Brief summary

The primary objective of the study is to evaluate the efficacy of 2 different maintenance dose regimens of TEV-48574 subcutaneous (sc) administered every 4 weeks (Q4W) in adult participants with inflammatory bowel disease (IBD). Secondary objectives of the study are to: * evaluate the efficacy of 2 different maintenance dose regimens of TEV-48574 sc administered Q4W in adult participants with IBD * evaluate the safety and tolerability of 2 different maintenance dose regimens of TEV-48574 sc administered Q4W in adult participants with IBD * evaluate the immunogenicity of 2 different maintenance dose regimens of TEV-48574 sc administered Q4W in adult participants with IBD The total duration for a participant in the double-blind period only is 66 weeks; and for a participant in the open-label extension (OLE) period, up to an additional 268 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Number of participants with moderate to severe ulcerative colitis (UC) who show clinical remission as defined by the Mayo scoreWeek 44Clinical remission based on modified (9-point rectal bleeding, stool frequency, and endoscopy) Mayo score of ≤2 points, which is defined by: * stool frequency subscore of 0 or 1, * rectal bleeding subscore of 0, and * endoscopic subscore of 0 or 1, where a score of 1 does not include "friability"
Number of participants with moderate to severe Crohn's disease (CD) who show an endoscopic response as defined by the Endoscopic Score for Crohn's DiseaseWeek 44Endoscopic response, defined as a decrease in Simple Endoscopic Score for Crohn's Disease (SES-CD) of at least 50% from DRF study baseline at week 44 in participants with CD

Secondary

MeasureTime frameDescription
Number of participants with moderate to severe UC with a clinical response as defined by Mayo scoreWeek 44Clinical response at week 44, defined as a decrease from baseline in the modified (9-point rectal bleeding, stool frequency, and endoscopy) Mayo score of at least 2 points AND at least a 30% reduction from DRF baseline with either a decrease in rectal bleeding subscore of at least 1 or an absolute rectal bleeding subscore of less than or equal to 1
Number of participants with moderate to severe UC with Endoscopic improvement as defined by Mayo scoreWeek 44Endoscopic improvement defined as a Mayo endoscopic subscore of 0 or 1
