NCT ID NCT03005743

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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 large phase III trial tested whether using MRI scans to guide internal radiation (brachytherapy) works better than the traditional X-ray method for women with locally advanced cervical cancer. Over 1,000 participants received either MRI-based or X-ray-based brachytherapy. The goal was to see if MRI guidance improves tumor control and reduces severe 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
radiation therapy (brachytherapy)
What this could lead to
If MRI-guided brachytherapy proves better, it could become the new standard for treating locally advanced cervical cancer, offering better tumor control and fewer long-term side effects.
What could go wrong
This trial is completed but results are not yet widely implemented. MRI-guided brachytherapy requires specialized equipment and training, so it may not be available everywhere. Also, individual results vary.
