A phase II clinical trial to assess the effect of HC-SVT-1001 and HC-SVT-1002 in the surgical treatment of nonunions fractures of long bones

A phase II clinical trial to assess the effect of HC-SVT-1001 (autologous fat stem adult mesenchymal cells expanded and combined with a tricalcium phosphate biomaterial) and HC-SVT-1002 (allogeneic fat stem adult mesenchymal cells expanded and combined with a tricalcium phosphate biomaterial) in the surgical treatment of atrophic pseudarthrosis of long bones

Design outcomes

Primary

MeasureTime frame
Main Objective: - To evaluate the safety of HC-SVT-1001 and HC-SVT-1002 in the surgical treatment of atrophic nonunion in long bones by recording of adverse events. - To evaluate the effectiveness by appearance of signs of osseous setting formation at least in 2 out of 3 cortical (tibia) or 3 out of 4 cortical (humerus, femur, cubitus, radius) within 6 months after surgery.;Secondary Objective: Conduct a comparative statistical analysis that relates fundamental aspects like incidence of adverse effects, complications, healing time, etc. between the 12 patients of this study and the data of 14 consecutive cases of refractory nonunion of long bones that have been treated since 1-9-2009 with 40x106 autologous fat stem adult mesenchymal cells, expanded following GMP procedures of IBGM Valladolid and under AEMPS compassionate use requirements.;Primary end point(s): To evaluate the effectiveness by mean of radiological methods on the appearance of signs of osseous setting formation within 6 months after surgery.;Timepoint(s) of evaluation of this end point: Radiographic series performed in pre-surgery and surgery visit and follow-up visits (1 month after surgery and at 3, 4 and 6 months)

Secondary

MeasureTime frame
Secondary end point(s): Conduct a comparative statistical analysis that relates fundamental aspects like incidence of adverse effects, complications, healing time, etc. between the 12 patients of this study and the data of 14 consecutive cases of refractory nonunion of long bones that have been treated since 1-9-2009 with 40x106 autologous fat stem adult mesenchymal cells, expanded following GMP procedures of IBGM Valladolid and under AEMPS compassionate use requirements.;Timepoint(s) of evaluation of this end point: End of study
