CRG, or Clinical Research Group, is an organization focused on conducting clinical trials and research studies to evaluate new medical treatments and therapies. These groups often collaborate with hospitals, universities, and pharmaceutical companies to ensure that new drugs and procedures are safe and effective for patients. The primary goal of CRG is to advance medical knowledge and improve patient care by gathering data from clinical studies. This information helps regulatory bodies, like the Food and Drug Administration (FDA), make informed decisions about the approval and use of new medical products.
