Endpoints

Primary endpoints

  • {"endpoint_text":"- Efficacy is assessed by a responder criterion, which is specified differently for patients with IBS-D and IBS-M. For both subgroups, a response of the abdominal pain is required (NRS pain): IBS-D patients: additional assessment of stool consistency stool consistency (Bristol Stool Form Scale). IBS-M patients: additionally an overall assessment of the change in bowel health using the PGI-I scale is also required.","definition_or_measurement_approach":"Response requires improvement in abdominal pain measured by NRS pain (numerical rating scale). For IBS-D patients additional assessment of stool consistency using the Bristol Stool Form Scale; for IBS-M patients additional overall change in bowel health using the Patient Global Impression of Improvement (PGI-I) scale."}
