Clinical trials are well designed, organized studies designed to test new therapies.
Every aspect of a new treatment needs to be comprehensively evaluated at every phase of development prior to release for general use. For instance, a new drug may be studied to learn the optimum dose, to study side effects or to evaluate its effectiveness against a specific cancer. These are necessary details about new treatments that are needed to establish the safety profile of the drugs and whether they work effectively. This process allows innovative, investigational therapy to become standard treatments. All modern medical advances have endured clinical trials as a way of proving that they are safe and effective.
