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).

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).

Guillermo Garcia-Manero, MD, of The University of Texas MD Anderson Cancer Center, reviews data from three abstracts in myelodysplastic syndromes (MDS) presented at this year’s meeting: outcomes from the phase III VERONA trial of venetoclax with azacitidine vs placebo with azacitidine in patients with treatment-naive intermediate- and higher-risk MDS (Abstract 235); safety and efficacy results from a phase Ib trial of a dual IRAK1/4 inhibitor in patients with relapsed/refractory lower-risk MDS (Abstract 489); and results from the phase II ASTX030-01 trial, showing pharmacokinetic, efficacy, and safety data of oral ASTX030 in patients with MDS (Abstract 491).

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).

Dory Abelman, PhD(c), HBHSc, of the University of Toronto, discusses findings that support the feasibility of ultradeep cell-free DNA whole-genome sequencing for comprehensive genomic profiling in patients with multiple myeloma, which may be a less invasive alternative to bone marrow biopsy (Abstract 495).

Ibrahim Aldoss, MD, of City of Hope, presents findings from a small, single-center study of patients aged 55 years and older with B-cell acute lymphoblastic leukemia (ALL) in first complete remission who were treated with CD19-directed CAR T-cell therapy. Researchers found the therapy was safe, resulted in low-grade adverse events, and led to preliminary durable measurable residual disease response (Abstract 443).
