5.15 Substantial Equivale

Intended Use

The intended use of the Duet™ System is expanded to include the detection and quantification of chromosome 17 and the HER-2/neu gene via fluorescence in situ hybridization (FISH) in human breast cancer tissue specimens, probed by the Vysis® PathVysion™ HER-2 DNA Probe Kit (the PathVysion™ Kit). The Duet™ is to be used as an adjunctive automated enumeration tool, in conjunction with manual visualization, to assist in determining HER-2/neu gene to chromosome 17 signal ratio. Besides the additional indication, the Intended Use and Indication for Use statement of the Duet™ System were not changed.

Detection, classification and counting of HER-2/neu gene amplification via fluorescence in situ hybridization (FISH) in human breast cancer tissue specimens, probed by the PathVysion™ Kit, are routinely performed manually at the specialized laboratories using conventional microscopes, according to the instructions provided with the approved kit. The claim of an automated aiding tool for the detection and enumeration of FISH signals is also claimed by the 510(k)-cleared automatic enumeration predicate devices, the Vysis® AutoVysion™ System, the Ariol® HER-2/neu FISH and the previously cleared Duet™ System. Both the Vysis AutoVysion™ System and the Ariol® HER-2/neu FISH, similar to the Duet™ System, are intended for in vitro diagnostic use as an aid to the pathologist in the detection, classification, and counting of cells of interest based on particular color, intensity, size, pattern, and shape. In particular, the specific indication of HER-2/neu gene amplification detection via fluorescence in situ hybridization (FISH) in formalin-fixed, paraffin-embedded human breast cancer tissue specimens, probed by the PathVysion™ Kit, is common to the Duet™ System and to both these predicates.

The new intended use was supported by a comparative performance study demonstrating that the operation of the Duet™ System is safe and effective for this application in comparison to manual microscopy. This study, which is summarized below, further confirms that any minor differences between the manual and the automated Duet™ System do not raise any issue of safety or efficacy.

Technological Characteristics and Mode of Operation

The current Duet™ System is the same system as the 510(k)-cleared Duet™ System. No change was required to be incorporated to the system's hardware to support the new indication, and only minor software changes, including new algorithm for the automatic calculation of the overall amplification ratio of HER-2/neu gene, were made. All these changes were fully verified and validated through software verification and validation. The performance study described below

further confirms that any minor differences between the manual and the automated Duet™ System do not raise any issue of safety or efficacy.

5.16 Performance Characteristics of the Duet™ System:

A performance evaluation study was performed in order to evaluate the performance of the Duet™ System for the detection of amplification of the HER-2/neu gene via FISH in human breast cancer tissue specimens, probed by the PathVysion™ Kit, in terms of its accuracy in comparison to the manual system, and its reproducibility and repeatability.

The performance evaluation study report is comprised of the following four studies, which are summarized below:

Study 1 - Methods Comparison - a comparison of the Duet™ System method to manual scoring method.

Study 2 - Precision/Reproducibility Performance - an evaluation of the performance of the Duet™ System in terms of reproducibility and repeatability, within a system and across systems.

Study 3 - The Optimal Number of Fields of View - a determination of the optimal number of Fields of View required to be captured by the system for accurate sampling of the specimen.

Study 4 - Methods Comparison at the Borderline Range. A comparison of the Duet™ System method to manual scoring method at the borderline range.

5.16.1 Methods Comparison with Predicate Device

The purpose of this study was to demonstrate the accuracy of the Duet™ System method for detection of amplification of the HER-2/neu gene via fluorescence in situ hybridization (FISH) in human breast cancer tissue specimens, probed by the PathVysion™ Kit, in comparison to the manual scoring method.

The study was conducted in four (4) sites, which followed the same study protocol. A total of 56 specimen slides, prepared from human breast cancer tissue specimens in various stages of the disease, representing the entire intended use population, were probed by the PathVysion™ Kit according to the manufacturer instructions. Each slide was screened both manually and using the Duet™ system.

For the purpose of the agreement analysis between the manual and the Duet™ System, 'Amplification' scoring ("FISH positive") was defined as a ratio of ≥ 2.0 and 'No-Amplification' scoring (FISH negative'') was

5

d as a ratio of 2.3). All slides were prepared according to the probe manufacturer's instructions.

The statistical analyses performed include estimating the average value, standard deviation and percent coefficient of variation (CV) for each slide separately for repeatability, lab reproducibility and day reproducibility.

Test results obtained for three (3) FOVs analysis demonstrated that CV values were usually low and ranged between 0.56 and 12.90 % for all cases. Only one exception was seen is laboratory reproducibility for one of the sample with a CV of 31.92%, resulted from very high amplification, which avoided accurate spot counting. Considering this objective problem of accuracy, good repeatability and reproducibility for the Duet™ System was demonstrated.

Therefore it can be concluded that the Duet™ System was proven to have high values of repeatability within run, between days and between sites, for three (3) FOVs analyses.

5.16.3 The Optimal Number of Fields of View

Method comparison studies and reproducibility and repeatability studies were conducted using both 3 and 6 FOVs to evaluate the optimal performance of the Duet System using a minimal number of FOVs. The correlation between results obtained from the Duet System 3 and 6 FOV analyses revealed a correlation of .996, with R-square = .993. In addition, the constant was near 0 (0.0084) and non-significant (t = 0.207, p = 0.836). Therefore, 3 FOV provides results that are sufficient for the effective performance of the Duet System.

5.16.4 Methods Comparison at the Borderline Range

The purpose of this study was to further demonstrate the accuracy of the Duet™ System method for detection of amplification of the HER-2/neu gene via fluorescence in situ hybridization (FISH) in human oreast cancer tissue specimens, probed by the PathVysion™ Kit, in comparison to the manual scoring method, in the borderline range.

For this purpose, a total of 21 human breast cancer tissue specimen slides, representing a borderline range [1.5-2.5], were selected,

7

including the seven (7) borderline samples of this range from Study-1 and additional new fourteen (14) borderline samples collected from additional site.

A combined analysis of these results with the results of the seven (7) borderline samples from Study-1 was performed. All slides used for the analysis were human clinical specimens prepared from breast cancer tissues, probed by the PathVysion™ Kit according to the manufacturer instructions and which were found to be in the predefined borderline range [1.5-2.5].

For the purpose of the analysis of the agreement between the manual and the Duet™ System, the same criteria used in Study-1 (Method Comparison) were used. Thus, 'Amplification' scoring ("FISH positive") was defined as a ratio of ≥ 2.0 and 'No-Amplification' scoring ("FISH negative") was defined as a ratio of
