About this study

Official title: A Randomized Optical Coherence Tomography Study Comparing Resolute Integrity to Biomatrix Drug-eluting Stent on the Degree of Early Stent Healing and Late Lumen Loss.The OCT-ORION Study

Stent coverage and neo-intimal growth can be evaluated in-detail by intracoronary optical coherence tomography (OCT), which is a catheter-based imaging technique. It is performed as part of the PCI procedure. OCT is the optical analogue of intravascular ultrasound (IVUS), except that it can provide much higher resolution of coronary cross sectional images than IVUS. The LightLab C7XR OCT system (Frequency Domain OCT) used in this Hospital has obtained full CE Mark, approved by the US FDA, and approved for clinical use in Hong Kong. It has been shown to be safe in clinical settings and has been used in over 300 patients without complication at Queen Mary Hospital.

In this study, stent coverage and neo-intimal growth between zotarolimus-eluting stents (ZES) and biolimus-eluting stents (BES) will be compared by using OCT at 9 month and specific post-intervention re-study intervals.

The investigators objective is to investigate the clinical impact and OCT difference on early stent healing and late lumen loss between the two new-generation limus-eluting-stents - Resolute Integrity and Biomatrix, which differ in stent design, eluting drug and coating polymer.

Read the detailed description

This is a prospective, randomised, assessor-blinded, single centre study. Patients with symptomatic coronary artery diseases in 2 or 3 coronary vessels requiring PCI are eligible for the study. PCI will be performed in the usual manner to all the study lesions in the same procedure. In a randomized fashion, each patient will have one artery with critical disease(s) treated by the Resolute Integrity Stent(s) and the other artery treated by the Biomatrix Stent(s).

Baseline OCT data will be obtained right after stenting. The remaining coronary artery, if diseased and required PCI treatment, will be treated during the angiographic and OCT follow-up as a staged procedure. Patients will be randomly assigned into 5 groups with equal number, receiving a follow-up coronary angiogram with OCT from 2, 3, 4, 5 and 6 months interval post-intervention. Each patient will serve as his/her own control comparing the 2 types of stents. At 9-month post-intervention, all patients will receive a second follow-up coronary angiogram with OCT. All OCT data analyses will be performed in a blinded fashion by a core laboratory. Phone follow up will be carried out for cardiac events at 1 year and 2 year of post intervention.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Resolute Integrity Stent and Biomatrix stent in people with Coronary Artery Disease, run by The University of Hong Kong at 1 site in Hong Kong.

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 2 inclusion and 14 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 26 Jul 2017. 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 Hong Kong. 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.

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?

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?

• OCT derived percentage stent strut coverage at 9 month (time frame: 9 month). 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 NCT01742507, which also lists 18 linked publications.

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 26 Jul 2017.
