Clinical trials are research studies that involve testing new drugs, treatments, medical devices, or procedures on human participants to determine their safety, efficacy, and potential side effects. These trials are conducted to evaluate the effectiveness of a new intervention compared to standard treatments or a placebo, and to gather data on the treatment's benefits and risks. Clinical trials are essential for advancing medical knowledge and improving patient care by providing evidence-based information on the best ways to prevent, diagnose, and treat diseases. Participants in clinical trials may benefit from access to cutting-edge treatments, expert medical care, and close monitoring of their health.
