PHARMACEUTICAL COMPOSITIONS

BACKGROUND

The chemical name of nilotinib free base is 4-methyl-N-[3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)phenyl]-3-{[4-(pyridin-3-yl)pyrimidin-2-yl]amino}benzamide. Nilotinib hydrochloride is approved for the treatment of chronic myelogenous leukemia (CML) under the trade name TASIGNA. The structure of nilotinib free base is depicted below.

Nilotinib is a lipophilic compound, with a cLog P=5.8, making the compound practically insoluble in water. TASIGNA is known to have the potential to result in increased and highly variable exposures when administered with meals. Significant prolongation of the QT interval may occur when nilotinib is inappropriately taken with food and/or strong CYP3A4 inhibitors and/or medicinal products with a known potential to prolong QT. Therefore, coadministration with food must be avoided and concomitant use with strong CYP3A4 inhibitors and/or medicinal products with a known potential to prolong QT should be avoided. Sudden deaths have been reported in 0.3% of patients with CML treated with TASIGNA in clinical studies of 5,661 patients. The relative early occurrence of some of these deaths related to the initiation of TASIGNA suggests the possibility that ventricular repolarization abnormalities may have contributed to their occurrence.

There is a need for nilotinib compositions that have improved oral bioavailability, permit administering lower doses, that reduce absorption variations caused by food intake, and that reduce in vivo inter-subject absorption variations. More generally, there is a need for improved formulations of highly lipophilic active pharmaceutical ingredients to provide improved oral bioavailability, permit administering lower doses, that reduce absorption variations caused by food intake, and that reduce in vivo inter-subject absorption variations.

Amorphous Solid Dispersion

The present disclosure relates to pharmaceutical compositions and methods of administering thereof, the pharmaceutical compositions comprising an amorphous solid dispersion comprising a lipophilic API, hydrophilic polymer, and a surfactant. In some embodiments, the amorphous solid dispersions described herein additionally comprise one or more adsorbents. In some embodiments, the amorphous solid dispersions described herein additionally comprise one or more other additives. In some embodiments, other additives comprise organic and inorganic acids. In some embodiments, a solid dispersion is a solid state solution wherein an API (or API salt) and hydrophilic polymer act as solute and solvent, respectively. The solid dispersion can form multiple structures depending on the composition and sample processing history. When the API loading is lower than the equilibrium solubility of API in the hydrophilic polymer, the drug is molecularly dispersed within the polymer matrix and forms a thermodynamically stable, homogeneous solution. A homogenous solution is often attainable only at very low API loading and/or high temperature. For higher loadings, the mixture becomes a supersaturated solution and the drug precipitates out. This can result in a dispersion of crystalline API particles in a hydrophilic polymer matrix, in which the drug concentration corresponds to its equilibrium solubility at that temperature. Alternatively, as API crystallization can be a slow process, an intermediate meta-stable structure may form in which amorphous API aggregates are dispersed in a hydrophilic polymer matrix containing the API in a non-crystalline amorphous state. Such amorphous solid dispersions can provide superior dissolution properties, as compared to the crystalline API.

Amorphous solid dispersions described herein may comprise an API, hydrophilic polymer, and a surfactant. In some embodiments, the amorphous solid dispersions described herein additionally comprise one or more adsorbents. In some embodiments, the amorphous solid dispersions described herein additionally comprise one or more other additives. In some embodiments, other additives comprise organic and inorganic acids. In some embodiments, other additives comprise antioxidants. In some embodiments, the amorphous solid dispersions described here are homogenous amorphous solid dispersions.

Active Pharmaceutical Ingredient (API)

Various embodiments described herein are directed to compositions comprising an effective amount of an active pharmaceutical agent (API). “Active pharmaceutical agent,” “API,” “drug,” “pharmaceutically active agent,” “bioactive agent,” “therapeutic agent,” and “active agent” and the like may be used interchangeably and refer to a substance, such as a chemical compound or complex, that has a measurable beneficial physiological effect on the body, such as a therapeutic effect in treatment of a disease or disorder, when administered in an effective amount. Further, when these terms are used, or when a particular active agent is specifically identified by name or category, it is understood that such recitation is intended to include the active agent per se, as well as pharmaceutically acceptable, pharmacologically active derivatives thereof, or compounds significantly related thereto, including without limitation, salts, pharmaceutically acceptable salts, N-oxides, prodrugs, active metabolites, isomers, fragments, analogs, solvates hydrates, radioisotopes, etc.

The partition-coefficient (P) as referenced herein is a ratio of concentrations of a compound between two immiscible solvent phases at equilibrium. Most commonly, one of the solvents is water and the other is hydrophobic, typically 1-octanol. The logarithm of the ratio is log P, as shown below, (conventionally the lipophilic phase is the numerator and hydrophilic phase is the denominator.)

$\log P_{o c t a n o l / w a t e r} = \log (\frac{{[solute]}_{octanol}}{{[solute]}_{water}})$

log P is a measure of lipophilicity or hydrophobicity. Hydrophobicity affects drug absorption, bioavailability, hydrophobic drug-receptor interactions, metabolism of molecules, and toxicity. Hydrophilic compounds are soluble in water (“water-loving”) and polar solvents. Lipophilic compounds are less soluble in water (“water-fearing” or hydrophobic) and polar solvents, but are more soluble in organic solvents. Thus:

Low hydrophilicity=high lipophilicity=high log P=poor aqueous solubility=poor absorption.

High hydrophilicity=low lipophilicity=low log P=good aqueous solubility=good absorption.

Partition coefficients can be measured experimentally or estimated via calculation. Various methods for calculating (or predicting) log P have been developed, typically by fitting calculated log P values with experimentally measured log P values for training sets of thousands of molecules, mostly drug-like. Log P calculations are considered very robust and accurately process many organic molecules. For example, over 50% of molecules log P is predicted with error of less than 0.25, while over 80% with error of less than 0.5. Less than 3.5% of structures are predicted with an error greater 1.0. To distinguish from a measured log P, a calculated log P is sometimes written as clog P. Unless otherwise indicated, “log P” as used herein refers to an experimental log P value.

In some embodiments, the API is lipophilic. An API is considered lipophilic if its log P or calculated log P is 2.0 or higher. A log P of 2.0 or higher denotes that the solubility of the API is 100-fold or higher in a lipophilic solvent than in water. In some embodiments, the API is insoluble in polar solvents. In some embodiments, the API is insoluble in aqueous media. In some embodiments, the API is insoluble in water.

In some embodiments, the lipophilic API has a log P of at least 2.0, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, or 7.0.

An acid dissociation constant, Ka, (or acidity constant) is a measure of the strength of an acid or base in solution, typically water. It is the equilibrium constant for the chemical dissociation of acids and bases. In aqueous solution, the equilibrium of acid dissociation is written:

HA+H₂O custom-character A⁻+H₃O⁺

where HA is an acid that dissociates into A⁻, (the conjugate base of the acid) and a hydrogen ion (which combines with a water molecule to make a hydronium ion, H₃O⁺). The dissociation constant can also be written with the H₂O removed:

$HA ⇋ A^{-} + H^{+}$

$K_{a} = \frac{[A^{-}] [H^{+}]}{[H A]}$

The equilibrium of the dissociation of the conjugate acid of a base is written:

BH⁺+H₂O custom-character B+H₃O⁺

where BH⁺ (the conjugate acid of the base) dissociates into B (the free base), and a hydrogen ion, which combines with a water molecule to form a hydronium ion, H₃O⁺. The dissociation constant can also be written with the H₂O removed:

$B H^{+} ⇋ B + H^{+}$

$K_{b} = \frac{[B] [H^{+}]}{[B H^{+}]}$

pK_a, the logarithmic value of K_a, is more often used to express acid the strength/weakness of acids or the conjugate acid of bases:

pK_a=−log ₁₀(K_a)

The more positive the value of pK_a, the smaller the extent of dissociation, and the weaker the acid. In general, for acids:

pK_a=−2 to 12→weak acid(little or only partial dissociation in water)

pKa<−2→strong acid(completely or mostly dissociated in water)

while for bases:

pK_a<12→weak base(little or only partial dissociation in water)

pKa≥12→strong base(completely or mostly dissociated in water)

Methods of Manufacture

Disclosed herein is a method for preparing an amorphous solid dispersion, comprising the steps of (a) combining (i) an active pharmaceutical ingredient or a pharmaceutically acceptable salt thereof, (ii) one or more surfactants (e.g., polymeric non-ionic surfactants and phospholipids), (iii) a hydrophilic polymer (e.g., non-ionic hydrophilic polymer), (iv) optionally an adsorbent or adsorbents, (v) optionally other additional additives and (vi) a solvent or solvent mixture, thereby producing a liquid mixture (a solution or suspension), and (b) removing all or a part of the solvent from said mixture, thereby producing an amorphous solid dispersion. In some embodiments, the solvent is selected from an organic solvent and water. In some embodiments, the organic solvent is ethyl acetate, ethanol, isopropanol, or methanol, n-butanol, n-propanol, isopropanol, formic acid, nitromethane, ethanol, acetic acid, N-methylpyrrolidone, tetrahydrofuran (THF), methyl acetate, dimethylformamide, acetonitrile, dimethyl sulfoxide, dichloromethane (DCM), acetone, and any combination thereof. In some embodiments, the solvent is an alcohol. In some embodiments, the alcohol is ethanol. In some embodiments, the solvent is selected from dichloromethane, methanol, tetrahydrofuran, and acetone. In some embodiments, the solvent is selected from a mixture of these solvents. In some embodiments, combining comprises dissolving the active pharmaceutical ingredient or a pharmaceutically acceptable salt thereof, the surfactant, the non-ionic hydrophilic polymer, and optionally an adsorbent and/or additional additives in the solvent. In some embodiments, the adsorbent is suspended in the solvent. In some embodiments, removing of the solvent comprises spray-drying or rotor evaporation. In some embodiments, the API is an API of Table 1 or a pharmaceutically acceptable salt thereof.

In some embodiments, the method for preparing an amorphous solid dispersion, comprises the steps of (a) combining (i) an active pharmaceutical ingredient or a pharmaceutically acceptable salt thereof, (ii) one or more surfactants (e.g., polymeric non-ionic surfactants and phospholipids), (iii) a hydrophilic polymer (e.g., non-ionic hydrophilic polymer), (iv) optionally other additional additives and (v) a solvent or solvent mixture, to produce a liquid mixture or solution; (b) spraying the liquid mixture or solution onto an adsorbent or adsorbents; and (c) removing all or a part of the solvent from the liquid mixture or solution to produce an amorphous solid dispersion. In some embodiments, the solvent is selected from an organic solvent and water. In some embodiments, the organic solvent is ethyl acetate, ethanol, isopropanol, or methanol, n-butanol, n-propanol, isopropanol, formic acid, nitromethane, ethanol, acetic acid, N-methylpyrrolidone, tetrahydrofuran, methyl acetate, dimethylformamide, acetonitrile, dimethyl sulfoxide, dichloromethane (DCM), acetone, and any combination thereof. In some embodiments, the solvent is an alcohol. In some embodiments, the alcohol is ethanol. In some embodiments, the solvent is selected from dichloromethane, tetrahydrofuran, methanol and acetone. In some embodiments, the solvent is selected from a mixture of these solvents. In some embodiments, combining comprises dissolving the active pharmaceutical ingredient or a pharmaceutically acceptable salt thereof, the surfactant, the non-ionic hydrophilic polymer, and optionally additional additives in the solvent. In some embodiments, an amorphous solid dispersion is produced by a fluid-bed spraying and drying process. In some embodiments, an amorphous solid dispersion is produced by rotor evaporation.

In an exemplary manufacturing workflow, an amorphous solid dispersion is formed by first the API, hydrophilic polymer, surfactant, and optionally an additive or additives in a solvent or water at a room temperature or heated to form a clear solution. The clear solution is then spray dried to form an amorphous solid dispersion. Additionally, an amorphous solid dispersion is formed by first the API, hydrophilic polymer, surfactant, and optionally an additive or additives in a solvent or water in a room temperature or heated to form a clear solution. An adsorbent or a mixture of adsorbents is further added at a room temperature or heated to form a homogenous suspension. The homogenous suspension is then spray dried to form an amorphous solid dispersion. Following the formation of an amorphous solid dispersion, the amorphous solid dispersion is mixed with other additives and excipients used in the formulation. The mixture is then pressed into tablets or loaded into capsules.

A typical spray dryer comprises three chambers, a drying chamber, a cyclone chamber and a sample collection chamber. During the spray drying process, the spray dried dispersion solid is collected in the sample collection chamber. However, the solid may also reside on the surfaces of the drying chamber and cyclone chamber, thus causing a low production yield (a low amount of solid in the sample collection chamber). In some embodiments, the amorphous solid dispersions comprising of an API, a hydrophilic polymer and a surfactant have low production yields. When an adsorbent is incorporated into these amorphous solid dispersions, the production yield can be significantly increased. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 10%, in comparison to the solid dispersion without an adsorbent. For clarity, the term of percentage means to be the absolute difference of the yields. For example, if the production yield of an amorphous solid dispersion without an adsorbent is 10% and the production yield of an amorphous solid dispersion with an adsorbent is 20%, the increase of the yield is the difference of these two yields, i.e., 10%. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 20%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 30%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 40%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 50%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 60%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 70%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 80%, in comparison to the solid dispersion without an adsorbent. In some embodiments, the production yield of an amorphous solid dispersion with an adsorbent is increased by at least 90%, in comparison to the solid dispersion without an adsorbent.

General Preparation for the Amorphous Solid Dispersion by Spray Drying

The active pharmaceutical ingredient, polymer, and optionally any surfactants and/or additives were dissolved in a solvent or solvent mixture at a room temperature and up to 80° C. to form a clear solution. The total amount of solids added into the solution is about 5% to 15%. In some cases when an adsorbent was added, a homogenies suspension was formed. A bench top spray dryer was preheated until a steady state was achieved. The solution was then introduced into the spray dryer via flash atomization at a feed rate of about 3-5 rpm, at an inlet drying gas temperature of about 50-150° C., and an outlet temperature of about 40-45° C., and a pressure of about 2-3 bar. After collection, the particles were placed into a convection tray dryer operated at 30° C. or above.

Specifically, the processing parameters of the spray drying process for the formulations in the tables from Table 3-Table 8 are listed in Table 16 and Table 17.

For Formulation 8b, the surface modified tartaric acid was prepared by spraying of a 300 g of 10% sodium carbonate aqueous solution (30 g of Na₂CO₃in 270 g of the aqueous solution) onto 500 g of tartaric acid in a powder bed and then dried in a fluid bed equipment. About 6% weight of sodium carbonate based on tartaric acid was sprayed onto the tartaric acid surface. The sodium carbonate solution reacts with the tartaric acid powder to form a neutral salt layer and generate the surface modified acid. The surface modified acid differs from an unmodified acid, in that there is a protective neutral layer that at least partially insulates the acid and reduces interaction with other compounds in the formulation, such as the active ingredient.

Formulation 10 was prepared by mixing the ASD for Formulation 10 (shown in Table 8) with additional excipients and then compressed into tablets, based on Table 24.

Similar to Formulation 12b, Formulation 13 and Formulation 14 shown in Table 26 and Table 27, the 2% surface modified tartaric acid used in Formulations 20a, 20b, 21, 22, and 23 shown in Tables 31 and 32 was prepared by spraying about 2% weight of sodium carbonate onto the tartaric acid surface.

While particular embodiments described herein have been shown and described herein, such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments described herein may be employed in practicing the invention. It is intended that the following claims define the scope and that methods and structures within the scope of these claims and their equivalents be covered thereby.

Example 4: Oral Bioavailability of ASD Formulations in Dogs

The in vivo pharmacokinetic properties (T_max, C_max, AUC) of nilotinib compositions were examined by administering such compositions to beagle dogs, as described below.

Comparison of Bioavailability of ASD Formulations with that of TASIGNA in Dogs

Beagle dogs, (3 male and 3 female), were fasted for 12 hours before administration. Test formulations were orally administered to each dog with 50 mL of water at the time of the administration. Blood samples were collected at 0.25, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 24 hours after administration and the concentrations of nilotinib in plasma were determined. From these measurements, C_max, T_maxand AUC were calculated and are presented in Table 33 to Table 35 below.

Table 33 compares pharmaceutical formulations with various physical states. Formulation 1 is an amorphous solid dispersion (ASD) formulation without surfactant and with an acid. Although the nilotinib HCl is present in a 55 mg dose (equivalent to 50 mg of nilotinib, a ratio of 1.1 between nilotinib HCl and nilotinib), the bioavailability is comparable to a 220 mg dose (equivalent to 200 mg of nilotinib, a ratio of 1.1 between nilotinib HCl and nilotinib) in the listed drug product TASIGNA. The dog study was performed by a cross-over design for the formulations listed in Table 33. The drug product TASIGNA is marketed in three dosage forms of nilotinib hydrochloride at equivalent doses of 50 mg, 150 mg, and 200 mg of nilotinib free base. The dosage forms are formulated as hard capsules and include the following excipients: lactose monohydrate, crospovidone, poloxamer, colloidal silica, anhydrous/colloidal silicon dioxide, and magnesium stearate. The nilotinib hydrochloride in the TASIGNA formulation is not known to be incorporated into an amorphous solid dispersion. The API in the TASIGNA formulation is in its crystalline state, while the API in Formulation 1 is part of amorphous solid dispersion (ASD).

Table 33 shows the benefits of using an amorphous solid dispersion to carry the API. The C_maxand AUC_∞ for Formulation 1 is similar to that of TASIGNA, despite TASIGNA having four times the amount of API.

Table 34 compares formulations with amorphous solid dispersions comprising mg of nilotinib HCl (equivalent to 50 mg of nilotinib free base) and various polymers, surfactants, and acids (Formulations 2a and 2b) with a 220 mg dose (equivalent to 200 mg nilotinib) in the listed drug product TASIGNA. The dog study was performed in a cross-over design. Table 34 highlights the unexpected advantage of incorporating lecithin or Polaxamer 188 into an amorphous solid dispersion with nilotinib HCl and polymer. Despite using only one quarter of nilotinib HCl, the bioavailability of the API is twice that of the commercialized drug product. Reducing API loading while maintaining bioavailability can lead to a reduction in unwanted side effects.

Table 35 compares acid free amorphous solid dispersions comprising 55 mg of nilotinib HCl (equivalent to 50 mg of nilotinib) and various polymers, surfactants, and acids (Formulations 3a and 3b) with a 220 mg dose (equivalent to 200 mg of nilotinib) in the listed drug product TASIGNA.

In a cross-over design dog study, Formulations 3a and 3b are particularly noteworthy for two reasons. First, the doses of Formulations 3a and 3b are roughly one quarter the dose of the listed drug product TASIGNA, yet the bioavailability results are comparable. Second, no unmodified organic acid is used in the Formulation 3a or 3b, thus precluding the formation of a toxic impurity that forms during storage (see Example 5 below). In addition, the C_maxand AUC results for Formulation 3a are observed to be slightly superior to the results for Formulation 3b.

Comparison of Bioavailability of ASD Formulations in Fed and Fasted Dogs

Beagle dogs, (3 male and 3 female), were randomly divided into three groups. The three-period cross-over experiment design was adopted. The dogs were fasted for 12 hours before the experiment. Group 1 was administered with Formulation 3a in the fasted condition. Group 2 was administered with Formulation 3a in the fed condition. For the fed condition, dogs were fed with dog food (Shoobree, China) mixed with butter (Anchor, New Zealand) in a ratio of 100 g:16.4 g with 500 calories. Group 3 was administered TASIGNA under the fasted conditions. Test formulations were orally administered to each dog with 50 mL of water at the time of the administration. Blood samples were collected at 0.25, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 24 hours after administration and the concentrations of nilotinib in plasma were determined. From these measurements, the parameters of C_max, T_maxand AUC were calculated and are presented in Table 36 below.

One limitation of the commercialized drug product TASIGNA is the requirement to be administered under fasted conditions. Groups 1 and 2 show a similar C_maxand AUC in both the fed and fasted states. Formulation 3a shows an improvement over the current technology by eliminating the requirement of administration in the fasted state only. The bioavailability is higher that the commercialized product administered to Group 3, despite the dose of Formulation 3a being one quarter of the commercialized drug product.

Formulation 4 is shown to be effective in both fed and fasted states in Table 37 above. This constitutes an improvement over the current technology by eliminating the requirement of administration in the fasted state only. Groups 1 and 2 show a similar Cmax and AUC in both the fed and fasted states. The bioavailability is higher that the commercialized product administered to Group 3, despite the lower dose of Formulation 4. Oral absorptions of tablet formulations of ASD in dogs were also evaluated with a similar study design as described for Table 36 and Table 37, with the only difference being a different food was used for the fed condition. For these studies, the dogs were fed by oral gavage of food composed of 25 grams of dog food, 150 mL of full fat milk and 60 grams of bacon.

Table 38 shows the in vivo exposures in dogs of TASIGNA tablets under three different administration conditions. In this experiment, the dogs administered under the fasted condition are also given 6 μg/kg IM injection of pentagastrin. The exposure has three-fold increase in Cmax and four-fold increase in AUC when the product is administered after a high fat food. In addition, co-administration with an anti-acid medication (50 mg of Ranitidine per dog by IM injection) will significantly decrease the exposure.

Table 39 and Table 40 show the in vivo exposures in dogs of tablet formulations of Formulation 11a and Formulation 11b (see Table 25 for composition). Formulations 11a and 11b differ in that 11b additionally includes 100 mg of tartaric acid in the external granule materials. The results in Table 39 and Table 40 show two results. Firstly, the results suggest that the food effect has been significantly decreased and the dose could be reduced by four-fold, i.e., the in vivo exposure of the 50 mg dose of Formulation 11a and Formulation 11b is almost equivalent to 200 mg dose of TASIGNA. Secondly, the results show that the inclusion of an additional acid in the external granulation materials increases C_maxand AUC.

Table 41 to Table 43 show the in vivo exposures in dogs of tablet formulations of Formulation 12 to Formulation 14 administered with and without food. The food effect is somewhat increasing as the ratio of API and surfactant components increases, but is still significantly lower than the food effect of TASIGNA, indicating the amorphous solid dispersion formulation decreases food effect across a range of dosages.

Oral absorptions of tablet formulations of ASD in dogs were also evaluated with the similar study design as described for Table 36 and Table 37, with the only difference is that a different food was used for the fed condition. For these studies, the dogs were fed by oral gavage of the food composed of 25 grams of dog food, 150 mL of full fat milk and 60 grams of bacon.

Comparison of Bioavailability of an ASD Formulation in Fasted Dogs with Modulated Stomach pH

Beagle dogs, (3 male and 3 female), were randomly divided into three groups. The three-period cross-over experiment design was adopted. The dogs were fasted for 12 hours before the experiment. All three groups were administered with Formulation 3a in the fasted condition. The test formulation was orally administered to each dog with 50 mL of water at the time of the administration. Group 1 was injected with 6 μg/kg pentapeptide gastrin into each dog's muscles 45 mins prior to oral administration. Group 2 was intravenously injected with 50 mg ranitidine 1 hour before oral administration. Group 3 was the control group. Blood samples were collected at 0.25, 0.5, 1, 1.5, 2, 3, 4, 8, 12, 24 hours after administration and the concentrations of nilotinib in plasma were determined. From these measurements, the pharmacokinetic parameters of C_max, T_maxand AUC were calculated and are presented in Table 44 below.

The study measures the efficacy of Formulation 3a in dogs with high and low stomach pH. Pentapeptide gastrin could stimulate the acid release in stomach and ranitidine could inhibit acid release in stomach. The model simulates the stomach of patients under the effect of acid reducing drugs. The commercialized product TASIGNA is known to have reduced in-vivo absorption for patients taking anti-acid medication such as proton pump inhibitors (PPI).

As seen in Table 44, the pharmacokinetic parameters of C_maxand AUC between Groups 1 and 2 are only about 30% difference and the parameters have minimal difference between Groups 2 and 3, while TASIGNA has a significant reduction of in vivo exposure after co-administration of an anti-acid medication (50 mg of Ranitidine per dog by IM injection), as shown in Table 38. These data suggest that the formulations described herein may be administered to patients taking anti-acid medication.

Example 5: Formation of Genotoxic Impurities in Amorphous Solid Dispersions of Nilotinib and Acid

Formulations 2a and 2b in Example 4 show that amorphous solid dispersions of nilotinib and acidic excipient can result in vastly superior bioavailability (see Table 39 and Table 40). However, nilotinib HCl often yields a genotoxic impurity in the amorphous solid dispersion with acidic excipients. Under acidic conditions, nilotinib hydrolyzes to form 3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)aniline (herein after termed “impurity A”) as show below.

A degradation study was performed with amorphous solid dispersion formulations, Formulation A, Formulation B, and Formulation C, to compare the stability of different compositions. Formulation A was formulated as an amorphous solid dispersion of 55 mg nilotinib HCl, 100 mg citric acid, 100 mg lecithin, and 100 mg PVP K30. Formulation B was formulated as an amorphous solid dispersion of 55 mg nilotinib HCl, 100 mg lecithin, and 100 mg PVP K30. Formulation C was formulated as an amorphous solid dispersion of 55 mg nilotinib HCl, 75 mg citric acid, and 100 mg PVP K30. The Formulation powders were placed at 40° C./RH 75%, and 75° C./RH 75% condition for two weeks. Formulation C was formulated as an amorphous solid dispersion of 55 mg nilotinib HCl, 75 mg citric acid, and 100 mg PVP K30. The Formulation powders were placed at 40° C./RH 75%, and 75° C./RH 75% condition for two weeks. Genotoxicity impurity A was measured by a HPLC-MS method and the results are shown below in Table 45. The concentrations of genotoxic impurity A were found high for Formulation A and C, but low for Formulation B. The parameters of the degradation study were according to European Pharmacopeia 9.8; July, 2019:2993, which provides detailed parameters for evaluating the purity of a sample of nilotinib hydrochloride monohydrate.

In addition, tablets of Formulation 12a and Formulation 12c were packaged in HDPE bottles with 2 grams of desiccant and then stored at 40° C./75% RH for up to six months. The ASD powder of Formulation 12 (shown in Table 9) was packaged and sealed in an aluminum pouch and then also stored at the same storage condition (40° C./75% RH)

The level of Impurity A was measured by a HPLC-MS method and the results are shown below in Table 46. Note that the ASD of Formulation 12 has no acid component and has the lowest level of impurity A. Formulation 12c, which has the ASD of Formulation 12 and 6% surface-modified tartaric acid, has a similar level of impurity A. However, Formulation 12a, which has the component of ASD of Formulation 12 and tartaric acid without surface modification, has a significantly increased level of impurity A. This results suggest that the surface modification can reduce the formation of impurity and improve the stability of API during storage.

Example 6: In Vivo Exposure of ASD Tablet Formulation in Humans

A tablet formulation (Formulation 11a) was tested for its in vivo exposure in humans. This study was performed by a three-way cross-over design and with 18 healthy volunteers. Formulation 11a was administered under the overnight fasting condition and after consumption of a high-fat, high-calorie food (approximately 800 to 1000 calories with 150, 250, and 500 to 600 calories from protein, carbohydrate and fat, respectively) within 30 minutes. In addition, TASIGNA tablet formulation administered under the overnight fasting condition was also tested for comparison. Blood samples were collected at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 hours after administration and the concentrations of nilotinib in plasma were determined by a HPLC method. From these measurements, the parameters of C_max, T_maxand AUC were calculated Winnonlin 8.3.1 and are presented Table 47 below.

The results suggest that the amorphous solid dispersion technology applied in this tablet formulation has significantly reduced the food effect, in comparison to the results in Table 39. The in vivo exposure of the formulation at 50 mg strength is slightly lower than that of TASIGNA (at 200 mg strength. However, given the results from the animal studies, Formulation 11a is expected to be higher that TASIGNA if compared at the same dose strength (200 mg). In vivo exposure in humans is also expected to increase upon the addition of acid in the external granule materials.

A tablet formulation with acid in the external granule materials (such as, for example Formulations 11b, 12a, 12b, 12c, 13, 14, 20a, 20b, 21, 22, and 23) will be tested for in vivo exposure in dogs and humans. This study will be performed by a three-way cross-over design and with healthy volunteers. The formulation will be administered under the overnight fasting condition and after consumption of a high-fat, high-calorie food (approximately 800 to 1000 calories with 150, 250, and 500 to 600 calories from protein, carbohydrate and fat, respectively) within 30 minutes. In addition, TASIGNA tablet formulation will be administered under the overnight fasting condition for comparison. Blood samples will be collected at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 hours after administration and the concentrations of nilotinib in plasma will be determined by a HPLC method. From these measurements, the parameters of C_max, T_maxand AUC will be calculated Winnonlin 8.3.1.
