"We are excited that new survival data from 55 first-line pancreatic cancer patients treated with atebimetinib + mGnP in our Phase 2a clinical trial will be reported in an oral presentation at the ASCO Annual Meeting on June 1st," said Ben Zeskind, CEO of Immuneering. "We believe the upcoming presentation at ASCO is an excellent opportunity to build on the recent momentum in second-line pancreatic cancer and demonstrate atebimetinib's potential to provide a differentiated first-line option for patients. Our Phase 3 study of atebimetinib + mGnP in first-line pancreatic cancer patients, MAPKeeper 301, is now recruiting patients, and we remain on track to dose the first patient by mid-2026. Our Phase 2 lung cancer trial is on track to dose the first patient in the second half of the year. I believe we are entering a new era in cancer care where treatments have the potential to drive longer survival with fewer harsh side effects, and that atebimetinib will play an important role in that future."

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.

Immuneering Reports Phase 2a Trial Results for Atebimetinib
- 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.
