SOUTH SAN FRANCISCO, Calif., March 06, 2025 (GLOBE NEWSWIRE) -- ALX Oncology Holdings Inc., (“ALX Oncology” or “the Company”) (Nasdaq: ALXO), a clinical-stage biotechnology company advancing therapies that boost the immune system to treat cancer and extend patients’ lives, today reported financial results for the fourth quarter and full year ended December 31, 2024, and provided a corporate update.

“In 2024, we delivered strong progress and continued momentum for our clinical development program evaluating evorpacept as a potential first- and best-in-class CD47 blocker with the ability to deepen and enhance responses to a variety of important, available therapies across a wide range of cancer types,” said Jason Lettmann, Chief Executive Officer of ALX Oncology. “With multiple important clinical trial readouts, significant momentum for our ongoing clinical studies and key additions to our leadership team, we have positioned ALX Oncology for near- and long-term success. Yesterday during our R&D Day webcast, we shared updates on how we are prioritizing operations and capital to support our new and ongoing clinical programs that are expected to extend our cash runway into the fourth quarter of 2026, including taking the difficult decision to streamline our organization aligned to these priorities.”

Fourth Quarter 2024 Highlights and Recent Developments

• At the 2025 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium in January 2025, reported updated results from the multi-center, international ASPEN-06 Phase 2 clinical trial (NCT05002127) evaluating evorpacept in combination with HERCEPTIN^® (trastuzumab), CYRAMZA^® (ramucirumab) and paclitaxel (Evo-TRP) against trastuzumab, CYRAMZA (ramucirumab) and paclitaxel (TRP) for the treatment of patients with HER2-positive gastric/gastroesophageal junction (GEJ) cancer, where all patients had received an anti-HER2 agent in prior lines of therapy.
  • Data highlighted evorpacept as the first CD47-blocker to show substantial tumor response and a well-tolerated safety profile in a prospective randomized trial.
  • Greatest benefit observed among patients with confirmed HER2-positive cancer, as demonstrated by either fresh biopsy or ctDNA HER2-expression, with a confirmed objective response rate (cORR) of 48.9% and median duration of response (mDOR) of 15.7 months vs. 24.5% ORR and mDOR of 9.1 months in the control group, and a progression-free survival Hazard Ratio of 0.64.
  • Evo-TRP was generally well tolerated, with the incidence of adverse events in the evorpacept population consistent with those in TRP control.
• At the San Antonio Breast Cancer Symposium (SABCS) 2024, presented new data from the Phase 1b/2 clinical trial demonstrating evorpacept in combination with zanidatamab generates promising antitumor activity in metastatic breast cancer (mBC).
  • Patients who were HER2-positive by central assessment (n=9) showed the greatest anti-tumor activity with a cORR of 55.6% and a median progression-free survival (mPFS) of 7.4 months.
  • Combination therapy was well tolerated with a manageable safety profile consistent with prior experience with each investigational agent.
• Announced strategic prioritization and resource optimization efforts, including approximately 30% workforce reduction primarily in preclinical research, expected to extend cash runway into Q4 2026.
• Announced key additions to our leadership team and Board of Directors throughout 2024 and early 2025.
  • Allison Dillon, Ph.D., an experienced drug development, commercial strategy and business development leader, as Chief Business Officer.
  • Alan Sandler, M.D., a distinguished leader with more than 30 years of experience in oncology and drug development, as Chief Medical Officer.
  • Harish Shantharam, CFA, a proven biotech industry executive with over two decades of senior leadership experience in finance, commercial and corporate operations, as Chief Financial Officer.
  • Barbara Klencke, M.D., a seasoned clinical leader in oncology drug development with more than 20 years of industry experience, appointed to ALX Oncology’s Board of Directors.
  • Chris H. Takimoto, M.D., Ph.D., FACP, a distinguished researcher and drug developer with a proven track record in oncology with 17 years of industry experience, appointed to ALX Oncology’s Board of Directors.
• Announced that Jaume Pons, Ph.D., Founder, President and Chief Scientific Officer, will be departing from his current position and transitioning to the role of Senior Scientific Advisor in Q2 2025.

2024 Full Year and Fourth Quarter Financial Results:

• Cash, Cash Equivalents and Investments: Cash, cash equivalents and investments as of December 31, 2024, were $131.3 million. The Company believes its cash, cash equivalents and investments are sufficient to fund planned operations into Q4 of 2026. Potential impact of near-term catalysts related to ASPEN-03/04 HNSCC read out and FDA interaction on ASPEN-06 (for e.g., gastric cancer accelerated approval and/or Phase 3 initiation) are excluded from cash runway guidance.
• Research and Development (“R&D”) Expenses: R&D expenses consist primarily of preclinical, clinical and development costs related to the development of the Company’s current lead product candidate, evorpacept, and R&D personnel-related expenses including stock-based compensation. R&D expenses for the three months ended December 31, 2024 were $23.5 million compared to $41.8 million for the prior-year period or a decrease of $18.3 million. This decrease was primarily attributable to a decrease of $17.3 million in clinical and development costs primarily due to less manufacturing of clinical trial materials to support active clinical trials for our lead product candidate, evorpacept, and a decrease in stock-based compensation expense slightly offset by increased preclinical costs for development of new targets and increased personnel and related costs. R&D expenses for the year ended December 31, 2024 were $116.4 million, compared to $141.8 million for the prior-year period.
• General and Administrative (“G&A”) Expenses: G&A expenses consist primarily of administrative personnel-related expenses, including stock-based compensation and other costs such as legal and other professional fees, patent filing and maintenance fees, and insurance. G&A expenses for the three months ended December 31, 2024 were $7.1 million compared to $6.2 million for the prior year period or an increase of $0.8 million. This increase was primarily attributable to an increase in personnel and related costs. G&A expenses for the year ended December 31, 2024 were $26.1 million compared to $28.5 million for the prior-year period.
• Net loss: GAAP net loss was ($29.2) million for the three months ended December 31, 2024, or ($0.55) per basic and diluted share, as compared to a GAAP net loss of ($45.5) million for the three months ended December 31, 2023, or ($0.93) per basic and diluted share. The lower net loss is primarily attributed to lower R&D expenses. GAAP net loss was ($134.9) million for the year ended December 31, 2024, or ($2.58) per basic and diluted share, as compared to a GAAP net loss of ($160.8) million for the year ended December 31, 2023, or ($3.74) per basic and diluted share. Non-GAAP net loss was ($23.2) million for the three months ended December 31, 2024, as compared to a non-GAAP net loss of ($38.7) million for the three months ended December 31, 2023. Non-GAAP net loss was ($107.5) million for the year ended December 31, 2024, as compared to a non-GAAP net loss of ($134.3) million for the year ended December 31, 2023. A reconciliation of GAAP to non-GAAP financial results can be found at the end of this news release.

Use of Non-GAAP Financial Measures

We supplement our consolidated financial statements presented on a GAAP basis by providing additional measures which may be considered “non-GAAP” financial measures under applicable SEC rules. We believe that the disclosure of these non-GAAP financial measures provides our investors with additional information that reflects the amounts and financial basis upon which our management assesses and operates our business. These non-GAAP financial measures are not in accordance with generally accepted accounting principles and should not be viewed in isolation or as a substitute for reported, or GAAP, net loss, and are not a substitute for, or superior to, measures of financial performance performed in conformity with GAAP.

“Non-GAAP net loss” is not based on any standardized methodology prescribed by GAAP and represents GAAP net loss adjusted to exclude stock-based compensation expense and accretion of term loan discount and issuance costs. Non-GAAP financial measures used by ALX Oncology may be calculated differently from, and therefore may not be comparable to, non-GAAP measures used by other companies.
