Knepper TC, McLeod HL. When will clinical trials finally reflect diversity? Nature 2018;557:157-159

For this reason, funders and researchers have repeatedly said that clinical trials should include more participants from ethnic minorities. An analysis of drug studies shows that most participants are white, even though trials are being done in more countries.
