Below the logo is the text "ORMED GRUP MEDIKAL TUR.SAG.HIZ.SAN.VE.TIC.LTD.STI". The text is in a smaller font size than the logo. The logo is simple and modern. Regarding chemical composition comparison, while the primary predicate device contains zirconium dioxide, the subject device contains barium sulfate in the cement powder as an X ray contrast medium. On the other hand, secondary predicate device contains barium sulfate as the subject device. Both materials are used in commercialized bone cements as an X ray contrast medium. The subject device and secondary predicate device contain 1g gentamicin sulfate, on the contrary primary predicate device contains 0.5g gentamicin sulfate. Gentamicin sulfate is bactericidal and is active against many strains of Gram-positive and Gram-negative pathogens. As per gentamicin sulfate ratio is higher than the primary predicate device antibacterial efficacy can be considered as substantially equivalent to primary predicate device. Antibacterial efficacy tests are performed to subject device. On the other hand, release ratio of Gentamicin is important both in dosage and total release duration. OGM® 1A is subjected to Gentamicin release test comparatively with the predicate device. Lastly, gentamicin has a negative effect on product mechanical and physical properties. ISO 5833 tests are applied to OGM® 1A and demonstrated compliance. Chemical formulas between predicate devices and subject device have slight differences. The primary predicate device contains chlorophyll additive serves as marking of the bone cement at the site of the operation. The subject device and secondary predicate device do not contain chlorophyll, but it is still visible as off white instead of green which chlorophyll provides for primary predicate device. Subject device has been carried out the ISO 5833 performance tests and ISO 10993 biocompatibility tests. ISO 5833 requirements are fulfilled. ISO 10993 test results demonstrates biological safety. Endotoxin testing was performed to OGM® 1A according to USP Endotoxin Reference Standard. The results meet the limit value (20 EU/device). {13}------------------------------------------------ Image /page/13/Picture/0 description: The image shows the logo for ORMED GRUP MEDIKAL TUR.SAG.HIZ.SAN.VE.TIC.LTD.STI. The logo features the letters "OCM" in a stylized font, with the "O" and "C" in blue and the "M" in black. Below the letters is the company name in smaller, all-caps letters. The logo is simple and professional, and it is likely used on the company's website, marketing materials, and other branding materials. ## Conclusion The non-clinical tests comply with the requirement of ISO 5833 and ASTM F451. Biological safety has been demonstrated according to the ISO 10993-1. Side-by-side mechanical tests were also performed according to ASTM D732, ASTM F2118 standards and the results are similar when compared to predicate devices. Endotoxin testing was performed to OGM® 1 and OGM® 1A according to USP Endotoxin Reference Standard. The results meet the limit value (20 EU/device). Antibacterial efficiency testing was performed according to the AATC and it is showed that the device is efficient to the E.Coli.
