SH-DS01 on Fecal Metagenomic Stability
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.
This is a randomized, double blind, 12-week comparison of the efficacy and safety of DS-01
 versus placebo 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.
Inclusion Criteria:

 -  Patient must be willing and able to give informed assent/ consent for participation in
 the study

 -  Patient must be willing and able (in the PI's opinion) to comply with all study
 requirements.

 -  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). The supplement in the
 present study may have a minor interaction with these medications.

 -  Patient has any known or suspected hypersensitivity to pomegranate, pine, or
 mushrooms, or any of the excipients of the Supplement Synbiotic Product (SSP).

 -  Patients of child bearing potential unless willing to ensure that they use effective
 contraception, for example, oral contraception, double barrier, intra-uterine device,
 during the study and for three months thereafter.

 -  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).
