X4 Pharmaceuticals (XFOR) presented positive Phase 2 trial data for mavorixafor in treating chronic neutropenia at the 30th EHA Congress. The 6-month study involving 23 participants demonstrated that oral, once-daily mavorixafor effectively increased absolute neutrophil count (ANC) both as monotherapy and in combination with G-CSF. Key findings showed that patients with severe chronic neutropenia achieved nearly 3-fold increases in mean ANC levels, and 89% of participants were able to reduce or discontinue injectable G-CSF while maintaining normal ANC levels. The drug was well-tolerated with no drug-related serious adverse events. A sub-study revealed that treated patients' functional neutrophil levels were comparable to healthy donors. The company is currently conducting a global Phase 3 pivotal trial, expected to complete enrollment in Q3/Q4 2025.

X4 Pharmaceuticals (XFOR) announced that the FDA has granted Fast Track designation to mavorixafor for treating chronic neutropenia (CN).

The company expects full trial enrollment in Q3/Q4 2025 with top-line data anticipated in late 2026. Currently, the only FDA-approved treatment for CN is injectable G-CSF, which has significant side effects including bone pain, splenomegaly, and increased leukemia risk. X4 believes oral mavorixafor could offer better disease control with reduced treatment burden for CN patients.
