SOLID DOSAGE FORMS CONTAINING BACTERIA AND MICROBIAL EXTRACELLULAR VESICLES

SUMMARY

In certain aspects, provided herein are solid dosage forms of a pharmaceutical agent. In certain embodiments, such solid dose forms include capsules, tablets, and minitablets. In some embodiments, the capsules, tablets, or minitablets are coated with one layer of enteric coating or with two layers of enteric coatings (e.g., an inner enteric coating and an outer enteric coating). In some embodiments, the enterically-coated minitablets (with one layer of enteric coating or with two layers of enteric coatings) can be loaded into a capsule.

Aspects of the disclosure are based, in part, on the discovery that certain solid dosage forms of a pharmaceutical agent provide an increase in therapeutic efficacy and/or physiological effect as compared to other dosage forms of the pharmaceutical agent (e.g., as compared to the same dose of the pharmaceutical agent administered in a form that does not comprise the enteric coating, e.g., a non-enterically coated tablet or non-enterically coated minitablet or a suspension of biomass or powder). The solid dosage forms can be formulated to contain a lower dose (e.g., 1/10 or less of a dose) of the pharmaceutical agent than other dosage forms (e.g., as compared to the same dose of the pharmaceutical agent administered in a form that does not comprise the enteric coating, e.g., a non-enterically coated tablet or non-enterically coated minitablet or a suspension of biomass or powder), yet result in comparable therapeutic efficacy and/or physiological effect. Such solid dosage forms can alternatively be formulated to contain the same dose of a pharmaceutical agent as other dosage forms (e.g., as compared to the same dose of the pharmaceutical agent administered in a form that does not comprise the enteric coating, e.g., a non-enterically coated tablet or non-enterically coated minitablet or a suspension of biomass or powder), yet result in greater therapeutic efficacy or physiological effect (e.g., 10-fold or more therapeutic efficacy or physiological effect). The solid dosage forms of a pharmaceutical agent as described herein can provide release in the small intestine of the pharmaceutical agent contained therein. The solid dosage forms can be prepared to allow release of the pharmaceutical agent at specific locations in the small intestine. Release of the pharmaceutical agent at particular locations in the small intestine allows the pharmaceutical agent to target and affect cells (e.g., epithelial cells and/or immune cells) located at these specific locations, e.g., which can cause a local effect in the gastrointestinal tract and/or cause a systemic effect (e.g., an effect outside of the gastrointestinal tract).

In certain embodiments, the solid dosage forms of a pharmaceutical agent as described herein can be used to deliver a variety of pharmaceutical agents that can act on immune cells and/or epithelial cells in the small intestine to cause a systemic effect (e.g., an effect outside of the gastrointestinal tract) and/or can cause a local effect in the gastrointestinal tract.

In some embodiments, the pharmaceutical agent can be of bacterial origin (e.g., mixture of selected strains or components thereof, such as microbial extracellular vesicles (mEVs) of the mixture of selected strains). The pharmaceutical agent can be of bacterial origin (e.g., a single selected strain and/or components thereof, such as microbial extracellular vesicles (mEVs) of that single selected strain).

As described herein, improved therapeutic effects were seen with certain solid dosage forms of a pharmaceutical agent that contained one layer of enteric coating, as compared to the same dose of the pharmaceutical agent administered in a form that does not comprise the enteric coating, e.g., a non-enterically coated tablet or non-enterically coated minitablet or a suspension of biomass or powder.

In some embodiments, a solid dosage form described herein can provide, inter alia, a pharmaceutical agent (e.g., a formulation of a pharmaceutical agent) which enhances the pharmacological potency of the pharmaceutical agent by 10-fold or more in preclinical in vivo models, as compared to the same dose of the pharmaceutical agent administered in a form that does not comprise the enteric coating, e.g., a non-enterically coated tablet or non-enterically coated minitablet or a suspension of biomass or powder). For example, for a given level of therapeutic efficacy and/or physiological effect obtained with a comparator formulation of the pharmaceutical agent, the dose can be reduced (e.g., to 1/10 or less) when prepared in a solid dosage form described herein.

In some embodiments, or a given dose of a pharmaceutical agent, target engagement (e.g., in the small intestine) can be increased such that for a given dose of a pharmaceutical agent, target engagement (e.g., in the small intestine) can be increased for better efficacy when the pharmaceutical agent is prepared in a solid dosage form described herein.
