Investigational New Drug
Résumé
The United States Food and Drug Administration's Investigational New Drug (IND) program is the means by which a pharmaceutical company obtains permission to start human clinical trials and to ship an experimental drug across state lines (usually to clinical investigators) before a marketing application for the drug has been approved. Regulations are primarily at . Similar procedures are followed in the European Union, Japan, and Canada.
Commercial INDs are filed by companies to obtain marketing approval for a new drug.
Research or investigator INDs are non-commercial INDs filed by researchers to study an unapproved drug or to study an approved drug for a new indication or in a new patient population.
Emergency Use INDs, also called compassionate use or single-patient INDs, are filed for emergency use of an unapproved drug when the clinical situation does not allow sufficient time to submit an IND in accordance with 21 CFR §§ 312.23, 312.24. These are most commonly used for life-threatening conditions for which there is no standard treatment.
Treatment INDs are filed to make a drug available for the treatment of serious or immediately life-threatening conditions prior to FDA approval. Serious diseases or conditions are stroke, schizophrenia, rheumatoid arthritis, osteoarthritis, chronic depression, seizures, Alzheimer's dementia, amyotrophic lateral sclerosis (ALS), and narcolepsy.
Screening INDs are filed for multiple, closely related compounds in order to screen for the preferred compounds or formulations. The preferred compound can then be developed under a separate IND. Used for screening different salts, esters and other drug derivatives that are chemically different, but pharmacodynamically similar.
The IND application may be divided into the following categories:
Preclinical testing consists of animal pharmacology and toxicology studies to assess whether the drug is safe for testing in humans. Also included are any previous experience with the drug in humans (often foreign use).
