A Randomized Clinical Trial of Adipose-derived Stem Cells in Treatment of Non Revascularizable Ischemic Myocardium

This study has been completed.
Information provided by (Responsible Party):
Cytori Therapeutics Identifier:
First received: January 23, 2007
Last updated: August 27, 2013
Last verified: August 2013
The purpose of this study is to establish safety and feasibility of utilizing Adipose Derived Stem & Regenerative Cells (ADRCs) in patients who have areas of myocardium that are not revascularizable and have demonstrated reversible ischemia.

Condition Intervention Phase
Ischemic Heart Disease
Coronary Arteriosclerosis
Cardiovascular Disease
Coronary Disease
Coronary Artery Disease
Other: Direct injection of ADRCs into the Left Ventricle
Other: Direct injection of placebo into the Left Ventricle
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Clinical Trial of adiPose-deRived stEm & Regenerative Cells In the Treatment of Patients With Non revaScularizable ischEmic Myocardium - The PRECISE Trial

Further study details as provided by Cytori Therapeutics:

Primary Outcome Measures:
  • Safety - Determined by Major Adverse Cardiac and Cerebral Events (MACCE) [ Time Frame: Up to 36 months ]

Secondary Outcome Measures:
  • Feasibility - Assessment of cardiac function using a variety of functional and imaging studies including MRI, SPECT and Echocardiography [ Time Frame: Up to 36 months ]

Enrollment: 27
Study Start Date: January 2007
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment Other: Direct injection of ADRCs into the Left Ventricle
Dose escalation
Placebo Comparator: Placebo Other: Direct injection of placebo into the Left Ventricle

Detailed Description:

Subjects who have coronary artery disease that cannot be revascularized and demonstrate reversible ischemia in the area supplied by the non-revascularizable vessel(s) will be evaluated for eligibility in this study. Eligible subjects will undergo standard pre-operative testing after admission to the hospital, and then will undergo liposuction under anesthesia, after which ADRCs will be isolated from the lipoaspirate. According to randomization subjects will receive either ADRCs or placebo.

The outcomes of this trial will be based on assessment of primary and secondary endpoints at 6 months post index procedure. Long Term Follow-up will be conducted at 12, 18, 24 and 36 months after the procedure.


Ages Eligible for Study:   20 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Able to provide written informed consent
  • Males or females 20 to 75 years of age, inclusive
  • Coronary artery disease not amenable to any type of revascularization procedure (percutaneous or surgical) in the target area
  • Hemodynamic stability
  • Ability to undergo liposuction
  • Ability to walk on a treadmill
  • Negative urine pregnancy test (females only).

Key Exclusion Criteria:

  • Unstable angina
  • Serum creatinine >2.5 mg/dL
  • Planned or scheduled staged treatment of CAD or other interventional or surgical procedures
  • Cardiogenic shock
  • History of resuscitated sudden cardiac death; or symptomatic or sustained ventricular fibrillation or ventricular tachycardia.
  • Vascular anatomy that precludes cardiac catheterization
  • Peripheral artery disease that precludes insertion of an 8 Fr sheath
  • Severe valvular disease
  • Pregnant or nursing females
  • Known and relevant allergies or sensitivities
  • Life expectancy <1 year
  • Participation in any other clinical research study that has not reached its primary endpoint or otherwise would interfere with the subject's participation in this study
  • Any concurrent disease or condition that, in the opinion of the investigator, would make the subject unsuitable for participation in the study.
