Two studies examined blood biomarkers for omalizumab response in chronic spontaneous urticaria. Basophil histamine content did not predict response, while higher baseline monocyte counts were linked to complete remission in a 52-patient retrospective analysis.
Novartis received EU approval for Rhapsido (remibrutinib) as the first oral targeted treatment for chronic spontaneous urticaria. Phase 3 data also showed significant efficacy in chronic inducible urticaria, with filings underway for additional indications.
A study in the Journal of Experimental Medicine found that DOCK8 deficiency drives severe food allergies by expanding Tfh13 cells and reducing regulatory T-cells. The findings help explain why DOCK8 mutations, but not STAT3 mutations alone, consistently lead to elevated food-specific IgE and clinically significant reactions.
