About this study

Official title: A Single Site,Exploratory,Phase I/II,Randomised Trial Comparing the Effect of He/O2 Mixtures(He/O2 78:22 and He/O2 65:35) to Medical Air on Pulmonary Function in Moderate/Severe Asthma and COPD Patients and Healthy Volunteers

This clinical trial will include healthy volunteers, COPD patients and asthmatic patients who will breathe He/O2 78:22, He/O2 65:35 and medical air consecutively in a randomised order.

Read the detailed description

Two types of measurements will be performed with each of the three evaluated gases:

  • pulmonary function measurements at rest to establish the resistance to airflow in a reproducible way, including the measurements of Inspiratory Capacity (IC), Forced Expiratory Volume in 1 second (FEV1), Forced Expiratory Flows (FEF) at different lung volumes (25 to 75% of the vital capacity), and Forced Vital Capacity (FVC),
  • Tidal Volume (TV) measured at rest and during light cycling exercise. The results of this study should be useful to evaluate the extent of influence on gas concentration, since none of the previous trials have been performed with He/O2 65:35, as well as the extent of influence on the lung disease, since none of the previous trials have been performed with asthmatic patients at various disease stages.

The working hypothesis is that when using He/O2 mixtures 78:22 and 65:35, the flow resistance decreases as compared to medical air because low density helium replaces nitrogen, thus resulting in a lower workload of breathing for asthmatic and COPD patients. For patients with reduced pulmonary function, this difference might result in greater Inspiratory Capacity.

That is why Inspiratory Capacity will be measured as primary efficacy criterion, but also Tidal Volume and other pulmonary function parameters on 3 types of subjects/patients :

  • healthy volunteers,
  • patients with moderate and severe persistent asthma,
  • patients with moderate and severe COPD.

What participants receive

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

  • spirometerDevice

    Also called ergospirometer

    According to the randomisation order, the appropriate medical gas cylinder with the pressure regulator will be connected to a humidifier to avoid the inhalation of very dry gas; the humidifier will be connected to the breathing bag; the flow of the medical gas will be adjusted individually for each subject/patient by the valve of the pressure regulator.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing spirometer in people with Asthma and Chronic Obstructive Pulmonary Disease, run by Air Liquide SA at 1 site in Germany.

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 15 inclusion and 10 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 11 Aug 2014. 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 Germany. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Inspiratory Capacity measured by spirometry at rest while breathing each He/O2 mixture compared to its measurement on medical air (time frame: 30 mn). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Aug 2014.
