Phase 3
Terminated
Conditions
Crohn's Disease
Interventions
Other: Placebo
Registration Number
NCT02641392
Lead Sponsor
Celgene
Brief Summary

The purpose of this study is to assess long-term safety data of GED-0301 for a period of up to 208 weeks in adult subjects (i.e., ≥ 18 years of age) who participated in the core Phase 3 GED-0301-CD-002 and GED-0301-CD-003 studies and adolescent subjects (i.e., 12 to 17 years of age) who participated in the core Phase 3 GED-0301-CD-003 study. Although all subjects will receive active treatment, this study is double-blinded for the entire 208 weeks for the purpose of preserving the blind of the subject's treatment allocation in the initial, core Phase 3 GED-0301 study.

The GED-0301-CD-003 trial was not initiated; see detailed description.

Detailed Description

This is a long-term active treatment study in patients with Crohn's disease (CD). Subjects who met the early escape criteria in Study GED-0301-CD-002, or subjects who completed Study GED-0301-002 or GED-0301-003, may be eligible for this study. Primary objective is to assess long-term safety of GED 0301. Additional efficacy and patient reported outcomes will be explored.

There are 5 possible treatment groups for GED-0301-CD-002 Subjects (Groups 1-5). There are 3 possible treatment groups for GED-0301-CD-003 subjects (Groups 1-3). Treatment is assigned based on clinical improvement achieved or not achieved from the core GED-0301 study.

1. continuous GED-0301 160 mg once daily for 12 weeks, followed by alternating placebo once daily for 4 weeks with GED-0301 160 mg once daily for 4 weeks, through Week 208;

2. alternating GED-0301 160 mg once daily for 4 weeks with placebo once daily for 4 weeks, through Week 208;

3. alternating placebo once daily for 4 weeks with GED-0301 160 mg once daily for 4 weeks, through Week 208;

4. continuous GED-0301 40 mg once daily through Week 208;

5. alternating placebo once daily for 4 weeks, followed by GED-0301 40 mg once daily for 4 weeks, through Week 208.

The GED-0301-CD-003 trial was not initiated; the GED-0301 program was terminated; no safety findings were noted.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Treatment Emergent Adverse Events From Week 0 to Week 208From the first day of GED-0301 until 28 days after the last dose of IP; maximum treatment duration was 16.1 weeks in the GED-0301 40 mg Alt dose; 16.3 weeks in the GED 40 mg continuous dose and 56.1 weeks in the GED-0301 160 mg Alt dose

A TEAE was defined as any adverse event (AE) occurring or worsening on or after the first treatment of GED-0301 and up to 28 days after the last GED- 0301 dose or the last follow-up date, whichever occurred earlier. A serious AE = any AE which results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; constitutes an important medical event. The severity of AEs was assessed by the investigator and based on the following scale; Mild = asymptomatic or mild symptoms; clinical or diagnostic observations only; Moderate = Symptoms cause moderate discomfort; Severe (could be non-serious or serious) = symptoms causing severe discomfort/pain.
