Treatment and study plan

Eluxadoline

Drug

Eluxadoline 100 mg oral tablets BID with food.

Primary outcomes

  1. Change From Baseline in Average Bristol Stool Form Scale (BSFS) Score Over 4 Weeks of Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    Stool consistency was assessed using the BSFS where: 1=Separate hard lumps like nuts to 7=Watery. The score was recorded by the participant in an electronic diary (e-diary). The score for each day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  2. Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)

    Time frame: Baseline (Day 1) to Week 4

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A TEAE is an AE that occurs or worsens after receiving investigational study drug.

  3. Number of Participants Who Experienced Potentially Clinically Significant Change in Laboratory Tests

    Time frame: Baseline (Day 1) to Week 4

    Laboratory tests included tests of Clinical Chemistry, Hematology, and Urinalysis. The investigator determined if the result was potentially clinically significant.

  4. Number of Participants Who Experienced Potentially Clinically Significant Change in Vital Signs

    Time frame: Baseline (Day 1) to Week 4

    Vital signs assessments included: pulse, respiratory rate, and blood pressure (systolic and diastolic). The investigator determined if the result was potentially clinically significant.

  5. Number of Participants Who Experienced Clinically Significant Change From Baseline in General Physical Condition as Measured Through General Physical Exam

    Time frame: Baseline (Day 1) to Week 4

    General Physical Examination consisted of a full review of body systems excluding pelvic and rectal exams. The investigator determined if the result was clinically significant.

Secondary outcomes

  1. Change From Baseline in the 4-week Average of Daily Bowel Movement Frequency During the Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    Bowel movements were recorded by the participant in an electronic diary (e-diary). The number of bowel movements per day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  2. Change From Baseline in the 4-week Average of Daily Worst Abdominal Pain Scores During the Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    The participant recorded their worst abdominal pain score in the past 24 hours each day in an e-diary where: 0=no pain to 10=worst imaginable pain. The score each day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  3. Change From Baseline in the 4-week Average of Daily Bloating Scores During the Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    The participant recorded their bloating score in the past 24 hours each day in an e-diary where: 0=no bloating to 10=worst imaginable bloating. The score each day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  4. Change From Baseline in the 4-week Average Number of Daily Urgent Bowel Movements During the Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    The participant recorded the number of urgent bowel movements in the past 24 hours each day in an e-diary. The number of urgent bowel movements per day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  5. Percentage of Participants With Any Fecal Incontinence During the Treatment Period

    Time frame: Baseline (Day 1) to Week 4

    The participant recorded the number of fecal incontinences in the past 24 hours each day in an e-diary. Fecal incontinence is the inability to control the passage of gas or stools. The number of fecal incontinences per day was averaged over the 4-week period. A negative change from Baseline indicates improvement.

  6. Change From Baseline in Irritable Bowel Syndrome Quality of Life (IBS-QOL) Total Score at the End of the Treatment Period

    Time frame: Baseline (Day1) to End of Treatment (Up to Week 4)

    IBS-QOL is composed of 34 items about how the symptoms of IBS are impacting the participant's life scored on a 1 to 5 scale, where lower item scores indicate greater quality of life. 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 improved quality of life.

  7. Change From Baseline in Fasting Serum 7α-hydroxy-4-cholesten-3-one (7αC4) Levels at the End of the Treatment Period

    Time frame: Baseline (Day 1) to End of Treatment (Up to Week 4)

    Participants fasted for at least 8 hours prior to the test. Fasting serum 7αC4 level was measured at Baseline and End of Treatment to determine whether any changes occurred following treatment with eluxadoline. The negative change from Baseline indicates improvement.

  8. Cmax: Maximum Concentration for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  9. Cmin: Minimum Concentration for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  10. AUC: Area Under the Concentration-time Curve During the Dosing Interval for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  11. Tmax: Time to Cmax for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  12. t1/2: Half-Life for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  13. CL/F: Apparent Total Clearance of the Drug From Plasma After Oral Administration for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2

  14. Vc/F: Apparent Volume of Distribution for Eluxadoline

    Time frame: Predose and at the intervals 1-2, 3-4 and 5-8 hours postdose at Week 2
