#### III. Predicate Device

INVOcell Intravaginal Culture System (DEN150008) from INVO Bioscience, Inc.

The predicate device has not been subject to a design-related recall.

#### IV. Description of the Device

The INVOcell Intravaginal Culture System consists of the INVOcell Culture Device and the INVOcell Retention Device.

The INVOcell Culture Device is a radiation sterilized, single-use polystyrene container that holds and maintains the gametes and/or embryos during intravaginal culture for a maximum duration of 120 hours. The INVOcell Culture Device consists of three components: Inner Vessel, Outer Rigid Shell, and Retention Device.

The Inner Vessel holds the culture medium along with the gametes and /or embryos. It has a rotating valve at its top, which allows for access to the chamber when loading and retrieving gametes/embryos and provides a seal during incubation. At the bottom of the Inner Vessel, there is a physical stop to limit the penetration depth of the retrieval catheter into the Inner Vessel to protect embryos during retrieval.

The Outer Rigid Shell that is made of polystyrene, protects the Inner Vessel from the vaginal environment when the device is in use. The Inner Vessel fits into the bottom portion of the Outer Rigid Shell and is sealed in position by the top portion of the Outer Rigid Shell cap with a silicone O-ring, which provides a liquid-tight seal to prevent contamination of the Inner Vessel.

#### V. Summary of Non-Clinical Performance Testing

The following non-clinical performance testing was conducted on the INVOcell Culture Device:

- Shelf-Life Testing – The following testing was conducted following real-time aging in support of the six-year device shelf-life:
- Mouse Embryo Assay (MEA) per the 2021 FDA guidance Mouse Embryo Assay for Assisted o Reproduction Technology Devices: 1-Cell MEA: ≥80% embryos developed to expanded blastocyst at 120h.
- Seal Integrity Testing: No contamination inside and outside the vessel after 120h of O incubation.
- o pH Stability: pH of test medium in device remained within the specified range after 120h of incubation.
- Vessel Wall Optical Clarity: No obscured views after 120h of incubation. O
- Sterilization Validation – The gamma irradiation sterilization methods for the predicate device (ISO 11137:2006) are being relied on in support of this submission.
- Packaging Integrity Testing was conducted after accelerated aging. Testing included bubble leak testing (ASTM F2096) and seal strength testing (ASTM F88) on the INVOcell packaging to qualify the 6-year expiration date.

#### VII. Summary of Clinical Performance Testing

Two clinical studies were conducted to support extension of the culture duration to 120 hours, the revised culture conditions, and substantial equivalence to the predicate device. A summary of the two studies are shown below:

# Study 1: INVOcell Culture System Comfort and Retention

This was a single center, open label trial to evaluate Comfort and Retention of the INVOcell Intravaginal Culture System during 120 hours of intravaginal incubation. After device removal and final speculum exam, study participants also completed a questionnaire to assess their discomfort, device expulsion, or incidence of vaginal discharge, spotting, or itching during the 5-day use of the subject device. There were no reports of INVOcell Culture Device expulsion in the 29 subjects evaluated. One subject reported the system was felt to be dislodged and the subject successfully readjusted the device to maintain the system in place. This results in an overall retention rate of 96%, which demonstrated the INVOcell Retention Device performed as intended.

There were no clinically relevant vaginal findings (e.g., lesions, ulcerations, erythema, or bleeding) identified after device wearing for 120 hours. These results demonstrated the safety of wearing the device for the longer 120 hour duration.

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

# Study #2: Retrospective Analysis of the INVOcell Culture System (IVC) in Comparison with traditional IVF and ICSI for 5 Day Incubation

This was a multicenter, retrospective cohort study that compared safety and effectiveness of the INVOcell Culture System (IVC/IVF and IVC/ICSI) to traditional IVF and ICSI procedures for 5 Day incubation. The study provided real-world evidence to support the expanded indication to 120h incubation and use of the revised device loading procedure, including a lower medium volume and a mineral oil overlay. Data was collected from four fertility clinics in the U.S. for the 3-year period of January 2017 to December 2019.

The data collection effort was focused on evaluating the outcomes of INVOcell day 5 transfer (IVC/IVF and IVC/ICSI) compared to historical outcomes of INVOcell day 3 transfer (IVC/IVF and IVC/ICSI). Rates of embryo development to the designated stage were also examined after day 5 incubation.

The four sites contributed a total of 240 fresh embryo transfers in the INVOcell arm (IVC/IVF and IVC/ICSI) and 685 fresh embryo transfers in the traditional IVF and ICSI arm. Patient demographics and fertility diagnoses were comparable between both cohorts.

# Effectiveness

When comparing the data of day 3 INVOcell (IVC/IVF and IVC/ICSI) using the original loading procedure to day 5 INVOcell (IVC/IVF and IVC/ICSI), which used the revised loading methods, the day 5 embryo development is more advanced, and the clinical pregnancy and live birth rates are higher for day 5 incubation in the INVOcell device for both IVF and ICSI cohorts.

While the INVOcell ICSI (IVC/ICSI) method produced lower rates of embryos developed to the blastocyst stage than traditional ICSI produced, the rates of embryos developed to the blastocyst stage using the IVC/IVF and traditional IVF methods were similar. The rates of embryo transfer, clinical pregnancy, implantation, miscarriage, live birth, and pre-term birth using the IVC/ICSI methods were similar to the day 5 traditional IVF and ICSI methods. The data supports that embryos suitable for transfer can be formed by incubation in the INVOcell device with 120h incubation and use of the revised device loading methods.

# Safety

The type of maternal and offspring adverse events experienced in both the IVC (IVF and ICSI) cohort and traditional IVF and ICSI cohort were similar. There were a total of 2 birth defects reported in 2 subjects in the IVC (IVF and ISCI) cohort (out of 104 births with known outcomes) and 9 birth defect in 9 subjects in the traditional IVF and ICSI cohort (out of 273 births with known outcomes). The data supports that incubation in the INVOcell device with 120h incubation and use of the revised device loading methods did not result in increased adverse events or outcomes.

#### VIII. Conclusion

The results of the performance testing described above demonstrate that INVOcell Culture System is as safe and effective as the predicate device and supports a determination of substantial equivalence.
