BIOETHICS IN CLINICAL RESEARCH

Clinical trials are experiments done in clinical research. Such prospective biomedical or behavioural research studies on human participants are designed to answer specific questions about biomedical or behavioural 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 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 that the therapy is 'safe' or effective only that the trial may be conducted.
