Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients older than 18 years old.
  • Chest imaging shows the presence of peripheral pulmonary lesions (surrounded by pulmonary parenchyma and located below the segmental bronchus as seen radiographically.) suspicious of malignancy, 0.8-5cm in greatest diameter in need of bronchoscopic biopsy for clinical purposes, and the investigators consider it possible to be biopsied with BF-UC290F (the bronchus adjacent or leading to the PPLs are close to 5mm in diameter, thus BF-UC290F is able to arrival/access).
  • Patients without contraindications of bronchoscopy.
  • Patients have good medical adherence and signed informed consent.

Who cannot join

  • Peripheral pulmonary lesion is pure ground-glass opacity.
  • Visible lumen lesions during bronchoscopy
  • The lesions were adjacent to the central airway (trachea, left and right main bronchus, and right middle bronchus), and the biopsies by the Thin Convex Probe EBUS Scope BF-UC290F were conducted without leaf bronchus entry
  • The investigators believe that patient has other conditions that are not suitable for the study.

About this study

Official title: Feasibility and Safety of Thin Convex Probe EBUS Scope BF-UC290F for the Diagnosis of Peripheral Pulmonary Lesions

The purpose of the study is to evaluate the diagnostic value and safety of Thin Convex Probe Endobronchial Ultrasound (TCP-EBUS) Scope for peripheral pulmonary lesions (PPLs)

Read the detailed description

This study will determine the feasibility of the novel thin convex probe endobronchial ultrasound (TCP-EBUS) Scope for the diagnosis of peripheral pulmonary lesions. The primary end point is to clarify the feasibility of using the thin convex probe EBUS scope to biopsy peripheral pulmonary lesions. The secondary objective is to evaluate operation time, sample adequacy, factors affecting the diagnosis rate, etc. The safety, insertion ability, and operability of the thin convex probe EBUS would also be evaluated.

Being tested
Linear Ultrasound Bronchoscope BF-UC290F (Olympus)
Keywords
EBUS-TBNA, diagnostic yield, peripheral pulmonary lesions (PPLs)

What participants receive

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

  • Linear Ultrasound Bronchoscope BF-UC290F (Olympus)Device

    A thin Olympus EBUS bronchoscope BF-UC290F will be used for all endobronchial ultrasound examinations, and biopsies will be conducted with EBUS needles - the ViziShot 2 22G (Olympus).

Study groups in NCT05512533
Study groupRoleWhat they receive
BF-UC290F for diagnosing PPLsExperimentalThin EBUS endoscope is inserted and used to visualize peripheral pulmonary lesions, and biopsies will be conducted by EBUS-TBNA.
Receives: Device: Linear Ultrasound Bronchoscope BF-UC290F (Olympus)

What is being measured

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

  1. Diagnostic yield of BF-UC290F for PPLs

    Diagnostic yield is defined as the proportion of peripheral pulmonary lesions (PPLs) diagnosed via endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in all lesions undergoing bronchoscopy biopsy via EBUS-TBNA.

    Measured: Up to 6 months

Secondary outcomes (5)
  1. EBUS scope operation time

    It is defined as the total time from insertion of the EBUS scope to withdrawal of the EBUS scope

    Measured: Immediately after each operation

  2. The total time of lesion access

    It is defined as the total time from the insertion of the EBUS scope to the arrival confirmed by ultrasound image.

    Measured: Immediately after Each Operation

  3. Factors affecting the diagnosis rate

    Factors affecting the diagnosis rate, including the nature of the lesions, the size of the lesions, the location of the lesions and so on will be analyzed.

    Measured: Up to 6 months

  4. The bronchus level of lesions, and the bronchus level reached with the EBUS scope

    Level: Main bronchus is level 0, lobar bronchus is level 1, segment bronchus is level 2, sub-segment bronchus is level 3, and so on, such as: LB3a is level 3

    Measured: During the procedure

  5. Specimen adequacy

    The adequacy of specimens obtained by Thin Convex Probe EBUS Scope BF-UC290F for pathological typing, molecular testing, and immune checkpoint detection

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Linear Ultrasound Bronchoscope BF-UC290F (Olympus) in people with Peripheral Pulmonary Lesions, run by Shanghai Chest Hospital at 1 site in China.

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 4 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 5 Jun 2025. 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 of BF-UC290F for PPLs (time frame: Up to 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 NCT05512533, which also lists 2 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 5 Jun 2025.
