Glecirasib combined with sitneprotafib showed promising efficacy and manageable safety in patients with advanced KRASG12C -mutated NSCLC, particularly among those who had not received previous treatment. These findings support the evaluation of this combination in a phase 3 trial comparing this chemotherapy-free regimen to current standard of care in this patient group.
Olomorasib + pembrolizumab demonstrated manageable safety and promising antitumor activity in patients with KRAS G12C-mutant advanced NSCLC across PD-L1 expression levels, especially in the high PD-L1 first-line setting.
Recent phase I/II trials of KRAS G12C inhibitors have shown promising results, and the phase III CodeBreaK 300 study confirmed that sotorasib combined with panitumumab significantly improved efficacy compared with standard treatment, establishing a new therapeutic option for KRAS G12C-mutant metastatic CRC. Strategies under investigation include targeting alternative signaling pathways, developing next-generation inhibitors and specific degraders, and exploring multi-mechanism or multi-target combination strategies. This review systematically outlines the development of KRAS G12C inhibitors in mCRC, summarizes resistance mechanisms, and discusses emerging combination regimens, aiming to provide a theoretical basis and future directions for treatment optimization.
