Minorities Are Underrepresented in Clinical Trials of Pharmaceutical Agents for Cystic Fibrosis.

Although CF disproportionately affects non-Latino white individuals, members of other racial or ethnic groups are proportionally underrepresented in CF pharmacology clinical trials. Inadequate inclusion of minorities and failure to report the racial or ethnic background of study subjects limits information about factors influencing drug response and may contribute to health disparities for minorities with CF.
