Brief Summary:

The purpose of study is to test the effects of an experimental medication GED-0301 (mongersen) in patients who have active Crohn's disease. The study will test GED-0301 compared to placebo for 52 weeks. The study treatment is blinded which means that patients and the study doctor will not know which treatment has been assigned. Patients in this study will be allowed treatment with stable doses of oral aminosalicylates, oral corticosteroids, immunosupressants and antibiotics for the treatment of Crohn's disease.

After 12 weeks in the study until the end of the study, patients who do not have an improvement in their Crohns disease symptoms will have the option to enter a long term active treatment study. Participants who discontinued the study anytime or completed the study at Week 52 were then observed for an additional 4 weeks.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The Percentage of Participants Who Achieved a Clinical Remission at Week 12 [ Time Frame: Week 12 ]
    Clinical remission is defined as a Crohn's Disease Activity Index (CDAI) score < 150. The Crohn's Disease Activity Index is used to quantify the signs and symptoms of Crohn's disease and the affect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.


Secondary Outcome Measures :
  1. Percentage of Participants Who Achieved Clinical Remission at Week 52 [ Time Frame: Week 52 ]
    Clinical remission is defined as a CDAI score < 150 and is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  2. Percentage of Participants With Endoscopic Response-50 Centrally Read at Week 52 [ Time Frame: Week 52 ]

    An endoscopic response-50 is defined as a reduction of at least 50% compared with baseline in simple endoscopic score for Crohn's Disease (SES-CD). The SES-CD assesses the size of mucosal ulcers, the extent of ulcerated surface, the extent of affected surface, and the presence and type of narrowings. Scores range from 0 to 60 with higher scores reflecting more severe disease. The SES-CD calculations include:

    • Ulcers scored as:

      0: no

      1. aphthous (0.1-0.5 cm)
      2. large (0.5-2 cm)
      3. very large (>2 cm)

    • Surface involved disease 0: 0%

      1. <50%
      2. 50-75%
      3. >75%

    Surface involved by ulcerations:

    0: 0%

    1. <10%
    2. 10-30%
    3. >30% - Narrowings:

    0: No

    1. Single, can be passed
    2. Multiple, can be passed
    3. Cannot be passed Grand Total = SES-CD score

  3. The Percentage of Participants Who Achieved a Clinical Response at Week 12 [ Time Frame: Week 12 ]
    A clinical response is defined as a CDAI score decrease from baseline ≥ 100 points. The CDAI is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  4. The Percentage of Participants Who Achieved a Clinical Response at Week 4 [ Time Frame: Week 4 ]
    A clinical response is defined as a decrease from baseline in CDAI ≥ 100 points. The Crohn's Disease Activity Index is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  5. The Percentage of Participants Who Achieved a Clinical Remission at Week 4 [ Time Frame: Week 4 ]
    A clinical remission is a CDAI score < 150. The Crohn's Disease Activity Index is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  6. The Percentage of Participants Who Achieved a Corticosteroid-Free Clinical Remission at Week 52 [ Time Frame: Week 52 ]
    The percentage of participants who were receiving oral corticosteroids for Crohn's disease, at baseline and achieved a clinical remission (CDAI score <150) at Week 52 without corticosteroids. The Crohn's Disease Activity Index is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  7. Percentage of Participants Who Achieved a Sustained Clinical Remission at Both Week 12 and 52 [ Time Frame: Weeks 12 and 52 ]
    For participants who achieved a sustained clinical remission at both week 12 and 52, the clinical remission is a CDAI score < 150. The Crohn's Disease Activity Index is used to quantify the signs and symptoms of Crohn's disease and the effect on patient's quality of life. It consists of 8 variables which include patient reported outcomes over a 7 day period and physician assessments which are scored numerically and weighted. Scores range from 0 to 600, with the most severe disease defined >450.

  8. Percentage of Participants With Endoscopic Response-25 Centrally Read at Week 12 [ Time Frame: Week 0, Week 12 ]

    An endoscopic response-25 is defined as a reduction of at least 25% compared with baseline in simple endoscopic score for Crohn's disease (SES-CD). The SES-CD assesses the size of mucosal ulcers, the extent of ulcerated surface, the extent of affected surface, and the presence and type of narrowings. Scores range from 0 to 60 with higher scores reflecting more severe disease. The SES-CD calculations include:

    • Ulcers scored as:

      0: no

      1. aphthous (0.1-0.5 cm)

    Endoscopic remission is defined as a simple endoscopic score for Crohn's disease (SES-CD) of ≤2 at the specified timeframe. The SES-CD assesses the size of mucosal ulcers, the extent of ulcerated surface, the extent of affected surface, and the presence and type of narrowings. Scores range from 0 to 60 with higher scores reflecting more severe disease. The SES-CD calculations include:

  10. The Number of Participants Who Experienced Treatment Emergent Adverse Events (TEAE) From Week 0 to Week 52 [ Time Frame: From the first day of GED-0301 until 28 days after the last dose of investigational product (IP); maximum treatment duration was 52.6 weeks ]
    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.

  11. The Number of Participants Who Discontinued IP Due to an Treatment Emergent Adverse Events [ Time Frame: From the first day of GED-0301 until 28 days after the last dose of IP; maximum treatment duration was 52.6 weeks ]
    A TEAE was defined as any AE occurring or worsening on or after the first dose 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.
