NCT ID NCT07621471

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This early-phase trial tests a new type of immune cell therapy for people with advanced solid tumors that have not responded to standard treatments. The therapy uses a patient's own natural killer (NK) cells that have been genetically modified to produce IL-15, a protein that helps them survive and fight cancer longer. The study will enroll 12 participants to check safety and find the right dose.

What this could mean

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

Active substance
genetically engineered natural killer (NK) cells that produce IL-15
What this could lead to
If it works, this could point toward a new treatment option for people with hard-to-treat solid tumors that have spread.
What could go wrong
This is a very early, small trial (12 people) focused on safety, not effectiveness. The treatment may not shrink tumors or could cause serious side effects.
