Clinical Trial Summary

The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of vixarelimab compared with placebo in participants with moderate to severe UC who have demonstrated inadequate response to, loss of response to, or intolerance to prior conventional or advanced therapy.

Description:

This study consists of two periods: 1. An induction period which will test the induction of clinical remission; 2. An optional active treatment extension (ATE) period which will explore durability of clinical response and remission in which all participants will receive vixarelimab.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of Participants with Clinical Remission	Clinical remission is defined as the Modified Mayo Score (mMS) of = 2, including stool frequency subscore of = 1, rectal bleeding subscore of 0, and endoscopy subscore of = 1. The mMS is a composite of stool frequency, rectal bleeding, and endoscopy with each component having a scoring range of 0-3. The mMS has a total score range of 0-9 with higher scores indicating greater disease severity.	Week 12
Secondary	Proportion of Participants with Clinical Response	Clinical response is defined as decrease from baseline in the mMS by =2 and = 30% reduction from baseline, with either a decrease of =1 in the rectal bleeding subscore or an absolute rectal bleeding subscore of =1. The mMS is a composite of stool frequency, rectal bleeding, and endoscopy with each component having a scoring range of 0-3. The mMS has a total score range of 0-9 with higher scores indicating greater disease severity.	Week 12
Secondary	Proportion of Participants with Endoscopic Improvement	Endoscopic improvement is defined as a Mayo endoscopy subscore of = 1. Mayo endoscopy subscore has a score range of 0 (normal appearance of mucosa) to 3 (severe disease).	Week 12
Secondary	Proportion of Participants with Endoscopic Remission	Endoscopic remission is defined as a Mayo endoscopy subscore of 0. Mayo endoscopy subscore has a score range of 0 (normal appearance of mucosa) to 3 (severe disease).	Week 12
Secondary	Number of Participants With Adverse Events (AE) by Severity	The AEs will be graded according to the Division of AIDS (DAIDS) table for grading the severity. The toxicity level is graded from grade 1 (lowest toxicity) to 4 (highest toxicity).	Up to Week 56
Secondary	Serum Concentration of Vixarelimab		Up to Week 56
Secondary	Proportion of Participants With Anti-drug Antibodies (ADAs) to Vixarelimab		Up to Week 56
