What are the different types of clinical trials that I can participate in?


Interventional trials (also called treatment trials) determine whether new treatments, new combination of drugs, new ways of using known therapies or new approaches to surgery or radiation therapy are safe and effective. These trials might ask a participant to take an experimental new drug or undergo surgery.
Prevention trials look for better ways to prevent disease in people who have never had the disease or to prevent a disease from returning. These approaches may include medicines, vitamins, vaccines, minerals, or lifestyle changes.
Observational trials address health issues in large groups of people. Trial participants may be asked to answer questions about their family histories or give blood samples, but they do not receive treatment for their diseases.
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 a chronic illness.
Diagnostic trials refer to trials that are conducted to find better tests or procedures for
diagnosing a particular disease or condition. Diagnostic trials usually include people who have signs or symptoms of the disease or condition being studied.
