          2. Diagnosis of Crohn's disease (CD) at least 3 months prior to screening.

          3. Moderate to severe active CD, defined as Crohn's Disease Activity Index (CDAI) ≥ 220
             and ≤ 450.

          4. Presence of mucosal ulcers in at least one segment of the ileum or colon and a Crohn's
             Disease Endoscopic Index of Severity (CDEIS) score ≥ 7 (for patients with isolated
             ileitis, ≥4), as assessed by ileocolonoscopy and confirmed by central independent
             reviewer before randomization

          5. Patients who are naive or experienced to 1 or more TNF antagonists (infliximab,
             adalimumab, or certolizumab pegol) at a dose approved for CD. TNF antagonist
             experienced patients may have stopped anti-TNF treatment due to primary or secondary
             non-responsiveness, intolerance or for other reasons.

          6. Female patients:

             Women of childbearing potential (not surgically sterilized and between menarche and 1
             year postmenopause), that, if sexually active agree to use one of the appropriate
             medically accepted methods of birth control in addition to the consistent and correct
             use of a condom from date of screening until 15 weeks after last administration of
             study medication. Medically accepted methods of contraception are: ethinyl estradiol
             containing contraceptives, diaphragm with spermicide substance, and
             intra-uterine-device, or

                  year of previously occurring menses, and

               3. Negative serum ß-Human Chorionic Gonadotrophin (ß-HCG) test at screening and

               2. Who consistently and correctly use effective method of contraception (i.e.
                  condoms) during the study and 15 weeks after last administration of study
                  medication.

        Exclusion criteria:

          1. Have complications of CD such as strictures, stenoses, short gut syndrome, or any
             other manifestation that might require surgery, could preclude the use of the CDAI to
             assess response to therapy, or would possibly confound the evaluation of benefit from
             treatment with BI 655066.

          2. Have any current or prior abscesses, unless they have been drained and treated at
             least 6 weeks prior to randomization and are not anticipated to require surgery.
             Patients with active fistulas may be included if there is no anticipation of a need
             for surgery and there are currently no abscesses present.

          3. Have had any kind of bowel resection or diversion within 6 months or any other
             intra-abdominal surgery within 3 months prior to screening. Patients with a current
