TL;DR: Adalimumab was safe and more effective than placebo in inducing and maintaining clinical remission in patients with moderate-to-severe ulcerative colitis who did not have an adequate response to conventional therapy with steroids or immunosuppressants.

TL;DR: Adalimumab induced and maintained clinical remission for up to 56 weeks in patients with moderate to severe Crohn’s disease naive to anti-TNF treatment in a follow-on randomised controlled trial.
Abstract: Background: Adalimumab induced clinical remission after four weeks in patients with active Crohn’s disease in the CLASSIC I trial. Objective: To evaluate long term efficacy and safety of adalimumab maintenance therapy in Crohn’s disease in a follow-on randomised controlled trial (CLASSIC II). Methods: In the preceding CLASSIC I trial, 299 patients with moderate to severe Crohn’s disease naive to tumour necrosis factor antagonists received induction therapy with adalimumab 40 mg/20 mg, 80 mg/40 mg, or 160 mg/80 mg, or placebo, at weeks 0 and 2. In all, 276 patients from CLASSIC I enrolled in CLASSIC II and received open-label adalimumab 40 mg at weeks 0 (week 4 of CLASSIC I) and 2; 55 patients in remission at both weeks 0 and 4 were re-randomised to adalimumab 40 mg every other week, 40 mg weekly, or placebo for 56 weeks. Patients not in remission at both weeks 0 and 4 were enrolled in an open-label arm and received adalimumab 40 mg every other week. With non-response or flare, these patients could have their dosages increased to 40 mg weekly. Patients in the randomised arm with continued non-response or disease flare could switch to open-label adalimumab 40 mg every other week and again to 40 mg weekly. The primary end point was maintenance of remission (CDAI Results: Of 55 patients randomised at week 4, 79% who received adalimumab 40 mg every other week and 83% who received 40 mg weekly were in remission at week 56, v 44% for placebo (p Conclusions: Adalimumab induced and maintained clinical remission for up to 56 weeks in patients with moderate to severe Crohn’s disease naive to anti-TNF treatment.

TL;DR: Response and remission rates for natalizumab were superior to those for placebo at Weeks 4, 8, and 12, demonstrating the early and sustained efficacy of natalIZumab as induction therapy in patients with elevated C-reactive protein and active Crohn's disease.

TL;DR: Scheduled infliximab maintenance therapy resulted in more improvement in mucosal ulceration and in higher rates of mucosal healing, and there was a numerical trend for patients with better mucosal Healing to have a lower rate of Crohn's disease-related hospitalizations.

TL;DR: Following induction therapy with adalimumab, patients with moderately to severely active CD who continue to receive adal optimumab are more likely to achieve mucosal healing than those given placebo.

TL;DR: Vedolizumab was more effective than placebo as induction and maintenance therapy for ulcerative colitis and the frequency of adverse events was similar in the vedolIZumab and placebo groups.
Abstract: We conducted two integrated randomized, double-blind, placebo-controlled trials of vedolizumab in patients with active disease. In the trial of induction therapy, 374 pa tients (cohort 1) received vedolizumab (at a dose of 300 mg) or placebo intravenously at weeks 0 and 2, and 521 patients (cohort 2) received open-label vedolizumab at weeks 0 and 2, with disease evaluation at week 6. In the trial of maintenance therapy, patients in either cohort who had a response to vedolizumab at week 6 were randomly assigned to continue receiving vedolizumab every 8 or 4 weeks or to switch to placebo for up to 52 weeks. A response was defined as a reduction in the Mayo Clinic score (range, 0 to 12, with higher scores indicating more active disease) of at least 3 points and a de crease of at least 30% from baseline, with an accompanying decrease in the rectal bleeding subscore of at least 1 point or an absolute rectal bleeding subscore of 0 or 1. Results Response rates at week 6 were 47.1% and 25.5% among patients in the vedolizumab group and placebo group, respectively (difference with adjustment for stratification factors, 21.7 percentage points; 95% confidence interval [CI], 11.6 to 31.7; P 1), as compared with 15.9% of pa tients who switched to placebo (adjusted difference, 26.1 percentage points for vedoliz umab every 8 weeks vs. placebo [95% CI, 14.9 to 37.2; P<0.001] and 29.1 percentage points for vedolizumab every 4 weeks vs. placebo [95% CI, 17.9 to 40.4; P<0.001]). The frequency of adverse events was similar in the vedolizumab and placebo groups. Conclusions Vedolizumab was more effective than placebo as induction and maintenance therapy for ulcerative colitis.

TL;DR: Vedolizumab-treated patients with active Crohn's disease were more likely than patients receiving placebo to have a remission, but not a CDAI-100 response, at week 6; patients with a response to induction therapy who continued to receive vedolIZumab (rather than switching to placebo) were morelikely to be in remission at week 52.
Abstract: BackgroundUstekinumab, a monoclonal antibody to the p40 subunit of interleukin-12 and interleukin-23, was evaluated as an intravenous induction therapy in two populations with moderately to severely active Crohn’s disease. Ustekinumab was also evaluated as subcutaneous maintenance therapy. MethodsWe randomly assigned patients to receive a single intravenous dose of ustekinumab (either 130 mg or approximately 6 mg per kilogram of body weight) or placebo in two induction trials. The UNITI-1 trial included 741 patients who met the criteria for primary or secondary nonresponse to tumor necrosis factor (TNF) antagonists or had unacceptable side effects. The UNITI-2 trial included 628 patients in whom conventional therapy failed or unacceptable side effects occurred. Patients who completed these induction trials then participated in IM-UNITI, in which the 397 patients who had a response to ustekinumab were randomly assigned to receive subcutaneous maintenance injections of 90 mg of ustekinumab (either every 8 w...
