- To explore the effect of mongersen (GED-0301) 160 mg QD on endoscopic outcomes, as measured by the Simple Endoscopic Score for Crohn's Disease (SES-CD) in subjects with active CD
- To evaluate the safety and tolerability of mongersen (GED-0301) 160 mg QD in subjects
with active CD

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

Secondary Outcome(s)

Secondary end point(s): PD: Change from baseline in the messenger RNA (mRNA) expression of inflammatory cytokines such as, but not limited to, interleukin (IL)-10, IL-25, chemokine (C-Cmotif) ligand 20 (CCL20) and tumor necrosis factor alpha(TNF-a) in the intestinal mucosa at Week 12, from biopsy samples during ileocolonoscopy
Efficacy:
1)The proportion of subjects achieving clinical remission, defined as a Crohn’s Disease Activity Index (CDAI) score < 150, at Weeks 4, 8, and 12
2) Change from baseline in the Simple Endoscopic Score for Crohn’s Disease (SES-CD) at Week 12
3) The evaluation of safety and tolerability of mongersen (GED-0301), assessed by the type, frequency and severity of adverse events, and its relationship to investigational product (IP), discontinuation due to adverse events, and
clinically significant changes in lectrocardiograms
(ECGs), vital signs, and/or laboratory findings

Timepoint(s) of evaluation of this end point: PD: Week 12
Efficacy: 1) Weeks 4, 8,12; 2)Week 12; 3) Through Week 52 and 4 weeks postdose
