Study Summary

The purpose of this study is to determine anti-tumor activity by measuring overall response rate in recurrent and/or metastatic HNSCC patients receiving the combination of metformin and pembrolizumab.

Primary Outcome

A complete response is defined as the disappearance of all target lesions, with any affected lymph nodes reduced to less than 10 mm. A partial response occurs when there is at least a 30% reduction in the total size of target lesions compared with baseline. Progressive disease is indicated by at least a 20% increase in lesion size (with a minimum absolute increase of 5 mm) or the appearance of new lesions. Stable disease describes cases where tumor size changes do not meet criteria for partial r
