About this study

The purpose of this feasibility study is to test a device which analyzes breath and may allow doctors and health professionals to immediately determine if an ill patient has a specific type of bacterial infection. This will allow a health professional to provide immediate targeted antibiotics to properly start treatment without delay.

Read the detailed description

Community acquired, or hospital acquired [nosocomial] infections [pathogens] are a common cause for morbidity and mortality. Initiation of antibiotic treatment is by best guess or using a broad spectrum antibiotic. The improper administration of antibiotics is known to lead to the developing specter of antibiotic resistant organisms.

Certain community acquired bacterial infection such as Streptococcus upper respiratory tract infections carry increased risk of morbidity secondary to risk of developing abscess, glomerulonephritis, and/or rheumatic fever. Commonly, most upper respiratory tract infections are caused by viruses. However due to the unknown pathogen causing an upper respiratory tract infection, with the risks of potential chronic severe complications from Streptococcus, initial treatment starts with either an antibiotic, or a typical 3day wait for bacterial culture result. Quite often, the wait-and-see approach in the community is not undertaken because of the difficulty in returning for a follow-up appointment.

The risk of a developing antibiotic resistant bacteria is well-known and is one of the greatest health threats worldwide leading to longer hospitalizations, higher medical costs and death, according to the World Health Organization. Thus a point of care device which would enable physicians or other medical practitioners to promptly discriminate between Streptococcal or other antibiotic sensitive pathogens versus non antibiotic sensitive viral causes of specific upper respiratory tract infectious pathogens is needed.

  1. First posted5 Dec 2016 (estimated)
  2. Study startNov 2016
  3. Primary completionNov 2017 (estimated)
  4. Study completionNov 2018 (estimated)

Why it stopped: 2 NaNose devices provided inconsistent results in lab calibration testing

Questions about this trial

What is this clinical trial studying?

An observational study of Infection, Community-Acquired and Communicable Disease, run by BreathTec Biomedical Inc..

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 6 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: withdrawn, as of the sponsor's last update on 9 Nov 2017. 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 was withdrawn before enrolling participants, so there are no results.

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?

Evidence of Infection detected by exhaled breath analysis confirmed by laboratory culture (time frame: Within 3 to 7 days of obtaining culture and exhaled breath sample). 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 NCT02981550, 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 9 Nov 2017.
