• Higher SG&A expenses: $13.3 million in Q2 2024 vs $10.2 million in Q2 2023

Financial Analyst

X4 Pharmaceuticals' Q2 2024 results show a significant financial turnaround, primarily due to the $105 million sale of their priority review voucher. This one-time gain propelled them from a net loss to a $90.8 million net income. However, it's important to note that this is not recurring revenue.

The company's cash position of $169.5 million provides a runway into late 2025, which is positive for near-term stability. The initial $0.6 million in XOLREMDI sales is modest but marks the beginning of recurring revenue. R&D expenses increased by 33.97% year-over-year, indicating continued investment in pipeline development.

While the financial picture has improved, investors should focus on future XOLREMDI sales growth and the progression of the chronic neutropenia trials as key indicators of long-term value.

Medical Research Analyst

The approval and launch of XOLREMDI for WHIM syndrome represent a significant milestone in rare disease treatment. As the first therapy targeting the underlying cause of WHIM, it has the potential to become the standard of care for this patient population.

The positive interim data from the Phase 2 trial in chronic neutropenia (CN) is particularly promising. The ability of mavorixafor to increase neutrophil counts both as monotherapy and in combination with G-CSF suggests a potential paradigm shift in CN treatment. The initiation of the Phase 3 4WARD trial further solidifies this potential.

The upcoming full Phase 2 data in November 2024 and the progress of the Phase 3 trial will be critical in determining mavorixafor's efficacy across a broader CN population. This could significantly expand X4's market opportunity beyond WHIM syndrome.

Market Research Analyst

X4 Pharmaceuticals' transition to a commercial-stage company with XOLREMDI's launch marks a pivotal moment in its corporate evolution. The rare disease market, particularly for primary immunodeficiencies, is characterized by high unmet need and potential for premium pricing.

The company's focus on maximizing global opportunities, including plans for EMA submission, indicates a strategic approach to market expansion. However, the success of XOLREMDI will depend on effective patient identification and market penetration strategies, given the rarity of WHIM syndrome.

The potential expansion into chronic neutropenia represents a significant market opportunity, as it's a broader indication than WHIM syndrome. If successful, mavorixafor could compete with or complement existing G-CSF treatments, potentially capturing a substantial share of this market.

Investors should monitor the execution of X4's commercialization strategy and the progress of their pipeline to gauge long-term growth potential.

BOSTON, Aug. 08, 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 second quarter ended June 30, 2024 and highlighted key recent and upcoming expected milestones.

Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals commented on the company’s significant accomplishments in the second quarter of 2024: “When we founded X4 ten years ago, we had a vision to advance our lead asset, an orally active CXCR4 antagonist called mavorixafor, to help those with rare diseases and few to no treatment options. This past quarter, we were able to realize this vision, receiving U.S. approval of mavorixafor (as XOLREMDI™) in WHIM syndrome, a rare primary immunodeficiency. The U.S. launch of XOLREMDI is now underway with our commercial team in place and executing on our strategy, and with WHIM patients 12 years and older now being treated with the only therapy indicated for and targeting the underlying cause of their disease.”

Dr. Ragan continued: “We also made tremendous progress this quarter in the development of mavorixafor for those with chronic neutropenia, not only demonstrating for the first time the ability of mavorixafor to durably and meaningfully increase neutrophil counts in people living with chronic neutropenia (CN), but also initiating a global, pivotal Phase 3 trial in CN. All of these accomplishments mark a significant step forward for X4, now a fully integrated biopharmaceutical company, as we continue to explore additional uses for and maximize the global potential of mavorixafor for patients.”

Recent and Key Anticipated Upcoming Milestones

XOLREMDI™ (mavorixafor) in WHIM Syndrome, a Rare Primary Immunodeficiency:

• FDA Approval of XOLREMDI. In April 2024, X4 announced that the U.S. Food and Drug Administration (FDA) approved XOLREMDI™ (mavorixafor) capsules for use in patients 12 years of age and older with WHIM syndrome (warts, hypogammaglobulinemia, infections and myelokathexis) to increase the number of circulating mature neutrophils and lymphocytes.
• U.S. Launch Update: X4 is currently executing its U.S. launch of XOLREMDI and generating its first revenues from product sales. Launch efforts have included: increasing interactions with targeted physicians and rare disease patient advocacy groups, continuing disease awareness and education campaigns, and activating its X4Connect™ and nurse educator programs, which provide a suite of patient support services.
• 4WHIM Phase 3 Data Publications. During the second quarter of 2024, data from the company’s completed global, pivotal Phase 3 4WHIM clinical trial were published online in Blood, the journal of the American Society of Hematology (ASH), and new data from the trial and its open-label extension phase were presented at the annual meeting of the Clinical Immunological Society (CIS).
• Maximizing the Global Opportunity in WHIM Syndrome. X4 currently expects to submit for regulatory approval of mavorixafor in WHIM syndrome from the European Medicines Agency (EMA) by early 2025, while also exploring additional potential opportunities in geographies where the company may be able to efficiently leverage its U.S. FDA approval.

Advancing Mavorixafor in Chronic Neutropenic Disorders:

• Positive Interim Phase 2 Clinical Data. In June 2024, X4 presented positive clinical data from its ongoing Phase 2 clinical trial evaluating the safety and efficacy of mavorixafor in the treatment of people with chronic neutropenia (CN). The interim results showed that once-daily oral mavorixafor was generally well tolerated and durably increased participants’ absolute neutrophil counts (ANC) both as a monotherapy and in combination with stable doses of injectable granulocyte colony-stimulating factor (G-CSF), the only therapy approved in the U.S. for severe chronic neutropenia.
• Full Phase 2 Data Expected in November 2024. Data from the completed Phase 2 CN trial, including data from the group of participants receiving mavorixafor and dose-adjusted G-CSF, are expected to be presented in November 2024.
• Initiation of Phase 3 4WARD Trial. In June 2024, the company also announced the initiation of its global, pivotal Phase 3 clinical trial (NCT06056297), evaluating the efficacy, safety, and tolerability of oral, once-daily mavorixafor (with or without stable doses of G-CSF) in people with congenital, acquired primary autoimmune, or idiopathic CN who are experiencing recurrent and/or serious infections. The 52-week 4WARD trial is a randomized, double-blind, placebo-controlled, multicenter study aiming to enroll 150 participants.
  

Second Quarter 2024 Financial Results

• Gain on Sale of Non-Financial Asset: In May 2024, X4 recognized a gain on the sale of a priority review voucher (PRV) to a third party for $105.0 million in cash. The PRV was awarded to X4 by the FDA under its Rare Pediatric Disease program upon the approval of XOLREMDI. Under this program, the FDA awards PRVs to sponsors of rare pediatric disease product applications that meet certain criteria to encourage development of new drugs and biologics for the prevention and treatment of rare pediatric diseases.
• Cash, Cash Equivalents, Restricted Cash and Short-Term Marketable Securities: X4 had $169.5 million in cash, cash equivalents, restricted cash, and short-term marketable securities as of June 30, 2024. X4 believes it has sufficient funds to support company operations into late 2025 and notes that this projected runway does not include potential future XOLREMDI revenue.
• Revenue and Cost of Revenue: For the three months ended June 30, 2024, X4 reported net product revenue of $0.6 million and cost of revenue of $0.3 million related to the sale of XOLREMDI. Cost of revenue includes approximately $0.2 million of license costs, including sale-based royalties and operational milestones capitalized as an intangible asset and amortized over the life of the underlying intellectual property. X4 did not report product revenue or cost of revenue in any prior period.
• Research and Development (R&D) Expenses were $20.9 million for the second quarter ended June 30, 2024 as compared to $15.6 million for the comparable period in 2023. R&D expenses for the second quarter ended June 30, 2024 included $1.2 million of certain non-cash expenses.
• Selling, General, and Administrative Expenses (SG&A) were $13.3 million for the second quarter ended June 30, 2024 as compared to $10.2 million for the comparable period in 2023. SG&A expenses for the second quarter ended June 30, 2024 included $1.2 million of certain non-cash expenses.
• Net Income (Loss): X4 reported net income of $90.8 million for the second quarter ended June 30, 2024, as compared to a net loss of $55.7 million for the comparable period in 2023. Net income in the current period includes the sale of a PRV for $105.0 million, as noted above, and a non-cash gain of $20.2 million related to the fair value remeasurement of the company’s Class C warrant liability.

About XOLREMDI™ (mavorixafor)
XOLREMDI (mavorixafor) is a selective CXCR4 receptor antagonist approved in the U.S. for use in patients 12 years of age and older with WHIM syndrome to increase the number of circulating mature neutrophils and lymphocytes. CXCR4 receptor stimulation by its ligand, CXCL12, has been shown to play a key role in the movement of white blood cells (leukocytes) to and from the bone marrow compartment. Full prescribing and safety information for XOLREMDI can be found at www.xolremdi.com.

About WHIM Syndrome
WHIM syndrome is a rare, combined primary immunodeficiency and chronic neutropenic disorder caused by CXCR4 receptor dysfunction that results in impaired mobilization of white blood cells from the bone marrow into peripheral circulation. WHIM syndrome is named for its four classic manifestations: warts, hypogammaglobulinemia, infections, and myelokathexis, although only a minority of patients experience all four manifestations in the acronym. People with WHIM syndrome characteristically have low blood levels of neutrophils (neutropenia) and lymphocytes (lymphopenia), and as a result, experience serious and/or frequent infections.

About Chronic Neutropenia and Mavorixafor
Chronic neutropenia is a rare blood condition lasting more than three months, persistently or intermittently, and characterized by increased risk of infections and reduced quality of life due to abnormally low levels of neutrophils circulating in the blood. Neutrophils are retained in the bone marrow by the CXCR4/CXCL12 axis, creating a reserve of cells. Downregulation of the CXCR4 receptor by mavorixafor, an orally active CXCR4 antagonist, has been shown to mobilize neutrophils from the bone marrow into the peripheral blood across multiple disease states. The level of circulating neutrophils is typically measured by drawing blood to determine the absolute neutrophil count (ANC).

About the 4WARD Global, Pivotal, Phase 3 Clinical Trial
The 4WARD trial is a global, pivotal Phase 3 clinical trial (NCT06056297) evaluating the efficacy, safety, and tolerability of oral, once-daily mavorixafor (with or without G-CSF) in people with congenital, acquired primary autoimmune, or idiopathic chronic neutropenia who are experiencing recurrent and/or serious infections. The 52-week trial is a randomized, double-blind, placebo-controlled, multicenter study aiming to enroll 150 participants with confirmed trough ANC levels less than 1,500 cells per microliter at baseline screening and histories of two or more serious and/or recurrent infections in the prior year. The primary endpoint of the trial is based on two outcome measures: annualized infection rate and positive ANC response.
