Show details

1. Male and/or female subjects 18 years to 75 years of age

2. Documented diagnosis of ileal, ileocolonic, or colonic CD with a minimum disease
duration of 3 months, as determined by endoscopic and histopathology assessment.

3. Endoscopic confirmation of active disease with total SES CD total score of at least 7.
For isolated ileal disease, SES CD total score should be at least 4.

4. An average daily liquid/soft stool frequency (SF) greater than or equal to 2.5 or
daily abdominal pain (AP) greater than or equal to 2.0.

5. Must have inadequate response to, loss of response to, or intolerance to at least one
conventional therapy for CD:

•Steroids; Immunosuppressants (azathioprine [AZA], 6 MP, or methotrexate [MTX]); Anti
TNF inhibitors (infliximab, adalimumab,certolizumab); Anti integrin inhibitors (eg,
vedolizumab); Anti IL 12/23 inhibitor (ustekinumab).

6. Subjects currently receiving the following treatment for CD are eligible providing
they have been on stable doses as described below:

- Oral corticosteroids (prednisone or equivalent up to 25 mg/day; budesonide up to
9 mg/day). Stable dose for at least 2 weeks prior to baseline. If oral
corticosteroids have been recently discontinued, they must have been stopped at
least 2 weeks prior to baseline. Decreases in steroid use due to AEs are allowed.

- Oral 5 ASA or sulfasalazine are allowed providing that the dose is stable for at
least 4 weeks prior to baseline.

- Crohn's disease related antibiotics are allowed providing that the dose is stable
for at least 4 weeks prior to baseline. If antibiotics are stopped prior to
baseline, they must be discontinued at least 4 days prior to baseline.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

1. Diagnosis of indeterminate colitis, microscopic colitis, ischemic colitis, infectious
colitis, radiation colitis, diverticular disease, ulcerative colitis (UC), or clinical
findings suggestive of UC.

2. Presence of active (draining) fistulae or intra abdominal or perineal abscesses.

3. Strictures with obstructive symptoms.

4. Short bowel syndrome.

5. History of bowel perforation requiring surgical intervention within the past 12
months.

6. Previous bowel surgery resulting in an existing stoma. Subjects who have a j pouch are
excluded, as a j pouch can result in a stoma.

7. History of bowel surgery within 6 months prior to baseline.

8. Subjects displaying clinical signs of fulminant colitis or toxic megacolon.

9. Subjects with primary sclerosing cholangitis.

10. Subjects with evidence of colonic adenomas, dysplasia or neoplasia.

11. Abnormal findings on the chest x ray film such as presence of tuberculosis (TB),
general infections, heart failure, or malignancy.

12. Any history of either untreated or inadequately treated latent or active TB infection,
current treatment for active or latent TB infection or evidence of currently active TB
by chest x ray, residing with or frequent close contact with individual(s) with active
TB.

13. Subjects receiving the following therapies within the time period described below or
expected to receive any of these therapies during the study period:

1. >9 mg/day of oral budesonide or >25 mg/day of prednisone or equivalent oral
systemic corticosteroid dose within 2 weeks prior to baseline.

2. IV, IM (parenteral), or topical (rectal) treatment of 5 ASA or corticosteroid
enemas/suppositories within 2 weeks prior to baseline.

3. Azathioprine, 6 mercaptopurine, or methotrexate within 2 weeks prior to baseline.

4. Anti TNF inhibitors (or biosimilars thereof) as described below:

- Infliximab within 8 weeks prior to baseline;

- Adalimumab within 8 weeks prior to baseline;

- Certolizumab within 8 weeks prior to baseline;

5. Anti integrin inhibitors (eg, vedolizumab) within 8 weeks prior to baseline.

6. Ustekinumab within 8 weeks prior to baseline.

7. Interferon therapy within 8 weeks prior to baseline.

8. Subjects with prior treatment with lymphocyte depleting agents/therapies within 1
year prior to baseline (eg, CamPath[alemtuzumab], alkylating agents [eg,
cyclophosphamide or chlorambucil], total lymphoid irradiation, etc).

9. Subjects who have received rituximab or other selective B lymphocyte depleting
agents within 1 year prior to baseline.

10. Subjects previously receiving leukocyte apheresis, including selective
lymphocyte, monocyte, or granulocyte apheresis, or plasma exchange within 6
months prior to baseline.

11. Other marketed immunosuppressants or biologics with immunomodulatory properties
within 3 months prior to baseline.

12. Subjects who have received other JAK inhibitors within 3 months prior to
baseline.

13. Subjects who have not responded to or have been intolerant of other JAK
inhibitors.

14. Other investigational procedures(s) or product(s), such as immunosuppressants
used in transplantation (eg, mycophenolate mofetil, cyclosporine, rapamycin, or
tacrolimus) or live (attenuated) vaccine within 30 days prior to baseline.
