  Purpose

This study investigates safety and efficacy of CP-690,550 in adult patients with moderate to severe Crohn's disease. The study hypothesis is that at least one of the dose levels to be tested will be more effective than placebo (inactive drug).

Primary Outcome Measures:
  • Number of Participants With Clinical Response 70 at Week 4 [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Clinical response 70: defined as a reduction in Crohn's Disease Activity Index (CDAI) score from baseline of at least 70 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.


Secondary Outcome Measures:
  • Number of Participants With Clinical Response 70 at Week 1 and 2 [ Time Frame: Week 1, 2 ] [ Designated as safety issue: No ]
    Clinical response 70: defined as a reduction in CDAI score from baseline of at least 70 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.

  • Number of Participants Achieving Clinical Remission at Week 4 [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Clinical remission=CDAI at Week 4 less than (<) 150 points. CDAI is a composite index consisting of a weighted scoring of 8 disease variables:number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI score was based partly on entries (7 days before evaluation) from participant's Diary kept while on study. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.

  • Number of Participants With Clinical Response 100 at Week 4 [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Clinical response 100: defined as a reduction in CDAI score from baseline of at least 100 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.

  • Time to First Clinical Remission [ Time Frame: Week 1 through Week 4 ] [ Designated as safety issue: No ]
    Clinical remission=CDAI <150 points. CDAI is a composite index consisting of a weighted scoring of 8 disease variables:number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI score was based partly on entries (7 days before evaluation) from participant's Diary kept while on study. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.

  • Time to First Response 70 [ Time Frame: Week 1 through Week 4 ] [ Designated as safety issue: No ]
    Clinical response 70: defined as a reduction in CDAI score from baseline of at least 70 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600 , higher score indicates higher disease activity.

  • Time to First Response 100 [ Time Frame: Week 1 through Week 4 ] [ Designated as safety issue: No ]
    Clinical response 100: defined as a reduction in CDAI score from baseline of at least 100 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight. CDAI scores range from 0 to approximately 600, higher score indicates higher disease activity.
