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

Phase I/II Open Label First in Human Single Center Clinical Study Aimed to Evaluate the Safety and Efficacy of BonoFill-II in Reconstructing Maxillofacial Bone

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

Study Overview

• Status: Completed
• Conditions: Bone Augmentation; Bone Grafts
• Intervention / Treatment: Biological: BonoFill-II

Detailed Description

Safety 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.

Efficacy endpoint:

The transplantation of BonoFill-II to the maxillary or mandible void is efficient: the bone defects/voids are filled with at least 8mm of total bone height at the transplanted area.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Intervention Arm; 1 Arm - IMP treatment arm

Biological: BonoFill-II; Sinus augmentation - Surgery will be performed by either open or close sinus augmentation as per investigator discretion and as per common medical practice. After the elevation, BonoFill-II will be transplanted on the residual sub-antral bone. Bone grafting after removal of cysts from jaws - Treatment will be performed according to the size of the cyst: in relatively small cyst total enucleation will be performed. In large cysts, a process of marsupialization will be performed. The entire cyst will be removed, including the epithelium layer, and the BonoFill-II product will be used for filling.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety of Bonofill-ll Administration	The study will assess the safety of the BonoFill-II drug product post transplantation by demonstrating No chronic bone infection (Osteomyelitis); no significant changes in complete blood count (CBC) and in general health.	6-month clinical Follow Up
Efficacy of Bonofill-ll Administration	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 at the end of the study (residual + Augmented bone at 3 evenly-spaced locations). Successful bone regeneration is achieved if: Bone formation inside the maxillary sinus or bone void, in the area of dental implantation defined at Visit 1 (prior to BonoFill-ll transplantation), with average height (residual + augmented bone) of at least 8mm, OR; Bone formation inside the maxillary sinus in the area of dental implantation defined at Visit 1 (prior to BonoFill-II transplantation), allowing successful dental implantation.	6-month clinical Follow Up
