Researchers say therapy improves stem cell engraftment in umbilical cord blood transplant recipients

 "There is a significant need to improve the speed and quality of engraftment of cord-derived stem cells," says trial leader Corey Cutler, MD, MPH, of Dana-Farber and Brigham and Women's Hospital. "FT1050 has shown the ability in preclinical research to activate hematopoetic [blood-forming] stem cells so they engraft more quickly and with a higher degree of success."

The goal of the phase I trial was to assess the safety of FT1050-treated cord blood cells in adult patients receiving umbilical cord blood stem cell transplants, and determine if the treated cells accelerate engraftment. In the 12 patients who participated in the trial, engraftment occurred approximately three to four days faster than happens with standard cord blood cells. Levels of white blood cells known as neutrophils returned to normal in the patients after a median of 17.5 days, similar to the rate in standard stem cell transplants. Side effects of the FT1050-treated cord blood cells were minimal. In none of the study patients did the stem cells fail to engraft.
