Clinical Study to Assess the Efficacy and Safety of Increased Dose of TA-650 in Patients With Crohn's Disease (CD)

The purpose of this study is to assess the efficacy, safety and pharmacokinetics after administration of 10mg/kg TA-650 every 8 weeks to patients with Crohn's disease showing an insufficient response to previous treatment with 5 mg/kg of REMICADE every 8 weeks.

Inclusion Criteria:

• Patients with Crohn's disease

Exclusion Criteria:

• Severe intestinal strictures (which may have an effect on the number of loose stools or diarrhea or dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy), a diagnosis of short bowel syndrome, or previous stoma surgery
• The presence of significant internal fistula (possibility that surgery might be needed, etc.) is confirmed
• A history of a serious infusion reaction to REMICADE
• Pregnant, lactating, and probably pregnant women
• Patients who have participated in other trials and have been administered other investigational products within 12 weeks before consent
