NCT ID NCT06173518

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 Results may not be published yet.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.

Summary

This early-phase trial is testing a new CAR T-cell therapy called AUTO1 (obe-cel) in up to 30 children with B-cell acute lymphoblastic leukemia or B-cell non-Hodgkin lymphoma that has returned or not responded to treatment. The therapy uses the child's own immune cells, which are modified in a lab to recognize and attack cancer cells. The main goals are to check safety and see how many children achieve complete remission within three months.

What this could mean

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

Active substance
AUTO1 (Obecabtagene autoleucel [Obe-cel]) - a type of CAR T-cell therapy made from the patient's own immune cells
What this could lead to
If successful, this could offer a new treatment option for children with hard-to-treat B-cell cancers that have come back or not responded to standard therapy.
What could go wrong
This is an early-phase trial with only 30 participants, so results may not apply to all patients. CAR T-cell therapy can cause serious side effects like cytokine release syndrome and low antibody levels.
