Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Concentrated autologous bone marrow mononuclear cells (ABM MNC) contain potentially therapeutic cell factors and past studies support therapeutic benefit to patients with cardiac diseases of acute myocardial infarction, ischemia, and heart failure when utilized as this study is designed. The purpose of the study is to determine the safety and efficacy of CardiAMP cell therapy system in patients with ischemic heart failure. It is a prospective, multi-center, randomized, controlled, patient and evaluator-blinded study comparing treatment with the CardiAMP cell therapy system to a control procedure with diagnostic catheterization.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic heart failure is in need of new therapies. Over the past few years, cardiovascular regenerative medicine using bone marrow derived cells has emerged as a new treatment strategy that could have tremendous benefit in treating heart failure and are well supported by recent meta analyses of early clinical data sets. Concentrated autologous bone marrow mononuclear cells (ABM MNC) are the subject of the current study as they are supported by more clinical data than any other cell type described, and contain all of the potentially therapeutic cell factors from studies of selected cells. Study results demonstrate ABM MNC to be safe, and, when delivered intramyocardially as intended in the current study, results consistently support therapeutic benefit to patients with cardiac diseases of acute myocardial infarction, ischemia, and heart failure. The purpose of the study is to determine the safety and efficacy of CardiAMP cell therapy system in patients with ischemic heart failure. It is a prospective, multi-center, randomized, controlled, patient and evaluator-blinded study comparing treatment with the CardiAMP cell therapy system to a control procedure with diagnostic catheterization. The Treatment Group undergoes left ventricular catheterization and is treated with ABM MNC using the CardiAMP cell therapy system. The Control Group has a Control procedure consisting of left ventricular diagnostic catheterization but no introduction of the Helix transendocardial delivery catheter and no administration of ABM MNC.

Study (ABM MNC) Treatment

Left ventricular catheterization with treatment consisting of autologous bone marrow mononuclear cells (ABM MNC) processed and delivered using the CardiAMP cell therapy system

Group Type EXPERIMENTAL

Autologous bone marrow mononuclear cells processed / delivered using the CardiAMP cell therapy system

Intervention Type DEVICE

Control Treatment

Left ventricular (diagnostic) catheterization but no administration of ABM MNC

Group Type SHAM_COMPARATOR

Autologous bone marrow mononuclear cells processed / delivered using the CardiAMP cell therapy system

Intervention Type DEVICE

the ABM MNC is obtained from the study patient via bone marrow aspiration in the hip and processed and delivered using the CardiAMP cell therapy system during the cardiac catheterization.
