En studie för att utvärdera effekten av Guselkumab hos kinesiska deltagare med Crohns sjukdom (CD)

2 november 2026 uppdaterad av: Xian-Janssen Pharmaceutical Ltd.

Effektiviteten av Guselkumab hos kinesiska deltagare med Crohns sjukdom efter förlust av respons på Ustekinumab

The purpose of this study is to evaluate how well guselkumab works in participants with Crohn's disease (CD; a long-term condition causing severe inflammation of the intestinal tract) who no longer respond to treatment with ustekinumab.

Åtgärdsbeskrivning
Tidsram
Percentage of Participants Achieving Clinical Remission At Week 48
Tidsram: At Week 48

Clinical remission is defined as less than (<) 150-point reduction in Crohn's Disease Activity Index (CDAI) score. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.

Tidsram
Percentage of Participants Achieving Clinical Response At Weeks 12, 24 and 48
Tidsram: At Weeks 12, 24 and 48

Clinical response is defined as greater than or equal to (>=) 100-point reduction from baseline in CDAI score. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.

Clinical remission is defined as < 150-point reduction in CDAI score. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
At Weeks 12 and 24
Percentage of Participants Achieving Endoscopic Response
Tidsram: At Weeks 24 and 48

Endoscopic response is defined as >= 50% improvement from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) score. The SES-CD is based on the evaluation of 4 variables: (ulcers - scored according to size, proportion of the surface covered by ulcers according to extent, proportion of affected surface with any other lesions according to extent, stenosis [single or multiple, and whether the colonoscopy could pass through the narrow lumen]), each considered in 5 segments of the bowel (the ileum, ascending colon, transverse colon, descending colon, and rectum). An overall total SES-CD score is derived from the sum of all the component scores and can range from 0 to 60. Higher scores indicating severe disease.
At Weeks 24 and 48
Percentage of Participants Achieving Endoscopic Remission
Tidsram: At Weeks 24 and 48

Endoscopic remission is defined as SES-CD less than or equal to (<=) 2 in any individual component. The SES-CD is based on the evaluation of 4 variables: (ulcers - scored according to size, proportion of the surface covered by ulcers according to extent, proportion of affected surface with any other lesions according to extent, stenosis [single or multiple, and whether the colonoscopy could pass through the narrow lumen]), each considered in 5 segments of the bowel (the ileum, ascending colon, transverse colon, descending colon, and rectum). An overall total SES-CD score is derived from the sum of all the component scores and can range from 0 to 60. Higher scores indicating severe disease.
