Researchers at two California universities reviewed pivotal clinical trials done between 2017 and 2023. They found that only a small share of trials used to approve new drugs reflect the United States racial and ethnic makeup. Enrollment of Black and Hispanic people fell from 2021, while Asian participation rose and white participation stayed mainly steady.
The study notes many trials follow International Council for Harmonisation standards and take place in a few regions. It says much of Africa and large parts of Latin America are rarely included. The authors recommend setting diversity goals early, choosing testing locations to match local needs, and collecting biological samples to study drug responses.
