required in clinical research until
30 years later,
we’re still decades
out of clinical research?
Until 1993, women weren’t required in U.S. research for cancer, heart disease, Alzheimer’s, diabetes, vaccines, prescription drugs, mental health conditions, and much more.1
On June 10, 1993,
Congress passed the NIH Revitalization Act, requiring the inclusion of women in clinical research for the first time.
In 1977, a Food and Drug Administration policy recommended excluding "women of childbearing potential" from Phase I and early Phase II drug trials.
This was partly a safety measure after the use of thalidomide to treat morning sickness in the 1950s unknowingly caused thousands of birth defects. Even though thalidomide was never approved for use in the U.S. for anyone, after what happened, researchers thought it was safest not to include any women of childbearing age in studies.
However, researchers also had biased concerns that female hormone fluctuations made women too “difficult” to study and made research more expensive.
Because of those reasons, women and people with vaginas were not just left out but actively excluded from U.S. clinical research from 1977 to 1993.
But on June 10, 2023, we still haven’t reached parity.
And without equal research, there can never be equal care.
While some strides have been made since 1993, particularly with the representation of white women, there are many groups that remain under-represented — including women from non-white racial and ethnic communities.
Additionally, older adults, pregnant and lactating people, people from the LGBTQIA+ community, and people with disabilities remain under-represented and even excluded from clinical research.
At Evvy, we're pioneering precision healthcare for women and people with vaginas by discovering and leveraging overlooked biomarkers, starting with the vaginal microbiome.
We’re normally focused on destigmatizing vaginal health and providing clinical care for the vaginal microbiome, but our larger mission is to build a world where our health is finally understood, where medical bias has no place, and where everyone works together to close the gender health gap.
