FIELD OF THE INVENTION

The present invention relates to a pharmaceutical composition and a kit comprising a combination of a compound represented by Formula (I), a pharmacologically acceptable salt thereof or a solvate thereof (hereinafter, also referred to as a “compound of the invention”) and a substance having a c-kit kinase-inhibiting activity (hereinafter, also referred to as a “c-kit inhibitor”), to a method for treating cancer comprising administering an effective amount of the pharmaceutical composition to a patient, to use of the compound of the invention for producing the pharmaceutical composition, and to the compound of the invention used for the pharmaceutical composition.

BACKGROUND OF THE INVENTION

Examples of conventionally used chemotherapeutic agents for cancer include alkylating agents such as cyclophosphamide, antimetabolites such as methotrexate and fluorouracil, antibiotics such as adriamycin, mitomycin and bleomycin, plant-derived taxol, vincristine and etoposide and metal complexes such as cisplatin. None of them, however, provides sufficient antitumor effect, and thus development of a novel antitumor drug has been strongly desired.
Recently, 4-(4-methylpiperazine-1-ylmethyl)-N-[4-methyl-3-[4-(3-pyridyl)pyrimidine-2-ylamino]phenyl]benzenamide (hereinafter, also referred to as “imatinib” or “STI571”) is known as a c-kit inhibitor (Documents 1 and 2).
In addition, 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide is known as a VEGF receptor kinase inhibitor (Document 3-4).
However, it has not been elucidated yet what kind of antitumor effect can or cannot be obtained with a pharmaceutical composition containing a combination of these substances.

Examples of solvates include hydrates and nonhydrates, preferably hydrates. Examples of solvents include water, alcohols (for example, methanol, ethanol, n-propanol) and dimethylformamide.
Moreover, according to the present invention, the compound represented by Formula (I) may be crystalline or amorphous. If a crystalline polymorph is present, it may be a single product of any one of the crystal forms or a mixture of such forms.
According to the present invention, the compound of the invention and/or the c-kit inhibitor also comprises compounds that generate the compound represented by Formula (I) and/or the c-kit inhibitor by undergoing metabolism such as oxidation, reduction and hydrolysis in vivo.
According to the present invention, an example of the c-kit inhibitor includes an anti-c-kit kinase antibody.
According to the present invention, an anti-c-kit kinase antibody is an antibody that has affinity with c-kit kinase or a partial fragment thereof. Preferably, an anti-c-kit kinase antibody is a neutralizing antibody that recognizes and binds with c-kit kinase to inhibit the vascular endothelial cell growth activity of c-kit kinase. According to the present invention, an anti-c-kit kinase antibody is, for example, a polyclonal antibody, a monoclonal antibody, a chimeric antibody, a single-chain antibody (scFV) (Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85: 5879-83; The Pharmacology of Monoclonal Antibody, vol. 113, Rosenburg and Moore ed., Springer Verlag (1994) pp. 269-315), a humanized antibody, a polyspecific antibody (LeDoussal et al. (1992) Int. J. Cancer Suppl. 7: 58-62; Paulus (1985) Behring Inst. Mitt. 78: 118-32; Millstein and Cuello (1983) Nature 305: 537-9; Zimmermann (1986) Rev. Physiol. Biochem. Pharmacol. 105: 176-260; Van Dijk et al. (1989) Int. J. Cancer 43: 944-9), or antibody fragments such as Fab, Fab′, F(ab′)2, Fc and Fv, preferably a monoclonal antibody. Furthermore, if necessary, an anti-c-kit kinase antibody may be modified with polyethyleneglycol (PEG) or the like. Otherwise, an anti-c-kit kinase antibody may be produced as a fusion protein with β-galactosidase, MBP (maltose binding protein), GST (glutathione S-transferase), GFP (green fluorescence protein) or the like, which can be detected in an ELISA method or the like without using a secondary antibody. An anti-c-kit kinase antibody may be modified by being labeled with biotin or the like such that the antibody can be collected using avidin, streptavidin or the like.
An anti-c-kit kinase antibody may be produced according to a conventional method using c-kit kinase or a partial fragment thereof (hereinafter, also referred to as a “polypeptide fragment of c-kit kinase”), or a cell expressing c-kit kinase or a partial fragment thereof as a sensitized antigen (“Current Protocols in Molecular Biology” (John Wiley & Sons (1987) Section 11.4-11.13)). In this case, a polypeptide fragment of c-kit kinase may be a fusion protein with an Fc region, GST, MBP, GFP, AP (alkaline phosphatase) or the like.
A polyclonal antibody and a monoclonal antibody may be prepared according to a method known by those skilled in the art (Antibodies: A Laboratory Manual, E. Harlow and D. Lane, ed., Cold Spring Harbor Laboratory (Cold Spring Harbor, N.Y., 1988)).
A polyclonal antibody may be obtained, for example, by administering an antigen to a mammal such as a mouse, a rabbit or a rat, collecting blood from this mammal, and separating and purifying an antibody from the collected blood. Immune sensitization methods are known by those skilled in the art, and may be carried out, for example, by administering an antigen once or more. Furthermore, an antigen (a polypeptide fragment of c-kit kinase) may be used by dissolving it in an appropriate buffer such as a buffer containing a complete Freund's adjuvant or a generally used adjuvant such as aluminum hydroxide, although no adjuvant may be used depending on the administration route or conditions.
Blood is taken from the mammal 1-2 months after the last immune sensitization, and separated and purified according to a conventional method such as centrifugation, precipitation using ammonium sulfate or polyethyleneglycol and various chromatographies, thereby obtaining a polyclonal antibody as a polyclonal antiserum.
An example of a method for producing a monoclonal antibody includes a hybridoma technique. The hybridoma technique first sensitizes a mammal in the same manner as in the production of the polyclonal antibody. Preferably, partial blood collection is carried out appropriate days after the sensitization to determine the antibody titer by a known method such as ELISA method.
Subsequently, spleen is removed from the sensitized animal to obtain B cells. Then, the B cells are fused with myeloma cells by a common method to produce antibody-producing hybridomas. The myeloma cells used are not particularly limited and known cells may be used. The method for fusing the cells may be any method selected from methods known in the art such as Sendai virus technique, polyethyleneglycol technique and protoplast technique. The obtained hybridomas are cultured for an appropriate period of time in an HAT medium (a medium containing hypoxanthine, aminopterin and thymidine) by a common method for hybridoma selection. Then, the antibody-producing hybridoma of interest may be screened and cloned.
A known antibody detecting method such as ELISA method or radioimmunoassay method may be used as the screening method, and a method known in the art such as limiting dilution technique, FACS method or the like may be used as the cloning method. The obtained hybridoma may be cultured in an appropriate culture solution, or may be intraperitoneally administered, for example, to a mouse that is compatible with the hybridoma. The desired monoclonal antibody can be isolated and purified from the resulting culture solution or ascites by salt-out, ion-exchange chromatography, gel filtration, affinity chromatography or the like.

Example 1

Combinational Use of Compound of the Invention and c-Kit Inhibitor in Human Cancer Cell Line Subcutaneous Xenograft Model (In Vivo)

Human gastrointestinal stromal tumor cell line GIST882 (supplied by The Brigham and Women's Hospital, Inc.) was cultured in RPMI1640 (containing 10% FBS) in a 5% carbon dioxide incubator to about 80% confluence. Following cultivation, each cell was collected by trypsin-EDTA treatment according to a general method. Using a phosphate buffer containing 50% matrigel, 5×10⁷cells/mL suspension was prepared, and 0.2 mL each of the resulting cell suspension was subcutaneously transplanted into the flank of a nude mouse. Starting from twenty-one days after the transplantation, 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide (10 mg/kg or 30 mg/kg, once a day, for two weeks) and imatinib (160 mg/kg, twice a day, for two weeks) were orally administered alone or in combination. 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide(methanesulfonate) was prepared based on the description of International publication No. 02/32872 pamphlet (WO02/32872). Moreover, imatinib was purchased from Novartis Pharma K.K. The major and minor axes of tumors were measured with Digimatic caliper (Mitsutoyo), and tumor volumes and relative tumor volumes were calculated according to the following formulae.
Tumor Volume (TV)=Major axis of tumor (mm)×(Minor axis of tumor)²(mm²)/2
Relative Tumor Volume (RTV)=Tumor volume on measurement day/Tumor volume on the first administration day
As a result, combined use of 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide and imatinib showed greater antitumor effect than the case where 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide or imatinib was used alone (Tables 1 and 2, FIGS. 1 and 2). Furthermore, combined use of 4-(3-chloro-4-(cyclopropylaminocarbonyl)aminophenoxy)-7-methoxy-6-quinolinecarboxamide and imatinib showed greater antitumor effect than the case where imatinib was used alone (Tables 1 and 2, FIGS. 1 and 2).
