Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants Who Were Composite Responders Based on Improvements From Baseline in Daily Worst Abdominal Pain and Daily Stool Consistency Scores [ Time Frame: Up to 12 weeks ]
    Composite responders were defined as participants who met the daily response criteria for at least 50% of the days with diary entries during the interval of interest. A participant must had met both of the following criteria on a given day to be a daily responder: 1) Daily pain response: worst abdominal pain scores in the past 24 hours improved by ≥30% compared to baseline (average of daily worst abdominal pain the week prior to randomization). 2) Daily stool consistency response: Bristol Stool Scale (BSS) score <5 (ie, score of 1, 2, 3, or 4) or the absence of a bowel movement if accompanied by ≥30% improvement in worst abdominal pain compared to baseline pain. Bristol stool scale was defined as 7-point Scale in which a score of 1 = separate hard lumps, 2 = sausage shaped but lumpy, 3 = sausage-like with cracks on the surface, 4 = sausage-like but smooth and soft, 5 = soft blobs with clear cut edges, 6 = fluffy pieces with ragged edges, and 7 = watery with no solid pieces.


Secondary Outcome Measures :
  1. Percentage of Participants Who Were Composite Responders Based on Improvements From Baseline in Daily Worst Abdominal Pain and Daily Stool Consistency Scores [ Time Frame: Up to 26 weeks ]
    Composite responders were defined as participants who met the daily response criteria for at least 50% of the days with diary entries during the interval of interest. A participant must had met both of the following criteria on a given day to be a daily responder: 1) Daily pain response: worst abdominal pain scores in the past 24 hours improved by ≥30% compared to baseline (average of daily worst abdominal pain the week prior to randomization). 2) Daily stool consistency response: Bristol Stool Scale (BSS) score <5 (ie, score of 1, 2, 3, or 4) or the absence of a bowel movement if accompanied by ≥30% improvement in worst abdominal pain compared to baseline pain. Bristol stool scale was defined as 7-point Scale in which a score of 1 = separate hard lumps, 2 = sausage shaped but lumpy, 3 = sausage-like with cracks on the surface, 4 = sausage-like but smooth and soft, 5 = soft blobs with clear cut edges, 6 = fluffy pieces with ragged edges, and 7 = watery with no solid pieces.

  2. Percentage of Participants Who Were Pain Responders In Daily Worst Abdominal Pain Scores by Intervals [ Time Frame: 12-week interval (Weeks 1-12), 26-week interval (Weeks 1-26), and 4-week interval (Weeks 1-4, 5-8, 9-12, 13-16, 17-20, and 21-24) ]
    Pain responders were defined as participants who met the daily pain response criteria (ie, the worst abdominal pain score in the past 24 hours improved by ≥30% compared to baseline) for at least 50% of days with diary entries during each interval. A participant must have had a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over the 12-week interval, and a minimum of 110 days of diary entries over the 26-week interval to be a responder.

  3. Percentage of Participants Who Were Responders In Daily Stool Consistency Scores by Intervals [ Time Frame: 12-week interval (Weeks 1-12), 26-week interval (Weeks 1-26), and 4-week interval (Weeks 1-4, 5-8, 9-12, 13-16, 17-20, and 21-24) ]
    Stool consistency responders: Participants who met daily stool consistency response criterion (ie,score of 1, 2, 3, or 4 or absence of bowel movement if accompanied by ≥30% improvement in worst abdominal pain compared to baseline pain) for at least 50% of days with diary entries during each interval. BSS was defined as 7-point Scale in which score of 1= separate hard lumps, 2= sausage shaped but lumpy, 3= sausage-like with cracks on the surface, 4= sausage-like but smooth and soft, 5= soft blobs with clear cut edges, 6= fluffy pieces with ragged edges, and 7= watery with no solid pieces. A participant must have had a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over 12-week interval, and a minimum of 110 days of diary entries over 26-week interval to be a responder.

  4. Percentage of Participants Who Were Responders In Irritable Bowel Syndrome, Diarrhea Predominant (IBS-d) Global Symptom Scale by Intervals [ Time Frame: 12-week interval (Weeks 1-12), 26-week interval (Weeks 1-26), and 4-week interval (Weeks 1-4, 5-8, 9-12, 13-16, 17-20, and 21-24) ]
    IBS-d global symptom responders were defined as those participants who met the daily IBS-d global symptom response criteria (ie, IBS-d global symptom score of 0 [none] or 1 [mild]; or a daily IBS-d global symptom score improved by ≥2.0 compared to the baseline average) for at least 50% of days with diary entries during each interval. IBS-d Global Symptom Scale was a 5-point scale, score ranging from 0 to 4. 0= no symptoms, 1= mild symptoms, 2= moderate symptoms, 3= severe symptoms and 4 = very severe symptoms. A participant must have had a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over the 12-week interval, and a minimum of 110 days of diary entries over the 26-week interval to be a responder.

  5. Percentage of Participants Who Were Responders to the Irritable Bowel Syndrome Quality of Life Measure (IBS-QoL) Scale [ Time Frame: Weeks 4, 8, 12, 18, 26 and 30 (End of Treatment [EOT]) ]
    IBS-QoL responders were defined as participants who achieved at least a 14-point improvement in IBS-QoL total score from baseline to the applicable visit. The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100-point (0= worst; 100=better) scale for ease of interpretation.

  6. Percentage of Participants With Irritable Bowel Syndrome - Adequate Relief (IBS-AR) Scale [ Time Frame: 12-week interval (Weeks 1-12) and 26-week interval (Weeks 1-26) ]
    Adequate relief of IBS symptoms was assessed once weekly by participants answering the IBS-AR item in the electronic diary. IBS-AR responders were defined as participants with a weekly response of "Yes" to adequate relief of their IBS symptoms for at least 50% of the total weeks during the interval. A participant must have had a positive response on ≥6 weeks for the 12-week interval and ≥13 weeks for the 26-week interval, regardless of diary compliance, to be a responder.

  7. Change From Baseline in Daily Abdominal Discomfort Scores [ Time Frame: Baseline, Weeks 4, 12 and 26 ]
    Symptoms of abdominal discomfort were recorded on a 0 to 10 scale, where 0 corresponded to no discomfort and 10 corresponded to worst imaginable discomfort. A negative change from Baseline indicates the discomfort decreased.

  8. Change From Baseline in Daily Abdominal Bloating Scores [ Time Frame: Baseline, Weeks 4, 12 and 26 ]
    Symptoms of abdominal bloating were recorded on a 0 to 10 scale, where 0 corresponded to no bloating and 10 corresponded to worst imaginable bloating. A negative change from Baseline indicates the bloating decreased.

  9. Number of Bowel Movements Per Day [ Time Frame: Weeks 4, 12 and 26 ]
    Participants recorded the number of bowel movements over 24 hours daily throughout the treatment.

  10. Number of Bowel Incontinence Episodes [ Time Frame: Weeks 4, 12 and 26 ]
    Participants recorded the number of incontinence episodes over 24 hours daily throughout the treatment.

  11. Number of Bowel Incontinence Free Days [ Time Frame: Weeks 4, 12 and 26 ]
    An incontinence free day was one where the participant reports zero incontinence episodes. The number of incontinence free days for a participant was assessed each week based on the number of reported days.

  12. Number of Urgency Episodes Per Day [ Time Frame: Weeks 4, 12 and 26 ]
    Participants recorded the number of urgency episodes over 24 hours daily throughout the treatment.

  13. Change From Baseline in IBS-QoL Total Scores [ Time Frame: Baseline, Weeks 4, 8, 12, 18, 26 and 30/EOT ]
    The IBS-QoL consists of 34 items each with a 5-point response scale, where 1 generally represents better responses on items and 5 represents worse responses. The individual responses to the answered items were summed and standardized for a total score and then transformed to a 0- to 100- point scale (0=worst; 100=better) for ease of interpretation. A positive change from Baseline indicates that quality of life improved.
