Generation of actionable, cancer-specific neoantigens from KRAS(G12C) with adagrasib.

ABSTRACT: Effective immune therapy against cancer ideally should target a cancer-specific antigen, an antigen that is present exclusively in cancer cells. However, there is a paucity of cancer-specific antigens that are endogenously produced. HapImmune™ technology utilizes covalent inhibitors directed to an intracellular cancer driver to create cancer-specific neoantigens in the form of drug-peptide conjugates presented by class I MHC molecules. Our previous study with sotorasib, an FDA-approved covalent inhibitor of KRAS(G12C), demonstrated that drug-treated cells produce such neoantigens and can be killed by T cell engagers directed against the drug-peptide/MHC complex. Thus, this technology can unite targeted and immune therapies. In the present study, we examined whether this approach could gene
