What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study uses a special bronchoscopy technique called narrow band imaging to look at blood vessel patterns in the airways of people with COVID-19. Researchers will compare images from three groups: patients with COVID-19, patients with other lung infections, and patients with lung nodules. The goal is to see if COVID-19 causes unique changes in the tiny blood vessels of the bronchial tree.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If distinct vessel patterns are found, this could help doctors better understand how COVID-19 affects the lungs and possibly guide future diagnosis or treatment.
What could go wrong
This is a small, observational study with only 30 participants. It describes patterns but does not test any treatment, so it may not lead to direct clinical changes.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

\- Patients who undergo bronchoscopy with image and/or videos recording of NBI aspect of the proximal bronchial tree (carina, right and left upper lobe). Three groups of patients will be selected: 1) Patients hospitalized with SARS-CoV2 infection proven by RT-PCR test ; 2) patients hospitalized with lower respiratory tract infections unrelated to SARS-CoV2 (RT-PCR negative for SARS-CoV2) ; 3) Patients who have had bronchoscopy performed as part of the assessment of a distal pulmonary nodule (RT-PCR negative for SARS-CoV2).
