X4 Pharmaceuticals Reports Fourth-Quarter and Full-Year 2023 Financial Results and Provides Corporate Update
Launch preparations underway in anticipation of possible U.S. approval of mavorixafor for WHIM syndrome; U.S. PDUFA target action date set for April 30, 2024
Additional Phase 2 clinical data and initiation of global Phase 3 clinical trial of mavorixafor for the treatment of certain chronic neutropenic disorders expected in 1H24
Conference call to be hosted today at 8:30 a.m. ET
BOSTON, March 21, 2024 (GLOBE NEWSWIRE) -- X4 Pharmaceuticals (Nasdaq: XFOR), a company driven to improve the lives of people with rare diseases of the immune system, today reported financial results for the fourth quarter and full year ended December 31, 2023, and highlighted key 2023 events and expected upcoming milestones.
“Following an incredibly productive 2023, we are expecting a transformative year in 2024,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “In 2023, we not only successfully submitted our New Drug Application for the potential first and only treatment for WHIM syndrome in the U.S., but also achieved clinical proof of concept for oral, once daily mavorixafor to address chronic neutropenia (CN), a second rare immunodeficiency. The excitement at X4 is palpable as we approach the potential launch of our first product and the expected initiation of the pivotal CN clinical program, both of which would bring us one step closer to fulfilling our mission to make progress for those diagnosed with rare diseases of the immune system and few or no treatment options.”
2023 Highlights and Expected Milestones on Mavorixafor Clinical & Commercial Development
In September 2023, X4 announced the submission of a New Drug Application (NDA) to the United States Food and Drug Administration (FDA) for the approval of once-daily, oral mavorixafor to treat individuals aged 12 and older with WHIM syndrome, a rare, combined primary immunodeficiency and chronic neutropenic disorder named for its four main manifestations: Warts, Hypogammaglobulinemia, Infections, and Myelokathexis.
In October 2023, the FDA accepted for filing and granted Priority Review of the mavorixafor NDA in WHIM syndrome, establishing a goal of six months review from the date of acceptance and assigning a Prescription Drug User Fee Act (PDUFA) target action date of April 30, 2024. Company discussions with the FDA to date have indicated that this action date remains on track.
The company continues to build out its rare disease field force and supportive commercial infrastructure as it prepares for the potential launch of mavorixafor for WHIM syndrome in the U.S., if approved.
For the WHIM syndrome indication, mavorixafor has been granted Breakthrough Therapy Designation, Fast Track Designation, and Rare Pediatric Disease (RPD) Designation in the U.S., and Orphan Drug Status in both the U.S. and European Union. Upon FDA approval of a product with RPD designation, the sponsor can receive a Priority Review Voucher that can be used to obtain priority review for a subsequent application or sold to another drug sponsor.
X4 continues to advance its ex-U.S. commercialization strategy for mavorixafor, evaluating multiple global and regional opportunities for partnerships or direct sales, including geographies where the company could leverage its U.S. approval, if received.
Following multiple presentations of positive Phase 1b and preliminary Phase 2 clinical trial data on mavorixafor in the treatment of certain chronic neutropenic disorders, the company continues to expect to announce additional Phase 2 results in 15+ trial participants and to initiate a global, pivotal, Phase 3 clinical trial in certain CN indications in the first half of 2024.
Fourth-Quarter and Full-Year 2023 Financial Results
Cash, Cash Equivalents, Restricted Cash, and Short-Term Marketable Securities: X4 had $115.2 million in cash, cash equivalents, restricted cash, and marketable securities as of December 31, 2023. X4 believes it has sufficient funds to support company operations into 2025 and notes that this projected runway does not include additional potential drawdowns from its debt facility nor the potential monetization of a Priority Review Voucher the company would expect to receive should mavorixafor be approved for WHIM syndrome in the U.S.
Research and Development (R&D) Expenses were $15.3 million and $72.0 million for the fourth quarter and full year ended December 31, 2023, respectively, as compared to $19.0 million and $61.1 million for the comparable periods in 2022. R&D expenses included $1.1 million and $4.4 million of certain non-cash expenses for the fourth quarter and full year ended December 31, 2023, respectively.
Selling, General and Administrative Expenses (SG&A) were $9.9 million and $35.5 million for the fourth quarter and full year ended December 31, 2023, respectively, as compared to $6.6 million and $27.0 million for the comparable periods in 2022. SG&A expenses included $1.4 million and $4.3 million of certain non-cash expenses for the fourth quarter and full year ended December 31, 2023, respectively.
Net Loss: X4 reported a net loss of $19.1 million and $101.2 million for the fourth quarter and full year ended December 31, 2023, respectively, as compared to $29.1 million and $93.9 million for the comparable periods in 2022. Net loss included $2.5 million and $8.7 million of stock-based compensation expenses for the fourth quarter and full year ended December 31, 2023, respectively.

About X4 Pharmaceuticals
X4 Pharmaceuticals is a late-stage clinical biopharmaceutical company driven to improve the lives of people with rare diseases of the immune system. Our lead clinical candidate is mavorixafor, a selective, small-molecule antagonist of chemokine receptor CXCR4 that is being developed as an oral, once-daily therapy across a variety of immunodeficiencies, including WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome and certain chronic neutropenic disorders. Following successful completion of a global, pivotal, Phase 3 clinical trial, we are seeking U.S. regulatory approval of oral, once-daily mavorixafor for the treatment of people aged 12 years and older with WHIM syndrome. We are also currently planning a Phase 3 clinical program evaluating mavorixafor in certain chronic neutropenic disorders. We continue to leverage our insights into CXCR4 and immune system biology at our corporate headquarters in Boston, Massachusetts and at our research center of excellence in Vienna, Austria.
