A clinical research study is used to advance treatments or prevent medical conditions and diseases. Doctors, researchers, and scientists conduct clinical research in phases.
Each phase of a clinical research study is designed to provide different information about a new treatment, such as the safety, dose and how well the treatment or medication works. The phases are described as I, II, III, and IV.
When one is thinking about participating in a clinical research study, it is vital to be well-educated in the clinical trials phases of clinical research studies.
There are 4 clinical trials phases of clinical research studies: Phase 1 which is when the medication is being tested for the very first time in healthy adults for safety, dosage, and possible side effects.
Phase 2 which is done in a bigger group is testing for how effective the medication is as well as if there are other methods of delivery.
Phase 3 is after there is even more information and even less of a risk; the medication is tested on adults and children to compare the medication to an already approved alternative of the medication.
And finally Phase 4 which is the final stage in which the medication has already been approved by the FDA and data collecting is then used for research and collecting information on the long term use of said medication.
There have been various kinds of clinical research studies done and there are many examples. The most common clinical research study is vaccine studies that help discover treatments for new or existing diseases that will result in improving the health of the future.
It is important when doing clinical research that all studies are done according to protocol and safety guidelines and the CRO is successful at completing the studies as well as ensuring the safety and health of its patients through all clinical trials phases.
