The purpose of this study is to compare the safety and effectiveness of dosing mesalazine 800 mg tablets (Asacol®) at 2.4 g once daily versus divided doses three times daily in the maintenance of remission of ulcerative colitis.
- Multicentre, randomized, single-blind, comparator-controlled, parallel-armed study
- One year follow-up, or until relapse (whichever shorter)
- 40-60 UK centres
- Ulcerative colitis in remission (sigmoidoscopy score of 0 or 1 with no symptoms of active disease, with no treatment for active colitis) for at least 4 weeks, and for no more than 2 years
- Taking mesalazine or sulfasalazine prior to study entry
- Patients excluded if they have Crohn's disease, symptoms of active colitis, have used corticosteroids, ciclosporin or oral/enema mesalazine in the past 4 weeks, are intolerant to mesalazine or Asacol, are pregnant or lactating, or have known HIV, hepatic disease, renal impairment or other serious medical or psychiatric illness
- Sample size 250
- Gender: male or female
- Ethnicity: no restriction
- Age: over 18
Once daily group: Asacol® 2.4g daily given as three 800mg tablets orally qAM
Three times daily group: Asacol® 2.4g daily given as one 800mg tablet orally three times daily
Criteria for Evaluation:
Primary Outcome Variable: Relapse rate over 1 year in the intention to treat population, with the study powered to detect non-inferiority of the once-daily regimen.
Secondary Outcome Variables: assessment of superiority of the once-daily regimen, if non-inferiority is demonstrated; safety analysis; per protocol analysis of relapse rate; time course of relapse; medication compliance; changes in modified Baron sigmoidoscopy scores between trial entry and relapse/12 month; impact of various factors on relapse rate (time from last relapse at study entry, concomitant azathioprine or 6-mercaptopurine therapy; disease extent; disease duration; smoking status; age at diagnosis; previous dose of mesalazine; baseline calprotectin; baseline CRP level).
Allocation: Randomized, Control: Dose Comparison, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

The purpose of this study is to determine if taking Asacol once a day is as effective as taking Asacol twice or three times a day in keeping ulcerative colitis inactive, and to determine w...
We, the investigators at University of Washington, plan on evaluating the effect of open label Asacol at a dose of 4.8 grams/day divided BID (twice per day) or TID (three times per day) on...
The purpose of this study was to demonstrate that mesalazine 4g orally per day once daily (QD) is non-inferior to the reference regimen, mesalazine 4g per day in two divided doses (BID) (2...
Asacol™ 4.8 g/day (800 mg tablets) is statistically significant more effective to induce clinical and endoscopic remission after 6 weeks of treatment compared to placebo in subjects with...
The overall objective of this study is to assess the safety and efficacy of high dose and low dose Asacol administered as 400 mg delayed-release tablets given every 12 hours for 6 weeks to...
Fish oil (FO) and mesalazine have well-known anti-inflammatory and antioxidant effects; on the other hand, information related to combined intrarectal administration of FO and mesalazine is limited. T...
Tacrolimus is effective for refractory ulcerative colitis in adults, while data for children is sparse. We aimed to evaluate the effectiveness and safety of tacrolimus for induction and maintenance th...
There is substantial compelling clinical evidence implicating certain dietary components in the development and clinical course of progression in ulcerative colitis (UC). The current study aimed to as...
Systemic molecular mediators of inflammation differentiate between Crohn's disease and ulcerative colitis, implicating threshold levels of IL-10 and relative ratios of pro-inflammatory cytokines in therapy.
Faecal diversion is associated with improvements in Crohn's disease but not ulcerative colitis, indicating differing mechanisms mediate the diseases. This study aimed to investigate levels of systemic...
There are limited data on the most cost-effective sequencing of biologics for ulcerative colitis (UC).
Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS.
Inflammation of the COLON that is predominantly confined to the MUCOSA. Its major symptoms include DIARRHEA, rectal BLEEDING, the passage of MUCUS, and ABDOMINAL PAIN.
An acute form of MEGACOLON, severe pathological dilatation of the COLON. It is associated with clinical conditions such as ULCERATIVE COLITIS; CROHN DISEASE; AMEBIC DYSENTERY; or CLOSTRIDIUM ENTEROCOLITIS.
A humanized monoclonal antibody that binds specifically to TNF-ALPHA and blocks its interaction with endogenous TNF RECEPTORS to modulate INFLAMMATION. It is used in the treatment of RHEUMATOID ARTHRITIS; PSORIATIC ARTHRITIS; CROHN'S DISEASE and ULCERATIVE COLITIS.
A surgical procedure involving the excision of the COLON and RECTUM and the formation of an ILEOANAL RESERVOIR (pouch). In patients with intestinal diseases, such as ulcerative colitis, this procedure avoids the need for an OSTOMY by allowing for transanal defecation.
Crohn's Disease (CD)
Crohn’s disease (CD) is a long-term condition that causes inflammation of the lining of the digestive system. Inflammation can affect any part of the digestive system, from the mouth to the back passage, but most commonly occurs in the last s...
