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

October 23, 2019 updated by: Mitsubishi Tanabe Pharma Corporation

Clinical Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of TA-650 in Pediatric Patients With Moderate to Severe Ulcerative Colitis.

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.

Description

Inclusion Criteria:

  • Patients who have been diagnosed as ulcerative colitis at least 3 months prior to screening.
  • Have active ulcerative colitis despite adequate conventional therapy.

Exclusion Criteria:

  • Patients who have severe pancolitis.
  • Patients who have undergone surgery for ulcerative colitis within 8 weeks before enrollment or who were judged to require surgery for ulcerative colitis at enrollment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: TA-650
TA-650 will be intravenously infused at 5 mg/kg as an induction regimen at Weeks 0, 2, 6. For subjects who meet the responder criteria, TA-650 will be administered at 8-week intervals thereafter until week 22.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent of Patients Who Achieved CAI Remission
Time Frame: 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

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.

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).

Baseline,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
Partial Mayo Score
Time Frame: Baseline,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.
Baseline,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
Pediatric Ulcerative Colitis Activity Index (PUCAI) Score
Time Frame: Baseline,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.
Baseline,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
