Overview

In our research, we are delving into whether taking MitoQ for six months can improve the symptoms and function of people diagnosed with peripheral artery disease, especially those who suffer from leg pain while walking, known as intermittent claudication. We will be checking if MitoQ helps people with claudication walk better, be more active every day, feel better about their lives, and if it enhances the health of their leg muscles.

Description

This study will investigate whether taking MitoQ for six months can improve the walking ability, daily activity levels, and quality of life of people with claudication (leg pain) caused by peripheral artery disease (PAD). We'll also look at how MitoQ affects their calf muscles.

Here's what we'll be checking:

Muscle health: We'll examine muscle tissue samples under a microscope to see if MitoQ improves muscle health and function.

Body chemistry: We'll check blood tests to see if MitoQ affects overall health markers.

Mitochondrial health: We'll see if MitoQ reduces damage to mitochondria (the cell's powerhouses) and helps the body get rid of damaged ones. We'll also see if it improves how well mitochondria function.

Blood flow: We'll measure blood flow in the legs and see if MitoQ improves the function of tiny blood vessels in the calf muscles.

In short, we want to see if MitoQ can improve various aspects of health in people with claudication and PAD, and if these improvements are linked to better functioning mitochondria in their muscles.

Eligibility

Inclusion Criteria:

  1. a positive history of chronic claudication
  2. exercise-limiting claudication established by history and direct observation during a screening walking test administered by the evaluating vascular surgeon
  3. documented lower extremity arterial occlusive disease based on ankle/brachial index measurements and/or arterial imaging
  4. stable blood pressure, lipid and diabetes regimens and risk factor control for 6 weeks.

Exclusion Criteria:

  1. rest pain or tissue loss due to PAD (Fontaine stage III and IV)
  2. acute lower extremity ischemic event
  3. walking capacity significantly and primarily limited by conditions other than claudication including leg (joint/musculoskeletal, neurologic) and systemic (heart, lung disease) pathology.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
