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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether a balloon device, called REBOA, can be safely used by emergency teams outside a hospital to improve blood flow in people whose heart has stopped (cardiac arrest). The balloon is inserted into the main artery and inflated to redirect blood to the heart and brain. Researchers will check if the procedure is possible and if it helps blood pressure during CPR. The study involves 40 adults in the East of England.

What this could mean

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

Active substance
ER-REBOA catheter (a balloon device inserted into the aorta to block blood flow)
What this could lead to
If successful, this could show that using a balloon to redirect blood flow during cardiac arrest is possible and may improve chances of survival.
What could go wrong
This is a very early feasibility study with only 40 participants. The procedure is experimental and may not work or could cause complications like vessel damage.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 40 people

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

Started

Jun 2024

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 80 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion criteria * Non-Traumatic OHCA in patients within the East of England area AND with a East Anglian Air Ambulance (EAAA) REBOA team in attendance * Patients below or equal to 80yrs of age and above or equal to 18yrs of age, according to available information/estimate at scene * No flow \<10 mins from data available (i.e. total period in OHCA with no CPR) * In cardiac arrest (with no sustained ROSC) on arrival of the EAAA REBOA team Exclusion criteria * Patients aged less than 18 or above 80 years * Known terminal illness * Multiple severe co-morbidities * Traumatic Cardiac Arrest (TCA) * Inability to deploy mechanical CPR (e.g. LUCAS Device) * Pregnancy, obvious or suspected
