• Status: Not yet recruiting
• Trial end date: 2024-01-08

Summary

The first phase of this study will be a parallel, 12-week treatment, Phase 2, double-blind, 4 arm study to assess the safety and effectiveness of 3 oral doses of SAR444671 (rilzabrutinib), i.e. dose A, B and C, compared with placebo for decreasing the frequency and severity of itch and urticaria in male and female participants aged 18 years inclusive or older with CSU.

After completion of the double-blind phase of the study, participants will be given the option of enrolling in the 40-week open label extension (OLE) phase of the study. Participants will receive open-label rilzabrutinib at dose C (the dose may be modified based on the 12-week safety and efficacy data). Due to the fact that some participants may be receiving rilzabrutinib for the first time, all participants will be monitored at Week 16, Week 20, and Week 24. Afterwards, participants will be monitored at Week 36 and Week 52.
