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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This early-phase trial tests a two-step treatment for adults with B-cell acute lymphoblastic leukemia (B-ALL) who cannot have a standard donor stem cell transplant. First, patients receive the drug blinatumomab to clear any remaining cancer cells, then they undergo their own stem cell transplant (autologous HSCT). The goal is to see if this 'sandwich' approach is safe and can reduce relapse rates while avoiding the high risks of donor transplants. Only 4 participants are being enrolled.

What this could mean

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

Active substance
blinatumomab
What this could lead to
If this works, it could offer a safer consolidation option for B-ALL patients who cannot have a donor transplant, potentially reducing relapse without the high risks of donor transplants.
What could go wrong
This is a very early Phase 1 trial with only 4 participants, so results may not apply broadly. The combination approach is new and may still carry risks of relapse or side effects.
