About this study

Official title: Evaluation of Vascular Regeneration After a Drug Eluting Stent Implantation and the Development of Neointimal Hyperplasia and Stent Restenosis (REVER Trial).

This is a prospective cohort, one center. twenty patients who will undergo percutaneous stent implantation with everolimus eluting stent will be include. The primary endpoint was the correlation between the change (baseline vs. 1 week) in the number of circulating endothelial progenitor cells and in cell functionality following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence tomography

Read the detailed description

For the purpose of the study, flow cytometry analyses will be performed before intervention, at 1 week, 1 month and 9 months. In addition, cell functionality analyses will be performed by quantification of colony forming units, aldehidrodehidrogenase activity, cell proliferation by WST-1 and senescence by !-galactosidase enzyme. At 9 months the degree of neointimal proliferation will be measured by optical coherence tomography . A clinical follow-up will be performed at 1 year. Secondary endpoints include: 1. to correlate the change in the number and cell functionality of circulation progenitor cells following everolimus eluting stent and the injury score analyses measured by optical coherence tomography, and the percentage of non covered struts by optical coherence tomography at 9 months.

2.-. To evaluate the role of other subtypes of cells CD 133+/Kinase Insert Domain Receptor (KDR+), CD 14+, mesenchymal stem cells, endothelial cell markers (VE cadherina, P1H12), integrin expression of Macrophage-1 antigen (MAC-1) and the development of neointimal hyperplasia.

What is being measured

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

  1. The correlation between the change (baseline vs 1 week) of circulating with neointimal hyperplasia endothelial progenitor cells and in cell functionality following an Everolimus eluting stent implantation with the grade of neointimal hyperplasia

    Correlation between the change (baseline vs 1 week) in the number of circulating endothelial progenitor cells and in cell functionality following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence Tomography

    Measured: 9 months

Secondary outcomes (5)
  1. to correlate number of cell and functionality of progenitor cells and injury score following everolimus eluting stent

    to correlate the number and cell functionality of progenitor cells following everolimus eluting stent and the injury score analyses measured by optical coherence tomography

    Measured: baseline

  2. to evaluate other subtypes of cells with neointimal hyperplasia

    To evaluate the role of other subtypes of cells CD 133+/KDR+, following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence Tomography

    Measured: 9 months

  3. to evaluate other subtypes of cells with neointimal hyperplasia

    the role of other subtypes of cells CD 14+ following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence Tomography

    Measured: 9 months

  4. to evaluate endothelial cell markers with neointimal hyperplasia

    the role of endothelial cell markers (VE cadherin, P1H12) following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence Tomography

    Measured: 9 months

  5. to evaluate integrin expression of MAC-1 (Macrophage-1 antigen) with neointimal hyperplasia

    the role of integrin expression of MAC-1(Macrophage-1 antigen) following an everolimus eluting stent implantation with the grade of neointimal hyperplasia measured by optical coherence Tomography

    Measured: 9 months

Questions about this trial

What is this clinical trial studying?

An observational study of Stable Angina, run by Hospital San Carlos, Madrid.

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 3 inclusion and 12 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 18 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

The correlation between the change (baseline vs 1 week) of circulating with neointimal hyperplasia endothelial progenitor cells and in cell functionality following an Everolimus eluting stent implantation with the grade of neointimal hyperplasia (time frame: 9 months). 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 18 Jul 2017.
