Amer Zeidan, MBBS, on TP53-Mutated Higher-Risk MDS: Bexmarilimab Plus Azacitidine
ASH 2025
Amer Zeidan, MBBS, of Yale School of Medicine, shares results from the phase I/II BEXMAB study, which examined the safety, tolerability and preliminary efficacy of bexmarilimab—a novel macrophage checkpoint inhibitor targeting Clever-1—in combination with the standard of care, azacitidine, in patients with higher-risk myelodysplastic syndromes (MDS), including those with TP53-mutated disease. (Abstract 236).

Alexander Lesokhin, MD, of Memorial Sloan Kettering Cancer Center, discusses results of a retrospective analysis from the phase II MagnetisMM-3 trial. A post hoc analysis was conducted of the subgroup of patients enrolled in the study who had a prolonged treatment interruption or who permanently discontinued elranatamab and maintained their responses for 6 months or longer (Abstract 2269).

Jennifer Woyach, MD, of The Ohio State University Comprehensive Cancer Center, reviews phase I data on rocbrutinib, a new selective next-generation inhibitor of Bruton’s tyrosine kinase (BTK), in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) and prior exposure to BTK and/or BCL-2 inhibitors (Abstract 87).

Brian Ball, MD, of City of Hope, presents updated results from the phase I/II BEXMAB study. They showed that the doublet had encouraging activity in patients with TP53-mutant, higher-risk MDS; translational data support the combination regimen’s potential for altering immune dysregulation in this subtype (Abstract 236).

Aaron Gerds, MD, of Cleveland Clinic, reviews results of an evaluation of Synapsis AI, a medically trained, large language model–based end-to-end system, focusing on its accuracy and efficiency in identifying eligible patients for an active phase III polycythemia vera clinical trial (Abstract 4340).

The telomerase inhibitor imetelstat was approved for the treatment of certain patients with lower-risk myelodysplastic syndromes (MDS) based on the results of the phase III IMerge trial. Valeria Santini, MD, of the University of Florence, provides updates on secondary endpoints, including overall and progression-free survival; progression to acute myeloid leukemia; safety; and long-term outcomes by subgroups of interest in IMerge, as well as ad hoc outcomes, including overall survival by response (Abstract 2074).
