Description détaillée
This is an open label study, intended as a safety and efficacy assessment prior to a full comparator study. In this Phase I study, cells administered will be delivered in 6-10 intramyocardial injections that will be tested in 20 patients and 10 patients will be controls with a total of 30 HLHS patients.
A total of 30 patients with HLHS will be enrolled in a staged enrollment process. In this open-labeled study, a maximum of 20 patients will eventually receive intramyocardial injection of the allogeneic mesenchymal stem cells and 10 control patients with no cell injection. The enrollment of the patients will occur in two stages groups: Group A and Group B. In Group A, 10 consecutive HLHS patients will be initially enrolled in the allogenic MSCs treatment arm to determine feasibility and safety. After 6 months of the last enrolled patient in Group A, all Group A patients will be assessed in order to determine whether it is feasible and safe, including the harvesting, processing, and administering of the allogeneic MSCs. Thereafter, Group B will start enrolling a total of 20 HLHS patients which will be randomized to the treatment and control arms in a 1:1 ratio, respectively, in order to have 10 allogeneic MSCs-treated patient and 10 control patients. At the completion of this Phase I clinical study, the total enrolled cohort will be 20 patients treated with allogeneic MSCs and 10 patients in the control arm.

Intervention / Traitement |
|---|---|
|
Expérimental: Group A - Allo-hMSCs
Group A: Fifteen (20) patients will be treated with Allogenic human mesenchymal stem cells (Allo-hMSCs): A concentration of 5 million cells/ml delivered in a dose of 2.5 x 10^5 cells per kg of recipient (5 million/20kg) Allo-hMSCs.
The entire dose of the cells will be divided and delivered in 6-10 open intramyocardial injections during the BDCPA operation.
