Mechanistically, galangin suppressed M2 macrophage polarization, directly interacted with the efferocytosis-related targets CAMK2A and MERTK, and reduced their expression. Together, these findings establish efferocytosis as a novel and targetable vulnerability in drug-resistant NSCLC and highlight galangin as a promising sensitizer for overcoming resistance to two major targeted therapies.
Improvement from ECOG PS 2 to ECOG PS 0 to 1 was observed by the end of first cycle of treatment (57.9%). Safety and efficacy outcomes of sotorasib in this study were not affected with ECOG PS 2 and the history of CNS metastases and were consistent with those reported in key clinical trials.
However, pioneering work by Shokat and colleagues has led to the discovery of KRAS G12C-GDP mutant specific inhibitors, with two such inhibitors adagrasib and sotorasib now FDA approved for treatment of non-small cell lung cancer (NSCLC). Recent studies support the view that integration of AI algorithms with experimental methods is a key aspect in stream-lining the drug discovery process and identifying molecules with greater structural diversity, less off target effects than traditional screening methods. Furthermore, the authors believe that AI will eventually become standardized in drug discovery and existing pipelines specific to KRAS mutant inhibitor design will be expanded for additional KRAS mutations as well as other aggressive driver oncogenes across multiple cancers.
Sotorasib-protein conjugates were strongly localized to the villous epithelial cells of the small intestine but were scarcely detected in the colon, highlighting regional differences. This study elucidates the localization of sotorasib-protein conjugates in the gastrointestinal tract of rats and provides important insights into the mechanisms underlying sotorasib-induced gastrointestinal disorders.
A 71-year-old woman with a medical history of metastatic non-small cell lung cancer treated with left-side pneumonectomy 10 years ago, stereotactic body radiation therapy of a single right lung metastasis 7 years ago, and targeted therapy with sotorasib for the last 6 years (+KRAS G12C tumor), obesity (BMI of 33), and OSA on nocturnal CPAP, presents to the pulmonary office with dyspnea.
