Intended Use

Ultra RapidWarm™ Blast is indicated for warming of vitrified human blastocyst stage embryos.

Device Story

Ultra RapidWarm™ Blast is a single-solution reproductive medium used for warming vitrified human blastocyst stage embryos. It consists of a MOPS buffered solution containing gentamicin, human serum albumin (HSA), and sucrose. The device simplifies the warming procedure to a single step (2 minutes) compared to traditional multi-step protocols. It is supplied in gamma-sterilized 5 mL PETG bottles. The medium is used in clinical IVF laboratory settings by embryologists. By facilitating the transition of embryos from a vitrified state to a viable state for transfer, the device supports assisted reproductive technology procedures, aiming to achieve clinical pregnancy and live birth rates comparable to standard multi-step warming methods.

Clinical Evidence

Clinical evidence includes a literature review and a prospective pilot study (86 cycles) followed by a cohort study (868 cycles) conducted at a university-based IVF center. The study compared a single-step warming protocol (using the predicate as a surrogate) against the conventional multi-step protocol. Results showed comparable embryo survival (97.8%), clinical pregnancy rates (38.2% vs 39.2%), and live birth rates (28.3% vs 29.6%) for single-step versus multi-step procedures, respectively.

Technological Characteristics

Single-solution MOPS buffered medium containing gentamicin, HSA, and sucrose. Osmolality: 547 ± 20 mOsm/kg; pH: 7.30 ± 0.10. Packaging: 5 mL PETG bottles with HDPE closures. Sterilization: Aseptic filtration. Shelf-life: 9 weeks (14 days after opening). Complies with ISO 13408-1:2008/Amd1:2013, ISO 13408-2:2018, USP <71>, USP <85>, USP <791>, USP <785>, and ASTM D4169-22.

Indications for Use

Indicated for warming of vitrified human blastocyst stage embryos.

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.

Ultra RapidWarm™ Blast

The subject and predicate device have the same indications for use and intended use. The subject and predicate device have different technological characteristics, including differences in warming procedure. specifications, and shelf-life. The different technological characteristics do not raise different questions of safety and effectiveness.

# 8. Summary of Non-Clinical Performance Testing

The following studies have been performed to support substantial equivalence to the predicate device:

- Aseptic filtration and filling validation testing that met the requirements of ISO 13408-. 1:2008/Amd1:2013 and ISO 13408-2:2018.
- . Shelf-life testing was conducted to support a 9-week shelf-life for the subject device through demonstration that the product specifications (shown below) were met at time 0 and after realtime aging. Testing was also included on aged samples demonstrating that medium in bottles can maintain their specifications after 14 days of simulated use conditioning after bottle opening. Testing conducted is shown below:
- Sterility testing per USP <71> (acceptance criterion: no microbial growth) -
- Bacterial endotoxins testing per USP <85> (acceptance criterion: <0.5 EU/ml) -
- pH measurements per USP <791> (acceptance criterion: 7.30±0.10) -
- -Osmolality per USP <785> (acceptance criterion: 547±20 mOsm/kq)
- Mouse embryo assay One-cell system: ≥80% embryos developed to expanded blastocyst at -96 hours after 2 minutes of exposure.
- . Transportation testing was conducted according to ASTM D4169-22 (DC-13) and cap/seal leak testing according to USP <1207.2>.

# 9. Summary of Clinical Performance Testing

A clinical evidence summary providing information to support the safety and performance of the subject device was included in this submission. The evaluation covers literature review and data from a study on a single step warming protocol identical to the subject device. The literature review summarized research

conducted with single-step warming versus multi-step standard warming procedures, and the results showed comparable embryo survival rate, clinical pregnancy rate, and live birth rate between blastocysts warmed with the single-step and multi-step warming procedures, indicating that a single-step warming procedure is equivalent to multi-step warminq procedures. The clinical study used the Warm 1 Blast (K101003) as a surrogate for the subject device and compared the effectiveness of warming using a simplified warming protocol (2 minutes of warming in Warm 1 Blast) compared to standard warming protocol using RapidWarm Blast (K101003). The study was conducted in a universitybased IVF center in France. A prospective pilot study with 86 cycles (52 blastocysts in the control group and 42 blastocysts in the treatment group) was conducted, followed by a cohort study including 868 cycles (578 blastocysts in the control group and 336 blastocysts in the treatment group). The results from the cohort study showed that embryo survival rate after warming (97.8%), clinical pregnancy rate (38.2% vs. 39.2%), and live birth rate (28.3% vs. 29.6%) obtained with the single-step warming and with the conventional standard warming protocol, respectively, were comparable.

### 9. Conclusion

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