About X4 Pharmaceuticals Inc (XFOR)
X4 Pharmaceuticals Inc is a clinical-stage biopharmaceutical company dedicated to developing innovative oral therapeutics that target the immune system for the treatment of rare diseases. Leveraging deep expertise in immunology and CXCR4 receptor biology, the company focuses on addressing conditions characterized by immune dysfunction, including WHIM syndrome and various chronic neutropenic disorders. Its lead clinical candidate, mavorixafor, is a selective, small-molecule CXCR4 antagonist designed to enhance the mobilization of functional white blood cells by inhibiting the interaction between the chemokine CXCL12 and its receptor CXCR4.
