NCT ID NCT07765966

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 This study
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 Results may not be published yet.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-stage trial is testing an experimental therapy called RXIM002 in adults with relapsed or refractory autoimmune cytopenias, including immune thrombocytopenia (ITP). The therapy uses a special RNA molecule to instruct the body to produce CAR T cells that target and potentially calm the immune cells attacking blood cells. The study aims to evaluate the safety, tolerability, and preliminary effectiveness of this approach.

What this could mean

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

Active substance
RXIM002, an experimental RNA-based therapy that instructs the body to make CAR T cells targeting CD19
What this could lead to
If successful, this could lead to a new treatment option for people with autoimmune cytopenias that have not responded to standard therapies.
What could go wrong
This is an early-phase trial with a small number of participants, so safety and effectiveness are not yet established. There are risks of side effects, and the therapy may not work for everyone.
