Clinical Trial Summary

The purpose of this trial is to assess the efficacy, safety and tolerability of remibrutinib (LOU064) 25 milligrams (mg) twice a day (b.i.d.) over placebo for 24 weeks and in comparison to omalizumab 300 mg every 4 weeks (q4w) for 52 weeks in participants with chronic spontaneous urticaria (CSU) inadequately controlled by H1-antihistamines (H1-AH).

Description:

The study consists of three periods, and the total study duration is up to 72 weeks. Approximately 468 adult participants with CSU are expected to be randomized in the study. Screening period: A screening period of up to 4 weeks will allow for the assessment of eligibility, determination of baseline disease activity and wash-out of prohibited medications. Treatment period: The treatment period will be double-dummy and double-blind, with placebo injections matching omalizumab 300 mg s.c. given to participants in the remibrutinib arm and placebo tablets matching remibrutinib 25 mg given to participants in the omalizumab arm (double-dummy). At the randomization visit, eligible participants will be randomized to one of four treatment arms. Follow-up period: There will be a 16-week, treatment-free, safety follow-up period (for participants who do not roll-over to the extension study). All participants will be on a stable, local label-approved standard dose of a second-generation H1-AH ("background therapy") throughout the entire study (starting a minimum of 7 days prior to randomization until the end of the study). In addition, to treat unbearable symptoms of CSU flare-ups, participants will be allowed to use a different second-generation H1-AH on an as-needed basis ("rescue therapy").

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Absolute change from baseline in Weekly Urticaria Activity Score (UAS7)	The UAS7 is the sum of the Weekly Hives Severity Score (HSS7 score) and the Weekly Itch Severity Score (ISS7 score). The possible range of the weekly UAS7 score is 0 - 42 (highest activity).	Week 12
Secondary	Achievement of UAS7=0 (yes/no)	Complete UAS7 response is UAS7 = 0	Week 12
Secondary	Improvement of severity of itch, assessed as absolute change from baseline in ISS7 score	The severity of the itch will be recorded by the participant twice daily in their eDiary, on a scale of 0 (none) to 3 (severe). A weekly score (ISS7) is derived by adding up the average daily scores of the 7 days preceding the visit. The possible range of the weekly score is therefore 0 - 21.	Week 12
Secondary	Improvement of severity of hives, assessed as absolute change from baseline in HSS7 score	The hives (wheals) severity score, defined by number of hives, will be recorded by the participant twice daily in their eDiary, on a scale of 0 (none) to 3 (> 12 hives/12 hours). A weekly score (HSS7) is derived by adding up the average daily scores of the 7 days preceding the visit. The possible range of the weekly score is therefore 0 - 21.	Week 12
Secondary	Occurrence of treatment-emergent adverse events and serious adverse events (SAEs)	To demonstrate the safety and tolerability of remibrutinib (25 mg b.i.d.)	up to 68 weeks
