Clinical trials are studies that evaluate the effectiveness of new drugs or treatment strategies. The development of more effective cancer treatments requires that new and innovative therapies be evaluated with cancer patients. In oncology, clinical trials are especially important because, in the absence of high cure rates, nearly all therapeutic approaches are developmental in nature. All new cancer drugs that are currently available in the United States were once only available in clinical trials. Patients should decide whether or not participation in a clinical trial is an appropriate treatment option as early in their evaluation as possible because, once treatment of their cancer has been initiated, patients may become ineligible to participate in some clinical trials.
