August 10, 2018 updated by: Celgene

A Phase 2, Open-label Study to Explore the Pharmacodynamic and Clinical Effects of Mongersen (GED-0301) in Subjects With Active Crohn's Disease

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: GED-0301 Induction (160mg) followed by intermittent 160 mg
GED-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
Drug: GED-0301
During Induction period patient will receive mongersen 160 mg daily for 12 weeks. This study also offers subjects the option to continue with maintenance treatment at the discretion of the Investigator, beginning after the Week 12 Visit with alternating no IP for 4 weeks, followed by mongersen (GED-0301) 160 mg QD for 4 weeks, up through the Week 52 Visit during the Maintenance Period. At Week 52, subjects who have achieved an endoscopic improvement of >50% from baseline based on the SES-CD, as assessed by the central reader, and clinical improvement (HBI <7), will have the option to continue receiving treatment for an additional year, up through Year 2 (ie, the Week 100 Visit).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline of Smad7 (Mothers Against Decapentaplegic homolog 7) expression in the intestinal mucosa
Time Frame: Baseline and Week 12
Smad7 is a protein important in cell interactions and stands for "Mothers against decapentaplegic homolog 7" protein
Baseline and Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline in messenger ribonucleic acid (mRNA) expression of inflammatory cytokines
Time Frame: Baseline 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
Baseline and Week 12
The proportion of subjects achieving clinical remission, defined as a Crohn's Disease Activity Index (CDAI) score < 150, at Weeks 4, 8, and 12
Time Frame: Up to week 12
The CDAI is a measure of disease activity in patients with Crohn's Disease.
Up to week 12
Change from baseline in the Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12 and 52
Time Frame: Week 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
Week 12 and week 52
Number of Adverse Events
Time Frame: Up 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
Up to Week 56
