Clinical Research

What is Clinical Research?

Clinical research is the process through which medications are evaluated and approved for use in the treatment of various medical conditions. All medications must pass through prolonged, rigorous testing prior to their approval by the Food and Drug Administration (FDA) for prescription use in the U.S. In order to obtain such approval, pharmaceutical companies select physicians to recruit patients that have specific diagnoses and are willing to participate in testing of the new medication. Hence, clinical pharmacology research offers patients the opportunity to experience the effects of new drugs prior to their release to the general public.

Gwinnett Clinical Research Center was founded in 1981 and has participated in over 225 clinical trials. Some of the major advancements in dermatologic therapy have resulted from this process and helped many patients prior to availability to the general public. The Research Center, located in our Snellville office, is owned and operated by Dr. Joel S. Shavin and Dr. Jonathan S. Weiss. They are assisted by two Research Coordinators. All studies are conducted under the guidelines of Good Clinical Practices (GCPs), under Institutional Review Board (IRB) oversight, and according to the rules and regulations of the FDA.
