About this study

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

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.

Read the 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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. rate of in-stent restenosis

    DSA angiography performed after 6 months (± 30 days) showed the occurrence of in-stent restenosis and the restenosis rate ≥ 50%;

    Measured: 6 months (± 30 days) after procedure

Secondary outcomes (3)
  1. Immediate stent implantation success rate

    postoperative angiography immediately after implantation of Firehorus indicated that residual stenosis ≤ 20% (the degree of stenosis is determined according to the WASID method)

    Measured: Immediate after the procedure

  2. Any death or stroke related to the treated area

    Any death or stroke related to the treated area supplied by the target blood vessels during the follow-up period.

    Measured: 1 year

  3. Any death or stroke

    Any death or stroke during the follow-up period

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Drug-eluting stent in people with Vertebrobasilar Insufficiency, run by Zhongrong Miao at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

rate of in-stent restenosis (time frame: 6 months (± 30 days) after procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2020.
