Investigational Drugs and Devices (IND/IDE) Overview. As defined by the Food and Drug Administration (FDA), an IND, or investigational new drug application, is a request for authorization from the FDA to administer an investigational drug or biological product to humans.
Treatment use of an investigational drug is conditioned on the sponsor and investigators complying with the safeguards of the IND process, including the regulations governing informed consent (21 CFR part 50) and institutional review boards (21 CFR part 56) and the applicable provisions of part 312, including distribution of the drug through qualified experts, maintenance of adequate manufacturing facilities, and submission of IND safety reports.
