Clinical Study of TA-650 in Pediatric Patients With Ulcerative Colitis

Phase 3
Completed
Conditions
Pediatric Ulcerative Colitis
Interventions
Registration Number
NCT01585155
Lead Sponsor
Mitsubishi Tanabe Pharma Corporation
Brief Summary

The purpose of this study is to evaluate the the efficacy of TA-650 using Clinical activity index (CAI) score and other evaluation indicators in pediatric patients with moderate to severe ulcerative colitis after TA-650 administration of at a dose of 5 mg/kg at weeks 0, 2, and 6, and then every 8 weeks at weeks 14 and 22. The safety and pharmacokinetics are also evaluated.

Primary Outcome Measures
NameTimeMethod
Percent of Patients Who Achieved CAI RemissionWeeks 2, 6, 8, 10, 14, 18, 22, 26, 30, and the last time point during the period from administration of the study drug to Week 30

Clinical activity index (CAI) remission was defined as a case where a CAI score was not more than 4 on the evaluation day.

CAI score was an activity index to evaluate disease activity, which is calculated as the sum (0 to 29 points) of subscores for 7 clinical conditions, consisting of the number of stools per week, blood in stools (based on weekly average), investigator's global assessment of the symptomatic state, abdominal pain/cramps, temperature elevation due to ulcerative colitis, extraintestinal manifestations, and laboratory findings (hemoglobin or ESR). A higher score indicates greater disease activity.

Secondary Outcome Measures
NameTimeMethod
CAI ScoreBaseline,Weeks 2, 6, 8, 10, 14, 18, 22, 26, 30, and the last time point during the period from administration of the study drug to Week 30

CAI score was an activity index to evaluate disease activity, which is calculated as the sum (0 to 29 points) of subscores for 7 clinical conditions, consisting of the number of stools per week, blood in stools (based on weekly average), investigator's global assessment of the symptomatic state, abdominal pain/cramps, temperature elevation due to ulcerative colitis, extraintestinal manifestations, and laboratory findings (hemoglobin or ESR). A higher score indicates greater disease activity.

Pediatric Ulcerative Colitis Activity Index (PUCAI) ScoreBaseline,Weeks 2, 6, 8, 10, 14, 18, 22, 26, 30, and the last time point during the period from administration of the study drug to Week 30

PUCAI score was determined as a total of the subscores for each of the six evaluation items (0 to 85), including abdominal pain, rectal bleeding, stool consistency of most stools, number of stools per 24 hours, nocturnal stools and activity level. A higher score indicates greater disease activity.

Partial Mayo ScoreBaseline,Weeks 2, 6, 8, 10, 14, 18, 22, 26, 30, and the last time point during the period from administration of the study drug to Week 30

Mayo score consists of four subscores (stool frequency, rectal bleeding, physician's global assessment and findings of endoscopy), each of which was assessed according to a four-level rating scale (0 to 3 points), and was determined from a total of the four subscores (0 to 12 points). In addition, the sum of the subscores (0 to 9 points) for stool frequency, rectal bleeding and physician's global assessment was used as a partial Mayo score. A higher score indicates greater disease activity.
