Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the trial is to assess the efficacy of repeated twice daily doses of Blautix™ >1E10 MPN for 8 weeks in adult subjects with either IBS-C or IBS-D ;Secondary Objective: The secondary objectives of the trial is to assess the safety of repeated twice daily doses of Blautix™ >1E10MPN for 8 weeks in adult subjects with either IBS-C or IBS-D;Primary end point(s): The primary efficacy endpoint is whether the subject is an overall responder. A subject is an 'overall responder' if they have reported an improvement in their weekly (Cohort specific) symptoms (abdominal pain intensity and stool frequency or consistency) for > 50% of the treatment period (in this case 4 out of 8 weeks).;Timepoint(s) of evaluation of this end point: On-going throughout the 8 week duration of the study | — |
