Patients With Heart Failure ANd Type 2 Diabetes Treated With Placebo Or Metformin (PHANTOM) Pilot Study

Summary

To conduct a pilot study to evaluate the feasibility of a large randomized controlled trial (RCT) of metformin in patients with heart failure and type 2 diabetes and to generate initial morbidity and mortality estimates in this patient population. The primary hypothesis is that subjects with heart failure and type 2 diabetes who receive metformin will have a significant reduction in the combined endpoint of all-cause mortality and all-cause hospitalization as compared to subjects who receive placebo therapy.
