Pharmaceutical compositions comprising maralixibat and uses thereof

The present invention relates to pharmaceutical compositions and dosage forms comprising maralixibat, methods of administering the same, methods of preparing the same, and methods of treating cholestatic pruritus and cholestatic liver disease comprising administering pharmaceutical compositions and oral dosage forms of maralixibat.

Hypercholemia and cholestatic liver diseases are liver diseases associated with impaired bile secretion (i.e., cholestasis), associated with and often secondary to the intracellular accumulation of bile acids/salts in the hepatocyte. Hypercholemia is characterized by increased serum concentration of bile acid or bile salt. Cholestasis can be categorized clinicopathologically into two principal categories of obstructive, often extrahepatic, cholestasis, and nonobstructive, or intrahepatic, cholestasis. Nonobstructive intrahepatic cholestasis can further be classified into two principal subgroups of primary intrahepatic cholestasis that result from constitutively defective bile secretion, and secondary intrahepatic cholestasis that result from hepatocellular injury. Primary intrahepatic cholestasis includes diseases such as benign recurrent intrahepatic cholestasis, which is predominantly an adult form with similar clinical symptoms, and progressive familial intrahepatic cholestasis (PFIC) types 1, 2, 3, 4, 5, and 6, which are diseases that affect children.

Alagille syndrome is an inherited condition in which bile builds up in the liver. One of the major features of Alagille syndrome is liver damage caused by abnormalities in the bile ducts. Alagille syndrome is associated with abnormalities of the liver, heart, skeleton, eye, and kidneys and a characteristic facial appearance.

Cholestatic pruritus is an itching sensation that can lead to excessive scratching, rashes or lesions caused by scratching, sleep deprivation, depression, and suicidal ideations. Cholestatic pruritus is a symptom of cholestasis, which is the obstructing or disrupting of bile flow through the biliary system. This can be caused from problems in the liver, gallbladder, and/or biliary tract. These problems can be caused by biliary stricture, bile duct obstructions, liver diseases, hepatitis, pregnancy, parenteral nutrition, and medications. It may be caused by Alagille syndrome.

Maralixibat (as maralixibat chloride) is currently the only approved medication to treat pruritus in people with Alagille syndrome. It is known that maralixibat chloride inhibits apical sodium co-dependent bile acid transport (U.S. Pat. No. 5,994,391). Maralixibat is currently available as an oral solution.

There is a need for formulations and dosage forms of maralixibat having favorable dissolution and pharmacokinetic profiles, which also demonstrate good storage stability. Embodiments of the present disclosure are directed to this and other considerations.

It is further appreciated that certain features described herein, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination.

It is understood that the present embodiments encompass the use, where applicable, of stereoisomers, diastereomers and optical stereoisomers of the compounds, as well as mixtures thereof. Additionally, it is understood that stereoisomers, diastereomers, and optical stereoisomers of the compounds, and mixtures thereof, are within the scope of the embodiments. By way of non-limiting example, the mixture may be a racemate or the mixture may comprise unequal proportions of one particular stereoisomer over the other. Additionally, the compounds can be provided as substantially pure stereoisomers, diastereomers and optical stereoisomers (such as epimers).

The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended to be included within the scope of the embodiments unless otherwise indicated. Compounds that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods of preparation of optically active forms from optically active starting materials are known in the art, such as by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present embodiments. Cis and trans geometric isomers of the compounds are also included within the scope of the embodiments and can be isolated as a mixture of isomers or as separated isomeric forms. Where a compound capable of stereoisomerism or geometric isomerism is designated in its structure or name without reference to specific R/S or cis/trans configurations, it is intended that all such isomers are contemplated.

Resolution of racemic mixtures of compounds can be carried out by any of numerous methods known in the art, including, for example, chiral HPLC and fractional recrystallization using a chiral resolving acid which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization methods include, but are not limited to, optically active acids, such as the D and L forms of tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid, and the various optically active camphorsulfonic acids such as β-camphorsulfonic acid. Other resolving agents suitable for fractional crystallization methods include, but are not limited to, stereoisomerically pure forms of α-methylbenzylamine (e.g., S and R forms, or diastereomerically pure forms), 2-phenylglycinol, norephedrine, ephedrine, N-methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and the like. Resolution of racemic mixtures can also be carried out by elution on a column packed with an optically active resolving agent (e.g., dinitrobenzoylphenylglycine). Suitable elution solvent compositions can be determined by one skilled in the art.

Compounds may also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Examples of prototropic tautomers include, but are not limited to, ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, amide-imidic acid pairs, enamine-imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system including, but not limited to, 1H- and 3H-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, 1H- and 2H-isoindole, and 1H- and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution.

Compounds also include hydrates and solvates, as well as anhydrous and non-solvated forms.

Compounds can also include all isotopes of atoms occurring in the intermediates or final compounds. Isotopes include those atoms having the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium.

In some embodiments, the compounds, or salts thereof, are substantially isolated. Partial separation can include, for example, a composition enriched in the compound of the embodiments. Substantial separation can include compositions containing at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 97%, or at least about 99% by weight of the compound of the embodiments, or salt thereof. Methods for isolating compounds and their salts are routine in the art.

Although the disclosed compounds are suitable, other functional groups can be incorporated into the compound with an expectation of similar results. In particular, thioamides and thioesters are anticipated to have very similar properties. The distance between aromatic rings can impact the geometrical pattern of the compound and this distance can be altered by incorporating aliphatic chains of varying length, which can be optionally substituted or can comprise an amino acid, a dicarboxylic acid or a diamine. The distance between and the relative orientation of monomers within the compounds can also be altered by replacing the amide bond with a surrogate having additional atoms. Thus, replacing a carbonyl group with a dicarbonyl alters the distance between the monomers and the propensity of dicarbonyl unit to adopt an anti arrangement of the two carbonyl moiety and alter the periodicity of the compound. Pyromellitic anhydride represents still another alternative to simple amide linkages which can alter the conformation and physical properties of the compound. Modern methods of solid phase organic chemistry (E. Atherton and R. C. Sheppard, Solid Phase Peptide Synthesis A Practical Approach TRL Press Oxford 1989) now allow the synthesis of homodisperse compounds with molecular weights approaching 5,000 Daltons. Other substitution patterns are equally effective.

The compounds also include derivatives referred to as prodrugs.

Embodiments of various compounds and salts thereof are provided. Where a variable is not specifically recited, the variable can be any option described herein, except as otherwise noted or dictated by context.

Methods of Preparing Pharmaceutical Compositions

Provided herein is a method of preparing the pharmaceutical composition comprising: milling maralixibat, or a pharmaceutically acceptable salt thereof;

combining the milled maralixibat, or a pharmaceutically acceptable salt thereof, with the diluent, the glidant, the lubricant; and optionally the disintegrant to form an admixture; and compacting the admixture to form the pharmaceutical composition.

In some embodiments, the milling process applies energy through mechanical forces to break down larger particles into smaller sizes.

In some embodiments, the milling process is executed with grinding media, screen mills, conical mills, hammer mills, vibration mills, sieves, oscillating granulators, pegs, pebbles, or rods.

In some embodiments, the particles are passed through the milling device multiple times with or without decreasing mesh size depending on device.

In some embodiments, the particles are forced through the milling device and are torn or crushed.

In some embodiments, milling may also be referred to as grinding, granulation, size reduction, comminution, or pulverization.

In some embodiments, the milling is loop milling or pin milling.

In some embodiments, loop milling is performed with an oval chamber mill, spiral jet mill, or loop jet mill.

In some embodiments, loop milling uses pressurized gas to create high particle velocity and high-energy impact between particles and between the particles and the mill chamber.

In some embodiments, size reduction is achieved by particle-to-particle collisions.

In some embodiments, nitrogen is used as the loop milling gas.

In some embodiments, pin milling is performed with a pin mill, pin mill grinder, or disc mill.

In some embodiments, the pin mill grinder chamber consists of two discs or plates each containing circular rows of pins or vertical projections that are arranged in concentric circles moving past one another.

In some embodiments, either one or both disks of the pin mill are rotated at high speeds and the speed of one or both discs can be adjusted to vary the range of particle size.

In some embodiments, pin milling relies on particles repeatedly impacting pins as the material is fed into the space between the discs of the milling chamber.

In another embodiment, the milled maralixibat, or a pharmaceutically acceptable salt thereof, has a particle size distribution with a Dv90 of less than about 2500 μm.

In another embodiment, the milled maralixibat, or a pharmaceutically acceptable salt thereof, has a particle size distribution with a Dv90 of less than about 1500 μm.

In another embodiment, the milled maralixibat, or a pharmaceutically acceptable salt thereof, has a particle size distribution with a Dv90 of less than about 850 μm.

Generally, the compounds of this invention are administered in a therapeutically effective amount. The amount of the compound actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound-administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

The compounds of this invention can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can be found in Remington's Pharmaceutical Sciences.

The tablets or pills containing the compound of maralixibat or a pharmaceutically acceptable salt thereof can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the 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 permit 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.

The therapeutic dosage of the compounds of the invention can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compounds of the invention in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
