Trial summary

In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy.

About this study

Official title: High-definition Videobronchoscopy With Optical Enhancement for the Diagnosis of Endobronchial Sarcoidosis: a Pilot Study

In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy. Furthermore, in combination with improved video processor units, some HD videobronchoscopes offer post-processing real-time image enhancement (i-scan technology). Preliminary studies, performed in the setting of lung cancer, suggest that HD bronchoscopy with optical image enhancement (OE) may result in better detection of subtle vascular abnormalities in the airways, which are often associated with preneoplastic lesions. We hypothesize that HD videobronchoscopy could help identify bronchial involvement from sarcoidosis before it is (plainly) visible by conventional bronchoscopy.

Read the detailed description

Sarcoidosis is a systemic disorder of unknown cause that primarily involves the lung and lymphatic systems and that can be more reliably diagnosed if a compatible clinical picture is combined with a pathologic demonstration of non-necrotizing epithelioid-cell granulomas. As the thorax (bronchi, lung parenchyma, and/or intrathoracic lymph nodes) is almost invariably involved, bronchoscopy with its ancillary sampling procedures (endobronchial biopsy, transbronchial lung biopsy, bronchoalveolar lavage, conventional and ultrasound guided-transbronchial needle aspiration, endoscopic ultrasound with fine needle aspiration) has been the diagnostic tool most frequently used to confirm pathologically the clinical suspect of sarcoidosis.

Among the possible bronchoscopic sampling procedures, endobronchial biopsy (EBB), which is the easiest and safest, has long been used, even though its value has been assessed in small studies, mostly retrospective. Although its diagnostic yield has been shown to be widely variable (5%-71%) across different studies, EBB has constantly demonstrated to increase the diagnostic success of bronchoscopy in sarcoidosis when coupled with other sampling methods. In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy. Furthermore, in combination with improved video processor units, some HD videobronchoscopes offer post-processing real-time image enhancement (i-scan technology). Preliminary studies, performed in the setting of lung cancer, suggest that HD bronchoscopy with optical image enhancement (OE) may result in better detection of subtle vascular abnormalities in the airways, which are often associated with preneoplastic lesions. We hypothesize that HD videobronchoscopy could help identify bronchial involvement from sarcoidosis before it is (plainly) visible by conventional bronchoscopy.

What is being measured

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

  1. Diagnostic yield of endobronchial biopsy guided by HD videobronchoscopy for the detection of granulomas

    The diagnostic yield will be calculated on a per patient basis (number of patients in whom the pathological examination of endobronchial biopsies shows non necrotizing granulomas/all the patients submitted to endobronchial biopsies)

    Measured: 1 month

Secondary outcomes (5)
  1. Prevalence of airway abnormalities in patients with suspected sarcoidosis at HD bronchoscopy

    The prevalence of airway abnormalities will be calculated on a per patient basis (number of patients in whom the HD videobronchoscopy shows abnormalities in the endoscopically visible airways/all the patients submitted to HD videobronchoscopy)

    Measured: 1 day

  2. Prevalence of different patterns of airway abnormalities in patients with suspected sarcoidosis at HD videobronchoscopy

    The following patterns of airway abnormalities, well described in the literature in the setting of endobronchial sarcoidosis, will be evaluated for the assessment of the present endpoint: a) cobblestoning (diffuse, coalescing nodules); b) nodularity (sparse, discrete nodules); c) thickening; d) plaque (infiltrative, raised, flat, white or yellowish areas); e) marked hyperaemia. In those cases in which airway abnormalities are detected, but they do not fall into any of the above patterns, they will be classified into a 6th pattern named "miscellanea".

    Measured: 1 day

  3. Specificity for the detection of granulomas of the above 6 different patterns of airway abnormalities identified during HD bronchoscopy

    This endpoint will be calculated on a per-lesions basis (number of cases of airway abnormality referring to one the 6 predefined patterns in which the pathological examination of endobronchial biopsies shows non necrotizing granulomas/all the airway abnormalities referring to that specific predefined pattern submitted to endobronchial biopsy).

    Measured: 1 month

  4. The interobserver agreement for the identification of the above 6 predefined patterns of airway abnormalities.

    At the end of the study, the videos referring to each endobronchial abnormality submitted to biopsy in each enrolling center will be independently classified by two interventional pulmonologist blinded to the clinical, radiological and pathological findings.

    Measured: 1 month

  5. Diagnostic yield for the detection of endobronchial granulomas according to clinical, radiological and endoscopic findings.

    The association between the following findings and the diagnostic yield of EBBs will be assessed: sex; ethnicity; sarcoidosis stage (I-IV); presence versus absence of endobronchial abnormalities at HD bronchoscopy; pattern of airway abnormality at HD bronchoscopy.

    Measured: 6 months

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?

Diagnostic yield of endobronchial biopsy guided by HD videobronchoscopy for the detection of granulomas (time frame: 1 month). 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 NCT04743596, which also lists 1 linked publication.

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 10 Jan 2023.
