[0004] Recent developments in the fields of microbiome and genomics research have provided evidence that the bacterial composition of the human gut has a fundamental impact on human health, disease development and progression. However, much remains unknown regarding the relationship between the microbiome and the host, the functional and metabolic changes in the host due to microbiome composition, and the potential for developing bacterial compositions for therapeutic use. For example, although there are established genetic components that contribute to the risk of inflammatory diseases such as allergies and asthma, environmental factors including microbial exposure and microbiome composition play a key role in the pathogenesis of these diseases. Data from clinical trials indicate that the gut microbiome of young children who will eventually develop allergies and asthma differs in bacterial species composition and immunomodulatory activity. There is concern about the rising incidence of allergic diseases in general, with asthma being one of the fastest growing global concerns and a vexing problem. As there is no cure for any of these allergic diseases, they have become a major public health challenge and billions of dollars are spent on treating the symptoms. For example, asthma represents a huge cost burden in the United States alone, exceeding $56 billion annually, of which nearly $20 billion is spent on standard treatments with variable efficacy and potentially serious side effects. As a result, the expansion of treatment options such as immunomodulatory microbial compositions aimed at preventing allergic disease would address a significant unmet need, especially in the disproportionately affected pediatric population.

The data shown represent standard curves created using pure bacterial DNA (10, 1, 0.1, 0.01, 0.001, 0.0001 and 0.00001 nanograms (ng)) of 50 ng total DNA (strain DNA + fecal DNA) of three strains diluted in a fecal DNA background. When analyzing human samples to determine the amount of strain DNA [e.g., A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185) and L. crispatus (DSM 33187)], control samples can be run and analyzed in parallel to ensure that the DNA primers used in the experiment can adequately amplify the DNA of the bacterial strain. [Figure 20]Figure 20 shows a schematic flow chart of the optimized ultra-large scale growth and production process for A. muciniphila (DSM 33213) in a culture volume of 3500 L. 19.2 mL of working cell bank (WCB) A. muciniphila (DSM 33213) was thawed in an anaerobic chamber and inoculated into 1 L of reduced NAGT medium (2% v / v inoculation rate) in a 1 L bottle (2001) in an anaerobic chamber. The culture was stopped when OD585>1 or when the culture was grown for 48 h. The entire culture in 2001 was used to inoculate 16 L of medium (5% v / v inoculation rate) in a 20 L fermenter (2002). The culture was stopped when OD585>1.5 or when the culture was grown for 48 h. 15 L of the culture in 2002 was used to inoculate 300 L of medium (5% v / v inoculation rate) in a 300 L fermenter (2003). The culture was stopped when OD585>1.5 or when the culture was grown for 48 hours. 240 L as specified in Table 15 was prepared. 100 L of sugar feed was added to a 3500 L fermenter (2004). 300 L of the culture in 2002 was used to inoculate 3500 L of medium (8-10% v / v inoculation rate) in 2004. When the glucose concentration dropped below 2 g / L, an additional 100 L of sugar feed was added. The culture was stopped when OD585>2.5 or when the culture was grown for 72 hours. The entire culture in 2004 was then centrifuged under anaerobic atmosphere and harvested as biomass. 100 L of filter-sterilized, degassed cryoprotectant, as defined in Table 17, was mixed with the biomass in an anaerobic gas-purged mixing tank. The biomass containing the cryoprotectant was lyophilized (frozen and dried) and ground. At each step, the medium used for bacterial culture was sterilized (autoclaved at 121° C.) and degassed with N2H2CO2 (90:5:5) before use. The sugar components (N-acetylglucosamine and glucose) were prepared separately from the other NAGT medium components. The sugar feed was filter-sterilized, degassed, and added to the other NAGT medium components to obtain the complete medium.

[0044] Further provided herein are oral formulations of pharmaceutical compositions that can be frozen. Such frozen formulations can be administered to a subject, such as a human subject, in a frozen state. In some cases, such frozen formulations can be popsicles, ice creams, or other frozen formulations.

[0045] In various embodiments herein, the pharmaceutical composition of the present disclosure may be in a liquid suspension for oral administration to a subject. Such liquid suspension may be aliquoted into a specific volume to obtain a unit dose of such oral dosage form. Such a unit dose may have a volume of about 0.25, 0.5, 1, 2, 3, 5, or 10 mL. In some cases, a unit dose of the pharmaceutical composition herein has a volume of about 1 mL. Such pharmaceutical composition may include bacterial symbionts, cryoprotectants, antioxidants, aqueous buffer solutions (which may be from a liquid cell suspension). Such cell suspension may be tested for quality control to ensure that it contains a specific number of metabolically active cells per bacterial strain as described herein.

[0046] In some embodiments, the present disclosure provides pharmaceutical compositions formulated in a unit dose for oral administration to a subject. Such oral formulations contain approximately 5×10 6 of each of the bacterial strains A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185), and L. crispatus (DSM 33187). 8 CFU, about 20% v / v glycerol, about 0.1% w / w L-cysteine, and a PBS buffer containing 137 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, and 1.8 mM KH2PO4. Such oral formulations may have a total volume of about 1 mL.

[0047] The present specification provides a method for producing a pharmaceutical composition described herein. In some cases, such pharmaceutical compositions include a bacterial symbiont comprising one or more bacterial species and / or strains. In some cases, such one or more bacterial strains may include any one or more of Lactobacillus crispatus (DSM 33187), A. muciniphila (DSM 33213), and / or F. prausnitzii (DSM 33185). The production of such pharmaceutical compositions may include several steps. Such steps may include preparation of growth medium, inoculation and culturing, harvesting of bacterial cells, and combining of the bacterial symbiont by combining prepared bacterial strain batches used in the pharmaceutical composition. In some cases, such production methods may be used to produce pharmaceutical compositions for clinical use in human subjects.

[0048] The disclosed method for producing a bacterial symbiont can include medium preparation, which can include dissolving various dried medium components, such as salts, vitamins, antioxidants, etc., in USP grade water for injection. After complete dissolution, the pH of the medium can be adjusted to ensure optimal growth of each bacterial cell. The pH-adjusted medium can then be transferred to a biosafety cabinet and sterilized. In various cases, the microbial symbiont herein can include one or more anaerobic bacterial strains. In such cases, the medium can be transferred to an anaerobic chamber containing an atmosphere of N2H2CO2 (about 90:5:5) to reduce prior to inoculation with anaerobic bacteria.

[0049] The manufacturing method herein may include making a starting culture of the bacterial strain / species. Such a method may include making a starting culture of the bacterial strain to be included in the pharmaceutical composition by using a specific volume from each flask containing filtered medium, transferring such volume to a sterile pre-reduced screw cap tube, and then transferring the thawed bacterial cells using a stock solution from a cell bank containing the respective bacterial cells. When anaerobic bacterial cells are used, the starting culture may be cultured under anaerobic conditions at about 37° C. for about 12-16 hours. After the specific incubation time, the starting culture may be visually inspected for growth (turbidity) and, if bacterial growth is confirmed, may be transferred into an additional larger culture flask for further cell growth. After about 12, 18, 24, 30 hours of incubation, the cell density and optical density of the cell culture medium may be measured. Such measurements may be performed at a specified OD 600 This can be done by measuring the absorbance of the cell suspension at 600 nanometers to ensure that the absorbance falls within the range of OD. 600 The value or range of OD can be specific to the bacterial strain. For example, each bacterial strain shown in Table 1 has a specific OD 600 Such an OD may have a value or a range. 600 The OD can range from about 0.5 to about 1.5, from about 0.7 to about 1.3, or from about 0.9 to about 1.1. 600 After the assay, the bacterial cells can be harvested using various techniques such as centrifugation.

[0050] In some cases, appropriate centrifugation parameters can be selected for cell recovery. For example, in some cases, any of the bacterial strains listed in Table 1 can be recovered using parameters including spinning at about 5,000-10,000×g for about 20-60 minutes at about 4° C., ensuring that the cells can be separated from the supernatant. After centrifugation, the resulting cell pellet can be placed back into an anaerobic environment (e.g., an anaerobic chamber) and the clarified culture supernatant can be completely removed from such pellet, for example, using a sterile serological pipette. The cell pellet can then be mixed by resuspending it in a concentrated pre-reduced cryoprotectant solution. In some cases, such a suspension can be about 20-40 times more concentrated than the growing cell suspension, and the pre-reduced cryoprotectant solution can be about 20% v / v glycerol or another cryoprotectant. The concentrated cell suspension can then be dispensed into aliquots, such as pre-reduced, pre-labeled 2 mL screw-cap cryovials, and transferred to pre-labeled storage boxes at about -70° C. or below. If such bacterial cells are to be used in a pharmaceutical composition, specification testing can be performed about 3 days after manufacture and initial storage at about -70° C. or below.

[0051] The present disclosure provides a method for producing a cell population or cell batch of one or more species and / or strains used in a pharmaceutical composition. In various cases, any of the bacterial strains shown in Table 1 can be used in the production methods described herein. In certain cases, one or more of the strains Lactobacillus crispatus (DSM 33187), A. muciniphila (DSM 33213) and / or F. prausnitzii (DSM 33185) (Table 2) can be used to produce a cell batch used in a pharmaceutical composition. In such cases, the present disclosure provides a method for producing such a cell batch.

[0052] The present specification provides a method for producing a Lactobacillus crispatus (DSM 33187) cell batch that can be used in the pharmaceutical compositions described herein. Such a method can include preparing a Lactobacillus crispatus (DSM 33187) cell culture medium. Such a medium can be vMRS medium or bouillon vMRS broth. In some cases, such a medium is not HiMedia vMRS broth. Such a medium is specific for the Lactobacillus crispatus (DSM 33187) strain and can include vMRS powder and dipotassium phosphate (K2HPO4). In such cases, the medium for growing and culturing Lactobacillus crispatus (DSM 33187) cells can include about 250-300 g of vMRS powder and dipotassium phosphate (K2HPO4). In a particular case, such a medium may contain about 273 g of vMRS powder and about 12.5 g of dipotassium phosphate (K2HPO4) and about 4.9 L of water. The pH of such a vMRS medium may be adjusted to about 6.5±0.1, for example, using 5 M hydrochloride solution or glacial acetic acid. The medium may then be filtered, reduced to anaerobic conditions, transferred to a starting culture tube containing, for example, a stock L. crispatus (DSM 33187) solution, and incubated at 37° C. for about 16-20 hours. After incubation and growth, the absorbance of the cell culture at 600 nm may be measured and measured in triplicate to ensure that the absorbance of the working cell suspension is within the range of about 0.8 to about 1.6, preferably about 1.0 to 1.4. The contents of the culture flask can be centrifuged and the remaining cell pellet resuspended in 25 mL of sterile PBS containing antioxidants and cryoprotectant (e.g., 20% v / v glycerol) and then combined to obtain a homogenous cell suspension. The L. crispatus (DSM 33187) cell suspension can be aliquoted, for example, into cryovials to obtain the final cell concentration.The final Lactobacillus crispatus (DSM 33187) cell concentration was approximately 5 × 10 per unit dose. 8 ~about 10 10 Such a unit dose may have a volume of about 1 mL. In such a case, the unit dose may be about 5×10 viable cells of L. crispatus (DSM 33187). 8 The composition may contain viable Lactobacillus crispatus (L. crispatus) (DSM 33187) cells.

[0053] Further provided herein is a method for producing an A. muciniphila (DSM 33213) cell batch that can be used in the pharmaceutical compositions described herein. Such a method can include preparing an A. muciniphila (DSM 33213) cell culture medium. In some cases, such an A. muciniphila (DSM 33213) culture medium can be a modified NAGT medium. Such a modified NAGT medium can include soytone or N-acetylglucosamine (NAG), or both soytone and NAG. In some cases, such a modified NAGT medium can be free of magnesium, calcium, glucose, or combinations thereof. In some cases, the modified NAGT medium can result in improved cell growth. Such improved cell growth can be about 30%, 35%, 40%, 45%, or 50% higher compared to cell growth in unmodified NAGT medium.

[0054] Thus, in some cases, such NAGT medium can be specific for A. muciniphila strains (DSM 33213) and can include any one or more of the following components: soytone, pea peptone, yeast extract, sodium bicarbonate (NaHCO3), dibasic potassium phosphate (K2HPO4), sodium chloride (NaCl), magnesium sulfate (e.g., MgSO4 x 7H2O), calcium chloride (CaCl2), glucose, N-acetylglucosamine, L-threonine, and / or L-cysteine. In such cases, a volume of about 5 L of modified NAGT medium for growing and culturing A. muciniphila (DSM 33213) cells can include about 75 g to about 100 g of SOLABIA pea peptone, about 75 g to about 85 g of Difco™ Select Soytone (Select Soytone), about 10 g to about 15 g Bacto™ yeast extract, about 2 g to about 8 g sodium bicarbonate (NaHCO3), about 10 g to about 15 g dibasic potassium phosphate (K2HPO4), about 0.5 g to about 5 g sodium chloride (NaCl), about 0.5 g to about 5 g magnesium sulfate heptahydrate (MgSO4 x 7H2O), about 0.5 g to about 5 g calcium chloride (CaCl2), about 20 g to about 25 g glucose (dextrose), about 25 g to about 30 g N-acetylglucosamine, about 15 g to about 25 g L-threonine and / or about 2 g to about 8 g L-cysteine.In one example, a volume of about 5 L of modified NAGT medium for growing and culturing A. muciniphila (DSM 33213) cells may contain about 82.5 g SOLABIA pea peptone, 82.5 g Difco™ Select Soytone, about 12.5 g Bacto™ yeast extract, about 5 g sodium bicarbonate (NaHCO3), about 12.5 g dibasic potassium phosphate (K2HPO4), about 1.5 g sodium chloride (NaCl), about 0.5 g magnesium sulfate heptahydrate (MgSO4 x 7H2O), about 0.5 g calcium chloride (CaCl2), about 22.6 g glucose (dextrose), about 27.7 g N-acetylglucosamine, about 20 g L-threonine and / or about 5 g L-cysteine.

[0055] The pH of such NAGT medium may be adjusted, for example, to about 6.5±0.1, for example, using 5M hydrochloride solution. The pH of such NAGT medium may also be adjusted to about 7. A. muciniphila (DSM 33213) bacterial cells may be added into a prepared vial containing such NAGT growth medium. After a period of incubation that may be specific for the A. muciniphila (DSM 33213) strain, the absorbance of the cell culture at 600 nm may be measured and recorded to obtain an absorbance value of about 0.5 to about 1.2, preferably about 0.7 to 1.1. The contents of the culture flask may then be centrifuged, the supernatant removed, and the remaining cell pellet resuspended in sterile PBS containing an antioxidant and a cryoprotectant, for example 20% v / v glycerol. Approximately 5×10 per unit dose may be added. 8 ~about 10 10The A. muciniphila (DSM 33213) cell suspension can be dispensed into cryovials to obtain a final A. muciniphila (DSM 33213) cell concentration of 1000 A. muciniphila (DSM 33213) viable cells. Such a unit dose may have a volume of about 1 mL. In such a case, the unit dose may be about 5 x 10 8 The present invention may contain viable cells of A. muciniphila (DSM 33213).

[0056] Further provided herein is a method for producing a batch of F. prausnitzii (DSM 33185) cells that can be used in the bacterial symbionts of the pharmaceutical compositions described herein. Such a method can include preparing a complete vitamin mix solution (e.g., YFAP vitamin mix) and F. prausnitzii (DSM 33185) cell culture medium. The YFAP vitamin mix can be specific for the F. prausnitzii (DSM 33185) strain and can include any one or more of biotin, cobalamin, p-aminobenzoic acid, folic acid, pyridoxamine, thiamine and / or riboflavin. In such a case, a 1 L volume of YFAP Vitamin Mix may contain about 10 mg biotin, about 10 mg cobalamin, about 30 mg p-aminobenzoic acid, about 50 mg folic acid, about 150 mg pyridoxamine, about 50 mg thiamine, and about 50 mg riboflavin. All media components can be dissolved to obtain a clear solution free of solids and precipitates. For use in F. prausnitzii (DSM 33185) culture, the YFAP Vitamin Mix medium can be filtered and sterilized as described below.

[0057] Such F. prausnitzii (DSM 33185) medium may be prepared to contain any one or more of BBL™ Phytone Peptone, SOLABIA Pea Peptone, Difco™ Select Soytone, Bacto™ Yeast Extract, sodium bicarbonate (NaHCO3), dibasic potassium phosphate (K2HPO4), sodium chloride (NaCl), magnesium sulfate heptahydrate (MgSO4 x 7H2O), sodium acetate (NaOAc), glucose (dextrose), sodium propionate, L-cysteine, and / or YFAP vitamin mix solution (e.g., as prepared as described above). In such a case, a volume of about 5 L of F. prausnitzii (DSM 33185) medium may be prepared by mixing about 75 g to 100 g of SOLABIA Pea Peptone. peptone, about 45 g to about 55 g of BBL™ Phytone Peptone, 45 g to about 55 g of Difco™ Select Soytone, about 20 g to about 30 g of Bacto™ Yeast Extract, about 2 g to about 8 g of sodium bicarbonate (NaHCO3), about 10 g to about 15 g of dibasic potassium phosphate (K2HPO4), about 2 g to about 8 g of sodium chloride, about 0.5 g to about 2 g of magnesium sulfate heptahydrate (MgSO4 x 7H2O), about 20 g to about 30 g of sodium acetate (NaOAc), about 40 g to about 60 g of glucose (dextrose), about 2 g to about 8 g of sodium propionate, about 2 g to about 8 g of L-cysteine, and about 0.5 to about 3 mL of YFAP vitamin mix solution (e.g., prepared as described above). Thus, in one example, a volume of about 5 L of F. prausnitzii (DSM 33185) medium can contain about 100 g SOLABIA pea peptone, 50 g BBL™ Phytone peptone, about 50 g Difco™ Select Soytone, about 25 g Bacto™ yeast extract, about 5 g sodium bicarbonate (NaHCO3), about 12.5 g dibasic potassium phosphate (K2HPO4), about 5 g sodium chloride, about 1 g magnesium sulfate heptahydrate (MgSO4 x 7H2O), about 25 g sodium acetate (NaOAc), about 50 g glucose (dextrose), about 5 g sodium propionate, about 5 g L-cysteine, and about 1 mL of YFAP vitamin mix solution (e.g., prepared as described above).

[0058] F. prausnitzii (DSM 33185) medium YFAP-NU can be prepared to contain any one or more of pea peptone, NuCel® 783 yeast extract, sodium bicarbonate (NaHCO3), dibasic potassium phosphate (K2HPO4), sodium chloride (NaCl), magnesium sulfate heptahydrate (MgSO4 x 7H2O), sodium acetate (NaOAc), glucose (dextrose), L-cysteine ​​and / or cobalamin. In such a case, a volume of about 5 L of F. prausnitzii (DSM 33185) medium may contain about 75 g to 100 g of pea peptone, about 50 g of NuCel® 783 yeast extract, 5 g of sodium bicarbonate (NaHCO3), about 12.5 g of dibasic potassium phosphate (K2HPO4), about 5 g of sodium chloride (NaCl), about 1 g of magnesium sulfate heptahydrate (MgSO4 x 7H2O), about 25 g of sodium acetate (NaOAc), about 50 g of glucose (dextrose), about 5 g of L-cysteine, and about 5 g of cobalamin.

[0059] The pH of such cell culture medium may be adjusted to about 6.5±0.1, for example, using glacial acetic acid. Such pH may vary from about 6.2 to about 6.8, depending on the bacterial strain used. In some cases, the pH of the cell culture medium may not be adjusted. Such pH may vary from about 4.5 to about 7.5. In some embodiments, the pH of such medium may be about 5, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7, 7.1, 7.2, 7.3, 7.4, or 7.5. After reduction to anaerobic conditions, a starter culture of F. prausnitzii (DSM 33185) may be prepared by adding a specific amount of stock F. prausnitzii (DSM 33185) solution, for example about 500 μL of cell bank stock solution, to a starter culture tube containing reduced medium, followed by incubation at 37° C. for about 12-16 hours. After growth of the starter culture (for example, after about another 12-24 hours of incubation), the absorbance of the cell culture at 600 nm is measured, measured in triplicate, to ensure that the absorbance is within a specific range. Such absorbance range may be about 1.2 to about 2.0, preferably about 1.4 to about 1.8. The culture flask may then be centrifuged, the supernatant removed, and the remaining cell pellet resuspended in sterile PBS to obtain a homogenous solution. In some cases, the F. prausnitzii (DSM 33185) cell suspension was dispensed into cryovials (e.g., 2 mL cryovials) to achieve a final F. prausnitzii (DSM 33185) cell concentration of approximately 5 × 10 per unit dose. 8 ~about 10 10 Such a unit dose may be about 5×10 viable cells of F. prausnitzii (DSM 33185). Such a unit dose may have a volume of about 1 mL. In such a case, such a unit dose may be about 5×10 8The present invention may include F. prausnitzii (DSM 33185) cells.

[0060] The present disclosure also provides methods that include constructing one or more cell batches of a strain to be included in the bacterial symbiont used in the pharmaceutical composition. For example, in some cases, such methods include constructing a cell population of one or more of the bacterial strains in Table 1. In such cases, cell batches produced for any one or more of the strains Lactobacillus crispatus (DSM 33187), A. muciniphila (DSM 33213), and F. prausnitzii (DSM 33185) can be combined to form the bacterial symbiont used in the pharmaceutical composition.

[0061] Such a method may include determining the amount of metabolically active cells in each cell population of a bacterial strain. If the bacterial symbiont of the pharmaceutical composition comprises or consists of the three bacterial strains Lactobacillus crispatus (DSM 33187), A. muciniphila (DSM 33213) and F. prausnitzii (DSM 33185), the number of metabolically active bacterial cells in each of the prepared cell batches may be determined. Such measurements may be performed using any suitable method, for example, the methods described herein. Using information obtained from such measurements, it is possible to determine the amount of unit doses that can be prepared from a given batch of bacterial strains (e.g., L. crispatus (DSM 33187), A. muciniphila (DSM 33213) and / or F. prausnitzii (DSM 33185)). For example, the amount of unit doses that can be prepared from a batch of L. crispatus (DSM 33187) can be determined as follows: Number of potential doses from a L. crispatus (DSM 33187) batch = ((L. crispatus (DSM 33187) mean potency (CFU / mL) × (L. crispatus (DSM 33187) batch volume (mL))) / (4 × 10 8 CFU / dose).

[0062] Thus, in some embodiments, the bacterial symbionts of the pharmaceutical compositions herein are about 5×10 per bacterial species or strain. 8CFU. Once the number of potential unit doses that can be produced from each strain has been calculated, each vial containing cells of each strain can be removed from the freezer and pre-reconstituted in an antechamber before proceeding. After reconstitution and thawing, the calculated amount of cell suspension volume of each strain can be transferred to a 1 L glass bottle and the volume increased using a buffer such as PBS to give a calculated cell concentration per milliliter. In some cases, such a calculated concentration is approximately 5×10 8 CFU / bacterial species / mL pharmaceutical composition. The resulting homogenous suspension can be aliquoted into unit doses using cryovials and stored at -80°C until further use, such as administration to a subject.

[0063] The methods for producing the bacterial symbionts provided herein may further include performing quality control to ensure that the cells of the bacterial strain in each composition are viable and correspond to the correct strain. In such quality control methods, various parameters, test methods and specifications may be evaluated for each batch of strains. Such evaluation may be performed prior to administration of the pharmaceutical composition to a subject. Exemplary quality control parameters may include (i) the concentration of the bacterial strain, and (ii) morphological characteristics by visual inspection of the colony growth. For example, the morphological characteristics of F. prausnitzii (DSM 33185) cell colonies may include circular, full edge, flat, small to medium size, and cream to tan color. Morphological characteristics of A. muciniphila (DSM 33213) cell colonies may include: circular, entire edge, raised, dot-like size, opaque or translucent for A. muciniphila (DSM 33213) cells, and L. crispatus (DSM 33187) cell colonies may include: circular, entire edge, raised, small to medium, white to cream color.

[0064] The present disclosure provides pharmaceutical compositions that can be designed and manufactured to allow for storage and / or transport of the pharmaceutical composition. In some cases, the pharmaceutical compositions herein that include a bacterial symbiont can be designed such that the viability of the bacterial cells in the pharmaceutical composition is not or only minimally affected by storage and / or transport. In such cases, at least about 80%, 85%, 90%, 95%, 97% or 99% viability of the bacterial cells in the pharmaceutical composition is maintained during storage and / or transport.

[0065] In some cases, the pharmaceutical compositions herein include a cryoprotectant to allow storage at low temperatures of about -70°C or -80°C to maintain viability of the bacterial cells. In such cases, the pharmaceutical compositions may include about 20% v / v glycerol as a cryoprotectant. The pharmaceutical compositions herein may further include an antioxidant that can maintain an anaerobic environment in the storage or shipping vial and protect the bacterial cells from reactive oxygen species.

[0066] In one example, in the pharmaceutical compositions herein, live vegetative bacteria may be stored frozen in phosphate buffered saline (PBS) containing 20% ​​v / v glycerol and 0.1% w / w cysteine ​​to maintain their viability. In such cases, the live bacteria may belong to any one or more of the strains shown in Table 1.

[0079] EXAMPLES These examples are provided for illustrative purposes only and are not intended to limit the scope of the claims contained in this application.

[0080] Example 1: Growth, isolation and characterization of bacterial strains The present specification provides methods for the growth, isolation and characterization of bacterial strains isolated from human samples. Such strains can be used as part of the bacterial symbionts described herein.

[0081] 1. Bacterial Growth In general, the procedures for growing bacteria described herein can be used to culture pure anaerobic and facultative anaerobic bacterial strains. The bacterial strains in this example were obtained from human fecal samples and grown in selective media. Upon subculture, colonies were transferred to liquid media and then prepared for PCR and sequencing. Colonies were also stored as glycerol stocks.

[0082] First, human fecal samples were collected in anaerobic transport medium (Anaerobic Systems As-915) or in fecal collection vials sealed in plastic bags containing an anaerobic atmosphere generating system (e.g., AnaeroPouch Thermo Fisher R686001). All samples were immediately transferred into the anaerobic chamber to minimize transit time and potential oxygen exposure, ensuring viability of the anaerobic strains.

[0083] Serial dilution tubes were prepared by dispensing 0.9 mL of PBS+Cys (1x PBS + 0.1% w / w L-cysteine) into 13 tubes (having a volume of 1.5 mL). Using a disposable spatula or loop, 20-30 mg of sample was transferred into the first 1.5 mL tube containing 0.9 mL of PBS+Cys. The resulting mixture was vortexed for approximately 30 seconds, and 0.1 mL of the resulting homogenous solution was transferred into the second 1.5 mL tube containing 0.9 mL of PBS+Cys. All 13 tubes then contained serial dilutions of the sample (e.g., 1-10 in vials 1-13). -12 This process was repeated until dilution.

[0084] Use a disposable hockey stick spreader to -5 ~10 -12 Approximately 0.1 mL from the sample tubes containing the dilutions (vials 6–13) was added to separate agar plates containing selective agar growth medium. The agar plates were then sealed with parafilm to prevent evaporation and placed in an incubator at 37°C for 72 hours. Colonies matching specific morphological characteristics of colonies [e.g., L. crispatus (DSM 33187), A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185), etc.] were identified and placed on new pre-reduced agar plates for isolation. The agar plates were sealed with parafilm and placed in an anaerobic incubator at 37°C for an additional 72 hours.

[0085] Specific isolated colonies were picked from the culture plate and transferred into liquid medium by resuspending the colony in 1 mL of pre-reduced liquid broth. Positive and negative controls of the selected organisms were inoculated in parallel to compare growth and monitor contamination, respectively. All liquid colony samples were then incubated at 37°C for 72 hours.

[0086] Positive and negative controls were used to identify the positive matched broth cultures. Glycerol stocks of the positive matched broth cultures were prepared by transferring 0.75 mL of broth culture into 2 mL cryotubes containing 0.75 mL of 50% v / v glycerol in PBS. The sealed cryotube samples were then removed from the anaerobic chamber and stored at -80°C. The remaining broth culture samples were used for identification of the isolates using 16S-based PCR as described below.

[0087] 2. 16S-based PCR for Identification of Isolates Broth culture samples were centrifuged to form a cell pellet, and the resulting supernatant was carefully removed to leave the formed cell pellet intact. The cell pellet was then resuspended in 0.5–1 mL of ultrapure water.

[0088] A PCR master mix for a final reaction volume of 50 μL was prepared using the following PCR components (NEB E5000S) and volumes: 10x buffer (5 μL), 10 mM dNTPs (1 μL), 10 μM 27F forward primer (1 μL), 10 μM 1492R reverse primer (1 μL), tag polymerase (0.25 μL) and sterile water (40.25 μL). PCR master mix (48.5 μL) and 1.5 μL of resuspended bacterial cells were placed in a 0.2 mL PCR strip tube and after vortexing, the PCR reaction samples were subjected to the following thermocycler protocol (Table 3). [Table 3]

[0089] Upon completion of the PCR reaction, samples were subjected to Sanger sequencing using GENEWIZ or an equivalent vendor.

[0090] 3. Characterization of isolated bacterial strains Table 4 below shows the short chain fatty acid production, antibiotic resistance and whole genome sequencing analysis of strains (also shown in Table 2) A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185) and L. crispatus (DSM 33187) that may form the bacterial symbionts used in the pharmaceutical compositions in various embodiments of the present disclosure. [Table 4]

[0091] Example 2: Production of Bacterial Composition A Production conditions were adjusted to increase the yield and growth rate of the bacterial strains described herein. In particular, the bacterial strains Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus subtilis (DSM 33186) were produced. For Lactobacillus crispatus (DSM 33187), production conditions were obtained to increase yield and growth rate. Figure 1 herein shows a schematic flow chart summarizing the manufacturing process for producing Composition A using these strains.

[0092] 1. Preparation of medium Animal-free medium was used in the manufacturing process of this example. To obtain the bacterial batch, 5 L of broth medium was first prepared for each of the strains. After complete dissolution of the medium components by vigorous stirring in USP grade water for 15 minutes, the pH of the medium was adjusted with hydrochloric acid. The pH-adjusted medium was then transferred to a biosafety cabinet and filter-sterilized using a 0.2 μm vacuum filter unit (e.g., using 1 liter portions five times). The filter-sterilized growth medium was immediately transferred to an anaerobic chamber containing an atmosphere of N2H2CO2 (90:5:5) and stored with a vented cap for 12-18 hours for reduction before inoculation.

[0093] 2. Inoculation and Culture After 12-18 hours of medium reduction under anaerobic conditions, 10 mL from each 1 L filter flask was transferred to a pre-reduced sterile 15 mL screw-cap tube, labeled "Sterile Control #5". An additional 40 mL of sterile medium was transferred to two separate 50 mL Falcon tubes, labeled "Starting Culture X 2". One 2 mL Master Cell Bank (MCB) cryovial was removed from -70°C storage, the outside of the vial was washed with 70% EtOH, and wiped dry with a lint-free wipe. The MCB aliquot was then transferred into the anaerobic chamber and placed in a tube rack to thaw for 5-10 minutes. Once completely thawed, a 500 μL aliquot of the thawed 1 mL MCB was transferred to each of the two 40 mL starting cultures using a sterile 1 mL filtered pipette tip. The caps of the inoculated starter culture tubes and the sterile control were tightly tightened, and the control and starter cultures were incubated under anaerobic conditions at approximately 37°C for 12-16 hours.

[0094] After 12-16 hours, the starter cultures and sterile controls were removed from the incubator and visually inspected for growth (e.g., turbidity). The sterile controls were also confirmed for lack of visible growth or turbidity before proceeding. Once confirmed, 10 mL of the starter culture was carefully transferred using a sterile 10 mL serological pipette tip to each of five pre-warmed 1 L flasks containing pre-reduced, filter-sterilized medium. The cultures were then incubated at 37°C under anaerobic conditions for 12-16 hours. After incubation, the turbidity of the cultures was quantified using absorbance spectroscopy (Epoch 2 Plate Reader, Biotek) to confirm growth within the set parameters. The absorbance of the cultures was measured at a target OD 600 Once it was confirmed that the cell viability was within the range, the cells were harvested by centrifugation.

[0095] 3. Harvesting. 12-18 hours prior to cell harvest, place five sterile 1 L centrifuge bottles (Beckman Coulter) with screw cap seals into the anaerobic chamber to reduce the bottles before use. Grow the cultures and allow them to grow until the cultures reach the target OD 600 After ensuring that the pH was within range, the culture was transferred into a sterile 1 L centrifuge bottle. The cap of the centrifuge bottle was tightly sealed to prevent gas exchange, and the bottle was transferred to a pre-cooled bed centrifuge containing 6 x 1 L rotors. The cells were pelleted at 8,000 x g for 30 minutes at 4 °C. After centrifugation, the cell pellet was placed back into the anaerobic chamber, and the clarified culture supernatant was completely removed from the pellet using a sterile serological pipette. The cell pellet was then combined by resuspension at 40x concentration in pre-reduced cryoprotectant solution. The concentrated cell suspension was then dispensed into 1 mL aliquots in pre-reduced, pre-labeled 2 mL screw-cap cryovials and immediately transferred to a pre-labeled -70 °C storage box. After 3 days of manufacturing and initial storage at -70 °C, the drug substance strain was subjected to specification testing.

[0096] The manufacturing procedures for A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185) and L. crispatus (DSM 33187) cells used in the pharmaceutical composition are described below.

[0097] A. Generation of A. muciniphila (DSM 33213) Cells for Use in Pharmaceutical Compositions For the preparation of the medium, 4.9 L of water (for injection) was added to a 5 L beaker, followed by Difco™ Select Soytone (82.5±0.82 g), Bacto™ Yeast Extract (12.5±0.12 g), sodium bicarbonate (NaHCO3) (5±0.05 g), dipotassium hydrogen phosphate (K2HPO4) (12.5±0.12 g), sodium chloride (NaCl) (1. 5±0.015 g), magnesium sulfate heptahydrate (MgSO4×7H2O) (0.5±0.05 g), calcium chloride (CaCl2) (0.5±0.05 g), glucose (dextrose) (22.6±0.22 g), N-acetylglucosamine (27.7±0.27 g), L-threonine (20±0.2 g) and L-cysteine ​​(5±0.05 g) were added under mixing. The mixture was stirred until all ingredients were completely dissolved, clear and free of solids and precipitates.

[0098] The pH of the NAGT medium was adjusted to 6.5 ± 0.1. The medium was then vacuum filtered and divided into five 1 L batches. After the medium was completely reduced (approximately 12-16 hours later), a starting culture of A. muciniphila (DSM 33213) bacterial cells was prepared using a volume of 45 mL of medium. A. muciniphila (DSM 33213) bacterial cells (approximately 500 μL of stock solution) were taken from the cell bank and added into the prepared vial containing the growth medium. The cell suspension was then warmed and incubated in a 37 °C incubator unit for 24-60 hours to obtain a cloudy / turbid suspension. The absorbance at 600 nm was then measured and recorded in triplicate experiments to obtain a value of approximately 0.7-1.1.

[0099] The culture flasks were then centrifuged at 8000 rpm for 30 min at 4 °C using a JLA8.1000 centrifuge. After removing the supernatant, the remaining cell pellets were resuspended in 25 mL of sterile PBS-GC (40 times the original culture volume) and then combined to obtain a homogenous solution. The A. muciniphila (DSM 33213) cell suspension was dispensed into 2 mL cryovials to obtain 1 × 10 cells per vial. 9 A final A. muciniphila (DSM 33213) cell concentration of over 1000 μg / ml of viable A. muciniphila (DSM 33213) cells was obtained and stored at -80°C until further use.

[0100] B. Generation of F. prausnitzii (DSM 33185) Cells Used in Pharmaceutical Compositions For preparation of YFAP Vitamin Mix Solution, a 1 L bottle was filled with water (for injection) and then biotin (10 ± 1 mg), cobalamin (10 ± 1 mg), p-aminobenzoic acid (30 ± 1 mg), folic acid (50 ± 1 mg), pyridoxamine (150 ± 1 mg), thiamine (50 ± 1 mg) and riboflavin (50 ± 1 mg) were added under mixing. The mixture was stirred until all components were completely dissolved, clear and free of solids and precipitates. The YFAP Vitamin Mix medium was then filtered and sterilized.

[0101] To prepare the medium, add 4.9 L of water (for injection) to a 5 L beaker, followed by BBL™ Phytone Peptone (50 ± 0.5 g), Difco™ Select Soytone (50 ± 0.5 g), Bacto™ Yeast Extract (25 ± 0.25 g), sodium bicarbonate (NaHCO3) (5 ± 0.05 g), dibasic potassium phosphate (K2HPO4) (12.5 ± 0.12 g), sodium chloride (NaCl) (1 ± 0.05 g), and 100% ethanol. NaCl (5±0.05 g), magnesium sulfate heptahydrate (MgSO4×7H2O) (1±0.01 g), sodium acetate (NaOAc) (25±0.25 g), glucose (dextrose) (50±0.25 g), sodium propionate (5±0.05 g), L-cysteine ​​(5±0.05 g), and YFAP vitamin mix solution (1 mL; prepared as above) were added under mixing. The mixture was stirred until all components were completely dissolved, clear, and free of solids and precipitates.

[0102] The pH of the YFAP medium was then adjusted to 6.5 using 5M hydrochloride solution. The medium was then filtered and left in the dark for approximately 12-18 hours for complete reduction to anaerobic conditions. After a volume of medium was transferred to the starting culture tube, approximately 500 μL of F. prausnitzii (DSM 33185) stock solution was transferred into the starting culture tube and incubated at 37 °C for approximately 12-16 hours. The starting culture tube was assessed for turbidity, divided into five aliquots, and added to pre-warmed 1 L flasks containing sterile medium and then incubated at 37 °C for 12-16 hours.

[0103] After incubation, the absorbance at 600 nm was measured and repeated in three duplicate experiments to ensure that the absorbance was within the range of 1.4-1.8 absorbance. The culture flasks were centrifuged at 8000 rpm and 4 °C for 30 min using a JLA8.1000 centrifuge. After removing the supernatant, the remaining cell pellet was resuspended in 25 mL of sterile PBS-GC (40 times the original culture volume) and then combined to obtain a homogenous solution. The F. prausnitzii (DSM 33185) cell suspension was dispensed into 2 mL cryovials to obtain 1 × 10 cells per vial. 9 A final F. prausnitzii (DSM 33185) cell concentration of over 1000 μg / ml of viable F. prausnitzii (DSM 33185) cells was obtained and stored at -80°C until further use.

[0104] C. Preparation of Lactobacillus crispatus (DSM 33187) Cells Used in Pharmaceutical Compositions For preparation of vMRS medium, 4.9 L of water (for injection) was added to a 5 L beaker, followed by 273 g of vMRS powder and dipotassium phosphate (K2HPO4) (12.5±0.1 g) under mixing. The mixture was stirred until all components were completely dissolved, clear, and free of solids and precipitates.

[0105] The pH of the vMRS medium was then adjusted to 6.5 with NH4OH or acetic acid. The medium was then filtered using a 0.2 μm vacuum filter unit and left in the dark for approximately 12-18 hours for complete reduction to anaerobic conditions. After a volume (e.g., 45 mL) of medium was transferred to a starting culture tube, approximately 500 μL of L. crispatus (DSM 33187) stock solution was transferred into the starting culture tube and incubated at 37°C for approximately 16-20 hours. The starting culture tube was assessed for turbidity, divided into five aliquots, and added to pre-warmed 1 L flasks containing sterilized medium and then incubated at 37°C for approximately 16-20 hours.

[0106] Incubate After incubation, the absorbance at 600 nm was measured and repeated in three duplicate experiments to ensure that the absorbance was within the range of 1.0-1.4 absorbance. The culture flasks were centrifuged at 8000 rpm and 4 °C for 20 min using a JLA8.1000 centrifuge. After removing the supernatant, the remaining cell pellet was resuspended in 25 mL of sterile PBS-GC (40 times the original culture volume) and then combined to obtain a homogenous solution. The Lactobacillus crispatus (DSM 33187) cell suspension was dispensed into 1 mL cryovials to obtain 1 × 10 cells per vial. 9 A final L. crispatus (DSM 33187) cell concentration of over 1000 L. crispatus (DSM 33187) viable cells was obtained and stored at -80°C until further use.

[0107] D. Construction of Composition A To prepare three bacterial strains that can be used as bacterial symbionts in the pharmaceutical compositions described herein, A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185) and L. crispatus (DSM 33187), the number of metabolically active bacterial cells in the final cell suspension stored at -80°C in cryovials was determined for each strain. The maximum number of possible oral doses that can be obtained from a batch of three strains can be calculated as follows (Table 5): [Table 5]

[0108] A complete list of ingredients for Composition A is provided in Table 6. [Table 6]

[0109] Once the stock vials containing the strains listed in Table 6 have thawed (approximately 15-20 min after removal from the freezer), transfer the calculated amount of cell suspension volume for each strain into a 1 L glass bottle and mix to obtain the calculated concentration of cells per mL (e.g., 5 x 10 in this example). 8 The volume was increased using PBS-GC to reach a CFU / bacterial species / mL. The resulting homogenous suspension of mixed species drugs was dispensed into 1 mL volumes in cryovials and stored at -80°C until further use.

[0110] E. Quality Control of Composition A The following parameters, test methods and specifications, as set forth in Table 7, were evaluated for each batch of Composition A for quality control purposes. [Table 7]

[0111] Testing for objectionable microorganisms is performed using standard protocols in accordance with USP <62> Briefly, samples were first enriched by inoculation into casein digest broth soybean (SCDA) or other suitable neutralizing medium and then streaked onto selective agar for determination of the presence of identified / undesirable microorganisms.

[0112] The total number of microorganisms present in a sample was counted using standard protocols according to USP <61> Such microbial enumeration was performed using either membrane filtration, pour plating or spread plate techniques.

[0113] Example 3: Optimization of the growth medium In this example, we demonstrate the optimization of the growth medium composition for culturing the bacterial strains described herein, including, in particular, Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187), which are used in bacterial symbiosis.

[0114] 1. Akkermansia muciniphila (DSM 33213) The growth of A. muciniphila (DSM 33213) cells in N-acetylglucosamine threonine (NAGT) medium was evaluated at various pH values, along with the simultaneous removal of one medium component to evaluate the effect of such medium component on the growth of A. muciniphila (DSM 33213) cells. Typical NAGT medium had a pH of 6.5 and contained 11.9 mM sodium bicarbonate. When A. muciniphila (DSM 33213) cells were grown in modified NAGT medium containing 47.6 mM sodium bicarbonate and a pH of 7.5, there was an approximately 40% increase in growth (OD 600 When measured by , an increase in biomass was observed (curve 2, Figure 2). An increase in biomass was also confirmed by using the plating method. Removal of glucose (curve 3, Figure 2), magnesium sulfate (curve 4, Figure 2) or calcium chloride (curve 5, Figure 2) from the modified NAGT medium showed little or no effect on the growth of A. muciniphila (DSM 33213) cells.

[0115] Figure 3 shows that soytone and N-acetylglucosamine (NAG) appear to be required for the growth of A. muciniphila (DSM 33213) cells, as growth curves 2 and 3, respectively, show no bacterial growth in media lacking soytone or NAG. Growth curve 1 shows robust growth of A. muciniphila (DSM 33213) cells in NAGT medium, which contains both soytone and NAG.

[0116] 2. Faecalibacterium prausnitzii (DSM 33185) The effect of specific components in YFAP medium on the growth of Faecalibacterium prausnitzii (DSM 33185) cells was assessed by removing one medium component at a time. For example, Figure 4 shows that yeast extract [e.g., curve 3 shows the growth of FP (DSM 33185) in medium lacking yeast extract] and cysteine ​​[e.g., curve 4 shows the growth of FP (DSM 33185) in medium lacking yeast extract] appear to be necessary for the growth of F. prausnitzii (DSM 33185) cells when compared to the growth of F. prausnitzii (DSM 33185) cells in complete medium (curve 1). The absence of sodium acetate (curve 5) does not appear to impede the growth of F. prausnitzii (DSM 33185) cells, whereas the absence of soytone (curve 2) appears to result in cell death in late logarithmic and stationary phases.

[0117] The effect of the type of vitamin supplement on the growth of F. prausnitzii (DSM 33185) cells was also investigated. For example, Figure 5 shows that the addition of vitamins increased the yield of F. prausnitzii (DSM 33185) cells subcultured three times in vitamin-free YFAP medium. The final OD of F. prausnitzii (DSM 33185) grown in vitamin-containing YFAP (YFAP + vitamins) was 1.0 μg / mL. 600was approximately 10% higher than that grown in YFAP medium lacking thiamine (thiamine-free YFAP), pyroxamine (pyroxamine-free YFAP), folate (folate-free YFAP), cobalamin (cobalamin-free YFAP), PABA (PABA-free YFAP), riboflavin (riboflavin-free YFAP), vitamins (vitamin-free YFAP), or biotin (biotin-free YFAP). YFAP+vitamin medium includes YFAP medium supplemented with a complete vitamin mix solution (e.g., YFAP vitamin mix). The YFAP vitamins include about 10 mg / L biotin, about 10 mg / L cobalamin, about 30 mg / L p-aminobenzoic acid, about 50 mg / L folic acid, about 150 mg / L pyridoxamine, about 50 mg / L thiamine, and about 50 mg / L riboflavin.

[0118] In another example, Figure 6 shows that cobalamin was a notable factor for optimal growth of F. prausnitzii (DSM 33185) cells subcultured once in vitamin-free YFAP medium. The final OD of F. prausnitzii (DSM 33185) grown in YFAP lacking cobalamin (YFAP no cobalamin) was 1.2 mg / ml. 600 was approximately 30% lower than that grown in YFAP medium lacking thiamine (thiamine-free YFAP), pyroxamine (pyroxamine-free YFAP), folate (folate-free YFAP), PABA (PABA-free YFAP), riboflavin (riboflavin-free YFAP), biotin (biotin-free YFAP), or with the addition of vitamins (YFAP+vitamins). The growth disadvantage in YFAP lacking cobalamin was similar to that in YFAP lacking vitamins (vitamin-free YFAP).

[0119] The pH of the medium was also shown to be a notable factor for the growth of F. prausnitzii (DSM 33185) cells. Figure 7 shows the growth of F. prausnitzii (DSM 33185) cells in the absence of pH control, and Figure 8 shows the growth of F. prausnitzii (DSM 33185) cells in the presence of pH control. When the pH was controlled at 6 with ammonium hydroxide (NH4OH), the redox potential dropped to -460 mV and bacterial growth increased to OD 600 When pH was not controlled, the redox potential was maintained at -400 mV and bacterial growth was at OD 600 = 1.1. Thus, the culture in the absence of pH control produced 50% more bacteria than the culture in the presence of pH control.

[0120] 3. Lactobacillus crispatus (DSM 33187) Lactobacillus crispatus (DSM 33187) is generally available from HiMedia Laboratories. The cells were grown in vMRS broth obtained from Biokar diagnostics (Reference: BK176HA). However, Figure 9 shows that the growth of L. crispatus (DSM 33187) cells increased by approximately 55% when the medium was made with Boullion MRS Vegetal obtained from Biokar diagnostics (Reference: BK176HA) (Curve 2) compared to when HiMedia vMRS broth was used (Curve 1). Without being bound by any theory, it is believed that the observed improvement in cell growth is due to the higher amount of vegetable peptone in Boullion MRS Vegetal (approximately double the amount at 20 g / L) compared to HiMedia vMRS broth.

[0121] Example 4: Large-scale growth of bacteria (20 L) To increase the yield and growth rate of the bacterial strains described herein, production conditions were prepared for growing the bacteria in a culture with a volume of 20 L. In particular, production conditions were obtained to increase the yield and growth rate for the bacterial strains Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187).

[0122] Large-scale propagation of Akkermansia muciniphila (DSM 33213) To prepare NAGT medium for 1 L inoculum culture and 20 L primary culture, weigh out the medium components as follows: pea peptone (16.5 g / L), yeast extract (2.5 g / L), dextrose (45.2 g / L), dibasic potassium phosphate (K2HPO4) (2.5 g / L), sodium chloride (NaCl) (0.3 g / L), magnesium sulfate heptahydrate (MgSO4 × 7H2O) (0.1 g / L), sodium bicarbonate (NaHCO3) (1 g / L), calcium chloride (0.1 g / L), N-acetylglucosamine (5.54 g / L), L-threonine (4 g / L), L-cysteine ​​(1 g / L). The mixture was stirred until all ingredients were completely dissolved and the solution was clear and free of solids and precipitates.

[0123] The pH of NAGT medium was adjusted to 6.5±0.1 with NH4OH and acetic acid. The medium was then sterilized by autoclaving at 121° C. for 20 minutes. The glucose and N-acetylglucosamine feeds were filter sterilized separately. The medium components were then mixed together.

[0124] The inoculated flasks containing NAGT were transferred to an anaerobic chamber and degassed with N2H2CO2 (90:5:5) by incubating for 48 h under anaerobic atmosphere.

As shown in Figure 14, a feed of 5250 g glucose was added at 10 hours and the bacterial culture was maintained in exponential growth from 10 hours to 12 hours and transitioned to stationary growth from 12 hours onwards. The culture was stopped a) when a phase of growth deceleration was observed or b) when the culture was grown for 24 hours.

[0143] Large-scale growth of Faecalibacterium prausnitzii (DSM 33185) To prepare YFAP medium for 1 L inoculum culture and 150 L primary culture, the medium components are weighed out as follows: pea peptone (20 g / L), yeast extract (5 g / L), dextrose (10 g / L), dibasic potassium hydrogen phosphate (K2HPO4) (2.5 g / L), sodium chloride (NaCl) (1 g / L), magnesium sulfate heptahydrate (MgSO4 x 7H2O) (0.2 g / L), sodium bicarbonate (NaHCO3) (1 g / L), sodium acetate (NaOAc) (5 g / L), L-cysteine ​​(1 g / L). YFAP vitamin mix solution was prepared as described in Example 3.

[0144] The pH of the YFAP medium was adjusted to 6.5±0.1 with NaOH and acetic acid. The medium was then sterilized by autoclaving at 121° C. for 20 minutes. The glucose and YFAP vitamin mix solutions were filter sterilized (0.2 μm filter). The medium components were then mixed together.

[0145] The inoculated flasks containing YFAP were transferred to an anaerobic chamber and degassed with N2H2CO2 by incubating for at least 16 h under anaerobic atmosphere. Inoculum cultures were inoculated from the RCB or MCB [0.4% for F. prausnitzii (DSM 33185)] and grown at 37 °C under anaerobic atmosphere without stirring. Culture glucose consumption and optical density were monitored every 2 h. Cultures were stopped when a) a phase of deceleration was observed or b) the cultures were grown for 24 h.

[0146] 150 L of medium was degassed by gassing using N2H2CO2 (90:5:5). Degassing was performed at 6.5 L / min until the redox values ​​dropped and stabilized. As shown in Figure 15, the primary culture was inoculated at 0.4% (e.g., about 600 mL of inoculum culture) and maintained exponential growth from 11 to 16 hours, with culture glucose consumption and optical density monitored every 2 hours.

[0147] Example 6: Freeze-drying of bacteria To prepare a cryoprotectant solution for bacteria grown in large-scale growth conditions, sucrose (80 g / L), trehalose (13.3 g / L), sodium glutamate (5.3 g / L), L-cysteine ​​(1.3 g / L) were mixed with water, filter sterilized (0.2 μm filter) and degassed by gas injection using N2H2CO2 (90:5:5) gas. Redox conditions were monitored with a standard calibrated redox probe. Degassing was continued until the redox values ​​dropped and stabilized indicating complete anaerobic conditions (approximately 60 min). The fully reduced cryoprotectant mixture was sealed to prevent air ingress until use. All Sharples centrifuge and mixing tank components were sterilized in place by autoclaving at 121° C. for 20 min.

[0148] Bacteria were grown for 31 hours and harvested from 20 L or 150 L cultures using a refrigerated Sharples centrifuge set at 10°C. The bacteria in the cylinder were immediately transferred to a sterile blender bag and the biomass was weighed. Equal weights of anaerobic and pre-reduced cryoprotectant solutions were then added to the blender bag. An anaerobic gas line was inserted into the corner of the blender bag. The bacteria and cryoprotectant mixture was gassed with N2H2CO2 (90:5:5) gas at a flow rate of 6.5 L / min for 5 minutes.

[0149] After injecting anaerobic gas to ensure that the mixture of concentrated bacteria and cryoprotectant was maintained under anaerobic conditions, the blender bag was sealed and placed into a second blender bag, which was then placed into a JumboMix 3500 paddle mixer and blended for 5 minutes at Speed ​​#3 to obtain a homogenous anaerobic mixture.

[0150] After homogenization, the cryoprotectant solution containing the bacteria was pumped into single-use freeze-drying plates. Each plate was weighed. The plates were immediately transferred to a pre-cooled (-40°C) freeze-dryer for freeze-drying using the process listed in Table 8. [Table 8]

[0151] The lyophilization run was terminated once the product temperature was stable for at least 2 hours. The lyophilized product was ground using a grinding setting of 1 mm and stored in vacuum sealed bags at -20°C until use.

[0152] Example 7: Comparison of agar plating and flow cytometry to measure metabolically active cell counts in a sample Two different techniques, regular agar plating and flow cytometry, were compared for their ability to provide a consistent and accurate reading of the number of metabolically active cells (e.g., strain potency) of a strain in a sample such as a cell suspension or a biological sample (e.g., a human fecal sample). The strains evaluated include Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and / or Lactobacillus crispatus (DSM 33187), which may be used in the bacterial symbionts herein.

[0153] For example, the method of agar plating was compared to the use of flow cytometry to determine the number of metabolically active bacterial cells (defined as CFU) of Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and / or Lactobacillus crispatus (DSM 33187) in samples.

[0154] 17A-17C show flow cytometry gating experiments of heat-killed control A. muciniphila (DSM 33213) cells for quantification of metabolically active therapeutic strains in bacterial cell populations (e.g., cell populations that may be administered to human subjects). The A. muciniphila (DSM 33213) cell stock solution used as the exemplary strain was diluted to 10 -4 The cells were diluted to 100 μM and placed in a 95° C. heat block for 20 minutes to confirm cell death before performing the experiment. The cells were stained with 2 μM propidium iodide and 2 μM SYTO9. Gates were applied to all cells counted by forward scatter area (FSC-A) and side scatter area (SSC-A) (FIG. 17A) to select for cell size and granularity, respectively. The cells were then linearly gated based on forward scatter high (FSC-H) and forward scatter area (FSC-A) to identify single cells (FIG. 17B). The single cells were then used to set gates for dead cells (PIhighSYTO9low) and live cells (PI-SYTO9high), which indicated the percentage of live and dead cells in the 50 μl solution (FIG. 17C). Figure 17A shows flow cytometry results obtained when a gate was applied to all cells counted by forward scatter area (FSC-A) and side scatter area (SSC-A) to select for cell size and granularity, respectively. Figure 17B shows flow cytometry results obtained when cells were linearly gated based on forward scatter height (FSC-H) and forward scatter area (FSC-A) to identify single cells. Figure 17C shows flow cytometry results obtained when a single cell was used to set gates for dead (PIhighSYTO9low) and live (PI-SYTO9high) cells, showing the percentage of live and dead cells in 50 μl of cell suspension. The data demonstrates that the flow cytometry method can accurately determine the number of metabolically active / inactive cells, as shown in Figure 17C, which shows metabolically inactive cells (cells were heat inactivated).

[0155] Table 9 below shows the set of calculations used to calculate the total viable cell count at each dilution. To calculate the "Total Counted Cells", the diluted and unstained cells were counted mechanically and multiplied by the dilution factor (Dilution Factor x Cells = Total Counted Cells). The "Standard Deviation" and "Average Total Cells" were derived from the "Total Counted Cells". The "% Live Cells" was calculated by applying the control gates described in Figures 17A-17C to the diluted stained cells. The "% Live Cells" was applied to the "Average Total Cells" to calculate the "Total Live Cells" in A. muciniphila (DSM 33213) MCB glycerol stocks. [Table 9]

[0156] Similar results were obtained for the strains Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187), demonstrating that flow cytometry can be used to accurately measure the number of metabolically active therapeutic strains in a sample. Comparison of the total viable cells measured using the plating method with those measured by flow cytometry indicates that flow cytometry can allow a more accurate measurement of the total viable cell number in a sample (see, for example, Figures 17A-17C).

[0157] FIG. 18 also shows a graph comparing the total viable cell counts determined using the (standard) agar plating method with flow cytometry quantification data of viable cells. The data show that flow cytometry allowed for a significantly more accurate measurement of the total viable cell counts in the samples (e.g., quantified as CFU / mL) compared to the plating method. The left y-axis shows the total viable cell counts measured by flow cytometry. The right y-axis shows the calculated mean CFU / mL values ​​from nutrient agar plating for biological duplicate experiments. A two-tailed Mann-Whitney t-test showed no significant difference between the means of the two quantification methods (p-value 0.0532). These results show the variability of the agar plating technique and the relative consistency of the FACS technique, validating the use of the flow cytometer as a method to quantify bacterial strains in biological samples. Samples that can be tested using this technique include human fecal samples and bacterial strain samples that can be analyzed for quality control purposes.

[0158] Taken together, these results demonstrate that the flow cytometry methods described herein can be used to determine (i) the ratio of metabolically active to metabolically inactive cell numbers in a sample, and (ii) the absolute number of metabolically active bacterial cells in a sample.

[0159] Example 8: Quantification of bacterial cells in fecal DNA using qPCR This example describes the use of quantitative polymerase chain reaction (qPCR) for the quantification of the bacterial strains Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187) in samples. This example describes the quantification of the strains using specific primers, qPCR and fecal DNA (as template).

[0160] 1. Materials Table 10 below shows exemplary strain-specific primer sequences used for strain quantification. [Table 10]

[0161] PacBio sequencing was performed on genomic DNA extracted from L. crispatus (DSM 33187), F. prausnitzii (DSM 33185) and A. muciniphila (DSM 332313). Using these data, a comparative genomic analysis of all bacterial strains was performed to identify unique regions within the genomes of L. crispatus (DSM 33187), F. prausnitzii (DSM 33185) and A. muciniphila (DSM 33213). Following identification of the unique regions, qPCR primer pairs (see Table 10 above) were designed targeting the unique regions present within these strains.

[0162] Additional materials used in this experiment included: (i) A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185), and L. crispatus (DSM 33187) DNA; (ii) human fecal DNA sample control (containing no strains); (iii) DNA extracted from clinical samples; (iv) metal 384 qPCR plate holder; (v) DNA / RNAse free sterile Eppendorf tubes; and (vi) QuantStudio 6 qPCR thermocycler.

[0163] 2. Procedure Clinical sample names and DNA concentrations were calculated electronically and all samples were normalized to 10 ng / μL in a final volume of 100 μL. Each run utilized a 7-point positive control standard curve made using pure bacterial DNA diluted in a human fecal DNA background. These standards (abbreviated as "std") were pre-made and pre-aliquoted for ease of use. For the standard curve, the following serial dilutions of target strain DNA were included in the run (Table 11): [Table 11]

[0164] The following items were used in the strain DNA quantification experiment: [Table 12]

[0165] Calculated volumes of water and DNA solution were added to the appropriate wells. The qPCR plate was sealed, vortexed (5-10 seconds), and centrifuged at 1000 rpm for 2 minutes.

[0166] 3. Preparation of primer stocks and master mix Forward and reverse strain-specific primers were completely thawed and primer stocks were maintained at 100 μM in 1× TE buffer (see, for example, Table 10). To two Eppendorf tubes (one for the forward primer and one for the reverse primer), 360 μL of sterile USP grade WFI was added. Then 40 μL of forward primer solution was added, homogenized, and the same process was repeated for the reverse primer solution. The resulting 10 μM primer solution was combined with SYBR Select Master Mix (2× stock) and sterile water and homogenized.

[0167] Using a qPCR 384-well plate, 20 μL of qPCR master mix was dispensed into wells A-N 1-24 and O 1-14. Using a DNA normalization plate, the master mix was dispensed into all 350 wells, then 5 μL of DNA from all wells in row A was taken and inoculated into odd wells in row A of the reaction plate. 5 μL of DNA was then transferred from all wells in row A and inoculated into even wells in row A of the reaction plate. The last two steps were repeated for all wells until DNA was added to the reaction plate. The standard curve stock DNA plate of the appropriate strains was then transferred to the biosafety cabinet and the standards were then pipetted into the correct wells in row P for each reaction plate setup. After mixing and centrifugation, the samples were placed into the Quantstudio qPCR instrument.

[0168] The following cycling conditions were used, as shown in Table 13 below: [Table 13]

[0169] Table 14 below shows the standard curve control cycle threshold (CT) and primer melting temperature (TM) values. Table 14 further shows, for each of the selected strains F. prausnitzii (DSM 33185), L. crispatus (DSM 33187) and A. muciniphila (DSM 33213), the standard amounts of strain cell DNA (e.g., 1 ng, 0.1 ng, 0.01 ng and 0.001 ng) used to generate a standard curve that can be used to quantify the amount of strain cell DNA (using a human fecal DNA background) and the estimated number of strain cells in human fecal DNA in the presence of the same amount of strain cell DNA (e.g., 1 ng, 0.1 ng, 0.01 ng and 0.001 ng) in water (e.g., in the absence of a fecal DNA background). [Table 14]

[0170] Figures 19A-19C show the limit of detection curves generated by plotting the measured C values ​​against the estimated strain cell numbers shown in Table 14 above for the three selected strains A. muciniphila (DSM 33213), F. prausnitzii (DSM 33185) and L. crispatus (DSM 33187), respectively.

[0171] Example 9: Mouse Model System The present specification describes a method for the treatment of inflammatory diseases, such as allergic diseases, in an in vivo mouse model. We provide a method to assess the capacity of bacterial symbionts including three bacterial strains, Lactobacillus crispatus (DSM 33187), A. muciniphila (DSM 33213) and Faecalibacterium prausnitzii (DSM 33185), for the detection of bacterial infections.

[0172] In an allergic airway inflammation model using young adult mice sensitized intratracheally to airway allergens, oral administration of Composition A as defined in Example 2 significantly inhibited the rise in circulating IgE immunoglobulins. Oral administration of Composition A also significantly reduced the proliferation of inflammatory Th2 cells in the lungs, and simultaneously reduced Th2-related gene expression and lung concentrations of the inflammatory cytokines IL-4 and IL-13. Conversely, Composition A led to a significant proliferation of anti-inflammatory Treg cells in the lungs, which is associated with a reduction in allergic asthma-related molecules and immune responses. Also, a significant reduction in circulating IgE levels and airway eosinophilia was observed, while circulating histamine and airway neutrophils tended to decrease. Without being bound by any theory, based on these studies, the proposed mechanism of alleviation of allergic and asthmatic responses was based on the inhibition of Treg cell proliferation and subsequent Th2-driven production of allergen-specific IgE. The proliferation of Treg cells appeared to be crucial, since administration of Composition A was also associated with inhibition of allergic asthma-related proliferation of effector cells, including eosinophils and neutrophils. In contrast to the monoclonal anti-IgE antibody Xolair® (omalizumab), which neutralized IgE effector antibodies involved in the initiation of allergic reactions, the mechanism of action using Composition A may have occurred upstream of the cascade of allergic sensitization, highlighting the preventative potential of Composition A. Composition A was advantageous in that it prevented the generation of new IgE and inflammatory effector cells associated with allergic reactions, and was therefore expected to have far fewer side effects.

[0173] These results indicate that the bacterial symbiont of Composition A was effective in treating allergic airway inflammation. Moreover, the therapeutic effect of such symbionts may be superior to that of the monoclonal anti-IgE antibody Xolair® (omalizumab), while significantly fewer side effects were observed. Taken together, these results can be used as a basis and rationale for clinical trials in human subjects.

[0174] Example 10: Optimized Ultra-Large Scale Growth and Manufacturing Process for Akkermansia muciniphila (DSM 33213) Drug Substance (3500 L) To increase the yield and growth rate of the bacterial strains described herein, manufacturing conditions and procedures were developed for growing Akkermansia muciniphila (DSM 33213) in 3500 L volume cultures, as generally shown in FIG. 20.

[0175] Media Preparation The components were weighed out: 250 L of sugar feed (Table 15), 3160 L of NAGT medium (Table 16), 1.25 L of glacial acetic acid and the cryoprotectant mixture (Table 17). [Table 15] [Table 16] [Table 17]

[0176] Sugar Fractions and Feed Preparation and Decontamination Cleaning in place (CIP) of the 300 L vessel and mix tank was completed. 120 L of hot softened water was added to the sterile mix tank using a 0.22 μm filter. One third of the sugar feed ingredients (by weight) was added to the mix tank and stirred at 150 rpm for 10 minutes until they were completely dissolved. An additional two thirds of the sugar feed ingredients and 120 L of hot softened water were then added to the mix tank and allowed to completely dissolve. The sugar feed was filter sterilized using a 0.2 μm filter and stored in a sterile 300 L vessel.

[0177] Preparation and decontamination of 3500 L medium To prepare NAGT medium, a 3,500 L stirred fermenter was sterilized by CIP and fitted with calibrated pH and redox sensing probes. A total of 400 L of 0.22 μm filtered water was added to the pre-sterilized mixing tank and combined with the NAGT medium components. The mixture was homogenized at 150 rpm for 10 minutes. The concentrated medium was transferred to a 3500 L bioreactor and 3070 L of 0.22 μm filtered soft water was added to the fermenter. The pH of the medium was adjusted to pH=6.5. The medium was sterilized in place at 121° C. for 20 minutes. 100 L of sugar feed was added to the sterilized NAGT medium using a steam sterilization connection. The completed NAGT medium was then degassed.

[0204] Example 12: Clinical trial design A first-in-human trial design is used to evaluate an orally administrable pharmaceutical composition containing a bacterial symbiont consisting of the bacterial strains Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187) offered for the prevention and treatment of allergic diseases.

[0205] The present study is designed as a phase 1b, multicenter, randomized, double-blind, placebo-controlled, parallel group, three-part study of a bacterial consortium consisting of the bacterial strains Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187) in multiply sensitized (to two or more allergens) and otherwise healthy human subjects (human subjects).

[0206] Circulating IgE levels (both total and specific levels), immune cell counts, fecal microbiome composition, fecal and plasma metabolic profiles The therapeutic function of bacterial composition A will be evaluated by measuring serum, fecal and plasma immune stimulatory potential (in vitro assays), as well as changes in symptom scores from baseline to the end of treatment.

[0207] The subjects are divided into three categories (see, for example, FIG. 29). The first category includes approximately 20 subjects aged 18-40 years, who are polysensitized to two or more allergens and who are otherwise healthy (male:female; approximately 1:1) (randomized 3:1 test:placebo). The second category includes approximately 20 subjects aged 12-17 years, who are polysensitized to two or more allergens and who are otherwise healthy (male:female; approximately 1:1) (randomized 3:1 test:placebo). The third category includes approximately 20 subjects aged 2-11 years, who are polysensitized to two or more allergens and who are otherwise healthy (male:female, approximately 1:1). The subjects are randomized 3:1 for Composition A versus placebo.

[0208] Treatment of human subjects consisted of twice-daily oral administration (approximately every 12 hours + / - 4 hours, by mixing with food or milk) of Composition A for 28 days. Each 1 mL dose of Composition A contained 5 x 10 of each of Lactobacillus crispatus (DSM 33187), Akkermansia muciniphila (DSM 33213), and Faecalibacterium prausnitzii (DSM 33185). 8 Contains CFU / bacterial species.

[0209] Composition A is a live biotherapy product (biologic product) containing three live bacterial strains, Lactobacillus crispatus (DSM 33187), Faecalibacterium prausnitzii (DSM 33185) and Akkermansia muciniphila (DSM 33213), each at 5 × 10 per dose. 8 CFU. Composition A is supplied as a single frozen glycerol stock containing all three bacterial species. Each dose of Composition A is provided in a 2 mL polypropylene screw cap vial with a silicone washer seal. The vial contains all three live bacterial strains suspended in a buffered glycerol solution. The buffered glycerol solution is composed of standard phosphate buffered saline (PBS, 137 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4 and 1.8 mM KH2PO4), 20% v / v glycerol and 0.1% w / w cysteine ​​as an antioxidant. The volume of a dose of Composition A is approximately 1 mL.

[0210] For purposes of this example, Composition A is stored at -70°C and a temperature log is maintained. Once provided to a human subject, Composition A is stored in a freezer at or below -18°C. To maintain the potency and purity of the product, a dose of Composition A is kept sealed in its cryovial (e.g., 2 mL cryovial) container prior to thawing for consumption. Frozen stocks of Composition A are thawed at room temperature for 5-10 minutes and used immediately as described in the dosing instructions.

[0211] Placebo treatment in this example consisted of twice-daily oral administration (approximately every 12±4 hours, by mixing with food or milk) of vehicle [Placebo: Phosphate-buffered saline (PBS) as described for product formulation, containing 20% ​​v / v glycerol and 0.1% w / w cysteine] for 28 days. Each 1 mL dose will be identical in volume to the test product. Frozen stocks are thawed at room temperature for 5-10 minutes. The contents of the vial are then immediately mixed into an appropriate amount (1-2 oz) of cooled or room temperature milk (including breast milk, liquid infant formula, cow's milk, almond milk, soy milk) or food such as applesauce and yogurt.

[0212] As shown in Figure 29, screening visits occur 28 to 7 days prior to day 1 (baseline visit). Dosing begins on day 1. Subjects are treated for 28 days, with subsequent visits on days 8, 15, 22, and 29. Follow-up visits occur on days 43 and 57. Each visit after baseline has a window of ±1 day.

Hematological variables include hematocrit, hemoglobin, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular volume, platelet count, red cell distribution width, red blood cell count, and white blood cell count (with differential). Urinalysis parameters include appearance (e.g., color and characteristics), bilirubin, urobilinogen, protein content, glucose level, ketones, leukocyte esterase, urinary blood, nitrites, pH, and specific gravity. Biochemical parameters included glucose levels (blood glucose levels), uric acid, BUN (blood urea nitrogen), creatinine, BUN / creatinine ratio, eGFR (estimated glomerular filtration rate), sodium, potassium, chloride, bicarbonate, calcium, albumin, total bilirubin, alkaline phosphatase levels, AST (aspartate aminotransferase) levels, ALT (alanine transaminase), gamma-glutamyltransferase (GGT), total cholesterol levels and triglyceride levels.

[0216] Example 13: Viability of frozen bacterial cells The viability of Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187) frozen in glycerol was investigated. Approximately 5 × 10 8 CFU of A. muciniphila (DSM 33213), approximately 5 × 10 8 CFU of F. prausnitzii (DSM 33185) and approximately 5 × 10 8CFU of Lactobacillus crispatus (DSM 33187) were mixed in glycerol and frozen. Frozen bacterial cells were stored at -70°C. Viability of bacterial cells was evaluated at 1, 2, 3, 6, 9 and 12 months after storage. Evaluations are shown in Table 22. [Table 25]

[0217] Example 14: Lyophilized Pharmaceutical Capsule and Liquid Composition Container Composition A as defined in Example 2 is encapsulated in a capsule using pharma- ceutically acceptable excipients. The capsule is a standard size 0 or size 1. The capsule is composed of a plant-derived material such as tapioca pullulan. It is starch-free, gluten-free and preservative-free. The capsule disintegrates at 37°C. More than 90% of the capsule dissolves within 60 minutes in water, a solution of pH=1.2, sodium acetate buffer USP (pH=4.5) or sodium phosphate buffer (pH=7.2). The capsule has a disintegration endpoint of 1.6 minutes measured at 37°C using deionized water. The capsule has an oxygen permeability (cm) of 0.5 or less as measured by the gas composition within the capsule. 3 / m 2 / day). The capsules are administered orally as shown in Figure 30. Composition A is also present in a 2 mL polypropylene screw cap vial and is administered orally as shown in Figure 30.

[0218] Example 15: Design of a clinical trial to prevent allergic conditions in infants and newborns Further testing of Composition A: Each dose was administered in equal amounts [5×10 8CFU / Akkermansia muciniphila (DSM 33213), Faecalibacterium prausnitzii (DSM 33185) and Lactobacillus crispatus (DSM 33187)] total 1.5 × 10 9 It contains CFU and a carbohydrate-based excipient and is compared to a placebo (an identical-looking excipient solution) in neonatal and infant subjects at high risk for developing allergic disease. One mL of Composition A or placebo is mixed into breast milk, formula, or food and administered orally (by mouth) once daily for 28 days (Part A) and 336 days (Part B).

[0219] Part A: As shown in Figure 31, infants aged 28 days to less than 12 months will be enrolled first for 28 days of treatment followed by an additional month of observation (off-treatment) to assess safety / tolerability, followed by neonatal enrollment (Part B). In Part A, eligible subjects will be randomized to either Composition A treatment or placebo treatment. Composition A treatment will consist of oral administration of Composition A (mixed with breast milk, formula or food) once daily for 28 days, and placebo treatment will consist of oral administration of placebo (mixed with breast milk, formula or food) once daily for 28 days. A total of 20 eligible infants will be enrolled in a 3:1 (15:5) randomization.

[0220] Part B: Neonates 7 days of age or younger are randomized to either Composition A treatment or placebo treatment as depicted in Figure 32. Composition A treatment consists of oral administration of Composition A (mixed with breast milk, formula or food) once daily for 336 days, and placebo treatment consists of oral administration of placebo (mixed with breast milk, formula or food) once daily for 336 days.

[0221] Eligible newborns will be enrolled in a 1:1 (112:112) randomization stratified by mode of delivery (vaginal or Caesarean section) and feeding method at enrollment (breast-fed or not breast-fed). Potentially eligible newborns will be identified during pregnancy or the first week after birth. Administration of Composition A or placebo will begin within 7 days of birth and continue for 1 year, followed by a 1-year observation period (off-treatment), followed by measurements at 10 visits (8 clinic visits and 2 telephone calls) over a period of 672 days from enrollment.

[0222] Immunological biomarkers of Composition A compared to placebo in neonatal and infant subjects Markers, additional fecal metabolic profiling and fecal microbiome analysis are measured. The therapeutic function of bacterial composition A is evaluated by determining circulating IgE levels (both total and specific levels), immune cell counts, fecal microbiome composition, fecal and plasma metabolic profiles, fecal and plasma immune stimulatory potential (in vitro analysis), and change in symptom scores from baseline to end of treatment.
