Brief summary
The purpose of this study is to investigate the efficacy, safety and pharmacokinetics after dose escalation in Japanese subjects with Crohn's Disease.
Detailed description
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 If a subject has an inadequate response at or after Week 8, the subject may be withdrawn from the study.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.
Interventions
Adalimumab pre-filled syringe, administered by subcutaneous injection.

Eligibility
Inclusion criteria
* Subject ≥ 15 years of age at the time of informed consent. * Subject with Crohn's disease who received induction treatment of commercially available Humira® (160 mg initially and 80 mg at 2 weeks after initial dose), achieved response after initial dose, and then lost response during maintenance treatment with Humira®. * Subject with elevated C-reactive Protein (CRP) at Screening. * If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy and/or hysterectomy) or is of childbearing potential and is practicing an approved method of birth control throughout the study and for 150 days after the last dose of study drug. * Subject has a negative tuberculosis (TB) screening assessment. If the subject has evidence of a latent TB infection; the subject must initiate and complete a minimum of 21 days of an ongoing TB prophylaxis (in such case, screening period can be prolonged until 21 days past after initiation of prophylaxis and study drug is administered) or have documented completion of a full course of TB prophylaxis, prior to Week 0.

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.
