Awardees were recognized on Sunday, June 5th during the 2022 American Transplant Congress.

Advancing Equity in Organ Transplantation Award

Lawrence Y.C. Agodoa, MD
National Institutes of Health

The Advancing Equity in Organ Transplantation Award was established in 2021 to recognize individuals whose work has made a significant impact on increasing equity and reducing racial disparities in transplantation.  The second annual Advancing Equity in Organ Transplantation Award was awarded in 2022 to Dr. Lawrence Agodoa, Director of the Office of Minority Health Research Coordination at the National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health.

Dr. Agodoa has had a long and distinguished academic career as an NIH scientist focused on reducing racial disparities in end-stage renal disease. He has published more than 300 peer-reviewed scientific papers that have been cited over fifty thousand times. Several of his papers describing racial inequities in kidney disease, dialysis access and outcomes, and kidney transplantation are required reading for trainees and faculty alike who want to understand disparities in the field. He is most well-known for being the program scientist and coordinator of the African American Study of Kidney Disease and Hypertension Cohort, a clinical trial of more than one thousand African Americans with kidney disease and high blood pressure which identified, for the first time, a specific treatment (ACE inhibitor) that slowed kidney disease caused by high blood pressure. This landmark study forever changed the medical management of such patients and their eventual trajectory to kidney transplantation.

For many years, Dr. Agodoa has served as the Director of the NIDDK’s Office of Minority Health Research Coordination, which was established to address diseases that disproportionately impact the health of minority populations. In this role, he oversees the Native American Research Centers for Health, the Research Enhancement Awards, and the Minority Biomedical Research Support Program. He is also responsible for fostering the recruitment and training of minority biomedical investigators. Finally, he serves as a member on the NIH Health Disparities Strategic Plan Working Group, Chair of the HHS Healthy People Initiative CKD Workgroup, and the Nephrology Chair on the National Medical Association’s Internal Medicine Steering Committee.

More specific to transplantation, nearly 30 years ago Dr. Agodoa designed and lobbied the NIDDK and NMHHD directors for the creation of a federal grants program to fund studies to evaluate strategies that might reduce disparities in organ donation and transplantation. With this pioneering idea, he was single-handedly responsible for the development and implementation of what became known as the Minority Organ Tissue Donation Program, which he continues to oversee to this day. Its aims are to increase organ donation among members of racial and ethnic minority communities and to reduce disparities in transplantation access. The program has contributed substantially to the development of academic careers and to the scientific mentorship of faculty in the field of transplantation, including three members of the AST’s IDEAL Task Force. Five R01 grants are funded each program cycle to study disparity-reducing strategies in organ donation and transplantation that are now used by transplant programs and OPOs today. He is singularly responsible for ensuring that this type of research has sufficient funding set aside within the NIDDK coffers, thus allowing the field – and new scientific discoveries – to move forward.

Dr. Agodoa’s commitment to eradicating disparities in ESRD and kidney transplantation is unparalleled.

Clinical Science Career Development Award

Marlena Habal, MD
Columbia University of Physicians and Surgeons

The 2022 AST Clinical Science Career Development Award went to Dr. Marlena Habal of Columbia University College of Physicians and Surgeons.

Dr. Habal is a practicing transplant cardiologist committed to developing innovative translational and clinical research programs aimed at improving transplant outcomes for patients with end stage heart failure. During her first year as an Assistant Professor, she completed a study using belatacept in combination with a proteasome inhibitor and showed that desensitization was associated with a decrease in germinal center responses and a shift in NK cells to a more activated phenotype. The study provided insights into mechanism of action and was published in the AJT in 2020. Dr. Habal leveraged these results to obtain an investigator-initiated research grant from industry to test Belatacept in heart transplantation and an R34 from the NIH to support the planning of a multicenter clinical trial to assess the safety and efficacy of belatacept with tacrolimus tapering in heart transplant recipients. She also received Columbia University’s Nelson Faculty Development Award and the Mendez National Institute of Transplantation Foundation grant to create assays aimed at developing mechanistic understanding and biomarkers to predict and monitor for a successful desensitization response and to identify new therapeutic targets to further improve desensitization.

In addition to launching her independent clinical and research career, Dr. Habal has been actively engaged with AST. She has served as the co-editor of “This week in Transplant-Transplant News” since 2019 and as a breakout session leader at the AST Fellows Conference in 2020 and 2021.

Dr. Habal has already made several remarkable findings and is poised to build on her successful clinical studies to address critical issues in heart transplantation. 

Distinguished Early Career Award

Nicole Valenzuela, PhD, D(ABHI)
University of California, Los Angeles

The 2022 Distinguished Early Career Award went to Dr. Nicole Valenzuela of the University of California, Los Angeles. Dr. Valenzuela is an Assistant Director at the UCLA Immunogenetics Center and an Assistant Professor in the Department of Pathology and Laboratory Medicine.
