Eunice S. Wang, MD, on AML: Gemtuzumab Ozogamicin Plus Standard Induction Chemotherapy Improves Outcomes
2022 ASH Annual Meeting and Exposition
Eunice S. Wang, MD, of Roswell Park Comprehensive Cancer Center, discusses the outcomes of patients newly diagnosed with acute myeloid leukemia (AML) who were treated with cytarabine plus daunorubicin plus gemtuzumab ozogamicin (GO). These patients experienced higher rates of measurable residual disease–negative complete remission and complete remission with incomplete count recovery, compared to those treated with cytarabine plus idarubicin daunorubicin alone. Although adding GO was not associated with improved overall survival, longer follow-up is warranted to determine an absolute survival advantage of this regimen (Abstract 58).

Jorge E. Cortes, MD, of Georgia Cancer Center at Augusta University, discusses new findings on vodobatinib, which was administered to patients with chronic-phase Philadelphia chromosome–positive chronic myeloid leukemia (CML) and appeared to be efficacious and safe in people who had received therapy with two or three prior tyrosine kinase inhibitors (TKIs). Vodobatinib remains a potential option for these highly refractory patients. A phase II study (NCT02629692) of vodobatinib is ongoing in CML patients whose disease has failed to respond to three or more TKIs, including ponatinib (Abstract 84).

Smita Bhatia, MD, MPH, of the Institute for Cancer Outcomes and Survivorship, University of Alabama at Birmingham, discusses study findings that showed key somatic mutations in the peripheral blood stem cell product increases the risk of developing therapy-related myeloid neoplasms (Abstract 119).

Tomohiro Aoki, MD, PhD, of the University of British Columbia and the Centre for Lymphoid Cancer at BC Cancer, discusses a novel prognostic model applicable to patients with relapsed or refractory classical Hodgkin lymphoma who were treated with autologous stem cell transplantation. The model has shown the interaction between the biomarker CXCR5 on HRS cells (Hodgkin and Reed/Sternberg cells, hallmarks of Hodgkin lymphoma) with specific follicular T helper cells and macrophages, a prominent crosstalk axis in relapsed disease. This insight opens new avenues to developing predictive biomarkers (Abstract 71).

Jiye Liu, PhD, of Dana-Farber Cancer Institute, discusses study findings that demonstrate KDM6A regulates CD38 and CD48 expression in multiple myeloma. Dr. Liu’s team validated combination treatment with an FDA-approved EZH2 inhibitor plus daratumumab, which can overcome daratumumab resistance in preclinical multiple myeloma models, providing the rationale for combination clinical trials to improve patient outcome (Abstract 148).

Jennifer R. Brown, MD, PhD, of Dana-Farber Cancer Institute, discusses phase III findings of the ALPINE study, which showed that zanubrutinib is more efficacious and better tolerated than ibrutinib as a treatment for patients with relapsed or refractory chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). In this first head-to-head comparison of the two BTK inhibitors, the superior progression-free survival of zanubrutinib was observed across all major subgroups, including high-risk patients (Abstract LBA-6).
