COMPOSITIONS AND METHODS FOR PREPARING IMMEDIATE
RELEASE FORMULATIONS OF NILOTINIB
Cross Reference to Related Applications
This patent application claims priority to Indian application number 1887/CHE/201 1, filed on June 2, 201 1, the contents of which are incorporated by reference herein in their entirety.
Field of Disclosure
The present disclosure relates to pharmaceutical compositions of kinase inhibitors. More particularly, the present disclosure relates to immediate release compositions of nilotinib or its pharmaceutically acceptable salts and process for preparing the same.
Background of Disclosure
Nilotinib belongs to pharmacologic class of drugs known as kinase inhibitors. Chemically Nilotinib is 4-methyl-N-[3-(4-methyl-lH-imidazol-l-yl)-5-(Triflouro methyl) phenyl]-3-[[4-(3-pyridinyl)-2-pyrimidinyl] amino] -Benzamide having molecular formula, C28H22F3N70,HC1*H20 with a molecular weight of 565.98. The structural formula is:
Figure imgf000002_0001
Nilotinib is indicated for the treatment of newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase and accelerated phase by inhibition of tyrosine kinase (TK) activity of Bcr-Abl in adult patients.
Nilotinib hydrochloride is marketed as 150 mg and 200 mg oral capsules in United States under the trade name, TASIGNA® by Novartis.
US7169791 discloses 4-Methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl] amino]-N- [5-(4-methyl-lH-imidazol-l-yl) -3-(trifluoromethyl) phenyl] benzamide and its use for the treatment of leukemia by inhibition of protein kinase activity.
US2010087463 discloses pharmaceutical compositions of nilotinib prepared by wet granulation process.
WO2009100176 discloses solid dispersion product of tyrosine kinase inhibitor using polymers and so lubilizers. US20080269269 discloses different polymorphs such as pure crystalline Form
A, B, C and D of nilotinib, nilotinib hydrochloride and substantially pure amorphous form of nilotinib hydrochloride.
US2010190812 discloses crystalline nilotinib hydrochloride.
Wet granulations, however, require the drug to be exposed to water and/or solvents. Such an exposure increases the risk that the solid-state form of the nilotinib would change (e. g., crystallize or change in polymorphic form or hydrated forms etc) or degrade chemically. Since amount of liquid addition and rate will depend on factors such as the volume and surface area of the wet granulation vessels, the exact particle sizes of the drug and excipients used in a specific manufacturing run, there can be difficulties in scaling-up wet granulation processes. Wet granulation is a process of using a liquid binder to lightly agglomerate the powder mixture. The amount of liquid has to be properly controlled, as over-wetting will cause the granules to be too hard and under-wetting will cause them to be too soft and friable. Solute migration during drying may be an issue, especially for soluble drug substances. The major disadvantage of wet granulation may be its complexity because it involves several steps and many parameters to be controlled and is expensive.
Therefore there remains a need to provide dry granulation compositions as well as mixing and filling compositions for nilotinib such that flow of said composition is acceptable for commercial unit dosage formulation, having good dissolution rates and bioavailability where in drug will not be exposed to the solvent. Summary
It has been surprisingly found that compositions of the present invention prepared by dry granulation process as well as simple mixing and filling using nilotinib as the active ingredient, exhibited excellent dissolution characteristics that were also found to be comparable with to the marketed formulation. In addition dry granulation and simple mixing and filling are robust (scalable) process, therefore cost effective.
In one embodiment, the present disclosure provides a dry-granulated pharmaceutical composition comprising nilotinib or a pharmaceutically acceptable salt thereof. Further embodiment of the present disclosure provides compositions comprising nilotinib and at least one excipient selected from a diluent, a binder, a disintegrant, a surfactant, a glidant and a lubricant.
In another embodiment, present disclosure provides composition comprising: i) nilotinib or a pharmaceutically acceptable salt thereof, ii) a water soluble polymer selected from polyethylene glycol, polyvinyl pyrrolidone, polyethylene oxides, alkyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose or mixtures thereof, and iii) one or more excipients selected from a diluent, a binder, a disintegrant, a surfactant, a glidant and a lubricant.
In one embodiment, provides a process for preparing compositions comprising nilotinib and one or more pharmaceutically acceptable excipients followed by mixing and filling into capsules or subjected to dry granulation.
In another embodiment, present disclosure provides a process for preparing dry-granulated pharmaceutical composition of nilotinib comprising compacting nilotinib hydrochloride alone or mixing with one or more of pharmaceutically acceptable excipient(s) by roller compactor or slugging; sizing the compacts or slugs into granules by milling; mixing the granules with one or more of pharmaceutically acceptable excipients to form the composition.
In another embodiment, present disclosure provides a process for preparing pharmaceutical composition of nilotinib comprising: (i) mixing nilotinib and one or more pharmaceutically acceptable excipients to form dry mixture; (ii) followed by filling the dry mixture of step (i) into capsules.
In an embodiment, the present disclosure also provides composition comprising nilotinib hydrochloride, microcrystalline cellulose, poloxamer, hydrophobic colloidal silica and magnesium stearate.
In yet another embodiment, the method of treating Philadelphia chromosome positive chronic myeloid leukemia comprising administering a therapeutically effective amount of a pharmaceutical composition comprising nilotinib or a pharmaceutically acceptable salt thereof.

A binder also sometimes called an adhesive, can be added to a drug-filler mixture to increase the mechanical strength of the granules and tablets during formation. Suitable binders include starch, microcrystalline cellulose, gelatin, polyvinylpyrrolidone, and sugars such as sucrose, glucose, dextrose, lactose, polyvinyl alcohol and mixtures thereof.
One or more disintegrants are included in the^ compositions to ensure that the formulation has an acceptable dissolution rate in an environment of use such as the gastrointestinal tract. Efficacy of a drug mixture can be dependent on the rate at which the tablet or capsule disintegrates in the patient's gastrointestinal tract. Typically, disintegrants expand, swell, and dissolve when wet, causing the tablet or granule to break apart in the digestive tract, releasing the active ingredients and excipients for absorption. Examples of disintegrants suitable for use herein include, but are not limited to croscarmellose sodium, crospovidone, starch, potato starch, pregelatinized starch, corn starch, sodium starch glycolate, microcrystalline cellulose, low substituted hydroxypropyl cellulose and other known disintegrants.
Suitable surfactants for example include, but are not limited to, polyoxyethylene-polyoxypropylene block copolymers (also known as poloxamers), soluplus (a graft copolymer comprised of polyethylene glycol, polyvinylcaprolactam and polyvinylacetate), sodium lauryl sulfate, sodium stearyl sulfate, sodium oleyl sulfate, sodium cetyl sulfate, sodium dodecylbenzene sulfonate, dialkyl sodium sulfosuccinates, polyethylene glycols and polysorbates. The present invention particularly provides a pharmaceutical composition comprising nilotinib, having 0.1 to 2 % of surfactant based on total weight of the composition.
One or more glidants may be used in compositions to improve flow in low concentrations. Suitable glidants for example include but are not limited to silicon dioxide, colloidal silicon dioxide, magnesium silicate, magnesium trisilicate, talc, and other forms of silicon dioxide, such as aggregated silicates and hydrated silica.
Lubricants can be added to pharmaceutical compositions to decrease any friction that occurs between the solid and the die wall during manufacturing of formulations. Suitable lubricants include but not limited to fatty acids, fatty acid salts, and fatty acid esters such as magnesium stearate, calcium stearate, stearic acid, sodium stearyl fumarate, hydrogenated vegetable oil and the like.
The present invention also provides composition comprising: i) nilotinib or its pharmaceutically acceptable salts, ii) water soluble polymer iii) and optionally one or more excipients selected from a diluent, a binder, a disintegrant, a surfactant, a glidant, and a lubricant.
Water soluble polymer as per the instant invention increase the rate of drug release from its dosage form, which include and is not limited to polyethylene glycol, polyvinyl pyrrolidone, polyethylene oxides, alkyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose or mixtures thereof.
The present disclosure provides process for preparing compositions of nilotinib using dry granulation process.
The present disclosure further provides process for preparing compositions of nilotinib by mixing nilotinib hydrochloride with one or more excipients and filling into capsules. Dry granulation process according to the present invention involves either slugging or roller compaction.
Slugging is a double compression process in which the material to be processed is compressed to a large compressed mass, or "slug," which is further milled to form granules and are finally filled into capsules or compressed into tablets. The process includes (i) sifting and blending of dry mix ingredients; (ii) compressing the blend of step (i) to obtain slugs; (iii) milling and sifting the step of (ii) to obtain granules; (iv) lubricating and blending the granules of step (iii) and finally filling into capsules or compressing into tablets. The term "roller compaction" as used herein refers to a process by which two or more solid materials are compacted between two rotating rolls, desirably, counter- rotating rolls to form solid ribbons/ compacts and the resulted compacts are sized into granules by milling to modify the desired particle size; optionally mixing the granules with one or more of pharmaceutically acceptable excipients to form the composition. A process for preparing dry-granulated pharmaceutical composition of nilotinib comprises compacting nilotinib hydrochloride alone or mixing with one or more of pharmaceutically acceptable excipient(s) by roller compactor or slugging; •sizing the compacts or slugs into granules by milling; mixing the granules with one or more of pharmaceutically acceptable excipients to form the final composition. Mixing process includes: (i) sifting and blending of nilotinib hydrochloride with one or more pharmaceutically acceptable excipients to form a dry mixture; (ii) followed by filling the dry mixture of step (i) into capsules.
Another embodiment provides composition comprising nilotinib hydrochloride, microcrystalline cellulose, poloxamer, hydrophobic colloidal silica and magnesium stearate.
