Study summary

This pilot early phase I trial studies how well real-time optical biopsy works in improving lung cancer diagnosis in patients undergoing lung biopsy. Real-time optical biopsy using confocal microscopy may improve the ability of physicians to diagnose lung cancer and accurately differentiate cancerous and benign lesions found during computed tomography screening.

Read the detailed description

PRIMARY OBJECTIVES:

I. Show that it is possible to distinguish lung cancer from benign lesions in ex vivo tissue samples using optical microscopy.

II. Test a proof-of-concept endoscopic instrument for imaging through a biopsy needle under computed tomography (CT) guidance on ex vivo tissue samples.

OUTLINE:

Patients undergo extraction of up to 3 additional lung biopsies from target lesions that are at least 2-3 cm in diameter using the 19 gauge SuperCore biopsy needle or the 20 gauge Rotax needle. The extracted tissue is imaged via confocal fluorescence microscopy using a variety of fluorescent contrast agents, such as, fluorescein sodium, methylene blue, or indocyanine green and then undergo hematoxylin and eosin processing.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participants will be drawn from the pool of patients who have suspicious lesions identified on CT and who are already scheduled for a lung procedure with Dr. Woodhead or one of his colleagues
  • Patients will be asked to consent to 2 to 3 extra biopsy samples to be used for this research project

Exclusion criteria

Exclusion Criteria:

  • Excluded from this study will be minors below age 18, prisoners, pregnant women, patients with a for additional lung , and patients who cannot give (language barrier, cognitive impairment, etc.)
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Diagnosis of ex vivo tissue samples for lung cancer or benign lesions using optical microscopy

    The aim is to show that it is possible to distinguish lung cancer from benign lesions in ex vivo tissue samples using optical microscopy.

    Time frame: At the time of biopsy

  2. Imaging of ex vivo tissue samples using an endoscopic instrument

    A proof-of-concept endoscopic instrument will be tested for imaging through a biopsy needle under computed tomography guidance on ex vivo tissue samples.

    Time frame: At the time of biopsy

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2017 to primary completion in Apr 2022, 57 months.

Of 864 non-industry interventional studies with no phase under Lung Neoplasms, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 68. This study's 57 months is above that.

Counting every sponsor, half of 915 studies reached it within 34 months; a quarter within 15 and three quarters within 67.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 1, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
