Trial Outcomes & Findings for Conventional Step-Up Versus Infliximab Monotherapy in Patients With Ulcerative Colitis (P05553) (NCT NCT00984568)

NCT ID: NCT00984568

Last Updated: 2017-04-13

Results Overview

Response at Week 4 was defined as a minimum decrease from baseline in Mayo score of 3 points and 30%. Steroid-free remission at Week 50 was defined as a total Mayo score (including endoscopic assessment) of 2 points or lower and no individual subscore exceeding 1. The Mayo score consists of the following 4 subscores: stool frequency; rectal bleeding; endoscopy results; physician's global assessment. Each subscore is rated on a scale from 0 (best) to 3 (worst). The total Mayo score is calculated as the sum of the 4 subscores and ranges from 0 (best) to 12 (worst).

SECONDARY outcome

Timeframe: Up to Week 4

Population: The full analysis set (FAS) consisted of all randomized participants who received at least one dose of study treatment.

Response was defined as a minimum decrease from baseline in total Mayo score of 3 points and 30% up to and including 4 weeks after the start of treatment. The Mayo score consists of the following 4 subscores: stool frequency; rectal bleeding; endoscopy results; physician's global assessment. Each subscore is rated on a scale from 0 (best) to 3 (worst). The total Mayo score is calculated as the sum of the 4 subscores and ranges from 0 (best) to 12 (worst).
