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 Results may not be published yet.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 study tests a new treatment called rondecabtagene autoleucel (ronde-cel) for people with aggressive B-cell non-Hodgkin lymphoma that has come back or not responded to prior therapy. Ronde-cel is a CAR T-cell therapy that targets two proteins (CD19 and CD20) on cancer cells. The trial has two phases: Phase 1 checks safety and the right dose, and Phase 2 measures how well it works. About 270 adults will take part across multiple centers.

What this could mean

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

Active substance
Rondecabtagene autoleucel (ronde-cel), a CAR T-cell therapy that targets two proteins (CD19 and CD20) on lymphoma cells, given with conditioning chemotherapy (fludarabine and cyclophosphamide)
What this could lead to
If successful, this could offer a new treatment option for people with aggressive B-cell lymphoma that has not responded to other therapies.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants, so results may not apply to everyone. CAR T-cell therapies can cause serious side effects like cytokine release syndrome and neurological problems.
