Study Summary

Metformin is used widely in the treatment of type 2 diabetes. It has off-label indications for use in the prevention of diabetes and in hyperinsulinar obesity. In medical practices, the implementation of metformin for these off-label indications is variable, often at the level of the provider. Multiple retrospective investigations have also shown a clinical benefit in men with prostate cancer who are incidentally treated with metformin. This pragmatic study will test the feasibility of enrolling patients who have glucose intolerance (as defined by HbA1c of 5.7-6.4%) and/or who have increased BMI (BMI greater than or equal to 25 kg/m2) to a randomized pragmatic study of metformin plus lifestyle modification information versus lifestyle modification information only. For purposes of the scope of this project and the study's feasibility, this will be implemented in a group of prostate cancer patients, who may have additional benefits from metformin.

Primary Outcome

Once there are 6 months of follow-up data on the first 100 patients, a formal analysis will be done to determine the completeness of data and the potential for a powered study. Outcome measure was amended January 2025.
