Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy and tolerability of Menthacarin® in patients (= 18 years old) suffering from symptoms of IBS. ;Secondary Objective: Not Applicable;Primary end point(s): Change in abdominal pain (using an 11 point numeric rating scale (NRS)) at the time points of visit 4 in comparison to the time point of visit 2 (baseline), according to the assessment of the patient between Menthacarin (groups A1+A2) and placebo (groups B1+B2);Timepoint(s) of evaluation of this end point: Visits 2 and 4

Secondary

MeasureTime frame
Secondary end point(s): 1) Change in abdominal pain (using an 11 point numeric rating scale (NRS)), according to the assessment of the patient 2) Change in further abdominal symptoms, i.e. abdominal discomfort, abdominal cramping, abdominal fullness, and abdominal bloating (using an 11 point numeric rating scale (NRS)) 3) Change in Clinical Global Impression (Severity) (CGI-S) 4) Change in Clinical Global Impression (Change) (CGI-C) 5) Change in IBS global assessment of improvement (IBS-GAI) 6) IBS Quality of Life Questionnaire (IBS-QOL) 7) Change in Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) 8) Frequency of Spontaneous Bowel Movements (SBMs) 9) Change in bowel habits 10) Time point of first perceived abdominal symptom improvement after randomisation (assessed by the patient during the double-blind treatment phase) 11) Patient´s satisfaction with the randomized treatment using the Integrative Medicine Patient Satisfaction Scale (IMPSS) (assessed by the patient during the double-blind treatment phase) 12) Use of BUSCOPAN® PLUS film-coated tablets 13) Adverse events 14) Laboratory parameters 15) Vital signs 16) Global assessment of tolerability by investigator and patient;Timepoint(s) of evaluation of this end point: 1) NRS Change in abdominal pain - Visits 2, 3, 4, 5 & 6 2) NRS Change in abdominal symptoms - Visits 2, 3, 4, 5 & 6 3) CGI-S Visits 2, 3, 4, 5 & 6 4) CGI-C Visits 3, 4, 5 & 6 5) IBS-GAI Visits 3, 4, 5 & 6 6) IBS-QOL Visits 2, 4, 5 & 6 7) IBS-SSS Visits 2, 3, 4, 5 & 6 8) SBMs - Visits 2, 3, 4, 5 & 6 - daily assessment by Patient 9) Change in bowel habits - Visits 2, 3, 4, 5 & 6 10) Timepoint of first perceived - Visits 2 - 4 - daily assessment by patient 11) IMPSS - Visits 3, 4 12) Use of BUSCOPAN® PLUS - Visit 6 13) AEs - During the whole trial period 14) Labs - Visit 1, 4, 5 & 6 15) Vital signs - Visit 1, 2, 3, 4, 5 & 6 16) Global assessment of tolerability - Visits 3, 4, 5 & 6
