Definitions
- the present invention relates generally to use of a mithramycin analogue and more specifically to the use of such analogues for the treatment of cancer.
- chemotherapeutic drugs often reduce a cell’s ability to reproduce, or they kill cells that reproduce quickly.
- First-generation chemotherapeutic drugs were designed from chemicals found to have highly toxic side effects, such as dyes or chemical warfare agents. The chemicals were then modified or used as discovered and harnessed for treating cancer. Over time, various classes of chemotherapeutic drugs have been developed, but despite the variety of available drugs, cancer often recurs after a period of remission, and some cancers are resistant to treatment.
- Treatment of cancerous cells often requires repeated rounds of chemotherapy and can include radiation therapy or surgery as well.
- Cells that are susceptible to one drug can develop resistance to the drug over time, requiring a change in therapy.
- Combinations of drugs are also used, targeting multiple physiological pathways at once to treat the cancer. Because different chemotherapeutic agents target different physiological pathways, there is a constant need to find new chemicals that can target different types or stages of cancer.
- SWItch/Sucrose Non-Fermentable Complex SWI/SNF
- SWI/SNF complexes are found in eukaryotes, including both yeast and humans. These complexes are large multi-unit complexes that expose nucleic acid to a cell’s transcription/translation mechanisms through modification of the associations between nucleic acid and histones.
- chromatin remodeling enzymes push and slide nucleosomes along DNA, and mutations in SWI/SNF are some of the most common mutations that make a cancer resistant to chemotherapy. Development of agents that can target such cancers is an ongoing challenge.
- the SMARCA4 gene provides instructions for making a protein called BRG1, which forms one piece (subunit) of several different protein groupings called SWI/SNF protein complexes.
- SWI/SNF complexes regulate gene activity (expression) by a process known as chromatin remodeling.
- Chromatin is the network of DNA and protein that packages DNA into chromosomes. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged.
- Chromatin remodeling is one way gene expression is regulated during development; when DNA is tightly packed, gene expression is lower than when DNA is loosely packed.
- the BRG1 protein uses a molecule called ATP to provide energy for chromatin remodeling, although the protein's specific role in remodeling is unclear.
- the present invention relates to the use of a mithramycin analog, also known as EC-8042 or AIT-102, for the treatment of cancer.
- the invention provides a compound of Formula (I),

Description
USE OF MITHRAMYCIN ANALOGUE FOR THE TREATMENT OF CANCER
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63/565,421, filed March 14, 2024, and U.S. Provisional Application No. 63/631,852, filed April 9, 2024. The contents of the prior applications are considered part of and are hereby incorporated by reference in their entirety.
FIELD OF THE INVENTION
[0002] The present invention relates generally to use of a mithramycin analogue and more specifically to the use of such analogues for the treatment of cancer.
BACKGROUND INFORMATION
[0003] Various small molecules are used in chemotherapy to reduce uncontrolled proliferation caused by cancer cells. Chemotherapeutic drugs often reduce a cell’s ability to reproduce, or they kill cells that reproduce quickly. First-generation chemotherapeutic drugs were designed from chemicals found to have highly toxic side effects, such as dyes or chemical warfare agents. The chemicals were then modified or used as discovered and harnessed for treating cancer. Over time, various classes of chemotherapeutic drugs have been developed, but despite the variety of available drugs, cancer often recurs after a period of remission, and some cancers are resistant to treatment.
[0004] Treatment of cancerous cells often requires repeated rounds of chemotherapy and can include radiation therapy or surgery as well. Cells that are susceptible to one drug can develop resistance to the drug over time, requiring a change in therapy. Combinations of drugs are also used, targeting multiple physiological pathways at once to treat the cancer. Because different chemotherapeutic agents target different physiological pathways, there is a constant need to find new chemicals that can target different types or stages of cancer.
[0005] Chemotherapeutic agents usually target cells at active stages of cell division; thus, mutations in enzymes regulating cell division can cause resistance of cancers to various chemicals. One such enzyme is the multi-unit complex SWItch/Sucrose Non-Fermentable Complex (SWI/SNF), first discovered in yeast cells with mutations in their ability to switch mating types and to ferment sucrose. SWI/SNF complexes are found in eukaryotes, including both yeast and humans. These complexes are large multi-unit complexes that expose nucleic acid to a cell’s
transcription/translation mechanisms through modification of the associations between nucleic acid and histones. Such chromatin remodeling enzymes push and slide nucleosomes along DNA, and mutations in SWI/SNF are some of the most common mutations that make a cancer resistant to chemotherapy. Development of agents that can target such cancers is an ongoing challenge.
[0006] The SMARCA4 gene provides instructions for making a protein called BRG1, which forms one piece (subunit) of several different protein groupings called SWI/SNF protein complexes. SWI/SNF complexes regulate gene activity (expression) by a process known as chromatin remodeling. Chromatin is the network of DNA and protein that packages DNA into chromosomes. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged. Chromatin remodeling is one way gene expression is regulated during development; when DNA is tightly packed, gene expression is lower than when DNA is loosely packed. The BRG1 protein uses a molecule called ATP to provide energy for chromatin remodeling, although the protein's specific role in remodeling is unclear.
[0007] In addition to the challenges of overcoming a cancer’s defense against chemotherapy, the side effects of chemotherapy create a difficult hurdle for cancer treatment development. Chemotherapeutic agents are by nature destructive and have high rates of side effects related to use of toxic chemicals. Development of small molecule drugs for cancer treatment takes into consideration effectiveness, types of cancers effected, and numbers and severity of associated adverse events. Despite the improvement seen in cancer treatments available worldwide, there is still a need to develop effective cancer treatments that have manageable levels of negative side effects.
[0008] Successful development of chemotherapeutic agents relies on both construction of new molecules and research on new uses of molecules already known. The need to treat cancer with multiple, the difficulty of finding drugs effective on any given type of cancer, and the high level of side effects makes drug development especially challenging. There is therefore incentive to provide improved means of treating resistant cancers effectively and without adverse side effects.

DETAILED DESCRIPTION OF THE INVENTION
[0037] Before the present compositions and methods are described, it is to be understood that this invention is not limited to particular compositions, methods, and experimental conditions described, as such compositions, methods, and conditions may vary. It is also to be understood that the terminology used herein is for purposes of describing particular embodiments only, and is not intended to be limiting, since the scope of the present invention will be limited only in the appended claims.
[0038] All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference.
[0039] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, it will be understood that modifications and variations are encompassed within the spirit and scope of the instant disclosure. The preferred methods and materials are now described.
[0040] As used in this specification and the appended claims, the singular forms “a,” “an”, and “the” include plural references unless the context clearly dictates otherwise. Thus, for example,
references to “the method” includes one or more methods, and/or steps of the type described herein which will become apparent to those persons skilled in the art upon reading this disclosure and so forth.
[0041] As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
[0042] As used herein, the term “beneficial effect” or “efficacious” refers to an improvement of symptoms of a disease, reduction in detrimental symptoms, improvement of clinical test results, reduction in pain, improvement of quality of life, or other desirable results.
[0043] The terms “administration” and or “administering” as used herein refer to providing the composition of the disclosure in a therapeutically effective amount to the subject in need of treatment. Administration routes include but are not limited to intracutaneous, subcutaneous, intravenous, intralesional, intratumoral, intraperitoneal, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, transdermal, transtracheal, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal, oral, sublingual buccal, rectal, vaginal, nasal ocular administrations, as well infusion, inhalation, and nebulization.
[0044] In some aspects, administration is in combination with one or more additional therapy. The phrases “combination therapy,” “combined with” and the like refer to the use of more than one medication or treatment simultaneously to increase the response. In some embodiments, the present composition is used in combination with a chemotherapeutic agent, for example, immunomodulating agents, altretamine, busulfan, carboplatin, carmustine, cisplatin, cyclophosphamide, dacarbazine, ifosfamide, lomustine, melphalan, temozolomide, trabectedin, 5- fluorouracil, 6-mercaptopurine, azacitidine, capecitabine, clofarabine, cytarabine, floxuridine, fludarabine, gemcitabine, methotrexate, pemetrexed, pentostatin, pralatrexate, a combination of trifluridine and tipiracil, vincristine, vinblastine, vinorelbine, paclitaxel, docetaxel, etoposide, teniposide, irinotecan, or topotecan.Such therapies can be administered prior to, simultaneously with, or following administration of the composition of the present disclosure.
[0045] As used herein, the term “treatment” refers to an approach or regimen designed to improve or alleviate symptoms of a disease, sickness, or infirmity. Treatment can lead to reduction in pain, improvement of quality of life, or decrease in size, number, or distribution of a tumor, cancer, or cancerous cells. In some aspects, treatment of a cancer results in tumor shrinkage or a reduction in the number of cancer cells. Treatment of cancer also occurs when symptoms or tests for cancer or cancerous cells are improved, or when symptoms or tests for cancer or cancerous
cells do not worsen or stabilize. Failure of treatment occurs in some aspects, when a tumor metastasizes, grows in size, does not shrink, or when cancer cells increase in number. In some aspects, the present methods are used after a cancer has been treated with a chemotherapy agent and treatment has failed.
[0046] Treatments for cancer referred to herein include chemotherapy, corticosteroids, an immunomodulating agent, a proteasome inhibitor, a histone deacetylase (HDCA) inhibitor, immunotherapy, a nuclear export inhibitor, stem cell transplant, radiation therapy, surgery, and any combination thereof. Surgical treatments include, for example, cryosurgery, electrosurgery, laser surgery, Mohs surgery, laparoscopic surgery, segmentectomy, resection, lobectomy, robotic surgery, and chemical ablation. Radiation treatments include, for example, 3D conformal radiation therapy (3DCRT), image guided radiation therapy (IGRT), intensity modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), brachytherapy, intraoperative radiation therapy (IORT), stereotactic radiosurgery (SRS), proton therapy, and stereotactic body radiation therapy (SBRT).
[0047] The term “chemotherapy” or “chemotherapeutic agent” as used herein refers to any therapeutic agent used to treat cancer. A chemotherapeutic agent includes any substance or agent having a toxic effect on cells resulting in cell death or reduced proliferation. Chemotherapy targets cells at various cell cycle stages to inhibit or disrupt cell reproduction and proliferation. Chemotherapeutic agents include cell-cycle nonspecific agents and cell-cycle specific agents. Chemotherapy that is used for the treatment of cancers described herein includes, for example, altretamine, busulfan, carboplatin, carmustine, cisplatin, cyclophosphamide, dacarbazine, ifosfamide, lomustine, melphalan, temozolomide, trabectedin, 5 -fluorouracil, 6-mercap topurine, azacitidine, capecitabine, clofarabine, cytarabine, floxuridine, fludarabine, gemcitabine, methotrexate, pemetrexed, pentostatin, pralatrexate, trifluridine, tipiracil, vincristine, vinblastine, vinorelbine, paclitaxel, docetaxel, etoposide, teniposide, irinotecan, or topotecan.
[0048] Immunomodulating agents include checkpoint inhibitors, for example, anti-PDl or anti- CTLA4 inhibitors. Illustrative examples include pembrolizumab, nivolumab, cemiplimab, atezolizumab, avelumab, durvalumab, ipilimumab, tremelimumab, relatlimab, or a combination thereof.
[0049] Studies have revealed that SWI/SNF is a tumor suppressor in a number of diverse malignancies. Several studies have also revealed that subunits of the mammalian complex, including SMARCB1, PBRM1, SMARCB1, SMARCA4, and ARID2, are frequently mutated in
human cancers. The present disclosure shows that F(l) was effective in reducing the number of viable cancer cells with such mutations in at least lung cancer, synovial sarcoma, and hepatocellular carcinoma.
[0050] Synovial sarcoma (SS) is an aggressive malignant tumor that originates in mesenchymal tissue. SS is usually associated with mutations that create a translocation of a synaptotagmin (SYT) gene on chromosome 18 to an SSX gene that is involved in synovial sarcomas on chromosome X. This translocation forms a SYT-SSX fusion transcript, thought to function as an aberrant transcriptional regulator. Despite years of research, a diagnosis of SS still leads to poor prognosis for subjects. As presented herein, F(l) was found to significant decrease viability in HS-SY-II cells, which is a large step forward in cancer treatment for SS.
[0051] In one embodiment, the invention provides a method of treating cancer in a subject including administering to the subject a compound of Formula (I),
Formula (I) or a salt, co-crystal or solvate thereof for the treatment of cancer in a subject. In one aspect treatment of cancer is with the proviso that the cancer is not a rhabdoid tumor.
[0052] In one embodiment, the invention provides a method of treating cancer in a subject, comprising: a) analyzing the cancer for presence of a mutation or an alteration in level of expression of a gene or protein; b) determining that the cancer is sensitive to treatment based on the presence of the mutation or alteration in the level of expression of the gene or protein; and c) administering to the subject a compound of Formula (I),
Formula (I) or a salt, co-crystal or solvate thereof. In one aspect treatment of cancer is with the proviso that the cancer is not a rhabdoid tumor when a mutation in the cancer is a SWI-SNF mutation.

[0054] In one embodiment, said composition is a pharmaceutical composition. The compound of Formula (I) is also known as demycarosyl-3D-3-D-digitoxosyl- mithramycin SK and is referred to herein as F(l). In some aspects, the compound of Formula (I) is a salt, a hydrochloride salt, a phosphate salt, a sulfate salt, a mesylate salt, a sodium salt, a citrate salt, a tartrate salt, a succinate sat, a hydrobromide salt, a glutamate salt, or a malate salt. The compound of Formula (I) may be obtained from genetically modified bacteria by combinatorial biosynthesis, specifically by fermentation of Streptomyces argillaceus M3Wl-pMP*3BII (J. Med. Chem. (2012) 55:5813 - 5825). The compound of Formula (I) is currently under development as antitumor agent due to the fact that it inhibits replication and transcription processes during macromolecular biosynthesis, by virtue of its affinity towards GC-rich DNA regions located at the minor groove of DNA, especially the site of union of the Spl transcription factor. Consequently, proteins whose expression is affected by this drug include various protooncogenes, proteins involved in
angiogenesis or antiapoptotic processes, p53-mediated transcriptional responses, as well as multidrug resistant gene 1 (MDR-1). The compound of Formula (I) is 10 times less toxic than mithramycin in vivo, and therefore has a greater therapeutic window while it is active both in vitro and in cancer xenograft models. The compound of Formula (I) is disclosed in US Patent No. 8,772,253 and US Patent No. 10,568,899, the contents of which are incorporated herein by reference in their entirety.
[0055] The pharmaceutical composition may also contain other therapeutic agents, and may be formulated, for example, by employing conventional vehicles or diluents, as well as pharmaceutical additives of a type appropriate to the mode of desired administration (for example, excipients, preservatives, etc.) according to techniques known in the art of pharmaceutical formulation.

Other mutations will be known to those of skill in the art. In one aspect, when the cancer includes a SWI-SNF mutation, the cancer is one that is not a rhabdoid tumor.
[0079] A “SMARCA4” or “BRG1” gene refers to a gene that encodes a protein involved in chromatin remodeling, which is crucial for regulating the binding of transcription factors to DNA. The SMARCA4 protein is a key component of the SWI/SNF complex, playing a significant role in gene expression, DNA repair, and cell cycle control. Mutations or alterations in SMARCA4 are associated with various cancers and developmental disorders, highlighting its importance as a tumor suppressor gene. The functional implications of SMARCA4 in cellular processes and its potential therapeutic applications are considered in the context of the disclosure described herein.
[0080] “SWI-SNF” or “SWItch/Sucrose Non-Fermentable” refers to a subfamily of ATP- dependent chromatin remodeling complexes found in eukaryotes. These complexes play a crucial role in regulating gene expression by altering the structure of chromatin, thereby facilitating or hindering the access of transcription factors to DNA. The SWI-SNF complex utilizes energy from ATP hydrolysis to reposition nucleosomes, which are the basic units of chromatin, enabling the activation or repression of specific genes. Mutations or dysregulation of SWI-SNF components have been linked to various cancers and developmental disorders, underscoring its importance in maintaining genomic integrity and cellular function.
[0081] “SYT-SSX” refers to a fusion gene resulting from the chromosomal translocation t(X;18)(pl 1.2;ql 1.2), commonly found in synovial sarcomas. This translocation fuses the SYT gene on chromosome with one of the SSX genes (SSX1, SSX2, or SSX4) on the X chromosome, creating a chimeric gene that encodes the SYT-SSX fusion protein. The SYT-SSX protein combines the transcriptional activation domain of SYT with the transcriptional repression domain of SSX, leading to aberrant gene expression. This fusion protein is implicated in the malignant transformation and proliferation of synovial sarcoma cells by affecting critical pathways such as cyclin DI expression. The role of SYT-SSX in oncogenesis and its potential as a therapeutic target are considered in the context of the applications described herein.
[0082] “MYC” refers to a proto-oncogene that encodes a transcription factor involved in the regulation of various cellular processes, including cell growth, proliferation, and apoptosis. The MYC gene family includes c-MYC, L-MYC, and N-MYC, each playing critical roles in normal cellular function and development. Aberrations in MYC expression or function, such as overexpression or mutations, are implicated in the pathogenesis of numerous cancers, including Burkitt lymphoma and various carcinomas. The MYC protein influences gene expression by binding to specific DNA sequences, thereby regulating the transcription of target genes.
[0083] “ARID 1 A” or “AT -rich interaction domain-containing protein 1A” refers to a gene that encodes a protein involved in chromatin remodeling, which is essential for regulating gene expression. The ARID 1 A protein is a key subunit of the SWI/SNF complex, which modulates the structure of chromatin to facilitate or inhibit the access of transcription factors to DNA. Mutations or alterations in ARID 1 A are frequently observed in various cancers, including ovarian, endometrial, and gastric cancers, where they often lead to loss of function and contribute to tumorigenesis.
[0084] “SMARCA2/4” refers to genes that encode proteins belonging to the SWI/SNF family of chromatin remodeling complexes. These proteins, also known as BRM (Brahma) and BRG1 (Brahma-related gene 1), respectively, play crucial roles in regulating gene expression by altering chromatin structure to facilitate or inhibit the access of transcription factors to DNA. Both SMARCA2 and SMARCA4 possess ATPase activity, which provides the energy required for chromatin remodeling. Mutations or alterations in these genes are associated with various cancers and developmental disorders, highlighting their importance in maintaining genomic stability and proper cellular function.

Example 3
Cell viability with AIT-102 Treatment
[0091] There was a decrease in percent viability of A549 cells, with a SMARCA4 mutation, treated with F(l) compared to a control treatment (less than 15% viability for F(l)-treated cells, see FIG. 1). For SK-LU-1 cells containing an ARID1A mutation, treatment with F(l) resulted in less than 50% viability (see FIG. 2). SNU398 cells, with a SMARCA2/4 mutation, were even more susceptible to treatment with F(l), and results indicated that less than 5% of cells were viable after treatment (see FIG. 3). The previous three cell lines all have SWI/SNF mutations; a cell line with a SYT-SSX fusion transcript (HS-SY-II) was surprisingly susceptible to treatment with F(l) as well, with less than 20% of cells viable after treatment (see FIG. 4). There was a significant decrease in percent viability of RL95-2 cells, endometrial cancer cells, treated with F(l) compared to a control treatment (see FIG. 8C). Viability of Capan-2 cells, pancreatic cancer cells, treated
with F(l) was decreased compared to a control treatment (see FIG. 8D). Viability of Bud-8 cells, noncancerous cells, treated with F(l) was decreased compared to a control treatment (see FIG. 5). Viability of BUD8, A673, RL952, CAPAN2, HEK293, HS-SY-II, and hl299 cells was decreased with increasing concentration of the treatment (see FIG. 6A-6H).
