Brief Summary

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

This is a prospective, randomized, placebo-controlled, double blind safety and feasibility clinical trial.

Detailed Description

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

To assess the safety and feasibility of Adipose-Derived Regenerative Cells (ADRCs) delivered via an intramyocardial route in the treatment of chronic ischemic heart disease in patients who are not eligible for percutaneous or surgical revascularization.

Study Groups

ADRCs processed by the Celution System

400,000 adipose-derived regenerative cells (ADRCs) per kilogram (kg) of body weight not to exceed 40,000,000 cells.

Group Type EXPERIMENTAL

ADRCs processed by the Celution System

Intervention Type DEVICE

Subjects will undergo liposuction under anesthesia. Lipoaspirate will be processed in the Celution System to isolate and concentrate ADRCs. When randomized to ADRCs, intramyocardial injections of ADRCs will be administered via the MYOSTAR injection catheter.

Lactated Ringers and Subject's blood

Sterile Lactated Ringers Solution (3mL) mixed with ≤ 0.10 ml of the study Subject's own freshly drawn blood.

Group Type PLACEBO_COMPARATOR

Placebo Comparator: Lactated Ringer's and Subject's Blood

Intervention Type DEVICE

Subjects will undergo liposuction under anesthesia. Lipoaspirate will be processed in the Celution System to isolate and concentrate ADRCs. When randomized to Placebo, intramyocardial injections of Placebo will be administered via the MYOSTAR injection catheter.
