Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Treatment Group:

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)

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
Quadruple-blinded, placebo-controlled study. Patients, investigators, the CRO, core labs and the sponsor will be blinded for individual treatment adjudication.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CardiAMP cell therapy system

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.

Group Type ACTIVE_COMPARATOR

CardiAMP Cell Therapy System

Intervention Type DEVICE

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 procedure control

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)

Group Type SHAM_COMPARATOR

Sham Treatment

Intervention Type OTHER

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