What is being measured

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

  1. Change From Baseline in Eosinophils Cells Count in the Bronchial Submucosa at Week 12

    Inflammatory cells i.e. eosinophils were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.

    Measured: Baseline, Week 12

  2. Change From Baseline in Mucin-Stained Area in the Bronchial Submucosa at Week 12

    Mucin was identified by staining with Alcian-blue periodic acid-Schiff and/or immunostaining for MUC5AC and then the mucin-positive area was measured and expressed per square millimeter.

    Measured: Baseline, Week 12

  3. Change From Baseline in Mast Cells Count (Chymase Positive) in the Bronchial Submucosa at Week 12

    Inflammatory cells i.e. mast cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.

    Measured: Baseline, Week 12

  4. Change From Baseline in Mast Cells Count (Tryptase Positive) in the Bronchial Submucosa at Week 12

    Inflammatory cells i.e. mast cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.

    Measured: Baseline, Week 12

  5. Change From Baseline in T-Lymphocytes Count in the Bronchial Submucosa at Week 12

    T-Lymphocytes i.e. CD3 positive cells were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.

    Measured: Baseline, Week 12

  6. Change From Baseline in T-Helper Lymphocytes Count in the Bronchial Submucosa at Week 12

    T-helper i.e. CD4 positive lymphocytes were counted in the bronchial submucosa of biopsy thin sections using quantitative immunohistochemistry and reported as the number of cells per square millimeter.

    Measured: Baseline, Week 12

Secondary outcomes (5)
  1. Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) at Week 12

    FeNO is a surrogate marker for airway inflammation. FeNO was analyzed using a NIOX instrument or similar analyzer using a flow rate of 50 mL/second, and reported in ppb.

    Measured: Baseline, Week 12

  2. Average Change in Fractional Exhaled Nitric Oxide (FeNO) From Baseline to Week 6 Through Week 12

    FeNO is a surrogate marker for airway inflammation. FeNO was analyzed using a NIOX instrument or similar analyzer using a flow rate of 50 mL/s, and reported in ppb.

    The average change in FeNO from baseline to Week 6 through Week 12 was calculated as follows: For each participant the change in FeNO from Baseline to Week 6, Week 8, Week 10 and Week 12 was calculated (value at Week X - value at baseline). Subsequently the weekly mean of these 4 "change from baseline" values was determined (Weeks 6, 8, 10 and 12). Using these weekly mean values the overall arithmetic mean and standard deviation of the average change in FeNO from baseline to Week 6 through Week 12 was calculated.

    Measured: From Baseline to Week 6 through Week 12

  3. Number of Participants With Antidrug Antibodies (ADA)

    Anti-drug antibodies were detected using a validated immunoassay. Incidence of ADA were classified as following: 1) Pre-existing immunoreactivity - an ADA positive response in the assay at baseline with all post treatment ADA results negative or an ADA positive response at baseline with all post treatment ADA responses less than 4-fold over baseline titer levels. 2) Treatment-emergent ADA: an ADA positive response in the assay post first dose, when baseline results were negative or missing. 3) Treatment-boosted ADA: an ADA positive response in the assay post first dose that was greater-than or equal to 4-fold over baseline titer levels, when baseline results were positive.

    Measured: From Baseline up to 24 weeks

  4. Pharmacokinetics (PK) Assessment: Serum Functional Dupilumab Concentration

    Serum functional dupilumab concentrations were determined using an enzyme-linked immunosorbent assay (ELISA) method.

    Measured: Week 0, Week 2, 6, 8, 12, 18, End of study (Week 24)

  5. Number of Participants With Treatment Emergent Adverse Events (TEAEs)

    Adverse event (AE) was defined as any untoward medical occurrence in a participant who received investigational medicinal product (IMP) without regard to possibility of causal relationship with this treatment. TEAEs: AEs that developed or worsened or became serious during between the first administration of study medication to the end of the 12 week Post-treatment Period. Serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. Any TEAE included both serious and non-serious AEs.

    Measured: Baseline up to Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Dupilumab SAR231893/REGN668, fluticasone propionate and salmeterol and budesonide and formoterol in people with Asthma, run by Sanofi 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 12 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 4 Apr 2022. 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 United States, Germany, Canada, Denmark, United Kingdom 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. 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 28 Jan 2019). 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?

Change From Baseline in Eosinophils Cells Count in the Bronchial Submucosa at Week 12 (time frame: Baseline, Week 12). The study lists 6 primary outcomes in all. 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 4 Apr 2022.
