Official Title: Multi Center Ulcerative Colitis Pediatric Pentasa Intervention Trial (MUPPIT). A Randomized, Single-blinded, Controlled, Parallel, Induction Therapy With Once vs. Twice Daily Dosing of Pentasa in Pedi

Brief Summary: The purpose of this study is to evaluate effectiveness of once daily dosing of Pentasa compared with twice daily in children with mild to moderate active ulcerative colitis.

Detailed Summary:

Several randomized controlled trials (RCTs) have affirmed the efficacy of 5-aminosalicylic acid (5-ASA) and sulfasalazine in the acute treatment of mild to moderate exacerbations, as well as in the maintenance of clinical remission. Initially, common practice was to prescribe 5-ASA in three divided doses. Slow release once daily mesalamine with Multi Matrix System (MMX) technology was shown to be effective in induction and maintenance of remission of adult ulcerative colitis (UC). Since transit time of the colon is much slower than the small-bowel, and since the active ingredient should act locally on the colon, less frequent dosing of the regular formulation may also provide sufficient colonic coverage. Indeed, two recent studies among adults with UC suggest that once daily dosing of mesalamine (Pentasa® and Salofalk®) may be as or more effective than twice daily dosing.

To date, most RCTs have been conducted among adult patients and efficacy in children has been extrapolated from these data. However, childhood inflammatory bowel disease (IBD) may not be similar to adult onset disease. The prevalence of extensive colitis proximal to the splenic flexure is doubled in pediatric-onset UC compared to adults and extensive disease is consistently associated with more severe phenotype. On the other hand, studies in children with IBD often show better response to therapy than in adults. Therefore, American and European regulating agencies encourage pediatric studies be conducted for all approved drug products. It has been found that less than 50% of children with IBD are adherent with treatment, a figure associated with the understanding of the disease which is generally lower than in adults. Therefore, the advantage of once daily dosing of 5-ASA over twice-daily may be greater in children compares with adults.

Current Primary Outcome: Difference in mean PUCAI score between the groups. [ Time Frame: At week 6 after initiation of therapy. ]

Original Primary Outcome: Same as current

Current Secondary Outcome: Treatment success defined as Complete response OR large partial response. [ Time Frame: At 3 and 6 weeks from initiation of therapy. ]

Complete response: A a PUCAI score <10 points AND a change of at least 10 points from baseline.

Small partial response: A a change in PUCAI score of at least 10 points from baseline AND a PUCAI score of ≥10 points.

Large partial response: A change in PUCAI score of at least 20 points from baseline AND a PUCAI score of ≥10 points.

Treatment Failure: A lack of improvement of at least 10 points from the baseline PUCAI score despite at least 3 weeks of treatment, or requirement of corticosteroids at any time.



Original Secondary Outcome: Same as current
