简要总结

This study aims to determine 1) the efficacy and safety of MZRW in IBS-C patients; 2) whether and how gut microbiota mediates the ameliorative effects of MZRW in FC and IBS-C spectrum; and 3) whether MZRW will take effect on patients through modulating gut dysbiosis.

入选标准

  • FC subjects:
  • Meet the diagnostic criteria for functional constipation based on Rome IV criteria;
  • Aged 18 to 65 years;
  • Signed an informed Consent Form (ICF);
  • Complete spontaneous bowel movement (CSBM) <= 2 times/week (CSBM is defined by feeling of complete passage of stool and without the use of laxatives or enemas within 24 hours);
  • Meet protocol-defined e-Diary completion compliance and agree to refrain from making any new, major life-style changes that may affect FC symptoms;
  • No clinical significance of colonoscopy examination findings.
  • IBS-C subjects:
  • The diagnostic criteria for constipation-predominant irritable bowel syndrome based on Rome IV criteria;
  • Aged 18 to 65 years;
  • Signed an informed Consent Form (ICF);
  • Complete spontaneous bowel movement (CSBM) <= 2 times/week (CSBM is defined by feeling of complete passage of stool and without the use of laxatives or enemas within 24 hours);
  • Abdominal pain intensity: weekly average of worst daily (in past 24 hours) abdominal pain score of >= 3.0 on a 0 to 10 point scale;
  • Irritable bowel syndrome-symptom severity score (IBS-SSS) >= 175.34;
  • Meet protocol-defined e-Diary completion compliance and agree to refrain from making any new, major life-style changes that may affect IBS-C symptoms;
  • No clinical significance of colonoscopy examination findings.

排除标准

  • Both IBS-C and FC subjects:
  • Drug-induced or secondary causes of constipation;
  • Recent history of mushy or watery stools within one month;
  • Known diagnosis of inflammatory bowel disease, celiac disease, microscopic colitis or other gut inflammatory condition;
  • Must use drugs that may adversely affect the study result during the study period (including but not limited to antibiotic, steroid, analgesic drug, neuromodulator, prebiotic, symbiotic, or probiotic drugs);
  • Severe depression and/or anxiety level (Zung Self-rating Depression Scale (SDS)>= 70 and/or Zung Self-rating Anxiety Scale (SAS) >= 60, and/or Hamilton depression rating scale (HAM-D) >= 19 and/or Hamilton anxiety rating scale (HAM-A) >= 25);
  • Clinical significance of laboratory or imaging tests findings;
  • Allergy to Chinese herbal medicine;
  • Prior medical history of abdominal surgeries within one year;
  • Pregnancy or plans to pregnant or breast-feeding with the study time frame;
  • Frequent alcohol consumption (>= 3 times per week and/or >= 2 drinks categories per session and/or >=3 drinks categories per weekly) consumption;
