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.

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 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.

Time frame: Week 26

Population: Modified full analysis set (mFAS), defined as all randomized participants who received at least 1 dose of investigational product (ie, active or placebo study medication) in this study and who were randomized into 1 of the tofacitinib (CP-690,550) dose groups in Study A3921083.

Kaplan-Meier Estimate of the Rate of Time to Relapse

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.
