– Pivotal Phase 3 clinical trial of lead candidate mavorixafor in WHIM syndrome ongoing with
top-line results expected in the second half of 2021 –

– Initial Phase 1b results in ongoing Waldenström’s macroglobulinemia (WM) and Severe Congenital Neutropenia (SCN) trials expected in the second half of 2020 –

Cambridge, MA — March 12, 2020 — X4 Pharmaceuticals, Inc. (Nasdaq: XFOR), a leader in the discovery and development of novel therapies targeting diseases resulting from dysfunction of the CXCR4 pathway, today provided a corporate update and reported financial results for the fourth quarter and full year ended December 31, 2019.

“2019 was a remarkable year for X4, with significant achievements across the entire organization,” said Paula Ragan, Ph.D., President and Chief Executive Officer of the Company. “We made important progress advancing our lead therapeutic candidate mavorixafor into pivotal Phase 3 development for patients with WHIM syndrome, while also initiating two proof-of-concept clinical trials in SCN and Waldenström’s, and strengthening both our leadership team and Board of Directors. We’re now well positioned for the years ahead as we focus on near-term clinical trial execution and prepare for key value creation events in our quest to bring new transformative therapies to patients with rare diseases.”

Key 2019 Program Achievements and Upcoming Milestones

Initiated Pivotal Phase 3 Clinical Trial of Mavorixafor for the Treatment of WHIM Syndrome – June 2019: The 4WHIM trial is a pivotal Phase 3 global clinical trial of mavorixafor for the treatment of WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome, a rare, inherited, primary immunodeficiency disease.
Top-line data from the trial are expected in the second half of 2021.
Company to hold Analyst Day, which will also be webcast, on April 7, 2020 to discuss strategic focus on WHIM.
Phase 2 open-label extension study data update expected in mid-2020.
Received Orphan Drug Designation from the European Commission for Mavorixafor for the Treatment of WHIM Syndrome – July 2019
Received Scientific Advice from the European Medicines Agency to align the Phase 3 registration trial globally.
Announced Positive Data from Phase 2a Trial of Mavorixafor in Clear Cell Renal Cell Carcinoma (ccRCC) Patients – September 2019: Data presented at the European Society for Medical Oncology (ESMO) demonstrated that mavorixafor, in combination with axitinib yielded clinically meaningful improvements in median progression-free survival (mPFS) in a heavily pretreated advanced ccRCC patient population, and was generally well tolerated.



Initiated Phase 1b Clinical Trial of Mavorixafor in Patients with Severe Congenital Neutropenia (SCN) – November 2019: The Phase 1b trial is a 14-day, proof-of-concept trial designed to assess the safety and tolerability of daily, oral mavorixafor in up to 45 patients with SCN and other selected congenital neutropenia disorders. The trial will evaluate the neutrophil response and genetic profiles in this patient population as an independent agent or in combination with granulocyte-colony stimulating factor (G-CSF).
Initial data from this trial are expected in the second half of 2020.
Received Breakthrough Therapy Designation from U.S. FDA for Mavorixafor for the Treatment of WHIM Syndrome – November 2019: Highlighting the severity of the disease and the relevance of mavorixafor’s Phase 2 clinical trial data to support the drug’s role as a potential disease-modifying therapeutic option to this underserved patient population, Breakthrough Therapy Designation could expedite the development and regulatory review of mavorixafor.
Initiated Phase 1b Clinical Trial of Mavorixafor in Combination with Ibrutinib in Patients with Waldenström’s Macroglobulinemia – December 2019: The Phase 1b multi-center, open-label, dose-escalation clinical trial is designed to assess the safety and tolerability of mavorixafor in combination with ibrutinib as well as to obtain certain efficacy signals in patients with Waldenström’s, a rare form of non-Hodgkin’s lymphoma, who have acquired a “gain of function” mutation in CXCR4 in addition to the MYD88 mutation, which is a hallmark of Waldenström’s.
Initial data from this trial are expected in the second half of 2020.
Granted New Composition of Matter Patent by U.S. PTO for Mavorixafor – February 2020: Patent expected to provide exclusivity through 2038.

About Mavorixafor
Mavorixafor is an investigational, oral, targeted therapy that antagonizes the chemokine receptor CXCR4 via allosteric inhibition. The CXCR4 receptor plays a key role in enabling the trafficking of immune cells and effective immunosurveillance. Over-stimulation of CXCR4 results in various immune-system deficiencies. X4 Pharmaceuticals is currently investigating mavorixafor as a once-daily treatment in a global Phase 3 pivotal trial in patients with WHIM syndrome, a rare, inherited, primary immunodeficiency disease caused by genetic mutations in the CXCR4 receptor gene. The FDA has granted Breakthrough Therapy Designation to mavorixafor for the treatment of WHIM syndrome. Mavorixafor is being developed in two proof-of-concept Phase 1b clinical trials – as monotherapy in patients with Severe Congenital Neutropenia (SCN), a group of rare blood disorders characterized by abnormally low levels of white blood cells, and in combination with ibrutinib in patients with Waldenström’s macroglobulinemia, a form of non-Hodgkin’s lymphoma, who have acquired mutations in the CXCR4 receptor.

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 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, oral, small molecule antagonist of chemokine receptor CXCR4. 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 global Phase 3 clinical trial in patients with WHIM syndrome, and in two Phase 1b clinical trials – as monotherapy in patients with Severe Congenital Neutropenia (SCN) and in combination with ibrutinib in patients with Waldenström’s macroglobulinemia. X4 is continuing to leverage its insights into CXCR4 biology at its corporate headquarters in Cambridge, Massachusetts and at its research facility in Vienna, Austria, and is discovering and developing additional product candidates.
