About this study

This is a confirmatory study that seeks to examine whether respiratory-responsive vocal biomarkers have potential to respond to COVID-19 infection status and respiratory symptom severity. Patients with suspected COVID-19 and healthy controls will submit daily voice samples and symptom inventories on their personal smartphone devices for 14 days.

Read the detailed description

This is an observational study examining the potential to use voice analysis to aid in the identification of COVID-19 and as an aid to monitoring of respiratory symptoms of COVID-19. Patients with suspected COVID-19 and healthy controls will be enrolled and use their own smartphone device to provide daily voice samples and symptom inventories. This study seeks to confirm and extend findings from preliminary data from patients with asthma, COPD and cough that has indicated the potential of respiratory responsive vocal biomarkers (RRVB) to respond to respiratory diagnoses and symptom severity. The same RRVB will be examined to confirm whether this potential generalizes to respiratory symptoms associated with COVID-19

What participants receive

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

  • Smartphone-based voice and self-reported symptom collectionOther

    Voice samples and COVID-19 symptom inventories will be collected on participant smartphone devices. No outcomes or feedback is provided on acquired data during trial conduct but will be used for confirmatory data analysis post study

Study groups in NCT04582331
Study groupRoleWhat they receive
COVID-19 positivePatients with suspected COVID-19 based on presence of at least one newly emerged relevant symptom that has emerged at most 10 days prior to enrollment. COVID-19 positive status is confirmed by diagnostic testing and clinical diagnosis.
Receives: Other: Smartphone-based voice and self-reported symptom collection
COVID-19 negative, symptomaticPatients with suspected COVID-19 based on presence of at least one newly emerged relevant symptom that has emerged at most 10 days prior to enrollment. COVID-19 negative status is confirmed by diagnostic testing and clinical diagnosis.
Receives: Other: Smartphone-based voice and self-reported symptom collection
Normal Healthy VolunteersAsymptomatic healthy participants recruited from hospital staff or co-living family members, or co-living family member of a COVID-19 positive study participant.
Receives: Other: Smartphone-based voice and self-reported symptom collection

What is being measured

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

  1. Vocal biomarker performance in COVID-19 positive vs. healthy controls

    Sensitivity, Specificity and Diagnostic Odds Ratio of RRVB, either alone or in combination with a symptom inventory, to identify COVID-19 positive patients vs. asymptomatic healthy controls

    Measured: Day 1 of study enrollment

Secondary outcomes (2)
  1. Vocal biomarker vs. symptom burden correlation in COVID-19 positive

    Mean and 90% confidence interval of the correlation coefficient distribution between RRVB-based scores and self-reported respiratory symptom burden pooled across study days within individual COVID-19 patients

    Measured: Pooled across study Days 1-14

  2. Vocal biomarker performance in COVID-19 positive vs. COVID-19 negative symptomatic

    Sensitivity, Specificity and Diagnostic Odds Ratio of RRVB, either alone or in combination with a symptom inventory, to discriminate COVID-19 positive vs. symptomatic COVID-19 negative patients on Day 1

    Measured: Day 1 of enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by Sonde Health at 4 sites in 2 countries.

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 21 inclusion and 7 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 14 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, India. 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?

Vocal biomarker performance in COVID-19 positive vs. healthy controls (time frame: Day 1 of study enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 May 2021.
