A Open-Label Study Of CP-690,550 As Long-Term Therapy (48 Weeks) In Subjects With Crohn's Disease

CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid or very soft stools, intensity 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 points, higher score indicates higher disease activity. Clinical remission was defined as a CDAI score of less than (<) 150. Sustained clinical remission was defined as being in clinical remission (CDAI score <150) at both Week 24 and Week 48. 95 percent (%) Clopper-Pearson exact confidence interval reported for the proportions. n = number of participants with non-missing data.

Sustained clinical remission was defined as being in clinical remission (CDAI score <150) at both Week 24 and Week 48. Clinical response was defined as a CDAI score reduction of at least 100 points from the A3921083 study baseline value. 95% Clopper-Pearson exact confidence interval reported for the proportions. n = number of participants with non-missing data.

Relapse was defined as an increase in CDAI of more than (>) 100 points from the baseline and an absolute CDAI score of >220 points. CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid or very soft stools, intensity 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 points, higher score indicates higher disease activity. Data presented are rates estimated from Kaplan-Meier curves.

n = number of participants remaining at risk.

Steroid-free clinical remission at Week 48 was a CDAI <150 points in participants who were steroid-free at Week 48.

Use of corticosteroids (yes or no) was recorded at baseline and throughout the study. Percentage of participants taking corticosteriod at each visit was reported.

There was a single study treatment dose adjustment allowed, at the discretion of the Investigator, from 5 mg BID to 10 mg BID or from 10 mg BID to 5 mg BID, after the initial 8 weeks of fixed open label treatment and for the remaining treatment period of 40 weeks. Percentage of participants whose study treatment were switched from 5 mg BID to 10 mg BID or 10 mg BID to 5 mg BID after initial assignment was reported.

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. n = number of participants with non-missing data.

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. n = number of participants with non-missing data.

The IBDQ is a psychometrically validated patient reported outcome (PRO) instrument for measuring disease-specific quality of life (QoL) in participants with inflammatory bowel disease (IBD). IBDQ consists of 32 items, each item score ranged from 1 (worst possible response) to 7 (best possible response). The 32 items are grouped into 4 domains: bowel function, emotional status, systemic symptoms and social function. The 4 domains are scored as follows: bowel symptoms 10 to 70; systemic symptoms 5 to 35; emotional function 12 to 84; social function 5 to 35. For each domain, a higher score indicates better QoL. Total score is the sum of each item score, and ranged from 32 to 224 with a higher score indicating a better QoL. Positive change in total score indicated improvement in QoL. n = number of participants with non-missing data.

A score ≥170 corresponds to clinical remission. 95% Clopper-Pearson exact confidence interval reported for the proportions.

The IBD PRTI modified questionnaire comprises 3 individual questions administered to the participant: participant satisfaction with study treatment; participant preference for study drug over prior treatment (this question on participant preference for study drug is prefaced by a simple question of previous treatment/s for IBD received in order to place the preference question into context) and participant willingness to reuse the study treatment again. Each of these questions (except the question on previous treatment, which is informational only) is scored on a 5 point Likert scale. PSA = Patient Satisfaction Assessment; PPTA = Patient Previous Treatment Assessment; PPA = Patient Preference Assessment; PWA = Patient Willingness Assessment.

The component and domain scores were scored using the United States (US) 1998 general population norms. The resulting norm-based T scores for both the SF36 version 2 and SF36 health domain scales and component summary measures have means of 50 and standard deviations of 10. Higher scores indicate better health-related QoL. n = number of participants with non-missing data.

EQ5D is a participant rated questionnaire to assess health-related QoL in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, selfcare, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range from 0.594 to 1.000; a higher score indicates a better health state. n = number of participants with non-missing data.

EQ5D is a participant rated questionnaire to assess health-related QoL in terms of a single index value. The VAS component rates current health state on a scale from 0 millimeters (mm) (worst imaginable health state) to 100 mm (best imaginable health state); higher scores indicate a better health state. n = number of participants with non-missing data.

The number of participants hospitalized due to Crohn's disease were recorded at every study visit.

The length of hospitalizations due to Crohn's disease were recorded at every study visit.
