We have a great concern for the human condition. That’s why physicians are constantly look for better or new ways of treating illness and disease. Research as resulted in large numbers of discoveries, but those discoveries cannot be put into general use until controlled evaluations have been completed with actual patients. Clinical trials are the only scientifically valid way that these evaluations can be completed. The Food and Drug Administration (FDA) requires carefully monitored and well-controlled clinical trials before it can approve a new treatment as safe and effective for public use. Clinical trials are the link between research and the relief of human suffering.
