Prospective Randomized Endovascular Therapy in Multiple Sclerosis (PREMiSe)

August 5, 2025 updated by: Adnan H. Siddiqui, University at Buffalo
  1. To assess the safety of endovascular therapy (balloon angioplasty) for venous stenoses in MS patients with CCSVI as documented by sonographic (extracranial echocolor-Doppler (ECD) and transcranial color Doppler (TCD)
  2. To study the morphology of the venous anomalies by using intraluminal ultrasound (IVUS).
  3. To evaluate preliminary efficacy of endovascular therapy (angioplasty) as measured by clinical (relapse rate, disability progression (EDSS)), sonographic (ECD/TCD) and MRI/MRV parameters.
  4. To evaluate change in patients self-reported QOL following the therapeutic angioplasty
  5. To evaluate whether changes in QOL, fatigue, MSFC or attention following therapeutic angioplasty are associated with brain changes as measured by functional MRI (fMRI).

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Venous Angioplasty
20 patients will have venous angio plasty
venous angiogram to look for lesions or flaps and then plastying vessels open.
Sham Comparator: Angio with no plasty
Patients will be brought to the angio suite and given and angio but no plasty although patient will not be aware of which treatment they are having.
Patients will be brought to the angio suite and will not know if they are having the venous angioplasty or not.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Patients With Immediate and Short-term SAE
Time Frame: 1 month post-procedure
Percent (%) of patients with Severe Adverse Events (SAE) measured at 1 month (Short term) post-surgical safety outcome in MS patients diagnosed with CCSVI that underwent therapeutic angioplasty. The 95% confidence interval of the SAE rates for immediate and short terms will be obtained by the exact method, respectively. The immediate and short term SAE rates will be analyzed, respectively, using the Fisher's exact test.
1 month post-procedure
