Description

[Technical field]

[0001] cross reference This application claims the benefit of U.S. Provisional Patent Application No. 63 / 184,697, filed May 5, 2021, and U.S. Provisional Patent Application No. 63 / 320,991, filed March 17, 2022, the contents of which are incorporated by reference in their entireties herein.

[0002] The present disclosure relates to combinations comprising SHP2 and EGFR tyrosine kinase inhibitors, and the use of such combinations in the treatment of cancer. [Background technology]

[0003] Cancer is a leading cause of morbidity and mortality worldwide. Although the standard of care for many different cancer types has improved significantly over the years, the current standard of care still does not meet the need for effective therapies to improve cancer treatment. SH2-containing protein tyrosine phosphatase 2 (SHP2) belongs to the protein tyrosine phosphatase family, which is involved in regulating cell proliferation, survival, differentiation, migration and apoptosis. In recent years, SHP2 has been shown to play an important role in tumor inhibition, and the role of SHP2 in tumors in particular is becoming increasingly evident. Thus, activation of SHP2 represents a viable antitumor strategy.

[0004] In the protein tyrosine phosphatase superfamily, SHP2 is the first identified true proto-oncogene and plays a key role in various signaling pathways such as metabolism, differentiation, proliferation, migration and survival. SHP2 can regulate Ras mitogen-activated protein kinase, Janus kinase-signal transduction and activator of transcription (JAK-STAT) or phosphoinositide 3-kinase-AKT and nuclear factor kappa B (NF-kappa B) as well as other signaling pathways. SHP2 is also a master regulator of programmed cell death protein-1 (PD-1) and B and T lymphocyte attenuator (BTLA) immune checkpoint signaling pathways, which may be related to tumor immune suppression. Moreover, SHP2 mutations occur rarely in tumors.

[0005] The epidermal growth factor receptor (EGFR) is a transmembrane protein that is a receptor for members of the epidermal growth factor family (EGF family) of extracellular protein ligands. In many cancer types, mutations that affect the expression or activity of EGFR lead to cancer. Many drug treatments have been developed that target EGFR. One method involves using small molecules to inhibit the EGFR tyrosine kinase (TK), which is located on the cytoplasmic side of the receptor. Without kinase activity, EGFR cannot activate itself, which is a prerequisite for binding downstream adaptor proteins. Clearly, by stopping the signaling cascade in cells that depend on this pathway for growth, tumor growth and migration are reduced. However, many patients exhibit resistance. The two main sources of resistance are the T790M mutation and the MET oncogene. Thus, a significant number of tumors are either resistant or refractory. Thus, new therapies, including, for example, combination therapies for the treatment of cancer, are needed. Combinations and methods of treating cancer are provided herein. Summary of the Invention

[0074] In some embodiments, the compound as described herein may be provided in an amount that is synergistic with the amount of the EGFR TK inhibitor. The term synergistic refers to a combination as described herein (e.g., a compound of formula (Ia) and an EGFR TK inhibitor (including co-administration with another active agent, such as an anti-cancer agent as described herein)) or a combination of regimens that is more effective than the additive effect of each individual treatment or regimen.

[0075] The synergistic effect of the combinations described herein may allow the use of lower dosages of one or more components of the combination (e.g., a compound of formula (Ia) or an EGFR TK inhibitor). The synergistic effect may allow for less frequent administration of at least one of the administered therapeutic agents (e.g., a compound of formula (Ia) or an EGFR TK inhibitor) to a subject having a disease, disorder, or condition described herein. Such lower dosages and reduced frequency of administration may reduce the toxicity associated with the administration of at least one of the therapeutic agents to a subject without reducing the efficacy of the treatment. The synergistic effect avoids or reduces the harmful and undesirable side effects associated with the use of any treatment.

[0076] Further forms of the compound In some embodiments, the compounds disclosed herein have one or more stereocenters, and each stereocenter exists independently in either the R or S configuration. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms, and appropriate mixtures thereof. The compounds and methods provided herein include all cis-, trans-, syn-, anti-, entgegen (E) and zusammen (Z) isomers, and appropriate mixtures thereof. In certain embodiments, the compounds described herein are prepared as individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds / salts, separating the diastereomers, and recovering the optically pure enantiomers. In some embodiments, the resolution of the enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein. In another embodiment, the diastereomers are separated by separation / resolution techniques based on differences in solubility. In other embodiments, separation of stereoisomers is accomplished by chromatography, or by formation of diastereomeric salts and separation by recrystallization, or chromatography, or any combination thereof. Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and Resolutions," John Wiley and Sons, Inc., 1981. In one aspect, stereoisomers are obtained by stereoselective synthesis.

[0077] In some embodiments, the compounds described herein are prepared as prodrugs. A "prodrug" refers to an agent that is converted to the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be administered more easily than the parent drug. For example, a prodrug may be bioavailable for oral administration, whereas the parent drug is not. A prodrug may also have improved solubility in pharmaceutical compositions compared to the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. A non-limiting example of a prodrug is a compound described herein that is administered as an ester ("prodrug") to facilitate crossing cell membranes where water solubility is disadvantageous for mobility, but is metabolically hydrolyzed to the active entity, a carboxylic acid, once inside a cell where water solubility is beneficial. A further example of a prodrug may be a short peptide (polyamino acid) bonded to an acid group, which is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, the prodrug is chemically converted to the biologically, pharma- ceutical, or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharma- ceutical or therapeutically active form of the compound.

[0078] In one aspect, prodrugs are designed to alter the metabolic stability or transport properties of a drug, mask side effects or toxicity, improve the taste of the drug, or change other properties or characteristics of the drug. Once a pharmacokinetic (PK), pharmacodynamic (PD) process and drug metabolism in vivo are known, it is possible to design a prodrug of that compound.

[0178] When used in connection with an antibody or functional fragment thereof (e.g., "one or more humanized antibodies"), the term "human" refers to an antibody or functional fragment having a human variable region or a portion thereof that corresponds to a human germline immunoglobulin sequence. Such human germline immunoglobulin sequences are described in Kabat et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, USDepartment of Health and Human Services, NIH Publication No. 91-3242. In certain embodiments, the human antibody is an antibody having an amino acid sequence that corresponds to the amino acid sequence of an antibody produced in a human and / or an antibody made using any of the techniques for making human antibodies disclosed herein. Human antibodies can be produced using a variety of techniques known in the art, including phage display libraries. Hoogenboom and Winter, Mol. Biol., 227:381 (1991); Marks et al., Mol. Biol., 222:581 (1991). Methods described in Cole et al., Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, p. 77 (1985); Boemer et al., Immunol., 147(1):86-95 (1991) can also be used to prepare human monoclonal antibodies. See also van Dijk and van de Winkel, Curr. Opin. Pharmacol., 2:368-74 (2001). Human antibodies can be prepared by administering antigen to transgenic animals (e.g., immunized xenoMouse) that have been modified to produce such antibodies in response to antigenic change, but whose endogenous gene loci have been invalidated (see, e.g., U.S. Patent Nos. 6,075,181 and 6,150,584 for xenoMouse technology). See also, e.g., Li et al., Proc. Natl. Acad. Sci. USA, 103:3557-3562 (2006) regarding human antibodies produced via human B cell hybridoma technology.

[0179] "Humanized antibody" refers to an antibody made by a non-human cell with a variable region or a variable region and a constant region that have been modified to closely resemble an antibody made by a human cell, for example, by modifying a non-human antibody amino acid sequence to incorporate amino acids found in human germline immunoglobulin sequences. The humanized antibody of the present invention can include, for example, amino acid residues in the CDRs that are not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). Humanized antibodies can also include antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human framework sequences.

[0180] Humanized forms of non-human (e.g., murine) antibodies are antibodies that have minimal sequence derived from non-human immunoglobulin. In some embodiments, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region of the recipient are replaced by residues from a hypervariable region of a non-human species (donor antibody) such as mouse, rat, rabbit or non-human primate having the desired specificity, affinity, and / or capacity. In some instances, framework ("FR") residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, humanized antibodies may comprise residues that are not found in the recipient antibody or the donor antibody. These modifications may be made to further improve antibody performance, such as binding affinity. Generally, a humanized antibody will comprise substantially all of at least one, and typically two, variable domains in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin sequence, and all or substantially all of the FR regions are those of a human immunoglobulin sequence, although the FR regions may contain one or more individual FR residue substitutions which improve antibody performance, such as binding affinity, isomerization, immunogenicity, etc. The number of amino acid substitutions in these FRs will typically be no more than six in the H chain and no more than three in the L chain. The humanized antibody may also comprise at least a portion of an immunoglobulin constant region (Fc), which may optionally be a human immunoglobulin. Exemplary methods and humanized antibodies include those described in Jones et al. Nature 321:522-525 (1986); Riechmann et al. Nature 332:323-329 (1988), and Presta, Curr. Op. Struct. Biol. 2:593-596 (1992); Vaswani and Hamilton, Ann. Allergy. Asthma & Immunol. 1:105-115 (1998); Harris, Biochem. Soc. Transactions 23:1035-1038 (1995); Burle and Gross, Curr. Op. Biotech. 5:428-433 (1994), and U.S. Patent Nos. 6,982,321 and 7,087,409.

[0181] The term "functional fragment" when used in reference to an antibody refers to a portion of an antibody, including a heavy or light chain polypeptide, that retains some or all of the binding activity of the antibody from which the fragment is derived. Such functional fragments can include, for example, Fd, Fv, Fab, F(ab'), F(ab)2, F(ab')2, single chain Fv (ScFv), diabodies, triabodies, tetrabodies, and minibodies. Other functional fragments include, for example, heavy or light chain polypeptides, variable region polypeptides, or CDR polypeptides or portions thereof, so long as such functional fragments retain binding activity. Such antibody-binding fragments can be found, for example, in Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, New York (1989); Myers (ed.), Molec. Biology and Biotechnology: A Comprehensive Desk Reference, New York: VCH Publisher, Inc.; Huston et al., Cell Biophysics, 22:189-224 (1993); Pluckthun and Skerra, Meth. Enzymol., 178:497-515 (1989) and Day, ED, Advanced Immunochemistry, Second Ed., Wiley-Liss, Inc., New York, NY (1990). Antibody Engineering, Second Edition, Oxford University Press, 1995.

[0182] The term "heavy chain" when used in reference to an antibody refers to a polypeptide chain of about 50-70 kDa, with an amino terminal portion containing a variable region of about 120-130 or more amino acids, and a carboxy terminal portion containing a constant region. The constant region can be one of five different types, designated alpha (a), delta (δ), epsilon (ε), gamma (γ) and mu (μ), based on the amino acid sequence of the heavy chain constant region. Different heavy chains vary in size; α, δ and γ contain approximately 450 amino acids, while μ and ε contain approximately 550 amino acids. When combined with light chains, these different types of heavy chains give rise to the five well-known classes of antibodies, IgA, IgD, IgE, IgG and IgM (four subclasses of IgG: IgG1, IgG2, IgG3 and IgG4), respectively. The heavy chain can be a human heavy chain.

[0183] The term "light chain" when used in reference to an antibody refers to a polypeptide chain of about 25 kDa, the amino terminal portion containing a variable region of about 100 to about 110 or more amino acids, and the carboxy terminal portion containing the constant region. The approximate length of a light chain is 211 to 217 amino acids. Based on the amino acid sequence of the constant domain, two different types exist, designated lambda (λ) and kappa (κ). Light chain amino acid sequences are well known in the art. The light chain may be a human light chain.

[0184] The term "variable domain" or "variable region" refers to a portion of an antibody light or heavy chain, generally located at the amino terminus of the light or heavy chain, having a length of about 120-130 amino acids in the heavy chain and about 100-110 amino acids in the light chain, which is used in the binding and specificity of each particular antibody for its particular antigen. Variable domains can vary extensively in sequence between different antibodies. The sequence variability is concentrated in the CDRs, while the less variable portions of the variable domains are called framework regions (FRs). The CDRs of the light and heavy chains are primarily responsible for the interaction of the antibody with the antigen. The numbering of amino acid positions used herein is based on Kabat et al. (1991) Sequences of proteins of immunological interest (USDepartment of Health and Human Services, Washington, DC) 5 th The variable regions may be human variable regions.

[0185] CDR refers to one of the three hypervariable regions (H1, H2 or H3) in the non-framework region of the immunoglobulin (Ig or antibody) VH β-sheet framework, or the three hypervariable regions (L1, L2 or L3) in the non-framework region of the antibody VL β-sheet framework. Thus, CDR is a variable region sequence distributed in the framework region sequence. CDR regions are well known to those skilled in the art, and are defined by Kabat, for example, as the most hypervariable region in the antibody variable (V) domain (Kabat et al., Biol. Chem. 252:6609-6616 (1977); Kabat, Adv. Prot. Chem. 32:1-75 (1978)). CDR region sequences have also been structurally defined by Chothia as those residues that are not part of the conserved β-sheet framework and therefore can adapt to different conformations (Chothia and Lesk, Mol. Biol. 196:901-917 (1987)). Both terms are recognized in the art. The positions of CDRs within canonical antibody variable domains have been determined by comparing multiple structures (Al-Lazikani et al., Mol. Biol. 273:927-948 (1997); Morea et al., Methods 20:267-279 (2000)). Because the number of residues within the hypervariable regions differs in various antibodies, additional residues relative to the canonical positions are conventionally numbered a, b, c, etc. next to the residue number in the standard variable domain numbering scheme (Al-Lazikani et al., supra (1997)). Such nomenclature is likewise within the skill of the art. EXAMPLES

[0186] It will be understood that the following examples are intended to illustrate the present disclosure, but are not intended to limit the present disclosure.Various other examples and modifications of the above description and examples will be apparent to those skilled in the art after reading this disclosure without departing from the spirit and scope of the present disclosure, and all such examples or modifications are intended to be included within the scope of the appended claims.All publications and patents referred to in this specification are incorporated herein by reference in their entirety.

[0187] Example 1: Synthesis and in vitro activity of compounds of formula (Ia) Compounds of formula (I), (Ia) and (II) can be synthesized by the methods provided in PCT / CN2020 / 07791, which is incorporated herein by reference in its entirety. In some embodiments, synthesis of the compounds described herein is accomplished using means described in the chemical literature, using methods described herein, or by a combination thereof.

[0188] Cell lines and maintenance: Both cell lines (HCC827-ER1 and NCI-H1975) used for in vitro and in vivo studies were provided by Crown Biosciences cell bank. HCC827-ER1 cells were maintained in RPMI medium supplemented with 10% heat-inactivated fetal bovine serum + 42 μM erlotinib at 37°C in an atmosphere of 5% CO2 in air. NCI-H1975 cells were maintained in RPMI medium supplemented with 10% heat-inactivated fetal bovine serum + 100ug / mL hygromyosin at 37°C in an atmosphere of 5% CO2 in air. Tumor cells were routinely subcultured twice a week. Exponentially growing cells were used for in vitro cell potency and in vivo efficacy studies.

[0189] Cell viability assay: For cytotoxicity assay, cells were seeded in 96-well plates and the seeding density was determined based on the Crown Biosciences Cell line Database. Cells were seeded at 2000 cells / well. 24 hours after seeding, cells were treated with inhibitors at the indicated compound concentrations. On day 5, cells were lysed with CellTiter-Glo® Luminescent Cell Viability Assay reagent (Promega) and luminescence was read using an EnVision Multi-plate reader. To calculate IC50, a nonlinear regression model with a sigmoidal dose response was used to generate a dose-response curve. IC50 was automatically generated by GraphPad Prism 8.0. The formula for viability is shown below. Viability (%) = ((LumTest product - LumMedium control) / (LumNone treatment - LumMedium control)) x 100

[0190] The in vitro test results are shown in the log-linear graphs of FIG. 1A and FIG. 1B and summarized in Table 1.

[0191] [Table 1]

[0192] Example 2: Animal Models and In Vivo Treatments Procedures involving the care and use of animals in this study were reviewed and approved by the Institutional Animal Care and Use Committee (IACUC) of Crown Biosciences prior to implementation. Throughout the study, the care and use of animals was performed in accordance with the International Association for the Assessment and Accreditation of Laboratory Animal Care (AAALAC) regulations. Animals (6–8 weeks) were obtained from Shanghai Lingchang Biotechnology Co., Ltd (Shanghai, China) and allowed to acclimate prior to tumor cell inoculation.

[0193] GH21005 (compound of formula (Ia)) was supplied by Huyabio International, LLC. RMC-4550 was purchased from MCE, China. Osimertinib was purchased from Selleck, China.

[0194] All cell lines were maintained in culture and cells in the exponential growth phase were harvested and quantified by cell counter before tumor inoculation. HCC827-ER1 tumor cells (5 × 10 ) in 0.1 ml PBS mixed with Matrigel (1:1) were inoculated into female Balb / C nude animals. 7 ) had an average tumor size of approximately 325 mm at the start of treatment. 3 It was.

[0195] The date of randomization and treatment initiation was designated as day 0. Tumor volumes were measured twice weekly in two dimensions using calipers and volumes were expressed in mm using the formula: V = (L × W × W) / 2. 3 where V is the tumor volume, L is the tumor length (longest tumor dimension), and W is the tumor width (longest tumor dimension perpendicular to L). The dosing volume was 10 mL / kg / day. GH21005 was dissolved in HP-β-CD and dissolved in 200 ml of 50 mM sodium citrate (pH=4.2). Anti-PD-1 and rat IgG2a were diluted in PBS. RMC-4550 was diluted in 1% Captisol® in 50 mM sodium citrate (pH=5.0), and 0.5% dosing solution of osimertinib was diluted in 2% DMSO / 30% PEG300.

[0196] At termination, tumors were harvested 2 hours after the last dose. A portion of the tumor was minced and immediately flash frozen for protein isolation. Another portion of the tumor was fixed in 10% neutral buffered formalin and then processed into paraffin blocks.

[0197] The results of these experiments are shown in Figure 2A-B (HCC827-ER1). The results show that treatment with the compound of formula (Ia) alone did not result in a reduction in tumor volume (see the red line in Figure 2A). Furthermore, treatment with osimertinib alone resulted in a slight and temporary reduction in tumor volume, followed by growth in tumor volume before the end of the treatment regimen (see the green line in Figure 2A). However, treatment with the compound of formula (Ia) in combination with osimertinib resulted in a significant and sustained reduction in tumor volume (see the orange line in Figure 2A). This reduction in tumor volume observed in the treatment group receiving the combination of the compound of formula (Ia) with osimertinib disappeared after the cessation of the treatment program. Taken together, these results demonstrate a synergistic effect between the compound of formula (Ia) and osimertinib. FIG. 2A also shows the same synergistic relationship between RMC-4550 and osimertinib, demonstrating that compounds of formula (I) and formula (II) exhibit synergistic effects with osimertinib when administered to tumors.

[0198] Example 3: Immunohistochemistry Freshly harvested tumor tissue was placed in 10% NBF and fixed for 24 hours at room temperature. Tumor tissue was trimmed and rinsed with running water. Specimens were transferred to a vacuum tissue processor (Leica HistoCore PEARL) for dehydration and then embedded into FFPE blocks using a tissue embedding center (Leica HistoCore Arcadia Hot and Cold). FFPE blocks were sectioned on a manual rotary microtome (HistoCore MULTICUT, Leica), 4 μm thick per section. Reagents for IHC and antigen retrieval including Bond™ Epitope Retrieval Solution 1 (Bond ER1), Bond™ Epitope Retrieval Solution 2 (Bond ER2), Bond™ Dewax Solution, and Bond™ Wash. Primary antibodies phospho-p44 / 42 MAPK (Erk1 / 2) (Thr202 / Tyr204), CST4370 and 44 / 42 MAPK (Erk1 / 2) (137F5) CST4695 were used at 1:400 and 1:1000 dilutions, respectively. Anti-rabbit poly-HRP-IgG (<25 μg / mL) containing 10% (v / v) animal serum in Tris-buffered saline / 0.09% ProClin™ 950 (ready-to-use) Leica DS9800 was used for secondary detection.

[0199] All stained sections were scanned at 40x magnification with a NanoZoomer-HT 2.0 Image system to generate high-resolution photographs of all sections for further analysis. All images were analyzed on the HALO™ platform.

[0200] IHC scoring method: The entire slide images were analyzed, excluding necrotic and stromal areas. The intensity of specific staining was scored into four levels: 0 (negative), 1+ (weak staining), 2+ (moderate staining), and 3+ (strong staining). The percentage of tumor cells at different intensity levels was evaluated with H score. H-Score = (% at 0) x 0 + (% at 1) x 1 + (% at 2) x 2 + (% at 3) x 3 (H-Score ranges from 0 to 300).

[0201] The ratio of pERK to ERK is shown in the graph in Figure 3. See also Figure 4 and Figure 10A-D for representative images.

[0202] Example 4: Immunoblot analysis

[0203] Tumors were harvested at each time point after administration and flash frozen in liquid nitrogen. Tissues were ground in liquid nitrogen using a mortar and pestle and weighed. An amount of RIPA buffer containing phosphatase and protease inhibitors was added at three times the weight, and samples were inverted and placed on ice for 30 minutes. Cell lysates were obtained by centrifugation at 14,000g for 15 minutes at 4°C, and the supernatant was transferred to a new tube. Protein was quantified using the Pierce BCA Protein Assay Kit. 50 μg of protein was loaded per well. Gels were transferred to pre-activated PVDF, and primary and secondary antibodies were diluted in TBST containing 5% milk powder. Target proteins were detected with a Tanon 5200 chemiluminescence imaging system using the ECL method. The ratio of pERK / ERK is measured to quantify relative expression. See Figure 5, Figure 6, and Figure 7. DUSP6 / β-actin expression levels are shown in Figure 8 and Figure 9. Primary antibodies: DUSP6, Abcam ab76310, β-actin CST 3700S, p-ERK CST 4370s, ERK CST 4695s.
