Women remain underrepresented in leading cardiovascular clinical trials, which corresponds with underrepresentation and a lack of gender diversity among presenters at scientific meetings, according to a review published Feb. 28 in the Journal of the American College of Cardiology (JACC).

A previous analysis of cardiovascular trials published over the last four years found that women comprised only 10.1% of clinical trial leadership committees, and more than half of the trials had no women as part of the trial leadership team. Other research has also found a correlation between women leading clinical trials and the number of women participating in clinical trials. Historically, clinical trials have largely enrolled white men, and participation has been low among women, older adults and racial/ethnic minorities. The current review highlights gender diversity of panelists and session chairs at recent ACC Scientific Sessions, but notes that 93% of the clinical trial results were presented by men.

“These problems are, unfortunately, cyclical in nature. A lack of women in leadership positions on clinical trials results in fewer women participating in the trials. The fewer women participating in studies means that medications and other therapies aren’t ensured to be safe and effective for everyone,” said Mary Norine Walsh, MD, MACC, author of the paper. “Fewer women leading clinical trials also means fewer women presenting pivotal, practice-changing trial results at scientific meetings.”

Walsh explains that increasing the number of women on trial steering committees needs to start at a deeper level. Mentorship in early career is crucial as is knowledge of clinical trial committee structure. To help ensure this, medical societies have begun to release recommendations and roadmaps to foster change, including ACC’s “Clinical Trial Research: Upping Your Game” program, designed to help develop and train the next generation of women and underrepresented minorities as clinical trialists. In addition, ACC’s Women in Cardiology Leadership Council and Diversity and Inclusion Task Force recently published the JACC article, “10 Recommendations to Enhance Recruitment, Retention, and Career Advancement of Women Cardiologists.”

“We’re starting to see work being done to close the gap in representation, but more needs to be done,” Walsh said. “Scientific sessions and meeting planners only have so much influence over who is presenting at conferences. This comes down to senior clinical trialists relinquishing the podium and giving a leg up to others.”

Walsh lays out steps to increase representation in clinical trial leadership, including:

• Federal and industry sponsors of clinical trials insisting on diversity of the trial steering committee
• Investigators considering geographic, institutional and trial site diversity, along with a diverse slate of experienced investigators in leadership positions
• Institutions, department chairs and division chiefs encouraging women to serve as site principal investigators
• Reworking the informal, or formal, pecking order of cardiovascular trial leadership
• The understanding that women should not be tapped for clinical trial leadership, and late-breaking results reporting, solely if the trial is pertinent only to a female patient population

“There will be no room at the top for new and innovative investigators to shine if those who have already achieved success don’t make room,” Walsh concludes.
