- Rare Resistance Mechanisms: Among 123 patients treated with atebimetinib, very few exhibited MAPK pathway mutations commonly associated with RAS inhibitors, indicating lower resistance in first-line treatment and enhancing its clinical application potential.
- Diverse Resistance Patterns: In 86 patients receiving monotherapy and 37 patients undergoing combination therapy, resistance mechanisms did not converge on the RAS/MAPK pathway but instead displayed a variety of non-MAPK pathways, showcasing atebimetinib's unique anti-tumor mechanisms.
- Limited Early Adaptive Resistance: ctDNA analysis revealed minimal early molecular evolution during treatment, suggesting that atebimetinib imposes less selective pressure, potentially improving treatment durability by reducing adaptive resistance.
- Clinical Trial Progress: Immuneering expects to initiate its pivotal MAPKeeper 301 Phase 3 trial in mid-2026, evaluating the efficacy of atebimetinib combined with modified gemcitabine/nab-paclitaxel in first-line metastatic pancreatic cancer, further validating its clinical value.

About IMRX
Immuneering Corporation is a clinical-stage oncology company. The Company is engaged in the development of medicines for cancer patients with universal-RAS therapy. The Company’s lead product candidate, IMM-1-104, is in under Phase I/IIa clinical trial in patients with advanced solid tumors harboring RAS mutations. IMM-1-104 is being developed as a once-daily oral monotherapy that aims to achieve universal-RAS activity through deep cyclic inhibition of the mitogen-activated protein kinase (MAPK) pathway. The Company’s second product candidate, IMM-6-415, is an oral, twice-daily deep cyclic inhibitor of mitogen-activated protein kinase kinase (MEK) in a Phase I/IIa trial in patients with advanced solid tumors harboring RAS or RAF mutations. Its pipeline also includes RAS modulators and other small molecule drug discovery programs. The Company’s platform is enabled by two key elements: Bioinformatics and 3D Tumor Modeling.

Immuneering Presents Promising Data for Cancer Drug Atebimetinib
- Clinical Trial Data: Immuneering Corporation presented clinical trial data for its cancer drug Atebimetinib at the American Association of Cancer Research annual meeting, involving 123 patients, with 86 on monotherapy and 37 on combination therapy, indicating the drug's potential in anti-tumor activity.
- Resistance Mechanism Analysis: The data revealed that acquired mutations in tumor cells during treatment primarily occurred in non-MAPK pathways, suggesting that Atebimetinib may provide more durable effects in inhibiting tumor cell proliferation, potentially leading to longer survival for patients.
- Key Trial Progress: The company anticipates initiating the pivotal Phase 3 MAPKeeper 301 trial by mid-2026 to evaluate the efficacy of Atebimetinib combined with modified Gemcitabine/nab-Paclitaxel in treating first-line metastatic pancreatic cancer patients.
- Future Trial Plans: Immuneering also plans to begin a Phase 2 trial for Atebimetinib in the second half of this year, targeting first-line RAS-mutant non-small cell lung cancer patients, further validating its clinical application potential.
