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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Adults with B-cell acute lymphoblastic leukemia that has come back or stopped responding to treatment have few options. This phase 2 trial tests whether adding epratuzumab, an antibody that attaches to the CD22 protein found on most of these leukemia cells, to standard chemotherapy can improve the chance of a complete response. Researchers will give participants either an intensive chemotherapy regimen called HyperCVAD or a gentler combination of vincristine and dexamethasone, depending on their age and fitness, along with epratuzumab. The main goal is to see how many patients achieve a complete remission, which could make them eligible for a stem cell transplant.

What this could mean

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

Active substance
epratuzumab, an antibody that targets the CD22 protein on leukemia cells, added to chemotherapy
What this could lead to
If it works, this combination could help more adults with relapsed or refractory B-ALL reach a second remission and become eligible for a potentially curative stem cell transplant.
What could go wrong
This is a phase 2 trial in a small group of very sick patients, so it may not improve remission rates or survival. Adding epratuzumab to intensive chemotherapy could also cause serious side effects, including infections and low blood counts.
