Description

WO 2011/002857 PCT/US2010/040555 -1 3-CYANOQUINOLINE TABLET FORMULATIONS AND USES THEREOF FIELD OF THE INVENTION The present invention relates to formulations of certain cyanoquinoline compounds. In particular, the invention is directed to stable tablets of a 3 cyanoquinoline compound, 4-(2,4-dichloro-5-methoxy-phenylamino)-6-methoxy-7-[3-(4 5 methyl-piperazin-1-yl)-propoxy]-quinoline-3-carbonitrile, and further comprising the super-disintegrant croscarmellose sodium, a surfactant polyethylene oxide sorbitan monooleate (polysorbate/Polyoxyethylene sorbitan monooleate (Tween-80

TM

), or both BACKGROUND OF THE INVENTION Certain 3-cyanoquinoline compounds and pharmaceutically-acceptable salts thereof, are protein kinase inhibitors and possess anti-tumor activity and are 10 therefore useful for treating certain disease states, such as cancer, that result, at least in part, from deregulation of this receptor. Receptor tyrosine kinases are important in the transmission of biochemical signals, which initiate cell replication. They are large enzymes which span the cell membrane and possess an extracellular binding domain for growth factors such as epidermal growth factor receptor (EGFR) and an intracellular 15 portion which functions as a kinase to phosphorylate tyrosine amino acids in proteins and hence to influence cell proliferation. Various classes of receptor tyrosine kinases are known (Wilks, Advances in Cancer Research, 1993, 60, 43-73) based on families of growth factors, which bind to different receptor tyrosine kinases. The classification includes Class I receptor tyrosine kinases comprising the EGFR family of receptor 20 tyrosine kinases such as the EGFR, TGFa, Neu and erbB receptors, Class || receptor tyrosine kinases comprising the insulin family of receptor tyrosine kinases such as the insulin and IGFI receptors and insulin-related receptor (IRR) and Class Ill receptor tyrosine kinases comprising the platelet-derived growth factor (PDGF) family of receptor tyrosine kinases such as the PDGFa, PDGFO and colony-stimulating factor 1 (CSF1) 25 receptors. It is also known that certain tyrosine kinases belong to a class of non receptor tyrosine kinases which are located intracellularly and are involved in the transmission of biochemical signals such as those that influence tumor cell motility, 30 dissemination and invasiveness and subsequently metastatic tumor growth (Ulkich et WO 2011/002857 PCT/US2010/040555 -2 al., Cell, 1990, 61, 203-212, Bolen et al., FASEB J., 1992, 6, 3403-3409, Brickell et al., Critical Reviews in Oncogenesis, 1992, 3, 401-406, Bohlen et al., Oncogene, 1993, 8 2025-2031, Courtneidge et al., Semin. Cancer Biol., 1994, 5, 239-246, Lauffenburger et al., Cell, 1996, 84, 359-369, Hanks et al., BioEssays, 1996, 19, 137-145, Parsons et al., 5 Current Opinion in Cell Biology, 1997, 9, 187-192, Brown et al., Biochimica et Biophysica Acta, 1996, 1287, 121-149 and Schlaepfer et al., Progress in Biophysics and Molecular Biology, 1999, 71, 435-478). Various classes of non-receptor tyrosine kinases are known including the Src-family such as the Src, Lyn and Yes tyrosine kinases, the Ab family such as Ab and Arg and the Jak family such as Jak 1 and Tyk 2. 10 The 3-cyanoquinoline compound 4-(2,4-dichloro-5-methoxy-phenylamino) 6-methoxy-7-[3-(4-methyl-piperazin-1-yl)-propoxy]-quinoline-3-carbonitrile, also referred to as SKI-606, or bosutinib, is a weak base with an intrinsic solubility of approximately 0.06 pg/mL at pH 8.0. Below pH 8, the solubility of the compound SKI-606 increases 15 exponentially with decreasing pH due to ionization. However, degradation of SKI-606 was observed at low pH aqueous solution (pH 3 and below) through hydrolysis, although the compound is relatively stable at pH higher than 5. Some problems with existing solid formulations of 3-cyanoquinolines 20 include variable dissolution, which appears to depend on the active pharmaceutical ingredient's (API) particle size. Contrary to the norm, the smaller API (Dgo-20 microns) in the Pill formulation appeared to retard dissolution, under similar processing conditions used for the larger API (Dgo-40 microns), as a result failing dissolution specification. This was observed more so with larger tablets (higher strength). 25 In addition, accelerated dissolution characteristic of formulations after aging/storage was also observed at early timepoints (small yet significant shifts on in dissolution on aging at both room temperature and under accelerated conditions). Results are presented in two dissolution methods: the 0.1 N HCI method and the 30 CTAB/pH 5 acetate method, further discussed below The latter method was selected to better show a dissolution profile at timepoints up to 30 minutes, as the 0.1 N HCI method was found to release all drug within the first 10-20 minutes.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 summarizes tablet dissolution rates for SKI-606 formulations comparing 10 different disintegrating agents (croscarmellose sodium versus crospovidone). Figure 2 summarizes dissolution on accelerated stability for a SKI-606 formulation including crospovidone. There appears to be a significant shift in tablet dissolution especially at early timepoints. 15 Figure 3 summarizes dissolution on accelerated stability for a SKI-606 formulation including croscarmellose sodium. No shift (compared to Figure 2) is observed in this case. 20 Figure 4 summarizes effects of varying Intra and Extragranular (IG and EG) Croscarmellose sodium concentrations in a SKI-606 formulation on tablet dissolution rates. Figure 5 summarizes effects of varying Intra and Extragranular (IG and EG) 25 Crospovidone concentration in a SKI-606 formulation on tablet dissolution rates. A wider dissolution is observed here showing strong concentration dependency of dissolution on ratios of Crospovidone. The formulation containing API of D90 appears to be markedly different in dissolution from the rest containing API of D90= 40 or 60 microns. 30 Figure 6 summarizes effects of active pharmaceutical ingredient (API) particle size on Dissolution for Crospovidone containing SKI-606 Formulation containing 2% binder, and 2% intragranular and extragranular disintegrant.

WO 2011/002857 PCT/US2010/040555 -11 Figure 7A and B summarizes the lack of effect of API particle size in both CTAB/acetate and 0.1 N HCI medias for the croscarmellose sodium based SKI-606 formulations. The CTAB/acetate media was considered a more discriminating media than the 0.1 N HCI. Compare this to Figure 9A and B that clearly show the disparate 5 effect of API particle size on tablet dissolution in a Crospovidone based tablet formulation. Figure 8 summarizes the lack of dissolution dependency of croscarmellose based SKI-606 formulations (Runs A, B and C) on tablet hardness within a range of 10 120-190 N thus attesting to the dissolution robustness of the formulation. Hardness of a tablet may routinely need to be modified in a manufacturing setting and this formulation clearly offers that ability to do so. Figure 9A and B summarizes effect of API particle size on tablet (100 and 500 15 mg strengths) dissolution for Crospovidone based formulations in 0.1 N HCI. Compare and contrast this to Figure 7A and B that do not show this dependency. Figure 10 summarizes upward shift in tablet dissolution a 500 mg Crospovidone based SKI-606 formulation on open dish accelerated stability upto 2 weeks. Dissolution 20 data is shown for 2 formulations with varying binder percentages and disintegrant ratios. Significant dissolution differences are observed early on during tablet dissolution for both batches, indicating a lack of dissolution reproducibility on accelerated stability. Compare and contrast this to croscarmellose sodium based formulation in Figure 11 that does not show any differences on stability 25 Figure 11 summarizes the lack of any dissolution shift of croscarmellose sodium (CCS) based formulation on stability under similar conditions as the Crospovidone (CPV) batches in Figure 10 30 Figure 12 Shows additional dissolution shift data for Crospovidone (CPV) SKI 606 formulation in 0.1 N HCI under accelerated aging conditions for 500 and 100 mg strength tablets. A consistent upward trend is observed for both the strengths in 0.1 N

HCL.

WO 2011/002857 PCT/US2010/040555 -12 Figure 13 summarizes comparative dissolution profiles for SKI-606 formulations with varying concentrations of a wetting agent (poloxamer). It is observed that poloxamer has the unexpected effect of decreasing tablet dissolution in a concentration dependent manner. 5 Figure 14 summarizes effects of wetting agent on granule dissolution in SKI-606 formulations. This effect shows that increases in poloxamer concentration resulted in increase in granule dissolution. 10 Figure 15 summarizes effects of accelerated aging uto 6 weeks open dish conditions at both 40 deg C and 40 deg C/75% RH for the SKI-606 formulations containing Polyoxyethylene sorbitan monooleate (Tween-80) as a wetting agent (API D9o = 38 microns).It is observed that there appears to be negligible shift even under the rigorous stability conditions in an open dish. 15 Figure 16 summarizes effects of accelerated aging uto 6 weeks open dish conditions at both 40 deg C and 40 deg C/75% RH for the SKI-606 formulations containing Polyoxyethylene sorbitan monooleate (Tween-80) as a wetting agent (API D9o = 18 microns).It is observed that there appears to be negligible shift even under the 20 rigorous stability conditions in an open dish. Figure 17 summarizes the lack of effect of API particle size on tablet dissolution in an SKI-606 formulation containing Polyoxyethylene sorbitan monooleate (Tween-80). 25 Figure 18 summarizes dissolution on accelerated stability in bottles with desiccant for the 500 mg strength croscarmellose based formulation (2% binder and 2% intra and extragranular CCS) 500 mg coated in Bottles with Desiccant. There is no shift in dissolution observed at 6M at 40Deg C/75% RH.

WO 2011/002857 PCT/US2010/040555 -13 Figure 19 summarizes dissolution on accelerated stability in bottles without desiccant for the 500 mg strength croscarmellose based formulation (2% binder and 2% intra and extragranular CCS) 500 mg coated in Bottles with Desiccant. There is very little shift in dissolution observed at 6M at 40Deg C/75% RH 5 Figure 20 summarizes dissolution on accelerated stability in bottles with desiccant for the 500 mg strength croscarmellose based formulation (2% binder and 2% intra and extragranular CCS) 100 mg coated in Bottles with Desiccant. There is no shift in dissolution observed at 6M at 40Deg C/75% RH. 10 Figure 21A summarizes Scale-up (100 Kg) batch dissolution stability in Bottles with desiccant. There is minimal to no shift in dissolution on stability in CTAB/acetate buffer (A) and no shift in 0.1 N HCI (B). 15 DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS OF THE INVENTION 1.

Pharmaceutically Acceptable Compositions and Formulations: 15 In certain embodiments, pharmaceutically acceptable compositions of the present invention which comprise SKI-606 and one or more other excipients, such as, for example, one or more binders, carriers, viscosity modifying and suspending agents, wetting agents, wetting agents, sweeteners, pH modifying agents, flavoring agents, preservatives and combinations thereof. One skilled in the art will readily appreciate 20 that the category under which a particular component is listed is not intended to be limiting; in some cases a particular component might appropriately fit it more than one category. Also, as will be appreciated, the same component can sometimes perform different functions, or can perform more than one function, in the context of a particular formulation, for example depending upon the amount of the ingredient and/or the 25 presence of other ingredients and/or active compound(s). In certain embodiments, the present invention provides a pharmaceutically acceptable solid composition comprising: 4-(2,4-dichloro-5-methoxy-phenylamino)-6 methoxy-7-[3-(4-methyl-piperazin-1-yl)-propoxy]-quinoline-3-carbonitrile, also referred to 30 as SKI-606. SKI-606 is described in U.S. Pat No, 6,297,258, along with methods of preparing SKI-606, as described in U.S. Pat. No. 7, 297,795. SKI-606 has the following structure WO 2011/002857 PCT/US2010/040555 -16 CI C O CN

2 0 N O () N N ) SKI-606 Monohydrate and is isolated as a monohydrate. The 3-cyanoquinoline compound, 4-(2,4-dichloro-5 5 methoxy-phenylamino)-6-methoxy-7-[3-(4-methyl-piperazin-1 -yl)-propoxy]-quinoline-3 carbonitrile, is a weak base with an intrinsic solubility of approximately 0.06 pg/mL at pH 8.0. Below pH 8, the solubility of the compound SKI-606 increases exponentially with decreasing pH due to ionization. However, degradation of SKI-606 was observed at low pH aqueous solution through hydrolysis, although the compound is relatively stable at 10 pH higher than 5, when the 4 aminoquinoline group is not ionized. In certain embodiments, the inventive SKI-606 formulation obviates one or more problems with solid formulations of 3-cyanoquinolines including variable dissolution, which appears to depend on particle size, accelerated dissolution on storage, and 15 limited stability upon storage. The inventive croscarmellose SKI-606 formulations exhibit disintegration times (of 2-7 minutes) faster than comparable SKI-606 formulations employing a conventional disintegrating agent (e.g. crospovidone, disintegration times about 18-20 minutes). 20 In certain embodiments, the inventive SKI-606 formulation comprises a film coated SKI-606 formulation that is prepared by high shear wet granulation or pan coating. In other embodiments, the film coated SKI-606 tablet formulation is prepared by other conventional coating techniques. 25 Disintegration times were compared for SKI-606 formulation using a conventional disintegrating agent, crospovidone, and croscarmellose sodium and summarized in Table 2. The intragranular disintegrant in this case was kept constant at 3 % w/w. The two formulations have markedly different disintegration times, for instance tablet disintegration times (DT) with the 2% extragranular (EG) SKI-606/CCS formulation is WO 2011/002857 PCT/US2010/040555 -17 only 3.5 minutes as compared to the SKI-606/CPV formulation with a DT of 22 minutes. Additionally it is also observed that tablet DT is strongly dependent on tablet hardness for all the SKI-606/CPV formulations, whereas no such dependence is observed for the SKI-606/CCS formulations. For instance, even for the 3% IG and 2% EG SKI-606/CPV 5 formulation, the DT times for the low and the high hardness tablets vary by 14 minutes (range), whereas the SKI-606/CCS formulations only vary by 3.5 minutes. This observation indicates that the SKI-606/CCS formulation was robust with respect to tablet hardness, a significant improvement with respect to tablet manufacturability characteristics of the inventive SKI-606 formulation. 10 Tablet dissolution of the inventive SKI-606 formulation (see Figure 1) was also carried out in 0.1 N HCI, which revealed that the tablet dissolution was faster for the SKI-606/CCS formulations at the 10 and 15 minutes at disintegrant concentrations lower than the ones used for SKI-606/CPV formulations. In addition the data also suggested 15 that the lower binder concentrations enhanced dissolution especially at early time points. In certain embodiments, amounts of croscarmellose sodium (CCS) in the inventive SKI-606 formulation that provide similar dissolution results are as follows: 20 1. 0- 2 % w/w intragranular concentration 2. 1-3% w/w extragranular concentration 3. Binder (Povidone concentrations) may also vary from 1-2% w/w. In certain embodiments, the intragranular component to extragranular component 25 ratio in the inventive SKI-606 formulation was changed from 3:1 to 2:2. In certain embodiments, one intragranular (IG) component, a filler comprising microcrystalline cellulose (MCC), was transferred from the intragranular portion to the extragranular (EG) component to facilitate faster disintegration times during tabletting in 30 the inventive SKI-606 formulation. The amount of extragranular filler component was increased to 15 weight % from 4 weight %, based on the weight of the SKI-606 formulation.

WO 2011/002857 PCT/US2010/040555 -18 In certain embodiments, the grade of MCC in the EG component was changed from Avicel PH101TM to Avicel PH 102TM to facilitate tablet blend flow. In certain embodiments, contrary to the common observation that reduction in 5 particle size of the API generally causes an increase in rate of dissolution, it was observed that for SKI 606 formulation, decreasing the API particle size tends to lower the dissolution of the formulation when processed in a n identical fashion as the formulation with higher D90 API particle size. Thus it was observed that that the lower the API particle size, the slower the dissolution rate and higher the API particle size 10 faster the rate of dissolution, as summarized in Figure 6. In order to maximize dissolution, one possible approach with the existing formulation is to increase the particle size of the drug like SKI-606. To slow down in dissolution an approach is to use API of lower particle size. 15 In certain embodiments, no change in the poloxamer concentration was made in the inventive SKI-606 formulation to retain in vivo effects when administered to a human or animal subject. 20 In certain embodiments, the formulation of the present invention can contain one or more non-rate-controlling layers, membranes or coatings. The location of the non rate-controlling layer in the formulation is not critical. For example, the non-rate controlling layer may be present between the at least one core and an enteric coating or a rate-controlling mechanism. Alternatively, the non-rate-controlling layer may surround 25 or coat an enteric coating or a rate-controlling mechanism. The non-rate-controlling layer can be made of one or more polymers, as well as, other ingredients known in the art, such as, but not limited to, plasticizers, pigments/opacifiers, etc. Examples of polymers that can be used include, but are not limited to, hydroxypropyl methylcellulose, hydroxypropyl cellulose, methylcellulose, ethylcellulose, polyvinyl alcohol, and 30 polyethylene glycol. Examples of plasticizers that can be used include, but limited to, polyethylene glycol(s), glycerin, triacetin, triethyl citrate, diethyl phthalate and mineral oils. Examples of pigments/opacifiers that can be used include, but are not limited to, water soluble dyes, pigments, and natural products.

WO 2011/002857 PCT/US2010/040555 -19 In certain embodiments, the formulations of the present invention can also include at least one enteric coating. Any enteric coating can be used in the present invention, including, but not limited to, solutions or dispersions of methacrylic acid and methacrylic ester copolymers, cellulose acetate phthalate, hydroxypropyl 5 methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, polyvinyl acetate phthalate, ethyl acrylate/methacrylic acid copolymers, cellulose acetate trimellitate, shellac and combinations thereof. Additionally, the enteric coating used in the formulations of the present invention can be formed as a single or multiple layers. The thickness of the coating can be readily determined by those skilled in the art, but 10 must be sufficient to protect the formulation in the acidic environment of the stomach. In certain embodiments, solid pharmaceutically acceptable compositions of SKI 606 were invented, based on replacing one conventional disintegrating agent, crospovidone, with croscarmellose sodium, which unexpectedly resulted improved 15 stability and uniform dissolution rate of the SKI-606 formulation (see Table 1 and Figures 1-3).

Dosage forms suitable for internal use comprise from about 0.5 to 1000 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For WO 2011/002857 PCT/US2010/040555 -22 example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation. In some embodiments, pharmaceutical compositions of SKI-606 from the 5 standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. In a preferred embodiment, Oral administration of SKI-606 is preferred. 10 For the treatment of cancer, the inventive SKI-606 formulations of this invention can be administered in combination with other anti-tumor substances or with radiation therapy.

WO 2011/002857 PCT/US2010/040555 -25 All features of each of the aspects of the invention apply to all other aspects mutatis mutandis. Examples I and 2: Preparation of Pharmaceutically Acceptable Compositions of SKI-606 SKI-606 is prepared according to the methods described in detail in one or more 5 of U.S. Pat Nos. 6,297,258 and 7,297,795. An exemplary inventive formulation of SKI 606 and a comparative SKI-606 formulation are summarized in Table 1. Table 1. SKI-606 Formulations Comparative SKI-606 SKI-606 Formulation 1 formulation Intragranular Components (% wiw) (% wiw) SKI-606 monohydrate (equivalent to SKI-606 free base) 69 69 Microcrystalline Cellulose (MCC, Avicel PH101 T M ) 6.5 17.5 Crospovidone (CPV) NA 3 Croscarmellose Sodium (CCS) 2 NA Poloxamer 188TM (Lutrol F-68) 3 3 Povidone (Kollidon 25TM) 2 2 Weight % Intragranular Components 82.5 94.5 Extragranular Components Microcrystalline Cellulose (MCC, Avicel 101TM) NA 4 Microcrystalline Cellulose (MCC, Avicel 102TM) 15 NA Crospovidone NA 1 Croscarmellose Sodium 2 NA Magnesium stearate 0.5 0.5 Weight % Extragranular Components 17.5 5.5 Coating (Opadry || systems) 3 4 10 NA-not applicable or not available Tablets of the 500 mg strength were compressed using the appropriate tooling equipment and the tablets were compressed at low (11-13kp), target (14-16 kp) and WO 2011/002857 PCT/US2010/040555 -26 high (17-19 kp) hardnesses. These tablets were then evaluated for disintegration time in 0.1 N HCI. The comparative SKI-606 formulation was prepared by the process of high shear 5 wet granulation, wet milling, fluidized bed drying, dry milling, blending and compression to tablets that are subsequently film coated. This formulation has been associated with high percentage of gastric irritation in fasted individuals. Disintegration times were compared for SKI-606 formulation using a conventional 10 disintegrating agent, crospovidone, and croscarmellose sodium and summarized in Table 2. The intragranular disintegrant in this case was kept constant at 3% w/w. The two formulations have markedly different disintegration times, for instance tablet disintegration times (DT) with the 2% extragranular (EG) CCS formulation is only 3.5 minutes as compared to the CPV formulation with DT of 22 minutes. Additionally it is 15 also observed that tablet DT is strongly dependent on tablet hardness for all the CPV formulations, whereas no such dependence is observed for the CCS formulations. For instance, even for the 2% CPV formulation, the DT times for the low and the high hardness tablets vary by 14 minutes, whereas the CCS formulations only vary by 3.5 minutes. This observation points to the fact that the CCS formulation was robust with 20 respect to tablet hardness. This is a significant improvement with respect to tablet manufacturability characteristics, especially since the tablets are meant to be immediate release tablets.

In addition the data also suggested that the lower binder concentrations enhanced dissolution especially at early time points. These trials demonstrate that CCS formulation was better from processability point in that granulation endpoint was not reached suddenly unlike CPV formulations 10 where endpoint was very susceptible to water input, and CCS formulation disintegration time (DT) was less susceptible to tablet hardness. Lowering of binder may correlate to adequate dissolution with CPV. It is also evident that for the inventive SKI-606 formulation, which included 15 croscarmellose sodium as a disintegrant, the dissolution is not sensitive to API particle size at 15 minutes, as summarized in Table 3. In addition for all IG/EG ranges studied, the only ratio that gave slower dissolution for CCS formulation at 15 minutes is 1%/0 % intra/extragranular disintegrant. For all other levels, release is more than 90%.

The change in binder was not deemed necessary for the CCS formulation that shows excellent tablet disintegration times and dissolution regardless of the binder concentration. 10 The results of extensive experimentation demonstrated that croscarmellose sodium formulations were more robust with respect to variability in drug substance particle size and consistency of dissolution profile for product on stability. Some advantages were seen bychanging the intra to extragranular ratio of microcrystalline 15 cellulose to improve both tablet disintegration times as well as blend flow, and keeping the poloxamer and the binder same as the reference composition. It is also evident that for the inventive SKI-606 formulation which included croscarmellose sodium as a disintegrant, the dissolution is slower for smaller particle 20 size, as summarized in Tables 2 and 3. In addition, it was observed that no incompatibilities or degradation were seen at 2 and 4 weeks with either disintegrant at 400 C (dry and wet). Batches on stability studies at 400 C and 400 C /75% RH conditions showed that dissolution shifts observed with CPV, but not with CCS, as summarized in Figures 2 and 3. 25 WO 2011/002857 PCT/US2010/040555 -30 Based on the measured data and results, the croscarmellose formulation is seen to provide superior SKI-606 tablet formulations, as API variability effect on dissolution and dissolution shift on stability areboth addressed, while making minimal changes to the formulation (It was thus decided to keep the binder povidone and poloxamer 5 constant at 2% and 3% respectively.) Disintegrant type and the IG/EG disintegrant ratio was changed from 3:1 in clinical to 2:2 (% w/w). Figures 4 and 5 describe the effect on disoolution by changing the intra and extragranular disintegrant ratios for both croscarmellose and Crospovidone respectively. 10 Example 3: Preparation of Fast Dissolving Pharmaceutically Acceptable Compositions of SKI-606 SKI-606 is prepared according to the methods described in detail in one or more of U.S. Pat Nos. 6,297,258 and 7,297,795. An exemplary inventive fast dissolving formulation of SKI-606 and a comparative SKI-606 formulation are summarized in Table 15 4. Table 4.

The inventive SKI-606 formulation also provides a relatively fast dissolving salt of the drug that solubilizes faster in the GI tract. The fast dissolving salts of the drug includes the citrate, succinate, fumarate, Di HCI, Di- mesylate, acetate, maleate, tartarate and HCI salts to name a few, providing a 10 SKI-606 formulation useful for dissolving or disintegrating faster within the GI tract to cause rapid drug dissolution. A faster disintegrating formulation was prepared by making a few changes to the current formulation. This was done by incorporating the following changes in the 15 formulation: eplacing the disintegrant crospovidone with croscarmellose sodium. This disintegrant acts by a "swelling" action promoting early disintegration times as compared to the "wicking" action promoted disintegration with the crospovidone. It is found to exert a faster disintegrant action at comparable concentrations as the crospovidone.In addition to replacing the disintegrant, an additional change done was the change in the 20 ratio of the microcrystalline cellulose. Microcrystalline cellulose, Avicel PH 101 was reduced intragranularly and increased extragranularly to help improve the disintegrant efficacy. The grade was also changed from Avicel 101 to a larger particle sized 102 to improve blend flow and compressibility. This approach was found to yield faster disintegrating and dissolving tablets, both of which are expected to improve the gastric 25 outcome in the stomach. The inventive SKI-606 formulation is based on this approach.

WO 2011/002857 PCT/US2010/040555 -37 Compress tablets at known weights and hardnesses and film coated compressed tablets. In certain embodiments, the inventive SKI-606 formulation obviates one or more problems with solid formulations of 3-cyanoquinolines, namely, variable dissolution and 5 a tendency for certain SKI-606 formulations (see comparative Example) to undergo small yet significant shifts on in dissolution on aging at both room temperature and under accelerated conditions when tested in buffer solution or under acidic conditions, as summarized in Figures 10 and 12. Figure 11 shows the lack of dissolution shift for the croscarmellose formulation. Figure 12 shows the dissolution shifts in existing 10 formulation. The poloxamer 188 in the SKI-606 comparative formulation was responsible for the shift in dissolution observed. Poloxamer though a solid at room temperature tends to undergo liquefaction at and around temperatures near its melting point of 48-520 C. Studies summarized in Figures 13 and 14 revealed that the poloxamer in the Crospovidone based formulation was indeed the reason that the 15 tablets were shifting in dissolution. In certain embodiments, SKI-606 tablet formulations were prepared with varying amounts of poloxamer, ranging from 0, 1.5, 3, 4.5 and 6% w/w, based on the weight of the SKI-606 formulation. Unexpectedly. it was observed that there existed a clear 20 dependency of tablet dissolution on the percent poloxamer content of the formulation, when tested in 0.1 N HCI. Figure 13 summarizes the effects of varying poloxamer content on tablet dissolution at similar water and binder addition rates in 0.1 N HCI. It is observed that the poloxamer actually appears to retard the release especially at early time points for the tablets tested. Poloxamer appeared to retard initial tablet dissolution 25 at 15 and 30 minutes in a concentration dependent manner. See Table 8. Table 8: Disintegration times in 0.1 N HCI of SKI-606 500 mg Tablet Cores with Varying Poloxamer content Poloxamer concentration DoE-1/Run Number Tablet DT range [N=6) (% w/w) (min) 0 2 6.2-6.6 1.5 1 10.6-12.9 3.0 3 11.5-13.1 4.5 7 14.1-15.6 6.0 5 14.3-14.9 WO 2011/002857 PCT/US2010/040555 -38 Although the poloxamer in tablets tends to retard dissolution initially, it was found to speed up dissolution on accelerated stability at later timepoints in 0.1 N HCI media as seen in the data summarized in Table 9. Table 9: Increase in Percent dissolved for the DoE batches in 0.1 N HCI and pH 4 Buffer (Stability Studies) Water Binder addition Poloxamer (% Release at 15 min (%) in 0.1 N HCI (G) rate (g/min) w/w) (+ -Increase in % dissolution from initial) 147 58.5 0 Initial 66 1M@40 Deg C +3 1 M@40 Deg C/75% RH +6 162 58.5 1.5 Initial 50 1M@40 Deg C +19 1 M@40 Deg C/75% RH +22 147 58.5 3.0 Initial 43 1M@40 Deg C +11 1 M@40 Deg C/75% RH +31 158 66 4.5 Initial 38 1M@40 Deg C +13 1 M@40 Deg C/75% RH +8 147 58.5 6.0 Initial 38 1M@40 Deg C +6 1M@40 Deg C/75% RH +14 5 On accelerated stability, poloxamer causes a dissolution shift in a concentration dependent manner from 0 to 3% w/w. The dissolution shift beyond 3% poloxamer concentration plateaus off with no evident trends. These results verify that the poloxamer can cause dissolution shifts to happen on stability. The poloxamer chains on 10 aging and at accelerated temperatures are believed to become more mobile, and thus instead of holding the granules together in the tablet the mobile polymer chains tends to "soften" the tablets. This could be as a result of granule softening over time as well as WO 2011/002857 PCT/US2010/040555 -39 increased tendency to disintegrate. Also seen are lowered disintegration times on stability. Once the tablet has disintegrated the granules in the tablet actually show behavior very similar to all known surfactants. Increase in surfactant tends to increase granule dissolution as seen in Figure 14. 5 This dissolution shift problem was obviated by the inventive SKI-606 formulation, by replacing the wetting agent poloxamer, which also functions as a surfactant, in the formulation. The use of a lower melting point surfactant (one that was liquid at room temperature) could help to address this issue. Polyoxyethylene (20) sorbitan 10 monooleate (TweenTM or polysorbate 80TM i) is one of the commonly used surfactants in use. The concentration of Polyoxyethylene (20) sorbitan monooleate (Polyoxyethylene sorbitan monooleate (Tween-80)TM) tested was 1 % in place of the 3% poloxamer in the formulation. This was used in the CPV formulation with 3% IG and 1% EG CPV as the disintegrant. This was deemed acceptable as the dissolution and other manufacturability 15 characteristics tested at this concentration were acceptable. In addition, Polyoxyethylene sorbitan monooleate (Tween-80)TM is a commonly used pharmaceutically acceptable wetting agent and also functions as a surfactant. In addition to addressing dissolution shift, testing of the robustness of these 20 formulations with respect to active pharmaceutical ingredient API particle size is desirable. The comparative SKI-606 formulation the API particle size appeared to influence the dissolution i.e. smaller the API particle size, slower the dissolution. With the SKI/Tween-80 formulation, this effect was minimized or negligible (Figure 17) and the SKI-606 formulations comprising the alternative wetting agent Polyoxyethylene 25 sorbitan monooleate (Tween-80) T M were superior in aging (Figures 15 and 16) to the comparative SKI-606 formulation Examples 11 and 12: Preparation of Pharmaceutically Acceptable Compositions of SKI-606 30 SKI-606 is prepared according to the methods described in detail in one or more of U.S. Pat Nos. 6,297,258 and 7,297,795.
