Indications for Use

P-1 is intended for assisted reproductive procedures that involve the manipulation of gametes and embryos. These procedures include the use of P-1 as a culture medium through day three of growth.

Device Story

P-1 Medium is a synthetic, defined culture medium for in vitro embryo development. It supports early embryonic growth up to three days post-fertilization. Formulated without glucose and phosphate to optimize blastocyst development. Used in clinical settings by embryologists/technicians during assisted reproductive technology (ART) procedures. Oocytes are placed in culture dishes with P-1 and protein supplementation; fertilization occurs; zygotes are transferred to fresh P-1 medium and incubated in CO2. The medium provides a controlled environment for early development before embryo transfer or transition to a more complex medium. Benefits include standardized, defined conditions for human embryo culture.

Clinical Evidence

No clinical data. Performance is supported by mouse embryo assay (MEA) to ensure functionality and absence of toxic components, alongside endotoxin and sterility testing. Historical use in clinical settings is cited as evidence of suitability.

Technological Characteristics

Synthetic, defined medium composed of salts and nutrients. Formulated without glucose and phosphate. Supports in vitro embryo development up to day three. Requires protein supplementation. Subject to lot-specific release testing including mouse embryo assay, endotoxin testing, and sterility testing.

Indications for Use

Indicated for use in assisted reproductive technology procedures involving the manipulation of gametes or embryos, specifically as a culture medium for embryo development up to day three.

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.

#### Device Identification:

| Trade Name: | P-1® (Preimplantation Stage One) Medium |
|----------------------|-----------------------------------------|
| Common Name: | In vitro embryo culture medium |
| Classification Name: | Reproductive Media (21 CFR, 886.6180) |

#### Predicate Device:

Notice of Final Rule, 63 FR 48428, Docket number 97N-0335

### Description:

P-1 medium is a synthetic, defined medium composed of a balanced mixture of salts and other nutrient substances designed to support early stages of embryonic growth (up to three days post-fertilization). P-1 has been formulated without glucose and phosphate, which may be detrimental to blastocyst development. P-1 may be used as a stand-alone medium, or as the first stage of a sequential medium protocol.

October 9, 1998

### Intended Use:

P-1 is intended for assisted reproductive procedures that involve the manipulation of gametes and embryos. These procedures include the use of P-1 as a culture medium through day three of growth.

# Technological Characteristics:

After retrieval of oocytes from the patient, the oocytes are placed in a culture dish containing P-1 medium and the desired type and amount of protein supplementation. Fertilization is allowed to take place, and the zygote is removed to a fresh dish containing fresh P-1 medium and protein. This culture dish is placed into a carbon dioxide incubator, and the embryo is allowed to develop, in vitro, until the desired stage of development has been achieved, usually up to three days post fertilization. At that time, the embryo may be transferred to the patient, or to a second, more complex medium for continued growth.

### Performance Data:

P-1 is assayed by mouse embryo assay prior to release to market. This assay assures that the product is both functional for its intended use, the support of embryonic growth, and that no toxic components are present in the formulation. P-1 has been used in a variety of clinical settings, for its intended use, for a number of years. In that time, the product has become the standard media used for the early development of human embryos in vitro.

# Additional Information:

Mouse embryo testing will be performed as a condition of release for these products, as well as endotoxin and sterility testing. Results of all release assays performed will be reported on a lot-specific certificate of analysis, and will be indicated on the labeling.

{2}------------------------------------------------

# Conclusion:

The conclusion from performance testing, as well as a review of the historical information contained in professional literature shows that P-1 is suitable for its intended use, and meet the criteria outlined in the Notice of Final Rule, 63 FR 48428, Docket number 97N-0335.
