1.5 at screening.
Must have a total SES-CD = 6 at screening, or the ileum segmental SESCD
= 4 at screening
Must have failed or experienced intolerance to at least one of the following: budesonide; systemic corticosteroids; immunosuppressants
(ie, azathioprine [AZA], 6-mercaptopurine
[6-MP], or methotrexate [MTX]); or biologics for the treatment of CD (ie,
infliximab, adalimumab, certolizumab or vedolizumab)
Are the trial subjects under 18? no

Exclusion criteria:
Diagnosis of ulcerative colitis (UC), indeterminate colitis, ischemic
colitis, microscopic colitis, radiation colitis or diverticular disease associated colitis
Local manifestations of CD such as abscesses, short bowel syndrome; or other disease complications for which surgery might be indicated or
could confound the evaluation of efficacy
Strictures with prestenotic dilatation, requiring procedural intervention, or with obstructive symptoms. In addition, colonic strictures that are not
passable with an adult colonoscope, or strictures in the ileum or ileocecal valve that are fibrotic in nature, will be excluded.
Any intestinal resection within 6 months or any intra-abdominal surgery within 3 months prior to the Screening Visit
Prior treatment with mycophenolic acid, tacrolimus, sirolimus,

corticosteroid enemas or suppositories within 2 weeks prior to the
Screening Visit
Use of bile acid sequestrants, (eg, cholestyramine) within 3 weeks prior
to the Screening Visit
Prior treatment with biologics for the treatment of CD (approved or
investigational), other than infliximab, adalimumab, certolizumab or
vedolizumab
Prior treatment with more than 3 biologics for the treatment of CD (ie,
infliximab, adalimumab, certolizumab or vedolizumab). Treatment
with a biologic within 8 weeks prior to the Screening Visit, or 5

Primary Outcome(s)

Main Objective: To evaluate the efficacy of GED-0301 compared with placebo on clinical activity at 12 Weeks, in subjects with active Crohn’s disease (CD).

Primary end point(s): Efficacy as clinical remision: the proportion of subjects achieving clinical remission defined as a (CDAI) score < 150 at Week 12

Secondary Objective: To evaluate the efficacy of GED-0301 compared with placebo on endoscopic outcomes, as measured by the Simple Endoscopic Score for Crohn's Disease (SES-CD) in subjects with active CD;
To evaluate the long term efficacy of GED-0301 compared with placebo on clinical activity in subjects with active CD
To evaluate the efficacy of GED-0301 compared with placebo on corticosteroid-free clinical remission in subjects with active CD;
To evaluate the long-term efficacy of GED-0301 compared with placebo on clinical activity and endoscopic outcomes in subjects with active CD;
To evaluate the safety and tolerability of GED-0301 in subjects with active CD.

Timepoint(s) of evaluation of this end point: Week 12

Secondary Outcome(s)

Secondary end point(s): Proportion of subjects achieving:
- clinical remission, defined as a CDAI score < 150, at Week 52.
- endoscopic response-50 (ER-50), defined as a reduction of at least
50% in SES-CD compared with baseline, at Week 52.
Proportion of subjects with clinical response:
- defined as a decrease from baseline in CDAI = 100 points, at Week 12.
- defined as a decrease from baseline in CDAI = 100 points, at Week 4.
Proportion of subjects:
- achieving clinical remission, defined as a CDAI score < 150, at Week 4.
- who achieve corticosteroid-free clinical remission (CDAI <150) at
Week 52 among subjects receiving oral corticosteroids for CD at
baseline.
- achieving sustained clinical remission, defined as a CDAI score < 150,at both Week 12 and Week 52.
- with endoscopic response-25 (ER-25), defined as a reduction of at least
25% in the SES-CD compared with baseline, at Week 12.
- endoscopic remission, defined as SES-CD = 2, at Week 52.
Type, frequency, severity, seriousness, and relationship of AEs to IP.
Number of subjects who discontinue investigational product (IP) due to
any AE.
Clinically significant changes in vital signs, ECG and/or laboratory
findings.
