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).

Mark R. Litzow, MD, of the Mayo Clinic, discusses phase III results from the ECOG-ACRIN E1910 Trial, which show that adding blinatumomab to consolidation chemotherapy resulted in a significantly better overall survival in adult patients aged 30 to 70 years with newly diagnosed B-lineage acute lymphocytic leukemia (ALL) who were measurable residual disease–negative after receiving intensification chemotherapy. The authors believe this may represent a new standard of care for this population (Abstract LBA-1).

Paolo F. Caimi, MD, of the Taussig Cancer Institute, Cleveland Clinic, discusses new findings showing that patients with diffuse large B-cell lymphoma (DLBCL) who achieve a complete response after salvage therapy with rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) can achieve long-term disease control, regardless of the time to relapse from initial therapy, particularly if they proceed to autologous stem cell transplant (ASCT). These results suggest that second-line chemotherapy followed by ASCT and/or CAR T-cell therapy for chemosensitive and chemorefractory patients may maximize patient outcomes, regardless of time to relapse (Abstract 156).

Paul G. Richardson, MD, of the Dana-Farber Cancer Institute, discusses preliminary results from the dose-expansion phase of the CC-92480-MM-001 Trial, which showed promising efficacy in patients with relapsed and refractory multiple myeloma, including those with prior BCMA-targeted therapies. Patients in these two groups had an overall response rate of 40% and 50%, respectively. The results support the development of mezigdomide, currently being evaluated in combination with standard therapies in multiple myeloma as part of a large, ongoing phase I/II trial (NCT03989414) and planned phase III studies (Abstract 568).

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).

Elias Jabbour, MD, of The University of Texas MD Anderson Cancer Center, discusses an analysis confirming that olverembatinib is a potentially viable treatment option for patients with chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (ALL), including those with CML whose disease did not respond to ponatinib or asciminib, or who had a T315I mutation (Abstract 82).
