- KRASG12D mutations impact approximately 180,000 patients in the US and Europe, representing approximately a 2.5-fold increase in prevalence compared to KRASG12C mutations.
- MRTX1133 is a highly potent investigational inhibitor of the KRASG12D driver mutation and demonstrated selective and reversible inhibition of KRASG12D in both its active and inactive states.
- In addition, MRTX1133 administration resulted in marked tumor response in preclinical KRASG12D mutated pancreatic cancer models as well as lung and colorectal cancer models.
- The Phase 1/2 clinical trial will launch in early 2023 with plans for multiple expansion cohorts in pancreatic, colorectal, lung and other KRASG12D tumor types.
