Efficacy/ Safety of Omalizumab in Patients With Seasonal Allergic Asthma and Seasonal Allergic Rhinoconjunctivitis

Study Overview
=================
Brief Summary
-----------------
Efficacy/ safety for the combination of anti-IgE (Omalizumab) and specific immunotherapy (Depigoid) in patients with not adequately controlled seasonal allergic asthma and comorbid seasonal allergic rhinoconjunctivitis.

Detailed Description
-----------------
This was an open-label extension period of the previously randomized, multicenter, double-blind, placebo-controlled, parallel-group trial to demonstrate the benefit of pre- and co-seasonal combination therapy with anti-IgE (omalizumab) and specific immunotherapy (Depigoid) in patients with seasonal allergic asthma and co-morbid seasonal allergic rhinoconjunctivitis. During the open-label period, all patients received Depigoid monotherapy for two follow-up seasons every 4 weeks, 26 injections in total. The extension period was performed to evaluate the influence of omalizumab on the follow-up treatment with Depigoid in seasonal asthma. This study was a follow-up to the core IGE025ADE03 study, in which patients received omalizumab treatment. In this follow-up study, no patient received omalizumab.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Daily Symptom Load | The daily symptom load (low=0, high=unbounded) represents the daily combined asthma and rhinoconjunctivitis symptom severity scores plus the daily asthma rescue medication score based on patient diary entries. A higher score indicates a worse patient asthma condition. Symptoms (e.g. - difficulty breathing, cough, tightness of chest, sneezing, itchy nose, red eyes, etc.) were evaluated daily by the patient using a 4-point scale (0=no symptom, 1=mild, 2=moderate, 3=severe). Point values were assigned by specific rescue medication usage. The daily scores were averaged over pollen days by site. | Recorded daily during the 2007 and 2008 pollen season | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Asthma/Rhinoconjunctivitis Symptom Severity Score | The symptom severity score was defined as the mean of the daily symptom severity scores (asthma symptoms during the day, asthma symptoms at night, rhinitis symptoms, and conjunctivitis symptoms) during the pollen season. The daily symptom severity scores were evaluated daily by the patient using a 4-point scale (0 = none (no symptom), 1 = mild, 2 = moderate, 3 = severe) and were recorded in a patient diary. The possible minimum value for the Asthma/Rhinoconjunctivitis Symptom Severity Score is 0, and the possible maximum value is 3. Higher values represent a worse outcome. | Recorded daily during the 2007 and 2008 pollen season | 
| Asthma/Rhinoconjunctivitis Rescue Medication Score | Asthma/Rhinoconjunctivitis rescue medication score is a component of symptom load. Patients were advised that between visits they could take short acting β-2 agonist rescue medication as initial rescue medication for symptoms of intercurrent bronchospasm. Patients were advised that between visits they could take rescue medication (systemic antihistamines) on an as-needed basis for symptoms of grass pollen allergic rhinoconjunctivitis. The symptom load and all its components were based on the patient's entries in their diaries. | Recorded daily during the 2007 and 2008 pollen season | 
| Percentage of Participants by Global Evaluation of Treatment Effectiveness (GETE) Assessment Category Performed by the Investigator | The investigator's assessment of the global evaluation of treatment effectiveness (GETE) using a five point scale, which evaluates change in asthma control/symptoms. GETE is scored as 1='excellent', 2='good', 3='moderate', 4='poor', 5='worsening' and (.)='missing'). | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Percentage of Participants by Global Evaluation of Treatment Effectiveness (GETE) Assessment Category Performed by the Patient | The patient's assessment of the global evaluation of treatment effectiveness (GETE) using a five point scale, which evaluates change in asthma control/symptoms. GETE is scored as 1='excellent', 2='good', 3='moderate', 4='poor', 5='worsening' and (.)='missing'). | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Asthma Control Questionnaire (ACQ) | The Asthma Control Questionnaire (ACQ) was developed and validated for assessing asthma symptom control in patients in clinical trials as well as for individuals in clinical practice. It is a simple questionnaire consisting of seven questions assessing symptoms, airway caliber and rescue β2-agonist use. It uses a 7-point scale. The possible minimum value is 1, the possible maximum value is 7. Higher values represent worse asthma control and quality of life, respectively. | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Asthma Quality of Life Questionnaire (AQLQ) | The Asthma Quality of Life Questionnaire (AQLQ) is a 32-item disease specific questionnaire designed to measure functional impairments that are most important to patients with asthma. It consists of 4 domains (symptoms, emotions, exposure to environmental stimuli and activity limitation). Patients are asked to recall their experiences during the previous 2 weeks and to score each item on a 7-point scale. The overall AQLQ score is the mean response to all 32 questions (low=1, high=7). Higher values represent better quality of life. | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) | The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) is a 28-item disease specific questionnaire designed to measure functional impairments that are most important to patients with rhinoconjunctivitis. It consists of 7 domains (activities, sleep, common complaints, practical problems, nasal symptoms, ocular symptoms, and emotions). Patients recall their experiences during the previous week and to score each item on a 7-point scale. The overall RQLQ score is the mean response to all 28 questions (low=1, high=7). Higher values represent worse quality of life. | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Asthma Quality of Life Questionnaire (AQLQ) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) - Clinical Differences to Baseline | Both the AQLQ and RQLQ clinical differences were categorized as important, moderate, or meaningful improvement; no clinical change; meaningful, moderate, or important impairment. Clinically important differences in scores between any two assessments have been determined by the authors of the AQLQ and RQLQ. Changes in scores of 0.5 to 1.0 are considered clinically meaningful; 1.0 to 1.5 as moderate and > 1.5 as marked clinically important differences for any individual domain or for the overall summary score. | Baseline of core study and 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Work Productivity and Activity Impairment | The Work Productivity and Activity Impairment questionnaire measures time missed from work, impairment of work and regular activities. It consists of 6 items. The outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity. The minimum value is 0 (0 %), the maximum value is 1 (100%). The recall time is 1 week. For this study WPAI-AA was used defining the specific health problem as allergic asthma, which has been validated by the instrument owner. | 52 Weeks (2007) and 104 Weeks (2008) after completion of core study | 
| Lung Function as Assessed by Forced Expiratory Volume in One Second (FEV1) | The spirometric parameter Forced Expiratory Volume in One Second (FEV1) was measured during grass pollen season before each injection of Depigoid. | Assist during 2007 and 2008 pollen season | 
| Lung Function as Assessed by Peak Expiratory Flow (PEF) | The spirometric parameter Peak Expiratory Flow (PEF) was measured during grass pollen season before each injection of Depigoid. PEF was collected in the patient diary at seven days after visit 22, 23 and 24 as well as 35, 36 and 37. For analyzing purposes these data were averaged after the respective visits. Missing PEF-values from the patient diary were not replaced. | Assist during 2007 and 2008 pollen season |
