E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to compare the efficacy, safety, and pharmacokinetics of 200, 400 or 700 mg IV dosing every four weeks of ABT-874 to placebo in subjects who have moderately to severely active Crohn's disease. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
The optional exploratory substudy will be conducted under the same protocol and will require documentation of informed consent separate from the informed consent to participate in the main study. The objective of the substudy is to evaluate the correlation between the response to ABT-874 and pharmacogenomic and pharmacogenetic analysis. |
