|---|---|
| Main Objective: The goal of this study is to assess the safety and the efficacy of beta-tricalcium phosphate biomaterial containing autologous mesenchymal stem cells. Primary Objective - Safety: To document absence of complications at the site of femoral bone defect. To assess overall profile of untoward events in study subjects. ;Secondary Objective: Safety: Incidence of other study treatment-emergent adverse events. Overall safety. Efficacy: To assess the quality of healing of femoral bone defects as evaluated by Harris Hip Score, plain X-rays and densitometry, in comparison to referral data. ;Primary end point(s): Primary endpoint: Safety: To assess an absence of complications at the site of revision total hip arthroplasty.;Timepoint(s) of evaluation of this end point: At each visit since Visit V (1 days post-surgery) until Visit X (12 months postsurgery). | — |
