Intended Use

PROGENIX® DBM Putty and PROGENIX® Plus are intended for the augmentation of deficient maxillary and mandibular alveolar ridges and the treatment of oralmaxillofacial and dental intraosseous defects including but not limited to: Ridge augmentation Filling of cystic defect Filling of extraction sites Filling of lesions of periodontal origin Craniofacial augmentation Filling of defects of endodontic origin Mandibular reconstruction Repair of traumatic defects of the alveolar ridge, excluding maxillary and mandibular fracture Filling of resection defects in benign bone tumors, benign cysts or other osseous defects in the alveolar ridge wall.

Device Story

PROGENIX® Plus is a resorbable bone void filler for oralmaxillofacial and dental applications. It consists of human demineralized bone matrix (DBM) and a biocompatible carrier (bovine collagen and sodium alginate) mixed in phosphate buffered saline. The 'Plus' formulation incorporates two different sized DBM particles. The device is provided in a ready-to-use, malleable, flowable form. It is intended for single use by surgeons to fill osseous defects; it does not provide mechanical strength. The device is osteoinductive and osteoconductive, supporting bony ingrowth while resorbing at a rate consistent with natural healing. Surgeons manipulate the material into the surgical site to facilitate bone repair. Viral inactivation is achieved through validated processing of the tissue and collagen components.

Clinical Evidence

No clinical data provided. Evidence is based on bench testing, specifically a validated athymic nude rat assay to confirm osteoinductivity. The assay requires histologic evidence of osteoblasts, chondroblasts, and/or woven bone formation. Viral inactivation was validated through testing against a panel of clinically relevant viruses.

Technological Characteristics

Bone void filler composed of human demineralized bone matrix (DBM) and a carrier of bovine collagen and sodium alginate in phosphate buffered saline. Malleable, flowable form. Osteoinductive and osteoconductive. Sterilized via validated viral inactivation processing steps. Non-mechanical, single-use device.

Indications for Use

Indicated for patients requiring augmentation of deficient maxillary and mandibular alveolar ridges or treatment of oralmaxillofacial and dental intraosseous defects, including ridge augmentation, cystic defects, extraction sites, periodontal lesions, craniofacial augmentation, endodontic defects, mandibular reconstruction, traumatic alveolar ridge defects (excluding fractures), and resection defects in benign bone tumors or cysts.

Regulatory Classification

Identification

Bone grafting material is a material such as hydroxyapatite, tricalcium phosphate, polylactic and polyglycolic acids, or collagen, that is intended to fill, augment, or reconstruct periodontal or bony defects of the oral and maxillofacial region.

Special Controls

*Classification.* (1) Class II (special controls) for bone grafting materials that do not contain a drug that is a therapeutic biologic. The special control is FDA's “Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices.” (See § 872.1(e) for the availability of this guidance document.)(2) Class III (premarket approval) for bone grafting materials that contain a drug that is a therapeutic biologic. Bone grafting materials that contain a drug that is a therapeutic biologic, such as biological response modifiers, require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

# Medtronic Sofamor Danek PROGENIX® Plus 510(k) Summary June 2008

- Ryan Massey Contact: Regulatory Affairs Specialist
- PROGENIX® Plus ll. Proposed Proprietary Trade Name: Resorbable calcium salt bone Classification Name: void filler device NUN Product Code: Regulation No .: 872.3930

### Product Description/Purpose of Application ���.

PROGENIX® contains human demineralized bone matrix (DBM) in a biocompatible carrier. The carrier is a mixture of bovine collagen with a natural polysaccharide (sodium alginate). The components are mixed in phosphate buffered saline to achieve a flowable or moldable consistency. PROGENIX® is available in two forms: Putty and Plus. The PROGENIX® Plus version contains two different sized demineralized bone particles.

PROGENIX® DBM Putty and PROGENIX® Plus are single use products intended for use in the oralmaxillofacial region. Additionally, these products are not designed to impart any mechanical strength to the surgical site. Both versions are provided in ready-to-use malleable forms that may be molded or manipulated by the surgeon into various shapes. These products have been shown to be osteoinductive in an athymic rat assay, as well as osteoconductive, allowing for bony ingrowth across the graft site while resorbing at a rate consistent with bony healing.

{1}------------------------------------------------

The purpose of this Special 510(k): Device Modification application is to include a new formulation (PROGENIX® Plus) to the previously cleared PROGENIX® product line. The subject device, like the predicate device, contains human demineralized bone matrix (DBM) in a biocompatible carrier, however PROGENIX® Plus will also contain two different sized demineralized bone particles. The indications for PROGENIX® Plus will be identical to the previously cleared PROGENIX® product (K080462, SE 05/13/08).

#### IV. Indications

PROGENIX® DBM Putty and PROGENIX® Plus are intended for the augmentation of deficient maxillary and mandibular alveolar ridges and the treatment of oralmaxillofacial and dental intraosseous defects including but not limited to:

Ridge augmentation Filling of cystic defect Filling of extraction sites Filling of lesions of periodontal origin Craniofacial augmentation Filling of defects of endodontic origin Mandibular reconstruction Repair of traumatic defects of the alveolar ridge, excluding maxillary and mandibular fracture Filling of resection defects in benign bone tumors, benign cysts or other osseous defects in the alveolar ridge wall.

# V. Substantial Equivalence

Documentation is provided that demonstrates PROGENIX® Plus is substantially equivalent to previously cleared bone void fillers such as PROGENIX® DBM

1081950

{2}------------------------------------------------

Putty (Medtronic Sofamor Danek, K080462, SE 05/13/08) and GRAFTON® DBM Crunch (Osteotech Inc., K051188, SE 01/03/06).

# Osteoinductivity Potential VI.

All DBM used in the preparation of PROGENIX® Plus must induce bone formation when evaluated in a validated athymic nude rat assay. Additionally, PROGENIX® must also induce bone formation in this assay system prior to being released for use. The raw material and final product screening must show histologic evidence of osteoinduction through the presence of osteoblasts, chrondoblasts and/or woven bone. Osteoinduction assay results using the athymic rat assay should not be interpreted to predict clinical performance in human subjects.

#### VIII. Viral Inactivation

PROGENIX® Plus is produced from tissue and collagen that undergoes processing steps validated to inactivate a panel of viruses representative of those that are clinically relevant. The cortical bone used to produce the DBM undergoes a proprietary process demonstrated to inactivate viruses. Furthermore, the DBM undergoes additional steps that are also effective at inactivating viruses. The viral inactivation testing demonstrates suitable viral inactivation potential of the processing methods for a wide range of potential human viruses. These processing steps further reduce the risk of viral contamination beyond donor screening and testing.
