A clinical trial is a research study to answer specific questions about vaccines or new therapies or new ways of using known treatments. Clinical Trials also called medical research and research studies] are used to determine whether new drugs or treatments are both safe and effective. Carefully conducted clinical trials are the fastest and safest way to find treatments that work. Leads for clinical trials usually come from researchers. Once researchers test new therapies or procedures in the laboratory [animal studies] and get promising results, they begin planning Phase I clinical trials [in humans].New therapies are tested on people only after laboratory and animal studies show promising results. Clinical Trials make it possible to apply the latest scientific and technological advances to patient care. When a new medical treatment is studied for the first time in humans, it is not known exactly how it will work. With any new treatment, there are possible risks as well as benefits
