NCT01523639

Brief Summary

This multicenter randomized, placebo-controlled phase II study will enroll 132 first-line palliative treated subjects with metastatic KRAS wild type CRC. Subjects with histologically confirmed, KRAS wild-type CRC without previous chemo-therapy for metastatic disease will be screened for this study. Approximately 10 sites in Austria will participate in the study. Subjects will be randomized in a ratio of 1:1 into two groups.
