X4 Pharmaceuticals, Inc., a late-stage clinical biopharmaceutical company, focuses on the research, development, and commercialization of novel therapeutics for the treatment of rare diseases. Its lead product candidate is mavorixafor, a small molecule inhibitor of the chemokine receptor C-X-C chemokine receptor type 4 (CXCR4), which is in Phase III clinical trial for the treatment of patients with warts, hypogammaglobulinemia, infections, and myelokathexis syndrome; and Phase Ib clinical trial to treat chronic neutropenia and Waldenström macroglobulinemia. The company is also developing X4P-002, a CXCR4 antagonist for the treatment of brain cancers; and X4P-003, a CXCR4 antagonist for the treatment of CXCR4 disorders and primary immunodeficiencies. It has a license agreement with Abbisko Therapeutics Co., Ltd. to develop, manufacture, and commercialize mavorixafor in combination with checkpoint inhibitors or other agents in oncology indications. The company was founded in 2010 and is headquartered in Boston, Massachusetts.

X4 Pharmaceuticals, Inc.

Leveraging our unparalleled expertise in diseases of the immune system and CXCR4 biology, we aim to bring innovative treatments to patients with chronic neutropenic disorders.

Our lead product candidate, mavorixafor, is a first-in-class CXCR4 inhibitor being developed as a once-daily, oral therapy for people with chronic neutropenic disorders. Mavorixafor has demonstrated the ability to mobilize immune cells from the bone marrow into the bloodstream, creating what we believe to be broad commercial potential in the estimated 50,000 (U.S.) diagnosed chronic neutropenia patients who currently have few to no treatment options.

We are currently evaluating the safety and efficacy of mavorixafor in a Phase 3 clinical trial for the treatment of people with WHIM syndrome; data from this Phase 3 study (4WHIM) are expected in the fourth quarter of 2022. We are also conducting a Phase 1b clinical trial of mavorixafor in people with idiopathic, cyclic, or congenital neutropenia. Based on positive data from the first part of this Phase 1b trial, we are currently amending and expanding the study to evaluate chronic use of daily oral mavorixafor with or without G-CSF in up to 50 participants with chronic neutropenic disorders. 

X4 is a public biopharmaceutical company (Nasdaq: XFOR) headquartered in Boston, Massachusetts, with a research center of excellence in Vienna, Austria.
