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).

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).

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).

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).

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).

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).
