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.

Conditions

  • Seasonal Allergic Rhinitis

Interventions

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.

DRUG

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.
