- Number of Randomized Participants Achieving Clinical Remission at Week 56 - Non-Responder Imputation (NRI) [ Time Frame: Week 56 ] [ Designated as safety issue: No ]Clinical remission is defined as CDAI score <150. CDAI evaluates 8 Crohn's−related variables during a 1−week assessment period, yielding a composite score >/= 0 and without upper limit. The range of scores during Study NCT00055497 and the lead-in study (NCT00055523) was 0 to 633. A lower score indicates less severe Crohn's disease activity.

- Change in Inflammatory Bowel Disease Questionnaire (IBDQ) Scores - LOCF [ Time Frame: Change from Baseline of lead-in study to Week 24 and Week 56 ] [ Designated as safety issue: No ]IBDQ is a validated disease−specific instrument that assesses the impact of IBD on patient quality of life during a 2−week recall period. It has 32 questions about bowel function and related symptoms, and their social and emotional impact. For each question, participants selected 1 of 7 responses, where 1=poor quality of life (e.g., feeling of fatigue "all of the time") and 7=good quality on the item (e.g., feeling of fatigue "none of the time"). IBDQ scores range from 32 to 224. Higher scores indicate better quality of life, and increases in IBDQ indicate improved overall quality of life.

Detailed Description:
Study NCT00055497 was designed to evaluate the efficacy and safety of adalimumab in the maintenance of clinical remission in patients with Crohn's disease (CD). The study consisted of 2 phases: 1. the first year phase lasting until Week 56 and consisting of a randomized, double-blind (DB), placebo-controlled portion (NCT00055497) and of a concomitant open label (OL) portion, and 2. a long-term extension phase (NCT01070303) that lasted 264 additional weeks (Week 56 to Week 320).
Potential participants were screened at the time of enrollment in the lead-in, induction therapy study (NCT00055523). Participants who completed the lead-in study, NCT00055523, were eligible to participate in the rollover study, NCT00055497.
In Study NCT00055497, all participants received 40 mg of adalimumab subcutaneously (SC) at Baseline (Week 0) and Week 2 of Study NCT00055497. Baseline of Study NCT00055497 is synonymous with NCT00055523 Week 4. At Week 4 of Study NCT00055497, participants were randomized based on their clinical remission status at Baseline and Week 4 of Study NCT00055497. Participants who demonstrated clinical remission (defined as a Crohn's Disease Activity Index [CDAI] score < 150 points) at Baseline of Study NCT00055497 and who remained in clinical remission at Week 4 of Study NCT00055497 (those participants constituted the randomized analysis set) were randomized to receive 1 of 3 blinded treatments: adalimumab 40 mg every other week (eow), adalimumab 40 mg every week (ew), or placebo. Participants who did not demonstrate clinical remission at Baseline of Study NCT00055497, or who were no longer in clinical remission at Week 4 of Study NCT00055497 were assigned to receive OL adalimumab 40 mg eow; those participants constituted the OL analysis set. At any time during Study NCT00055497, participants receiving OL adalimumab 40 mg SC eow who developed a flare or were non-responders during OL treatment could have had his/her dose increased to 40 mg SC weekly. Participants who were documented as having completed Week 56 are counted in the study completion total.
After 1 year (Week 56), participants who met eligibility criteria for the long-term extension phase (NCT01070303) were switched to OL adalimumab 40 mg subcutaneous (SC) eow, and participants previously in the OL treatment group of Study NCT00055497 continued on their previous OL adalimumab dose (adalimumab 40 mg SC eow or every week).
