Efficacy and Safety of Chinese Medicine JCM-16021 for Diarrhea-predominant Irritable Bowel Syndrome: a Multicenter, Randomized, Double-blind, Placebo Controlled Clinical Trial

This is a multicenter, randomized, double-blind, placebo controlled clinical trial, in order to evaluate the efficacy and safety of Chinese Medicine JCM-16021 for diarrhea-predominant irritable bowel syndrome. All patients will be evaluated for study eligibility at Visits 1 (baseline) and 2 (2 weeks). On visit 2, patients who meet the criteria will be randomly assigned to receive 8-week treatment of either JCM-16021 Granules or JCM-16021 placebo Granules. The investigators, research assistants and participants are not aware of the treatment assignments throughout the study. Treatment codes will only be broken after the completion of study. The assessments at Visit 3 (4-week post treatment) and at visit 4 (end of 8-week treatment) are used to measure treatment response (i.e. changes from baseline). Assessment at visit 5 (end of 8-week follow up) is to determine any sustained response to treatment. All the visits will be carried out in HKBU and CUHK clinics.

AbstractBackgroundIrritable bowel syndrome (IBS) is a common gastrointestinal functional disease. Adults with IBS may experience abdominal pain, change of bowel habits, and abnormal stool form without organic disease. IBS can seriously affect their work productivity and quality of life, especially diarrhea-predominant irritable bowel syndrome (IBS-D). The Chinese medicine JCM-16021 has been shown to be potentially effective in improving the symptoms of IBS-D based on a small scale clinical trial. Hence, a large scale clinical study is designed to further evaluate the efficacy and safety of the Chinese medicine JCM-16021 for IBS-D with traditional Chinese medicine (TCM) pattern of Liver Stagnation and Spleen Deficiency (LSSD).MethodsThis study is a multi-center, randomized, double-blind, placebo-controlled clinical trial. 392 eligible participants will be enrolled with 2-week run-in, 8-week treatment and 8-week follow-up. After run-in period, participants will be randomized to receive either the Chinese medicine JCM-16021 or placebo for 8 weeks, and will have post-treatment follow up for another 8 weeks. The primary outcome is the improvement rate on the global assessment of improvement (GAI) at week 10. The secondary outcomes consist of changes of IBS-D symptoms, TCM pattern improvement, IBS-Quality of Life (IBS-QoL), IBS-Symptom Severity Score (IBS-SSS), safety, etc.ResultsA standard protocol has been developed for the study. The protocol will provided a detailed procedure to conduct a clinical trial and verify if the Chinese medicine JCM-16021 would significantly improve the overall symptoms of IBS-D with LSSD pattern of TCM by relieving abdominal pain, reducing stool frequency, improving the stool consistency and improving quality of life. The consolidated evidence from the study can shed light on the treatment of IBS-D with Chinese medicine.ConclusionThe protocol will provide details for investigators about the study following SPIRIT Statement. High-quality evidence on the efficacy and safety of Chinese medicine JCM-16021 for IBS-D will be provided through strict compliance with the protocol.Trial registration: ClinicalTrial.gov identifier: NCT03457324.

The present study aimed to investigate the analgesic effect of JCM-16021, a revised traditional Chinese herbal formula, on postinflammatory irritable bowel syndrome (PI-IBS) in rats. The trinitrobenzene sulfonic (TNBS) acid-induced PI-IBS model rats were orally administrated with different doses of JCM-16021 (1.2, 2.4, and 4.8 g/kg/d) for 14 consecutive days. The results showed that JCM-16021 treatment dose-dependently attenuated visceral hyperalgesia in PI-IBS rats. Further, the colonic enterochromaffin (EC) cell number, serotonin (5-HT) content, tryptophan hydroxylase expression, and mechanical-stimuli-induced 5-HT release were significantly ameliorated. Moreover, the decreased levels of mucosal cytokines in PI-IBS, especially the helper T-cell type 1- (Th1-) related cytokine TNF-α, were also elevated after JCM-16021 treatment. These data demonstrate that the analgesic effect of JCM-16021 on TNBS-induced PI-IBS rats may be medicated via reducing colonic EC cell hyperplasia and 5-HT availability.

AIMTo investigate the pharmacological effect of JCM-16021, a Chinese herbal formula, and its underlying mechanisms.METHODSJCM-16021 is composed of seven herbal plant materials. All raw materials of the formula were examined according to the quality control criteria listed in the Chinese Pharmacopeia (2005). In a neonatal maternal separation (NMS) model, male Sprague-Dawley rats were submitted to daily maternal separation from postnatal day 2 to day 14, or no specific handling (NH). Starting from postnatal day 60, rats were administered JCM-16021 (2, 4, 8 g/kg per day) orally twice a day for 28 d. Pain threshold pressure and electromyographic activities of external oblique muscles in response to colorectal distention recorded with a Power Lab System (AD Instruments International), were tested as pain indices. Changes in serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) concentrations in the colon of rats were analyzed; the enterochromaffin cell numbers and serotonin transporter in the colon of rats were also evaluated with an immunohistochemistry method.RESULTSNMS treatment significantly reduced pain threshold pressure (37.4 +/- 1.4 mmHg), as compared to that of NH rats (57.7 +/- 1.9 mmHg, P < 0.05). After JCM-16021 treatment, the pain threshold pressure significantly increased when compared to that before treatment (34.2 +/- 0.9 mmHg vs 52.8 +/- 2.3 mmHg in the high dose group, 40.2 +/- 1.6 mmHg vs 46.5 +/- 1.3 mmHg in the middle dose group, and 39.3 +/- 0.7 mmHg vs 46.5 +/- 1.6 mmHg in the low dose group, P < 0.05). Also JCM-16021 significantly and dose-dependently decreased electromyographic activity to the graded colorectal distension (CRD), (the mean DeltaAUC values were: 0.17 +/- 0.03, 0.53 +/- 0.15, 1.06 +/- 0.18, 1.22 +/- 0.24 in the high dose group; 0.23 +/- 0.04, 0.68 +/- 0.17, 1.27 +/- 0.26, 1.8 +/- 0.3 in the middle dose group; and 0.29 +/- 0.06, 0.8 +/- 0.16, 1.53 +/- 0.24, 2.1 +/- 0.21 in the low dose group for the pressures 20, 40, 60, 80 mmHg), as compared to the NMS vehicle group. The mean DeltaAUC values were: 0.57 +/- 0.12, 1.33 +/- 0.18, 2.57 +/- 0.37, 3.08 +/- 0.37 for the pressures 20, 40, 60, 80 mmHg (P < 0.05). JCM-16021 treatment significantly reduced the 5-HT concentrations (from high, middle and low dosage groups: 60.25 +/- 5.98 ng/100 mg, 60.32 +/- 4.22 ng/100 mg, 73.31 +/- 7.65 ng/100 mg), as compared to the NMS vehicle groups (93.11 +/- 9.85 ng/100 mg, P < 0.05); and increased the 5-HIAA concentrations (after treatment, from high, middle and low dosage groups: 54.24 +/- 3.27 ng/100 mg, 50.34 +/- 1.26 ng/100 mg, 51.37 +/- 2.13 ng/100 mg) when compared to that in the NMS vehicle group (51.75 +/- 1.98 ng/100 mg, P < 0.05); but did not change the enterochromaffin cell numbers in the colon of rats. In addition, NMS rats had higher SERT expression (n = 10) than NH rats (n = 8, P < 0.05). JCM-16021 treatment significantly decreased SERT expression when compared to the NMS group (P < 0.01-0.001).CONCLUSIONJCM-16021 can attenuate visceral hypersensitivity, and this analgesic effect may be mediated through the serotonin signaling pathway in the colon of rats.
