Dear David P. Mayer:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

The subject and predicate device have similar indications for use and have the same intended use. The technological characteristics of the subject and predicate devices are similar in that they are polyurethane-based, are lubricated with silicone oil, and have the same shelf-life duration. The subject and predicate condoms also have identical formulations. There are differences in dimensions and specifications; the subject device has reduced thickness and length compared to the predicate device. These differences do not raise different questions of safety and effectiveness.

9. Summary of Non-Clinical Performance Testing

Biocompatibility:

Biocompatibility studies, including Acute Systemic Toxicity, Vaginal Irritation Testing, Cytotoxicity and Sensitization testing were performed in accordance with a surface medical device with limited contact duration (<24 hr contact with skin and mucosal membranes) per the 2023 FDA guidance document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" as follows:

Cytotoxicity (ISO 10993-5:2009/R 2014)
Sensitization (ISO 10993-10:2010/R 2014)
Vaginal Irritation (ISO 10993-10:2010/R 2014)
Acute Systemic Toxicity (ISO 10993-11:2017)

The results of testing demonstrate that the subject device is non-cytotoxic, non-irritating, non-sensitizing, and not acutely, systemically toxic.

Physical Performance Testing:

The subject condom was tested for compliance with the ISO 23409:2011, "Male Condoms – Requirements and test methods for condoms made from synthetic materials," "Guidance for Male Condoms Made from New Material (Non-Latex), issued by the FDA in June 1995, and meets requirements of ISO 4074:2015, "Natural rubber latex male condoms – Requirements and test methods" for dimensional, tensile strength, force at break, lubricant quantity, visible defects, tear resistance and propagation, elongation, air burst volume and air burst pressure requirements.

Package Integrity:

An evaluation of seal integrity was performed on three lots (3) of the subject device according to ISO 23409: 2011 with satisfactory results.

Barrier Properties/Permeability:

A viral penetration study was performed on three (3) test lots of the subject polyurethane condom, one lot of the commercially available predicate device, and a natural rubber latex condom comparator per

Page 8

K252158
Page 4 of 4

ISO 23409: 2011. The cumulative results of the studies demonstrate the barrier effectiveness of the subject device as compared to the predicate device and natural rubber latex control condom for viral penetration under conditions of the in vitro study.

Shelf Life:

The Sagami Original 002 Polyurethane Male Condom has a shelf life based on the results of accelerated stability evaluations conducted as required in 21 CFR 801.435 and ISO 23409:2011. Based on the currently available, stability information, Mayer Labs is claiming a 5 year shelf life on Sagami Original 002 Slim Fit and Sagami Original 002 Regular, and a 3 year shelf life on Sagami Original 002 Large. All samples met predefined acceptance criteria.

Clinical In-Use Slip/Break:

Clinical testing was performed. The Study design complied with the recommendations of the FDA guidelines for clinical studies on synthetic condoms and ISO 29943 -1:2017. The Study is registered on the clinicaltrials.gov website with the identifier NCT04622306. The slippage and breakage study, which conforms to ISO 23409: 2011 and follows a protocol prepared to meet the FDA guidance "Testing Guidance for Male Condoms Made From New Material (Non-Latex)" June 1995, was conducted.

Condom Polyurethane A, representative of the Sagami Original 002 Polyurethane Male condom, met the noninferiority requirements specified in ISO 23409:2011 and demonstrated low failure rates relative to a standard natural rubber latex condom as a comparator in the full study population.

10. Conclusion

The results of the performance testing described above demonstrate that the Sagami Original 002 Polyurethane Male Condom is as safe and effective as the predicate device and supports a determination of substantial equivalence.
