What is a Clinical Trial?
A clinical trial (also clinical research) is a research study in human volunteers to answer specific health questions. Carefully conducted clinical trials are the fastest and safest way to find treatments that work in people and ways to improve health. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings. Why Participate in a Clinical Trial?

A clinical trial is a research study to answer specific questions about new therapies or new ways of using known treatments. Clinical trials (also called medical research and research studies) are used to determine whether new drugs or treatments are both safe and effective. Carefully conducted clinical trials are the fastest and safest way to find treatments that work in people.
In cancer research, a clinical trial is a study conducted with cancer patients, usually to evaluate a new treatment. Each study is designed to answer scientific questions and to find new and better ways to help cancer patients. The search for good cancer treatments begin with basic research in laboratory and animal studies. The best results of that research are tried in patient studies, hopefully leading to findings that may help many people. Before a new treatment is tried with patients, it is carefully studied in the laboratory. This research points out the new methods most likely to succeed and, as much as possible, shows how to use them safely and effectively. But this early research cannot predict exactly how a new treatment will work with patients. With any new treatment there may be risks as well as possible benefits. There may also be some risks that are not yet known. Clinical trials help us find out if a promising new treatment is safe and effective for patients. During a tri
