Experimental drug

An experimental drug is a medicinal product (a drug or vaccine) that has not yet received approval from governmental regulatory authorities for routine use in human or veterinary medicine. A medicinal product may be approved for use in one disease or condition but still be considered experimental for other diseases or conditions.

In the United States, the body responsible for approval is the U.S. Food and Drug Administration (FDA), which must grant the substance Investigational New Drug (IND) status before it can be tested in human clinical trials. IND status requires the drug's sponsor to submit an IND application that includes data from laboratory and animal testing for safety and efficacy.[1] A drug that is made from a living organism or its products undergoes the same approval process but is called a biologics license application (BLA). Biological drugs include antibodies, interleukins, and vaccines.

If the clinical trial results show that therapeutic effect of the drug outweighs negative side effects then the sponsor cab then to file a New Drug Submission.[2]
