8. Contraception:
•Female patient of childbearing potential (entering the study after a menstrual period and who has a negative pregnancy test), who agrees to use a highly effective method of contraception and an acceptable method of contraception by her male partner during the study and for 3 months after the last treatment intake.
•Male patient with a female partner of childbearing potential who agrees to use a highly effective method of contraception and an acceptable method of contraception by his female partner during the study and for 3 months after the last treatment intake or who agrees to use an acceptable method of contraception and a highly effective method of contraception by his female partner during the study and for 3 months after the last treatment intake.
•Highly effective methods of contraception include:
- Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, or transdermal

- Intrauterine device (IUD)
- Intrauterine hormone-releasing system (IUS)
- Bilateral tubal occlusion
- Vasectomized male (azoospermia assessed medically)
- Sexual abstinence (Its reliability should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient)
•Acceptable methods of contraception include:
- Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the primary mode of a
Exclusion criteria:

5.Patient likely to require emergency surgery for persistent intestinal obstruction, bowel perforation, uncontrolled bleeding or abdominal abscess infection, in the investigator’s opinion and patients who have undergone bowel surgery within the 3 months prior to study treatment initiation.
6.Patient with previous proctocolectomy or with symptomatic stricture or with abscess
7.Patient with a clinically relevant short bowel syndrome, in the opinion of the investigator.
8.Patient whose symptoms are believed to be largely due to the presence of fixed fibrotic strictures in the opinion of the investigator.
9.Patient with a history of malignant neoplastic diseases of the bowel including diseases occurring more than 5 years before the inclusion in the study.
10.Patient with active infection (HBV, HCV, HIV, EBV, CMV)
