Summary

The purpose of this study is to test whether Lomecel-B™ works in treating patients with hypoplastic left heart syndrome (HLHS) and to gather additional information about the safety of Lomecel-B. Lomecel-B contains human mesenchymal stem cells (MSCs) as the active ingredient. MSCs are special cells in the body that are able to change into other types of cells, such as heart, blood, and muscle cells. MSCs are found in various tissues of the body, such as the bone marrow, which is the spongy tissue inside of your bones. Lomecel-B uses MSCs from bone marrow of unrelated young healthy donors. These are called "allogeneic", and do not require donor matching to the patient.

Eligibility Criteria

Inclusion:

All participants must have HLHS (includes all types) requiring Stage II palliation (Glenn or Hemi-Fontan operation).

Exclusion:

1. Requirement for ongoing mechanical circulatory support immediately prior to Stage II palliation within 5 days
2. Need for concomitant surgery for aortic coarctation or tricuspid valve repair or Endocardial fibroelastosis (EFE) resection or left ventricle recruitment procedures
3. Undergoing the Stage I (Norwood) procedure that does not have HLHS
4. Serum positivity for: human immunodeficiency virus (HIV); hepatitis B virus surface antigen (HBV BsAg); and/or viremic hepatitis C virus (HCV). This criterion can be ascertained by one of three ways:

1. Documented history of mother's testing conducted during pregnancy
2. Documented history of participants testing.
3. If above documentation is not available blood will be obtained from participant at Screening/Baseline.
5. Parent/guardian that is unwilling or unable to comply with necessary follow-up
6. Unsuitability for the study based on the Investigator's clinical opinion
7. Known hypersensitivity to dimethyl sulfoxide (DMSO)
8. Presence of a pacemaker, or anticipated placement of a pacemaker, at the time of the Stage II palliation
