The Clinical Trials Process
Before new drugs are approved by the Food and Drug Administration and made widely available, they must pass through a rigorous series of trials. Once a compound is identified in the laboratory as having potential therapeutic value, it is subjected to preclinical trials, which involve extensive laboratory and animal testing. The goal of these studies is to determine whether the compound is biologically active and safe.
If the compound proves effective in preclinical trials, human clinical testing can begin. Clinical trials are conducted in three phases.
are designed to test the drug's effectiveness. Simultaneous animal and human studies are also conducted to continue assessing the drug's safety.
