4. Subjects with a history of inadequate treatment response or intolerance (as defined by the Investigator) to at least one of the following therapies for Crohn’s disease:
• Corticosteroids.
• Azathioprine/6-Mercaptopurine.

5. Subjects currently receiving any of the following treatments for Crohn’s disease are eligible provided they are on stable dose for designated period of time and throughout the study:
• Oral 5-ASA or sulfasalazine stable dose for at least 4 weeks prior to baseline.
• Oral corticosteroids (prednisolone up to 30 mg/day; budesonide up to 9 mg/day) stable dose for at least 2 weeks prior to baseline.
• Chronic treatment for Crohn’s disease with antibiotics (e.g. metronidazole, ciprofloxacin, rifaximin) stable dose for at least 2 weeks prior to baseline.
• Rectally administered formulation of corticosteroids or 5-ASA stable dose for at least 2 weeks prior to baseline.
6. Subjects with presence of ulceration at screening/baseline colonoscopy as defined by the Simple Endoscopic Score for Crohn’s Disease (SES-CD): aphthous ulcers (0.1 to 0.5 cm), large ulcers (0.5 to 2 cm), or very large ulcers (>2 cm).
7. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as defined by all of the following:
• A negative QuantiFERON®-TB Gold In-Tube test or, if unavailable, a Mantoux Purified Protein Derivative skin test, concentration as per local medical standard of practice, result of <5 mm of induration, performed within the 3 months prior to screening. [It is recommended that subjects with a history of Bacille Calmette Guérin (BCG) vaccination be tested with the QuantiFERON®-TB Gold In-Tube test.].
• A chest radiograph taken at or within the 3 months prior to screening, without changes suggestive of active TB infection as determined by a qualified radiologist.
• No history of either untreated or inadequately treated latent or active TB infection.
• If a subject has previously received an adequate course of therapy for either latent (9 months of isoniazid in a locale where rates of primary multi-drug resistant TB infection are <5% or an acceptable alternative regimen) or active (acceptable multi-drug regimen) TB infection, neither a PPD test nor a QuantiFERON® -TB Gold
In-Tube test need be obtained, but a chest radiograph must still be obtained if not done so within the prior 3.months. Documentation of adequate treatment for TB will be obtained prior to first dose of study drug.
• A subject who is currently being treated for active TB infection is to be excluded.
• A subject who is currently being treated for latent TB infection can only be enrolled with confirmation of current incidence rates of multi-drug resistant TB infection in the locale, documentation of an adequate treatment regimen, and with prior approval by the Sponsor.
8. Women of childbearing potential must test negative for pregnancy prior to study enrolment.
9. Sexually active females of childbearing potential are required to use adequate contraceptive methods during the study period and until completion of the follow-up procedures. (Further description of the requirements and a list of contraceptives considered effective and acceptable for use in this trial are found in Section 4.4 Life Style
Guidelines in the protocol).
10. Subjects receiving non-prohibited concomitant medications for any reason, must be on a stable regimen, which is defined as not starting a new medication or changing dosage of a current medication within 7 days or 5 half-lives (whichever is longer) prior to baseline and for the duration of the study.
11. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
12. Evidence of a personally signed and dated informed consent document(s) indicating that the subject has been informed of all pertinent aspects of the study.

| EOT in all participating countries is defined as LSLV. EOT in a Member State of the EU is defined as time at which it is deemed that sufficient subjects have been recruited & completed the study as stated in regulatory application (ie, Clinical Study Application) ðics application in the Member State (MS). Poor recruitment (recruiting less than the anticipated number in the CTA) by a MS is not a reason for premature termination but is considered a normal conclusion to the study in that MS. |
