The present invention relates to solid dispersions comprising an apoptosis-inducing agent, to pharmaceutical dosage forms comprising such dispersions, to processes for preparing such dispersions and dosage forms and to methods of use thereof for treating diseases characterized by overexpression of anti-apoptotic Bcl-2 family proteins.
Overexpression of Bcl-2 proteins correlates with resistance to chemotherapy, clinical outcome, disease progression, overall prognosis or a combination thereof in various cancers and disorders of the immune system.
Evasion of apoptosis is a hallmark of cancer (Hanahan & Weinberg (2000) Cell 100:57-70). Cancer cells must overcome a continual bombardment by cellular stresses such as DNA damage, oncogene activation, aberrant cell cycle progression and harsh microenvironments that would cause normal cells to undergo apoptosis. One of the primary means by which cancer cells evade apoptosis is by up-regulation of anti-apoptotic proteins of the Bcl-2 family.
A particular type of neoplastic disease for which improved therapies are needed is non-Hodgkin's lymphoma (NHL). NHL is the sixth most prevalent type of new cancer in the U.S. and occurs primarily in patients 60-70 years of age. NHL is not a single disease but a family of related diseases, which are classified on the basis of several characteristics including clinical attributes and histology.
One method of classification places different histological subtypes into two major categories based on natural history of the disease, i.e., whether the disease is indolent or aggressive. In general, indolent subtypes grow slowly and are generally incurable, whereas aggressive subtypes grow rapidly and are potentially curable. Follicular lymphomas are the most common indolent subtype, and diffuse large-cell lymphomas constitute the most common aggressive subtype. The oncoprotein Bcl-2 was originally described in non-Hodgkin's B-cell lymphoma.
Treatment of follicular lymphoma typically consists of biologically-based or combination chemotherapy. Combination therapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) is routinely used, as is combination therapy with rituximab, cyclophosphamide, vincristine and prednisone (RCVP). Single-agent therapy with rituximab (targeting CD20, a phosphoprotein uniformly expressed on the surface of B-cells) or fludarabine is also used. Addition of rituximab to chemotherapy regimens can provide improved response rate and increased progression-free survival.
Radioimmunotherapy agents, high-dose chemotherapy and stem cell transplants can be used to treat refractory or relapsed NHL. Currently, there is not an approved treatment regimen that produces a cure, and current guidelines recommend that patients be treated in the context of a clinical trial, even in a first-line setting.
First-line treatment of patients with aggressive large B-cell lymphoma typically consists of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), or dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (DA-EPOCH-R).
Most lymphomas respond initially to any one of these therapies, but tumors typically recur and eventually become refractory. As the number of regimens patients receive increases, the more chemotherapy-resistant the disease becomes. Average response to first-line therapy is approximately 75%, 60% to second-line, 50% to third-line, and about 35-40% to fourth-line therapy. Response rates approaching 20% with a single agent in a multiple relapsed setting are considered positive and warrant further study.
Other neoplastic diseases for which improved therapies are needed include leukemias such as chronic lymphocytic leukemia (like NHL, a B-cell lymphoma) and acute lymphocyctic leukemia.
Chronic lymphoid leukemia (CLL) is the most common type of leukemia. CLL is primarily a disease of adults, more than 75% of people newly diagnosed being over the age of 50, but in rare cases it is also found in children. Combination chemotherapies are the prevalent treatment, for example fludarabine with cyclophosphamide and/or rituximab, or more complex combinations such as CHOP or R-CHOP.
Acute lymphocyctic leukemia, also known as acute lymphoblastic leukemia (ALL), is primarily a childhood disease, once with essentially zero survival but now with up to 75% survival due to combination chemotherapies similar to those mentioned above. New therapies are still needed to provide further improvement in survival rates.
Current chemotherapeutic agents elicit their antitumor response by inducing apoptosis through a variety of mechanisms. However, many tumors ultimately become resistant to these agents. Bcl-2 and Bcl-XL have been shown to confer chemotherapy resistance in short-term survival assays in vitro and, more recently, in vivo. This suggests that if improved therapies aimed at suppressing the function of Bcl-2 and Bcl-XL can be developed, such chemotherapy-resistance could be successfully overcome.
Involvement of Bcl-2 proteins in bladder cancer, brain cancer, breast cancer, bone marrow cancer, cervical cancer, CLL, colorectal cancer, esophageal cancer, hepatocellular cancer, lymphoblastic leukemia, follicular lymphoma, lymphoid malignancies of T-cell or B-cell origin, melanoma, myelogenous leukemia, myeloma, oral cancer, ovarian cancer, non-small cell lung cancer, prostate cancer, small cell lung cancer, spleen cancer and the like is described in International Patent Publication Nos. WO 2005/024636 and WO 2005/049593.
Involvement of Bcl-2 proteins in immune and autoimmune diseases is described, for example, by Puck & Zhu (2003) Current Allergy and Asthma Reports 3:378-384; Shimazaki et al. (2000) British Journal of Haematology 110(3):584-590; Rengan et al. (2000) Blood 95(4):1283-1292; and Holzelova et al. (2004) New England Journal of Medicine 351(14):1409-1418. Involvement of Bcl-2 proteins in bone marrow transplant rejection is disclosed in United States Patent Application Publication No. US 2008/0182845.
Compounds that occupy a binding site on Bcl-2 proteins are known. To be therapeutically useful by oral administration, such compounds desirably have high binding affinity, exhibiting for example Ki<1 nM, preferably <0.1 nM, more preferably <0.01 nM, to proteins of the Bcl-2 family, specifically Bcl-2, Bcl-XL and Bcl-w. It is further desirable that they be formulated in a manner that provides high systemic exposure after oral administration. A typical measure of systemic exposure after oral administration of a compound is the area under the curve (AUC) resulting from graphing plasma concentration of the compound versus time from oral administration.
Where aqueous solubility of Bcl-2 binding compounds is very low, the formulator faces a significant challenge in assuring acceptable oral bioavailability, which is strongly dependent on solubility in the aqueous medium of the gastrointestinal tract. This is true even where binding affinity is very high. The challenge becomes even greater when considering the need to provide an adequate drug loading in the formulation, so that a therapeutically effective dose can be administered in an acceptably small volume of formulated product.
Liquid dosage forms (including encapsulated liquids) can be useful for some drugs of low aqueous solubility, provided a suitable pharmaceutically acceptable solvent system (generally lipid-based) can be found that provides adequate drug loading without posing solubility or storage-stability issues. Other approaches that have been proposed for such drugs include solid dispersions, which bring their own challenges.
For a variety of reasons, such as patient compliance and unpleasant taste, a solid dosage form is often preferred over a liquid dosage form. In most instances, however, oral solid dosage forms of a drug provide lower bioavailability than oral solutions of the drug.
Various solutions to the challenge of low oral bioavailability have been proposed in the art. For example, Sharma & Joshi (2007) Asian Journal of Pharmaceutics 1(1):9-19 discuss various solubility enhancement strategies in preparing solid dispersions. A solvent evaporation method for preparing solid dispersions is described therein, mentioning as an example a solid dispersion of etoricoxib, prepared by a process that includes dissolving polyethylene glycol (PEG), polyvinylpyrrolidone (PVP or povidone) and the active ingredient in 2-propanol.
Apoptosis-inducing drugs that target Bcl-2 family proteins such as Bcl-2 and Bcl-XL are best administered according to a regimen that provides continual, for example daily, replenishment of the plasma concentration, to maintain the concentration in a therapeutically effective range. This can be achieved by daily parenteral, e.g., intravenous (i.v.) or intraperitoneal (i.p.) administration. However, daily parenteral administration is often not practical in a clinical setting, particularly for outpatients. To enhance clinical utility of an apoptosis-inducing agent, for example as a chemotherapeutic in cancer patients, a solid dosage form with acceptable oral bioavailability would be highly desirable. Such a dosage form, and a regimen for oral administration thereof, would represent an important advance in treatment of many types of cancer, including NHL, CLL and ALL, and would more readily enable combination therapies with other chemotherapeutics.
There is now provided a solid dispersion comprising, in essentially non-crystalline, for example amorphous, form, a compound of Formula I:
where:
There is further provided a solid orally deliverable dosage form comprising such a solid dispersion, optionally together with one or more additional excipients.
There is still further provided a process for preparing a solid dispersion as described above. This process comprises:
The compound present in the finished solid dispersion can be in the same chemical form (e.g., parent compound or salt) as in the API used to prepare it. Alternatively, in some embodiments the process can comprise one or more additional steps wherein the API is converted from parent compound to salt or vice versa. According to one such embodiment, the process further comprises, prior to removing the solvent, adding a base for conversion of the API in salt form to its corresponding parent compound, and optionally extracting a by-product of such conversion (e.g., a salt by-product) from the resulting mixture. According to another such embodiment, the process further comprises, prior to removing the solvent, adding an acid for conversion of the API in parent compound form to a salt, for example an acid addition salt.
There is still further provided a solid dispersion prepared by the process described above.
There is still further provided a method for treating a neoplastic, immune or autoimmune disease, comprising orally administering to a subject having the disease a therapeutically effective amount of a solid dispersion as described above, or one or more solid dosage forms comprising such a dispersion. Examples of neoplastic diseases include cancers. A specific illustrative type of cancer that can be treated according to the present method is non-Hodgkin's lymphoma (NHL). Another specific illustrative type of cancer that can be treated according to the present method is chronic lymphocytic leukemia (CLL). Yet another specific illustrative type of cancer that can be treated according to the present method is acute lymphocytic leukemia (ALL), for example in a pediatric patient.
Additional embodiments of the invention, including more particular aspects of those provided above, will be found in, or will be evident from, the detailed description that follows.
Attempts to formulate a compound of Formula I or a salt thereof as an orally deliverable dosage form have been frustrated by the very limited number of pharmaceutically acceptable liquid solvent systems providing acceptable solubility of the compound or salt, and by a tendency with all such solvent systems tested for precipitation of insoluble solids during storage. It has now been found that a more successful approach is to formulate the compound or salt as a solid dispersion. Details of that approach, by which a combination of satisfactory drug loading, acceptable stability and adequate bioavailability are all achievable with a very unpromising class of active ingredient, are disclosed herein.
A solid dispersion in accordance with the present disclosure comprises an active ingredient in an essentially non-crystalline or amorphous form, which is usually more soluble than the crystalline form. The term “solid dispersion” herein encompasses systems having small solid-state particles (e.g., essentially non-crystalline or amorphous particles) of one phase dispersed in another solid-state phase. More particularly, the present solid dispersions comprise particles of one or more active ingredients dispersed in an inert carrier or matrix in solid state, and can be prepared by melting or solvent methods or by a combination of melting and solvent methods. According to the present invention a solvent method as described herein is particularly favored.
An “amorphous form” refers to a particle without definite structure, i.e., lacking crystalline structure.
The term “essentially non-crystalline” herein means that no more than about 5%, for example no more than about 2% or no more than about 1% crystallinity is observed by X-ray diffraction analysis. In a particular embodiment, no detectable crystallinity is observed by one or both of X-ray diffraction analysis or polarization microscopy. In this regard it is to be noted that, when no detectable crsytallinity is observed, the solid dispersion referenced herein may additionally or alternatively be described as a solid solution.
A. Active Compound
Compounds of Formula I, including salts thereof, useful herein typically have very low solubility in water, being classed as essentially insoluble, i.e., having a solubility of less than about 10 μg/ml. Examples of such active ingredients are, for example, Biopharmaceutics Classification System (BCS) Class IV drug substances that are characterized by low solubility and low permeability (see “Waiver of in vivo bioavailability and bioequivalence studies for immediate-release solid oral dosage forms based on a biopharmaceutics classification system”, U.S. Department of Health and Human Services, Food and Drug Administration, Center for Drug Evaluation and Research (CDER), August 2000). It will be recognized that aqueous solubility of many compounds is pH-dependent; in the case of such compounds the solubility of interest herein is at a physiologically relevant pH, for example a pH of about 1 to about 8. Thus, in various embodiments, the drug has a solubility in water, at least at one point in a pH range from about 1 to about 8, of less than about 10 μg/ml, in some cases less than about 1 μg/ml or even less than about 0.1 μg/ml. Illustratively, a particular compound useful herein has a solubility in water at pH 4 of <0.004 μg/ml.
Solid dispersions of the present invention comprise as active ingredient a compound of Formula I as defined above, or a pharmaceutically acceptable salt of such a compound. Optionally they may further comprise a second active ingredient, for example a therapeutic agent useful in combination therapy with the compound of Formula I as indicated hereinbelow.
In one embodiment, the compound has Formula I where R0 is chloro.
In a further embodiment, the compound has Formula I where R1 is methyl or methoxy, R2 is methyl, and R3 and R4 are each H.
In a still further embodiment, the compound has Formula I where R5 is trifluoromethyl, trifluoromethylsulfonyl, chloro, bromo or nitro. In a more particular embodiment, if A2 is —CH— then R5 is nitro; and if A2 is —N— then R5 is bromo.
In a more particular embodiment, the compound has Formula I where (a) R0 is chloro, (b) R1 is methyl or methoxy, R2 is methyl, and R3 and R4 are each H, and (c) R5 is trifluoromethyl, trifluoromethylsulfonyl, chloro, bromo or nitro.

Illustrative examples of such Z1 groups include without limitation methyl, cyanomethyl, methoxy, fluoro, hydroxy, amino and methylsulfonyl.
The Z2 group, if present, is a further 3- to 7-membered carbocyclic or heterocyclic ring, optionally substituted with no more than two Z1 groups as described above. Ring Z2, if present, is typically but not necessarily saturated, and in most cases is not further substituted. In one embodiment Z2 is a saturated carbocyclic ring, for example but not limited to cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. In another embodiment Z2 is a saturated heterocyclic ring, for example but not limited to azetidinyl, oxetanyl, thietanyl, pyrrolidinyl, imazolidinyl, pyrazolidinyl, tetrahydrofuranyl, oxazolidinyl, isoxazolidinyl, thiophanyl, thiazolidinyl, isothiazolidinyl, piperidinyl, piperazinyl, tetrahydropyranyl, 1,4-dioxanyl, morpholinyl or tetrahydrothiopyranyl.

No. 12/787,682 (U.S. 2010/0305122) in Examples 1-378 thereof, and pharmaceutically acceptable salts of such compounds, independently of whether these compounds are individually embraced by the present Formula I. Compounds 1-378 of these Examples, and illustrative procedures for their synthesis, are reproduced hereinbelow. In a further embodiment, the API present in the solid dispersion is selected from Compounds 1-378 and pharmaceutically acceptable salts thereof, but only to the extent that such Examples are individually embraced by the present Formula I. The entire disclosure of U.S. application Ser. No. 12/787,682 (U.S. 2010/0305122) is expressly incorporated herein by reference.

Acid addition salts are those derived from reaction of a compound of Formula I with an acid. For example, salts including the acetate, adipate, alginate, ascorbate, bicarbonate, citrate, aspartate, benzoate, benzenesulfonate (besylate), bisulfate, butyrate, camphorate, camphorsulfonate, digluconate, ethanedisulfonate, formate, fumarate, glycerophosphate, glutamate, hemisulfate, heptanoate, hexanoate, hydrobromide, hydrochloride, hydroiodide, 1-hydroxy-2-naphthoate, lactate, lactobionate, malate, maleate, malonate, mesitylenesulfonate, methanesulfonate, naphthalenesulfonate, nicotinate, oxalate, pamoate, pectinate, persulfate, phosphate, picrate, propionate, succinate, sulfate, tartrate, thiocyanate, trichloroacetate, trifluoroacetate, para-toluenesulfonate and undecanoate salts of a compound of Formula I can be used in a composition of the invention.
Basic addition salts, including those derived from reaction of a compound with the bicarbonate, carbonate, hydroxide or phosphate of cations such as lithium, sodium, potassium, calcium and magnesium, can likewise be used.
A compound of Formula I typically has more than one protonatable nitrogen atom and is consequently capable of forming acid addition salts with more than one, for example about 1.2 to about 2, about 1.5 to about 2 or about 1.8 to about 2, equivalents of acid per equivalent of the compound.
A compound of Formula I typically has more than one protonatable nitrogen atom and is consequently capable of forming acid addition salts with more than one, for example about 1.2 to about 2, about 1.5 to about 2 or about 1.8 to about 2, equivalents of acid per equivalent of the compound.
Without being bound by theory, it is believed that the therapeutic efficacy of compounds of Formula I is due at least in part to their ability to bind to a Bcl-2 family protein such as Bcl-2, Bcl-XL or Bcl-w in a way that inhibits the anti-apoptotic action of the protein, for example by occupying the BH3 binding groove of the protein. It will generally be found desirable to select a compound having high binding affinity for a Bcl-2 family protein, for example a Ki<1 nM, preferably <0.1 nM, more preferably <0.01 nM.
A compound of Formula I or a salt thereof is present in a solid dispersion of the invention in an amount that can be therapeutically effective when the composition is administered to a subject in need thereof according to an appropriate regimen. Dosage amounts are expressed herein as parent-compound-equivalent amounts unless the context requires otherwise. Typically, a unit dose (the amount administered at a single time), which can be administered at an appropriate frequency, e.g., twice daily to once weekly, is about 10 to about 1,000 mg, depending on the compound in question. Where frequency of administration is once daily (q.d.), unit dose and daily dose are the same. Illustratively, the unit dose is typically about 25 to about 1,000 mg, more typically about 50 to about 500 mg, for example about 50, about 100, about 150, about 200, about 250, about 300, about 350, about 400, about 450 or about 500 mg. Where the dosage form comprises a capsule shell enclosing the solid dispersion, or a tablet wherein the solid dispersion is formulated with other ingredients, a unit dose can be deliverable in a single dosage form or a plurality of dosage forms, most typically 1 to about 10 dosage forms.
D. Formulations
The higher the unit dose, the more desirable it becomes to prepare a solid dispersion having a relatively high concentration of the drug therein. Typically, the concentration of drug in the solid dispersion is at least about 1%, e.g., about 1% to about 50%, by parent-compound-equivalent weight, but lower and higher concentrations can be acceptable or achievable in specific cases. Illustratively, the drug concentration in various embodiments is at least about 2%, e.g., about 2% to about 50%, or at least about 5%, e.g., about 5% to about 40%, for example about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35% or about 40%, by parent-compound-equivalent weight. In some embodiments, the drug concentration may be between about 5% and about 15%, such as between about 5% and about 12%, such as about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, or about 12%.
The major component of the matrix of a solid dispersion product is a polymer that is hydrophilic or water-soluble at least in a part of the pH scale, more particularly at a pH occurring in the gastrointestinal (GI) tract, or a combination of such polymers. A polymer or polymer mixture useful herein is solid at ambient temperature and, in the interests of good storage stability at a range of temperatures, should remain solid even at the highest temperatures typically experienced during storage, transport and handling of the product. A useful property of a polymer determining its usefulness herein is therefore its glass transition temperature (Tg). Suitable water-soluble polymers include, but are not limited to, those having a Tg of at least about 40° C., at least about 50° C., at least about 60° C., or more, and more particularly about 80° C. to about 180° C. Methods for determining Tg values of organic polymers are described for example in Sperling, ed. (1992) Introduction To Physical Polymer Science, 2nd edition, John Wiley & Sons, Inc.
Polymers are considered water-soluble if they form a clear homogeneous solution in water (e.g., a solution that is essentially uniform throughout, and that appears clear under visual inspection or alternatively using an instrument such as a turbidimeter, the solution for example exhibiting little or no scattering of a light beam going therethrough). When dissolved at 20° C. in an aqueous solution at 2% (w/v), a suitable water-soluble polymer illustratively has an apparent viscosity of about 1 to about 5000 mPa·s, for example about 1 to about 700 mPa·s, or about 5 to about 100 mPa·s. Water-dispersable or water-swellable polymers can also be used.
Non-limiting examples of polymeric carriers useful herein include:
Suitable povidones include, without limitation, those having a K-value (a measure of viscosity of an aqueous solution of the povidone) of about 12, about 15, about 17, about 25, about 30 or about 90, and mixtures thereof. A particular example of a useful povidone is povidone (or PVP) K30. A particular example of a useful copovidone is one consisting of about 60% N-vinyl pyrrolidone and about 40% vinyl acetate monomers, referred to herein as “copovidone 60/40”.
Another suitable polymer is a mixture of PVP and polyvinyl acetate, such as that sold under the name Kollidon™ SR by BASF AG. In some embodiments, a vinylpyrrolidone-vinyl acetate copolymer commercially available as Kollidon VA 64, which is soluble both in water and in alcohol, is suitable in the formulations of the present invention.
Suitable HPMCs and derivatives thereof include, without limitation, HPMC E3, HPMC E5, HPMC E6, HPMC E15, HPMC K3, HPMC A4, HPMC A15, HPMC-AS LF, HPMC-AS MF, HPMC-AS HF, HPMC-AS LG, HPMC-AS MG, HPMC-AS HG, HPMC-P 50, HPMC-P 55 and mixtures thereof.
Suitable ethylcelluloses include, without limitation, those sold under the Ethocel™ trademark of Dow Chemical Company as Ethocel™ 4, Ethocel™ 7, Ethocel™ 10, Ethocel™ 14 and Ethocel™ 20, products of other manufacturers equivalent thereto, and mixtures thereof.
Suitable methacrylic acid/methyl methacrylate copolymers include, without limitation, those sold under the Eudragit™ trademark of Rohm GmbH as Eudragit™ L100, Eudragit™ L100-55 and Eudragit™ S 100, products of other manufacturers equivalent thereto, and mixtures thereof.
Suitable PEGs include, without limitation, PEG 400, PEG 600, PEG 1450, PEG 3350, PEG 4000, PEG 6000, PEG 8000, PEG 20000 and mixtures thereof. Lower molecular-weight PEGs such as PEG 400 and PEG 600 may be unsuitable as the sole polymeric carrier but can be useful in combination with other polymers.
Suitable poloxamers include, without limitation, poloxamer 124, poloxamer 188, poloxamer 237, poloxamer 338, poloxamer 407 and mixtures thereof. It will be noted that poloxamers have surfactant properties and can be included primarily for these properties as well as their polymeric nature.
In one embodiment, the solid dispersion matrix comprises one or more polymeric carriers selected from the group consisting of povidones, copovidones, HPMCs, polyethylene glycol/polyvinyl caprolactam/polyvinyl acetate graft copolymers and mixtures thereof. In a more particular embodiment, the solid dispersion matrix comprises one or more polymeric carriers selected from the group consisting of povidone K30, copovidone 60/40, HPMC E5, Soluplus™ polyethylene glycol/polyvinyl caprolactam/polyvinyl acetate graft copolymer and products equivalent to Soluplus™
One or more polymeric carriers typically constitute in total about 20% to about 95%, such as about 20% to about 90%, for example about 40% to about 85%, or about 60% to about 85%, or about 70% to about 85%, or even about 75% to about 85%, by weight of the solid dispersion.
Upon oral administration and exposure to GI fluid, it is believed without being bound by theory that, through interplay between the polymeric carrier and a surfactant component of the solid dispersion, a suitable release rate and inhibition of crystallization or recrystallization of the active ingredient are provided, thereby permitting bioabsorption.
The surfactant component can be anionic, non-ionic or can comprise a combination of anionic and non-ionic surfactants. Useful pharmaceutically acceptable anionic surfactants include alkyl sulfates (e.g., sodium lauryl sulfate), alkylcarboxylates, alkylbenzole sulfates and secondary alkane sulfonates.
Particularly useful as surfactants herein are pharmaceutically acceptable non-ionic surfactants, especially those having a hydrophilic-lipophilic balance (HLB) value of about 12 to about 18, for example about 13 to about 17, or about 14 to about 16. The HLB system (see Fiedler (2002) Encyclopedia of Excipients, 5th edition, Aulendorf: ECV-Editio-Cantor-Verlag) assigns numeric values to surfactants, with lipophilic substances receiving lower HLB values and hydrophilic substances receiving higher HLB values.
Non-limiting examples of non-ionic surfactants useful herein include:
EL™ of BASF or equivalent product), PEG-40 hydrogenated castor oil (e.g., Cremophor RH™ 40 or equivalent product) and PEG-60 hydrogenated castor oil (e.g., Cremophor RH™ 60 or equivalent product);
In one embodiment, the solid dispersion comprises one or more surfactants selected from the group consisting of polyoxyethylene glycerides (including polyoxyethylene castor oil derivatives), polysorbates, TPGS and mixtures thereof. In a more particular embodiment, the solid dispersion matrix comprises one or more polymeric carriers selected from the group consisting of PEG-40 hydrogenated castor oil, polysorbate 80, polysorbate 20 and TPGS.
One or more surfactants typically constitute in total about 2% to about 25%, for example about 5% to about 20%, such as between about 5% and about 15%, or between about 5% and about 10%, by weight of the solid dispersion.
Other, optional, components of the solid dispersion include, without limitation, one or more lubricants, glidants or flow regulators. Such a material, for example colloidal silicon dioxide or fumed silica (e.g., Aerosil), can reduce adhesion of the extrudable mixture to the screw and wall of the extruder and can facilitate the smooth passage of extrudate through the die. Illustratively, colloidal silicon dioxide can constitute zero to about 5%, for example about 0.1% to about 2%, by weight of the solid dispersion. The solid dispersion can also optionally contain one or more bulking agents (fillers), disintegrants, cosolvents such as propylene glycol esters of fatty acids (e.g., propylene glycol laurate), plasticizers and/or stabilizers such as antioxidants, light stabilizers, free radical scavengers or antimicrobial agents.
A dosage form of the invention can consist of, or consist essentially of, a solid dispersion as described above. However, in some embodiments a dosage form contains additional excipients and requires additional processing of the solid dispersion. For example, the solid dispersion can be ground to a powder and filled into a capsule shell or molded or compressed to form a tablet, with additional excipients as may be conventionally used in such dosage forms.
Thus orally deliverable solid dosage forms of the invention include but are not limited to capsules, dragees, granules, pills, powders and tablets. Excipients commonly used to formulate such dosage forms include encapsulating materials or formulation additives such as absorption accelerators, antioxidants, binders, buffers, coating agents, coloring agents, diluents, disintegrating agents, emulsifiers, extenders, fillers, flavoring agents, humectants, lubricants, preservatives, propellants, releasing agents, sterilizing agents, sweeteners, solubilizers and mixtures thereof. Many excipients have two or more functions in a pharmaceutical composition. Characterization herein of a particular excipient as having a certain function, e.g., diluent, disintegrant, binding agent, etc., should not be read as limiting to that function. Further information on excipients can be found in standard reference works such as Handbook of Pharmaceutical Excipients, 3rd ed. (Kibbe, ed. (2000), Washington: American Pharmaceutical Association).

Microcrystalline cellulose and silicified microcrystalline cellulose are particularly useful diluents, and are optionally used in combination with a water-soluble diluent such as mannitol. Illustratively, a suitable weight ratio of microcrystalline cellulose or silicified microcrystalline cellulose to mannitol is about 10:1 to about 1:1, but ratios outside this range can be useful in particular circumstances.

Binding agents or adhesives are useful excipients, particularly where the composition is in the form of a tablet. Such binding agents and adhesives should impart sufficient cohesion to the blend being tableted to allow for normal processing operations such as sizing, lubrication, compression and packaging, but still allow the tablet to disintegrate and the composition to be absorbed upon ingestion. Suitable binding agents and adhesives include, either individually or in combination, acacia; tragacanth; glucose; polydextrose; starch including pregelatinized starch; gelatin; modified celluloses including methylcellulose, carmellose sodium, hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose, hydroxyethylcellulose and ethylcellulose; dextrins including maltodextrin; zein; alginic acid and salts of alginic acid, for example sodium alginate; magnesium aluminum silicate; bentonite; polyethylene glycol (PEG); polyethylene oxide; guar gum; polysaccharide acids; polyvinylpyrrolidone (povidone or PVP), for example povidone K-15, K-30 and K-29/32; polyacrylic acids (carbomers); polymethacrylates; and the like.

One or more wetting agents, if present, typically constitute in total about 0.1% to about 15%, for example about 0.2% to about 10%, or about 0.5% to about 7%, by weight of the composition, excluding surfactant present in the solid dispersion.
Nonionic surfactants, more particularly poloxamers, are examples of wetting agents that can be useful herein. Illustratively, a poloxamer such as Pluronic™ F 127, if present, can constitute about 0.1% to about 10%, for example about 0.2% to about 7%, or about 0.5% to about 5%, by weight of the composition, excluding surfactant present in the solid dispersion.
Lubricants reduce friction between a tableting mixture and tableting equipment during compression of tablet formulations. Suitable lubricants include, either individually or in combination, glyceryl behenate; stearic acid and salts thereof, including magnesium, calcium and sodium stearates; hydrogenated vegetable oils; glyceryl palmitostearate; talc; waxes; sodium benzoate; sodium acetate; sodium fumarate; sodium stearyl fumarate; PEGs (e.g., PEG 4000 and PEG 6000); poloxamers; polyvinyl alcohol; sodium oleate; sodium lauryl sulfate; magnesium lauryl sulfate; and the like. One or more lubricants, if present, typically constitute in total about 0.05% to about 10%, for example about 0.1% to about 5%, or about 0.2% to about 2%, by weight of the composition. Sodium stearyl fumarate is a particularly useful lubricant.
Anti-adherents reduce sticking of a tablet formulation to equipment surfaces.

Glidants improve flow properties and reduce static in a tableting mixture. Suitable glidants include, either individually or in combination, colloidal silicon dioxide, starch, powdered cellulose, sodium lauryl sulfate, magnesium trisilicate and metallic stearates. One or more glidants, if present, typically constitute in total about 0.05% to about 10%, for example about 0.1% to about 7%, or about 0.2% to about 5%, by weight of the composition, excluding glidant present in the solid dispersion. Colloidal silicon dioxide is a particularly useful glidant.
Other excipients such as buffering agents, stabilizers, antioxidants, antimicrobials, colorants, flavors and sweeteners are known in the pharmaceutical art and can be used in compositions of the present invention. Tablets can be uncoated or can comprise a core that is coated, for example with a nonfunctional film or a release-modifying or enteric coating. Capsules can have hard or soft shells comprising, for example, gelatin (in the form of hard gelatin capsules or soft elastic gelatin capsules), starch, carrageenan and/or HPMC, optionally together with one or more plasticizers.
E. Method of Preparation
A solvent process for preparing a solid dispersion as described above comprises dissolving the API, the polymeric carrier and the surfactant in a suitable solvent; and removing the solvent to provide the solid dispersion. Optionally, where the API is in free base (parent-compound) form and it is desired to provide a solid dispersion of the drug at least partly in the form of an acid addition salt, an acid is added before solvent removal to effect conversion of the API to the corresponding salt. For example, one or more acids selected from the group consisting of acetic, adipic, alginic, ascorbic, carbonic, citric, aspartic, benzoic, benzenesulfonic, sulfuric, butyric, camphoric, camphorsulfonic, gluconic, ethanedisulfonic, formic, fumaric, glycerophosphoric, glutamic, heptanoic, hexanoic, hydrobromic, hydrochloric, hydroiodic, 1-hydroxy-2-naphthoic, lactic, lactobionic, malic, maleic, malonic, mesitylenesulfonic, methanesulfonic, naphthalenesulfonic, nicotinic, oxalic, pamoic, pectinic, phosphoric, picric, propionic, succinic, sulfuric, tartaric, thiocyanic, trichloroacetic, trifluoroacetic, para-toluenesulfonic and undecanoic acids can be added before solvent removal, resulting in at least partial formation of the corresponding acid addition salt of the API. Such one or more acids can be added in any suitable amount, for example from 0 to about 10 molar equivalents per molar equivalent of the compound of Formula I.
Alternatively, where the API is in salt form and it is desired to provide a solid dispersion of the drug in free base (parent-compound) form, a base is added before solvent removal to effect conversion of the API to its corresponding free base. The salt by-product of such conversion can remain in the product or is optionally extracted before solvent removal.
In the dissolving step, the various components can be added in any order. For example, each ingredient can be added to the solvent separately and then dissolved therein. Alternatively, the polymeric carrier and/or surfactant can be pre-mixed with the API, and the resulting mixture then added to the solvent. In some embodiments, the polymeric carrier and the API may be dissolved in the solvent prior to adding the surfactant. The polymeric carrier and the API may be pre-mixed prior to addition of the solvent.
In principle any solvent can be used so long as it is effective to dissolve the active ingredient, polymer carrier and surfactant. Non-limiting examples of solvents that can be useful include methanol, ethanol, acetone, tetrahydrofuran (THF), dichloromethane and mixtures thereof. Optionally a cosolvent can be included. Dual solvent systems that have been found particularly useful include dichloromethane/methanol, for example 95 parts dichloromethane to 5 parts methanol, and THF/water, for example 90 parts THF to 10 parts water.
Solvent removal can be accomplished using heat, vacuum or a combination thereof. In some embodiments, heating at a temperature between about 40° C. to about 90° C., such as about 50° C. to about 80° C., for example about 55° C. to about 75° C., may be found suitable. In some embodiments, solvent removal may be accomplished using a combination of heat and vacuum. In some embodiments, the solvent may be removed by heating at a temperature between about 40° C. to about 90° C., such as about 50° C. to about 80° C., for example about 55° C. to about 75° C. while simultaneously subjecting the composition to a vacuum. A vacuum gradient may be used. For example, the vacuum may be increased during solvent evaporation in, e.g., a rotary evaporator, starting conveniently at ambient pressure and slowly increasing the vacuum over an extended duration. In some embodiments, the pressure may be decreased from ambient pressure to about 100 mm Hg over a period sufficient to evaporate the solvent, which may be, for example, between about 1 hour and about 5 hours. In some preferred embodiments, the pressure may be decreased from ambient pressure to about 200 mm Hg over a period sufficient to evaporate the solvent, which may be, for example, between about 1 hour and about 5 hours, such as between about 1 hours and about 3 hours. The duration necessary to adequately remove solvent is, in part, dependent upon the volatility of the solvent in which volatile solvents, e.g., methanol, may be removed more quickly. After solvent removal, the resulting product is cooled (if necessary) to ambient temperature. Illustrative methods of solvent removal include without limitation rotary evaporation and spray-drying.
In some embodiments, the composition may be subjected to an additional solvent evaporation method, for example, oven drying at a temperature exceeding about 40° C., such as between about 50° C. and about 80° C. for a duration sufficient to provide a solid dispersion.
Solvent evaporation according to the present invention yields a pharmaceutical composition in which the active pharmaceutical ingredient is “essentially non-crystalline,” meaning that no more than about 5%, for example no more than about 2% or no more than about 1% crystallinity is observed by X-ray diffraction analysis. In a particular embodiment, no detectable crystallinity is observed by one or both of X-ray diffraction analysis or polarization microscopy.
F. Dosage Forms and Regimen
The terms “orally deliverable”, “oral administration” and “orally administered” herein refer to administration to a subject per os (p.o.), that is, administration wherein the composition is immediately swallowed, for example with the aid of a suitable volume of water or other potable liquid. “Oral administration” is distinguished herein from intraoral administration, e.g., sublingual or buccal administration or topical administration to intraoral tissues such as periodontal tissues, that does not involve immediate swallowing of the composition.
The active ingredient form (e.g., parent compound or salt), the polymeric carrier(s), surfactant(s) and other optional ingredients should be selected, and relative amounts of these components should be used, to provide a solid dispersion or dosage form having acceptable bioabsorption when administered orally. Such bioabsorption can be evidenced, for example, by the pharmacokinetic (PK) profile of the solid dispersion or dosage form, more particularly by the Cmax or AUC, for example AUC0-24 or AUC0 at a particular dose or over a range of doses. Illustratively, bioavailability can be expressed as a percentage, for example using the parameter F, which computes AUC for oral delivery of a test composition as a percentage of AUC for intravenous (i.v.) delivery of the drug in a suitable solvent, taking into account any difference between oral and i.v. doses.
Bioavailability can be determined by PK studies in humans or in any suitable model species. For present purposes, a dog model is generally suitable. In various illustrative embodiments, compositions of the invention exhibit oral bioavailability of at least about 15%, at least about 20%, at least about 25% or at least about 30%, up to or exceeding about 50%, in a dog model, when administered as a single dose of about 2.5 to about 10 mg/kg to fasting or non-fasting animals.
Compositions embraced herein, including compositions described generally or with specificity herein, are useful for orally delivering a drug that is a compound of Formula I or a pharmaceutically acceptable salt thereof to a subject. Accordingly, a method of the invention for delivering such a drug to a subject comprises orally administering a composition as described above.
The subject can be human or non-human (e.g., a farm, zoo, work or companion animal, or a laboratory animal used as a model) but in an important embodiment the subject is a human patient in need of the drug, for example to treat a disease characterized by apoptotic dysfunction and/or overexpression of an anti-apoptotic Bcl-2 family protein. A human subject can be male or female and of any age. The patient is typically an adult, but a method of the invention can be useful to treat a childhood cancer such as leukemia, for example acute lymphocytic leukemia, in a pediatric patient.
The composition is normally administered in an amount providing a therapeutically effective daily dose of the drug. The term “daily dose” herein means the amount of drug administered per day, regardless of the frequency of administration. For example, if the subject receives a unit dose of 150 mg twice daily, the daily dose is 300 mg. Use of the term “daily dose” will be understood not to imply that the specified dosage amount is necessarily administered once daily. However, in a particular embodiment the dosing frequency is once daily (q.d.), and the daily dose and unit dose are in this embodiment the same thing.
What constitutes a therapeutically effective dose depends on the particular compound, the subject (including species and body weight of the subject), the disease (e.g., the particular type of cancer) to be treated, the stage and/or severity of the disease, the individual subject's tolerance of the compound, whether the compound is administered in monotherapy or in combination with one or more other drugs, e.g., other chemotherapeutics for treatment of cancer, and other factors. Thus the daily dose can vary within wide margins, for example from about 10 to about 1,000 mg. Greater or lesser daily doses can be appropriate in specific situations. It will be understood that recitation herein of a “therapeutically effective” dose herein does not necessarily require that the drug be therapeutically effective if only a single such dose is administered; typically therapeutic efficacy depends on the composition being administered repeatedly according to a regimen involving appropriate frequency and duration of administration. It is strongly preferred that, while the daily dose selected is sufficient to provide benefit in terms of treating the cancer, it should not be sufficient to provoke an adverse side-effect to an unacceptable or intolerable degree. A suitable therapeutically effective dose can be selected by the physician of ordinary skill without undue experimentation based on the disclosure herein and on art cited herein, taking into account factors such as those mentioned above. The physician may, for example, start a cancer patient on a course of therapy with a relatively low daily dose and titrate the dose upwards over a period of days or weeks, to reduce risk of adverse side-effects.
Illustratively, suitable doses of a compound of Formula I are generally about 25 to about 1,000 mg/day, more typically about 50 to about 500 mg/day or about 200 to about 400 mg/day, for example about 50, about 100, about 150, about 200, about 250, about 300, about 350, about 400, about 450 or about 500 mg/day, administered at an average dosage interval of about 3 hours to about 7 days, for example about 8 hours to about 3 days, or about 12 hours to about 2 days. In most cases a once-daily (q.d.) administration regimen is suitable.
An “average dosage interval” herein is defined as a span of time, for example one day or one week, divided by the number of unit doses administered over that span of time. For example, where a drug is administered three times a day, around 8 am, around noon and around 6 pm, the average dosage interval is 8 hours (a 24-hour time span divided by 3). If the drug is formulated as a discrete dosage form such as a tablet or capsule, a plurality (e.g., 2 to about 10) of dosage forms administered at one time is considered a unit dose for the purpose of defining the average dosage interval.
Where the composition is in the form of a capsule, one to a small plurality of capsules can be swallowed whole, typically with the aid of water or other imbibable liquid to help the swallowing process. Suitable capsule shell materials include, without limitation, gelatin (in the form of hard gelatin capsules or soft elastic gelatin capsules), starch, carrageenan and HPMC.
Administration can be with or without food, i.e., in a non-fasting or fasting condition. It is generally preferred to administer the present compositions to a non-fasting patient.
G. Monotherapies and Combination Therapies
Compositions of the invention are suitable for use in monotherapy or in combination therapy, for example with other chemotherapeutics or with ionizing radiation. A particular advantage of the present invention is that it permits once-daily oral administration, a regimen which is convenient for the patient who is undergoing treatment with other orally administered drugs on a once-daily regimen. Oral administration is easily accomplished by the patient him/herself or by a caregiver in the patient's home; it is also a convenient route of administration for patients in a hospital or residential care setting.
Combination therapies illustratively include administration of a composition of the present invention concomitantly with one or more of bortezomib, carboplatin, cisplatin, cyclophosphamide, dacarbazine, dexamethasone, docetaxel, doxorubicin, etoposide, fludarabine, irinotecan, paclitaxel, rapamycin, rituximab, vincristine and the like, for example with a polytherapy such as CHOP (cyclophosphamide+doxorubicin+vincristine+prednisone), RCVP (rituximab+cyclophosphamide+vincristine+prednisone), R-CHOP (rituximab+CHOP) or DA-EPOCH-R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab).
A composition of the invention can be administered in combination therapy with one or more therapeutic agents that include, but are not limited to, alkylating agents, angiogenesis inhibitors, antibodies, antimetabolites, antimitotics, antiproliferatives, antivirals, aurora kinase inhibitors, other apoptosis inducing agents (for example, Bcl-xL, Bcl-w and Bfl-1 inhibitors), activators of a death receptor pathway, Bcr-Abl kinase inhibitors, BiTE (bi-specific T-cell engager) antibodies, antibody-drug conjugates, biological response modifiers, cyclin-dependent kinase (CDK) inhibitors, cell cycle inhibitors, cyclooxygenase-2 (COX-2) inhibitors, dual variable domain binding proteins (DVDs), human epidermal growth factor receptor 2 (ErbB2 or HER/2neu) receptor inhibitors, growth factor inhibitors, heat shock protein (HSP)-90 inhibitors, histone deacetylase (HDAC) inhibitors, hormonal therapies, immunologicals, inhibitors of apoptosis proteins (IAPB), intercalating antibiotics, kinase inhibitors, kinesin inhibitors, JAK2 inhibitors, mammalian target of rapamycin (mTOR) inhibitors, microRNAs, mitogen-activated extracellular signal-regulated kinase (MEK) inhibitors, multivalent binding proteins, non-steroidal anti-inflammatory drugs (NSAIDs), poly-ADP (adenosine diphosphate)-ribose polymerase (PARP) inhibitors, platinum chemotherapeutics, polo-like kinase (Pik) inhibitors, phosphoinositide-3 kinase (PI3K) inhibitors, proteasome inhibitors, purine analogs, pyrimidine analogs, receptor tyrosine kinase inhibitors, retinoids, deltoids, plant alkaloids, small inhibitory ribonucleic acids (siRNAs), topoisomerase inhibitors, ubiquitin ligase inhibitors, and the like.
BiTE antibodies are bi-specific antibodies that direct T-cells to attack cancer cells by simultaneously binding the two cells. The T-cell then attacks the target cancer cell. Examples of BiTE antibodies include, but are not limited to, adecatumumab (Micromet MT201), blinatumomab (Micromet MT103) and the like. Without being limited by theory, one of the mechanisms by which T-cells elicit apoptosis of the target cancer cell is by exocytosis of cytolytic granule components, which include perforin and granzyme B. In this regard, Bcl-2 has been shown to attenuate the induction of apoptosis by both perforin and granzyme B. These data suggest that inhibition of Bcl-2 could enhance the cytotoxic effects elicited by T-cells when targeted to cancer cells (Sutton et al. (1997) J. Immunol. 158:5783-5790).
siRNAs are molecules having endogenous RNA bases or chemically modified nucleotides. The modifications do not abolish cellular activity, but rather impart increased stability and/or increased cellular potency. Examples of chemical modifications include phosphorothioate groups, 2′-deoxynucleotide, 2′-OCH3-containing ribonucleotides, 2′-F-ribonucleotides, 2′-methoxyethyl ribonucleotides, combinations thereof and the like. The siRNA can have varying lengths (e.g., 10-200 bps) and structures (e.g., hairpins, single/double strands, bulges, nicks/gaps, mismatches) and are processed in cells to provide active gene silencing. A double-stranded siRNA (dsRNA) can have the same number of nucleotides on each strand (blunt ends) or asymmetric ends (overhangs). The overhang of 1-2 nucleotides can be present on the sense and/or the antisense strand, as well as present on the 5′- and/or the 3′-ends of a given strand. For example, siRNAs targeting Mc1-1 have been shown to enhance the activity of ABT-263 or ABT-737 in various tumor cell lines (Tse et al. (2008) Cancer Res. 68:3421-3428 and references therein).
Multivalent binding proteins are binding proteins comprising two or more antigen binding sites. Multivalent binding proteins are engineered to have the three or more antigen binding sites and are generally not naturally occurring antibodies. The term “multispecific binding protein” means a binding protein capable of binding two or more related or unrelated targets. Dual variable domain (DVD) binding proteins are tetravalent or multivalent binding proteins binding proteins comprising two or more antigen binding sites. Such DVDs may be monospecific (i.e., capable of binding one antigen) or multispecific (i.e., capable of binding two or more antigens). DVD binding proteins comprising two heavy-chain DVD polypeptides and two light-chain DVD polypeptides are referred to as DVD Ig's. Each half of a DVD Ig comprises a heavy-chain DVD polypeptide, a light-chain DVD polypeptide, and two antigen binding sites. Each binding site comprises a heavy-chain variable domain and a light-chain variable domain with a total of 6 CDRs involved in antigen binding per antigen binding site.

In particular embodiments, a composition of the invention is administered in a therapeutically effective amount to a subject in need thereof in combination therapy with etoposide, vincristine, CHOP, rituximab, rapamycin, R-CHOP, RCVP, DA-EPOCH-Ror bortezomib in a therapeutically effective amount, for treatment of a lymphoid malignancy such as B-cell lymphoma or non-Hodgkin's lymphoma.
In other particular embodiments, a composition of the invention is administered in a therapeutically effective amount to a subject in need thereof in monotherapy or in combination therapy with etoposide, vincristine, CHOP, rituximab, rapamycin, R-CHOP, RCVP, DA-EPOCH-R or bortezomib in a therapeutically effective amount, for treatment of chronic lymphocytic leukemia or acute lymphocytic leukemia.
The present invention also provides a method for maintaining in bloodstream of a human cancer patient a therapeutically effective plasma concentration of a compound of Formula I and/or one or more metabolites thereof, comprising administering to the subject a solid dispersion of the compound or a pharmaceutically acceptable salt thereof in essentially non-crystalline form in a matrix that comprises a pharmaceutically acceptable water-soluble polymeric carrier and a pharmaceutically acceptable surfactant, in a parent-compound-equivalent dosage amount of about 50 to about 500 mg per day, at an average dosage interval of about 3 hours to about 7 days.
What constitutes a therapeutically effective plasma concentration depends inter alia on the particular compound of Formula I, the particular cancer present in the patient, the stage, severity and aggressiveness of the cancer, and the outcome sought (e.g., stabilization, reduction in tumor growth, tumor shrinkage, reduced risk of metastasis, etc.). It is strongly preferred that, while the plasma concentration is sufficient to provide benefit in terms of treating the cancer, it should not be sufficient to provoke an adverse side-effect to an unacceptable or intolerable degree.

The following examples are merely illustrative, and do not limit this disclosure in any way. For example, it will be appreciated that lab-scale compositions or formulations, or solid dispersions, referenced herein may in general be scaled up in view of the details provided without departing from the intended scope of the present application.
Trademarked ingredients used in the examples, which can be substituted with comparable ingredients from other suppliers, include:
In the examples, “API” (active pharmaceutical ingredient) can be any compound of Formula I, added in essentially anhydrous parent-compound (i.e., not salt) form. In solid dispersions to which citric acid is added during preparation, the presence of citrate salt of the API is possible but has not been conclusively determined. The following compounds are more specifically contemplated for formulation according to the examples:
A solid dispersion comprising API, TPGS surfactant and Soluplus™ polymer in a weight ratio of approximately 21:5:74 is prepared as follows.
The following solid components are combined in a 100 ml amber glass scintillation vial: 1.0 g API and 3.5 g Soluplus™ polymer. Approximately 45.5 g solvent mixture (THF/water, 90:10) is added to the solids with agitation until the solids are dissolved (this takes approximately 15 minutes), forming a drug/polymer solution. TPGS surfactant (0.05 g) is weighed into a separate 20 ml amber glass scintillation vial, and an aliquot of 10 g of the drug/polymer solution is added to the surfactant, with mixing. The resulting solution is placed in a Genevac rotary evaporator for solvent removal at 80° C. by slowly increasing applied vacuum from ambient to approximately 200 mm Hg over a period of about 3 hours. The powder that remains after solvent removal is collected, with scraping as necessary, from the bottom of the vial, and is screened through a #50-mesh sieve. The sieved powder is then incubated at 50° C. for 30 minutes as a secondary drying step, to provide the solid dispersion.
