Trial Outcomes & Findings for Efficacy and Safety of Mebeverine + Simethicone in Patients With Functional Bowel Disorders (NCT NCT05175131)

NCT ID: NCT05175131

Last Updated: 2025-09-16

Results Overview

The baseline abdominal pain and bloating/flatulence intensity was determined as the average of the Numeric rating scale (NRS-11) daily assessment during 7 days before randomization. The Week 4 assessment was the average from last 7 days of the corresponding week. The scale is a horizontal 10 cm line with the numbers from 0 to 10 located on it, where 0 is "no pain/bloating", 10 is "most severe pain/bloating you can imagine".

PRIMARY outcome

Timeframe: 4 weeks

Population: 465 subjects were allocated to treatment. 2 subjects had only a baseline assessment of the efficacy parameters and were excluded from the full analysis sample. Therefore, 463 subjects were included in the Full Analysis Sample (FAS)

The baseline abdominal pain and bloating/flatulence intensity was determined as the average of the Numeric rating scale (NRS-11) daily assessment during 7 days before randomization. The Week 4 assessment was the average from last 7 days of the corresponding week. The scale is a horizontal 10 cm line with the numbers from 0 to 10 located on it, where 0 is "no pain/bloating", 10 is "most severe pain/bloating you can imagine".

SECONDARY outcome

Timeframe: 4 weeks

The data from last week of screening and run-in period was used for baseline assessment of number of days of drotaverin intake. Week 1, Week 2, Week3 and Week 4 assessments were the data from the last 7 days of the corresponding week.

SECONDARY outcome

Timeframe: 4 weeks

Patients were asked to evaluate the quality of life using the Irritable bowel syndrome quality of life (IBSQOL) questionnaire at baseline at Visit 2 (Week 0) and at the end of the study treatment at Visit 3 (Week 4). The individual responses to the 34 items were summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life.
