Perfusion Imaging for Peripheral Arterial Disease

Columbus, Ohio
The aim of this clinical study is to 1) establish a healthy database for nuclear perfusion imaging of the lower extremities and 2) assess the prognostic value of radiotracer-based perfusion imaging for predicting clinical outcomes in patients with peripheral artery disease (PAD) who are undergoing lower extremity revascularization procedures. We hypothesize that radiotracer imaging of the lower extremities will provide a sensitive non-invasive imaging tool for quantifying regional abnormalities in skeletal muscle perfusion and evaluating responses to medical treatment.

FAZA PET/MRI for Critical Limb Ischemia

Toronto, Ontario
Peripheral artery disease is a worldwide problem, leading to high mortality and mobility. Critical limb ischemia (CLI) is associated with high risk of amputation with the subsequent decreased in life quality. Endovascular therapy is now considered the primary treatment option in these patients to improve the vascularity and prevent amputations. In recent years, development of molecular imaging tools are now become available. A recent radio tracer named 18F-Fluoroazomycin Arabinoside (FAZA) its an specific marker of hypoxia in the tissues and has been used in multiples studies. This tracer can be used in PET/MR scan providing a potentially power diagnostic tool in patients with CLI, allowing in one diagnostic study the evaluation of location and degree of hypoxia in the extremity tissues. This diagnostic tool may offer a better assessment pre and post standard of care endovascular treatment for the patients. Moreover, some of the patients treated with endovascular therapy may not have a favorable outcome, without a clear reason explaining this situation. We will try to find some predictor model in the FAZA PET/MR that can explain the different outcomes and may help clinicians choose the best treatment option in specific cases. Thirdly, post processing for optimization of the MR sequences in patients with CLI will be performed at the MR component of the PET. There would thus be great clinical interest in developing non-invasive tools that could provide more accurate diagnostic information compared to traditional tests for these patients population.

Pressure Monitoring for Compartment Syndrome

Baltimore, Maryland
Acute compartment syndrome (ACS) is a surgical emergency that can develop in patients on extracorporeal membrane oxygenation (ECMO). ACS is a type of limb ischemia, which means that the limb, such as the arm or leg, loses blood flow. Patients on ECMO can develop this condition for many reasons, but most commonly from the ECMO procedure itself. This most commonly involves the leg. Key symptoms of ACS include severe pain, loss of pulses, loss of feeling, and inability to move the limb. However, because patients on ECMO are often sedated, ACS is difficult to diagnose as patients can not report symptoms. As a result, the only available tool for diagnosing ACS may be measurement of pressures in the limb. This is normally done with a needle-device, which is inserted into the leg for a single measurement. However, a recently developed device, called the MY01 Continuous Compartment Pressure Monitor, allows for continuous pressure readings instead of a single measurement. Multiple measurements may allow for much greater accuracy in diagnosing ACS, which may result in faster time to surgery and potentially save more limbs than single measurements. This device may also be less invasive than an older method of continuous pressure measuring, which uses a needle and tubing that is 14-gauge in size. Therefore, this study aims to compare 3 different types of methods for diagnosing ACS in patients on ECMO, which are 1) Standard of Care, 2) Standard of Care and MY01, and 3)Standard of Care and 14-gauge slit catheter.

Nutritional Supplements for Critical Limb Ischemia

Boston, Massachusetts
A prospective pilot study examining nutritional supplements among vascular surgery patients with Critical Limb Ischemia (CLI). CLI patients have a high rate of malnutrition and has the potential to benefit greatly from nutritional intervention. The investigators plan to evaluate nutrition and functional status of patients by assessing objective lab values and the use of the hand grip strength test. Providing perioperative nutritional supplements to patients has potentially improved their nutritional status, which in turn may improve the patient's clinical status after surgery.

Frequently Asked Questions

How much do Critical Limb Ischemia clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Critical Limb Ischemia clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Critical Limb Ischemia trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Critical Limb Ischemia is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Critical Limb Ischemia medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Critical Limb Ischemia clinical trials?

Most recently, we added Multifunctional Angioplasty for Peripheral Artery Disease, Sirolimus-Eluting Scaffold for Critical Limb Ischemia and Serranator Catheter for Critical Limb Ischemia to the Power online platform.
