Key inclusion & exclusion criteria

Inclusion criteria:
Subject eligibility should be reviewed and documented by an appropriately qualified member of the investigator’s study team before subjects are included in the study. Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the study:
1. Male or female subjects between the ages of =18 and =75 years at screening.
2. Subjects with documented clinical diagnosis of Crohn’s disease (CD) for at least 6 months prior to screening.
3. Subjects with active moderate to severe ileal, ileocolic, or colonic CD defined by a baseline score of Crohn’s Disease Activity Index (CDAI) of =220 to =450 at baseline.
4. Subjects with a history of inadequate treatment response or intolerance (as defined by the Investigator) to at least one of the following therapies for Crohn’s disease:
• Corticosteroids.
• Azathioprine/6-Mercaptopurine.
• Methotrexate.
• Anti-TNF therapy (Infliximab; Adalimumab; Certolizumab pegol).
5. Subjects currently receiving any of the following treatments for Crohn’s disease are eligible provided they are on stable dose for designated period of time and throughout the study:
• Oral 5-ASA or sulfasalazine stable dose for at least 4 weeks prior to baseline.
• Oral corticosteroids (prednisolone up to 30 mg/day; budesonide up to 9 mg/day) stable dose for at least 2 weeks prior to baseline.
• Chronic treatment for Crohn’s disease with antibiotics (e.g. metronidazole, rifaximin) stable dose for at least 2 weeks prior to baseline.
• Rectally administered formulation of corticosteroids or 5-ASA stable dose for at least 2 weeks prior to baseline.
• Seton placement before enrollment must remain in place during the study
6. Subjects with presence of ulceration at screening/baseline colonoscopy as documented by the Simple Endoscopic Score for Crohn’s Disease (SES-CD): aphthous ulcers (0.1 to 0.5 cm), large ulcers (0.5 to 2 cm), or very large ulcers (>2 cm).
7. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as defined by all of the following:
•A negative QuantiFERON-TB Gold (QFT-G) In-Tube test documented within 3 months prior to or during screening. If initial and repeat QFT-G tests are indeterminate, a negative Mantoux Purified Protein Derivative (PPD) tuberculin skin test (with a result of <5 mm of induration), documented within 3 months prior to or during screening is required. [Subjects with a history of Bacille Calmette Guérin (BCG) vaccination must have a negative QFT-G test.].
• A chest radiograph taken at or within the 3 months prior to screening, without changes suggestive of active TB infection as determined by a qualified radiologist.
• No history of either untreated or inadequately treated latent or active TB infection.
• If a subject has previously received an adequate course of therapy for either latent (eg.9 months of isoniazid in a locale where rates of primary multi-drug resistant TB infection are <5% or an acceptable alternative regimen) or active (acceptable multi-drug regimen) TB infection, neither a PPD test nor a QFT G test is needed, but a negative chest radiograph must still be obtained if not performed within 3 months prior to screening. Documentation of adequate treatment for TB will be obtained prior to first dose of study drug.
• A subject who is currently being treated for active TB infection is to be excluded.
• A subject who is currently being treated for latent TB infection can only be enrolled with c
Exclusion criteria:
1.Diagnosis of indeterminate colitis,ulcerative colitis (UC),or findings suggestive of UC.2.Subjects diagnosed with CD but without prior exposure to treatment (i.e treatment-naïve) or having failed or been intolerant to treatment solely with 5-ASA containing compounds.3.Subjects receiving treatment for CD (see protocol for the list of treatments)4.Other investigational or marketed biologics withimmunomodulatory properties within 3months prior to baseline. 5.Subjects who have previously received natalizumab or any anti-adhesion molecule, within 1year PTB. 6.Leukocyte apheresis including selective lymphocyte, monocyte, or granulocyte apheresis,or plasma exchange within 6months. 7.Subjects who have previously participated in any study of tofacitinib. 8.Participation in other interventional clinical studies within 3months PTB/or during study. 9.History of symptomatic obstructive strictures unless the stricture has been surgically treated with dilation without recurrence of symptoms for at least 6months prior to enrollment or an active ostomy. 10.History of total colectomy or subtotal colectomy to the extent that it precludes the subject from having any formed stool,extensive small bowel resection(>100cm) or short bowel syndrome.11.History of bowel surgery within 6months PTB. 12.Subjects likely to require any type of surgery during the study period.13.Fecal culture/toxin assay indicating presence of pathogenic infection.14.Presence of active (draining) fistulae, intrabdominal or perineal collection or abscess (Subjects with prior history of fistulae including entero-cutaneous, entero-enteric, entero-vesicular,entero-vaginal, or perineal fistulae or abdominal or perineal abscess will require MRI of abdomen/pelvis prior to randomization) 15.Subjects on elemental diet used for treating CD within 7days PTB. 16.Subjects with blood dyscrasias at screening 17.Subjects with evidence of or suspected liver disease i.e. liver injury due to MTX or primary sclerosing cholangitis.18.Subjects with estimated GFR =40 ml/min at screening, based on Cockcroft-Gault calculation. 19.Subjects with total bilirubin,AST or ALT more than 1.5times upper limit of normal at screening.20.Subjects with current or recent history of severe, progressive, or uncontrolled renal, hepatic, hematological, GI,metabolic, endocrine, pulmonary, cardiac or neurological disease.21.Subjects who have been vaccinated with any live or attenuated virus vaccine within 6weeks PTB or scheduled to receive live virus vaccination during study period &for 6weeks after last dose of study drug. 22.Subjects with history of any lymphoproliferative disorder, history of lymphoma, leukemia, myeloproliferative disorders, multiple myeloma, or signs& symptoms suggestive of current lymphatic disease. 23.Subjects with clinically significant infections currently or within 6months PTB, a history of any infection requiring antimicrobial therapy within 2weeks PTB or history of any infection otherwise judged by the investigator to have potential for exacerbation by participation in study. 24.Subjects with a history of more than one episode of herpes zoster (HZ), a history of disseminated HZ or disseminated herpes simplex. 25.Subjects with prior treatment with lymphocyte-depleting agents/therapies. Subjects who have received rituximab or other selective B lymphocyte depleting agents are eligible if they have not received such therapy for at
least 1year prior to baseline 26.Subjects with any condition possibly
