Participation of Women in Clinical Trials for New Drugs Approved by the Food and Drug Administration in 2000–2002

Abstract

The percentages of women and men participating in clinical trials varied by year, phase, and product type. However, the overall participation by women and men was comparable, suggesting an improvement in including more women in clinical trials when compared with the previous FDA study evaluating women's participation from 1995 through 1999. As with the previous study, however, a significant underrepresentation of women in early phase trials and in certain areas, such as cardiovascular products, was observed and continues to be an issue of concern. Lack of appropriate analyses by sex should also be noted as an issue of concern.
