This is a US, multi-center, randomized, double-blind, double-dummy, Phase 3b study to evaluate efficacy of remibrutinib (25 mg twice daily \[b.i.d.\] by mouth \[p.o.\]) compared to dupilumab (600 mg loading dose administered subcutaneously (s.c.) followed by 300 mg every 2 weeks s.c.) at early timepoints (4 weeks and earlier), when administered as an add-on treatment to second generation H1-antihistamines (sgH1-AH) (standard label dose as background therapy) in adult US participants with moderate to severe chronic spontaneous urticaria (CSU) inadequately controlled by sgH1-AHs.
Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Novartis AG (NVS) is the sponsoring company for this trial. BiotechSign currently grades this company D (36/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
