CRIZOTINIB HYDROCHLORIDE SALT IN CRYSTALLINE
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application Nos. 61/652,708, filed May 29, 2012; and 61/752,673; filed January 15, 2013, the contents of which are incorporated herein by reference in their entirety.
FIELD OF THE INVENTION
The present invention encompasses Crizotinib salts, solid state forms thereof, and pharmaceutical compositions comprising the Crizotinib salts and solid state forms thereof.
BACKGROUND OF THE INVENTION
Crizotinib, (i?)-3-[l-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-(l-piperidin-4-yl-lH- pyrazol-4-yl)-pyridin-2-ylamine, having the following formula
Figure imgf000002_0001
is an orally active dual inhibitor of mesenchymal epithelial transition growth factor (c-Met) and anaplastic lymphoma kinase (ALK). It was developed for the treatment of cancer.
Crizotinib, as well as certain pharmaceutically acceptable salts thereof, is described in WO2006/021881 and WO2006/021884. WO2007/066185 describes a crystalline form of the Crizotinib base.
Different salts and solid state forms of an active pharmaceutical ingredient may possess different properties. Such variations in the properties of different salts and solid state forms may provide a basis for improving formulation, for example, by facilitating better processing or handling characteristics, improving the dissolution profile, or improving stability (polymorph as well as chemical stability) and shelf-life. These variations in the properties of different salts and solid state forms may also provide improvements to the final dosage form, for instance, if they serve to improve bioavailability. Different salts and solid state forms of an active pharmaceutical ingredient may also give rise to a variety of polymorphs or crystalline forms, which may in turn provide additional opportunities to assess variations in the properties and characteristics of a solid active pharmaceutical ingredient.
Polymorphism, the occurrence of different crystal forms, is a property of some molecules and molecular complexes. A single molecule may give rise to a variety of polymorphs having distinct crystal structures and physical properties like melting point, thermal behaviors (e.g. measured by thermogravimetric analysis - "TGA", or differential scanning calorimetry - "DSC"), X-ray diffraction pattern, infrared or Raman absorption fingerprint, and solid state 13C-NMR spectrum. One or more of these techniques may be used to distinguish different polymorphic forms of a compound.
Discovering new salts and solid state forms of a pharmaceutical product can provide materials having desirable processing properties, such as ease of handling, ease of processing, storage stability, ease of purification or as desirable intermediate crystal forms that facilitate conversion to other polymorphic forms. New salts and solid state forms (including solvated forms) of a pharmaceutically useful compound can also provide an opportunity to improve the performance characteristics of a pharmaceutical product (dissolution profile,
bioavailability, etc.). It enlarges the repertoire of materials that a formulation scientist has available for formulation optimization, for example by providing a product with different properties, e.g., different crystal habit, higher crystallinity or polymorphic stability which may offer better processing or handling characteristics, improved dissolution profil, or improved shelf-life. For at least these reasons, there is a need for additional salts and solid state forms of Crizotinib.

In some embodiments, salts and solid state forms of Crizotinib of the invention are substantially free of any other salts, polymorphic forms, or of specified polymorphic forms of Crizotinib, respectively. In any embodiment of the present invention, by "substantially free" is meant that the forms of the present invention contain 20% (w/w) or less, 10% (w/w) or less, 5% (w/w) or less, 2% (w/w) or less, particularly 1% (w/w) or less, more particularly 0.5% (w/w) or less, and most particularly 0.2% (w/w) or less of any other salts, polymorphs or of a specified polymorph of Crizotinib. In other embodiments, the salts and solid state forms of Crizotinib phosphate, Crizotinib sulphate, Crizotinib acetate, Crizotinib maleate, Crizotinib fumarate, Crizotinib L-tartrate, Crizotinib citrate, Crizotinib p-toluene sulfonate, Crizotinib succinate, Crizotinib formate Crizotinib hydrochloride, Crizotinib besilate, Crizotinib ethane- 1.2-disulfonate and Crizotinib L-malate of the invention contain from 1% to 20% (w/w), from 5% to 20% (w/w), or from 5% to 10% (w/w) of any other salts, solid state forms or of a specified polymorph of Crizotinib.
Depending on which other salt or solid state form they are compared with, the Crizotinib salts and solid state forms thereof of the present invention (particularly, phosphate, sulphate, acetate, maleate, fumarate, L-tartrate, citrate, p-toluene sulfonate, succinate, formate, hydrochloride, besilate, ethane- 1.2-disulfonate and L-malate salts) have advantageous properties selected from at least one of: chemical purity, flowability, solubility, dissolution rate, morphology or crystal habit, stability (such as thermal and mechanical stability to polymorphic conversion, stability to dehydration and/or storage stability), low content of residual solvent, a lower degree of hygroscopicity, and advantageous processing and handling characteristics such as flowability, filterability compressibility, and bulk density.
A crystal form may be referred to herein as being characterized by graphical data "as depicted in" or "as substantially depicted in" a Figure. Such data include, for example, powder X-ray diffractograms and solid state NMR spectra. As is well-known in the art, the graphical data potentially provides additional technical information to further define the respective solid state form (a so-called "fingerprint") which cannot necessarily be described by reference to numerical values or peak positions alone. In any event, the skilled person will understand that such graphical representations of data may be subject to small variations, e.g., in peak relative intensities and peak positions due to factors such as variations in instrument response and variations in sample concentration and purity, which are well known to the skilled person. Nonetheless, the skilled person would readily be capable of comparing the graphical data in the Figures herein with graphical data generated for an unknown crystal form and confirm whether the two sets of graphical data are characterizing the same crystal form or two different crystal forms. A crystal form of a Crizotinib salt referred to herein as being characterized by graphical data "as depicted in" or "as substantially depicted in" a Figure will thus be understood to include any crystal forms of the Crizotinib salts
characterized with the graphical data having such small variations, as is well-known to the skilled person, in comparison with the Figure.
As used herein, the term "isolated" in reference to any of Crizotinib salts or solid state forms thereof of the present invention corresponds to Crizotinib salts or solid state forms thereof that is physically separated from the reaction mixture where the salts or solid state forms were formed. As used herein the term non-hygroscopic in relation to any of the salts and solid state forms of Crizotinib refers to less than 2% (w/w) adsorption of water, by the salt or solid state form of Crizotinib as determined, for example by TGA. Water can be, for example, atmospheric water.
As used herein, unless stated otherwise, the XRPD measurements are taken using copper Ka radiation wavelength 1.5406 A.
Solid state forms of Crizotinib comprise crystal forms, or crystalline forms, of Crizotinib. As used herein, solid state forms, crystal forms, crystalline forms, polymorphs and polymorphic forms are used interchangeably.
As used herein, and unless stated otherwise, the term "anhydrous" in relation to any of the crystalline Crizotinib salts relates to a crystalline Crizotinib salt which contains not more than 1.5% (w/w), or not more than 1% (w/w) of either water or organic solvents (bound and unbound) as measured by TGA or by Karl Fischer titration, for example, a Crizotinib salt which contains between about 0% to about 1.5% (w/w) or between about 0% to about 1% (w/w) of either water or organic solvents as measured by TGA or by Karl Fischer titration.
As used herein and unless indicated otherwise, the term "solvate" refers to a crystal form that incorporates a solvent in the crystal structure. When the solvent is water, the solvate is often referred to as a "hydrate." The solvent in a solvate may be present in either a stoichiometric or in a non-stoichiometric amount.
A thing, e.g., a reaction mixture, may be characterized herein as being at, or allowed to come to "room temperature", often abbreviated " T." This means that the temperature of the thing is close to, or the same as, that of the space, e.g., the room or fume hood, in which the thing is located. Typically, room temperature is from about 20°C to about 30°C, or about 22°C to about 27°C, or about 25°C.
A process or step may be referred to herein as being carried out "overnight." This refers to a time interval, e.g., for the process or step, that spans the time during the night, when that process or step may not be actively observed. This time interval is from about 8 to about 20 hours, or about 10-18 hours, typically about 16 hours.
As used herein, the term "reduced pressure" refers to a pressure of about 10 mbar to about 50 mbar.
As used herein, the terms "vol." or "volume" can be used to refer to ml per gram of the corresponding Crizotinib. For example, a statement that 0.5 g of Crizotinib is dissolved in ten volumes of a Solvent X would be understood to mean that the 0.5 g of Crizotinib was dissolved in 5 ml of Solvent X.
The present invention comprises salts of Crizotinib, in particular: phosphate, sulphate, acetate, maleate, fumarate, L-tartrate, citrate, p-toluene sulfonate, succinate, formate, hydrochloride, besylate, ethane- 1.2-disulfonate and L-malate salts. The above salts can be isolated.
