Clinical Trial and Clinical Research
Clinical trials are experiments or observations done in clinical research? Such prospective biomedical or behavioral research studies on human participants are designed to answer specific questions or behavioral interventions, including new treatments such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices and known interventions that warrant further study and comparison. Clinical trials generate data on safety and efficacy. They are conducted only after they have received the health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial – their approval does not mean the therapy is safe or effective, only that the the trial may be conducted.
