## Indications for Use

The Easy pain Supreme Self Monitoring Blood Glucose Test System is used by individuals with diabetes. It is for the quantitative measurement of glucose levels in fresh capillary whole blood, as an aid in monitoring the effectiveness of diabetes management in the home and in clinical settings.

## Device Story

System comprises meter, test strips, auto-lancet, check strip, code card, and control solution. User applies fresh capillary whole blood to disposable test strip; glucose oxidase enzyme catalyzes oxidation of glucose to gluconic acid. Mediator transfers electrons to carbon electrode, generating current proportional to glucose concentration. Meter measures current and displays result after 25 seconds. Used by patients or clinicians for diabetes management. Provides plasma-equivalent results. Memory stores 100 test results with date/time. Powered by two AAA batteries.

## Clinical Evidence

Method comparison study performed with 202 diabetic subjects comparing capillary blood results against YSI 2300 Analyzer. Results: slope 0.967, y-intercept 11.98 mg/dL, correlation coefficient (r) 0.972, range 33-514 mg/dL. Analytical precision testing (n=200 per level) showed CVs ranging from 3.1% to 4.3% for within-run and 2.6% to 5.6% for day-to-day precision.

## Technological Characteristics

Amperometric glucose monitoring system. Uses disposable dry reagent strips with glucose oxidase (Aspergillus niger) and potassium ferricyanide mediator on carbon electrodes. Test range 40-600 mg/dL. Sample volume ≥2.0uL. Test time 25 seconds. Powered by 2x 1.5V AAA batteries. Memory capacity 100 tests. Coding via Code Card.

## Regulatory Identification

L. Test Principle:

The Easy Pain Supreme Self Monitoring Blood Glucose System employs a disposable dry reagent strip technology, based on the glucose oxidase method for glucose determination. Each test strip features an electrode containing the enzyme glucose oxidase (Aspergillus niger). A blood sample is applied to the blood collection area at the tip of the strip and is automatically drawn into the reaction zone, where the glucose oxidase catalyzes the oxidation of glucose to produce gluconic acid. During the reaction, a mediator transfers electrons to the electrode surface and generates a current. The amount of the current is proportional to the amount of glucose present in the blood sample. The glucose concentration is displayed on the meter screen after 25 seconds.

M. Performance Characteristics (if/when applicable):

1. Analytical performance:
a. Precision/Reproducibility:
Within-run – Testing was conducted by taking 4 mL of blood that was treated with heparin through a vacuum tube. Glucose was added to the 4 mL of blood

{3}

to generate 5 different levels of glucose concentration for the test. Each of the samples was measured 5 times. The glucose concentration ranges were: 40-50 mg/dL, 51-110 mg/dL, 111-150 mg/dL, 151-250 mg/dL, and 251-400 mg/dL.

|  Range (mg/dL) | n | mean (mg/dL) | SD (mg/dL) | CV (%)  |
| --- | --- | --- | --- | --- |
|  40-50 | 200 | 43 | 2.4 | 4.3  |
|  51-110 | 200 | 95 | 5.3 | 3.5  |
|  111-150 | 200 | 144 | 8.0 | 3.3  |
|  151-250 | 200 | 246 | 13.7 | 3.1  |
|  251-400 | 200 | 398 | 22.1 | 3.3  |

Day to day - Three control solutions of Low, Normal and High were prepared. Each of the controls was measured twice a day, once in the morning and once in the afternoon for a month.

|  Control | n | mean (mg/dL) | SD (mg/dL) | CV (%)  |
| --- | --- | --- | --- | --- |
|  Low | 400 | 56 | 3.10 | 5.6  |
|  Normal | 400 | 129 | 4.49 | 3.5  |
|  High | 400 | 388 | 10.21 | 2.6  |

b. Linearity/assay reportable range:

A blood sample of 25 mL was taken, treated with heparin vacuum tube, to be set for a day. Testing was performed using whole blood supplemented with B-D-glucose to provide samples at seven different blood glucose levels (40-50 mg/dL, 51-80 mg/dL, 81-120 mg/dL, 121-200 mg/dL, 201-300 mg/dL, 301-400 mg/dL, and 400-600 mg/dL). A total of 210 tests were performed using 5 meters among the seven glucose ranges per each strip lot. The linear regression was as follows:

$$
y = 0.9589x + 6.1617, r^2 = 0.9958, Syx = 10.14, n = 630
$$

c. Traceability, Stability, Expected values (controls, calibrators, or methods): N/A

d. Detection limit:

Data was provided to support a reportable range of 40-600 mg/dL.

e. Analytical specificity:

Interference testing was conducted to determine the effect of select endogenous and exogenous substances. A series of test samples, systematically varying in the concentration of the interferents, was prepared by making quantitative, volumetric mixtures of two pools: one at the highest concentration to be tested and the other at the lowest. The substances and concentrations of the interferents are recommended in CLSI EP7-P. Interference from dopamine and L-dopa was observed when the recommended concentration of these drugs was reached in the blood.

{4}

Interference was also observed in higher than therapeutic dosages of acetaminophen, gentisic acid, and methyldopa.

f. Assay cut-off: N/A

2. Comparison studies:

a. Method comparison with predicate device:

Two hundred two people with diabetes performed a finger stick using the Easy Pain Supreme system. A healthcare professional then performed the test on the Easy pain Supreme and the YSI. The range of glucose values for these samples was 33-514 mg/dL. The linear regressions were as follows:

Patient vs YSI  y = 0.967x + 11.98, r = 0.972

Healthcare professional vs YSI  y = 1.007x + 5.04, r = 0.957

b. Matrix comparison: N/A

3. Clinical studies:

a. Clinical Sensitivity: N/A

b. Clinical specificity: N/A

c. Other clinical supportive data (when a. and b. are not applicable): see section 2.a.

4. Clinical cut-off: N/A

5. Expected values/Reference range:

Expected blood glucose levels for people without diabetes (refereced from Joslin Diabetes Manual):

|  Time | Range (mg/dL) | Range (mmol/L)  |
| --- | --- | --- |
|  before breakfast | 70-105 | 3.9-5.8  |
|  before lunch or dinner | 70-110 | 3.9-6.1  |
|  one hour after meals | less than 160 | less than 8.9  |
|  two hours after meals | less than 120 | less than 6.7  |
|  between 2 and 4 AM | greater than 70 | greater than 3.9  |

N. Proposed Labeling:

The labeling is sufficient and it satisfies the requirements of 21 CFR Part 809.10.

O. Conclusion:
The submitted information in this premarket notification is complete and supports a substantial equivalence decision.
