Study to Evaluate the Pharmacokinetics, Safety and Efficacy of Two Treatment Modules in Chinese Subjects With Moderate to Severe Crohn's Disease

Blood samples were drawn prior to drug administration. Adalimumab concentrations in serum were determined using a validated enzyme-linked immunosorbent assay (ELISA) method.

The number of participants with an abnormal laboratory result meeting Common Toxicity Criteria (CTC) Version 3.0 (or later) of Grade 3 or higher is summarized. n=the number of participants with CTC Grade <3 at baseline and a post-baseline value for each parameter.

The number of participants with an abnormal laboratory result meeting Common Toxicity Criteria (CTC) Version 3.0 (or later) of Grade 3 or higher is summarized.

Blood pressure and pulse were measured while the participant was sitting. The number of participants with a postbaseline vital sign result that meets Common Toxicity Criteria (CTC) version 3.0 (or later) Grade 3 or higher and is also more extreme than the baseline value is summarized. Terms abbreviated in the table include systolic blood pressure (SBP) and diastolic blood pressure (DBP). Increase and decrease are signified by ↑ and ↓, respectively.

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.

CDAI is used to quantify the signs and symptoms of patients with Crohn's Disease. A score below 150 indicates remission and a score of 220 to 450 reflects moderate to severe disease. Non-responder imputation (NRI) for missing CDAI observations was used.

CDAI is used to quantify the signs and symptoms of patients with Crohn's Disease. Scores range from 0 to approximately 600. A score below 150 indicates remission and a score of 220 to 450 reflects moderate to severe disease. Last observation carried forward (LOCF) for missing CDAI observations was used.

hsCRP was measured from blood samples as a marker for inflammation. Higher levels are indicative of more inflammation. Normal concentration in healthy human serum is usually lower than 3 mg/L, slightly increasing with age. LOCF was used for missing data.

Stool samples for fecal calprotectin were collected before study drug administration when possible. Decreases in calprotectin are associated with decreased inflammation in the gastrointestinal tract. LOCF was used for missing data.

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 2 μg/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. No samples were tested because all samples had adalimumab concentrations >2 μg/mL.
