About this study
Official title: Study on the Safety and Efficacy of Allogeneic Mesenchymal Stem Cell Implantation Combined With Bypass Grafting in Patients With Coronary Artery Disease and Ischemic Cardiomyopathy.
The aim of the present study is to investigate safety and efficacy of intramyocardial implantation of a novel mesenchymal precursor cell type (iMP) in patients with ischemic cardiomyopathy at the time of coronary artery bypass grafting.
Read the detailed description
This study aims to investigates in situ cardiac regeneration utilizing precision delivery of a novel mesenchymal precursor cell type (iMP) during coronary artery bypass surgery (CABG) in patients with ischemic cardiomyopathy (LVEF < 40 %). Preoperative scintigraphy imaging (SPECT) will be used to identify hibernating myocardium not suitable for conventional myocardial revascularization for iMP implantation. iMP cells will be implanted intramyocardially in predefined viable peri-infarct areas that show poor perfusion, which could not be grafted due to poor target vessel quality. Postoperatively, SPECT will be used to identify changes in scar area.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Intramyocardial implantation of of a novel mesenchymal precursor cell type (iMP). in people with Coronary Artery Disease and Ischemic Cardiomyopathy, run by AHEPA University Hospital at 1 site in Greece.
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 8 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 7 May 2019. 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 Greece. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
iMP-related adverse events (time frame: 12 months). 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?
On the ClinicalTrials.gov record for NCT01753440, which also lists 3 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 7 May 2019.
