Definitions

  • the invention relates to a pharmaceutical dosage form comprising Empagliflozin in the form of an amorphous solid solution with at least one polymer, as well as to a process for the preparation thereof.
  • the pharmaceutical dosage form exhibits excellent chemical and physical storage stability.
  • Empagliflozin is a white to yellowish non-hygroscopic crystalline solid, very slightly soluble in water (pH 1-7.4), slightly soluble in acetonitrile and ethanol, sparingly soluble in methanol, and practically insoluble in toluene.
  • Empagliflozin is an orally administered selective sodium-dependent glucose co-transporter 2 (SGLT 2) inhibitor.
  • the sodium-dependent glucose co-transporter 2 (SGLT 2) is expressed in the renal proximal tubules and accounts for approximately 90% of renal glucose reabsorption. Inhibition of SGLT 2 decreases the renal reabsorption of glucose, thereby promoting glucose excretion in the urine with a consequent reduction in blood glucose levels. Due to their mainly insulin-independent mechanism of action, SGLT 2 inhibitors may have a low risk of hypoglycaemia. Further effects of SGLT 2 inhibition may include weight loss due to the calorie loss associated with increased glucose excretion and a reduction in blood pressure that is possibly due to a mild diuretic effect.
  • Empagliflozin is used for improvement of glycemic control in adults with type 2 diabetes mellitus and for reducing the risk of cardiovascular death in adult patients with type 2 diabetes mellitus and established cardiovascular disease.
  • Empagliflozin is available on the market in the form of a free base and is sold under trade name Jardiance ® , as an oral tablet in 10 mg and 25 mg strengths. Further it is available on the market as a combination product with Metformin and a combination product with Linagliptin.
  • EP 1 730 131 discloses Empagliflozin, process for production thereof, its use and pharmaceutical composition thereof.
  • the composition of a tablet is disclosed that comprises active ingredient in admixture with non-toxic pharmaceutically acceptable excipients, such as lactose, com starch, polyvinylpyrrolidone, magnesium stearate.
  • EP 1 888 551 and EP 1 888 552 disclose specific crystalline forms of Empagliflozin, methods for production thereof and synthesis of Empagliflozin.
  • EP 3 556 355 discloses a method of preparation of Empagliflozin in amorphous form by spray drying.
  • the thus prepared Empagliflozin is in the form of particles with pharmaceutically acceptable polymer, and can be used in the treatment or prevention of type 2 diabetes.
  • WO 2010/092126 discloses pharmaceutical dosage form of Empagliflozin wherein particle size distribution of Empagliflozin in the composition is D(90) >1 micron and D(90) ⁇ 200 micron and wherein Empagliflozin represents 25% or less of the weight of the composition.
  • Pharmaceutical compositions are disclosed that comprise lactose, microcrystalline cellulose, croscarmellose sodium as a disintegrant, hydroxypropyl cellulose as a binder, silicon dioxide as a glidant and magnesium stearate as a lubricant. These excipients are similar to those present in the marketed formulation of Empagliflozin.
  • the particle size of Empagliflozin in particular the particle size and the particle size distribution, influence the manufacturability, in particular that too small particles, especially too many small particles, negatively influence the manufacturability by sticking or filming during tableting.
  • too small particles especially too many small particles, negatively influence the manufacturability by sticking or filming during tableting.
  • too large particles negatively affect the dissolution properties of the pharmaceutical composition and dosage form and thus the bioavailability.
  • WO 2016/169534 discloses amorphous solid forms of Empagliflozin stabilized in the form of solid solutions with pharmaceutically acceptable excipient selected from the group consisting of polymers, saccharides, oligosaccharides, polysaccharides, fats, waxes and urea.
  • a preferred excipient is such wherein the final composition achieves a glass transition temperature higher than 40 °C, even better higher than 70 °C.
  • Preferred excipients are especially hydroxypropyl cellulose, hydroxypropyl methylcellulose, hypromellose acetate succinate, povidone PVP K30, SoluplusTM, PEG 6000 or copovidone VA64.
  • stabilized amorphous substances can be prepared by solvent-free processes, wherein a mixture of Empagliflozin and a stabilizing polymer is heated and melted to obtain a melt, which is subsequently cooled down to produce amorphous solid substance.
  • processes can be hot melt extrusion, hot melt granulation, high shear mixer, solvent free fluid bed granulation.
  • CN 106 692 069 discloses an Empagliflozin solid dispersion preparation and a preparation method thereof.
  • the Empagliflozin solid dispersion preparation comprises Empagliflozin, povidone, a specific lubricant and a specific disintegrant and a diluent.
  • amorphous solid dispersions are disclosed which are prepared by dissolving Empagliflozin and polymer in methanol and spray drying the solution using spray drier.
  • compositions comprising active substance Empagliflozin in amorphous form.
  • Exemplified pharmaceutical compositions are prepared by dissolving Empagliflozin and povidone in a mixture of methylene chloride and ethanol, spraying of the prepared solution on pharmaceutically acceptable carrier to obtain granules, blending the granules with further excipients, lubricating the mixture and compressing into tablets.
  • the document discloses very broad range of possible ratios of Empagliflozin to polymer, which acts as a binder which varies form 1 :0.025 to 1 :4. Consequently Empagliflozin may be present in crystalline form or in amorphous form.
  • compositions comprising Empagliflozin.
  • the disclosed compositions comprise Empagliflozin in crystalline form wherein particle size must be carefully controlled, or in amorphous form wherein amorphous form is stabilized by preparing solid dispersions or solid solutions by processes such as evaporating the solvent by rotary evaporator or by lyophilization. These procedures are not convenient to be used on industrial scale. Furthermore, methylene chloride was used as a solvent which has several drawbacks when used in industrial scale.
  • amorphous solid dispersions as prepared by the prior art processes were intermediate products which have to be further processed into a pharmaceutical composition requiring processes such as milling, sieving, mixing with further inactive ingredients, granulating before compressing into the tablets. These processes are time consuming and are disadvantageous from economical point of view.
  • Methylene chloride and methanol are classified as Class 2 solvents; such solvents should be limited in pharmaceutical products because of their inherent toxicity.
  • the limit for residual solvent is 600 ppm for methylene chloride and 3000 ppm for methanol.
  • Halogenated solvents are carcinogenic or are suspected to be carcinogenic and such solvent should be used under strict conditions during technological process, requiring special conditions to prevent exposure of workers to the solvent. These solvent are not allowed to be released into environment and should be insinuated e.g. by pyrolysis, such measures increase the production cost.

Abstract

The invention provides solid pharmaceutical dosage forms and methods for making the same, wherein the pharmaceutical dosage forms comprise Empagliflozin in the form of an amorphous solid solution with at least one polymer. The pharmaceutical dosage forms according to the invention exhibit excellent stability especially in terms of physical stabilization of amorphous form of Empagliflozin.

Description

Dosage Form Comprising Amorphous Solid Solution Of Empagliflozin With Polymer
[0001] Priority is claimed of European patent application no. 19 218 238 that was filed on December 19, 2019.
[0002] The invention relates to a pharmaceutical dosage form comprising Empagliflozin in the form of an amorphous solid solution with at least one polymer, as well as to a process for the preparation thereof. The pharmaceutical dosage form exhibits excellent chemical and physical storage stability.
[0003] Empagliflozin is a common name for (lS)-l,5-anhydro-l-(4-chloro-3-{4-[(3S)-tetrahydrofuran-3- yloxy]benzyl}phenyl)-D-glucitol, also known as D-Glucitol,l,5-anhydro-l-C-[4-chloro-3-[[4-[[(3S)-tetrahydro- 3-furanyl]oxy]phenyl]methyl]phenyl]-(lS), and has the following structure:
Figure imgf000002_0001
(I).
[0004] Empagliflozin is a white to yellowish non-hygroscopic crystalline solid, very slightly soluble in water (pH 1-7.4), slightly soluble in acetonitrile and ethanol, sparingly soluble in methanol, and practically insoluble in toluene.
[0005] In EMA’s (European Medicines Agency) Public Assessment Report for Jardiance® it is disclosed that Empagliflozin is very slightly soluble in aqueous media between pH 1-7.5 and has low intestinal permeability, therefore it was classified according to BCS in class III. Further it is disclosed that particle size was not found to be critical for dissolution, but since coarser API dissolves slightly more slowly, the API substance is milled and particle size is tightly controlled.
[0006] Empagliflozin is an orally administered selective sodium-dependent glucose co-transporter 2 (SGLT 2) inhibitor. The sodium-dependent glucose co-transporter 2 (SGLT 2) is expressed in the renal proximal tubules and accounts for approximately 90% of renal glucose reabsorption. Inhibition of SGLT 2 decreases the renal reabsorption of glucose, thereby promoting glucose excretion in the urine with a consequent reduction in blood glucose levels. Due to their mainly insulin-independent mechanism of action, SGLT 2 inhibitors may have a low risk of hypoglycaemia. Further effects of SGLT 2 inhibition may include weight loss due to the calorie loss associated with increased glucose excretion and a reduction in blood pressure that is possibly due to a mild diuretic effect. [0007] Empagliflozin is used for improvement of glycemic control in adults with type 2 diabetes mellitus and for reducing the risk of cardiovascular death in adult patients with type 2 diabetes mellitus and established cardiovascular disease.
[0008] Empagliflozin is available on the market in the form of a free base and is sold under trade name Jardiance®, as an oral tablet in 10 mg and 25 mg strengths. Further it is available on the market as a combination product with Metformin and a combination product with Linagliptin.
[0009] EP 1 730 131 discloses Empagliflozin, process for production thereof, its use and pharmaceutical composition thereof. The composition of a tablet is disclosed that comprises active ingredient in admixture with non-toxic pharmaceutically acceptable excipients, such as lactose, com starch, polyvinylpyrrolidone, magnesium stearate.
[0010] EP 1 888 551 and EP 1 888 552 disclose specific crystalline forms of Empagliflozin, methods for production thereof and synthesis of Empagliflozin.
[0011] EP 3 556 355 discloses a method of preparation of Empagliflozin in amorphous form by spray drying. The thus prepared Empagliflozin is in the form of particles with pharmaceutically acceptable polymer, and can be used in the treatment or prevention of type 2 diabetes.
[0012] WO 2010/092126 discloses pharmaceutical dosage form of Empagliflozin wherein particle size distribution of Empagliflozin in the composition is D(90) >1 micron and D(90) <200 micron and wherein Empagliflozin represents 25% or less of the weight of the composition. Pharmaceutical compositions are disclosed that comprise lactose, microcrystalline cellulose, croscarmellose sodium as a disintegrant, hydroxypropyl cellulose as a binder, silicon dioxide as a glidant and magnesium stearate as a lubricant. These excipients are similar to those present in the marketed formulation of Empagliflozin. It is disclosed that the particle size of Empagliflozin, in particular the particle size and the particle size distribution, influence the manufacturability, in particular that too small particles, especially too many small particles, negatively influence the manufacturability by sticking or filming during tableting. On the other hand, too large particles negatively affect the dissolution properties of the pharmaceutical composition and dosage form and thus the bioavailability.
[0013] WO 2016/169534 discloses amorphous solid forms of Empagliflozin stabilized in the form of solid solutions with pharmaceutically acceptable excipient selected from the group consisting of polymers, saccharides, oligosaccharides, polysaccharides, fats, waxes and urea. A preferred excipient is such wherein the final composition achieves a glass transition temperature higher than 40 °C, even better higher than 70 °C. Preferred excipients are especially hydroxypropyl cellulose, hydroxypropyl methylcellulose, hypromellose acetate succinate, povidone PVP K30, Soluplus™, PEG 6000 or copovidone VA64. For the preparation of the amorphous solid forms of Empagliflozin by dissolution process the method of removing the solvent by means of a rotary vacuum evaporator or lyophilization (freeze-drying of solvents) was used. All exemplified processes for preparing solid solutions uses a mixture of methylene chloride and alcohol as a solvent for dissolution and then use rotary vacuum evaporator or lyophilization for removing the solvent to obtain solid solution of Empagliflozin and a polymer. Alternatively, stabilized amorphous substances can be prepared by solvent-free processes, wherein a mixture of Empagliflozin and a stabilizing polymer is heated and melted to obtain a melt, which is subsequently cooled down to produce amorphous solid substance. Such processes can be hot melt extrusion, hot melt granulation, high shear mixer, solvent free fluid bed granulation.
[0014] IN 2013 MU 01985, CN 106 880 595 and WO 2017/203457 disclose solid dispersions containing amorphous Empagliflozin. The processes disclosed in these documents comprise step of dissolving Empagliflozin and pharmaceutically acceptable carrier in a solvent an then removing the solvent by evaporation, flash evaporation, simple evaporation, rotational drying, spray drying, agitated thin-film drying, agitated nutsche filter drying, pressure nutsche filter drying, freeze-drying and filtration and then finally recovering an amorphous solid dispersion comprising Empagliflozin. All exemplified examples comprise a step of evaporation of a solvent using rotary vacuum evaporator.
[0015] CN 106 692 069 discloses an Empagliflozin solid dispersion preparation and a preparation method thereof. The Empagliflozin solid dispersion preparation comprises Empagliflozin, povidone, a specific lubricant and a specific disintegrant and a diluent.
[0016] In WO 2016/051368 amorphous solid dispersions are disclosed which are prepared by dissolving Empagliflozin and polymer in methanol and spray drying the solution using spray drier.
[0017] IN 2017/11026696 discloses pharmaceutical composition comprising active substance Empagliflozin in amorphous form. Exemplified pharmaceutical compositions are prepared by dissolving Empagliflozin and povidone in a mixture of methylene chloride and ethanol, spraying of the prepared solution on pharmaceutically acceptable carrier to obtain granules, blending the granules with further excipients, lubricating the mixture and compressing into tablets. The document discloses very broad range of possible ratios of Empagliflozin to polymer, which acts as a binder which varies form 1 :0.025 to 1 :4. Consequently Empagliflozin may be present in crystalline form or in amorphous form.
[0018] As evident from the prior art and the literature there are reported several pharmaceutical compositions comprising Empagliflozin. The disclosed compositions comprise Empagliflozin in crystalline form wherein particle size must be carefully controlled, or in amorphous form wherein amorphous form is stabilized by preparing solid dispersions or solid solutions by processes such as evaporating the solvent by rotary evaporator or by lyophilization. These procedures are not convenient to be used on industrial scale. Furthermore, methylene chloride was used as a solvent which has several drawbacks when used in industrial scale. The amorphous solid dispersions as prepared by the prior art processes were intermediate products which have to be further processed into a pharmaceutical composition requiring processes such as milling, sieving, mixing with further inactive ingredients, granulating before compressing into the tablets. These processes are time consuming and are disadvantageous from economical point of view. [0019] Pharmaceutical products should contain no higher levels of residual solvents than can be supported by safety data. Commonly used solvents have been grouped by toxicity under the ICH Q3C guidance. The most toxic solvents (Class 1) should be avoided in the production of API substances, excipients, or API products unless their use can be strongly justified in a risk-benefit assessment. Some solvents associated with less severe toxicity (Class
2) should be limited in order to protect patients from potential adverse effects. Ideally, less toxic solvents (Class
3) should be used where practical.
[0020] Methylene chloride and methanol are classified as Class 2 solvents; such solvents should be limited in pharmaceutical products because of their inherent toxicity. The limit for residual solvent is 600 ppm for methylene chloride and 3000 ppm for methanol. Halogenated solvents are carcinogenic or are suspected to be carcinogenic and such solvent should be used under strict conditions during technological process, requiring special conditions to prevent exposure of workers to the solvent. These solvent are not allowed to be released into environment and should be insinuated e.g. by pyrolysis, such measures increase the production cost.
[0021] Thus in view of the prior art disclosures, there is a need for pharmaceutical compositions comprising Empagliflozin, which are physically and chemically stable, have improved dissolution profde and are prepared by an economical process suitable for use on a commercial scale. There is also a need to use a solvent which is safe to be used as industrial solvent, is safe to consumers, is environmentally friendly and does not require a special waste measures in contrast to solvents classified as Class 1 or 2.
[0022] It is an object of the invention to provide pharmaceutical compositions and dosage forms comprising Empagliflozin that have advantages compared to the conventional pharmaceutical compositions and dosage forms comprising Empagliflozin.
[0023] This object has been achieved by the subject-matter of the patent claims.
[0024] It has been surprisingly found that pharmaceutical dosage forms comprising Empagliflozin in the form of an amorphous solid solution with at least one polymer can be prepared by simple technological process using fluid bed granulation process and using a specific ratio between Empagliflozin and the at least one polymer. It has been found that pharmaceutical dosage forms comprising Empagliflozin in the form of solid amorphous solution with at least one polymer prepared by a fluid bed granulation process results in excellent physical and chemical stability.
[0025] As used herein, the term "stable" or "stability" means that the pharmaceutical dosage form is physically and chemically stable, whereas "chemically stable" means that the solid pharmaceutical dosage form when stored at 40 °C and 75 % relative humidity for 3 or 6 months, each of the degradation impurity is less than 0.2 % by weight of Empagliflozin and the total impurities, which is the sum of known and unknown impurities, is less than 2% by weight of Empagliflozin. The term "physically stable" as used herein means that X-ray powder diffraction pattern (XRPD) of the solid pharmaceutical dosage form according to the invention when stored at 40 °C and 75 % relative humidity for 1 month in a closed vial does not exhibit detectable X-ray diffractions characteristic of the crystalline form of Empagliflozin. [0026] The invention therefore provides a physically and chemically stable form of Empagliflozin, namely an amorphous solid solution with at least one polymer, which can be prepared by a simple technological process. The invention provides pharmaceutical dosage forms that allow for accomplishing advantageous stabilization effects while maintaining excellent dissolution characteristics of Empagliflozin and suitability for industrial scale production.
[0027] The invention generally relates to a solid pharmaceutical dosage form, comprising
(i) as the active ingredient, Empagliflozin, in the form of an amorphous solid solution, typically with at least one polymer,

[0180] Preferably, the granules obtained in step (c), optional step (d) and/or optional step (e) have an average particle size (CED - circular equivalent diameter) in the range of from 20 pm to 1000 pm, preferably from 50 pm to 600 pm, and most preferably from 80 pm to 350 pm. The particle size distribution is given in terms of volume and is determined by means of well-known image analysis algorithms.
[0181] Step (f) of the process according to the invention is optional. When the properties of the granules obtained in step (c) cannot be directly compressed to e.g. tablets but require further excipients, these further excipients are preferably provided as extragranular material in substep (i) of step (f) of the process according to the invention.

[0186] Typical compression forces are within the range of from 1 kN to 100 kN, preferably within the range of from 1 to 50kN.
[0187] Step (h) of the process according to the invention is optional. Suitable devices for coating compacts are known to the skilled person and are commercially available. Preferably, coating step (h) is performed using an aqueous solution of film forming excipients such as Opadry. In a special embodiment of the present invention compact or tablet cores obtained in step g) can be optionally coated with a coating dispersion containing a further active ingredient and at least one additional excipient selected from binders, diluents, antitacking agents dispersed in a solvent such as purified water or its mixtures with volatile organic solvents.

The particle size distribution is given in terms of volume and is determined by means of well-known image analysis algorithms.
[0193] Granule size can be of particular importance, since the content uniformity, dissolution behavior and thus the bioavailability depend on the granule size distribution.

[0197] The following examples illustrate the invention and are not intended to restrict the scope of the invention, as defined by the appended claims, in any way.
Methods:
[0198] Stability testing: The pharmaceutical compositions were stored in vials at 40 °C/75%RH for 1 month. Stability of amorphous phase was monitored by X-ray powder diffraction pattern. XPRD data was obtained in order to determine if a sample remains in the starting form, indicating that it is stable under these conditions or transformed partially or completely into a crystalline material, indicating that it is not stable under these conditions.
[0199] Powder X-ray diffraction patterns: Measurements were carried out using an X-ray diffractometer (PANalytical X’Pert PRO MPD, Almelo, NL) with Cu Ka radiation (l = 1.5418 A) at 45 kV and 40 mA and X' Celerator detector.
[0200] Particle size distributions of granules: Measurements were carried out using a Camsizer® XT device (Retsch Technology GmbH, Germany) equipped with the X-Jet plug-in cartridge and its related software. The Camsizer® set-up employs a dynamic imaging technique, rather than physical sieving of the particles. Samples are dispersed by pressurized air and passed through a gap illuminated by two pulsed light sources. The images of the dispersed particles (more specifically of their projections) are recorded by two digital cameras at a take-up rate of 60 images per second. The mean particle size as used herein is a weighted arithmetic mean value as measured by dynamic image analysis, such as according to ISO 13322-2. The particle size distribution is given in terms of volume and is determined by means of well-known Image analysis algorithms.
[0201] Raman spectra: Measurements were carried out using an alpha500 AR commercial confocal reflectance Raman microscope (WITec) with a 532 nm Nd:YAG laser source, 30 mW output. Imaging technique was performed in case of formulation analysis. Cross-sections with total imaging area of 600 pm c 600 pm were recorded, and relevant Raman spectrum characteristic for regions of amorphous solid solution was exported. Raman spectrum of amorphous solid solution obtained by evaporation and Raman spectrum of powder sample of crystalline API were also recorded (as shown in figure 2).
[0202] Differential scanning calorimetry (DSC): Measurements were carried out using DSC 1 Mettler Toledo scanning calorimeter. Samples of approx. 3 mg were scanned at a heating rate of 1 °C/min using temperature modulation with amplitude of +- 0,4 K and period of 30 s between -20 °C and 200 °C. Nitrogen atmosphere was used (40ml/min) and samples were scanned in aluminum pans, covered with pierced lid. [0203] Dissolution Profile: The dissolution testing illustrated in Figure 4 was carried out in 900 ml of dissolution medium (0.1 M hydrochloric acid). The dissolution testing was performed during 15 minutes at a rotation speed of 100 rpm. The dissolution testing was carried out at a temperature of the dissolution medium of 37°C±0.5°C (especially 37°C). The apparatus used for dissolution testing was USP apparatus I (Basket).
[0204] The dissolution testing illustrated in Figures 5 and 6 were carried out in 900 ml of dissolution medium (50 luM Phosphate buffer having pH 6.8). The dissolution testing was performed during 20 minutes at a rotation speed of 100 rpm. The dissolution testing was carried out at a temperature of the dissolution medium of 37°C±0.5°C (especially 37°C). The apparatus used for dissolution testing was USP apparatus I (Basket).
Reference Example 1 - Empagliflozin : PVP weight ratio 1:2 - amorphous solid solution
[0205] 500 mg of Empagliflozin and 1 g of Povidone K30 were suspended in 10 ml of ethanol. The mixture was heated to 72 °C until completely dissolved; the obtained solution was further stirred for lh at elevated temperature. The solution was then completely evaporated in a rotary vacuum evaporator at temperature of 40 to 60 °C and pressure of less than 50 mbar. The product was further dried in a vacuum drier at temperature of 40 °C and a pressure of 40 mbar.
