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
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 This study
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 Results may not be published yet.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

Summary

This phase 3 trial tested whether giving only radiation therapy works as well as radiation plus chemotherapy for people with intermediate-risk nasopharyngeal cancer. The study enrolled 338 participants and used modern intensity-modulated radiation therapy (IMRT). The goal was to see if skipping chemotherapy could reduce side effects without harming treatment success.

What this could mean

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

Active substance
Cisplatin chemotherapy plus intensity-modulated radiation therapy (IMRT)
What this could lead to
If successful, this could show that radiation alone is enough for intermediate-risk nasopharyngeal cancer, sparing patients from chemotherapy side effects.
What could go wrong
This is a completed phase 3 trial, but results may not apply to all patients or settings. The chemotherapy regimen used is intensive and may cause significant side effects.
