TECHNICAL FILED:
The present invention relates to novel crystalline polymorphic forms of 4-[3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate, methods of preparation, pharmaceutical compositions and methods of therapeutic treatment involving polymorphic forms thereof.

BACKGROUND OF THE INVENTION:
4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate, compound of formula I

is an oral molecule that inhibits multiple tyrosine kinase receptors such as VEGF-R-1-3, FGF-R-1-4, RET, c-KIT and PDGF-R-ß. It blocks VEGFR2 activation by VEGF, resulting in inhibition of the VEGF receptor signal transduction pathway, decreased vascular endothelial cell migration and proliferation, and vascular endothelial cell apoptosis.

The angiogenesis inhibitor and antitumor agent, 4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide, salts or hydrates and methods for making the same are illustrated in US 7,253,286 B2 which is hereby incorporated by reference in their entirety.

US 7550483 B2, incorporated herein by reference, discloses amorphous forms of 4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate and esylate salts and a process of preparation thereof.

US 7612208 B2, incorporated herein by reference, discloses crystalline forms A, B, C, F (hydrate) and I (acetic acid solvate), DMSO solvate of 4-(3-chloro-4-(cyclopropylamino carbonyl) amino phenoxy)-7-methoxy-6-quinolinecarboxamide mesylate and crystalline forms a, ß and DMSO solvate of 4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinoline carboxamide esylate and a process of preparation thereof .

US 9334239 B2, incorporated herein by reference, discloses amorphous form of 4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide and a process of preparation thereof.

WO 2016/184436 A1 incorporated herein by reference, discloses crystalline form M of 4-(3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate and a process of preparation thereof.

The discovery of a new crystalline form of a pharmaceutically useful compound provides an opportunity to improve the performance characteristics of a pharmaceutical product. It enlarges the repertoire of materials that a formulation scientist has available for designing, for example, a pharmaceutical dosage form of a drug with a targeted release profile or other desired characteristics. It is clearly advantageous when this repertoire is enlarged by the discovery of new crystalline forms of a useful compound. For a general review of polymorphs and the pharmaceutical applications of polymorphs see G.M. Wall, Pharm Manuf 3, 33 (1986); J.K. Haleblian and W. McCrone, J. Pharm. Sci., 58, 911 (1969); and J.K. Haleblian, J. Pharm. Sci., 64, 1269 (1975), all of which are incorporated herein by reference.

The solid state physical properties of crystalline forms of a pharmaceutically useful salt can be influenced by controlling the conditions under which the salt is obtained in solid form. Solid state physical properties include, for example, the flowability of the milled solid. Flowability affects the ease with which the material is handled during processing into a pharmaceutical product. When particles of the powdered compound do not flow past each other easily, a formulation specialist must take that fact into account in developing a tablet or capsule formulation, which may necessitate the use of glidants such as colloidal silicon dioxide, talc, starch or tribasic calcium phosphate.

Another important solid state property of a pharmaceutical compound is its rate of dissolution in aqueous fluid. The rate of dissolution of an active ingredient in a patient's stomach fluid can have therapeutic consequences since it imposes an upper limit on the rate at which an orally-administered active ingredient can reach the patient's bloodstream. The rate of dissolution is also a consideration in formulating syrups, elixirs and other liquid medicaments. The solid-state form of a compound may also affect its behaviour on compaction and its storage stability.

Regulatory agencies worldwide require a reasonable effort to identify the polymorphs of the drug substance and check for polymorph interconversions. Due to the often-unpredictable behaviour of polymorphs and their respective differences in physicochemical properties, consistency in manufacturing between batches of the same product must be demonstrated. Proper understanding of the polymorph landscape and nature of the polymorphs of a pharmaceutical will contribute to manufacturing consistency.

Consequently, it would be a significant contribution to the art to provide new forms of 4-[3-chloro-4-(cyclopropylaminocarbonyl) aminophenoxy)_7-methoxy-6-quinolinecarboxamide mesylate; having increased solubility, and methods of preparation, pharmaceutical formulations, and methods of use thereof.

DETAILED DESCRIPTION:
As used herein, the term "solvated" is understood to mean formation of a complex of variable stoichiometry comprising 4-(3-chloro-4-(cyclopropyl aminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate of Formula (I) and a solvent. Such solvents for the purpose of the invention may not interfere with the biological activity of the solute. Typically, the solvent used is a pharmaceutically acceptable solvent. Examples of suitable pharmaceutically acceptable solvents include C1-C4 alcohol solvents, benzyl alcohol, 4-methyl pentane 2-one, propylene glycol, acetonitrile and dimethylsulfoxide (DMSO), and solvates of more than 1%.

The solvate can be isolated either as an amorphous form or in a crystalline form, preferably in crystalline form.

The solvate can be further isolated either in anhydrous form or hydrated form.

As used herein, the term "hydrate" is understood as a substance that is formed by adding water molecules. The skilled person will appreciate that the water molecules are absorbed, adsorbed or contained within a crystal lattice of the solid compounds, usually in defined stoichiometric ratio. The notation for a hydrated compound may be .nH2O, where n is the number of water molecules per formula unit of the compound. For example, in a hemihydrate, n is 0.5; in a monohydrate n is one; in a sesquihydrate, n is 1.5; in a dihydrate, n is 2; and so on.

In comparison to the restricted stoichiometric hydrates, non-stoichiometric hydrates can vary in water content without major change in their crystal structure. The amount of water in the crystal lattice only depends on the partial pressure of water in the surrounding atmosphere.

Structurally, non-stoichiometric hydrates normally show channels or networks, through which the water molecules can diffuse. Depending on how the water is arranged inside the crystals, they are classified as isolated hydrates, channel hydrates and ion associated hydrates.

As used herein, the term "substantially the same X-ray powder diffraction pattern" is understood to mean that those X-ray powder diffraction patterns having diffraction peaks with 2? values within ± 0.2° of the diffraction pattern referred to herein are within the scope of the referred to diffraction pattern.

In one aspect the present invention provides novel polymorphic forms of the angiogenesis inhibitor and antitumor agent 4-(3-chloro-4-(cyclopropyl aminocarbonyl) aminophenoxy)-7-methoxy-6-quinolinecarboxamide mesylate. The mesylate may be isolated in pseudo polymorphic form as a solvate optionally in hydrated form, or as a non-hydrated solvate.
Accordingly, pseudo polymorphs provided include solvates, more in particular, C1-C4 alcohol solvates, a benzyl alcohol solvate, a 4-methyl pentane 2-one solvate, a propylene glycol solvate, a acetonitrile solvate and a dimethyl sulfoxide (DMSO) solvate, optionally in hydrated form.

As polymorphic forms are reliably characterized by peak positions in the X-ray diffractogram, the polymorphs of the present invention have been characterized by powder X-ray diffraction spectroscopy which produces a fingerprint of the particular crystalline form. Measurements of 2? values are accurate to within ± 0.2 degrees. All the powder diffraction patterns were measured on a Rigaku Dmax 2200 advanced X-ray powder diffractometer with a copper-K-a radiation source.
