Valeria Santini, MD, on Imetelstat for Lower-Risk MDS: Long-Term Outcomes From the IMerge Trial
ASH 2025
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).

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).

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).

Amer Zeidan, MBBS, of Yale School of Medicine, discusses findings from an analysis of the IMerge trial, which explored the possible association between imetelstat-related cytopenias and hemoglobin increase—a measure linked to red blood cell transfusion independence achievement—in patients with lower-risk myelodysplastic syndromes (MDS) (Abstract 490).

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).

Benjamin Diamond, MD, of the University of Miami, describes findings from the single-center phase II REKINDLE trial, which looked at the combination regimen of iberdomide, carfilzomib, daratumumab, and dexamethasone in patients with early relapsed/refractory multiple myeloma (Abstract 251).
