2026年11月2日 更新者:Xian-Janssen Pharmaceutical Ltd.

ウステキヌマブへの反応喪失後の中国人クローン病患者におけるガセルクマブの有効性

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.

主要な結果の測定

メジャーの説明
時間枠
Percentage of Participants Achieving Clinical Remission At Week 48
時間枠: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.

時間枠: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.

Percentage of Participants Achieving Clinical Remission At Weeks 12 and 24
時間枠:At Weeks 12 and 24

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
時間枠: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
時間枠: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.
