Description

[Technical Field]

[0001] This disclosure relates to the combination of a CDK9 inhibitor and an anti-HER2 antibody via a linker structure. Pharmaceutical products and special for the administration of specific antibody-drug complexes having combined antitumor drugs A therapeutic use in which heterogeneous antigen-drug complexes and CDK9 inhibitors are administered in combination to the target. Regarding use and method. [Background technology]

[0002] Cyclin-dependent protein kinases (CDKs) bind to cyclin regulatory partners. This corresponds to a family of serine / threonine protein kinases that become active. The CDK / cyclin complex was identified as a regulator of cell cycle progression. The ichrin complex is also involved in transcription and mRNA processing. CDK9 / PTE Fb (positive transcription elongation factor b) is a large subunit of RNA polymerase II (RNAPII). The carboxyl terminal domain (CTD) of the nitrate, mainly Ser-2, is phosphorylated, and the extension of the transcription is enhanced. Adjusts the length. CDK9 inhibition and transcriptional repression result in the lifetime of Mcl1 and c-myc. This leads to the rapid depletion of short mRNA transcripts and related proteins, and their survival proteins This leads to the induction of apoptosis in tumor cells that is overly dependent on quality. Therefore, CDK9 is involved. Targeted transcription CDKs are used in hematological malignancies, such as acute myeloid leukemia and acute lymphoblastic leukemia. High-risk myelodysplastic syndrome, chronic myelomonocytic leukemia, Richter syndrome, B-cell non-Hodgkin's disease Lymphoma, T-cell non-Hodgkin lymphoma, small lymphocytic lymphoma, multiple myeloma, chronic lymphoma Pachycytic leukemia, diffuse large B-cell lymphoma, Burkitt lymphoma, follicular lymphoma And solid tumors, such as breast cancer, gastric cancer, colorectal cancer, lung cancer, esophageal cancer, head and neck cancer, and esophagogastric junction cancer. Cancer, biliary tract cancer, Paget's disease, pancreatic cancer, ovarian cancer, uterine carcinosarcoma, urothelial cancer, prostate cancer, bladder cancer Bladder cancer, gastrointestinal stromal tumor, digestive tract stromal tumor, cervical cancer, squamous cell carcinoma, abdominal cancer, liver cancer, hepatic cell carcinoma Cellular carcinoma, endometrial carcinoma, kidney cancer, vulvar cancer, thyroid cancer, penile cancer, leukemia, malignant lymphoma, phenotype Cell tumors, myelomas, glioblastomas multiforme, osteosarcomas, sarcomas, melanomas, neuroblastomas, and colon cancers Tumors that are heavily dependent on these unstable pro-survival proteins, including but not limited to them. This corresponds to a treatment strategy for treating the disease. CDK9 inhibitors are used for heart disease and viral infections. It may also have therapeutic utility in other disease indications, including diseases, inflammation, and pain. CDK9 inhibitor The harmful agents are disclosed, for example, in the brochure International Publication No. 2017 / 001354.

[0003] Antibody-drug conjugates (ADCs), which consist of a cytotoxic drug combined with an antibody, are effective against cancer cells. It can selectively deliver the drug to cancer cells, thus causing drug accumulation within cancer cells and killing the cancer cells. It is expected that this will occur (Ducry, L., et al., Bioconjugate Chem.(2010)21,5-13;Alley,SC,et al.,Cur rent Opinion in Chemical Biology(2010)14 ,529-537;DamleN.K.Expert Opin.Biol.Ther. (2004)4,1445-1452;Senter PD,et al.,Nat ure Biotechnology(2012)30,631-637;Burris HA.,et al.,J.Clin.Oncol.(2011)29(4):398 -405).

[0004] One such antibody-drug conjugate is trastuzumab deruxtecan, and this It consists of an antibody that targets HER2 and a derivative of exatecan (Ogitan i Y. et al.,Clinical Cancer Research(2016 )22(20),5097-5108;Ogitani Y.et al.,Cance r Science (2016) 107, 1039-1046).

[0005] Despite the therapeutic potential of antibody-drug conjugates and CDK9 inhibitors, antibody-drug conjugates and test results that demonstrate the outstanding efficacy of the combination use of CDK9 inhibitors or No literature has been published that describes any scientific basis suggesting the results of the eel test. In the absence of test results, antibody-drug conjugates together with other cancer treatments such as CDK9 inhibitors Combining these therapies may lead to negative interactions and / or inferior therapeutic outcomes. The possibility exists, and therefore, the outstanding or superior results obtained by such combination treatments. The effect was unpredictable.

[0006] Therefore, to enhance the effectiveness of existing cancer treatments, extend the duration of the therapeutic response, and / or Improvements to therapeutic compositions and methods that can reduce dose-dependent toxicity are still needed. Yes, they are. [Overview of the project] [Means for solving the problem]

[0007] Antibody-drug complex used in this disclosure (inducing the topoisomerase I inhibitor exatecan) Anti-HER2 antibody-drug complexes (including those containing the body) are effective against certain cancers when administered alone, for example. It has been confirmed to exhibit outstanding antitumor effects in the treatment of breast cancer and gastric cancer. Furthermore, CDK9 inhibitors have been shown to exhibit antitumor effects in the treatment of certain cancers. However, enhanced efficacy, prolonged duration of therapeutic response, and / or dose-dependent reduction of toxicity. To provide drugs and treatments that can achieve excellent antitumor effects in cancer treatment, such as those mentioned above. This is desirable.

[0054] 1. Antibody-drug complex The antibody-drug complex used in this disclosure has the following formula: [ka] (In the formula, A represents the binding site to the antibody.) The drug linker represented by is conjugated to the anti-HER2 antibody via thioether linkage. It is an antibody-drug complex.

[0055] In this disclosure, a partial structure consisting of a linker and a drug in an antibody-drug complex is defined as "drug- It is called a "linker". A drug-linker is an interchain disulfide bond site in an antibody. Thiol groups formed at two sites between the heavy chains and two sites between the heavy chain and the light chain ( When replaced, it is linked to the sulfur atom of the cysteine ​​residue.

[0056] The drug linker in this disclosure is exatecan (IUPAC name: (1S,9S)-1-amino -9-ethyl-5-fluoro-1,2,3,9,12,15-hexahydro-9-hydro Xy-4-methyl-10H,13H-benzo[de]pyrano[3',4':6,7]indo Lisino[1,2-b]quinoline-10,13-dione, (Chemical name: (1S,9S)-1- Amino-9-ethyl-5-fluoro-2,3-dihydro-9-hydroxy-4-methyl- 1H,12H-benzo[de]pirano[3',4':6,7]indridino[1,2-b] It is composed of quinoline (also represented as quinoline-10,13(9H,15H)-dione) It contains and is a topoisomerase I inhibitor. Exatecan has the following formula: [ka] It is a camptothecin derivative that has an antitumor effect as represented by [the formula shown].

[0057] The anti-HER2 antibody-drug conjugate used in this disclosure has the following formula: [ka] It can also be represented by...

[0058] Here, the drug-linker is linked to the anti-HER2 antibody ("antibody-") via a thioether bond. It is compounded. The meaning of n is called the average number of compounded drug molecules (DAR; drug-to-antibody ratio). This is the same as the one shown, and indicates the average number of complexed drug linkers per antibody molecule. .

[0059] After migrated to cancer cells, the anti-HER2 antibody-drug conjugate used in this disclosure is linked to the linker portion. Cut in minutes, the following equation: [ka] It releases the compound represented by [the formula shown].

[0060] This compound is the source of the antitumor activity of the antibody-drug complex used in this disclosure. It is speculated that it has a topoisomerase I inhibitory effect (Ogitani Y. et al.,Clinical Cancer Research,2016, Oct 15;22(20):5097-5108,Epub 2016 Mar 29 ).

[0061] The anti-HER2 antibody-drug conjugates used in this disclosure are known to exhibit the bystander effect. (Ogitani Y. et al., Cancer Science (2016) )107,1039-1046). The bystander effect is the antibody-drug complex used in this disclosure. However, it is exerted through the process of internalization in cancer cells that express the target, and then released. The compound exerts antitumor effects even on cancer cells that are present in the surrounding area and do not express the target. This bystander effect occurs when an anti-HER2 antibody-drug conjugate is combined with a CDK9 inhibitor in accordance with this disclosure. Even when used in combination, it exhibits excellent antitumor effects.

[0062] 2. Antibodies in antibody-drug complexes The anti-HER2 antibody in the antibody-drug complex used in this disclosure may be derived from any species. Preferably, the antibody is an anti-HER2 antibody derived from human, rat, mouse, or rabbit. If derived from a species other than the specified one, it is preferably chimerized or humanized using well-known techniques. Anti-HER2 antibodies can be polyclonal or monoclonal antibodies, preferably mo It is a noclonal antibody.

[0063] The antibodies in the antibody-drug complexes used in this disclosure preferably target cancer cells. An anti-HER2 antibody having the characteristic of being able to recognize cancer cells, preferably for example. Characteristics of binding to cancer cells, characteristics of internal migration within cancer cells and / or characteristics of cancer cells It is an antibody that possesses cell-destroying activity.

[0064] The binding activity of anti-HER2 antibodies against cancer cells was confirmed using flow cytometry. It is possible. Internal transfer of antibodies to cancer cells is possible (1) secondary antibodies to therapeutic antibodies (fluorescently labeled) ) Assay to visualize antibodies incorporated into cells under fluorescence microscopy using binding ( Cell Death and Differentiation(2008)15,7 51-761), (2) Cells using secondary antibody (fluorescently labeled) conjugation to therapeutic antibody An assay for measuring light intensity incorporated in Molecular Biology of the Cell,Vol.15,5268-5282,December 2 004) or (3) A therapeutic agent that releases toxins upon integration into cells, thereby inhibiting cell growth. Mab-ZAP assay using immunotoxin binding to antibodies (Bio Technique) This can be confirmed using (s 28:162-165, January 2000). Immunology As a toxin, it is a recombinant complex protein of the diphtheria toxin catalytic domain and protein G. It can be used.

[0065] The antitumor activity of anti-HER2 antibodies is determined by their inhibitory activity against cell growth. This can be confirmed in vitro. For example, overexpression of HER2 as a target protein against an antibody. We cultured cancer cell lines and investigated inhibitory activities against lesion formation, colony formation, and spheroid growth. Antibodies are added to the culture system at various concentrations to determine sex. Antitumor activity is measured, for example, by targeting Nude mice transplanted with cancer cell lines highly expressing a protein were given antibodies, and the cancer cells... By determining the change in this state, it can be confirmed in vivo.

[0066] In anti-HER2 antibody-drug conjugates, the compound that is conjugated exerts an antitumor effect. It is desirable, but not essential, that the anti-HER2 antibody itself should have an antitumor effect. The objective is to exert cytotoxic activity of antitumor compounds specifically and selectively against cancer cells. Therefore, anti-HER2 antibodies should possess the property of internalizing into cancer cells in order to move to them. This is important and desirable.

[0067] The anti-HER2 antibody in the antibody-drug conjugate used in this disclosure is known in the art. It can be obtained by procedure. For example, the antibodies of this disclosure can be obtained by using methods commonly used in the art. This is obtained by using an antigenic polypeptide to immunize animals and produce in vivo This includes recovering and purifying the antibodies. The origin of the antigen is not limited to humans; animals such as mice are also included. Immunity can be conferred using antigens derived from non-human animals such as rats. In this case, the interaction with human antigens... The cross-reactivity of antibody binding to heterologous antigens obtained is used for antibodies applicable to human diseases. It may be tested to lean.

[0068] Alternatively, antibody-producing cells that produce antibodies against an antigen, according to methods known in the art. By fusing with myeloma cells (for example, Kohler and Milstein, Natur e(1975) 256, p. 495-497; and Kennet, R. ed., Mono clonal antibodies, p.365-367, Plenum Press NY (1980), established hybridoma, and then developed monoclonal antibody It is possible to obtain this.

[0069] Antigens are genetically modified organisms that produce genes encoding antigenic proteins. It can be obtained by chief cells. Specifically, a vector that enables the expression of the antigen gene is prepared. The antigen is then transferred to a host cell, where it begins to be expressed. The expressed antigen is then purified. Antibodies can be produced using the above-mentioned genetically modified antigen-expressing cells or cell lines that express the antigen. It can also be obtained by methods of conferring immunity to animals.

[0070] The anti-HER2 antibody in the antibody-drug complex used in this disclosure is preferably a chimeric anti-HER2 antibody. Obtained through artificial modification for the purpose of reducing heterogeneity against humans, such as the body or humanized antibodies. It is a recombinant antibody, or preferably a human-derived antibody, i.e., a human antibody gene These antibodies consist only of a sequence. These antibodies can be produced using known methods.

[0071] Chimeric antibodies are antibodies whose antibody variability and constant region originate from different species, for example, mouse antibodies. Alternatively, chimeric antibodies in which the variable region of a rat antibody is linked to the constant region of a human-derived antibody are a typical example. Possible (Proc.Natl.Acad.Sci.USA,81,6851-6855) (1984).

[0072] As a humanized antibody, only the complementarity-determining region (CDR) of a heterologous antibody is incorporated into a human-derived antibody.

Antibodies obtained by this method and antibodies humanized using gene conversion mutagenesis strategies. U.S. Patent No. 5,821,337 may be a typical example.

[0073] As a human antibody, it is a human having a human chromosome fragment containing the genes for the heavy and light chains of the human antibody. Antibodies produced using antibody-producing mice (Tomizuka, K. et a l.,Nature Genetics(1997)16,p.133-143;Kur oiwa, Y. et.al., Nucl. Acids Res. (1998) 26, p. 3447-3448;Yoshida,H.et.al.,Animal Cell T echnology:Basic and Applied Aspects vol. 10, p.69-73 (Kitagawa, Y., Matsuda, T. and Iij ima, S. eds.), Kluwer Academic Publishers, 1 999;Tomizuka,K.et.al.,Proc.Natl.Acad.Sci See .USA(2000)97, pp.722-727, etc., which can be a typical example. Alternatively, antibodies obtained by phage display or selected from human antibody libraries can be used. The antibody being tested (Wormstone, IMet.al, Investigative e Ophthalmology & Visual Science.(2002)4 3(7),p.2301-2308;Carmen,S.et.al.,Briefin gs in Functional Genomics and Proteomics (2002),1(2),p.189-203;Siriwardena,D.et.a i., Ophthalmology (2002) 109(3), pp. 427-431, etc. (See reference) could be a typical example.

Furthermore, it is known that the newly placed proline residue at the carboxyl terminus is amidated. (Analytical Biochemistry,360:75-83(2007 However, such deletions and modifications of the heavy chain sequence affect the antigen-binding affinity and ephrastosis of the antibody. It does not affect receptor function (such as complement activation or antibody-dependent cellular cytotoxicity). In the anti-HER2 antibody described herein, the antibody and the mechanism of the antibody are modified in this manner. Potency fragments are also included, and deletion mutations are characterized by the deletion of one or two amino acids at the carboxyl terminus of the heavy chain. Mutants obtained by amidation of isomorphs and deletion mutants (e.g., carboxyl-terminal proline residues) This also includes heavy chains in which the group is amidated. The type of deletion variant with a deletion at the ruboxyl terminus is determined by antigen-binding affinity and effect. The antibody comprising the two antibodies described herein is not limited to the above variants, as long as the function is preserved. This heavy chain can be one type selected from the group consisting of the full-length heavy chain and the deletion variants described above. There may be two types, either one or one of the combinations selected from there. Each deletion variant The ratio of the amounts of the type of cultured mammalian cells that produce anti-HER2 antibodies according to this disclosure and may be affected by culture conditions; however, in the antibody according to this disclosure, two heavy chains An antibody in which one amino acid residue at the carboxyl terminus is deleted in both parts could be a preferred example. ru.
