Overview

MIKE-1 is an oral combination regimen consisting of the biguanide metformin and the multi-component fluoropyrimidine S-1 (a combination of tegafur, gimeracil, and oteracil). Developed for the treatment of unresectable pancreatic adenocarcinoma, MIKE-1 is typically evaluated in combination with standard chemotherapy agents like gemcitabine and nab-paclitaxel. The rationale behind the combination is that metformin may enhance the efficacy of chemotherapy by activating AMP-activated protein kinase (AMPK) and inhibiting the mTOR pathway, which are often dysregulated in pancreatic cancer cells. S-1 provides a sustained release of 5-fluorouracil (5-FU) while incorporating gimeracil to inhibit its degradation and oteracil to reduce gastrointestinal toxicity. This combination aims to improve survival outcomes in patients with previously untreated, advanced pancreatic cancer.
