Exicure Announces Phase 2 Trial Results for Multiple Myeloma Treatment
Exicure announced results from its completed Phase 2 trial evaluating burixafor in combination with propranolol and granulocyte colony-stimulating factor for the mobilization of hematopoietic progenitor cells in patients with multiple myeloma undergoing autologous hematopoietic cell transplantation. The data, which showed that approximately 90% of study participants achieved the primary endpoint, were presented in an oral session at the 67th American Society of Hematology annual meeting in Orlando, Florida. Burixafor is an investigational small molecule that blocks CXCL12 binding to CXCR4 receptors on HPCs, rapidly mobilizing these cells from the bone marrow into the peripheral blood. In preclinical studies, propranolol enhanced burixafor-induced mobilization by inhibiting the ss2-adrenergic receptor. In the open-label, multicenter Phase 2 trial, 17 of 19 participants achieved the primary endpoint. Two required another session to achieve 2x106 CD34+ cells/kg. Among participants who proceeded to transplant, the median time to neutrophil engraftment was 13 days, and the median time to platelet engraftment was 17.5 days. Burixafor has a differentiated and rapid mobilization kinetics, with peak peripheral levels of CD34+ cells observed within one hour of administration. This distinguishes it from other CXCR4 inhibitors and allows for same day burixafor administration and apheresis. Notably, 16 of 19 participants had prior exposure to daratumumab, a therapy associated with reduced mobilization, yet 14 of those 16 participants achieved the primary endpoint, including 12 of 14 participants who had received both daratumumab and lenalidomide. Longer intervals between the last dose of daratumumab and leukapheresis were associated with higher CD34+ cell yields. Burixafor administered in combination with propranolol and G-CSF was well tolerated and demonstrated an excellent safety profile. There were no burixafor-related adverse events higher than Grade 2.

About the author

- Research Presentation: Exicure will showcase data from its open-label, multicenter Phase 2 trial at the ASTCT meeting from February 4-7, 2026, highlighting the application of burixafor in autologous hematopoietic cell transplantation for multiple myeloma patients, achieving an impressive 89.7% success rate for the primary endpoint, demonstrating both efficacy and safety of the therapy.
- Therapeutic Innovation: The study indicates that the combination of burixafor with propranolol and G-CSF effectively mobilizes hematopoietic progenitor cells, addressing mobilization challenges faced by multiple myeloma patients, particularly in the context of lenalidomide and daratumumab treatment.
- Clinical Application Potential: By blocking CXCR4, burixafor is expected to enhance stem cell mobilization for conditions like multiple myeloma and sickle cell disease, providing a reliable collection strategy for patients who may encounter barriers to successful stem cell collection.
- Future Research Plans: Exicure is also planning a chemosensitization trial in acute myeloid leukemia, leveraging burixafor's ability to mobilize malignant cells from protective bone marrow niches to improve chemotherapy effectiveness, further expanding its therapeutic potential in hematologic diseases.
