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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study compares two ways to perform a lung biopsy for people with undetermined interstitial lung disease. One method uses a breathing tube and deep anesthesia (standard), while the other uses only mild sedation and numbing medicine. The goal is to see if the gentler method gives biopsy samples that are just as good for making a clear diagnosis. Only 24 adults will take part, and the study focuses on how confident pathologists are in their diagnosis from the tissue samples.

What this could mean

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

What this could lead to
If successful, this could show that a less invasive anesthesia method (NIVATS) provides equally good biopsy samples for diagnosing lung diseases.
What could go wrong
This is a very small pilot study with only 24 participants, so results may not apply widely. The main goal is to compare biopsy quality, not to test a new treatment.

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

Inclusion Criteria: * Patient with purported interstitial lung disease * Patient requiring a surgical lung biopsy to reinforce diagnosis according to current recommendations and validated by a multidisciplinary assessment * Minimum age: 18 years Exclusion Criteria: * Contra-indication for surgery * Uncontrolled oesophageal gastric reflux despite optimal treatment * Thoracic deformation (For example, pectus excavatum/carinatum or major scoliosis) * Risk of pleural adhesion (For example, patient who has already undergone thoracic surgery) * History of abnormal bleeding * Predictable risk of difficult intubation * Body mass index (BMI) \> 30 * Severe cardiovascular comorbidity (For example, instable ischemic cardiomyopathy) * Unable to comply with all trial procedures/visits (For example, language barriers, upcoming move of household to another region, unwillingness to schedule the required followup visits.) * Protected populations according to the French Public Health Code Articles L1121-5,6,8 (For example, pregnant, parturient or lactating women, prisoners, adults under guardianship or otherwise unable to consent.) * Potential interference from another study (The patient is participating in another interventional study, or has done so in the past month, or is affected by an exclusion period stipulated by a previous study.) * Non-beneficiary of the French single-payer national medical insurance system * Lack of signed informed consent
