## Background
PRIORITY TO RELATED APPLICATION(S)
This application claims the benefit of European Patent Application No. 10190045.4, filed Nov. 4, 2010, which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
Active pharmaceutical ingredients showing an ester, amide or thioester functionality are often sensitive to moisture and frequently show chemical incompatibility with a wide range of commonly used pharmaceutical excipients, thus typical formulation approaches such as lipid based drug delivery systems can not be considered. Incorporating the drug substance into a hygroscopic polymer matrix can be critical due to chemical as well as physical stability. The sorption of moisture by excipients in solid dosage forms can lead to considerable stability problems when the contained active pharmaceutical is instable in water due to the presence of a hydrolysis sensitive functional group. Though theoretically hygroscopic polymers are capable to bind moisture in the formulation, thus protecting the active pharmaceutical ingredient from hydrolysis, a fairly high amount of polymer is needed to achieve this what usually leads to capping or cracking of the immediate-release tablet formulation. Thus, it is usually imperative to prevent moisture sorption during storage by both, a suitable formulation and primary packaging.
SUMMARY OF THE INVENTION
The present invention relates to a hygroscopic matrix based formulation, a process for the preparation thereof and its use in the treatment of diseases.

DETAILED DESCRIPTION OF THE INVENTION
Unless otherwise stated, the following terms used in the specification and claims have the meanings given below:
The term “bulk density” refers to a density measurement of a loose, uncompacted substance, wherein the volume of the substance includes the air trapped between particles. The bulk density is measured in a graduated cylinder according to the European Pharmacopeia.
The term “diluent” refers to an excipient which fills out the size of a tablet or capsule, making it practical to produce and convenient for the consumer to use. Suitable diluents include e.g. pharmaceutically acceptable fillers, such as microcrystalline cellulose (e.g. Avicel®), crospovidone micronized, cellulose powder, lactose spray-dried, lactose anhydrous, lactose monohydrate, dibasic calcium phosphate, sugars, sugar alcohols, corn starch, starch, pregelatinized starch, colloidal silicon dioxide, polysaccharides, and mixtures thereof.
The term “hydrophobic” means insoluble in water, not readily absorbing moisture, or being adversely affected by water; either incompatible with water or having little affinity for it. In other words the hydrophobic drug or compound would not spontaneously disperse in water. Specifically hydrophobic means log P>3. The log P is measured or in the absence of experimental data calculated as clog P according to the model developed by Moriguchi (S. Moriguchi, S. Hirono, I. Nakagome, H. Hirano, (1994). “Comparison of reliability of log P values for drugs calculated by several methods” Chem Pharm Bull 1994, 42:976-978).
The term “hygroscopic polymeric excipient(s)” means polymeric excipient(s) which take(s) up moisture for example by absorption or adsorption even at relative humidity as low as 50%, at room temperature (e.g. about 25° C.). The moisture uptake is measured e.g. by dynamic vapor sorption at room temperature. As an example the hygroscopicity can be measured in accordance with the method disclosed in the European Pharmacopoeia—6th Edition (2008), Chapter 5.11. The dynamic vapor sorption technique measures the change in mass which is produced by varying the vapor concentration surrounding the product. Suitable “hygroscopic polymeric excipients” are hydroxypropyl methylcellulose, hydroxypropyl cellulose, low-substituted hydroxypropyl cellulose, hydroxyethylmethyl cellulose, carboxypolymethylene, methylcellulose, ethylcellulose, hydroxyethyl cellulose, celluloseacetate, polyvinylpyrrolidone crosslinked polyvinylpyrrolidone, micronized crosslinked polyvinylpyrrolidone, carboxymethylcellulose sodium, carboxymethylcellulose calcium, crosslinked carboxymethylcellulose, microcrystalline cellulose, silicified microcrystalline cellulose, cellulose powder, carboxymethyl starch, starch, pregelatinized starch or mixture thereof. In particular “hygroscopic polymeric excipients” refer to hydroxypropyl methylcellulose, carboxymethylcellulose sodium, microcrystalline cellulose and micronized crosslinked polyvinylpyrrolidone. Examples of “water insoluble hygroscopic polymers” at room temperature (e.g. about 25° C.) include low-substituted hydroxypropyl cellulose, carboxypolymethylene, ethylcellulose, celluloseacetate, crosslinked polyvinylpyrrolidone, micronized crosslinked polyvinylpyrrolidone, carboxymethylcellulose calcium, microcrystalline cellulose, silicified microcrystalline cellulose, cellulose powder, and starch.
The term “Super-disintegrant” refers to disintegrants that very rapidly expand upon contact with water. Generally speaking, superdisintegrants are disintegration agents which can be used in a fractional amount of normal disintegrants to obtain the same effect. Examples of superdisintegrants include cross-linked carboxymethyl cellulose sodium (a.k.a. croscarmellose sodium), sodium starch glycolate, and cross-linked polyvinyl pyrollidone (a.k.a. crospovidone). Croscarmellose sodium is commercially available from FMC Corp. under the trade name Ac-Di-Sol® and from Avebe Corp. under the trade name Primellose®®. Sodium starch glycolate is commercially available from Penwest Pharmaceuticals Co. under the trade name Explotab® and from Avebe Corp, under the trade name Primojel®. Crospovidone is commercially available from BASF Corp. under the trade name Kollidon® CL and from International Specialty Chemicals Corp. under the trade name Polyplasdone®, Croscarmellose is also commercially available from Mingtai Chemical Co. Ltd under the trade name DISOLCEL® and from J. Rettenmaier & Söhne GmbH+Co (JRS) under the trade name Vivasol®. The most preferred superdisintegrants are croscarmellose sodium and crospovidone.
The term “water instable” means the presence of a hydrolysis sensitive functional group like an ester, amide or thioester.
The term “waxy consistency” means that the glass transition temperature (Tg) is lower than 25° C.
The term “halo” means chloro, bromo, iodo or fluoro.
“Aryl” means a monovalent monocyclic or bicyclic aromatic hydrocarbon moiety. More specifically the term aryl includes, but is not limited to, phenyl, 1-naphthyl, 2-naphthyl, and the like, each of which can be substituted or unsubstituted.

Usually bringing a moisture sensitive active pharmaceutical ingredient in contact with a high amount of hygroscopic polymers such as HPMC, HPC, PVP, Crospovidone, CMC, crosslinked CMC and MC is considered critical to physical stability.
Surprisingly it was found that in case of the hydrophobic hydrolysis sensitive CETP inhibitor a converse effect could be observed. It was possible to stabilize both, the active pharmaceutical ingredient and the immediate release tablet by embedding the active in a hygroscopic polymeric matrix comprising of:












Relative amount of tablet core


Ingredient
[%]
















CETP inhibitor thiosester
>50%


Water insoluble, hygroscopic polymer
>40%


Water soluble, hygroscopic polymer
>4%


Other Excipients
<6%









Furthermore, it was surprisingly found that increasing the amount of hydroscopic polymers from its usual range of 10 to 20% by weight to more than 30% by weight in the presence of hydrophobic compound did not lead to capping or cracking of the immediate-release tablet formulation as would have been expected. Therefore, the hydrophobic compound prevents the formation of cracks of the immediate release tablet when more than 30% by weight of the tablet consists of hygroscopic polymeric excipients.

Manufacturing Process:
Herein, the API refers to the active substance which is hydrophobic, water instable compound with a waxy consistency, in particular to a CETP inhibitor thiosester derivative, more particularly to a CETP inhibitor thiosester derivative of formula (I) or (I′). In the examples 1 to 45, the API refers to thioisobutyric acid S-(2-{[1-(2-ethyl-butyl)-cyclohexanecarbonyl]-amino}-phenyl)ester of formula (I′) in crystalline form.
The composition of the present invention may be prepared according to any known process which results in keeping the API substantially in crystalline form (the amount of the hydrophobic, API in amorphous does not exceed 10% by weight). Furthermore, the composition of the present invention may be prepared according to any known process which results in keeping the API substantially in crystalline form (the amount of the hydrophobic, water instable compound with a waxy consistency substantially in amorphous does not exceed 10% by weight).
The process for preparing a pharmaceutical composition according to the present invention may comprise the following steps:
1) dissolving hydroxypropylmethyl cellulose (0.5% by weight of total hydroxypropylmethyl cellulose) in 20% ethanol by weight and 80% water by weight under constant stirring;
2) loading granulator (high shear mixer: e.g. Diosna®) vertical granulator with bottom driven impeller, with a hydrophobic, water instable compound with a waxy consistency, crospovidone micronized, microcrystalline cellulose, croscarmellose sodium and remainder of hydroxypropylmethyl cellulose;

3) mixing the dry granulate components using impeller and chopper;

4) humidifying the granulate by spraying of the granulation fluid under constant mixing using impeller and chopper;

5) kneading the wetted granulate using impeller and chopper;

6) discharging the wet granulate, screening it over a conical mill [e.g. Frewitt® (screening mill with rotating impeller)); fitted with a 10 mm square screen and loading it into the fluid bed dryer

7) drying the granulate in the fluid bed dryer (e.g. Glatt®) with inlet air temperature ≦60° C. until the final LOD (loss on drying) of ≦3.5% by weight is reached;

8) discharging the dried granulate and milling it using an impact mill fitted with a 1.5 mm round perforation screen (e.g. Frewitt® (impact mill with rotating hammer);

9) adding the components of the external phase (e.g. microcrystalline cellulose, colloidal silicon dioxide and sodium stearylfumarate) over a sieve fitted with a 1 mm round perforation screen to the granulate

10) blending all the components in a bin blender (e.g. Tumblemix® (tumble blending in bin blender));

11) compressing the tablets on a rotary tablet press with low compression force (around 6 kN), (e.g. Korsch® (power assisted);

12) preparing the coating suspension by suspending Opadry® complete coating system in water under constant stirring;

13) loading the tablets into the perforated coating pan;

14) preheating the tablets with inlet air ≦60° C. until a tablet temperature of around 43° C. is reached under constant rotation of the perforated coating pan (e.g. Glatt® (perforated coating system));

15) spraying the coating suspension onto the tablets under constant rotation of the perforated coating pan;

16) drying the film-coated tablets under constant rotation in the perforated coating pan;

17) discharging the film-coated tablets.

Example B
Two tablets produced according to example 1 and example A were sliced and their X-ray pictures were collected. Both figures represent an overlayed of all X-ray slices that were generated during the measurement to reconstruct the 3D tablet. While FIG. 1 does not show any imperfection but a smooth surface, FIG. 2 has lot of cracks. These crack are also detectable by the human eye.
Example C
XRPD patterns of S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate crystalline form A were recorded at ambient conditions in transmission geometry with a STOE STADI P diffractometer (Cu K alpha radiation source, primary monochromator, position sensitive detector, angular range 3° to 42° 2 Theta, approximately 60 minutes total measurement time). The samples were prepared and analyzed without further processing (e.g. grinding or sieving) of the substance.
