  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age 18 and older;

Show all 13Show fewer
  • Any significant medical condition which in the Investigator's opinion may interfere with the patient's optimal participation in the study;

About this study

Official title: Prospective, Multi-centre, Randomized, Parallel Comparison to Evaluate the Safety and Efficacy of the Abluminal Sirolimus Coated Bio-engineered Stent (COMBO Stent) in Association With Short-term Single Antiplatelet Therapy in Patients With Coronary Artery Disease With an Indication for Chronic Oral Anticoagulant Therapy as Compared to a Guidelines-based Strategy

Prospective, multi-centre, randomized, open-label, parallel comparisons to evaluate

  • the incidence of bleedings (COSTA-Bleed) and
  • the incidence of ischemic and bleeding events (COSTA-Outcome) following a therapy with the abluminal sirolimus coated bio-engineered stent (COMBO stent) in association with short-term single antiplatelet therapy as compared to a guidelines-based strategy in patients with coronary artery disease with an indication for chronic oral anticoagulant therapy.
Read the detailed description

The COSTA trials are investigator-initiated studies aimed at comparing the clinical outcome after percutaneous coronary intervention (PCI) using a COMBO-stent based strategy associated with short-term antiplatelet therapy with a guidelines-based therapy in patients with an indication for chronic oral anticoagulation. The study is organized as a national, multi-centre prospective, randomized trial. The duration of the follow-up is 15 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • COMBO-StentDevice

    The OrbusNeich COMBO Bio-engineered Sirolimus Eluting Stent (COMBO Stent) consists of a 316L stainless steel alloy abluminally coated with a biocompatible, biodegradable poly-mer containing sirolimus. Covalently attached to the surface of the stent is a layer of murine, monoclonal, anti-human CD34 antibody. The antibody specifically targets circulatory CD34+ cells (endothelial progenitor cells) thus favoring endothelialization.

    Also called Plavix, Marcumar, Xarelto, Pradaxa

    Anticoagulant medication after stent Implantation: (N)OAC and clopidogrel for 3 months followed by (N)OAC

What is being measured

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

  1. Number of patients with bleedings

    any BARC (bleeding academic research consortium) bleeding at 6 weeks - superiority.

    Measured: 6 weeks

  2. Number of patients with safety events

    Strategy oriented composite safety endpoint, including death (unless proven not to be connected to the other endpoints), any MI, stroke or systemic embolism, definite or probable stent thrombosis, BARC 3-4 bleeding at 15 months post PCI - non-inferiority with reflex to superiority testing. Hierarchical testing: Endpoint II is only tested if null hypothesis of no difference in bleeding incidence can be rejected at final analysis.

    Measured: 15 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing COMBO-Stent, Clopidogrel, Vitamin K Antagonist, Rivaroxaban, Dabigatran and Any drug eluting stent oder bare metal sent in people with Stable Angina and Unstable Angina, run by IHF GmbH - Institut für Herzinfarktforschung at 10 sites in Germany.

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 4 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: withdrawn, as of the sponsor's last update on 20 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Germany. 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 was withdrawn before enrolling participants, so there are no results.

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?

Number of patients with bleedings (time frame: 6 weeks). The study lists 2 primary outcomes in all. 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 20 Feb 2017.
