Immunome Reports Second Quarter 2026 Financial Results and Provides Business Update
August 11, 2026
•
Varegacestat PDUFA target action date set for April 28, 2027, following U.S. FDA acceptance of New Drug Application (NDA) for adults with desmoid tumors
•
Detailed Phase 3 RINGSIDE data presented in an oral session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, demonstrating statistically significant improvements across the primary and all key secondary endpoints
•
First patient dosed in June 2026 in Phase 1 trial of IM-1617, a potential first-in-class solid tumor antibody-drug conjugate incorporating HC74, Immunome’s proprietary TOP1 inhibitor payload
•
First patient dosed in July 2026 in Phase 1 trial of IM-3050, an investigational fibroblast activation protein (FAP)-targeted radioligand therapy designed to deliver radioactive lutetium-177 directly to FAP-expressing cells
BOTHELL, Wash. – Immunome, Inc. (Nasdaq: IMNM), a biotechnology company focused on developing first-in-class and best-in-class targeted cancer therapies, today announced financial results for the quarter ended June 30, 2026, and provided a business update.
“We continue to execute against our strategy of building a diversified targeted oncology company with multiple opportunities to bring needed therapies to patients,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer of Immunome. “For varegacestat, the presentation of detailed Phase 3 RINGSIDE data at ASCO and subsequent FDA acceptance of our NDA with a PDUFA target action date of April 28, 2027 represent important steps toward a potential approval and launch. We are also continuing to advance our broader pipeline, with three additional clinical-stage programs now enrolling patients. We believe this momentum positions us well for a milestone-rich second half of 2026.”
Pipeline Highlights
Varegacestat:
•
In July 2026, the U.S. FDA accepted Immunome’s NDA for varegacestat for the treatment of adults with desmoid tumors and assigned a PDUFA target action date of April 28, 2027.
•
Immunome plans to submit a Marketing Authorization Application to the European Medicines Agency for varegacestat by the end of 2026.
•
Detailed efficacy and safety results from the Phase 3 RINGSIDE trial of varegacestat in patients with progressing desmoid tumors were presented in an oral abstract session at the 2026 ASCO Annual Meeting.
o
RINGSIDE met its primary endpoint, with varegacestat demonstrating a statistically significant and clinically meaningful 84% reduction in the risk of disease progression or death vs. placebo (hazard ratio = 0.16, p<0.0001)
o
Progression-free survival benefit was consistent across prespecified patient subgroups, including tumor location, baseline tumor size, patient age and prior systemic desmoid tumor therapy
o
The trial met all key secondary endpoints, including a confirmed objective response rate of 56% vs. 9% with placebo (p<0.0001), as assessed by blinded independent central review
o
Varegacestat demonstrated statistically significant improvement in worst pain intensity at week 12, with a clinically significant difference observed as early as the first evaluation at week 4
IM-1021: The Phase 1 clinical trial of IM-1021 is ongoing, with objective responses observed in participants with B-cell lymphoma at multiple dose levels. Immunome expects to present initial lymphoma data for IM-1021 in 2026.
IM-1617: In June 2026, the first patient was dosed in the Phase 1, first-in-human trial evaluating IM-1617 in patients with advanced solid tumors. The study is designed to evaluate safety, tolerability, pharmacokinetics and preliminary anti-tumor activity and is expected to include participants with advanced solid tumors, including colorectal cancer, non-small cell lung cancer and breast cancer.
IM-3050: In July 2026, the first patient was dosed in the Phase 1, first-in-human trial evaluating IM-3050 in patients with FAP-expressing advanced solid tumors. The trial is designed to evaluate safety, tolerability, dosimetry, pharmacokinetics and preliminary anti-tumor activity of the investigational FAP-targeted radioligand therapy.
Preclinical ADC Pipeline: Immunome expects to submit Investigational New Drug applications (INDs) for IM-1340 and IM-1335 in mid- and late 2026, respectively. The programs are each directed at undisclosed solid tumor targets and incorporate HC74. Additional undisclosed ADCs are in discovery and lead optimization to support INDs in 2027 and beyond.
Second Quarter 2026 Financial Results
•
As of June 30, 2026, cash, cash equivalents and marketable securities totaled $520.0 million. Immunome expects its current cash position to fund operations into 2028.
•
Research and development expenses for the quarter ended June 30, 2026, were $59.9 million, including stock-based compensation expense of $4.2 million.
•
General and administrative expenses for the quarter ended June 30, 2026, were $18.3 million, including stock-based compensation expense of $4.6 million.
•
Immunome reported a net loss of $73.1 million for the quarter ended June 30, 2026.
