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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
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This status has not been confirmed recently, so it may be out of date.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 trial investigates whether adding a device that removes carbon dioxide from the blood (ECCO2R) to standard care improves survival in people with very severe flare-ups of chronic obstructive pulmonary disease (COPD). The study includes patients at high risk of needing a breathing tube or already on a ventilator. Researchers compare outcomes between those receiving standard care alone and those also receiving ECCO2R therapy.

What this could mean

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

Active substance
ECCO2R therapy using the Xenios platform (a device that removes carbon dioxide from the blood)
What this could lead to
If effective, this approach could reduce the need for invasive ventilation and lower death rates during severe COPD flare-ups.
What could go wrong
This is a very small, early-stage study with only 17 participants, so results may not apply broadly. The device carries risks like bleeding, infection, and blood clots.

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.

Inclusion Criteria: * Age ≥ 18 years * Known or suspected diagnosis of COPD based on clinical history, pulmonary function test when available, arterial blood gases, physical examination, and chest radiograph * Worsening dyspnea for \< 2 weeks * Written informed consent signed by patients or their surrogates, with possibility of an emergency procedure with deferred consent * Patient affiliated to a Social Security System (excluding "AME: aide médicale d'état") * Negative serum or urinary β-hCG for women of child-bearing potential * Very severe AE criteria defined either by: 1. Stratum 1: high likelihood of NIV failure defined by PaCO2 \> 55 mmHg and pH \< 7.25, either at baseline and/or after at least one hour of NIV 2. Stratum 2: intubation and IMV since less than 72 hrs, either after NIV failure and/or with pH \< 7.30 and PaCO2 \> 55 mmHg and PEEPi (end-expiratory occlusion) \> 5 cmH2O, while on Assist-Controlled Ventilation with the following parameters: VT: 8 ml/kg, RR: 12/min., applied PEEP: 0 cmH2O Exclusion Criteria: * Hemodynamic instability * Known allergy to heparin or to any of the excipients of the specialty used * Contra-indications to heparin listed in the SmPC of the specialty used. * History of type II Heparin-induced thrombocytopenia * Thrombocytopenia (platelets \< 100.000/mm3) * Recent major surgery * Haemorrhagic disorders such as: * Organic lesion likely to bleed * Bleeding manifestations or tendencies linked to disorders of hemostasis * Intracerebral hemorrhage * Uncontrolled arrhythmia * Bleeding diathesis * Body Mass Index \> 35 kg/m2 * PaO2/FiO2 \< 180 mmHg * Do not intubate order * Fibrosing idiopathic interstitial pneumonitis (based on the available medical files) * Neuromuscular diseases (based on the available medical files) * Patients with tracheotomy * Patients with severe concomitant chronic systemic disease with a limited probability of survival (\< 6 months) * Severely disabled (confinement to bed and inability to wash or dress alone) patients before AE * Pregnant woman * Participation in another interventional study involving human participants up to their ICU discharge, whether the studies include an investigational medical device, or being in the exclusion period at the end of a previous study.
