TL;DR: Patients with Crohn's disease who respond to an initial dose of infliximab are more likely to be in remission at weeks 30 and 54, to discontinue corticosteroids, and to maintain their response for a longer period of time, if inflIXimab treatment is maintained every 8 weeks.
Journal ArticleDOI

TL;DR: Patients with moderate-to-severe active ulcerative colitis treated with infliximab at weeks 0, 2, and 6 and every eight weeks thereafter were more likely to have a clinical response at weeks 8, 30, and 54 than were those receiving placebo.
Journal ArticleDOI

Paul Rutgeerts,Brian G. Feagan,Gary R. Lichtenstein,Lloyd Mayer,Stefan Schreiber,Jean-Frederic Colombel,Daniel Rachmilewitz,Douglas C. Wolf,Allan Olson,Weihang Bao,Stephen B. Hanauer +10 more
TL;DR: The scheduled infliximab groups, particularly the 10 mg/kg group, had better CDAI and Inflammatory Bowel Disease Questionnaire (IBDQ) responses than those in the episodic group.

Stephen B. Hanauer,Carrie L Wagner,Mohan Bala,Lloyd Mayer,Suzanne Travers,Robert H. Diamond,Allan Olson,Warren Bao,Paul Rutgeerts +8 more
TL;DR: Reduced antibody formation and greater clinical benefit were observed with an induction regimen followed by maintenance treatment compared with a single dose followed by episodic retreatment in Crohn's disease patients treated with infliximab.
Journal ArticleDOI
