BOSTON, November 9, 2023 – 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 third quarter ended September 30, 2023 and highlighted key recent and upcoming expected milestones.
“We could not be more pleased with the significant milestones we’ve achieved in the clinical development of mavorixafor this year,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “Following the recent FDA acceptance of our New Drug Application seeking approval of mavorixafor for the treatment of WHIM syndrome, we are now preparing for a possible U.S. launch in the second quarter of 2024. With key learnings gleaned from our ongoing Phase 2 trial in chronic neutropenia and input from the FDA, we have now finalized the design of our planned pivotal, global Phase 3 trial evaluating mavorixafor in certain chronic neutropenic disorders and expect to initiate in the first half of 2024.”
Recent and Key Anticipated Milestones
Advancing Mavorixafor in WHIM Syndrome:
•In late October 2023, the United States Food and Drug Administration (FDA) accepted for filing X4’s New Drug Application (NDA) for once-daily, oral mavorixafor to treat individuals aged 12 and older with WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome, a rare, primary immunodeficiency. The FDA granted Priority Review of the mavorixafor NDA, 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. The FDA has notified X4 that it does not currently plan to hold an advisory committee meeting to review the filing.
•Due to mavorixafor’s Rare Pediatric Disease designation for WHIM syndrome in the U.S., X4 is eligible to receive a Priority Review Voucher (PRV) that can be used to obtain priority review for a subsequent application or can be sold to another drug sponsor, should mavorixafor be approved by the FDA for WHIM syndrome.
•In anticipation of a potential second quarter 2024 U.S. launch of mavorixafor in WHIM syndrome, X4 has continued to build out its go-to market organization, with key hires across commercial and medical functions, increased interactions with key stakeholders and rare disease patient advocacy organizations, and has launched a disease-awareness campaign called What If It’s WHIM? aimed at furthering the understanding of WHIM syndrome and educating patients and physicians on the importance and benefits of early diagnosis.
Advancing Mavorixafor in Chronic Neutropenic Disorders:
•Following an earlier presentation of preliminary data from the first 3 participants in the company’s ongoing Phase 2 trial evaluating the safety and efficacy of mavorixafor in certain chronic neutropenic disorders, the company anticipates presenting additional longer-term treatment data on these participants in a poster session at the upcoming 65th Annual Meeting of the American Society of Hematology (ASH), taking place December 9-12, 2023 in San Diego, CA.
•In addition, X4 plans to present efficacy and safety data from at least 15 of the currently enrolled participants in the Phase 2 chronic neutropenia trial during the first half of 2024.
•The design of a planned pivotal, global Phase 3 clinical trial evaluating the safety and efficacy of mavorixafor in the treatment of people 12 years and older with idiopathic or congenital neutropenia is now complete and incorporates FDA input. X4 anticipates initiation of this Phase 3 trial in the first half of 2024.
Other Recent Corporate Highlights:
•Management Team Strengthened with Addition of New Chief Medical Officer: In August 2023, X4 announced the appointment of Christophe Arbet-Engels, MD, PhD, as its new Chief Medical Officer. Dr. Arbet-Engels brings more than 25 years of experience to the company in strategic global drug discovery, development, and commercialization, as well as expertise in rare and orphan diseases.
•Completed a $115 million Debt Facility with Hercules Capital: In August 2023, X4 announced an expanded $115 million debt facility with Hercules Capital, with an initial drawdown of $22.5 million at closing.
•Expanded Company Board of Directors: In October 2023, X4 announced the addition of industry veteran R. Keith Woods to its Board of Directors bringing significant sales and commercial strategy experience most recently at argenx, where he helped build a global enterprise focused on developing treatments for rare autoimmune diseases and successfully launch the company’s flagship product, Vyvgart®.
Third-Quarter 2023 Results
•Cash, Cash Equivalents, Restricted Cash and Short Term Marketable Securities: X4 had $142.7 million in cash, cash equivalents, restricted cash, and marketable securities as of September 30, 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 $19.1 million for the third quarter ended September 30, 2023 as compared to $14.1 million for the comparable period in 2022. R&D expenses for the third quarter ended September 30, 2023 included $1.3 million of certain non-cash expenses.
•Selling, General, and Administrative Expenses (SG&A) were $8.1 million for the third quarter ended September 30, 2023 as compared to $6.0 million for the comparable period in 2022. SG&A expenses for the third quarter ended September 30, 2023 included $1.1 million of certain non-cash expenses.
•Net Loss: X4 reported a net loss of $2.3 million for the third quarter ended September 30, 2023, as compared to $21.6 million for the comparable period in 2022. Net losses in the current period include a non-cash gain of $25.2 million related to the company’s Class C warrant liability, which is adjusted to fair value each reporting period. Net losses also included $2.4 million of stock-based compensation expense.

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 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.
