X4 Pharmaceuticals

We are a commercial-stage clinical biopharmaceutical company driven to improve the lives of people with rare diseases of the immune system and few to no treatment options. We have successfully developed mavorixafor, receiving FDA approval for XOLREMDI™ (mavorixafor) in its first indication, and are currently executing our US launch. We are also advancing mavorixafor for additional rare disease patient populations, and expect to initiate a pivotal, global Phase 3 clinical trial in people with certain chronic neutropenic disorders. With a focus on CXCR4 and immune system biology, we continue to leverage our expertise both at our corporate headquarters in Boston, Massachusetts and at our research center of excellence in Vienna, Austria to further advance our patient-centric mission.
