FIELD

[0002] The present disclosure relates to pharmaceutical compositions and methods suitable for treating multiple sclerosis.

BACKGROUND

[0003] Mammals harbor diverse microbial species in their gastrointestinal (GI) tracts.

Interactions between these microbes and between microbes and the host, e.g. the host immune system, shape a microbiota. A healthy microbiota provides the host with multiple benefits, including colonization resistance to a broad spectrum of pathogens, essential nutrient biosynthesis and absorption, and immune stimulation that maintains a healthy gut epithelium and an appropriately controlled systemic immunity. An unbalanced microbiota (also called 'dysbiosis' or disrupted symbiosis) may lose its function and results in increased susceptibility to pathogens, altered metabolic profiles, or induction of proinflammatory signals that can lead to local or systemic inflammation or autoimmunity. Additionally, such a disrupted microbiota may be infected by incoming pathogen or pathogens, which can cause pain, diarrhea, gas, and constipation among other symptoms. Hence, the intestinal microbiota plays a significant role in the pathogenesis of many disorders such as pathogenic infections of the gut.

[0004] Implantation or administration of human colonic microbiota into the bowel of a sick patient is called Fecal Microbiota Transplantation (FMT), also commonly known as fecal bacteriotherapy. FMT is believed to repopulate the gut with a diverse array of microbes that control key pathogens by creating an ecological environment inimical to their proliferation and survival. It represents a therapeutic protocol that allows a fast reconstitution of a normal compositional and functional gut microbial community.

[0005] FMT has been used to treat Clostridium difficile infection (CDI). FMT has also been suggested in treating other gut infective agents such as E. coli and Vancomycin resistant Enterococci (VRE). It entails infusions through a colonoscope, an enema or via a nasojejunal tube of human microbiota either in the form of homogenised stool, or cultured stool components such as Clostridia, to implant in the colon and thereby displace or eradicate pathogenic bacteria, e.g., C. difficile.

[0006] Without being bound to any theory, multiple sclerosis (MS) is considered by some as a disabling autoimmune disease of the central nervous system. In multiple sclerosis the immune system attacks the protective myelin sheath of nerve fibers. Damage to the myelin sheath slows down or stops nerve signaling and causes miscommunication between the brain and spinal cord and other parts of the body. The disease can progress to permanent damage of the nerves. Multiple sclerosis consists of four disease types, including clinically isolated syndrome (CIS), relapsing-remitting multiple sclerosis (RRMS), primary progressive multiple sclerosis (PPMS), and secondary progressive multiple sclerosis (SPMS). Symptoms of multiple sclerosis vary depending on the amount of nerve damage, location of damage and severity of the disease. Attacks can last for days, weeks, or months, followed by periods of remission. People who suffer from severe multiple sclerosis may lose the ability to walk. Other symptoms can include loss of balance, muscle spasms, numbness, motor difficulties, tremors and limb weakness. Additional symptoms can affect the bowel or bladder. These include constipation and stool leakage, difficulty urinating, frequent urination, and urine leakage. A subject with multiple sclerosis can also suffer from double vision, eye discomfort, rapid eye movements and vision loss. Multiple sclerosis may further cause memory loss, difficulty solving problems, depression, hearing loss, slurred speech and difficulty with chewing and swallowing.

[0007] Existing treatments for multiple sclerosis involve medication that can decrease or diminish symptoms and slow down the disease. Multiple sclerosis affects women more than men and is most commonly diagnosed between ages 20 to 40. The hospitalization rates of multiple sclerosis patients decreased by 75% in 2011, in comparison to 1984, however, hospitalization rates of multiple sclerosis patients remain higher than hospitalization rates of the general population. See, Marrie et al., Neurology 2014; 83 : 929-937. Thus, there is a need for more effective treatments for multiple sclerosis that are easier to administer. SUMMARY

[0030] As used herein, "isolated" or "purified" refers to a bacterium or other entity or substance that has been (1) separated from at least some of the components with which it was associated when initially produced (whether in nature or in an experimental setting), and/or (2) produced, prepared, purified, and/or manufactured by the hand of man. Isolated or purified bacteria can be separated from at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, or more of the other components with which they were initially associated.

[0031] As used herein, "cytotoxic" activity or bacterium includes the ability to kill a bacterial cell, such as a pathogenic bacterial cell. A "cytostatic" activity or bacterium includes the ability to inhibit, partially or fully, growth, metabolism, and/or proliferation of a bacterial cell, such as a pathogenic bacterial cell.

[0036] As used herein, "Shannon Diversity Index" refers to a diversity index that accounts for abundance and evenness of species present in a given community using the formula

where H is Shannon Diversity Index, R is the total number of species in the community, and pi is the proportion of R made up of the z ^' th species. Higher values indicate diverse and equally distributed communities, and a value of 0 indicates only one species is present in a given community. For further reference, see Shannon and Weaver, (1949) The mathematical theory of communication. The University of Illinois Press, Urbana. 117pp.

[0037] As used herein, "antibiotic" refers to a substance that is used to treat and/or prevent bacterial infection by killing bacteria, inhibiting the growth of bacteria, or reducing the viability of bacteria. [0038] As used herein, an "intermittent dosing schedule" means that that a therapeutic composition is administered for a period of time followed by a period of time (a treatment period) where treatment with such therapeutic composition is withheld (a rest period).

Intermittent dosing regimens can be expressed as treatment period in days or weeks/rest period in days or weeks. For example, a 4/1 intermittent dosing schedule refers to an intermittent dosing schedule where the treatment period is four weeks/days and the rest period is one week/day.

[0039] As used herein, a "continuous dosing schedule" refers to a dosing schedule where a therapeutic composition is administered during a treatment period without a rest period. Throughout the treatment period of a continuous dosing schedule, a therapeutic composition can be administered, for example, daily, or every other day, or every third day. On a day when a therapeutic composition is administered, it can be administered in a single dose, or in multiple doses throughout the day.

[0040] As used herein, "dosing frequency" refers to the frequency of administering doses of a therapeutic composition in a given time. Dosing frequency can be indicated as the number of doses per a given time, for example, once per day, once a week, or once in two weeks.

[0041] As used herein, "dosing interval" refers to the amount of time that elapses between multiple doses being administered to a subject.

[0042] Multiple sclerosis is a pro-inflammatory demyelinating disease of the central nervous system. Damage to the myelin forms scar tissue which lead to distorted or interrupted nerve impulses traveling to and from the brain and spinal cord, producing a wide variety of symptoms.

[0043] Multiple sclerosis symptoms include bladder dysfunction (e.g., difficulty urinating, frequent urination, urine leakage), bladder infection, bowel dysfunction (e.g., constipation and stool leakage), depression, dizziness, vertigo, fatique, itching, pain, sexual discomfort, tremors, walking difficulties, muscle spasms, brain lesions, double vision, eye discomfort, rapid eye movements, vision loss, memory loss, difficulty solving problems, hearing loss, slurred speech, difficulty with chewing or difficulty with swallowing. Multiple symptoms may co-exist in the same patient.

[0044] Multiple sclerosis occurs most often in people ages 20 to 40, although the disease may afflict people of any age. It affects women more frequently than men and appears to run in some families.

[0045] Different types of multiple sclerosis exist. As used herein, "clinically isolated syndrome" refers to a disease form characterized by the first episode of neurologic symptoms caused by inflammation and damage to myelin. The episode, which must last for at least 24 hours, is characteristic of multiple sclerosis but fails to meet the diagnosis criteria of multiple sclerosis. The subject may or may not subsequently develop multiple sclerosis. Subjects with clinically isolated syndrome can present with lesions on the brain which increase the chances of the subject having a subsequent episode and developing multiple sclerosis.

[0046] As used herein, "relapsing-remitting multiple sclerosis" refers to the most common disease type, characterized by defined episodes involving new or more advanced neurologic symptoms. During periods in between episodes subjects show signs of partial or complete remission. Eighty-five percent (85%) of patients present with relapsing-remitting multiple sclerosis.

[0047] As used herein, "primary progressive multiple sclerosis" refers to a subject with continuous worsening neurologic function overtime with remissions or obvious relapses. There may be temporary plateaus during which the disease does not progress. Patients are identified as active at the time of relapses or new MRI lesions or not active. Primary progressive multiple sclerosis includes patients who were previously diagnosed with progressive-relapsing multiple sclerosis.

[0048] As used herein, "secondary progressive multiple sclerosis" refers to a subject with worsening neurologic function overtime. Secondary progressive multiple sclerosis follows an initial relapsing-remitting course.

[0049] Several theories have been proposed for the cause of multiple sclerosis. There is some evidence to suggest that the body's immune system reacts to an environmental or infectious agent in genetically susceptible individuals causing inflammation and demyelination in the central nervous system.

[0050] The most common symptoms of multiple sclerosis are bladder dysfunction, bladder infection, bowel dysfunction, depression, dizziness, vertigo, fatigue, itching, pain, sexual discomfort, tremors, walking difficulties, and muscle spasms. These symptoms occur in between periods when the symptoms go away (remissions) and are referred to as "flare-ups", "relapse", or "exacerbation". A relapse can last at least 24 hours and are separated from the previous relapse by at least 30 days. Signs of a relapse can include a subject with multiple sclerosis experiencing fatigue, tingling, brain fog, muscle spasms, or depression. A relapse can last for days, weeks, or months, followed by periods of remission.

[0051] People suffering from acute multiple sclerosis attacks may be treated with

corticosteroids. Prednisone, methylprednisolone, budesonide, and hydrocortisone are corticosteroids used to reduce inflammation. They can be given orally, intravenously, through an enema, or in a suppository, depending on the location of the inflammation. Corticosteroids can cause side effects such as weight gain, acne, facial hair, hypertension, diabetes, mood swings, and increased risk of infection, so doctors carefully monitor patients taking these medications.

[0052] Multiple sclerosis symptoms can be severe enough that the person must be hospitalized. In fact, after the first hospitalization for diagnosis of MS, patients usually experience hospitalization several times due to repeated attacks of the disease. The patient may need a special diet, feeding through a vein, medications, or sometimes surgery.

[0053] Recently, relapsing-remitting multiple sclerosis patients were identified as having a distinct gut microbiota compared to healthy patients as described in Chen, et al, Multiple Sclerosis patients have a distinct gut microbiota compared to healthy controls, Scientific Reports 2016; (6): 1-10. Many chronic diseases and disorders of the GI tract have chronic infection/infestation as their underlying pathological conditions {e.g., multiple sclerosis). In one aspect, the present disclosure includes and relates to the use of a fecal microbiota, one or more microbial species therefrom, an active fragment or component therefrom for the treatment and/or prophylaxis of various disease states {e.g., multiple sclerosis) related to the presence of 'abnormal' microflora in the GI tract. An active fragment of a bacterium can be any active molecule isolated from such bacteria by any known method for

preparing/identifying active fragments of bacteria and proteins secreted from bacteria. Such methods include but are not limited to the following: sonication, osmotic shock, detergent lysis, high pressure, transfer appropriate DNA to other organisms, such as bacteria, plant or animal that is then used as a feed additive as described previously. In one aspect, an active fragment or component of a bacterium is selected from the group consisting of a mycolate or a derivative thereof, a polysaccharide, a lipoglycan, a small peptide, a thiopeptide, a protein, a nucleic acid molecule, a metabolite, a cell wall component, or any combination thereof. In one aspect, an active fragment is a protein or a secretion. In another aspect, an active fragment is a secreted protein.

"Non-living material" does not include an excipient, e.g., a pharmaceutically inactive substance, such as a cryoprotectant, added to a processed fecal material. "Biological material" refers to the living material in fecal material, and includes microbes including prokaryotic cells, such as bacteria and archaea (e.g., living prokaryotic cells and spores that can sporulate to become living prokaryotic cells), eukaryotic cells such as protozoa and fungi, and viruses. In one embodiment,

"biological material" refers to the living material, e.g., the microbes, eukaryotic cells, and viruses, which are present in the colon of a normal healthy human. In an aspect, a therapeutic composition provided or administered herein comprises an extract of human feces where the composition is substantially odorless. In an aspect, a therapeutic composition provided or administered herein comprises fecal material or a fecal floral preparation in a lyophilized, crude, semi-purified or purified formulation.

[0086] In an aspect, a fecal microbiota in a therapeutic composition comprises highly refined or purified fecal flora, e.g., substantially free of non-floral fecal material. In an aspect, a fecal microbiota can be further processed, e.g., to undergo microfiltration before, after, or before and after sieving. In another aspect, a highly purified fecal microbiota product is ultra- filtrated to remove large molecules but retain the therapeutic microflora, e.g., bacteria.

[0087] In another aspect, a fecal microbiota in a therapeutic composition used herein comprises or consists essentially of a substantially isolated or a purified fecal flora or entire (or substantially entire) microbiota that is (or comprises) an isolate of fecal flora that is at least about 90%, 91 %, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or 99.9% isolated or pure, or having no more than about 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% or 1.0% or more non-fecal floral material; or, a substantially isolated, purified, or substantially entire microbiota as described in Sadowsky et al, WO 2012/122478 Al, or as described in Borody et al, WO 2012/016287 A2.

[0088] In an aspect, a fecal microbiota in a therapeutic composition comprises a donor's substantially entire or non-selected fecal microbiota, reconstituted fecal material, or synthetic fecal material. In another aspect, the fecal microbiota in a therapeutic composition comprises no antibiotic resistant population. In another aspect, a therapeutic composition comprises a fecal microbiota and is largely free of extraneous matter {e.g., non-living matter including acellular matter such as residual fiber, DNA, RNA, viral coat material, non-viable material; and living matter such as eukaryotic cells from the fecal matter's donor).

[0089] In an aspect, a fecal microbiota in a therapeutic composition used herein is derived from disease-screened fresh homologous feces or equivalent freeze-dried and reconstituted feces. In an aspect, a fresh homologous feces does not include an antibiotic resistant population. In another aspect, a fecal microbiota in a therapeutic composition is derived from a synthetic fecal composition. In an aspect, a synthetic fecal composition comprises a preparation of viable flora which preferably in proportional content, resembles normal healthy human fecal flora which does not include antibiotic resistant populations. Suitable microorganisms may be selected from the following: Acinetobacter, Akkermansia,

Bacteroides, Eubacterium, Fusobacterium, Propionibacterium, Lactobacillus, Ruminococcus, Escherichia coli, Gemmiger, Clostridium, Desulfomonas, Peptostreptococcus,

Bifidobacterium, Collinsella, Coprococcus, Dorea, and Ruminococcus.

[0090] In an aspect, a therapeutic composition used in a treatment disclosed herein comprises a sterile fecal filtrate or a non-cellular fecal filtrate. In one aspect, a sterile fecal filtrate originates from a donor stool. In another aspect, a sterile fecal filtrate originates from cultured microorganisms. In another aspect, a sterile fecal filtrate comprises a non-cellular non-parti culate fecal component. In one aspect, a sterile fecal filtrate is made as described in WO2014/078911, published May 30, 2014. In another aspect, a sterile fecal filtrate is made as described in Ott et al, Gastroenterology 152:799-911(2017).

[0091] In one aspect, a fecal filtrate comprises secreted, execreted or otherwise liquid components or a microbiota, e.g., biologically active molecules (BAMs), which can be antibiotics or anti- inflammatories, are preserved, retained or reconstituted in a flora extract.

[0092] In one aspect, an exemplary therapeutic composition comprises starting material from a donor from a defined donor pool, where this donor contributes a stool that is centrifuged, then filtered with very high-level filtration using e.g., either metal sieving or Millipore filters, or equivalent, to ultimately permit only cells of bacterial origin to remain, e.g., often less than about 5 micrometers diameter. After the initial centrifugation, the solid material is separated from the liquid, and the solid is then filtered in progressively reducing size filters and tangential filters, e.g., using a Millipore filtration, and optionally, also comprising use of nano-membrane filtering. The filtering can also be done by sieves as described in WO

2012/122478, but in contrast using sieves that are smaller than .0120 mm, down to about .0110 mm, which ultimately result in having only bacterial cells present.

[0093] The supernatant separated during centrifugation is now taken and filtered

progressively in a filtering, e.g., a Millipore filtering or equivalent systems, to end up with liquid which is finely filtered through an about 0.22 micron filter. This removes all particulate matter including all living matter, including bacteria and viruses. The product then is sterile, but the aim is to remove the bacteria but to keep their secretions, especially antimicrobial bacteriocins, bacteria-derived cytokine-like products and all accompanying Biologically Active Molecules (BAMs), including: thuricin (which is secreted by bacilli in donor stools), bacteriocins (including colicin, troudulixine or putaindicine, or microcin or subtilosin A), lanbiotics (including nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, cinnamycin), lacticins and other antimicrobial or anti-inflammatory compounds.

[0094] In one aspect, a therapeutic composition used here comprises a reconstituted fecal flora consisting essentially of a combination of a purified fecal microbiota and a non-cellular fecal filtrate. In another aspect, a therapeutic composition used here comprises a purified fecal microbiota supplemented with one or more non-cellular non-particulate fecal components. In one aspect, a therapeutic composition used here comprises one or more non- cellular non-particulate fecal components. In one aspect, one or more non-cellular non- particulate fecal components comprise synthetic molecules, biologically active molecules produced by a fecal microorganism, or both. In another aspect, one or more non-cellular non- particulate fecal components comprise biologically active proteins or peptides,

micronutrients, fats, sugars, small carbohydrates, trace elements, mineral salts, ash, mucous, amino acids, nutrients, vitamins, minerals, or any combination thereof. In one aspect, one or more non-cellular non-particulate fecal components comprise one or more biologically active molecules selected from the group consisting of bacteriocin, lanbiotic, and lacticin. In another aspect, one or more non-cellular non-particulate fecal components comprise one or more bacteriocins selected from the group consisting of colicin, troudulixine, putaindicine, microcin, and subtilosin A. In one aspect, one or more non-cellular non-particulate fecal components comprise one or more lanbiotics selected from the group consisting of thuricin, nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, and cinnamycin. In another aspect, one or more non-cellular non-particulate fecal components comprise an anti-spore compound, an antimicrobial compound, an anti-inflammatory compound, or any combination thereof. In a further aspect, one or more non-cellular non-particulate fecal components comprise an interleukin, a cytokine, a leukotriene, an eicosanoid, or any combination thereof.

[0095] In another aspect, a treatment method provided here comprises the use of both fecal bacterial cells, e.g., a partial or a complete representation of the human GI microbiota, and an isolated, processed, filtered, concentrated, reconstituted and/or artificial liquid component (e.g., fecal filtrate) of the flora (the microbiota) which comprises, among others ingredients, bacterial secretory products such as e.g., bacteriocins (proteinaceous toxins produced by bacteria, including colicin, troudulixine or putaindicine, or microcin or subtilosin A), lanbiotics (a class of peptide antibiotics that contain a characteristic polycyclic thioether amino acid lanthionine or methyllanthionine, and unsaturated amino acids dehydroalanine and 2-aminoisobutyric acid; which include thuricin (which is secreted by bacilli in donor stools), nisin, subtilin, epidermin, mutacin, mersacidin, actagardine, cinnamycin), a lacticin (a family of pore-forming peptidic toxins) and other antimicrobial or anti-inflammatory compounds and/or additional biologically active molecules (BAMs) produced by bacteria or other microorganisms of the microbiota, and/or which are found in the "liquid component" of a microbiota.

[0096] In one aspect, a fecal bacteria-based therapeutic composition is used concurrently with a fecal non-cellular filtrate-based therapeutic composition. In another aspect, a patient is treated with a first fecal non-cellular filtrate-based therapeutic composition before being given a second fecal bacteria-based therapeutic composition, or vice versa. In a further aspect, a treatment method comprises three steps: first, antibiotic pre-treatment to non- selectively remove infectious pathogen(s); second, a fecal non-cellular filtrate-based treatment step to further suppress selected infectious pathogen(s); and third, giving the patient a fecal bacteria-based therapeutic composition to re-establish a functional intestinal microbiome.

[0097] In an aspect, a therapeutic composition is combined with other adjuvants such as antacids to dampen bacterial inactivation in the stomach, (e.g., Mylanta, Mucaine, Gastrogel). In another aspect, acid secretion in the stomach could also be pharmacologically suppressed using H2-antagonists or proton pump inhibitors. An example H2-antagonist is ranitidine. An example proton pump inhibitor is omeprazole. In one aspect, an acid suppressant is administered prior to administering, or in co-administration with, a therapeutic composition.

[0098] In an aspect, a therapeutic composition is in the form of: an enema composition which can be reconstituted with an appropriate diluent; enteric-coated capsules; enteric-coated microcapsules; acid-resistant tablet; acid-resistant capsules; acid-resistant microcapsules; powder for reconstitution with an appropriate diluent for naso-enteric infusion or

colonoscopic infusion; powder for reconstitution with appropriate diluent, flavoring and gastric acid suppression agent for oral ingestion; powder for reconstitution with food or drink; or food or food supplement comprising enteric-coated and/or acid-resistant microcapsules of the composition, powder, jelly, or liquid.

[0099] In an aspect, a treatment method effects a cure, reduction of the symptoms, or a percentage reduction of symptoms of multiple sclerosis. The change of flora is preferably as "near-complete" as possible and the flora is replaced by viable organisms which will crowd out any remaining, original flora. Typically the change in enteric flora comprises introduction of an array of predetermined flora into the gastro-intestinal system, and thus in a preferred form the method of treatment comprises substantially or completely displacing pathogenic enteric flora in patients requiring such treatment. [00100] In another aspect, a therapeutic composition can be provided together with a pharmaceutically acceptable carrier. As used herein, a "pharmaceutically acceptable carrier" refers to a non-toxic solvent, dispersant, excipient, adjuvant, or other material which is mixed with a live bacterium in order to permit the formation of a pharmaceutical composition, e.g., a dosage form capable of administration to the patient. A pharmaceutically acceptable carrier can be liquid (e.g., saline), gel or solid form of diluents, adjuvant, excipients or an acid resistant encapsulated ingredient. Suitable diluents and excipients include pharmaceutical grades of physiological saline, dextrose, glycerol, mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, magnesium carbonate, and the like, and combinations thereof. In another aspect, a therapeutic composition may contain auxiliary substances such as wetting or emulsifying agents, stabilizing or pH buffering agents. In an aspect, a therapeutic composition contains about l%-5%, 5%-10%, 10%-15%, 15-20%, 20%-25%, 25- 30%, 30-35%, 40-45%, 50%-55%, l%-95%, 2%-95%, 5%-95%, 10%-95%, 15%-95%, 20%- 95%, 25%-95%, 30%-95%, 35%-95%, 40%-95%, 45%-95%, 50%-95%, 55%-95%, 60%- 95%, 65%-95%, 70%-95%, 45%-95%, 80%-95%, or 85%-95% of active ingredient. In an aspect, a therapeutic composition contains about 2%-70%, 5%-60%, 10%-50%, 15%-40%, 20%-30%, 25%-60%, 30%-60%, or 35%-60% of active ingredient.

[00101] In an aspect, a therapeutic composition can be incorporated into tablets, drenches, boluses, capsules or premixes. Formulation of these active ingredients into such dosage forms can be accomplished by means of methods well known in the pharmaceutical formulation arts. See, e.g., U.S. Pat. No. 4,394,377. Filling gelatin capsules with any desired form of the active ingredients readily produces capsules. If desired, these materials can be diluted with an inert powdered diluent, such as sugar, starch, powdered milk, purified crystalline cellulose, or the like to increase the volume for convenience of filling capsules.

[00102] In an aspect, conventional formulation processes can be used to prepare tablets containing a therapeutic composition. In addition to the active ingredients, tablets may contain a base, a disintegrator, an absorbent, a binder, and a lubricant. Typical bases include lactose, sugar, sodium chloride, starch and mannitol. Starch is also a good disintegrator as is alginic acid. Surface-active agents such as sodium lauryl sulfate and dioctyl sodium sulphosuccinate are also sometimes used. Commonly used absorbents include starch and lactose. Magnesium carbonate is also useful for oily substances. As a binder there can be used, for example, gelatin, gums, starch, dextrin, polyvinyl pyrrolidone and various cellulose derivatives. Among the commonly used lubricants are magnesium stearate, talc, paraffin wax, various metallic soaps, and polyethylene glycol. [00103] In an aspect, for preparing solid compositions such as tablets, an active ingredient is mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, or other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a composition of the present invention. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing a desired amount of an active ingredient (e.g., at least about 10 ⁵ , 10 ⁶ , 10 ⁷ , 10 ⁸ , 10 ⁹ , 10 ¹⁰ , 10 ¹¹ , 10 ¹² , or 10 ¹³ cfu). A therapeutic composition used herein can be flavored.

[00104] In an aspect, a therapeutic composition can be a tablet or a pill. In one aspect, a tablet or a pill can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, a tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

[00105] In an aspect, a therapeutic composition can be a drench. In one aspect, a drench is prepared by choosing a saline-suspended form of a therapeutic composition. A water-soluble form of one ingredient can be used in conjunction with a water-insoluble form of the other by preparing a suspension of one with an aqueous solution of the other. Water- insoluble forms of either active ingredient may be prepared as a suspension or in some physiologically acceptable solvent such as polyethylene glycol. Suspensions of water- insoluble forms of either active ingredient can be prepared in oils such as peanut, corn, sesame oil or the like; in a glycol such as propylene glycol or a polyethylene glycol; or in water depending on the solubility of a particular active ingredient. Suitable physiologically acceptable adjuvants may be necessary in order to keep the active ingredients suspended. Adjuvants can include and be chosen from among the thickeners, such as

carboxymethylcellulose, polyvinyl pyrrolidone, gelatin and the alginates. Surfactants generally will serve to suspend the active ingredients, particularly the fat-soluble propionate- enhancing compounds. Most useful for making suspensions in liquid nonsolvents are alkylphenol polyethylene oxide adducts, naphthalenesulfonates, alkylbenzene-sulfonates, and the polyoxyethylene sorbitan esters. In addition many substances, which affect the hydrophilicity, density and surface tension of the liquid, can assist in making suspensions in individual cases. For example, silicone anti-foams, glycols, sorbitol, and sugars can be useful suspending agents.

[00106] In an aspect, a therapeutic composition comprises non-pathogenic spores of one or more, two or more, three or more, or four or more Clostridium species selected from the group consisting of Clostridium absonum, Clostridium argentinense, Clostridium baratii, Clostridium botulinum, Clostridium cadaveris, Clostridium carnis, Clostridium ce latum, Clostridium chauvoei, Clostridium clostridioforme, Clostridium cochlearium, Clostridium fallax, Clostridium felsineum, Clostridium ghonii, Clostridium glycolicum, Clostridium haemolyticum, Clostridium hastiforme, Clostridium histolyticum, Clostridium indolis, Clostridium irregulare, Clostridium limosum, Clostridium malenominatum, Clostridium novyi, Clostridium oroticum, Clostridium paraputrifwum, Clostridium perfringens,

Clostridium piliforme, Clostridium putrefaciens, Clostridium putrifwum, Clostridium sardiniense, Clostridium sartagoforme, Clostridium scindens, Clostridium septicum,

Clostridium sordellii, Clostridium sphenoides, Clostridium spiroforme, Clostridium sporogenes, Clostridium subterminale, Clostridium symbiosum, Clostridium tertium, Clostridium tetani, Clostridium welchii, and Clostridium villosum.

[00107] In an aspect, a therapeutic composition comprises purified, isolated, or cultured viable non-pathogenic Clostridium and a plurality of purified, isolated, or cultured viable non-pathogenic microorganisms from one or more genera selected from the group consisting of Collinsella, Coprococcus, Dorea, Eubacterium, and Ruminococcus .

In another aspect, a therapeutic composition comprises at most about 10 ⁵ , 10 ⁶ , 10 ⁷ , 10 ⁸ , 10 ⁹ , 10 ¹⁰ , 10 ¹¹ , 10 ¹² , 10 ¹³ or 10 ¹⁴ cells or total cell count.

[00111] In one aspect, a therapeutic composition is formulated as an oral capsule, microcapsule, tablet, or pill. In another aspect, a capsule, microcapsule, tablet, or pill is adapted for enteric delivery. In a further aspect, a capsule, microcapsule, tablet, or pill is an enteric capsule, microcapsule, tablet, or pill. In another aspect, a capsule, microcapsule, tablet, or pill comprises an enteric coating, is acid resistant, or both.

EXAMPLES

Example 1. Preparation of fecal microbiota.

[00228] Fecal microbiota is prepared essentially according to protocols published in US2014/0147417 or WO2014/152484. Summarized below is an exemplary protocol.

[00229] Potential fecal microbiota donors are screened according to a list of criteria used to exclude unsuitable donors. Potential fecal microbiota donors are excluded if they have received antibiotics, laxatives, diet pills, immunomodulators or chemotherapy in the preceding three months. Potential fecal microbiota donors are excluded if they have a history of all known infectious diseases, morbid obesity, diabetes, irritable bowel syndrome, inflammatory bowel disease, chronic diarrhea, constipation, colorectal polyps or cancer, a compromised immune system, metabolic syndromes, chronic fatigue syndrome, major GI surgery, or other diseases or conditions potentially associated with specific changes in fecal microbiota. Potential fecal microbiota donors are excluded if they exhibit positive laboratory tests for C-reactive protein, erythrocyte sedimentation rate, hepatitis A, hepatitis B, hepatitis C, human immunodeficiency virus, human T-lymphotropic virus, or syphilis. Potential fecal microbiota donors are excluded if they exhibit a positive test for stool ova, parasites, and/or viruses. Potential fecal microbiota donors are excluded if they engage in high-risk sexual behaviors, have been incarcerated, or received any tattoos or body piercings in areas that have had disease epidemics within the past three months.

[00230] Donor fecal material (fresh feces) is collected in a sterilized container, and then it is transferred to a blender. Approximately 500-1000 mL 0.9% saline solution is added to the blender and thoroughly mixed with the fecal sample. The resulting suspension is filtered at least 4 times through strainers prior to collecting a final suspension. The final suspension is centrifuged in 50 mL tubes at 1200 x g for 3 minutes. The supernatant is discarded and the pellet is gently resuspended in approximately 50 mL of sterile 0.9% saline solution. The centrifugation and resuspension steps are repeated 2 to 4 additional times. Upon the final centrifugation, the supernatant is discarded. If the fecal microbiota is to be used immediately, the resultant pellet is resuspended in 1.5-volumes of 0.9% saline solution by gently mixing. If the fecal microbiota is to be stored, the resultant pellet is resuspended in 10%) sterile glycerol and stored at -80 degrees Centigrade. If fecal microbiota are frozen, they are warmed to room temperature prior to administration to a patient

Example 2. Treatment of multiple sclerosis induced constipation in wheelchair-bound patients.

[00231] A 30-year old male patient presents with constipation and a recent history of multiple sclerosis. The patient suddenly develops symptoms of vertigo, impaired

concentration and mood alterations post a surgery. The symptoms further lead to neuritis and trigeminal neuralgia and result in a multiple sclerosis diagnosis which was confirmed by MRI. Prior to the fecal microbiome therapy, the patient receives interferon treatments which do not improve his condition. Fecal microbiome therapy is administered for constipation, resulting in complete resolution. The patient's MS symptoms progressively improve and the ability to walk is regained, facilitating catheter removal. The patient remains asymptomatic 15-years post-fecal microbiome therapy without relapse. Follow-up MRI 15-years post-fecal microbiome therapy reports a halting of disease progression and no evidence of active disease.

[00232] A 29-year old male presents with severe, chronic constipation, and atypical multiple sclerosis. Bilateral leg paralysis and urinary incontinence leaves the patient wheelchair-bound with a indwelling urinary catheter. Fecal microbiome therapy results in dramatic resolution of constipation, allowing daily defecation with ease. The patient also reports a rapid and progressive improvement in multiple sclerosis symptoms. Improvements include the patient regaining the ability to walk, defecate and urinate normally, and subsequent urinary catheter removal. The patient remains asymptomatic 7-years post-fecal microbiome therapy.

[00233] An 80-year old female patient presents with severe chronic constipation, and a history of atypical multiple sclerosis manifesting as a severe muscular weakness, leaving the patient wheelchair-bound. Fecal microbiome therapy treatment results in rapid improvement of constipation and increased energy levels. At eight months post-Fecal microbiome therapy the patient reports complete resolution of bowel symptoms and neurological improvement. The patient gains the ability to walk long distances unassisted. Two years post-Fecal microbiome therapy, the patient remains asymptomatic. Example 3. Treatment of multiple sclerosis and irritable bowel syndrome (IBS).

[00234] A 39-year old male patient, with longstanding irritable bowel syndrome and

Multiple Sclerosis, that has been dormant and stable for two years, is treated with Fecal microbiome therapy. The patient's symptoms include muscle fatigue, loss of balance, walking difficulty with much weakness and required support, and slurred speech. The patient also shows demyelination on MRI which later improves on a repeat MRI.

[00235] The patient is treated with fecal microbiome therapy through the colonoscope into the ascending colon, followed by nine enemas over the next week to increase the bacterial load. The patient initially responds for two months and shows no symptoms of either IBS or MS. The patient regains energy and has no feelings of nausea. Further, the patient passes two formed motions per day, and he is able to walk without support after treatment. This marks the only period of good health experienced by the patient over many years. However, after two months of improvement, his symptoms started recurring and he reverted to where his colonic flora was in the first place. The patient was prescribed

Rifaximin and low dose probiotics, which had little effect on his multiple sclerosis and IBS symptoms.

Example 4. Treatment of multiple sclerosis.

[00236] A 57-year old male patient with multiple sclerosis is treated with fecal microbiome therapy. The patient suffers from lethargy, weakness, weight loss, altered bowel habits, and urinary incontinence. Three months after Fecal microbiome therapy treatment, the patient experiences increased energy and his constipation is deemed to be resolved. However, eight months after his fecal microbiome therapy treatment the initial symptoms reoccur. The patient begins a course of antibiotic pre-treatment in preparation for a repeat colonic fecal microbiome therapy.

[00237] Additional treatments followed by home infusions to continue the previously gained improvements are performed.

Example 5. Treatment of multiple sclerosis.

[00238] A female patient, suffering from multiple sclerosis and constipation is prescribed fecal microbiome therapy pre-treatment consisting of Rifaximin and Vancomycin. The pre-treatment improves the patient's multiple sclerosis symptoms and the patient experiences resolution of constipation, increased energy, and ability to move affected muscles more strongly. Following pre-treatment and cessation of antibiotics, the patient receives fecal microbiome therapy. Approximately one and a half months after the fecal microbiome therapy, the patient reports experiencing an improvement in energy, decreased bloating and incontinence, and improved balance. The patient continues receiving fecal microbiome therapy to treat gastrointestinal symptoms and her multiple sclerosis attributed weakness. In summary, fecal microbiome therapy improves the patient' s gastrointestinal symptoms and weakness as a result of multiple sclerosis.

Example 6. Treatment of multiple sclerosis.

[00239] A 27 year old patient, suffers from multiple sclerosis, a stiff and weak right leg, a 4/5 weakness for right hip flexion, a 3-4/5 weak knee flexion, a 4+/5 ankle dorsiflexion, and 4+/5 weakness for right hand abduction weakness in right shoulder. The patient is prescribed fecal microbiome therapy.

Example 7. Oral capsule treatment protocol for multiple sclerosis.

[00240] Patients are divided into four groups (Groups 1 to 4). Group 1 patients are administered a pre-treatment of antibiotics (e.g., Vancomycin and Metronidazole). Group 2 receives no antibiotics. Both Groups 1 and 2 receive a pre-colonoscopy bowel prep followed by capsule fecal microbiome therapy. Groups 3 and 4 receive no bowel prep while Group 3, but not Group 4, also receives an antibiotic pretreatment. A single capsule contains between 10 ⁹ and 10 ¹² viable cells. Capsules are administered for 18 weeks as follows: two capsules twice-a-day for 14 days, two capsules twice-a-day every other day for 14 days, 4 capsules twice-a-week for 14 days, and 4 capsules once-a-week (e.g., each Monday) for 12 weeks. High dose capsules (total cell count of about 10 ¹² ) are used in loading doses (also called treatment doses) for the initial 4 weeks. Lower dose capsules (total cell count of about 10 ⁹ ) are used in maintenance doses for the subsequent 14 weeks. In patients receiving antibiotic pretreatment, capsules are administered one day after ceasing antibiotics. Patient symptoms are observed and clinical examination is performed before, during and post oral capsule treatment. Pre, during and post-treatment DNA metagenomics (2-4 days; 1 week; 6 weeks; 12 weeks) are also carried out. The capsule treatments reverse patient symptoms and result in a clinically normal urge and defecation.
