors and investigators • Subpart E – Drugs intended to treat life-threatening and severely debilitating illnesses • Subpart F – Miscellaneous • Subpart G – Drugs for investigational use in laboratory research animals or in vitro tests

  13. When do I need an IND? • Anytime you are doing a clinical investigation with a drug or biologic EXCEPT…

  14. EXCEPT… If your study is: • An in vitro diagnostics used to confirm the results of an approved test • A study in animals • A placebo study not otherwise requiring an IND (not involving a drug or biologic)

  15. EXCEPT… If you are using an FDA approved product AND your study: • Is not intended to support a labeling or advertising change • Is administered so as not to increase the safety risk to the patients • Has institutional review board (IRB) approval • Follows the rules on charging for investigational drugs

  16. What are the phases of an investigation? Sponsor Perspective Marketing Preclinical Phase 1 Phase 2 Phase 3 Phase 4 Proof of concept, safety, potential toxicity, dosing strategy Post marketing commitments to monitor safety and efficacy Evaluate safety and side effects Evaluate safety and explore efficacy and dose ranging Obtain efficacy and safety data for approval IND filing BLA filing

  17. What are the phases of an investigation? Investigator Perspective Publication Preclinical Phase 1 Extend proof of concept to human Proof of concept IND filing

  18. What are the phases of an investigation? FDA Perspective Marketing Preclinical Phase 1 Phase 2 Phase 3 Phase 4 BLA review (6/10 months) IND review(30 days) End of Phase 2 Meeting Pre-IND Meeting Pre-BLA Meeting Amendment Review CONSULTATION

  19. How do I label an investigational drug? • “Caution: New Drug – Limited by Federal law to investigational use.” • No false or misleading claims • No statement that the drug is safe or effective for the indication for which it is being investigated

  20. Can I promote or charge for my investigational drug? • No promoting drug as safe or effective • No commercial distribution • No charging without the consent of the FDA • For clinical trials, FDA must give written consent after sponsor provides a full written explanation of why charging is necessary and not part of the normal cost of doing business 21 CFR 312.7(d)

  21. PART 312 – INVESTIGATIONAL NEW DRUG APPLICATIONS • Subpart A – General provisions • Subpart B – IND application • Subpart C – Administrative action • Subpart D – Responsibilities of sponsors and investigators • Subpart E – Drugs intended to treat life-threatening and severely debilitating illnesses • Subpart F – Miscellaneous • Subpart G – Drugs for investigational use in laboratory research animals or in vitro tests

  22. IND Checklist

  23. IND Checklist

  24. Introductory Statement/ General Investigational Plan • Description of the drug • Summary of previous human experience • Overall plan for investigating the drug

  25. IND Checklist

  26. Investigator’s Brochure • An investigators brochure contains information and instructions for investigators so that they can properly perform the study. • It is required if a commercial sponsor product is providing product to clinical investigators • It is not required for sponsor-investigators performing a trial at one clinical site
