Status and phase: Withdrawn; Phase 1

Conditions: Ischemic Congestive Heart Failure

Study type: Interventional

Funder types: Industry

Identifiers

ADI-ME-CHF-002

Details and patient eligibility

About

The intent of this clinical study is to answer the questions:

1. Is the proposed treatment safe
2. Is treatment effective in improving the disease pathology of patients with Heart Disease as assessed by a series of measurements indicating improvement, stability, or degradation of a patient's cardiovascular function and exercise capacity?

Full description

This will be an open-label, non-randomized, multi-center patient-sponsored study designed to assess the safety and cardiovascular effects of Adipose-derived Stem Cell (ASC) implantation using a catheter delivery system in patients who have experienced myocardial infarction. A percutaneous transluminal endomyocardial injection catheter will be used for delivery of ASCs. The therapy is composed of cells isolated from a patient's own adipose tissue. Liposuction will be performed to collect the adipose tissue specimen for subsequent processing to isolate the stem cells.
