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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is a large registry that tracks cancer patients who receive both radiotherapy and molecular therapies, such as immunotherapy. The goal is to better understand how these two treatments interact and to identify how often severe side effects occur. By collecting data from thousands of patients, researchers hope to improve safety and guide future treatment decisions.

What this could mean

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

Active substance
Radiotherapy combined with molecular therapies (immunotherapy or signaling pathway modulators)
What this could lead to
If successful, this could lead to better prediction and management of severe side effects in cancer patients receiving combined radiotherapy and immunotherapy, improving treatment safety.
What could go wrong
This is an observational registry, not a treatment trial, so it won't directly test a new therapy. Results depend on real-world data and may not capture all variables affecting side effects.
