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.
Core Business Focus
X4 Pharmaceuticals is committed to advancing therapies that remedy the underlying biological mechanisms responsible for immune suppression and impaired cell trafficking. By targeting the CXCR4 pathway, its novel therapeutics are engineered to improve immune surveillance and provide a mechanism-based approach to rare immunodeficiencies. The company’s work is centered on:
- Developing an innovative oral therapy that modulates the immune system.
- Addressing critical unmet needs in patients with rare genetic immunodeficiency disorders.
- Utilizing precise pharmacological modulation to increase circulating neutrophils and lymphocytes.
Pipeline and Clinical Development
