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 Results may not be published yet.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

Summary

This study tests a specially designed suction tube that cleans deep throat secretions under direct laryngoscope guidance. The goal is to see if it reduces pneumonia within 28 days in stroke patients who have trouble swallowing or coughing. Participants are adults with acute ischemic stroke and a low level of consciousness who do not already have a breathing tube.

What this could mean

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

Active substance
Oropharyngeal flushing suction tube
What this could lead to
If effective, this device could reduce pneumonia and improve survival in stroke patients with impaired swallowing.
What could go wrong
This is a small, early-stage trial. The device may not lower pneumonia rates or could cause discomfort or injury during use.

Participants

About 120 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Jul 2029

An estimate. End dates often move.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Confirmed acute ischemic stroke by cranial CT or MRI. 2. Age 18 years or older. 3. Glasgow Coma Scale score of 6 to 12. 4. No artificial airway and no requirement for invasive mechanical ventilation at enrollment. 5. Written informed consent provided by the participant or legally authorized representative. Exclusion Criteria: 1. Existing artificial airway or invasive mechanical ventilation at ICU admission or screening. 2. Pre-existing pulmonary infection at enrollment, or definite extra-pulmonary organ or tissue infection during the study period. 3. Hemorrhagic blood disorder, clinically significant coagulopathy, or bleeding risk precluding laryngoscopy. 4. Oral or maxillofacial deformity impeding laryngoscope insertion. 5. Cervical spine fracture, atlantoaxial instability, or other condition restricting neck extension or movement. 6. Confirmed or suspected pregnancy. 7. Irreversible critical illness with anticipated survival less than 28 days. 8. Uncontrolled hypertension or recurrent malignant arrhythmias. 9.
