ORTHOUNION
A multi-centre, open-label, randomized, comparative clinical trial of two different doses of bone marrow autologous human mesenchymal stem cells plus biomaterial versus iliac crest autologous graft, for bone healing in non-union after long bone fracturesThis clinical trial involves two comparative analyses:
Comparison of efficacy in terms of superiority of hBM-MSCs + biomaterial (both experimental arms, low and high doses) versus iliac crest autologus graft (active comparator arm). The principal endpoint is bone consolidation at one year, defined as a combination of clinical and radiological improvements: radiological consolidation (considered as a new bone formation across the fracture site visible in 3/4 cortices, on at least 3/4 views, qualitative analysis) without pain (with and without weight bearing) and without further reoperation in the callus site.
Comparison of efficacy in terms of non-inferiority (target delta of 0.10 points) of low dose hBM-MSC+Biomaterial versus high dose of hBM-MSC+Biomaterial. The principal endpoint is the radiological consolidation, measured in a scale from 0 to 1, considering the mean consolidation of 0.6875 points (quantitative analysis).
