Abstract
The KRAS p.G12C mutation occurs in seen in 13% of non-small cell lung cancers (NSCLCs) and in approximately 1%–3% of colorectal and other cancers. Until the last decade, there were no approved therapies for targeting the KRAS mutation, but recently, drugs targeting the mutation have been discovered. KRAS is a small protein structurally without any deep pockets making it almost impossible to target. Furthermore, it binds in its active state with the GTP protein, with remarkably close affinity making blockage of the KRAS mutation challenging. Sotorasib is a nanomolecule that selectively and irreversibly targets the KRAS mutation. The phase 2 trial (CodeBreaK100) conducted in a total of 129 patients with advanced solid tumors harboring the KRAS p.G12C mutation showed anticancer activity in patients following multiple lines of treatment. We searched for the articles published online between 2018 and May 2021 with keywords, “KRAS mutation,” “lung cancer,” and “sotorasib.” In this review article, we have discussed the history, pharmacokinetics, dosing, important studies, toxicities, and other pertinent details of sotorasib.
