Drug Information available for: Adalimumab

Arm Intervention/treatment
Experimental: Any adalimumab
Adalimumab was administered via subcutaneous injection. Dosage was based on body weight and clinical status, and ranged from 10, 20, or 40 mg every other week to 20 or 40 mg every week.
Biological: Adalimumab
Participants who enrolled into the study from blinded therapy in Study M06-806 received open-label (OL) therapy at a dose dependent on their body weight. Participants weighing ≥ 40 kg received 40 mg of adalimumab every other week (eow), and those who weighed < 40 kg received 20 mg of adalimumab eow. Starting at Week 8, participants who had a disease flare may have been switched to every week (ew) treatment at the same dose of adalimumab received while on eow treatment. Participants who enrolled from OL therapy in Study M06-806 continued to receive the same dose they were receiving (i.e., 40 mg ew or 20 mg ew) at the Week 52 visit of Study M06-806. Adalimumab dose could have been decreased to the next lower treatment level for those with body weight changes. Participants who responded to treatment may have also had their dosage frequency decreased from ew to eow dosing, as well as a decrease in dosage.

Primary Outcome Measures :
  1. Number of Participants Who Achieved Pediatric Crohn's Disease Activity Index (PCDAI) Clinical Remission Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408 ]
    Pediatric Crohn's Disease Activity Index (PCDAI) is an index used to measure disease activity of pediatric patients with Crohn's disease assessing abdominal pain, stool frequency, patient functioning, hematocrit, erythrocyte sedimentation rate, albumin, weight, height, abdomen, perirectal disease, and extraintestinal manifestations. It ranges from 0 to 100; higher scores indicate more active disease. Clinical remission was defined as PCDAI ≤ 10.

  2. Number of Participants With Clinical Response as Defined by Pediatric Crohn's Disease Activity Index (PCDAI) Score Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408 ]
    Pediatric Crohn's Disease Activity Index (PCDAI) is an index used to measure disease activity of pediatric patients with Crohn's disease assessing abdominal pain, stool frequency, patient functioning, hematocrit, erythrocyte sedimentation rate, albumin, weight, height, abdomen, perirectal disease, and extraintestinal manifestations. It ranges from 0 to 100; higher scores indicate more active disease. The baseline PCDAI value was defined as the last non-missing value on or before the date of the first dose of study drug during Study M06-806. Clinical response was defined as a PCDAI ≥ 15 points lower than the Study M06-806 baseline PCDAI value.


Secondary Outcome Measures :
  1. Number of Participants Who Were in Crohn's Disease Activity Index (CDAI) Clinical Remission Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408 ]
    The CDAI includes 8 variables encompassing both subject-reported (symptoms, general well-being) and objective (medication usage, laboratory variables, presence of abdominal mass or complications, and weight) variables. For symptoms scores, participants kept track of daily symptoms on a diary card, and the daily symptom scores were summed for the week. Each item in the CDAI is assigned a specific weight, and the weighted values of the items are totaled to produce the CDAI score. Higher CDAI scores indicate greater disease activity; 0 is the lower limit with no set upper limit. The scale for the score is as follows: < 150 to indicate remission, 150 - 219 to define mildly active disease, 220 - 450 to define moderately active disease, and > 450 to define severely active disease. A CDAI was calculated at each visit for participants who were age 13 or older at Study M06-806 entry. The Study M06-806 Week 52 visit served as the baseline visit for this study.

  2. Number of Participants Who Were in Crohn's Disease Activity Index (CDAI) Clinical Response Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408 ]
    The CDAI includes 8 variables: subject-reported (symptoms, general well-being) and objective (medication usage, laboratory variables, presence of abdominal mass or complications, and weight). Participants kept track of symptoms on a diary card, and scores were summed for the week. Each item is assigned a specific weight, and the weighted values of the items are totaled to produce the CDAI score. Higher CDAI scores indicate greater disease activity; 0 is the lower limit with no set upper limit. Scale: < 150 (remission), 150 - 219 (mildly active disease), 220 - 450 (moderately active disease), and > 450 (severely active disease). A CDAI was calculated at each visit for participants ≥ 13 yrs old at M06-806 entry. Clinical response was defined as a decrease from M06-806 Baseline CDAI value of ≥ 70 pts. The M06-806 Baseline value was defined as the last non-missing value on or before the date of the 1st dose of study drug in M06-806.

  3. Number of Participants in Steroid-free Pediatric Crohn's Disease Activity Index (PCDAI) Remission Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384 ]
    Pediatric Crohn's Disease Activity Index (PCDAI) is an index used to measure disease activity of pediatric patients with Crohn's disease assessing abdominal pain, stool frequency, patient functioning, hematocrit, erythrocyte sedimentation rate, albumin, weight, height, abdomen, perirectal disease, and extraintestinal manifestations. It ranges from 0 to 100; higher scores indicate more active disease. PCDAI corticosteroid-free remission was defined as discontinued corticosteroid use at least 90 consecutive days prior to the respective visit, with a PCDAI ≤ 10 at that visit.

  4. Number of Participants in Steroid-free Crohn's Disease Activity Index (CDAI) Remission Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384 ]
    The CDAI includes 8 variables encompassing subject-reported (symptoms, general well-being) and objective (medication usage, laboratory variables, presence of abdominal mass or complications, and weight) variables. Participants kept track of daily symptoms on a diary card, and the scores were summed for the week. Each item in the CDAI is assigned a specific weight, and the items are totaled to produce the CDAI score. Higher CDAI scores indicate greater disease activity; 0 is the lower limit with no set upper limit. The scale for the score is as follows: < 150 (remission), 150 - 219 (mildly active disease), 220 - 450 (moderately active disease), and > 450 (severely active disease). A CDAI was calculated at each visit for subjects ≥ 13 years old at M06-806 entry. CDAI corticosteroid-free remission was defined as discontinued use at least 90 consecutive days prior to the respective visit and a CDAI < 150 at that visit.

  5. Mean Change From Baseline in Pediatric Crohn's Disease Activity Index (PCDAI) Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384 ]
    Pediatric Crohn's Disease Activity Index (PCDAI) is an index used to measure disease activity of pediatric patients with Crohn's disease assessing abdominal pain, stool frequency, patient functioning, hematocrit, erythrocyte sedimentation rate, albumin, weight, height, abdomen, perirectal disease, and extraintestinal manifestations. It ranges from 0 to 100; higher scores indicate more active disease. The baseline value was defined as the last non-missing value on or before the date of the first dose of study drug in Study M06-806. Negative changes indicate reductions (improvement) in disease activity.

  6. Mean Change From Baseline in Crohn's Disease Activity Index (CDAI) Over Time [ Time Frame: Week 0, 4, 8, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384 ]
