Women’s Participation in Clinical Trials

OWH advocates for participation of women in clinical trials and the analyses of data by sex. 

  • Adequate participation of women in clinical trials allows representation of the population most likely to use a disease therapy.
  • Analyzing data by sex allows researchers to determine if there are any sex differences in a disease therapy.
  • Sex differences can include differences in disease prevalence and response.
  • Analyses for sex differences can provide insight into the scientific basis for individual therapy differences and provide future directions for research.

OWH R&D program supports studies to track participation of women in clinical trials and collaborate with FDA centers to understand sex and gender differences in disease prevalence and response to therapy through science and research. FDA Center collaborations contribute towards the development of MaPPs, guidances and regulations to advance women’s health.
