Study summary

The primary aim of this study is to investigate the performance of Breath Biopsy RD for the detection of SARS-CoV-2 in both a clinical and at home setting.

Read the detailed description

This study aims to evaluate Owlstone Medical's Breath Biopsy RD Collectors for the detection of SARS-CoV-2 infection. These single use disposable breath capture devices can be used independently by individuals and shipped to be analysed in a central lab for the presence of SARS-CoV-2 using established existing PCR assays available in any reference lab. The aerosol collectors furthermore directly sample exhaled breath aerosols. As such they directly sample the primary transmission route for the virus. This could result in a higher rate of retrieval of viral RNA in infected individuals thereby increasing the sensitivity of the applied PCR assay. This is underpinned by the fact that CT abnormalities in the lower airways appear to occur prior to upper respiratory tract samples becoming positive in cases suffering from nCOVID19, suggesting lower airway viral loads could be higher. Combined, this could enable more widespread access to diagnostics, reduce the need for repeat testing, decrease the need for healthcare professionals to perform diagnostic tests and reduce cross-contamination risk.

Interventions

  • DeviceBreath Biopsy face masks with removable filters and fitted PVA strip

    Device developed for collection of breath samples

  • Diagnostic testNasopharyngeal swab

What researchers measure

Primary outcomes

  1. Positive control for technical validation

    The purpose of this stage is to confirm the optimal extraction protocol to detect the presence of SARS-CoV-2 from the aerosols captured in the Breath Biopsy RD device. Up to two Breath Biopsy RD sample will be collected alongside a nasopharyngeal. The swab obtained during this stage is to be analysed in parallel to the extracted breath aerosols in the lab of the lab and will be used as a positive control.

    Time frame: 1 year

Secondary outcomes

  1. Evaluation of test performance

    The aim is to assess the test performance of the Breath Biopsy RD devices in a real live clinical setting. Subjects with a high clinical suspicion of nCOVID-19 based on clinical triage will be requested to participate. A single Breath Biopsy RD collector will be collected in parallel with the standard diagnostic work-up consisting of a CT-scan and a nasopharyngeal swab.

    Time frame: 1 year

Other outcomes

  1. Evaluation of at home test

    The aim of the final outcome is to evaluate the performance and acceptability of using the Breath Biopsy RD as an at home test for identification of the presence of SARS-CoV-2. The OLVG phone application used for triage of the presence of nCOVID-19 will be used to identify subjects at the highest risk of having nCOVID-19. These subjects will be sent a Breath Biopsy RD collector and oropharyngeal swab for at home testing. Any subject who has a positive Breath Biopsy test for SARS-CoV-2 will be contacted and advised to receive a nasopharyngeal test for assessment of viral presence. Both tests will be self-administered to mimic an at home use scenario. The performance of both tests will be confirmed from the perspective of 1. Adherence 2. Subject comfort 3. Number of SARS-CoV-2 positive cases.

    Time frame: 1 year
