Immuneering Reports Third Quarter 2022 Financial Results and Recent Business Highlights

Recruiting has Commenced for Phase 1/2a Clinical Trial of IMM-1-104 in Advanced Solid Tumors with RAS Mutations (NCT05585320), with the First Patient Expected to be Dosed this Quarter

Shares Promising Preclinical Data on Second Program IMM-6-415 at the 37^th Annual Meeting of SITC, Demonstrating Preclinical Single Agent Activity in RAF and RAS Mutant Tumors and Enhancement of PD1 and CTLA4 Checkpoint Blockade

Cash, Cash Equivalents and Marketable Securities of $117.2M is Expected to Provide Cash Runway into Q3 2024

CAMBRIDGE, Mass., November 10, 2022— Immuneering Corporation (Nasdaq: IMRX), a biopharmaceutical company that aims to create medicines for all patients with solid tumors driven by RAS mutations and other MAPK pathway activation events, today reported financial results for the third quarter ended September 30, 2022, and provided recent business highlights. 

“The third quarter was a turning point for Immuneering as we submitted and cleared our first IND. Our Phase 1/2a trial for IMM-1-104 is now recruiting in what we believe is the first all-comers RAS clinical trial conducted to date,” said Ben Zeskind, Chief Executive Officer of Immuneering Corporation. “Cancer patients need new treatment options, regardless of the specific mutations in KRAS, NRAS, or HRAS that might be driving their tumors. IMM-1-104 has shown pan-RAS activity in preclinical studies with good tolerability.The conventional wisdom has been that a pan-RAS approach makes it difficult to avoid hitting wild-type RAS in healthy cells, but IMM-1-104’s novel deep cyclic inhibition mechanism aims to focus the therapeutic activity against RAS-driven malignant cells with the goal of largely sparing healthy cells.”

Dr. Zeskind continued, “Today, we also shared promising preclinical data on our second program IMM-6-415 at the 37^th Annual Meeting of SITC. IMM-6-415 is designed to target RAF and RAS mutant tumors as monotherapy and enhance therapeutic activity in select drug-drug combinations, including checkpoint inhibitors. We are very encouraged by this data and look forward to completing ongoing IND-enabling studies and expect to submit an IND for IMM-6-415 in Q4 2023.”

Corporate Highlights  

● IND Cleared for Phase 1/2a Trial of IMM-1-104 in September 2022; Clinical Trial (NCT05585320) is Recruiting, and First Patient is Expected to be Dosed this Quarter. On September 30, 2022, the company announced its IND application for IMM-1-104 had been cleared. The Phase 1/2a clinical trial is now recruiting and the company intends to dose its

first patient this quarter. The Phase 1/2a clinical trial will interrogate IMM-1-104's safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary anti-cancer activity for the treatment of advanced RAS mutant solid tumors. Five internationally recognized clinical sites in the United States will evaluate IMM-1-104 following a Bayesian mTPI-2 escalation design in order to determine a Recommended Phase 2 Dose. Following the Phase 1 portion, the company anticipates a dose expansion Phase 2a in RAS mutated pancreatic, melanoma, colorectal and lung cancers.

● IMM-6-415 Presentation at SITC. Today, Immuneering presented data on its second program, IMM-6-415, during a poster session at the 37th Annual Meeting of the Society for Immunotherapy of Cancer (SITC). IMM-6-415 demonstrates promising preclinical activity as a single agent in RAF and RAS mutant tumors and enhances PD1 and CTLA4 checkpoint blockade. IMM-6-415 is designed to provide deep cyclic inhibition of the MAPK pathway with an accelerated cadence relative to the once-daily dosing of IMM-1-104.

● Chief People Officer Appointed. In October 2022, the company announced the appointment of Leah R. Neufeld to the newly created Chief People Officer position. Ms. Neufeld brings decades of experience in life sciences as well as human resources and will join the senior leadership team in continuing to make the company a great place for the all-star team of Immuneers to work and grow, while also helping to add new talent as the company advances a robust pipeline of novel product candidates.

Key Development Highlights

● IMM-1-104 IND submission cleared in Q3 2022: The IND for IMM-1-104 cleared in under 30 days.

● First patient in Phase 1/2a trial expected to be dosed this quarter:Immuneering expects to dose the first patient in its Phase 1/2a clinical trial evaluating IMM-1-104 in advanced solid tumors with RAS mutations this quarter.

● Second IND submission for IMM-6-415 expected in Q4 2023: IMM-6-415 is currently in IND-enabling studies. Immuneering expects to file an IND application for IMM-6-415 in Q4 2023.

Third Quarter 2022 Financial Highlights 

● Cash Position: Cash and cash equivalents and marketable securities as of September 30, 2022, were $117.2 million, compared with $150.2 million as of December 31, 2021.   

● Research and Development (R&D) Expenses: R&D expenses for the third quarter ended September 30, 2022, were $9.4 million, compared with $6.2 million for the same period in

2021. The increase in R&D expenses was primarily attributable to higher preclinical costs related to the company’s lead programs and increased personnel to support ongoing research and development activities.

● General and Administrative (G&A) Expenses: G&A expenses for the third quarter ended September 30, 2022, were $3.8 million, compared with $2.6 million for the same period of 2021. The increase in G&A expenses was primarily attributable to an increase in headcount in the company’s general and administrative functions to support its business and to costs related to operating as a public company. 

● Net Loss: Net loss attributable to common stockholders was $12.8 million, or $0.49 per share, for the third quarter ended September 30, 2022, compared to $8.5 million, or $0.47 per share, for the third quarter ended September 30, 2021.  

2022 Financial Guidance  

● Immuneering expects full year GAAP operating expenses to be between $53.0 million and $56.0 million including estimated non-cash stock-based compensation. This compares to previous guidance of between $55.0 million and $60.0 million. The difference is primarily due to the timing of certain R&D expenses. Based on cash, cash equivalents and marketable securities as of September 30, 2022, and current operating plans, the company continues to expect its cash runway to extend into the third quarter of 2024. 

About Immuneering Corporation

Immuneering aims to create medicines for all patients with solid tumors driven by RAS mutations and other MAPK pathway activation events. Immuneering has more than a decade of experience applying translational bioinformatics to generate insights into drug mechanism of action and patient treatment response. Building on this experience, Immuneering’s disease-agnostic discovery platform enables the company to create product candidates based on 1) biological insights that are both counterintuitive and deeply rooted in data, and 2) novel chemistry. Immuneering’s lead product candidate, IMM-1-104, aims to achieve pan-RAS activity that selectively impacts cancer cells to a greater extent than healthy cells. IMM-1-104 is designed to be a highly selective third generation dual MEK inhibitor that modulates the signaling dynamics of the MAPK pathway by driving deep cyclic inhibition that deprives tumor cells of the sustained proliferative signaling required for rapid growth, while providing a cadenced, normalized level of signaling designed to spare healthy cells. IMM-1-104 is being developed to treat advanced solid tumors in patients harboring RAS mutations, and is translationally guided by Immuneering's proprietary, human-aligned 3D tumor modeling platform combined with patient-aligned bioinformatics. In addition to IMM-1-104, Immuneering is currently evaluating IMM-6-415 in IND-enabling studies. The earlier Immuneering drug discovery pipeline includes five additional oncology programs as well as two neuroscience programs.
