About this study

Systemic sclerosis (SSc) is a generalized disorder of connective tissue, arterioles and microvessels, characterized by the occurrence of fibrosis and vascular obliteration phenomena. The alterations in lung microvessels are found in pulmonary involvement of scleroderma, which are the most serious complications of the disease.

In pulmonary emphysema, there are also changes in pulmonary microvasculature, which are involved in the onset and development of the disease.

The confocal endomicroscopy is an endoscopic technique which can be performed during a bronchoscopy. This technique makes it possible to observe in real time the most distal pulmonary elements at the microscopic scale. After injection of fluorescein, then the technique of observing the pulmonary microvasculature, in vivo and in situ.

The characterization of microvascular lesions in these two pathologies could improve understanding of their mechanisms and ultimately improve the early management of patients.

What is being measured

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

  1. Measurement of extra-alveolar diameter of capillaries of patient with pulmonary emphysema or pulmonary scleroderma

    Extra-alveolar diameter of capillaries is assessed using in vivo confocal endomicroscopy

    Measured: Day 1

  2. Measurement of intercapillary distance of patient with pulmonary emphysema or pulmonary scleroderma

    Intercapillary distance is assessed using in vivo confocal endomicroscopy

    Measured: Day 1

  3. Measurement of length of the capillary portions of patient with pulmonary emphysema or pulmonary scleroderma

    Length of the capillary is assessed using in vivo confocal endomicroscopy

    Measured: Day 1

Secondary outcomes (2)
  1. Measurement of alveolar diameter entries of patient with pulmonary emphysema or pulmonary scleroderma

    Alveolar diameter entries is assessed using in vivo confocal endomicroscopy

    Measured: Day 1

  2. Measurement of axial thickness of elastic fibers of patient with pulmonary emphysema or pulmonary scleroderma

    Axial thickness of elastic fibers is assessed using in vivo confocal endomicroscopy

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Bronchoscopy with in vivo confocal endomicroscopy in people with Pulmonary Disease and Pulmonary Emphysema, run by University Hospital, Rouen at 1 site in France.

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 13 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: stopped early, as of the sponsor's last update on 14 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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 was stopped early (reason given: Difficulty in enrolling new patients). Results are not available in the source record.

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?

Measurement of extra-alveolar diameter of capillaries of patient with pulmonary emphysema or pulmonary scleroderma (time frame: Day 1). The study lists 3 primary outcomes in all. 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 Apr 2026.
