NCT ID NCT05878184

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early-phase study tests SC291, a CAR T-cell therapy made from donor cells, in 16 adults with relapsed or refractory B-cell non-Hodgkin lymphoma or chronic lymphocytic leukemia. The goal is to check safety and see if the treatment can shrink tumors. Because it uses donor cells, it could be available faster than personalized therapies, but it also carries risks of immune reactions.

What this could mean

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

Active substance
SC291 (a type of CAR T-cell therapy made from donor cells)
What this could lead to
If it works, this could provide a new treatment option for people with hard-to-treat blood cancers who have run out of standard therapies.
What could go wrong
This is a very early (Phase 1) trial with only 16 participants, so safety and effectiveness are not yet proven. There are risks of serious side effects like cytokine release syndrome or immune reactions.
