Official title MetfOrmin BenefIts Lower Extremities With Intermittent Claudication

ClinicalTrials.gov ID: NCT05132439

What this study is testing

What is Metformin ER?

This is an investigational oral medication being studied to see if it can help with leg pain caused by blocked arteries. It is designed to lower blood sugar and reduce inflammation in the body.

Also referred to as Glucophage.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study aims to find out if metformin can improve walking ability, slow the progression of blocked arteries, and reduce inflammation in the body.
Who it's for
The study is looking for veterans who have peripheral artery disease and experience leg pain when walking.
What's involved
Participants will be randomly assigned to take either metformin or a placebo pill, along with regular check-ups and tests to monitor their health.
Time commitment
The study involves regular visits over a set period to track changes in walking ability and health markers.
  • Phase 3: a large, late-stage study
  • Time commitment: about 12 months
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
