BOSTON, Sept. 08, 2021 (GLOBE NEWSWIRE) -- X4 Pharmaceuticals, Inc. (Nasdaq: XFOR), a leader in the discovery and development of novel therapies targeting diseases of the immune system resulting from dysfunction of the CXCR4 pathway, today announced the promotion of Mary DiBiase, Ph.D. to the newly created position of Chief Operating Officer. Dr. DiBiase had served as Senior Vice President and previously Vice President of Technical Operations and Quality in addition to Vice President of Program and Alliance Management since joining the company in 2017. In this new role, Dr. DiBiase’s responsibilities expand beyond chemistry, manufacturing and controls (CMC) and quality to include oversight of program and alliance management and information technology (IT) management.

We look forward to further leveraging her proven leadership skills and her strategic and operational capabilities to enable the growth of X4. Mary’s expertise will continue to be invaluable to me and the company as we advance our additional clinical and pre-clinical pipeline and prepare to evolve into a larger, potentially commercial-stage entity.”

About X4 Pharmaceuticals
X4 Pharmaceuticals is a late-stage clinical biopharmaceutical company and a leader in the discovery and development of novel therapies for the treatment of diseases



of the immune system resulting from dysfunction of the CXCR4 pathway, with a focus on rare diseases and those with limited treatment options. The company’s lead candidate, mavorixafor, is a first-in-class, small molecule antagonist of chemokine receptor CXCR4 being developed as a once-daily oral therapy. X4 believes that inhibition of the CXCR4 receptor creates the potential for mavorixafor to provide therapeutic benefit across a wide variety of diseases, including primary immunodeficiencies and certain types of cancer. The efficacy and safety of mavorixafor, dosed once daily, is currently being evaluated in a number of clinical trials, including a global Phase 3 clinical trial in patients with WHIM syndrome, and in two Phase 1b clinical trials – in combination with ibrutinib in patients with Waldenström’s macroglobulinemia, and as monotherapy in patients with Severe Congenital Neutropenia and other chronic neutropenia disorders. X4 is continuing to leverage its insights into CXCR4 biology at its corporate headquarters in Boston, Massachusetts and at its research facility in Vienna, Austria, and is discovering and developing additional product candidates.
