Device Description
Ventana's CONFIRM anti-Progesterone Receptor (1E2) Rabbit Monoclonal Primary Antibody specifically binds to progesterone receptor antigen located in the nuclear region of a variety of normal and neoplastic tissues. The antibody is diluted in 0.05 M Tris-HCl with 2% carrier protein, and 0.1% ProClin 300, a preservative. There is trace (0.2%) fetal calf serum of U.S. origin from the stock solution. Total protein concentration of the reagent is approximately 10 mg/mL. Specific antibody concentration is approximately 1 µg/mL. CONFIRM anti-PR (1E2) is a rabbit monoclonal antibody produced as a cell culture supernatant.

Description of the test set, sample size, data source, and annotation protocol
Approximately 120 negative and 216 positive cases of breast cancer, representing the clinical range of the assay, were randomly assigned to three study sites such that each site received an equal number of cases and each site received cases representing each clinical assessment category.
Summary of Performance Studies
A randomized, multi-site, multi-reader study was conducted to compare the staining performance of the CONFIRM anti-PR (1E2) on the BenchMark ULTRA instrument and on the BenchMark XT instrument to that of the Dako FLEX Monoclonal Mouse Anti-Human Progesterone Receptor Clone PgR 636 Ready-To-Use (FLEX anti-PgR (636)) on the Dako Autostainer Plus.
For CONFIRM anti-PR (1E2) staining on the BenchMark ULTRA instrument compared to the FLEX anti-PgR (636) on the Dako Autostainer Plus, the positive, negative, and overall agreement rates (pooled across all testing sites) were greater than 85%. For CONFIRM anti-PR (1E2) staining on the BenchMark XT instrument compared to the FLEX anti-PgR (636) on the Dako Autostainer Plus, the positive, negative, and overall agreement rates were all greater than 85%. For CONFIRM anti-PR (1E2) staining on the BenchMark ULTRA instrument compared to the CONFIRM anti-PR (1E2) staining on the BenchMark XT instrument, the positive, negative, and overall agreement rates were all greater than 85%.

§ 864.1860 Immunohistochemistry reagents and kits.
(a)
Identification. Immunohistochemistry test systems (IHC's) are in vitro diagnostic devices consisting of polyclonal or monoclonal antibodies labeled with directions for use and performance claims, which may be packaged with ancillary reagents in kits. Their intended use is to identify, by immunological techniques, antigens in tissues or cytologic specimens. Similar devices intended for use with flow cytometry devices are not considered IHC's.(b)
Classification of immunohistochemistry devices. (1) Class I (general controls). Except as described in paragraphs (b)(2) and (b)(3) of this section, these devices are exempt from the premarket notification requirements in part 807, subpart E of this chapter. This exemption applies to IHC's that provide the pathologist with adjunctive diagnostic information that may be incorporated into the pathologist's report, but that is not ordinarily reported to the clinician as an independent finding. These IHC's are used after the primary diagnosis of tumor (neoplasm) has been made by conventional histopathology using nonimmunologic histochemical stains, such as hematoxylin and eosin. Examples of class I IHC's are differentiation markers that are used as adjunctive tests to subclassify tumors, such as keratin.(2) Class II (special control, guidance document: “FDA Guidance for Submission of Immunohistochemistry Applications to the FDA,” Center for Devices and Radiologic Health, 1998). These IHC's are intended for the detection and/or measurement of certain target analytes in order to provide prognostic or predictive data that are not directly confirmed by routine histopathologic internal and external control specimens. These IHC's provide the pathologist with information that is ordinarily reported as independent diagnostic information to the ordering clinician, and the claims associated with these data are widely accepted and supported by valid scientific evidence. Examples of class II IHC's are those intended for semiquantitative measurement of an analyte, such as hormone receptors in breast cancer.
(3) Class III (premarket approval). IHC's intended for any use not described in paragraphs (b)(1) or (b)(2) of this section.
(c)
Date of PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the Federal Food, Drug, and Cosmetic Act is required for any device described in paragraph (b)(3) of this section before this device may be commercially distributed. See § 864.3.

| Summary of | |

| devices | CONFIRM anti-PR (1E2) is a rabbit monoclonal antibody that recognizes the A and B |
| forms of human progesterone receptor. The immunogen was developed from a | |
| synthetic peptide identified as an area of potential high antigenicity common to | |
| progesterone receptor A and B forms. The peptide was synthesized and covalently | |
| bound to keyhole limpet hemocyanin to further increase antigenicity. CONFIRM anti-PR (1E2) has been shown to react with 60 kD, 87 kD and 110 kD proteins from T47D |

| | cells via Western blotting. The protein sizes are in agreement with the predicted
molecular weight of progesterone receptor forms A, B and C.1.2 |
