Prospective, multi-center, 2:1 randomized (Treatment : Sham Control), sham-controlled, double-blinded trial to compare treatment using the CardiAMP cell therapy system to sham treatment
Subjects treated with aBMC using the CardiAMP cell therapy system
Sham Control Group:
Subjects treated with a Sham Treatment (no introduction of the Helix transendocardial delivery catheter, no administration of aBMC)

Active Comparator: CardiAMP cell therapy system
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
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.
Sham Comparator: Sham procedure control
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
Patients will receive sham bone marrow procedure and a ventriculogram. A scripted sham percutaneous procedure will be performed
- Change from Baseline in Total Exercise Time on the treadmill using the Modified Bruce Protocol [ Time Frame: Baseline and 12 months visit ]A superiority analysis with regards to change from Baseline in Total Exercise Time at the 12 months follow-up visit (using a Modified Bruce Protocol).
- Safety: overall survival at 12 months follow-up [ Time Frame: at 12 months follow-up ]A non-inferiority analysis of overall survival at 12-months will be made comparing the Treatment group to the Sham Control group using a non-inferiority margin of 10%.
- Safety: Total Major adverse cardiac events (MACE) at 12 months follow-up [ Time Frame: from randomisation to 12 months follow-up ]A non-inferiority analysis with regard to Total Major Adverse Cardiac Events (MACE: defined as death, cardiac hospitalization, non-fatal myocardial infarction and stroke) at 12 month follow-up, as adjudicated by an independent clinical endpoint classification (CEC) committee with 10% margin.
- Efficacy: Change from baseline in Total Exercise Time at 6 months follow-up [ Time Frame: Baseline and at 6 months follow-up ]Superiority analysis with regards to change from baseline in Total Exercise Time on Exercise Tolerance Test (ETT) at 6 Month Follow-up Visit. Baseline (BL) is the average of (at least) two total exercise times measured during the screening period.
- Efficacy: Change of angina frequency (per week) at 12 months follow-up [ Time Frame: Baseline and at 12 months follow-up ]
Superiority analysis with regards to change in angina frequency (episodes per week) at 12 month follow-up Visit versus baseline angina frequency (per week).
Participants self-reported angina episodes utilizing an electronic diary for 4 weeks at baseline (screening period) and in the 4 weeks before the 12-month follow-up visits.
- Efficacy: Change of Angina Frequency (per week) at 6 months follow-up [ Time Frame: Baseline and at 6 months follow-up ]
Superiority analysis with regards to change in angina frequency at 6 month follow-up visit versus baseline (expressed as angina frequency per week).
Participants self-reported angina episodes utilizing an electronic diary for 4 weeks at baseline and in the 4 weeks before the 6-month follow-up visits.
- Safety: Total Major adverse cardiac events (MACE) at 24 months follow-up [ Time Frame: From randomisation to 24 month follow-up ]Superiority analysis with regards to incidence of MACE from Randomization until the end of the 24 month follow-up period
- Efficacy: Percentage of patients with at least 1 Serious Adverse Event (SAE) [ Time Frame: From randomization to 24 Months follow-up ]Superiority analysis with regards to percentage of participants with at least one SAE. From randomization until the end of the 24 month follow-up period.
