Summary
Peripheral arterial disease (PAD) affects over 20% of aged adults and is very common among Veterans due significant tobacco use. PAD is due to the progressive blockage of peripheral arteries, predominantly to the legs, and results in intermittent claudication (IC) or recurrent muscle pain with activity secondary to insufficient blood supply. Those with PAD and IC experience a progressive decline in walking and poor quality of life. There is no effective medical treatment for PAD and IC. Metformin is a safe and effective treatment for Type 2 diabetes but it can also reduce inflammation, oxidative stress, and improve energy requirements as well as improve blood flow to the legs. Therefore, the investigators will test the ability of Metformin to improve overall functional status, reduce PAD progression, and reduce systemic inflammation in Veterans suffering from PAD and IC in a randomized, placebo controlled trial: Metformin BenefIts Lower Extremities with Intermittent Claudication (MOBILE IC) Trial. The success of this trial may identify a safe and effective treatment for PAD and IC.
Description
This is a quadruple blinded randomized controlled trial. Therefore, the allocation of participants to either placebo or metformin is unknown by the participant, research personnel, investigator, or blinded statistician. A total of 200 participants will be randomized over the course of 3 years. Study drug is administered to participants after all inclusion and no exclusion criteria is confirmed, informed consent is completed, and they are randomized. Study drug is continued throughout for 6 months following randomization. Participants are prospectively observed and monitored for 12 months after randomization. The patients' involvement (study visits/study phone calls) will last 12 months. Then, for 5 years, the study team will do a medical chart review as outlined in the ICF and protocol. All main study endpoints are within the 12-month time point. Secondary endpoints including MACE and MALE - major adverse cardiac and major adverse limb events - are time to event end points which can continue beyond the 12-month study time frame and will inform not only the effect of metformin on IC but also the natural history of IC among patients enrolled in the study.
