NCT ID: NCT02059681

Last Updated: 2022-03-22

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 12 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-12-31
• Study Completion Date: 2022-02-28

Brief Summary

The purpose of this study is to evaluate whether endocavitary intramyocardial injection of autologous bone-marrow-derived CD133+ cells is safe on the basis of number of adverse events, with follow-up assessments extending up to 1 year after enrolment.

Detailed Description

This will be a Phase I study investigating the safety and preliminary efficacy of endocavitary injection of bone-marrow-derived CD133+ cells in 15 patients with ischemic heart failure (IHF) not eligible for conventional revascularization. Patients eligible will undergo bone-marrow aspiration. On the day following bone-marrow aspiration patients will undergo fluoroscopy-based endocavitary intramyocardial injections of the target areas previously identified by gated-SPECT/CMR. CD133+ cells suspended in physiological saline supplemented with 5% human albumin solution will be injected into the myocardium via the endocardial route.

After discharge, efficacy follow-up will last 6-months safety follow-up (FU) will be extended up to 1 year.

Study Groups

Autologous bone marrow derived-CD133+ cells

CD133+ cells (1-12x10\^6) suspended in 10 ml physiological saline supplemented with 5% human albumin solution will be injected into the myocardium via the endocardial route; the whole 10 ml solution will be divided into 15-20 injections.
