Can less radiation be just as good for hodgkin lymphoma?

NCT ID NCT07256158

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 Results may not be published yet.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

Summary

This phase 3 trial is testing whether a lower dose of radiation (20 Gy) is as effective as the standard dose (30 Gy) for people with early-stage, unfavorable Hodgkin lymphoma. Only patients whose cancer shows a complete metabolic response after two cycles of chemotherapy will be included. The goal is to reduce side effects while maintaining the same level of cancer control.

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 (involved site radiotherapy)
What this could lead to
If successful, this could allow many Hodgkin lymphoma patients to receive a lower, safer dose of radiation without reducing the chance of keeping the cancer from coming back.
What could go wrong
This is a non-inferiority trial, so the lower dose might prove slightly less effective. The results apply only to patients who already had a good response to two cycles of chemotherapy, not everyone.
