“IDDI performed an excellent job on the data management, IWRS and EDC functions for our large phase 2 study, and the statistical work was outstanding. The statistical group was extremely responsive and flexible, and despite the time difference between the U.S and Belgium the process was seamless and the response was extremely fast, even when the workload was very demanding. The output from the statistical group was meticulous and precise during a period of very ambitious timelines”.
