Study summary

The primary aim is to develop a software algorithm that has the capacity to detect the normal 18 anatomical structures of the lung by using the position of the scope during the bronchoscopy procedure and using existing bronchoscopy technology.

Read the detailed description

2.000 subjects, preferable 150-200 number of patients per site. The 2.000 videos will be divided into an 80%/20% split (training and testing). It is a wish to obtain a spread of videos coming from across Europe, preferable from Germany, France and Denmark, with up to 800 videos coming from Denmark

The patient population indicated are patients indicated for full airway bronchoscopy. Of this group it is the aim to enrol the following:

  1. Patients with obstructing tumors (when tumor blocks the view of the camera) - no more than 5% (120 patients) of studies
  2. Bronchoscopies on indication of haemoptysis (active bleeding) - no more than 5% (120 patients) of studies
  3. Patients with stents or valves - no more than 5% (120 patients) of studies bronchoscopies.
  4. Patients with former lung operations, partial or full resections - no more than 2% (48 patients).

Study population

The bronchoscope is used to confirm or exclude a diagnosis in adult patients with airway complaints to identify a potential disease.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Oral and written participant information has been given (NA for Denmark)
  2. The subject has signed (NA for Denmark)
  3. Patients indicated for full airway bronchoscopy (identifying all 18 anatomical segments)
  4. Patients older than 18

Exclusion criteria

Exclusion Criteria:

  1. Subject with serious lung disease which investigator considers not appropriate for this examination.
  2. Lack of patient cooperation for bronchoscopy (patient with mental disorders, dysgnosia, psychological disorder...)
  3. Subjects unable to give consent (NA for Denmark)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Number of anatomical segments accessed during bronchoscopy

    accurate photo documentation of all 18 anatomical segments +/- abnormalities

    Time frame: 1 day

Secondary outcomes

  1. Number of anatomical segments identified

    Identified anatomical segments by the core lab/ Identified anatomical segments by the Machine Learning (after training, using the test videos).

    Time frame: 1 day

  2. Rate of total number of lesions detected

    total lesions detected by the core lab/ total lesions detected by Machine Learning (after training, using the test videos).

    Time frame: 1 day

  3. Number of sections and lesions detected by core lab and machine learning

    Anatomical sections + lesions detected by core lab versus anatomical sections + lesions detected by machine learning

    Time frame: 1 day

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2020 to primary completion in Dec 2021, 12 months.

Of 148 industry-sponsored observational studies under Neoplasms, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 102. This study's 12 months is below that.

Counting every sponsor, half of 1,246 studies reached it within 58 months; a quarter within 24 and three quarters within 210.

Neoplasms covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 3, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
