Clinical Trial Summary

The purpose of this study was to demonstrate the efficacy and safety of omalizumab compared with placebo, on top of SoC (anti-histamine and nasal corticosteroid) in adult and adolescent patients with severe Japanese cedar pollinosis, whose symptoms were inadequately controlled despite the current recommended therapies (nasal corticosteroids plus one or more medications out of anti-histamine, leukotriene receptor antagonist, or prostaglandin D2/thromboxane A2 receptor antagonist) in the previous 2 Japanese cedar pollen seasons.

• With a severe asthma treated with high dose inhaled corticosteroid (= 800 µg/day fluticasone propionate or an equivalent for aged = 16 to <75 years, > 200 µg/day for aged = 12 to <16 years).

Intervention

Drug:
• Omalizumab
Omalizumab were administered by subcutaneous injection. Dose (75 to 600 mg) and dosing frequency (every 2 or 4 weeks) were determined by serum total IgE level (IU/mL) and body weight (kg) measured at the screening epoch according the dosing table.
• Placebo
Placebo were administered by subcutaneous injection. Dose (75 to 600 mg) and dosing frequency (every 2 or 4 weeks) were determined by serum total IgE level (IU/mL) and body weight (kg) measured at the screening epoch according the dosing table.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Nasal Symptom Score	Nasal symptoms (sneezing, rhinorrhea and nasal congestion) were recorded by the patient everyday in their e-Diary, on a scale of 0 (none) to 4 (intense/severe). Nasal symptom score (0-12 point) consisted of score for severity of sneezing (0-4 point), rhinorrhea (0-4 point) and nasal congestion (0-4 point).; Severe symptom period: The three weeks where the cumulative value of the mean daily nasal symptom score is the maximum. The three weeks must also meet one of the following criteria: 2) = 70% of the period with concomitant use of fluticasone propionate is included in this three weeks. 2) = 70% of this three weeks includes the period with concomitant use of fluticasone propionate. If not, severe symptom period was extended at a minimum to meet one of the criteria above. The severe symptom period will be defined as: the three weeks where the cumulative value of the mean daily nasal symptom score will be the maximum.	Severe symptom period (from 23Feb2018 to 24March2018)
Secondary	Mean Ocular Symptom Score and Mean Nasal Ocular Symptom Score	Ocular symptoms (itchy and watery eye) were recorded by the patient everyday in their e-Diary, on a scale of 0 (none) to 4 (intense/severe). Ocular symptom score (0-8 point) consisted of score for severity of itchy eye (0-4 point) and watery eye (0-4 point).; Nasal ocular symptom score consisted of nasal symptom score and ocular symptom score.; Nasal ocular symptom score is the sum of nasal symptom score (0-12) and ocular symptom score (0-8) 0 presents no nasal ocular symptom and 20 presents worse outcome.
