Purpose of Study 

This is a randomized, double-blind, placebo-controlled, parallel group, multiple dose study to evaluate the efficacy of AMG 181 compared with placebo as measured by the proportion of subjects in remission (CDAI score < 150) at week 8 (primary endpoint). After completing all screening assessments and meeting all eligibility criteria, subjects will be randomized to receive placebo or AMG 181 at various doses per protocol. A maximum of approximately 80% of subjects with any prior anti-TNF agent use will be allowed in the study. At the end of the double blind period, subjects will enter an open-label period during which all subjects will receive open-label AMG 181 at a single dose level according to protocol. Subjects who fail to achieve minimal improvement, or experience disease worsening after initial response are eligible to enter the open-label period early beginning at week 12 or after. Subjects that complete the open-label period or early terminate from the study will enter the 2 year safety follow up period.
