Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: A Double-Blind, Randomized, 6-Week, Parallel-Group Design Clinical Trial to Assess Safety and Efficacy of Asacol 4.8 g/Day (800 mg Tablet) Versus Asacol 2.4 g/Day (400 mg Tablet) for the Treatment of Moderately Active Ulcerative Colitis

Primary Outcome Measures:
  • Percentage of Treatment Success Patients at Week 6, ITT (Intent to Treat) Population [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    Treatment success defined as complete response (PGA score 0 and complete resolution of stool frequency, rectal bleeding, PFA (patient's functional assessment), normal sigmoidoscopy) or partial response (improvement from baseline PGA and improvement in 1 clinical assessment [stool frequency, rectal bleeding, PFA, sigmoidoscopy] and no worsening in any other clinical assessments)


Secondary Outcome Measures:
  • Change From Baseline in Ulcerative Colitis Disease Activity Index (UCDAI) at Week 6, ITT Population [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    UCDAI - sum of clinical assessment scores (stool frequency score [0=normal, 1=1-2 stools > normal/day, 2=3-4 stools > normal/day, 3=5 or more stools > normal/day], rectal bleeding score [0=no blood seen, 1=streaks of blood with stool less than half of the time, 2=obvious blood with stool most of the time, 3=blood alone passed and PGA score [0=quiescent disease, 1=mild, 2=moderate, 3=severe]) and sigmoidoscopy score [0=normal, 1=mild, 2=moderate, 3=severe]

  • Percentage of Participants Whose Rectal Bleeding & Sigmoidoscopy Score Both Improved From Baseline to Week 6, ITT Population [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    Rectal Bleeding - 0=no blood seen, 1=streaks of blood w/stool less than half of the time, 2=obvious blood w/stool most of the time, 3=blood alone passed Sigmoidoscopy Assessment Score - 0=normal (intact vascular pattern, no friability or granularity), 1=mild (erythema, diminished or absent vascular markings; mild granularity; friability), 2=moderate (marked erythema, granularity; absent vascular markings; bleeds with minimal trauma; no ulcerations) 3=severe (spontaneous bleeding, ulcerations)

  • Percentage of Patients Whose Sigmoidoscopy Score Improved From Baseline to Week 6, ITT Population [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    Sigmoidoscopy Assessment Score (0=normal intact vascular pattern, no friability or granularity, 1=mild erythema; diminished or absent vascular markings; mild granularity; friability, 2=moderate marked erythema, granularity; absent vascular markings; bleeds with minimal trauma; no ulcerations, 3=severe spontaneous bleeding, ulcerations)

  • Percentage of Patients With an Improvement in Stool Frequency, ITT Population, Week 6 [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    0=Normal stool frequency per day, 1=1-2 stools greater than normal per day, 2=3-4 stools greater than normal per day, 3=5 or more stools greater than normal per day

  • Percentage of Patients With Improvement in Rectal Bleeding, ITT Population, Week 6 [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    Rectal Bleeding (0=no blood seen, 1=streaks of blood with stool less than half of the time, 2=obvious blood with stool most of the time, 3=blood alone passed)

  • Percentage of Patients With Improvement in Patient's Functional Assessment (PFA), ITT Population, Week 6 [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    PFA - 0=generally well, 1=fair, 2=poor, 3=terrible

  • Percentage of Patients With Improvement in Physician Global Assessment (PGA)Score, ITT Population, Week 6 [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    PGA -Physician's Global Assessment - 0=quiescent disease (all parameters 0), 1=mild disease (parameters mostly 1's) 2=moderate (parameters mostly 2's), 3=severe (parameters mostly 3's) [parameters: combination of stool frequency, rectal bleeding, PFA & sigmoidoscopy findings] If scoring equal default to physician judgement.

  • Mean Change From Baseline in Total Inflammatory Bowel Disease Questionnaire (IBDQ) at Week 3, All Randomized Patients [ Time Frame: 3 Weeks ] [ Designated as safety issue: No ]
    IBDQ-32 questions divided into 4 categories: bowel, systemic, emotional and social. Each question graded with the following responses: 1-more than ever before, 2-extremely frequently, 3-very frequently, 4-moderate increase in frequency, 5-some increase in frequency, 6-slight increase in frequency or 7-not at all/normal; 1/worst thru 7/best. Scoring 32 - 224 - higher score better.

  • Mean Change From Baseline in Total Inflammatory Bowel Disease Questionnaire (IBDQ) at Week 6, All Randomized Patients [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    IBDQ-32 questions divided into 4 categories: bowel, systemic, emotional and social. Each question graded with the following responses: 1-more than ever before, 2-extremely frequently, 3-very frequently, 4-moderate increase in frequency, 5-some increase in frequency, 6-slight increase in frequency or 7-not at all/normal; 1/worst thru 7/best. Scoring 32-224 - higher score better.

  • Percentage of Patients With Moderate, Left-Sided Disease at Baseline Classified as Treatment Success at Week 6, All Randomized Patients [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    Treatment success defined as complete response (PGA score 0 and complete resolution of stool frequency, rectal bleeding, PFA (patient's functional assessment), normal sigmoidoscopy) or partial response (improvement from baseline PGA and improvement in 1 clinical assessment [stool frequency, rectal bleeding, PFA, sigmoidoscopy] and no worsening in any other clinical assessments)

  • Percentage of Treatment Success Patients at Week 3, ITT Population [ Time Frame: 3 Weeks ] [ Designated as safety issue: No ]
    Treatment success defined as complete response (PGA score 0 and complete resolution of stool frequency, rectal bleeding, PFA (patient's functional assessment), normal sigmoidoscopy) or partial response (improvement from baseline PGA and improvement in 1 clinical assessment [stool frequency, rectal bleeding, PFA, sigmoidoscopy] and no worsening in any other clinical assessments)
