[0001] TROP2-403-PCT01-NP
[0002] A SCORING METHOD FOR AN ANTI-TROP2 ANTIBODY-DRUG CONJUGATE THERAPY
[0003] CROSS-REFERENCE TO RELATED APPLICATIONS
[0004]
[0001] The present application claims the benefit of priority to U.S. Provisional Application No. 63 / 691,362, filed 06 September 2024; and 63 / 776,821, filed 24 March 2025, the content of which are hereby incorporated by references in its entirety for all purpose.
[0005] TECHNICAL FIELD
[0006]
[0002] The present disclosure relates to a method for computing a score indicative of how a cancer patient will respond to a therapy that uses an antibody-drug conjugate having a drug conjugated to an anti-TROP2 antibody via a linker structure.
[0007] BACKGROUND
[0008]
[0003] Assessing a cancer patient’s response probability to a given treatment is an essential step in determining a cancer patient’s treatment regimen. Such an assessment is often based on histological analysis of tissue samples from a cancer patient and involves identifying and classifying cancers using standard grading schemes by trained pathologists. Immunohistochemical (IHC) staining can be used to distinguish markerpositive cells that express a particular protein from marker-negative cells that do not express the protein. IHC staining typically involves multiple dyes, which includes one or more dyes connected to protein-specific antibodies and another dye that is a counterstain. A common counterstain is hematoxylin, which labels DNA and thus stains nuclei.
[0009]
[0004] A protein specific stain or biomarker can be used to identify the regions of the tissue of the cancer patient that are likely to exhibit a response to a predetermined therapy. For example, a biomarker that stains epithelial cells can help to identify the suspected tumor regions. Then other protein specific biomarkers are used to characterize the cells within the cancerous tissue. The cells stained by a specific biomarker can be identified and quantified, and subsequently a score indicating the number of positively stained cells and negatively stained cells can be visually estimated by pathologists. This score can then be compared to scores of other cancer TROP2-403-PCT01-NP patients that have been calculated in the same way. If the response of these other patients to a given cancer treatment is known, the pathologist can predict, based on a comparison of the score calculated for the cancer patient with the scores of the other patients, how likely the cancer patient is to respond to a given treatment. However, visual assessment by pathologists is prone to variability and subjectivity.
[0010]
[0005] One promising cancer treatment involves an antibody-drug conjugate (ADC) having a drug with cytotoxicity conjugated to an antibody, whose antigen is expressed on the surface of cancer cells. The ADC binds to the antigen and undergoes cellular internalization so as to deliver the drug selectively to cancer cells and to accumulate the drug within those cancer cells and kill them. Certain cytotoxic drug, such as deruxtecan (DXd) in datopotamab deruxtecan (Dato-DXd, also known as DS-1062), is known to have high membrane permeability, which is a favorable feature as a payload of ADC to be delivered not only to antibody target positive tumor cells, but also to target negative tumor cells nearby target positive tumor cells by passive diffusion, resulting in potential antitumor efficacy across tumors regardless of antigen expression and heterogeneity, an effect called the bystander antitumor effect. A computer-based method is sought for generating a repeatable and objective score indicating a cancer patient’s response to a treatment involving a therapeutic TROP2 antibody-drug conjugate.

[0053] DETAILED DESCRIPTION
[0054]
[0049] I. Definitions.
[0055]
[0050] To facilitate an understanding of the present disclosure, a number of terms and phrases are defined below. The term "cancer" is used to have the same meaning as that of the term "tumor". In the present disclosure, "TROP2" is synonymous with the calcium signal transducer trophoblast antigen 2 transmembrane protein. In the present disclosure, the term "TROP2 protein" is used in the same meaning as TROP2. The expression of the TROP2 protein can be detected using a method well known to those skilled in the art, such as immunohistochemistry (H4C) or immunofluorescence (IF).
[0056]
[0051] In the present disclosure, "anti-TROP2 antibody" means an antibody that specifically binds to TROP2. The anti-TROP2 antibody has an activity of binding to TROP2-403-PCT01-NP
[0057] TR0P2 and is thereby internalized into TROP2-expressing cells, such that after exhibiting the activity of binding to TR0P2, the antibody moves into the TR0P2 expressing cells. The anti-TROP2 antibody targets tumor cells, binds to the tumor cells, internalizes into the tumor cells, exhibits cytocidal activity against the tumor cells, and can be conjugated with a drug having antitumor activity via a linker to form an antibody-drug conjugate.
[0058]
[0052] An amino acid sequence of a heavy chain of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 1. The heavy chain has the signal sequence (1-19), the variable region (20-140), and the constant region (141-470).
[0059]
[0053] An amino acid sequence of a light chain of an exemplary anti-TROP2 antibody may be presented by SEQ ID NO. 2. The light chain has the signal sequence (1-20), the variable region (21-129), and the constant region (130-234).

[0061]
[0055] An amino acid sequence of CDRL1 of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 6, an amino acid sequence of CDRL2 (SAS) of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 7, and an amino acid sequence of CDRL3 of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 8.
[0062]
[0056] An amino acid sequence of a heavy chain variable region of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO: 9, and an amino acid sequence of a light chain variable region of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 10. An amino acid sequence of another heavy chain of an exemplary anti-TROP2 antibody may be represented by SEQ ID NO. 11.
[0063]
[0057] In one embodiment, an anti-TROP2 antibody of the anti-TROP2 antibodydrug conjugate used in the present disclosure is an antibody comprising a heavy chain comprising CDRH1 consisting of an amino acid sequence represented by SEQ ID NO. 3 (an amino acid sequence consisting of amino acid residues 50 through 54 of SEQ ID NO. 1), CDRH2 consisting of an amino acid sequence represented by SEQ ID NO. 4 (an amino acid sequence consisting of amino acid residues 69 through 85 of TROP2-403-PCT01-NP
[0064] SEQ ID NO. 1) and CDRH3 consisting of an amino acid sequence represented by SEQ ID NO. 5 (an amino acid sequence consisting of amino acid residues 118 through 129 of SEQ ID NO. 1), and a light chain comprising CDRL1 consisting of an amino acid sequence represented by SEQ ID NO. 6 (an amino acid sequence consisting of amino acid residues 44 through 54 of SEQ ID NO. 2), CDRL2 consisting of an amino acid sequence represented by SEQ ID NO. 7 (an amino acid sequence consisting of amino acid residues 70 to 76 of SEQ ID NO. 2) and CDRL3 consisting of an amino acid sequence represented by SEQ ID NO. 8 (an amino acid sequence consisting of amino acid residues 109 through 117 of SEQ ID NO. 2), and in a specific embodiment, an antibody comprising a heavy chain variable region consisting of an amino acid sequence represented by SEQ ID NO. 9 (an amino acid sequence consisting of amino acid residues 20 through 140 of SEQ ID NO. 1) and a light chain variable region consisting of an amino acid sequence represented by SEQ ID NO. 10 (an amino acid sequence consisting of amino acid residues 21 through 129 of SEQ ID NO. 2). In other specific embodiments, the antibody comprises a heavy chain consisting of an amino acid sequence represented by SEQ ID NO. 11 (an amino acid sequence consisting of amino acid residues 20 through 469 of SEQ ID NO. 1) and a light chain consisting of an amino acid sequence represented by amino acid residues 21-234 of SEQ ID NO. 2. In other embodiments, the antibody comprises a heavy chain consisting of an amino acid sequence represented by amino acid residues 20-470 of SEQ ID NO. 1 and a light chain consisting of an amino acid sequence represented by amino acid residues 21-234 of SEQ ID NO. 2.
[0065]
[0058] In the present disclosure, the term "QCS Positive" (QCS+) refers to cancer that is likely to show a response to an anti-TROP2 ADC therapy. The term "QCS Negative" (QCS-) refers to cancer that is unlikely to show a response to an anti- TROP2 ADC therapy. The acronym QCS stands for Quantitative Continuous Score. The result of the novel predictive method of the present disclosure is generally referred to as a Quantitative Continuous Score and may be a response score, a treatment score or an indication of predicted survival time. The QCS score is obtained by performing statistical operations on all of the single-cell ADC scores obtained for a patient. Applying a predetermined threshold to the QCS scores discriminates between “QCS Positive” and “QCS Negative” patients. Stratifying the cancer patients into the QCS Positive and QCS Negative groups enables the TROP2-403-PCT01-NP identification of those QCS+ patients who likely benefit from the therapy which involves the ADC.
[0066]
[0059] II. The anti- TROP2 antibody-drug conjugate.
[0067]
[0060] An exemplary antibody-drug conjugate used in the present disclosure is an antibody-drug conjugate in which a drug-linker represented by the following formula:
[0061] [Formula 1]
[0068]
[0062] wherein A represents the connecting position to an antibody and is conjugated to an anti-TROP2 antibody via a thioether bond.
[0069]
[0063] In the present disclosure, the partial structure consisting of a linker and a drug in the antibody-drug conjugate is referred to as a "drug-linker". The drug-linker is connected to a thiol group (in other words, the sulfur atom of a cysteine residue) formed at an interchain disulfide bond site (two sites between heavy chains, and two sites between a heavy chain and a light chain) in the antibody.
[0070]
[0064] The drug-linker of the present disclosure may include exatecan (IUPAC name: (lS,9S)-l-amino-9-ethyl-5-fluoro-l,2,3,9,12,15-hexahydro-9-hydroxy-4- methyl-10H,13H-benzo[de]pyrano[3',4':6,7]indolizino[l,2-b]quinolin-10,13-dione, (also expressed as chemical name: (lS,9S)-l-amino-9-ethyl-5-fluoro-2,3-dihydro-9- hydroxy-4-methyl-lH,12H-benzo[de]pyrano[3',4':6,7]indolizino[l,2-b]quinolin- 10,13(9H,15H)-dione)), which is a topoisomerase I inhibitor, as a component. Exatecan is a camptothecin derivative having an antitumor effect, represented by the following formula:
[0071]
[0065] [Formula 2] TROP2-403-PCT01-NP
[0072]
[0066] An exemplary anti-TROP2 antibody-drug conjugate used in the present disclosure can be also represented by the following formula:
[0073]
[0067] [Formula 3]
[0074]
[0068] Here, the drug-linker is conjugated to an anti-TROP2 antibody (‘Antibody- ’) via a thioether bond. The meaning of n is the same as that of what is called the average number of conjugated drug molecules (DAR; Drug-to- Antibody Ratio), and indicates the average number of units of the drug-linker conjugated per antibody molecule.
[0075]
[0069] FIG. 12 illustrates a particular anti-TROP2 antibody-drug conjugate datopotamab deruxtecan (DS-1062), with four drug-linker units designated as “DL”. The datopotamab portion of datopotamab deruxtecan shown in FIG. 12 is humanized anti-TROP2 IgGl mAb, wherein IgGl indicates the isotype of the anti-TROP2 antibody.
[0076]
[0070] After migrating into cancer cells, the particular anti-TROP2 antibody-drug conjugate used in the present disclosure is cleaved at the linker portion to release a compound represented by the following formula:
[0071] [Formula 4] TROP2-403-PCT01-NP
[0077]
[0072] The compound shown above is the primary source of antitumor activity of the particular anti-TROP2 antibody-drug conjugate used in the present disclosure, and has a topoisomerase I inhibitory effect.
[0078]
[0073] The particular anti-TROP2 antibody-drug conjugate used in the present disclosure also has a bystander effect in which the anti-TROP2 antibody-drug conjugate is internalized into cancer cells that express the target protein TROP2, and the compound shown above then also exerts an antitumor effect on neighboring cancer cells that do not express the target protein TROP2.
[0079]
[0074] III. The anti-TROP2 antibody in the antibody-drug conjugate.
[0080]
[0075] The anti-TROP2 antibody in the antibody-drug conjugate used in the present disclosure may be derived from any species and is, in a specific embodiment, an antibody derived from a human, a rat, a mouse, or a rabbit. In one specific embodiment, in cases when the antibody is derived from species other than human species, it is chimerized or humanized using a well known technique. The antibody of the present disclosure may be a polyclonal antibody or a monoclonal antibody and, in a particular embodiment, is a monoclonal antibody.
[0081]
[0076] In a specific embodiment, the antibody in the antibody-drug conjugate used in the present disclosure is an antibody having the characteristic of being able to target cancer cells, and is, in one specific embodiment, an antibody possessing, for example, the property of being able to recognize a cancer cell, the property of being able to bind to a cancer cell, the property of being internalized in a cancer cell, and / or cytocidal activity against cancer cells.
[0082]
[0077] The binding activity of the antibody against cancer cells can be confirmed using flow cytometry. The internalization of the antibody into tumor cells can be confirmed using (1) an assay of visualizing an antibody incorporated in cells under a TROP2-403-PCT01-NP fluorescence microscope using a secondary antibody (fluorescently labeled) binding to the therapeutic antibody (Cell Death and Differentiation (2008) 15, 751-761), (2) an assay of measuring a fluorescence intensity incorporated in cells using a secondary antibody (fluorescently labeled) binding to the therapeutic antibody (Molecular Biology of the Cell, Vol. 15, 5268-5282, December 2004), or (3) a Mab-ZAP assay using an immunotoxin binding to the therapeutic antibody wherein the toxin is released upon incorporation into cells to inhibit cell growth (Bio Techniques 28: 162- 165, January 2000). As the immunotoxin, a recombinant complex protein of a diphtheria toxin catalytic domain and protein G may be used.
[0083]
[0078] The antitumor activity of the antibody can be confirmed in vitro by determining inhibitory activity against cell growth. For example, a cancer cell line overexpressing a target protein for the antibody is cultured, and the antibody is added at varying concentrations into the culture system to determine inhibitory activity against focus formation, colony formation, and spheroid growth. The antitumor activity can be confirmed in vivo, for example, by administering the antibody to a nude mouse with a transplanted cancer cell line highly expressing the target protein, and determining changes in the cancer cells.
[0084]
[0079] Since the compound conjugated in the antibody-drug conjugate exerts an antitumor effect, in one embodiment, the antibody itself should have an antitumor effect. For the purpose of specifically and selectively exerting the cytotoxic activity of the antitumor compound against cancer cells, in one specific embodiment, the antibody should have the property of being internalized to migrate into cancer cells.
[0080] The antibody in the antibody-drug conjugate used in the present disclosure can be obtained by a procedure known in the art. For example, the antibody of the present disclosure can be obtained using a method usually carried out in the art, which involves immunizing animals with an antigenic polypeptide and collecting and purifying antibodies produced in vivo. The origin of the antigen is not limited to humans, and the animals may be immunized with an antigen derived from a nonhuman animal such as a mouse, a rat and the like. In this case, the cross-reactivity of antibodies binding to the obtained heterologous antigen with human antigens can be tested to screen for an antibody applicable to a human disease.
[0085]
[0081] Alternatively, antibody -producing cells which produce antibodies against the antigen can be fused with myeloma cells according to a method known in the art TROP2-403-PCT01-NP
[0086] (for example, Kohler and Milstein, Nature (1975) 256, p.495-497; Kennet, R. ed., Monoclonal Antibodies, p.365-367, Plenum Press, N.Y. (1980)), to establish hybridomas, from which monoclonal antibodies can in turn be obtained.
[0087]
[0082] The antigen can be obtained by genetically engineering host cells to produce a gene encoding the antigenic protein. Specifically, vectors that permit expression of the antigen gene are prepared and transferred to host cells so that the gene is expressed. The antigen thus expressed can be purified. The antibody can also be obtained by a method of immunizing animals with the above-described genetically engineered antigen-expressing cells or a cell line expressing the antigen.
[0088]
[0083] In one specific embodiment, the antibody in the antibody-drug conjugate used in the present disclosure is a recombinant antibody obtained by artificial modification for the purpose of decreasing heterologous antigenicity to humans such as a chimeric antibody or a humanized antibody, or is an antibody having only the gene sequence of an antibody derived from a human, that is, a human antibody.
[0089] These antibodies can be produced using a known method.
[0090]
[0084] As the chimeric antibody, an antibody in which antibody variable and constant regions are derived from different species, for example, a chimeric antibody in which a mouse- or rat-derived antibody variable region is connected to a human- derived antibody constant region can be exemplified (Proc. Natl. Acad. Sci. USA, 81, 6851-6855, (1984)).
[0091]
[0085] As the humanized antibody, an antibody obtained by integrating only the complementarity determining region (CDR) of a heterologous antibody into a human- derived antibody (Nature (1986) 321, pp. 522-525), an antibody obtained by grafting a part of the amino acid residues of the framework of a heterologous antibody as well as the CDR sequence of the heterologous antibody to a human antibody by a CDR- grafting method (WO 90 / 07861), and an antibody humanized using a gene conversion mutagenesis strategy (U.S. Patent No. 5821337) can be exemplified.
[0092]
[0086] As the human antibody, an antibody generated by using a human antibodyproducing mouse having a human chromosome fragment including genes of a heavy chain and light chain of a human antibody (see Tomizuka, K. et al., Nature Genetics (1997) 16, p.133-143; Kuroiwa, Y. et. al., Nucl. Acids Res. (1998) 26, p.3447-3448; Yoshida, H. et. al., Animal Cell Technology: Basic and Applied Aspects vol.10, p.69- 73 (Kitagawa, Y., Matsuda, T. and lijima, S. eds.), Kluwer Academic Publishers, TROP2-403-PCT01-NP
[0093] 1999; Tomizuka, K. et. al., Proc. Natl. Acad. Sci. USA (2000) 97, p.722-727, etc.) can be exemplified. As an alternative, an antibody obtained by phage display, the antibody being selected from a human antibody library (see Wormstone, I. M. et. al, Investigative Ophthalmology & Visual Science. (2002) 43 (7), p.2301-2308; Carmen, S. et. al., Briefings in Functional Genomics and Proteomics (2002), 1 (2), p.189-203; Siriwardena, D. et. al., Ophthalmology (2002) 109 (3), p.427-431, etc.) can be exemplified.
[0094]
[0087] In the antibody in the antibody-drug conjugate used in present disclosure, modified variants of the antibody are also included. The modified variant refers to a variant obtained by subjecting the antibody according to the present disclosure to chemical or biological modification. Examples of the chemically modified variant include variants including a linkage of a chemical moiety to an amino acid skeleton, variants including a linkage of a chemical moiety to an N-linked or O-linked carbohydrate chain, etc. Examples of the biologically modified variant include variants obtained by post-translational modification (such as N-linked or O-linked glycosylation, N- or C-terminal processing, deamidation, isomerization of aspartic acid, or oxidation of methionine), and variants in which a methionine residue has been added to the N terminus by being expressed in a prokaryotic host cell. Further, an antibody labeled so as to enable the detection or isolation of the antibody or an antigen according to the present disclosure, for example, an enzyme-labeled antibody, a fluorescence-labeled antibody, and an affinity-labeled antibody are also included in the meaning of the modified variant. Such a modified variant of the antibody according to the present disclosure is useful for improving the stability and blood retention of the antibody, reducing the antigenicity thereof, detecting or isolating an antibody or an antigen, and so on.
[0095]
[0088] Further, by regulating the modification of a glycan which is linked to the antibody according to the present disclosure (glycosylation, defucosylation, etc.), it is possible to enhance antibody-dependent cellular cytotoxic activity. As the technique for regulating the modification of a glycan of antibodies, International Publication No. WO 99 / 54342, International Publication No. WO 00 / 61739, International Publication No. WO 02 / 31140, International Publication No. WO 2007 / 133855, International Publication No. WO 2013 / 120066, etc. are known. However, the technique is not limited thereto. In the antibody according to the present disclosure, antibodies in TROP2-403-PCT01-NP which the modification of a glycan is regulated are also included.
[0096]
[0089] It is known that a lysine residue at the carboxyl terminus of the heavy chain of an antibody produced in a cultured mammalian cell is deleted (Journal of Chromatography A, 705: 129-134 (1995)), and it is also known that two amino acid residues (glycine and lysine) at the carboxyl terminus of the heavy chain of an antibody produced in a cultured mammalian cell are deleted and a proline residue newly located at the carboxyl terminus is amidated (Analytical Biochemistry, 360: 75- 83 (2007)). However, such deletion and modification of the heavy chain sequence do not affect the antigen-binding affinity and the effector function (complement activation, antibody-dependent cellular cytotoxicity, etc.) of the antibody. Therefore, in the antibody according to the present disclosure, antibodies subjected to such modification and functional fragments of the antibody are also included, and deletion variants in which one or two amino acids have been deleted at the carboxyl terminus of the heavy chain, variants obtained by amidation of the deletion variants (for example, a heavy chain in which the carboxyl terminal proline residue has been amidated) and the like are also included. The type of deletion variant having a deletion at the carboxyl terminus of the heavy chain of the antibody according to the present disclosure is not limited to the above variants as long as the antigen-binding affinity and the effector function are conserved. The two heavy chains constituting the antibody according to the present disclosure may be of one type selected from the group consisting of a full-length heavy chain and the above-described deletion variant, or may be of two types in combination selected therefrom. The ratio of the amount of each deletion variant can be affected by the type of cultured mammalian cells that produce the antibody according to the present disclosure and the culture conditions; however, in a specific embodiment, an antibody in which one amino acid residue at the carboxyl terminus has been deleted in both of the two heavy chains in the antibody according to the present disclosure can be exemplified.
[0097]
[0090] As isotypes of the antibody according to the present disclosure, for example, IgG (IgGl, IgG2, IgG3, IgG4) can be exemplified. In one specific embodiment, IgGl or IgG2 can be exemplified.
[0098]
[0091] In the present disclosure, the term "anti-TROP2 antibody" refers to an antibody which binds specifically to TROP2 (TACSTD2: Tumor-associated calcium signal transducer 2; EGP-1), and has an activity of internalization in TROP2- TROP2-403-PCT01-NP expressing cells by binding to TR0P2 in one specific embodiment.
[0099]
[0092] Examples of the anti-TROP2 antibody include hTINAl-HILl (WO 2015 / 098099).
[0100]
[0093] IV. Producing the anti-TROP2 antibody-drug conjugate.
[0101]
[0094] A drug-linker intermediate for use in the production of the antibody-drug conjugate according to the present disclosure is represented by the following formula.
[0102]
[0095] [Formula s]
[0103]
[0096] The drug-linker intermediate can be expressed as the chemical name N-[6- (2,5-dioxo-2,5-dihydro-lH-pyrrol-l-yl)hexanoyl]glycylglycyl-L-phenylalanyl-N-[(2- {[(lS,9S)-9-ethyl-5-fhioro-9-hydroxy-4-methyl-10,13-dioxo-2,3,9,10,13,15- hexahydro-lH,12H-benzo[de]pyrano[3',4':6,7]indolizino[l,2-b]quinolin-l-yl]amino}- 2-oxoethoxy)methyl]glycinamide, and can be produced with reference to descriptions in WO 2014 / 057687, WO 2015 / 098099, WO 2015 / 115091, WO 2015 / 155998, WO 2019 / 044947, and so on.
[0104]
[0097] The antibody-drug conjugate used in the present disclosure can be produced by reacting the above-described drug-linker intermediate and an anti- TROP2 antibody having a thiol group (alternatively referred to as a sulfhydryl group).
[0098] The anti-TROP2 antibody having a sulfhydryl group can be obtained by a method well known in the art (Hermanson, G. T, Bioconjugate Techniques, pp. 56- 136, pp. 456-493, Academic Press (1996)). For example, by using 0.3 to 3 molar equivalents of a reducing agent such as tris(2-carboxyethyl)phosphine hydrochloride (TCEP) per interchain disulfide within the antibody and reacting with the antibody in a buffer solution containing a chelating agent such as ethylenediamine tetraacetic acid TROP2-403-PCT01-NP
[0105] (EDTA), an antibody having a sulfhydryl group with partially or completely reduced interchain disulfides within the antibody can be obtained.
[0106]
[0099] Further, by using 2 to 20 molar equivalents of the drug-linker intermediate per the antibody having a sulfhydryl group, an antibody-drug conjugate in which 2 to 8 drug molecules are conjugated per antibody molecule can be produced.
[0107]
[0100] The average number of conjugated drug molecules per antibody molecule of the antibody-drug conjugate produced can be determined, for example, by a method of calculation based on measurement of UV absorbance for the antibodydrug conjugate and the conjugation precursor thereof at two wavelengths of 280 nm and 370 nm (UV method), or a method of calculation based on quantification through HPLC measurement for fragments obtained by treating the antibody-drug conjugate with a reducing agent (HPLC method).
[0108]
[0101] Conjugation between the antibody and the drug-linker intermediate and calculation of the average number of conjugated drug molecules per antibody molecule of the antibody-drug conjugate can be performed with reference to descriptions in WO 2015 / 098099 and WO 2017 / 002776, for example.
[0109]

In one embodiment, the cancer is selected from group consisting of: lung cancer, breast cancer, colorectal cancer, esophageal cancer, gastric cancer, ovarian cancer, pancreatic cancer, prostate cancer, thyroid cancer, bladder cancer, and uterine cancer. In a specific embodiment, the cancer is lung cancer. In a further specific embodiment, the cancer is non-small cell lung cancer (e.g. non-squamous TROP2-403-PCT01-NP non-small cell lung cancer or squamous non-small cell lung cancer), including nonsmall cell lung cancer with actionable genomic alterations and non-small cell lung cancer without actionable genomic alterations, wherein the actionable genomic alterations include EGFR, ALK, ROS1, NTRK, BRAF, RET, and MET exon 14 skipping (i.e. non-small cell lung cancer without actionable genomic alterations may exclude EGFR, ALK, ROS1, NTRK, BRAF, RET, and MET exon 14 skipping).

These effects can allow cancer patients to be free from symptoms caused by cancer or can achieve an improvement in the QOL of cancer patients and attain a therapeutic effect by sustaining the lives of the cancer patients. Even if the antibody-drug conjugate does not accomplish the killing of cancer cells, it can achieve higher quality of life (QOL) of cancer patients while achieving longer-term survival, by inhibiting or controlling the growth of cancer cells.
[0121]

For example, in the treatment of cancer, the treatment may comprise administering to a subject in need of treatment a therapeutically-effective amount of the antibody-drug conjugate, simultaneously or sequentially with the ionizing radiation or at least one additional therapeutic agent, such as immune checkpoint inhibitors or other chemotherapeutic agents.
[0123]

The antibody-drug conjugate of the present disclosure may be administered for the purpose of reducing tumor size before surgical operation (referred to as preoperative adjuvant chemotherapy or neoadjuvant therapy), or may be administered for the purpose of preventing recurrence of tumor after surgical operation (referred to as postoperative adjuvant chemotherapy or adjuvant therapy).
[0127]
[0119] In further aspects, the antibody-drug conjugate of the present disclosure may be used for the treatment of cancer which is deficient in Homologous Recombination (HR) dependent DNA DSB repair activity. The HR dependent DNA DSB repair pathway repairs double-strand breaks (DSBs) in DNA via homologous mechanisms to reform a continuous DNA helix (K.K. Khanna and S.P. Jackson, Nat. Genet. 27(3): 247-254 (2001)). The components of the HR dependent DNA DSB repair pathway include, but are not limited to, ATM (NM_000051), RAD51 (NM_002875), RAD51L1 (NM_002877), RAD51C (NM_002876), RAD51L3 (NM_002878), DMC1 (NM_007068), XRCC2 (NM_005431), XRCC3 (NM_005432), RAD52 (NM_002879), RAD54L (NM_003579), RAD54B (NM_012415), BRCA1 (NM_007295), BRCA2 (NM_000059), RAD50 (NM_005732), MRE11 A (NM_005590) and NBS1 (NM_002485). Other proteins involved in the HR dependent DNA DSB repair pathway include regulatory factors such as EMSY (Hughes-Davies, et al., Cell, 115, pp523-535). HR components are also described in Wood, et al, Science, 291, 1284-1289 (2001). A cancer that is deficient in HR dependent DNA DSB repair may comprise or consist of one or more cancer cells which have a reduced or abrogated ability to repair DNA DSBs through that pathway, relative to normal cells, i.e., the activity of the HR dependent DNA DSB repair pathway may be reduced or abolished in the one or more cancer cells. The activity of one or more components of the HR dependent DNA DSB repair pathway may be abolished in the one or more cancer cells of an individual having a cancer which is deficient in HR dependent DNA DSB repair. Components of the HR dependent DNA DSB repair pathway are well characterised in the art (see for example, Wood, et al, Science, 291, 1284-1289 (2001)) and include the components listed above.
[0128]
[0120] In some embodiments, the cancer cells may have a BRCA1 and / or a TROP2-403-PCT01-NP
[0129] BRCA2 deficient phenotype, i.e., BRCA1 and / or BRCA2 activity is reduced or abolished in the cancer cells. Cancer cells with this phenotype may be deficient in BRCA1 and / or BRCA2, i.e., expression and / or activity of BRCA1 and / or BRCA2 may be reduced or abolished in the cancer cells, for example by means of mutation or polymorphism in the encoding nucleic acid, or by means of amplification, mutation or polymorphism in a gene encoding a regulatory factor, for example the EMSY gene which encodes a BRCA2 regulatory factor (Hughes-Davies, et al., Cell, 115, 523- 535). BRCA1 and BRCA2 are known tumor suppressors whose wild-type alleles are frequently lost in tumors of heterozygous carriers (Jasin M., Oncogene, 21(58), 8981- 93 (2002); Tutt, et al., Trends Mol Med., 8 (12), 571-6, (2002)). The association of BRCA1 and / or BRCA2 mutations with breast cancer is well-characterised in the art (Radice, P.J., Exp Clin Cancer Res., 21(3 Suppl), 9-12 (2002)). Amplification of the EMSY gene, which encodes a BRCA2 binding factor, is also known to be associated with breast and ovarian cancer. Carriers of mutations in BRCA1 and / or BRCA2 are also at elevated risk of certain cancers, including breast, ovary, pancreas, prostate, hematological, gastrointestinal and lung cancer. In some embodiments, the individual is heterozygous for one or more variations, such as mutations and polymorphisms, in BRCA1 and / or BRCA2 or a regulator thereof. The detection of variation in BRCA1 and BRCA2 is well-known in the art and is described, for example in EP 699 754, EP 705 903, Neuhausen, S.L. and Ostrander, E.A., Genet. Test, 1, 75-83 (1992);
[0130] Chappnis, P.O. and Foulkes, W.O., Cancer Treat Res, 107, 29-59 (2002); Janatova M., et al., Neoplasma, 50(4), 246-505 (2003); Jancarkova, N., Ceska GynekoL, 68{ 1), 11-6 (2003)). Determination of amplification of the BRCA2 binding factor EMSY is described in Hughes-Davies, et / ., Cell, 115, 523-535).
[0131]
[0121] Mutations and polymorphisms associated with cancer may be detected at the nucleic acid level by detecting the presence of a variant nucleic acid sequence or at the protein level by detecting the presence of a variant (i.e. a mutant or allelic variant) polypeptide.

[0126] VI. Method of predicting a patient response to an anti- TROP2 antibody-drug conjugate.
[0136]
[0127] FIG. 1 is an overview of how patient responses to an anti-TROP2 antibody-drug conjugate can be predicted. The normalized membrane optical densities are calculated by taking the mean optical density of staining of the membrane and dividing by the sum of the mean optical density of staining of the membrane plus the mean optical density of staining of the cytoplasm, as shown in FIG. 1 A. An appropriate percentage quantile value can be determined from the distribution of normalized membrane optical density values; illustrative right-skewed and left-skewed distributions with Q75 percentage quantiles are shown in FIG. IB. After choosing an appropriate percentage quantile value, a normalized membrane optical density threshold (cut-off) can be used to determine whether a tissue sample is biomarker positive (BM+) or biomarker negative (BM-); illustrative cut-off of <0.5585 with Q75 percentage quantiles is shown in FIG. 1C, with Cases A and B being determined to be BM+ and Cases C and D being determined to be BM-.
[0128] FIG. 13 is a flowchart of steps 11-17 of a method 10 by which an analysis system analyzes a digital image of tissue from a cancer patient and predicts how the cancer patient will likely respond to a therapy involving an anti-TROP2 antibody-drug conjugate (ADC). The method predicts the response to an ADC of a patient having lung cancer, in particular non-small cell lung cancer (e.g. non- squamous non-small cell lung cancer). In one embodiment, the ADC is datopotamab deruxtecan (DS-1062).
[0137]
[0129] In step 11, a digital image is acquired of a tissue slice from the cancer patient that has been stained via an immunohistochemistry (IHC) staining method, e.g., using a dye linked to a diagnostic antibody that targets the same protein as that targeted by the ADC therapy, in this case the TROP2 protein. To predict the efficacy of the ADC therapy, a diagnostic antibody (e.g., a diagnostic biomarker) with an TROP2-403-PCT01-NP attached dye is used that targets the same protein as that targeted by the ADC therapy. In one embodiment, the anti-TROP2 ADC therapy to which the scoring is directed is an anti-TROP2 antibody conjugated to a drug-linker via a thioether bond, wherein the drug-linker is represented by the formula:
[0138]
[0131] wherein “Antibody-” represents the position at which the anti-TROP2 antibody is connected. In one embodiment, the anti-TROP2 ADC to which the scoring is directed is datopotamab deruxtecan (DS-1062). Thus, in various embodiments, the diagnostic biomarker also targets the TROP2 protein.
[0139]
[0132] In step 12, image analysis is performed on the digital image to generate image objects of cancer cells, cell membranes and cytoplasm objects. A pretrained convolutional neural network processes a digital image of tissue of the cancer patient that has been stained with the diagnostic antibody linked to the dye, such as 3,3’- Diaminobenzidine (DAB). The staining intensity of the dye in the membrane of a cancer cell is determined based on the mean staining intensity of the dye of all pixels associated with the corresponding segmented membrane object. Moreover, the staining intensity of the dye in a single pixel is computed based on the red, green and blue color components of the pixel. The result of the image analysis processing provides, for each pixel in the digital image, the probability that the pixel belongs to a cell membrane and the probability that the pixel belongs to a cell cytoplasm. Suitable methods for generating these image objects are described in more detail in WO 2023 / 175483 Al.
[0140]
[0133] In step 13, the mean optical density (OD) of staining of the dye in the cell membrane is determined for each cancer cell.
[0141]
[0134] In step 14, the mean optical density (OD) of staining of the dye in the TROP2-403-PCT01-NP cytoplasm is determined for each cancer cell.
[0142]
[0135] In steps 13 and 14, where DAB is used as the dye, the amount of DAB can be determined by the staining intensity based on the mean (average) optical density of the brown diaminobenzidine (DAB) signal in all of the pixels of the membrane, or in all of the pixels of the cytoplasm, respectively.
[0143]
[0136] In step 15, the normalized membrane optical density for each cancer cell in the digital image is computed. The normalized membrane optical density equals the mean optical density of staining of the membrane divided by the sum of the mean optical density of staining of the membrane plus the mean optical density of staining of the cytoplasm.
[0144]
[0137] In step 16, a predicted response score is generated for the tissue sample based on a percentage quartile of cancer cells in the digital image that have normalized membrane optical density values equal to or less than a normalized membrane optical density threshold, or greater than the normalized membrane optical density threshold. The predicted response score is positive (in other words, the tissue sample is normalized membrane positive) if the percentage quartile of cancer cells in the tissue sample that are normalized membrane positive is equal to or less than the normalized membrane optical density threshold. The predicted response score is negative (in other words, the tissue sample is normalized membrane negative) if the percentage quartile of cancer cells in the tissue sample that are normalized membrane positive is greater than the normalized membrane optical density threshold.
[0145]
[0138] In step 17, the cancer patient is identified as one who will likely benefit from administration of the anti-TROP2 ADC if the predicted response score is positive (in other words, if the tissue sample is normalized membrane positive).
[0146]

[0229] VIII. Examples of prediction and scoring method.
[0234]
[0230] Example 1
[0235]
[0231] A biomarker evaluable population (BEP) of 352 patients (i.e. those with available tissue samples for QCS determination) with non-small cell lung cancer were studied. The baseline characteristics of these patients are provided in the table below, where there were no significant differences in baseline characteristics between the randomized and biomarker-evaluable populations: TROP2-403-PCT01-NP
[0236] (NMR = normalized membrane ratio; ECOG PS = Eastern Cooperative Oncology Group Performance Status; NSQ = non-squamous; SQ = squamous; AGA = actionable genomic alterations; non-AGA = non-actionable genomic alterations;apatients who are no longer symptomatic and who require no treatment with corticosteroids and anticonvulsants and have recovered from acute toxic effects of radiation)
[0237]
[0232] In addition, the safety characteristics of treatment-related adverse events are provided in the table below, where overall / Grade 3+ adverse event rates were similar regardless of TROP2 QCS-NMR status:
[0238] (AESI = adverse event of special interest; ILD = interstitial lung disease; * Biomarker-evaluable population in safety analysis excludes patients who were randomized but did not receive treatment;bincludes events that were adjudicated as ILD and related to use of Dato-DXd or docetaxel (includes cases of potential ILD / pneumonitis based on MedDRA v26.0 for the narrow ILD SMQ, selected terms from the broad ILD SMQ, and PTs of respiratory failure and acute respiratory failure) TROP2-403-PCT01-NP
[0239]
[0233] Analysis of these treatment data is shown in FIGs 4-11.
[0240]
[0234] In FIG. 4, the Kaplan-Meier curves for progression-free survival and overall survival were plotted for the full intention-to-treat cohort (N=604) for nonsmall cell lung cancer, which includes patients who are biomarker evaluable (i.e. have available tissue samples for QCS determination) (N=352) and the remaining patients who are not biomarker evaluable (N=252). These data are further stratified to the type of treatment provided: either datopotamab deruxtecan (Dato-DXd) or docetaxel. Irrespective of whichever treatment was provided, the Kaplan-Meier curves for the respective BEP and ITT groups are similar to each other, indicating that the BEP cohort is a representative sample of the full ITT cohort.
[0241]
[0235] In FIG. 5, the BEP cohort was analyzed and the Kaplan-Meier curves for progression-free survival and overall survival were plotted. The data indicates that for the biomarker positive arm (BM+) treated with Dato-DXd, there is a significant increase in progression-free survival and overall survival as compared to the biomarker negative arm (BM-), where the biomarker measured is normalized membrane optical density (nmOD) at a percentage quantile of Q75 with an nmOD threshold of <0.5585. In contrast, when the same analysis is conducted on the patients treated with docetaxel, there is no statistically significant difference between the BM+ arm compared to the BM- arm. These data therefore indicate that ADC treatment outcomes of non-small cell lung cancer can be greatly improved by checking for the presence of this biomarker.
[0242]
[0236] In FIG. 6, the Kaplan-Meier curves for progression-free survival and overall survival were plotted for the cohort with non-squamous non-small lung cancer without actionable genomic alterations (N=370), which includes patients who are biomarker evaluable (i.e. have available tissue samples for QCS determination) (N=221) and the remaining patients who are not biomarker evaluable (N=149). Again, these data are further stratified to the type of treatment provided: either datopotamab deruxtecan (Dato-DXd) or docetaxel. Similar to FIG. 4, irrespective of whichever treatment was provided, the Kaplan-Meier curves for the respective BEP and ITT groups are similar to each other, indicating that the BEP cohort is a representative sample of the full ITT cohort. TROP2-403-PCT01-NP
[0243]
[0237] In FIG. 7, the BEP cohort for non-squamous non-small lung cancer without actionable genomic alterations was analyzed and the Kaplan-Meier curves for progression-free survival and overall survival were plotted. Similar to FIG. 5, the data indicates that for the BM+ arm treated with Dato-DXd, there is a significant increase in progression-free survival and overall survival as compared to the BM- arm. These data therefore indicate that ADC treatment outcomes of non-small cell lung cancer, in particular non-squamous non-small cell lung cancer without actionable genomic alterations, can be greatly improved by checking for the presence of this biomarker.
[0244]
[0238] In FIG. 8, the Kaplan-Meier curves for progression-free survival and overall survival were plotted for the cohort with non-squamous non-small lung cancer with actionable genomic alterations (N=98), which includes patients who are biomarker evaluable (i.e. have available tissue samples for QCS determination) (N=51) and the remaining patients who are not biomarker evaluable (N=47).
[0245]
[0239] In FIG. 9, the BEP cohort for non-squamous non-small lung cancer with actionable genomic alterations was analyzed and the Kaplan-Meier curves for progression-free survival and overall survival were plotted. These data seem to indicate a potential benefit in this patient population when comparing the BM+ arm treated with Dato-DXd with the BM- arm, particularly in the progression-free survival curve.
[0246]
[0240] In FIG. 10, the Kaplan-Meier curves for progression-free survival and overall survival were plotted for the cohort with squamous non-small lung cancer (N=136), which includes patients who are biomarker evaluable (i.e. have available tissue samples for QCS determination) (N=80) and the remaining patients who are not biomarker evaluable (N=56).
[0247]
[0241] In FIG. 11, the BEP cohort for squamous non-small lung cancer was analyzed and the Kaplan-Meier curves for progression-free survival and overall survival were plotted. These data seem to indicate a potential benefit in this patient population when comparing the BM+ arm treated with Dato-DXd with the BM- arm, particularly in the progression-free survival curve.
[0248]
[0242] An analysis of potentially using different percentage quantiles and different nmOD thresholds was also conducted. These data are presented in FIGs. 2 and 3. TROP2-403-PCT01-NP
[0249]
[0243] In FIG. 2, different nmOD values can be used for different percentage quantiles. For percentage quantiles of about 50% (Q50) to about 95% (Q95), typical values for the nmOD threshold can be in a range of about 0.53 to about 0.59. As shown in FIG. 2, when the percentage quantile is about 70% (Q70) to about 80% (Q80), suitable values for the nmOD threshold can be in a range of about 0.55 to about 0.57.
[0250]
[0244] In FIG. 3, different percentage quantiles can be used. Percentage quantiles of about 50% (Q50) to about 95% (Q95) generate statistically significant results where the p-value is typically <0.01 in nmOD thresholds of interest. More statistically significant results can be obtained as the percentage quantile is narrowed closer to about 75% (Q75), such as about 65% (Q65) to about 90% (Q90), or about 70% (Q70) to about 80% (Q80). In particular, percentage quantiles of about 70% (Q70) to about 80% (Q80) generate statistically significant results where the p-value is typically <0.001 in nmOD thresholds of interest.
[0251]
[0245] Example 2
[0252]
[0246] A further biomarker evaluable population (BEP) of 38 patients (i.e. those with available tissue samples for QCS determination) with non-small cell lung cancer were studied. The demographic and baseline characteristics of these patients are provided in the table below, where these were broadly comparable to those of the total patient population: TROP2-403-PCT01-NP
[0253] (AJCC, American Joint Committee on Cancer; ECOG PS, Eastern Cooperative Oncology Group performance status; NMR, normalized membrane ratio; TROP2, trophoblast cell surface antigen 2; QCS, quantitative continuous scoring)
[0254]
[0247] In total, 52.6% (N=20 / 38) were TROP2 QCS-NMR positive. Of the 38 patients for whom QCS was evaluable, 21 were non-squamous and 17 were squamous. TROP2 QCS-NMR-positive tumors were numerically higher in patients with non-squamous (76.2%) vs. squamous histology (23.5%), as shown in the table below:
[0255] (NMR, normalized membrane ratio; QCS, quantitative continuous scoring; TROP2, trophoblast cell surface antigen 2)
[0256]
[0248] In addition, the safety characteristics of treatment-related adverse events are provided in the table below, where the safety profile by TROP2 QCS-NMR status was generally comparable:
[0257] (AESI, adverse event of special interest; ILD, interstitial lung disease; NMR, normalized membrane ratio; QCS, quantitative continuous scoring; TRAE, treatment-related adverse event; TROP2, trophoblast cell surface antigen 2; *AESIs are grouped terms using preferred terms selected from relevant standardized MedDRA query, MedDRA V26.0; Adjudicated ILD, CTCAE grade and relationship with study drug were assessed by the adjudication committee.) TROP2-403-PCT01-NP
[0258]
[0249] The response rate by TROP2 QCS-NMR status is provided in the table below, where ORR was numerically higher for patients with TROP2 QCS-NMR- positive tumors vs. TROP2 QCS-NMR-negative tumors:
[0259] (NMR, normalized membrane ratio; ORR, objective response rate; QCS, quantitative continuous score;
[0260] TROP2, trophoblast cell surface antigen 2)
[0261]
[0250] Analysis of the treatment data is also shown in FIG. 15.
[0262]
[0251] In FIG. 15, median progression-free survival was longer for patients with TROP2 QCS-NMR-positive tumors than patients with TROP2 QCS-NMR- negative tumors. These data reinforce the conclusion that ADC treatment outcomes of non-small cell lung cancer can be greatly improved by checking for the presence of this biomarker.
