Safety Study of Transmyocardial Revascularization (TMR) With Bone Marrow Aspirate (BMAC) for Angina Reduction (PHOENIX)

August 18, 2015 updated by: Cardiogenesis Corporation, a wholly-owned subsidiary of CryoLife, Inc.

A Prospective, Multicenter, Single Arm Study of Transmyocardial Revascularization (TMR) Plus Bone Marrow Aspirate Concentrated (BMAC) Using the Cardiogenesis PHOENIX Combination Handpiece Delivery System

The purpose of this study is to determine the safety of injecting autologous bone marrow concentrate with laser transmyocardial revascularization (TMR) for treatment of angina which cannot be treated by direct coronary intervention.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Recently published information suggests the delivery of concentrated autologous bone marrow, in combination with transmyocardial revascularization (TMR) may provide synergistic effects for the reduction of angina in patients who are not treatable with conventional coronary artery bypass or percutaneous coronary intervention. This safety and feasibility study is intended to confirm the work previously done at one hospital in a larger, multicenter setting. Patients who are candidates for TMR will be asked to participate.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Adult patient, 18 years of age or older, male or female.
  • Left ventricular ejection fraction greater than or equal to 40% (documented within 6 months of the TMR procedure.
  • Patient with medically refractory, stable, Class IV angina according to the Canadian Cardiovascular Society angina scale. Optimal medical therapy is defined as maximum tolerable and stable doses of beta-blockers, statins, anti-platelets and long acting nitrates without control of symptoms for at least 30 days.
  • Patient with at least a 15 cm² (or 15% of the surface area in the distal 2/3 of the left ventricle free wall to allow for a minimum of 15 TMR channels) documented region of the myocardium in the distal two-thirds of the left ventricle with reversible ischemia. Patients will be enrolled based on images used to determine eligibility for TMR within the previous 6 months. However, all patients will have baseline and follow-up MRIs taken per a standardized protocol and adjudicated by a core lab.
  • Has a documented left ventricular wall thickness of ≥8 mm.
  • Patient is not a candidate for treatment by direct coronary revascularization methods (i.e., CABG or PCI) as documented by an independent interventional cardiologist and an independent cardiothoracic surgeon on the Angiographic Screening Form.
  • Patient is able to perform the baseline exercise tolerance test (ETT).
  • Patient, if female, has no childbearing potential or has had a negative urine or serum pregnancy test within 7 days of the procedure.
  • Patient has a bone marrow aspirate total nucleated count of at least 15 x 106/mL at the time of harvest.
  • Patient has provided informed consent.

Exclusion Criteria:

  • Cannot undergo a surgical procedure, thoracotomy or general anesthesia.
  • Has any mechanical or prosthetic heart valve.
  • Has a history of bone marrow disease (especially Non-Hodgkin's Lymphoma and Myelodysplastic Syndrome) that prohibits autologous bone marrow derived cell transplantation.
  • Has severe, new onset or increasing angina. In addition, patients who cannot be weaned from intravenous anti-anginal medications for at least 48 hours preoperatively are to be excluded. Severe, new onset and increasing angina is defined as: Severe angina - angina occurring at rest and usually prolonged >20 minutes occurring within a week of presentation; new onset angina - angina of at least Canadian Cardiovascular Society Classification (CCSC) III severity with onset within 2 months of initial presentation; and increasing angina - previously diagnosed angina that is distinctly more frequent, longer in duration, or lower in threshold, (i.e., increased by at least one CCSC class within 2 months of initial presentation to at least CCSC III severity.
  • Has had a STEMI (ST Elevation Myocardial Infarction) or NSTEMI (Non-STEMI) within 4 weeks of the TMR procedure.
  • Has decompensated heart failure, or a diagnosis of NYHA Functional Class III/IV heart failure.
  • Has a hemorrhagic propensity that cannot be addressed with drug management.
  • Has severe or life-threatening arrhythmia (e.g., ventricular tachycardia or fibrillation) within one week prior to the TMR procedure.
  • Is unable to undergo a cardiac MRI procedure.
  • Has uncontrolled diabetes with HbA1C > 10%.
  • Has anemia defined as hematocrit < 33% in women and <39% in men.
  • Has moderate to severe renal dysfunction defined as serum creatinine >1.8 mg/dL.
  • Has moderate to severe liver dysfunction defined as> ALT/AST >5X the upper limit of normal.
  • Is unable or unwilling to return for follow-up.
  • Is participating in another clinical investigation within the prior 30 days.
