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).

Karthik Ramasamy, MBBS, FRCP, FRCPath, PhD, of the University of Oxford, discusses initial results of the phase II/III UK-based RADAR trial. The study evaluated isatuximab, bortezomib, lenalidomide, dexamethasone, and cyclophosphamide induction, followed by single autologous stem cell transplant, consolidation with isatuximab plus bortezomib, lenalidomide, and dexamethasone, and isatuximab plus lenalidomide maintenance, in patients with double-hit multiple myeloma (Abstract 98).

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).

Jack Khouri, MD, of Cleveland Clinic, describes the findings of a phase II trial which investigated the safety and efficacy of burixafor (GPC-100), a potent and selective small -molecule antagonist of CXCR4, and propranolol with granulocyte colony-stimulating factor (G-CSF) for the mobilization of hematopoietic progenitor cells (HPC) in patients with multiple myeloma. Researchers aimed to boost the bone marrow HPC niche and optimize mobilization in patients with multiple myeloma eligible for autologous hematopoietic cell transplant (Abstract 1050).

Anand Patel, MD, of the University of Chicago, discusses results from a phase II trial that showed tyrosine kinase inhibitor plus inotuzumab ozogamicin–based therapy resulted in major molecular response in patients newly diagnosed with Philadelphia chromosome (Ph)-positive acute lymphoblastic leukemia (ALL) (Abstract 441).

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).
