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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 checking for pieces of tumor DNA in the blood (called ctDNA) can help doctors see how well treatment is working and find cancer returning early in children with neuroblastoma. About 200 children with newly diagnosed or returning neuroblastoma will give blood samples during their regular care. The goal is to learn if this blood test matches what scans and other tests show about the cancer's status.

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

Inclusion Criteria: * Patients with histologically or clinically confirmed neuroblastoma according to institutional or protocol-defined diagnostic criteria. Newly diagnosed, relapsed, refractory, or progressive neuroblastoma eligible for serial biospecimen collection during routine clinical care. Availability of peripheral blood samples for ctDNA/MRD analysis at baseline and/or longitudinal follow-up time points. Availability of clinical data required for molecular-clinical correlation analyses, including response and outcome assessment. Availability of tumor tissue and matched control samples for tumor-informed assay development, if applicable and feasible. Written informed consent from a parent or legal guardian, and assent from the participant when applicable. Exclusion Criteria: * Inability to provide protocol-required blood samples for ctDNA/MRD testing. Insufficient clinical information for protocol-defined response or outcome analyses. Poor-quality or insufficient biospecimens that preclude molecular analysis, when molecular testing is a required component of the study dataset. Any condition that, in the opinion of the investigator, would make study participation inappropriate.
