About this study

This was a Phase 2/3, multicenter, randomized, double-blind (DB), placebo-controlled, two-arm, efficacy, safety, and pharmacokinetic study designed to demonstrate the effectiveness of adalimumab in Japanese patients with moderate to severe Crohn's Disease (CD).

All participants who had completed Study M04-729 (NCT00445939), the lead-in adalimumab induction therapy study, were eligible for this study. Participants who rolled over into this study received either DB treatment (adalimumab or placebo) or open-label (OL) treatment with adalimumab.

Crohn's Disease Activity Index (CDAI) was used to determine participants who were responders and participants who were in clinical remission. CDAI documents number of soft stools, abdominal pain, general well-being, presence of 6 signs (arthritis/arthralgia; iritis/uveitis; erythema nodosum/pyoderma gangrenosum/aphthous stomatitis; fissure, abscess, anal fistula; other cutaneous fistula; fever over 100 degrees), taking medication for diarrhea, abdominal mass, hematocrit, and weight loss during a 1-week assessment period. It yields a total score >= 0 and without upper limit. Baseline scores in the study ranged from 221 to 448. Low score=less severe CD activity. Decrease in score indicates improvement.

Clinical remission is a CDAI score < 150.

Clinical response-70 (CR-70) = decrease in CDAI ≥ 70 points from lead-in study Baseline score.

Clinical response-100 (CR-100) = decrease in CDAI ≥ 100 points from lead-in study Baseline score.

Participants who had CR-70 response at Week 4 of the induction study were randomized into 1 of 2 treatment groups (double-blind adalimumab 40 mg every other week or adalimumab placebo every other week) using 2 stratification factors - CDAI category (CDAI less than 150 and CDAI 150 or higher) and presence/absence of fistula at Week 0 of this study. The double-blind treatment was to last from Week 0 to Week 52. Any time at or after Week 4 of this study, if a participant's disease flared (defined as a recurrence of very active disease, specifically an increase in CDAI when compared to Week 0 in this study of ≥ 70 points and a CDAI above 220) during the double-blind treatment period, the participant was allowed to move to OL treatment. At Week 52, all participants still receiving DB treatment were to be moved to open-label treatment and could continue in the study until adalimumab is approved for commercial use in Japan.

Participants who did not respond by Week 4 in the induction study and participants who had disease flare during DB treatment of this study entered OL treatment and received adalimumab 40 mg every other week. At or after Week 4 of this study, if a participant in the open-label treatment group had a disease flare or if the participant was still not responding to treatment, the participant was allowed to dose escalate to adalimumab 80 mg every other week. Participants who entered open-label treatment were to be allowed to continue on open-label adalimumab until adalimumab is approved for commercial use in Japan.

The study is complete. Results of this study are reported for endpoints at Week 52 (end of the DB treatment period) for subjects who received DB treatment (adalimumab or placebo) or OL adalimumab treatment and for endpoints at Week 148 for all subjects who received at least one dose of adalimumab in this study.

    The International Organization for the Study of Inflammatory Bowel Disease (IOIBD) score is an indicator of the activity of Crohn's disease. It measures absence (score of 0) or presence (score of 1) of abdominal pain, diarrhea or bloody stools more than 6 times per day, anal lesion, anal fistula, other complication, abdominal mass, weight loss, fever above 38 degrees Centigrade, abdominal tenderness, and blood pigment below 10 g/dL.

    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 item, participants select 1 of 7 responses. 1=poor quality of life (e.g., feeling of fatigue "all of the time") and 7=good quality (e.g., feeling of fatigue "none of the time"). Scoring range = 32 to 224. Higher scores indicate better quality of life; increases in IBDQ = improved overall quality of life.

    The Short-Form-36 (SF-36) Health Survey is a comprehensive quality of life scale. An increase in SF-36 score indicates alleviation of the disease and a decrease in score indicates aggravation of disease. The physical component reflects activity level, activity limitations, pain, and rating of one's health. Score on the physical component ranges from 0 (Poorest Health) to 100 (Best Health).

The mental component reflects energy/vitality, social functioning, limitations, and ratings of one's mental health. Score on mental component ranges from 0 (worst score) to 100 (best score).
