  • Other known pathology or predisposition that may interfere with the ability to perform the measurement procedures or that may influence calprotectin levels such as acute diarrhea or chronic use of non-steroidal anti-inflammatory drugs

About this study

The objective of the IBDoc® user performance evaluation is to demonstrate the ease-of-use of the IBDoc® calprotectin home test to allow patients with inflammatory bowel disease (IBD) to independently and correctly determine calprotectin concentration in their own stool sample. The study is based on Chapter 8 of the International Organization for Standardization (ISO) Standard, ISO 15197:2013 "In vitro diagnostic test systems - Requirements for blood-glucose monitoring systems for self-testing in managing diabetes mellitus". The study is a prospective, multicenter study, not blinded for patients, and includes a total of 61 patients.

Read the detailed description

The patient will determine the calprotectin concentration in their own stool sample using the IBDoc® assay. For this, the patient will collect a stool sample in a standard collection tube at home. The patients will return to the clinical site with the specimen, where they will receive a standardized IBDoc® training. They will also be given opportunity to perform an IBDoc® practice test using the collected sample. The patients will then perform the full IBDoc® assay using the collected stool sample under the observation of the healthcare provider, who will assess their performance. The final result - the interpretation of the IBDoc® lateral flow assay by the CalApp® smartphone application, to yield a final μg/g calprotectin concentration in stool, will be sent to the health care provider (HCP) via the IBDoc® Web Portal.

The usability of the IBDoc® test will be evaluated according to the following factors:

  • Trueness/ accuracy - the patients' ability to obtain correct results will be evaluated by comparing patients' IBDoc® results with reference measurements from the same stool sample using the BÜHLMANN fCAL® ELISA, performed at a laboratory site. For reference measurements the HCP at the clinical site will obtain 3 CALEX® Cap extracts from the patient's stool sample, which will be stored frozen and shipped to the laboratory site.

To exclude bias or inaccuracy that may arise from the analytical performance characteristics of the IBDoc® assay itself, a comparative IBDoc® assay will be performed according to the instructions for use, with the patients' samples in a laboratory. For the comparative IBDoc® measurement the HCP at the clinical site will obtain one CALEX® Valve extract from the patient's stool sample, which will be stored frozen and shipped to the laboratory site.

-IBDoc® Calprotectin test usability, clearness of obtained result, and comprehensiveness of the Instruction for Use will be assessed in the following ways:

  • Patient's questionnaire
  • HCP's questionnaire - human factors evaluation

The ability of patients to correctly collect and extract stool samples using the CALEX® Valve device will be analysed as an additional module within the IBDoc® User Performance Evaluation. The CALEX® Valve extracts obtained by the patients as part of the IBDoc® procedure will be stored frozen and shipped to the laboratory site. Calprotectin levels in the patients' CALEX® Valve extracts will be determined with the BÜHLMANN fCAL® ELISA and compared to calprotectin reference values obtained from the same stool samples by the HCP's.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IBDoc calprotectin testDiagnostic test

    Patients are asked to perform a single IBDoc calprotectin home test.

  • questionnaireOther

    Patients evaluate the ease-of-use of the test, clearness of test results and comprehensiveness of the instructions for use through a specific questionnaire implementing Likert scales.

What is being measured

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

  1. Trueness/ accuracy of patients IBDoc® results

    Patients' IBDoc results are compared to reference calprotectin values obtained by laboratory methods

    Measured: 24 hours

  2. Quantifiable feedback from the enrolled patients about the ease-of-use of the test

    Ease-of-use of the test, clearness of test results and comprehensiveness of the instructions for use is assessed in a questionnaire, with 12 statements, scored on a 1-to-5 Likert scale, with one (1) indicating "I strongly disagree" and five (5) "I strongly agree". The mean and standard deviation of scores obtained from all participating patients will be evaluated for each statement.

    Measured: 24 hours

  3. Quantifiable feedback from healthcare providers

    Quantifiable feedback from the healthcare providers about the ability of the patients to correctly perform the IBDoc® assay. Assessment will be made through a questionnaire with five (5) statements, scored on a 1-to-5 Likert scale, with one (1) indicating "I strongly disagree" and five (5) "I strongly agree". The mean and standard deviation of scores obtained from all participating healthcare providers will be evaluated for each statement.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing IBDoc calprotectin test and questionnaire in people with Inflammatory Bowel Diseases, run by Bühlmann Laboratories AG at 3 sites in Canada.

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 8 inclusion and 3 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 24 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Canada. 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?

Trueness/ accuracy of patients IBDoc® results (time frame: 24 hours). The study lists 3 primary outcomes in all. 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 NCT03408249, 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 24 Jan 2018.
