Clinical Trial Diversity Planning

Design and execute more inclusive trials with a suite of end-to-end services

Implement a comprehensive clinical trial diversity plan that addresses regulatory needs while avoiding risk to trial timelines.

the challenge

The time for action is now.

For decades, many groups of individuals have been underrepresented in clinical trials, including racial, ethnic, age, gender, and social groups.

This omission hinders our grasp of how treatments work across different populations, worsening cancer care inequities and outcomes for historically marginalized communities.

The FDA’s 2022 guidance now requires sponsors to create diversity action plans, mandating representative testing for therapies. To facilitate this, the FDA urges sponsors to leverage diverse data sources, emphasizing real-world data. Sponsors need comprehensive datasets, time for analysis, effective decision-making tools, and access to diverse enrollment sites, aligning with FDA standards. Failure to promptly develop and execute these plans could lead to trial delays or costly post-marketing commitments.
