Brief Summary
The purpose of this trial is to evaluate the safety and efficacy of sonodynamic therapy (SDT) in reducing atherosclerotic plaques inflammation and increasing peak walking time (PWT) among peripheral a...
Detailed Description
Atherosclerotic lower extremity PAD affects more than 20 million people in the world. PAD is associated with a major decline in functional status and claudication is the most frequent symptom. Current...
Eligibility Criteria
Inclusion
- Patients with atherosclerotic peripheral artery disease with symptoms of moderate to severe intermittent claudication (defined as ability to walk at least 2, but not more than 11, minutes on a graded treadmill test using the Gardner protocol)
- Aged ≥40 years
- Resting ABI \< 0.9 or ABI decreases \> 0.15 after treadmill test regardless of the ABI at rest
- Presence of significant stenosis but not occlusion of femoropopliteal arteries including the common femoral artery, superficial femoral artery and popliteal artery as determined by: Duplex ultrasound imaging OR lower extremity computed Tomography Angiography (CTA) OR lower extremity magnetic resonance angiography (MRA) OR lower extremity catheter-based contrast arteriography. Each of these noninvasive and invasive anatomic assessments will identify patients with at least a 50% stenosis in the affected segment
- Stable use of low to moderate dose statin and the permitted statin drugs/doses: atorvastatin 20 mg, simvastatin 40 mg, rosuvastatin 10 mg, pravastatin, 40 mg, fluvastatin 80 mg or lovastatin 40 mg for at least 6 weeks prior to screening
- Written informed consent
Exclusion
- Critical limb ischemia or other comorbid conditions that limit walking ability (claudication must be the consistent primary exercise limitation)
- Inability to complete treadmill testing per protocol requirements
- Two treadmill tests are completed at baseline to confirm reproducibility of results; those who deviates \>25% are excluded
- Severe aorto-iliac arteries stenosis or occlusion documented by noninvasive and invasive anatomic assessments
- Allergic to DVDMS
- Diagnosis of porphyria
- Pregnant women and nursing mothers
- Contraindications of PET/CT
- Concurrent enrollment in another clinical trial
- Presence of any clinical condition that in the opinion of the principal Investigator or the sponsor makes the patient not suitable to participate in the trial
