Exicure Announces Publication in Annals of Hematology Highlighting Rapid Stem Cell Mobilization with Burixafor in Patients with Multiple Myeloma and Lymphoma Undergoing Transplant

Phase 2 data demonstrate differentiated CXCR4 inhibition kinetics enabling same-day cell collection, with rapid lymphocyte mobilization supporting potential therapeutic applications beyond transplant

Excerpt from the Press Release:

REDWOOD CITY, Calif., Feb. 05, 2026 (GLOBE NEWSWIRE) — Exicure, Inc. (Nasdaq: XCUR), a clinical-stage biotechnology company developing therapeutics for hematologic diseases, today announced the publication of results from a prior Phase 2 clinical study evaluating burixafor (GPC-100/TG-0054), a highly selective CXCR4 inhibitor, in the journal Annals of Hematology.

The manuscript, titled “Burixafor, a CXCR4 Inhibitor with a Differentiated Kinetics Profile: Results of a Phase 2 Study for Rapid Cell Mobilization in Multiple Myeloma and Lymphoma Patients Undergoing Transplant,” reports results from a 12-participant, multi-center, open-label Phase 2 study (NCT02104427) evaluating burixafor in combination with granulocyte colony-stimulating factor (G-CSF) in patients with multiple myeloma (MM), non-Hodgkin’s lymphoma (NHL), and Hodgkin disease (HD) undergoing autologous stem cell transplantation (ASCT).

In the study, 11 of 12 participants (92%) met the primary endpoint of collecting ≥5.0 × 10⁶ CD34+ cells/kg within two leukapheresis sessions, with six participants achieving the target in a single session. Median time to neutrophil and platelet engraftment was 12 and 22 days, respectively. Burixafor was generally well tolerated, with only two treatment-related adverse events reported, both low grade.
