Oral Etrasimod Versus Placebo for the Treatment of Moderately to Severely Active Ulcerative Colitis in Adult Japanese Participants (ELEVATE UC 40 JAPAN)

September 22, 2023 updated by: Pfizer

A Phase 3, Double-Blind, Placebo-Controlled, 40-Week Extension Study to Assess the Efficacy and Safety of Etrasimod in Japanese Subjects With Moderately to Severely Active Ulcerative Colitis

The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment in adult Japanese participants with moderately to severely active ulcerative colitis (UC). This study is an extension of study APD334-302 (NCT03996369). Participants will continue with the same blinded treatment assigned in Study APD334-302 for a total treatment duration of 52 weeks (12 weeks in Study APD334-302 plus 40 weeks in Study APD334-308).

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 Achieving Clinical Remission at Week 40 of Study APD334-308
Time Frame: Week 40 of APD334-308
Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.
Week 40 of APD334-308

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 Achieving Endoscopic Improvement at Week 40 of Study APD334-308
Time Frame: Week 40 of APD334-308
Endoscopic improvement was defined as an ES <=1 (excluding friability) at Week 40 of APD334-308 compared with Week 12 of APD334-302. The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease); higher score indicated more severe disease.
Week 40 of APD334-308
Percentage of Participants Achieving Symptomatic Remission at Week 40 of Study APD334-308
Time Frame: Week 40 of APD334-308
Symptomatic remission was defined as an SF sub-score = 0 (or = 1 with a >= 1 point decrease from Baseline) and RB sub-score = 0. The SF sub-score ranged from 0 to 3 (where 0 = normal number of stools and 3 = at least 5 stools more than normal) and RB sub-score ranged from 0 to 3 (where 0 = no blood and 3 = blood alone passes). Higher scores indicated more severe disease.
Week 40 of APD334-308
Percentage of Participants With Mucosal Healing at Week 40 of Study APD334-308
Time Frame: Week 40 of APD334-308
Mucosal healing was defined as an ES <= 1 (excluding friability) with histologic remission measured by a Geboes Index score less than [<] 2.0). The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease). 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.
Week 40 of APD334-308
Percentage of Participants, Who Had Not Been Receiving Corticosteroids for ≥ 12 Weeks, Achieving Clinical Remission at Week 40 of Study APD334-308 Among Participants Receiving Corticosteroids at C5041015 (APD334-302) Study Entry
Time Frame: Week 40 of APD334-308
Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.
Week 40 of APD334-308
Percentage of Participants Achieving Sustained Clinical Remission
Time Frame: Week 40 of APD334-308
Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease. A subject with sustained clinical remission is defined as someone who achieved clinical remission at both Week 12 of APD334-302 and Week 40 of APD334-308.
