Confocal Laser Endomicroscopy VERification

United States, Austria, Czechia208 participantsStarted 2023-10-18

Plain-language summary

The goal of this multi-center randomized clinical trial is to evaluate the added value of needle based confocal laser endomicroscopy (nCLE)-imaging to regular diagnostic bronchoscopic peripheral lung lesion analysis on the diagnostic yield in patients with peripheral pulmonary nodules suspect for malignancy. The main question\[s\] it aims to answer are: To determine if the addition of nCLE-imaging to conventional diagnostic bronchoscopic peripheral lung lesion analysis results in an improved diagnostic yield (defined as the proportion of patients in whom the bronchoscopic procedure results in a definitive diagnosis out of the total number of patients that have received the diagnostic bronchoscopic procedure). Participants will undergo diagnostic bronchoscopy either with or without the addition of nCLE imaging before each TBNA. Based on the feedback of the CLE images on (in)correct placement of the needle, the needle might be repositioned before sampling. Comparison between the diagnostic yield of these groups will be done including subgroup analysis.

Inclusion criteria

. ≥18 years of age
. Suspected malignant peripheral lung lesion with an indication for a bronchoscopic diagnostic work-up as determined by the attending physician or tumor board. Peripheral pulmonary lesions are defined as lesions located beyond the visible segmental bronchi, not detectable by regular flexible bronchoscopy
. Bronchus sign on pre-procedural CT or estimated confidence for successful navigation to the nodule resulting in a r-EBUS signal
. Solid part of the lesion must be ≧10 mm
. Largest dimension of lesion size on CT ≦30 mm (long-axis)
. Ability to understand and willingness to sign a written informed consent

Exclusion criteria

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
