About Immuneering
Pharmaceutical Preparations, SIC 2834
The company is a clinical-stage oncology biotechnology firm that develops small-molecule cancer therapeutics called Deep Cyclic Inhibitors. Its drug discovery and development platform combines high-throughput bioinformatics with proprietary three-dimensional humanized tumor growth assays to target core cellular signaling pathways, primarily the mitogen-activated protein kinase cascade. Its lead clinical candidate is atebimetinib, an oral MEK inhibitor under evaluation for solid tumors such as pancreatic and lung cancers. The development pipeline also includes envometinib, an allosteric MEK inhibitor, alongside early-stage discovery programs. The company previously provided computational services to pharmaceutical and biotechnology collaborators, but now focuses on developing treatments for cancer patients.
The company conducts in vitro studies in its own laboratories and sponsors clinical trials globally for its investigational drug candidates.
