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.
