Study Design

  • The method used to assign participants to an arm of a clinical trial, for example Randomized (assigned by chance) versus Non-randomized.



  • A target outcome that the study’s protocol aims to evaluate - things like: the occurrence of a disease, a symptom, sign, or lab abnormality, among others.

    Endpoint Classification

    Safety/Efficacy Study

  • The general design that shows how the medical interventions will be assigned to the participants, e.g., whether all patients will receive the same drug, or if different groups receive two or more different treatments in a particular order.

    Intervention Model

    Parallel Assignment

  • The general design that describes the strategy for identifying and following up with participants during observational studies.


    Double Blind (Subject, Investigator)

  • This is the single main reason for carrying out the clinical trial. Reasons can include: treatment, prevention, diagnostic advances, supportive care, screening, or health services research, among others.



    1. Men or women 18-75 years at the time of consent.
    2. Diagnosis of Crohn's disease at least 3 months prior to screening.
    3. Moderate to severe active Crohn's disease, defined as CDAI >or=220 and <or=450.
    4. Presence of mucosal ulcers in at least one segment of the ileum or colon and a CDEIS score >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 Crohn's Disease.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
      • Surgically sterilized female patients with documentation of prior hysterectomy, tubal ligation or complete bilateral oophorectomy, or
      • Postmenopausal women with postmenopausal is defined as permanent cessation = 1 year of previously occurring menses, and
      • Negative serum ß-Human Chorionic Gonadotrophin (ß-HCG) test at screening and urine pregnancy test prior to randomization.

      Male patients:

      • Who are documented to be sterile, or
      • Who consistently and correctly use effective method of contraception (i.e. condoms) during the study and 15 weeks after last administration of study medication.
    7. Have the capacity to understand and sign an informed consent form.
    8. Be able to adhere to the study visit schedule and other protocol requirements.
    1. Have complications of Crohn´s Disease 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 ileostomy or colostomy are excluded.
    4. Have received treatment with:
      • Total parenteral nutrition (TPN) within 2 weeks of screening.
      • Any dose of ustekinumab (Stelara®).
      • Anti-TNF therapy = 8 weeks prior to the first administration of study medication or any other biologic = 8 weeks prior to the first administration of study drug or within 5 times the half-life of the biologic prior to the first administration of study agent, whichever is longer.
      • Natalizumab, efalizumab, or agents that deplete B or T cells (e.g., rituximab, alemtuzumab, or visilizumab) within 6 months of screening, or, if after receiving these agents, evidence is available at screening of persistent depletion of the targeted lymphocyte population.
      • Any investigational drug within the previous 4 weeks or 5 times the half-life of the investigational agent prior to the first administration of study agent, whichever is longer.
      • Regular daily use of opioids for medical reasons within previous 3 months prior to the first administration of study agent.
      • Rectal 5-ASA compounds, parenteral or rectal corticosteroids must have been discontinued at least 4 weeks prior to visit 2.
      • Cannot adhere to the concomitant medication requirements specified in section 4.2.2.
    5. Are pregnant, nursing, or planning pregnancy (both men and women) while enrolled in the study, or within 15 weeks after receiving the last dose of study medication.
    6. Have used apheresis (e.g., Adacolumn apheresis) = 2 weeks prior to screening.
