NCT ID NCT07523464

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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early-phase study tests whether giving a small, focused dose of radiation to the center of a lung tumor can safely 'prime' the immune system before standard chemoradiation and immunotherapy. About 24 adults with stage III non-small cell lung cancer that cannot be removed by surgery will take part. The main goal is to check for serious side effects and see if this approach can be smoothly added to usual care.

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

Inclusion Criteria: * Age 18 to 75 years; * Histologically or cytologically confirmed NSCLC; * Unresectable stage III disease according to the AJCC 8th edition; * Negative for driver gene alterations; * Considered suitable for definitive cCRT by MDT discussion or investigator judgment; * ECOG performance status 0-1; * Presence of a clearly delineable pulmonary primary lesion allowing centrally confined priming treatment planning; * Adequate major organ function as required by the study; * Willingness to participate and provision of written informed consent. Exclusion Criteria: * Presence of distant metastasis; * Positive driver gene alterations; * Prior definitive thoracic radiotherapy or prior systemic antitumor treatment for the current disease; * Active autoimmune disease or need for long-term systemic immunosuppressive therapy; * Active interstitial lung disease, prior severe radiation pneumonitis, or immune-related pneumonitis; * Special primary tumor location such that safety constraints for centrally confined priming radiotherapy cannot be met; * Primary lesion immediately adjacent to the main bronchus, carina, major vessels, or esophagus, such that the investigator judges the lead-in intervention to be excessively risky; * Pregnancy or lactation; * Any other condition that, in the opinion of the investigator, makes the patient unsuitable for this study.
