The majority of clinical trials are therapeutic, offering new treatments to those who have advanced diseases such as late-stage cancer. Some are adjuvant, such as those testing hormones to prevent the recurrence of breast cancer. Prevention trials test agents that may help reduce the likelihood of developing diseases for those at high risk. In translational trials, researchers examine a patient’s genes to determine what genetic makeup responds best to particular treatments. Observational trials address health issues in large groups of people of populations in natural settings.
