Clinical Trial Summary

A prospective, randomized, evaluator-blinded, controlled study for subjects with open tibial fractures classified as Gustilo type II, IIIA or IIIB (see Appendix 1) who will receive bone graft implantation for the potential of delayed union or non-union within 3 months of fracture. Subjects will be followed for safety and clinical performance for the main study period of 30 weeks and an extension follow-up period up to 52 weeks after bone graft implantation.


Description:

Study Objectives: - Primary objectives o To determine the overall success of effectiveness (clinical and radiographic success) and safety (lack of serious product-related AEs and lack of secondary intervention) of OIF/beta-TCP within 30 weeks after bone graft implantation in subjects with open tibial fractures in need of bone grafting. - Secondary objectives - To determine radiographic union in different treatment groups; - To determine clinical union in different treatment groups; - To assess the safety of OIF - To assess the immunogenicity of OIF; - To determine the pharmacokinetics of OIF.

Isolated open tibial fractures, which is classified as below and within 3 months of initial fracture, and soft tissue stable without any sign of active infection; 1. Gustilo type II with fracture gap at least 0.5 cm in length or severe damage to the periosteum after debridement or 2. Gustilo type IIIA with fracture gap at least 0.5 cm in length or IIIB with fracture gap at least 0.5 cm in length; 4. Subjects with unilateral open tibial fractures; 5. Willing to provide signed informed consent form (ICF) prior to participation in any study-related procedures and adhere to the study requirements for the length of the trial. Exclusion Criteria: Subjects will be excluded if ANY of the following exclusion criteria apply: 1.
