| E.3 | Principal inclusion criteria |
1. Male or female subjects aged 18 to 75 years (at Screening), inclusive
2. Subject must provide written informed consent prior to any study-related procedures, and
have the ability to comply with the Table of Events
3. Subject has signs and symptoms consistent with a diagnosis of CD for at least 3 months (prior to first IP administration). The diagnosis should be confirmed by clinical and endoscopic evidence and corroborated by a histology report. (Note: endoscopy and histopathology confirmation may be obtained during Screening if no prior report is readily available).
4. Subject has met each of the following 2 criteria:
a CDAI score ≥ 220 and ≤ 450
an average daily stool frequency ≥ 4 points and/or an abdominal pain of ≥ 2 points
5. Subject has a SES-CD score of ≥ 6 (or SES-CD ≥ 4 in subjects with isolated ileal disease).
6. Subject has an inadequate response or loss of response to or is intolerant of at least 1 of
the following systemic CD treatments: corticosteroids, immunomodulators, biologic therapies (eg, ustekinumab, TNFα antagonists, or vedolizumab)
7. If the subject is taking the following background therapies for CD, he/she must be on a
stable dose must be maintained throughout the study beginning from the screening period as indicated below:
oral aminosalicylates (eg, mesalamine, sulfasalazine, olsalazine, balsalazide) with a stable dose for at least 3 weeks prior to Screening endoscopy
prednisone (doses ≤ 20 mg per day) or equivalent with a stable dose for at least 2 weeks prior to Screening endoscopy
budesonide therapy (doses ≤ 9 mg per day) or beclomethasone doses ≤ 5 mg/day at a stable dose for at least 2 weeks prior to the Screening endoscopy
8. Subject at high risk (ie, family history, CD duration) for colonic malignancy has documented evidence of having had a surveillance colonoscopy within the last 2 years or according to local and national medical guidelines to evaluate for polyps, dysplasia, or malignancy. If there is no recent history of surveillance colonoscopy, this can be done as part of the colonoscopy performed during Screening. Any visualized adenomatous polyps must be removed and any suspicious lesion confirmed free of cancer and/or dysplasia prior to randomization.
9. Female subjects of childbearing potential (FCPB):
Note: For the purposes of this study, a female patient is considered to be of childbearing potential if she 1) has not undergone a hysterectomy
(the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for
at least 24 consecutive months (that is, has had menses at any time during the preceding 24 consecutive months).
Must agree to practice a highly effective method of contraception throughout the study until completion of the 90-day Safety Follow-Up Visit. Examples of effective methods of contraception are those that alone or in combination result in a failure rate of a Pearl Index of less than 1% per year when used consistently and correctly.
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
10. Subjects must have documentation of positive varicella zoster virus (VZV) immunoglobulin G (IgG) antibody status or complete VZV vaccination at least 30 days prior to randomization. |
|
| E.4 | Principal exclusion criteria |
1. Subject has any clinically relevant cardiovascular hepatic,neurological, pulmonary [severe respiratory disease (pulmonary fibrosis or chronic obstructive pulmonary disease)], ophthalmological,endocrine, psychiatric, or other major systemic disease making implementation of the protocol or interpretation of the study difficult or that would put the subject at risk by participating in the study. 2.Subject is likely to require, in the physician's judgment, bowel resection within 12 weeks of entry into the study. 3. Subject has a diagnosis of UC,indeterminate colitis, radiation colitis, or ischemic colitis, or has strictures with prestenotic dilatation. Any other modality used in addition to the colonoscopy to assess this criterion must be discussed
with the Medical Monitor. 4. Subject has current stoma, ilealanal pouch anastomosis, fistula that is likely to require, surgical or medical intervention within 12 weeks of entry into the study or need for ileostomy or colostomy. 5. Subject has extensive small bowel resection
(> 100 cm) or known diagnosis of short bowel syndrome, or subject requires total parenteral nutrition. 6. Subject has suspected or diagnosed intra-abdominal or perianal abscess that has not been appropriately treated. 7. Subject has documentation of positive test for toxin producing C. difficile, or PCR examination of the stool. 8. Subject has documentation of positive examination for pathogens 9. Subject is pregnant, lactating, or has a positive serum β-hCG test measured during Screening. 10. Subject has any condition that would make implementation of the protocol or interpretation of the study difficult. 11. Subject has a history of diabetes mellitus type 1, or uncontrolled diabetes mellitus type 2 with hemoglobin A1c (HbA1c) > 9%, or is a
diabetic subject with significant comorbid conditions such as retinopathy or nephropathy. 12. Subject has a history of uveitis or macular edema. 13. Subject has a known active bacterial, viral, fungal, mycobacterial infection (including tuberculosis or atypical mycobacterial disease) or any major episode of infection that either required hospitalization or treatment with IV antibiotics within 30 days of Screening or treatment with oral antibiotics within 14 days of Screening. •In the case of known SARS-CoV-2 infection, symptoms must have completely resolved and based on Investigator assessment in consultation with the Clinical Trial Physician / Medical Monitor, there are no sequelae that would place the subject at a higher risk of receiving investigational treatment. SARS-CoV 2 testing may be conducted prior to randomization if required by and in accordance with national, local or institutional guidelines. 14. History or known presence of recurrent or chronic infection (eg, hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV); recurrent urinary tract infections are allowed. 15.

placebo. 18. Prior participation in an ozanimod clinical study 19. Subject has a history of primary nonresponse to 2 or more approved biologic agents or has been treated with 4 or more biologics for CD 20. Subject has been treated with a biologic agent within 8 weeks or 5 elimination half-lives(whichever is shorter) prior to the first dose of IP 21. Subject has a history of treatment with an investigational agent within 5 elimination half-lives of that agent prior to the first dose of IP 22. Subject has received a live or live attenuated vaccine within 4 weeks prior to the first dose of IP 23. Subject has received previous treatment with lymphocyte-depleting therapies 24.

Subject has a history of treatment with IVIg, or plasmapheresis within 3 months prior to first dose of IP 28. Subject has discontinued oral 5-ASA or corticosteroids within 2 weeks prior to the screening endoscopy. 29.Subject has received rectal therapy within 2 weeks of screening endoscopy or has planned concurrent use of any per rectum therapy. 30. Subject has planned concurrent treatment with immunomodulatory
agents after randomization.
