Clinical Efficacy and Safety of Jingfang Granules in Treating Diarrhea-Predominant Irritable Bowel Syndrome With Cold-Dampness Disturbing Spleen Syndrome
30. Juni 2026 aktualisiert von: Nanjing First Hospital, Nanjing Medical University
This prospective, open-label, randomized controlled clinical trial aims to evaluate the clinical efficacy and safety of Jingfang Granules in the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) with cold-dampness encumbering the spleen syndrome, and to explore its potential mechanisms of action.
A total of 106 patients with IBS-D of cold-dampness encumbering the spleen syndrome are planned to be enrolled and randomly assigned to the experimental group and the control group, with 53 patients in each group.
The treatment will last for 4 weeks, followed by a 12-week follow-up period.
The primary outcome measure is the IBS Severity Scoring System (IBS-SSS).
Secondary outcomes include the Traditional Chinese Medicine (TCM) syndrome score, the Bristol Stool Form Scale, patient-reported outcome (PRO) scales, the IBS Quality of Life (IBS-QOL) questionnaire, recurrence rate, and others.
Exploratory measures, such as immune-inflammatory cytokines and biomarkers related to intestinal mucosal barrier function, will also be observed.

|
Irritable Bowel Syndrome Severity Scoring System scale
Zeitfenster: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
This scale is an internationally recognized assessment tool for IBS symptom severity, with a total score ranging from 0 to 500.
Lower scores indicate milder symptoms.

Biomarker
Zeitfenster: before treatment, after 4 weeks of treatment
|
Measure the levels of biomarkers such as IL-1β, IFN-γ, IL-6, TNF-α, diamine oxidase, D-lactic acid, and endotoxin to explore the mechanism of action.

Evaluation of the efficacy of Chinese medicine evidence
Zeitfenster: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
A quantitative scale formulated based on the Guiding Principles for Clinical Research of New Chinese Medicines and the diagnostic criteria for cold-dampness encumbering the spleen pattern, with graded scoring for primary and secondary symptoms.
