Filling Bone Defects/Voids With Autologous BonoFill-II for Maxillofacial Bone Regeneration

Phase 1

• Conditions: Bone Augmentation; Bone Grafts
• Interventions: Biological: BonoFill-II

• Registration Number: NCT02842619
• Lead Sponsor: BonusBio Group Ltd

Brief Summary

The purpose of this clinical study is to evaluate the safety and the efficacy of BonoFill-II as a bone filler containing the patient's own (autologous) adipose (fat) tissue-derived cells in reconstructing bone in two clinical indications:

1. Bone augmentation (e.g. sinus augmentation)

2. Bone grafting after removal of cysts from jaws

Detailed Description

Primary endpoint:

The transplantation of BonoFill-II to the maxillary or mandible defect/void is safe under the following conditions: No chronic bone infection (Osteomyelitis); no significant changes in complete blood count (CBC) and in general health.

Secondary endpoint:

The transplantation of BonoFill-II to the maxillary or mandible void is efficient under the following conditions: Following BonoFill-II implantation, the bone regeneration in the operated site was significantly accelerated. Also, the bone defects/voids were filled with a significant amount of bone tissue.

Primary Outcome Measures

Name	Time	Method
Safety of Bonofill-ll Administration	6-month clinical Follow Up	The study will assess the safety of the BonoFill-II drug product post transplantation by demonstrating no treatment-related adverse events such as chronic bone infection (Osteomyelitis) or significant changes in complete blood counts. adverse events will be assessed by type, severity, seriousness, relatedness, incidence, and duration.
Efficacy of Bonofill-ll Administration	6-month clinical Follow Up	Following BonoFill-II transplantation, the bone regeneration in the operated site will be evaluated using CT or panoramic X Ray. Bone formation at the implantation site inside the maxillary sinus will be evaluated by measuring the bone height (mm) at the end of the study (residual + Augmented bone at 3 evenly-spaced locations) and comparing to measurements of bone height of the residual bone only prior to Bonofill-ll administration. Efficacy will be evaluated also by having a stable dental implants at the uncovering procedure by the end of the study.
