An Investigation of Oral BT051 in Subjects With Moderately to Severely Active Ulcerative Colitis (UC) — SCOUT  

Ulcerative Colitis Clinical Trial

Official title: A Multicenter, Randomized, Placebo-Controlled, Multiple-Ascending-Dose Investigation of the Oral Anti-Inflammatory Agent BT051 in Subjects With Moderately to Severely Active Ulcerative Colitis (UC)

Status Completed

Clinical Trial Summary

This is a randomised, double-blind, placebo-controlled study to assess the safety and tolerability of multiple ascending doses of BT051 in subjects with moderately to severely active ulcerative colitis. Subjects will be randomised using a 3 active:1 placebo ratio to 3 ascending dose cohorts of 8 subjects and will be dosed daily for 28 days. The 3 initial dose levels will be 200 mg, 800 mg and 3200 mg per day. Progression to the next cohort will be based on the safety and tolerability of the previous cohort.

Clinical Trial Description

This is a randomized, placebo-controlled, multiple-ascending-dose (MAD) study enrolling subjects with moderately to severely active UC. Subjects with prior exposure to biologic or JAK inhibitors will be limited to 30% of the total subject population; those who have failed 2 or more biologic therapies (i.e., biologic and JAK inhibitor, 2 biologics in the same class, or 2 biologics from different classes) will be limited to 20% of the total subject population. Subjects will be randomized to one of 3 doses of oral BT051 (200 mg, 800 mg, or 3200 mg) or placebo, in ascending dose groups based on the safety and tolerability of the previous cohort. Safety and tolerability will be assessed by a Safety Review Committee (SRC) after all subjects in each cohort have completed at least 14 days of treatment, before proceeding to the next higher dose cohort. The SRC may recommend that the next cohort proceed with a higher dose as planned, or the SRC may recommend additional subjects be dosed at the current, previous, or lower dose of study drug. Each planned dose escalation cohort (Cohorts 1-3) will include 8 subjects randomized 3:1 to receive active drug or placebo. Starting with the lowest dose, each cohort of subjects will receive once daily oral BT051 or placebo for a period of 28 days. Follow-up visits will be performed at 7 and 30 days after the last dose. ;
