Information provided by (Responsible Party):
AstraZeneca
  Purpose
The study is designed to evaluate the clinical efficacy and safety of tralokinumab as compared to placebo. Investigational product will be administered as subcutaneous injection. All patients will continue background therapy for ulcerative colitis as per local standards of care in addition to investigational product.

Condition Intervention Phase
Ulcerative Colitis Drug: tralokinumab Drug: placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase IIa, Randomised, Double-blind, Placebo-controlled, Parallel-arm, Multicenter Study to Evaluate the Efficacy and Safety of Tralokinumab (CAT-354), a Recombinant Human Monoclonal Antibody Directed Against Interleukin-13 (IL-13), as add-on Therapy, on Clinical Response in Patients With Active, Moderate-to-severe, Ulcerative Colitis

Primary Outcome Measures:
  • Clinical Response at Week 8 Based on Mayo Score [ Time Frame: Eight week treatment period ]
    Clinical response was measured as a decrease in Mayo score of ≥3 points from baseline, decrease in the total Mayo score from baseline ≥30 percentage and a decrease in the sub score for rectal bleeding ≥1 or absolute sub score for rectal bleeding of 0 or 1 point. Mayo score is sum of four sub-scores: stool frequency, rectal bleeding, endoscopy findings and the physician's global assessment. The total Mayo score ranges from 0-12, with higher scores indicating a more severe disease.


Secondary Outcome Measures:
  • Change in Mayo Score From Baseline to Week 8 [ Time Frame: Eight week treatment period ]
    Mayo score is sum of four sub-scores: stool frequency, rectal bleeding, endoscopy findings and the physician's global assessment. The total Mayo score ranges from 0-12, with higher scores indicating a more severe disease. Change from baseline: Mayo score at week 8 minus the Mayo score at baseline.

  • Mucosal Healing at Week 8 Based on Mayo Score [ Time Frame: Eight week treatment period ]
    Improvement of the endoscopy sub score (from the Mayo score) from 3 or 2 to 0 or 1 point, or from 1 to 0 points.

  • Clinical Remission at Week 8 Based on Mayo Score [ Time Frame: Eight week treatment period ]
    Participants were classified as in remission if Mayo score of ≤2 with no individual sub score exceeding 1 point. Mayo score is sum of four sub-scores: stool frequency, rectal bleeding, endoscopy findings and the physician's global assessment. The total Mayo score ranges from 0-12, with higher scores indicating a more severe disease.

  • Change From Baseline in Partial Mayo Score [ Time Frame: From baseline to Week 4, 8, 12, 16, 20, and 24. ]
    The partial Mayo score is the sum of the three sub-score areas: stool frequency, rectal bleeding, and the physician's global assessment.The partial Mayo score ranges from 0-9, with higher scores indicating a more severe disease. Change from baseline: Mayo score at each post-baseline timepoint (week 4, 8, 12, 16, 20, and 24) minus the Mayo score at baseline.

  • Change From Baseline in Modified Riley Score [ Time Frame: Eight week treatment period ]
    Modified Riley score is biopsy grade which range from 0-5; where 0: Normal mucosa, 1: Infiltration of lymphocytes and plasma cells in the lamina propria, 2: Infiltration of neutrophils and eosinophils in the lamina propria, 3: Infiltration of neutrophils in the epithelium, 4: Crypt destruction, 5: Erosion and/or ulceration.

  • Change From Baseline in C - Reactive Protein [ Time Frame: From baseline to Week 4, 8, 12, 16, 20, and 24. ]
  • Change From Baseline in Albumin [ Time Frame: From baseline to Week 4, 8, 12, 16, 20, and 24. ]
  • Change From Baseline in Calprotectin [ Time Frame: From baseline to Week 4, 8, 12, 16, 20, and 24. ]
  • Serum Concentration of Tralokinumab [ Time Frame: Pre-dose sampling at baseline, Week 4, 8, 12, 16, 20, and 24. ]
  • Immunogenicity [ Time Frame: Pre-dose sampling at baseline, Week 8, 12, 16, and 24. ]
    Incidence of anti-drug antibodies (ADA) to tralokinumab in serum.
