About this study

Use of SeQuent® Please drug coated balloon (DCB) is effective to treat patients with in-stent restenosis (ISR). However, whether the type of pre-dilatation balloon prior to DCB dilatation impacts on clinical and angiographic outcomes or not is unknown. Lacrosse® Non-slip element balloon (NSE) is a balloon catheter with 3 longitudinal plastic elements which are attached to proximal and distal balloon edges. NSE is developed to incise neointimal tissue and avoid balloon slippage without vitiating balloon derivability and crossability. We investigated angiographic and clinical outcomes following normal non-compliant balloon or NSE dilatation prior to DCB dilatation in ISR lesions.This study is a single blinded, multicenter, randomized trial. Total 200 patients with ISR are randomly assigned to treat with non-compliant balloon or NSE before DCB dilatation. Optical coherence tomographic (OCT) analysis are performed before pre-dilatation and after DCB dilatation Follow-up angiography analysis are planned at 8 months in all patients. Clinical follow-up is planned at 8 and 24 months.Primary endpoint is angiographic in-segment late loss at 8 months.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Non-slip element balloon (NSE) and Balloon in people with Coronary Restenosis, run by Mitsui Memorial Hospital at 2 sites in Japan.

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 1 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 23 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Japan. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Angiographic in-segment late loss (time frame: 8 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02300454, which also lists 1 linked publication.

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 23 Mar 2017.
