What is being measured

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

  1. length of invasive mechanical ventilation

    Measured: within the first 28 days after intubation

Secondary outcomes (5)
  1. Length of weaning from mechanical ventilation

    data retrieved once, at the extubation or at the end of invasive ventilation in the tracheotomy

    Measured: once at the extubation or at day 28

  2. weaning success

    Data collected once at the end of ICU stay or at Day 28

    Measured: once at the end of ICU stay or at Day 28

  3. numbers of nosocomial infections

    data retrieved every day, until extubation or at the end of invasive ventilation in the tracheotomy

    Measured: every day during 28 days

  4. length of ICU stay

    Data collected once at the end of ICU stay or at Day 28

    Measured: once at the end of ICU stay or at Day 28

  5. ICU mortality

    Data collected once at the end of ICU stay or at Day 28

    Measured: once at the end of ICU stay or at Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Acetazolamide in people with Decompensated Chronic Obstructive Pulmonary Disease, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 1 inclusion and 0 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: finished, as of the sponsor's last update on 6 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

length of invasive mechanical ventilation (time frame: within the first 28 days after intubation). 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 NCT01627639, which also lists 3 linked publications.

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 6 Oct 2015.
