Ensuring Quality Outcomes in Hematologic Cancer Subgroups at EHA 2024

At the 2024 European Hematology Association (EHA) Congress, CancerNetwork^® spoke with a variety of experts in the hematologic oncology space about optimizing outcomes across different patient populations and subgroups based on updated research they presented at the meeting.

Manali Kamdar, MD, an associate professor of medicine-hematology and clinical director of Lymphoma Services at the University of Colorado Anschutz Medical Campus, in Colorado, spoke about data from the phase 1 TRANSCEND NHL 001 trial (NCT02631044) supporting the use of lisocabtagene maraleucel (liso-cel; Breyanzi) in earlier lines of therapy for patients with relapsed/refractory mantle cell lymphoma (MCL).¹

Specifically, Kamdar highlighted how research should continue to focus on the potential utility of liso-cel in MCL subgroups such as those with TP53 mutations or blastoid morphology. Additionally, she stated that liso-cel may need to be further tested in earlier lines of therapy for patients with diffuse large B-cell lymphoma, including those with double-hit lymphoma.

Michael R. Grunwald, MD, chief of the Leukemia Division and director of the Transplantation and Cellular Therapy Program at Atrium Health’s Levine Cancer Institute, in North Carolina, discussed findings from the Prospective Observational Study of Patients With Polycythemia Vera (PV) in US Clinical Practices Trial (REVEAL) exploring risk factors for disease progression in patients with polycythemia vera (PV).²

According to Grunwald, a history of thromboembolic events, elevated white blood cell counts, and higher variant allele frequencies may contribute to a patient’s likelihood of experiencing progression to myelofibrosis or acute myeloid leukemia (AML). Additionally, he highlighted ongoing research into the potential molecular factors that may prognosticate disease transformation in PV among a small cohort of patients enrolled on the REVEAL trial.³

Harry P. Erba, MD, PhD, a professor of medicine in the Division of Hematologic Malignancies and Cellular Therapy and the director of the Leukemia Program and Phase I Development in Hematologic Malignancies at Duke Cancer Institute, in North Carolina, discussed the clinical implications of data from the phase 3 QuANTUM-First study (NCT02668653).⁴

Specifically, findings demonstrated that continuation therapy with quizartinib (Vanflyta) elicited a more pronounced survival benefit vs placebo in patients with newly diagnosed FLT3-ITD–positive AML who did not undergo allogeneic hematopoietic stem cell transplant (allo-HSCT). However, Erba noted that survival outcomes were not significantly different in the quizartinib and placebo arms among patients who received allo-HSCT.
