- aging related conditions of chronic inflammation each of which have been shown to have an underlying microbially-mediated inflammatory component.
- Chronic intestinal inflammation can be induced by multiple exogenous and endogenous signals and mediated by multiple immune and nonimmune cells.
- exogenous substances including dietary antigens, pathogenic microorganisms, xenobiotics including antibiotics, or a combination of them, can trigger an initial response mediated primarily by immune cells that initiates mucosal inflammation of the gastrointestinal tract.
- This primary inflammatory response induces a variety of processes, which trigger a secondary inflammatory response, eventually resulting in a self-sustaining cycle of chronic inflammation of the gastrointestinal tract with increased mucosal permeability, tissue damage, cell death and leaky gut symptoms, as well as dysbiosis of the gut microbiome.
- the dysbiotic gut microbiome creates an ideal environment for the establishment of (opportunistic) pathogens, which in turn will also contribute to the severity of the inflammation and its clinical symptoms.
- An example of such condition is IBD, which encompasses two main clinical disorders: Crohn’s disease and Ulcerative Colitis.
- Drug treatments for IBD primarily focus on inflammation control through anti-inflammatory and immunosuppressive therapies.
- Examples of some of the most successful biological drugs for treatment of IBD include corticosteroids for early stages of disease onset, and a range of drugs for treating advanced stages of the disease such as REMICADE (Infliximab; manufactured and sold by Johnson & Johnson subsidiary Janssen Biotech), HUMIRA (Adalimumab; manufactured and sold by AbbVie), Stelara (ustekinumab; manufactured and sold by Johnson & Johnson subsidiary Janssen Biotech), and ENTYVIO (vedolizumab; developed by Millennium Pharmaceuticals, Inc. and sold by Takeda), which target the body’s immune response through key pathways by neutralizing a single cytokine or molecule and induce immunosuppression to control the inflammatory process.

- HUMIRA Adalimumab; manufactured and sold by AbbVie
- Stelara ustekinumab; manufactured and sold by Johnson & Johnson subsidiary Janssen Biotech
- broad-spectrum antibiotics can be detrimental to a healthy gut microbiome by non-selectively eliminating bacterial populations, including protective species that prevent overgrowth of opportunistic pathogens such as Clostridium difficile.
- broad spectrum antibiotics may further contribute to the dysbiotic status of the gut microbiome in IBD patients, with additional negative consequences on the regulation of the innate immune response and the conditions of chronic inflammation.
- microbiome inspired therapeutics are being developed for the treatment of IBD and other conditions linked to chronic inflammation of the gastrointestinal tract. The focus of this work has been on the use of strains belonging to the Clostridium clusters IV and XIVa.
- Clostridium cluster IV and XIVa were found to be successful in decreasing inflammation and necrosis in rodent IBD models (Sokol et al, 2008; Eeckhaut et al, 2009). Van Immerseel et al (2010) suggested the use of Clostridial cluster IV and XIVa strains as preventive and therapeutic probiotics for IBD.
- GF germ-free mice inoculated with healthy human fecal material pretreated with chloroform to enrich for spore-forming bacteria
- Nissan et al developed a 17-strain consortium for IBD treatment (see, e.g., PCT application no.
- This consortium of bacterial strains comprised of Clostridium cluster IV, XIVa and XVIII strains, induced the recruitment / accumulation of regulatory T cells (Treg cells) in the colon.
- Treg cells suppressed proliferation of effector T cells, which in turn lowered the inflammation response by the immune system in the gut (Atarashi et al, 2013).
- these approaches have several disadvantages. First, with enrichment-based approaches, the outcome is defined by the stool sample used in the enrichment, with different samples resulting in different consortia.

- the GUT-108 consortium significantly reduced inflammation in a clinically relevant mouse model of chronic immune-mediated colitis.
- EXAMPLE 2 herein describes evaluation of the efficacy of the GUT-108 consortium to treat an animal model of IBD characterized by chronic T-cell mediated inflammation.
- the preclinical study uses a validated animal model based on ex- germ-free (sterile) Il10 -/- 129SvEv mice where colitis is induced by inoculating the animals with human donor stool which results after 2 weeks in a moderate to severe chronic, bacterial antigen-specific Th1/Th17 driven inflammatory immune response. Mice were treated with GUT-108 consortium 2 weeks after administration of the human donor stool in a therapeutic protocol (i.e., delayed therapy after onset of disease).
- EXAMPLE 2 describes using a validated animal model based on eGFP-reporter (Il10 +/eGFP ) C57BL/6J mice (also referred to as VertX reporter mice). In these mice, which have a wild-type IL-10 phenotype, induction of IL-10 synthesis can be visualized by expression of the eGFP reporter. GUT-108 can be successfully established in gnotobiotic mice models.
- GUT-108 gavaged into two different germ-free mice models, Il-10 +/eGFP VertX reporter and Il10 -/- mice, established engraftment of all strains, as illustrated in Figures 1A and 1B.
- the therapeutic effect of GUT-108 is shown by visual evaluation of the degree of tissue inflammation in representative tissue samples taken from the cecum of the Il10 -/- knock-out mice.
- Figures 2A and 2B are representative histology images of cecum tissue from an ex- germ- free Il10 -/- mouse model of IBD treated with PBS as a control and with GUT 108, respectively, and show that treatment with GUT-108 did not induce colitis in the susceptible germ-free Il10 -/- mice.
- Figures 9A and 9B are representative distal colonic photomicrographs of H&E-stained tissue in an ex- germ- free Il10 -/- mouse model of IBD, where Figure 9A is from a mouse that received PBS as a placebo two weeks after inoculation with human stool to induce colitis and Figure 9B is from a mouse treated with GUT-108 two weeks after inoculation with human stool to induce colitis.
- the figures show the effectiveness of GUT- 108 in reducing the induced inflammation in the cecum tissue relative to the PBS control.
- GUT-108 colonization of gnotobiotic Il10 -/- knock-out mice promoted a healthy gut microbiome with key functionalities for short chain fatty acid (SCFA) synthesis, especially synthesis of acetate and propionate, and IAA synthesis being restored, as shown in Figures 3A-3D.
- SCFA short chain fatty acid
- mice treated with GUT-108 had increased levels of CD4+ GFP+(IL-10+) T cells and Treg cells (Fig.4), especially FOXP3+ ROR ⁇ t+ GFP+(IL-10+) CD4+ Treg cells (Figs.5A-5H).
- the increase in IL-10+ producing CD4+ Treg cells is consistent with a low level of inflammation when germ free mice are exposed to microorganisms.
- elevated levels were observed of IL-10 synthesizing B cells, Dendritic Cells (DC), and Macrophages (Figs.4 and 5A-5H).
- GUT-108 beginning 2 weeks after human fecal colonization to induce colitis resulted in engraftment of all GUT-108 strains except Clostridium scindens GGCC_0168 in the gut microbiome of the Il10 -/- mice.
- therapeutic application of GUT-108 increased the abundance of beneficial resident Clostridium strains (Clusters IV and XIVa) that are not part of the GUT 108 consortium and decreased by 90% the abundance of pathogenic Enterobacteriaceae from 5% to below 0.5% (Fig.6).
- a method includes administering a composition of the present disclosure to a subject to restore a healthier gut microbiome, wherein a healthier gut microbiome can include one or both an increase in the abundance of beneficial Clostridium strains, especially Lachnospiraceae including Dorea species and Lachnoclostridium species that are not GUT-108 constituents, and a decrease in the abundance of pathogenic strains including enterohemorrhagic, enteroaggregative, enterotoxigenic and adherent invasive Escherichia coli, Klebsiella, Salmonella, and Shigella species and pathogenic Clostridium species such as, for example, Clostridium perfringens and Clostridium difficile.
- Progression of inflammation based on levels of lipocalin 2 secreted in the stool of the Il10 -/- knock-out mice as a function of time after gavage with human fecal material (Hu + PBS) and human fecal material plus the GUT-108 consortium in the therapeutic protocol (Hu + GUT-108) is illustrated in Figure 7.
- the significant reduction after three and four weeks of the average lipocalin 2 levels in the stool of the Il10 -/- knock-out mice treated with GUT-108 indicates a decrease in colonic inflammation as compared to the control, showing the therapeutic effect of the GUT-108 consortium to treat chronic colitis.
- a method includes administering a composition of the present disclosure to a subject to restore a healthier gut microbiome, wherein a healthier gut microbiome can result in a reduction in lipocalin 2 levels (or the human equivalent calprotectin where in clinical trials a decrease in calprotectin is considered an indication of a reduction in inflammation of the colonic tissue) and in a reduced stool consistency score.
- the degree of colitis is shown by blinded histological scoring of sections of colon and cecum from the IL-10 -/- mice colonized with human fecal microbiota in Figure 10.
- the results show a statistically significant decrease in blinded histology score for the mice treated with GUT-108, as compared to the mice that did not receive GUT-108.
- This further confirms that the application of GUT- 108 two weeks after the initial gavage with human stool resulted in a reversal of established inflammation, showing the therapeutic effect of GUT-108 on colitis.
- levels of various metabolites were analyzed in the stool samples of the Il10 -/- knock-out mice colonized with human fecal microbiota.
- FIGS. 11A-11B, 12A-12C, and 13A-13B show that compared to treatment with PBS, therapeutic treatment with GUT-108 (four applications over a two-week period after the onset of colitis induced by gavage with the human fecal material) resulted in the increase of levels of various secondary metabolites with beneficial anti-inflammatory properties. Specifically, levels of propionate, indole and its derivatives indole propionate (IPA) and indole acetate (IAA), and secondary bile acids deoxycholic acid (DCA) and lithocholic acid (LCA) were increased. Propionate is a primary nutrient source for colonic epithelial cells, as well as important for T cell induction.
- IPA indole propionate
- IAA indole acetate
- DCA secondary bile acids deoxycholic acid
- LCDA lithocholic acid
- Increased levels of secondary metabolites in stool samples can be used as non-invasive biomarkers to monitor the progression of inflammation and to validate intervention strategies.
- these secondary metabolites have general applicability to monitor the long-term remission of patients treated with common therapeutics for conditions involving chronic inflammation, including corticosteroids and the therapeutics mentioned in Table 3.
- Figures 14A and 14B show a decrease in IL-12p40 and IFN ⁇ synthesis in colon tissue from gut cell cultures of the Il10 -/- knock- out mice colonized with human fecal microbiota and after treatment with GUT-108 further confirming the therapeutic effect of the GUT-108 consortium to treat chronic, immune-modulated colitis.
- FIGS. 15A-15F confirm the therapeutic effect of GUT-108 as shown by significant decrease in levels of expression of biosynthesis genes after treatment with GUT-108 for pro-inflammatory cytokines IL-1b, IL-12b, IL-13, IL-17 ⁇ , IFN ⁇ , and TNF ⁇ in the gut tissue of Il10 -/- knock- out mice colonized with human fecal microbiota; and after treatment with GUT-108 a significant increase in levels of expression of biosynthesis genes for homeostatic cytokine IL-15 in the gut tissue of Il10 -/- knock-out mice colonized with human fecal microbiota .
- a method includes administering a composition of the present disclosure to a subject to restore a healthier gut microbiome, wherein a healthier gut microbiome can be characterized by a decrease in the synthesis of proinflammatory cytokines.
- a decrease in the synthesis of proinflammatory cytokines after treatment with GUT-108, increased colonic expression levels of genes for receptors and pathways implicated in mucosal healing was observed by Q-PCR in the gut tissue of Il10 -/- knock-out mice colonized with human fecal microbiota as shown in Figures 16A-16G.
- a method includes administering a composition of the present disclosure to a subject to restore a healthier gut microbiome, wherein a healthier gut microbiome can be characterized by a decrease in IFN- ⁇ +, IL-17 ⁇ + and IFN- ⁇ + IL-17 ⁇ + synthesizing CD4+ T cells.
- a method includes administering a composition of the present disclosure to a subject to restore a healthier gut microbiome, wherein a healthier gut microbiome can be characterized by a decrease in FOXP3+ CD4+ T cells indicative for reduced levels of epithelial inflammation.
- the increased levels of various IL-10 synthesizing immune cell types points to a systemic anti- inflammatory response induced by GUT-108 that has broad applicability for treatment of a range of conditions characterized by a disease pathology including chronic inflammation of the gastrointestinal tract, such as Inflammatory Bowel Diseases (IBD), Irritable Bowel Syndrome (IBS), graft versus host disease, Parkinson’s disease, ALS, systemic lupus erythematosus, asthma, multiple sclerosis, food allergies, fatty liver, hepatic encephalopathy, type-2 diabetes, metabolic syndrome and obesity, psoriasis, and well as aging related conditions caused by chronic inflammation, each of which have been shown to have a microbially-mediated inflammatory component.

- the current standard of care drugs are targeting the downstream effects on immune pathways neutralizing a single cytokine or molecule, such as the elevated levels of the pro-inflammatory cytokines TNF ⁇ , IL-12 and IL-23, and IL-17.
- successful long-term remission by these drugs requires that dysbiosis of the gut microbiome, which is characteristic for these diseases, is corrected.
- GUT-108 can be used both preventatively and therapeutically for the treatment of ulcerative colitis, Crohn’s disease, Ankylosing Spondylitis, Plaque Psoriasis, Psoriatic Arthritis and Pouchitis as a stand-alone therapeutic, lowering the expression of multiple pro-inflammatory cytokines; or as a companion therapy to corticosteroids and the drugs listed in Table 3 to reduce the treatment time to achieve remission, and to ensure long-term remission by correcting the underlying causes of the disease.
- a method includes administering a composition of the present disclosure to a subject to decrease inflammation, either as a stand-alone treatment or as an adjuvant therapy.
- the inflammation can be a result of one or more disorders including Inflammatory Bowel Diseases (IBD) like ulcerative colitis and Crohn’s disease, Pouchitis, Irritable Bowel Syndrome (IBS), graft versus host disease, Parkinson’s disease, ALS, multiple sclerosis, systemic lupus erythematosus, Ankylosing Spondylitis, asthma, food allergies, fatty liver, hepatic encephalopathy, Primary Sclerosing Cholangitis as a comorbidity for IBD, type-2 diabetes, metabolic syndrome and obesity, Plaque Psoriasis, Psoriatic Arthritis, and aging related conditions of chronic inflammation.

- the aldehyde dehydrogenases Aldh1A1 and Aldh1A2 were identified as one of the functions whose gene expression levels can be significantly upregulated by the therapeutic application of GUT- 108. Upregulation of Aldh1A1 and Aldh1A2 has been associated with increased activity of the retinoic acid pathway, which is critical in regulating Wnt/ ⁇ -catenin signaling.
- GUT-108 may exert beneficial effects through a combination of multiple modes of action to treat the upstream causes of inflammation by correcting dysbiosis, activating various IL10 synthesizing immune cells, lowering inflammatory responses, and restoring normal bacterial metabolic profiles.
- These overlapping protective mechanisms may result in maintenance of long-term remission of IBD and other diseases characterized by a pro-inflammatory gut microbiome in a physiologic and safe manner.

- computational models were first built for the individual GUT-108 strains (Henry et al, 2010). All strain models required some degree of gap filling to ensure that they are capable of synthesizing or acquiring all the small molecule building blocks required to produce new biomass. This gap filling was performed in silico mimicking a specific growth condition; it is preferable to perform gap filling mimicking minimal medium composition. The initial in silico gap filling was therefore performed in glucose minimal medium.

- the average lipocalin 2 levels in the stool of Il10 -/- knock-out mice treated with human fecal material were 723 ng/g and 3675 ng/g, respectively, this in contrast to the lipocalin 2 levels in the stool of Il10 -/- knock-out mice that two weeks after the initial gavage with human fecal material had received GUT-108, which were 91 ng/g and 531 ng/g (after 2 and 3 weeks, respectively; see Fig.7).
- FIG. 9A and 9B show the effectiveness of GUT-108 in reducing the induced inflammation in the cecum tissue relative to the PBS control.
- the images in Figures 2A and 2B show that compared to PBS, four applications over a two-week period of GUT-108 via gavage to germ-free Il10 -/- mice did not result in the onset of inflammation in the cecum.
- Fig.9A gavage with human stool resulted in the onset of moderate to severe colitis
- Fig.9B therapeutic treatment with GUT-108 (four applications over a two- week period after the onset of colitis induced by gavage with human fecal material) resulted in a significant decrease in the level of inflammation (Fig.9B).
- the degree of colitis was further examined by histological scoring (Sellon et al, 1998). Mice were killed four weeks after initial gavage with human fecal material. At necropsy, sections of colon (proximal, transverse, and distal) and cecum were fixed in 10% neutral buffered formalin. Duodenal and gastric tissue samples were taken from representative animals.
- increased levels of propionate may positively affect increased mucosal permeability that contributes to the severity of inflammatory disorders including ulcerative colitis, Crohn’s disease, Ankylosing Spondylitis, Plaque Psoriasis, Psoriatic Arthritis and Pouchitis.
- the results show the importance of including non-Clostridium, propionate synthesizing strains in the GUT-108 composition.
- butyrate synthesis can be based on the fermentation of amino acids, such as lysine, a process that contributes to inflammation associated with mucosal permeability.
- butyrate levels can be considered as a less reliable biomarker for monitoring gut microbiome dysbiosis and progression of inflammation linked to a broad spectrum of disease conditions with a gut microbiome component.
- Increased synthesis of indole and its derivatives indole propionate (IPA) and indole acetate (IAA) was observed in mice humanized with a fecal transplant that received therapeutic application of GUT- 108 (Figs.12A-12C).
- IPA is considered a potent AhR pathway agonist that is critical in controlling epithelial barrier integrity.
- the increased synthesis of indole, IPA and IAA as the result of the therapeutic application of GUT-108 can positively contribute to gut epithelial healing, thus positively affecting the severity of inflammatory disorder including ulcerative colitis, Crohn’s disease, Ankylosing Spondylitis, Plaque Psoriasis, Psoriatic Arthritis and Pouchitis.
- the results also show the importance of including non-Clostridium, indole synthesizing strains in the GUT-108 composition.
- IPA and IAA provide a non-invasive biomarker to monitor the progression of inflammation and to validate intervention strategies that aim at addressing the increased mucosal permeability by restoring normal function to a dysbiotic gut microbiome.
- Metabolite analysis confirmed that the complex multi-strain pathway for the conversion of bile salts into therapeutic secondary bile acids did become engrafted and was functional in a humanized mouse model. This is shown for deoxycholic acid (Fig.13A) and lithocholic acid (Fig.13B), both of which have important therapeutic effects on health and infection control.
- Clostridium scindens GGCC_0168 When applied to Il10 -/- mice humanized with a fecal transplant, all GUT-108 strains except Clostridium scindens GGCC_0168 became established (Fig.6). Clostridium scindens has been previously described as one of the essential strains necessary to convert primary bile acids into LCA and DCA. However, despite the absence of this strain, the established functional multi-strain network produced secondary bile acids, with Extibacter sp. GGCC_0201 providing the 7 ⁇ -dehydratase activity required to convert CA and CDCA into the therapeutic secondary bile acids DCA and LCA, respectively.
- Normalizing the intestinal bile acid profile can restore intestinal epithelial stem cell function, and increase colonic ROR ⁇ + Treg cell counts that ameliorate host susceptibility to colitis, while LCA stimulate differentiation to Tregs and inhibit Th17 cells consistent with GUT-108’s ability to restore secondary bile acid metabolism (Figs.13A-13B) and activate inducible IL10+ ROR ⁇ FoxP3+ CD4+ Treg cells (Figs.5E, 5G).
- Lithocholic acid has also been reported to have an anti-aging effect due to its effect on mitochondrial lipid composition and energy processes, while deoxycholic acid is a strong antimicrobial with potent mode of action against microbial infections by pathogenic bacteria, including Clostridium perfringens and Clostridium difficile.
- the evolution of the levels of secondary bile acids, especially deoxycholic acid and lithocholic acid, provides a non-invasive biomarker to monitor and validate intervention strategies that aim at restoring a dysbiotic gut microbiome and to control infections by (opportunistic) pathogenic bacteria that thrive in the dysbiotic gut environment, including Clostridium perfringens and Clostridium difficile.
- the observed eight-fold decrease observed for the levels Clostridium perfringens in the mice treated with GUT-108 (Fig.6) support the importance of increased levels of deoxycholic acid for pathogen control, including pathogenic Clostridium species such as, for example, Clostridium perfringens and Clostridium difficile.
- the levels of secondary metabolites in stool samples can be used as non- invasive biomarkers to monitor the progression of inflammation and to validate intervention strategies, including long-term remission of patients treated with common therapeutics for conditions involving chronic inflammation, including the therapeutics mentioned in Table 3.
- the spontaneous secretion levels of IL-12p40 and IFN ⁇ are very good indicators of the level of immune activation and inflammation of the colonic tissue.

- the results are presented in Figures 15A-15G and confirm the therapeutic effect of GUT-108, as illustrated by the significant decrease in levels of expression of the biosynthesis genes for the pro-inflammatory cytokines IL-1b, IL-12b, IL-17 ⁇ , IFN ⁇ , IL-13, TNF ⁇ ; IL-6 synthesis was also reduced by approximately 60% (results not shown).
- the level of expression of the biosynthesis gene for the homeostatic cytokine IL-15 was found to be significantly increased.
- Ahr pathway genes including the aryl hydrocarbon receptor (Ahr), the aryl hydrocarbon receptor repressor (AhrR) and the Cytochrome P450 Family 1 Subfamily A Member 1 (Cyp1A1) gene (Neavin et al, 2018) were significantly upregulated.
- Wnt/ ⁇ -catenin signaling pathway Several cellular pathways, including Wnt/ ⁇ -catenin signaling pathway, are related to cancer metastasis, and many reports have suggested that exaggerated Wnt signaling can lead to cancer initiation and progression in a wide range of human tissues, including colon cancer, which has higher occurrence in IBD patients compared to healthy individuals. Therefore, increased expression of Aldh1A1 and Aldh1A2 as part of the retinoic acid pathway by GUT-108 has the potential to lower the risk of colorectal cancer in IBD patients.
- AHR acts as a sensor of the microbiota community and, through its established role of a modulating immune functions, maintains host-microbe homeostasis.
- IPA is also a pregnane X receptor (PXR) agonist mediating its responses through TLR4.
- PXR pregnane X receptor
- AHR is a critical mediator of anti-inflammatory responses to infection by bacterial pathogens and of the differentiation and function of immune cells including T cells, innate lymphoid cells, macrophages and DC.
- AHR promotes the expression of the anti- inflammatory cytokine IL-10 and inhibits macrophage apoptosis, decreases the expression of inflammatory cytokines (IL-6 and TNF- ⁇ ) and inhibits activation of NF- ⁇ B. Therefore, the Ahr pathway is critical to protect from excessive inflammatory cytokine expression and septic shock. In addition, Ahr pathway activation protects the mucosa during inflammation.
- Upregulation of Ahr has been associated with a positive outcome of various aging related conditions via its effect on various targets, including P-glycoprotein expression, fibroblast growth factor, tight junction proteins in the blood brain barrier, and the differentiation and function of immune cells, including T cells, macrophages and dendritic cells.
- Ahr activation via the gut microbiome will activate these targets, which has been described to have a positive effect on the development of Alzheimer's and Non-Alzheimer’s disease related dementia, Parkinson’s disease, multiple sclerosis, Type-2 diabetes, obesity, hepatic steatosis, and aging related cardiovascular and neurologic conditions, all of which have an underlying gut microbiome component.
- GUT-108 is provided as a therapeutic agent for the treatment of these conditions.
- the anti-inflammatory effect of GUT-108 was also evaluated by determining the populations of CD4+ T cells in the lamina intestinal of the colon that synthesized the pro-inflammatory cytokines IL-17 ⁇ and IFN ⁇ .
- the results are presented in Figures 17A-17C and show a significant decrease of IFN- ⁇ +, IL- 17 ⁇ + and IFN- ⁇ + IL-17 ⁇ + synthesizing CD4+ T cells in the tissue of the colonic lamina intestinal of mice that had received GUT-108 in a therapeutic protocol after induction of moderate to severe colitis with human fecal material, as compared to mice that received the PBS placebo control.
- Antigen-presenting cell production of IL-10 inhibits T-helper 1 and 17 cell responses and suppresses colitis in mice.
