Bonus BioGroup

Status and phase: Completed; Phase 2; Phase 1

Conditions: Bone Void in the Maxillofacial Area

Treatments: Procedure: Single Arm - Liposuction procedure and BonoFill transplantation will be done for all subjects on study

Study type: Interventional

CP-BNS-02

Details and patient eligibility

About

Phase I/II open label first in human single center clinical study, is to evaluate the safety and the efficacy of BonoFill as bone filler containing the patient own (autologous) adipose tissue derived cells (HATDCs) in reconstructing the Bone Void in the maxillofacial area approximately 6 month follow up after implantation in the following two clinical indications:

1. Bone augmentation (e.g. sinus augmentation)
2. Bone grafting after removal of cysts from jaws

Full description

Primary endpoint: The implantation of BonoFill 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 implantation of BonoFill to the maxillary or mandible void is efficient under the following conditions: Following BonoFill 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.

Enrollment: 11 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
