About this study

Official title: An International Phase III Randomised Trial Comparing in Severe Exacerbations of Chronic Obstructive Pulmonary Disease the Efficacy of Helium/Oxygen Versus Air/Oxygen Administered During Spontaneous Breathing and Intermittent Non-Invasive Ventilation.

The primary objective of the study is to evaluate the efficacy of Helium/Oxygen (He/O2) 78%/22% compared to a conventional Air/O2 mixture in reducing endotracheal intubation rate and mortality in patients with severe hypercapnic exacerbations of Chronic Obstructive Pulmonary Disease (COPD) during their index Intensive/Intermediate Care Unit (ICU) stay.

Read the detailed description

Patients eligible for this study are critically ill patients with COPD admitted in Intensive Care Unit for an exacerbation of their chronic disease with hypercapnic acute respiratory failure. The patients will receive an Helium/Oxygen mixture or an Air/Oxygen mixture for a maximum of 72 hours during Non-Invasive Ventilation (NIV) and NIV-free sessions.

During NIV sessions, gas mixtures will be administered using a ventilator suitable for NIV with either He/O2 or Air/O2 and a NIV facemask.

Patients will be followed until hospital discharge and then contacted by phone up to the 6th month after randomization.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Helium/Oxygen 78%/22%Drug

    The Helium/Oxygen mixture will be administered during NIV and NIV-free sessions for a maximum of 72 hours using study dedicated devices.

    Patients will then receive the Air/Oxygen mixture with usual devices.

  • Air/OxygenDrug

    The Helium/Oxygen mixture will be administered during NIV and NIV-free sessions for a maximum of 72 hours using study dedicated devices.

    Patients will then receive the Air/Oxygen mixture with usual devices.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Reduction of NIV failure

    Endotracheal intubation and/or death

    Measured: 10 days (average)

Secondary outcomes (7)
  1. Duration of ICU stay and duration of index hospitalisation

    Measured: 10 days (average)

  2. Duration of invasive ventilation

    Measured: 10 days (average)

  3. Adverse events

    Measured: 6 months (post-randomization)

  4. Medico-economic parameters

    Overall costs and cost-effectiveness

    Measured: 6 months

  5. Physiological and laboratory parameters

    Systolic and diastolic blood pressures, heart rate, central body temperature, arterial oxygen saturation, haematology and serum biochemistry

    Measured: 10 days (average)

  6. Duration of NIV sessions

    Cumulative daily duration of NIV sessions and their number during each of the 3-day treatment period and globally

    Measured: 10 days (average)

  7. Time interval between the discharge of the index ICU stay and the first re-admission in ICU for severe exacerbation of COPD

    Measured: 6 months (post-randomization)

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted1 Jul 2010 (estimated)
  2. Study startMay 2010
  3. Primary completionOct 2013
  4. Study completionJun 2014

Why it stopped: the observed event rate is lower than expected by the protocol hypothesis.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Helium/Oxygen 78%/22% and Air/Oxygen in people with Chronic Obstructive Pulmonary Disease, run by Air Liquide Santé International at 16 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in France, Belgium, Tunisia, Italy, Switzerland and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: the observed event rate is lower than expected by the protocol hypothesis.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reduction of NIV failure (time frame: 10 days (average)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01155310, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2014.
