Descripción detallada

Subjects who are confirmed to meet all of the inclusion criteria and none of the exclusion criteria during screening period (≤ 21 days) will be given subcutaneous injections of open-label adalimumab 80 mg eow from Week 0 to Week 50. If a subject has an inadequate response at or after Week 8, the subject may be withdrawn from the study. Self-injection of study drug is permitted for the subjects who are willing to perform self-injection, if the investigator decided as appropriate. Disease activity will be evaluated by Crohn's disease activity index (CDAI) at Screening, Week 0 and every 4 weeks until Week 52. Follow-up will be performed at 70 days after the last dose of study drug by visit or telephone.

Number of Participants With Adverse Events (AEs)
Periodo de tiempo: 60 weeks

An AE is any untoward medical occurrence in a participant which does not necessarily have a causal relationship with this treatment. A serious AE (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent events (TEAEs or TESAE) are defined as any event that began or worsened in severity after the first dose of study drug. The investigator assessed the relationship of each event to the use of study drug as either Reasonable possibility or No reasonable possibility of being related to study drug.

For more details on adverse events please see the AE section below.

Periodo de tiempo
Change in Mean Serum Adalimumab Concentration From Baseline (Week 0) to Week 52
Periodo de tiempo: Baseline (Week 0) to Week 52
Blood samples were drawn prior to drug administration. Adalimumab concentrations in serum were determined using a validated heterogeneous electrochemiluminescence (ECL)-immunoassay method. The assay captures adalimumab via biotinylated anti-idiotypic antibody, and detects it via sulfo-tagged TNF-alpha. n=the number of participants with available data at each time point.
Baseline (Week 0) to Week 52
Change in Number of Subjects Positive for Anti-Adalimumab Antibodies (AAA) From Baseline to Week 52
Periodo de tiempo: Baseline (Week 0) to Week 52
Serum samples with adalimumab concentration below 2 μg/mL were selected for AAA analyses. Samples were considered AAA positive if the measured AAA concentration was above 20 ng/mL. A subject was considered to be AAA positive if the subject had at least one AAA positive sample observed within 30 days following the subject's last adalimumab dose.
