pg.4 Investigational New Drug (IND) Application Except under very limited circumstances, FDA requires data from clinical trials—formally designed, conducted, and analyzed studies of human subjects—to provide evidence of a drug’s safety and effectiveness. Before testing in humans—called clinical testing—the drug’s sponsor (usually its manufacturer) must file an investigational new drug (IND) application with FDA. The IND includes information about the proposed clinical study design, completed animal test data, and the lead investigator’s qualifications. It must also include the written approval of an Institutional Review Board, which has determined that the study participants will be made aware of the drug’s investigative status and that any risk of harm will be necessary, explained, and minimized. The application must include an “Indication for Use” section that describes what the drug does and the clinical condition and population for which the manufacturer intends its use. Trial subjects should be representative of that population. The FDA has 30 days to review an IND application. Unless FDA objects, a manufacturer may then begin clinical testing. Clinical Trials With IND status, researchers test in a small number of human volunteers the safety they had demonstrated in animals. These trials, called Phase I clinical trials, attempt, in FDA’s words, “to determine dosing, document how a drug is metabolized and excreted, and identify acute side effects.” If the sponsor considers the product still worthy of investment, it continues with Phase II and Phase III clinical trials. Those trials gather evidence of the drug’s efficacy and effectiveness in larger groups of individuals with the particular characteristic, condition, or disease of interest, while continuing to monitor safet http://www.fas.org/sgp/crs/misc/R41983.pdf
