It's a scientific experiment
Before a potential treatment can get to our families, it has to go through a clinical trial. A clinical trial is a scientific experiment. It is not a medical treatment. In a clinical trial for a potential therapy, a drug that has been thoroughly investigated in the laboratory (for example in a test tube or mouse) is tested in human beings for safety and efficacy. Drug developers must provide data to the Food and Drug Administration (FDA), or its counterpart in other countries, compelling evidence that the drug is safe enough for its intended use and delivers a therapeutic benefit.
