What types of research are being conducted in clinical trials?
• Treatment trials test investigational treatments, new combinations of drugs, or new approaches to surgery or radiation therapy. • Prevention trials look for better ways to prevent a given disease from occurring in people who have never had the disease or prevent the disease from returning. These approaches may include medicines, vitamins, vaccines, minerals or lifestyle changes. • Diagnostic trials are conducted to find better medical tests or procedures for diagnosing a particular disease or medical condition. • Screening trials test the best way to detect certain diseases or health conditions. • Quality of life trials (or supportive-care trials) explore ways to improve comfort and the quality of life for individuals with chronic illnesses.
