- Trial Results: Immuneering Corporation presented Phase 2a trial results at the 2026 ASCO annual meeting, revealing that the combination of Atebimetinib and modified gemcitabine nab paclitaxel (mGnP) resulted in a median overall survival of 17.3 months in 55 patients, more than double the 8.5 months observed with mGnP alone, indicating significant potential in treating metastatic pancreatic ductal carcinoma.
- Efficacy Metrics: The trial also reported a median progression-free survival of 8.3 months, a disease control rate of 82%, and an objective response rate of 36%, suggesting that Atebimetinib may provide more durable anti-tumor activity and delay disease progression for patients.
- Safety Profile: The safety profile was manageable, with only two Grade 3 adverse events reported in about 10% of participants, and 84% of patients either maintained or gained weight during treatment, indicating good tolerability and potential for improved quality of life.
- Future Research Plans: The company is actively recruiting for the global, randomized Phase 3 MAPKeeper 301 trial to assess the Atebimetinib and mGnP combination, with the first patient expected to be dosed in mid-2026 and topline data anticipated in mid-2028, demonstrating ongoing commitment to advancing cancer treatment options.

About IMRX
Immuneering Corporation is a late-stage clinical oncology company, with an initial focus on patients with RAS, RAF and other mitogen-activated protein kinase (MAPK)-driven cancers. The Company's lead product candidate, atebimetinib (IMM-1-104), is an investigational, oral, once-daily Deep Cyclic Inhibitor of MEK. The Company is conducting a global randomized pivotal trial, MAPKeeper 301, evaluating atebimetinib in combination with chemotherapy in first-line pancreatic cancer patients. The Company's development pipeline also includes its additional clinical-stage product candidate envometinib (IMM-6-415) and other pre-clinical research programs, including research focused on validated core cancer-signaling pathways outside of the MAPK pathway. The Company's Deep Cyclic Inhibition (DCI) platform is enabled by two key elements: Bioinformatics and 3D Tumor Modeling. Its Deep Cyclic Inhibitors inhibit clinically-validated core signaling pathways, such as the MAPK pathway.
