A Phase 2b/3 Multi-Center, Randomized, Double-Blind, Multi-Dose, Placebo-Controlled, Parallel-Group Set of Studies to Evaluate the Efficacy and Safety of Induction and Maintenance Therapy With TD-1473 in Subjects With Moderately-to-Severely Active Ulcerative Colitis
A Phase 2b/3 Multi-Center, Randomized, Double-Blind, Multi-Dose, Placebo-Controlled, Parallel-Group Set of Studies to Evaluate the Efficacy and Safety of Induction and Maintenance Therapy With TD-1473 in Subjects With Moderately-to-Severely Active Ulcerative Colitis
A Phase 2b/3 set of studies to evaluate the efficacy and safety of induction and maintenance therapy with TD-1473 in subjects with moderately-to-severely active ulcerative colitis with up to 60 weeks of treatment.
This protocol consists of 3 separate studies: an 8-week Phase 2b dose-finding induction study, an 8-week dose-confirming Phase 3 induction study, and a 44-week Phase 3 maintenance study. Subjects who respond to induction will enter the maintenance study; those who do not will receive TD-1473 during extended induction. The safety and efficacy data of the Phase 2b study will be analyzed to select the induction and maintenance dose regimens for the confirmatory Phase 3 studies. Participants who have disease relapse or complete the maintenance study may be eligible to enter a separate long-term safety study. Efficacy, pharmacokinetic, biomarkers, and safety will be evaluated in all 3 studies.
240 subjects are planned for the Phase 2b and the planned Primary Completion Date for this portion of the study is JULY 2021. 640 subjects are planned for the Phase 3 portion of the study.
