Clinical Trials - General Information

What is a Clinical Trial?

Clinical trials test new ways to prevent, diagnose or treat diseases. They test investigational medical devices and medicinal products or explore new ways of using existing treatments, such as investigational drugs, vaccines, surgical procedures and radiation techniques or combinations of different treatments. Based on the results of clinical trials, scientists can evaluate investigational treatments in relation to safety and effectiveness (whether it works better than existing methods). Clinical trials are also often referred to as clinical studies, medical research trials or simply trials. Most of the pharmaceuticals that we use today can be traced back to the results of clinical trials conducted in the past.
