Description

SOLID STATE FORM OF PIRTOBRUTINIBFIELD OF THE DISCLOSURE

[0001] The present disclosure encompasses a solid state form of Pirtobrutinib.BACKGROUND OF THE DISCLOSURE

[0002] Pirtobrutinib, 5-amino-3-[4-[[(5-fluoro-2-methoxybenzoyl)amino]methyl]phenyl]-l- [(25)-l,l,l-trifluoropropan-2-y1]pyrazole-4-carboxamide, has the following chemical structure:

[0003] Pirtobrutinib is indicated for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a BTK inhibitor. Pirtobrutinib is under clinical investigation for the treatment of various cancers, particularly B-cell malignancies, such as B-cell lymphomas and B-cell leukemias, for example relapsed or refractory mantle cell lymphoma (MCL), chronic lymphocytic leukemia, small lymphocytic lymphoma, Waldenstrom's macroglobulinemia, Richter’s transformation (Richter’s syndrome), and marginal zone lymphoma.

[0004] The compound is described in International Publication No. WO 2017 / 103611. Crystalline forms of Pirtobrutinib are described in International Publication Nos. WO 2020 / 028258 and WO 2022 / 240920. International Publication No. WO 2022 / 056100 describes a process for preparation of Pirtobrutinib.

[0005] Polymorphism, the occurrence of different crystalline 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 (XRD) pattern, infrared absorption fingerprint, and solidstate (13C) NMR spectrum. One or more of these techniques may be used to distinguish different polymorphic forms of a compound.

[0006] Different salts and solid state forms (including solvated forms) of an active pharmaceutical ingredient may possess different properties. Such variations in the properties of different salts and solid state forms and solvates may provide a basis for improving formulation, for example, by facilitating better processing or handling characteristics, changing the dissolution profile in a favorable direction, 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 offer improvements to the final dosage form, for instance, if they serve to improve bioavailability. Different salts and solid state forms and solvates 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.

[0007] Discovering new solid state forms and solvates of a pharmaceutical product may yield materials having desirable processing properties, such as ease of handling, ease of processing, storage stability, and ease of purification or as desirable intermediate crystal forms that facilitate conversion to other polymorphic forms. New solid state forms of a pharmaceutically useful compound can also provide an opportunity to improve the performance characteristics of a pharmaceutical product. It enlarges the repertoire of materials that a formulation scientist has available for formulation optimization, for example by providing a product with different properties, including a different crystal habit, higher crystallinity, or polymorphic stability, which may offer better processing or handling characteristics, improved dissolution profile, or improved shelf-life (chemical / physical stability). For at least these reasons, there is a need for additional solid state forms (including solvated forms) of Pirtobrutinib.SUMMARY OF THE DISCLOSURE

[0036] The present disclosure encompasses a crystalline form of Pirtobrutinib, processes for preparation thereof, and pharmaceutical compositions thereof.

[0037] Solid state properties of Pirtobrutinib and crystalline polymorphs thereof can be influenced by controlling the conditions under which Pirtobrutinib and crystalline polymorphs thereof are obtained in solid form.

[0038] The solid state forms of Pirtobrutinib as described in any aspect or embodiment of the present disclosure may be polymorphically pure, or substantially free of any other solid state (or polymorphic) forms.

[0039] A solid state form (or polymorph) may be referred to herein as polymorphically pure or as substantially free of any other solid state (or polymorphic) forms. As used herein in this context, the expression "substantially free of any other forms" will be understood to mean that the solid state form contains about 20% (w / w) or less, about 10% (w / w) or less, about 5% (w / w) or less, about 2% (w / w) or less, about 1% (w / w) or less, or about 0% of any other forms of the subject compound as measured, for example, by XRPD. For example, polymorphically pure Pirtobrutinib Form 2 means that the solid state form is substantially free of other solid state forms of Pirtobrutinib. Thus, a crystalline polymorph of Pirtobrutinib described herein as substantially free of any other solid state forms would be understood to contain greater than about 80% (w / w), greater than about 90% (w / w), greater than about 95% (w / w), greater than about 98% (w / w), greater than about 99% (w / w), or about 100% of the subject crystalline polymorph of Pirtobrutinib. In some embodiments of the disclosure, the described crystalline polymorph of Pirtobrutinib, salt or cocrystal may contain from about 1% to about 20% (w / w), from about 5% to about 20% (w / w), or from about 5% to about 10% (w / w) of one or more other crystalline polymorph of the same Pirtobrutinib.

[0040] Depending on which other crystalline polymorphs a comparison is made, the crystalline polymorphs of Pirtobrutinib of the present disclosure may have advantageousproperties selected from at least one of the following: chemical purity, flowability, solubility, dissolution rate, morphology or crystal habit, stability, such as chemical stability as well as thermal and mechanical stability with respect to polymorphic conversion, stability towards dehydration and / or storage stability, low content of residual solvent, a lower degree of hygroscopicity, flowability, and advantageous processing and handling characteristics such as compressibility and bulk density.

[0041] A solid state form, such as a crystal form or an amorphous 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 certain factors such as, but not limited to, 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 Pirtobrutinib 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 Pirtobrutinib characterized with the graphical data having such small variations, as are well known to the skilled person, in comparison with the Figure.

[0042] As used herein, and unless stated otherwise, the term “anhydrous” in relation to crystalline forms of Pirtobrutinib relates to a crystalline form of Pirtobrutinib which does not include any crystalline water (or other solvents) in a defined, stoichiometric amount within the crystal. Moreover, an “anhydrous” form would generally not contain more than 1% (w / w), of either water or organic solvents as measured for example by TGA.

[0043] The term "solvate," as used herein and unless indicated otherwise, refers to a crystal form that incorporates a solvent in the crystal structure. When the solvent is water, the solvate isoften referred to as a "hydrate." The solvent in a solvate may be present in either a stoichiometric or in a non-stoichiometric amount.

[0044] As used herein, unless stated otherwise, unit cell data were obtained by solving the crystal structure, unit cell data is preferably measured at 298K.

[0045] As used herein, the term "isolated" in reference to crystalline polymorph of Pirtobrutinib of the present disclosure corresponds to a crystalline polymorph of Pirtobrutinib that is physically separated from the reaction mixture in which it is formed.

[0046] As used herein, unless stated otherwise, the XRPD measurements are taken using copper K a radiation wavelength 1.541874 A. XRPD peaks reported herein are optionally measured using CuK a radiation, X = 1.541874 A, typically at a temperature of 25 ± 3°C.

[0047] As used herein, unless stated otherwise,13C NMR reported herein are measured at 16.4 T at a magic angle spinning frequency ®r / 27t = 20 kHz, preferably at a temperature of 298 K ± 3°K.

[0049] As used herein, and unless stated otherwise, the term Pirtobrutinib Premix refers to a solid dispersion of Pirtobrutinib with a pharmaceutically acceptable carrier, and optionally other pharmaceutically acceptable excipients. Such a solid dispersion can be a co-precipitate of Pirtobrutinib with a pharmaceutically acceptable carrier, and optionally other pharmaceutically acceptable excipients. Such a co-precipitate may be prepared by mixing crystalline form 2 of Pirtobrutinib and a pharmaceutically acceptable carrier and optionally other pharmaceutically acceptable excipients in a suitable solvent(s) to form a mixture, and removing the solvent(s) from the mixture. The mixture may be a solution (e.g. wherein the components are dissolved), or a suspension or dispersion (e.g. wherein none of the components are dissolved but form a suspension or dispersion, or wherein some but not all of the components are dissolved). The solvent may be removed from the mixture by techniques such as spray drying, lyophilization or evaporation. Suitable pharmaceutically acceptable carriers for preparing the solid dispersion include pharmaceutically acceptable polymeric carriers, including polyvinylpyrrolidone (PVP), copovidone (copolymer of 1 -vinyl-2-pyrrolidone and vinyl acetate), polyethylene glycol, hydroxypropylmethyl cellulose (hypromellose, HPMC), and hydroxylpropylmethyl celluloseacetate succinate, HPMCAS).

For example, aliphatic alcohols (such as methanol, ethanol and isopropanol), ethers (such as diethyl ether and tetrahydrofuran), ketones (such as acetone) and esters (such as ethylacetate), and water, or mixtures thereof, may be used.

[0051] As used herein the term "spray-drying" refers to the method of producing a dry powder from a solution or slurry. The solution or slurry is for example atomized or rapidly dried with a hot gas, e.g., air or nitrogen, that causes the solvent to evaporate quickly and uniformly.

[0052] Preferably, according to any aspect or embodiment, the Pirtobrutinib premix is a spray-dried dispersion of Pirtobrutinib.

[0082] The present disclosure also encompasses the use of crystalline polymorph of Pirtobrutinib of the present disclosure for the preparation of pharmaceutical compositions of crystalline polymorph Pirtobrutinib and / or solid state forms thereof.

[0083] The present disclosure includes processes for preparing the above mentioned pharmaceutical compositions. The processes include combining any one or a combination of the crystalline polymorph of Pirtobrutinib of the present disclosure with at least one pharmaceutically acceptable excipient.

[0084] Pharmaceutical combinations or formulations of the present disclosure contain any one or a combination of the solid state form of Pirtobrutinib of the present disclosure. In addition to the active ingredient, the pharmaceutical formulations of the present disclosure can contain one or more excipients. Excipients are added to the formulation for a variety of purposes.

[0091] Solid and liquid compositions can also be dyed using any pharmaceutically acceptable colorant to improve their appearance and / or facilitate patient identification of the product and unit dosage level.

[0092] In liquid pharmaceutical compositions of the present invention, Pirtobrutinib and any other solid excipients can be dissolved or suspended in a liquid carrier such as water, vegetable oil, alcohol, polyethylene glycol, propylene glycol, or glycerin.

[0093] Liquid pharmaceutical compositions can contain emulsifying agents to disperse uniformly throughout the composition an active ingredient or other excipient that is not soluble in the liquid carrier. Emulsifying agents that can be useful in liquid compositions of the present invention include, for example, gelatin, egg yolk, casein, cholesterol, acacia, tragacanth, chondrus, pectin, methyl cellulose, carbomer, cetostearyl alcohol, and cetyl alcohol.

[0095] Sweetening agents such as sorbitol, saccharin, sodium saccharin, sucrose, aspartame, fructose, mannitol, and invert sugar can be added to improve the taste.

[0096] Preservatives and chelating agents such as alcohol, sodium benzoate, butylated hydroxyl toluene, butylated hydroxyanisole, and ethylenediamine tetraacetic acid can be added at levels safe for ingestion to improve storage stability.

[0097] According to the present disclosure, a liquid composition can also contain a buffer such as gluconic acid, lactic acid, citric acid, or acetic acid, sodium gluconate, sodium lactate, sodium citrate, or sodium acetate. Selection of excipients and the amounts used can be readily determined by the formulation scientist based upon experience and consideration of standard procedures and reference works in the field.

[0098] The solid compositions of the present disclosure include powders, granulates, aggregates, and compacted compositions.

Although the most suitable administration in any given case will depend on the nature and severity of the condition being treated, in embodiments the route of administration is oral. The dosages can be conveniently presented in unit dosage form and prepared by any of the methods well-known in the pharmaceutical arts.

[0099] Dosage forms include solid dosage forms like tablets, powders, capsules, suppositories, sachets, troches, and lozenges, as well as liquid syrups, suspensions, and elixirs.

[0100] The dosage form of the present disclosure can be a capsule containing the composition, such as a powdered or granulated solid composition of the disclosure, within either a hard or soft shell. The shell can be made from gelatin and optionally contain a plasticizer such as glycerin and / or sorbitol, an opacifying agent and / or colorant.

[0101] The active ingredient and excipients can be formulated into compositions and dosage forms according to methods known in the art.

[0102] A composition for tableting or capsule filling can be prepared by wet granulation. In wet granulation, some or all of the active ingredients and excipients in powder form are blended and then further mixed in the presence of a liquid, typically water that causes the powders to clump into granules. The granulate is screened and / or milled, dried, and then screened and / or milled to the desired particle size. The granulate can then be tableted, or other excipients can be added prior to tableting, such as a glidant and / or a lubricant.

[0103] A tableting composition can be prepared conventionally by dry blending. For example, the blended composition of the actives and excipients can be compacted into a slug or a sheet and then comminuted into compacted granules. The compacted granules can subsequently be compressed into a tablet.

[0104] As an alternative to dry granulation, a blended composition can be compressed directly into a compacted dosage form using direct compression techniques. Direct compression produces a more uniform tablet without granules. Excipients that are particularly well suited for direct compression tableting include microcrystalline cellulose, spray dried lactose, dicalcium phosphate dihydrate, and colloidal silica. The proper use of these and other excipients in direct compression tableting is known to those in the art with experience and skill in particular formulation challenges of direct compression tableting.

[0105] A capsule filling of the present disclosure can include any of the aforementioned blends and granulates that were described with reference to tableting, but they are not subjected to a final tableting step.

[0106] A pharmaceutical formulation of Pirtobrutinib can be administered. Pirtobrutinib may be formulated for administration to a mammal, in embodiments to a human, by injection. Pirtobrutinib can be formulated, for example, as a viscous liquid solution or suspension, such asa clear solution, for injection. The formulation can contain one or more solvents. A suitable solvent can be selected by considering the solvent's physical and chemical stability at various pH levels, viscosity (which would allow for syringeability), fluidity, boiling point, miscibility, and purity. Suitable solvents include alcohol USP, benzyl alcohol NF, benzyl benzoate USP, and Castor oil USP. Additional substances can be added to the formulation such as buffers, solubilizers, and antioxidants, among others. Ansel et al., Pharmaceutical Dosage Forms and Drug Delivery Systems, 7th ed.

[0135] Pirtobrutinib obtained according to Example 3, Procedure I (15.0 grams, 31 mmol) was charged in a 250 ml reactor and suspended in distilled water (150 ml, 10 V / w). The off- white suspension was stirred overnight at room temperature and then filtered. The off white crystals were washed two times with distilled water (2 x 75 ml, 2 x 5 V / w). The solids were collected and dried for 10 h at 50 °C and 10 mbar to obtain Pirtobrutinib form 2 (HPLC purity 98.77%).Procedure K

[0136] Pirtobrutinib (amorphous, about 150-200 mg), obtained according to example 3, Procedure A was suspended in water (about 1.5-2.5 ml) and slurried at room temperature for period of about 5 days. Solid matter was filtered, dried under vacuum and analyzed by XRPD, DSC and TGA. Form 2 was obtained.Example 4 - Compressibility Determination

[0137] A die and a flat-faced punch fitted on a TA-XTplus Texture analyser (FA 5029767, Stable Micro Systems Ltd., Godaiming, UK) was used. 200 mg of the test sample were compressed in a steel mould (with the rate of displacement 0.03 mm / s).

[0138] In addition, a cyclic procedure (similar to tapping) was performed in 10 compressive force steps of in increments of 1 kg, force relaxation for 10 s then retracting to zero, and then repeated compressive steps (altogether up to 10 steps). The data is presented in the table below:Carr index for Pirtobrutinib forms 2 and A

[0139] A high Carr’s Index is indicative of poorer flowability. In particular, a material having a Carr’s Index of 26 or greater is considered to show poor flowability, and a material having a Carr’s Index of 32-37 is classified as having a very poor flowability. Form A has a Carr’s Index of 34, which is classified as having very poor flowability. In contrast, the Form 2 has a significantly lower Carr’s Index (17.84) and hence has a superior flowability compared to Form A.Example 5 - Solubility

[0140] The solubilities of Pirtobrutinib forms 2 and Pirtobrutinib form A were determined in water, pH 4.5 buffer, pH 6.8 buffer and pH 1.2 solution as follows:Buffers and solutions were prepared as follows:HC1 solution, pH= 1.2

[0141] 16.6 mL of cone. Hydrochloric acid (12 M) was added to 2 L of water.Acetate buffer, pH 4.5

[0142] 2.99 grams of sodium acetate trihydrate buffer was weighed in 1000 mL beaker, dissolved in about 500 ml of purified water, and 14 mL of 2.0 N Acetic acid solution in 1000 mLbeaker was added, then diluted to lOOOmL with purified water. pH value 4.50 ± 0.05 is measured or adjusted using 2.0 N acetic acid solution.Phosphate buffer, pH=6.80

[0143] 250 mL of 0.2M Potassium phosphate buffer and 112 mb of 0.2M Sodium hydroxide solution were mixed in 1000 mL beaker, diluted up-to mark with purified water. pH value 6.80 ± 0.05 is measured or adjusted with 0.2 M Sodium hydroxide solution.

[0144] Pirtobrutinib samples (around 50 mg) were weighed into 15 ml TPP centrifuge tubes (Sigma) and 11 ml of solvent was added. Solvents used were water, phosphate buffer (pH=6.8), acetate buffer (pH= 4.5) and hydrochloric acid solution (pH= 1.2).

[0145] Tubes were stoppered and shaken at 160 rpm for 24 hours at 37±0.2 °C in incubator shaker (Innova 4080, New Brunswick Scientific). Suspensions were filtered through 0.45 pm PTFE syringe filter and Pirtobrutinib concentrations were determined by HPLC. Obtained results are shown in the table below:Solubility comparison of form A and Form 2 after 1 hour.

[0146] The results show that the Pirtobrutinib form 2 has a significantly higher solubility in all the tested media compared with Form A. The higher solubility is particularly advantageous from the point of view of processing the active agent to prepare a pharmaceutical composition or formulation. Moreover, a higher solubility is associated with better pharmacokinetic characteristics and drug absorption.
