Medical Definition: Clinical Studies

Studies of new treatments in patients are known as clinical trials. A clinical trial is performed only when there is reason to believe that the new treatment may be beneficial for the patient. The main questions that researchers want to answer are: How effective is this treatment? Is it more effective than we are using now? What side effects does the treatment take? Are more benefits than risks? A doctor may suggest that a patient participating in a clinical trial. This does not mean you are being asked to be a human guinea pig. Nor does it mean that your case has no hope. However, there are some risks. No one knows in advance whether the treatment is effective, or exactly what side effects may occur. Keep in mind that even standard treatments have side effects.
