January 23, 2026 updated by: Marc Fortin, Institut universitaire de cardiologie et de pneumologie de Québec, University Laval

OPTimizing Endobronchial Ultrasound Sampling In Suspected Non Small Cell Lung Cancer for Molecular Markers : A Pragmatic Randomized Controlled TriaL

In this monocentric randomized controlled trial, 120 potential non small cell lung cancer (NSCLC) patients for which tissue diagnosis and material for next generation sequencing (NGS) is required for clinical management will be approached the day of their endobronchial ultrasound to participate in the study. They will be randomized to 2 vs 3 passes/lymph node and will all undergo liquid biopsy. The co-primary outcomes are 1)the rate of obtention of adequate material for NGS testing with 2 vs 3 passes/lymph node and 2)the percentage of patients for which liquid biopsy allows to identify clinically pertinent findings not available from tissue biopsy

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
120

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Suspected or confirmed NSCLC requiring tissue sample for NGS testing to guide clinical management
  • Presence of at least 2 targets accessible by EBUS or EUS suspicious of malignancy (primary tumor, lymph node > 10mm or with Standardized Uptake Value (SUV) > 2.5)

Exclusion Criteria:

  • Other modality then EBUS judged preferable by treating physician to obtain tumoral tissue for NGS testing

Study Plan

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of obtention of adequate material for NGS testing with 2 vs 3 passes/lymph node
Time Frame: At recruitment completion (expected time 2 years), all cell blocks will be reviewed by the blinded pathologist to assess adequacy rate for NGS testing
Cell block will be reviewed by a blinded pathologist to determine the percentage of tumor cells within the sample by increment of 5%. More than 10% of tumor cell will be considered adequate.
At recruitment completion (expected time 2 years), all cell blocks will be reviewed by the blinded pathologist to assess adequacy rate for NGS testing
Percentage of patients for which liquid biopsy allowed to identify genetic alterations not identified from tissue biopsy
Time Frame: At 1 month
A case for which liquid biopsy NGS testing allows to identify a genetic alteration not identified by matched tissue biopsy (tissue inadequate, insufficient for molecular testing or adequate but genetic alteration not found) will be considered a case for which liquid biopsy provided additional clinical findings
At 1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of obtention of adequate material for NGS testing with 2 vs 3 passes/patient
Time Frame: At recruitment completion (expected time 2 years), all cell blocks will be reviewed by the blinded pathologist to assess adequacy rate for NGS testing
Cell block will be reviewed by a blinded pathologist to determine the percentage of tumor cells within the sample by increment of 5%. More than 10% of tumor cell will be considered adequate.
At recruitment completion (expected time 2 years), all cell blocks will be reviewed by the blinded pathologist to assess adequacy rate for NGS testing
Rate of obtention of adequate material for NGS testing with 2 vs 3 passes/sampling scheme

Cell block will be reviewed by a blinded pathologist to determine the percentage of tumor cells within the sample by increment of 5%. More than 10% of tumor cell will be considered adequate.
