Safety and Feasibility Trial of Adipose-Derived Regenerative Cells in the Treatment of Chronic Myocardial Ischemia

Phase 2
Completed
Conditions
Myocardial Ischemia
Interventions
Device: ADRCs processed by the Celution System
Registration Number
NCT01556022
Lead Sponsor
Cytori Therapeutics
Brief Summary

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

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.

Inclusion Criteria
  1. Males or females 20-80 years of age
  2. Significant multi-vessel coronary artery disease not amenable to percutaneous or surgical revascularization in the target area
  3. CCS Angina Functional Class II-IV and/or NYHA Stages of Heart Failure Class II or III
  4. On maximal medical therapy for anginal symptoms and or heart failure symptoms
  5. Hemodynamic stability (Systolic Blood Pressure ≥ 90 mm/Hg, Heart Rate < 110; Pulse-Oxygen > 95)
  6. Ejection fraction ≤ 45
  7. Left ventricular wall thickness ≥ 8 mm at the target site for cell injection, confirmed by 2D contrast echo within 4 weeks prior to enrollment, free of thrombus

Key

Exclusion Criteria
  1. Atrial fibrillation or flutter without a pace maker that guarantees a stable heart rate
  2. Unstable angina
  3. LV thrombus, as documented by echocardiography
  4. Planned staged treatment of CAD or other intervention on the heart
  5. Platelet count < 100,000/mm3

  7. TIA or stroke within 90 days prior to randomization
  8. ICD shock within 30 days of randomization
  9. Any condition requiring immunosuppressive medication
  10. A high-risk acute coronary syndrome (ACS) or a myocardial infarction within 60 days prior to randomization
  11. Revascularization within 60 days prior to randomization
  12. Inability to walk on a treadmill except for class IV angina patients who will be evaluated separately
  13. Hepatic dysfunction, as defined as aspartate aminotransferase (AST) and /or alanine aminotransferase (ALT) > 1.5 times the upper limit of normal range (x ULN) prior to randomization

Primary Outcome Measures
NameTimeMethod
Treatment emergent serious adverse events (SAEs), major adverse cardiac events (MACE), arrhythmia assessment, change in cardiac function and symptoms, and resource utilization6 and 12 Months

Safety endpoints include:

1. Treatment emergent SAEs

2. Arrhythmia assessment via Holter monitoring

3. MACE defined as cardiac death and hospitalization for heart failure

Feasibility endpoints include:

1. Change in mVO2 at 6 months

2. Change in LVESV/LVEDV at 6 months

3. Change in ejection fraction at 6 months

4. Change in perfusion defect at 6 months

5. Resource utilization

6. Change in heart failure symptoms, angina, and quality of life through 12 months
