Definition:
A scientifically designed and executed investigation of the effects of a drug (or vaccine) administered to human subjects. The goal is to define the safety, clinical efficacy, and pharmacological effects (including toxicity, side effects, incompatibilities, or interactions) of the drug. The U.S. government, through the Food and Drug Administration (FDA), requires strict testing of all new drugs and vaccines prior to their approval for use as therapeutic agents.
