{0}------------------------------------------------ # DEC 1. 2 2003 #### 8. 510(k) SUMMARY This summary of safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92. The Assigned 510(k) number is _ K 033299 ## Submitter: ACON Laboratories, Inc. 4108 Sorrento Valley Boulevard San Diego, California 92121 Tel.: 858-535-2030 Fax: 858-535-2038 #### Date: October 7, 2003 ## Contact Person: Edward Tung, Ph.D. ## Product Names: ACON® mAMP-500 One Step Methamphetamine Test Strip ACON® mAMP-500 One Step Methamphetamine Test Device #### Common Name: Immunochromatographic test for the qualitative detection of Methamphetamine in urine. ## Regulation Name: Methamphetamine test system. ## Product Code: LAF {1}------------------------------------------------ ## Classification Number: 21 CFR, 862.3610 #### Device Classification: The Methamphetamine test systems have been classified as Class II devices with moderate complexity. The ACON mAMP-500 One Step Methamphetamine Test Strip and ACON mAMP-500 One Step Methamphetamine Test Device are similar to another FDA-cleared device for the qualitative detection of Methamphetamine in urine specimens. 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 GC/MS analysis. #### Intended Use: The ACON mAMP-500 One Step Methamphetamine Test Strip and ACON mAMP-500 One Step Methamphetamine Test Device are rapid chromatographic immunoassays for the qualitative detection of Methamphetamine in urine at a cutoff concentration of 500 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 GC/MS analysis. They are intended for healthcare professionals including professionals at point-of-care sites. #### Description: The ACON mAMP-500 One Step Methamphetamine Test Strip and ACON mAMP-500 One Step Methamphetamine Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative screening of Methamphetamine in a urine sample. The test is based on the principle of antibody immunochemistry. It utilizes the mouse monoclonal antibody to selectively detect elevated levels of Methamphetamine and its metabolite in urine at a cutoff concentration of 500 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 Methamphetamine at the concentration i 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. ## Comparison to a Predicate Device: A comparison of the features of the ACON mAMP-500 One Step Methamphetamine Test Strip and ACON mAMP-500 One Step Methamphetamine Test Device versus a FDA-cleared Methamphetamine test with 500 ng/mL Methamphetamine cutoff is shown below: {2}------------------------------------------------ - Both tests are assays intended for the qualitative detection of Methamphetamine in urine . samples. - Both tests are intended as a screening method that provides a preliminary analytical test ● result. - Both tests are immunochromatographic, lateral flow assays for the rapid detection of . Methamphetamine with a visual, qualitative end result. - Both tests utilize the same basic immunoassay principles that rely on antigen/ antibody . interactions to indicate a positive or negative result. - Both tests have a cutoff Methamphetamine concentration of 500 ng/mL. . #### Safety and Effectiveness Data: #### Accuracy A clinical evaluation was conducted using 300 clinical urine specimens including approximately 10% of the specimens containing Methamphetamine concentration fell between -25% cutoff to +25% cutoff range. This evaluation compared the test results between ACON mAMP-500 One Step Methamphetamine Test Strip and ACON mAMP-500 One Step Methamphetamine Test Device with a FDA-cleared Methamphetamine test; as well as compared against data obtained from the customary Gas Chromatography/Mass Spectrometry analysis. These comparisons of data yielded the following results: #### ACON mAMP-500 One Step Methamphetamine Test Strip versus a FDA-cleared mAMP 500 Test: Positive Agreement: 108 / 108 =>99% (97 % - 100 %*) Negative Agreement: 153 / 192 = 80% (73 % = 85%*) Overall Agreement: 261 / 300 = 87% (83 % - 91 %*) * 95% confidence intervals #### ACON mAMP-500 One Step Methamphetamine Test Device versus a FDA-cleared mAMP 500 Test: Positive Agreement: 108 / 108= 100% (97 % - 100 %*) Negative Agreement: 158 / 192= 82% (76 % - 87 %*) Overall Agreement: 266 / 300 = 89% (84 % - 92 %*) * 95% confidence intervals {3}------------------------------------------------ ACON mAMP-500 One Step Methamphetamine Test Strip versus data obtained with GC/MS at the cutoff concentration of 500 ng/mL: | | | Specimen Cutoff Range by GC/MS Data | | | | % Agreement with<br>GC/MS Data | | |-----------------------------------|----------|-------------------------------------|------------------|-------------------|-------------------|--------------------------------|---------------------------------| | | | Negative | < -25%<br>Cutoff | -25% to<br>Cutoff | Cutoff to<br>+25% | > +25%<br>Cutoff | | | ACON<br>mAMP<br>500 Test<br>Strip | Positive | 0 | 0 | 7 | 8 | 132 | 100% (140/140)<br>(97% - 100%)* | | | Negative | 150 | 0 | 3 | 0 | 0 | 97% (153/160)<br>(91% - 98%)* | # ACON mAMP-500 One Step Methamphetamine Test Strip versus GC/MS Total agreement with GC/MS : 293/300 = 98% (95%- 99%)* * Denotes 95% confidence intervals. #### ACON mAMP-500 One Step Methamphetamine Test Device versus GC/MS | | | Specimen Cut off Range by GC/MS Data | | | | % Agreement with GC/MS Data | | |---------------------------------|----------|--------------------------------------|--------------|----------------|----------------|-----------------------------|-------------------------------| | | | Negative | <-25% Cutoff | -25% to Cutoff | Cutoff to +25% | >+25% Cutoff | | | ACON<br>mAMP-500<br>Test Device | Positive | 0 | 0 | 4 | 8 | 131 | 99% (139/140)<br>(96% - 99%)* | | ACON<br>mAMP-500<br>Test Device | Negative | 150 | 0 | 6 | 0 | 1 | 98% (156/160)<br>(94% - 99%)* | Total agreement with GC/MS : 295/300 = 98% (96% - 99%)* * Denotes 95% confidence interval. #### Performance Characteristics and Other information: The performance characteristics of ACON mAMP-500 One Step Methamphetamine Test Strip, ACON mAMP-500 One Step Methamphetamine 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 mAMP-500 One Step Methamphetamine Test Strip, ACON mAMP-500 One Step Methamphetamine Test Device and a FDA-cleared Methamphetamine test with the same Methamphetamine cutoff concentration. It is also demonstrated that these tests are safe and effective in qualitatively detecting Methamphetamine at a concentration of 500 ng/mL. The POL study demonstrated that these tests are suitable for healthcare professionals including professionals at point-of-care sites. {4}------------------------------------------------ Image /page/4/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
