Device Story

CryoX™ Vitrification Freeze/Thaw Kit consists of specialized media solutions for cryopreservation of human oocytes and embryos. Freeze Kit uses two sequential solutions to dehydrate samples before rapid cooling in liquid nitrogen; Thaw Kit uses three sequential solutions to rehydrate samples. Solutions contain Medium 199 (M199), human serum albumin (HSA), gentamicin sulfate, and varying concentrations of cryoprotectants (DMSO, ethylene glycol, sucrose). Used in clinical embryology laboratories by trained professionals. Output is preserved or thawed viable oocytes/embryos for use in assisted reproductive technology (ART) procedures. Benefits include enabling storage of reproductive cells for future fertility treatments.

Clinical Evidence

No clinical data. Bench testing only. Performance supported by aseptic filtration validation (ISO 13408), shelf-life/stability testing (ASTM F1980), transportation testing (ASTM D4169), and Mouse Embryo Assay (MEA) showing ≥ 80% development to expanded blastocyst at 96 hours.

Technological Characteristics

Media-based reproductive supplement. Components: M199, HSA, gentamicin sulfate, DMSO, ethylene glycol, sucrose. pH 7.2-7.6. Aseptic filtration sterilization. Single-use 4.5 mL PETG vials. Shelf-life 6 months at 2-8°C. Standards: ISO 13408-1/2, USP <791> (pH), USP <785> (osmolality), USP <71> (sterility), USP <85> (endotoxin), ASTM F1980-16 (aging), ASTM D4169-22 (transport).

Indications for Use

Indicated for vitrification and thawing of human oocytes (MII), pronuclear (PN) zygotes, day 3 cleavage stage embryos, and blastocyst stage embryos. Prescription use only.

Regulatory Classification

Identification

Reproductive media and supplement are products that are used for assisted reproduction procedures. Media include liquid and powder versions of various substances that come in direct physical contact with human gametes or embryos (including water, acid solutions used to treat gametes or embryos, rinsing solutions, sperm separation media, supplements, or oil used to cover the media) for the purposes of preparation, maintenance, transfer or storage. Supplements are specific reagents added to media to enhance specific properties of the media (e.g., proteins, sera, antibiotics, etc.).

Special Controls

*Classification.* Class II (special controls) (mouse embryo assay information, endotoxin testing, sterilization validation, design specifications, labeling requirements, biocompatibility testing, and clinical testing). The device, when it is phosphate-buffered saline used for washing, and short-term handling and manipulation of gametes and embryos; culture oil used as an overlay for culture media containing gametes and embryos; and water for assisted reproduction applications, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 884.9.

However, as stated in the table, the differences in indications for use do not represent a new intended use and the differences in technological characteristics do not raise different questions of safety and effectiveness.

#### SUMMARY OF NON-CLINICAL PERFORMANCE TESTING VII.

The following studies have been conducted in support of the substantial equivalence to the predicate device.

- Aseptic filtration and aseptic filling validation, per ISO 13408- 1:2008 & A1:2013 and ISO . 13408-2:2018.

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

- . Shelf-life testing was conducted to support a 6-month shelf-life for the subject device through demonstration that the product specifications (shown below) were met at time 0 and after accelerated aging in accordance with ASTM F1980- 16:
- A Appearance: Clean, transparent, pink; no impurities
- > pH per USP < 791> : 7.2-7.6
- > Osmolality per USP <785>: 855~1042 mOsmoVkg for ES (1:2 dilution); 1916-2477 mOsmoVkg for VS (1:2 dilution); 1653~2430 mOsmoVkg for TS; 871~1025 mOsmoVkg for DS; 307-318 mOsmol/kg for WS
- A Sterility per USP < 71>: No microbial growth
- > Bacterial endotoxin per USP <85>: < 0.5 EU/mL
- > MEA per the 2021 FDA guidance Mouse Embryo Assay for Assisted Reproduction Technology Devices: 1-Cell MEA: > 80%embryos developed to expanded blastocyst at 96 hours.
- . Transportation testing per ASTM D4169-22 and cap/seal leak testing using a method equivalent to USP < 1207.2> on transportation-conditioned devices.

#### CONCLUSION VIII.

The results of the performance testing described above demonstrate that CryoX™ Vitrification Freeze Kit / Thaw Kt is as safe and effective as the predicate device and supports a determination of substantial equivalence.
