A New Era in GVHD Prophylaxis: A Conversation With Dr. Samer Al-Homsi

In this episode of "ASTCT Talks," Dr. Shernan Holtan sits down with Dr. Samer Al-Homsi, as he shares his insights on the future of graft versus host disease (GVHD) prophylaxis, particularly in haploidentical transplantation. Dr. Al-Homsi delves into the innovative CAST regimen, which combines post-transplant cyclophosphamide, abatacept and short-duration tacrolimus. Learn about the challenges, breakthroughs and promising results that could revolutionize how we approach GVHD prevention and treatment, making a future without GVHD a reality. Listen in as we explore the potential for reducing transplant toxicities and the impact on patient care. About Dr. Samer Al-Homsi A. Samer Al-Homsi, MD, MBA, is the System Chief of Blood and Marrow Transplant and Cellular Therapy at Northwell Health Cancer Institute and serves as Director of Faculty and Academic Affairs in Medical Oncology. He is a Professor of Medicine at the Zucker School of Medicine and of Cancer Research at Feinstein Institutes of Medical Research. Previously, he was the Executive Director of Blood and Marrow Transplantation at NYU Grossman School of Medicine. Dr. Al-Homsi graduated from Damascus Medical School and trained in Hematology and Medical Oncology in France. He completed his residency at Advocate Health Care and fellowship at the University of Massachusetts. He has led programs in Malignant Hematology and Blood and Marrow Transplantation at several institutions, including NYU Langone Health. His research focuses on preventing graft-versus-host disease (GvHD), developing innovative approaches such as the CyBor and CAST regimens, particularly in haploidentical transplants. Dr. Al-Homsi aims to address healthcare disparities due to donor shortages among minority groups. Dr. Al-Homsi is also the President of the American Arab Assembly of Cellular Therapy and Transplantation (AAACTT), promoting collaboration among its members. About Dr. Shernan Holtan Dr. Holtan is a clinical/translational investigator. Her work focuses on increasing resilience, both at the tissue level to prevent and treat GVHD, and at the whole person level, designing exercise programs to mitigate cancer therapy-associated aging. In GVHD, her early work focused on epidermal growth factor and pregnancy hormones to facilitate tissue repair in GVHD, which led to a successful phase II study for the treatment of high-risk acute GVHD and discovery of the GVHD biomarker amphiregulin. More recently, she has led and published two prospective clinical trials regarding the use of PTCy as GVHD prophylaxis, the results of which are changing practice around the globe. Dr. Holtan has also been a competitive powerlifter, setting a national record in 2019. She has leveraged her knowledge regarding strength training into translational studies and clinical trials that are helping to reverse some of the damage done by high-dose chemotherapy and radiation. Through her multidimensional accomplishments, Dr. Holtan has demonstrated a unique and powerful intersection of medical research and physical resilience, redefining standards of care in HCT, and innovatively combating the deleterious effects of cancer treatment.
