ALX Oncology Reports Second Quarter 2021 Financial Results and Provides Clinical Development and Operational Highlights

BURLINGAME, Calif., Aug. 12, 2021 (GLOBE NEWSWIRE) -- ALX Oncology Holdings Inc., (“ALX Oncology”) (Nasdaq: ALXO) a clinical-stage immuno-oncology company developing therapies that block the CD47 checkpoint pathway, today reported financial results for the second quarter ended June 30, 2021 and provided clinical development and operational highlights.

“We are pleased to report on the substantial progress we made since the prior quarter with our lead product candidate, ALX148, and that the United States Adopted Names (USAN) Council has approved ‘evorpacept’ as the nonproprietary (generic) name for ALX148,” said Jaume Pons, Ph.D., Founder, President and Chief Executive Officer of ALX Oncology. “Our highlights include the presentation of additional positive Phase 1b data in second-line or greater HER2 positive gastric or gastroesophageal junction cancer from our ASPEN-01 trial during an oral session at the ESMO World Congress on Gastrointestinal Cancer; these results provide the basis for initiating a randomized Phase 2/3 trial in the same setting (ASPEN-06) scheduled to start in the second half of this year.”

“We recently dosed the first patient in our Phase 2 ASPEN-04 trial in first line metastatic or unresectable recurrent head and neck squamous cell carcinoma in combination with KEYTRUDA^® and chemotherapy, are continuing enrollment in our Phase 2 ASPEN-03 trial in first line metastatic or unresectable, PD-L1 positive recurrent head and neck cancer in combination with KEYTRUDA, and plan to present full results of the Phase 1b study (ASPEN-01) in the fourth quarter of this year. In addition, we plan to present results from our Phase 1 study in myelodysplastic syndromes, to initiate a Phase 2 study in the same setting (ASPEN-02), as well as to initiate a Phase 1 study in acute myeloid leukemia (ASPEN-05),” Dr. Pons continued.

Recent Clinical Developments for Evorpacept (Also known as ALX148)

• First Patient Dosed in Phase 2 ASPEN-04 Study
  • In July 2021, dosed first patient in the Phase 2 ASPEN-04 study evaluating the combination of evorpacept, a next generation CD47 blocker, with KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, and standard 5-fluorouracil and platinum chemotherapy for the first line (“1L”) treatment of patients with metastatic or unresectable, recurrent head and neck squamous cell carcinoma (“HNSCC”). In June 2021, the U.S. Food and Drug Administration (“FDA”) informed ALX Oncology that it reviewed its standard non-clinical safety study and has lifted the previously set partial clinical hold and cap on patient enrollment.

• First Patient Dosed in Phase 2 ASPEN-03 Study
  
  • In May 2021, dosed first patient in the Phase 2 ASPEN-03 study, which is also evaluating the efficacy of evorpacept in combination with KEYTRUDA (pembrolizumab) for the 1L treatment of patients with PD-L1 expressing metastatic or unresectable, recurrent HNSCC with a combined positive score (“CPS”) ≥ 1. In June 2021, the FDA informed ALX Oncology that it reviewed its standard non-clinical safety study and has lifted the previously set partial clinical hold and cap on patient enrollment.
    
• Data for Phase 1b ASPEN-01 Study Presented at 23^rd ESMO World Congress on Gastrointestinal Cancer
  • In July 2021, updated clinical data from the Phase 1b ASPEN-01 trial evaluating evorpacept in combination with trastuzumab and CYRAMZA^® (ramucirumab) for the treatment of gastric or gastroesophageal junction cancer (“G/GEJ”) were shared in an oral presentation at the 23^rd ESMO World Congress on Gastrointestinal Cancer. Data showed that evorpacept in combination with trastuzumab and ramucirumab is highly active and well-tolerated in patients with second line (“≥2L”) or greater HER2 positive G/GEJ cancer.
• Collaboration and Supply Agreement Entered with Eli Lilly
  • In June 2021, ALX Oncology entered into a clinical trial collaboration and supply agreement with Eli Lilly and Company to evaluate the combination of evorpacept with CYRAMZA (ramucirumab), Lilly’s anti-VEGFR2 antibody, for the treatment of patients with HER2 positive G/GEJ. Under the terms of the agreement, ALX Oncology will conduct a Phase 2/3 study to evaluate the efficacy of evorpacept in combination with ramucirumab, trastuzumab, and paclitaxel for the treatment of patients whose tumors have progressed following treatment of HER2 targeted therapy and chemotherapy. Lilly will supply ramucirumab for this trial.
    

Anticipated Key Milestones for Remainder of 2021

• Full results of a Phase 1b study of evorpacept in combination with Merck’s KEYTRUDA (pembrolizumab) and chemotherapy for the treatment of patients with HNSCC (ASPEN-01) are planned to be presented in the fourth quarter of 2021.
• Initiation of a Phase 1b clinical trial with evorpacept in combination with Zymeworks’ zanidatamab in patients with advanced HER2-expressing breast cancer and other solid tumors is expected in the second half of 2021.
• Initiation of a Phase 1 clinical trial evaluating evorpacept in combination with azacitidine and venetoclax in patients with acute myeloid leukemia (“AML”) (ASPEN-05) is planned in the second half of 2021.
• Initiation of a randomized Phase 2 trial of evorpacept in combination with Herceptin (trastuzumab), CYRAMZA (ramucirumab) and paclitaxel in second- or third-line treatment of patients with HER2-positive G/GEJ cancer (ASPEN-06) is expected in the second half of 2021.
• Results of a Phase 1 clinical trial of evorpacept in combination with azacitidine in patients with myelodysplastic syndromes (“MDS”) and the initiation of the Phase 2 clinical trial in MDS (ASPEN-02) are expected in the fourth quarter of 2021.
  

Second Quarter 2021 Financial Results:

• Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2021, were $410.0 million. ALX Oncology continues to believe its cash and cash equivalents is sufficient to fund planned operations through 2024.
• Net Loss: Generally accepted accounting principles (GAAP) net loss attributable to common stockholders was $16.3 million, or $0.40 per basic and diluted share and $14.0 million, or $4.41 per basic and diluted share for the three months ended June 30, 2021 and 2020, respectively. Non-GAAP net loss attributable to common stockholders was $14.0 million for the three months ended June 30, 2021, as compared to $10.7 million for the three months ended June 30, 2020. A reconciliation of GAAP to non-GAAP financial results can be found at the end of this news release.
• Related-party Revenue: Related-party revenue for the three months ended June 30, 2021 was nil compared to $0.5 million for the prior-year period. The decrease in related-party revenue relates to the termination of the Tollnine Agreement as of July 1, 2020.
• Research and Development (“R&D”) Expenses: R&D expenses consist primarily of pre-clinical, clinical and manufacturing expenses related to the development of evorpacept. These expenses for the three months ended June 30, 2021 were $11.2 million, compared to $7.7 million for the prior-year period. The increase of $3.5 million was primarily attributable to an increase of $3.7 million in clinical and development costs due to higher expenses associated with increased pre-clinical, clinical and other research costs in advancement of our current lead product candidate, evorpacept, an increased personnel-related costs of $1.1 million primarily due to headcount growth, and an increase of $0.3 million other research and development costs primarily driven by milestone payments triggered by the initiation of our Phase 2 trials, offset by a decrease of $1.6 million in stock-based compensation expense primarily resulting from the modification of stock options in the second quarter of 2020 whereas there was no such modification in 2021.
• General and Administrative (“G&A”) Expenses: G&A expenses consist primarily of administrative employee-related expenses, legal and other professional fees, patent filing and maintenance fees, and insurance. These expenses for the three months ended June 30, 2021 were $5.1 million, compared to $3.2 million for the prior-year period. This increase of $1.9 million was primarily attributable to an increase in stock-based compensation expense of $1.0 million primarily resulting from additional stock option award grants at higher fair values, an increase in personnel-related costs of $0.5 million due to headcount growth, and a $0.4 million increase in other general and administrative costs related to being a public company, including directors and officers liability insurance premiums.

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 Securities and Exchange Commission 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 attributable to common stockholders” is not based on any standardized methodology prescribed by GAAP and represent GAAP net loss adjusted to exclude (1) stock-based compensation expense, (2) accretion of term loan (interest expense related to ALX Oncology’s amortization of debt discount) and (3) mark-to-market adjustment on financial instruments (which include preferred stock warrants and derivatives). 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.
