There are 4 phases of biomedical clinical trials:   Phase I studies usually test new drugs for the primary time during a small group of individuals to guage a secure dosage range and identify side effects. Phase II studies test treatments that are found to be safe in phase I clinical trial but now need a bigger group of human subjects to watch for any adverse effects. Phase III studies are conducted on larger populations and in several regions and countries, and are often the step right before a replacement treatment is approved. Phase IV studies take place after country approval and there is a need for further testing in a wide population over a longer time frame. Clinical trials are a sort of medical research that follow an outlined protocol that has been carefully developed to answer a selected patient care question.
