“I am pleased to announce the promotion of Dr. Urbanski to President and Chief Medical Officer. The combination of Ray’s experience as a practicing physician and subsequently experience in industry, where he has served in key leadership positions including serving as the Chief Medical Officer of one of Pfizer’s business units and as the Chief Medical Officer of Mylan. His training, depth of knowledge and experience as well as his organizational acumen has been invaluable as we prepare GT Biopharma for our next stage of growth,” said Shawn M. Cross, Chairman and Chief Executive Officer of GT Biopharma. “In addition to pushing forward our pre-clinical and clinical product candidates, Ray has played a critical role in advancing other company initiatives including recruiting experienced members to our scientific advisory board and board of directors, implementing internal processes and procedures, which are less visible but very important, as progress towards certain goals including a NASDAQ up-listing, among others. In short, I am delighted to have Ray as a senior member of our leadership team.”

Dr. Urbanski has also been a major factor in developing a strong working relationship with the University of Minnesota, Masonic Cancer Center, the epicenter of innovation for the TriKE and TetraKE platforms.
