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

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 Results may not be published yet.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.

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.

Summary

This study tests a procedure called EUS-guided radiofrequency ablation (RFA) for solid tumors in the stomach, liver, kidney, or adrenal glands. It involves using an endoscope to insert a needle that heats and destroys tumor tissue. The study will enroll 30 adults who cannot have surgery, to see if the procedure is safe and works.

What this could mean

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

Active substance
radiofrequency ablation (RFA) delivered via endoscope
What this could lead to
If successful, this could offer a less invasive treatment option for people with solid abdominal tumors who cannot have surgery.
What could go wrong
This is a small early study (30 people) focused on safety. The procedure may cause side effects like pancreatitis or thermal injury, and it is not yet proven to be effective long-term.
