Alex F. Herrera, MD, on Previously Untreated DLBCL: Circulation Tumor DNA and Risk Profiling
2022 ASH Annual Meeting and Exposition
Alex F. Herrera, MD, of the City of Hope National Medical Center, discusses results from the POLARIX study, which showed that circulating tumor DNA (ctDNA) analysis has prognostic value for patients with previously untreated diffuse large B-cell lymphoma. Patients who did not achieve 2.5 or greater log-fold change and/or did not have ctDNA clearance following one cycle of polatuzumab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone had inferior outcomes than those who did. Early changes in ctDNA levels may be of use in risk-adapted trial designs to identify patients in need of alternative treatment. (Abstract 542).

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).

Anand P. Jillella, MD, of Georgia Cancer Center at Augusta University, discusses results from the ECOG-ACRIN EA9131 Trial, which showed that using a simplified treatment algorithm and management recommendations made by a group of specialists, resulted in a dramatic improvement in 1-year survival of patients with acute promyelocytic leukemia (Abstract 421).

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).

Eileen M. Boyle, MD, PhD, of the Perlmutter Cancer Center, NYU Langone Health, discusses Fc-mediated antibody effector function, inflammation resolution, and oligoclonality and their role in predicting sustained measurable residual disease negativity in patients with newly diagnosed multiple myeloma who were treated with immunotherapy regimens. For the first time, an analysis of T-cell receptors shows that oligoclonal profiles seen on treatment may influence the fitness of the immune response (Abstract 100).

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).
