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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether people with early-stage lung cancer (stage IA2 to II) who have no detectable cancer DNA in their blood after surgery can safely skip additional treatments like chemotherapy. Instead, they would be closely monitored with regular blood tests and scans. The trial will compare this 'adaptive therapy' approach to standard care to see if it leads to similar survival rates while reducing side effects.

What this could mean

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

Active substance
standard therapy (chemotherapy, immunotherapy, or targeted therapy)
What this could lead to
If successful, this could show that some early-stage lung cancer patients can safely avoid chemotherapy and its side effects by relying on close monitoring.
What could go wrong
This is an early-stage study (Phase NA) with only 286 participants. The approach may not be safe for all patients, and there is a risk that cancer could return without treatment.

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

About 286 people

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

Started

Expected to finish

Dec 2029

An estimate. End dates often move.

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.

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: * Stage IA2-II non-small cell cancer patients who after complete resection. * Two-round MRD tests confirm landmark undetectable MRD * Expected survival ≥24 months * ECOG PS 0-1 * Willing to accept MRD monitoring every 3 months for a total of 2 years after surgery Exclusion Criteria: * Patients who had previously undergone radiotherapy or chemotherapy or any other anti-tumor therapy * Patients with a history of other malignancies in the past 5 years * Any unstable systemic disease (eg, active infection, high-risk hypertension, unstable angina, congestive heart failure, etc.) or other conditions that investigators considered would limit the ability of the patient to participate in the study
