Roni Shouval, MD, PhD, on TP53-Mutant Large B-Cell Lymphoma and CAR T-Cell Therapy
2021 ASH Annual Meeting & Exposition
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).

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).

Nikhil C. Munshi, MD, PhD, of Dana-Farber Cancer Institute, discusses the findings from a large nationwide Veterans Affairs study, which showed that, for patients with multiple myeloma, the effectiveness of the COVID-19 vaccine is reduced, likely due to patients’ immunosuppression. Dr. Munshi describes what next steps should be taken (Abstract 400).

Tarek H. Mouhieddine, MD, of The Mount Sinai Hospital and The Icahn School of Medicine at Mount Sinai, discusses data that suggest patients with heavily pretreated, predominantly triple-class refractory multiple myeloma who relapse after treatment with bispecific antibodies may still have good outcomes when sequentially treating with other immunologic treatments (Abstract 821).

Manali Kamdar, MD, of the University of Colorado Cancer Center, discusses phase III results from the TRANSFORM study, which suggest that lisocabtagene maraleucel, a CD19-directed CAR T-cell therapy, improved outcomes with a favorable safety profile and may be a potential new standard of care for second-line treatment of patients with relapsed or refractory large B-cell lymphoma (Abstract 91).

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).
