The assistant professor of neurology at University of Washington, Seattle Children's discussed efforts to address a gap in knowledge in the long-term effects of CAR-T, if any, on children’s neurological development.
“We really currently have no evidence that CAR T-cells are harmful for the brain in the long term. There may be more subtle things that happen—we really have not done the work yet. But my hope is that in the end, we will find that CAR T-cells are more gentle for the brain and its development than our standard therapies that we're currently using.”
One of the most well-known common adverse events associated with chimeric antigen receptor T-cell (CAR-T) therapies is immune effector cell-associated neurotoxicity syndrome (ICANS). Although, ICANS is an acute adverse event typically manifesting shortly after administration of the treatment and ideally subsiding soon after its appearance. Furthermore, despite the fact that pediatric patients have been receiving CAR-T therapies for over 10 years now, CAR-T is still a relatively new therapeutic modality for children and adults alike. As such, data on long-term neurological effects on patients receiving CAR-T therapy, if any, are limited. In children especially, further study is needed to determine whether CAR-T may have a negative effect on neurological development.
Juliane Gust, MD, PhD, an assistant professor of neurology at University of Washington, Seattle Children's, is giving a talk entitled “Delayed Neurotoxicities Following CAR T-Cell Therapy” at the 2024 Tandem Meetings | Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR, held in San Antonio, Texas, February 21-24, 2024. In an interview with CGTLive® held shortly before her talk, Gust discussed the rationale behind her presentation and the key points that she will be speaking on. She noted that standard of care therapies for children with cancer such as chemotherapy, radiation, and transplant have well-documented long-term effects, but that long-terms effects for CAR-T in children are still largely unknown. Gust also highlighted a study that is currently underway via the National Cancer Institute’s CARnation Consortium that will seek to address this gap in knowledge through the use of remote follow-up assessments.
