Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Clinical Response-100 (as Defined by a Decrease in Crohn's Disease Activity Index [CDAI] Score of at Least 100 Points From Baseline) or Clinical Remission (CDAI Score Less Than [<]150) at Week 26Week 26

Clinical response-100 was defined as a reduction in CDAI score of at least 100 points from baseline of the parent A3921083 study. Clinical remission was a CDAI score \<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 anti-diarrheal 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.

Secondary Outcome Measures
NameTimeMethod

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.

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 wellbeing, 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

Change From Baseline in CDAI Score by WeekWeeks 4, 8, 12, 20 and 26

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 wellbeing, 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

Kaplan-Meier Estimate of the Rate of Time to RelapseWeeks 4, 8 12, 20 and 26

Time to relapse was defined as increase in CDAI of more than (\>)100 points from the maintenance phase baseline and a CDAI score of \>220 points, or an increase to or above the baseline CDAI score in A3921083. 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 wellbeing, 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.

Percentage of Participants Achieving a Steroid-Free Clinical Remission at Week 26 of the Maintenance Phase - Among Participants on Steroids at A3921084 BaselineWeek 26

Clinical remission was a CDAI \<150 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 wellbeing, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body eight. CDAI scores range from 0 to approximately 600 points, higher score indicates higher disease activity.

C-Reactive Protein (CRP) by WeekBaseline and Weeks 4, 8, 12, 20 and 26

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 CRP by WeekWeeks 4, 8, 12, 20 and 26

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.

Fecal Calprotectin by WeekBaseline and Weeks 8, 12 and 26

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.

Change From Baseline in Fecal Calprotectin by WeekWeeks 8, 12 and 26

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 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.
