Low dose oral pH modified release budesonide for maintenance of steroid induced remission in Crohn's disease. The Budesonide Study Group.

ABSTRACT: BACKGROUND: The relapse rate after steroid induced remission in Crohn's disease is high. AIMS: To test whether oral pH modified release budesonide (3 x 1 mg/day) reduces the relapse rate and to identify patient subgroups with an increased risk of relapse. METHODS: In a multicentre, randomised, double blind study, 179 patients with steroid induced remission of Crohn's disease received either 3 x 1 mg budesonide (n = 84) or placebo (n = 95) for one year. The primary study aim was the maintenance of remission of Crohn's disease for one year. RESULTS: Patient characteristics at study entry were similar for both groups. The relapse rate was 67% (56/84) in the budesonide group and 65% (62/95) in the placebo group. The relapse curves in both groups were similar. The mean time to relapse was 93.5 days in the budesonide group and 67.0 days in the placebo group. No prognostic factors allowing prediction of an increased risk for relapse or definition of patient subgroups who derived benefit from low dose budesonide were found. Drug related side effects were mild and no different between the budesonide and the placebo group. CONCLUSION: Oral pH modified release budesonide at a dose of 3 x 1 mg/day is not effective for maintaining steroid induced remission in Crohn's disease.

Project description:BackgroundBudesonide is an oral glucocorticoid designed for the treatment of inflammatory bowel disease (IBD) that may reduce systemic adverse events (AEs). This review examined the efficacy and safety of budesonide for the induction and maintenance of clinical remission in Crohn's disease (CD).MethodsMEDLINE, EMBASE, other electronic databases, reference lists and conference proceedings were searched to November 2017 to identify randomized controlled trials of budesonide. Outcomes were the induction and maintenance of remission at eight weeks and one year, respectively, as well as corticosteroid-related AEs and abnormal adrenocorticotropic hormone (ACTH) tests. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were estimated using random effects models.ResultsThirteen induction and 10 maintenance trials were included. Budesonide 9 mg/day was more effective than placebo (RR 1.93; 95% CI, 1.37-2.73; GRADE: moderate) but less effective than conventional steroids (RR 0.85; 95% CI, 0.75-0.97; GRADE: moderate) to induce remission. Corticosteroid-related AEs occurred less often with induction doses of budesonide than steroids (RR 0.64; 95% CI, 0.54-0.76; GRADE: moderate); budesonide did not increase AEs relative to placebo (RR 0.97; 95% CI, 0.76-1.23; GRADE: moderate). Budesonide 6 mg/day was not different from placebo for maintaining remission (RR 1.13; 95% CI, 0.94-1.35; GRADE: moderate). Both induction (GRADE: low for 3 mg/day, moderate for 9 mg/day) and maintenance budesonide treatment (GRADE: very low for 3 mg/day, low for 6 mg/day) increased the risk of an abnormal ACTH test compared with placebo, but less than conventional steroids (GRADE: very low for both induction and maintenance).ConclusionFor induction of clinical remission, budesonide was more effective than placebo, but less effective than conventional steroids. Budesonide was not effective for the maintenance of remission. Budesonide was safer than conventional steroids, but the long-term effects on the adrenal axis and bone health remain unknown.

Project description:ObjectiveThis 1-year study aimed to assess low-dose budesonide therapy for maintenance of clinical remission in patients with collagenous colitis.DesignA prospective, randomised, placebo-controlled study beginning with an 8-week open-label induction phase in which patients with histologically confirmed active collagenous colitis received budesonide (Budenofalk, 9 mg/day initially, tapered to 4.5 mg/day), after which 92 patients in clinical remission were randomised to budesonide (mean dose 4.5 mg/day; Budenofalk 3 mg capsules, two or one capsule on alternate days) or placebo in a 12-month double-blind phase with 6 months treatment-free follow-up. Primary endpoint was clinical remission throughout the double-blind phase.ResultsClinical remission during open-label treatment was achieved by 84.5% (93/110 patients). The median time to remission was 10.5 days (95% CI (9.0 to 14.0 days)). The maintenance of clinical remission at 1 year was achieved by 61.4% (27/44 patients) in the budesonide group versus 16.7% (8/48 patients) receiving placebo (treatment difference 44.5% in favour of budesonide; 95% CI (26.9% to 62.7%), p<0.001). Health-related quality of life was maintained during the 12-month double-blind phase in budesonide-treated patients. During treatment-free follow-up, 82.1% (23/28 patients) formerly receiving budesonide relapsed after study drug discontinuation. Low-dose budesonide over 1 year resulted in few suspected adverse drug reactions (7/44 patients), all non-serious.ConclusionsBudesonide at a mean dose of 4.5 mg/day maintained clinical remission for at least 1 year in the majority of patients with collagenous colitis and preserved health-related quality of life without safety concerns. Treatment extension with low-dose budesonide beyond 1 year may be beneficial given the high relapse rate after budesonide discontinuation.Trial registration numbershttp://www.clinicaltrials.gov (NCT01278082) and http://www.clinicaltrialsregister.eu (EudraCT: 2007-001315-31).

Project description:BackgroundCrohn's disease (CD) and multiple sclerosis (MS) share common pathogenic processes. Interferon (IFN) beta-1a is effective and generally well tolerated in patients with MS and has been shown to down-regulate the expression of interleukin-12, a cytokine that is thought to be involved in mucosal degeneration in CD. IFN beta-1a therefore offers promise as a treatment for CD.MethodsIn this multicentre, double-blind, placebo-controlled, phase II, dose-finding study, patients with steroid-induced clinical remissions of CD were randomized 1:1:1:1 to subcutaneous IFN beta-1a: 66 mcg three times weekly (tiw), 44 mcg tiw, 44 mcg twice weekly (biw), or matching placebo tiw with steroid tapering. The primary endpoint was the proportion of patients relapse-free at Week 26. Safety was also assessed.ResultsThis study was terminated early following a planned interim analysis at 26 weeks. Of the planned 192 patients, 67 were randomized to treatment: placebo (n = 16), or IFN beta-1a 44 mcg biw (n = 17), 44 mcg tiw (n = 16) or 66 mcg tiw (n = 18). In total, 20/67 patients (29.9%) completed 26 weeks and 7 patients (10.4%) completed 52 weeks. The proportion of patients who remained relapse-free at Week 26 did not differ significantly between the placebo group (5/16, 31%) and the IFN beta-1a 44 mcg biw (6/17, 35%; p = 0.497), 44 mcg tiw (7/16, 44%; p = 0.280) or 66 mcg tiw (2/18, 11%; p = 0.333) groups. There was little difference between treatment groups in secondary efficacy endpoints. IFN beta-1a was generally well tolerated at all doses. Adverse events (AEs) were generally mild or moderate in IFN beta-1a-treated patients, with the most common AEs (influenza-like symptoms, headache, injection-site reactions) being similar to those reported with IFN beta-1a in MS.ConclusionThere was no difference in efficacy between patients with CD receiving IFN beta-1a or placebo. However, these results should be considered in the context of the low patient numbers and high dropout rate. Overall, IFN beta-1a was generally well tolerated, with a safety profile that was consistent with previous experience in MS.Trial registrationClinicalTrials.gov NCT00304252.
