Intended Use

GM501 Wash is intended for in vitro procedures involving handling and micromanipulation of human occytes and embryos outside of a CO> incubator. Include oocyte and embryo washing (e.g. after oocyte aspiration, after hyaluronidase treatment to remove cumulus cells, before and after cryopreservation, and before embryo transfer) and micromanipulation procedures (e.g. assisted hatching). GM501 Wash is not intended for use in transferring embryos into the uterine cavity.

Device Story

GM501 Wash is a ready-to-use solution for handling/micromanipulation of human oocytes and embryos outside CO2 incubators; used during ART procedures like washing post-aspiration, post-hyaluronidase treatment, pre/post-cryopreservation, and pre-transfer. Aseptically filled in sterilized bottles; shelf-life 6 months; stable 7 days post-opening. Clinicians use the solution to maintain optimal conditions for oocytes/embryos during benchtop procedures. Output is a treated/washed biological sample; facilitates safe handling and micromanipulation; benefits patient by supporting embryo viability during necessary laboratory steps.

Clinical Evidence

Bench testing only. Studies included pH, osmolality, sterility (USP <71>), endotoxin (USP <85>), and Mouse Embryo Assay (MEA). MEA demonstrated ≥80% blastocyst development at 96h following 1h exposure. Shelf-life and post-opening stability testing confirmed specifications met over 6 months and 7 days, respectively.

Technological Characteristics

Aqueous solution containing salts (NaCl, KCl, MgSO4, CaCl2), glucose, amino acids, HEPES, HSA, and pyruvate. Sterilized via aseptic filtration per ANSI/AAMI/ISO 13408-1:2008(R)2011 and 13408-2:2003(R)2013. Osmolality 270-290 mOsm/kg; pH 7.2-7.5. Packaged in 20, 50, 500 ml bottles.

Indications for Use

Indicated for in vitro handling and micromanipulation of human oocytes and embryos outside of CO2 incubator, including washing and assisted hatching. Not indicated for uterine embryo transfer.

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.

Indications include oocyte and embryo washing (e.g. after oocyte aspiration, after hyaluronidase treatment to remove cumulus cells, before and after cryopreservation, and before embryo transfer) and micromanipulation procedures (e.g. assisted hatching). GM501 Wash is not intended for use in transferring embryos into the uterine cavity. | Oocyte and embryo washing, manipulation, fertilization by intracytoplasmic sperm injection (ICSI), embryo transfer. | Different: Both devices are indicated for washing, handling, and manipulation of oocytes and embryos. The predicate device has additional uses beyond the subject device including sperm washing, ICSI, and embryo transfer.

In addition, the two media products have similarities in specifications (pH, osmolality, sterility, etc.) and sterilization methods. However, differences exist in media formulation, endotoxin and MEA specifications, and shelf-life duration for the different media products. As discussed in the table above, these differences do not raise different questions of safety and effectiveness as compared to the predicate device, and can be assessed through performance data. ## Summary on Non-Clinical Performance Testing: The following studies have been performed to support substantial equivalence to the predicate device: - pH testing (acceptance criterion: 7.2-7.5) ● - Osmolality testing (acceptance criterion: 270-290 mOsm/kg) - Aseptic filling validation per ANSI/AAMI/ISO 13408-1:2008(R)2011, ANSI/AAMI/ISO 13408-. 2:2003(R)2013, and the FDA's "Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing - Current Good Manufacturing Practice." - . Sterility testing per USP <71> (acceptance criterion: no growth) - Bacterial endotoxins testing per USP <85> (acceptance criterion: <0.25 EU/ml) ● - Mouse Embryo Assay (MEA) using established protocol: One-cell mouse embryos were exposed to GM501 Wash for one hour to represent the worst-case exposure for this short-term use medium. The embryos were transferred to culture medium and cultured at 37°C in an atmosphere containing 5% CO2. The percentage of embryos developed to the blastocyst stage within 96 hours were assessed in comparison with the control group. The acceptance specification is ">80% blastocysts at 96h following a 1h exposure to GM501 Wash." {6}------------------------------------------------ - Shelf-life testing was conducted to ensure that device specifications for the following parameters are met at time zero and at the end of shelf-life (6 months): pH, osmolality, sterility, 1-cell MEA, and endotoxin - Stability testing after bottle opening was conducted to ensure that device specifications for the following parameters are met seven days after opening of bottles: pH, osmolality, sterility, 1-cell MEA, and endotoxin. ### Conclusion: The subject and predicate devices have the same intended use and comparable technological characteristics. The differences in technological characteristics between the subject and predicate devices do not raise different questions of safety and effectiveness. The performance data demonstrate that the subject device is substantially equivalent to the predicate device.
