Clinical trials are conducted in a healthcare setting (a hospital or clinic) and are typically monitored by a trained healthcare professional. An Institutional Review Board or IRB approves all clinical trials. This is a committee made up of doctors, ethicists, members of the general public and administrators. This group is held responsible for agreeing that a trial does not represent an unreasonable risk to patients who are participating. Trials are also reviewed by the FDA. Your doctor is responsible for your well-being and is the best person to decide whether or not you are eligible to participate in a trial.
