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, 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).

Mikkael Sekeres, MD, MS, Chief, Division of Hematology and Professor of Medicine at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, presents findings from a new study that connects exposure to the herbicide Agent Orange to earlier and more severe cases of myelodysplastic syndromes (MDS). Researchers concluded that exposure is associated with younger age at MDS diagnosis, ultimate MDS diagnosis, genetic complexity of MDS, increased risk of disease progression, and with Black race (Abstract 5626).

Jennifer Woyach, MD, of The Ohio State University Comprehensive Cancer Center, discusses results from the first head-to-head comparison of pirtobrutinib vs ibrutinib in treatment-naive patients and patients with covalent Bruton tyrosine kinase inhibitor–naive relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) (Abstract 683).

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).
