About this study

The study consists of 2 parts:

The objective of part 1 of this study is the performance of a short evaluation of system accuracy for 25 subjects in order to familiarize the study personnel with the study BGMS to be used during the planned evaluation of system accuracy (see IDT-1416-BL (Part 2)), ensure that the Karajishi meters are fully functioning, assure and document the accuracy of the comparison method, evaluate and validate the processes and procedures of the study methodology. The objective of part 2 of this study is the evaluation of system accuracy following ISO 15197:2013 (E), 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.

This study will be performed for Karajishi Contour and Karajishi Contour TS (manufacturer: Bayer Healthcare Diabetes Care) with 3 reagent system lots for each BGMS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of System Accuracy according to ISO 15197 (see description)

    System accuracy criteria:

    1. Following 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.
    1. Applying ISO 15197:2003 accuracy criteria:
    • 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 < 75 mg/dl (4.2 mmol/l) or within ± 20 % at glucose concentrations ≥ 75 mg/dl (4.2 mmol/l).

    Measured: For each subject, the experimental phase has an expected duration of up to 6 hours

Questions about this trial

What is this clinical trial studying?

A study testing Blood glucose monitoring systems for self-testing in people with Diabetes, run by Institut für Diabetes-Technologie Forschungs- und Entwicklungsgesellschaft mbH an der Universität Ulm at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of System Accuracy according to ISO 15197 (see description) (time frame: For each subject, the experimental phase has an expected duration of up to 6 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02358408, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jan 2016; AzTrials last refreshed its copy on 8 Nov 2026.
