What is being measured

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

  1. Proportion of the Participants Who Discontinued OCS Without Loss of Asthma Control at Week 28 and Week 52

    The proportion (expressed as a percentage) of participants who discontinued OCS without loss of asthma control is presented.

    Loss of asthma control was defined as asthma worsening or exacerbation. Asthma worsening was defined by an increase of Asthma Control Questionnaire 6 (ACQ-6) score ≥0.5 from baseline. Asthma exacerbation was defined by worsening of asthma symptoms that led to temporary bolus/burst of systemic corticosteroids (SCS; or a temporary increase in stable OCS background dose) for at least 3 consecutive days (a single depo-injectable dose of corticosteroids being considered equivalent to a 3-day bolus/burst of SCS), and/or an emergency room (ER) or urgent care visit requiring SCS, and/or inpatient hospitalisation, both due to asthma.

    Measured: Week 28 and Week 52

  2. Proportion of the Participants Who Reduced Daily Prescribed Maintenance OCS Dose to ≤5 mg/Day Without Loss of Asthma Control at Week 28 and Week 52

    The proportion (expressed as a percentage) of the participants who reduced daily prescribed maintenance OCS dose to ≤5 mg/day without loss of asthma control at Week 28 and Week 52 is presented.

    Measured: Week 28 and Week 52

Secondary outcomes (14)
  1. Annual Asthma Exacerbation Rate (AAER) Over Week 28 and Over Week 52

    The AAER over Week 28 and over Week 52 is presented. The AAER was calculated as the total number of asthma exacerbations over the period (Week 28/52) divided by the total time at risk for the period (Week 28 or Week 52).

    Measured: Week 28 and Week 52

  2. Rate of Asthma Exacerbation Associated With Hospitalisation or ER Visit Over 28 Weeks and Over 52 Weeks

    The AAER for exacerbations associated with hospitalisation or ER visit over 28 weeks and over 52 weeks is presented. The AAER was calculated as the total number of asthma exacerbations over the period (Week 28/52) divided by the total time at risk for the period (Week 28 or Week 52).

    Measured: Week 28 and Week 52

  3. Rate of Asthma Exacerbation Associated With Hospitalisation Over 28 Weeks and Over 52 Weeks

    The AAER for exacerbations associated with hospitalisation over 28 weeks and over 52 weeks are presented. The AAER was calculated as the total number of asthma exacerbations over the period (Week 28/52) divided by the total time at risk for the period (Week 28 or Week 52).

    Measured: Week 28 and Week 52

  4. Proportion of the Participants Who Did Not Experience an Exacerbation Over 28 Weeks and Over 52 Weeks

    The proportion (expressed as a percentage) of participants who completed 28 or 52 weeks of treatment and did not experience an exacerbation over 28 weeks and over 52 weeks is presented.

    Measured: Week 28 and Week 52

  5. Proportion of the Participants Who Did Not Experience an Exacerbation Associated With Hospitalisation or ER Visit Over 28 Weeks and Over 52 Weeks

    The proportion (expressed as a percentage) of participants who completed 28 or 52 weeks of treatment and did not experience an exacerbation associated with hospitalisation or ER visit over 28 weeks and over 52 weeks is presented.

    Measured: Week 28 and Week 52

  6. Proportion of the Participants Who Did Not Experience an Exacerbation Associated With Hospitalisation Over 28 Weeks and Over 52 Weeks

    The proportion (expressed as a percentage) of participants who completed 28 or 52 weeks of treatment and did not experience an exacerbation associated with hospitalisation over 28 weeks and over 52 weeks is presented.

    Measured: Week 28 and Week 52

  7. Proportion of the Participants With ≥50% Reduction From Baseline in Daily Maintenance OCS Dose at Week 28 and Week 52

    The proportion (expressed as a percentage) of participants with ≥50% reduction from baseline in daily maintenance OCS dose at Week 28 and Week 52 is presented.

    The baseline OCS dose is the prescribed OCS dose prior to first dose of investigational product (IP). The final daily OCS dose was defined as the last dose reported by participants with asthma stability verified (no change in OCS dose for at least 2 consecutive weeks).

    Measured: Week 28 and Week 52

  8. Categorised Percent Reduction From Baseline in the Daily Maintenance OCS Dose at Week 28 and Week 52

    The categorised percent reduction from baseline in the daily maintenance OCS dose (categories: ≥90% to ≤100% reduction, ≥75% to <90% reduction, ≥50% to <75% reduction, >0% to <50% reduction, no change or any increase) at Week 28 and Week 52 is presented.

    The baseline OCS dose is the prescribed OCS dose prior to first dose of IP. The final daily OCS dose was defined as the last dose reported by participants with asthma stability verified (no change in OCS dose for at least 2 consecutive weeks).

    Measured: Week 28 and Week 52

  9. Absolute Change From Baseline in Daily Maintenance OCS Dose at Week 28 and Week 52

    The absolute change from baseline in daily maintenance OCS dose at Week 28 and Week 52 is presented.

    The baseline OCS dose is the prescribed OCS dose prior to first dose of IP. The final daily OCS dose was defined as the last dose reported by participants with asthma stability verified (no change in OCS dose for at least 2 consecutive weeks).

    Measured: Week 28 and Week 52

  10. Percent Change From Baseline in Daily Maintenance OCS Dose at Week 28 and Week 52

    The percent change from baseline in daily maintenance OCS dose at Week 28 and Week 52 is presented.

    The baseline OCS dose is the prescribed OCS dose prior to first dose of IP. The final daily OCS dose was defined as the last dose reported by participants with asthma stability verified (no change in OCS dose for at least 2 consecutive weeks).

    Measured: Week 28 and Week 52

  11. Change From Baseline in Post-bronchodilator FEV1 at Week 28 and Week 52

    The change from baseline in post-bronchodilator FEV1 at Week 28 and Week 52 is presented. Baseline was defined as the last measurement at or prior first dose of IP.

    FEV1 = forced expiratory volume in 1 second

    Measured: Week 28 and Week 52

  12. Change From Baseline in ACQ-6 at Week 28 and Week 52

    The Asthma Control Questionnaire 6 (ACQ-6) is a 6-item questionnaire which includes the following questions: 1) Awakening at night by symptoms, 2) Limitations of normal daily activities, 3) Waking in the morning with symptoms, 4) Dyspnoea, 5) Wheeze, and 6) Daily rescue medication. Questions were scored from 0 (totally controlled) to 6 (severely uncontrolled) and the ACQ-6 score was computed as the unweighted mean of the responses to the 6 questions. Higher scores indicate poorer outcomes.

    The change from baseline in ACQ-6 at Week 28 and Week 52 is presented.

    Measured: Week 28 and Week 52

  13. Change From Baseline in Standardised AQLQ(s)+12 Total Score at Week 28 and Week 52

    The Asthma Quality of Life Questionnaire for 12 Years and Older (AQLQ[S]+12) is a questionnaire that measures the health-related quality of life experienced by asthma participants. Questions were scored from 7 (no impairment) to 1 (severe impairment). The overall score is calculated as the mean response to all questions. Higher scores indicate better outcomes.

    The change from baseline in standardised AQLQ(S)+12 total score at Week 28 and Week 52 is presented.

    Measured: Week 28 and Week 52

  14. Change From Baseline in SGRQ Total Score at Week 28 and Week 52

    The St. George's Respiratory Questionnaire (SGRQ) is a 50-item instrument developed to measure the health status of participants with airway obstruction diseases. The total score indicates the impact of disease on overall health status. The total score ranges for the SGRQ are 0-100, with higher scores indicating worse health status.

    The change from baseline in SGRQ total score at Week 28 and Week 52 is presented.

    Measured: Week 28 and Week 52

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

Who may be eligible to take part?

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 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 77 sites in Argentina, Poland, France, United States, Latvia and 6 more countries. 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?

Yes. Results are posted in the registry (first posted 11 Dec 2025). 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?

Proportion of the Participants Who Discontinued OCS Without Loss of Asthma Control at Week 28 and Week 52 (time frame: Week 28 and Week 52). The study lists 2 primary outcomes in all. 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 NCT05274815, 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 11 Dec 2025; AzTrials last refreshed its copy on 7 Nov 2026.
