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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 phase III trial compares a shorter course of radiation therapy (hypofractionated) against the standard longer course for people with cervical cancer. Both groups also receive chemotherapy and brachytherapy. The goal is to see if the shorter schedule controls the cancer just as well while being more convenient for patients.

What this could mean

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

Active substance
hypofractionated chemoradiotherapy (radiation given in fewer, larger doses)
What this could lead to
If successful, this approach could offer a more convenient and equally effective treatment option for cervical cancer, reducing the number of hospital visits needed.
What could go wrong
This is a single phase III trial; results may not confirm that the shorter schedule is as safe or effective as the standard one, and there may be unknown long-term side effects.
