Lead Sponsor
Christian Medical College, Vellore, India
Brief Summary

An exploratory, open label, multiple dose, phase I/II trial (n=15) evaluating safety and efficacy of intravenous and intraosseous infusion of allogeneic expanded fetal mesenchymal stem cells (MSC) for the treatment of severe Osteogenesis Imperfecta (OI) compared with historical and untreated prospective controls.

GroupInterventionDescription
TreatmentBOOST cellsAdministration of four doses of BOOST cells with the first dose between 1-4 years of age and the three additional doses at +4, +8 and +12 months after the first dose. Each dose is 3x10\^6 MSC/kg body weight.
Primary Outcome Measures
NameTimeMethod
Safety and tolerability measured as seriousness, severity and frequency of treatment related adverse events (AEs)From baseline to 16 months follow up

The primary endpoint is safety and tolerability measured as seriousness, severity and frequency of treatment related adverse events (AEs)/Serious AE (SAE)/Suspected Unexpected Serious Adverse Reaction (SUSAR)with specific focus on the following:

1. Vital signs in conjunction with the MSC infusion

2. Transfusion reactions (infusion toxicity, embolism, allergy, infections)

3. Immune reaction towards the cells, donor-specific antibodies, graft rejection, Graft versus Host Disease, autoimmunity)

4. Tumourigenicity

5. Mortality/morbidity
