Are clinical trials not diverse right now?

Most people who take part in clinical trials are white or Caucasian. Non-white minorities make up less than 10% of all clinical trial participants. This is a problem because some minority groups get certain diseases more often. For example, African American men are twice as likely as white men to die from prostate cancer. However, African American men only make up 4% of men in prostate cancer clinical trials. Because of this, treatments for prostate cancer may not work as well for African American men.
