|---|---|
| Omalizumab Eligible participants received a maximum dose of 600 mg omalizumab via subcutaneous injection for 6 months in the double-blind phase of the study. The study medication was to be administered at the same time of day. Study medication was injected subcutaneously into the upper arm in the area of the deltoid or to the thigh. A maximum 600 mg dose required 4 injections. All participants who entered the study received itraconazole twice daily, while receiving oral corticosteroids, with a maximum daily dose of 400 mg.
Patients completed double-blinded phase, entered open-label treatment period of 6 months and continued the same regimen of omalizumab of double-blinded phase. | 9 |
| Placebo Eligible participants received placebo comparator via subcutaneous injection for 6 months in the double-blind phase of the study. The study medication was to be administered at the same time of day. Study medication was injected subcutaneously into the upper arm in the area of the deltoid or to the thigh. All participants who entered the study received itraconazole twice daily, while on oral corticosteroids, with a maximum daily dose of 400 mg. | 5 |
