New antibody drug shows promise for Hard-to-Treat lymphoma

NCT ID NCT03625037

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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests an antibody called epcoritamab in 666 people with B-cell lymphoma that has come back or not responded to treatment. The drug is designed to help the immune system attack cancer cells. The study looks at safety, the right dose, and how well the drug works.

What this could mean

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

Active substance
Epcoritamab (an antibody that helps the immune system attack cancer cells)
What this could lead to
If successful, this could provide a new treatment option for people with B-cell lymphoma that has not responded to other therapies.
What could go wrong
This is an early-phase trial, so the drug may not work as hoped or could cause significant side effects like cytokine release syndrome. Results may not apply to all lymphoma types.
