Panelists discuss how newer Bruton tyrosine kinase (BTK) inhibitors being developed for chronic spontaneous urticaria (CSU), particularly remibrutinib (in phase 3 trials) and rilzabrutinib (in phase 2), are designed to be more selective than earlier oncology-focused BTK inhibitors, potentially reducing off-target effects like bleeding, cardiovascular complications, and GI issues.

Panelists discuss how chronic spontaneous urticaria develops through 2 distinct pathways: autoallergic CSU involving IgE-mediated mast cell activation (type I hypersensitivity) and autoimmune CSU where IgG autoantibodies target FcεRI receptors or IgE itself (type IIb hypersensitivity), both ultimately leading to mast cell degranulation and wheal formation.
