Inspired to Reduce Cancer Disparities and Help Those in Need


Dr. Samer Al Hadidi treats patients with myeloma and other plasma cell disorders. He joined the University of Arkansas for Medical Science’s Myeloma Center in the Winthrop P. Rockefeller Cancer Institute in 2022 and also serves as an assistant professor in the UAMS College of Medicine’s Department of Hematology and Oncology.

Al Hadidi completed his fellowship in hematology/oncology from Baylor College of Medicine in Houston, where he focused on cell and gene therapy. He completed his residency in internal medicine at Michigan State University in Flint and received a master’s degree in clinical research and statistical analysis from the University of Michigan in Ann Arbor. He received his medical degree from the University of Jordanin Amman.

While in training in Flint, Michigan, he encountered many patients with limited resources, which affected their access to therapy and treatment. He has focused on studying and researching health disparities among Black patients and other minorities for the past six years.

Al Hadidi and his colleagues recently published, “Geographic and Racial Disparities in Access to Chimeric Antigen Receptor-T Cells and Bispecific Antibodies Trials for Multiple Myeloma” in JAMA Network Open. They examined whether there is equitable geographic access to chimeric antigen receptor T cells (CAR-T) and bispecific antibodies trials for patients with myeloma in the United States. This is crucial because many patients with myeloma are Black.

Findings from this cross-sectional study of data from 69 clinical trials in the United States showed that 34% of the states analyzed had no CAR-T or bispecific clinical trial openings and that there are limited open sites in states with the highest percentages of Black residents. These results suggest that the current CAR-T and bispecific antibodies trials for myeloma do not offer equitable access for Black patients.

This is just the latest of many examples of Al Hadidi’s research focusing on health equity among minorities. Blacks individuals are at more than twice the risk of developing myeloma and more likely to receive a diagnosis at a younger age.

Long before this study, Al Hadidi was an author on papers of population-based research on the health disparities that Black and Hispanic patients with myeloma have experienced following their diagnoses. He has also studied and written about the current challenges to having Black patients with myeloma participate in cancer clinical trials, noting that racial disparities persist in the care of and outcomes for minority patients, and he has proposed solutions for the issue.

In 2021, Dr. Al Hadidi chaired and moderated the American Society of Hematology Diversity and Equity Poster Walk and held several interviews discussing racial disparities in myeloma treatment, including that Black patients are underrepresented in CAR-T trials.

Here are some of papers that Al Hadidi co-authored and media coverage on the studies:
