In this JCO Precision Oncology Article Insights episode, Miki Horiguchi provides a summary on “Clinical Trial Diversity: A Bend in the Arc Towards Justice”, by Tannenbaum, et al published on September 19, 2023 in JCO Precision Oncology. The editorial discusses the need for inclusion of under-represented groups in clinical trials.

Hello and welcome to JCO Precision Oncology Article Insights. I’m your host Miki Horiguchi, an ASCO Journals Editorial Fellow. Today, I will be providing a summary of the article titled “Clinical Trial Diversity: A Bend in the Arc Toward Justice” by Drs. Susan Tannenbaum and Jennifer Miller. This editorial accompanies the article “Representativeness of Patients Enrolled in the Lung Cancer Master Protocol (Lung-MAP)” by Dr. Vaidya and colleagues.
In the previous episode of this series, our Social Media Editor, Dr. Rafeh Naqash, interviewed Dr. Mary Redman, a Senior Author of the Lung-MAP article. Dr. Redman shared the background behind the Lung-MAP development, some highlights from her paper, and her career trajectory as a biostatistician. I strongly recommend listening to the interview if you haven’t done so. To begin I’ll provide a brief summary of the Lung-MAP information before discussing the editorial.
The Lung Cancer Master Protocol or Lung-MAP is a biomarker-driven master protocol that evaluates multiple molecularly targeted therapies for patients with advanced non-small cell lung cancers under a single trial infrastructure. Since Lung-MAP began enrolling patients in 2014, it has addressed the challenges of implementing precision medicine at oncology clinics and assuring equitable patient access to molecularly targeted therapies. In addition to meeting an unmet need in terms of treatment, Lung-MAP meets an unmet need in terms of accessibility to precision oncology clinical trials for all types of patients who get lung cancer in the United States. Specifically, Lung-MAP utilizes a public-private partnership that includes the National Cancer Institute’s National Clinical Trials Network, the SWOG Cancer Research Network, Friends of Cancer Research, the Foundation for the National Institutes of Health, Foundation Medicine, pharmaceutical companies, and lung cancer advocacy organizations. There are thousands of sites around the country that can offer Lung-MAP.
In the Lung-MAP article, the authors sought to examine whether Lung-MAP improves access to precision oncology clinical trials compared to conventional standalone trials. To this end, the authors compared accrual patterns by sociodemographic characteristics between Lung-MAP and a set of ten clinical trials for advanced non-small cell lung cancer conducted by the SWOG Cancer Research Network. The authors found that patients enrolled in Lung-MAP were more likely to be older, from rural or socioeconomically deprived areas, and with Medicaid or no insurance compared with conventional clinical trials. However, female patients and patients of Asian race or Hispanic ethnicity were underrepresented. The authors emphasized in their conclusion that further research examining participation barriers for underrepresented groups in precision oncology clinical trials is warranted.
In the associated editorial with the Lung-MAP article, Drs. Tannenbaum and Miller discuss some efforts to include diverse populations in clinical trials such as those of Lung-MAP and the continuing challenges we are facing.
The editorial begins with a striking example of an industry-funded trial, where pharmaceutical companies submitted a new drug for US Food and Drug Administration approval to treat patients with non-small cell lung cancer in the United States. However, the pivotal trial was conducted wholly in China, enrolling significantly younger patients than those with that type of cancer in the United States. There were no Black nor Hispanic-identifying patients and far more men than women in the trial. The product was not approved by the US FDA. Although the US FDA has approved many other products where the trials were unrepresentative , this example suggests that in order to capture elements in future patient populations in the United States, study samples need to include patients from under-represented groups as well.
The authors also introduced a recent study result that showed racially and ethnically under-represented patients, and their clinicians, are more likely to trust and use new medical products when the trials have enrolled a diverse population. This fact suggests that clinical trials that include a higher proportion of women and older adults, as well as patients from racially and ethnically under-represented groups, help to gain acceptance for the drug even after its approval.
The authors then introduced some efforts toward enhancing clinical trial diversity, including the National Institutes of Health Revitalization Act of 1993, the Institute of Medicine’s 2003 report, the US FDA’s 2020 guidance, and the innovative public-private collaboration of Lung-Map. While several studies suggested that clinical trials funded by the National Institute of Health have improved enrollment of patients from under-represented groups, industry-funded trials have still fallen short of these goals. Since industry-funded trials play a crucial role in developing novel drugs, industry must be held accountable for clinical trial diversity and make greater efforts to improve the situation. The authors introduced additional guidance toward this end. They include the US FDA’s 2022 new draft guidance to industry, recommending that sponsors of clinical trials submit a Race and Ethnicity Diversity Plan. Another is the Food and Drug Omnibus Reform Act of 2022 where the US FDA can require sponsors to have plans that include diverse populations in their clinical trials. These efforts are pivotal steps in the direction of making biomedical research more accessible and inclusive and lead to promoting health equity across the country.
