The purpose of this submission is to obtain clearance for the use of x-ray irradiation as an alternative terminal sterilization method and the use of animal sourced materials from a new additional supplier in New Zealand and new abattoir in Australia. In addition, the product is being offered in two new volumes: 0.125 g (particle size 0.25 - 1.0 mm), 1.0 g (particle size 0.25 - 1.0 mm), and 1.0 g (particle size 1.0 - 2.0 mm). These changes do not raise different questions of safety and effectiveness and are addressed by the performance data cited below and provided within the submission.

Further to these changes, the product shelf life has been extended from 3 years to 4 years, storage temperatures for raw bones were updated, the product specification was clarified, the secondary packaging for the 20 mL vial was changed to a blister pack, and the gamma sterilization load was increased to improve production capacity. These changes were assessed, validated as appropriate, and documented under the quality system.

{7}------------------------------------------------

VII. Performance Data

Mechanical testing (K122984), biocompatibility (K190754), sterilization (K122894), shelf-life (K190754), and non-clinical performance testing (K122894) from the applicant's own predicate and reference device were leveraged in support of substantial equivalence.

Based on the results of assessment, the following evaluations were undertaken:

. sterilization validation per ISO 11137-1, ISO 11137-2, and ISO 11137-3
biocompatibility assessments per ISO 10993-1 and ISO 10993-5
stability testing per ICH Q1A (R) stability testing guidelines ●
characterization of structural and mechanical properties
viral inactivation studies per ISO 22442-3 and ICH Q5A(R2) Draft Version ●

In addition, validation of raw materials from the new supplier was undertaken. The physical and chemical composition and appearance of the validation lots were characterized using the same tests and acceptance criteria as the final, finished product.

VIII. Conclusion

The subject device is identical to the predicate device. The addition of x-ray irradiation as an alternative terminal sterilization method and introduction of an additional raw material supplier do not raise different questions of safety and effectiveness. Therefore, it is concluded that Geistlich Bio-Oss® is substantially equivalent to the identified predicate device.
