Description

SOLID FORMULATIONS AND POLYMORPHIC FORMS OF INDOLINE INHIBITORS OF KIF18A CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority benefit of United States Provisional Patent Application No. 63 / 486,611, filed February 23, 2023, United States Provisional Patent Application No. 63 / 486,613, filed February 23, 2023, and United States Provisional Patent Application No. 63 / 611,027, filed December 15, 2023, the disclosures of which are hereby incorporated herein by reference in their entirety. FIELD

[0002] The present disclosure in some aspects relates to indoline inhibitors of KIF18A, solid- form formulations thereof, and polymorphic forms thereof. The present disclosure in some aspects relates to methods of preparing solid formulations and polymorphic forms of certain indoline KIF18A inhibitors and methods of their use for treating diseases mediated by KIF18A, such as cancer. BACKGROUND

[0003] KIF18A is a kinesin involved in assisting kinetochore-microtubule (kt-MT) attachment and chromosomal alignment during cell mitosis. Its cargo domain binds directly to protein phosphatase 1 (PP1) and carries it to the plus end of MT where PP1 dephosphorylates Hec1, a kinetochore complex component, further enhancing kt-MT attachment throughout metaphase and anaphase. Its MT-binding motor domain has ATPase activity that powers KIF18A translocation along the MT lattice, enhanced by its C-terminal MT-binding site, and caps and depolymerizes the growing microtubule at the plus end, thus dampening MT dynamics. This modulation of MT dynamics by KIF18A often occurs at the following (or trailing) sister chromatid, thereby providing a counterbalancing tension to the leading sister chromatid movement catalyzed by another kinesin Kif2C / MCAK. Loss of KIF18A function causes defective kt-MT attachments and loss of tension within the spindle in cells of high chromosome instability (CIN), leading to hyper stable, longer and multipolar spindles, mitotic arrest, centrosome fragmentation and spindle assembly checkpoint activation or cell death. KIF18A is identified from DEPMAP RNAi data re-analysis as one ofthe top candidates essential for CIN-high cells. Reported synthetic lethality screens also singled out KIF18A as a potential anticancer target whose knockdown preferentially renders CIN-high (but not CIN-low) aneuploid and whole-genome doubled cells vulnerable to death. A cellular toxicity assay in isogenic cell lines confirmed the enhanced sensitivity of CIN-high cells to KIF18A inhibitors. Ongoing in vivo mouse models using KIF18A inhibitor or knockdown demonstrated effect of inhibited tumor growth. Thus, there is a need for new agents effective in treating diseases mediated by KIF18A.

[0004] In particular, there is a need for stable solid-form formulations of KIF18A inhibitors. SUMMARY

When an alkyl residue having a specific number of carbons is named, all branched and straight chain versions having that number of carbons are intended to be encompassed; thus, for example, “propyl” includes n- propyl and isopropyl; and “butyl” includes n-butyl, sec-butyl, isobutyl and t-butyl. Examples of alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, n-butyl, sec- butyl, tert-butyl, pentyl, 2-pentyl, 3-pentyl, isopentyl, neopentyl, hexyl, 2-hexyl, 3-hexyl, and 3-methylpentyl.

[0078] When a range of values is given (e.g., C1-6alkyl), each value within the range as well as all intervening ranges are included. For example, “C1-6alkyl” includes C1, C2, C3, C4, C5, C6, C1-6, C2-6, C3-6, C4-6, C5-6, C1-5, C2-5, C3-5, C4-5, C1-4, C2-4, C3-4, C1-3, C2-3, and C1-2alkyl.

[0079] “Alkenyl” refers to an unsaturated branched or straight-chain alkyl group having the indicated number of carbon atoms (e.g., 2 to 8, or 2 to 6 carbon atoms) and at least one carbon-carbon double bond. The group may be in either the cis or trans configuration (Z or E configuration) about the double bond(s). Alkenyl groups include, but are not limited to, ethenyl, propenyl (e.g., prop-1-en-1-yl, prop-1-en-2-yl, prop-2-en-1-yl (allyl), prop-2-en-2- yl), and butenyl (e.g., but-1-en-1-yl, but-1-en-2-yl, 2-methyl-prop-1-en-1-yl, but-2-en-1-yl, but-2-en-1-yl, but-2-en-2-yl, buta-1,3-dien-1-yl, buta-1,3-dien-2-yl).

[0080] “Alkynyl” refers to an unsaturated branched or straight-chain alkyl group having the indicated number of carbon atoms (e.g., 2 to 8 or 2 to 6 carbon atoms) and at least one carbon-carbon triple bond. Alkynyl groups include, but are not limited to, ethynyl, propynyl (e.g., prop-1-yn-1-yl, prop-2-yn-1-yl) and butynyl (e.g., but-1-yn-1-yl, but-1-yn-3-yl, but-3- yn-1-yl).

[0081] “Cycloalkyl” indicates a non-aromatic, fully saturated carbocyclic ring having the indicated number of carbon atoms, for example, 3 to 10, or 3 to 8, or 3 to 6 ring carbon atoms. Cycloalkyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl, as well as bridged and caged ring groups (e.g., norbornane, bicyclo[2.2.2]octane). In addition, one ring of a polycyclic cycloalkyl group may be aromatic, provided the polycyclic cycloalkyl group is bound to the parent structure via a non-aromatic carbon. For example, a 1,2,3,4-tetrahydronaphthalen-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is a cycloalkyl group, while 1,2,3,4-tetrahydronaphthalen-5- yl (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a cycloalkyl group. Examples of polycyclic cycloalkyl groups consisting of a cycloalkyl group fused to an aromatic ring are described below.

[0082] “Cycloalkenyl” indicates a non-aromatic carbocyclic ring, containing the indicated number of carbon atoms (e.g., 3 to 10, or 3 to 8, or 3 to 6 ring carbon atoms) and at least one carbon-carbon double bond. Cycloalkenyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of cycloalkenyl groups include cyclopropenyl, cyclobutenyl, cyclopentenyl, cyclopentadienyl, and cyclohexenyl, as well as bridged and caged ring groups (e.g., bicyclo[2.2.2]octene). In addition, one ring of a polycyclic cycloalkenyl group may bearomatic, provided the polycyclic alkenyl group is bound to the parent structure via a non- aromatic carbon atom. For example, inden-1-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is considered a cycloalkenyl group, while inden-4- yl (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a cycloalkenyl group. Examples of polycyclic cycloalkenyl groups consisting of a cycloalkenyl group fused to an aromatic ring are described below.

[0083] “Aryl” indicates an aromatic carbocyclic ring having the indicated number of carbon atoms, for example, 6 to 12 or 6 to 10 carbon atoms. Aryl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). In some instances, both rings of a polycyclic aryl group are aromatic (e.g., naphthyl). In other instances, polycyclic aryl groups may include a non- aromatic ring fused to an aromatic ring, provided the polycyclic aryl group is bound to the parent structure via an atom in the aromatic ring. Thus, a 1,2,3,4-tetrahydronaphthalen-5-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered an aryl group, while 1,2,3,4-tetrahydronaphthalen-1-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is not considered an aryl group. Similarly, a 1,2,3,4-tetrahydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered an aryl group, while 1,2,3,4- tetrahydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non- aromatic nitrogen atom) is not considered an aryl group. However, the term “aryl” does not encompass or overlap with “heteroaryl”, as defined herein, regardless of the point of attachment (e.g., both quinolin-5-yl and quinolin-2-yl are heteroaryl groups). In some instances, aryl is phenyl or naphthyl. In certain instances, aryl is phenyl. Additional examples of aryl groups comprising an aromatic carbon ring fused to a non-aromatic ring are described below.

[0084] “Heteroaryl” indicates an aromatic ring containing the indicated number of atoms (e.g., 5 to 12, or 5 to 10 membered heteroaryl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon. Heteroaryl groups do not contain adjacent S and O atoms. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 2. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 1. Unless otherwise indicated, heteroaryl groups may be bound to the parent structure by a carbon or nitrogen atom, as valency permits. For example, “pyridyl” includes 2-pyridyl, 3-pyridyl and 4-pyridyl groups, and “pyrrolyl” includes 1-pyrrolyl, 2-pyrrolyl and 3-pyrrolyl groups.

[0085] In some instances, a heteroaryl group is monocyclic. Examples include pyrrole, pyrazole, imidazole, triazole (e.g., 1,2,3-triazole, 1,2,4-triazole, 1,2,4-triazole), tetrazole, furan, isoxazole, oxazole, oxadiazole (e.g., 1,2,3-oxadiazole, 1,2,4-oxadiazole, 1,3,4- oxadiazole), thiophene, isothiazole, thiazole, thiadiazole (e.g., 1,2,3-thiadiazole, 1,2,4- thiadiazole, 1,3,4-thiadiazole), pyridine, pyridazine, pyrimidine, pyrazine, triazine (e.g., 1,2,4-triazine, 1,3,5-triazine) and tetrazine.

Examples include indole, isoindole, indazole, benzoimidazole, benzotriazole, benzofuran, benzoxazole, benzoisoxazole, benzoxadiazole, benzothiophene, benzothiazole, benzoisothiazole, benzothiadiazole, 1H-pyrrolo[2,3-b]pyridine, 1H-pyrazolo[3,4-b]pyridine, 3H-imidazo[4,5- b]pyridine, 3H-[1,2,3]triazolo[4,5-b]pyridine, 1H-pyrrolo[3,2-b]pyridine, 1H-pyrazolo[4,3- b]pyridine, 1H-imidazo[4,5-b]pyridine, 1H-[1,2,3]triazolo[4,5-b]pyridine, 1H-pyrrolo[2,3- c]pyridine, 1H-pyrazolo[3,4-c]pyridine, 3H-imidazo[4,5-c]pyridine, 3H-[1,2,3]triazolo[4,5- c]pyridine, 1H-pyrrolo[3,2-c]pyridine, 1H-pyrazolo[4,3-c]pyridine, 1H-imidazo[4,5- c]pyridine, 1H-[1,2,3]triazolo[4,5-c]pyridine, furo[2,3-b]pyridine, oxazolo[5,4-b]pyridine, isoxazolo[5,4-b]pyridine, [1,2,3]oxadiazolo[5,4-b]pyridine, furo[3,2-b]pyridine, oxazolo[4,5- b]pyridine, isoxazolo[4,5-b]pyridine, [1,2,3]oxadiazolo[4,5-b]pyridine, furo[2,3-c]pyridine, oxazolo[5,4-c]pyridine, isoxazolo[5,4-c]pyridine, [1,2,3]oxadiazolo[5,4-c]pyridine, furo[3,2- c]pyridine, oxazolo[4,5-c]pyridine, isoxazolo[4,5-c]pyridine, [1,2,3]oxadiazolo[4,5- c]pyridine, thieno[2,3-b]pyridine, thiazolo[5,4-b]pyridine, isothiazolo[5,4-b]pyridine, [1,2,3]thiadiazolo[5,4-b]pyridine, thieno[3,2-b]pyridine, thiazolo[4,5-b]pyridine, isothiazolo[4,5-b]pyridine, [1,2,3]thiadiazolo[4,5-b]pyridine, thieno[2,3-c]pyridine, thiazolo[5,4-c]pyridine, isothiazolo[5,4-c]pyridine, [1,2,3]thiadiazolo[5,4-c]pyridine, thieno[3,2-c]pyridine, thiazolo[4,5-c]pyridine, isothiazolo[4,5-c]pyridine, [1,2,3]thiadiazolo[4,5-c]pyridine, quinoline, isoquinoline, cinnoline, quinazoline, quinoxaline, phthalazine, naphthyridine (e.g., 1,8-naphthyridine, 1,7-naphthyridine, 1,6- naphthyridine, 1,5-naphthyridine, 2,7-naphthyridine, 2,6-naphthyridine), imidazo[1,2- a]pyridine, 1H-pyrazolo[3,4-d]thiazole, 1H-pyrazolo[4,3-d]thiazole and imidazo[2,1- b]thiazole.

[0087] In other instances, polycyclic heteroaryl groups may include a non-aromatic ring (e.g., cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl) fused to a heteroaryl ring,provided the polycyclic heteroaryl group is bound to the parent structure via an atom in the aromatic ring. For example, a 4,5,6,7-tetrahydrobenzo[d]thiazol-2-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is considered a heteroaryl group, while 4,5,6,7-tetrahydrobenzo[d]thiazol-5-yl (wherein the moiety is bound to the parent structure via a non-aromatic carbon atom) is not considered a heteroaryl group. Examples of polycyclic heteroaryl groups consisting of a heteroaryl ring fused to a non- aromatic ring are described below.

[0088] “Heterocycloalkyl” indicates a non-aromatic, fully saturated ring having the indicated number of atoms (e.g., 3- to 10-, or 3- to 7-, membered heterocycloalkyl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon. Heterocycloalkyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of heterocycloalkyl groups include oxiranyl, aziridinyl, azetidinyl, pyrrolidinyl, imidazolidinyl, pyrazolidinyl, piperidinyl, piperazinyl, morpholinyl and thiomorpholinyl. Examples include thiomorpholine S-oxide and thiomorpholine S,S-dioxide. In addition, one ring of a polycyclic heterocycloalkyl group may be aromatic (e.g., aryl or heteroaryl), provided the polycyclic heterocycloalkyl group is bound to the parent structure via a non-aromatic carbon or nitrogen atom. For example, a 1,2,3,4- tetrahydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non- aromatic nitrogen atom) is considered a heterocycloalkyl group, while 1,2,3,4- tetrahydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a heterocycloalkyl group. Examples of polycyclic heterocycloalkyl groups consisting of a heterocycloalkyl group fused to an aromatic ring are described below.

[0089] “Heterocycloalkenyl” indicates a non-aromatic ring having the indicated number of atoms (e.g., 3- to 10-, or 3- to 7-, membered heterocycloalkenyl) made up of one or more heteroatoms (e.g., 1, 2, 3 or 4 heteroatoms) selected from N, O and S and with the remaining ring atoms being carbon, and at least one double bond derived by the removal of one molecule of hydrogen from adjacent carbon atoms, adjacent nitrogen atoms, or adjacent carbon and nitrogen atoms of the corresponding heterocycloalkyl. Heterocycloalkenyl groups may be monocyclic or polycyclic (e.g., bicyclic, tricyclic). Examples of heterocycloalkenyl groups include dihydrofuranyl (e.g., 2,3-dihydrofuranyl, 2,5-dihydrofuranyl), dihydrothiophenyl (e.g., 2,3-dihydrothiophenyl, 2,5-dihydrothiophenyl), dihydropyrrolyl (e.g., 2,3-dihydro-1H-pyrrolyl, 2,5-dihydro-1H-pyrrolyl), dihydroimidazolyl (e.g., 2,3-dihydro-1H-imidazolyl, 4,5-dihydro-1H-imidazolyl), pyranyl, dihydropyranyl (e.g., 3,4- dihydro-2H-pyranyl, 3,6-dihydro-2H-pyranyl), tetrahydropyridinyl (e.g., 1,2,3,4- tetrahydropyridinyl, 1,2,3,6-tetrahydropyridinyl) and dihydropyridine (e.g., 1,2- dihydropyridine, 1,4-dihydropyridine). In addition, one ring of a polycyclic heterocycloalkenyl group may be aromatic (e.g., aryl or heteroaryl), provided the polycyclic heterocycloalkenyl group is bound to the parent structure via a non-aromatic carbon or nitrogen atom. For example, a 1,2-dihydroquinolin-1-yl group (wherein the moiety is bound to the parent structure via a non-aromatic nitrogen atom) is considered a heterocycloalkenyl group, while 1,2-dihydroquinolin-8-yl group (wherein the moiety is bound to the parent structure via an aromatic carbon atom) is not considered a heterocycloalkenyl group. Examples of polycyclic heterocycloalkenyl groups consisting of a heterocycloalkenyl group fused to an aromatic ring are described below.

[0090] Examples of polycyclic rings consisting of an aromatic ring (e.g., aryl or heteroaryl) fused to a non-aromatic ring (e.g., cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl) include indenyl, 2,3-dihydro-1H-indenyl, 1,2,3,4-tetrahydronaphthalenyl, benzo[1,3]dioxolyl, tetrahydroquinolinyl, 2,3-dihydrobenzo[1,4]dioxinyl, indolinyl, isoindolinyl, 2,3-dihydro-1H-indazolyl, 2,3-dihydro-1H-benzo[d]imidazolyl, 2,3- dihydrobenzofuranyl, 1,3-dihydroisobenzofuranyl, 1,3-dihydrobenzo[c]isoxazolyl, 2,3-dihydrobenzo[d]isoxazolyl, 2,3-dihydrobenzo[d]oxazolyl, 2,3-dihydrobenzo[b]thiophenyl, 1,3-dihydrobenzo[c]thiophenyl, 1,3-dihydrobenzo[c]isothiazolyl, 2,3-dihydrobenzo[d]isothiazolyl, 2,3-dihydrobenzo[d]thiazolyl, 5,6-dihydro-4H-cyclopenta[d]thiazolyl, 4,5,6,7-tetrahydrobenzo[d]thiazolyl, 5,6-dihydro-4H-pyrrolo[3,4-d]thiazolyl, 4,5,6,7- tetrahydrothiazolo[5,4-c]pyridinyl, indolin-2-one, indolin-3-one, isoindolin-1-one, 1,2- dihydroindazol-3-one, 1H-benzo[d]imidazol-2(3H)-one, benzofuran-2(3H)-one, benzofuran- 3(2H)-one, isobenzofuran-1(3H)-one, benzo[c]isoxazol-3(1H)-one, benzo[d]isoxazol-3(2H)- one, benzo[d]oxazol-2(3H)-one, benzo[b]thiophen-2(3H)-one, benzo[b]thiophen-3(2H)-one, benzo[c]thiophen-1(3H)-one, benzo[c]isothiazol-3(1H)-one, benzo[d]isothiazol-3(2H)-one, benzo[d]thiazol-2(3H)-one, 4,5-dihydropyrrolo[3,4-d]thiazol-6-one, 1,2-dihydropyrazolo[3,4- d]thiazol-3-one, quinolin-4(3H)-one, quinazolin-4(3H)-one, quinazoline-2,4(1H,3H)-dione, quinoxalin-2(1H)-one, quinoxaline-2,3(1H,4H)-dione, cinnolin-4(3H)-one, pyridin-2(1H)- one, pyrimidin-2(1H)-one, pyrimidin-4(3H)-one, pyridazin-3(2H)-one, 1H-pyrrolo[3,2- b]pyridin-2(3H)-one, 1H-pyrrolo[3,2-c]pyridin-2(3H)-one, 1H-pyrrolo[2,3-c]pyridin-2(3H)-one, 1H-pyrrolo[2,3-b]pyridin-2(3H)-one, 1,2-dihydropyrazolo[3,4-d]thiazol-3-one and 4,5- dihydropyrrolo[3,4-d]thiazol-6-one. As discussed herein, whether each ring is considered an aryl, heteroaryl, cycloalkyl, cycloalkenyl, heterocycloalkyl or heterocycloalkenyl group is determined by the atom through which the moiety is bound to the parent structure.

[0091] “Halogen” or “halo” refers to fluoro, chloro, bromo or iodo.

[0092] “Haloalkyl” refers to alkyl substituted with one or more halogen. A haloalkyl group may have a halogen substituent at any valence-permitted location on the alkyl and may have any number of halogen substituents ranging from one to the maximum valence-permitted number. Particular haloalkyl groups have 1, 2, or 3 halogen substituents. Examples of haloalkyl groups include, but are not limited to, -CH2F, -CHF2, -CF3, -CH2CH2F, -CH2CHF2, -CH2CF3, -CH2Cl, -CHCl2, -CCl3, -CH2CH2Cl, -CH2CHCl2, -CH2CCl3.

[0093] Unless otherwise indicated, compounds disclosed and / or described herein include all possible enantiomers, diastereomers, meso isomers and other stereoisomeric forms, including racemic mixtures, optically pure forms and intermediate mixtures thereof. Enantiomers, diastereomers, meso isomers and other stereoisomeric forms can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. Unless specified otherwise, when the compounds disclosed and / or described herein contain olefinic double bonds or other centers of geometric asymmetry, it is intended that the compounds include both E and Z isomers. When the compounds described herein contain moieties capable of tautomerization, and unless specified otherwise, it is intended that the compounds include all possible tautomers.

[0094] “Protecting group” has the meaning conventionally associated with it in organic synthesis, i.e., a group that selectively blocks one or more reactive sites in a multifunctional compound such that a chemical reaction can be carried out selectively on another unprotected reactive site, and such that the group can readily be removed after the selective reaction is complete. A variety of protecting groups are disclosed, for example, in T.H. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, Third Edition, John Wiley & Sons, New York (1999). For example, a “hydroxy protected form” contains at least one hydroxy group protected with a hydroxy protecting group. Likewise, amines and other reactive groups may similarly be protected.

[0095] The term “pharmaceutically acceptable salt” refers to a salt of any of the compounds herein which are known to be non-toxic and are commonly used in the pharmaceutical literature. In some embodiments, the pharmaceutically acceptable salt of a compound retainsthe biological effectiveness of the compounds described herein and are not biologically or otherwise undesirable. Examples of pharmaceutically acceptable salts can be found in Berge et al., Pharmaceutical Salts, J. Pharmaceutical Sciences, January 1977, 66(1), 1-19. Pharmaceutically acceptable acid addition salts can be formed with inorganic acids and organic acids. Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid.

In some embodiments, the pharmaceutically acceptable base addition salt is selected from ammonium, potassium, sodium, calcium, and magnesium salts.

[0096] If the compound described herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the compound is a free base, an addition salt, particularly a pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds (see, e.g., Berge et al., Pharmaceutical Salts, J. Pharmaceutical Sciences, January 1977, 66(1), 1-19). Those skilled in the art will recognize various synthetic methodologies that may be used to prepare pharmaceutically acceptable addition salts.

[0097] A “solvate” is formed by the interaction of a solvent and a compound. Suitable solvents include, for example, water and alcohols (e.g., ethanol). Solvates include hydrates having any ratio of compound to water, such as monohydrates, dihydrates and hemi-hydrates.

The term “unsubstituted” means that the specified group bears no substituents. Where the term “substituted” is used to describe a structural system, the substitution is meant to occur at any valency-allowed position on the system. When a group or moiety bears more than one substituent, it is understood that the substituents may be the same or different from one another. In some embodiments, a substituted group or moiety bears from one to five substituents. In some embodiments, a substituted group or moiety bears one substituent. In some embodiments, a substituted group or moiety bears two substituents. In some embodiments, a substituted group or moiety bears three substituents. In some embodiments, a substituted group or moiety bears four substituents. In some embodiments, a substituted group or moiety bears five substituents.

[0099] By “optional” or “optionally” is meant that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” encompasses both “alkyl” and “substituted alkyl” as defined herein. It will be understood by those skilled in the art, with respect to any group containing one or more substituents, that such groups are not intended to introduce any substitution or substitution patterns that are sterically impractical, synthetically non-feasible, and / or inherently unstable. It will also be understood that where a group or moiety is optionally substituted, the disclosure includes both embodiments in which the group or moiety is substituted and embodiments in which the group or moiety is unsubstituted.

[0100] The compounds disclosed and / or described herein can be enriched isotopic forms, e.g., enriched in the content of2H,3H,11C,13C and / or14C. In one embodiment, the compound contains at least one deuterium atom. Such deuterated forms can be made, for example, by the procedure described in U.S. Patent Nos. 5,846,514 and 6,334,997. Such deuterated compounds may improve the efficacy and increase the duration of action of compounds disclosed and / or described herein. Deuterium substituted compounds can be synthesized using various methods, such as those described in: Dean, D., Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development, Curr. Pharm. Des., 2000; 6(10); Kabalka, G. et al., The Synthesis ofRadiolabeled Compounds via Organometallic Intermediates, Tetrahedron, 1989, 45(21), 6601-21; and Evans, E., Synthesis of radiolabeled compounds, J. Radioanal. Chem., 1981, 64(1-2), 9-32.

[0101] The term “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” includes any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in pharmaceutical compositions is contemplated. Supplementary active ingredients can also be incorporated into the pharmaceutical compositions.

[0102] As used herein, the terms “polymorph”, “polymorphic”, “polymorphic form”, or “crystalline form”, which are used interchangeably, refer to polymorphic form of a compound. The polymorphic form can be crystalline or amorphous. Different polymorphs may have different physical properties such as, for example, melting temperatures, heats of fusion, solubilities, dissolution rates, and / or vibrational spectra as a result of the arrangement or conformation of the molecules or ions in the crystal lattice. The differences in physical properties exhibited by polymorphs may affect pharmaceutical parameters, such as storage stability, compressibility, density (important in formulation and product manufacturing), and dissolution rate (an important factor in bioavailability). Differences in stability can result from changes in chemical reactivity (e.g., differential oxidation, such that a dosage form discolors more rapidly when comprised of one polymorph than when comprised of another polymorph), mechanical changes (e.g., tablets crumble on storage as a kinetically favored polymorph converts to thermodynamically more stable polymorph), or both (e.g., tablets of one polymorph are more susceptible to breakdown at high humidity). As a result of solubility / dissolution differences, in the extreme case, some polymorphic transitions may result in lack of potency or, at the other extreme, toxicity. In addition, the physical properties of a crystalline form may be important in processing; for example, one polymorph might be more likely to form solvates or might be difficult to filter and wash free of impurities (e.g., particle shape and size distribution might be different between polymorphs).

[0103] As used herein, the term “substantially as shown in” when referring, for example, to an XRPD pattern, a DSC graph, a TGA graph, or a GVS graph, includes a pattern or graph that is not necessarily identical to those depicted herein, but that falls within the limits of experimental error or deviations when considered by one of ordinary skill in the art.

[0104] As used herein, the term “substantially free of” means that the composition comprising the crystalline form contains less than 50%, less than 40%, less than 30%, less than 20%, less than 15%, less than 10%, less than 5%, less than 4%, less than 3%, less than 2%, or less than 1% by weight of the indicated substance or substances.

[0105] The terms “patient”, “individual”, and “subject” refer to an animal, such as a mammal, bird, or fish. In some embodiments, the patient or subject is a mammal. Mammals include, for example, mice, rats, dogs, cats, pigs, sheep, horses, cows and humans.

[0159] Also provided herein is a process of preparing the solid pharmaceutical formulations described herein. In some embodiments, the process comprises spray-drying a solution of a compound of Formula (A) (e.g., a compound of Formula (A-1), Formula (A-2), or Formula (A-3)) to obtain an amorphous solid dispersion of a compound of Formula (A) (e.g., a compound of Formula (A-1), Formula (A-2), or Formula (A-3)).

[0160] Spray-dried solid dispersion or spray-dried dispersion (SDD) is a solid dispersion produced using spray-drying technology. Spray drying processes generally involve breaking up liquid mixtures from a solution into small droplets, a step also known as atomization, and rapidly removing solvent from the mixture in a container (e.g., a spray-drying apparatus), where a strong driving force is provided to evaporate solvent from the droplets. A portion of the driving force for evaporation of solvent from the droplets may be provided by heating the solution. Spray-drying processes and spray-drying equipment or apparatus are described generally in, for example, Perry's Chemical Engineers' Handbook (Eighth Edition 2007). The strong driving force for solvent evaporation is generally provided by maintaining the partial pressure of solvent in the spray-drying apparatus well below the vapor pressure of the solvent at the temperature of the drying droplets. The strong driving force for solvent evaporation may be accomplished by (1) maintaining the pressure in the spray-drying apparatus at apartial vacuum (e.g., 0.01 to 0.50 atm); (2) mixing the liquid droplets with a warm drying gas; or the combination of both (1) and (2).

[0161] In some embodiments, the process comprises spray-drying a solution comprising: (i) a compound of Formula (A) (e.g., a compound of Formula (A-1), Formula (A-2), or Formula (A-3)) or a pharmaceutically acceptable salt thereof; (ii) a polymer; and (iii) a solvent. In some embodiments, the process comprises (1) preparing a solution comprising (i) a compound of Formula (A) (e.g., a Formula (A-1), Formula (A-2), or Formula (A-3)) or a pharmaceutically acceptable salt thereof; (ii) a polymer; and (iii) a solvent; (2) spray-drying the solution to obtain a powder; and optionally (3) further drying the powder of step (2) under heat. In some embodiments, the solvent comprises dichloromethane (DCM). In some embodiments, the solvent comprises alcohol. In some embodiments, the solvent comprises methanol. In some embodiments, the solvent comprises DCM and methanol. In some embodiments, the solvent comprises water. In some embodiments, the solvent comprises acetone. In some embodiments, the solvent comprises acetone and water. In some embodiments, the solvent is a mixture of acetone and water, optionally in a volume ratio of about 50:1 to about 1:50, such as about any of 30:1 to 1:30, 30:1 to 1:10, 30:1 to 1:1, 20:1 to 1:1, 15:1 to 1:1, 10:1 to 1:10, 10:1 to 1:1, 10:1 to 5:1, 12:1, 11:1, 10:1, 9:1, 8:1, 7:1, 6:1, or 5:1.

[0162] In one aspect, provided herein are polymorphic forms of N-(1''-(3-(((tert- butylamino)methyl)sulfonyl)benzoyl)dispiro[cyclopropane-1,1'-cyclohexane-4',3''-indolin]- 5''-yl)ethanesulfonamide, also referred herein as a compound of Formula (A-1), having the structure shown below,

[0163] In some embodiments, compound of Formula (A-1) is also referred to as N-(tert- butyl)-3-(5''-(ethylsulfonamido)dispiro[cyclopropane-1,1'-cyclohexane-4',3''-indoline]-1''- carbonyl)benzenesulfonamide.

[0164] The polymorphs may have properties such as bioavailability and stability under certain conditions that are suitable for medical or pharmaceutical uses.

[0165] A polymorph of the compound of Formula (A-1) may provide the advantages of bioavailability and stability and may be suitable for use as an active agent in a pharmaceutical composition. Variations in the crystal structure of a pharmaceutical drug substance may affect the dissolution rate (which may affect bioavailability, etc.), manufacturability (e.g., ease of handling, ease of purification, ability to consistently prepare doses of known strength, etc.) and stability (e.g., thermal stability, shelf life (including resistance to degradation), etc.) of a pharmaceutical drug product. Such variations may affect the methods of preparation or formulation of pharmaceutical compositions in different dosage or delivery forms, such as solid oral dosage forms including tablets and capsules. Compared to other forms such as non- crystalline or amorphous forms, polymorphs may provide desired or suitable hygroscopicity or lack thereof, particle size control, dissolution rate, solubility, purity, physical and chemical stability, manufacturability, yield, reproducibility, and / or process control. Thus, polymorphs of the compound of Formula (A-1) may provide advantages of improving the manufacturing process of the active agent or the stability or storability of a drug product form of the active agent, or having suitable bioavailability and / or stability as an active agent.

[0166] The use of certain conditions, such as the use of different solvents and / or temperatures, may produce different polymorphs of the compound of Formula (A-1) or a solvate thereof, including the polymorphic Form A and polymorphic form C described herein, which may exhibit one or more favorable characteristics described herein. The processes for the preparation of the polymorphs described herein and characterization of these polymorphs are described in greater detail below.III-a. Polymorphic Form A (Free-Form Pattern A)

Materials, Methods, and Abbreviations Differential Scanning Calorimetry (DSC)

[0329] DSC was performed using a TA Instruments Discovery DSC2500 differential scanning calorimeter equipped with a TA instruments Refrigerated Cooling System 90 operating in either modulated or ramp mode. DSC was used to measure thermodynamic properties SDIs prepared herein, including the following: glass transition temperature (Tg) defined as the temperature at which amorphous materials transition from a low mobility glassy state to a high mobility rubbery state, cold crystallization temperature (Tc), defined as a crystallization event at a temperature lower than the melt temperature, and melting temperature (Tm). The system was purged by nitrogen flow at 50 mL / min to ensure inert atmosphere through the course of measurement.

[0330] Spray dried samples were placed in non-hermetic aluminum pans and heated at a constant rate of 2.0 °C / min. DSC parameters are summarized in Table 1-1. Table 1-1X-Ray Powder Diffraction (XRPD)

[0331] For characterization of solid formulations, XRPD was performed using a Rigaku Miniflex 6G X-ray diffractometer to evaluate the crystallinity of bulk compounds and SDDs. Amorphous materials give an “amorphous halo” diffraction pattern, absent of discrete peaks that are found in crystalline material. Samples were irradiated with monochromatized Cu Kα radiation and analyzed from 5° and 40° with a continuous scanning mode. Samples were rotated during analysis to minimize preferred orientation effects. XRPD parameters are shown in Table 1-2. Table 1-2

[0332] For characterization of polymorphic forms, both transmission geometry and reflection geometry were used.

[0333] In transmission geometry, XRPD patterns were collected with PANalytical X'Pert PRO MPD or Empyrean diffractometers using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640f) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was sandwiched between 3-μm-thick films and analyzed in transmission geometry. A beam-stop, short anti-scatter extension, and an anti-scatter knife edge were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v. 5.5.

[0334] In reflection geometry, XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu Kα radiation produced using a long, fine- focus source and a nickel filter. The diffractometer was configured using the symmetric Bragg-Brentano geometry. Prior to the analysis, a silicon specimen (NIST SRM 640f) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST- certified position. A specimen of the sample was prepared as a thin, circular layer centered on a silicon zero-background substrate. Anti-scatter slits (SS) were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using ascanning position-sensitive detector (X'Celerator) located 240 mm from the sample and Data Collector software v. 5.5.1H NMR

[0335] The proton solution NMR spectra were acquired with a Bruker AVANCE 600 MHz Spectrometer using DMSO-d6. Polarized Light Microscopy (PLM)

[0336] Light microscopy was performed using a Leica MZ12.5 stereomicroscope. Samples were observed using 0.8-10× objectives with crossed polarizers and a first order red compensator. Samples were either viewed in situ or in a drop of mineral oil. The PLM images of polymorphic forms were taken using a Leica DM LP microscope equipped with an Infinity2 color camera. Crossed polarizers with a first order red compensator and Koehler illumination was used. Samples were placed on a glass microscope slide and a 1½ cover glass is placed over the sample. Then mineral oil was added to the edge of the cover glass to cover the sample by capillarity. Images were acquired at ambient temperature using Teledyne Lumenera INFINITY ANALYZE software version 7.1.0.1215. The camera was white balanced in accordance with the Initial Camera Configuration in the software. Particle Morphology by Scanning Electron Microscopy (SEM)

[0337] SEM samples were prepared by dispersing powder onto an adhesive carbon-coated sample stub and coating with a thin conductive layer of gold-palladium using a Cressington 108 Auto. Samples were analyzed using a Phenom XL fitted with an Everhart-Thornley (secondary electron) detector or backscatter detector operating in high vacuum mode. Micrographs at various magnifications were captured for qualitative particle morphology analysis. Experimental parameters were varied from sample to sample to obtain the best imaging conditions and are documented in the caption of each micrograph. Particle Size Distribution (PSD) by Light Diffraction

[0338] The particle size distribution of SDI samples was determined by laser diffraction using a Mastersizer 3000 with an Aero S unit (Malvern Instruments). The parameters are listed in Table 1-3. Dv10, Dv50 and Dv90 diameters were used to describe the particle sizedistribution. For instance, the Dv50diameter is the diameter at which 50% of a sample’s volume is comprised of smaller particles. Table 1-3Assay and Impurities by High Performance Liquid Chromatography (HPLC)

[0339] Assay and impurities of SDI samples were evaluated using an HPLC method provided by the client. Parameters are listed in Table 1-4. The method demonstrated passing system suitability criteria for early development work, including but not limited to reproducibility, standard agreement, injector precision, tailing, and signal to noise. Table 1-4Residual Solvent by Gas Chromatography – Headspace Sampling

[0340] The residual solvent content of SDIs was measured by GC-HS after secondary drying. Measurements were made using an HP 6890 series GC equipped with an Agilent 7697A headspace sampler. A 30 m × 0.32 mm × 1.8 μ capillary column with 6% cyanopropylphenyl 94% dimethylpolysiloxane Agilent GC column PN: 123-1334 was used for the testing. GC samples were prepared by dissolving approximately 100 mg sample in 4 mL dimethyl sulfoxide (DMSO). The GC method parameters are summarized in Table 1-5, Table 1-6, and Table 1-7. Table 1-5. HP 7697A Headspace Autosampler ParametersTable 1-6. Gas Chromatograph Operating ParametersTable 1-7. Oven Temperature Gradient.TGA / DSC Combination Analyses

[0341] TGA / DSC combination analyses were performed using a Mettler Toledo TGA / DSC3+ analyzer. Temperature and enthalpy adjustments were performed using phenyl salicylate, indium, tin, and zinc, and then verified with indium. Balance was verified with calcium oxalate. The sample was placed in an aluminum pan. The pan was hermetically sealed, the lid pierced, then inserted into the TG furnace. A weighed aluminum pan configured as the sample pan was placed on the reference platform. The furnace was heated under nitrogen. Dynamic vapor sorption (DVS)

[0342] Moisture sorption / desorption data were collected on a Surface Measurement System DVS Intrinsic instrument. Samples were not dried prior to analysis. Sorption and desorption data were collected over a range from 5% to 95% RH at 10% RH increments. The equilibrium criterion used for analysis was less than 0.0100% weight change in 5 minutes with a maximum equilibration time of 3 hours. Temperature modulated differential scanning calorimetry (TMDSC)

[0343] Temperature-modulated DSC (TMDSC) was performed using a Mettler Toledo DSC3+ differential scanning calorimeter. Temperature calibration was performed using octane, phenyl salicylate, indium, tin, and zinc. The sample was placed into a hermetically sealed aluminum DSC pan, the weight was accurately recorded, and the sample was inserted into the DSC cell. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The pan lid was pierced prior to sample analysis. The sample was analyzed from −50 °C to 250 °C at 2 °C / min with a pulse height of 0.5 ºC. AbbreviationsExample S-1. Synthesis of compounds of Formula (A) General synthetic methods

[0344] Compounds of Formula (A), Formula (B), Formula (C), Formula (A-1), Formula (A- 2), and Formula (A-3) will now be described by reference to illustrative synthetic schemes for their general preparation below and the specific examples that follow. Artisans will recognize that, to obtain the various compounds herein, starting materials may be suitably selected so that the ultimately desired substituents will be carried through the reaction scheme with or without protection as appropriate to yield the desired product. Alternatively, it may be necessary or desirable to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. In addition, one of skill in the art will recognize that protecting groups may be used to protect certain functional groups (amino, carboxy, or side chain groups) from reaction conditions, and that such groups are removed under standard conditions when appropriate. Unless otherwise specified, the variables are as defined above in reference to Formula (A), Formula (B), Formula (C), Formula (A-1), Formula (A-2), or Formula (A-3).

[0345] Where it is desired to obtain a particular enantiomer of a compound, this may be accomplished from a corresponding mixture of enantiomers using any suitable conventional procedure for separating or resolving enantiomers. Thus, for example, diastereomeric derivatives may be produced by reaction of a mixture of enantiomers, e.g., a racemate, and an appropriate chiral compound. The diastereomers may then be separated by any convenient means, for example by crystallization and the desired enantiomer recovered. In another resolution process, a racemate may be separated using chiral High Performance Liquid Chromatography. Alternatively, if desired a particular enantiomer may be obtained by using an appropriate chiral intermediate in one of the processes described.

[0346] Chromatography, recrystallization and other conventional separation procedures may also be used with intermediates or final products where it is desired to obtain a particular isomer of a compound or to otherwise purify a product of a reaction.

[0347] General methods of preparing compounds described herein are depicted in exemplified methods below. Variable groups in the schemes provided herein are defined as for Formula (A), Formula (B), Formula (C), Formula (A-1), Formula (A-2), or Formula (A- 3), or any variation thereof. Other compounds described herein may be prepared by similar methods.

[0348] In some embodiments, compounds provided herein may be synthesized according to Scheme 1, Scheme 2, Scheme 3, and / or Scheme 4. Ring A, Ring B, Y1, Y2, Y3, Y4, m, RB, and RC, as shown in Schemes 1-4 below, are as defined for the compounds of Formula I. Scheme 1.

[0349] Scheme 1 outlines an exemplary route to the synthesis of compound of general formula I. Compounds of formula I are prepared by the reaction of a carboxylic acid of formula A (e.g., X = OH) and an indoline of formula B in the presence of coupling reagent, such as HATU with a base such as iPr2NEt, or EDCI with a HOBt or DMAP. Alternatively, an acid halide of formula A (e.g., X = Cl or F) is reacted directly with the compound of formula B with an acid scavenger, such as Et3N.Scheme 2.

[0350] Indoline intermediates of formula B may be prepared via the Fisher Indole Synthesis as described in Scheme 2. Arylhydrazines of formula C (e.g., formula C-i, formula C-ii, and formula C-iii) are reacted with a Ring B-substituted carbaldehyde of formula D in the presence of acid, followed by reaction with a reducing agent such as NaBH4, Pd / C and H2gas, or Et3SiH. Arylhydrazines of formula C-i, which are para-mono-substituted, provide indolines of formula B-i, while hydrazines of formula C-ii, which contain at least one meta substituent and are not substituted in the ortho positions, provide a mixture of indolines of formulae B-ii-a and B-ii-b. Arylhydrazines of formula C-iii, that are substituted at one ortho position, provide indolines of formula B-iii.Scheme 3.

[0351] Indolines of formula B may also be prepared via an 3,3-dialkylation method described in Scheme 3. An indole of formula D is reacted with an optionally substituted 3-6 atom aliphatic and heteroaliphatic linear chain with two terminal leaving groups “LG” (formula E). LG may be Cl, Br, I, or sulfonate ester, or another suitable group displaceable by a nucleophile. The transformation may be mediated by a trialkylboron, such as Et3B, and base, such as potassium t-butoxide. The spiroannulation reaction is followed by a reaction with a reducing agent such as NaBH4, Pd / C and H2gas, or Et3SiH. Scheme 4.

[0352] Indolines of formula B may also be prepared via the enolate alkylation of an indolin- 2-one of formula F. The indolin-2-one of formula F is deprotonated with a strong base, such as butyllithium, sodium hexamethylsilazide, or potassium t-butoxide, and reacted with an optionally substituted 3-6 atom aliphatic and heteroaliphatic linear chain with two terminal leaving groups “LG” (formula E). LG may be Cl, Br, I, or sulfonate ester, or another suitable group displaceable by a nucleophile. This reaction may be mediated by an additive such as tetramethyldiaminoethane or hexamethylphosphorous triamide. The spiroannulation reaction is followed by a reaction with a reducing agent such as LiAlH4or borane. Synthesis of Intermediates Synthesis of 3-(piperidin-1-ylsulfonyl)benzoic acid (A-01)
