E.3 | Principal inclusion criteria |
1- All patients having received at least one infusion of HepaStem during a previous interventional clinical study conducted by Promethera Biosciences. 2- Written Informed Consent. For a patient who is a minor (according to the national regulations), and for adult patients legally incapable: the parents or legal representative have provided a signed informed consent before enrolment. If the patient is capable of signing, he/she is required to sign an assent in parallel. For adult patient (legally capable): patient has provided a written informed consent before enrolment.

E.5 End points |
E.5.1 | Primary end point(s) |
Occurrence of Adverse Events of Specific Interest (AESI): - Event with fatal outcome (Death) - Orthotopic Liver Transplantation (OLT) and Outcome. - Development of Malignancy or unwanted tissue formation in different organs (tumor malignant or not). - Disease linked to transmission of adventitious agents or reactivation of latent pathogens. -Any AE which in the opinion of the investigator has a plausible causal relationship to HepaStem.
These AESI should be considered as medically important and reported as SAE.
