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
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study compares a step-by-step protocol for stopping high-flow nasal oxygen therapy against usual doctor-led care in 148 adults with acute respiratory failure. The protocol uses oxygen levels and breathing rate to decide when to stop. The goal is to see if a standard approach reduces the chance of needing to restart oxygen or move to a breathing machine.

What this could mean

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

Active substance
high-flow nasal therapy weaning protocol
What this could lead to
If successful, this could establish a standard way to safely stop high-flow oxygen therapy, reducing hospital stays and preventing breathing setbacks.
What could go wrong
This is a small, early-stage trial (148 participants) testing a process, not a new drug. The protocol may not work better than doctors' judgment, and results may not apply to all patients.

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 148 people

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

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

May 2028

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: * Age ≥18 years * Presence of acute respiratory failure (ARF) * Receiving HFNC treatment for ≥24 hours Exclusion Criteria: * Post-extubation HFNC use or tracheostomized patients * Respiratory acidosis (pH \<7.35) or clinically significant acute hypercapnia (pCO₂ \>50 mmHg with worsening from baseline) * Long-term home NIV or home CPAP use * Do-not-intubate (DNI) orders precluding escalation to invasive mechanical ventilation * Life expectancy ≤48-72 hours due to terminal non-respiratory disease * Neurological impairment or deep sedation preventing safe HFNC use (e.g. coma or severe uncontrolled delirium) * Technical contraindications to HFNC (i.e. facial trauma, maxillofacial surgery, severe nasal obstruction) * Refusal to participate or inability to provide informed consent
