The first 3 subjects will be administered 50 x 10\\^6 ULSCs reconstituted in PBS with 1% human serum albumin in a volume of 250 ml, and monitored for adverse events or toxicities, immediately following dosing, and again at 30 days. Safety endpoints will be reviewed by the DSMB and depending on the response, the dose will be escalated to 100 x 10\\^6 and 200 x 10\\^6 ULSC in a constant 250 ml volume. We will enroll only 9 subjects in the case that no subject experiences toxicity, only expanding the cohort in the event that a subject experiences toxicity at a particular dose.\n\nThis specific dose escalation approach is based on the following considerations:\n\nThere is not yet a standard dosing regimen for cell therapy in heart failure patients. The previous MSC trial in LVAD patients provided 150 million cells. The RIMECARD trial (Bartolucci et al, Circ Res 2017 Oct 27;121(10):1192-1204. PMID 28974553) provided umbilical cord-derived MSC for patients with heart failure via intravenous infusions of 1x106 cells/kg. Similarly, another Phase IIa trial of MSCs in HFrEF used 1.5x106 cells/kg (Butler et al., Circ Res 2017 Jan 20;120(2):332-340. PMID 27856497). Since our LVAD patients range in size from 50 to \\> 100kg, we believe the selected range of doses is reasonable for this patient population.\n\nIn addition, in ongoing studies in COVID 19 ARDS, IND# 19979, we have provided 100 x 106 ULSCs with no adverse safety signals. Moreover, in our non-clinical animal models, we demonstrated safety at doses ranging from a high dose of 1 x 106 cells/mouse, which is equivalent to approximately 5 x 107 cells/kg in humans and a low dose of 5 x 104 cells/mouse which is equivalent to approximately 2.5 x 106 cells/kg in humans. The dose tested in the high dose preclinical study would scale to administration of over 2.5 billion cells in an individual weighing 100 pounds.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
