Adagrasib (MRTX849) is a potent, highly selective and orally available small molecule inhibitor of a form of KRAS that harbors an oncogenic substitution mutation (G12C). KRAS G12C is a well-validated driver mutation present in approximately 14% of NSCLC adenocarcinoma patients and 5% of CRC patients. 

Adagrasib has demonstrated broad-spectrum antitumor activity across a panel of KRAS G12C-positive patient- and cell-derived in vivo tumor models, including complete tumor regression in a subset of these models. MRTX849 is now in the clinic and has the potential to provide a long-awaited targeted therapy option for patients exhibiting a KRAS driver mutation.

Mirati has made adagrasib (MRTX849) available through and intermediate expanded access protocol (NCT 05162433) for patients ineligible for a clinical trial of adagrasib (MRTX849).  Additional information is available here.
