Pharmacodynamic and Clinical Outcome Study of Mongersen in Patients With Crohn's Disease

Phase 2
Terminated
Conditions
Crohn's Disease
Interventions
Registration Number
NCT02685683
Lead Sponsor
Celgene
Brief Summary

This study is designed to explore mechanism of action of mongersen (GED-0301) 160 mg once daily in patients with active Crohn's Disease

Detailed Description

Subjects will be screened to provide 20 enrolled subjects who complete 12 weeks of mongersen (GED-0301) 160 mg QD treatment as open-label therapy.

The study will consist of 4 periods:

* Screening Period - up to 4 weeks

* Induction Period - 12 weeks (Week 0 Visit through Week 12 Visit)

* Maintenance Period - 88 weeks (after Week 12 Visit through Week 100 Visit)

* Follow-up Period - 4 weeks (ie, no IP taken)

Subjects who prematurely discontinue treatment from this study prior to Week 100 will have an Early Termination Visit and also enter the 4-week Follow-up Period.

At the Screening Visit, all subjects who meet the entrance criteria will be eligible to enter the study. The number of subjects with previous exposure to Tumor Necrosis Factor-Alpha (TNF-α) blockers is targeted to be approximately 40% (ie, approximately 8 subjects).

GroupInterventionDescription
GED-0301 Induction (160mg) followed by intermittent 160 mgGED-0301GED-0301 160 mg "by mouth" (PO) daily (QD) for 12 weeks, followed by alternating GED 0301 160 mg QD for 4 weeks and no IP for 4 week, up to Week 100
Primary Outcome Measures
NameTimeMethod
Change from baseline of Smad7 (Mothers Against Decapentaplegic homolog 7) expression in the intestinal mucosaBaseline and Week 12

Smad7 is a protein important in cell interactions and stands for "Mothers against decapentaplegic homolog 7" protein

Secondary Outcome Measures
NameTimeMethod
The proportion of subjects achieving clinical remission, defined as a Crohn's Disease Activity Index (CDAI) score < 150, at Weeks 4, 8, and 12Up to week 12

The CDAI is a measure of disease activity in patients with Crohn's Disease.

Change from baseline in messenger ribonucleic acid (mRNA) expression of inflammatory cytokinesBaseline and Week 12

Change from baseline in the mRNA expression of inflammatory cytokines such as, but not limited to, interleukin (IL)-10, IL-25, chemokine (C-C motif) ligand 20 (CCL20) and tumor necrosis factor alpha (TNF-α) in the intestinal mucosa at Week 12, from biopsy samples during ileocolonoscopy

Change from baseline in the Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12 and 52Week 12 and week 52

The SES-CD is a measure that indicates mucosal inflammation in the end part of the ileum (or small intestine) and colon (or large intestine) in patients with Crohn's Disease

Number of Adverse EventsUp to Week 56

The evaluation of safety and tolerability of 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 electrocardiograms (ECGs), vital signs, and/or laboratory findings
