What participants receive

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

  • OmalizumabDrug

    Omalizumab was supplied as a sterile, freeze dried preparation, to be reconstituted to deliver 150mg of omalizumab. Each vial was reconstituted with 1.4ml of sterile water for injection. The appropriate dose and dosing frequency of omalizumab were determined by baseline total IgE and body weight. A dosing table was used following the European Summary of Product Characteristics (SmPC) of omalizumab.

  • placeboDrug

    Placebo was a physiological salt solution, administered according to the same administration scheme to respect the same dosing frequency and injected volume.

What is being measured

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

  1. Change (%) From Baseline in FcεRI (High-affinity IgE Receptor) Expression on Blood Basophils and Dendritic Cells After 16 Weeks of Treatment With Omalizumab as Compared With Placebo

    Blood was drawn from participants at baseline and at Week 16. Basophils and dendritic cells expressing FcεRI were counted and the percentage was calculated. Fluorescence was used to label FcεRI so that they could be visualized. The greater the fluorescence intensity the greater FcεRI expression. The change from baseline is described by the difference (%) between the baseline value, before the first study drug administration, and the value observed at the end of study, expressed as a percent of the baseline value.

    Measured: Baseline and Week 16

  2. Change (%) From Baseline in Mean Fluorescence Intensity of FcεRI After 16 Weeks of Treatment With Omalizumab as Compared With Placebo

    Blood was drawn from participants at baseline and at week 16. Basophils and dendritic cells expressing FcεRI were counted and the percentage was calculated. Fluorescence was used to label FcεRI so that they could be visualized. The greater the fluorescence intensity the greater FcεRI expression. The change from baseline is described by the difference (%) between the baseline value, before the first study drug administration, and the value observed at the end of study, expressed as a percent of the baseline value.

    Measured: Baseline and Week 16

Secondary outcomes (11)
  1. Change (%) From Baseline in Percent of Basophils and Dendritic Cells Expressing FcεRI After 4, 8, 12 and 16 Weeks of Treatment

    Blood was drawn from a sub-group of participants at weeks 4, 8, 12, and 16. Basophils and dendritic cells expressing FcεRI were counted and the percentage was calculated. Fluorescence was used to label FcεRI so that they could be visualized. The change from baseline is described by the difference (%) between the baseline value, before the first study drug administration, and the value observed at the specified time point, expressed as a percent of the baseline value.

    Measured: Baseline, Weeks 4, 8, 12 and 16

  2. Change (%) From Baseline in the Mean Fluorescence Intensity of FcεRI After 4, 8, 12 and 16 Weeks of Treatment

    Blood was drawn from a sub-group of participants at weeks 4, 8, 12, and 16. Basophils and dendritic cells expressing FcεRI were counted and the percentage was calculated. Fluorescence was used to label FcεRI so that they could be visualized. The change from baseline is described by the difference (%) between the baseline value, before the first study drug administration, and the value observed at the specified time point, expressed as a percent of the baseline value.

    Measured: Baseline, Weeks 4, 8, 12, and 16

  3. Change From Baseline in the Number of Days With Asthma Symptoms Per Week

    Participants maintained a diary to record the number of days with daytime asthma symptoms per week. This analysis compares the mean number of days per week with asthma symptoms during the 4-week screening period prior to randomization with the mean number of days per wek with asthma symptoms in the last 4 weeks of study treatment (Weeks 12 -16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  4. Change From Baseline in the Number of Puffs of Rescue Medication Per Week

    Participants maintained a diary to record the daytime number of puffs of rescue Short-acting B2 agonist (SABA) used to treat asthma symptoms per week. This analysis compares the mean number of puffs of rescue medication per week during the 4 week screening period prior to randomization to the mean number of puffs per week during the last 4 weeks on study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  5. Change From Baseline in the Number of Nights With Awakenings Per Week

    Participants maintained a diary to record the number of nights with awakenings due to asthma symptoms per week. For this analysis, the mean number of nights with awakenings per week during the 4 week screening period prior to randomization was compared with the mean number of nights with awakenings per week during the last 4 weeks of study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  6. Change From Baseline in the Number of Days With Impairment in Daily Activities Per Week

    Impairment was defined as days with physical activity considered as limited (or "not normal") according to patient's assessment and was recorded in a patient daily diary. For this analysis, the mean number of days with impairment per week during the 4 week screening period prior to randomization was compared with the mean number of days with impairment per week during the last 4 weeks on study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  7. Change From Baseline in the Number of Days With Absence From School or Work Due to Asthma Symptoms

    Participants maintained a diary to record the number of days with absence from school or work due to asthma symptoms. For this analysis, the number of days with absence from school or work in the four weeks prior to randomization (screening period) were compared with the number of absence days during the last 4 weeks on study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  8. Change From Baseline in the Number of Days With Hospitalizations

    Participants maintained a diary to record the number of days with hospitalizations during the study. For this analysis, the number of days with hospitalizations during the screening period (4 weeks prior to randomization) was compared with the number of days with hospitalizations during the last 4 weeks on study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  9. Change From Baseline in the Number of Unscheduled Clinic Visits

    Participants maintained a diary to record the number of unscheduled clinic visits during the study. For this analysis, the number of unscheduled visits during the 4 week screening period prior to randomization is compared with the number of unscheduled visits during the last 4 weeks on treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  10. Change From Baseline in the Morning Daily Peak Expiratory Flow (PEF)

    Peak Expiratory Flow (PEF) was measured every morning using a peak flow meter, and was recorded in the patient diary. For this analysis, the mean morning PEF during the 4-week screening period prior to randomizaton is compared with the mean morning PEF during the last 4 weeks of study treatment (Weeks 12 - 16).

    Measured: Baseline (the 4 week screening period prior to randomization) and End of Study (Weeks 12 - 16)

  11. Physician's Overall Assessment of Treatment Effectiveness

    The Physician's overall assessment of treatment effectiveness was graded 1-5 as 1 = Excellent asthma control (complete control) 2 = Good asthma control (marked improvement) 3 = Moderate asthma control (discernible, but limited improvement) 4 = Poor asthma control (no appreciable change) 5 = Very poor asthma control (worsening)

    Measured: After 16 weeks of treatment

Who may be eligible to take part?

The sponsor lists 8 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 8 Aug 2011. 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?

Yes. Results are posted in the registry (first posted 1 Aug 2011). 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 FcεRI (High-affinity IgE Receptor) Expression on Blood Basophils and Dendritic Cells After 16 Weeks of Treatment With Omalizumab as Compared With Placebo (time frame: Baseline and Week 16). 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 NCT00454051, 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.
