E.3 | Principal inclusion criteria |
Subject eligibility should be reviewed and documented by an
appropriately qualified member of the investigator's study team before
subjects are included in the study. Subjects must meet all of the
following inclusion criteria to be eligible for enrollment into the study:
1. Male or female subjects between the ages of ≥18 and ≤75 years at
screening.
2. Subjects with documented clinical diagnosis of Crohn's disease for at
least 6 months prior to screening.

defined by a baseline score of Crohn's Disease Activity Index (CDAI) of ≥
220 to ≤450 at baseline.
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.
• Methotrexate.
• Anti TNF therapy (Infliximab; Adalimumab; Certolizumab pegol).
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 (eg,
metronidazole, 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.
• Seton placement before enrollment must remain in place during the
study.
6. Subjects with presence of ulceration at screening/baseline
colonoscopy as documented 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 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 (e.g., 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 QFT G test is needed, but a negative
chest radiograph must still be obtained if not performed within 3 months
prior to screening. 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.
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.
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 indicating that the subject (or a legal representative) 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. |
