Development of clinical trial diversity plans for regulatory submission involves careful setting of enrollment targets based upon current prevalence data, not just historical enrollment numbers, and multiple approaches for assessing whether diversity goals are being achieved.

Industry and academic experts discussed establishment of clinical study enrollment goals and use of disease prevalence data, as well as potential measures for incentivizing enrollment of more diverse populations, at a recent workshop sponsored by

Key Takeaways
