A sharper eye on lung cancer: could PET scans and blood tests outsmart relapse?

NCT ID NCT03740126

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether using whole-body PET/CT scans and liquid biopsies (blood tests that detect cancer DNA) can improve the follow-up care of people who have completed treatment for early-stage non-small cell lung cancer. The goal is to see if these advanced tools can find any returning cancer sooner and more often when it is still treatable, compared to standard CT scans alone. Participants will be randomly assigned to either the experimental surveillance schedule or the standard one, and their outcomes will be compared.

What this could mean

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

Active substance
Whole-body FDG-PET/CT imaging and liquid biopsy blood tests
What this could lead to
If successful, this could lead to a more effective surveillance strategy that detects lung cancer recurrences earlier, potentially improving survival and quality of life.
What could go wrong
The trial is exploratory and may not show a clear benefit. PET/CT scans can produce false positives, leading to unnecessary procedures, and liquid biopsies are still being validated for routine use.

Study facts

What this study's own registry entry says, in plain language.

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

750 people

The number who actually took part.

Started

Oct 2018

Finished

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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 non-small cell lung cancer (NSCLC), proven by cytology or histology * Patient in clinical stages I-III * Age≥ 18 years * Performance status ≤ 2 at the time of referral to therapy * Patient referred for definitive treatment (e.g. surgery, surgery followed by adjuvant chemotherapy, concomitant radio-chemotherapy, conventional or stereotactic radiotherapy or radiofrequency ablation). * Patient has given his/her written informed consent before any specific procedure from protocol Exclusion Criteria: * Patient, whose disease has progressed within the first 3 months after cancer treatment, e.g. confirmed progressive disease on CT. * Persons deprived of liberty or under guardianship or curators * Dementia, mental alteration, severe psychiatric disease or other circumstances that can compromise informed consent from the patient and/or adherence to the protocol and the monitoring of the trial * Pregnant or breastfeeding women * Patient participating in another interventional study during the surveillance period. This is only relevant for studies that might interfere with the intervention, whereas studies on late effects will not preclude participation in SUPE-R. Participation in protocols related only to initial treatment will not preclude participation in SUPE-R. Cases of doubt will be settled by the steering committee.
