The objective of this initiative was to develop an effective contract for multi-site studies launched by sponsors. This optimized process will allow sites to participate earlier in the clinical trial process, without unnecessary delays in contract negotiations. Phase 0 and Phase I studies are looking for healthy volunteers. Most other clinical trials look for patients who have a particular disease or medical condition. The diversity observed in society should be reflected in clinical trials through the adequate inclusion of ethnic minorities.  Patient recruitment or participant recruitment plays an important role in the activities and responsibilities of sites conducting clinical trials.
