Leslie S. Kean, MD, PhD, on Bone Marrow Transplantation: Using Abatacept to Prevent Graft-vs-Host Disease
2021 ASH Annual Meeting & Exposition
Leslie S. Kean, MD, PhD, of Dana-Farber/Boston Children's Cancer and Blood Disorders Center, discusses findings from her analysis of the International Blood and Marrow Transplant Research Database, which led to the recent FDA approval of abatacept for the prevention of acute graft-vs-host disease (GVHD) in adult and pediatric patients. The data suggest improved overall survival with the immunosuppressant abatacept in combination with a calcineurin inhibitor and methotrexate following 7/8 HLA–matched unrelated allogeneic hematopoietic stem cell transplantation (Abstract 3912).

Carsten Utoft Niemann, MD, PhD, of Copenhagen University Hospital, discusses a primary analysis of the phase II Vision HO141 trial, which showed the feasibility of stopping and restarting ibrutinib and venetoclax in patients with relapsed or refractory chronic lymphocytic leukemia who have undetectable measurable residual disease. A favorable benefit-risk profile was demonstrated, with no new safety signals (Abstract 69).

Andrew Matthews, MD, of the Abramson Cancer Center, University of Pennsylvania, discusses findings from a retrospective study at an academic institution, which showed there was no statistically significant difference in overall survival between induction with CPX-351 and venetoclax/azacitidine for adults with acute myeloid leukemia. Prospective studies to confirm similar effectiveness with careful attention to side effects, quality of life, and impact on transplant outcomes may help clinicians decide between these therapies (Abstract 795).

Michael R. Bishop, MD, of the University of Chicago, discusses insights from findings of the phase III BELINDA study, which may inform the design of future CAR T-cell trials, as well as the use of second-line tisagenlecleucel therapy in patients with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma (Abstract LBA-6).

Alba Rodriguez-Meira, DPhil, of the University of Oxford, discusses a comprehensive analysis of the genetic, cellular, and molecular landscape of TP53-mediated transformation, providing insights into the evolution of chronic hematologic malignancies toward an aggressive acute leukemia. Because TP53 is the most commonly mutated gene in human cancer, these findings may well be of broad relevance (Abstract 3).

Roni Shouval, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses his findings, which show, for the first time, that TP53 alterations are a valuable prognostic and potentially predictive marker in patients with large B-cell lymphoma who receive CD19–CAR T-cell therapy. Gene-expression profiling suggests that TP53 alterations result in an immunosuppressive tumor microenvironment and impaired apoptosis signaling, which could lead to decreased CAR T-cell therapy efficacy (Abstract 710).
