Definitions

  • 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.
  • HCV protease for example HCV NS3/NS4a serine protease
  • cathepsin activity for example HCV NS3/NS4a serine protease
  • 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%.
  • Hepatitis C virus 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
  • 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.
  • HCV hepatitis A virus
  • HBV hepatitis B virus
  • HDV delta hepatitis virus
  • CMV cytomegalovirus
  • EBV Epstein-Barr virus
  • This approximately 3000 amino acid polyprotein contains, from the amino terminus to the carboxy terminus, a nucleocapsid protein (C), envelope proteins (E1 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.
  • NS4a protein an approximately 6 kda polypeptide
  • NS3/NS4a serine protease activity of NS3 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 (Le., cis) while the other cleavage sites are processed intermolecularly (i.e., trans).
  • NS3/NS4a junction contains a threonine at P1 and a serine at PT.
  • the Cys ⁇ Thr substitution at NS3/NS4a is postulated to account for the requirement of cis rather than trans processing at this junction. See, axL., Pizzi et al. (1994) Proc. Natl. Acad. Sci (USA) _91_:888-892, Failla et al.
  • NS3/NS4a cleavage site is also more tolerant of mutagenesis than the other sites. See, e ⁇ , 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 ⁇ Komoda et al. (1994) J. Virol. 68:7351-7357. lnhibitors 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.
  • Cathepsins 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 Il molecule expression.
  • 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.
  • 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 O 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 O, cathepsin X or cathepsin O2 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.
  • elevated levels of these enzymes in the body can result in pathological conditions leading to disease.
  • 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.
  • 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.
  • osteoclasts which are multinuclear cells of hematopoietic lineage.
  • the normal balance between bone resorption and formation is disrupted, and there is a net loss of bone at each cycle.
  • 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.
  • 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.
  • 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.
  • cathepsin K may also be useful for treating certain neoplastic diseases.
  • 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.
  • 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.
  • the present invention provides a controlled-release dosage formulation for modulating the activity of Hepatitis C virus (HCV) protease in a subject, comprising at least one HCV protease inhibitor and a controlled-release carrier to control the release of the at least one HCV protease inhibitor, comprising administering to said subject an effective amount of at least one HCV protease inhibitor compound of various structural formulae set forth below.
  • HCV protease inhibitor compounds disclosed herein can also be cathepsin inhibitors.
  • the present invention further provides a method for modulating the activity of Hepatitis C virus (HCV) protease in a subject, wherein the method comprises administering to a subject in need of such treatment a dosage form containing at least one HCV protease inhibitor in a pharmaceutically effective amount thereof through a controlled-release formulation of at least one HCV protease inhibitor compound of various structural formulae set forth below.

  • Powders and tablets may be comprised of from about 5 to about 95 percent inventive composition.
  • Suitable controlled-release carrier forms include general types now known or heretofore developed in the art. Examples include and are incorporated herein by reference, but are not limited to, hydrophilic polymers as disclosed in U.S. Patent Application Publication No. 2004/0156899, multi-layer release beads as disclosed in U.S. Patent No. 6,673,367, controlled-release beads as disclosed in U.S. Patent No. 6,770,295, coated tablets as disclosed in U.S. Patent Nos. 4,990,535 and 5,100,675, matrix core tablets as disclosed in U.S. Patent No. 5,314,697, bilayer tablets as disclosed in WO 01/45676, controlled-release beads as disclosed in U.S. Patent No. 6,630,162, and osmotic dosage formulations as disclosed in U.S. Patent Nos. 4,777,049, 4,851 ,229, and 5,178,867.
  • 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.
  • polymer 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.
  • swellable and “bioerodible” 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.

  • 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.
