About this study
Official title: Safety and Efficacy of Transendocardial Injection of Autologous Endothelial Progenitor Cell CD 133 for Therapeutics Angiogenesis
The purpose of this study is to determine whether transendocardial injections of autologous endothelial progenitor cells CD 133 is safe and feasible in patients with refractory angina.
Read the detailed description
The PROGENITOR trial is a randomized, double-blinded, multicenter controlled trial including patients with Canadian cardiovascular society angina classification (CCS): II-IV and ischemic zones by SPECT but without any option for revascularization. Primary endpoint was to assess the safety and feasibility of transendocardial injection of selected CD133+cells. All patients were treated for 4-days with granulocyte colony-stimulating factor and underwent apheresis. CD133+ cells were selected with CliniMacs system and were injected transendocardially guided by the NOGA XP system.

What is being measured
The primary outcome is the main question the study is designed to answer.
major adverse cardiac and cerebrovascular event
cardiovascular death, non-fatal myocardial infarction (MI), ischemic stroke, need for revascularization or , procedure-related complications (: pericardial effusion/cardiac tamponade, vascular complications and sustained ventricular arrhythmias).
Measured: 6, 12 and 24 months
Secondary outcomes (1)
Efficacy
The change in the myocardial perfusion defect at baseline versus follow-up measured by Single Photon Emission Computed Tomography (SPECT). Treadmill test, and clinical evaluation (CCS, nº angina episodes/month, nº nitroglycerin /month, Quality of life by seattle questionnaire)
Measured: 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Selected CD 133+ cells in people with Coronary Artery Disease and Refractory Angina, run by Pilar Jimenez Quevedo at 1 site in Spain.
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 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: finished, as of the sponsor's last update on 6 Aug 2013. 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 Spain. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
major adverse cardiac and cerebrovascular event (time frame: 6, 12 and 24 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 6 Aug 2013; AzTrials last refreshed its copy on 8 Nov 2026.
