About this study

Official title: Electromagnetic Navigation Bronchoscopy for the Diagnosis of Peripheral Pulmonary Nodules: a Real World Study

The study is designed as a multi-center prospective trial of ENB for the diagnosis of peripheral pulmonary nodules in the real world. The purpose of the study is to identify the optimal method of using ENB.

Read the detailed description

The study will be conducted at no less than 5 clinical centers. Patients with peripheral pulmonary nodules suspicious for malignancy will be enrolled in the study. ENB will be performed with/without other guided bronchoscopy techniques and/or ROSE. Different biopsy methods will be recorded as well. The primary endpoint is the diagnostic yield of ENB. The secondary endpoints include factors affecting diagnostic yield, operation time, complications, safety and so on.

Being tested
Electromagnetic navigation bronchoscopy (ENB)
Keywords
electromagnetic navigation bronchoscopy(ENB), peripheral pulmonary nodules, diagnostic yield

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Electromagnetic navigation bronchoscopy (ENB)Procedure or surgery

    ENB is carried out by a ENB system(LungCare, China) with/without other guided bronchoscopy techniques and/or ROSE, which can offer real-time navigation for bronchoscopy reaching peripheral pulmonary nodules.

What is being measured

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

  1. Diagnostic yield

    Diagnostic yield is defined as proportion of true positive and true negative. The primary endpoint is diagnostic yield of ENB with/without other guided bronchoscopy techniques or ROSE.

    Measured: One year

Secondary outcomes (5)
  1. The difference of diagnostic yield among groups of different methods of using ENB

    ENB will be performed with/without other guided bronchoscopy techniques and/or ROSE. Different biopsy methods will be recorded as well.The difference of diagnostic yield among groups of different methods of using ENB will be analyzed.

    Measured: One year

  2. Factors affecting diagnostic yield

    Factors affecting diagnostic yield including lesion size,bronchus sign, location and so on will be analyzed.

    Measured: One year

  3. The difference of diagnostic yield among groups using different locatable guides

    There are three kinds of locatable guides with different outer diameters. The difference of diagnostic yield among groups using different locatable guides will be analyzed.

    Measured: One year

  4. Operation time

    Operation time includes total operation time,total GS time and total EBUS time.

    Measured: One year

  5. Incidence of complications

    Complications mean a composite of operation-related serious adverse events (pneumothorax, bleeding, etc.) during and after the operation.

    Measured: One year

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 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: finished, as of the sponsor's last update on 3 Aug 2022. 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 China. 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 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 (time frame: One year). 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 NCT03716284, which also lists 6 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 3 Aug 2022.
