X4 Pharmaceuticals Reports First Quarter 2022 Financial Results and Provides Corporate Update


Top-line data from pivotal 4WHIM Phase 3 clinical trial in WHIM syndrome expected in 4Q22

Clinical and regulatory updates from ongoing chronic neutropenia Phase 1b study anticipated during 3Q 2022; Waldenström’s macroglobulinemia Phase 1b study now fully enrolled with results expected in second half of 2022

Conference call to be hosted today at 8:30 a.m. EDT

BOSTON, May 12, 2022 (GLOBE NEWSWIRE) -- X4 Pharmaceuticals, (Nasdaq: XFOR), a leader in the discovery and development of novel oral CXCR4-targeted small molecule therapeutics to benefit people with rare immune system disorders, today reported financial results for the first quarter ended March 31, 2022.

“As we quickly approach top-line results from our 4WHIM pivotal Phase 3 trial for WHIM syndrome by the end of this year, the X4 team continues to identify and expand the breadth of individuals diagnosed with this rare disease. Initiatives aimed at supporting diagnosis and driving disease awareness, such as our PATH4WARD program offering free genetic sequencing to patients, and publishing peer-reviewed research to help define novel pathogenic genetic variants, are adding to the population of those known to be affected by WHIM and chronic neutropenia,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “Specifically, to support those affected by chronic neutropenia, we are expanding the availability of genetic testing through PATH4WARD and evaluating patients with congenital, idiopathic, and cyclic chronic neutropenia in our ongoing Phase 1b study. We look forward to providing both clinical data and regulatory updates over the coming months on this important initiative.”        

Recent Highlights

  • Presented posters at the CIS 2022 Annual Meeting that detailed the PATH4WARD genetic testing program to aid in the diagnosis of WHIM syndrome and chronic neutropenia, and the characterization of a novel pathogenic CXCR4 variant (S341Y).
  • Presented preclinical data on mavorixafor’s ability to significantly enhance the tumor-cell killing activity of the leading commercial and clinical stage Bruton Tyrosine Kinase Inhibitors (BTKi) including ibrutinib, zanubrutinib, pirtobrutinib (LOXO-305) and nemtabrutinib (ARQ-531), at the 2022 AACR Annual Meeting.
  • Completed enrollment in the ongoing Phase 1b study of mavorixafor in combination with ibrutinib in patients with Waldenström’s Macroglobulinemia (WM) whose tumors express mutations in MYD88 and CXCR4. A total of 16 patients were enrolled and dose escalation to the 600 mg dose of mavorixafor has been completed. Results from this study are expected to be reported during the second half of 2022.

First Quarter 2022 Financial Results

  • Cash, Cash Equivalents & Restricted Cash: X4 had $67.7 million in cash, cash equivalents, and restricted cash as of March 31, 2022. The company expects that its cash and cash equivalents will fund company operations into the fourth quarter of 2022.

  • Selling, General and Administrative Expenses (SG&A) were $7.7 million for the first quarter of 2022 as compared to $5.8 million for the comparable period in 2021. SG&A expenses include $0.8 million and $0.7 million of certain non-cash expenses for the first quarter of 2022 and 2021, respectively.

About X4 Pharmaceuticals
X4 Pharmaceuticals is a late-stage clinical biopharmaceutical company leading the discovery and development of novel therapies for people with rare diseases of the immune system. The company’s lead candidate is mavorixafor, a first-in-class, small molecule antagonist of chemokine receptor CXCR4 that is being developed as a once-daily oral therapy. Due to mavorixafor’s ability to antagonize CXCR4 and improve the healthy maturation and trafficking of white blood cells, X4 believes that mavorixafor has the potential to provide therapeutic benefit across a wide variety of diseases, including primary immunodeficiencies (PIDs) and certain types of cancer. Mavorixafor has already demonstrated clinical potential in a Phase 2 trial in people with WHIM syndrome, a rare PID. Its efficacy and safety continue to be evaluated in a global Phase 3 clinical trial in WHIM (fully enrolled) and in two Phase 1b clinical trials – one, as monotherapy in people with chronic neutropenia, including Severe Congenital Neutropenia (SCN), and another in combination with ibrutinib in people with Waldenström’s macroglobulinemia (also fully enrolled). 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, to discover and develop additional product candidates.
