Inclusion criteria
Inclusion criteria: 1. (AMAM Main Trial): have given written informed consent approved by the Ethical Review Board (ERB) governing the site. 1. (AMAM Adolescent Addendum): the investigator, or a person designated by the investigator, will obtain written informed consent approved by the Ethical Review Board (ERB) from each study participant or the participant's parent/legal guardian and the subject*s assent, when applicable, before any study-specific activity is performed. The investigator will retain the original copy of each participant's signed consent/assent document. 2. (AMAM Main Trial): are male or female patients >=18 and 40 kgs with moderate to severely active CD as defined in points 5 and 6 below at the time of initial screening/consent. [2a] male patients: no male contraception required except in compliance with specific local government study requirements, [2b] female patients: women of childbearing potential: A. must test negative for pregnancy prior to initiation of treatment as indicated by a negative serum pregnancy test at the screening visit followed by a negative urine pregnancy test within 24 hours prior to exposure. AND B. must agree to either remain abstinent, if complete abstinence is their preferred and usual lifestyle, or remain in same-sex relationships, if part of their preferred and usual lifestyle, without sexual relationships with males. Periodic abstinence (for example, calendar, ovulation, symptothermal, or post-ovulation methods), declaration of abstinence just for the duration of a trial, and withdrawal are not acceptable methods of contraception. OR must use 2 effective methods of contraception for the entirety of the study. Abstinence or contraception must continue following completion of study drug administration for 20 weeks. i. Two effective methods of contraception (such as male or female condoms with spermicide, diaphragms with spermicide, or cervical sponges) will be used. The participant may choose to use a double barrier method of contraception. Barrier protection methods without concomitant use of a spermicide are not a reliable or acceptable method. Thus, each barrier method must include use of a spermicide. It should be noted that the use of male and female condoms as a double barrier method is not considered acceptable because of the high failure rate when these methods are combined. ii. Of note, 1 of the 2 methods of contraception may be a highly effective (less than 1% failure rate) method of contraception (such as combination oral contraceptives, implanted contraceptives, or intrauterine devices). women not of childbearing potential may participate and include those who are: A. infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, or tubal ligation), congenital anomaly such as mullerian agenesis; or B postmenopausal - defined as either: i. a woman at least 40 years of age with an intact uterus, not on hormone therapy, who has had either * cessation of menses for at least 1 year without an alternative medical cause AND * at least 6 months of spontaneous amenorrhea with a folliclestimulating hormone (FSH) level >40 mIU/mL; or ii. a woman 55 years or older n
Exclusion criteria
Exclusion criteria: Participants will be excluded from study enrollment if they meet any of the following criteria within the screening period, unless otherwise specified below. For rescreening activities within the screening period, see Section 5.4. Gastrointestinal Exclusion Criteria [12] are participants who: [12a] have a current diagnosis of UC, IBD-unclassified (formerly known as indeterminate colitis). [12b] currently have or are suspected to have an abscess. Recent cutaneous and perianal abscesses are not exclusionary if drained, adequately treated and resolved at least 3 weeks prior to baseline or 8 weeks prior to baseline for intra-abdominal abscesses, provided that there is no anticipated need for any further surgery. [13] have a stoma, ileoanal pouch or ostomy. [14] have had a bowel resection within 6 months, or any kind of intra-abdominal surgery within 3 months of baseline (Visit 2). [15] have complications of CD such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestation that might be anticipated to require surgery within 6 months after screening, could preclude the use of the SES-CD, CDAI, or PRO to assess response to therapy, or would possibly confound the ability to assess the effect of treatment. Adenoma, Dysplasia, and Gastrointestinal Cancer Exclusion Criteria [16] have any history or current evidence of cancer of the gastrointestinal tract. [17] have any current sporadic adenoma without dysplasia that has not been removed. Once completely removed, the patient is eligible for study. [18] have any evidence of colonic dysplasia. Criteria for Discontinuing Prohibited Medications [19] have received any of the following for treatment of CD within the time frames specified below: [19a] corticosteroid enemas, corticosteroid suppositories or a course of IV corticosteroids within 2 weeks prior to screening endoscopy. [19b] 5-ASA enemas or 5-ASA suppositories within 2 weeks prior to screening endoscopy. [19c] immunomodulatory medications, including oral cyclosporine, IV cyclosporine, tacrolimus, mycophenolate mofetil, thalidomide or Janus kinase inhibitors within 4 weeks prior to the screening endoscopy. * AZA, 6-MP, and MTX are allowed at stable doses (Appendix 10.7). * Other immunomodulatory medications should be discussed with the sponsor prior to screening. [19d] anti-TNF antibodies (for example, infliximab, adalimumab, or certolizumab pegol) within 4 weeks prior to screening endoscopy. [19e] anti-integrin antibodies (for example, vedolizumab) within 4 weeks prior to screening endoscopy. [19f] agents that deplete B or T cells (for example, rituximab, alemtuzumab, or visilizumab) within 12 months of baseline (Visit 2). Patients remain excluded if there is evidence of persistent targeted lymphocyte depletion at the time of screening endoscopy. [19g] any investigational nonbiologic therapy within 4 weeks prior to the screening endoscopy or within 5 half-lives prior to the screening endoscopy, whichever is longer. [19h] any investigational biologic therapy within 8 weeks prior to the screening endoscopy or within 5 half-lives prior to the screening endoscopy, whichever is longer. [19i] leukocyte apheresis (leukapheresis, for example, Adacolumn) within 3 weeks prior to screening endoscopy. [19j] in
