Design outcomes

Primary

MeasureTime frameDescription
Percentage of Patients Achieving Clinical Remission at Week 54Week 54Clinical remission defined by modified Mayo score which ranges from 0 to 9, including Stool frequency subscore, Rectal bleeding subscore and Endoscopic subscore but excluding Physician's global assessment subscore from the Total Mayo score. Patients with dose adjustment to CT-P13 SC 240 mg prior to Week 54 were considered as non-remitter.

Secondary

MeasureTime frameDescription
Percentage Patients Achieving Clinical Response at Week 54Week 54Clinical response defined by decrease in modified Mayo score from baseline of at least 2 points and at least 30%, with an accompanying decrease in the rectal bleeding subscore of at least 1 point or an absolute rectal bleeding subscore of 0 or 1 point. Patients with dose adjustment to CT-P13 SC 240 mg prior to Week 54 were considered as non-responder.
Percentage of Patients Achieving Endoscopic-Histologic Mucosal Improvement at Week 54Week 54Endoscopic-histologic mucosal improvement defined as an absolute endoscopic subscore of 0 or 1 point from modified Mayo score and an absolute RHI score of 3 points or less with an accompanying lamina propria neutrophils and neutrophils in epithelium subscore of 0 point. Patients with dose adjustment to CT-P13 SC 240 mg prior to Week 54 were considered as endoscopic-histologic mucosal improvement not achieved.
Percentage of Patients Achieving Corticosteroid-Free Remission at Week 54Week 54Corticosteroid-free remission defined as being in clinical remission by modified Mayo score in addition to not requiring any treatment with corticosteroid for at least 8 weeks at Week 54, among the patients who used oral corticosteroids at baseline. Patients with dose adjustment to CT-P13 SC 240 mg prior to Week 54 were considered as non-remitter.
