ENhancing Exercise With LIGHT to Improve Functioning in PAD

Status Recruiting

Clinical Trial Summary

Clinical Trial Description

The ENLIGHTEN PAD Trial will collect preliminary data to test whether daily 660 nm light treatment of the lower extremities immediately before home-based walking exercise sessions improves six-minute walk distance at 4-month follow-up, compared to sham light, in people with lower extremity peripheral artery disease (PAD) (Primary Aim #1). In Primary Aim #2, the investigators will measure the acute effect of the first treatment of 660 nm light on six-minute walk distance and on walking intensity (measured with the ActiGraph accelerometer) during the six-minute walk. In secondary and exploratory aims, the investigators will delineate biologic pathways by which 660 nm light enhances the benefits of home-based walking exercise, by measuring the effects of 660 nm light on exercise intensity during the exercise intervention and by measuring the effects of 660 nm light on plasma nitrosothiols, leg perfusion, and gastrocnemius muscle health and mitochondrial activity. Exercise intensity will be measured by the well validated ActiGraph accelerometer. The ENLIGHTEN PAD Trial is a Phase II multi-centered randomized clinical trial. Thirty-two participants with PAD will be randomized at one of two centers: Northwestern University (PI: MM McDermott, MD) and the University of Alabama (PI: Nicole Lohr MD, PhD) to either 660 nm light + home-based exercise or sham light + home-based exercise for four months. Both groups of participants will receive the same home-based high intensity walking exercise intervention. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
