How does Sotorasib work?
Sotorasib is a KRAS G12C inhibitor. KRAS is a protein in your body that sends signals to your cells to grow and divide. In certain lung cancers, a mutation (change) in KRAS called G12C leads to uncontrolled cell growth. Sotorasib attaches to KRAS proteins with the G12C mutation. By doing so, the medication helps block tumor growth.
