A reaction history was documented for 95% and all challenged foods had a positive allergen-specific IgE (median 34 [IQR: 12, >100] kUA/L). OFCs were performed at a median of 7 months (range: 4-14) after starting omalizumab. Among OFCs to any food with a goal dose ≥6000 mg (n=56), 89% successfully consumed ≥1000 mg, 86% ≥2000 mg, 75% ≥4000 mg, and 66% ≥6000 mg. Allergic reactions occurred in 45% (n=33) of all OFCs with 21 treated with antihistamines and 2 treated with epinephrine. Dietary introduction of allergenic foods was permitted following 92% of OFCs. Omalizumab treatment response was associated with higher baseline total IgE, q2 versus q4 week dosing, higher total omalizumab dose per 4-weeks per weight, and lower allergen-specific IgE to total IgE ratio.CONCLUSION: Omalizumab can be effectively used for the treatment of FA in the clinical setting and may enable the introduction of allergenic foods into the diet for most patients.PMID:41802568 | DOI:10.1016/j.jaip.2026.02.033
