The present disclosure relates to: (a) processes for the preparation of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (referred to herein as “Compound 1”), (b) intermediates used in the preparation of Compound 1 and processes for preparing the intermediates; (c) solid state forms of Compound 1, (d) pharmaceutical compositions comprising one or more solid state forms of Compound 1, and, optionally, one or more additional therapeutic agents; (e) methods of treating Janus kinase-associated conditions (including rheumatoid arthritis) by administering one or more solid state forms of Compound 1 to a subject in need thereof; (f) kits comprising a first pharmaceutical composition comprising a solid state form of Compound 1, and, optionally, a second pharmaceutical composition comprising one or more additional therapeutic agents; (g) methods for the preparation of solid state forms of Compound 1; and (h) solid state forms of Compound 1 prepared in accordance with such methods.
(3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (“Compound 1”) was first disclosed in International Application WO2011/068881A1, which is herein incorporated by reference in its entirety. The compound has activity as a Janus kinase (“JAK”) inhibitor, particularly as a JAK-1 inhibitor. Clinical trials are ongoing to evaluate the use of the compound to treat rheumatoid arthritis.
The isolation and commercial-scale preparation of a solid state form of Compound 1 and corresponding pharmaceutical formulations having acceptable solid state properties (including chemical stability, thermal stability, solubility, hygroscopicity, and/or particle size), compound manufacturability (including yield, impurity rejection during crystallization, filtration properties, drying properties, and milling properties), and formulation feasibility (including stability with respect to pressure or compression forces during tableting) present a number of challenges that are discussed in greater detail below. Accordingly, there is a current need for one or more solid state forms of Compound 1 that have an acceptable balance of these properties and can be used in the preparation of pharmaceutically acceptable solid dosage forms.
Additionally, currently known processes for the preparation of Compound 1 involve the use of particularly hazardous reagents, such as trimethylsilyldiazomethane or diazomethane, and do not produce a crystalline product. There is thus also a need for a process for preparing Compound 1, and pharmaceutically acceptable salts thereof, that avoids the use of particularly hazardous reagents, and can produce a crystalline product and crystalline intermediates.
Additionally, sustained peak plasma concentrations can theoretically be achieved by means of sustained release matrix systems. However, when such systems are made of hydrophilic polymers, such as HPMC, they seldom provide pH independent drug release of pH-dependent soluble drugs, and they are normally incapable of attaining zero-order release except for practically insoluble drugs. Unexpectedly, is has been discovered that when tartaric acid is used as a pH-modifier in such a system, it allows Compound 1 to be released at a steady rate regardless of the pH of the environment.
In an unexpected finding, it was discovered that as a tablet containing the hydrophilic polymer matrix system erodes, Compound 1 reacts with the HPMC, creating a thicker gel layer which slows the release of Compound 1 from the tablet. The resulting gel layer provided an environment suitable for Compound 1 to dissolve.

This written description uses examples to disclose the invention and also to enable any person skilled in the art to practice the invention, including making and using any of the disclosed solid state forms or compositions, and performing any of the disclosed methods or processes. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they include equivalent elements.
Section headings as used in this section and the entire disclosure are not intended to be limiting.
Where a numeric range is recited, each intervening number within the range is explicitly contemplated with the same degree of precision. For example, for the range 6 to 9, the numbers 7 and 8 are contemplated in addition to 6 and 9, and for the range 6.0 to 7.0, the numbers 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9 and 7.0 are explicitly contemplated. In the same manner, all recited ratios also include all sub-ratios falling within the broader ratio.
The singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.
The term “about” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (i.e., having the same function or result). In many instances, the term “about” may include numbers that are rounded to the nearest significant figure.
The term “alkyl” refers to straight chained or branched hydrocarbons which are completely saturated. For purposes of exemplification, which should not be construed as limiting the scope of this invention, examples of alkyls include methyl, ethyl, propyl, isopropyl, butyl, pentyl, hexyl, and isomers thereof.
The term “alkenyl” refers to a hydrocarbon moiety containing two to eight carbons, including straight chained or branched hydrocarbons which contain one or more double bonds. Non-limiting examples of alkenyls are ethenyl, propenyl, and butenyl.
The term “amorphous” as applied to a compound refers to a state in which the material lacks long range order at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from solid to liquid properties occurs which is characterized by a change of state, typically second order (“glass transition”).
The term “anhydrate” as applied to a compound refers to a solid state wherein the compound contains no structural water within the crystal lattice.
The term “aryl” refers to a mono-, bi-, or tricyclic aromatic hydrocarbon radical. Examples include phenyl, naphthyl, biphenyl, and 1,2,3,4-tetrahydronaphthyl.
Unless the context requires otherwise, the terms “comprise,” “comprises,” and “comprising” are used on the basis and clear understanding that they are to be interpreted inclusively, rather than exclusively, and that Applicant intends each of those words to be so interpreted in construing this patent, including the claims below.
The term “crystalline” as applied to a compound refers to a solid phase in which the material has a regular ordered internal structure at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. Such materials when heated sufficiently will also exhibit the properties of a liquid, but the change from solid to liquid is characterized by a phase change, typically first order (“melting point”).
The term “crystalline purity” means the crystalline purity of a compound with regard to a particular crystalline form of the compound as determined by the powder X-ray diffraction analytical methods described in this application.
The term “crystallization” as used throughout this application can refer to crystallization and/or recrystallization depending upon the applicable circumstances relating to the preparation of the compound.

Compound 1 has the structure shown below:
Methods for making and using this compound are described, for example, in International Application WO 2011/068881A1, which is incorporated by reference in this application.
Previously disclosed processes for preparing Compound 1, and pharmaceutically acceptable salts thereof suffer from several drawbacks. In particular, these processes involve the use of particularly hazardous reagents, such as trimethylsilyldiazomethane or diazomethane, and/or do not produce a crystalline product. The processes of the present disclosure overcome these drawbacks by avoiding the use of these hazardous reagents, and producing crystalline intermediates, which aid in purification.
Compounds of the present disclosure may be prepared using synthetic transformations such as those illustrated in Schemes I-XVI. Starting materials are commercially available, may be prepared by the procedures described herein, by literature procedures, or by procedures that would be well known to one skilled in the art of organic chemistry (see, for example, Larock, R. C. “Comprehensive Organic Transformations: A Guide to Functional Group Preparations, 2nd edition”, 1999, Wiley-VCH or Greene, T. W. and Wuts, P. G. M. “Protective Groups in Organic Synthesis, 3rd Edition”, 1999, Wiley-Interscience).
A. Preparation of Compound 1
In one aspect, the present disclosure is directed to a process for preparing Compound 1, or a pharmaceutically acceptable salt thereof. A process for preparing Compound 1 is illustrated in Scheme I. Reaction of protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid (I) or a pharmaceutically acceptable salt thereof with trimethylsulfoxonium chloride gives sulfur ylide (II). Contacting sulfur ylide (II) with LiX and a sulfonic acid yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI). Removal of the protecting group and contacting the deprotected compound with an acid yields a pharmaceutically acceptable salt of (VII). Reacting the pharmaceutically acceptable salt of (VII) with 2,2,2-trifluoroethylamine produces Compound 1.
wherein:
The protecting group may be any suitable protecting group known in the art. In some embodiments, the protecting group is selected from the group consisting of carboxybenzyl, p-methoxybenzyl carbonyl, benzyl, p-methoxybenzyl, and 3,4-dimethoxyenzyl. In another embodiment, the protecting group is carboxybenzyl.
In another embodiment, R1 is —OR2, and R2 is methyl or ethyl. In such embodiments, the compound of formula (IV) is a compound of formula (IVa):
wherein R2 is methyl or ethyl. It has surprisingly been discovered that when R2 is ethyl or methyl, the compound of formula (V) and subsequent downstream compounds can be isolated as crystalline solids, which aids in purification of these intermediates. In contrast, previously known processes, which use compounds where R2 is t-butyl, result in formation of compounds of formula (V) which are isolated as amorphous solids.
In certain embodiments, a pharmaceutically acceptable salt of a compound of the compound of formula (I) is used in the reaction of step (a). In one embodiment, the pharmaceutically acceptable salt of the compound of formula (I) is selected from the group consisting of the naphthalenethane amine salt (Ia) and the dicyclohexylamine salt (Ib)
wherein Cbz is carboxybenzyl.
In one embodiment, the pharmaceutically acceptable salt of compound (VII) is selected from the group consisting of (VIIa), (VIIb), and (VIIc)
Another process for preparing Compound 1 is illustrated in Scheme Ia. Reaction of (3R,4S)-1-((benzyloxy)carbonyl)-4-ethylpyrrolidine-3-carboxylate dicyclohexylamine salt (Ib) with trimethylsulfoxonium chloride in the presence of carbonyldiimidazole and a strong base gives sulfur ylide (IIa). Contacting sulfur ylide (IIa) with lithium bromide and a sulfonic acid yields the corresponding bromomethyl ketone (IIIa). Reaction of (IIIa) with alkyl 5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-ylcarbamate (IVa) in the presence of lithium tert-butoxide yields (Va). Cyclization of (Va) in the presence of a perfluoro acid anhydride and an organic base produces (VIa). Removal of the carboxybenzyl protecting group and contacting the deprotected compound with hydrochloric acid yields the pharmaceutically acceptable salt (VIIa). Reacting the pharmaceutically acceptable salt (VIIa) with 2,2,2-trifluoroethylamine produces Compound 1.

The resulting solution is slowly added (e.g., over 15 minutes) to a suspension of the trimethylsulfoxonium chloride, strong base, and solvent, while maintaining the internal temperature below −1° C. In another embodiment, the reaction is quenched and the resulting compound of formula (II) or (IIa) is isolated prior to step (b).
In some embodiments, the reaction of step (a) may further involve contact of (Ia) or (Ib) with an acid prior to reaction with the trimethylsulfoxonium chloride, in order to extract the amine to obtain a compound of formula (I). Suitable acids include any mineral acid or organic acid, such as phosphoric acid, hydrochloric acid (HCl), acetic acid (HOAc), citric acid, and the like. The compound of formula (I) may subsequently be taken up in a suitable solvent, and reacted with trimethylsulfoxonium chloride, as described herein. In one embodiment, a pharmaceutically acceptable salt of a compound of formula (I) is used in step (a), wherein the pharmaceutically acceptable salt is (Ia) or (Ib), and the reaction of step (a) is conducted according to the procedure set forth in Step A of Example 3.

The reaction of step (c) may be conducted in any suitable solvent including, but not limited to dimethylacetamide, tetrahydrofuran, dichloromethane, ethyl acetate, heptanes, and combinations thereof.
More particularly, in certain embodiments, the base is added to a cooled suspension of the compound of formula (III) or (IIIa) in a solvent. The resulting solution is stirred for about 30 minutes to about 12 hours, or about 30 minutes, and cooled to about −20° C. to about 0°, or about −10° C. In one embodiment, the solution is stirred for about 30 minutes and cooled to about −20° C. to about 0°. A solution of a compound of formula (IV) or (IVa) in a solvent is slowly added (e.g., over 30 minutes), and the resulting mixture is stirred for about 30 minutes to about 6 hours, or about 30 minutes, at a temperature of about −20° C. to about 0° C., or about −10° C. In one embodiment, following addition of the solution of the compound of formula (IV) or (IVa) in a solvent, the resulting mixture is stirred for about 30 minutes at a temperature of about −10° C. In one embodiment, the reaction is quenched, and, in some embodiments, the resulting product (V) or (Va) is isolated prior to step (d).
In step (d) of Schemes I and Ia, a compound of formula (V) or (Va) is contacted with a perfluoro acid anhydride and an organic base to form a compound of formula (VI) or (VIa), respectively. Non-limiting examples of suitable organic bases include pyridine, triethylamine, and combinations thereof. Examples of suitable perfluoro acid anhydrides include trifluoroacetic anhydride, pentafluoropropionic anhydride, heptafluorobutyric anhydride, and combinations thereof. In certain embodiments, the organic base is pyridine and the perfluoro acid anhydride is trifluoroacetic anhydride. In other embodiments, the organic base is triethylamine, and the perfluoro acid anhydride is pentafluoropropionic anhydride. Suitable solvents for use in step (d) include, but are not limited to acetonitrile, toluene, and combinations thereof.
More particularly, in certain embodiments, the organic base and the perfluoro acid anhydride are charged into a solution of a compound of formula (V) or (Va) in solvent. The resulting mixture is warmed to about 55° C. to about 75° C., or about 55° C., and stirred for about 4 hours to about 18 hours, or about 6 hours. In one embodiment, the mixture of perfluoro acid anhydride and the compound of formula (V) or (Va) is warmed to about 55° C. and stirred for about 4 hours to about 18 hours. In one embodiment, the mixture is stirred for about 6 hours. Upon completion of the reaction, in some embodiments, the reaction mixture may be cooled, and concentrated prior to contacting with a hydroxide solution to quench excess reagents, and remove the tosyl protecting group. Suitable hydroxide solutions include a sodium hydroxide (NaOH) solution, a potassium hydroxide (KOH) solution, and the like. The resulting mixture may be stirred at room temperature to about 85° C., including at about 55° C., for about 30 minutes to about 8 hours. In one embodiment, the mixture is stirred for about 1 hour. Upon completion, the solvent may optionally be removed and switched to methanol, ethanol, isopropanol, or other suitable solvents prior to step (e).
In step (e) of Schemes I and Ia, a compound of formula (VI) or (VIa) is deprotected, and a pharmaceutically acceptable salt of compound (VII), such as (VIIa), (VIIb), or (VIIc) is formed. The protecting group on the compound of formula (VI) or (VIa) may be removed using any suitable means known in the art. In one embodiment, deprotection occurs by contacting the compound of formula (VI) or (VIa) with palladium on carbon (e.g., Pd/C or Pd(OH2)/C) under hydrogen pressure. In other embodiments, deprotection occurs by contacting the compound of formula (VI) or (VIa) with an acid. Non-limiting examples of suitable acids include hydrochloric acid (HCl), hydrobromic acid (HBr), hydrobromic acid in acetic acid (e.g., HBr/HOAc), and the like. In other embodiments, deprotection occurs by subjecting the compound of formula (VI) or (VIa) to heating, e.g., at a temperature of from room temperature to about 85° C., including about 50° C. Upon deprotection, the compound of formula (VII) is contacted with the appropriate acid (e.g., hydrochloric acid or p-toluenesulfonic acid) to form the pharmaceutically acceptable salt.
Step (e) may occur in any suitable solvent including, but not limited to ethanol, isopropyl acetate, ethyl acetate, and combinations thereof.
More particularly, in some embodiments, palladium on carbon and the compound of formula (VI) or (VIa) in solvent are mixed under hydrogen pressure at about 1 psig to about 100 psig.

The step (f) reaction may be conducted in any suitable solvent including, but not limited to, tetrahydrofuran, ethyl acetate, heptanes, ethanol, water, and combinations thereof.
More particularly, in certain embodiments, 2,2,2-trifluoroethyl amine is added slowly (e.g., over 20 minutes) to a slurry of CDI in solvent, while maintaining an internal temperature of less than 30° C. The resulting solution is stirred for about 10 minutes to about 12 hours, and in one embodiment for about 1 hour, to form an imidazolide solution. The pH of a biphasic mixture of the pharmaceutically acceptable salt from step (e) in buffer and solvent is adjusted to about 7 to about 11, and in one embodiment to about 9, by addition of abase. The imidazolide solution is added, and the resulting mixture is mixed at about 25° C. while maintaining a pH of about 9 by portionwise addition of base for about 30 minutes to about 18 hours.

Contacting sulfur ylide (II) with LiX and a sulfonic acid yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI).

In step (h) of Scheme II, Compound 1 is contacted with L-tartaric acid to form the corresponding tartrate salt (step (h)). Formation of the tartrate salt advantageously aids in removal of impurities prior to isolation of the freebase. In one embodiment, the tartrate salt may be formed using the procedure described in Example 8, Method B, only without drying the tartrate salt prior to step (i). The tartrate salt is subsequently converted back to the freebase form (step (i)) to produce Compound 1.

Reaction of protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid (I) with trimethylsulfoxonium chloride gives sulfur yilde (II). Contacting sulfur yilde (II) with an anhydrous source of HBr or HCl yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI). Removal of the protecting group and contacting the deprotected compound with an acid yields a pharmaceutically acceptable salt of (VII). Reacting the pharmaceutically acceptable salt of (VII) with 2,2,2-trifluoroethylamine produces Compound 1.
wherein:

Contacting sulfur yilde (IIa) with an anhydrous source of HBr yields the corresponding bromomethyl ketone (IIIa). Reaction of (IIIa) with alkyl 5-tosyl-5H-pyrrolo[2,3-b]pyrazine-2-ylcarbamate (IVa) in the presence of lithium tert-butoxide yields (Va). Cyclization of (Va) in the presence of a perfluoro acid anhydride and an organic base produces (VIa). Removal of the carboxybenzyl protecting group and contacting the deprotected compound with hydrochloric acid yields the pharmaceutically acceptable salt (VIIa). Reacting the pharmaceutically acceptable salt (VIIa) with 2,2,2-trifluoroethylamine produces Compound 1.
wherein:
In step (a) of Schemes III and IIIa, (XIa) or (XI) (which may be prepared as described in Scheme V) is converted to (I) or (XII), respectively. In particular, in step (a), compound (XI) or (XIa) may be contacted with a catalyst, such as a ruthenium catalyst. Any catalyst comprising a chiral phosphine may be used.

In another embodiment, the present disclosure is directed to compound (VII):
or a pharmaceutically acceptable salt thereof.
In one embodiment, the pharmaceutically acceptable salt of (VII) is selected from the group consisting of (VIIa), (VIIb), and (VIIc):
In some embodiments, any of the processes for preparing (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide that are disclosed herein may further comprise forming one of the solid state forms described herein in Section III.
The present disclosure also relates to solid state forms of Compound 1. As with all pharmaceutical compounds and compositions, the chemical and physical properties of Compound 1 are important in its commercial development. These properties include, but are not limited to: (1) packing properties such as molar volume, bulk density and hygroscopicity, (2) thermodynamic properties such as melting temperature, vapor pressure and solubility, (3) kinetic properties such as dissolution rate and stability (including stability at ambient conditions, especially to moisture and under storage conditions), (4) surface properties such as surface area, wettability, interfacial tension and shape, (5) mechanical properties such as hardness, tensile strength, compactibility, handling, flow and blend; and (6) filtration properties. These properties can affect, for example, the processing and storage of the compound and pharmaceutical compositions comprising the compound.
Solid state forms of Compound 1 that improve upon one or more of these properties relative to other solid state forms of the compound are desirable. Isolating pharmaceutically acceptable solid state forms of the compound that can be manufactured and formulated on a commercial-scale has been a challenge.
The Amorphous Freebase form of Compound 1 generally has greater solubility, and increased bioavailability relative to most of the corresponding crystalline forms of the compound. The Amorphous Freebase also has acceptable chemical stability. However, it is hygroscopic, and environmental controls potentially are required to ensure appropriate control of potency and water content during storage, dispensing, and handling of the Amorphous Freebase. In addition, the Amorphous Freebase exhibits an oiling-out limit close to the solubility curve during manufacturing.
Crystalline Hydrochloride Solvate Form AA, crystalline Hydrochloride Solvate Form BB, and crystalline Hydrochloride Solvate Form CC generally convert to an amorphous hydrochloride upon ambient drying. The resulting amorphous hydrochloride is hygroscopic. Yields obtained for each of the crystalline hydrochlorides generally have been low. Hydrochloride Solvate Form AA, Hydrochloride Solvate Form BB, and Hydrochloride Solvate form CC may not be suitable for large scale manufacturing.
The crystalline L-Maleate forms generally may be less chemically stable than the Amorphous Freebase, the Freebase Hydrate Form C, and the Tartrate Hydrate, and may not exhibit pharmaceutically acceptable stability for use as an active ingredient in a pharmaceutical dosage form.
The Tartrate Hydrate form has acceptable chemical stability, high solubility, generally good impurity rejection during isolation and is not hygroscopic. However, the Tartrate Hydrate presented challenges because of lack of physical stability which also impacted manufacturing. The Tartrate Hydrate dehydrated into Amorphous at low relative humidity and high temperature, e.g., <10% RH at 25° C. Shearing and compression potentially cause conversion to the amorphous tartrate, and therefore it is not suitable for compressing into tablet form. Additionally, the filter cake solidified during drying, resulting in the need for additional controls during drying.
Freebase Hydrate Form B has been manufactured on a large scale without the need for labor-intensive and expensive techniques such as spray-drying. It also provided for appropriate control of the bulk properties of the Amorphous Freebase. However, the Amorphous Freebase exhibited poor impurity rejection when isolated via Freebase Hydrate Form B, and required a dry environment for storage and control of relative humidity during manufacturing and packaging.
The Freebase Hydrate Form B was not physically stable. It desolvated (or dehydrated) and converted to the Amorphous Freebase upon drying. Although the Freebase Hydrate Form B generally did not exhibit pharmaceutically acceptable physical stability for use as an active ingredient in a pharmaceutical dosage form, it may be a useful intermediate in the preparation of other solid state forms such as the Amorphous Freebase.
After years of experimentation, Freebase Hydrate Form C was serendipitously discovered when attempting to scale up the Amorphous Freebase. It offers many surprising and superior properties over the Amorphous Freebase, the Tartrate Hydrate and other forms of Compound 1.
Freebase Hydrate Form C generally exhibits excellent chemical stability, physical stability, and solid state properties, including low hygroscopicity and prismatic morphology. Freebase Hydrate Form C has improved bulk properties such as powder flow, bulk density, which are beneficial in the formulation process. In addition, Freebase Hydrate Form C offers at least the following unexpected advantages over the other forms: 1) efficient purification is obtained since there is no need to use the tartrate crystal; 2) the seeding step is straightforward since Freebase Hydrate Form C can be stored at normal conditions; 3) the drying step can be carried out at normal conditions with standard equipment since no dehydration occurs up to around 110° C.; 4) Freebase Hydrate Form C can be crystallized in different particle sizes. Large-scale manufacture of the Freebase Hydrate Form C is relatively straightforward with minimal scaling, good yield, good impurity rejection, fast filtration, conventional drying, and minimal milling issues. In addition, Freebase Hydrate Form C can be grown into different particle sizes.
Freebase Anhydrate Form D can be manufactured only when the water content of the crystallization solvent is low, and will convert to Freebase Hydrate Form C in solutions at high water content. The manufacture of Freebase Anhydrate Form D thus requires strict control of water content. Freebase Anhydrate Form D is slow to crystallize, and difficult to manufacture in higher yield. This anhydrate is reversibly hygroscopic (up to 1.8% water at 90% RH at 25° C.), and is metastable relative to Freebase Hydrate Form C at typical environmental conditions (e.g., above 2.4% RH at 23° C.) used during storage for downstream processing. Freebase Hydrate Form C will convert to Freebase Anhydrate Form D in a solution of ethyl acetate with low water content.
The sections below discuss solid state forms that have been identified and selected properties of those solid state forms.
A. Amorphous Freebase
In one embodiment, the solid state form is amorphous Compound 1 (the “Amorphous Freebase”). In one aspect, the Amorphous Freebase comprises less than about 13% by weight water. In another aspect, the Amorphous Freebase comprises less than about 12% by weight water. In another aspect, the Amorphous Freebase comprises less than about 10% by weight water. In another aspect, the Amorphous Freebase comprises less than about 9% by weight water. In another aspect, the Amorphous Freebase comprises less than about 8% by weight water. In another aspect, the Amorphous Freebase comprises less than about 7% by weight water. In another aspect, the Amorphous Freebase comprises less than about 6% by weight water. In another aspect, the Amorphous Freebase comprises less than about 5% by weight water. In another aspect, the Amorphous Freebase comprises less than about 4% by weight water. In another aspect, the Amorphous Freebase comprises less than about 3% by weight water. In another aspect, the Amorphous Freebase comprises less than about 2% by weight water. In another aspect, the Amorphous Freebase comprises less than about 1% by weight water. In another aspect, the Amorphous Freebase has a glass transition temperature onset at about 119° C. In another aspect, the Amorphous Freebase has a glass transition temperature midpoint at about 122° C. In another aspect, the Amorphous Freebase has a glass transition temperature onset at about 119° C. and a glass transition temperature midpoint at about 122° C. The Amorphous Freebase is further described in the Examples of the application.
The Amorphous Freebase generally has greater solubility, and increased bioavailability, relative to the corresponding crystalline forms of the compound. The Amorphous Freebase also has acceptable chemical stability. For example, when chemical stability was evaluated in closed vials at 30° C./65% relative humidity and 40° C./75% relative humidity over 12 weeks, and at 50° C./75% relative humidity over 6 weeks, no degradation of the Amorphous Freebase was observed in the closed vials under any of those conditions. In addition, the Amorphous Freebase exhibits acceptable stability to light and peroxide. The Amorphous Freebase, however, is hygroscopic and can comprise as much as 12% by weight water at 25° C./90% relative humidity. Environmental controls potentially are required to ensure appropriate control of potency and water content during storage, dispensing, and handling of the Amorphous Freebase.
The Amorphous Freebase can be prepared, for example, using anti-solvent crystallization to prepare the Freebase Solvate Form A or Freebase Hydrate Form B (described below) followed by dehydration or desolvation to yield the Amorphous Freebase. This crystallization/dehydration/desolvation method allows for the large-scale manufacture of the Amorphous Freebase without the need for labor-intensive and expensive techniques such as spray-drying. It also provides for appropriate control of the bulk properties of the Amorphous Freebase (i.e., particle size, flow properties etc.). When the Amorphous Freebase is prepared by desolvation of the Freebase Solvate Form A or dehydration of the Freebase Hydrate Form B, the Amorphous Freebase generally retains the morphology of the Freebase Solvate Form A or Freebase Hydrate Form B (i.e., blades with hexagonal crystal faces when prepared by dehydration of Freebase Hydrate Form B, or irregular when desolvated from Freebase Solvate Form A).
The process volumes required for crystallization during the large-scale manufacture of the Freebase Solvate Form A or Freebase Hydrate Form B generally are within conventional processing volumes, but impurity rejection potentially may be lower than desired. Drying and dehydration/desolvation of the Freebase Hydrate Form B/Freebase Solvate Form A to the Amorphous Freebase generally can be carried out with standard equipment under conventional conditions and the isolated Amorphous Freebase typically can be co-milled without adversely impacting the amorphous state.

In one embodiment, the Tartrate Hydrate has an X-ray diffraction pattern as previously described above; a thermogravimetric analysis profile showing a weight loss of about 11.8% to about 12.2% between about 25° C. and 160° C. when heated at a rate of 10° C./minute; a differential scanning calorimetry profile comprising an endotherm between about 60° C. and about 100° C. when heated at a rate of 10° C./minute; and a moisture sorption isotherm profile showing a weight gain of about 1% to about 2% when relative humidity is increased from about 10% relative humidity to about 90% relative humidity at a temperature of 25° C.
The Tartrate Hydrate has acceptable chemical stability and exhibits acceptable stability to light and peroxide. For example, when chemical stability was evaluated in closed vials at 30° C./65% relative humidity and 40° C./75% relative humidity over 12 weeks, and at 50° C./75% relative humidity over 6 weeks, no degradation of the Tartrate Hydrate was observed in the closed vials under any of the conditions. The Tartrate Hydrate has good solubility (BCS Class I) and is not hygroscopic. The Tartrate Hydrate, however, potentially will convert to an amorphous tartrate below 10% relative humidity, when heated, or when compressed or under shear.
The Tartrate Hydrate can be manufactured, for example, using anti-solvent crystallization. Impurity rejection during the large-scale manufacture of the Tartrate Hydrate generally is good, but scaling may be greater than desired and specific anti-solvent addition controls and process volume restrictions potentially may be required. In addition, appropriate control of the filtration, washing, and drying steps may be required to minimize consolidation of the wet cake and formation of hard lumps in the isolated material. For example, control of the relative humidity (e.g., greater than 10% and less than 100% relative humidity), temperature (e.g., crystallization at about 10° C. works well), and mixing rate may be required during drying to minimize the formation of hard lumps in the isolated material. Insufficient control of the drying conditions potentially will produce a consolidated, harder material that may be difficult to break up during subsequent processing. As previously noted, shearing and compression potentially will cause conversion to the amorphous tartrate. The dried material typically is milled with mechanical impact mills (e.g., Fitzmills and pin mills) because shear-based mills (e.g., comills) can lead to loss of crystallinity. In addition, loss of crystallinity potentially can result from pressure or compression forces during formulation (such as would be required for tableting).

In another aspect, the crystalline hydrochloride corresponds to crystalline Hydrochloride Solvate Form BB. In another aspect, the crystalline hydrochloride corresponds to crystalline Hydrochloride Solvate Form CC. Hydrochloride Solvate Form AA, Hydrochloride Solvate Form BB, and Hydrochloride Solvate Form CC are further described in the Examples of the application.
Hydrochloride Solvate Form AA, Hydrochloride Solvate Form BB, and Hydrochloride Solvate Form CC appear to be solvates and generally convert to an amorphous hydrochloride upon ambient drying. The resulting amorphous hydrochloride is hygroscopic. Yields obtained for each of the crystalline hydrochlorides generally have been in the 10% to 15% range.
G. Crystalline L-Maleate
In another embodiment, the solid state form is a crystalline L-maleate of Compound 1. In one aspect, the crystalline L-maleate corresponds to crystalline L-Maleate Form AAA. In another aspect, the crystalline L-maleate corresponds to crystalline L-Maleate Form BBB. L-Maleate Form AAA and L-Maleate Form BBB are further described in the Examples of the application.
Because L-maleic acid will react with Compound 1, the L-Maleate Form AAA and L-Maleate Form BBB generally are less chemically stable than the Amorphous Freebase, the Freebase Hydrate Form C, and the Tartrate Hydrate and do not exhibit pharmaceutically acceptable stability for use as an active ingredient in a pharmaceutical dosage form.

Statistical significance is manifested by a p value of less than 0.05, or less than 0.01.
Components of the ACR responses are well known in the art, and may include the median number of tender joints, the median number of swollen joints, physician global assessment such as one measured by visual analog scale (VAS), patient global assessment such as one measured by visual analog scale, pain such as one measured by visual analog scale, disability index of the Health Assessment Questionnaire (HAQ-DI score), and C-reactive protein (CRP) (mg/dL).
In certain embodiments, an ACR20 response is determined based on a 20% or greater improvement in tender joint count (TJC) and swollen joint count (SJC) and greater than or equal to 3 of the 5 measures of Patient's Assessment of Pain (VAS), Patient's Global Assessment of Disease Activity (VAS), Physician's Global Assessment of Disease Activity (VAS), HAQ-DI, or high sensitivity C-reactive protein (hsCRP). In some embodiments, an ACR50 response is determined based on a 50% or greater improvement in TJC and SJC and greater than or equal to 3 of the 5 measures of Patient's Assessment of Pain (VAS), Patient's Global Assessment of Disease Activity (VAS), Physician's Global Assessment of Disease Activity (VAS), HAQ-DI, or hsCRP. An ACR70 response is determined based on a 70% or greater improvement in TJC and SJC and greater than or equal to 3 of the 5 measures of Patient's Assessment of Pain (VAS), Patient's Global Assessment of Disease Activity (VAS), Physician's Global Assessment of Disease Activity (VAS), HAQ-DI, or hsCRP. In certain embodiments, the ACR20, ACR50, or ACR70 response occurs by week 12 of treatment.
In certain embodiments, a DAS28 (disease activity score based on the 28 joints examined) score is determined as a composite score derived from four of the following measures: examination of joints for swelling and tenderness, global scores of pain and overall status, blood markers of inflammation (e.g. ESR (erythrocyte sedimentation rate) and CRP (C reactive protein), referred to herein as DAS28(CRP)), questionnaires (e.g. the HAQ (health assessment questionnaire) which assess function) and X-rays and other imaging techniques such as ultrasound and MRI.
In certain embodiments, structural joint damage can be assessed radiographically and expressed as change in Total Sharp Score (TSS) and its components, the erosion score and Joint Space Narrowing (JSN) score, for example, at week 12 compared to baseline, or at week 24 as compared to baseline.
In certain embodiments, improvement in signs and symptoms of the disease can be measured by patient physical function response, such as disability index of Health Assessment Questionnaire (HAQ-DI), and/or the health-outcomes as assessed by The Short Form Health Survey (SF 36). In one embodiment, improvement in signs and symptoms of the disease is measured by HAQ-DI, including the minimal clinically important difference (MCID) of −0.22. Improvement can also be measured by one or both of Physical Component Summary (PCS) and the Mental Component Summary (MCS). Improvements can further be measured by Work Instability Scale for RA (RA-WIS) (see Gilworth et al., Arthritis & Rheumatism (Arthritis Care & Research) 49(3): 349-354, 2003, incorporated by reference).

The solid state form can be combined with IL-11 or anti-cytokine antibodies, for example, fonotolizumab (anti-IFNg antibody), or anti-receptor receptor antibodies, for example, anti-IL-6 receptor antibody and antibodies to B-cell surface molecules. The solid state form may also be used with UP 394 (abetimus), agents that deplete or inactivate B-cells, for example, Rituximab (anti-CD20 antibody), lymphostat-B (anti-BlyS antibody), TNF antagonists, for example, anti-TNF antibodies, adalimumab (such as HUMIRA™ brand adalimumab), infliximab such as CA2 (REMICADE™ brand infliximab), CDP 571, TNFR-Ig constructs, etanercept such as p75TNFRIgG (ENBREL™ brand etanercept) and lenercept such as p55TNFRIgG (LENERCEPT™).
The solid state form may also be combined with an immune modulator for CD4+CD25+Treg cells. Treg cells are essential for maintaining normal immune homeostasis. In patients with autoimmune diseases, reduced numbers or functional impairment of Treg cells has been observed, leading to loss of this finely-tuned mechanism. A humanized agonistic monoclonal antibody, BT-061, binds to a unique epitope of human CD4, and induces Treg-specific signaling events that lead to their functional activation. Pre-clinical data using isolated Treg cells and rheumatoid arthritis synovial fluid indicate that BT-061 leads to suppression of CD4+ and CD8+T effector cell proliferation, reduction of the expression of pro-inflammatory cytokines, and increase in the production of the anti-inflammatory cytokine TGFβ. Thus similar immune modulators for CD4+CD25+Treg cells can also be co-administered with a compound of the invention for treating any of the inflammatory disease/disorder, or an autoimmune disease/disorder described herein, including but not limited to rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, psoriasis, ulcerative colitis, systemic lupus erythematosus, lupus nephritis, diabetic nephropathy, dry eye syndrome, Sjogren's syndrome, alopecia areata, vitiligo, or atopic dermatitis. In certain embodiments, the combination treats rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis, including moderately to severely active rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis. In certain embodiments, the rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis patient being treated has inadequately responded to or has discontinued therapy due to loss of response to or intolerance to a first line therapy (such as a DMARD, including methotrexate) or an anti-TNFα therapy.
In certain embodiments, the immune modulator has one or more (or all) of the following properties: (1) activates a subset of CD4+ T cells comprising CD4+CD25+ regulatory T cells (Treg), or CD4+CD25+Treg cells; (2) binds only to a special epitope of the human CD4 antigen (such as the IgG-like C2 type 1 domain of CD4), which said epitope of human CD4 may be bound by a mouse IgG1 anti-CD4 monoclonal antibody B-F5 or a humanized version thereof, such as the BT-061 hB-F5 antibody tregalizumab as described in U.S. Pat. No. 7,452,981 (incorporated herein by reference, including all sequences of the VH and VL chains disclosed therein); (3) provides an activation signal to naturally occurring Treg cells but does not activate conventional T cells (e.g., CD4+ T cells that are not activated in (1), CD8+ cytotoxic T cells, etc.); and (4) is not a depleting anti-CD4 antibody that depletes CD4+ T cells, and/or does not appreciably trigger ADCC or CDC.
The present disclosure further relates, in part, to compositions comprising Compound 1 or a pharmaceutically acceptable salt thereof, or one or more solid state forms of Compound 1. Although the solid state form may be administered alone or in the form of a pharmaceutical composition, administration generally will be in the form of a pharmaceutical composition. In some embodiments, the composition comprises Compound 1 or a pharmaceutically acceptable salt thereof or a solid state form of Compound 1 in association with a pharmaceutically acceptable carrier. The preferred composition depends on the method of administration, and typically comprises one or more conventional pharmaceutically acceptable carriers, adjuvants, and/or vehicles (together referred to as “excipients”). Such compositions can be formulated for various routes of systemic or local delivery for example, by oral administration, topical administration, transmucosal administration, rectal administration, intravaginal administration, or administration by subcutaneous, intrathecal, intravenous, intramuscular, intraperitoneal, intranasal, intraocular or intraventricular injection.
Solid dosage forms for oral administration include, for example, capsules, tablets, pills, powders, and granules.

Such compositions also can comprise, for example, wetting, emulsifying, suspending, sweeting and flavoring agents.
Parenteral administration includes subcutaneous injections, intravenous injections, intramuscular injections, intrasternal injections, and infusion. Injectable preparations (e.g., sterile injectable aqueous or oleaginous suspensions) can be formulated according to the known art using suitable dispersing, wetting agents, and/or suspending agents. Acceptable vehicles and solvents include, for example, water, 1,3-butanediol, Ringer's solution, isotonic sodium chloride solution, bland fixed oils (e.g., synthetic mono- or diglycerides), fatty acids (e.g., oleic acid), dimethyl acetamide, surfactants (e.g., ionic and non-ionic detergents), and/or polyethylene glycols.

The pH may be adjusted, if necessary, with a suitable acid, base, or pH modifier.
Suppositories for rectal administration can be prepared by, for example, mixing a compound or salt of the invention with a suitable nonirritating excipient that is solid at ordinary temperatures, but liquid at the rectal temperature, and will therefore melt in the rectum to release the drug. Suitable excipients include, for example, cocoa butter; synthetic mono-, di-, or triglycerides, fatty acids, and/or polyethylene glycols.
Compound 1 or the solid state forms of the present disclosure can be formulated for administration topically to the skin or mucosa, i.e., dermally or transdermally. Such administration can include the use, e.g., of transdermal patches or iontophoresis devices.
Besides those representative dosage forms described above, pharmaceutically acceptable excipients and carriers are generally known to those skilled in the art and are thus included in the instant invention.

In one embodiment, the target or label amount of active ingredient (e.g., Compound 1) provided for inclusion in the compositions of the present disclosure refers to the amount of Compound 1 freebase. For instance, as discussed herein, Compound 1 may be prepared in several solid state forms including Amorphous Freebase, crystalline solvates and hydrates (e.g., Freebase Solvate Form A, Freebase Hydrate Form B), crystalline hemihydrates (e.g., Freebase Hydrate Form C), crystalline anhydrate (e.g., Freebase Anhydrate Form D), crystalline tartrate (e.g., Tartrate Hydrate), crystalline hydrochloride (e.g., Hydrochloride Solvate Form AA, Hydrochloride Solvate Form BB, Hydrochloride Solvate Form CC), and crystalline L-maleate (e.g., L-Maleate Form AAA, L-Maleate Form BBB, L-Maleate Form CCC). It should be understood that in embodiments, where the dosage unit composition comprises, e.g., a solvate, hydrate, hemihydrate, tartrate, hydrochloride, or L-maleate of Compound 1, the amount of solvate, hydrate, hemihydrate, tartrate, hydrochloride, or L-maleate of Compound 1 present in the dosage unit composition may be slightly higher than the target amount of Compound 1 (active ingredient), and preferably will be present in the dosage unit composition in an amount sufficient to deliver the target amount of Compound 1 freebase equivalent to a subject. For example, if the target amount of Compound 1 (active ingredient) in a dosage unit composition is 15 mg, a dosage unit composition comprising, for example, Freebase Hydrate Form C, may comprise the Freebase Hydrate Form C in an amount sufficient to deliver 15 mg of the Compound 1 freebase equivalent.
In one embodiment, the pharmaceutical composition is a tablet dosage form. In one aspect, the tablet is coated with a pharmaceutically acceptable polymer.
In one embodiment, tablet is a controlled-release formulation, such as an extended release tablet dosage form (also referred to herein as a modified release or sustained release formulation). Such formulations permit the sustained release of the active ingredient over an extended period of time, as compared to immediate release solid dosage forms, which permit the release of most or all of the active ingredient over a short period of time (e.g., typically around 60 minutes or less). In one aspect, the tablet comprises an active ingredient and at least one additive selected from the group consisting of a release control polymer, a filler, a glidant, a lubricant (e.g., for use in compacting the granules), a pH modifier, a surfactant, and combinations thereof. In one aspect, the tablet comprises an active ingredient, a release control polymer, a filler, a glidant, and a lubricant. In one aspect, the tablet comprises an active ingredient, a release control polymer, a filler, a glidant, a lubricant, and a pH modifier.
In certain embodiments, the release control polymer will be a hydrophilic polymer. Examples of suitable release control polymers include, but are not limited to a cellulose derivative with a viscosity of between 1000 and 150,000 mPA-s, hydroxypropylmethyl cellulose (e.g., Hypromellose 2208 or controlled release grades of hydroxypropylmethyl cellulose, including the E, F, and K series), copolymers of acrylic acid crosslinked with a polyalkenyl polyether (e.g., Carbopol® polymers), hydroxypropyl cellulose, hydroxyethyl cellulose, non-ionic homopolymers of ethylene oxide (e.g., Polyox™), water soluble natural gums of polysaccharides (e.g., xanthan gum, alginate, locust bean gum, etc.), crosslinked starch, polyvinyl acetates, polyvinylpyrrolidone, mixtures of polyvinyl acetates and polyvinyl pyrrolidone, and combinations thereof. In one embodiment, the release control polymer is selected from the group consisting of hydroxypropylmethyl cellulose, copolymers of acrylic acid crosslinked with a polyalkenyl polyether (e.g., Carbopol® polymers), and combinations thereof. Examples of suitable fillers (“bulking agents”) include, but are not limited to, microcrystalline cellulose (e.g., Avicel© PH 101; Avicel® PH 102), mannitol (e.g., Pearlitol® 100 SD or Pearlitol® 200 SD), lactose, sucrose, sorbitol, and the like. In one embodiment, the filler is selected from the group consisting of microcrystalline cellulose, mannitol, and combinations thereof. Examples of suitable glidants include, but are not limited to, silicone dioxide (e.g., colloidal silicon dioxide), calcium silicate, magnesium silicate, talc, and combinations thereof. In one embodiment, the glidant is colloidal silicone dioxide. Examples of suitable lubricants include, but are not limited to, polyethylene glycol (e.g., having a molecular weight of from 1000 to 6000), magnesium stearate, calcium stearate, sodium stearyl fumarate, talc, and the like. In one embodiment, the lubricant is magnesium stearate. Examples of suitable pH modifiers include, but are not limited to, organic acids, such as tartaric acid, citric acid, succinic acid, fumaric acid; sodium citrate; magnesium or calcium carbonate or bicarbonate; and combinations thereof. In one embodiment, the pH modifier is tartaric acid. Examples of suitable surfactants include sodium lauryl sulfate.
In one embodiment, the pharmaceutical composition comprises from about 10 w/w % to about 35 w/w % of a pH modifier, and in particular, tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof. In other embodiments, the formulation comprises from about 20 w/w % to about 35 w/w %, or from about 20 w/w % to about 30 w/w %, or from about 20 w/w % to about 25 w/w %, or about 10 w/w %, about 15 w/w. %, about 20 w/w %, about 25 w/w % or about 30 w/w % pH modifier. In one embodiment, the pH modifier is tartaric acid.
As discussed herein, sustained peak plasma concentrations can theoretically be achieved by means of sustained release matrix systems. However, when such systems are made of hydrophilic polymers, such as HPMC, they seldom provide pH independent drug release of pH-dependent soluble drugs, and they are normally incapable of attaining zero-order release except for practically insoluble drugs. Unexpectedly, is has now been discovered that when a pH modifier, such as tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof, is used in a hydrophilic sustained release matrix system, it allows Compound 1 or a pharmaceutically acceptable salt or solid state form thereof to be released at a steady rate regardless of the pH of the environment. In an unexpected finding, it was discovered that as a tablet containing the hydrophilic polymer matrix system erodes, Compound 1 reacts with the HPMC, creating a thicker gel layer which slows the release of Compound 1 from the tablet. The resulting gel layer provides an environment suitable for Compound 1 to dissolve.
Thus, in one embodiment, the pharmaceutical composition of the present disclosure exhibits a pH-independent release of the active ingredient (Compound 1). Advantageously, it has been discovered that including organic acids, such as a tartaric acid, in the composition as a pH modifier improves the release profile, and results in a pH independent release of the active ingredient. Without wishing to be bound to any particular theory, it is believed that the pH modifier and hydrophilic polymer create a microenvironment in which the active ingredient dissolves, and then is released. The release from the microenvironment occurs at approximately the same rate, regardless of pH. This is particularly advantageous, since the pH of the gastrointestinal tract may vary significantly from the stomach (e.g., pH of about 1.5-3), to the duodenum (e.g., pH of about 4-5), to the lower part of the small intestines (e.g., pH of about 6.5-7.5).
Thus, in one embodiment, the pharmaceutical composition is an extended release formulation comprising Compound 1, or a pharmaceutically acceptable salt or solid state form thereof, a hydrophilic polymer, and a pH modifier, wherein the hydrophilic polymer, in contact with water, forms a gel layer that provides an environment suitable for Compound 1, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve. In some embodiments, the environment suitable for Compound 1, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve has a pH equal to or less than about 3.8 at 37° C. In some such embodiments, the environment has a pH of from about 1.5 to about 3.7, or from about 2.0 to about 3.7, or from about 2.5 to about 3.6, or from about 3.0 to about 3.6, or from about 3.0 to about 3.5.
In one such embodiment, the environment suitable for Compound 1, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve is as set forth above, and the extended release formulation comprises from about 10 w/w % to about 35 w/w % of a pH modifier, and in particular, tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof. In other embodiments, the formulation comprises from about 20 w/w % to about 35 w/w %, or from about 20 w/w % to about 30 w/w %, or from about 20 w/w % to about 25 w/w %, or about 10 w/w %, about 15 w/w %, about 20 w/w %, about 25 w/w % or about 30 w/w % pH modifier. In any of these embodiments, the pH modifier may be selected from the group consisting of tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, and combinations thereof. In one such embodiment, the pH modifier is selected from the group consisting of tartaric acid, fumaric acid, citric acid, succinic acid, and combinations thereof. In one such embodiment, the pH modifier is selected from the group consisting of tartaric acid and fumaric acid. In one embodiment, the pH motifier is tartaric acid. In one embodiment, the pH modifier is fumaric acid or citric acid. The weight % tartaric acid set forth herein is by weight of the uncoated composition (e.g., uncoated tablet). In any of the foregoing embodiments, the hydrophilic polymer may be a cellulose derivative with a viscosity of between 1000 and 150,000 mPA-s. In one embodiment, the hydrophilic polymer is selected from the group consisting of hydroxypropylmethyl cellulose, hydroxyethyl cellulose, and mixtures or combinations thereof. In one embodiment, the hydrophilic polymer is hydroxypropylmethyl cellulose. In one embodiment, the hydrophilic polymer is hydroxypropylmethyl cellulose Grade E, F, or K. In one embodiment, the hydrophilic polymer is Hypromellose 2208.
In one embodiment, the tablet is a compressed and/or milled tablet. For example, in some embodiments, the tablet is formed by blending the composition components (e.g., including the active ingredient and at least one pharmaceutically acceptable carrier). The composition can then be either directly compressed, or one or more of the composition components can be granulated prior to compression. In one embodiment, milling is performed using a mill fitted with any suitable size screen (e.g., a fitted with a screen size of from about 600 to about 1400 μm or about 610 μm or about 1397 μm). Compression can be done in a tablet press, such as in a steel die between two moving punches.
In other embodiments, the compressed and/or milled tablet is formulated using a wet granulation process. Use of wet granulation helps reduce and/or eliminate sticking that may occur when compression without wet granulation (e.g., direct compression) is used to formulate the tablets. In one embodiment, the wet granulation process may include the following steps: (a) combining the active ingredient (e.g., Compound 1 or a pharmaceutically acceptable salt thereof or a solid state form of Compound 1) and at least a portion of one additional composition component to form a dry granulation mixture; (b) contacting the dry granulation mixture with a granulation fluid to form a wet granulation mixture; (c) drying the wet granulation mixture to form a granulated material; (d) milling the granulated material to form a milled granulated material; (e) combining the milled granulation material with the remaining composition components; and (f) compressing the composition into the solid dosage unit (e.g., a tablet).
In step (a) of this process, the active ingredient may be combined with, for example, a portion of the release control polymer (e.g., HPMC), a portion of the filler (e.g., microcrystalline cellulose, such as Avicel® PH101), or both a portion of the release control polymer and a portion of the filler to form the dry granulation mixture. Any suitable porition of the release control polymer may be used in step (a). In one embodiment, th from about 5 to 10 wt. % or from about 6 to 8 wt. % of the total amount of the release control polymer in the composition is used in step (a).
In certain embodiments, the granulation fluid used in step (b) may comprise water, a suitable solvent (e.g., ethanol, isopropanol, etc.), or combinations thereof. In one embodiment, the granulation fluid comprises water. In one embodiment, the active ingredient may be combined with a portion of the filler, while a portion of the release control polymer (e.g., HPMC) is dissolved in a liquid, such as water, to form the granulation fluid. In one embodiment, the granulation fluid is sprayed on the dry granulation mixture.
The dried granulation material may be milled using, for example, a comill fit with any suitable screen size. In one embodiment, the screen size is from about 600 to about 900 microns, or from about 610 to about 813 microns. In one embodiment, the granulated material is milled using a comill fitted with a 610 μm screen. In one embodiment, the granulated material is milled using a comill fitted with a 813 μm screen.
In step (e), the milled granulation material is combined with any remaining composition components, such as any remaining filler (e.g., microcrystalline cellulose, such as Avicel® PH102), any remaining release control polymer, glidants, lubricants, pH modifiers, surfactants, and the like. In one embodiment, the filler and/or release control polymer included in the granulated material may be the same or different than the filler and/or release control polymer added in step (e). For instance, in one embodiment, the filler included in the granulated material (e.g., Avicel®PH101) may have a smaller particle size distribution than the filler added in step (e) (e.g., Avicel®PH102).
In one embodiment, the composition may be sieved, and the sieved composition blended, for example, after step (e), and prior to compressing the composition (step (f)). In one embodiment, the formulation is sieved prior to addition of any lubricant. In one embodiment, the pH modifier (e.g., tartaric acid) is optionally milled prior to combining with the granulated material.
In one embodiment, the present disclosure is directed to a process for preparing a pharmaceutical composition, the process comprising: (a) combining an active ingredient (e.g., Compound 1 or a pharmaceutically acceptable salt thereof or a solid state form of Compound 1) and at least a portion of one additional composition component to form a dry granulation mixture; (b) contacting the dry granulation mixture with a granulation fluid to form a wet granulation mixture; (c) drying the wet granulation mixture to form a granulated material; (d) milling the granulated material to form a milled granulated material; (e) combining the milled granulation material with the remaining composition components; and (f) compressing the composition to form the pharmaceutical composition.

The resulting mixture was quenched with HOAc (2.3 mL, 40 mmol) and warmed to 25° C. EtOH (40 mL) was added and the mixture seeded with the desired product (500 mg). After stirring an additional 2 hours, a mixture of EtOH (40 mL) and water (20 mL) was added over 8 hours. The product was then collected, washed with ethanol (2×40 mL) and dried to afford 10.7 g (88 wt % pure with 12% of the starting carbamate). A purified sample was prepared by recrystallizing from EtOAc.

The imidazolide from above was added and the resulting mixture was mixed at 25° C. while maintaining a pH of 9 by the portionwise addition of 10% KOH for 1 hour. Upon completion, the reaction was quenched with 20% aqueous citric acid (50 mL), stirred for 1 hour and the product extracted with EtOAc (2×50 mL). The combined organic layers were washed with 15% aqueous KH2PO4 (50 mL), saturated aqueous sodium bicarbonate (50 mL) and brine (25 mL). The solution of product was treated with active charcoal and concentrated by distillation. The residue was taken up in 2% water in EtOAc (70 mL), seeded and stirred 1 hour.

As an alternative to the Step F1 procedure, Compound 1 was prepared according to Step F2.
To a THF (500 mL) slurry of CDI (67.1 g, 414 mmol) was added dropwise 2,2,2-trifluoroethylamine (34.6 mL, 441 mmol) over 20 minutes while maintaining an internal temperature less than 30° C. The resulting solution was stirred for 1 hour.
To a biphasic mixture of 8-((3R,4S)-4-ethylpyrrolidin-3-yl)-3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazine bis hydrochloride (91.0 g, 276 mmol) and potassium phosphate dibasic (K2HPO4) (48.0 g, 276 mmol) in THF (500 mL) and water (500 mL) was added 20% KOH to adjust the pH to 9. The imidazolide from above was added and the resulting mixture was mixed at 25° C. while maintaining a pH of 9 by the portionwise addition of 20% KOH for 1 hour. Upon completion, the reaction was quenched with 50% aqueous citric acid (200 g), stirred for 1 hour and the product extracted with 2-MeTHF (2×500 mL). The combined organic layers were treated with 20% KOH at 50° C. for 30 min and after cooling to 25° C., the layers were separated, the organic layer was washed with 15% aqueous KH2PO4 (2×500 mL), and brine (250 mL). The solution of product was treated with active charcoal.
Following the carbon filtration of the solution containing 50 g of dissolved Compound 1 in Step F2 of Example 3, the solution was distilled to dryness. Two consecutive 250 mL portions of EtOAc were added and distilled to approximately 100 mL to bring the water content of the solution to below 1% w/w (as determined by coulometric Karl Fischer titration). This solution was adjusted to a total weight by adding 25% w/w EtOH 200 proof (75 g) and EtOAc (to give 500 g of solution). This solution was then treated with a 20 μm Teflon polish filter to remove residual salts from the reaction work-up. After filtration, the solution was again distilled to approximately 100 mL, followed by addition of 2 consecutive portions of 250 mL of EtOAc which were each distilled to a minimum volume (achieving a water content of not more than 0.05% w/w water and not more than 1% w/w EtOH after the final distillation). The final solution was adjusted to approximately 250 mL, and a sample was analyzed by HPLC to assay the concentration of Compound 1 (with a target concentration of not less than 18% w/w Compound 1).
Crystallization
The distillation product solution (250 g of total solution) was separated into two portions: 15% (37.5 g) and 85% (212.5 g) of the total volume. The 15% portion was added to the crystallization vessel and diluted with a premixed solution of EtOAc (353 g) and water (3.95 g) to achieve a final solution of approximately 1.9% w/w of Compound 1 and 1% w/w of water. This solution was allowed to recirculate from the crystallization vessel via a pump through an IKA wet mill (medium-fine-fine rotor-stator configuration) and returning into the top of the crystallization vessel. The wet mill was set to a rotor tip speed of 9 meters/sec and the crystallization solution was seeded with the desired crystal form, Freebase Hydrate Form C, of Compound 1. This crystal slurry was allowed to wet mill continuously for not less than 2 hours at a recirculation rate giving least 10 turnovers of the crystallization solution through the wet mill setup. Upon completion, the wet mill tip speed was reduced to 4 meters/sec, and the remaining 85% of the Compound 1 product solution was slowly added into the crystallization vessel over not less than 4 hours. After addition of the entire product solution, the antisolvent, n-heptane, was added slowly over not less than 4 hours to achieve approximately 30% w/w (260 g) of n-heptane in the final crystallization liquor (while maintaining a wet mill tip speed of 4 meters/second). Upon completion, wet milling was discontinued, the crystal slurry contents were recirculated into the crystallization vessel, and the crystal slurry was allowed to mix for not less than 1 hour.
Isolation and Drying
The crystal slurry was filtered under low pressure (approximately 10 psig of nitrogen) while collecting the mother liquor and continued until the resulting crystal cake was completely deliquored. A wash solution (69.4% w/w EtOAc, 30% w/w n-heptane, and 0.4% w/w water; 5 volumes of wash in total, 250 mL) was applied to the wet cake in two portions by deliquoring the cake completely after each portion. The wet cake was purged with a stream of nitrogen for not less than 3 hours, and then heated slowly (˜10° C./hour) to a target temperature of 50° C., not more than 55° C. and allowed to dry for not less than 12 hours. After 12 hours, a sample was taken to analyze the cake for residual ethyl acetate by gas chromatography and water content by Karl Fischer titration. The final dry product was analyzed further for product identity, impurity profiling, water content and Compound 1 potency.
In this example, Steps A-C of the Example 3 process were modified to eliminate certain work up steps and the isolation of the salt, and to improve purity of the bromomethyl ketone. Specifically, Compound 1 was prepared according to the following reaction scheme:
1-((benzyloxy)carbonyl)-4-ethyl-2,5-dihydro-1H-pyrrole-3-carboxylic acid (prepared as described in Example 1) (10 g, 36.3 mmol) and Ru(OAc)2—Segphos (0.030 g, 0.036 mmol) were charged to a 300 mL stirred SS Parr reactor, and were transferred to the controlled atmosphere glovebox. A solution of TEA (5.82 mL, 41.8 mmol) in MeOH (60 mL) was added, and then the reactor was closed and was removed from the glove box. The reactor was placed in a reactor station, and was purged first with inert gas and then pressurized with hydrogen (200 psig). The mixture was agitated and heated at 80° C. for 4 hours. The reaction was monitored by HPLC for conversion.
The reaction mixture was filtered through a polypropylene filter funnel with diatomaceous earth/polyethylene fritted disc (Chemglass part #OP-6603-12) to remove the catalyst, and MeOH (10 mL) was used as a rinse. The combined filtrate obtained was a light amber solution.
The combined filtrate from step 1 was concentrated in vacuo to approximately 20 mL. The concentrate was diluted with THF (10 g) and was concentrated in vacuo to approximately 20 mL. This was repeated four additional times. The concentrate was then diluted with THF (40 mL). To this solution was added CDI (8.62 g, 53.2 mmol) in portions over 30 minutes. The reaction was stirred at room temperature for 1 hour. The reaction was monitored by HPLC (derivatized with MeOH and DBU) for conversion.
A suspension of trimethylsulfoxonium chloride (9.29 g, 72.2 mmol) and KOtBu (7.18 g, 64.0 mmol) in THF (70 mL) was heated to 45° C. for 1 hour and then cooled −5° C. The (3S,4R)-benzyl 3-ethyl-4-(1H-imidazole-t-carbonyl)pyrrolidine-t-carboxylate solution (prepared above) was added dropwise over 1 hour while maintaining the internal temperature below −1° C. After the addition was complete, the reaction stirred for 1 hour at −5° C. The reaction was monitored by HPLC for conversion.
The slurry was adjusted to 0° C. and was quenched with water (16 mL). Then the mixture was concentrated in vacuo to approximately 170 mL. The concentrate was diluted with water (22 mL) and was concentrated in vacuo to approximately 170 mL. This was repeated five additional times. By the last concentration, the internal temperature was approximately 45° C. The solution was reduced to 5° C. over 6 hours. During this time the product precipitated. The slurry was held at 5° C. for 1 hour, and then the product was collected by vacuum filtration. The solid was washed with water (100 mL) and was dried in a vacuum oven at 45° C. for 24 hours. The dimethylsulfoxonium 2-((3R,4S)-1-benzyloxycarbonyl-4-ethylpyrrolidin-3-yl)-2-oxo-ethylide (9.62 g, 27.4 mmol) was isolated in 77% yield.

Dimethylsulfoxonium 2-((3R,4S)-1-benzyloxycarbonyl-4-ethylpyrrolidin-3-yl)-2-oxo-ethylide (10.0 g, 28.5 mmol, 1.0 equivalents), THF (100 mL), and 33% HBr in AcOH (8.37 g, 34.1 mmol, 1.2 equivalents) were charged sequentially and heated to 40° C. The reaction mixture was agitated for 5 hours, cooled to 20° C., and then distilled under vacuum to approximately 65 mL. EtOAc (20 mL) and heptane (50 mL) were charged, and the reaction mixture was washed with water (5×50 mL). The organic layer was concentrated under vacuum and chased with EtOAc (2×50 mL) concentrating to dryness each time. N,N-dimethylacetamide (20 mL) was then charged to provide 30.8 g of a 24.0 wt/wt % solution of (3R,4S)-benzyl 3-(2-bromoacetyl)-4-ethylpyrrolidine-1-carboxylate (73% yield). The solution was carried forward to the next step.
To a suspension of ethyl 5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-ylcarbamate (5.0 g, 13.9 mmol, 1.0 equivalents) and N,N-dimethylacetamide (20 mL) at 0° C. was charged a solution of LiOtBu (1.3 g, 16.0 mmol, 1.15 equivalents) and N,N-dimethylacetamide (10 mL) over 30 minutes. After agitating for 30 minutes, the reaction mixture was cooled to −10° C. A portion of the bromomethyl ketone solution (23.6 g, 24 wt/wt % in DMA, 16.0 mmol, 1.15 equivalents) from Step B above was then added over 1 hour. After the addition, the reaction mixture was agitated at −10° C. for 30 minutes, quenched with acetic acid (0.4 mL, 6.9 mmol, 0.5 equivalents), and warmed to 20° C. EtOH (40 mL) was then charged followed by seed (25 mg). The resulting slurry was aged at 20° C. for 1 hour, heated to 50° C. over 1 hour, and cooled to 20° C. over 3 hours. The heat cycling was performed 5 times total. After the heat cycling was complete, water (10 mL) was charged at 50° C. over 2 hours, and the slurry was cooled to 20° C. over 3 hours. The slurry was aged at 20° C. for 2 hours, filtered, and then washed with EtOH (2×25 mL). The isolated solids were dried under vacuum at 45° C. to deliver 7.4 g of (3S,4R)-benzyl 3-ethyl-4-(2-((ethoxycarbonyl)(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)amino)acetyl)pyrrolidine-1-carboxylate in 84% yield (99.6% purity).

Compound 1 may be prepared from the (3S,4R)-benzyl 3-ethyl-4-(2-((ethoxycarbonyl)(5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)amino)acetyl)pyrrolidine-1-carboxylate according to the procedure described in Steps D-F of Example 3, and Compound 1 may be isolated and crystallized according to the procedure described in Example 3G.
A. Method A: Precipitation from Water
Compound 1 (approximately 300 g) was dissolved in water (10 L) and 50% sodium hydroxide (160 g) was added drop-wise over a two hour period to adjust the pH to greater than 12. Solids formed immediately. The solids were filtered, washed with two 500 mL aliquots of water, and then dried in a vacuum oven. The solids were equilibrated for a short period of time at ambient temperature prior to characterization. Conversion to Amorphous Freebase of Compound 1 was confirmed by PXRD analysis.
B. Method B: Dehydration of Freebase Hydrate Form B
A sample of the Freebase Hydrate Form B form of Compound 1 (crystallized from ethanol/water at sub-ambient temperatures as described in Example 5, Method C below) was placed in a vacuum oven at 40° C. overnight. The solids removed from the vacuum oven were equilibrated for a short time at 23° C. prior to characterization. Conversion to Amorphous Freebase of Compound 1 was confirmed by PXRD analysis.
A. Method A: Freebase Solvate Form A (Isopropyl Acetate/Water Solvate)
A sample of the Amorphous Freebase of Compound 1 (25 mg) was added to a vial followed by isopropyl acetate (125 μL) and water (10 μL). All solids dissolved at ambient temperature. The solution was placed in a freezer at −16° C. for 4 days. The liquor was decanted and the crystallized solids were isolated. The isolated crystals were analyzed by PXRD while still wet. Conversion to Freebase Solvate Form A (isopropyl acetate/water solvate) of Compound 1 was confirmed by PXRD analysis.
B. Method B: Freebase Hydrate Form B from Methanol/Water
A sample of the Amorphous Freebase of Compound 1 (164 mg) and MeOH (621 mg) were added to a vial. The components were mixed at ambient temperature until the solids dissolved. Water (approximately 680 μL) was added to the vial and the vial was placed in an ice/sodium chloride bath at approximately −3° C. Crystal seeds comprising Freebase Hydrate Form B were added to the vial and the vial was placed in a freezer at −16° C. A sample was pulled from the crystallized suspension and the solids were immediately analyzed with PXRD and TGA-MS. Conversion to Freebase Hydrate Form B of Compound 1 was confirmed by PXRD and TGA-MS analysis.
C. Method C: Freebase Hydrate Form B from Ethanol/Water
A sample of the Amorphous Freebase of Compound 1 (4.2 g) was dissolved in EtOH (15.3g) in a jacketed reactor. Water (23.3 g) was slowly added to the reactor. The reactor solution was cooled to approximately 2° C. A small portion of a seed solution comprising the Freebase Hydrate Form B was charged to the reactor. The suspension was mixed at approximately 2° C. for 3 hours and water (36 g) in was charged to the reactor in small aliquots over several hours while maintaining the suspension at a temperature of approximately 2° C. The crystallized suspension was mixed at approximately 2° C. and the solids were isolated via filtration. Conversion to Freebase Hydrate Form B of Compound 1 was confirmed by PXRD analysis.
The Freebase Solvate Form A and Freebase Hydrate Form B do not readily crystallize from solution. In general, sub-ambient temperatures and sufficient water activity are needed to crystallize Freebase Solvate Form A and Freebase Hydrate Form B from solution.
Crystalline freebase hydrates and solvates have been isolated from several solvent systems either through primary nucleation (without seeding) or through seeding. In addition to crystallization from isopropyl acetate/water (as described in Method A above), crystalline freebase hydrates or solvates also have been isolated through primary nucleation (without seeding) from, e.g., n-butylamine/water and ethanol/water solvent systems. In addition to crystallization from methanol/water (as described in Method B above) and ethanol/water (as described in Method C above), crystalline freebase hydrates or solvates also have been isolated through seeding from, e.g., acetone/water; acetonitrile/water; ethyl formate/water; methyl acetate/water; ethyl acetate/water; methyl ethyl ketone/water; methyl isobutyl ketone/water, methyl isobutyl ketone/methyl tert-butyl ether/water; and isopropyl acetate/methyl tert-butyl ether/water solvent systems. The Freebase Solvate Form A (isopropyl acetate/water solvate) prepared in Method A above, the Freebase Hydrate Form B prepared in Methods B and C above, and these other crystalline freebase solvates or hydrates that have been prepared are isostructural and exhibit similar PXRD patterns. Notably, these crystalline freebase solvates and hydrates are distinguishable from and exhibit a different PXRD pattern than Freebase Hydrate Form C (a hemihydrate), which is described below.
The Freebase Solvate Form A and Freebase Hydrate Form B that were prepared were not stable after isolation at ambient conditions and readily dehydrated to the Amorphous Freebase.
A. Method A: Freebase Hydrate Form C from Ethanol/Water
A sample of the Amorphous Freebase of Compound 1 (2 g) was transferred to a 500 mL beaker equipped with a stirring bar. EtOH (50 g) was added to the beaker and stirred until all solids dissolved. The solution was transferred to a 250 mL jacketed flask equipped with a dispersing device. The solution was cooled to 6° C. Water (150 g) was added to the solution and the solution was subjected to high shear for two hours using the dispersing device. After solid formation was observed, an additional amount of water (50 g) was added to the resulting suspension. The suspension was held overnight at ambient temperature. Solids were isolated and examined on the following day. Conversion to Compound 1 Freebase Hydrate Form C was confirmed by PXRD analysis.
B. Method B: Freebase Hydrate Form C from Ethyl Acetate/Heptane/Water
A crude reaction mixture assaying for 11.1 g of Compound 1 was taken up in 2% water in EtOAc (70 g) and seeded with Freebase Hydrate Form C (100 mg). The suspension was stirred overnight and heptane (70 g) was added. The solids were collected by filtration, washed with water saturated EtOAc/heptane (1/1, 100 mL), and dried under vacuum at 50° C. Conversion to Compound 1 Freebase Hydrate Form C was confirmed by PXRD analysis.
As was observed with the Freebase Solvate Form A and the Freebase Hydrate Form B, the Freebase Hydrate Form C also does not readily crystallize from solution.
Three methods for the preparation of Compound 1 tartrate tetrahydrate (the “Tartrate Hydrate”) are described below. Method A describes an initial procedure that was used to prepare the tartrate tetrahydrate. Method B describes a modified procedure used to prepare the tartrate tetrahydrate at a larger scale. Method C describes a further modified procedure used to prepare the tartrate tetrahydrate. The modified procedure of Method C relative to the procedure of Method B further reduces solidification of the filter cake, a potential problem that potentially can impact manufacturability and downstream processing.
A. Method A
A sample of the Amorphous Freebase of Compound 1 (28.2 mg) was transferred to an amber vial. Water (200 μL) and L-tartaric acid (34.5 mg (approximately 3 equivalents)) were added to the vial. The suspension was vortexed under ambient conditions until all the solids dissolved. The solution in the vial was magnetically stirred at 0° C. The following day, the solids were isolated from the solution and left at ambient temperature for a short period of time prior to characterization. Conversion to the Compound 1 Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.
B. Method B
Compound 1 (4.6 g) was added to a jacketed reactor followed by the addition of isopropanol (6.5 mL) and IPAc (7.8 mL). The slurry was mixed at ambient condition until the solids dissolved. In a separate vial, L-tartaric acid (1.96 g) was dissolved in deionized water (3.92 mL). The L-tartaric acid solution was added to the reactor followed by the addition of tartrate tetrahydrate seed crystals (28 mg). The suspension was mixed for 30 minutes under ambient conditions. IPAc (71 mL) was added in small aliquots over 2 hours. The crystallized suspension was cooled to 5° C. and equilibrated at 5° C. overnight. The suspension was discharged onto a filter and the filter cake rinsed with 20 mL of water saturated IPAc. The filtered solids were air-dried for two days. Conversion to the Compound 1 Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.
C. Method C
Crystallization: Compound 1 (104 g) was added to a flask together with isopropanol (222.7 g) and IPAc (375.8 g). The components were mixed under ambient conditions until the solids dissolved. In a separate flask, L-tartaric acid (61.6 g) was dissolved in water (98.3 g). The contents of the two flasks were then added to a jacketed reactor. Tartrate tetrahydrate seed crystals (1.55 g) were added to the reactor solution. The resulting suspension was mixed overnight under ambient conditions. IPAc (2542 g) was charged to the reactor suspension over an 8 hour period.
Filtration. Washing and Drying: Approximately half of the crystallized tartrate suspension was charged to a jacketed agitated filter dryer. The suspension was cooled inside the filter dryer to approximately 11° C. The suspension was filtered using positive pressure until a wet cake was obtained. Water saturated IPAc (438 g) was charged to the filter dryer and the suspension was mixed overnight at approximately 11° C. The suspension was filtered using positive pressure until a wet cake was obtained. Water saturated MTBE (110 g) was charged to the filter dryer. After 10 minutes, the suspension was filtered with positive pressure until a wet cake was obtained. Water saturated MTBE (261 g) was charged to the filter dryer and the suspension was mixed at approximately 11° C. for 3.5 hours. The suspension was filtered with agitation using positive pressure until a wet cake was obtained. The wet cake was dried with constant agitation at a temperature of approximately 11° C. under humidified nitrogen and positive pressure for two days. Conversion to the Compound 1 Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.
Initial Preparation: A sample of the Amorphous Freebase of Compound 1 (23.8 mg), EtOAc (200 μL), and concentrated HCl (5 μL) were added to a vial. The viscous solution was warmed on a hot plate at 50° C. MeOH (20 μL) was added to the solution and stirring continued. EtOH (10 μL) was added and stirring continued at 50° C. The resulting solution was bi-phasic. The vial was placed in a bath at 0° C. while mixing with a magnetic stirrer continued. A white solid was obtained after approximately 1.5 hours.
Larger-Scale Preparation: The above-described procedure was repeated at larger scale to generate additional solids for characterization. A sample of the Amorphous Freebase of Compound 1 (50.3 mg), EtOAc (500 μL), and concentrated HCl (11 μL) were added to a vial. The solution was warmed on a hot plate and the same viscous phase as observed in the above-described procedure was obtained. EtOH (40 μL) was added to the solution and stirring continued. MeOH (40 μL) was added and the vial was placed in a bath at 0° C. while mixing with a magnetic stirrer continued. Once the solution was cooled, a drop of the seed slurry from the initial preparation was added. The suspension was mixed for 30 minutes in the cooling bath. The vial was placed in a freezer at −16° C. overnight. The solids in the vial were isolated via vacuum filtration. The filtered solids were equilibrated for a short period of time prior to characterization. Conversion to Compound 1 hydrochloride (Hydrochloride Solvate Form AA) was confirmed by PXRD analysis.
A sample of the Amorphous Freebase of Compound 1 (76 mg) and THF (approximately 228 μL) were added to a vial. The slurry was sonicated until a clear solution was obtained. Concentrated HCl (12 μL) was added to the clear solution. Some precipitation occurred immediately. The vial was placed in a freezer at −16° C. for 4 hours. More precipitation occurred. The solids were isolated from the vial after a few days and equilibrated for a short time at ambient prior to characterization. Conversion to Compound 1 hydrochloride (Hydrochloride Solvate Form BB) was confirmed by PXRD analysis.
A sample of the Amorphous Freebase of Compound 1 (50 mg) was dissolved in 0.2 mL of 50/50 v/v EtOAc/EtOH. Concentrated HCl (40 μL) and 0.8 mL of 50/50 v/v EtOAc/EtOH were added to the solution. EtOAc was slowly diffused via the gas phase into the product solution (i.e., vapor diffusion procedure). Solids were obtained after approximately three weeks. The solids were isolated via centrifugation filtration and equilibrated for a short time prior to characterization. Conversion to Compound 1 hydrochloride (Hydrochloride Solvate Form CC) was confirmed by PXRD analysis.
Compound 1 (78.5 mg), L-maleic acid (32 mg), and water saturated methyl isobutyl ketone (630 μL) were add to a vial. A thick slurry formed quickly after the addition of the solvents. Additional methyl isobutyl ketone was added and the suspension mixed over three days. The isolated wet solids were equilibrated for a short time prior to characterization. Conversion to the Compound 1 L-Maleate Form AAA was confirmed by PXRD analysis.
The L-Maleate Form BBB can be obtained by drying the L-Maleate Form AAA under vacuum. The L-Maleate Form BBB also can be obtained as described below.
Compound 1 (500 mg), L-maleic acid (150 mg), and water saturated methyl isobutyl ketone (4 mL) were add to a vial. The contents of the vial were mixed overnight. Approximately 10 mg of L-Maleate Form BBB crystal seeds were added to the vial. An additional 2 mL of water saturated methyl isobutyl ketone was added to the vial. The solids were isolated after crystallization and dried at 50° C./75% relative humidity. Conversion to the Compound 1 L-Maleate Form BBB was confirmed by PXRD analysis.
A sample of the Amorphous Freebase of Compound 1 was dissolved in water-free EtOAc at a concentration of 19.6% (w/w). An aliquot comprising approximately 1 mL was transferred to a 4 mL vial equipped with a magnetic stirrer. The vial was sealed with parafilm and mixed at 400 rpm on a magnetic stir plate at around 23° C. for almost 8 weeks. The resulting slurry was filtered and left at ambient conditions for a short period of time prior to characterization. Conversion to Freebase Anhydrate Form D was confirmed by PXRD analysis.
The solid state forms of Compound 1 were evaluated by microscopy. Samples were examined by microscopic visual examination using a polarizing microscope (model Eclipse E-600 POL, Nikon Corp., Garden City, NY). A color video camera was used to record digital images (model DXC 390, Fryer Co., Inc., Huntley, IL). Images were captured using MetaMorph Imaging System (version 4.6R8, Universal Imaging Corporation, Downingtown, PA). Observations regarding the crystal morphology of the samples are reported in Table 15-A below. Those of skill in the art will recognize that variation in crystal shape and size may be observed depending upon the specific crystallization conditions employed. The solvation states and PXRD profiles reported in Table 15-A correspond to the information presented in the figures and subsequent examples of this application.
The solid state forms of Compound 1 listed in Table 15-A were analyzed by X-ray powder diffraction (“PXRD”). The PXRD data were collected with a G3000 diffractometer (Inel Corp., Artenay, France) equipped with a curved position sensitive detector and parallel beam optics. The diffractometer was operated with a copper anode tube (1.5 kW fine focus) at 40 kV and 30 mA. An incident beam germanium monochromator provided monochromatic Kα1 radiation λ=1.540562 Å). The diffractometer was calibrated using the attenuated direct beam at one-degree intervals. Calibration was checked using a silicon powder line position reference standard (NIST 640c). Samples were prepared by spreading the sample powder in a thin layer on an aluminum sample holder and gently leveling with a glass microscope slide. The instrument was computer controlled using the Symphonix software (Inel Corp., Artenay, France) and the data was analyzed using the Jade software (version 6.5, Materials Data, Inc., Livermore, CA). The aluminum sample holder was mounted on the rotating sample holder of the G3000 diffractometer and the diffraction data collected at ambient conditions.
Tables 16-A through 16-J set out the significant parameters of the main peaks in terms of 20 values and intensities for the crystalline forms analyzed. It is known in the art that an X-ray powder diffraction pattern may be obtained which has one or more measurement errors depending on measurement conditions (such as equipment, sample preparation or machine used). In particular, it is generally known that intensities in an X-ray powder diffraction pattern may fluctuate depending on measurement conditions and sample preparation. For example, persons skilled in the art of X-ray powder diffraction will realize that the relative intensities of peaks may vary according to the orientation of the sample under testing and on the type and setting of the instrument used. The skilled person also will realize that the position of reflections can be affected by the precise height at which the sample sits in the diffractometer and the zero calibration of the diffractometer. The surface planarity of the sample also may have an effect on the results. A person skilled in the art will appreciate that the diffraction pattern data presented below is not to be construed as absolute and any crystalline form that provides a power diffraction pattern substantially identical to those disclosed below fall within the scope of the present disclosure (for further information see Jenkins, R & Snyder, R. L. ‘Introduction to X-Ray Powder Diffractometry’, John Wiley & Sons, 1996).

Unit cell parameters were determined for the Freebase Hydrate Form C based on a single crystal X-ray diffraction study and are reported below in Table 17-A. The single crystal X-ray diffraction data were collected using a Bruker Apex II diffractometer (Bruker AXS, Madison, W1) equipped with an Apex II CCD area detector. The diffractometer was operated with a molybdenum anode tube (2.0 kW fine focus) at 50 kV and 40 mA. An incident beam silicon monochrometer provided Mo-Kα1 monochromatic radiation. The data were collected under a stream of cold nitrogen gas at 100 K using a Kryoflex low temperature device (Bruker AXS, Madison, WI). The beam diameter for data collection was 5 mm and the detector distance was 6 cm. The alignment of the goniometer was checked using a spherical 2-Dimethylsufuranylidene-1,3-indanedione (YLID) crystal. The instrument was computer controlled using the BIS and Apex 2 software programs (Bruker AXS, Madison, W1). The data were analyzed using Apex 2 software (Version 2011.2-0, Bruker AXS, Madison, W1).
Unit cell parameters also were determined for the Tartrate Hydrate based on data from a PXRD study and are reported below in Table 17-B. The unit cell parameters for the Tartrate Hydrate, however, have not been confirmed in a single crystal X-ray diffraction study. The asymmetric unit contains one molecule of Compound 1, one molecule of L-tartaric acid, and 4 molecules of water.
Unit cell parameters also were determined for the Freebase Anhydrate Form D based on a single crystal X-ray diffraction study, performed using the method as described above for Freebase Hydrate Form C, and are reported below in Table 17-C.
The solid state forms of Compound 1 listed in Table 15-A were analyzed in a thermogravimetric analysis (“TGA”) study. TGA thermograms were collected with a Mettler TGA/sDTA 851e (Mettler-Toledo International Incorporated, Scwezenbach, Switzerland) equipped with a TSO801RO robotic autosampler. The instrument was operated and data evaluated with the Stare software (V9.01, Mettler-Toledo International Incorporated, Scwezenbach, Switzerland). The temperature axis was calibrated with indium and aluminum standards. The sample powders were encapsulated in an appropriate pan and scanned at certain rate as specified in TGA thermogram plots. A 50 mL/minute nitrogen purge to the sample chamber was used. In cases where TGA was run with TA instruments, data were collected on a thermal balance (Q-500 or Q-5000, TA Instruments, New Castle, DE) equipped with a data analyzer (Universal Analysis 2000, version 4.5A, TA Instruments, New Castle, DE). During experiments, the furnace was purged with nitrogen at 60 mL/minute, while the balance chamber was purged at 40 mL/minute. Temperature of the TGA furnace was calibrated using curie points of aluminum and nickel. Sample size ranged from 2 mg to 20 mg, and a heating rate of 10° C./minute was used.
For TGA-MS, the thermogravimetric analysis part was the same as above. The mass of evolved gas was analyzed with PFEIFFER GSD 301 T3 ThermoStar (PFEIFFER Vacuum, Asslar, Germany). The instrument was operated and data evaluated with Software Quadstar 32-bit (V7.01, Inficon, LI-9496 Balzers, Liechtenstein).
For thermogravimetric analyses that were performed on Mettler TGA/sDTA 851e (Mettler-Toledo International Incorporated, Scwezenbach, Switzerland), simultaneous Differential Thermal Analysis (sDTA) signals were also recorded and the data were analyzed with the Stare software (V9.01, Mettler-Toledo International Incorporated, Scwezenbach, Switzerland).

As with all thermal analysis, one of skill in the art will appreciate that the DSC thermogram may change to some extent depending on factors such as heating rate, sample particle size, sample purity, sample moisture content, ambient relative humidity, etc.
The solid state forms of Compound 1 listed in Table 15-A were analyzed in a moisture vapor isotherm study. Moisture vapor isotherm data were collected with a DVS Advantage (Surface Measurement Systems Ltd, Alperton, United Kingdom). The sample powder (5 mg to 20 mg) was loaded on a tared pan of the DVS Advantage. The moisture sorption isotherm data were collected from 30-0-90-0-30% relative humidity in 10% relative humidity intervals. For each step, the dm/dt criteria was 0.001% over 5 minutes, a minimum dm/dt time of 30 minutes, and a maximum dm/dt of 120 minutes. Data was collected isothermally at 25° C. with a nitrogen flow rate of 200 cm3/minute. The post DVS sample was kept at approximately 30% relative humidity before PXRD analysis.

The solid state forms of Compound 1 listed in Table 15-A were analyzed in a solid state accelerated stability study. Samples (approximately 1 mg to 2 mg) of the solid state form were weighed into glass vials and tested as described below. Chemical stability was acceptable for the Amorphous Freebase, the Freebase Hydrate Form C, and the Tartrate Hydrate. The L-maleate salt, however, was prone to chemical degradation.

L-Maleate Form BBB: When stored at 50° C./75% relative humidity (open and closed glass vials), the L-maleate salt degraded to products that were not observed for the Freebase Hydrate Form C or the Tartrate Hydrate.
The solid state forms of Compound 1 listed in Table 15-A were analyzed in a thermal degradation study. The following pH solutions were prepared: 0.1N hydrochloric acid (HCl); 50 mM sodium phosphate buffer (pH 7.4, adjusted to 0.155 M ionic strength with sodium chloride) and FasSIF (pH 6.5). For each buffer, a target concentration of about 100 gg/mL was prepared by accurately weighing about 1 mg of the solid state form using a microanalytical balance into a scintillation vial. Water (1 mL) was added to dissolve the solid as a stock solution. The stock solution was diluted 10 times in the various buffers to prepare reaction solutions. The peak area of the compound in these reaction solutions was monitored at 37° C. by HPLC every two hours up to 32 hours total.
For equilibrium solubility, sufficient solid was added to 3-4 mL liquid medium in triplicate, such that excess solid remained undissolved. The mixtures were equilibrated for 24-48 hr at 25 rpm on an end-over-end tumbler model 30-1200 (Vankel, Cary, NC) in a constant temperature water bath. After equilibration, the mixtures were inspected to assure that the amount of excess solid was sufficient to permit re-characterization. If not, additional solid was added and the mixtures were again equilibrated for 24-48 hr. The pH of aqueous suspensions was determined after equilibration. The solid phase was separated from the liquid phase by centrifugation at 3300 rpm at equilibration temperatures (i.e., 25° C. or 37° C.). The supernatant was then filtered (13 mm Acrodisc® syringe filter with 0.45μ GHP membrane, Pall® Life Sciences, Ann Arbor, MI) to discard the initial 2 mL (to saturate filter) and capture the last 1 mL for analysis. The filtrate was diluted as needed for quantification of the material studied by HPLC method (as detailed elsewhere herein). The physical form of the recovered solid was characterized by powder X-ray diffraction to examine whether or not phase change had occurred

The paddles of the dissolution apparatus were operated at 75 RPM, with 1.5 mL samples from the dissolution vessel automatically obtained at the designated time periods. The sample filtrate was the sample preparation.
For the analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % of the labelled amount of active released (% LA Released) was calculated. The results are set forth in

The formulation was prepared by first milling the tartaric acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The Freebase Hydrate Form C, microcrystalline cellulose, mannitol, milled tartaric acid, release control polymer, and colloidal silicone dioxide were combined and blended. The blend was milled using a Mobil Mill fitted with a 610 micron screen. The magnesium stearate was screened through mesh #30 and was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press.
The tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.4 mg of coating had been applied to the tablets.
The Freebase Hydrate Form C solid state form of Compound 1 listed in Table 15-A was formulated into 15 mg or 30 mg extended release tablets according to the formulations set forth in Table 37-A. The tablets were prepared using a wet granulation process, and were compressed into tablets having a core weight of about 480 mg.
aProvides 30 mg of Compound 1 freebase equivalent.
bProvides 15 mg of Compound 1 freebase equivalent.
cFilm coat weight is approximate.
The formulation was prepared by first milling the tartaric acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The intragranular portion of the hydroxypropylmethyl cellulose release control polymer, the Freebase Hydrate Form C, and intragranular portion of the microcrystalline cellulose filler were added to a granulator, and mixed. Water was sprayed to granulate. The granulated material was then dried and milled using a comill fitted with a 610 micron screen. The milled granulation was then added to the extragranular tablet components other than magnesium stearate, and sieved using a comill fitted with a 1397 micron screen, followed by blending. The magnesium stearate was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press.
The tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.4 mg of coating had been applied to the tablets.
In this example, the effect of various organic acid pH modifiers (e.g., tartaric acid, citric acid, succinic acid, and fumaric acid) on the release rate of Freebase Hydrate Form C from 24 mg once-daily extended release (ER) tablets was evaluated. Freebase Hydrate Form C was formulated into 24 mg extended release tablets according to the formulations set forth in Table 43-A.
The formulations were prepared by first milling the organic acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The active, microcrystalline cellulose, milled organic acid, and release control polymer, were combined and blended. The blend was milled using a Mobil Mill fitted with a 610 micron screen. The magnesium stearate was screened through mesh #30 and was added to the bin and blended. The lubricated granulation was compressed into 480 mg weight tablets using a rotary tablet press.
The effect of the organic acids on the dissolution profile of the tablets was evaluated at pH 1.2 and pH 6.8. The dissolution tests were carried out using the dissolution parameters and conditions as described above in Examples 26 and 27 and 32-35. For analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % of the labelled amount of active released (% LA Released) was calculated. The results are set forth in
As can be seen from these results, organic acids improved dissolution rate at high pH, with tartaric acid showing the best improvement. The formulations comprising the control release polymer Carbopol® with tartaric acid provided near linear release at pH 6.8.
To measure the pH of the environment created when Compound 1 reacts with HPMC, the following experiment was performed.
The Freebase Hydrate Form C solid state form of Compound 1 was formulated into 30 mg extended release tablets according to the formulations set forth in Table 44-A. The tablets were prepared using a wet granulation process, as described in Examples 37-42.
Dissolution media of 0.01 N HCl (pH 2) and 113 mM sodium phosphate buffer (pH 6.8) was prepared at 37° C. One tablet was added to 500 mL of 0.01 N HCl media and stirred at 75 rpm at 37° C. for one hour in a Vankel VK 7010 dissolution bath. Then 400 mL of sodium phosphate buffer was added. The solution was stirred an additional three hours. The tablet was removed, rinsed with water and dried using laboratory tissues. The gel that formed on the tablet was separated from the dry core for pH measurement. This procedure was repeated three times for each formulation. The pH of the gel formed on the tablets is set forth in Table 44-B. The pH results are plotted in
The pharmacokinetic profile of the 15 mg once-daily extended release (ER) tablets prepared in Example 28 was evaluated, and compared to that of a 12 mg immediate-release (IR) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects (n=11) were administered a single dose of the 12 mg IR capsule (Regimen A) and the 15 mg ER (once-daily) tablet from Example 28 (Regimen B) under fasting conditions in a randomized, two-period, cross-over study design. Subjects were administered Regimen A in the first study period and Regimen B in the second study period, or administered Regimen B in the first study period and Regimen A in the second study period. Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen B) relative to the IR capsule formulation (Regimen A) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 45-B below.
For Regimen B versus Regimen A, the point estimates for the ratios of AUCt and AUCinf were near unity, and the 90% confidence intervals were within the 0.86-1.09 range.
The pharmacokinetic profile of the 30 mg once daily extended release (ER) tablets prepared in Example 31 was evaluated, and compared to that of a 24 mg dose of an immediate release (IR) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects (n=12) were administered a single 24 mg dose (two 12 mg IR capsules) (Regimen C) and the 30 mg ER (once daily) tablet from Example 31 (Regimen D) under fasting conditions in a randomized, two-period, cross-over study design. Half the subjects were administered Regimen C in the first study period and Regimen D in the second study period, while the other half were administered Regimen D in the first study period and Regimen C in the second study period. Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

As can be seen from this data, the 30 mg ER tablet provided a lower Cmax and comparable AUC to the 24 mg dose IR capsule (2×12 mg) under fasting conditions.
The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen D) relative to the IR capsule formulations (Regimen C) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 46-B below.
For Regimen D versus Regimen C, the point estimates for the ratios of AUCt and AUCinf were near unity, and the 90% confidence intervals were within the 0.82-1.03 range.
The pharmacokinetic profile of the 30 mg extended release tablets prepared in Example 31 after a high-fat meal was evaluated, and compared to the pharmacokinetic profile of the 30 mg extended release tablets under fasting conditions (see Example 46).
Following completion of the Example 46 study, the healthy human subjects (n=12) were administered single doses of the 30 mg ER (once daily) tablet from Example 31 after a high-fat meal (Regimen E). Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures.
Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter, and compared to the pharmacokinetic parameters for the 30 mg tablets administered under fasting conditions (see Example 46, Regimen D). The results are summarized in Table 47-A. The mean concentration of Compound 1 at each time point using linear (

The relative bioavailability for a single dose of the once-daily (ER) 30 mg tablet formulation after a high-fat meal (Regimen E) relative to the bioavailability of the ER 30 mg tablet under fasting conditions (Regimen D) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 47-B below.
As can be seen from Tables 47-A and 47-B, there is no clinically meaningful food effect for the 30 mg ER tablets. Administration following a high-fat meal increased the Compound 1 mean AUC and Cmax by 17% and 20%, respectively.
The steady state pharmacokinetic profile of the 15 mg once daily extended release (ER) tablets (prepared in Example 28) and the 30 mg once daily ER tablets (prepared in Example 31) was evaluated.
Healthy human subjects (n=24) were assigned to one of two regimens. Subjects in Regimen F (n=12) were administered the 15 mg ER tablet from Example 28 once daily for seven days under non-fasting conditions. Subjects in Regimen G (n=12) were administered the 30 mg ER tablet from Example 31 once daily for seven days under non-fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

As can be seen from this data, the observed steady state Cmax and AUC24 following 15 mg QD and 30 mg QD administration are generally consistent with the single dose and food-effect results obtained in Examples 45-47. The bioavailability of the 15 mg and 30 mg ER tablets is 70% to 80% relative to the same dose of IR capsules.
The steady state pharmacokinetic profile of the 15 mg once daily extended release (ER) tablets (prepared in Example 28) under fasting conditions was evaluated, and compared to that of a 6 mg immediate release (IR) twice daily (BID) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen K (n=12 at onset; n=11 on Day 7) were administered the 6 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen L (n=12) were administered the 15 mg ER tablet from Example 28 once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The relative bioavailability for the once-daily (ER) tablet formulation (Regimen L) relative to the twice daily (IR) capsule formulation (Regimen K) at steady state was also determined based on analysis of the natural logarithms of Cmax, AUC24, Cmin, and C24. The results are summarized in Table 49-B below.
The ratio of steady-state AUC for the 15 mg QD tablets relative to the 6 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The ratio of the steady-state Cmin was approximately 1 for the 15 mg QD tablet relative to the 6 mg BID capsules.
The pre-morning dose trough concentration (Ctrough) for the 6 mg BID capsules and 15 mg QD tablets was determined prior to the morning dose on Days 2-8. The results are set forth in
As can be seen from this data, at steady state under fasting conditions, the 15 mg QD tablets provided equivalent AUC24 and comparable Cmax and Cmin relative to the 6 mg BID capsules. The steady state Cmax was 10% lower for the 15 mg QD tablet compared to the 6 mg BID capsule.
The steady state pharmacokinetic profile of the 30 mg once daily extended release (ER) tablets (prepared in Example 31) under fasting conditions was evaluated, and compared to that of a 12 mg immediate release (IR) twice daily (BID) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen M (n=11) were administered the 12 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen N (n=12 at onset; n=11 at Day 7) were administered the 30 mg ER tablet from Example 31 once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen N) relative to the twice daily (IR) capsule formulation (Regimen M) was also determined based on analysis of the natural logarithms of Cmax, AUC24, Cmin, and C24. The results are summarized in Table 50-B below.
The ratio of steady-state AUC for the 30 mg QD tablets relative to the 12 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The steady-state Cmin for the 30 mg QD tablet was approximately 13% lower than for the 12 mg BID capsules. Outliers with high Cmin in the 12 mg BID dose may have contributed to this difference.
The pre-morning dose trough concentration (Ctrough) for the 12 mg BID capsules and 30 mg QD tablets was determined prior to the morning dose on Days 2-8. The results are set forth in
The pharmacokinetic profile of the 6 mg immediate release (IR) twice daily (BID) capsules and the 12 mg IR twice daily capsules was determined on Day 7 of Regimen K (Example 49) and Regimen M (Example 50), respectively, after administration of the morning (AM dose) and evening (PM dose).

The effect of a high-fat meal on the Example 37, 38, and 39 formulations was also evaluated.
Healthy human subjects (n=36) were administered a single dose of the 30 mg ER (once daily) tablet from Example 31 (ER8), Example 37 (ER10), Example 38 (ER11), and Example 39 (ER12) under fasting conditions or after a high-fat meal (non-fasting), in an open-label, randomized, four-period, incomplete crossover study. Doses in the four periods were seprated by at least four days. Dosing regimens were as set forth below in Table 52-A.
Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 1 hour after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

Compound 1 has been studied in 2 Phase 1 studies, first in human single ascending dose study (Study Ml3-401, described in WO 2015/061665, and referred to herein as Study 1), and then in a multiple ascending dose study (Study Ml3-845, also generally referred to in WO 2015/061665, and referred to herein as Study 2).
In Study 1, a total of 42 healthy volunteers received a single dose of Compound 1. In Study 2, a total of 32 healthy volunteers received multiple doses of Compound 1 for 14 days (Study 2, Part 1). In addition, 14 patients with RA were enrolled and completed the double-blind Part 2 of Study 2. The study was designed as a multiple-dose, randomized, multicenter trial, with the primary objective as assessing the safety, tolerability, and PK of multiple ascending doses of Compound 1 in healthy adult volunteers and to assess the safety, tolerability, and PK of multiple doses of Compound 1 in patients with RA who are on a stable methotrexate regimen.
Details of Study 1 and Study 2 and results obtained therefrom are provided below.
Study 1—Single-Dose Escalation in Healthy Subjects
Study 1 was a single-dose escalation evaluation of Compound 1. Study 1 was designed as a single-site, randomized, double-blind, placebo-controlled study. Fifty-six subjects in general good health were randomized to receive single doses of Compound 1 immediate release capsules comprising Tartrate Hydrate (1, 3, 6, 12, 24, 36, and 48 mg) or placebo in a 3:1 ratio with 8 subjects in each dose level. Study drug was administered following at least 10 hours of fasting. The study was conducted at PPD Development (Austin, TX). Subjects were confined to the study site and supervised for approximately 8 consecutive days. Study protocol and informed consent were approved by RCRC institutional review board (IRB) (Austin, TX).
Study 2—Multiple-Dose Escalation
In Study 2, multiple twice-daily (BID) doses of immediate release capsules comprising Tartrate Hydrate were administered to healthy subjects (Part 1) or to subjects with rheumatoid arthritis (RA) receiving stable doses of methotrexate (Part 2). Both evaluations followed randomized, double-blind, placebo-controlled designs. Part 1 was conducted at PPD Development (Austin, TX) and Part 2 was conducted at two sites: Aspen Clinical Research (Orem, UT) and Altoona Center for Clinical Research (Duncansville, PA). Study protocol and informed consents were approved by RCRC IRB (Austin, TX) and Quorum Review IRB (Seattle, WA).
Study 2-Part 1—Multiple-Dose Escalation in Healthy Subjects
The objective of Part 1 of the multiple-dose study was to characterize the pharmacokinetics, safety, and tolerability of multiple oral doses of Compound 1 immediate release capsules comprising Tartrate Hydrate in healthy subjects. Four escalating dosing regimens (3, 6, 12, and 24 mg Compound 1 or matching placebo twice daily for 13 consecutive days and once in the morning on Day 14) were evaluated. Study drug was administered approximately 30 minutes after a standard breakfast (in the morning) or a snack (in the evening). Forty-four healthy subjects participated in this part of the study with 11 subjects per dose group (8:3 Compound 1: placebo ratio). Subjects were confined to the study site and supervised for approximately 18 days.
Study 2-Part 2—Multiple-Dose Evaluation in Subjects with RA
The objective of Part 2 of the multiple dose study was to assess the pharmacokinetics, safety, and tolerability of multiple oral doses of Compound 1 immediate release capsules comprising Tartrate Hydrate in subjects with mild to moderate RA who were on stable methotrexate treatment. This evaluation was designed to enroll approximately 32 subjects randomized in a 1:1:1:1 ratio to one of four parallel twice-daily regimens (6, 12, and 24 mg Compound 1 and placebo). Subjects received study drug for 26 consecutive days (Study Days 3 through 28) and a single morning dose of study drug on Study Day 29. Compound 1 was administered following breakfast for the morning dose and dinner or snack for the evening dose. Subjects were on methotrexate therapy for at least 3 months and on a stable dose of 10 to 25 mg/week of methotrexate for at least 4 weeks prior to the first dose of study drug administered on Study Day 3 and continued their weekly stable dose of methotrexate on Study Days 1, 8, 15, 22 and 29. Subjects were confined to the study site for a total of 10 days—from Day 1 to Day 4 and from Day 27 to Day 31.
Study Participants
Subjects underwent screening procedures within 30 days prior to the initial administration of study drug. Subjects signed a written informed consent prior to the initiation of any screening or study-specific procedures. Subjects were eligible for study participation if they were men or women between 18 and 55 years of age (Study 1 and Study 2—Part 1) or 18 to 75 years of age (Study 2—Part 2); judged to be in good general health based upon the results of medical history, laboratory profile, physical examination, chest x-ray, and 12-lead electrocardiogram (ECG); and their body mass index (BMI) was within 19 to 29 kg/m2 (Study 1 and Study 2-Part 1) or within 19 to 39 kg/m2 (Study 2—Part 2) at screening. Subjects were considered eligible to participate in Study 2—Part 2 if they had diagnosis of RA based on the 2010 American College of Rheumatology/European League against Rheumatism criteria 6 months, have been on methotrexate therapy ? 3 months (and folate or equivalent for at least 2 weeks prior to Study Day 1), on a stable methotrexate dose of 10 to 25 mg/week for at least 4 weeks prior to the first dose of study drug administered on Study Day 3.
In both studies, subjects were excluded if they had any clinically significant abnormalities, infection, major febrile illness, hospitalization, or had any clinically relevant surgical procedure within 30 days prior to the first dose of study drug; had positive test result for hepatitis A virus immunoglobulin M, hepatitis B surface antigen, or hepatitis C virus antibody, or HIV antibodies at Screening; had history or evidence of active or latent tuberculosis; had history of diabetes or lymphoproliferative disease or evidence of immunosuppression (except for use of methotrexate in Study 2—Part 2); or had clinically significant findings at Screening as determined by the principal investigator. Additionally, subjects in Study 2—Part 2 were excluded if they had a history of acute inflammatory joint disease of different origin other than RA or had current or expected need for oral intake of >10 mg prednisone/day or equivalent corticosteroid therapy.
Pharmacokinetic Sampling
In healthy subjects, serial blood samples were collected over 72 hours after single dosing (Study 1) or over 12 hours after the first dose (Study Day 1) and over 72 hours after the last dose (Study Day 14) of study drug (Study 2-Part 1). In subjects with RA, serial blood samples were collected over 48 hours on Study Day 1 for methotrexate assay, over 12 hours following the first Study drug dose on Study Day 3 for Compound 1 assay, over 12 hours following the morning Study drug dose on Study Day 28 for Compound 1 assay, and over 48 hours following the last Study drug dose on Study Day 29 for Compound 1 and methotrexate assays. Pre-dose trough samples were collected prior to the morning dose on Study Days 5, 6, 7, 13, and 14 in Study 2—Part 1 to assess attainment of steady state.
Urine for Compound 1 assay was collected over a 12-hour interval after the last dose was administered on Study Day 14 in Study 2—Part 1 and on Study Days 28 and 29 in Study 2—Part 2. Urine for methotrexate assay was collected for 48 hours on Study Day 1 and Study Day 29.
Plasma and urine concentrations of Compound 1 and methotrexate were determined using validated liquid chromatography method with mass spectrometric detection methods. The lower limits of quantitation (LLOQ) for Compound 1 and methotrexate in plasma were established at 0.0503 ng/mL and 1.00 ng/mL, respectively. The LLOQ for Compound 1 and methotrexate in urine were established at 1.01 ng/mL and 0.0500 gg/mL, respectively. Samples quantified below the LLOQ were reported as zero. For Compound 1 assays, inter-run variability (measured as % coefficient of variation [% CV]) was ≤9.5% for plasma ≤8.4% for urine and the mean absolute bias was ≤6.7% for plasma and ≤5.9% for urine. For methotrexate assay, inter-run variability (% CV) was ≤3.9% for plasma and ≤5.2% for urine and the mean absolute bias was ≤5.4% in plasma and ≤13.1% in urine.
Pharmacokinetic Analyses
Compound 1 and methotrexate pharmacokinetic parameters were determined using non-compartmental analyses with Phoenix software (Version 6.3, Certara, Princeton, NJ, USA). Calculated pharmacokinetic parameters included the maximum observed plasma concentration (Cmax), time to Cmax (Tmax), trough plasma concentration (Ctrough), the apparent terminal phase elimination rate constant (β), the terminal phase elimination half-life (t1/2), the area under the plasma concentration-time curve (AUC) [from time 0 to time of the last measurable concentration (AUCt), from time 0 to infinity (AUC∞) for single dosing, and over a 12-hour dosing interval (AUC0-12, or AUC12,ss) for multiple dosing and the apparent oral clearance (CL/F). Compound 1 functional half-life (t1/2F) following multiple dosing was calculated as ln(2)/(ln[Cmax/Ctrough]/τ) at steady state, where r is the 12 hour dosing interval (Dutta et al., Clin. Drug Investig., 2006, Vol. 26(12), pp. 681-690). The accumulation ratio (Rac) was calculated as the ratio of Compound 1 AUC0-12 on Day 14 to Day 1 (Study 2—Part 1) or Day 28 to Day 3 (Study 2—Part 2). The percentage of Compound 1 dose recovered unchanged in urine (fe %) at steady state was calculated as the amount of Compound 1 recovered in urine over the 0 to 12 hour interval (Au,0-12), divided by the administered dose and multiplied by 100. Renal clearance (CLr) was calculated as Au,0-12/AUC0-12 at steady state. Methotrexate fe % was calculated as the amount of methotrexate recovered in urine over the 0 to 48 hour interval (Au,0-48), divided by the administered dose and multiplied by 100. CLr of methotrexate was calculated as Au,0-48/AUC0-48. The effect of co-administration of methotrexate on Compound 1 exposure was assessed from the ratios of Compound 1 AUC0-12 and Cmax on Study Day 29 to Study Day 28. The effect of Compound 1 on methotrexate exposure was assessed from the ratios of methotrexate AUC∞ and Cmax on Study Day 29 to Study Day 1.
Safety and Tolerability Assessment
Safety was evaluated based on assessments of adverse events, vital signs, physical examination, laboratory metrics, and 12-lead electrocardiogram (ECG). All subjects who received at least one dose of study drug were included in the safety analyses. Subjects who were administered placebo were pooled into a single group within each study or study part. Laboratory test values and vital signs measurements that were above or below the reference range were identified. Subjects were followed-up for a total of 7 days in Study 1, 35 days in Study 2—Part 1, and 57 days in Study 2—Part 2. In healthy subjects, clinical adverse events were graded as described in the Guidance for Industry Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (September 2007). In subjects with RA, the severity of adverse events were rated by the investigator as mild (transient and easily tolerated by the subject), moderate (causes subject discomfort and interrupts the subject's usual activities), or severe (causes considerable interference with the subject's usual activities and may be incapacitating or life-threatening). One subject in Study 2—Part 2 was randomized to the placebo arm, but received Compound 1 in error on Study Days 10 to 16. Therefore, this subject was included with the Compound 1 cohort for safety assessments
Statistical Analyses
Dose proportionality for Compound 1 in healthy subjects was tested using the natural logarithms of dose-normalized Cmax and AUC following single dosing (Study 1) or for steady-state dose-normalized Cmax, Ctrough, and AUC following multiple dosing (Study 2—Part 1) assessments. Attainment of steady-state following multiple doses in healthy volunteers was assessed by testing the logarithmic transformation of Compound 1 morning pre-dose concentrations for Study Days 5, 6, 7, 13, and 14 by repeated measures analysis. Statistical analyses were performed using SAS software (Version 9.3; SAS institute Inc., Cary, NC, USA).
Results
Demographics and Subject Disposition
A total of 56 healthy subjects were enrolled in and completed the single-dose evaluation (Study 1) and 44 healthy subjects were enrolled in and completed the multiple-dose evaluation (Study 2—Part 1). Enrollment in the multiple-dose evaluation in subjects with RA (Study 2—Part 2) was discontinued early due to slow recruitment rate and 14 subjects with RA were actually enrolled and completed this evaluation. No early withdrawals occurred in any of the three evaluations. A summary of demographic data is presented in Table 54-A.
Compound 1 Single- and Multiple-Dose Pharmacokinetics in Healthy Volunteers
Compound 1 plasma concentrations reached peak levels at approximately 1 to 2 hours after oral dosing of the immediate release capsule formulation. Compound 1 plasma concentrations declined bi-exponentially afterwards with a terminal elimination t1/2 of approximately 6 to 15 hours after single dosing (
The relationships of dose-normalized Cmax and AUC values versus dose following single and multiple dosing are presented in
Following multiple dosing in healthy subjects, there was no statistically significant difference (p >0.05) in Compound 1 dose-normalized steady-state Cmax, Ctrough, or AUC for the 24 mg twice-daily regimen compared to the 3, 6, or 12 mg twice-daily regimens.
Overall, Compound 1 exposures appeared to be dose proportional particularly over the single dose range of 3 to 36 mg and the multiple dose range of 3 mg to 24 mg BID.

Compound 1 Multiple-Dose Pharmacokinetics in Subjects with RA
In subjects with RA who were on stable doses of methotrexate, Compound 1 plasma concentrations reached peak levels at 1 to 2 hours after dosing (Table 54-D). The mean terminal elimination half-life of Compound 1 ranged from approximately 10 to 14 hours, and the functional half-life was approximately 4 hours. The median accumulation ratio of Compound 1 after 26 days of twice-daily dosing ranged from 0.8 to 1.4. The median ratio of Compound 1 Cmax and AUC0-12 when administered with methotrexate (on Study Day 29) to those when administered without methotrexate (Study Day 28) ranged from 0.9 to 1.2, indicating a lack of significant effect of methotrexate co-administration on Compound 1 pharmacokinetics (

Effect of Compound 1 Co-Administration on Methotrexate Exposure
Pharmacokinetic parameters of methotrexate when administered before (Study Day 1) and after administration of multiple doses of Compound 1 (Day 29) are summarized in Table 54-E. Since methotrexate was administered weekly and has a short plasma half-life, no plasma accumulation was expected with repeated dosing and AUC∞ was calculated for both Days 1 and 29. The median ratio for methotrexate AUC∞ and Cmx when administered after multiple doses of Compound 1 (on Study Day 29) to that when administered without Compound 1 (on Study Day 1) ranged from 0.9 to 1.1 and from 0.8 to 1.2, respectively. There was no observed change in methotrexate dose-normalized AUC when administered with or without Compound 1 (

Safety and Tolerability
Across all three evaluations, a total of 74 healthy subjects and 11 subjects with RA received Compound 1 and a total of 26 healthy subjects and 3 subjects with RA received placebo. There were no dose-limiting toxicities or safety concerns with Compound 1 from the single doses up to 48 mg or multiple doses up to 24 mg twice daily. Notably, the safety and tolerability profile of Compound 1 was comparable between subjects who received Compound 1 or placebo, and between healthy subjects and subjects with RA on background treatment of methotrexate, though the number of subjects with RA was limited. There was no evidence of a dose or time dependency for the incidence of adverse events in either healthy subjects or subjects with RA. There were no study discontinuations due to adverse events, no serious adverse events and no clinically significant changes in ECG parameters, or laboratory metrics in any of the subjects or treatment groups. The maximum tolerated dose of Compound 1 was not reached in the single or multiple dose studies. Adverse events that were reported by at least two subjects in Compound 1 or placebo groups in Study 1 or Study 2—Part 1 are presented in Table 54-F.
In healthy subjects who were administered single doses of either Compound 1 (1, 3, 6, 12, 24, 36, and 48 mg) or placebo in Study 1, 14.3% (6/42) and 21.4% (3/14) of subjects, respectively, reported to have one or more treatment-emergent adverse events (TEAEs). All TEAEs were assessed as mild in severity. The adverse events reported by more than one subject who received Compound 1 were headache and presyncope (1 subject in 6 mg and 1 subject in 24 mg dose group) in association with venipuncture (see Table 54-F).
In healthy subjects who were administered multiple doses of Compound 1 (3, 6, 12, and 24 mg BID) or placebo for 14 consecutive days in Study 2—Part 1, 34% (11/32) and 58% (7/12) of subjects, respectively, reported one or more TEAEs. The overall incidences of TEAEs were numerically higher at higher doses of Compound 1; 2 (25.0%), 2 (25.0%), 3 (37.5%) and 4 (50%) subjects in the 3 mg, 6 mg, 12 mg and 24 mg dose groups, respectively; however, these rates were lower than that was observed in the placebo group (58%). All TEAEs were reported as mild in severity. Four events occurred in at least two subjects who received Compound 1: headache, abdominal pain, diarrhea, and nasopharyngitis; three of these events also occurred in subjects who received placebo: headache, diarrhea and nasopharyngitis (Table 54-F).
There were no clinically significant changes in any hematologic parameters after multiple-dose administration in healthy subjects for 14 days. With increasing doses of Compound 1, there were statistically significant downward trends in mean levels of hemoglobin, RBCs, WBCs and neutrophils; however, even at the 24 mg dose, the mean levels were within the normal reference range. The mean changes in reticulocyte counts with increasing dose of Compound 1 compared to placebo were not statistically significant, suggesting no evidence of a dose related effect on reticulocyte counts after 14 days of Compound 1 treatment. Total cholesterol, HDL-cholesterol, and LDL-cholesterol showed a statistically significant upward trend with increasing Compound 1 dose compared with placebo; however, the final mean values for these lipid parameters in the Compound 1 dose groups remained within the normal reference range.
Subjects with mild to moderate RA on stable background doses of methotrexate, in Study 2-Part 2, were administered multiple doses of Compound 1 (a total of 11 subjects) or placebo (a total of 3 subjects). Five subjects in the Compound 1 dose groups and two subjects in the placebo group experienced at least one TEAE. In the Compound 1 dose groups, 7 TEAEs were reported: nausea, vomiting, viral gastroenteritis, upper respiratory tract infection, post-traumatic neck syndrome, back pain, and insomnia. All TEAEs were reported by the investigators as mild or moderate in severity, and no adverse event was reported in more than one subject in any treatment group. There was no evidence of a dose relationship with any of these events. Notably, as these subjects with RA received a stable background dose of methotrexate, there were no changes in hepatobiliary metrics for those receiving Compound 1. There was also no evidence of a Compound 1 dose-related effect on renal function in these subjects with RA, as evaluated by serum creatinine and blood urea nitrogen values.
Compound 1 was well-tolerated after single doses up to 48 mg and multiple twice daily doses up to 24 mg of Compound 1 immediate-release formulation. All adverse events occurred after single- or multiple-dose administrations were mild to moderate in nature with comparable frequency between subjects who received Compound 1 or placebo. No anemia, serious infections, or clinically significant changes in hematology, hepatobiliary or renal laboratory metrics was observed with 14 days of repeated Compound 1 dosing in healthy volunteers or 27 days of dosing in RA patients.
Compound 1 displayed multi-exponential plasma disposition with a functional half-life of 3 to 4 hours across the dose range of 3 to 24 mg twice daily of the immediate-release formulation in healthy volunteers and subjects with RA. The terminal elimination half-life of Compound 1 ranged from 6 to 16 hours across the different dose levels. However, given the multi-exponential disposition of Compound 1, the longer terminal half-life is less relevant clinically than the functional half-life (Dutta et al., Clin. Drug Investig., 2006, Vol. 26(12), pp. 681-690; Sahin, Pharm. Res., 2008, Vol. 25(12), pp. 2869-77). Consistent with a shorter functional half-life, there was no accumulation across the evaluated 3 to 24 mg twice-daily dose range. While there are no solid clinical data to suggest that extended exposure is needed for efficacy of JAK inhibitor (i.e. to determine whether efficacy is concentration driven or AUC driven), the pharmacokinetic profile of the immediate-release formulation of Compound 1 appears to be generally more suited for twice-daily dosing than for once-daily dosing.
Compound 1 displayed dose-proportional pharmacokinetics particularly over the 3 to 36 mg dose range (
It has been reported previously that the JAK inhibitors tofacitinib and filgotinib have higher exposures in subjects with RA than those in healthy volunteers (see FDA, “Clinical Pharmacology and Biopharmaceutics Review(s)—Tofacitinib”, Application Number 203214Orig1s000, Center for Drug Evaluation and Research, 2011; Namour et al., Clin. Pharmacokinet., 2015, Vol. 54, pp. 859-874). Compound 1's apparent oral clearance was 23% lower in subjects with RA (leading to approximately 30% higher exposure), on average across all dose groups, compared to healthy subjects. In general, older subjects are expected to have lower renal and metabolic capacity compared to younger subjects (Mangoni, Br. J. Clin. Pharmacol., 2004, Vol. 57(1), pp. 6-14). RA subjects who received multiple-doses of Compound 1 were 26 years older, on average, than the healthy subjects evaluated in Study 2 (Table 54-A); therefore, age cannot be excluded as potential contributor to the apparently 30% higher exposure of Compound 1 in RA subjects than in healthy subjects.
Methotrexate remains the first line therapy for treatment of RA and is often used with biologic DMARDs or in combination with other csDMARDs (see Ma, et al., Rheumatology (Oxford), 2010, Vol. 49(1), pp. 91-8; Singh, et al., Arthritis Care Res. (Hoboken), 2012, Vol. 64(5), pp. 625-39; Smolen, et al., Ann. Rheum. Dis., 2014, Vol. 73(3), pp. 492-509). Therefore, at least in a subset of the RA patients, it is expected that Compound 1 will be added to the first line therapy, methotrexate; thus, it was important to confirm a lack of any potential interaction between Compound 1 and methotrexate. The ratios of Compound 1 AUC and Cmax values when administered with methotrexate to those when administered alone indicate lack of significant effect of methotrexate on Compound 1 (Table 54-D;
In summary, Compound 1 displayed favorable safety and tolerability profiles over single doses up to 48 mg and multiple doses up to 24 mg twice daily for 14 days in healthy subjects and for 27 days in subjects with RA. Compound 1 demonstrated a pharmacokinetic profile suitable for twice-daily dosing with the immediate release formulation. There was no pharmacokinetic interaction between methotrexate and Compound 1 and there was no accumulation of Compound 1 with repeated administration.
The following example briefly describes the results of a Phase 2b, 12-week, randomized, double-blind, parallel-group, placebo-controlled study in which adult subjects with moderately to severely active rheumatoid arthritis (RA) who have inadequately responded to or who are intolerant to an anti-tumor necrosis factor (TNF) therapy were treated with Compound 1.
The study was conducted in accordance with the International Conference on Harmonisation guidelines, applicable regulations, and the principles of the Declaration of Helsinki. The study protocol was approved by an independent ethics committee or institutional review board. All patients provided written informed consent before participating in any study-related procedures.
Participants
Adult men and women aged 18 years or older, who had been diagnosed with RA and fulfilled either the 1987 revised American College of Rheumatology (ACR) classification criteria (Arnett et al, Arthritis Rheum., 1988, Vol. 31(3), pp. 315-324) or the 2010 ACR/European League Against Rheumatism (EULAR) criteria (Smolen et al, Ann. Rheum. Dis., 2010, Vol. 69(6), pp. 964-975) were enrolled in the study. Active RA was defined as subjects having ≥6 swollen joints (based on a 66-joint count); ≥6 tender joints (based on a 68-joint count); and high-sensitivity C-reactive protein (hsCRP) >upper limit of normal (ULN=5 mg/L) or seropositivity for both rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP). Eligible subjects must have been treated with ≥1 anti-TNF biologic agent for 3 months but continued to experience active RA, or discontinued anti-TNF biologic therapy because of intolerance or toxicity. In addition, subjects with prior exposure to non-anti-TNF biologic therapy were allowed to enroll, as long as they had failed ≥1 anti-TNF biologic. All biologic therapies had to be washed out prior to randomization: ≥4 weeks for etanercept, ≥8 weeks for adalimumab, infliximab, certolizumab, and golimumab, >8 weeks for abatacept, >12 weeks for tocilizumab, and >1 year for rituximab. A stable dose of methotrexate (7.5-25 mg/week) was required throughout the study. Key exclusion criteria were prior exposure to a JAK inhibitor, or a need for any immunosuppressant other than methotrexate. Subjects with serum aspartate transaminase (AST) or alanine transaminase (ALT)>1.5×ULN or absolute neutrophil count (ANC)<1,200/μL or absolute lymphocytes count <750/μL at screening were excluded.
Study Design and Treatment
The study was a phase 2b, 12-week, randomized, double-blind, parallel-group, placebo-controlled study conducted at 123 sites, enrolling patients in the United States (176 patients, 64%) and Puerto Rico (11 patients, 4%); Australia and New Zealand (6 patients, 2%); Western Europe including Belgium, Spain and Great Britain (29 patients, 11%); Eastern Europe including Czech Republic, Hungary, Poland (54 patients, 20%).
Subjects were equally randomized to receive oral immediate-release doses of Compound 1 (immediate release capsules comprising Tartrate Hydrate) at 3 mg BID, 6 mg BID, 12 mg BID or 18 mg BID, or matching placebo BID, for 12 weeks. Randomization was performed centrally, according to a blocked randomization schedule, by investigators enrolling via an interactive voice response system. Subjects, caregivers, investigators, joint assessors, and the study team were blinded to the treatment administered. Placebo and Compound 1 capsules were identical in appearance. Subjects should have been taking an oral supplement of folic acid (or equivalent) from four weeks prior to baseline and throughout the study. Subjects were allowed to continue stable doses of methotrexate and non-steroidal anti-inflammatory drugs (NSAIDS), acetaminophen, or oral corticosteroids (equivalent to prednisone 10 mg).
Assessments
The primary efficacy endpoint was the proportion of subjects achieving an ACR20 response at Week 12. Secondary endpoints included the proportions of subjects achieving an ACR50/ACR70 response and the proportion of subjects achieving 28-joint count disease activity score based on C-reactive protein (DAS28(CRP)) ≤3.2, or <2.6, at Week 12. Among the other endpoints were the proportion of subjects achieving low disease activity (LDA) or clinical remission (CR) based on Clinical Disease Activity Index (CDAI) criteria (LDA, CDAI ≤10; CR, ≤2.8); change in DAS28(CRP), and change in the Health Assessment Questionnaire-Disability Index (HAQ-DI) (Anderson et al, Arthritis Care Res. (Hoboken), 2012, Vol. 64(5), pp. 640-647), including the proportion of subjects achieving minimal clinically important difference (MCID) of −0.22 (Strand et al, Rheumatology (Oxford), 2006, Vol. 45(12), pp. 1505-1513). A post hoc analysis was performed to determine the proportion of subjects who had a sustained ACR20 response, defined as achievement of the ACR20 criteria at every visit (at Weeks 2, 4, 6, 8 and 12).
Safety was evaluated at each scheduled visit during treatment and for 30 days after the last dose of study drug on the basis of AEs, serious AEs, vital signs, and laboratory tests (hematology, blood chemistry, and urinalysis). Adverse events were coded according to the Medical Dictionary for Regulatory Activities (MedDRA, version 17.1). Descriptions of AE severity and post-baseline laboratory changes were based on the Rheumatology Common Toxicity Criteria v.2.0, developed by the OMERACT Drug Safety Working Group (Woodworth et al., 2007, J Rheumatol., Vol. 34(6), ppl. 1401-14).
Statistical Methods
All efficacy analyses were conducted in modified intent-to-treat population, which consisted of all randomized patients who received ≥1 dose of study drug. For ACR response rates, the last observation carried forward (LOCF) was the primary missing data imputation method and non-responder imputation (NRI) was also used to assess the robustness of the results. For continuous endpoints including DAS28 (CRP), LOCF missing data imputation was implemented; NRI is reported for binary endpoints. Binary endpoints including ACR response rates were analyzed using chi-square test with normal approximation when comparing each Compound 1 treatment group to placebo group. Continuous endpoints were analyzed using an Analysis of Covariance (ANCOVA) model with treatment group as a factor and baseline measurement as the covariate. The Multiple Comparison Procedure and Modeling (MCPMod) method was implemented to detect any non-flat dose-response relationship by evaluating several non-linear dose-response models at the same time. P-values were not corrected for multiple comparisons.
Assuming ACR20 response rates of 25% in the placebo group and 55% in any Compound 1 group, a sample size of 50 subjects per group (250 patients total) was estimated to provide at least 80% power to detect a 30% difference in response rates between the placebo group and an Compound 1 group when using a 1-sided test with an alpha level of 0.05.

Safety
The percentage of subjects with any treatment-emergent AEs was numerically higher in a dose-dependent manner for the Compound 1 6, 12 and 18 mg BID treatment groups compared with placebo (Table 55-C). Most reported AEs were considered mild to moderate in severity. The most commonly observed AEs were headache, nausea, upper respiratory tract infection, and urinary tract infection. The incidences of serious AEs and severe AEs were low, without an apparent dose-response relationship (Table 55-C). Five subjects in the Compound 1 dose groups reported seven serious AEs (3 mg BID; one subject each with pancreatitis and pulmonary embolism, 6 mg BID; one subject with pulmonary embolism and deep vein thrombosis, one patient with TIA and benign prostate hyperplasia, 18 mg BID dose; one subject acute respiratory failure). One subject on placebo experienced a serious AE of bronchiectasis. The overall infection rates were similar for the Compound 1 3- and 6 mg BID dose groups and placebo (20%, 22%, and 23%, respectively), but were higher in the Compound 1 12- and 18 mg BID dose groups (40% and 38%). No serious infections were reported in any of the Compound 1 treatment groups. Herpes zoster occurred in two subjects in the placebo group (4%) and three subjects who received Compound 1 (1%, one case each in the 3-, 12- and 18 mg BID groups; all were isolated to a single dermatome). The two reported events of hepatic disorders in the 18 mg BID dose group and one event in the placebo group were attributed to increased transaminases; none were serious. There was an adjudicated case of transient ischemic attack (left ventricular hypertrophy, classified as mild) in one subject in the Compound 1 6 mg BID group. One patient in the 6 mg BID group had one event each of basal cell carcinoma and squamous cell carcinoma. There were no opportunistic infections or deaths during the study period.
Dose-dependent increases in low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were observed; however, the ratios of LDL-C/HDL-C remained the same through Week 12. Of the subjects with normal AST or ALT at baseline, 6-18% of patients on Compound 1 had elevated AST at least twice, and 4-11% had elevated ALT at least twice, versus 2% and 6% on placebo, respectively. The number of these subjects was higher in the higher dose groups. Most of the elevations were Grade 1 (for AST and ALT, ≥1.2-<1.6×ULN) and Grade 2 (1.6-3.0×ULN). One subject each (2%) in the Compound 1 3 mg BID and placebo group (2%) had a Grade 3 ALT elevation (3.0-8.0×ULN). Of the subjects with normal creatinine at baseline, 4-14% subjects on Compound 1 had elevated creatinine at least twice versus none in the placebo group. One subject in the 18 mg BID group had a Grade 3 elevation (≥1.9-≤3.0×ULN). The elevations did not result in discontinuation of any subject from the study.
Decreases from baseline in mean hemoglobin levels were observed in a dose-dependent manner with Compound 1, although mean hemoglobin levels remained within the normal range across all dose groups during the study (
Decreases in mean circulating leukocytes, neutrophils (Table 55-D) and natural killer (NK) cells were also observed, and one subject discontinued study drug due to leukopenia. Only NK cell reductions appeared to be dose-related. The mean percentage change in NK cells was +16.5±46.6 in the placebo group; a dose-dependent decrease was seen in subjects treated with Compound 1 (−15.8±25.3 in the 3 mg BID group, −18.3±47.4 in the 6 mg BID group, −28.0±37.3 in the 12 mg BID group, and −42.6±31.7 in the 18 mg BID group). At all doses of Compound 1, there was a transient mean increase in total lymphocytes, which returned to baseline level by Week 12, except in the 18 mg dose group. There were two subjects in the 18 mg dose group with Grade 4 lymphocyte reduction; one subject was reported to have vaginal and urinary tract infection, and the other herpes zoster. One subject had a Grade 4 neutrophil reduction, which was not associated with a serious infection.

In this study, abroad dose range of Compound 1 (dosed up to 18 mg BID) was tested to assess efficacy and safety in subjects with an inadequate response or intolerance to anti-TNF biologic therapies. At all doses, Compound 1 demonstrated rapid and robust efficacy as shown by significantly greater improvements in clinical and functional outcomes compared to placebo. The onset of improvement with Compound 1 treatment was rapid with up to 58% of subjects achieving an ACR20 response as early as 2 weeks after treatment. The proportion of ACR20 responders reached a maximum at 8 weeks and plateaued at 71% through Week 12. Improvements in ACR50 (up to 42%) and ACR70 (up to 25%) response rates in the Compound 1 groups also reached a maximum before Week 12. The speed of the response is in contrast to the 3-6 months observed for many biologic therapies (Bathon, et al., The New England Journal of Medicine, 2000, Vol. 343(22), pp. 1586-93; Keystone, et al., Arthritis and Rheumatism, 2008, Vol. 58(11), pp. 3319-29; Keystone, et al., Arthritis and Rheumatism, 2004, Vol. 50(5), pp. 1400-11) and comparable with that observed for other JAK inhibitors, baracitinib and tofacitinib in TNF-IR patients. (Burnester, et al., Lancet (London, England), 2013, Vol. 381(9865), pp. 451-60; Genovese, et al., European League Against Rheumatism, 2015; 2015). In addition, the ACR20 response rate was comparable between subjects with two or more prior anti TNF therapies and those with only one prior anti-TNF. In general, the maximum efficacy was observed at the 12 mg BID dose.
Despite producing significant clinical improvement in different spectra of RA patients, there are safety concerns with JAK inhibitors, predominantly around impairing the body's ability to fight infections, viral reactivation, as well as altering hematopoietic homeostasis that could link to anemia. The most commonly reported adverse events with JAK inhibitors are infections, herpes zoster, pulmonary tuberculosis, cryptococcal pneumonia and pneumocystis pneumonitis (Fleischmann, et al., Arthritis Rheumatol., 2015, Vol. 67(2), pp. 334-43; Genovese, et al., Arthritis Rheumatol., 2016, Vol. 68(1), pp. 46-55). In addition, increases in total cholesterol, elevation of transaminase and serum creatinine, decreases in neutrophil counts and anemia are also observed. (Burnester, et al., Lancet (London, England), 2013, Vol. 381(9865), pp. 451-60; Genovese, et al., Arthritis Rheumatol., 2016, Vol. 68(1), pp. 46-55; Keystone, et al., Annals of the Rheumatic Diseases, 2015, Vol. 1 74(2), pp. 333-40).
In the current study, a broad range of doses of Compound 1 were tested to assess the selectivity of Compound 1 in vivo. Overall, Compound 1 demonstrated an acceptable safety and tolerability profile at all doses in this refractory RA population. There was no serious infection, although the proportion of overall infection rates was higher at the two highest doses of Compound 1 (12 mg and 18 mg BID). The most commonly observed infections with Compound 1 were bronchitis, upper respiratory, and urinary tract infections. The incidence of herpes zoster was similar in the placebo group (two subjects, 4%) and the Compound 1 treatment groups (three subjects, 1%), and all were non-disseminated.
At the 12 mg BID and 18 mg BID doses, there was a modest decrease in mean hemoglobin levels by Week 12, although the mean hemoglobin levels remained within the normal range. Notably, in subjects with elevated hsCRP at baseline, who were receiving 3 or 6 mg BID Compound 1, mean hemoglobin levels increased compared to placebo treatment, possibly due to a reduction of systemic inflammation while minimizing inhibitory effects on JAK2.
Circulating NK cells, which function as the critical mediator of host immunity against malignancy and infections, were measured as a pharmacodynamic readout of IL-15 inhibition. With increasing doses of Compound 1 there was a greater decrease in mean circulating NK cell counts. At the maximally efficacious dose, 12 mg BID, NK cells decreased by 28% from baseline, with proportionally smaller decreases in NK cells observed at lower doses. Given the fact that IL-15 signaling involves a heterodimer of JAK1 and JAK3, this was to be expected at higher doses of Compound 1. It is unclear how much each of the heterodimeric components (JAK1 and JAK3) contributes to the overall IL-15 signaling. However, it is possible that at higher exposure of Compound 1, the threshold for in-vivo selectivity for JAK1 compared to JAK3 is lowered in the context of the JAK1/JAK3 heterodimer. Of note, for tofacitinib at 5 mg BID, the reported median decrease in NK cells at week 24 was ˜35%, with greater reduction at 10 mg BID or higher doses of tofacitinib (van Vollenhoven, et al., Annals of the Rheumatic Diseases, 2015, pp. 258-9; Addendum to Primary Clinical Review, NDA 203,214, Center for Drug Evaluation and Research). However, it is important to note that the significance of NK cell reduction, especially what is considered clinically meaningful reduction in NK cells in terms of predicting clinical events (i.e. onset of viral reactivation) is lacking. A significant association with the changes in nadir NK cells and treated infection rates with tofacitinib treatment was observed (van Vollenhoven, et al., Annals of the Rheumatic Diseases, 2015, pp. 258-9). No association of the reduced NK cells with clinical events was observed in the current study.
As reported with other JAK inhibitors, a dose-dependent elevation of low density lipoprotein cholesterol and high density lipoprotein cholesterol levels was observed with Compound 1, however, the ratio of LDL-C/HDL-C remained unchanged. For the other laboratory parameters of interest, i.e, serum transaminases, WBC, neutrophil, or lymphocytes, the mean changes were unremarkable and lacked apparent dose relationship, with only one subject discontinuing the study early due to leukopenia.
In summary, the results of the current study demonstrated safety and efficacy of a selective JAK1 inhibitor, Compound 1, in a difficult-to-treat population of RA patients who had an inadequate response or intolerance to anti-TNF biologic therapies.
The following example briefly describes the results of a Phase 2b, 12-week, randomized, double-blind, parallel-group, placebo-controlled study in which adult subjects with moderately to severely active rheumatoid arthritis (RA) who have inadequately responded to stable methotrexate therapy were treated with Compound 1.
Patients
Men and women aged ≥18 years with active RA and inadequate response to methotrexate were included in the study. Diagnosis of RA was based on the 1987 revised American College of Rheumatology (ACR) classification criteria (Arnett et al, Arthritis Rheum., 1988, Vol. 31(3), pp. 315-324) or the 2010 ACR/European League Against Rheumatism (EULAR) criteria (Smolen et al, Ann. Rheum. Dis., 2010, Vol. 69(6), pp. 964-975). Active RA was defined by minimum disease activity criteria of ≥6 swollen joints (based on 66 joint counts) at screening and baseline; ≥6 tender joints (based on 68 joint counts) at screening and baseline; and high-sensitivity C-reactive protein (hsCRP) greater than the upper limit of normal (ULN) or positive test results for both rheumatoid factor and anti-cyclic citrullinated peptide (CCP) at screening. Eligible patients had been receiving methotrexate for ≥3 months, with a stable prescription (7.5-25 mg/week) for ≥4 weeks before baseline. Stable doses of methotrexate were continued throughout the study. In addition, all patients were requested to take a dietary supplement of oral folic acid (or equivalent) from 4 weeks prior to baseline and throughout study participation. All other oral disease-modifying antirheumatic drugs (DMARDs) were discontinued before baseline for ≥5 times the mean terminal elimination half-life of the specific DMARD to ensure washout. High-potency opiates (e.g., oxycodone, methadone, morphine) were discontinued ≥4 weeks before baseline. All patients had a negative tuberculosis screening assessment or, if there was evidence of a latent tuberculosis infection, completed ≥2 weeks of tuberculosis prophylaxis or had documented completion of a full course of tuberculosis prophylaxis before baseline. Patients were allowed to receive nonsteroidal anti-inflammatory drugs, acetaminophen, oral/inhaled corticosteroids, and low-potency opiates. Patients were excluded if they had received JAK inhibitor therapy or any other investigational or approved biologic RA therapy.
Treatment
Patients were randomized in a 1:1:1:1:1:1 ratio in a double-blind manner to oral doses of Compound 1 (immediate release capsules comprising Tartrate Hydrate) 3 mg BID, 6 mg BID, 12 mg BID, 18 mg BID, or 24 mg QD (two 12 mg tablets administered at the same time), or placebo BID for 12 weeks. Patients were randomized using an interactive voice/web response system according to a blocked randomization schedule. Investigators, patients, and other study personnel were blinded to the treatment assignments throughout the study. To maintain blinding, the placebo and active treatments had an identical appearance. Patients were instructed to take their doses (6 capsules total, split into 2 batches of 3) at approximately the same times each day.
Assessments
The primary efficacy endpoint was a ≥20% improvement in ACR criteria (ACR20) at week 12. Other endpoints included ACR50 and ACR70 response rates; change in 28-joint Disease Activity Score using C-reactive protein (DAS28(CRP)); change in Clinical Disease Activity Index (CDAI); the proportion of patients achieving low disease activity (LDA) or clinical remission based on DAS28(CRP) and CDAI criteria; and change in the Health Assessment Questionnaire Disability Index (HAQ-DI). The minimal clinically important difference (MCID) on the HAQ-DI, which is a decrease of ≥0.22, (Strand et al, 2006) was also evaluated.
Safety was evaluated during treatment and for 30 days after the last dose of study drug on the basis of adverse events (AEs), vital signs, physical examinations, and laboratory tests. AEs were coded using the Medical Dictionary for Regulatory Activities (MeDRA), version 17.1.
Statistical Analyses
The per-protocol primary efficacy analysis was conducted in a modified intent-to-treat population, including all randomized patients who take at least 1 dose of study drug, with last observation carried forward (LOCF) imputation; data were also analyzed with nonresponder imputation (NRI). Statistical tests were 1-sided with a significance level of 0.05 for efficacy analyses and 2-sided with a significance level of 0.05 for all other analyses. A sample of 270 patients (45 per randomized treatment group) was targeted give 80% power to establish a real difference of 30% in the primary efficacy endpoint (ACR20 response rate at week 12), assuming the response rate would be 30% in the placebo group and 60% in at least 1 of the Compound 1 dose groups.
Results
Patients
A total of 300 patients were randomized, and 299 received placebo (n=50) or Compound 1 3 mg BID (n=50), 6 mg BID (n=50), 12 mg BID (n=50), 18 mg BID (n=50), or 24 mg QD (n=49). Overall, 91% of patients completed the study, with similar discontinuation rates across treatment groups and no apparent relationship between Compound 1 dose and discontinuation (
Efficacy
The primary per-protocol endpoint, ACR20 at week 12 (LOCF imputation), was met at every dose of Compound 1 except the lowest dose of 3 mg BID. The proportions of patients with ACR20 were 65% (P=0.153), 73% (P=0.18), 82% (P=0.001), 77% (P=0.008), and 82% (P=0.001) at 3 mg BID, 6 mg BID, 12 mg BID, 18 mg BID, and 24 mg QD, respectively, versus the placebo response rate (50%). ACR20 responses (NRI) were significantly higher with Compound 1 at 6 mg BID (68%), 12 mg BID (80%), and 24 mg QD (76%) versus placebo (46%;
Higher percentages of patients who received Compound 1 achieved DAS28(CRP) ≤3.2 or <2.6 compared with placebo. The DAS28(CRP) ≤3.2 cutoff was achieved by a significantly higher percentage of patients (41%-52%) at all doses of Compound 1 compared with placebo (20%); the <2.6 cutoff was achieved by significantly higher proportions (34%-40%) with Compound 1 compared with placebo (14%) at all doses except 24 mg QD (22%;
Improvements from baseline in ACR component scores were larger with Compound 1 compared with placebo, reaching statistical significance for most comparisons at doses of 6 mg BID and greater (Table 56-B). Changes from baseline on the HAQ-DI at week 12 with Compound 1 ranged from −0.6 to −0.8 and were significantly greater than that seen with placebo (−0.4) for all but the Compound 1 24 mg QD dose (−0.6). Numerically, more patients in the Compound 1 dose groups ≥6 mg BID (69%-88%) met the MCID at week 12 compared with placebo (67%); the study was not powered for this analysis, and the comparisons versus placebo mostly were not statistically significant.
§number (%), 95% CI
§MCID = −0.22.
As can be seen from these results, Compound 1 had an early onset of action in subjects who have demonstrated a prior inadequate response to methotrexate. In particular, ACR20 response rates improved starting at week 2, with a maximum effect achieved as early as week 6, with continued improvement in some dose groups through week 12. ACR50 (maximum efficacy up to 50%) and ACR70 (maximum efficacy up to 28%) response rates also quickly plateaued by about week 8. Compound 1 showed a dose-dependent efficacy that seemed to reach a maximum at 12 mg BID.
Safety
The safety and tolerability profile of Compound 1 across doses was acceptable (Table 56-C). Incidence of any AE was statistically significantly higher with Compound 1 overall versus placebo (45% vs 26%; P=0.012), with a trend of dose dependence. Among common AEs, those that occurred in ≥3% patients in any group were abdominal pain, abdominal pain upper, back pain, blood creatine phosphokinase increased, cough, diarrhea, dyslipidemia, dyspepsia, gastroenteritis, headache, herpes zoster, influenza, leukopenia, nasopharyngitis, upper respiratory tract infection, urinary tract infection, white blood cell count decreased, and wound. Most AEs in the Compound 1 treatment groups were mild or moderate in severity. Severe AEs occurred in 1 patient each with Compound 1 at 6 mg BID (lung cancer at posttreatment day 10 in a 79-year-old male patient with family and smoking histories; the patient died 3 months later), 12 mg BID (pyrexia), 18 mg BID (hyperbilirubinemia), and 24 mg QD (head injury). There were 2 serious AEs with Compound 1 that were considered possibly related to study drug: community-acquired pneumonia at 12 mg BID and syncope at 24 mg QD. Infections overall occurred in 20% of patients who received Compound 1 and 14% who received placebo, with no tendency towards higher rates at higher doses. Three herpes zoster infections, 1 with Compound 1 at 3 mg BID and 2 at 24 mg QD, involved 1 dermatome per patient. A patient in the Compound 1 6 mg BID group, aged 79 years and with a history of smoking, was diagnosed with lung cancer 10 days after stopping study treatment and died 3 months later.
At week 12, mean values for alanine aminotransferase (ALT) were significantly higher with Compound 1 18 mg BID than with placebo; mean values for aspartate aminotransferase (AST) were significantly higher than placebo with all Compound 1 doses >3 mg BID (Table 56-D). However, grade 3/4 ALT or AST abnormalities during the study were sporadic, with no clear dose dependence (Table 56-E). Creatinine and creatine phosphokinase levels were significantly higher in all Compound 1 dose groups compared with placebo. Compound 1 was associated with elevations in high-density and low-density lipoprotein cholesterol (HDL-C; LDL-C); HDL-C elevation was statistically significant at 6 mg BID, whereas LDL-C values were significantly higher than placebo for all Compound 1 doses; however, the ratios of LDL-C/HDL-C remained the same through week 12. There were no significant decreases in lymphocyte or neutrophil levels between placebo and Compound Idose groups by week 12. Grade 3 lymphocyte values occurred with placebo and all doses of Compound 1; grade 4 values occurred in 1 patient each with Compound 1 at 3 mg BID and 18 mg BID (Table 56-E). Grade 3 neutrophil values occurred with Compound 1 at 12 mg BID (1 patient), 18 mg BID (3 patients), and 24 mg QD (1 patient). Natural killer (NK) cell percentages were significantly lower than placebo with Compound 1 doses ≥6 nag BID (Table 56-D).
Mean changes in hemoglobin overtime in all patients, patients with hsCRP values ≤5 mg/mL, and patients with hsCRP values >5 mg/mL are shown in
†The events of herpes zoster involved 1 dermatome per patient.
‡Lung cancer at posttreatment day 10 in a 79-year-old male patient with family and smoking histories. The patient died 3 months later.

As can be seen from these results, the safety and tolerability profile of Compound 1 was acceptable across doses.
