入选标准
- •Males and females ≥18 years of age
- •LVEF ≤35% on echocardiogram within 12 months of randomization to undergo MRI
- •Screening cardiac MRI at baseline with:
- •Ejection fraction ≤40% No significant hyper enhancement on MRI scan in the opinion of the central imaging lab reviewer
- •Patients with non-ischemic heart failure etiology, as documented by absent or non-obstructive coronary artery disease on x-ray angiography or coronary computed tomography
- •Patients with history of heart failure and treated for at least three months with GDMT
- •NYHA class II-III symptoms
- •Ability to understand and provide signed informed consent
- •Reasonable expectation that patient will receive standard post-treatment care and attend all scheduled safety follow-up visits
排除标准
- •Pregnant or nursing women or those of childbearing age and not using an effective method of contraception
- •History of stroke within 3 months
- •Cardiac surgery within 3 months prior to randomization or the likelihood of a requirement for such procedures during the study period
- •Current ICD or CRT or implantation planned within 6 months of infusion
- •Presence of clinically significant, uncorrected valvular heart disease, hypertrophic or restrictive cardiomyopathy, active myocarditis, or uncontrolled hypertension
- •History of cardiac arrest or life-threatening arrhythmias within 3 months
- •Treatment with parenteral inotropic agents within 1 month of randomization
- •Anticipated cardiac transplantation within 1 year
- •Illness other than heart failure with life expectancy less than 1 year
- •Received an experimental drug or device within 30 days of randomization
- •Left ventricular assist device or implantation planned in the next 6 months
- •Patients with complex congenital heart disease
- •Uncontrolled seizure disorder
- •Presence of immune deficiency
- •Clinically significant hematologic, hepatic, or renal impairment as determined by screening clinical laboratory tests:
- •Liver disease = ALT or AST > 3x normal, alkaline phosphatase or bilirubin >2x normal)
- •Renal disease = estimated glomerular filtration rate as assessed by the MDRD formula <30 ml/min
- •Hematologic = Unexplained leukocytosis >10 or hemoglobin < 9gm/dl
- •Presence of any other clinically-significant medical condition, psychiatric condition, or laboratory abnormality, that in the judgment of the investigator or sponsor for which participation in the study would pose a safety risk to the subject
- •Inability to comply with the conditions of the protocol
- •Malignancy within the previous five years, except adequately treated basal cell carcinoma, provided that it is neither infiltrating nor sclerosing, and carcinoma in situ of the cervix
- •Active myocarditis or early postpartum cardiomyopathy (within six months).
- •Systemic corticosteroids, cytostatics, immunosuppressive drug therapy (cyclophosphamide, methotrexate, cyclosporine, azathioprine, etc.), and DNA depleting or cytotoxic drugs taken within four weeks prior to study treatment
- •Allergy to sodium citrate or any "caine" type of local anesthetic
- •Any contraindication for gadolinium use for MRI
- •Patient scheduled for hospice care
- •Clinically relevant abnormal findings in the clinical history, physical examination, ECG, or laboratory tests at the screening assessment that would interfere with the objectives of the study or would preclude safe completion of the study. Abnormal findings could include: known HIV infection or other immunodeficiency state, chronic active viral infection (such as hepatitis B or C), acute systemic infections (defined as patients undergoing treatment with antibiotics), gastrointestinal tract bleeding, or any severe or acute concomitant illness or injury
- •Any other medical, social, or geographical factor that would make it unlikely that the patient could comply with study procedures (e.g., alcohol abuse, lack of permanent residence, severe depression, disorientation, distant location, or noncompliance)
研究组 & 干预措施
Placebo:Lactated Ringer's Solution (LRS)
Placebo Comparator
Intervention: One time intravenous infusion of 1.5mL/kg Lactated Ringer's Solution (LRS) administered at a constant rate of approximately 2mL/min.
干预措施: Lactated Ringer's Solution (Drug)
Experimental: Human (aMBMC)
Experimental
Intervention: One time intravenous infusion of 1.5 million (aMBMC) per kg administered at approximately 2mL/min. Maximum dose as for 100kg subject or 150 million cells for any subject 100kg or more.
干预措施: Allogeneic Mesenchymal Bone Marrow Cells (aMBMC) (Drug)
结局指标
主要结局
Safety Will be Evaluated by Number of AE
时间窗: Total AEs and SAEs within 450 days post-infusion
As identified in the SAP, the safety analysis was the primary objective and was evaluated by the number of AEs
次要结局
- Change in LVEF From Baseline to Day 90 Post-initial Infusion.(Baseline to Day 90)
