Rhea-AI Filing Summary

ALX Oncology Holdings Inc. reported first quarter 2026 results showing a significantly narrower loss while advancing its cancer pipeline. GAAP net loss was $17.9 million, or $0.17 per share, compared with $30.8 million, or $0.58 per share, a year earlier. Non-GAAP net loss improved to $15.4 million from $25.5 million.

Research and development expenses fell to $13.6 million from $23.9 million, and general and administrative costs declined to $5.4 million from $7.9 million, mainly due to prior workforce reductions and pipeline prioritization. Cash, cash equivalents and investments totaled $169.1 million as of March 31, 2026, and the company expects this to fund operations through the first half of 2028.

Clinically, exploratory Phase 1b/2 data for CD47-inhibitor evorpacept plus zanidatamab in heavily pre-treated HER2-positive metastatic breast cancer showed a confirmed objective response rate of 60% and median progression-free survival of 8.3 months in centrally confirmed HER2-positive patients. All patients with HER2-positive disease and high CD47 expression responded, with a median duration of response of 20.2 months. The Phase 2 ASPEN-09-Breast trial remains on track for topline data in mid-2027, and the Phase 1 trial of EGFR-targeted ADC ALX2004 continues toward safety data in the second half of 2026.

Insights

ALX Oncology narrowed losses, strengthened its balance sheet, and reported encouraging biomarker-driven breast cancer data.

ALX Oncology cut its GAAP net loss to $17.9 million from $30.8 million, driven by lower R&D and G&A expenses after workforce and pipeline rationalization. Non-GAAP net loss improved similarly, and cash, cash equivalents and investments rose to $169.1 million, supporting operations through the first half of 2028.

Exploratory Phase 1b/2 results combining evorpacept with zanidatamab in heavily pre-treated HER2-positive metastatic breast cancer showed a 60% confirmed objective response rate and 8.3-month median progression-free survival in centrally confirmed HER2-positive patients. High CD47 expression appeared associated with particularly durable responses, aligning with prior ASPEN-06 gastric cancer findings and supporting a biomarker-driven strategy.

A February 2026 equity offering generated $150 million in gross proceeds and $140.4 million in net proceeds, materially lifting stockholders’ equity to $151.3 million. Ongoing milestones include Phase 1 ALX2004 safety data in the second half of 2026 and ASPEN-09-Breast topline data in mid-2027.

Evorpacept cORR in ccHER2-positive 60% Confirmed objective response rate in ccHER2-positive mBC subgroup
objective response rate medical
"The confirmed objective response rate (cORR) among all 24 patients was 33%"
The objective response rate (ORR) is the percentage of patients in a clinical trial whose tumors measurably shrink or disappear according to preset rules. Investors use it as a quick, objective signal of a drug’s ability to produce a clear treatment effect—like counting how many plants visibly respond after applying a new fertilizer—and higher ORR can improve odds of regulatory approval, commercial success, and company valuation.
progression free survival medical
"the median progression free survival (mPFS) was 3.6 months"
Progression free survival is the length of time during and after a treatment when a disease, such as cancer, does not get worse or spread. It is an important measure because longer periods of stability can indicate that a treatment is effectively controlling the condition. For investors, it provides insight into the potential durability and success of a therapy or medication.
antibody-drug conjugate medical
"ALX2004, a novel antibody-drug conjugate (ADC) for the treatment of EGFR-expressing solid tumors"
An antibody-drug conjugate is a targeted medicine that combines an antibody, which can identify specific cells, with a powerful drug designed to destroy those cells. This approach allows for precise treatment, minimizing damage to healthy tissue. For investors, developments in this area can signal advances in cancer therapies and potential growth opportunities in the biotech sector.

SOUTH SAN FRANCISCO, Calif., May 8, 2026 (GLOBE NEWSWIRE) – ALX Oncology Holdings Inc. (“ALX Oncology” Nasdaq: ALXO), a clinical-stage biotechnology company advancing a pipeline of novel therapies designed to treat cancer and extend patients’ lives, today reported financial results for the first quarter ended March 31, 2026, and provided a corporate update.

 

“We are encouraged by the data presented yesterday at the ESMO Breast Cancer 2026 congress, which reinforce the potential of our CD47-inhibitor evorpacept to provide durable responses in patients with HER2-positive cancers that express high levels of CD47,” said Jason Lettmann, Chief Executive Officer at ALX Oncology. “Coupled with the previous results from the ASPEN-06 gastric cancer trial, these findings validate our development strategy and reinforce our confidence in the ongoing Phase 2 ASPEN-09-Breast trial. Additionally, we are pleased with the progress of the Phase 1 trial for ALX2004, which remains on track to report dose-escalation safety data this year. With a strengthened balance sheet, we are well-positioned to deliver key data readouts from both ongoing clinical programs.”

 

“It is encouraging to see clinical improvements in patients with heavily pre-treated HER2-positive breast cancer. As the landscape for HER2-positive advanced breast cancer continues to evolve, there remains a clear need for new options once patients’ disease progresses following treatment with currently available therapies, including trastuzumab deruxtecan,” said Sara Hurvitz, M.D., Professor, Senior Vice President and Director, Clinical Research Division and Smith Family Endowed Chair in Women’s Health at Fred Hutchinson Cancer Center, University of Washington. “The findings from this Phase 1b/2 trial suggest that

combining evorpacept with HER2-targeted agents, guided by CD47 biomarker-driven selection, may offer a promising strategy to address this unmet need.”

 

ALX Oncology Q1 2026 Highlights and Recent Developments

Evorpacept

Data from exploratory analyses in the Phase 1b/2 clinical trial evaluating the company’s investigational CD47-inhibitor evorpacept in combination with Jazz Pharmaceuticals’ zanidatamab (ZIIHERA®) in patients with heavily pre-treated metastatic breast cancer (mBC), all of whom had received prior ENHERTU® (fam-trastuzumab deruxtecan-nxki) therapy, were presented for the first time in a poster session at the ESMO Breast Cancer 2026 congress on Thursday, May 7. The findings show that patients with centrally confirmed HER2-positive (ccHER2-positive) mBC and high CD47 expression experienced promising, durable responses.
The exploratory analyses comprised 24 patients, including 10 with ccHER2-positive disease. Seventeen of 24 samples were evaluable for CD47 expression, including samples from nine of the 10 ccHER2-positive patients. Patients received zanidatamab plus evorpacept at dosages of 20 mg/kg (n=3) or 30 mg/kg (n=21). As of the August 1 2024 data cut-off, key findings from the analyses include:
o
The confirmed objective response rate (cORR) among all 24 patients was 33% and the median progression free survival (mPFS) was 3.6 months.
o
Patients with ccHER2-positive disease (n=10) had higher response rates, with a cORR of 60% and mPFS of 8.3 months.
o
All of the patients (n=5/5) with ccHER2-positive disease and high CD47 expression (defined as total membrane staining of >20%) responded (including one complete response and four partial responses), with a median duration of response (mDOR) of 20.2 months and mPFS of 22.1 months. In comparison, among the patients with ccHER2-positive disease and low CD47 expression (defined as total membrane staining of <20%), cORR was 25% (n=1/4) and mPFS was 3.4 months.
The findings are consistent with previous results from the randomized ASPEN-06 trial in HER2-positive gastric cancer, which indicated CD47 was predictive of evorpacept activity, and support a biomarker-driven approach. Together, these two independent trials suggest that adding evorpacept can yield positive, durable responses in heavily pretreated HER2-positive patients.
The ongoing ASPEN-09-Breast Phase 2 trial evaluating evorpacept plus trastuzumab and physician’s choice of chemotherapy in patients with HER2-positive breast cancer previously treated with ENHERTU is designed to enable this biomarker-driven approach. Enrollment in the trial remains on track globally and the Company expects to provide topline data for 80 patients in mid-2027.

ALX2004

The dose-escalation portion of the Phase 1 trial of ALX2004, a novel antibody-drug conjugate (ADC) for the treatment of epidermal growth factor receptor (EGFR)-expressing solid tumors, continues to enroll patients at ascending dose levels and is on track to report safety data in 2H 2026.

First Quarter 2026 Financial Results

Cash, Cash Equivalents and Investments: Cash, cash equivalents and investments as of March 31, 2026, were $169.1 million. The Company believes its cash, cash equivalents and investments are sufficient to fund planned operations through the first half of 2028.
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 product candidates, evorpacept and ALX2004, and R&D personnel-related expenses, including stock-based compensation. R&D expenses for the three months ended March 31, 2026 were $13.6 million

compared to $23.9 million for the prior-year period, or a decrease of $10.3 million. This decrease was primarily attributable to a decrease of $4.4 million in personnel and related costs driven by the reduction in workforce in early 2025, a decrease of $2.3 million in clinical and development costs due to change in clinical development strategy reducing the number of active clinical trials, a decrease of $1.8 million in stock-based compensation expense, and a decrease of $1.3 million in preclinical costs due to pipeline prioritization strategy.
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 March 31, 2026 were $5.4 million compared to $7.9 million for the prior year period, or a decrease of $2.6 million. This decrease was primarily attributable to a decrease of $1.0 million in personnel and related costs driven by the reduction in workforce in early 2025, a decrease of $0.9 million in stock-based compensation expense, and a decrease of $0.7 million in legal and corporate costs.
Net loss: GAAP net loss was ($17.9) million for the three months ended March 31, 2026, or ($0.17) per basic and diluted share, as compared to a GAAP net loss of ($30.8) million for the three months ended March 31, 2025, or ($0.58) per basic and diluted share. The lower net loss is primarily attributed to lower R&D expenses. Non-GAAP net loss was ($15.4) million for the three months ended March 31, 2026, as compared to a non-GAAP net loss of ($25.5) million for the three months ended March 31, 2025. 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.
