- Primary Outcome Measures
Name Time Method Percentage of Participants in Clinical Remission (as Defined by a Crohn's Disease Activity Index [CDAI] Score of Less Than [<] 150 Points) at Week 8 Week 8 Clinical remission was a CDAI \< 150 points. CDAI is a composite index consisting of a weighted scoring of 8 disease variables: number of liquid or very soft stools, extent of abdominal pain, general well-being, occurrence of extra-intestinal 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.
The 15 mg BID treatment group was closed to further enrolment early on in the study by Protocol Amendment 5 after only 16 participants were enrolled into this group. Therefore, the efficacy analysis was not performed for this group because the results may be difficult to interpret due to the small sample size.
- Secondary Outcome Measures
Name Time Method EQ-5D Visual Analogue Scale (VAS) Scores at Baseline and Week 8/ET Visit Baseline, Week 8/ET visit EQ-5D 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.

IBDQ consists of 32 items, each item score ranged from 1 (worst possible response) to 7 (best possible response). 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.
Short Form 36 Health Survey (SF-36) Component and Domain Scores at Baseline and Week 8/ET Visit Baseline, Week 8/ET visit 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 SF-36 version 2 and SF-36 health domain scales and component summary measures have means of 50 and standard deviations of 10. Higher scores indicate better health-related QOL.
Change From Baseline IBDQ Total Score and Domain Scores (Bowel Function, Emotional Status, Systemic Symptoms, and Social Function) at Week 8/ET Visit Using Analysis of Covariance (ANCOVA) Baseline, Week 8/ET visit IBDQ is a validated PRO instrument for measuring QOL in IBD consisting of 32 items scored from 1 (worst response) to 7 (best response). 32 items are grouped into 4 domains scored as follows: bowel symptoms 10 - 70; systemic symptoms 5 - 35; emotional function 12 - 84; social function 5 - 35. For each domain, higher score indicates better QOL. Total score is the sum of each item score, \& ranged from 32 to 224 with a higher score indicating better QOL. Positive change in total score indicated improvement in QOL.
Adjusted means were derived from an ANCOVA model with baseline value as covariate, treatment group \& prior use of anti-tumor necrosis factor (TNF) alpha (α) treatments as factors.
The 15 mg BID treatment group was closed to further enrolment early in the study by Protocol Amendment 5 after only 16 participants were enrolled in this group. Therefore, the efficacy analysis was not performed for this group as the results may be difficult to interpret due to the small sample size.Percentage of Participants With a Response to the Patient-Reported Treatment Impact Assessment (PRTI) at Week 8/ET Visit by Category Week 8/ET visit The IBD Patient Reported Treatment Impact Modified (PRTI) 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 re-use 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.
Percentage of Participants Achieving Clinical Response-100 (as Defined by a Decrease in CDAI Score of at Least 100 Points From Baseline) at Weeks 2, 4, and 8 Baseline, Weeks 2, 4, and 8 Clinical response-100 was 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 or very soft stools, extent of abdominal pain, general well-being, occurrence of extra-intestinal 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.

Therefore, the efficacy analysis was not performed for this group because the results may be difficult to interpret due to the small sample size.C-Reactive Protein (CRP) Serum Concentrations at Weeks 2, 4, and 8 Weeks 2, 4, and 8 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.
Calprotectin Fecal Concentrations at Weeks 2, 4, and 8 Weeks 2, 4, and 8 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.
Tofacitinib Plasma Concentrations From 0 to 2 Hours Post Dose on Day 1 and at Week 8/Early Termination (ET) Visit Pre-dose, 20 minutes, 40 minutes, 1 hour, and 2 to 3 hours post-dose on Day 1 and Week 8/ET visit Plasma samples were collected from participants for the determination of tofacitinib concentrations. Only samples from tofacitinib-treated participants were subsequently analyzed. Plasma concentration data are summarized by nominal sample collection times specified in the protocol, and actual sample collection times may be different.
Percentage of Participants With an IBDQ Total Score of Greater Than or Equal to (≥) 170 at Week 8/ET Visit Week 8/ET visit The IBDQ is a psychometrically validated PRO instrument for measuring disease-specific 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 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.

CDAI scores range from 0 to approximately 600 points, higher score indicates higher disease activity.
Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score and Domain Scores (Bowel Function, Emotional Status, Systemic Symptoms, and Social Function) at Baseline and Week 8/ET Visit Baseline, Week 8/ET visit 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.
Change From Baseline EQ-5D Utility Scores at Week 8/ET Visit Using ANCOVA Baseline, Week 8/ET visit EQ-5D is a participant rated questionnaire to assess health-related QoL via a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain \& discomfort, anxiety \& depression; 1 = better health state (no problems); 3 = worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain. Score is transformed to a total score ranging from -0.594 to 1.000; higher score indicates better health state. Adjusted means were derived from the ANCOVA model with baseline value as a covariate, treatment group \& prior use of anti-TNFα treatments as factors.
