[0002] Field of Invention This disclosure relates to methods for reducing enterotoxemia, restoring the microbiome, and / or increasing the recovery of the microbiome (e.g., after an enterotoxemia-induced event) by administering a pharmaceutical composition to a subject. Also provided are methods for protecting and / or establishing the microbiome of a subject by administering a pharmaceutical composition to a subject. [Background technology]

[0003] The human gut microbiome consists of tens of trillions of bacteria from over 1,000 identified species. An individual's microbiome is as unique as a fingerprint, and even among close relatives, there is considerable diversity. The majority of species in the human microbiome are commensal organisms, neither harming nor injuring their host. Many bacterial species residing in the human gut, including members of the taxonomic groups Lactobacillus, Firmicutes, and Bacteriodetes, are symbiotic organisms that perform functions beneficial to humans, such as the metabolism of food by-products into absorbable nutrients. However, pathogenic bacterial species, such as strains of Escherichia coli, can also reside in the human gut and, if excessively concentrated in the human microbiome, can cause disease. Therefore, maintaining a balance of bacterial species within the human microbiome is crucial for overall human health.

[0004] Disruptions in the abundance of bacterial species within the human microbiome, decreased bacterial diversity, and altered bacterial functional capacity are signs of enterotoxosis, which can result from events such as infection, recurrent and inadequate antibiotic treatment, and inflammation. Enterotoxosis occurs when the presence of few commensal or symbiotic bacterial species in the human microbiome leads to a proliferation of opportunistic pathogenic species. Conventional therapies to reverse enterotoxosis and restore the microbiome include fecal transplantation (FMT). While FMT can be effective in treating enterotoxosis, it lacks a standardized method for administration and carries the potential risk of in transplanting pathogens or allowing pathogen proliferation to occur before recovery is achieved.

[Figure 43] This study demonstrates that the VE303 consortium and strain 6 (Dorea longicatena) reduced Clostridium difficile (C. difficile) growth in in vitro competitive experiments. VE303 without Dorea longicatena was less effective in suppressing VE303 growth. C. difficile cultures were cultured in the presence of Clostridium bifermentans (positive control), VE303, Dorea longicatena, VE303 without Dorea longicatena, or in the absence of one or more competing strains (C. difficile only). The amount of C. difficile is presented as a percentage of the control (C. difficile only). [Figure 44] This disclosure presents various charts illustrating different treatment cohorts.

[Figure 60] This document provides a summary of exemplary methods described herein for defining the pharmacokinetics (PK) and pharmacodynamics (PD) of live biological products (LBPs). The genomic sequences and unique marker sequences of each LBP consortium member may be identified, bacterial strains may be used to colonize the target, and the effects of the LBP on the target's symbiotic microbiome may be observed during LBP development. Short-chain fatty acids (SCFAs) and bile acids (BAs) in feces may be useful in characterizing the PD of LBPs designed for the treatment of specific indications. [Figure 61]This model illustrates the relationship between the microbiome and metabolites and VE303 administration. It shows a simplified model of interactions between symbiotic microorganisms, BA, SCFA, and intestinal epithelium in the gut of healthy humans (left panel), under conditions of Clostridium difficile infection (center panel), and in healthy humans after VE303 administration resulting in restoration of microbiome, bile acid, and SCFA homeostasis (right panel).

[0053] Methods for reducing enterotoxosis in subjects receiving a pharmaceutical composition containing one or more purified bacterial strains are provided herein. Methods for restoring the microbiome in subjects receiving a pharmaceutical composition containing one or more purified bacterial strains are provided herein. Methods for increasing the recovery of the microbiome in subjects receiving a pharmaceutical composition containing one or more purified bacterial strains are also provided herein. Methods for protecting the microbiome of subjects receiving a pharmaceutical composition containing one or more purified bacterial strains are also provided herein. Methods for establishing bacteria in the microbiome of subjects receiving a pharmaceutical composition containing one or more purified bacterial strains are also provided herein.

[0054] The present invention is not limited in its application to the structural and arrangement details of the components shown in the following description or illustrated in the drawings. Other embodiments of the present invention are possible and can be practiced or carried out in various ways. Furthermore, the expressions and terms used herein are for illustrative purposes only and should not be considered limiting. The use herein of “including,” “comprising,” “having,” “containing,” “involving,” and variations thereof means to include the items listed below and their equivalents, as well as additional items.

[0055] Aspects of this disclosure relate to a method for reducing enterotoxemia in a subject, comprising administering a therapeutically effective amount of a pharmaceutical composition comprising one or more purified bacterial strains to the subject. In some embodiments, the pharmaceutical composition is administered to reduce enterotoxemia of the subject's intestinal microbiota. In some embodiments, the method further comprises administering one or more additional doses or amounts of the pharmaceutical composition described herein. In some embodiments, the method further comprises administering vancomycin to the subject prior to the administration of the pharmaceutical composition.

[0056] As used herein, “enterotoxemia” refers to an imbalance of the microbiome within or on the surface of an object. The microbiome, for example, in mammalian objects, is present on the skin, in the gastrointestinal tract (i.e., the intestines), in the oral cavity, and in the vaginal canal of female objects, and includes bacteria, archaea, protists, fungi, and viruses. In some cases, species present in the microbiome benefit the object by performing useful or necessary functions, such as assisting in the digestion of food in the object's intestinal tract, protecting the body from the invasion of pathogenic microorganisms, and promoting immune progression. Organisms in the microbiome that perform these functions are sometimes referred to as symbiotic or commensal organisms because they are present in the object without causing harm and, in some cases, actually benefit the host. In enterotoxemia, a variety of diseases and / or disorders can result from the disruption or damage of the object's normal microbiome. Enterotoxemia can result, for example, the loss of beneficial species, loss of microbial diversity, an increase in pathogenic organisms (one or more), and / or changes in metabolic capacity. In some embodiments, species that normally dominate the microbiome become few in number (e.g., commensal or symbiotic species), and species that normally exist in small numbers (e.g., opportunistic species) become dominant. See also Petersen et al., "Defining dysbiosis and its influence on host immunity and disease." Cell Microbiol 2014, July 16(7), 1024-1033. It should be understood that the compositions and methods of this disclosure may reduce enterotoxosis in various ways in some embodiments. For example, in some embodiments, the compositions and methods result in an increase in the abundance of beneficial bacterial species in the microbiome. In some embodiments, the compositions and methods result in a decrease in the abundance of pathogenic bacterial species. However, it should also be understood that the compositions and methods provided herein do not necessarily reduce all characteristics of enterotoxosis. For example, in some embodiments, the compositions and methods result in an increase in the abundance of beneficial bacterial species in the microbiome, but without simultaneously increasing the diversity of the microbiome. This disclosure relates to a method for reducing enterotoxemia in the subject.As used herein, “reduction of enterotoxemia” refers to the restoration of the composition and homeostasis of the microbial community.

[0057] Disruption of the microbiome can allow pathogens from within or from other sources to colonize, overcrowde, and / or cause disease in the subject. Enterotoxosis is associated with many diseases and / or disorders, including Clostridium difficile infection, cancer, inflammatory bowel disease (IBD), obesity, colitis, chronic fatigue syndrome, periodontitis, and bacterial vaginosis.

[0058] Enterotoxemia can be detected and / or monitored by a variety of methods, including stool tests (e.g., identification and / or quantification of microbial populations, enzyme assays, metabolite assays, immune function tests), hydrogen / methane breath tests, and many others.

[0059] In some embodiments, a reduction in enterotoxemia is accompanied by a change (increase or decrease) in the abundance of one or more bacterial populations. Bacterial abundances (e.g., bacteria belonging to a particular phylum), including the abundance of a specific species or strain of bacteria and the abundance of a bacterial population, can be assessed using any method known in the art. Generally, bacterial abundances may be assessed directly or indirectly. Examples of methods for directly assessing bacterial abundance in a sample (e.g., a microbiome or a sample thereof) include identifying and quantifying bacterial strains in a fecal sample from a subject. Examples of methods for indirectly assessing bacterial abundance in a sample (e.g., a microbiome or a sample thereof) include sequencing of nucleic acid samples (e.g., 16S rRNA genes of a given bacterial species or other bacterial genes obtained from a fecal or biopsy sample), and detection and quantification of metabolites associated with specific bacteria in a fecal sample from a subject (e.g., phospholipid fatty acid metabolism, microbial biomass carbon analysis).

[0060] The abundance of one or more bacterial populations in a sample from a subject may be compared to the abundance of bacterial populations in samples from the same subject obtained at a different time (e.g., previously or later). Alternatively, the abundance of one or more bacterial populations in a sample from a subject may be compared to the abundance of bacterial populations in samples from a different subject (e.g., a reference subject).

[0061] In some embodiments, enterotoxosis of the microbiome of interest (e.g., the gastrointestinal microbiome) is characterized by an increased abundance of microorganisms associated with inflammation and / or disease. In some embodiments, enterotoxosis is characterized by an increased abundance of Proteobacteria. In some embodiments, the increased abundance of microorganisms associated with inflammation and / or disease is compared to the abundance of microorganisms associated with inflammation before exposure to an event referred to as an enterotoxosis-induced event, as described herein.

[0062] In some embodiments, enterotoxosis of the target microbiome (e.g., gastrointestinal microbiome) is characterized by a decrease in the abundance of microorganisms that are thought to provide one or more beneficial effects to the target. In some embodiments, enterotoxosis of the target microbiome (e.g., gastrointestinal microbiome) is characterized by a decrease in the abundance of bacteria of the phylum Bacteroidetes. In some embodiments, enterotoxosis of the target microbiome (e.g., gastrointestinal microbiome) is characterized by a decrease in the abundance of bacteria of the phylum Firmicutes. In some embodiments, enterotoxosis of the target microbiome (e.g., gastrointestinal microbiome) is characterized by a decrease in the abundance of bacteria belonging to Clostridium cluster IV and / or XIVa. In some embodiments, enterotoxosis of the target microbiome (e.g., gastrointestinal microbiome) is characterized by a decrease in the abundance of bacteria belonging to Clostridium cluster XVII. In some embodiments, the decrease in the abundance of beneficial microorganisms is compared to the abundance of microorganisms associated with inflammation prior to exposure to an event referred to as an enterotoxosis-inducing event, as described herein.

[0063] In some embodiments, the reduction in enterotoxemia leads to an increase in the abundance of bacteria of the phylum Bacteroidetes (e.g., bacteria of the genus Bacteroides) compared to the abundance of Bacteroides in the subject (or its microbiome) before administration of the pharmaceutical composition. In some embodiments, the reduction in enterotoxemia leads to an increase in the abundance of bacteria of the phylum Bacteroidetes (e.g., bacteria of the genus Bacteroides) compared to the abundance of Bacteroides in the subject (e.g., reference subject) (or its microbiome) that did not receive the pharmaceutical composition. In some embodiments, the reduction in enterotoxemia leads to an increase in the abundance of one or more bacterial species belonging to the genus Bacteroides. In some embodiments, the reduction in enterotoxemia leads to an increase in the overall abundance of bacterial species belonging to the genus Bacteroides.

[0064] In some embodiments, the methods described herein increase the abundance of Bacteroides.

[0089] In some embodiments, according to the methods provided herein, administration of the pharmaceutical compositions described herein increases the abundance of bacterial species of the phylum Bacteroidetes and decreases the abundance of bacterial species of the phylum Proteobacteria.

[0090] In some embodiments, the reduction in enterotoxemia does not correlate with a proportional increase in the diversity of the target microbiome. While microbiome diversity is generally associated with a healthy microbiome, it has been unexpectedly found herein that the compositions and methods provided herein can restore the strength of the microbiome without restoring diversity. Although not limited to a specific mechanism, it is believed that the microbiome is restored by the composition of the pharmaceutical compositions provided herein. For example, a limited number of Clostridium cluster XIVa bacterial strains in a composition can take the role of a larger group of Clostridium cluster XIVa strains found in an untreated healthy microbiome. Thus, a microbiome treated with the compositions provided herein and according to the methods provided herein may exhibit all the characteristics of a healthy microbiome, but may not have the high diversity that is sometimes associated with a healthy microbiome.

[0091] Aspects of this disclosure relate to a method for restoring a target microbiome, comprising administering a therapeutically effective amount of a pharmaceutical composition containing one or more purified bacterial strains. In some embodiments, the method further comprises administering one or more additional doses of the pharmaceutical composition described herein. In some embodiments, the method further comprises administering an antibiotic to the target prior to the administration of the pharmaceutical composition. In some embodiments, the method further comprises administering vancomycin to the target prior to the administration of the pharmaceutical composition.

[0092] As used herein, “microbiome restoration” refers to the re-establishment or recovery of the relative abundance and / or microbial diversity of the bacterial population of the subject’s gastrointestinal microbiome. In some embodiments, the subject’s microbiome is restored to a healthy subject microbiome (healthy microbiome). In some embodiments, the subject’s microbiome is restored to a previous microbiome of the same subject. In some embodiments, the subject whose microbiome is being restored may have an inflammatory condition such as irritable bowel syndrome, ulcerative colitis, or Crohn’s disease. In some embodiments, the subject whose microbiome is being restored may have allergies (e.g., food allergies). In some embodiments, the subject’s microbiome is restored to the same subject’s microbiome prior to the inflammatory condition. Therefore, it should be understood that the microbiome requiring restoration may not have experienced an enterotoxosis-inducing event. Following the methods provided herein, in some embodiments, the subject requiring microbiome restoration may not have experienced an enterotoxosis-inducing event. In some embodiments, the subject requiring microbiome restoration does not have a Clostridium difficile infection. In some embodiments, the subject requiring microbiome restoration has not been treated with antibiotics.

[0093] Microbiota requiring restoration are characterized, for example, by the presence of identifying features associated with damaged microbiota. Generally, microbiota can be characterized based on the presence or absence of bacteria or populations of specific bacterial species. For example, damaged microbiota may be overcrowded with pathogens and / or have a reduced presence of commensal bacteria. Damaged microbiota can also be characterized by their biological function. For example, damaged microbiota may be unable to maintain the mucosal barrier and healthy immune function, and / or may be unable to fight infection and healthy microbiota.

[0094] In some embodiments, restoring the target microbiome results in a microbiome substantially similar to a healthy microbiome (e.g., a healthy target microbiome). In some embodiments, restoring the target microbiome results in a microbiome that is more similar to a healthy microbiome than to a damaged microbiome. In some embodiments, restoring the target microbiome results in the restoration or increase of the presence of one or more populations of bacteria or a particular bacterial species. In some embodiments, restoring the target microbiome results in the recovery or decrease of the presence of one or more populations of bacteria or a particular bacterial species. In some embodiments, restoring the target microbiome results in the improvement of one or more functions of the microbiome. In some embodiments, restoring the target microbiome results in the deterioration of one or more functions of the microbiome.

[0095] In some embodiments, the pharmaceutical compositions described herein can restore the microbiome without restoring its complete diversity. While microbiome diversity is generally associated with a healthy microbiome, it has been unexpectedly found herein that the compositions and methods provided herein can restore the intensity of the microbiome without restoring diversity (e.g., as defined by the Shannon index). Without wishing to limit ourselves to any particular theory, the microbiome is restored by the composition of specific bacterial strains administered in the composition and by the treatment methods and drug regimens provided herein. For example, a limited number of bacterial strains belonging to the Clostridium cluster XIVa in the composition may play the role of a larger group of XIVa strains found in an untreated healthy microbiome. Thus, a microbiome treated with the compositions described herein may exhibit the distinctive characteristics of a healthy microbiome (including the presence of Bacteroidetes and Firmicutes and the absence of Proteobacteria), but may not possess the high diversity typically associated with a healthy microbiome.

[0096] As used herein, “healthy microbiome” refers to the microbiome from an object without overt disease (e.g., a healthy object). While the microbial composition of a healthy microbiome can vary considerably, several tendencies characterizing a healthy microbiome have been identified. For example, the gastrointestinal microbiome may perform a number of metabolic and / or other molecular functions, including the metabolism of carbohydrates, lipids, and other nutrients, which are carried out by a healthy microbiome, regardless of the composition of specific species. In some cases, the metabolic and molecular functions performed by a healthy microbiome are not those that the host object can perform, resulting in a symbiotic host-microbe relationship. In addition, a healthy microbiome tends to be resilient to external (e.g., diet or medication) and / or internal (e.g., age, disease state, stress, inflammation) changes in the object. The resilience of a healthy microbiome can also be characterized by its ability and speed to restore a healthy state after a disturbance. Alternatively, or in addition, a healthy microbiome may be characterized by a higher relative abundance (e.g., over 75%) of bacterial species from the phylum Firmicutes and the genus Bacteroides compared to species from the phylum Proteobacteria.

[0097] In some embodiments, subjects with restored or healthy microbiomes exhibit increased abundance of bacteria from the phylum Firmicutes and / or genus Bacteroides compared to bacteria from the phylum Proteobacteria.

[0098] In some embodiments, subjects with restored or healthy microbiomes exhibit increased abundance of bacteria from the Firmicutes and / or Bacteroidetes phyla compared to bacteria from the Proteobacteria phylum.

[0099] In some embodiments, the subjects have not received or experienced an enterotoxosis-inducing event. In some embodiments, the subjects have not received or experienced an enterotoxosis-inducing event one week, two weeks, three weeks, four weeks, five weeks, six weeks, seven weeks, eight weeks, nine weeks, ten weeks, twelve months, six months, seven months, eight months, nine months, ten months, eleven months, twelve months, or more prior to administration of the pharmaceutical composition described herein. In some embodiments, the subjects do not have an infection. In some embodiments, the subjects have not had an infection one week, two weeks, three weeks, four weeks, five weeks, six weeks, seven weeks, eight weeks, nine weeks, ten weeks, twelve months, six months, seven months, eight months, nine months, ten months, eleven months, twelve months, or more prior to administration of the pharmaceutical composition described herein. In some embodiments, the subjects do not have a Clostridium difficile infection. In some embodiments, the subject has not had a Clostridium difficile infection one week, two weeks, three weeks, four weeks, five weeks, six weeks, seven weeks, eight weeks, nine weeks, ten weeks, twelve months, six months, seven months, eight months, nine months, ten months, eleven months, twelve months, or more prior to administration of the pharmaceutical composition described herein. In some embodiments, the subject has not been treated with antibiotics. In some embodiments, the subject has not been treated with antibiotics one week, two weeks, three weeks, four weeks, five weeks, six weeks, seven weeks, eight weeks, nine weeks, ten weeks, twelve weeks, six months, seven months, eight months, nine months, ten months, eleven months, twelve months, or more prior to administration of the pharmaceutical composition described herein. In some embodiments, the subject has not been treated with vancomycin. In some embodiments, the subject has not been treated with vancomycin one week, two weeks, three weeks, four weeks, five weeks, six weeks, seven weeks, eight weeks, nine weeks, ten weeks, twelve weeks, six months, seven months, eight months, nine months, ten months, eleven months, twelve months, or more prior to administration of the pharmaceutical composition described herein.

[0100] Aspects of this disclosure relate to methods for increasing the recovery of a healthy microbiome in a subject after an enterotoxemia-induced event, the methods comprising administering a therapeutically effective amount of a pharmaceutical composition containing one or more purified bacterial strains. In some embodiments, the methods further comprise administering one or more additional doses of the pharmaceutical composition described herein. In some embodiments, the methods further comprise administering an antibiotic to the subject prior to administering the pharmaceutical composition. In some embodiments, the methods further comprise administering vancomycin to the subject prior to administering the pharmaceutical composition.

[0101] As used herein, the term “increasing the recovery” of a healthy microbiome refers to an increase in the rate of recovery or the overall degree of recovery (e.g., the microbiome of the subject is more similar to a healthy microbiome after administration of the pharmaceutical composition). In some embodiments, increasing the recovery of a healthy microbiome refers to an increase in the rate of recovery. In some embodiments, recovery of a healthy microbiome refers to an increase in the overall degree of recovery (e.g., the microbiome of the subject is more similar to a healthy microbiome after administration of the pharmaceutical composition). In some embodiments, “increasing the recovery” of a healthy microbiome refers to an increase in both the rate of recovery and the overall degree of recovery. In some embodiments, after administration of any of the pharmaceutical compositions described herein, a healthy microbiome is recovered more rapidly in the subject compared to the recovery of a healthy microbiome in a subject that did not receive the pharmaceutical composition. In some embodiments, after administration of any of the pharmaceutical compositions described herein, a healthy microbiome is recovered more rapidly in the subject compared to the recovery of a healthy microbiome in a subject that received a fecal matter transplant. In some embodiments, the increased recovery of a healthy microbiome occurs at least 1, 2, 3, 4, 5, 6 days, 1, 2, 3, 4, 5, or 6 weeks earlier than the recovery of a healthy microbiome in subjects that were not administered the pharmaceutical composition. In some embodiments, the increased recovery of a healthy microbiome occurs at least 1, 2, 3, 4, 5, 6 days, 1, 2, 3, 4, 5, or 6 weeks earlier than the recovery of a healthy microbiome in subjects that did not receive fecal matter transplantation.

[0102] In some embodiments, increasing the recovery of a healthy microbiome refers to an increase in the recovery rate. In some embodiments, the recovery of a healthy microbiome occurs within 1, 2, 3, 4, 5, 6 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, or 6 weeks from the administration of the pharmaceutical composition described herein. In some embodiments, the recovery of a healthy microbiome occurs 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, 20 times, 100 times faster, or more, compared to subjects not treated with the pharmaceutical composition according to the methods provided herein.

[0103] In some embodiments, increasing the recovery of a healthy microbiome refers to an increase in the overall degree of recovery. In some embodiments, the recovery of a healthy microbiome is 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, 125%, 150%, or better compared to subjects not treated with the pharmaceutical composition according to the methods provided herein.

[0104] In some embodiments, recovery occurs without the detection of colonization of one or more bacterial strains of the pharmaceutical composition. In some embodiments, recovery of a healthy microbiome is associated with colonization of one or more bacterial strains of the pharmaceutical composition.

[0105] In some embodiments of the methods provided herein, the subject is experiencing an enterotoxosis-inducing event. In some embodiments of the methods provided herein, the subject is experiencing an enterotoxosis-inducing event prior to administration of a single or multiple dose of the pharmaceutical composition provided herein. As used herein, the term “enterotoxosis-inducing event” refers to one or more events that disrupt the microbiome of the subject. In some embodiments, the subject who has experienced an enterotoxosis-inducing event requires administration of one of the pharmaceutical compositions described herein. In some embodiments, the subject who has experienced an enterotoxosis-inducing event is administered one of the pharmaceutical compositions described herein to restore or recover the microbiome to a healthy microbiome. In some embodiments, the microbiome of the subject has one or more characteristics (identifying features) of a damaged microbiome after the enterotoxosis-inducing event. Examples of enterotoxosis-inducing events include exposure to antibiotics (e.g., treatment with vancomycin), infection, Clostridium difficile infection, misuse of alcohol, surgery, treatment with chemotherapeutic agents, treatment with immunosuppressants, traveler’s diarrhea, and inappropriate diet.

[0106] In addition, it is recognized that the microbiome can be modulated by exposure to any of the various classes of therapeutic agents, and that members of the gut microbiome metabolize structurally diverse drug molecules (see Zimmermann et al. Nature (2019) 570:462-471). In some embodiments, enterotoxosis-induced events involve exposure to one or more therapeutic agents that can be metabolized by the microbiome.

[0107] Examples of drug molecules that can be metabolized by the microbiome include steroids and hormone agonists (e.g., norethindrone acetate, levonorgestrel, megestrol acetate, betamethasone acetate, dexamethasone, drospirenone, norgestimate, finasteride), hormone antagonists (e.g., cyproterone acetate, bromocriptine mesylate, naloxone, mifepristone, bicalutamide), antidepressants and drugs associated with mental health (e.g., virazodone, fluoxetine, olanzapine, thiothixene, fluvoxamine maleate, paroxetine), Sulpiride, metitepine maleate, bupropion, ziprasidone mesylate, pimozide, fluoxetine, periciazine, paliperidone), antiviral agents (e.g., famciclovir, ritonavir, zidovudine (azt), nevirapine, amantadine), antiallergic / antihistamines (e.g., roxatidine acetate, clemastine fumarate, cetirizine, nizatidine, diphenylpyraline, tranilast), antidiarrheal agents (e.g., racecadotril, trimebutine maleate, loperamide), immunosuppressants (e.g., mycophenolate mofetil, deflazacort, Tacrolimus), antihypertensive drugs (e.g., olmesatran medoxomil, diltiazem flufenadine, telmisaratan, quinapril, trandolapril, benazepril, irbesartan, losartan, valsartan, enalapril maleate, benzthiazide, doxazosin mesylate, papaverine, lofexidine, verampimil, penbutrol sulfate, ramipril, carvedilol, nitrendipine), diabetes medications (e.g., linagliptin, trazamide, nateglinide, glipizide, gliclazide, Repaglinide), antipruritics (e.g., diflorasone diacetate, betamethasone valerate), cholesterol medications (e.g., fenofibrate, bezafibrate, ezetimibe, mevastatin, lovastatin), nonsteroidal anti-inflammatory drugs (e.g., fanprofazone, pranoprofen, oxaprozin, etodolac, ketrolactromethamine, colchicine, naproxen, celecoxib, diacetamate), muscle relaxants (e.g., carisoprodol, oxybutynin chloride, metaxalone, naphtopidil, sumatriptan succinate),Orphenadrine citrate, cremisole, trihexyphnidyl, alfuzosin, alprenolol, camylofin, chlormezanone, carbapentan citrate, phenazopyridine), antifungal agents (e.g., griseoulvin, mebendazole, voriconazole, fluconazole, itraconazole), sedatives (e.g., ramelteon, zaleplon, clonidine) (e.g., eszopiclone), central nervous system drugs (e.g., riluzole, galantamine, ergotamine tartrate, nicergoline, etopropazine, methylphenidate, methosiximide, oxcarbazepine, memantine, biperiden, methyserzide maleate, etozolamide, phenytoin sodium, idebenone, entacapone), anticoagulants (e.g., clopidrogrel sulfate) Sulfonate, sulfinpyrazone, warfarin, dipyridamole, anagrelide, trimetazidine, naphronyl oxalate), blood pressure raising drugs (e.g., digitoxin, digoxin, sotalol, acecainide), respiratory disease drugs (e.g., fenpiride), antiparasitic drugs (e.g., primaquine phosphate, mefloquine, rebamisole, artemisinin), chemotherapeutic agents (e.g., dasatinib, procarbine, cyclophosphamide, anastrozole, imiatinib, paclitaxel, capecitabine, melphalan), muscle tonics / enhancing agents (e.g., ergonovine maleate, neostigmine bromide), drugs associated with gastric / mucosal protection (e.g., rebamisole, Examples include pyrophosphate (e.g., metoprolol tartrate, ranitidine, pantoprazole, tenatoprazole), intestinal disorder medications (e.g., budesonide, dicyclomine, sulfasalazine, bisacodyl), uric acid inhibitors (e.g., febuxostate, indomethacin), acid fasteners (e.g., cimetidine, benzbromarone, omeprazole), erectile dysfunction medications (e.g., tadalafil, sildenafil citrate), analgesics (e.g., noscapine, rizatriptan benzoate), natural products (e.g., vinpocetine), skin disease medications (e.g., methoxsaline), immunostimulants (e.g., pyrotimod), antibiotics, and reproductive disorder medications (e.g., danazol).

[0109] The administration of antibiotics is associated with gastroenterotoxemia because the killing of symbiotic and / or commensal bacteria can lead to an overpopulation of opportunistic bacteria, causing disease. In some embodiments, antibiotics are administered to treat or prevent a bacterial infection or suspected bacterial infection. In some embodiments, antibiotics are administered in connection with surgery on the subject. In some embodiments, antibiotics are administered to the subject before (prophylactically) or after surgical procedures.

[0111] In some embodiments, the enterotoxemia-induced event is treated with antibiotics. In some embodiments, the enterotoxemia-induced event is treatment with antibiotics associated with surgery. In some embodiments, the antibiotic is vancomycin.

[0112] In some embodiments, the enterotoxosis-induced event is an infection, such as an infection caused by a virus, bacteria, fungus, yeast, parasite, or a combination thereof. In some embodiments, the subject is administered one or more therapeutic agents (e.g., antivirals, antibiotics, antifungals, antiparasitic agents, etc.) to treat the infection. In some embodiments, the enterotoxosis-induced event is a Clostridium difficile infection. Antibiotics typically used to treat Clostridium difficile infections include metronidazole, vancomycin, and fidaxomicin.

[0113] In some embodiments, the enterotoxosis-induced event is a gastrointestinal infection. In some embodiments, the subject is experiencing a gastrointestinal infection caused by, for example, Clostridium perfringens, Staphylococcus, Enterococcus faecium, Roseburia hominis, Raecalibacterium prausnitzii, Clostridioides difficile, Escherichia coli, Salmonella typhii, Vibrio cholerae, Shigella flexneri, Campylobacter, Peptostreptococcus, Yersinia, or Proteobacteria. In some embodiments, the enterotoxosis-induced event is traveler's diarrhea. Generally, traveler's diarrhea is a gastrointestinal disorder characterized by diarrhea, abdominal colic, nausea, vomiting, and / or fever, caused by exposure to an infectious pathogen during travel (e.g., typically eating contaminated food or drinking contaminated water).

[0114] In some embodiments, as described herein, the administration of one or more therapeutic agents for treating an infection, C. difficile infection, or traveler's diarrhea may contribute to gastrointestinal toxemia.

[0115] In some embodiments, the enterotoxosis-induced event is exposure to an antifungal agent.

[0120] Aspects of this disclosure relate to methods for protecting a target microbiome, the methods comprising administering a therapeutically effective amount of a pharmaceutical composition containing one or more purified bacterial strains. In some embodiments, the methods further comprise administering one or more additional doses of the pharmaceutical composition described herein. In some embodiments, the methods further comprise administering an antibiotic to the target prior to administering the pharmaceutical composition. In some embodiments, the methods further comprise administering vancomycin to the target prior to administering the pharmaceutical composition.

[0121] A number of factors can influence the composition of the gastrointestinal microbiota (e.g., diversity, abundance of specific populations). The compositions described herein may be used to protect the microbiota from such factors. As used herein, the term “protecting the microbiota” means preventing or minimizing disruption to the microbiota in question. In some embodiments, the compositions described herein help maintain the normal gastrointestinal microbiota in question. In some embodiments, the compositions described herein help maintain a healthy gastrointestinal microbiota. In some embodiments, by protecting the microbiota, microbiota-mediated disorders such as antibiotic-induced adverse reactions, Clostridium difficile infection, ulcerative colitis, Crohn's disease, and irritable bowel syndrome may be treated or prevented.

[0122] In some embodiments, the microbiome is considered protected if its composition (e.g., diversity, abundance of a particular population) does not substantially change after an event. In some embodiments, the microbiome is considered protected if its composition (e.g., diversity, abundance of a particular population) does not detectably change after an event. In some embodiments, the composition (e.g., diversity, abundance of a particular population) of the gastrointestinal microbiome changes by 10% or less (9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less) after an event. In some embodiments, events that may affect the composition of the microbiome are antibiotic treatment, attack by infectious agents (e.g., infection), and / or C. difficile infection.

[0123] In some embodiments, administration of the pharmaceutical compositions described herein protects the microbiome of the subject from antibiotic treatment. For example, the subject may be administered antibiotics to treat or prevent infection, according to the method provided herein, and the administration of these antibiotics (e.g., vancomycin) does not result in severe enterotoxemia. In some embodiments, administration of the pharmaceutical compositions described herein protects the microbiome of the subject from attack by infectious agents (e.g., infection). In some embodiments, administration of the pharmaceutical compositions described herein protects the microbiome of the subject from C. difficile infection. In some embodiments, the pharmaceutical compositions described herein protect the microbiome of the subject from C. difficile by increasing the recovery rate of the microbiome after administration of antibiotics to treat C. difficile infection. While we do not wish to be bound by any particular theory, it is thought that increasing the recovery rate of the microbiome after administration of antibiotics prevents C. difficile colonization (implantation) in the preferred depressions of the gastrointestinal tract. In some embodiments, the colonization of C. difficile is prevented by the colonization of one or more bacterial strains of the pharmaceutical composition or bacterial strains associated with the bacterial strains of the pharmaceutical composition in the C. difficile-preferred depressions of the gastrointestinal tract.

[0124] Aspects of this disclosure relate to methods for establishing a target microbiome, the methods comprising administering a therapeutically effective amount of a pharmaceutical composition containing one or more purified bacterial strains. In some embodiments, the methods further comprise administering one or more additional doses or amounts of the pharmaceutical composition described herein. In some embodiments, the methods further comprise administering an antibiotic to the target before administering the pharmaceutical composition. In some embodiments, the methods further comprise administering vancomycin to the target before administering the pharmaceutical composition.

[0125] In some embodiments, one or more bacterial strains of the pharmaceutical compositions provided herein colonize or re-colonize the target gastrointestinal tract or a portion thereof (e.g., the colon or cecum). Such colonization may also be referred to as transplantation or engraftment. In some embodiments, one or more bacterial strains of the compositions colonize the target gastrointestinal tract (e.g., the colon or cecum) after the naturally occurring microbiome has been partially or completely removed, for example, due to an enterotoxin-induced event. In some embodiments, one or more bacterial strains of the compositions colonize the target gastrointestinal tract (e.g., the colon or cecum) after the naturally occurring microbiome has been partially or completely removed by antibiotic (e.g., vancomycin) treatment. In some embodiments, one or more bacterial strains of the compositions colonize the gastrointestinal tract with an imbalance in the intestinal flora (e.g., the gastrointestinal tract treated with antibiotics). In some embodiments, all of the bacterial strains of the compositions colonize the gastrointestinal tract. In some embodiments, all of the bacterial strains of the compositions colonize the gastrointestinal tract with an imbalance in the intestinal flora. In some embodiments, multiple doses of the bacterial composition are administered to allow all of the bacterial strains of the composition to colonize the gastrointestinal tract. In some embodiments, multiple doses of the bacterial composition are administered to allow all of the bacterial strains of the composition to colonize the gastrointestinal tract in a state of intestinal symbiotic imbalance.

[0126] In some embodiments, one or more bacterial strains of the pharmaceutical composition can grow faster than other bacterial strains (e.g., pathogens) and thus colonize the microbiome. In some embodiments, the subject is treated with antibiotics, resulting in the removal of a large portion of the microbiome and creating a "blank slate" environment for both one or more bacterial strains of the composition and any other bacterial strains (e.g., pathogens). Therefore, although not limited to a specific mechanism, if both pathogens and one or more bacterial strains of the composition provided herein are present in the intestinal tract (e.g., colon or cecum), one or more bacterial strains of the composition provided herein grow faster than pathogens (e.g., have a shorter doubling time), preventing the accumulation of pathogens in the intestinal tract (e.g., colon or cecum) and enabling colonization of one or more bacterial strains of the composition. In some embodiments, one or more bacterial strains of the composition provided herein are superior to transplantation in the intestinal tract (e.g., colon or cecum), resulting in faster growth. In some embodiments, one or more bacterial strains of the compositions provided herein are superior in metabolizing nutrients present in the intestinal tract (e.g., colon or cecum), resulting in faster growth. In some embodiments, the compositions of bacterial strains provided herein prevent or inhibit the production of bacterial toxins by infectious agents, or prevent or inhibit the cytopathic or cytotoxic effects of such toxins. In some embodiments, the bacterial strains of the compositions provided herein can treat pathogenic infections due to synergistic effects between the bacterial strains. For this reason, in some embodiments, but not limited to, the combination of bacterial strains of the compositions provided herein acts synergistically, because the combination of strains is particularly suitable for the use of nutrients in the intestinal tract (e.g., colon or cecum) (e.g., through metabolic interactions) and / or the combination is superior for transplantation (e.g., by providing a favorable microenvironment). In some embodiments, one or more bacterial strains of the compositions described herein can colonize specific depressions in the intestinal tract (e.g., colon or cecum).In some embodiments, one or more bacterial strains of the compositions described herein can colonize specific depressions in the intestinal tract (e.g., the colon or cecum) that become available after antibiotic treatment.

[0127] In some embodiments, the pharmaceutical composition comprises seven bacterial strains, with at least two strains colonizing the control microbiome. In some embodiments, the pharmaceutical composition comprises seven bacterial strains, with at least four strains colonizing the target microbiome. In some embodiments, the pharmaceutical composition comprises seven bacterial strains, with each of the seven bacterial strains colonizing the target microbiome.

[0128] The degree of colonization of one or more bacterial strains may be determined, for example, by detecting the presence of one or more bacterial strains and / or by quantifying the abundance of one or more bacterial strains. In some embodiments, the bacterial strains of the pharmaceutical composition may be at least 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 5 4%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% colonize the target microbiome. In some embodiments, at least 25% of the bacterial strains of the pharmaceutical composition colonize the target microbiome. In some embodiments, at least 50% of the bacterial strains of the pharmaceutical composition colonize the target microbiome. In some embodiments, 100% of the bacterial strains of the pharmaceutical composition colonize the target microbiome. In some embodiments, the percentage of bacterial strains of the pharmaceutical composition colonizing the target microbiome increases by administering additional doses of the pharmaceutical composition. In one embodiment, it should be understood that the method provided herein provides better colonization of the bacterial strains of the pharmaceutical composition (e.g., higher number / percentage colonization and / or higher abundance) compared to colonization of the same pharmaceutical composition administered according to different methods. For this reason, in one embodiment, colonization is better because the pharmaceutical composition is administered according to a specific dosing regimen, dose, and / or antibiotic treatment regimen provided herein.

[0129] In some embodiments, the pharmaceutical composition contains eight bacterial strains, with at least two strains colonizing the target microbiome. In some embodiments, the pharmaceutical composition contains eight bacterial strains, with at least four strains colonizing the target microbiome. In some embodiments, the pharmaceutical composition contains eight bacterial strains, with each of the eight bacterial strains colonizing the target microbiome.

[0130] The degree of colonization of the microbiome by one or more bacterial strains of the pharmaceutical composition described herein may be based on the relative abundance of the bacterial strains of the pharmaceutical composition in the microbiome. For example, in some embodiments, at least 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53% of the bacterial strains of the target microbiome. 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% are bacterial strains of the pharmaceutical composition. In some embodiments, at least 25% of the bacterial strains detected in the target microbiome are bacterial strains of the pharmaceutical composition. In some embodiments, at least 50% of the bacterial strains detected in the target microbiome are the bacterial strains of the pharmaceutical composition. In some embodiments, the percentage of bacterial strains of the bacterial composition in the target microbiome increases by administering an additional dose of the pharmaceutical composition.

[0131] In some embodiments, the pharmaceutical compositions described herein result in the long-term colonization of one or more bacterial strains in the composition. In some embodiments, one or more bacterial strains of the pharmaceutical compositions described herein are detected in the target microbiome for an extended period. In some embodiments, one or more bacterial strains of the pharmaceutical compositions described herein colonize the target microbiome for an extended period. In some embodiments, one or more bacterial strains of the pharmaceutical compositions described herein are detected in the target microbiome for at least one week, two weeks, three weeks, four weeks, five weeks, or six weeks, seven weeks, eight weeks, nine weeks, ten weeks, eleven weeks, twelve weeks, three months, four months, five months, six months, seven months, eight months, nine months, ten months, eleven months, or one year after administration of the pharmaceutical composition.

[0132] In one embodiment, it should be understood that the method provided herein provides better colonization (e.g., higher number / percentage colonization and / or higher abundance) and more durable colonization of bacterial strains of the pharmaceutical composition compared to colonization of the same pharmaceutical composition administered according to a different method. Therefore, in one embodiment, the colonization is better and more durable because the pharmaceutical composition is administered according to a specific dosing regimen, amount, and / or antibiotic treatment regimen provided herein.

[0133] In one embodiment, it should be understood that the method provided herein provides more durable colonization of bacterial strains of the pharmaceutical composition compared to colonization of the same pharmaceutical composition administered according to a different method. Therefore, in one embodiment, the colonization is more durable because the pharmaceutical composition is administered according to a specific dosing regimen, dosage, and / or antibiotic treatment regimen provided herein.

[0134] The methods described herein involve administering one of the pharmaceutical compositions described herein to a subject in need thereof. As used herein, “subject,” “individual,” and “patient” are interchangeable and refer to vertebrates, preferably mammals such as humans. Mammals include, but are not limited to, human primates, non-human primates, or species of rodents, cattle, horses, dogs, or cats. In some embodiments, the subject is a human subject. In some embodiments, the human subject is a neonatal subject, a child subject, an adolescent subject, an adult subject, or an elderly subject. In some embodiments, the subject has or is at risk of having enterotoxosis, or has experienced or is at risk of experiencing an enterotoxosis-inducing event. In some embodiments, the subject has risk factors associated with enterotoxosis. In some embodiments, the subject has risk factors associated with microbiome disturbance.

[0135] Any of the compositions described herein may be administered to a subject in a therapeutically effective dose or a therapeutically effective amount. In some embodiments, the therapeutically effective dose is an amount sufficient to treat or prevent a disease or disorder. The terms “treat” or “medicate” mean to reduce or alleviate one or more of the symptoms associated with a disease or disorder (e.g., enterotoxemia).

[0136] In some embodiments, administering a therapeutically effective amount of any of the compositions described herein may prevent a disease or disorder (e.g., enterotoxemia), prevent disruption of the microbiome, and / or prevent colonization by a pathogen. The terms “prevent” or “prevent” encompass prophylactic administration and may, for example, reduce the incidence or likelihood of a disease or disorder. In some embodiments, the compositions reduce the incidence or likelihood of microbiome disruption. In some embodiments, the compositions reduce the incidence or likelihood of prevention of pathogen colonization. For example, in some embodiments, administration of the compositions provided herein results in a healthy microbiome, which provides an effect in subjects that reduces the incidence or likelihood of a disease or disorder. In some embodiments, administration of the compositions provided herein results in reduction or alleviation of one or more symptoms associated with a disease or disorder.

[0137] As used herein, the term “therapeutic effective dose” may be used interchangeably with the term “effective dose.” A therapeutic effective dose or effective dose of a composition, such as a pharmaceutical composition described herein, is any amount that produces a desired response or outcome in a subject, such as one described herein, which includes, but is not limited to, delaying the onset, halting the progression, at least one symptom of a disease or disorder (e.g., enterotoxosis), disruption of the microbiome, and / or reduction or mitigation of microbiome colonization by a pathogen. In some embodiments, a therapeutic effective dose is an amount sufficient to restore the microbiome, increase the recovery of the microbiome after an enterotoxosis-induced event, protect the microbiome, and / or colonize the microbiome of the subject. In some embodiments, a therapeutic effective dose is an amount sufficient to treat primary and / or secondary (recurrent) Clostridium difficile infection. In some embodiments, a therapeutic effective dose is an amount sufficient to treat or suppress a food allergy.

[0138] It should be understood that the term "effective dose" in relation to compositions containing bacterial strains may be expressed as the number of bacteria or CFUs administered. Furthermore, it should be understood that bacteria can grow once administered. Therefore, even relatively small doses of bacteria may have a therapeutic effect.

[0139] Furthermore, methods for determining whether a subject has or is at risk of having enterotoxemia, Clostridium difficile infection, or food allergies, or whether administration of any of the pharmaceutical compositions described herein is required, are also within the scope of this disclosure.

[0140] Aspects of this disclosure relate to bacterial strains having a 16S rDNA sequence that has sequence identity to any one of the nucleic acid sequences of the bacterial strains or species described herein. As those skilled in the art will understand, a 16S rDNA sequence represents a DNA sequence corresponding to a 16S rRNA sequence. The terms “identical” or “identity” percentage in the context of two or more nucleic acid or amino acid sequences refer to two or more sequences or subsequences that are the same. Two sequences are "substantially identical" if, when compared and aligned over a specified region, they have a specified percentage of identical amino acid residues or nucleotides over a specified region of the nucleic acid or amino acid sequence, or over the entire sequence (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%, or 99.9% sequence identity), measured using one of the subsequent sequence comparison algorithms or by manual alignment and visual inspection. Optionally, identity exists over a region of at least about 50 nucleotides in length, or more preferably over a region of 100 to 500 or 1000 nucleotides or longer. In some embodiments, identity exists over the length of the 16S rRNA or 16S rDNA sequence.

[0143] In some embodiments, the pharmaceutical composition comprises eight bacterial strains, each containing a 16S rDNA sequence having at least 97% sequence identity to the nucleic acid sequences indicated by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, and 8.

[0144] In some embodiments, the pharmaceutical composition comprises seven bacterial strains, each containing a 16S rDNA sequence having at least 97% sequence identity with the nucleic acid sequences indicated by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, and 8. In some embodiments, the pharmaceutical composition comprises seven bacterial strains, each containing a 16S rDNA sequence having at least 97% sequence identity with the nucleic acid sequences indicated by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, and 8. A composition containing a bacterial strain having a 16S rRNA sequence having 97% identity with the nucleic acid sequences indicated by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, and 8 may be referred to as "Composition VE416" or "VE416".

[0148] In addition, or separately, two or more sequences may be evaluated for alignment between them. In the context of two or more nucleic acid or amino acid sequences, the terms “alignment” or “alignment” percentage refer to two or more sequences or subsequences that are identical.

[0149] Two sequences are "substantially aligned" if, when compared and aligned over a specified region, they have a specified percentage of identical amino acid residues or nucleotides (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8%, or 99.9% identical) over a specified region or over the entire sequence, as measured by one of the subsequent sequence comparison algorithms or by manual alignment and visual inspection. Optionally, the alignment exists over a region of at least about 50 nucleotides in length, or more preferably over a region of 100 to 500 or 1000 nucleotides or longer. In some embodiments, the identity exists over the length of the 16S rRNA or 16S rDNA sequence.

[0150] In sequence comparison, typically one sequence serves as a reference sequence, against which the test sequence is compared. Methods for aligning sequences for comparison are well known in the art. For example, see the local homology algorithm of Smith and Waterman (1970) Adv. Appl. Math. 2:482c, the homology alignment algorithm of Needleman and Wunsch, J. Mol. Biol. 48:443, 1970, the similarity search of Pearson and Lipman. Proc. Natl. Acad. Sci. USA 85:2444, 1988, computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group. Madison. WI), or manual alignment and visual inspection (see, for example, Brent et al., Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (Ringbou ed., 2003)). Two examples of suitable algorithms for determining sequence identity percentage and sequence similarity are the BLAST algorithm and the BLAST 2.0 algorithm, which are described in Altschul et al., Nuc. Acids Res. 25:3389-3402, 1977 and Altschul et al., J. Mol. Biol. 215:403-410, 1990.

[0182] Compositions, such as pharmaceutical compositions, for administration to a target are also within the scope of this disclosure. In some embodiments, the composition comprises one of the bacterial strains described herein.

[0183] In one embodiment, the present disclosure provides a pharmaceutical composition comprising one of the bacterial strains described herein. In some embodiments, the pharmaceutical composition comprises a pharmaceutically acceptable excipient. In some embodiments, the pharmaceutical composition is formulated for oral administration. In some embodiments, the pharmaceutical composition is formulated for rectal administration. In some embodiments, the pharmaceutical composition is formulated for delivery to the intestines. In some embodiments, the pharmaceutical composition is formulated for delivery to the colon.

[0184] In some embodiments, the pharmaceutical composition described herein comprises one or more bacterial strains. In some embodiments, the pharmaceutical composition may be lyophilized. In some embodiments, the pharmaceutical composition is in the form of a capsule. In some embodiments, the pharmaceutical composition further comprises a pH-sensitive composition comprising one or more enteric-coated polymers.

[0185] In some embodiments, one or more bacterial strains of the pharmaceutical composition are spray-dried. The spray-drying process refers to creating a dry powder from a liquid containing the bacterial composition. (See, for example, Ledet et al., Spray-Drying of Pharmaceuticals in "Lyophilized Biologics and Vaccines," pp. 273-194, Springer). Generally, this process involves rapidly drying the bacterial composition with a high-temperature gas.

[0186] Any of the compositions described herein, including pharmaceutical compositions and food products, wherein the bacterial strain is in any form, e.g., an aqueous form such as a solution or suspension, embedded in a semi-solid form, in powder form, or in lyophilized form. In some embodiments, the composition or bacterial strain is lyophilized. In some embodiments, a subset of the bacterial strain is lyophilized. Methods for lyophilizing compositions, particularly compositions containing bacteria, are well known in the art. See, for example, U.S. Patent Nos. 3,261,761, 4,205,132, PCT Publications WO2014 / 029578 and WO2012 / 098358, which are incorporated herein by whole reference. The bacteria may be lyophilized as a combination, and / or the bacteria may be lyophilized separately and combined before administration. A bacterial strain may be combined with a pharmaceutical excipient before being combined with another bacterial strain, or multiple lyophilized bacteria may be combined while they are in their lyophilized form, and this bacterial mixture may then be combined with a pharmaceutical excipient at the time of combination. In some embodiments, the bacterial strain is a lyophilized cake. In some embodiments, the composition containing one or more bacterial strains is a lyophilized cake.

[0187] In some embodiments, one or more bacterial strains of the composition, including pharmaceutical compositions and food products, are spray-dried. In some embodiments, a subset of bacterial strains is spray-dried. The spray-drying process refers to creating a dry powder from a liquid containing a bacterial composition (see, for example, Ledet, et al., Spray Draying of Pharmaceuticals in "Lyophilized Biologics and Vaccines," pp. 273-294, Springer). Generally, this process involves rapidly drying the bacterial composition with a hot gas. Bacterial strains may be combined with pharmaceutical excipients before being combined with other bacterial strains, or multiple spray-dried bacteria may be combined while in the spray-dried form, and this mixture of bacteria may then be combined with pharmaceutical excipients at the time of combination.

[0188] Bacterial strains can be produced using fermentation techniques well known in the art. In some embodiments, bacteria are grown or produced using anaerobic fermenters, which can support the rapid growth of anaerobic bacterial species. The anaerobic fermenter may be, for example, a stirred-tank reactor or a disposable wave bioreactor. Culture media such as BL medium and EG medium, or similar media without animal components, can be used to support the growth of bacterial species. Bacterial products can be purified and concentrated from the fermentation broth by conventional techniques such as centrifugation and filtration, and optionally dried and freeze-dried by techniques well known in the art.

[0189] In some embodiments, the live bacterial product may be formulated for administration as a pharmaceutical composition. As used herein, the term “pharmaceutical composition” means a product resulting from a mixture or combination of at least one active ingredient, such as one of the bacterial strains described herein, and one or more inactive ingredients, which may include one or more pharmaceutically acceptable excipients.

[0190] An “acceptable” excipient is an excipient that must be compatible with the active ingredient and must not be harmful to the recipient. In some embodiments, pharmaceutically acceptable excipients are selected based on the intended route of administration of the composition; for example, a composition for oral or nasal administration may contain different pharmaceutically acceptable excipients than a composition for rectal administration. Examples of excipients include sterile water, saline, solvents, bases, emulsifiers, suspending agents, surfactants, stabilizers, fragrances, aromatics, excipients, vehicles, preservatives, binders, diluents, isotonic modifiers, mitigating agents, bulking agents, disintegrants, buffers, coatings, lubricants, colorants, sweeteners, thickeners, and solubilizers.

[0191] The pharmaceutical compositions of the present invention can be prepared according to methods that are well known and routinely practiced in the art (see, for example, Remington: The Science and Practice of Pharmacy, Mack Publishing Co., 20th ed. 2000). The pharmaceutical compositions described herein may further contain any carrier or stabilizer in the form of a lyophilized formulation or an aqueous solution. Acceptable excipients, carriers, or stabilizers may include, for example, buffers, antioxidants, preservatives, polymers, chelating agents, and / or surfactants. The pharmaceutical compositions are preferably manufactured under GMP conditions. This pharmaceutical composition can be used orally, nasally, or parenterally in the form of, for example, capsules, tablets, pills, sachets, liquids, powders, granules, fine granules, film-coated formulations, pellets, lozenges, sublingual formulations, chewables, oral formulations, pastes, syrups, suspensions, elixirs, emulsions, topical preparations, ointments, plasters, poultices, transdermal absorption systems, lotions, inhalants, aerosols, injections, suppositories, etc. In some embodiments, this pharmaceutical composition can be used by injection, such as intravenous, intramuscular, subcutaneous, or intradermal administration.

[0192] In some embodiments, the composition containing the bacterial strain is formulated for oral delivery. In some embodiments, the composition containing the bacterial strain is formulated for delivery to the intestines (e.g., the small intestine and / or colon). In some embodiments, the composition containing the bacterial strain may be formulated using an enteric coating to increase the survival of bacteria in the harsh environment of the stomach. The enteric coating is a coating that resists the action of gastric juice in the stomach, allowing the bacteria of the composition within it to pass through the stomach and enter the intestines. The enteric coating may readily dissolve upon contact with intestinal fluid, so that the bacteria encapsulated in the coating are released into the intestinal tract. The enteric coating may consist of commercially available polymers and copolymers well known in the art, such as EUDRAGIT (Evonik Industries). (See, for example, Zhang, AAPS PharmSciTech, 2016, 17(1), 56-67).

[0193] The composition containing the bacterial strain may also be formulated for rectal delivery to the intestines (e.g., the colon). Therefore, in some embodiments, the composition containing the bacterial strain may be formulated for delivery by suppositories, colonoscopy, endoscopy, sigmoidoscopy, or enema. Pharmaceutical preparations or formulations, and in particular pharmaceutical preparations for oral administration, may contain additional components that enable efficient delivery of the composition of this disclosure to the intestines (e.g., the colon). A variety of pharmaceutical preparations can be used to allow delivery of the composition to the intestines (e.g., the colon). Examples include pH-sensitive compositions, more specifically, buffered sachet formulations or enteric polymers that release their contents when the pH becomes alkaline after passing through the stomach. When a pH-sensitive composition is used in the formulation of a pharmaceutical preparation, the pH-sensitive composition is preferably a polymer whose pH threshold for decomposition of the composition is about 6.8 to about 7.5. Such a numerical range is the range in which the pH shifts to the alkaline side in the distal part of the stomach, and is therefore suitable for use in delivery to the colon. Furthermore, it should be understood that different parts of the intestine (e.g., the duodenum, jejunum, ileum, cecum, colon, and rectum) have different biochemical and chemical environments. For example, parts of the intestine have different pH levels, which allows for targeted delivery by compositions having specific pH sensitivity. Therefore, the compositions provided herein may be formulated for delivery to the intestine or specific parts of the intestine (e.g., the duodenum, jejunum, ileum, cecum, colon, and rectum) by providing formulations with appropriate pH sensitivity. (See, for example, Villena et al., Int J Pharm 2015, 487(1-2):314-9).

[0194] Pharmaceutical compositions for administration by additional or alternative routes are also within the scope of this disclosure. In some embodiments, the pharmaceutical compositions are formulated for sublingual administration. In some embodiments, the pharmaceutical compositions are formulated for administration by injection.

[0195] In some embodiments, the pharmaceutical composition may include additional components that enable efficient delivery of the composition of the disclosure to a desired site, such as the gastrointestinal tract (e.g., the colon).

[0196] In some embodiments, the pharmaceutical composition includes an adjuvant associated with providing benefits in the treatment of allergies. In some embodiments, the pharmaceutical composition includes one or more components of an oral immunotherapy agent, a transdermal immunotherapy agent, or a sublingual immunotherapy agent.

[0197] Another embodiment of a pharmaceutical preparation useful for the delivery of a composition to the intestines (e.g., the colon) ensures delivery to the colon by delaying the release of the contents (e.g., bacterial strain) by approximately 3 to 5 hours, corresponding to the small intestinal transit time. In one embodiment of a pharmaceutical preparation for delayed release, a hydrogel is used as a shell. The hydrogel hydrates and swells upon contact with gastrointestinal fluid, resulting in the effective release of the contents (primarily in the colon). Delayed-release dosage forms include drug-containing compositions having a material that coats or selectively coats the drug or active ingredient to be administered. Examples of such selective coating materials include in vivo degradable polymers, gradual hydrolyzable polymers, gradual water-soluble polymers, and / or enzymatically degradable polymers. A wide variety of coating materials are available for efficiently delaying release, and these include, for example, cellulosic polymers such as hydroxypropylcellulose, acrylic polymers and copolymers such as methacrylic polymers and copolymers, and vinyl polymers and copolymers such as polyvinylpyrrolidone.

[0198] Additional examples of pharmaceutical compositions that allow delivery to the intestines (e.g., the colon) include bioadhesive compositions that adhere specifically to the colonic mucosa (e.g., polymers described in U.S. Patent No. 6,368,586), and compositions that incorporate protease inhibitors to protect biopharmaceutical preparations in particular within the gastrointestinal tract from degradation due to protease activity.

[0199] Another example of a system that enables delivery to the intestines (e.g., the colon) is a system that delivers a composition to the colon by a pressure change that releases the contents by utilizing the pressure change caused by gas production during bacterial fermentation in the distal part of the stomach. Such systems are not particularly limited, and a more specific example is a capsule in which the contents are dispersed in a suppository base and coated with a hydrophobic polymer (e.g., ethylcellulose).

[0200] Further examples of systems that enable the delivery of compositions to the intestines (e.g., the colon) include compositions comprising a coating that can be removed by enzymes present in the gastrointestinal tract (e.g., the colon), such as carbohydrate hydrolases or carbohydrate reductases. Such systems are not particularly limited, and more specific examples include systems using food ingredients such as non-starch polysaccharides, amylose, xanthan gum, and azopolymers.

[0201] The compositions provided herein can also be delivered to specific target areas, such as the intestines, by delivery via an opening (e.g., a nasal tube) or by surgery. In addition, compositions provided herein, formulated for delivery to specific areas (e.g., the cecum or colon), may be administered by tube (e.g., directly into the small intestine). Combining mechanical delivery methods, such as tubes, with chemical delivery methods, such as pH-specific coatings, makes it possible to deliver the compositions provided herein to desired target areas (e.g., the cecum or colon).

[0202] A composition containing bacteria is formulated into a pharmaceutically acceptable dosage form by conventional methods known to those skilled in the art. The dosing regimen is adjusted to provide the optimal desired response (e.g., prophylactic or therapeutic effect). In some embodiments, the dosage form of the composition is a tablet, pill, capsule, powder, granule, solution, or suppository. In some embodiments, the pharmaceutical composition is formulated for oral administration. In some embodiments, the pharmaceutical composition contains a bacterial strain and is formulated so that the bacteria or a portion of them remain viable after passing through the stomach of the subject. In some embodiments, the pharmaceutical composition is formulated for rectal administration, for example, as a suppository. In some embodiments, the pharmaceutical composition is formulated for delivery to the intestine or a specific region of the intestine (e.g., the colon) by providing a suitable coating (e.g., a pH-specific coating, a coating that can be degraded by a target-region-specific enzyme, or a coating that can bind to receptors present in the target region).

[0203] The dosage of the active ingredient in the pharmaceutical composition of the present invention can be varied to obtain an amount of the active ingredient effective in achieving a desired pharmaceutical response for a particular subject, composition, and mode of administration without being toxic or having adverse effects on the subject. The selected dosage level is based on a variety of factors, including the activity of the particular composition of the present invention used, the route of administration, the time of administration, the duration of treatment, other drugs, compounds, and / or materials used in combination with the particular composition used, the age, sex, weight, condition, general health, and prior medical history of the subject being treated, and similar factors.

[0204] A physician, veterinarian, or other trained practitioner may begin administering the pharmaceutical composition at a level lower than necessary to achieve the desired therapeutic effect and gradually increase the dose until the desired effect (e.g., treatment of Clostridium difficile infection, treatment of allergies, or modulation of one or more immune responses associated with allergies) is achieved. In general, the effective dose of the composition of the present invention for the prophylactic treatment of groups of people such as those described herein varies depending on many different factors, including the route of administration, the physiological state of the subject, whether the subject is human or animal, other drugs administered, and the desired therapeutic effect. To optimize safety and efficacy, the dose may need to be titrated. In some embodiments, the administration regimen requires oral administration of any dose of one of the compositions described herein. In some embodiments, the administration regimen requires oral administration of multiple doses of one of the compositions described herein. In some embodiments, any of the compositions described herein is administered to a subject once, twice, three times, four times, five times, five times, six times, seven times, eight times, nine times, at least ten times, at least eleven times, at least twelve times, at least thirteen times, at least fourteen times, or more. In some embodiments, any of the compositions described herein is administered to a subject in multiple doses at regular intervals, such as daily, every two days, every three days, every four days, every five days, every six days, weekly, every two weeks, monthly, every two months, every three months, every four months, every five months, every six months, or more. In some embodiments, one dose of any of the compositions described herein is administered, and a second dose of the composition is administered the following day (e.g., on consecutive days). In some embodiments, one dose of any of the compositions described herein is administered, and each of the additional doses of the composition is administered on consecutive days (e.g., the first dose on day one, the second dose on day two, the third dose on day three, etc.).

[0205] In one embodiment, the Disclosure provides a method comprising administering multiple doses of the pharmaceutical composition. In some embodiments, the Disclosure provides a method comprising administering an antibiotic (e.g., vancomycin) followed by multiple doses of the pharmaceutical composition. In some embodiments, multiple doses of the pharmaceutical composition described herein enhance the colonization (engraftment) of one or more bacterial strains of the pharmaceutical composition compared to a single dose of the pharmaceutical composition. In some embodiments, multiple doses of the pharmaceutical composition described herein enhance the recovery of one or more bacterial strains of the pharmaceutical composition compared to a single dose of the pharmaceutical composition. In some embodiments, multiple doses of the pharmaceutical composition increase the abundance of one or more bacterial strains of the pharmaceutical composition compared to a single dose of the pharmaceutical composition. In some embodiments, multiple doses of the pharmaceutical composition described herein increase the number of subjects to which all of the bacterial strains of the pharmaceutical composition colonize compared to a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical composition described herein results in the establishment of one or more bacterial strains of the pharmaceutical composition (e.g., up to 6 months) compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical composition described herein results in the establishment of all bacterial strains of the pharmaceutical composition (e.g., 6 months) compared to administration of a single dose of the pharmaceutical composition. Furthermore, it should be understood that combinations of the results described may occur with multiple doses. For example, in some embodiments, administration of multiple doses of the pharmaceutical composition described herein results in increased establishment (engraftment) and increased recovery rate of one or more bacterial strains of the pharmaceutical composition compared to administration of a single dose of the pharmaceutical composition.

[0206] In some embodiments, administration of multiple doses of the pharmaceutical composition described herein enhances the colonization (engraftment) of one or more bacterial strains of the pharmaceutical composition compared to administration of a single dose of the pharmaceutical composition. As shown in Figures 6 and 7, administration of multiple doses of the pharmaceutical composition enhances the colonization (engraftment) of each bacterial strain of the pharmaceutical composition and increases their abundance. In some embodiments, administration of a single dose of the pharmaceutical composition results in the same or similar level of engraftment (e.g., total bacteria) as administration of multiple doses of the pharmaceutical composition, but the engraftment may be occupied by only one bacterial strain or a subset of bacterial strains of the pharmaceutical composition.

[0207] Any of the methods described herein may further include administering an antibiotic to the subject before administering the pharmaceutical composition described herein. In some embodiments, the antibiotic is vancomycin, fidaxomicin, or ridinirazole. Non-limiting examples of antibiotics that may be used in any of the methods provided herein include the cephalosporin antibiotics cefaloxine, cefuroxime, cefadroxil, cefazolin, cephalothin, cefaclor, cephamandol, cefoxitin, cefprodil, ceftoviprole, clindamycin, ceftriaxone, cefotaxime, cefazolin, cefoperazone, cefuroxime, cefmetazole, fluoroquinolone, ciprofloxacin, Levaquin, phloxine, tequin, avelox, norflox, tetracy This includes cinnamide, minocycline, oxytetracycline, doxycycline, amoxicillin, ampicillin, penicillin V, dicloxacillin, benzylpenicillin, carbenicillin, vancomycin, and methicillin), ertapenem, doripenem, imipenem / cilastatin, meropenem, clavulanate, tazobactam, piperacillin, ceftriaxone, cefotaxime, cefazolin, fluoroquinolone, imipenem, meropenem, metronidazole, fidaxomyxin, or ridinirazole. In some embodiments, any of the methods described herein may further include administering vancomycin to the subject before administering the pharmaceutical composition described herein. In some embodiments, the method does not include administering vancomycin to the subject before administering the pharmaceutical composition described herein. Vancomycin administration is known to alter the composition of the human gut microbiota. See, for example, Reijnders et al. Cell Metabolism (2016) 24(1):63-72. While we do not wish to be bound by any particular theory, it is thought that vancomycin administration may help the colonization of the bacterial strain(s) of the pharmaceutical composition described herein by eliminating other microorganisms present in the gastrointestinal tract, for example.

[0208] In some embodiments, vancomycin is administered to the subject as a single dose. In some embodiments, vancomycin is administered to the subject in multiple doses.
