Sotorasib-d7 (AMG-510-d7) is a deuterium-labeled Sotorasib. Sotorasib (AMG-510) is a first-in-class, orally bioavailable, and selective KRAS G12C covalent inhibitor. Sotorasib irreversibly inhibits KRAS G12C by locking it in an inactive GDP-bound state. Sotorasib leads to the regression of KRAS G12C‑mutated locally advanced or metastatic non‑small cell lung cancer (NSCLC)[2][3].
