About this study
Official title: Cone Beam Computed Tomography - Guided Navigation Bronchoscopy for Peripheral Pulmonary Nodules: A Randomized Trial
The purpose of this study is to determine if the cone beam computed tomography (CBCT)-guided navigation bronchoscopy is better in diagnosing lung nodules compared to navigation bronchoscopy alone.
Read the detailed description
This clinical trial examines the effectiveness of a treatment comparing it to another known treatment.
The U.S. Food and Drug Administration (FDA) has approved the navigation bronchoscopy as a treatment option for this disease.
The U.S. Food and Drug Administration (FDA) has approved the Cone-Beam CT scan as a treatment option for this disease.
This research study involves a screening period, a procedure and follow up visits.
The names of the study interventions involved in this study are:
- Computed tomography (CBCT)-guided navigation bronchoscopy (CBCT-guided NB)
- Navigation bronchoscopy alone
Participants will receive the study procedure and will be followed for up to 6 months.
It is expected that about 136 people will take part in this research study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Diagnostic Yield
The overall diagnostic yield will be calculated by adding the number of true positives (TP) for both malignancy and benign disease in the numerator and dividing by the total number of procedures performed for each arm of the study.
Proportions will be compared with the Chi-Square Test as this test is equivalent to the z-test of two proportions (26). A p-value <0.05 will be considered as statistically significant.
Measured: 6 months
Secondary outcomes (3)
Overall Incidence of Procedure-related Complications
To compare complications between navigational bronchoscopy alone and CBCT guided bronchoscopy.
Measured: 6 months
Additional Diagnostic Procedures in Navigational Bronchoscopy Alone and CBCT Guided Bronchoscopy.
To compare the need of additional diagnostic procedures in navigational bronchoscopy alone and CBCT guided bronchoscopy.
Measured: 6 Months
Navigational Time in Bronchoscopy Alone and CBCT Guided Bronchoscopy.
To compare the navigational time defined as the time between the start of catheter driving after registration until catheter is parked for biopsy.
Measured: 6 Months

Questions about this trial
What is this clinical trial studying?
A study testing Navigation Bronchoscopy and Cone beam computed tomography (CBCT) in people with Peripheral Pulmonary Nodules and Lung; Node, run by Beth Israel Deaconess Medical Center at 1 site in United States.
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 4 inclusion and 11 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 22 Sep 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 United States. 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?
Yes. Results are posted in the registry (first posted 19 Nov 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Overall Diagnostic Yield (time frame: 6 months). 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 NCT04758403, which also lists 25 linked publications.
Does a listing mean the treatment is approved or proven to work?
