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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether adding radiation to the chest can help people with extensive-stage small-cell lung cancer, a type of lung cancer that has spread widely. Participants first receive standard chemotherapy plus an immunotherapy drug, and if their cancer does not worsen, they then receive chest radiation alongside continued immunotherapy maintenance. The study aims to see if this combination can delay cancer progression and improve overall survival, while also monitoring 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
thoracic radiotherapy (radiation to the chest)
What this could lead to
If it works, adding chest radiation could help control extensive-stage small-cell lung cancer longer, potentially improving survival when combined with standard chemo-immunotherapy and maintenance treatment.
What could go wrong
This is a single-arm, early-phase trial without a comparison group, so results may not be definitive. Radiation to the chest can cause side effects like fatigue, lung irritation, or difficulty swallowing.

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 104 people

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

Started
