In April 2022, FDA issued new draft guidance on Diversity Plans to Improve Enrollment of Participants from Underrepresented Racial and Ethnic Subgroups in Clinical Trials. Because this guidance applies to all medical products, CDER, CBER, and CDRH all contributed, but this draft was led by Project Equity from FDA’s Oncology Center of Excellence (OCE). “It is important that we be able to evaluate new therapies in the context of a diverse population that will use these medical products because the diseases for which these products are intended present in variable fashion across the population and because populations respond variably to medical products,” explains OCE Project Equity Lead Lola Fashoyin-Aje. “But we should reconsider the question regarding why diversity in clinical trials is important. Because the question really ought to be: What are we missing when trials are not diverse, when the study population in the clinical trial is not diverse? What are the missed opportunities for advancing science or advancing clinical medicine and, ultimately, for driving improvements in population outcomes?”
