SH-DS01 on Fecal Metagenomic Stability

This is a randomized, double blind, Phase 1 study. There will be a 12-week comparison of the safety of DS-01 versus placebo with a secondary outcome measure of the efficacy in a cohort of 100 men or women with IBS with constipation. 50 IBS-C or IBS-M patients will receive DS-01 (Daily Synbiotic, once daily) for 12 weeks, while 50 IBS-C or IBS-M patients will receive the placebo (once daily). Safety is a paramount concern in the study design and will be monitored carefully throughout the study. Study subjects will also receive extensive education on use of the synbiotic.

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder that generates a significant health care burden and is the most commonly diagnosed gastrointestinal condition. Nearly 12% of all patients in the United States seek medical care in primary care practice for IBS and it accounts for 3.1 million ambulatory care visits and 5.9 million prescriptions annually.

The pathophysiology of IBS is distinctly broad compared to other gastrointestinal conditions and includes abnormalities involving motility, visceral sensation, brain-gut interaction, and distress. Though patients with IBS often have a heterogeneous symptom profile, the predominant theme is the presence of abdominal pain or discomfort that is usually relieved by defecation. Host factors such as genetics, immune function, and psychological status, as well as environmental factors such as stress, recent infection, or treatment with antibiotics, could predispose to the development of chronic IBS symptoms. Due to a myriad of contributing factors, a single cause of IBS remains enigmatic. Despite the urgent need to develop better therapies, the high range of placebo response has made clinical trials challenging, ranging from 16.0 to 71.4% with a population-weighted average of 40.2%.

Recent studies have also shown alterations in gut immune response, and a disrupted intestinal and colonic microbiome in association with IBS. The current working hypothesis is that abnormal microbiota activate mucosal innate immune responses, which increase epithelial permeability, activate nociceptive sensory pathways, and dysregulate the enteric nervous system. Targeting the microbiota and gastrointestinal tract with live organisms is a promising approach, yet previous trials have yielded limited success due to empiric strain selection, small population size, and inadequate trial design to control for a high placebo response.

This protocol aims to assess the impact of a multi-strain consortia of 24 commensal organisms across 12 species with extensive strain-specific in vivo data, assessing a range of gastrointestinal symptoms without negatively altering the naive gut microbiota. High-throughput shotgun DNA sequencing will provide opportunity for '-omics'-based analyses of the gut microbiota, which can be augmented by the metabolite profiles resulting from total microbial activity in the gut. Since many of these metabolites are bioeffector molecules acting upon the host, such analysis can provide a direct measure of the consequences of microbial activity in the gut and provide a novel integrated data set for patients with IBS. Recruited subjects will also use a smart-phone application to report day to day gastrointestinal symptoms, a patient-centric hallmark of this chronic gut condition.

Probiotics are live microorganisms with a vast array of therapeutic potential for gastrointestinal disease. Several probiotics strains have shown beneficial outcomes in constipation-predominant IBS (IBS-C) patients, especially as an adjunct to conventional treatment. However, a number of controversial issues regarding the roles of probiotics in pathogenesis of IBS-C remain to be clarified, including precise mechanism of action.

This protocol aims to assess the impact of a mix of 24-beneficial strains on individual gastrointestinal symptoms specifically in a cohort of subjects with IBS-C or IBS-M.

* Patient must be a premenopausal female or male aged 18 and older.
* Patient must have a documented history of IBS that is not completely controlled by current IBS drugs.
* Patient must have a score of ≥150 on the IBS-SSS at screening.
* Patient must have no clinically relevant (in the judgment of the PI) abnormal blood laboratory levels at screening or randomization.
* The clinician will assess eligibility as per the Rome IV criteria (Recurrent abdominal pain or discomfort at least 1 day/week in the last 3 months associated with two or more of the following: Improvement with defecation. Onset associated with a change in frequency of stool).

Exclusion Critieria:

* Patient has clinically significant unstable medical conditions other than IBS.
* Patient has had clinically relevant symptoms or a clinically significant illness in the four weeks prior to screening or randomization.
* Patient has clinically significant laboratory values (in the PI's opinion).
* Patient is currently using or has in the past used recreational or medicinal cannabis, or synthetic cannabinoid based medications (including Sativex®) or supplements (including hemp oil/extracts) within one month prior to study entry and is unwilling to abstain for the duration for the study.
* Patient has consumed any probiotic product three days prior to screening and/or is unwilling to abstain from consuming these during the study.
* Intake of antibiotics in the past 1-month (i.e. penicillin, amoxicillin, cephalexin (Keflex), erythromycin (E-Mycin), clarithromycin (Biaxin), azithromycin (Zithromax), ciprofloxacin (Cipro), levofloxacin (Levaquin), ofloxacin (Floxin), co-trimoxazole (Bactrim), trimethoprim (Proloprim), tetracycline (Sumycin or Panmycin), doxycycline (Vibramycin), gentamicin (Garamycin), or tobramycin (Tobrex).

* Patients who are pregnant, lactating, or planning pregnancy during the course of the study and for three months thereafter.
* Patients who have been part of a clinical trial involving any investigational product in the previous six months.
* Any other significant disease or disorder which, in the opinion of the PI, may either put the patient at risk because of participation in the study, may influence the result of the study, or affect the patient's ability to participate in the study.
* Patient has significantly impaired hepatic function at Visit 1 (Alanine aminotransferase (ALT) \>5 × upper limit of normal (ULN) or bilirubin \>2 × ULN) OR the ALT or Aspartate aminotransferase (AST) \>3 × ULN and the bilirubin \>2 × ULN (or international normalized ratio \>1.5).
