Clinical Trials

In the battle against devastating diseases such as cancer, a major effort is the development and testing of new tactics: surgeries, drugs, radiation therapies, preventive therapies and combinations of those that might lead to a cure. Clinical trials — scientific studies that test the effectiveness of a treatment, device, or drug — contribute to finding new and better ways of treating diseases. For example, a trial may test the effectiveness of blood pressure medication or whether a certain drug can lower cholesterol.
