Race reporting and diversity in US food and drug administration (FDA) registration trials for prostate cancer; 2006-2020.

We found a significant under-representation of non-white participants in FDA drug registration trials for PCa. Race reporting in licensing publication is inconsistent and both FDA and International Committee of Medical Journal Editors guidelines are not being universally followed. Given the disproportionality of the disease burden of PCa, recruitment of Black and other minority participants to trials should be a research priority.
