Jack Khouri, MD, on Multiple Myeloma: Burixafor and Propranolol With G-CSF Before Transplant
ASH 2025
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).

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).

Nitin Jain, MD, of The University of Texas MD Anderson Cancer Center, reviews findings from a phase II trial of pirtobrutinib, venetoclax, and obinutuzumab for patients with Richter transformation (Abstract 89).

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).

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).

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).
