Primary Outcome Measures:
  • Percentage of Participants With Clinical Response [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    Clinical response was defined as a decrease from baseline in Mayo score of at least 3 points and at least 30 percent, with accompanying decrease in subscore for rectal bleeding of at least 1 point or absolute subscore for rectal bleeding of 0 or 1. Mayo score: instrument designed to measure disease activity of ulcerative colitis. Total score range: 0 to 12; higher score=more severe disease. It consisted of 4 subscores: stool frequency, rectal bleeding, findings of flexible proctosigmoidoscopy and physician global assessment, each ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe).


Secondary Outcome Measures:
  • Percentage of Participants With Clinical Remission [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    Clinical remission was defined as a total Mayo score of 2 points or lower, with no individual subscore exceeding 1 point. Mayo score:instrument designed to measure disease activity of ulcerative colitis. Total score range: 0 to 12; higher score=more severe disease. It consisted of 4 subscores: stool frequency, rectal bleeding, findings of flexible proctosigmoidoscopy and physician global assessment, each ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe).

  • Percentage of Participants With Endoscopic Response [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    Endoscopic response was defined as decrease from baseline in the findings of the flexible proctosigmoidoscopy subscore of the Mayo score at least 1 point. Mayo score: instrument designed to measure disease activity of ulcerative colitis. Total score range: 0 to 12; higher score=more severe disease. It consisted of 4 subscores: stool frequency, rectal bleeding, findings of flexible proctosigmoidoscopy and physician global assessment, each ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe).

  • Percentage of Participants With Endoscopic Remission [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    Endoscopic remission was defined as the findings of flexible proctosigmoidoscopy subscore of the Mayo score equals 0. Mayo score: instrument designed to measure disease activity of ulcerative colitis. Total score range: 0 to 12; higher score=more severe disease. It consisted of 4 subscores: stool frequency, rectal bleeding, findings of flexible proctosigmoidoscopy and physician global assessment, each ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe).

  • Change From Baseline in Partial Mayo Score at Week 2, 4, 8 and 12 [ Time Frame: Baseline, Week 2, 4, 8, 12 ] [ Designated as safety issue: No ]
    Partial Mayo score was ranged from 0 (normal or inactive disease) to 9 (severe disease) and calculated as the sum of 3 subscores: stool frequency, rectal bleeding and physician's global assessment, each ranged from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe).

  • Change From Baseline in Total Inflammatory Bowel Disease Questionnaire (IBDQ) Score at Week 8 [ Time Frame: Baseline, Week 8 ] [ Designated as safety issue: No ]
    IBDQ: Psychometrically validated patient reported outcome (PRO) instrument for measuring disease-specific quality of life (QOL) in participants with IBD. IBDQ consists of 32 items, each item score ranged from 1 (worst possible response) to 7 (best possible response). Total score is sum of each item score, ranged from 32 to 224 with higher score indicates better QOL. Positive change in total score indicated improvement in QOL.

  • Change From Baseline in Level of C-Reactive Protein (CRP) at Week 4 and 8 [ Time Frame: Baseline, Week 4, 8 ] [ Designated as safety issue: No ]
    The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

  • Change From Baseline in Level of Fecal Calprotectin at Week 2, 4, 8 and 12 [ Time Frame: Baseline, Week 2, 4, 8, 12 ] [ Designated as safety issue: No ]
    Fecal calprotectin is an inflammatory marker for the gastrointestinal tract and considered as a measurement of neutrophil migration to the gastrointestinal tract. Higher values indicate more serious inflammation.

  • Plasma Concentration of CP-690,550 [ Time Frame: 0.25, 0.5, 1, 2 hours post-dose on Day 1, 0 (pre-dose) and 1 hour post-dose on Week 2, Week 4, 0 (pre-dose), 0.25, 0.5, 1, 2 hours post-dose on Week 8 ] [ Designated as safety issue: No ]
    Summary statistics were calculated for each dose group using the nominal collection times and by setting concentration values below the lower limit of quantification (LLOQ) (LLOQ=0.1 nanogram per milliliter [ng/mL]) to zero.
