- Reported positive data updates from its ongoing Phase 2a trial of lead program IMM-1-104, including encouraging responses in combination with chemotherapy in first-line pancreatic cancer - - Announced a clinical trial supply agreement with Regeneron Pharmaceuticals to evaluate IMM-1-104 in combination with Libtayo® (cemiplimab) in non-small cell lung cancer - - Additional IMM-1-104 Phase 2a data updates and initiation of new IMM-1-104 combination arms expected in 2025; planning underway for potential IMM-1-104 global pivotal trial - - Named industry veteran Dr. Igor Matushansky as Chief Medical Officer - - Cash runway extended into 2026 - CAMBRIDGE, Mass., March 20, 2025 (GLOBE NEWSWIRE) -- Immuneering Corporation (Nasdaq: IMRX), a clinical-stage oncology company seeking to develop and commercialize more effective and better tolerated therapies for cancer patients, today reported financial results for the fourth quarter and full year ended December 31, 2024, and provided recent business updates. “We were delighted to report updates from our ongoing Phase 2a trial of IMM-1-104 in January 2025 demonstrating excellent response rates for IMM-1-104 in combination with chemotherapy in first-line pancreatic cancer patients. Highlights of these data included an observed ORR of 43% and DCR of 86% for IMM-1-104 in combination with modified gemcitabine/nab-paclitaxel (mGnP) and an observed ORR of 50% for IMM-1-104 in combination with modified FOLFIRINOX (mFFX). Historic benchmarks for either chemotherapy agent alone are 23% ORR and 32% ORR, respectively. IMM-1-104 in combination with each of mGnP and mFFX was observed to be generally well tolerated. Based on these promising results, we have begun planning for a potential IMM-1-104 global pivotal trial in combination with modified gemcitabine/nab-paclitaxel in first-line pancreatic cancer, as we aim to get this exciting potential new treatment option to patients as quickly as possible,” said Ben Zeskind, Ph.D., Co-founder and Chief Executive Officer of Immuneering. “Importantly, the results demonstrated with IMM-1-104 to date point to its potential combinability, set to continue with our recently announced plans to study IMM-1-104 in combination with a BRAF inhibitor in melanoma, with a G12C inhibitor in non-small cell lung cancer, and with a PD-1 inhibitor in both melanoma and non-small cell lung cancer. We subsequently announced a clinical trial supply agreement with Regeneron for Libtayo in combination with IMM-1-104 in patients with non-small cell lung cancer and aim to get these new trials up and running this year. In support of these plans, we were pleased to announce that Dr. Igor Matushansky has joined Immuneering as Chief Medical Officer to oversee clinical activities, including medical and operational leadership for our development programs." Zeskind concluded: “As we look ahead to the rest of the year – with our cash balance recently fortified – we expect multiple data events, beginning with an update from our IMM-1-104 Phase 2a trial in the second quarter of 2025. We are continuing to build a growing data set that we believe positions our lead asset with the potential to offer an improved profile in comparison to current MEK inhibitors, which currently represents an existing approximately $2.4 billion annual global opportunity in the aggregate.” Corporate Highlights Phase 1 Pancreatic Cancer Patient Passes 13-month Mark on IMM-1-104 Monotherapy: Today, Immuneering provided a case study update for a Phase 1 pancreatic cancer patient in the third-line setting who has been receiving IMM-1-104 monotherapy for over 13 months so far. The patient – who previously progressed on first-line FOLFIRINOX and second-line Gem/Cis/nab-Pac – has been on IMM-1-104 monotherapy at 240 mg once daily. As of the most recent available scan, the patient has maintained stable disease with a RECIST SLD change of -24.2%. In addition to a 91% reduction in peak CA 19-9 levels, IMM-1-104 has been well tolerated by the patient, who has reported improved quality of life and approximately 12% weight gain. Named Dr. Igor Matushansky as Chief Medical Officer: In March, Immuneering announced that Igor Matushansky, MD, PhD, joined the company as Chief Medical Officer. In this role, Dr. Matushansky will direct Immuneering’s clinical activities, providing medical and operational leadership for the company’s development programs including the ongoing Phase 2a study of IMM-1-104 in pancreatic cancer, lung cancer, and melanoma, and plans to initiate a pivotal Phase 3 clinical trial in pancreatic cancer. Announced Clinical Trial Supply Agreement with Regeneron Pharmaceuticals to Evaluate IMM-1-104 in Combination with 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 intended evaluation of Immuneering’s lead product candidate, IMM-1-104, in combination with Libtayo in patients with unresectable or metastatic RAS-mutant non-small cell lung cancer (NSCLC). Positive Data Update from Three Pancreatic Cancer Arms of Ongoing Phase 2a Trial of IMM-1-104: In January, Immuneering announced a positive data update from three pancreatic cancer arms of its ongoing Phase 2a trial of lead program IMM-1-104, as well as plans to expand the Phase 2a trial to include additional combination arms. Launched Pancreatic Cancer Advisory Board: In December, Immuneering announced the formation of its Pancreatic Cancer Advisory Board. The advisory board, which comprises world-renowned oncology clinical researchers, will provide strategic medical and clinical guidance to the company as its pipeline, including lead clinical program IMM-1-104, continues to advance. FDA Fast Track Designation for IMM-1-104 in Advanced Melanoma: In December, the U.S. Food and Drug Administration (FDA) granted Fast Track designation for IMM-1-104, as a treatment for patients with unresectable or metastatic NRAS-mutant melanoma who have progressed on or are intolerant to PD-1/PD-L1 based immune checkpoint inhibitors. FDA Orphan Drug Designation for IMM-1-104 in the Treatment of Pancreatic Cancer: In October 2024, the FDA granted Orphan Drug designation to IMM-1-104 in the treatment of pancreatic cancer. Near-Term Milestone Expectations IMM-1-104 Further IMM-1-104 Phase 2a data expected in the second quarter of 2025. Initiation of Phase 2a arm of IMM-1-104 in combination with Libtayo in NSCLC planned for 2025. Initiation of Phase 2a arm of IMM-1-104 in combination with a G12C inhibitor in NSCLC planned for 2025. Initiation of Phase 2a arm of IMM-1-104 in combination with a PD-1 inhibitor in melanoma planned for 2025. Initiation of Phase 2a arm of IMM-1-104 in combination with a BRAF inhibitor in melanoma planned for 2025. Fourth Quarter and Full Year 2024 Financial Highlights Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2024, were $36.1 million, compared with $85.7 million as of December 31, 2023. These amounts exclude net proceeds of $13.7 million from the Company’s ATM facility raised in January 2025. Research and Development (R&D) Expenses: R&D expenses for the fourth quarter of 2024 were $14.9 million compared with $11.9 million for the fourth quarter of 2023. Full year 2023 R&D expenses were $48.0 million compared to $41.6 million for full year 2023. The increase in fourth quarter and full year 2024 R&D expenses as compared to the same respective periods of 2023 was primarily attributable to higher clinical costs related to the Company’s lead IMM-1-104 program and increased personnel to support ongoing research and development activities. General and Administrative (G&A) Expenses: G&A expenses for the fourth quarter of 2024 were $3.7 million compared with $4.4 million for the fourth quarter of 2023. Full year 2024 G&A expenses were $16.1 million compared to $16.8 million for full year 2023. The decrease in fourth quarter and full year 2024 G&A expenses as compared to the same respective periods of 2023 was primarily due to lower external professional fees and a reduction in employee-related costs, partially offset by higher stock-based compensation related to the general and administrative functions supporting the business. Net Loss: Net loss attributable to common stockholders was $18.1 million, or $0.58 per share, for the quarter ended December 31, 2024, compared to $15.1 million, or $0.52 per share, for the quarter ended December 31, 2023. Net loss attributable to common stockholders for full year 2024 was $61.0 million, or $2.04 per share, compared to $53.5 million, or $1.88 per share, for full year 2023. 2025 Financial Guidance Based on cash and cash equivalents as of December 31, 2024, plus proceeds from the Company’s subsequent utilization of its ATM facility, and current operating plans, the Company expects its cash runway to be sufficient to fund operations into 2026.
