Official title: A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of ST-0529 in Subjects With Moderately to Severely Active Ulcerative Colitis

Status Terminated

Clinical Trial Summary

Study CYC-202 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of ST-0529 in subjects with moderately to severely active UC, defined as a score of 5 to 9 on the 3-Component Adapted Mayo Score (comprised of rectal bleeding, stool frequency and endoscopy sub-scores; score range 0-9).

Clinical Trial Description

The study consists of a Screening period, Treatment period and Follow-up. The Screening period is comprised of two separate in-clinic visits, SV1 and SV2. At the initial Screening visit (SV1), subjects will be required to provide written informed consent to participate in the study and will then be assessed for eligibility. Electronic diaries will be provided to subjects at this visit to use for the duration of the study in order to record information relating to their UC disease. Subjects will return to the clinic for their Screening endoscopic assessment (SV2). Ulcerative colitis disease activity for eligibility will be assessed using the 3-Component Adapted Mayo Score. Upon successful completion of the Screening period, subjects will return to the clinic for their Baseline visit.

During the Treatment period, subjects will be evaluated in the clinic at Baseline (Day 1), Week 2, Week 4, Week 8, and Week 12 (End of Treatment Period). At Week 6 and Week 10, subjects will be contacted by telephone to assess Adverse Events (AEs), concomitant medication usage and study drug regimen adherence.

Subjects who complete the 12-week Treatment period will attend the Week 16 End of Study (EOS) visit. Subjects who discontinue study drug and withdraw or are withdrawn from the study before the Week 12 visit will be requested to return to the clinic as soon as possible to complete an Early Termination (ET) visit. ;
