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 This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two types of breathing muscle training in people who have had a lung transplant. One group does standard constant-resistance exercises, while the other adds short bursts of harder effort. The goal is to see which method better improves breathing strength and daily function over the first six months after transplant. About 42 adults will take part.

What this could mean

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

Active substance
inspiratory muscle training (breathing exercises) using either constant resistance or intermittent variable resistance
What this could lead to
If successful, this could point to a better breathing exercise program for lung transplant patients, helping them recover more strength and function.
What could go wrong
This is a small, early-stage trial with only 42 participants, so results may not apply to all patients. The training is safe but may not show a clear benefit over standard care.

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 42 people

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

Started

Expected to finish

Dec 2027

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.

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: * Adult patient (≥18 years) who has undergone lung transplantation (single-lung or double-lung) at our center. * Alert and cooperative (Glasgow Coma Scale \>13 points). * Hemodynamically stable (blood pressure between 90/60 and 165/90 mmHg; heart rate between 60 and 130 beats per minute). * No disabling dyspnea at rest (maintained at mild levels according to the Borg scale or NYHA class I-II), even if requiring supplemental oxygen with a saturation \>89%. * No limiting chest pain interfering with respiratory therapy. Exclusion Criteria: * Patients unable to cooperate with treatment due to lack of necessary instrumental cognitive skills. * Perceived non-adherence to pharmacological and non-pharmacological treatment by healthcare personnel. * Need for continuous non-invasive mechanical ventilation, high-flow oxygen therapy, or Venturi mask. * Patients with significant neurological disorders, severe polyneuropathies, or stroke (CVA). * Presence of tracheostomy, active hemoptysis, bronchial suture dehiscence. * Significant air leak with clinical repercussions. * Any clinical condition that, in the investigator's judgment, poses a risk to the patient.
