Clinical System Accuracy Evaluation With OneTouch® Verio Flex Blood Glucose Monitoring System (BGMS)

Overview

The objective of this study is the evaluation of system accuracy based on EN ISO 15197:2015 (ISO 15197:2013), clause 6.3 in which accuracy requirements and applicable test procedures for blood glucose monitoring systems intended for self-monitoring of blood glucose by patients are stipulated. ISO 15197:20132 was harmonized with the regulations of the European Union as EN ISO 15197:2015. This harmonization had no impact on the requirements and procedu¬res in ISO 15197:2013; changes were made to the foreword and an informative annex. In this study, system accuracy evaluation will be performed for OneTouch® Verio Flex (LifeScan Europe) on behalf of LifeScan Scotland Limited (customer) with three different reagent system lots.

Study Type

  • Study Type: Interventional
  • Study Design
    • Intervention Model: Single Group Assignment
    • Primary Purpose: Other
    • Masking: None (Open Label)
  • Study Primary Completion Date: April 3, 2017

Interventions

  • Device: Blood glucose monitoring systems for self-testing (BGMS)
    • Measurement procedure Subjects will be asked to wash and dry their hands before the measurements. The measurement procedure for each reagent system lot of a BGMS will be as follows: Study personnel will collect a capillary blood sample from the subject’s fingertip by skin puncture. Duplicate measurements on the sample will be consecutively performed with 2 test meters using reagent system units from the same vial / package. Capillary blood for measurements with all 3 test strip lots and for both comparison measurements will be taken from the same finger puncture. The sample will be applied to the reagent system units following specifications in the manufacturer’s labelling.

Arms, Groups and Cohorts

  • Experimental: Blood glucose measurement

Clinical Trial Outcome Measures

Primary Measures

  • System accuracy criteria
    • Time Frame: For each subject, the experimental phase has an expected duration of up to 6 hours
    • Based on EN ISO 15197:2015 (ISO 15197:2013) (E), the BGMS shall meet both of the following criteria: Criterion A: 95 % of the measured glucose values shall fall within either ± 15 mg/dl (0.83 mmol/l) of the average comparison measurement result at glucose concentrations < 100 mg/dl (5.55 mmol/l) or within ± 15 % at glucose concentrations ≥ 100 mg/dl (5.55 mmol/l). Each lot shall pass acceptability criterion A. Criterion B: 99 % of individual glucose measured values shall fall within zones A and B of the Consensus Error Grid (CEG) for type 1 diabetes.
