Experimental immune cell therapy for liver cancer hits early roadblock

NCT ID NCT04502082

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
The trial has finished. Results may not be published yet.
Stopped early This study
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This status has not been confirmed recently, so it may be out of date.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-stage trial tested a new type of immune cell therapy (ET140203 T cells) in 8 adults with advanced liver cancer that had not responded to other treatments. The therapy was designed to target a protein called AFP found on cancer cells. The study was terminated early, so we have very limited information on safety or effectiveness.

What this could mean

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

Active substance
engineered immune cells (ET140203 T cells)
What this could lead to
If this approach had worked, it could have pointed toward a new treatment option for people with advanced liver cancer who have run out of standard therapies.
What could go wrong
This was a very early, small trial that was terminated before completion. The therapy may not be effective or safe enough, and it is unclear if it will ever be tested further.
