NCT ID NCT05867953

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a robotic system (Ion Endoluminal System) to see how accurately it can place a biopsy tool into lung nodules. 200 adults with lung nodules between 6 mm and 3 cm took part. The system uses real-time 3D imaging to guide the biopsy needle. The main goal was to measure how often the tool reached the nodule directly before sampling.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Robotic navigational bronchoscopy system with real-time 3D imaging
What this could lead to
If successful, this could improve the accuracy of lung biopsies, leading to better diagnosis of lung cancer with fewer complications.
What could go wrong
This is a completed device study, not a treatment trial. It only measures tool placement accuracy, not patient outcomes. Results may not change standard care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patient is aged 18 years or older at time of consent. 2. Patient is suitable for elective nodule biopsy via bronchoscopy under general anesthesia per Investigator's discretion. 3. Patient has solid or semi-solid pulmonary nodule(s) of ≥6 mm and ≤3 cm in largest dimension (based on pre-procedure CT scan). 4. Pulmonary nodule(s) intended for biopsy during the study procedure is (are) located at least 4 (≥4) airway generations out (trachea = generation 0, e.g. subsegmental bronchi or beyond) based on pre-procedure CT scan. 5. Patient has a moderate to high risk of lung cancer based on clinical, demographic, and radiologic information or with suspected metastatic disease. High risk for malignancy patients are eligible if a biopsy is required or requested prior to intervention. 6. Patient is willing and able to give written informed consent for Clinical Investigation participation. 7. Patient is not legally incapacitated or in a legal/court ordered institution. Exclusion Criteria: 1. Patient has a lack of fitness or exercise capacity to undergo bronchoscopy under general anesthesia as determined by Investigator prior to procedure. 2. Patient with type 1 pure ground glass opacity target nodule(s) intended for biopsy during study procedure. 3. Presence of mediastinal or hilar lymphadenopathy requiring tissue biopsy on pre-procedure CT or positron emission tomography (PET)-CT scan. 4. Patient with American Society of Anesthesiologists Classification (ASA) ≥4. 5. Patient underwent a pneumonectomy. 6. Any invasive concomitant procedure not related to the pulmonary nodule(s) or suspected disease state. 7. Female patient of child-bearing potential who is unable to take adequate contraceptive precautions or is known to be pregnant, and/or breast feeding. 8. Patient has a documented medical history of uncorrectable coagulopathy, bleeding, or platelet disorder. 9. Patient is taking antiplatelet or anticoagulant medications that cannot be stopped per standard practice. 10. Patient is currently participating or has participated in another Clinical Investigation within the past 30 days, such as interventional trials or trials with experimental agents or agents of unknown risk, that may affect the endpoints of this Clinical Investigation. 11. Investigator, in their professional opinion, has decided that it is in the patient's best interest to not participate in the Clinical Investigation. 12. Patient is not willing to comply with post study procedure participation requirements.
