CAMBRIDGE, Mass., March 01, 2024 (GLOBE NEWSWIRE) -- Immuneering Corporation (Nasdaq: IMRX), a clinical-stage oncology company seeking to develop and commercialize universal-RAS/RAF medicines for broad populations of cancer patients, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided recent business updates.
“We look forward to sharing topline data from the Phase 1 portion of the Phase 1/2a trial of IMM-1-104 this month. IMM-1-104’s unique deep cyclic inhibition mechanism was designed for broad universal-RAS activity and a differentiated safety profile. We believe this update will provide important insights on the primary and secondary endpoints of the Phase 1 portion of the trial, and is a key milestone that builds on the substantial progress made in 2023,” said Ben Zeskind, Chief Executive Officer, Immuneering. “Importantly, 2024 is shaping up to be even more exciting, as we look forward to data readouts from multiple arms of the expanded Phase 2a portion of our Phase 1/2a trial of IMM-1-104, and launch our Phase 1/2a trial of IMM-6-415.”
Full Year 2023 and Subsequent Corporate Highlights
Topline data from the Phase 1 portion of the Phase 1/2a clinical trial of IMM-1-104 expected in March 2024: The update is expected to include data on the primary and secondary endpoints of the Phase 1 portion of the Phase 1/2a trial (tolerability, candidate RP2D, and PK), as well as PD, circulating tumor DNA (ctDNA), and initial clinical activity data.
Dosing of the first patient in the expanded Phase 2a portion of the Phase 1/2a clinical trial of IMM-1-104 expected in March 2024: The clinical development plan for the trial was expanded in November 2023 to include 5 arms and additional clinical sites and investigators.
The Phase 2a portion of the trial is evaluating IMM-1-104 as a single-agent in approximately 90 patients across three arms:
IMM-1-104 monotherapy in patients with pancreatic ductal adenocarcinoma (PDAC) in the first- or second-line setting (n=30).
IMM-1-104 monotherapy in RAS-mutant melanoma in the second- or third-line setting after patients have received immunotherapy (n=30), or in the first line setting for patients who are not candidates for existing therapies.
IMM-1-104 monotherapy in RAS-mutant non-small cell lung cancer (NSCLC) in the second- or third-line setting (n=30).
The Phase 2a combination portion of the trial is evaluating approximately 60 PDAC patients in the first-line setting across two arms:
IMM-1-104 in combination with mFOLFIRINOX (n=30).
IMM-1-104 in combination with modified gemcitabine/nab-paclitaxel (n=30).
The first patient in the expanded Phase 2a portion of the Phase 1/2a study is expected to be dosed in March 2024, with initial data from multiple arms expected in 2024.
Received FDA Fast Track designation for IMM-1-104 in pancreatic cancer: In February 2024, Immuneering announced that the U.S. Food and Drug Administration (FDA) granted Fast Track Designation for its lead clinical-stage program, IMM-1-104, for the treatment of patients with pancreatic ductal adenocarcinoma (PDAC) who have failed one line of treatment. IMM-1-104 is designed to provide universal-RAS activity through deep cyclic inhibition of the MAPK pathway with once-daily oral dosing.
Dosing of the first patient in the Phase 1/2a clinical trial of IMM-6-415 expected in March 2024: The Phase 1 portion of the open-label trial is designed to evaluate the safety, tolerability, PK, and PD of IMM-6-415, as well as identify a candidate RP2D. The Phase 2a portion of the trial will further evaluate safety, tolerability, pharmacokinetics and clinical activity of IMM-6-415, all in patients with advanced solid tumors harboring RAF or RAS mutations. The Phase 1 portion of the clinical trial, which may enroll up to approximately 60 patients, will evaluate IMM-6-415 following a Bayesian mTPI-2 escalation design. Following the Company’s selection of the RP2D candidate, the Company expects to conduct a Phase 2a dose expansion phase in approximately 180 patients in multiple dose expansion arms.
Presented preclinical data demonstrating encouraging anti-tumor activity for IMM-1-104 and IMM-6-415: In October 2023, Immuneering presented preclinical data at AACR-NCI-EORTC. Expanded benchmarking of IMM-1-104 as a single agent across 193 patient-aligned models in humanized 3D-tumor growth assays demonstrated high sensitivity in a wide range of MAPK-driven tumors, including melanoma, pancreatic cancer and lung cancer. IMM-1-104 in combination with gemcitabine or paclitaxel drove enhanced anti-tumor activity in humanized 3D-tumor growth assays across multiple pancreatic cancer models. Benchmarking of IMM-6-415 as a single agent across more than 60 patient-aligned models in humanized 3D-tumor growth assays demonstrated high sensitivity in a wide range of MAPK-driven tumors, including models of RAS and RAF mutant disease. IMM-6-415 in combination with encorafenib drove deeper regressions and superior durability compared to binimetinib plus encorafenib in a head-to-head study in animal models of RAF mutant melanoma and colorectal cancer.
Completed dose escalation of the Phase 1 portion of the Phase 1/2a clinical trial evaluating IMM-1-104 for RAS-mutant, advanced solid tumors: In June 2023, the trial’s Safety Review Committee (SRC) completed its evaluation and observed that doses up to and including 320 mg once daily were tolerated with no dose-limiting toxicities. The dose evaluation portion of the trial was designed to evaluate two dosing cohorts of approximately 20 patients each at an oral dose of 240mg or 320mg once daily.
Raised $30 million in an underwritten offering: In April 2023, Immuneering completed an underwritten offering of 2,727,273 shares of its Class A common stock at an offering price of $11.00 per share. The aggregate net proceeds received by the Company from the offering were $28.2 million, after deducting underwriting discounts and commissions, but before deducting offering expenses payable by Immuneering.
Reported positive initial Phase 1 PK, PD, and safety data for IMM-1-104: In April 2023, Immuneering presented initial Phase 1 PK, PD, and safety data for IMM-1-104 at the American Association for Cancer Research (AACR) annual meeting. IMM-1-104 achieved significant levels of PK Cmax, demonstrated a half-life of approximately two hours, as predicted, and was well tolerated with no dose-limiting toxicities. These data support the potential of IMM-1-104 to drive deep cyclic inhibition of the MAPK pathway.

Fourth Quarter and Full Year 2023 Financial Highlights
Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2023 were $85.7 million, compared with $105.5 million as of December 31, 2022.
Research and Development (R&D) Expenses: R&D expenses for the fourth quarter of 2023 were $11.9 million compared with $9.9 million for the fourth quarter of 2022. Full year 2023 R&D expenses were $41.6 million compared to $36.3 million for full year 2022. The increase in R&D expenses from both periods of 2023 was primarily attributable to higher clinical costs related to the Company’s lead 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 2023 were $4.4 million compared with $4.1 million for the same period of 2022. Full year 2023 G&A expenses were $16.8 million compared to $15.6 million for full year 2022. The increase in G&A expenses for both periods of 2023 was primarily attributable to an increase in headcount in the Company’s general and administrative functions to support the business, and costs related to operating as a public company.
Net Loss: Net loss attributable to common stockholders was $15.1 million, or $0.52 per share, for the quarter ended December 31, 2023, compared to $13.2 million, or $0.50 per share, for the quarter ended December 31, 2022. Net loss attributable to common stockholders for full year 2023 was $53.5 million, or $1.88 per share compared to $50.5 million, or $1.91 per share, for full year 2022.
2024 Financial Guidance
Based on cash, cash equivalents and marketable securities, as of December 31, 2023, and current operating plans, the Company expects its cash runway to be sufficient to fund operations into the second half of 2025.
