TERCELOI: Mesenchymal Stem Cell Based Therapy for the Treatment of Osteogenesis Imperfecta
Study Details
Study Description
Brief Summary
The purpose of this study is to determine the safety and effectiveness of five infusions of characterized HLA-identical MSC in non immunosuppressed children with Osteogenesis Imperfecta (OI).

Phase 1 |
Detailed Description
The principal aim of this trial is to assess the safety of non-mutated HLA-identical Mesenchymal stem cell (MSC) transplantation for OI pediatric patients irrespective of treatment with biphosphonates. Since MSC are inherently non-immunogenic and do not elicit proliferation of allogeneic lymphocytes (in co-culture experiments), a cell therapy based on HLA-identical or histocompatible (at least 5 shared out of 6 HLA antigens) allogenic MSC may be accomplished without subjecting the patients to immunosuppressor treatment. Adverse secondary effects due to immunosuppressor treatment will be avoided using this strategy thus patients may benefit from two cellular infusions. The patients will be followed for 2 years post their fifth and last MSC infusion.

Outcome Measures
Primary Outcome Measures
- Adverse Events as a Measure of Safety [up to 2 years post last MSCs infusion]
Secondary Outcome Measures
- bone mineral density [up to 2 years post last MSCs infusion]
- fracture rate [up to 2 years post last MSCs infusion]
- growth velocity [up to 2 years post last MSCs infusion]
- change from baseline in degree of functionality [up to 2 years post last MSCs infusion]
9 question survey using a Bleck functional scale
- change from baseline in well-being [up to 2 years post last MSCs infusion]
A 20 item questionnaire designed to evaluate the well-being will be used
