Intended Use

The TPSA method for the Dimension® clinical chemistry system with the heterogeneous immunoassay module is an in vitro diagnostic test intended to quantitatively measure total prostate specific antigen (PSA) in human serum and plasma: - as an aid in the detection of prostate cancer when used in conjunction with digital rectal 1. exam (DRE) in men 50 years or older. Prostate biopsy is required for diagnosis of cancer - as an aid in management (monitoring) of prostate cancer patients. 2.

Device Story

TPSA Flex® reagent cartridge is an in vitro diagnostic immunoassay for quantitative measurement of total prostate specific antigen (PSA) in human serum and plasma. Used on Dimension® clinical chemistry systems with heterogeneous immunoassay modules. Operated by laboratory personnel in clinical settings. Device provides quantitative PSA concentration values to clinicians. Output used to aid in prostate cancer detection (in conjunction with DRE) and monitoring of diagnosed patients. Benefits include standardized laboratory assessment of PSA levels to support clinical decision-making regarding biopsy and disease management.

Clinical Evidence

No clinical data presented. Substantial equivalence is based on identical formulation, design, and manufacturing processes to the previously approved predicate device.

Technological Characteristics

In vitro immunoassay for total PSA measurement. Designed for use on Dimension® clinical chemistry systems with heterogeneous immunoassay modules. No changes to formulation or design compared to predicate.

Indications for Use

Indicated for men 50 years or older as an aid in prostate cancer detection (with DRE) and for monitoring prostate cancer patients. Prostate biopsy required for cancer diagnosis.

Regulatory Classification

Identification

A tumor-associated antigen immunological test system is a device that consists of reagents used to qualitatively or quantitatively measure, by immunochemical techniques, tumor-associated antigens in serum, plasma, urine, or other body fluids. This device is intended as an aid in monitoring patients for disease progress or response to therapy or for the detection of recurrent or residual disease.

Special Controls

*Classification.* Class II (special controls). Tumor markers must comply with the following special controls: (1) A guidance document entitled “Guidance Document for the Submission of Tumor Associated Antigen Premarket Notifications (510(k)s) to FDA,” and (2) voluntary assay performance standards issued by the National Committee on Clinical Laboratory Standards.

#### Summary of Safety and Effectiveness Information

This safety and effectiveness summary information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.

| Date of Preparation: | April 25, 2003 |
| Name of Product: | TPSA Flex® Reagent Cartridge |
| FDA Classification Name: | Total Prostate Specific Antigen for the detection and<br>management of prostate cancer |
| Predicate Device: | Dade Behring TPSA Flex® reagent cartridge (P000021/S2) |

Intended Use: The TPSA method for the Dimension® clinical chemistry system with the heterogeneous immunoassay module is an in vitro diagnostic test intended to quantitatively measure total prostate specific antigen (PSA) in human serum and plasma:

- as an aid in the detection of prostate cancer when used in conjunction with digital rectal 1. exam (DRE) in men 50 years or older. Prostate biopsy is required for diagnosis of cancer
- as an aid in management (monitoring) of prostate cancer patients. 2.

#### Comparison to Predicate Device:

The TPSA Flex® reagent cartridge with the labeling revision referenced in this submission is substantially equivalent in intended use, principle and performance to the current Dade Behring Total Prostate Specific Antigen assay (P000021/S2). Both assays are in vitro immunoassays with intended uses for the measurement of Prostate Specific Antigen in serum and plasma.

There are no formulation or design changes associated with this labeling change. The two products are identical and use the same manufacturing processes. When the TPSA Flex® reagent cartridge product (P000021/S2) was approved by the FDA, the insert sheet stated to use the TPSA Calibrator, RC 459, in the US and T/F PSA Calibrator, RC 452, outside the US. Both RC 459 and RC 452 have the same formulation but different packaging and labeling. We created two separate calibrator products at the FDA's request since we did not have approval for the Free PSA FLex® at the time we initiated sale of the Total PSA Flex®. We now have approval for the Free PSA product and intend to revise the Total PSA Flex® insert sheet to remove reference to the TPSA Calibrator, RC459. This latter product will no longer be available for sale.

{1}------------------------------------------------

Conclusion: The revised PSA Flex® reagent cartridge is substantially equivalent in principle and performance to the current PSA Flex® reagent cartridge.
