## Indications for Use

The ACON BUP One Step Buprenorphine Test Strip and ACON BUP One Step Buprenorphine Test Device are rapid chromatographic immunoassays for the qualitative detection of Buprenorphine in urine at a cutoff concentration of 10 ng/mL. These tests are used to provide only a preliminary analytical result. All positive test results obtained with these devices must be confirmed by another test method, preferably LC/MS analysis. They are intended for use by healthcare professionals including professionals at point-of-care sites to assist in the determination of drug compliance.

## Device Story

Rapid chromatographic immunoassay for qualitative Buprenorphine detection in human urine; utilizes competitive binding lateral flow principle with mouse monoclonal antibodies. Input: urine sample; Output: visual colored-line in test region (negative result) or absence of line (positive result). Procedural control line confirms proper wicking. Used at point-of-care sites by healthcare professionals. No instrumentation required. Results are preliminary; require confirmation via LC/MS. Assists clinicians in assessing patient drug compliance.

## Clinical Evidence

Clinical evaluation of 226 urine specimens compared subject devices against an FDA-cleared test and LC/MS. Results showed 95% overall agreement with the FDA-cleared test (84% positive agreement, 99% negative agreement). Comparison against LC/MS yielded 99.6% total agreement (98-99% 95% CI).

## Technological Characteristics

Lateral flow immunochromatographic assay; competitive binding principle; mouse monoclonal antibody-based detection; 10 ng/mL cutoff; visual readout; no instrumentation required; standalone test strip or device format.

## Regulatory Identification

An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.

## Special Controls

*Classification.* Class II (special controls). An opiate test system is not exempt if it is intended for any use other than employment or insurance testing or is intended for Federal drug testing programs. The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing, and does not include devices intended for Federal drug testing programs (*e.g.,* programs run by the Substance Abuse and Mental Health Services Administration (SAMHSA), the Department of Transportation (DOT), and the U.S. military).

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

# Classification Number:

#### 21 CFR, 862.3650

#### Device Classification:

The Buprenorphine test systems have been classified as Class II devices with moderate complexity. These tests are used to provide only a preliminary analytical result. All positive test results obtained with these devices must be confirmed by another test method, preferably LC/MS analysis.

#### Intended Use:

The ACON BUP One Step Buprenorphine Test Strip and ACON BUP One Step Buprenorphine Test Device are rapid chromatographic immunoassays for the qualitative detection of Buprenorphine in urine at a cutoff concentration of 10 ng/mL. These tests are used to provide only a preliminary analytical result. All positive test results obtained with these devices must be confirmed by another test method, preferably LC/MS analysis. They are intended for use by healthcare professionals including professionals at point-of-care sites to assist in the determination of drug compliance.

# Description:

The ACON BUP One Step Buprenorphine Test Strip and the ACON BUP One Step Buprenorphine Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative screening of Buprenorphine in a urine sample. The test is based on the principle of antigen-antibody immunochemistry. It utilizes the mouse monoclonal antibody to selectively detect elevated levels of Buprenorphine in urine at a cutoff concentration of 10 ng/mL. These tests can be performed without the use of an instrument.

A drug-positive urine specimen will not generate a colored-line in the designated test region, while a negative urine specimen or a urine specimen containing Buprenorphine at the concentration below the cutoff level will generate a colored-line in the test region. To serve as a procedural control, a colored-line should always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

#### Safety and Effectiveness Data:

#### Accuracy

A clinical evaluation was conducted using 226 clinical urine specimens including approximately 10% of the specimens containing Buprenorphine concentration fell between -25% cutoff to +25% cutoff range. This evaluation compared the test results between ACON BUP One Step Buprenorphine Test Strip and ACON BUP One Step Buprenorphine Test Device with a FDAcleared Buprenorphine test; as well as compared against data obtained from the customary

#### Performance Characteristics and Other information:

The performance characteristics of the ACON BUP One Step Buprenorphine Test Strip and the ACON BUP One Step Buprenorphine Test Device were verified by analytical sensitivity study, specificity and cross reactivity study, interference studies, precision study, read time flex study, temperature flex study, specimen storage and stability study. Study results indicate that these test devices are robust and can perform satisfactorily when used according to the "Indication for Use" statement specified in their package inserts.

#### Conclusion:

These clinical studies demonstrated substantial equivalency on performance between the ACON BUP One Step Buprenorphine Test Strip, the ACON BUP One Step Buprenorphine Test Device and a FDA-cleared Buprenorphine test with the same Buprenorphine cutoff concentration. It is also demonstrated that these tests are safe and effective in qualitatively detecting Buprenorphine at a concentration of 10 ng/mL. The POL study demonstrated that these tests are suitable for healthcare professionals including professionals at point-of-care sites.
