IUDs may fail during azathioprine treatment. Alternative or additional contraceptive measures are advised, if azathioprine is initiated • Oral or parenteral contraceptives for 3 months prior to study drug administration • A vasectomized partner o Male subjects must agree to use an acceptable form of birth control, listed above at the start of azathioprine administration and for 90 days after last dose of azathioprine. Males should also commit to inform his partner(s) about it and to report any pregnancy to the investigator. o If female, subject is not breast-feeding throughout the study and for 150 days after last dose. o Subjects or his/her legal representative have voluntarily signed and dated an informed consent approved by and compliant with the requirements of this study protocol which has been approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC) o Adequate cardiac, renal and hepatic function as determined by the Principal Investigator and demonstrated by Screening laboratory evaluations, questionnaires and physical examination results that do not indicate an abnormal clinical condition which would place the subject at undue risk and thus preclude subject participation in the study o Subject with a negative TB Screening Assessment [(including a PPD test < 5 mm and/or negative QuantiFERON-TB Gold test or equivalent and negative CXR (PA and lateral view)] at Screening
|

E.4 | Principal exclusion criteria |
o Absence of written consent.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint will be combined remission (as defined in the ADMIRE-CD protocol25) at week 12 defined as: - 100% of the fistula tracts without any drainage by the external openings (occurring spontaneously or after gentle finger compression) - absence of collections >2 cm of the treated perianal fistulas confirmed by masked central MRI.
Patient requiring UST optimization will be considered in failure but will be followed until week 48
