Literature review of advances and challenges in KRAS G12C mutant non-small cell lung cancer. (PubMed, Transl Lung Cancer Res) - "The KRAS G12C mutation was once considered "undruggable" until the breakthrough approval of two targeted inhibitors: AMG510 (sotorasib) and MRTX849 (adagrasib). In China, IBI351 and D-1553 have also been approved for the treatment of adult patients with advanced NSCLC harboring the KRAS G12C mutation...Notably, recent findings indicate that combining dual immune checkpoint inhibitors (ICIs; durvalumab and tremelimumab) with chemotherapy (CT) in patients with advanced NSCLC, including those with KRAS mutations, can result in durable survival benefits...Moreover, the POSEIDON trial has highlighted the potential of dual ICI therapy combined with CT to achieve sustained clinical benefits. Despite these advances, the heterogeneity of tumor responses underscores the need for further investigation into intrinsic resistance mechanisms and the strategic optimization of combination therapies to enhance treatment outcomes."

Targeting AURKA, nuclear factor erythroid-2-related factor 2 (Nrf2), and phosphoserine aminotransferase 1 (PSAT1) in KRASG12C-mutant lung adenocarcinoma (ELCC 2025) - "Concurrent therapy of cetuximab and MRTX1133 (KRASG12D inhibitor) yields strong synergism in KRASG12D-mutant colorectal cancer...A cetuximab moonlight function in KRAS-mutant colorectal cancer inhibits nuclear factor erythroid-2-related factor 2 (Nrf2). The NSCLC KRAS mutant cell lines H358, H23 and H2030 were treated with fulzerasib or sotorasib in combination with cetuximab... AURKA and Nrf2 are reported to upregulate serine synthesis enzymes: phosphoglycerate dehydrogenase (PHGDH) and PSAT1. The current study concludes that cetuximab in combination with fulzerasib could exert a moonlight effect by blocking the in blocking Nrf2-SLC7A11, AURKA and serine synthesis pathways. The Nrf2-SLC7A11 and PSAT1 pathways are identified as potential mechanisms of resistance."
