Dueling KRASG12C Inhibitors Achieve Responses.

Clinical trials of two KRASG12C inhibitors, MRTX849 and AMG 510, have shown robust efficacy in phase I trials including patients with non-small cell lung cancer. Data on the effectiveness of the drugs in other tumor types, such as colorectal cancer, have been more limited. Regardless, researchers are excited about the possibility of targeting proteins long thought "undruggable." ©2020 American Association for Cancer Research.
