Study Details

Study Description

Brief Summary

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

Condition or Disease Intervention/Treatment Phase
  • Device: ADRCs processed by the Celution System
  • Device: Placebo Comparator: Lactated Ringer's and Subject's Blood
Phase 2

Detailed Description

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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 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.

Device: ADRCs processed by the Celution System
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.
Other Names:
  • ADRCs
  • Intramyocardial injections
  • Placebo Comparator: 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.

    Device: Placebo Comparator: Lactated Ringer's and Subject's Blood
    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.
    Other Names:
  • Placebo
  • Outcome Measures

    Primary Outcome Measures

    1. Treatment emergent serious adverse events (SAEs), major adverse cardiac events (MACE), arrhythmia assessment, change in cardiac function and symptoms, and resource utilization [6 and 12 Months]

      Safety endpoints include: Treatment emergent SAEs Arrhythmia assessment via Holter monitoring MACE defined as cardiac death and hospitalization for heart failure Feasibility endpoints include: Change in mVO2 at 6 months Change in LVESV/LVEDV at 6 months Change in ejection fraction at 6 months Change in perfusion defect at 6 months Resource utilization Change in heart failure symptoms, angina, and quality of life through 12 months
