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.

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 Results may not be published yet.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

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 tested whether a negative pressure suction device placed in the throat could reduce aspiration (food or liquid entering the airway) during swallowing exams in people with severe swallowing problems. Only one person participated, and the device was inserted through an existing gastrostomy tube. The goal was to see if suction could safely lower the risk of aspiration.

What this could mean

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

Active substance
Negative pressure suction catheter (Foley catheter placed through gastrostomy site)
What this could lead to
If it works, this could offer a new way to reduce aspiration risk during swallowing for patients with severe swallowing problems.
What could go wrong
This was a very small study with only one participant, so results may not apply to others. The device requires a gastrostomy tube, limiting who can use it.
