clinical research studies

At New West Physicians, we have been conducting clinical research studies for our patients since 1997. Our research clinic is located in Golden and is directed by our Chief Medical Officer, Ken Cohen, MD.  Dr. Cohen works with several pharmaceutical companies and selectively chooses clinical studies that he feels will be the best for our patients while still advancing medical research for new medicines. All studies are approved by the Food and Drug Administration (FDA) and conducted by our experienced and caring research team. To learn more about how clinical research studies work, visit
