About this study

AdvanCore is a porous beta-tricalcium phosphate CE-marked medical device. It is intended to be used to aid in the bone regeneration process in situations where bone is damaged beyond the limits of its self-healing ability. The target population is constituted by adult subjects in need of bone grafting of mechanically unaffected, pathologic, or traumatic bone defects caused by surgery or trauma.

AdvanCore is produced in the shape of blocks, wedges, or granules in different sizes and is surgically placed into spaces between or around broken bone (fractures) or in holes (defects). The site to be augmented must be free from infection and free from soft or granulation tissue. AdvanCore must contact cancelous bone and may be pressed into the defect area by hand or shaped more accurately to fit the area. It can be used as is, impregnated with subjects' blood/ bone marrow and/ or mixed with medicinal substances under the responsibility of the qualified professionals.

AdvanCore acts as a temporary scaffold and is not intended to provide mechanical support during the healing process. Additional therapy for load-bearing (such as osteosynthesis) is indicated if the bone does not comply with the required biomechanical function.

The study on safety and performance of AdvanCore bone void filler will be conducted in European sites and include up to 190 subjects requiring bone implant surgery, which will be divided in 3 different groups:

  • Group 1- This group is formed by those subjects with long-bone injuries. The treatment of this type of lesion may be performed using blocks, wedges, or granules.
  • Group 2- Subjects included in this group suffer from spine injuries, which can be treated using granules.
  • Group 3- Those subjects with maxillofacial injuries are included in this group. In this case, granules are used to treat the lesion.

The primary safety endpoint of this study is defined as freedom of bone reintervention due to AdvanCore usage at 6 months, analyzing the occurrence of Adverse Events or Serious Adverse Events [(S)AEs] related to the device usage and/ or AdvanCore procedure that may lead to subjects' reoperation.

The primary performance endpoint will analyze the AdvanCore osteointegration after 6 months of surgery, studying the percentage of subjects with successful osteointegration at the defined time point. AdvanCore will be considered successfully osteointegrated when no presence of fibrotic tissue surrounding the implant is detected.

Secondary endpoints planned for this clinical investigation are listed below:

  • Evaluation of (S)AEs related to the procedure;
  • Evaluation of (S)AEs related to the device;
  • Freedom of reintervention due to AdvanCore usage;
  • AdvanCore osteointegration;
  • AdvanCore resorption rate, assessed as the percentage of subjects with successful bone graft resorption.

The clinical investigation has been designed to involve as little pain, discomfort, fear, and any other foreseeable risk as possible for subjects.

Treatment and study plan

AdvanCore bone grafting

Procedure

AdvanCore medical device is implanted making sure that is in direct contact with all surfaces of the defect area.

Primary outcomes

  1. Freedom of bone reintervention (safety)

    Time frame: 6 months post-surgery

    The primary safety endpoint is defined as freedom of bone reintervention due to AdvanCore usage at 6 months, analyzing the occurrence of (S)AEs related to the device usage and/ or AdvanCore procedure that may lead to subjects' reoperation.

  2. Successful osteointegration (performance)

    Time frame: 6 months post-surgery

    The primary performance endpoint will analyze the AdvanCore integration at 6 months of surgery. This process is defined as osteointegration, which refers to the direct structural and functional connection of the living bone with the surface of the implant. The implant osteointegration will be assessed by imaging techniques selected according to the current clinical practices of each site. In this regard, the primary performance endpoint will be analyzed by considering the percentage of subjects with successful osteointegration at the defined timeline. AdvanCore will be considered successfully osteointegrated when the presence of fibrotic tissue surrounding the implant is not detected.
