FDA Research, Policy, and Workshops on Women in Clinical Trials

Clinical trials provide a critical base of evidence for evaluating whether a medical product is effective before the product is approved for marketing. Women’s participation in clinical trials has improved in many areas, but we need to continue this momentum. The FDA Office of Women’s Health (OWH) was established by congressional mandate to advocate for the participation of women in clinical trials and the analyses of data by sex. OWH supports studies to track the participation of women in clinical trials and collaborates with FDA's centers and external partners to conduct trainings, workshops, outreach, and research to improve clinical trials design, recruitment, and analyses and to support FDA regulatory policy and decision-making.

Why is this work so important?

  • 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 the response to medical treatment.

  • Analyses for sex differences can provide insight into the scientific basis for individual therapy differences and provide future directions for research.  

FDA Activities

FDA Guidance, Regulations and Reports

FDA has a variety of statutory, regulatory, and policy-related tools that provide a framework for guiding medical product sponsors in the inclusion and analysis of women and demographic subgroups in clinical trials.

Conferences and Scientific Workshops

 

OWH Sex and Gender Speaker Series for FDA Reviewers

The FDA Office of Women’s Health established a new CE lecture series for FDA reviewers to provide the latest evidence about sex differences in disease presentation, treatment, and outcomes. Launched in March 2016, the series features scientific developments and regulatory best practices in sex and gender-specific women’s health.
