Etrasimod Dose-Ranging Versus Placebo as Induction Therapy Study in Adult Japanese Subjects With Moderately to Severely Active Ulcerative Colitis

October 3, 2024 updated by: Pfizer

A Phase 2, Randomized, Double-Blind, Placebo-Controlled, 12-Week Dose-Ranging Study to Assess the Efficacy and Safety of Etrasimod in Japanese Participants With Moderately to Severely Active Ulcerative Colitis

The purpose of this Japan-only study is to assess the safety and efficacy of etrasimod at 2 doses in Japanese subjects with moderately to severely active ulcerative colitis (UC) when administered for 12 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Achieved Clinical Remission at Week 12
Time Frame: Week 12
Clinical remission:Participants with stool frequency (SF)subscore=0(or of 1 with greater than or equal to(>=)1 point decrease from baseline,rectal bleeding(RB)subscore=0 and endoscopic score(ES)less than or equal to(<)=1(excluding friability).SF subscore:number of stools in 24-hours relative to normal number of stools for that participant in same period,score ranged from 0(normal number of stools) to 3(5 or more stools than normal),higher scores=more severity.RB subscore:most severe amount of blood passed per rectum in 24-hours,score ranged from 0(no blood seen)to 3(blood alone passes),higher scores=more severity.ES:reported worst appearance of mucosa on flexible sigmoidoscopy or colonoscopy,score ranged from 0(normal or inactive disease) to 3(severe disease [spontaneous bleeding,ulceration]),higher scores=more severity.Modified Mayo score:measure disease activity for UC,score:0(normal) to 9(maximum severity),comprised subscores for SF,RB,ES.higher score=more severe disease activity.
Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Achieved Endoscopic Improvement at Week 12
Time Frame: Week 12
Endoscopic improvement was defined as ES <= 1 (excluding friability). ES reported worst appearance of mucosa on flexible sigmoidoscopy or colonoscopy, score ranged from 0 (normal or inactive disease) to 3 (severe disease [spontaneous bleeding, ulceration]), higher scores = more severity. Modified Mayo score (MMS): measure disease activity for UC, score: 0 (normal) to 9 (maximum severity),and comprised the subscores for SF, RB, ES. Higher score = more severe disease activity.
Week 12
Percentage of Participants Who Achieved Symptomatic Remission at Week 12
Time Frame: Week 12
Symptomatic remission was defined as SF sub score = 0 (or = 1 with a >= 1 point decrease from baseline) and RB sub score = 0. SF subscore: reported number of stools in a 24-hour period relative to normal number of stools for that participant in the same period, score ranged from 0 (normal number of stools) to 3 (5 or more stools than normal), higher scores = more severity. RB subscore: reported the most severe amount of blood passed per rectum in a 24-hour period, score ranged from 0 (no blood seen) to 3 (blood alone passes), higher scores = more severity. MMS: measure disease activity for UC, score: 0 (normal) to 9 (maximum severity), and comprised the subscores for SF, RB, ES. Higher score = more severe disease activity.
Week 12
Percentage of Participants Who Achieved Mucosal Healing at Week 12
Time Frame: Week 12
Mucosal healing was defined as ES <= 1 (excluding friability) with histologic remission defined as a Geboes index score < 2.0). ES reported worst appearance of mucosa on flexible sigmoidoscopy or colonoscopy, score ranged from 0 (normal or inactive disease) to 3 (severe disease [spontaneous bleeding, ulceration]), higher scores = more severity. The Geboes score grading system, was a validated score for evaluating histologic disease activity in UC as follows: grade 0 = structural and architectural changes; grade 1 = chronic inflammatory infiltrate; grade 2 = lamina propria neutrophils and eosinophils; grade 3 = neutrophils in the epithelium; grade 4 = crypt destruction; grade 5 = erosions or ulceration. A higher Geboes score indicated more severe disease. Modified Mayo score (MMS): measure disease activity for UC, score: 0 (normal) to 9 (maximum severity), comprised subscores for SF, RB, ES. Higher score = more severe disease activity.
Week 12
Percentage of Participants Who Achieved Clinical Response at Week 12
Time Frame: Week 12
Clinical response was defined as a >= 2-point and >= 30 percentage (%) decrease from baseline in MMS, and a >= 1-point decrease from baseline in RB subscore or an absolute RB subscore <= 1. MMS: measure disease activity for UC, score: 0 (normal) to 9 (maximum severity), and comprised the subscores for SF, RB, ES. Higher score = more severe disease activity. RB subscore: reported the most severe amount of blood passed per rectum in a 24-hour period, score ranged from 0 (no blood seen) to 3 (blood alone passes), higher scores = more severity.
Week 12
Percentage of Participants Who Achieved Endoscopic Normalization at Week 12
Time Frame: Week 12
Endoscopic normalization was defined as ES= 0. ES reported worst appearance of mucosa on flexible sigmoidoscopy or colonoscopy, score ranged from 0 (normal or inactive disease) to 3 (severe disease [spontaneous bleeding, ulceration]), higher scores = more severity. MMS: measure disease activity for UC, score: 0 (normal) to 9 (maximum severity), and comprised the subscores for SF, RB, ES. Higher score = more severe disease activity.
Week 12

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events According to Severity
Time Frame: Day 1 of first dose of study treatment up to 4 weeks after administration of the final dose of study treatment (maximum up to 16 weeks)
An adverse event was any untoward medical occurrence in a participant or clinical investigational participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. An adverse event was therefore any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Severity was classified using common terminology criteria for adverse events (CTCAE), version 5.0, such as Grade 1 for mild, Grade 2 for moderate, Grade 3 for severe, Grade 4 for life-threatening, Grade 5 for death related to adverse event.
Day 1 of first dose of study treatment up to 4 weeks after administration of the final dose of study treatment (maximum up to 16 weeks)
