Brief summary

The purpose of this study is to assess the measurable changes in health, function, or quality of life (clinical outcomes) after receiving guselkumab in real-world clinical practice amongst Chinese participants with ulcerative colitis (UC; a long-term disease of the large intestine in which the lining of the colon \[part of large intestine\] becomes inflamed and develops tiny open ulcers), who have not received biologic therapy (a medicine made from living organisms or their components) previously.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants Achieving Clinical Response at Week 12At Week 12Clinical response is defined as a decrease from baseline in the partial Mayo score by \>= 30 percent (%) and \>= 2 points, with either a \>=1 decrease from baseline in rectal bleeding subscore (RBS) or an RBS of 0 or 1. Partial Mayo score is a non-invasive clinical measure for determining the severity of UC. The total score falls between 0 and 9, where higher score indicates more severity.

Secondary

MeasureTime frameDescription
Percentage of Participants Achieving Clinical Response at Week 24 and Week 48At Week 24 and Week 48Clinical response is defined as a decrease from baseline in the partial Mayo score by \>= 30 % and \>= 2 points, with either a \>=1 decrease from baseline in RBS or an RBS of 0 or 1. Partial Mayo score is a non-invasive clinical measure for determining the severity of UC. The total score falls between 0 and 9, where higher score indicates more severity.
Percentage of Participants Achieving Symptomatic Response at Week 2At Week 2Symptomatic response is defined as a decrease from induction baseline in the patient reported outcome (PRO)-2 by at least 30% and at least 1 point, with either at least 1-point decrease from induction baseline in RBS or an RBS of 0 or 1. PRO-2 consists of the two components (rectal bleeding and stool frequency). The stool frequency subscale is rated as follows: 0 (normal stool frequency), 1 (1-2 stools more than normal), 2 (3-4 stools more than normal), and 3 (5 or more stools more than normal). The rectal bleeding subscale is rated as: 0 (no blood), 1 (streaks of blood less than half the time), 2 (obvious blood most of the time), and 3 (blood alone). Higher score indicates more severity in symptoms.
Mean Change from Baseline in Stool Frequency Subscore (SFS) Over Week 2From Baseline to Week 2SFS is a component of PRO-2. The stool frequency subscale is rated as follows: 0 (normal stool frequency), 1 (1-2 stools more than normal), 2 (3-4 stools more than normal), and 3 (5 or more stools more than normal). Higher score indicates more severity in symptoms.
Mean Change from Baseline in RBS Over Week 2From Baseline to Week 2RBS is a component of PRO-2. The rectal bleeding subscale is rated as: 0 (no blood), 1 (streaks of blood less than half the time), 2 (obvious blood most of the time), and 3 (blood alone). Higher score indicates more severity in symptoms.
Percentage of Participants Achieving Clinical Remission at Week 12, Week 24 and Week 48At Week 12, Week 24 and Week 48Clinical remission is defined as a partial Mayo score less than or equal to (\<=) 2 with no sub-score greater than (\>) 1. Partial Mayo score is a non-invasive clinical measure for determining the severity of UC. The total score falls between 0 and 9, where higher score indicates more severity.
Percentage of Participants Achieving Symptomatic Remission at Week 2At Week 2Symptomatic remission as measured by PRO-2 is defined as a SFS of 0 or 1 and an RBS of 0, where the SFS has not increased from induction baseline. The SFS is rated as follows: 0 (normal stool frequency), 1 (1-2 stools more than normal), 2 (3-4 stools more than normal), and 3 (5 or more stools more than normal). The RBS is rated as: 0 (no blood), 1 (streaks of blood less than half the time), 2 (obvious blood most of the time), and 3 (blood alone). Higher score indicates more severity in symptoms.
Percentage of Participants Achieving Steroid-Free Remission at Week 12, 24 and 48At Weeks 12, 24 and 48Steroid-free remission is defined as clinical remission with no use of corticosteroids for at least 30 days. Clinical remission is defined as partial Mayo score \<= 2 with no sub-score \>1.
Percentage of Participants Achieving Sustained Remission at Week 24 and Week 48At Week 24 and Week 48Sustained remission is defined as clinical remission maintenance status at post-induction (Week 12) in participants who had attained clinical remission by the end of the 12-week induction therapy.
Percentage of Participants with Endoscopic Improvement (Healing) at Week 24 and Week 48At Week 24 and Week 48Endoscopic improvement (healing) is defined as endoscopic remission Mayo endoscopic subscore (MES) of 0 or 1. The MES consists of 3 subscores: stool frequency, rectal bleeding and physician's global assessment, each subscore is graded from 0 (normal) to 3 (severe) with higher scores indicate more severe disease.
Percentage of Participants Achieving Endoscopic Remission (Normalization) at Week 24 and Week 48At Week 24 and Week 48Endoscopic remission (normalization) is defined as an MES of 0. The MES consists of 3 subscores: stool frequency, rectal bleeding and physician's global assessment, each subscore is graded from 0 (normal) to 3 (severe) where higher scores indicate more severe disease.
Percentage of Participants Discontinuing from TreatmentUp to Week 48Treatment discontinuation is defined as discontinuation of guselkumab treatment for any reason.
Percentage of Participants Switching from TreatmentUp to Week 48Treatment switch is defined as initiation of another medication for UC treatment after guselkumab discontinuation.
Time to Treatment DiscontinuationUp to Week 48Time to treatment discontinuation is defined as the time from the guselkumab start date to the time of treatment discontinuation.
Time to Treatment SwitchUp to Week 48Time to treatment switch is defined as the time from the guselkumab start date to the time of initiation of a new treatment other than guselkumab.
Percentage of Participants on Guselkumab Dosing Schedules of 200 Milligrams (mg) Once Every 4 Weeks (q4w) or 100 mg Once Every 8 Weeks (q8w)From Baseline through Week 12 to Week 48The percentage of participants on guselkumab dosing schedules of 200mg q4w or 100 mg q8w will be assessed. For each dosing schedule, the percentage will be calculated by dividing the number of participants receiving the specific dosing regimen by the number of participants still being followed up at those time points, multiplied by 100%.
Percentage of Participants Undergoing Dose Escalation/ De-EscalationWeek 12 up to Week 48Percentage of participants having dose escalation/ de-escalation during maintenance treatment will be assessed. The percentage will be calculated by dividing the number of participants having dosage adjustment (that is, dose escalation/de-escalation) after Week 0 at any visit time point compared to his/her previous recorded administration dosage, multiplied by 100%.
Percentage of Participants Achieving Inflammatory Bowel Disease Questionnaire (IBDQ) RemissionAt Week 12, Week 24 and Week 48IBDQ remission is defined as total IBDQ score \>= 170. The IBDQ is a validated, 32-item, self-reported questionnaire for patients with inflammatory bowel disease that will be used to evaluate the disease-specific health-related quality of life (QoL) across 4 dimensional scores: bowel symptoms (loose stools, abdominal pain), systemic functions (fatigue, altered sleep pattern), social function (work attendance, need to cancel social events), and emotional function (anger, depression, irritability). Scores range from 32 to 224, with higher scores indicating better outcomes.
Change from Baseline in C-Reactive Protein (CRP) LevelsBaseline, Week 12, Week 24 and Week 48Change in CRP levels since guselkumab initiation will be reported.
Change from Baseline of Fecal Calprotectin LevelsBaseline, Week 12, Week 24 and Week 48Change in fecal calprotectin levels since guselkumab initiation will be reported.
Percentage of Participants Achieving CRP NormalizationAt Week 12, Week 24 and Week 48Normalization of CRP is defined as reduction of less than or equal to 5 microgram per liter (mg/L) at weeks 12, 24 and 48 since baseline. Percentage of participants with abnormal CRP at baseline achieving CRP normalization will be reported.
Percentage of Participants Achieving Fecal Calprotectin (FCP) NormalizationAt Week 12, Week 24 and Week 48Normalization of fecal calprotectin is defined as reduction of \<= 250 microgram per gram (mcg/g) at weeks 12, 24 and 48 since baseline. Percentage of participants with abnormal FCP at baseline achieving fecal calprotectin normalization will be reported.
