Metformin Plus/Minus Fasting Mimicking Diet to Target the Metabolic Vulnerabilities of LKB1-inactive Lung Adenocarcinoma

Non-randomizedParallel-groupOpen-labelTreatment

Summary

Lung adenocarcinoma with inactive LKB1 has emerged as a particularly aggressive form of lung cancer, with poor response to immune checkpoint inhibitors. Recent preclinical evidences have demonstrated that LKB1-inactive lung adenocarcinoma is characterized by specific metabolic vulnerabilities, which make it hypersensitive to energetic crisis. For instance, by inhibiting mitochondrial metabolism and reducing ATP availability to cancer cells, the antidiabetic compound metformin has anticancer activity and prevents acquired resistance to cisplatin in lung adenocarcinoma with inactive LKB1. Similarly to metformin, glucose starvation, which can be recapitulated in vivo by cyclic fasting or fasting-mimicking diet (FMD), can cause metabolic crisis in these neoplasms. In this trial, the investigators will assess for the first time the efficacy of combining standard-of-care platinum-based chemoimmunotherapy with metformin plus/minus FMD in patients with LKB1-inactive, advanced lung adenocarcinoma.
