Study Arms (2)

OMC and pseudo-SDT

PLACEBO COMPARATOR

Optimal medical care (OMC) and pseudo-SDT are administrated in this arm. OMC is established according to the standards established by the 2017 China Guidelines for the Diagnosis and Treatment of Carotid Artery Stenosis in order to promote best practices for risk factor management. Pseudo-SDT combines saline injection and obstructed ultrasound exposure on targeted lesions to simulate real SDT progression.

OMC and SDT

EXPERIMENTAL

OMC and sonodynamic therapy (SDT) are administrated in this arm.

Combination Product: Sonodynamic therapy (SDT)

Interventions

Sonodynamic therapy (SDT)COMBINATION_PRODUCT

Sonodynamic therapy(SDT) treatment is the combination of sonosensitizer administration and target atherosclerotic lesions ultrasound exposure. Sinoporphyrin sodium (DVDMS) as sonosensitizer, is dissolved in 0.9% sodium solution for following skin test and intravenous injection. 0.01mg/ml DVDMS solution (0.1ml) is prepared for skin test followed by 0.04 mg/ml DVDMS solution intravenous injection (0.2mg/kg).The target atherosclerotic lesions are marked on the corresponding skin with ultrasound guidance and underwent ultrasound exposure after 4 hours incubation. The therapeutic ultrasonic transducer is fixed to the marked skin site for 15min of each lesion. Ultrasound parameters included intensity of 1.6W/cm2 for carotid lesions, resonance frequency: 1.0 MHz and duty factor: 30%.

  • Contraindication to MRI( uses pacemaker, has metallic implants, claustrophobia)
  • Acute MI, acute coronary syndrome or stroke within 4 weeks prior to visit or during run-in
  • Severe cerebral artery stenosis, atrial fibrillation or MRI detected thrombosis that would cause stroke
  • Previous significant adverse reaction to a statin
  • Systemic disorders such as hepatic, renal, hematologic, and malignant disease
  • Medical history that might limit the individual's ability to take trial treatments for the duration of the study
  • Allergic to DVDMS or sonovue
