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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether giving extra amino acids to critically ill patients on breathing machines helps their bodies build more protein. Researchers will measure protein balance using special tracers. The goal is to understand how nutrition affects recovery in the ICU. About 30 adults are taking part.

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 30 people

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

Started

Mar 2017

Expected to finish

Feb 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.

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

Inclusion Criteria: * Mechanically ventilated adult patients (\>18 years old) admitted to ICU with an expected ICU dependency (alive and need for mechanical ventilation * Vasopressor therapy, or mechanical circulatory support) at the point of screening of an additional 3 days, as estimated by the treating physician. Exclusion Criteria: * Patients who are moribund (expected death within 48 hours) * Expected to have life-sustaining treatments withdrawn in the next 3 days * Those with a contraindication to enteral nutrition (EN) * Already on parenteral nutrition (PN) * Those with acute fulminant hepatitis or severe chronic liver disease (Child's class C) * Patients on extracorporeal membrane oxygenation or carbon dioxide removal\* Patients with organ transplantation * Those with a broncho-pleural fistula * Patients with documented allergies to any of the study nutrients or its excipients will be excluded. * Patients requiring continuous renal replacement therapy or extracorporeal membrane oxygenation are excluded due to inability to accurately measure protein turnover.
