A Study to Assess Real-world Outcomes for Long-Term Use of Guselkumab

Persistence with guselkumab will be measured through time to discontinuation (defined as time at which the next infusion should have taken place for a participant after their last scheduled infusion).

Number of participants with early responses to guselkumab will be assessed using PRO-2 components and reported via participant diaries. Measurements captured include stool frequency, rectal bleeding, and abdominal pain.

HBI score is used to assess disease severity and treatment effectiveness. The HBI consists of a 5-part questionnaire, assessing general wellbeing, abdominal pain, number of liquid stools per day, abdominal mass and complications. Clinical response for CD is defined as the HBI score less than or equal to (<=) 4 or a decrease in HBI by greater than or equal to (>=) 3 from baseline.

An adverse event is any untoward medical occurrence in a participant administered a medicinal product based on appropriate medical judgment. An AE does not necessarily have a causal relationship with the treatment. An adverse event can be any unfavorable and unintended sign (including an abnormal finding or lack of expected pharmacological action), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to that medicinal product.

An adverse event is any untoward medical occurrence in a participant administered a medicinal product based on appropriate medical judgment. An AE does not necessarily have a causal relationship with the treatment. An adverse event is considered drug-related if there is at least a reasonable possibility that the study drug contributed to the event.

An adverse event is any untoward medical occurrence in a participant administered a medicinal product based on appropriate medical judgment. An AE does not necessarily have a causal relationship with the treatment. An SAE is any event that results in death, is life-threatening, requires or prolongs hospitalization, causes significant disability, or is otherwise medically significant.

CRP normalization is defined as as <= 5 milligrams/litre (mg/L) since baseline (among participants with elevated CRP at Baseline).

Change in CRP levels since guselkumab initiation will be reported.

Number of participants with fecal calprotectin normalization will be reported. Normalization is defined as percentage of fecal calprotectin (fCAL) <=250 micrograms/gram (mcg/g) since baseline (among participants with Calprotectin elevation at Baseline).

Change in Fecal calprotectin levels since guselkumab initiation will be reported.

Change in Leukocytes count will be reported.

Change in hemoglobin levels to assess anaemia will be reported.

Change in transferrin saturation Levels to assess anaemia will be reported.

Change in Ferritin Levels to assess anaemia will be reported.

Change from baseline in HRQoL for CD will be measured by PRO-2 components. The CD PRO-2 consists of 2 items: abdominal pain (AP) and stool frequency (SF). AP is a numeric variable with a score between 0-3 and is self-reported by the participant for the 3 days preceding assessment as 0 (no pain), 1 (mild), 2 (moderate) or 3 (severe pain). SF is also a numeric variable calculated the number of liquid stools a participant has experienced over the past 3 days.

Change from baseline in HRQoL for UC will be measured by PRO-2 components. The UC PRO-2 is composed of rectal bleeding and stool frequency. Rectal bleeding is a numeric variable with a score between 0-3 and is self-reported by the participants for the 3 days preceding assessment as 0 (None), 1 (Streaks of blood with stool in less than half of the cases), 2 (Obvious blood with stools in most cases) or 3 (Blood alone passes). SF is also a numeric variable calculated the number of liquid stools a participant has experienced over the past 3 days.
