July 18, 2012 updated by: Novartis Pharmaceuticals

A 16-week Treatment, Multicenter, Randomized, Double Blind, Placebo-controlled, Parallel-group Study to Assess the Effect of Omalizumab on the Expression of FcεRI Receptors of Blood Basophils and Dendritic Cells in Patients With Severe Persistent Non-atopic Asthma, Uncontrolled Despite Optimal Therapy

This study will assess the change in the expression of FcεRI receptors of blood basophils and dendritic cells after 16 weeks of treatment with omalizumab as compared with placebo, in adult patients with non-atopic severe persistent asthma, uncontrolled despite optimal therapy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

Severe persistent asthma with the following characteristics:

  • Treated with high-dose inhaled corticosteroid (i.e. > 1,000 µg beclometasone dipropionate equivalent per day) plus inhaled long-acting β2 agonist (with or without maintenance oral corticosteroid).
  • Non-atopic, i.e. negative blood multiallergic testing and negative Aspergillus-specific IgE-radio allergosorbent blood test and negative skin prick tests to a battery of common aeroallergens

Exclusion Criteria:

  • Current smokers or smoking history stopped for less than 3 years or > 10 pack years.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Omalizumab
Participants received subcutaneous injections of omalizumab every 2 weeks or every 4 weeks; dosage dependent on IgE level and body weight.
Drug: omalizumab
Omalizumab was supplied in 5mL vials with solution for subcutaneous injection.
Placebo Comparator: Placebo
Participants received subcutaneous injections of placebo to omalizumab every 2 weeks or every 4 weeks.
Drug: Placebo
Placebo was supplied in vials with solution for subcutaneous injection.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in the Expression of FcεRI Receptors of Blood Basophils
Time Frame: Baseline and 16 weeks
Venous blood samples were collected at screening and at Week 16. Flow cytometry analysis determined the FcεRI receptors expression of blood basophils (mean fluorescence intensity(MFI)). Relative change in mean fluorescence intensity at the end of study was expressed as a percentage of baseline value.
Baseline and 16 weeks
Change From Baseline in the Expression of FcεRI Receptors of Dendritic Cells
Time Frame: Baseline and 16 weeks
Venous blood samples were collected at screening and at Week 16. Flow cytometry analysis determined the FcεRI receptors expression of dendritic cells (mean fluorescence intensity (MFI)). Relative change in mean fluorescence intensity at the end of study was expressed as a percentage of baseline value.
Baseline and 16 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Fractional Exhaled Nitric Oxide (FeNO)
Time Frame: Baseline and 4, 8, 12 and 16 weeks
FeNO was measured at baseline, and after 4, 8, 12 and 16 weeks of treatment. Absolute change in FeNO was expressed at each time point versus baseline value.
Baseline and 4, 8, 12 and 16 weeks
Change From Baseline in Induced Sputum Eosinophil Count
Time Frame: Baseline and 16 weeks
The induced sputum eosinophil count was measured in a subset of patients in selected centers. Sputum samples were collected at screening and Week 16. Sputum eosinophil count was expressed as a percentage of total nonsquamous cells. Absolute change in sputum eosinophil count was expressed versus baseline value.
Baseline and 16 weeks
Change From Baseline in Score of the Shortened Version of the Asthma Control Questionnaire (Symptoms Plus Short-acting β2-agonist)
Time Frame: Baseline and 16 weeks
The shortened version of the asthma control questionnaire (symptoms plus β2-agonist) consists of 6 subscores (nighttime waking, symptoms on waking, activity limitation, shortness of breath, wheeze and rescue short-acting β2-agonist use) between 0 and 6 (0 = no impairment; 6 = maximum impairment) and a total score between 0 and 6 (subscores mean value). Absolute change in total score and subscores count was expressed versus baseline value. A decrease in score indicates improvement.
Baseline and 16 weeks
Change From Baseline in Nasal Symptom Global Score and Individual Components
Time Frame: Baseline and 16 weeks
Nasal symptom score calculated from six scales assessing the nasal symptom severity (sneezing, runny nose, congestion, itchy nose, postnasal drip and nasal symptoms overall). These six scores were rated on a scale from 1 to 7, with 7 being the worst rating. Absolute changes in these six scores were expressed versus baseline values. A negative change indicates improvement. The range of the global score was from 1 to 7, since this is the mean value of all the subscores.
Baseline and 16 weeks
Physician and Patient Global Evaluation of Treatment Effectiveness
Time Frame: 16 weeks
The GETE is an assessment of asthma symptoms controlled in response to asthma treatment. The evaluation was performed independently by both investigator and patient using the same 5 point scale. The scale points are: excellent, good, moderate, poor and worsening. A good or excellent response is suggested as a means of defining a patient who has responded to treatment.
16 weeks
Change in Forced Expiratory Volume in 1 Second (FEV1) From Baseline to 16 Weeks
Time Frame: Baseline and 16 weeks
Spirometry was conducted according to internationally accepted standards. At least three maneuvers were performed at each sampling timepoint. The FEV1 recorded was taken from the maneuver obtained from the single best test curve. The best test curve was defined as the spirogram that gave the largest FEV1.
Baseline and 16 weeks
Number of Patients With at Least One Asthma-related Event Over 16 Weeks
Time Frame: 16 weeks
Asthma-related events were: unscheduled medical visits, emergency room visits and hospitalizations. Details of exacerbations requiring oral or IV corticosteroids were recorded at each visit.
16 weeks

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
