AACR 2024: Adagrasib Plus Cetuximab in KRAS G12C–Mutated Colorectal Cancer
The combination of adagrasib and cetuximab may show clinical activity and promising survival outcomes in patients with metastatic, heavily pretreated, KRAS G12C–mutated colorectal cancer.
Patients with metastatic, heavily pretreated KRAS G12C–mutated colorectal cancer showed promising survival outcomes when treated with the combination of the KRAS G12C inhibitor adagrasib and the anti-EGFR antibody cetuximab. The phase I/II KRYSTAL-1 trial revealed that the objective response rate was 34%, the disease control rate was 85.1%, and the responses lasted a median of 5.8 months. The adagrasib plus cetuximab combination therapy is currently under Priority Review by the U.S. Food and Drug Administration and also being evaluated in the phase III KRYSTAL-10 trial (ClinicalTrials.gov identifier NCT04793958).
