"In Q1, we showed that IMM-1-104 can drive exceptional efficacy for patients with pancreatic cancer, including a third-line monotherapy patient with over 13 months progression-free survival, a second-line monotherapy patient with a confirmed partial response, and a first-line combination therapy patient with a confirmed complete response. These outcomes are particularly striking given the excellent tolerability observed with IMM-1-104. In January, we reported encouraging overall response rates and disease control rates for IMM-1-104 in combination with chemotherapy in first-line pancreatic cancer. We are excited to share survival data in a larger group of patients in the coming weeks," said Ben Zeskind, Ph.D., Co-founder and Chief Executive Officer of Immuneering.

"Our corporate progress in Q1 has matched the pace of our clinical progress. We announced a clinical supply agreement with Regeneron, expanded our cash runway into 2026, and hired an outstanding Chief Medical Officer as we plan for the initiation of a Phase 3 trial in first-line pancreatic cancer patients," Zeskind concluded.

Corporate Highlights

Pancreatic Cancer Patient Passes 13-month Mark on IMM-1-104 Monotherapy: In April, Immuneering provided an update on a Phase 1 pancreatic cancer patient in the third-line setting who has been receiving IMM-1-104 monotherapy for more than 13 months and is still on treatment. The patient – who previously experienced disease progression on first-line FOLFIRINOX and second-line Gem/Cis/nab-Pac – has been on IMM-1-104 monotherapy at 240 mg once daily and maintained stable disease including a RECIST SLD change of -28% and a 91% reduction in peak CA 19-9 levels. Treatment continued to be well tolerated by the patient, with approximately 16% weight gain.
Dr. Igor Matushansky Named as Chief Medical Officer: In March, Immuneering announced that Igor Matushansky, MD, PhD, an industry veteran with extensive global oncology drug development expertise and experience in clinical treatment of cancer patients, has been appointed the Company’s Chief Medical Officer. In this role, Dr. Matushansky is directing Immuneering’s clinical activities and is providing medical and operational leadership for the company’s development programs, including the ongoing Phase 2a trial of IMM-1-104 in pancreatic cancer, lung cancer, and melanoma, and plans to initiate a pivotal Phase 3 clinical trial in pancreatic cancer.
Clinical Trial Supply Agreement Announced with Regeneron for Libtayo (cemiplimab): In February, Immuneering announced a clinical trial supply agreement with Regeneron Pharmaceuticals for its anti-PD-1 therapy, Libtayo. The agreement supports the evaluation of IMM-1-104, in combination with Libtayo in patients with unresectable or metastatic RAS-mutant non-small cell lung cancer (NSCLC).
Provided a Positive Data Update from Three Pancreatic Cancer Arms of Ongoing Phase 2a Trial of IMM-1-104: In January, Immuneering announced positive data updates from three pancreatic cancer arms of its ongoing Phase 2a trial of lead program IMM-1-104 and confirmed plans to expand the Phase 2a trial to include additional combination arms.

First Quarter 2025 Financial Highlights

Cash Position: Cash and cash equivalents as of March 31, 2025, were $35.9 million, compared with $36.1 million as of December 31, 2024.
Research and Development (R&D) Expenses: R&D expenses for the first quarter of 2025 were $11.5 million compared with $11.2 million for the first quarter of 2024. The increase in R&D expenses was primarily attributable to higher clinical costs related to the Company’s lead program.
General and Administrative (G&A) Expenses: G&A expenses for the first quarter of 2025 were $4.0 million compared with $4.1 million for the first quarter of 2024. The decrease in G&A was primarily attributable to a decrease in the Company’s employee-related costs in connection with the general and administrative functions supporting the business.
Net Loss: Net loss attributable to common stockholders was $15.0 million, or $0.42 per share, for the first quarter ended March 31, 2025, compared to $14.3 million, or $0.49 per share, for the first quarter ended March 31, 2024.
