About this study

Official title: Clinical Evaluation of the BioFire FilmArray® BioThreat-E Test for the Diagnosis of Ebola Virus Disease in West Africa

The aim of our study is to assess the analytical and clinical performance of the FilmArray (FA) BioThreat-E test (BioFire®) for the diagnosis of Ebola virus disease in the field in Guinea versus conventional molecular techniques.

Read the detailed description

The study will be conducted at the "Laboratoire des Fièvres Hémorragiques Virales" in Donka National Hospital (Conakry, Guinea), which is the Reference Laboratory for Hemorrhagic Fevers in Guinea. The reference based population includes the regions of Conakry and Coyah. No specific invasive intervention is required for this research protocol and the study does not interfere with the management of the patients according to the ongoing practices in Donka Ebola Treatment Center and in Coyah Ebola Treatment Center. Each participant will be verbally informed before signing an informed consent. Clinical data will be collected and recorded via a source document questionnaire - Clinical Report Form - based on the routine clinical data already provided to the laboratory according to the practices. Another questionnaire will be submitted to the biologist and technicians involved in the study to assess the practicability of the FilmArray technology, compared to conventional techniques, in terms of time to results, duration of test manipulation, sense of personnel safety for specimen handling, overall workload after each day, and preference of lab professionals.

As the main objective, analytical performance (sensitivity and specificity) and clinical performance (positive and negative predictive values) of the FA BioThreat-E test in whole blood will be evaluated in comparison with the QuantiTect® Probe RT-PCR (Qiagen) and the RealStar® Filovirus Type RT-PCR Kit 1.0 (Altona) both tests performed on serum.

The status for EVD will be defined for each patient based on the result of routine testing:

  • Positive patients: patients enrolled in the study showing positive results with the two routine PCR performed in the lab: QuantiTect Probe RT-PCR® and RealStar® Filovirus Type RT-PCR Kit 1.0.
  • Negative patients: patients enrolled in the study showing negative results with the two routine PCR performed in the lab: QuantiTect Probe RT-PCR® and RealStar® Filovirus Type RT-PCR Kit 1.0.
  • Equivocal patients: all other results showing a discrepancy between the two routine tests.

As a secondary objective, the possibility of using the FilmArray (FA) BioThreat-E test on non-invasive specimens will also be assessed. Urine and saliva specimens will be analyzed by FA for confirmed positive cases only (based on routine testing), for patients able to provide saliva and/or urine specimens according to their health condition.

This research protocol was approved by the Guinean Ethical Committee.

What is being measured

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

  1. Number of positive/negative patients for the detection of Ebola virus RNA with the BioThreat-E test performed on whole blood.

    Number of positive/negative patients for the detection of Ebola virus RNA with the BioThreat-E test in comparision with their Ebola Virus Disease status as defined based on the result of routine testing.

    Measured: Through study completion, an average of 6 months.

Secondary outcomes (2)
  1. Number of urine specimens positive/negative for the detection of Ebola virus RNA with the BioThreat-E test, in patients positive for Ebola Virus Disease based on routine testing, and able to provide a urine specimen.

    Measured: Through study completion, an average of 6 months.

  2. Number of saliva specimens positive/negative for the detection of Ebola virus RNA with the BioThreat-E test, in patients positive for Ebola Virus Disease based on routine testing, and able to provide a saliva specimen.

    Measured: Through study completion, an average of 6 months.

An observational study of Ebola Virus Disease, run by BioMérieux.

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 2 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 18 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Number of positive/negative patients for the detection of Ebola virus RNA with the BioThreat-E test performed on whole blood. (time frame: Through study completion, an average of 6 months.). 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 NCT02658331, which also lists 3 linked publications.

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 18 Jan 2016.
