Description

CONTROLLED-RELEASE FORMULATION

Field of the Invention The present invention relates to controlled-release dosage formulations that are useful for treating a wide variety of diseases or disorders associated with hepatitis C virus by inhibiting HCV protease (for example HCV NS3/NS4a serine protease), and/or diseases or disorders associated with cathepsin activity and inhibiting cathepsin activity.

BACKGROUND OF THE INVENTION
HCV has been implicated in cirrhosis of the liver and in induction of hepatocellular carcinoma. The prognosis for patients suffering from HCV
infection is currently poor. HCV infection is more difficult to treat than other forms of hepatitis due to the lack of immunity or remission associated with HCV infection.
Current data indicates a less than 50% survival rate at four years post cirrhosis diagnosis.
Patients diagnosed with localized resectable hepatocellular carcinoma have a five-year survival rate of 10-30%, whereas those with localized unresectable hepatocellular carcinoma have a five-year survival rate of less than 1%.
Current therapies for hepatitis C include interferon-a (INF(,,) and combination therapy with ribavirin and interferon. See, e.g.. Beremguer et al. (1998) Proc. Assoc.
Am. Physicians 110(2):98-112. These therapies suffer from a low sustained response rate and frequent side effects. See, e.g., Hoofnagle et al. (1997) N.
Engl.
J. Med. 336:347. Currently, no vaccine is available for HCV infection.
Hepatitis C virus (HCV) is a (+)-sense single-stranded RNA virus that has been implicated as the major causative agent in non-A, non-B hepatitis (NANBH), particularly in blood-associated NANBH (BB-NANBH)(see, International Patent Application Publication No. WO 89/04669 and European Patent Application Publication No. EP 381 216). NANBH is to be distinguished from other types of viral-induced liver disease, such as hepatitis A virus (HAV), hepatitis B virus (HBV), delta hepatitis virus (HDV), cytomegalovirus (CMV) and Epstein-Barr virus (EBV), as well as from other forms of liver disease such as alcoholism and primary biliar cirrhosis.

Recently, an HCV protease necessary for polypeptide processing and viral replication has been identified, cloned and expressed; (see, e.g., U.S. Patent No.
5,712,145). This approximately 3000 amino acid polyprotein contains, from the amino terminus to the carboxy terminus, a nucleocapsid protein (C), envelope proteins (El and E2) and several non-structural proteins (NS1, 2, 3, 4a, 5a and 5b).
NS3 is an approximately 68 kda protein, encoded by approximately 1893 nucleotides of the HCV genome, and has two distinct domains: (a) a serine protease domain consisting of approximately 200 of the N-terminal amino acids; and (b) an RNA-dependent ATPase domain at the C-terminus of the protein. The NS3 protease is considered a member of the chymotrypsin family because of similarities in protein sequence, overall three-dimensional structure and mechanism of catalysis.
Other chymotrypsin-like enzymes are elastase, factor Xa, thrombin, trypsin, plasmin, urokinase, tPA and PSA. The HCV NS3 serine protease is responsible for proteolysis of the polypeptide (polyprotein) at the NS3/NS4a, NS4a/NS4b, NS4b/NS5a and NS5a/NS5b junctions and is thus responsible for generating four viral proteins during viral replication. This has made the HCV NS3 serine protease an attractive target for antiviral chemotherapy.
It has been determined that the NS4a protein, an approximately 6 kda polypeptide, is a co-factor for the serine protease activity of NS3.
Autocleavage of the NS3/NS4a junction by the NS3/NS4a serine protease occurs intramolecularly (i.e., cis) while the other cleavage sites are processed intermolecularly (i.e., trans).
Analysis of the natural cleavage sites for HCV protease revealed the presence of cysteine at P1 and serine at P1' and that these residues are strictly conserved in the NS4a/NS4b, NS4b/NS5a and NS5a/NS5b junctions. The NS3/NS4a junction contains a threonine at P1 and a serine at P1'. The Cys->Thr substitution at NS3/NS4a is postulated to account for the requirement of cis rather than trans processing at this junction. See, e ., Pizzi et al. (1994) Proc.
Natl. Acad.
Sci (USA) 91:888-892, Failla et al. (1996) Folding & Design 1:35-42. The NS3/NS4a cleavage site is also more tolerant of mutagenesis than the other sites.
See, e_gõ Kollykhalov et al. (1994) J. Virol. 68:7525-7533. It has also been found that acidic residues in the region upstream of the cleavage site are required for efficient cleavage. See; e.g.. Komoda et al. (1994) J. Virol. 68:7351-7357.

Inhibitors of HCV protease that have been reported include antioxidants (see, International Patent Application Publication No. WO 98/14181), certain peptides and peptide analogs (see, International Patent Application Publication No. WO
98/17679, Landro et al. (1997) Biochem. 36:9340-9348, Ingallinella et al. (1998) Biochem.
37:8906-8914, Llinas-Brunet et al. (1998) Bioorg. Med. Chem. Lett. 8:1713-1718), inhibitors based on the 70-amino acid polypeptide eglin c (Martin et al.

Hepat. 27:42-28). A ribozyme designed to selectively destroy hepatitis C virus RNA has recently been disclosed (see, BioWorld Today 9 217 : 4 (November 10, 1998)).

There is a need for new treatments and therapies for HCV infection to treat, prevent or ameliorate of one or more symptoms of hepatitis C, methods for modulating the activity of serine proteases, particularly the HCV NS3/NS4a serine protease, and methods of modulating the processing of the HCV polypeptide using the compounds provided herein.
Another aspect of the present invention is directed to inhibiting cathepsin activity. Cathepsins (Cats) belong to the papain superfamily of lysosomal cysteine proteases. Cathepsins are involved in the normal proteolysis and turnover of target proteins and tissues as well as in initiating proteolytic cascades by proenzyme activation and in participating in MHC class II molecule expression. Baldwin (1993) Proc. Natl. Acad. Sci., 90: 6796-6800; Mixuochi (1994) Immunol. Left., 43:189-193.
However, aberrant cathepsin expression has also been implicated in several serious human disease states. Cathepsins have been shown to be abundantly expressed in cancer cells, including breast, lung, prostate, glioblastoma and head/neck cancer cells, (Kos et al. (1998) Oncol. Rep., 5:1349-1361; Yan et al.
(1998) Biol. Chem., 379:113-123; Mort et al. (1997) Int. J Biochem. Cell Biol., 29:
715-720; Friedrick et al. (1999) Eur. J Cancer, 35:138-144) and are associated with poor treatment outcome of patients with breast cancer, lung cancer, brain tumor and head/neck cancer. Kos et al, supra. Additionally, aberrant expression of cathepsin is evident in several inflammatory disease states, including rheumatoid arthritis and osteoarthritis. Keyszer (1995) Arthritis Rheum., 38:976-984.
The molecular mechanisms of cathepsin activity are not completely understood. Recently, it was shown that forced expression of cathepsin B
rescued cells from serum deprivation-induced apoptotic death (Shibata et al. (1998) Biochem.
Biophys. Res. Commun., 251: 199-203) and that treatment of cells with antisense oligonucleotides of cathepsin B induced apoptosis. Isahara et at. (1999) Neuroscience, 91:233-249. These reports suggest an anti-apoptotic role for the cathepsins that is contrary to earlier reports that cathepsins are mediators of apoptosis. Roberts et al (1997) Gastroenterology, 113: 1714-1726; Jones et al.
(1998) Am. J Physiol., 275: G723-730.
Cathepsin K is a member of the family of enzymes which are part of the papain superfamily of cysteine proteases. Cathepsins B, H, L, N and S have been described in the literature. Recently, cathepsin K polypeptide and the cDNA
encoding such polypeptide were disclosed in U.S. Pat. No. 5, 501,969 (called cathepsin 0 therein). Cathepsin K has been recently expressed, purified, and characterized. Bossard, M. J., et al., (1996) J Biol. Chem . 271, 12517-12524;
Drake, F. H., et al., (1996) J. Biol. Chem. 271, 12511-12516; Bromme, D., et al., (1996) J.
Biol. Chem. 271, 2126-2132.
Cathepsin K has been variously denoted as cathepsin 0, cathepsin X or cathepsin 02 in the literature. The designation cathepsin K is considered to be the more appropriate one (name assigned by Nomenclature Committee of the International Union of Biochemistry and Molecular Biology).
Cathepsins of the papain superfamily of cysteine proteases function in the normal physiological process of protein degradation in animals, including humans, e.g., in the degradation of connective tissue. However, elevated levels of these enzymes in the body can result in pathological conditions leading to disease.
Thus, cathepsins have been implicated in various disease states, including but not limited to, infections by pneumocystis carinii, trypsanoma cruzi, trypsanoma brucei brucei, and Crithidia fusiculata; as well as in schistosomiasis malaria, tumor metastasis, metachromatic leukodystrophy, muscular dystrophy, amytrophy, and the like. See International Publication Number WO 94/04172, published on Mar. 3, 1994, and references cited therein. See also European Patent Application EP 0 603 873 Al, and references cited therein. Two bacterial cysteine proteases from P.
gingivallis , called gingipains, have been implicated in the pathogenesis of gingivitis.
Potempa, J., et al. (1994) Perspectives in Drug Discovery and Design , 2, 445-458.
Cathepsin K is believed to play a causative role in diseases of excessive bone or cartilage loss. Bone is composed of a protein matrix in which spindle- or plate-shaped crystals of hydroxyapatite are incorporated. Type I Collagen represents the major structural protein of bone comprising approximately 90% of the structural protein. The remaining 10% of matrix is composed of a number of non-collagenous proteins, including osteocalcin, proteoglycans, osteopontin, osteonectin, thrombospondin, fibronectin, and bone sialoprotein. Skeletal bone undergoes remodeling at discrete foci throughout life. These foci, or remodeling units, undergo a cycle consisting of a bone resorption phase followed by a phase of bone replacement. Bone resorption is carried out by osteoclasts, which are multinuclear cells of hematopoietic lineage. In several disease states, such as osteoporosis and Paget's disease, the normal balance between bone resorption and formation is disrupted, and there is a net loss of bone at each cycle. Ultimately, this leads to weakening of the bone and may result in increased fracture risk with minimal trauma.
The abundant selective expression of cathepsin K in osteoclasts strongly suggests that this enzyme is essential for bone resorption. Thus, selective inhibition of cathepsin K may provide an effective treatment for diseases of excessive bone loss, including, but not limited to, osteoporosis, gingival diseases such as gingivitis and periodontitis, Paget's disease, hypercalcemia of malignancy, and metabolic bone disease. Cathepsin K levels have also been demonstrated to be elevated in chondroclasts of osteoarthritic synovium. Thus, selective inhibition of cathepsin K
may also be useful for treating diseases of excessive cartilage or matrix degradation, including, but not limited to, osteoarthritis and rheumatoid arthritis.
Metastatic neoplastic cells also typically express high levels of proteolytic enzymes that degrade the surrounding matrix. Thus, selective inhibition of cathepsin K may also be useful for treating certain neoplastic diseases.
There are reports in the literature of the expression of Cathepsin B and L
antigen and that activity is associated with early colorectal cancer progression. Troy et al., (2004) Eur J Cancer, 40(10):1610-6. The findings suggest that cysteine proteases play an important role in colorectal cancer progression.
Cathepsin L has been shown to be an important protein mediating the malignancy of gliomas and it has been suggested that its inhibition may diminish their invasion and lead to increased tumor cell apoptosis by reducing apoptotic threshold. Levicar et al., (2003) Cancer Gene Ther., 10(2): 141-51.
Katunama et al., (2002) Arch Biochem Biophys., 397(2):305-11 reports on antihypercalcemic and antimetastatic effects of CLIK-148 in vivo, which is a specific inhibitor of cathepsin L. This reference also reports that CLIK-148 treatment reduced distant bone metastasis to the femur and tibia of melanoma A375 tumors implanted into the left ventricle of the heart.
Rousselet et al., (2004) Cancer Res., 64(1): 146-51 reports that anti-cathepsin L single chain variable fragment (ScFv) could be used to inhibit the tumorigenic and metastatic phenotype of human melanoma, depending on procathepsin L secretion, and the possible use of anti-cathepsin L ScFv as a molecular tool in a therapeutic cellular approach.
Colella et al., (2003) Biotech Histochem., 78(2):101-8 reports that the cysteine proteinases cathepsin L and B participate in the invasive ability of the PC3 prostrate cancer cell line, and the potential of using cystein protease inhibitiors such as cystatins as anti-metastatic agents.

Krueger et al., (2001) Cancer Gene Ther., 8(7):522-8 reports that in human osteosarcoma cell line MNNG/HOS, cathepsin L influences, cellular malignancy by promoting migration and basement membrane degradation..
Frohlich et al., (2204) Arch Dermatol Res., 295(10):411-21 reports that cathepsins B and L are involved in invasion of basal cell carcinoma (BCC) cells.
U.S. Provisional Patent Application Serial No. Not Yet Assigned, entitled "Compounds for Inhibiting Cathepsin Activity", filed April 20, 2005, discloses various types of peptides and/or other compounds as inhibitors of cathepsin.
Cathepsins therefore are attractive targets for the discovery of novel chemotherapeutics and methods of treatment effective against a variety of diseases.
There is a need for compounds useful in the inhibition of cathepsin activity and in the treatment of these disorders.
Further, there is a need for controlled-release dosage formulations to maintain a minimum plasma concentration of such compounds to enhance treatment efficacy.

BRIEF DESCRIPTION OF THE DRAWINGS
The invention is further illustrated by the following drawings in which:
Fig. 1 is a graph of mean viral load measured over time with administration of various doses and regimens of a compound of Formula Ia; and Fig. 2 is a box plot showing serum levels of a compound of Formula Ia measured on day 14 at various times when a compound of Formula Ia is administered twice per day (bid, left box) and when a compound of Formula Ia is administered three times per day (tid, right box).
DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to controlled-release dosage formulations and methods of treatment using the same. The formulations comprise at least one (one or more) compounds of Formulae I to XXVI as discussed above and a controlled-release carrier. One of ordinary skill in the medicinal art will readily appreciate the potential advantages of controlled-release dosage formulations, namely, enhanced delivery to the required site, delivery at the required rate, fewer administrations that increases patient compliance, reduced dangers of overdose or side effects; and also economic advantages by virtue of more efficient dosage, at the expense of possibly more complicated fabrication.
Suitable compounds of formula I are disclosed in PCT International publication W003/062265 published July 31, 2003. Non-limiting examples of certain compounds disclosed in this publication include:

Compounds of formula (XXVI) have been disclosed in U.S. Patent No.
6,143,715 at col. 3, line 6 through col. 62, line 20, incorporated herein by reference.
Isomers of the various compounds of the present invention (where they exist), including enantiomers, stereoisomers, rotamers, tautomers and racemates are also contemplated as being part of this invention. The invention includes d and I
isomers in both pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional techniques, either by reacting optically pure or optically enriched starting materials or by separating isomers of a compound of the present invention. Isomers may also include geometric isomers, e.g., when a double bond is present. Polymorphous forms of the compounds of the present invention, whether crystalline or amorphous, also are contemplated as being part of this invention. The (+) isomers of the present compounds are preferred compounds of the present invention.
Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are also within the scope of this invention.

It will be apparent to one skilled in the art that certain compounds of this invention may exist in alternative tautomeric forms. All such tautomeric forms of the present compounds are within the scope of the invention. Unless otherwise indicated, the representation of either tautomer is meant to include the other. For example, both isomers (1) and (2) are contemplated:
OH

N ~~ (1) I I

(2) wherein R' is H or Cl_6 unsubstituted alkyl.
Prodrugs and solvates of the compounds of the invention are also contemplated herein. A discussion of prodrugs is provided in T. Higuchi and V.
Stella, Pro-drugs as Novel Delivery Systems (1987) 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, (1987) Edward B. Roche, ed., American Pharmaceutical Association and Pergamon Press. The term "prodrug"
means a compound (e.g, a drug precursor) that is transformed in vivo to yield a compound of Formula (I) or a pharmaceutically acceptable salt, hydrate or solvate of the compound. The transformation may occur by various mechanisms (e.g., by metabolic or chemical processes), such as, for example, through hydrolysis in blood.
A discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, "Pro-drugs as Novel Delivery Systems," Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.
For example, if a compound of Formula (I) or a pharmaceutically acceptable salt, hydrate or solvate of the compound contains a carboxylic acid functional group, a prodrug can comprise an ester formed by the replacement of the hydrogen atom of the acid group with a group such as, for example, (Cj-C$)alkyl, (C2-C12)alkanoyloxymethyl, 1-(alkanoyloxy)ethyl having from 4 to 9 carbon atoms, 1-methyl-1-(alkanoyloxy)-ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N-(CI-C2)alkylamino(C2-C3)alkyi (such as /3-dimethylaminoethyl), carbamoyl-(CI-C2)alkyl, N,N-di (Cl-C2)alkylcarbamoyl-(C1-C2)alkyl and piperidino-, pyrrolidino- or morpholino(C2-C3)alkyl, and the like.
Similarly, if a compound of Formula (I) contains an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a group such as, for example, (CI-C6)alkanoyloxymethyl, 1-((Cl-C6)alkanoyloxy)ethyl, 1-methyl-l-((Cl-C6)alkanoyloxy)ethyl, (Cl-C6)alkoxycarbonyloxymethyl, N-(Cl-C6)alkoxycarbonylaminomethyl, succinoyl, (Cl-C6)alkanoyl, a-amino(Cj-C4)alkanyl, arylacyl and a-aminoacyl, or a-aminoacyl-a-aminoacyl, where each a-aminoacyl group is independently selected from the naturally occurring L-amino acids, P(O)(OH)2, -P(O)(O(C1-C6)alkyl)2 or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate), and the like.
If a compound of Formula (I) incorporates an amine functional group, a prodrug can be formed by the replacement of a hydrogen atom in the amine group with a group such as, for example, R-carbonyl, RO-carbonyl, NRR'-carbonyl where R
and R' are each independently (CI-Clo)alkyl, (C3-C7) cycloalkyl, benzyl, or R-carbonyl is a natural a-aminoacyl or natural a-aminoacyl, -C(OH)C(O)OY' wherein Y' is H, (Cl-C6)alkyl or benzyl, -C(OY2)Y3 wherein Y2 is (Cl-C4) alkyl and Y3 is (Cl-C6)alkyl, carboxy P-C6)alkyl, amino(CI-C4)alkyl or mono-N-or di-N,N-(Ci-C6)alkylaminoalkyl, -C(Y4)Y5 wherein Y4 is H or methyl and Y5 is mono-N- or di-N,N-(CI-C6)alkylamino morpholino, piperidin-1-yl or pyrrolidin-1-yl, and the like.
"Solvate" means a physical association of a compound of this invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal laftice of the crystalline solid. "Solvate"
encompasses both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like. "Hydrate" is a solvate wherein the solvent molecule is H20.
One or more compounds of the invention may also exist as, or optionally converted to, a solvate. Preparation of solvates is generally known. Thus, for example, M. Caira et al, J. Pharmaceutical Sci., 93(3), 601-611 (2004) describe the preparation of the solvates of the antifungal fluconazole in ethyl acetate as well as from water. Similar preparations of solvates, hemisolvate, hydrates and the like are described by E. C. van Tonder et al, AAPS PharmSciTech., 5(1), article 12 (2004);
and A. L. Bingham et al, Chem. Commun., 603-604 (2001). A typical, non-limiting, process involves dissolving a compound in desired amounts of the desired solvent (organic or water or mixtures thereof) at a higher than ambient temperature, and cooling the solution at a rate sufficient to form crystals which are then isolated by standard methods. Analytical techniques such as, for example I. R.
spectroscopy, show the presence of the solvent (or water) in the crystals as a solvate (or hydrate).
"Effective amount" or "therapeutically effective amount" is meant to describe an amount of a compound or a composition of the present invention effective in inhibiting HCV protease and/or cathepsins, and thus producing the desired therapeutic, ameliorative, inhibitory or preventative effect in a suitable subject.
The compounds of the present invention can form salts that are also within the scope of this invention. Reference to a compound of the present invention herein is understood to include reference to salts, esters and solvates thereof, unless otherwise indicated. The term "salt(s)", as employed herein, denotes acidic salts formed with inorganic and/or organic acids, as well as basic salts formed with inorganic and/or organic bases. In addition, when a compound of formula I
contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions ("inner salts") may be formed and are included within the term "salt(s)" as used herein.
Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the various formulae of the present invention may be formed, for example, by reacting a compound of the present invention with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization. Acids (and bases) which are generally considered suitable for the formation of pharmaceutically useful salts from basic (or acidic) pharmaceutical compounds are discussed, for example, by S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(l) 1-19; P. Gould, International J. of Pharmaceutics (1986) 201-217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; in The Orange Book (Food & Drug Administration, Washington, D.C. on their website); and P. Heinrich Stahl, Camille G. Wermuth (Eds.), Handbook of Pharmaceutical Salts: Properties, Selection, and Use, (2002) Int'I. Union of Pure and Applied Chemistry, pp. 330-331. These disclosures are incorporated herein by reference thereto.
Exemplary, acid addition salts include acetates, adipates, alginates, ascorbates, aspartates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, cyclopentanepropionates, digluconates, dodecylsulfates, ethanesulfonates, fumarates, glucoheptanoates, glycerophosphates, hemisulfates, heptanoates, hexanoates, hydrochlorides, hydrobromides, hydroiodides, 2-hydroxyethanesulfonates, lactates, maleates, methanesulfonates, methyl sulfates, 2-naphthalenesulfonates, nicotinates, nitrates, oxalates, pamoates, pectinates, persulfates, 3-phenylpropionates, phosphates, picrates, pivalates, propionates, salicylates, succinates, sulfates, sulfonates (such as those mentioned herein), tartarates, thiocyanates, toluenesulfonates (also known as tosylates,) undecanoates, and the like.
Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, aluminum salts, zinc salts, salts with organic bases (for example, organic amines) such as benzathines, diethylamine, dicyclohexylamines, hydrabamines (formed with N,N-bis(dehydroabietyl) ethylenediamine), N-methyl-D-glucamines, N-methyl-D-glucamides, t-butyl amines, piperazine, phenylcyclohexylamine, choline, tromethamine, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g. methyl, ethyl, propyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, dibutyl, and diamyl sulfates), long chain halides (e.g. decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides), aralkyl halides (e.g. benzyl and phenethyl bromides), and others.
All such acid salts and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention. All acid and base salts, as well as esters and solvates, are considered equivalent to the free forms of the corresponding compounds for purposes of the invention.
Pharmaceutically acceptable esters of the present compounds include the following groups: (1) carboxylic acid esters obtained by esterification of the hydroxy groups, in which the non-carbonyl moiety of the carboxylic acid portion of the ester grouping is selected from straight or branched chain alkyl (for example, acetyl, n-propyl, t-butyl, or n-butyl), alkoxyalkyl (for example, methoxymethyl), aralkyl (for example, benzyl), aryloxyalkyl (for example, phenoxymethyl), aryl (for example, phenyl optionally substituted with, for example, halogen, C1_4alkyl, or C1_4alkoxy or amino); (2) sulfonate esters, such as alkyl- or aralkylsulfonyl (for example, methanesulfonyl); (3) amino acid esters (for example, L-valyl or L-isoleucyl);
(4) phosphonate esters and (5) mono-, di- or triphosphate esters. The phosphate esters may be further esterified by, for example, a C1_20 alcohol or reactive derivative thereof, or by a 2,3-di (C6_24)acyl glycerol.
In such esters, unless otherwise specified, any alkyl moiety present preferably contains from I to 18 carbon atoms, particularly from 1 to 6 carbon atoms, more particularly from 1 to 4 carbon atoms. Any cycloalkyl moiety present in such esters preferably contains from 3 to 6 carbon atoms. Any aryl moiety present in such esters preferably comprises a phenyl group.
The present invention provides controlled-release pharmaceutical formulations comprising the inventive peptides as an active ingredient and a controlled-release carrier. Because of their HCV inhibitory activity, such pharmaceutical compositions possess utility in treating hepatitis C and related disorders.
Another embodiment of the invention discloses the use of the pharmaceutical formulations disclosed above for treatment of diseases such as, for example, hepatitis C and the like. The method comprises administering a therapeutically effective amount of the inventive pharmaceutical formulation to a patient having such a disease or diseases and in need of such a treatment.
The pharmaceutical formulations of the present invention are suited for treatment of infection by any of the genotypes of HCV. HCV types and subtypes may differ in their antigenicity, level of viremia, severity of disease produced, and response to interferon therapy. (Holland, J. et al., "Hepatitis C genotyping by direct sequencing of the product from the Roche Amplicor Test: methodology and application to a South Australian population," Pathology, 30:192-195, 1998).
The nomenclature of Simmonds, P. et al. ("Classification of hepatitis C virus into six major genotypes and a series of subtypes by phylogenetic analysis of the NS-5 region," J. Gen. Virol., 74:2391-9, 1993) is widely used and classifies isolates into six major genotypes, 1 through 6, with two or more related subtypes, e.g., 1 a, I
b.
Additional genotypes 7-10 and 11 have been proposed, however the phylogenetic basis on which this classification is based has been questioned, and thus types 7, 8, 9 and 11 isolates have been reassigned as type 6, and type 10 isolates as type 3.
(Lamballerie, X. et al., "Classification of hepatitis C variants in six major types based on analysis of the envelope 1 and nonstructural 5B genome regions and complete polyprotein sequences," J. Gen. Virol., 78:45-51, 1997). The major genotypes have been defined as having sequence similarities of between 55 and 72% (mean 64.5%), and subtypes within types as having 75%-86% similarity (mean 80%) when sequenced in the NS-5 region. (Simmonds, P. et al., "Identification of genotypes of hepatitis C by sequence comparisons in the core, El and NS-5 regions," J. Gen.
Virol., 75:1053-61, 1994).

In another alternative embodiment, the method of treatment of the present invention can further comprise administering one or more bile acid sequestrants (insoluble anion exchange resins), coadministered with or in combination with the cardiovascular agents and sterol absorption inhibitor(s) discussed above.
Bile acid sequestrants bind bile acids in the intestine, interrupting the enterohepatic circulation of bile acids and causing an increase in the faecal excretion of steroids. Use of bile acid sequestrants is desirable because of their non-systemic mode of action. Bile acid sequestrants can lower intrahepatic cholesterol and promote the synthesis of apo B/E (LDL) receptors which bind LDL from plasma to further reduce cholesterol levels in the blood.
Non-limiting examples of suitable bile acid sequestrants include cholestyramine (a styrene-divinylbenzene copolymer containing quaternary ammonium cationic groups capable of binding bile acids, such as QUESTRAN or QUESTRAN LIGHT cholestyramine which are available from Bristol-Myers Squibb), colestipol (a copolymer of diethylenetriamine and 1-chloro-2,3-epoxypropane, such as COLESTID tablets which are available from Pharmacia), colesevelam hydrochloride (such as WelChol Tablets (poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide) which are available from Sankyo), water soluble derivatives such as 3,3-ioene, N-(cycloalkyl) alkylamines and poliglusam, insoluble quaternized polystyrenes, saponins and mixtures thereof.
Other useful bile acid sequestrants are disclosed in PCT Patent Applications Nos.
WO 97/11345 and WO 98/57652, and U.S. Patents Nos. 3,692,895 and 5,703,188 which are incorporated herein by reference. Suitable inorganic cholesterol sequestrants include bismuth salicylate plus montmorillonite clay, aluminum hydroxide and calcium carbonate antacids.

Also useful with the present invention are methods of treatment that can further comprise administering at least one (one or more) activators for peroxisome proliferator-activated receptors (PPAR). These activators act as agonists for the peroxisome proliferator-activated receptors. Three subtypes of PPAR have been identified, and these are designated as peroxisome proliferator-activated receptor alpha (PPARa), peroxisome proliferator-activated receptor gamma (PPARy) and peroxisome proliferator-activated receptor delta (PPARcS). It should be noted that PPARd is also referred to in the literature as PPARa and as NUCI, and each of these names refers to the same receptor.
PPARa regulates the metabolism of lipids. PPARa is activated by fibrates and a number of medium and long-chain fatty acids, and it is involved in stimulating fl-oxidation of fatty acids. The PPARy receptor subtypes are involved in activating the program of adipocyte differentiation and are not involved in stimulating peroxisome proliferation in the liver. PPARd has been identified as being useful in increasing high density lipoprotein (HDL) levels in humans. See, e.g., WO
97/28149.
PPARa activator compounds are useful for, among other things, lowering triglycerides, moderately lowering LDL levels and increasing HDL levels.
Useful examples of PPARa activators include the fibrates discussed above.
Other exampies of PPARa activators useful with the practice of the present invention include suitable fluorophenyl compounds as disclosed in U.S. No.

A preferred dosage for the administration of a compound of the present invention is about 0.001 to 500 mg/kg of body weight/day of a compound of the present invention or a pharmaceutically acceptable salt or ester thereof. An especially preferred dosage is about 0.01 to 25 mg/kg of body weight/day of a compound of the present invention or a pharmaceutically acceptable salt or ester thereof.
The phrases "effective amount" and "therapeutically effective amount" mean that amount of a compound of the present invention, and other pharmacological or therapeutic agents described herein, that will elicit a biological or medical response of a tissue, a system, or a subject (e.g., animal or human) that is being sought by the administrator (such as a researcher, doctor or veterinarian) which includes alleviation of the symptoms of the condition or disease being treated and the prevention, slowing or halting of progression of one or more of the presently claimed diseases.
The formulations or compositions, combinations and treatments of the present invention can be administered by any suitable means which produce contact of these compounds with the site of action in the body of, for example, a mammal or human.

For administration of pharmaceutically acceptable salts of the above compounds, the weights indicated above refer to the weight of the acid equivalent or the base equivalent of the therapeutic compound derived from the salt.
As described above, this invention includes combinations comprising an amount of at least one compound of the presently claimed methods or a pharmaceutically acceptable salt or ester thereof, and an amount of one or more additional therapeutic agents listed above (administered together or sequentially) wherein the amounts of the compounds/ treatments result in desired therapeutic effect.
When administering a combination therapy to a patient in need of such administration, the therapeutic agents in the combination, or a pharmaceutical composition or compositions comprising the therapeutic agents, may be administered in any order such as, for example, sequentially, concurrently, together, simultaneously and the like. The amounts of the various actives in such combination therapy may be different amounts (different dosage amounts) or same amounts (same dosage amounts). Thus, for illustration purposes, a compound of the present invention and an additional therapeutic agent may be present in fixed amounts (dosage amounts) in a single dosage unit (e.g., a capsule, a tablet and the like).
If formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described herein and the other pharmaceutically active agent or treatment within its dosage range. Compounds of the present invention may also be administered sequentially with known therapeutic agents when a combination formulation is inappropriate. The invention is not limited in the sequence of administration; compounds of the present invention may be administered either prior to or after administration of the known therapeutic agent.
Such techniques are within the skills of persons skilled in the art as well as attending physicians. I
The pharmacological properties of the compounds of this invention may be confirmed by a number of pharmacological assays for measuring HCV viral activity or cathepsin activity, such as are well know to those skilled in the art.
The compositions of the present invention comprise at least one compound of Formulae I to XXVI, as defined above, together with one or more acceptable controlled-release carriers, other adjuvants or vehicles thereof and optionally other therapeutic agents. Each carrier, adjuvant or vehicle must be acceptable in the sense of being compatible with the other ingredients of the composition and not injurious to the mammal in need of treatment.
The compositions of the present invention are formulated with one or more controlled-release carriers to provide the rate controlled-release of any one or more of the components or active ingredients to optimize the therapeutic effects, i.e. HCV
inhibitory activity and the like. Suitable dosage formulations for sustained release include, inter alia, layered tablets containing layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.
Controlled-release is a term known in the medicinal art and is typically used interchangeably with delayed release, slow release, controlled availability, slow acting, extended release, and metered release. Controlled-release is generally defined as the release of an agent from a dosage formulation slowly over a period of time, such as over hours or days. In the present invention, controlled-release is further defined as administering a predetermined dose of at least one of the compounds of Formulae I to XXVI over a predetermined period of time.
The present invention discloses dosage formulations and methods of using the same in which a predetermined dose of at least one of the compounds of Formulae I to XXVI is administered to maintain a suitable therapeutically efficacious trough level Cmin plasma concentration of said one compound throughout the dosing interval. Preferably, in an embodiment, the present invention discloses dosage formulations and methods of using the same in which a predetermined dose of at least one of the compounds of Formulae I to XXVI is administered to maintain the average Cmin plasma concentration of the at least one HCV protease inhibitor at or above about 10ng/ml. However, in other embodiments, the average Cmin plasma concentration of the at least one protease inhibitor may be maintained at or above 50 ng/ml, 100ng/mI, 150ng/ml or 200ng, ml. Cmin is generally defined as the minimum concentration of drug in plasma to obtain a predetermined intensity of response.
Cmin is a measure of the concentration of drug in blood/plasma and is typically quantified at a time when the drug concentration will be near its lowest level, i.e.
before the next predetermined dose of the drug. The controlled-release dosage formulation and method are intended to treat, prevent, and/or ameliorate disorders associated with HCV. The controlled-release dosage formulation and method are further intended to treat and/or reduce the signs and/or symptoms associated with HCV.
The rate of dissolution of the formulation can range suitably to generally allow the dissolution of from about 5 % of the drug in the first 6 hours to about 80% of the drug in the first 6 hours, preferably from about 20 % of the drug in the first 6 hours to about 50% of the drug in the first 6 hours. Dissolution can be determined according to standard USP procedures well known to those skilled in the art. A non-limiting example of a suitable procedure for determining dissolution is described in the following table:

(50 mg) Dissolution Procedure Apparatus USP Apparatus 2 (Paddles) Dissolution 0.5% SDS in phosphate buffer, pH 6.8, 500 mL for 50 Medium mg strength Temperature 37 C
Detection HPLC with UV detector at 220 nm wavelength The controlled-release dosage formulation has at least one dosage unit, but may contain a plurality of dosage units, ranging from 2-100 dosage units. An oral dosage formulation may be provided, such as one of the following: tablets, capsules, or caplets. A transdermal treatment via a medicated patch may also be used as the controlled-release dosage formulation.
The controlled-release dosage formulation contains from about I mg to about 3000mg of at least one HCV protease inhibitor from Formulae I to XXVI
discussed herein. The dosage formulation may be administered once a day, twice a day, three times a day, four times a day, or more frequently. In one non-limiting embodiment, 400mg of the HCV protease inhibitor is administered three times a day.
However, the dosing schedule may be at from about 100mg a day, 100mg twice a day, 200mg twice a day, 400mg twice a day, 600mg twice a day, or 600mg three times a day.
Also, as discussed herein, the amount and frequency of administration of the formulations of the present invention will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 50 mg/day to about 3000 mg/day, in two to four divided doses.
The quantity of active compound in a unit dose of preparation may be varied or adjusted from about I mg to about 1000 mg, or from about 50 mg to about 800 mg, or from about 50 mg to about 600 mg, or from about 50 mg to about 400 mg, or from about 50 mg to about 200 mg according to the particular application. In one embodiment, the dosage formulation contains about 200 mg of the active compound.
The controlled-release dosage formulation may be administered at a time of day to coincide with the circadian rhythm of the subject being treated.
Circadian rhythms are endogenous oscillations that occur with a periodicity of about 24 hours, and are synchronized according to internal biologic clocks related to the sleep-wake cycle. The controlled-release dosage formulation thus may be administered in one or more discrete dosages over a twenty-four hour time interval in an asymmetric pattern as to dosage amount and/or timing of dosage, wherein the at least one HCV
protease inhibitor is selected from the group consisting of compounds of Formulae I-XXVI, as described above.
Studies of viral activity in HCV infected patients indicate that viral activity and resulting viral load are influenced by the circadian rhythm of the patient. As shown in Fig. 1, in patients treated with compound Ia of the present invention the decline in viral load is cyclical, with the viral load declining during cell division in the liver, and increasing at times when no cell division is occurring. During cell division the virus is unable to replicate, and the viral load declines. Thus, in one aspect of the invention, the one or more discrete dosages are adjusted in amount to provide a highest dose or doses at a time or times corresponding to the time interval when replication of the hepatitis-C virus is highest.
It has been determined that metabolism of compounds of the present invention is also affected by the patient's circadian rhythm. As shown in Fig. 2 (right hand box), plasma levels of the drug are highest in the morning, when measured 8 hours after the previous dose and before the morning dose is administered. Plasma levels 8 hours after the morning dose are much lower, suggesting that metabolism of the drug is faster during the day than at night.
Accordingly, in another aspect of the present invention, the one or more discrete dosages are adjusted in amount to provide a highest dose or doses at a time or times corresponding to the time interval when metabolism of the protease inhibitor is highest. In a preferred embodiment, the one or more discrete dosages is three doses, administered as one dose of 300 mg., one dose of 400 mg., and one dose of 500 mg., each dose administered every 8 hours, wherein the 500 mg.
dose is administered at a time corresponding to the time interval of highest replication of the hepatitis-C virus and/or highest metabolism of the protease inhibitor. It may also be desirable to provide different patterns of dosage, such as, but not limited to 200, 300, 700; or 200, 200, 300, 500; 200, 200, 200, 600, or other combinations, depending on considerations such as the length of time that highest viral replication is occurring, metabolism of the protease inhibitor and the highest tolerated dose.
One skilled in the art can determine the appropriate number of doses and dose amounts without undue experimentation.
Alternatively, and in additional embodiments, the one or more discrete dosages is administered in equal dose amounts but staggered as to timing of administration, to accommodate fluctuations in viral load and/or drug metabolism.
For example, if the total desired dose over 24 hours is 1200 mg., it can be administered as a 300 mg/dose, at 8 am, 12 noon, 4 pm, and 8 pm, with a 12-hour interval between the evening dose and the morning dose. This example is non-limiting, and one skilled in the art can easily determine the appropriate number of doses and the timing of administration. In a preferred embodiment, the one or more discrete dosages is at least three doses in equal amounts, administered at unequal time intervals in twenty-four hours. The time intervals of dosage are adjusted to provide administration of one or more doses at a time or times corresponding to the time interval of highest replication of the hepatitis-C virus, or they can be adjusted to provide administration of one or more doses at a time or times corresponding to the time interval of highest metabolism of the protease inhibitor.
As will be understood by one skilled in the art, both the amount of dosage given over a 24-hour period and the timing of administration can be varied in an asymmetric pattern. The asymmetric pattern of dose amount or timing of dosage is adjusted to accommodate variations in viral replication and/or metabolism of the protease inhibitor influenced by the patient's circadian rhythm.
Further, as discussed herein, the controlled-release dosage formulation may be administered concurrently or sequentially as combination therapy with at least one of an antiviral agent and/or at least one of an immunomodulatory agent that are different from the HCV protease inhibitors disclosed in Formulae I to XXVI.
Further, the different antiviral agent(s) and/or the immunomodulatory agent(s) may be contained within the controlled-release dosage formulation with the HCV
protease inhibitors disclosed in Formulae I to XXVI. As discussed herein, the controlled-release dosage formulation may contain at least one anti-cancer agent or may be administered concurrently or sequentially with at least one anti-cancer agent.
In the pharmaceutical compositions and methods of the present invention, the active ingredients will typically be administered in admixture with suitable carrier materials suitably selected with respect to the intended form of administration, i.e.
oral tablets, capsules (either solid-filled, semi-solid filled or liquid filled), powders for constitution, oral gels, elixirs, dispersible granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral non-toxic pharmaceutically acceptable inert carrier, such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid forms) and the like.
Moreover, when desired or needed, suitable binders, lubricants, disintegrating agents and coloring agents may also be incorporated in the mixture. Powders and tablets may be comprised of from about 5 to about 95 percent inventive composition.

In one non-limiting embodiment, the controlled-release carrier is a swellable polymer. The swellable polymer is a biocompatible or bioerodible, hydrophilic polymer, preferably a cellulosic polymer. The term "hydrophilic" is generally defined in terms of a partition coefficient P, which is the ratio of the equilibrium concentration of a compound in an organic phase to that in an aqueous phase. A hydrophilic compound has a P value less than 1.0, typically less than about 0.5, where P
is the partition coefficient of the compound between octanol and water. Hydrophilic polymeric carriers are thus compatible with aqueous fluids such as those present in the human body.
The term "polymer" as used herein refers to a molecule containing a plurality of covalently attached monomer units, and includes branched, dendrimeric and star polymers as well as linear polymers. The term also includes both homopolymers and copolymers, e.g., random copolymers, block copolymers and graft copolymers, as well as uncrosslinked polymers and slightly to moderately to substantially crosslinked polymers.
The terms "swellable" and "bioerodible" (or simply "erodible") are used to refer to the preferred polymers herein, with "swellable" polymers being those that are capable of absorbing water and physically swelling as a result, with the extent to which a polymer can swell being determined by the degree of crosslinking, and "bioerodible" or "erodible" polymers referring to polymers that slowly dissolve and/or gradually hydrolyze in an aqueous fluid, and/or that physically erodes as a result of movement within the stomach or gastrointestinal tract.
Polymers suitable for use in the present invention are those that both swell upon absorption of gastric fluid and gradually erode over a time period of hours.
Erosion initiates simultaneously with the swelling process, upon contact of the surface of the dosage formulation with gastric fluid. Erosion reflects the dissolution of the polymer beyond the polymer gel-solution interface where the polymer has become sufficiently dilute that it can be transported away from the dosage formulation by diffusion or convection. This may also depend on the hydrodynamic and mechanical forces present in the gastrointestinal tract during the digestive process. While swelling and erosion occur at the same time, it is preferred herein that drug release should be erosion-controlled, meaning that the selected polymer should be such that complete drug release occurs primarily as a result of erosion rather than swelling and dissolution. However, swelling should take place at a rate that is sufficiently fast to allow the tablet to be retained in the stomach.
At minimum, for an erosional gastric retentive dosage formulation, there should be an extended period during which the dosage formulation maintains its size before it is diminished by erosion.
Suitable polymers for use in the present dosage formulations may be linear, branched, dendrimeric, or star polymers, and include synthetic hydrophilic polymers as well as semi-synthetic and naturally occurring hydrophilic polymers. The polymers may be homopolymers or copolymers, if copolymers, either random copolymers, block copolymers or graft copolymers. Synthetic hydrophilic polymers useful herein include, but are not limited to:
polyalkylene oxides, particularly poly(ethylene oxide), polyethylene glycol and poly(ethylene oxide)-poly(propylene oxide) copolymers;
cellulosic polymers;
acrylic acid and methacrylic acid polymers, copolymers and esters thereof, preferably formed from acrylic acid, methacrylic acid, methyl acrylate, ethyl acrylate, methyl methacrylate, ethyl methacrylate, and copolymers thereof, with each other or with additional acrylate species such as aminoethyl acrylate;
maleic anhydride copolymers;
polymaleic acid;
poly(acrylamides) such as polyacrylamide per se, poly(methacrylamide), poly(dimethylacrylamide), and poly(N-isopropyl-acrylamide);
poly(olefinic alcohol) such as poly(vinyl alcohol);
poly(N-vinyl lactams) such as poly(vinyl pyrrolidone), poly(N-vinyl caprolactam), and copolymers thereof;
polyols such as glycerol, polyglycerol (particularly highly branched polyglycerol), propylene glycol and trimethylene glycol substituted with one or more polyalkylene oxides, e.g., mono-, di- and tri-polyoxyethylated glycerol, mono-and di-polyoxyethylated propylene glycol, and mono- and di-polyoxyethylated trimethylene glycol;
polyoxyethylated sorbitol and polyoxyethylated glucose;
polyoxazolines, including poly(methyloxazoline) and poly(ethyloxazoline);
polyvinylamines;
polyvinylacetates, including polyvinylacetate per se as well as ethylene-vinyl acetate copolymers, polyvinyl acetate phthalate, and the like;
polyimines, such as polyethyleneimine;
starch and starch-based polymers;
polyurethane hydrogels;
chitosan;
polysaccharide gums;
zein; and shellac, ammoniated shellac, shellac-acetyl alcohol, and shellac n-butyl stearate.
The term "cellulosic polymer" is used herein to denote a linear polymer of anhydroglucose. Cellulosic polymers that can be used advantageously in the present dosage formulations include, without limitation, hydroxymethylcellulose, hydroxypropylcellulose, hyd roxyethylcellu lose, hydroxypropyl methylcellulose, methylcellulose, ethylcellulose, cellulose acetate, cellulose acetate phthalate, cellulose acetate trimellitate, hydroxypropyl methylcellulose phthalate, hydroxypropylcellulose phthalate, cellulose hexahydrophthalate, cellulose acetate hexahydrophthalate, carboxymethylcellulose, carboxymethylcellulose sodium, and microcrystalline cellulose. Preferred cellulosic polymers are alkyl-substituted cellulosic polymers that ultimately dissolve in the GI tract in a predictably delayed manner. Preferred alkyl-substituted cellulose derivatives are those substituted with alkyl groups of 1 to 3 carbon atoms each. Examples are methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose, and carboxymethylcellulose and mixtures thereof. In terms of their viscosities, one class of preferred alkyl-substituted celluloses includes those whose viscosity is within the range of about 50 to about 110,000 centipoise as a 2% aqueous solution at 20 C. Another class includes those whose viscosity is within the range of about 800 to about 6,000 centipoise as a 1% aqueous solution at 20 C. Particularly preferred alkyl-substituted celluloses are hydroxyethylcellulose and hydroxypropylmethylcellulose. A presently preferred hyd roxyethyicell u lose is NATRASOL 250HX NF (National Formulary), available from Aqualon Company, Wilmington, Del., USA.
Suitable polymers also include naturally occurring hydrophilic polymers such as, by way of example, proteins such as collagen, fibronectin, albumins, globulins, fibrinogen, fibrin and thrombin; aminated polysaccharides, particularly the glycosaminoglycans, e.g., hyaluronic acid, chitin, chondroitin sulfate A, B, or C, keratin sulfate, keratosulfate and heparin; guar gum; xanthan gum; carageenan;
alginates; pectin; and activated polysaccharides such as dextran and starches.
The aforementioned list of polymers is not exhaustive, and a variety of other synthetic hydrophilic polymers may be used, as will be appreciated by those skilled in the art.
The polymer may include biodegradable segments and blocks, either distributed throughout the polymer's molecular structure or present as a single block, as in a block copolymer. Biodegradable segments are those that degrade so as to break covalent bonds. Typically, biodegradable segments are segments that are hydrolyzed in the presence of water. Biodegradable segments may be composed of small molecular segments such as ester linkages, anhydride linkages, ortho ester linkages, ortho carbonate linkages, amide linkages, phosphonate linkages, etc.
Any polymer or polymers of the matrix may also be crosslinked, with the degree of crosslinking directly affecting the rate of polymer swelling as well as the erosion rate. That is, a polymer having a higher degree of crosslinking will exhibit less swelling and slower erosion than a polymer having a lower degree of crosslinking. Crosslinked polymers may be prepared using the above-mentioned exemplary polymers using conventional crosslinking procedures (e.g., chemical crosslinking with an added crosslinking agent, photolytically induced crosslinking, etc.), or the polymers may be obtained commercially in crosslinked form.
The water-swellable polymers can be used individually or in combination.
Certain combinations will often provide a more controlled release of the drug than their components when used individually. Examples include, but are not limited to, the following: a cellulosic. polymer combined with a gum, such as hydroxyethylcellulose or hydroxypropylcellulose combined with xanthan gum; a polyalkylene oxide combined with a gum, such as poly(ethylene oxide) combined with xanthan gum; and a polyalkylene oxide combined with a cellulosic polymer, such as poly(ethylene oxide) combined with hydroxyethylcellulose or hydroxypropylcellulose.
Combinations of different poly(ethylene oxide)s are also contemplated, with polymers of different molecular weights contributing to different dosage formulation characteristics. For example, a very high molecular weight poly(ethylene oxide) such as Polyox 303 (with a number average molecular weight of 7 million) or Polyox Coag (with a number average molecular weight of 5 million) may be used to significantly enhance diffusion relative to disintegration release by providing high swelling as well as tablet integrity. Incorporating a lower molecular weight poly(ethylene oxide) such as Polyox WSR N-60K (number average molecular weight approximately 2 million) with Polyox 303 and/or Polyox Coag increases disintegration rate relative to diffusion rate, as the lower molecular weight polymer reduces swelling and acts as an effective tablet disintegrant. Incorporating an even lower molecular weight poly(ethylene oxide) such as Polyox WSR N-80 (number average molecular weight approximately 200,000) further increases disintegration rate.
The hydrophilicity and water swellability of these polymers cause the drug-containing matrices to swell in size in the gastric cavity due to ingress of water in order to achieve a size that will be retained in the stomach when introduced during the fed mode. These qualities also cause the matrices to become slippery, which provides resistance to peristalsis and further promotes their retention in the stomach.
The release rate of a drug from the matrix is primarily dependent upon the rate of water imbibition and the rate at which the drug dissolves and diffuses from the swollen polymer, which in turn is related to the solubility and dissolution rate of the drug, the drug particle size and the drug concentration in the matrix.
The amount of polymer relative to the drug can vary, depending on the drug release rate desired and on the polymer, its molecular weight, and excipients that may be present in the formulation. The amount of polymer will be sufficient however to retain at least about 40% of the drug within the matrix one hour after ingestion (or immersion in the gastric fluid). Preferably, the amount of polymer is such that at least 50% of the drug remains in the matrix one hour after ingestion. More preferably, at least 60%, and most preferably at least 80%, of the drug remains in the matrix one hour after ingestion. In all cases, however, substantially all of the drug will be released from the matrix within about eight hours, and preferably within about six hours, after ingestion, "substantially all" meaning at least 85%, preferably at least 90%.
Higher molecular weight polymers may be preferred to provide a desired extended release profile using the present dosage formulations. Suitable molecular weights are generally in the range of about 5,000 to about 20,000,000. For sparingly soluble drugs, the polymers have molecular weights preferably in the range of about 5,000 to about 8,000,000, more preferably in the range of about 10,000 to about 5,000,000. For water-soluble drugs, the polymers preferably have molecular weights of at least about 10,000, but the molecular weight used will vary with the selected polymer. For example, for hydroxypropyl methyicellulose, the minimum molecular weight may be as low as 10,000, while for poly(ethylene oxide)s the molecular weight may be far higher, on the order of 2,000,000 or more.
The swellable polymer used as the controlled-release dosage formulation carrier is preferably present in an amount to obtain a weight gain level of the dosage formulation from about 1 to 90 percent, or about 2 to 50 percent, or more preferably about 2 to 25 percent. The swellable polymer used as the controlled-release dosage formulation carrier is also preferably present at from about 1 to 99 weight percent (wt.%), or about 2 to 98 weight percent (wt.%), or more preferably about 20 to weight percent (wt.%).
The formulations of the present invention comprise at least one HCV protease inhibitor, as defined above, together with one or more pharmaceutically acceptable adjuvants and optionally other therapeutic agents and pharmaceutically acceptable carriers and excipients. Each excipient must be acceptable in the sense of being compatible with the other ingredients of the formulation and not injurious to the mammal in need of treatment.
In yet another embodiment, the present invention discloses methods for preparing the pharmaceutical formulations of the present invention. In the pharmaceutical formulations, the HCV protease inhibitor will typically be administered in admixture with suitable carrier materials suitably selected with respect to the intended form of administration, i.e. oral tablets, capsules (either solid-filled, semi-solid filled or liquid filled), powders for constitution, oral gels, elixirs, dispersible granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral non-toxic pharmaceutically acceptable inert carrier, such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid forms) and the like. Powders and tablets may be comprised of from about 5 to about 95 percent of the HCV protease inhibitor.
In one embodiment, the adjuvant is at least one pharmaceutically acceptable surfactant or at least one acidifying agent or both. When desired or needed, suitable carriers and other excipients (such as binders, glidents, lubricants, and disintegrants) may also be incorporated in the formulation. These adjuvants, carriers and excipients as well as others are described hereinafter.
Surfactant refers to an adjuvant material that reduces the contact angle of the active drug component and may also be referred to as a wetting agent.
Typically, the present HCV protease inhibitors have relatively low solubilities in aqueous systems (as in a mammalian body), such as less than 1 mg/ml. For example, the solubility of a compound of Formula 1 a in water is about 0.6 mg/mI. Treatment of diseases requiring high dosages of the present compounds, such as HCV, is enhanced by improving the absorption rate of the compounds thereby improving the extent of absorption of the compounds in a mammal. The surfactant in the pharmaceutical formulations of the present invention enhances wetting of the present compounds and improves the dissolution rate of the compounds to render a greater quantity of the compounds available for absorption than is available in a formulation of the present corripounds that does not include a surfactant. Any pharmaceutically acceptable surfactant that improves wetting of the present compounds may be used. Particularly suitable surfactants include sodium lauryl sulfate, stearic acid, monoethanolamine, docusate sodium, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, ethoxylated aliphatic alcohols, propylene glycol monocaprylate, glycerol monostearate, medium chain triglycerides, polyoxyethylene alkyl ethers, and polyoxyethylene stearates. In one embodiment, the surfactant is sodium lauryl sulfate. In another embodiment, the surfactant is a polyoxyethylene sorbitan fatty acid ester. In yet another embodiment, the surfactant is PEG-1-PEG-9-lauryl glycol ether. These surfactants may be used alone in or combination in the pharmaceutical formulations of the present invention in a total amount of about 0.1 to about 10% by weight or about I to about 5% by weight.
Acidifying agent refers to an adjuvant material that lowers the pH of the formulation. The present compounds are known to generally be most stable at acidic pH. Any pharmaceutically acceptable acidifying agent that improves wetting of the present compounds may be used. Particularly suitable acidifying agents include tartaric acid, ascorbic acid, citric acid, malic acid and succinic acid. In one embodiment, the acidifying agent is tartaric acid. These acidifying agents may be used alone in or combination in the pharmaceutical formulations of the present invention in a total amount of about 0.1 to about 10% by weight or about I to 5% by weight.
Carrier refers to a substance that usually makes up the major portion of the composition or dosage formulation. Suitable carriers include celluloses such as microcrystalline cellulose; sugars such as lactose, sucrose, mannitol and sorbitol;
and starches derived from wheat, corn, rice and potato. The amount of carrier in the formulation can range from about 10 to about 90% by weight of the total formulation, or about 25 to about 75% by weight, or about 30 to about 60% by weight, or about 12 to about 60% by weight. In one embodiment, the carrier is microcrystalline cellulose.
Binders refers to substances that bind or "glue" powders together and make them cohesive by forming granules, thus serving as the "adhesive" in the formulation. Binders add cohesive strength already available in the diluent or bulking agent. Suitable binders include sugars such as lactose, sucrose and corn sweeteners; starches derived from wheat, corn rice and potato; natural gums such as acacia, gelatin and tragacanth; derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate; cellulosic materials such as methylcellulose and sodium carboxymethylcellulose and hydroxypropylmethylcellulose; polyvinylpyrrolidone; polyethylene glycol; waxes and inorganics such as magnesium aluminum silicate. The amount of binder in the formulation can range from about 10 to about 90% by weight of the total formulation, or about 25 to about 75% by weight, or about 30 to about 60% by weight, or about 12 to about 60% by weight. In one embodiment, the binder is anhydrous lactose.
Glidents refers to material that prevents caking and improves the flow characteristics of granulations, so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the formulation can range from about 0.1 % to about 5% by weight of the total formulation, or from about 0.5 to about 3% by weight.
Lubricants are substances added to the dosage formulation to enable the tablet, granules, etc. after it has been compressed, to release from the mold or die by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate or potassium stearate; stearic acid; high melting point waxes; and water soluble lubricants such as boric acid sodium chloride, sodium benzoate, sodium acetate, sodium chloride sodium oleate, polyethylene glycols and d'i-leucine. Lubricants are usually added at the very last step before compression, since they must be present on the surfaces of the granules and in between them and the parts of the tablet press. The amount of lubricant in the formulation can range from about 0.1 to about 10% by weight of the formulation, or from about 0.5 to about 5% by weight.
Disintegrant refers to materials added to the formulation to help it break apart (disintegrate) and release the drug. Suitable disintegrants include starches;
"cold water soluble" modified starches such as sodium carboxymethyl starch; natural and synthetic gums such as locust bean, karaya, guar gum, tragacanth and agar;
cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose;
microcrystalline celluloses and cross-linked microcrystalline celluloses such as sodium croscarmellose; alginates such as alginic acid and sodium alginate;
clays such as bentonites; and effervescent mixtures. The amount of disintegrant in the composition can range from about 2 to about 15% by weight of the formulation, or from about 2 to about 10% by weight.
Coloring agents provide coloration to the formulation or the dosage formulation. Such excipients can include food grade dyes and food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent can vary from about 0.1 to about 5% by weight of the formulation, or from about 0.1 to about 1%.
Sweetening agents, flavoring agents, stabilizers, antioxidants and preservatives may also be included where appropriate.
The term pharmaceutical formulation encompasses both the bulk formulation and individual unit dosage formulations. The bulk composition is material that has not yet been formed into individual dosage units. An illustrative dosage unit is an oral dosage unit such as tablets, capsules and the like.
The formulations of the present invention may be administered orally or transdermally. Preferably, the pharmaceutical formulation is in a unit dosage formulation. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active components, e.g., an effective amount to achieve the desired purpose. Suitable unit dosage formulations are solids, gels, or fluids. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories.
The powders, tablets and capsules may be comprised of from about 5 to about 95 percent active ingredient. Tablets, powders, cachets and capsules can be used as solid dosage formulations suitable for oral administration. Other examples of pharmaceutically acceptable carriers and methods of manufacture for various compositions may be found in A. Gennaro (ed.), Remington's Pharmaceutical Sciences, 13t" Edition, (1990), Mack Publishing Co., Easton, Pennsylvania.
Capsules are special - containers or enclosures, often made of methyl cellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing the pharmaceutical formulation. Hard shell capsules are typically made of blends of relatively high gel strength bone and pork skin gelatins. The capsule itself may contain small amounts of dyes, opaquing agents, plasticizers and preservatives.
Tablet refers to a compressed or molded solid dosage formulation containing the pharmaceutical formulation. The tablet can be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation or by compaction.
A gel, such as an oral gel refers to the formulations dispersed or solubilized in a hydrophillic semi-solid matrix.
Suppositories containing the formulations of the present invention may be prepared by melting a low melting wax such as a mixture of fatty acid glycerides such as cocoa butter, and dispersing the components of the formulations homogeneously therein by stirring or similar mixing. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby solidify.
Additionally, the compositions of the present invention may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimize the therapeutic effects, i.e.
HCV
inhibitory activity and the like. Suitable dosage formulations for sustained release include layered tablets containing layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.
Fluid forms may be liquids including solutions, suspensions and emulsions containing the formulations. Non-limiting examples include water or water-propylene glycol solutions for parenteral injections or addition of sweeteners and pacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.
Also included are aerosol preparations of the present invention that are suitable for inhalation. Aerosols may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier such as inert compressed gas, e.g. nitrogen.
Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.
Alternatively, the formulations of the present invention may be prepared in powder blends that can be suspended in water or juices.
Transdermal formulations may take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.
Bioavailability refers to the rate and extent to which the active drug ingredient or therapeutic moiety is absorbed into the systemic circulation from an administered dosage formulation as compared to a standard or control.
Conventional methods for preparing tablets and capsules are known. Such methods include dry methods such as direct compression and compression of granulation produced by compaction, or wet methods or other special procedures. In one embodiment, a capsule containing the pharmaceutical formulation of the present invention is produced by blending the active drug component with some excipients, compacting the mixing such as with a roller compactor, milling the compact, blending the milled material with any remaining excipients and filling the final blend into capsules.

In one embodiment, the pharmaceutical formulation of the present is administered orally and is in a unit dosage formulation. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.
The amount and frequency of administration of the formulations of the present invention will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 50 mg/day to about 3000 mg/day, in two to four divided doses.
The quantity of active compound in a unit dose of preparation may be varied or adjusted from about I mg to about 1000 mg, or from about 50 mg to about 800 mg, or from about 50 mg to about 600 mg, or from about 50 mg to about 400 mg, or from about 50 mg to about 200 mg according to the particular application. In one embodiment, the dosage formulation contains about 200 mg of the active compound.
The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated.
Determination of the proper dosage regimen for a particular situation is within the skill of the art. For convenience, the total daily dosage may be divided and administered in portions during the day as required.
The amount of drug released over time by the controlled-release carrier is tested by any of the standardized USP Dissolution Tests in vitro. It is desirable to administer the dosage formulation twice a day and to have a relatively constant release of HCV protease inhibitor over a 12 hour period.
The following formulation exemplifies some of the dosage formulations of the present invention. In the formulation, the "Active Compound" designates any of the compounds of Formulae I-XXVI, as defined above, or a pharmaceutically acceptable sale, solvate or ester thereof.
