What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a special lung MRI, combined with a computer-generated CT-like image, can accurately detect lung cancer in heavy smokers. Participants are 55–74 years old with a solid lung nodule found on a prior scan. The goal is to see if this non-invasive method can reduce false alarms and the need for risky biopsies.

What this could mean

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

Active substance
multiparametric MRI and synthetic CT
What this could lead to
If successful, this approach could offer a safer, non-invasive way to monitor lung nodules and reduce unnecessary biopsies in high-risk smokers.
What could go wrong
This is a small pilot study (50 people) at a single center, so results may not apply broadly. MRI may miss some nodules or yield false positives.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 50 people

The number the study aims to enrol. It can still change while the study runs.

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

Inclusion Criteria: * Subject aged between 55 and 74 years * High risk of developing lung cancer: by a combination of exposure to lung carcinogens and smoking (exposure to tobacco at the rate of 30 packs/year or cessation \< 15 years) * Presence of at least one lung solid nodule ≥ 5mm on the initial scan. * Subject able and willing to complete all scheduled visits and assessments. * Subject with health insurance. * Signed informed consent. Exclusion Criteria: * Subject with signs of lung cancer * Subject with history of lung cancer * Presence of severe life-threatening comorbidities at 6 months (recent CVA, recent discovery of advanced stage cancer) * Subject who had already undergone a chest scan less than a year previously * No exposure to occupational lung carcinogens according to the predefined criteria. * No exposure to tobacco or insufficient exposure to tobacco or cessation \> 15 years. * Contra-indication to MRI (Pace maker, implants, claustrophobia…) * Pregnant or breastfeeding woman * Poor understanding of French * Subject under legal protection
