[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority under 35 USC § 119(e) to U.S. Provisional Application No. 63 / 191,631, filed May 21, 2021, the entire contents of which are incorporated herein by reference for all purposes. [Background technology]
[0002] AXL is a receptor tyrosine kinase (RTK) belonging to the TAM family. AXL regulates important processes such as cell proliferation, migration, aggregation, and apoptosis. AXL can be activated by various mechanisms, including ligand-dependent and ligand-independent mechanisms. Once activated, AXL participates in various signaling pathways, including the RAS-RAF-MEK-ERK pathway, which leads to cancer cell proliferation, and the PI3K / AKT pathway, which involves several pro-survival proteins.
[0003] AXL has been shown to be overexpressed in a variety of malignancies, and in the cancer setting, AXL overexpression is associated with poor patient survival and resistance mechanisms (both targeted and untargeted).
[0004] In light of research linking AXL inhibition to diseases such as cancer, there is a need in the art for novel AXL inhibitors. The present disclosure addresses this need by providing additional advantages not found in conventional AXL inhibitors. Summary of the Invention

Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, monohydrogencarbonic acid, phosphoric acid, monohydrogenphosphate, dihydrogenphosphate, sulfuric acid, monohydrogensulfuric acid, hydroiodic acid, or phosphorous acid, as well as those derived from relatively non-toxic organic acids such as acetic acid, propionic acid, isobutyric acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-tolylsulfonic acid, citric acid, tartaric acid, methanesulfonic acid, and the like.Also included are salts of amino acids such as arginate, and salts of organic acids such as glucuronic acid or galacturonic acid (see, e.g., Berge, SM, et al, "Pharmaceutical Salts," Journal of Pharmaceutical Science, 1977, 66, 1-19). Certain compounds of the present disclosure contain both basic and acid functional groups that allow the compounds to be converted into either base or acid addition salts.
[0026] The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound may differ from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for purposes of this disclosure.
[0027] In addition to salt forms, the present disclosure provides compounds in prodrug form. Prodrugs of the compounds described herein are compounds that easily undergo chemical changes under physiological conditions to provide the compounds of the present disclosure. In addition, prodrugs can be converted to the compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be gradually converted to the compounds of the present disclosure when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent.
[0028] Certain compounds of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. Certain compounds of the present disclosure may exist in multiple crystalline or amorphous forms.
[0029] Certain compounds of the present disclosure possess asymmetric carbon atoms (optical centers) or double bonds. All racemic mixtures, diastereomers, geometric isomers, positional isomers, and individual isomers (e.g., separated enantiomers) are intended to be included within the scope of the present disclosure. When stereochemistry is described, it refers to a compound in which the described isomer is present and is substantially free of other isomer(s). "Substantially free" of other isomer(s) refers to a ratio of at least 80 / 20, more preferably 90 / 10, or 95 / 5 or greater, of the described isomer to the other isomer(s). In some embodiments, one of the isomers is present in an amount of at least 99%.
[0030] The compounds of the present disclosure may contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. Unnatural proportions of an isotope may be defined as a range from the amount found in nature to the amount that constitutes 100% of the atom in question. For example, a compound may contain, for example, tritium ( 3 H), iodine-125( 125 I), or carbon-14 ( 14 Radioactive isotopes such as C, or deuterium ( 2 H), or carbon-13 ( 13 Non-radioactive isotopes such as C) may be incorporated. Such isotopic variations may provide additional utilities to those described elsewhere in this application. For example, but not limited to, isotopic variants of the disclosed compounds may find additional uses as diagnostic and / or imaging reagents or cytotoxic / radiotoxic therapeutic agents. In addition, isotopic variants of the disclosed compounds may have modified pharmacokinetic and pharmacodynamic properties. All isotopic variants of the disclosed compounds, whether radioactive or not, are intended to be included within the scope of this disclosure.
[0031] The terms "patient" and "subject" are used interchangeably to refer to a human or non-human animal (eg, a mammal).
[0032] The terms "treat," "treating," "treatment," and the like refer to an action initiated after a disease, disorder, or condition, or a symptom thereof, has been diagnosed, recognized, or the like (such as administering an inhibitor of AXL, or a pharmaceutical composition comprising same), which eliminates, reduces, suppresses, alleviates, or ameliorates, temporarily or permanently, at least one of the underlying causes of the disease, disorder, or condition afflicting the subject, or at least one of the symptoms associated with the disease, disorder, or condition afflicting the subject. Thus, treatment includes inhibiting active disease (e.g., preventing the onset or further development of the disease, disorder, or condition, or clinical symptoms associated therewith).
[0033] As used herein, the term "in need of treatment" refers to a determination by a physician or other caregiver that a subject is in need of or would benefit from treatment. This determination is made based on a variety of factors within the physician's or caregiver's expertise.
[0034] The terms "prevent," "preventing," "prevention," and the like refer to initiating a course of action (e.g., administering an AXL inhibitor or a pharmaceutical composition containing the inhibitor) (e.g., before a disease, disorder, condition, or symptoms thereof are observed) to temporarily or permanently prevent, suppress, inhibit, or reduce a subject's risk of developing a disease, disorder, condition, or the like (e.g., as determined by the absence of clinical symptoms), or, generally, to delay the onset of a particular disease, disorder, or condition in a subject predisposed to having it. In certain instances, these terms also refer to slowing the progression of a disease, disorder, or condition, or inhibiting progression to an adverse or unwanted condition.
[0035] As used herein, the term "in need of prevention" refers to a determination by a physician or other caregiver that a subject needs or would benefit from preventative care. This determination is made based on a variety of factors within the physician's or caregiver's expertise.
[0036] The phrase "therapeutically effective amount" refers to an amount of an agent (e.g., a compound according to the present disclosure) administered to a subject, either alone or as part of a pharmaceutical composition, and either in a single dose or a series of doses, that is capable of producing any detectable positive effect on any symptom, condition, or characteristic of a disease, disorder, or condition when administered to a subject. A therapeutically effective amount can be determined by measuring the relevant physiological effect and can be adjusted in conjunction with dosing regimens, diagnostic assays for the subject's condition, and the like. For example, measuring serum levels of an AXL inhibitor (or, for example, a metabolic product thereof) at a particular time after administration can indicate whether a therapeutically effective amount has been used. Additionally, an effective amount of an AXL inhibitor of the present disclosure can be an amount that, when administered one or more times to a subject, produces a desired result compared to healthy subjects. For example, in a subject having a particular disorder, an effective dose can be one that improves a diagnostic parameter, measurement, marker, etc. of that disorder by at least about 5%, at least about 10%, at least about 20%, at least about 25%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, or a dose that shows greater than a 90% improvement, where 100% is defined as the diagnostic parameter, measurement, marker, etc., exhibited by a normal subject.
[0037] The phrase "in an amount sufficient to effect a change" means that there is a detectable difference between the level of the indicator measured before administration of a particular therapy (e.g., baseline level) and after administration, whether the indicator is an objective parameter (e.g., serum concentration) or a subjective parameter (e.g., a subject's sense of well-being).
[0038] The terms "inhibitor" and "antagonist" or "activator" and "agonist" refer to inhibitory or activating molecules, respectively, with respect to the activation of, for example, a ligand, receptor, cofactor, gene, cell, tissue, or organ. An inhibitor is a molecule that reduces, blocks, prevents, delays, inactivates, desensitizes, or downregulates, for example, a gene, protein, ligand, receptor, or cell. An inhibitor can also be defined as a molecule that suppresses, blocks, or inactivates constitutive activity. An activator is a molecule that increases, activates, promotes, enhances activation, sensitizes, or upregulates, for example, a gene, protein, ligand, receptor, or cell. An "agonist" is a molecule that interacts with a target to increase or promote the activation of the target. An "antagonist" is a molecule that prevents the action(s) of an agonist. An antagonist prevents, suppresses, inhibits, or neutralizes the activity of an agonist; an antagonist can also prevent, inhibit, or suppress the constitutive activity of a target, e.g., a target receptor, even in the absence of an identified agonist.
[0039] The terms "modulate," "modulation," and the like refer to the ability of a molecule (e.g., an activator or inhibitor) to enhance or suppress, either directly or indirectly, the function or activity of a particular target, e.g., AXL. Modulators can act alone or can use cofactors, e.g., proteins, metal ions, or small molecules. Examples of modulators include small molecule compounds (e.g., compounds according to the present disclosure) and other bioorganic molecules.
[0040] The "activity" of a molecule may describe or refer to the binding of the molecule to a ligand or receptor; catalytic activity; the ability to stimulate gene expression or cell signaling, differentiation or maturation; antigenic activity; modulation of the activity of other molecules; etc. The term "proliferative activity" includes activity that promotes, requires, or is specifically associated with normal cell division, as well as cancer, tumors, metaplasia, cell transformation, metastasis, and angiogenesis.
[0041] As used herein, "comparable," "equivalent activity," "activity equivalent to," "equivalent effect," "equivalent effect to," and the like are relative terms that can be quantitatively and / or qualitatively recognized. The meaning of these terms often depends on the context in which they are used. As an example, two agents that activate a receptor may be recognized as having comparable effects from a qualitative standpoint, but if one agent achieves only 20% of the activity of the other agent as determined in an art-recognized assay (e.g., a dose-response assay) or in an art-recognized animal model, the two agents would not be recognized as having comparable effects from a quantitative standpoint. When comparing one result to another (e.g., comparing one result to a reference standard), "comparable" often (but not always) means that the one result deviates from the reference standard by less than 35%, less than 30%, less than 25%, less than 20%, less than 15%, less than 10%, less than 7%, less than 5%, less than 4%, less than 3%, less than 2%, or less than 1%. In certain embodiments, a result is comparable to a reference standard if the result deviates from the reference standard by less than 15%, less than 10%, or less than 5%. By way of example, activity or effect can refer to, but is not limited to, efficacy, stability, solubility, or immunogenicity.
[0042] "Substantially pure" indicates that a component (e.g., a compound according to the present disclosure) is present in greater than about 50% of the total content of the composition, typically greater than about 60% of the total content. More generally, "substantially pure" refers to a composition in which the component of interest constitutes at least 75%, at least 85%, at least 90%, or more of the total composition. In some cases, the component of interest comprises greater than about 90%, or greater than about 95%, of the total content of the composition.
[0043] The term "response," e.g., of a cell, tissue, organ, or organism, includes changes in biochemical or physiological behavior, e.g., changes in concentration, density, adhesion, or migration within a biological compartment, rate of gene expression, or state of differentiation, which changes correlate with internal mechanisms such as activation, stimulation, or treatment, or genetic programming. In certain contexts, terms such as "activation," "stimulation," and the like refer to cellular activation regulated by internal mechanisms and external or environmental factors; whereas terms such as "inhibition," "downregulation," and the like refer to the opposite effect.
[0044] A compound that is selective may be particularly useful in treating certain disorders or may reduce the potential for undesirable side effects. In certain embodiments, the compounds of the present disclosure are selective over other receptor tyrosine kinases (e.g., MER and / or TYRO3). Selectivity may be determined, for example, by comparing the inhibition of AXL by a compound described herein to the inhibition of another receptor tyrosine kinase (e.g., MER and / or TYRO3). In certain embodiments, the selective inhibition of AXL is at least 1000-fold, 500-fold, 100-fold, 50-fold, 40-fold, 30-fold, or 20-fold greater than the inhibition of the other receptor tyrosine kinase.

[0075] Synthesis method General Methods for Preparing the Claimed Compounds Common methods: Without limitation, useful methods for constructing compounds according to the present disclosure can consist of four components, which can be performed in any order: combining the a and b fragments, combining the b and c fragments, combining the c and d fragments, or modifying functional groups present on all of these fragments. A general retrosynthetic cleavage of the compounds into fragments a through d useful for constructing compounds of the present disclosure is shown below: [ka]
[0076] Several methods for preparing the claimed compounds are illustrated (Schemes 1-7). Scheme (1) shows one method for forming a bond between fragments a and b via reductive amination. The formation of the bond between fragments a and b can occur before or after the formation of the bond between fragments b and c. In the case of Scheme (1), the desired amine is coupled to the desired ketone via the use of a hydride source and acetic acid, or any other conditions known for reductive amination. [ka]
[0077] The relative positions of the amine and ketone can be reversed as well, as illustrated in equation (2). Those skilled in the art will recognize other possible conditions that will result in the desired connectivity and product. [ka]
[0078] Equation (3) shows another method for forming the ab fragment by first condensing the two partners and forming an amine, followed by the addition of a Grignard reagent. This sequence introduces an additional alkyl substituent at the carbon atom adjacent to the amine nitrogen atom. [ka]
[0079] The relative positions of the amine and ketone can be reversed as well, as exemplified in formula (4). One skilled in the art will recognize other possible conditions that will result in the desired connectivity and product. Formation of the ab fragment, as exemplified in formulas (1)-(4), can occur either before or after formation of the bc fragment. [ka]
[0080] The bond formation between fragments b and c can occur before or after the bond formation between fragments a and b or between fragments c and d. Equation (5) demonstrates one method for connecting fragments b and c via cross-coupling. Y can be selected from suitable groups such as B(OH)2, B(OR)2, ZnCl, MgBr, or SnR3. Z can be selected from suitable groups such as Cl, Br, I, and OTf. The coupling is mediated by a transition metal catalyst, preferably palladium, and a suitable ligand. The coupling can be assisted by an organic or inorganic base. The use of protecting groups for the bicyclic moiety, such as SEM, Boc, THP, PMB, MOM, MEM, or TIPS, generally improves the yield and purity of the desired product. [ka]
[0081] The relative functionalization of the binding partners can also be performed in the reverse direction, as shown in equation (6). Those skilled in the art will recognize other possible combinations and conditions that will result in the desired product. [ka]
[0082] The bond formation between fragments c and d can occur before or after the bond formation between fragments b and c. Equation (7) shows one method for connecting fragments c and d via cross-coupling. Y can be selected from suitable groups such as B(OH)2, B(OR)2, ZnCl, MgBr, and SnR3. Z can be selected from suitable groups such as Cl, Br, I, and OTf. The coupling is mediated by a transition metal catalyst, preferably palladium, and a suitable ligand. The coupling can be assisted by an organic or inorganic base. The use of protecting groups for the bicyclic moiety, such as SEM, Boc, THP, PMB, MOM, MEM, and TIPS, generally improves the yield and purity of the desired product. [ka]
[0083] For the most efficient preparation of any particular compound of the present disclosure, the timing and order of attachment of fragments, as well as the modification of functionality present on any of the fragments, may vary and depend on the functionality present. The various methods described above have been used to prepare compounds of the present disclosure and are exemplified below. The deuterated versions of the following examples can be synthesized using the appropriate deuterated intermediates.

[0124] In certain embodiments, the present disclosure contemplates the use of the compounds described herein in combination with adoptive cell therapy, a novel and promising form of personalized immunotherapy in which immune cells with anti-tumor activity are administered to cancer patients. Adoptive cell therapy has been studied using tumor-infiltrating lymphocytes (TILs) and T cells genetically engineered to express, for example, chimeric antigen receptors (CARs) or T cell receptors (TCRs). Generally, adoptive cell therapy involves collecting T cells from an individual, genetically modifying them to target specific antigens or enhance anti-tumor effects, expanding them to sufficient numbers, and then infusing the genetically engineered T cells into a cancer patient. T cells can be collected from the patient (e.g., autologous) for later reinfusion of the expanded cells, or they can be collected from a donor patient (e.g., allogeneic).
[0125] In certain embodiments, the present disclosure contemplates the use of the compounds described herein in combination with RNA interference-based therapy for silencing gene expression.RNAi begins by cleaving longer double-stranded RNA into small interfering RNA (siRNA).One strand of siRNA is incorporated into a ribonucleoprotein complex known as RNA-induced silencing complex (RISC), and then used to identify the mRNA molecule that is at least partially complementary to the incorporated siRNA strand.RISC can bind to mRNA or cleave it, both of which inhibit translation.
[0126] In certain embodiments, the present disclosure contemplates the use of the compounds described herein in combination with agents that target the extracellular production of adenosine. Such therapeutic agents may act on ectonucleotidases that catalyze the conversion of ATP to adenosine, such as ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1, also known as CD39 or cluster of differentiation 39), which hydrolyzes ATP to ADP and ADP to AMP, and ecto-5'-nucleotidase (NT5E or 5NT, also known as CD73 or cluster of differentiation 73), which converts AMP to adenosine. The enzymatic activities of CD39 and CD73 play strategic roles in modulating the duration, magnitude, and chemical nature of the purinergic signals delivered to various cells (e.g., immune cells). Alterations in the activity of these enzymes can alter the course or determine the outcome of several pathophysiological events, such as cancer, autoimmune diseases, infectious diseases, atherosclerosis, and ischemia-reperfusion injury, suggesting that these ectoenzymes represent novel therapeutic targets for addressing a variety of disorders. Exemplary anti-CD39 and anti-CD73 antibodies include ES002023, TTX-030, IPH-5201, SRF-617, CPI-006, oleculab (MEDI9447), NZV930, IPH5301, uriledolimab (TJD5, TJ004309), and BMS-986179. In certain embodiments, the present disclosure contemplates combination with inhibitors of CD73, e.g., those described in WO 2017 / 120508, WO 2018 / 094148, WO 2018 / 067424, and WO 2020 / 046813. In certain embodiments, the CD73 inhibitor is chemlicustat (AB680).
[0127] Another approach to targeting extracellular production of adenosine is adenosine A 2A and / or A 2B Thus, in some embodiments, the present disclosure provides a method for treating a cancer cell line comprising administering to a patient a compound according to the present disclosure and a compound ... 2A and / or A 2BCombination with agents that target receptors is contemplated. Such therapeutic agents include those that target the adenosine 2 receptor (A2R) (e.g., A 2A and / or A 2B ) antagonists. Adenosine binds to four different G protein-coupled receptors: A1R, A2R, and A3R. 2a R.A. 2b It can bind to and activate A3R and A3R. A3R is expressed on myeloid cells such as T cells, natural killer cells, and dendritic cells. 2a The binding of adenosine to R receptors increases intracellular levels of cyclic AMP, impairing the maturation and / or activation of such cells. This process significantly impairs the activation of the immune system against cancer cells. In addition, A 2A A2R is implicated in selectively potentiating anti-inflammatory cytokines, promoting upregulation of PD-1 and CTLA-4, promoting the generation of LAG-3 and Foxp3+ regulatory T cells, and mediating the inhibition of regulatory T cells. PD-1, CTLA-4, and other immune checkpoints are further described herein. Combinations of A2R antagonists in the combinations described herein may provide at least additive effects, given their different mechanisms of action. In some embodiments, the therapeutic agent can be an adenosine receptor antagonist described in WO / 2018 / 136700, WO 2018 / 204661, or WO 2020 / 023846. In some embodiments, the adenosine receptor antagonist is AB928 (i.e., etormadenant).
[0128] In certain embodiments, the present disclosure contemplates the use of inhibitors of phosphatidylinositol 3-kinase (PI3K), particularly the PI3Kγ isoform, in combination with the compounds described herein. PI3Kγ inhibitors can modulate myeloid cells to stimulate anti-cancer immune responses, for example, by inhibiting suppressive myeloid cells, attenuating immunosuppressive tumor-infiltrating macrophages, or stimulating macrophages and dendritic cells to produce cytokines that contribute to effective T-cell responses, thereby suppressing the development and spread of cancer. PI3Kγ inhibitors include those described in WO 2020 / 0247496A1.
[0129] In certain embodiments, the present disclosure contemplates the use of compounds described herein in combination with inhibitors of arginase, which have been shown to cause or contribute to pro-inflammatory immune dysfunction, tumor immune evasion, immunosuppression and immunopathology of infectious diseases. Exemplary arginase compounds can be found, for example, in PCT / US2019 / 020507 and WO / 2020 / 102646.
[0130] In certain embodiments, the present invention contemplates the use of an AXL inhibitor according to the present disclosure in combination with an inhibitor of HIF-2α, which plays an essential role in the cellular response to low oxygen availability. Under hypoxic conditions, hypoxia-inducible factor (HIF) transcription factors can activate the expression of genes that regulate metabolism, angiogenesis, cell proliferation and survival, immune evasion, and inflammatory responses. Overexpression of HIF-2α is associated with poor clinical outcomes in patients with various cancers; hypoxia is also prevalent in numerous acute and chronic inflammatory diseases, such as inflammatory bowel disease and rheumatoid arthritis. Examples of HIF-2α inhibitors include velzutifan, ARO-HIF2, PT-2385, AB521, and those described in WO 2021113436 and WO 2021188769. In some embodiments, an AXL inhibitor according to the present disclosure is combined with AB521.
[0131] The present disclosure also contemplates the combination of an AXL inhibitor described herein with one or more RAS signaling inhibitors. Oncogenic mutations in RAS family genes, such as HRAS, KRAS, and NRAS, are associated with various cancers. For example, in KRAS family genes, mutations G12C, G12D, G12V, G12A, G13D, Q61H, Q13C, and G12S, among others, have been observed in multiple tumor types. Direct and indirect inhibition approaches to inhibit mutant RAS signaling have been investigated. Indirect inhibitors target effectors other than RAS in the RAS signaling pathway, and these inhibitors include, but are not limited to, inhibitors of RAF, MEK, ERK, PI3K, PTEN, SOS (e.g., SOS1), mTOR (e.g., mTORC1), SHP2 (PTPN11), and AKT. Examples of indirect inhibitors under development include, but are not limited to, RMC-4630, RMC-5845, RMC-6291, RMC-6236, JAB-3068, JAB-3312, TNO155, RLY-1971, and BI1701963. Direct inhibitors of RAS mutants are also under investigation, generally targeting the KRAS-GTP complex or the KRAS-GDP complex. Exemplary direct RAS inhibitors under development include, but are not limited to, sotorasib (AMG510), MRTX849, mRNA-5671, and ARS1620. In some embodiments, the one or more RAS signaling inhibitors are selected from the group consisting of a RAF inhibitor, a MEK inhibitor, an ERK inhibitor, a PI3K inhibitor, a PTEN inhibitor, an SOS1 inhibitor, an mTOR inhibitor, a SHP2 inhibitor, and an AKT inhibitor. In other embodiments, the one or more RAS signaling inhibitors directly inhibit RAS mutants.
[0132] In some embodiments, the one or more additional therapeutic agents are: (i) agents that inhibit the enzyme poly(ADP-ribose) polymerase (e.g., olaparib, niraparib, and rucaparib, etc.); (ii) inhibitors of the Bc1-2 family of proteins (e.g., venetoclax, navitoclax, etc.); (iii) inhibitors of MCL-1; (iv) inhibitors of the CD47-SIRPα pathway (e.g., anti-CD47 antibodies); (v) isocitrate dehydrogenase (IDH) inhibitors, e.g., IDH-1 or IDH-2 inhibitors (e.g., ivosidenib, enasidenib, etc.).
[0133] Immune Checkpoint Inhibitors The present disclosure contemplates the use of inhibitors of AXL described herein in combination with immune checkpoint inhibitors.
[0134] The vast array of genetic and epigenetic alterations characteristic of all cancers provides a diverse array of antigens that the immune system can use to distinguish tumor cells from their normal counterparts. In the case of T cells, the ultimate amplitude (e.g., level of cytokine production or proliferation) and quality (e.g., type of immune response generated, including the pattern of cytokine production) of the response initiated by the T cell receptor (TCR) upon antigen recognition are regulated by the balance between costimulatory and inhibitory signals (immune checkpoints). Under normal physiological conditions, immune checkpoints are important for preventing autoimmunity (i.e., maintaining self-tolerance) when the immune system is responding to pathogen infection and for protecting against tissue damage. The expression of immune checkpoint proteins can be dysregulated by tumors, serving as an important immune resistance mechanism.
[0135] T cells have focused much of their efforts on therapeutically manipulating endogenous antitumor immunity due to their i) ability to selectively recognize peptides derived from proteins in all cellular compartments, ii) ability to directly recognize and kill antigen-expressing cells (by CD8+ effector T cells; also known as cytotoxic T lymphocytes (CTLs)), and iii) ability to orchestrate diverse immune responses exerted by CD4+ helper T cells that integrate adaptive and innate effector mechanisms.
[0136] In clinical settings, blockade of immune checkpoints leading to the amplification of antigen-specific T cell responses has shown promise in the treatment of human cancers.
[0137] T cell-mediated immunity involves multiple sequential steps, each of which involves counteracting and modulating stimulatory and inhibitory signals to optimize the response. Nearly all inhibitory signals in an immune response ultimately regulate intracellular signaling pathways, many of which are initiated through membrane receptors, and their ligands are either membrane-bound or soluble (cytokine) in nature. Costimulatory and inhibitory receptors and ligands that regulate T cell activation are less frequently overexpressed in cancer compared with normal tissues, whereas inhibitory ligands and receptors that regulate T cell effector function in tissues are commonly overexpressed in tumor cells or in non-transformed cells associated with the tumor microenvironment. The function of soluble and membrane-bound receptor-ligand immune checkpoints can be modulated, for example, using agonistic antibodies (for costimulatory pathways) or antagonistic antibodies (for inhibitory pathways). Thus, in contrast to most antibodies currently approved for cancer therapy, immune checkpoint-blocking antibodies do not target tumor cells directly, but rather target lymphocyte receptors or their ligands to enhance intrinsic antitumor activity [see Pardoll, (April 2012) Nature Rev. Cancer 12:252-64].
[0138] Examples of immune checkpoints (ligands and receptors), some of which are selectively upregulated in various types of tumor cells, making them candidates for blockade, include PD-1 (programmed cell death protein 1), PD-L1 (PD-1 ligand), BTLA (B- and T-lymphocyte attenuator), CTLA-4 (cytotoxic T-lymphocyte-associated antigen 4), TIM-3 (T-cell membrane protein 3), LAG-3 (lymphocyte-activation gene 3), TIGIT (T-cell immunoreceptor with Ig and ITIM domains), and killer inhibitory receptors, which can be divided into two classes based on structural features: i) killer cell immunoglobulin-like receptors (KIRs) and ii) C-type lectin receptors (members of the type II transmembrane receptor family). Other less well-defined immune checkpoints have been described in the literature, including both receptors (e.g., the 2B4 (also known as CD244) receptor) and ligands (e.g., certain B7 family inhibitory ligands such as B7-H3 (also known as CD276) and B7-H4 (also known as B7-S1, B7x, and VCTN1)) [see Pardoll, (April 2012) Nature Rev. Cancer 12:252-64].
[0139] The present disclosure contemplates the use of the AXL inhibitors described herein in combination with inhibitors of the immune checkpoint receptors and ligands described above, as well as immune checkpoint receptors and ligands yet to be described. Certain modulators of immune checkpoints are currently approved, and many others are in development. In 2011, the fully humanized CTLA-4 monoclonal antibody ipilimumab (YERVOY®, Bristol-Myers Squibb) became the first immune checkpoint inhibitor to receive regulatory approval in the United States when it was approved for the treatment of melanoma. Fusion proteins containing CTLA-4 and antibodies (CTLA4-Ig, abatacept (ORENCIA®, Bristol-Myers Squibb)) have been used to treat rheumatoid arthritis, and other fusion proteins have shown efficacy in kidney transplant patients sensitized to Epstein-Barr virus. The next class of immune checkpoint inhibitors to receive regulatory approval were directed against PD-1 and its ligands, PD-L1 and PD-L2. Approved anti-PD-1 antibodies include nivolumab (OPDIVO®, Bristol-Myers Squibb) and pembrolizumab (KEYTRUDA®, Merck), which are used for a variety of cancers, including squamous cell carcinoma, classical Hodgkin lymphoma, and urothelial carcinoma. Approved anti-PD-L1 antibodies include avelumab (BAVENCIO®, EMD Serono & Pfizer), atezolizumab (TECENTRIQ®, Roche / Genentech), and durvalumab (IMFINZI®, AstraZeneca), which are used for certain cancers, including urothelial carcinoma. Another approach to targeting the PD-1 receptor is a recombinant protein called AMP-224, which consists of the extracellular domain of PD-L2 (B7-DC) fused to the Fc portion of IgG1.Therapies targeting TIGIT or its ligands CD155 and CD112 are not approved but are in development, including BMS-986207 (Bristoll-Myers Squibb), tiragolumab (Roche / Genentech), OMP-31M32 (OncoMed), etigilimab, osipellimab, vibostolimab, AB308, and AB154 (domvanalimab).
[0140] In one or more embodiments, one or more of the additional therapeutic agents is a cancer immunotherapy (e.g., an immune checkpoint inhibitor). In some embodiments, the cancer immunotherapy is a PD-1 antagonist, e.g., an antagonistic PD-1 antibody. Suitable PD-1 antibodies include, for example, OPDIVO® (nivolumab), KEYTRUDA® (pembrolizumab), MEDI-0680 (AMP-514; WO2012 / 145493), balstilimab, budigalimab, camrelizumab, cemiplimab, dostallimab, emiprimab, ezabenlimab, pimivalimab, retifanlimab, sasanlimab, spartalizumab, sintilumab, tislelizumab, toripalimab, or zimberelimab. Another potential cancer immunotherapy drug is pidilizumab (CT-011), although its specificity for PD-1 binding has been questioned.
[0141] In some embodiments, the cancer immunotherapeutic agent targets PD-L1 and is a PD-L1 antagonist, e.g., an antagonistic PD-L1 antibody. Suitable PD-L1 antibodies include, for example, TECENTRIQ® (atezolizumab, MPDL3280A, WO2010 / 077634), IMFINZI® (durvalumab, MEDI4736), BMS-936559 (WO2007 / 005874), cosibelimab, embafolimab, and avelumab (MSB0010718C, WO2013 / 79174).
[0142] In some combinations provided herein, a compound according to the disclosure is combined with one or more immune checkpoint inhibitors selected from MEDI-0608, nivolumab, pidilizumab, pembrolizumab, avelumab, atezolizumab, durvalumab, cemiplimab, sintilimab, tislelizumab, AB308, domvanalimab, and zimberelimab.
[0143] In certain embodiments of the present disclosure, the claimed AXL inhibitors are combined with cancer immunotherapeutics that are (i) agonists of stimulatory (including costimulatory) receptors or (ii) antagonists of inhibitory (including coinhibitory) signals in T cells, both of which amplify antigen-specific T cell responses.

[0171] dosage The AXL inhibitors of the present disclosure may be administered to a subject in an amount determined, for example, by the goal of administration (e.g., desired degree of achievement), the age, weight, sex, and health and physical condition of the subject to whom the formulation is administered, the route of administration, and the nature of the disease, disorder, condition, or symptom. The dosing regimen may also take into account the presence, nature, and extent of any adverse effects associated with the administered agent(s) and previous or concomitant therapy. Effective dosages and administration regimens can be readily determined, for example, from safety and dose escalation studies, in vivo studies (e.g., animal models).
[0172] Generally, dosage parameters indicate that the dosage is below the amount that is irreversibly toxic to the subject (maximum tolerated dose (MTD)) and at least the amount necessary to have a measurable effect on the subject, determined, for example, by ADME-related pharmacokinetic and pharmacodynamic parameters, taking into account the route of administration and other factors.
[0173] Generally, the disclosed methods involve administering an effective amount of a compound described herein, or a pharmaceutically acceptable salt or solvate thereof, or a composition thereof, to a subject in need thereof. An "effective amount," with respect to AXL inhibitors of the present disclosure, refers to an amount of compound sufficient to engage a target (by inhibiting, agonizing, or antagonizing the target) at a level indicative of the compound's efficacy. In the case of AXL, target engagement can be determined by one or more biochemical or cellular assays that yield an EC50, ED50, EC90, IC50, or similar value that can be used as an assessment of a compound's efficacy. Assays for determining target engagement include, but are not limited to, those described in the Examples. An effective amount can be administered as a single amount or in multiple smaller amounts (e.g., one tablet of "x" amount, two tablets each of "x / 2" amount, etc.).
[0174] In certain embodiments, AXL inhibitors contemplated by the present disclosure can be administered at a dosage level of about 0.01 mg / kg to about 50 mg / kg, or about 1 mg / kg to about 25 mg / kg of subject body weight / day, one or more times per day (e.g., orally, parenterally) to achieve the desired therapeutic effect.
[0175] For oral administration, the compositions can be provided in the form of tablets, capsules, etc., containing 1 to 1000 mg of the active ingredient (i.e., 1, 3, 5, 10, 15, 20, 25, 50, 75, 100, 150, 200, 250, 300, 400, 500, 600, 750, 800, 900, and 1000 milligrams of the active ingredient of a compound of formula (I) in particular).
[0176] In certain embodiments, the desired dose of AXL inhibitor is contained in a "unit dosage form." The phrase "unit dosage form" refers to physically discrete units, each containing a predetermined amount of an AXL inhibitor, alone or in combination with one or more additional active agents, sufficient to provide a desired effect. It is understood that the parameters of the unit dosage form depend on the particular active agent and the effect to be achieved. For intravenous administration, a unit dosage form may contain 1 to 1000 milligrams of active ingredient (i.e., a compound of formula (I), particularly 1, 10, 25, 50, 100, 200, 300, or 500 milligrams).

[0185] Example 1: 3-(4-(cyclopropylsulfonyl)phenyl)-5-(7-methyl-7-((R)-2-methylpyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulen-2-yl)-1H-pyrazolo[3,4-b]pyridine [ka]
[0186] Step a: To a mixture of 5-bromo-3-iodo-1H-pyrazolo[3,4-b]pyridine (25.0 g, 77.2 mmol), camphorsulfonic acid (1.79 g, 7.72 mmol), and THF (193 mL) was added 3,4-dihydro-2H-pyran (14.1 mL, 154 mmol) at room temperature. The mixture was stirred at 65° C. for 3 hours, cooled to room temperature, and 28% by weight of NH 3(水溶液) The reaction was quenched with 10 mL of HCl. The mixture was concentrated onto silica gel and purified by column chromatography (hexane:EtOAc, 4:1) to give the desired product as a white solid (26.8 g, 85%).
[0187] Step b: A mixture of 1-bromo-4-(cyclopropylsulfonyl)benzene (12.9 g, 49.3 mmol), B2pin2 (12.5 g, 49.3 mmol), (dppf)PdCl2 (1.80 g, 2.46 mmol), and KOAc (9.67 g, 98.6 mmol) was placed under nitrogen. Degassed dioxane (246 mL) was added, and the reaction mixture was stirred at 100 °C for 1 h. The mixture was cooled to room temperature, concentrated, diluted with EtOAc (250 mL), filtered through Celite to remove solids, and concentrated again to give the desired product, which was used directly in Step c.
[0188] Step c: A mixture of the product from step a (20.1 g, 49.3 mmol), the product from step b (estimated 49.3 mmol), (dppf)PdCl (3.61 g, 4.93 mmol), and KCO (13.6 g, 98.6 mmol) was placed under nitrogen.
