Tycel Phillips, MD, on Marginal Zone Lymphoma: Efficacy and Safety of Parsaclisib
2021 ASH Annual Meeting & Exposition
Tycel Phillips, MD, of the Rogel Cancer Center, University of Michigan, discusses phase II findings from the CITADEL-204 study of parsaclisib, a next-generation inhibitor of phosphatidylinositol 3-kinase. The agent, used as a monotherapy, appeared to benefit patients with relapsed or refractory marginal zone lymphoma who had a rapid and durable clinical response (Abstract 44).

Masayuki Umeda, MD, of St. Jude Children's Research Hospital, discusses his research which showed that UBTF-TD (upstream binding transcription factor-tandem duplications) define a unique subtype of acute myeloid leukemia that previously lacked a clear oncogenic driver. UBTF-TD is associated with FLT3-ITD and WT1 mutations, adolescent age, and poor outcomes. These alterations are critical for future risk-stratification for this patient cohort.

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).

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).

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).

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).
