Prospective Evaluation of Safety and Efficacy Vertebral Drug-eluting Stent System (PESS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02328781
Recruitment Status : Completed

Brief Summary:
The purpose of this study is to evaluate the safety and efficacy of Firehorus vertebral artery rapamycin-target-eluting stent system (hereinafter referred to as Firehorus) in treatment of symptomatic vertebral artery stenosis.

Condition or disease Intervention/treatment Phase
Vertebrobasilar Insufficiency Device: Drug-eluting stent Not Applicable

Detailed Description:
This clinical trial utilizes the prospective, multicenter, single-arm target value trial design, to evaluate the safety and efficacy of Firehorus vertebral artery rapamycin-target-eluting stent system (hereinafter referred to as Firehorus) in clinical use, for which 5 (or more) institutions will be selected as Clinical Trial Centre.Subjects will be screened in accordance with the inclusion and exclusion criteria of the this protocol and will be treated with Firehorus. Immediate stent implantation success rate of all subjects after surgery will be recorded, DSA angiographic follow-up will be performed at six months (±30 days) after surgery to assess the incidence of stent restenosis ( stenosis ≥ 50%) of the subjects, and the subjects will be followed up at 30 days (±7 days), 6 months (± 30 days), 12 months (± 30 days) after surgery , so as to evaluate the safety and efficacy of Firehorus in clinical use. The expected participating duration of each subject from enrollment to complete the follow-up is 12 months (± 30 days).

Primary Purpose: Treatment
Official Title: Prospective Multi-center Single-arm Target Value Clinical Trial for Evaluating Clinical Use Safety and Efficacy of the Firehorus Vertebral Artery Rapamycin-target-eluting Stent System
Actual Study Start Date : July 17, 2014
Actual Primary Completion Date : June 14, 2016
Actual Study Completion Date : November 25, 2016

Arm Intervention/treatment
Experimental: Experimental
Drug-eluting stent
Device: Drug-eluting stent

Primary Outcome Measures :
  1. rate of in-stent restenosis [ Time Frame: 6 months (± 30 days) after procedure ]
    DSA angiography performed after 6 months (± 30 days) showed the occurrence of in-stent restenosis and the restenosis rate ≥ 50%;

Secondary Outcome Measures :
  1. Immediate stent implantation success rate [ Time Frame: Immediate after the procedure ]
    postoperative angiography immediately after implantation of Firehorus indicated that residual stenosis ≤ 20% (the degree of stenosis is determined according to the WASID method)

  2. Any death or stroke related to the treated area [ Time Frame: 1 year ]
    Any death or stroke related to the treated area supplied by the target blood vessels during the follow-up period.

  3. Any death or stroke [ Time Frame: 1 year ]
    Any death or stroke during the follow-up period

  2. Patients with symptomatic vertebral artery stenosis not responding to drug therapy (defined as stroke or TIA occurred within 90 days, the patient is using at least one antithrombotic drug and receiving interventions for other vascular risk factors, such as antihypertensive therapy or lipid-lowering therapy for hypertensionor high cholesterol when stroke or TIA occurs)
  3. DSA angiography indicated target lesion stenosis ≥ 50% (the degree of stenosis is determined according to the WASID method)
  4. Length of vascular lesion ≤ 21mm
  5. Modified Rankin score < 3
  6. Suiform for placing with vertebral artery rapamycin-eluting stent, voluntary to receive follow-up and sing the informed consent

Exclusion Criteria:

  1. There is a series of stenosis lesion within the target lesion region
  2. TIA or non- disabling stroke (such as atrial fibrillation, etc.) caused by other factors other than vertebral artery stenosis
