The Company will present preclinical data evaluating MRTX1719, the selected clinical candidate from our MTA-cooperative PRMT5 inhibitor program, in MTAP-deleted cancer models.

In addition, the Company will present a summary of the discovery and characterization of initial formulations of MRTX1133, a KRASG12D inhibitor, including in pancreatic cancer models. The presentation will also include preliminary new clinical data from a cohort of the KRYSTAL-1 study evaluating adagrasib in previously-treated patients with KRASG12C-mutated pancreatic cancer.

About Adagrasib (MRTX849)
Adagrasib is an investigational, highly selective, and potent oral small-molecule inhibitor of KRASG12C that is optimized to sustain target inhibition, an attribute that could be important to treat KRASG12C-mutated cancers, as the KRASG12C protein regenerates every 24−48 hours. Adagrasib is a being evaluated as monotherapy and in combination with other anti-cancer therapies in patients with advanced KRASG12C-mutated solid tumors, including non-small cell lung cancer (NSCLC), colorectal cancer and pancreatic cancer.

About MRTX1133
MRTX1133 is an investigational, highly selective and potent small molecule inhibitor of KRASG12D. In preclinical studies, MRTX1133 exhibited a long half-life, an ability to bind the KRASG12D protein in both active and inactive states, and selective inhibition of KRAS G12D mutant cancer cells. In G12D mutant tumor models, MRTX1133 showed dose-dependent selective inhibition of the KRAS pathway and tumor regression. Increased activity was also shown when combined with rational combination therapies. MRTX1133 is in Investigational New Drug-enabling studies and has the potential to be a first-in-class therapeutic.

About MRTX1719
Mirati is developing MRTX1719, an internally discovered, synthetic lethal PRMT5 inhibitor for the treatment of methylthioadenosine phosphoylase (MTAP)-deleted cancers. PRMT5 is an enzyme critical to the survival of both healthy and cancer cells and is partially inhibited by methylthioadenosine (MTA), which accumulates in MTAP-deleted cancers. MRTX1719 has shown in preclinical models to selectively target the PRMT5/MTA complex in MTAP-deleted cancer cells while sparing healthy cells. MTAP gene deletion occurs in approximately 9% of all cancers including pancreatic, lung, and bladder cancers, as well as other patient populations that have limited treatment options. MRTX1719 is in Investigational New Drug-enabling studies and has the potential to be a first-in-class therapeutic.
