Outcome Measures

Primary Outcomes (1)

  • Change from Baseline in Total Exercise Time on the treadmill using the Modified Bruce Protocol

    A superiority analysis with regards to change from Baseline in Total Exercise Time at the 6 months follow-up visit (using a Modified Bruce Protocol).

    Baseline and 6 months visit

Secondary Outcomes (7)

  • Safety: overall survival at 6 months follow-up

    at 6 months follow-up

  • Safety: Total Major adverse cardiac events (MACE) at 6 months follow-up

    from randomisation to 6 months follow-up

  • Efficacy: Change from baseline in Total Exercise Time at 6 months follow-up

    Baseline and at 6 months follow-up

Study Arms (2)

CardiAMP cell therapy system

ACTIVE COMPARATOR

Roll-in phase: Up to 10 subjects with refractory chronic myocardial ischemia CCS class III-IV will be treated in an unblinded, uncontrolled roll-in phase. In the subsequent randomized phase: Up to 333 subjects with refractory chronic myocardial ischemia CCS class III-IV will be randomized. Up to 222 Subjects will be randomized to treatment with the CardiAMP cell therapy system.

Device: CardiAMP Cell Therapy System

Sham procedure control

SHAM COMPARATOR

Randomized phase: Up to 333 subjects with refractory chronic myocardial ischemia CCS class III-IV will be randomized. Up to 111 subjects will be treated with a Sham Treatment (no introduction of trans endocardial delivery catheter and no administration of autologous cells)

Other: Sham Treatment

Interventions

The CardiAMP Cell Therapy system consists of the CardiAMP Potency Assay, the Helix/Morph intramyocardial delivery catheter system, and the CardiAMP Cell Separator. The system allows the investigator to identify patients with a high chance to respond to im autologous stem cell therapy (using the CardiAMP Cell Potency Assay), to isolate the stem cells from a bone marrow harvest at the point of care (using the CardiAMP CS system), and to percutaneously inject the autologous cells into the myocardium using the Helix/Morph delivery catheters.

CardiAMP cell therapy system

Patients will receive sham bone marrow procedure and a ventriculogram. A scripted sham percutaneous procedure will be performed

Sham procedure control

Eligibility Criteria

Age21 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female 21 to 80 years of age
  • Canadian Cardiovascular Society (CCS) class III or IV chronic refractory angina.
  • Lack of control of angina symptoms despite maximum tolerated doses of anti-angina drugs.
  • Evidence of inducible myocardial ischemia on baseline stress testing
  • Obstructive coronary disease unsuitable for conventional revascularization
  • Experience angina episodes at a minimum of 7 angina episodes per week (during a 4-week screening period).
  • Able to complete an exercise tolerance test on the treadmill
  • Left ventricular ejection fraction of greater than or equal to 40% as measured by echocardiography.
  • Qualification of a pre-procedure screening of bone-marrow aspiration

You may not qualify if:

  • Other cardiac or vascular system or other health-related criteria which may be seen in a patient's history and physical examination.
