What is being measured

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

  1. Safety: Relative Change From Baseline* in Forced Expiratory Volume in 1 s (FEV1) -- 15 Min Post-dose

    Safety: Relative change from baseline* in forced expiratory volume in 1 s (FEV1) at the 15 min post-dose time point. Results are presented as adjusted mean and 95% confidence interval (CI.)

    The potential of the test propellant (HFA-152a vs HFA-134a) for bronchoconstriction was evaluated using centralised spirometry assessments performed during treatment period 1 (TP1) and treatment period 2 (TP2).

    T0 was defined as the moment when the first inhalation took place, and was used to calculate the pre-dose time points.

    T1 was defined as the moment when the last inhalation took place, and was used to calculate the post-dose time points.

    *The baseline FEV1 values were the mean of the two pre-dose assessments (i.e., performed at 45 min and 15 min before T0).

    Measured: At 15 min post-dose after T1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study of Asthma, run by Chiesi Farmaceutici S.p.A. at 1 site in United Kingdom.

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 13 inclusion and 20 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 15 Oct 2024. 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 United Kingdom. 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 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?

Yes. Results are posted in the registry (first posted 15 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety: Relative Change From Baseline* in Forced Expiratory Volume in 1 s (FEV1) -- 15 Min Post-dose (time frame: At 15 min post-dose after T1.). 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 15 Oct 2024.
