A Study to Evaluate the Safety and Efficacy of Ustekinumab Induction and Maintenance Therapy in Participants With Moderately to Severely Active Ulcerative Colitis

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and safety of ustekinumab as intravenous (IV: into the vein) infusion in induction study in participants with moderately to severely active Ulcerative Colitis (UC) and as subcutaneous (SC) administration in maintenance study in participants with moderately to severely active Ulcerative Colitis (UC) who have demonstrated a clinical response to Induction treatment with IV ustekinumab.

Detailed Description
-----------------
This is a Phase 3, randomized (assignment of study drug by chance), double-blind (neither the participant or study staff will know the identity of study drugs), placebo-controlled (placebo is an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial), parallel-group (a medical research study comparing the response in 2 or more groups of participants receiving different interventions), multi-center (more than one clinical site will work on a medical research study), protocol of ustekinumab. The protocol will consist of 2 studies: an Induction study and a Maintenance study with unique endpoints. Screening period will be up to 8 Weeks. Induction study will be at least 8 weeks duration for each participant. Participant with clinical response in the Induction study will be eligible for the Maintenance study. The Maintenance study will be 44 weeks duration. After completion of the maintenance study, a long term extension will follow eligible participants for an additional 3 years. Clinical remission will be evaluated at Week 8 in the Induction study. Clinical remission among ustekinumab Induction responders will be evaluated at week 44 in the Maintenance study. Participants' safety will be monitored throughout.

| --- | --- | --- |
| Induction Study - Number of Participants With Clinical Remission at Week 8 (As Per Global Definition) | As per global definition, clinical remission is defined as a Mayo score less than or equal to (<=)2 points, with no individual subscore greater than (>)1. The Mayo score consists of 4 subscores (stool frequency, rectal bleeding [RB], endoscopy findings, and physician's global assessment [PGA]), rated as 0 (normal) to 3 (severe). Total score was calculated as the sum of 4 subscores and values range from 0 to 12 scores, where 3 to 5 = mild; 6 to 10 = moderate; and 11 to 12 = severe; higher scores indicate worsening of the disease. Participants who had a prohibited change in concomitant ulcerative colitis (UC) medication or an ostomy or colectomy prior to the Week 8 or who had all 4 Mayo subscores missing at Week 8 were considered not to be in clinical remission. Endoscopy subscore as assessed during central review of video of endoscopy was used. | Week 8 | 
| Induction Study - Number of Participants With Clinical Remission at Week 8 (As Per US Definition) | As per US definition, clinical remission was defined as absolute stool number <=3, a Mayo rectal bleeding subscore of 0 (no blood seen), and a Mayo endoscopy subscore of 0 (normal or inactive disease) or 1 (mild disease [erythema, decreased vascular pattern, mild friability]) without the physician's global assessment. Absolute stool number is average of daily stool number over the three days. The Mayo rectal bleeding and endoscopy findings subscores were rated as 0 (normal) to 3 (severe). Participants who had a prohibited change in concomitant UC medication or an ostomy or colectomy prior to the Week 8 or who were missing all 3 of the Mayo components pertaining to this outcome measure (OM) (absolute stool number, rectal bleeding subscore, and Mayo endoscopy subscore) at Week 8 were considered not to be in clinical remission.

The 32 items were grouped into 4 domains: bowel function, emotional status, systemic symptoms and social function. The 4 domains were scored as follows: 10 to 70 (bowel symptoms); 5 to 35 (systemic symptoms); 12 to 84 (emotional function); and 5 to 35 (social function). For each domain, higher score indicated better quality of life. Total score is sum of each item score and ranges from 32 to 224 with higher score indicating better quality of life. Participants who had prohibited change in concomitant UC medication or ostomy or colectomy prior to the Week 44 had their Week 0 value of the induction study carried forward from the time of the event onward and participants who had a missing IBDQ score at a timepoint had their last value carried forward. | Baseline, Week 20, and 44 | 
| Maintenance Study: Change From Maintenance Baseline in the IBDQ Dimension Scores at Week 20 and 44 | The IBDQ is 32-item questionnaire for participants with IBD used to evaluate disease-specific health-related quality of life. IBDQ consists of 32 items, each item score ranged from 1 (worst possible response) to 7 (best possible response). The 32 items were grouped into 4 domains: bowel function, emotional status, systemic symptoms and social function. The 4 domains were scored as: 10 to 70 (bowel symptoms); 5 to 35 (systemic symptoms); 12 to 84 (emotional function); 5 to 35 (social function). For each domain, higher score indicated better quality of life. Total score is sum of each item score and ranges from 32 to 224 with higher score indicating better quality of life. Participants who had prohibited change in concomitant UC medication or ostomy or colectomy prior to Week 44 had their Week 0 value of induction study carried forward from time of event onward and participants who had missing IBDQ dimension score at a timepoint had their last available value carried forward. | Baseline, Week 20, and 44 | 
| Maintenance Study: Change From Maintenance Baseline in 36-Item Short-Form (SF-36) Physical Component Score (PCS) and Mental Component Score (MCS) at Weeks 20 and 44 | SF-36 evaluates 8 individual subscales (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health). Each 8 scales scored from 0 to 100 with higher scores= better health. Based on scale scores, PCS (calculated from subscales physical functioning, role-physical, bodily pain, and general health) and MCS (calculated from subscales vitality, social functioning, role-emotional and mental health) scores were derived. Summary MCS and PCS score is also scaled from 0 to 100 with higher scores= better health. Participants with prohibited change in concomitant UC medication/ ostomy/ colectomy/ used rescue medication after clinical flare/ discontinued study agent due to lack of therapeutic effect/ due to AE of worsening of UC before Week 44 had Week 0 value of IS carried forward from time of event onward and participants with missing component summary score at timepoint had last available value carried forward. | Baseline, Weeks 20, and 44 | 
| Maintenance Study: Change From Maintenance Baseline in Individual Subscales of 36-Item Short-Form (SF-36) at Weeks 20 and 44 | SF-36 evaluates 8 individual subscales (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health). Each 8 scales scored from 0 to 100 with higher scores= better health. Participants who had prohibited change in concomitant UC medication/ ostomy/ colectomy/ used rescue medication after clinical flare, or discontinued study agent due to lack of therapeutic effect or due to AE of worsening of UC prior to Week 44 had Week 0 value of induction study carried forward from time of event onward and participants with missing individual scale score at timepoint had last available value carried forward. | Baseline, Weeks 20, and 44 | 
| Maintenance Study: Change From Maintenance Baseline in EuroQOL-5 Dimensions (EQ-5D) Health Questionnaire Index Score at Weeks 20 and 44 | EQ-5D descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). The responses to 5 EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 (death) to 1 (full health). Participants who had a prohibited change in concomitant UC medication or an ostomy or colectomy, or used a rescue medication after clinical flare, or discontinued study agent due to lack of therapeutic effect or due to an AE of worsening of UC prior to the Week 44 had their Week 0 value of the induction study carried forward from the time of the event onward and participants who had a missing individual scale score at a timepoint had their last available value carried forward. | Baseline, Weeks 20, and 44 | 
| Maintenance Study: Change From Maintenance Baseline in EuroQOL-5 (EQ-5D) Health State Visual Analog Scale (VAS) Score at Weeks 20 and 44 | The EQ-5D VAS records the participant's self-rated health on a vertical, VAS, with 0 representing the worst imaginable health state and 100 representing the best imaginable health state. The EQ VAS is used as a quantitative measure of health outcome as judged by the individual participant. Participants who had a prohibited change in concomitant UC medication or an ostomy or colectomy, or used a rescue medication after clinical flare, or discontinued study agent due to lack of therapeutic effect or due to an AE of worsening of UC prior to the Week 44 had their Week 0 value of the induction study carried forward from the time of the event onward and participants who had a missing VAS score at a timepoint had their last available value carried forward. | Baseline, Weeks 20 and 44 | 
| Maintenance Study: Percentage of Participants With Change From Maintenance Baseline in EuroQOL-5 (EQ-5D) Dimensions Score at Weeks 20 and 44 | EQ-5D descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). The responses to 5 EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 (death) to 1 (full health).
