About this trial
This is a Phase 2, multinational, multicenter, randomized, double-blind, placebo-controlled, dose ranging study to evaluate the efficacy and safety of SAR441566 in adults with moderate-to-severe UC. The primary objective of this study is to assess efficacy of different doses of SAR441566 on clinical remission in participants with moderate-to-severe ulcerative colitis.
This study will include a screening period of up to 28 days (+ 7 calendar days if needed) followed by the main study treatment period of 52 weeks which will be comprised of a double blind (DB) treatment period with 12 weeks of induction period followed by a maintenance period of 40 weeks and 2-week follow-up after end of treatment.
Additionally, an Open Label (OL) period of up to 40 weeks will be offered to eligible participants (for participants not enrolling in the LTS study).
* The study duration will be up to 59 weeks. * The treatment duration will be up to 52 weeks in the DB arm and up to 40 weeks in the OL arm. * The number of visits will be 12 for the main study treatment period and 8 for the OL treatment period.
