About this trial
This is an interventional treatment trial for Dilated Cardiomyopathy (DCM) focused on measuring cardiomyopathy, cardiosphere-derived stem cells, intracoronary infusion, adult stem cells, heart disease, ventricular dysfunction, pathological processes, cardiovascular diseases, heart failure
Eligibility Criteria
Major Inclusion Criteria:

- Coronary anatomy suitable for Investigational Product (IP) infusion, as determined by the Eligibility Committee (a team of cardiology experts)
- Ability to provide informed consent and follow-up with protocol procedures
- Screening cardiac CT left ventriculogram ejection fraction <40% with left ventricular dilatation
- Age ≥ 18 years
Major Exclusion Criteria:

- Immunologic incompatibility with all available Master Cell Banks (MCBs) by single-antigen bead (SAB) serum antibody profiling
- Left Ventricular Assist Devices (LVAD) or those actively in the process of acquiring one
- Recent placement of a cardiac pacemaker and/or resynchronization pacing therapy within the past three months or those actively in the process of acquiring one

- Active allergic reactions, connective tissue disease or autoimmune disorders
- History of cardiac tumor, or cardiac tumor demonstrated on screening
- History of previous stem cell therapy
- History of treatment with immunosuppressive agents, including chronic systemic corticosteroids, biologic agents targeting the immune system, anti-tumor and anti-neoplastic drugs or anti-vascular endothelial growth factor (VEGF) within 6 months prior to enrollment (not including drug eluting coronary stents)

- Known history of Human Immunodeficiency Virus (HIV) infection
- Known history of chronic viral hepatitis
- Abnormal liver function (serum glutamic pyruvic transaminase (SGPT) > 10 times the upper reference range) and/or abnormal hematology (hematocrit < 25%, white blood cells (WBC) < 3000 µl, platelets < 100,000 µl) studies without a reversible, identifiable cause
- Evidence of tumor on screening of chest/abdominal/pelvic (body) CT scan
- Any prior organ transplant
- Being actively listed for, or under active consideration (i.e., work-up) for, a solid organ transplant of any kind
- Known hypersensitivity to bovine products

- Any malignancy within past 2 years (except for in-situ non-melanoma skin cancer and in-situ cervical cancer)
- Any prior radiation therapy/treatment to the chest
- Uncontrolled diabetes (HbA1 >9.0)
- Any condition or other reason that, in the opinion of the Investigator or Medical Monitor, would render the subject unsuitable for the study

Arm 2
Experimental
Placebo Comparator
Allogeneic Cardiosphere-Derived Cells
Placebo
The Phase I study consists of a Phase Ia portion and a Phase Ib portion. The Phase Ia portion (N=14 subjects) consists of an open-label, single-arm, study design. The potentially conducted Phase Ib portion of the study (N=28 subjects) consists of a double-blind, randomized, placebo-controlled study design. The Phase Ia portion is an open-label, dose escalation of Allogeneic Cardiosphere-Derived Cells (CDCs).
The placebo study arm only applies to the Phase Ib portion of the study design. The Phase Ia portion (N=14 subjects) consists of an open-label, single-arm, study design. The potentially conducted Phase Ib portion of the study (N=28 subjects) consists of a double-blind, randomized, placebo-controlled study design.
