P2.02-03 A Phase II Study of Metformin with Pemetrexed/Carboplatin in Patients with Metastatic Non-Squamous Non-Small Cell Lung Cancer

There is a subset of NSCLC patients ineligible for benefit from TKIs/Immunotherapy (e.g. STK11 mutation conferring resistance to Immunotherapy). Besides, many patients cannot afford these therapies. Metformin has anticancer properties acting both on glycolytic metabolism and tumor microenvironment. In vitro studies suggest synergism between metformin and pemetrexed. STK11 deficient cell lines are more sensitive to metformin. Clinical studies combining metformin with chemotherapy are limited by small sample size.
