2021 expected to be a year of key value-driving catalysts as company advances multiple clinical programs with lead candidate mavorixafor

Company anticipates completing full enrollment in WHIM Phase 3 trial in 2021 and presenting clinical data from the ongoing Phase 1b Waldenström’s trial throughout the year

Conference call today at 8:30 a.m. ET

BOSTON, March 04, 2021 (GLOBE NEWSWIRE) -- 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 reported financial results for the fourth quarter and full year ended December 31, 2020. The company also provided an update on its lead product candidate, mavorixafor, a novel small molecule currently being evaluated in a Phase 3 clinical trial (4WHIM) for patients with WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome and in two Phase 1b trials for patients with Waldenström’s macroglobulinemia (Waldenström’s) and Severe Congenital Neutropenia (SCN), respectively.

“As many companies did, we encountered a number of unexpected challenges in 2020, most notably the COVID-19 pandemic. However, I could not be prouder of our accomplishments, as we remained steadfast in our commitment to advance our lead candidate, mavorixafor, in a number of rare disease indications,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “We believe that we have much to look forward to this year, as we have overcome these obstacles, have made significant progress in advancing our clinical and research programs, and assembled an exceptional team to execute on our 2021 goals and beyond.

“On the clinical front, we continue to expect top-line data from our Phase 3 WHIM trial in 2022 and, as our Phase 1b Waldenström’s trial is progressing well, we continue to expect initial data from that study in the first half of 2021, with a more fulsome dataset expected towards the end of 2021. We also anticipate initial data from our SCN Phase 1b trial in 2021.”

Recent Highlights

  • Received Fast Track and Rare Pediatric Designations (RPD) from the FDA for Mavorixafor for the treatment of WHIM Syndrome: These FDA designations further recognize WHIM as a serious condition with a clear unmet need in both adult and pediatric populations.

    • Through the Fast Track program, X4 will be eligible for more frequent meetings with the FDA to discuss the drug’s development plan, protocols and clinical data that would support mavorixafor’s potential approval for WHIM.

    • Under the RPD program, a sponsor who receives an approval for a drug for a “rare pediatric disease” and a Fast Track designation may qualify for a voucher that can be redeemed to receive a priority review by the FDA for any subsequent marketing application for a different product. Such a voucher is transferable and may be sold.

    • Mavorixafor was previously granted Breakthrough Therapy Designation by the FDA, as well as Orphan Drug status by the FDA and the European Commission for the treatment of WHIM syndrome.

  • Strengthened Leadership Team: During the Fourth Quarter of 2020:

    • Diego Cadavid, M.D., joined as Chief Medical Officer, bringing more than 20 years of industry experience and having led multiple programs through all phases of clinical development, including small molecules and biologics for the treatment of rare and immunological diseases.

    • Art Taveras, Ph.D., joined as Chief Scientific Officer with more than 30 years of experience leading small molecule research and development programs focused on cancer, dysregulated immune disorders, neurodegeneration, and metabolic diseases.

    • Alison Lawton was appointed to the company’s Board of Directors, bringing more than 30 years of experience across a full spectrum of drug development and commercial roles and having previously served on X4’s corporate advisory board and as consulting Chief Operating Officer.

Fourth Quarter 2020 Financial Results

  • Cash, Cash Equivalents & Restricted Cash: X4 had $80.7 million in cash, cash equivalents and restricted cash as of December 31, 2020. X4 continues to expect that its cash and cash equivalents will fund company operations into 2022.

  • Research and Development Expenses were $12.3 million and $41.9 million for the fourth quarter and full year ended December 31, 2020, respectively, as compared to $7.1 million and $30.2 million for the comparable periods in 2019, respectively. R&D expenses include $0.6 million and $2.3 million of certain non-cash expenses for the fourth quarter and fully year ended December 31, 2020, respectively.

  • General and Administrative Expenses were $5.4 million and $20.9 million for the fourth quarter and full year ended December 31, 2020, respectively, as compared to $3.9 million and $17.6 million for the comparable periods in 2019, respectively. G&A expenses include $0.8 million and $3.1 million of certain non-cash expenses for the fourth quarter and full year ended December 31, 2020, respectively.

  • Net Loss: X4 reported net losses of $18.4 million and $62.1 million for the fourth quarter and full year ended December 31, 2020 as compared to net losses of $10.8 million and $52.8 million for the comparable periods in 2019, respectively.

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, 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 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. 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.
