Inclusion Criteria

1.Each subject must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study. All subjects must be capable of signing their own ICF and complete the eDiary.
2. Subject must be a man or woman between 18 years and 75 (inclusive) years of age.
3. Has moderate to severe CD with a CDAI score between 220 and 450 (inclusive) and a histologic diagnosis of CD for at least 3 months before screening. The histological diagnosis should be confirmed locally from the screening colonoscopy if not previously documented at the site.
4. Has screening laboratory test results within the following parameters:
a. Hemoglobin =8 g/dL
b. WBC =2000 cells/µL
c. Neutrophils =1500 cells/µL
d. Creatinine =1.7 mg/dL
e. Serum AST or ALT =2 x upper limit of normal (ULN)
f. Total bilirubin =2 x ULN
g. CPK =3 x ULN
h. LDH =3 x ULN
5.SES-CD score =6 or =4 for ileal-only disease
6. Subject may be either biologic naïve or biologic experienced. Subjects who have had prior experience with anti-TNF, anti-integrin, or anti-MAdCAM-1 treatment would be eligible if they were primary nonresponders, secondary nonresponders, intolerant or allergic to anti-TNF agents (e.g. infliximab), or stopped such treatment for other reasons Subjects who have had prior experience with anti-IL-12/23 (e.g. ustekinumab)or anti-IL-23 agents would be eligible if they were responders, secondary nonresponders, or stopped the treatment due to intolerance or reasons unrelated to efficacy. Primary nonresponders to anti-IL-12/23 or anti-23 are excluded (see exclusion #6).
7. Female subjects must meet the following inclusion criteria:
a. Women not of childbearing potential:
Postmenopausal is defined as being >45 years of age with amenorrhea for at least 18 months) or >45 years of age with amenorrhea for at least 12 months and a confirmatory serum follicle stimulating hormone (FSH) level >40 IU/L with luteinizing hormone (LH) level >40 IU/L in woman not receiving hormone replacement therapy; permanently sterilized (eg, hysterectomy, bilateral salpingectomy, bilateral oophorectomy); or otherwise be incapable of pregnancy. Note: tubal ligation is not considered permanent sterilization.
b. Women of childbearing potential:
1) Must have a negative serum ß-human chorionic gonadotropin (ß-hCG) at screening and a negative urine pregnancy test at Week 0 prior to dosing
2) Must practice a highly effective method of birth control ( <1% failure rate) consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies such as established use (>3 months) of oral, injected or implanted highly effective hormonal methods of contraception; placement of an intrauterine device or intrauterine system; male partner sterilization (the vasectomized partner should be the sole partner for that subject); true abstinence (when this is in line with the preferred and usual lifestyle of the subject).
3).Must agree to use highly effective methods of birth control throughout the study for 3 months after receiving the last dose

Exclusion Criteria

2.Untreated active external or perianal fistula or abscess.
3.Other gastrointestinal inflammatory diseases.
4.Any malignancy or lymphoproliferative disorder other than nonmelanoma cutaneous malignancies or cervical carcinoma
5.Colon cancer or severe dysplasia. Subjects with CD for =8 years involving the colon are not excluded if they had a colonoscopy to assess for the presence of dysplasia w/in 1 year before baseline or if they had a colonoscopy at the scr. (Any polyps revealed during the scr. endoscopy should be appr evaluated and removed. Larger polyps >1 cm should be
fully resected and histologically evaluated)
6.Is a primary nonresponder to anti-IL-12/23 or anti-IL-23 biologic tx
7.Prev treatment w/natalizumab
8.Treatment w/tofacitinib, cyclosporine, or other immunosuppressives incl biologics w/in 5 half-lives before randomization. A serum concentration level below the limit of quantitation is acceptable
9.Has been on a variety of doses of thiopurines or MTX w/in 8 wks of scr
10.Treatment w/unstable doses of mesalamine (5-ASA) or chronic antibiotics within 30 days before scr
11.Treatment w/oral prednisone or prednisolone >20 mg or budesonide >6 mg per day, or other corticosteroids of equivalent doses, w/in 2 wks of scr. Doses of steroids must remain stable from at least 2wks prior to
scr to wk12. Tx w/rectal steroids or systemic corticosteroids (IV os IM) is prohibited throughout the study except for the tx of AE
12.Treatment w/proton pump inhibitors (PPIs) or cimetidine within 7 days before baseline. Subjs may take non-cimetidine H2 receptor agonists incl. high doses for RGRD. Antacids may be used except w/in 2 hrs of dosing

14. Subj is receiving and/or is anticipated to require substrates of pglycoprotein during the study
15.Ongoing, chronic or recurrent infectious disease, including but not limited to endemic fungal infections, chronic renal infection, chronic chest infection, recurrent urinary tract infection, or a history of serious infection
