The clinical research field is crucial in pharmaceutical research and development, working closely with the clinical trials field to investigate the safety of new medications, surgeries, and techniques. It involves recruiting human volunteers of various ages, health statuses, genders, and geographical regions to test new drugs and translate the basic research into new treatments. Testing on a more significant number of volunteers confirms the drug's safety before reaching millions of people.
Clinical researchers must follow strict clinical study protocols. There are two basic types of research: observational and clinical trials. Observational studies aim to identify and analyze medical data patterns, while clinical trials, conducted in five phases, assess the safety and effectiveness of new drugs.
