[0002] Technical Field The present invention describes a method for treating or ameliorating the symptoms of cancer in human or animal subjects by agents and compositions designed to promote anti-tumor activity.Exemplary synergistic pharmaceutical treatments include a combination of active agents, including an agent for inhibiting or suppressing the expression of TGF-β2, combined with an agent or formulation containing irinotecan.Biomarkers can be used to select subjects who will benefit from the agent, use, or method. [Background technology]

[0003] background Cancer is a complex pathology that involves multiple different cellular pathways. Due to this complexity, it has been difficult to find an effective therapy that can have sufficient anti-tumor activity against various cancers. What's worse, cancer cells and malignant tumors may develop resistance to various agents and drugs, which may cause patients to become unresponsive.

[0004] Irinotecan is an example of a conventional therapy that has been used for various malignant tumors. The drawbacks of conventional therapies, such as compositions containing irinotecan, include a lack of sufficient efficacy against a wide range of cancers. Additional drawbacks include the development of resistance to irinotecan, which can limit successful treatment outcomes. An additional drawback of using compositions containing irinotecan is cross-resistance to other anticancer drugs. Furthermore, not all cancer patients reliably respond to irinotecan-based therapy and must instead receive palliative care. These drawbacks can limit available treatment options.

[0005] What is needed to overcome these difficulties are methods and uses that employ combinations of compositions and agents that enhance efficacy against malignancies and avoid the effects of resistance.

[0006] There is an urgent need for compositions, agents, uses and methods that combine various agents with significant anti-tumor activity.There is also a need for improved guidance in the use of such compositions and agents by using appropriate clinically validated biomarkers to provide synergistic improvements in efficacy.

[0085] Methods and compositions for cancer In many cancers, such as pancreatic cancer and melanoma, patients show high levels of TGF-β2 expression.The agent that inhibits or suppresses the expression of TGF-β2 can be effective in treating these cancer types.For example, in patients with pancreatic cancer, the overall survival time can be more than doubled, from 15 months for patients with high TGF-β2 to 37 months for patients with low TGF-β2.

[0086] The present invention includes a method for treating or ameliorating symptoms of cancer in a human or mammalian subject in need thereof by administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising an agent for inhibiting or suppressing the expression of TGF-β2 in combination with an additional anti-cancer agent, such as irinotecan or an agent containing irinotecan.

In the regimen, the active agents or their formulations may be administered contemporaneously, simultaneously, sequentially, or at different times. In some embodiments, the composition may be a pharmaceutical composition. In certain embodiments, the composition may be a pharmaceutical composition containing a therapeutically effective amount of one or more active compounds. Some examples of excipients are listed in Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pa. 1975, and Liberman, HA and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York, NY, 1980. Methods for determining a therapeutically effective amount of an agent are known in the art.

[0095] As used herein, the term kit containing "an agent comprising irinotecan" can refer to a kit comprised of active agents or formulations for use in a regimen.

[0096] Human TGF-β2-specific phosphorothioate antisense oligodeoxynucleotide agents Antisense oligonucleotides (ASOs) are single-stranded deoxyribonucleotides that can be complementary to mRNA targets. Antisense therapy can downregulate molecular targets by inducing RNase H endonuclease activity, which cleaves RNA-DNA heteroduplexes, resulting in a significant reduction in target gene translation. Other ASO mechanisms may include inhibition of 5' cap formation, alteration of splicing processes such as splice switching, and steric hindrance of ribosomal activity.

[0097] Antisense therapeutic strategies utilize single-stranded DNA oligonucleotides that inhibit protein production by mediating catalytic degradation of target mRNA or by binding to sites on mRNA required for translation. Antisense oligonucleotides can be designed to target viral RNA genomes or viral transcripts. Antisense oligonucleotides offer a potential therapeutic approach by providing an approach for identifying potential targets.

[0098] Antisense oligonucleotides can be small, synthetic fragments of single-stranded DNA that can be 15-30 nucleotides in length. ASOs specifically bind to complementary DNA / RNA sequences through Watson-Crick hybridization, and upon binding to the target RNA, they can inhibit the translation process either by inducing cleavage mechanisms or by inhibiting mRNA maturation. ASOs can selectively inhibit gene expression with specificity. Chemical modifications of DNA or RNA can be used to enhance stability.

[0099] For example, modifications can be introduced into phosphodiester bonds, sugar rings, and backbones. ASO antiviral agents can block the translation process either by (i) cleaving mRNA via ribonuclease H (RNAse H) or RNase P, or (ii) sterically (non-binding) blocking the enzymes involved in target gene translation. Human TGF-β2-specific phosphorothioate antisense oligodeoxynucleotides, such as OT-101, AP12009 travedelsen SEQ ID NO: 1, can be used to reduce the level of TGF-β2 protein in malignant tumors, thereby slowing disease progression.

[0100] Antisense oligodeoxynucleotides are short strands of DNA designed to downregulate gene expression by interfering with the translation of specific encoded proteins at the mRNA level. OT-101 is a synthetic 18-mer phosphorothioate oligodeoxynucleotide (S-ODN) in which all 3'-5' linkages are modified to phosphorothioates. The molecular formula is C 177 H 208 N 60 Na 17 O 94 P 17 S 17 and has a molecular weight of 6,143 g / mol. OT-101 was designed to be complementary to a specific sequence of human TGF-β2 mRNA following gene expression.

[0101] Antisense oligodeoxynucleotides are short strands of DNA designed to downregulate gene expression by interfering with the translation of specific encoded proteins at the mRNA level.For example, SEQ ID NO:1 (OT-101) is a synthetic 18-mer phosphorothioate oligodeoxynucleotide (S-ODN) in which the non-bridging oxygen of each phosphate moiety is replaced by a sulfur atom.OT-101 is complementary to a specific sequence of human TGF-β2 mRNA from gene expression.OT-101 can be an RNA therapeutic designed to neutralize the immunosuppressive effect of TGF-β2 and reduce the level of TGF-β2 in malignant tumors, so as to treat or improve cancer symptoms or delay the progression of disease.

[0102] The target TGF-β2 mRNA can be the NCBI reference sequence: NM_003238.3, which is 5,882 bp in length. The target region of the TGF-β2 mRNA can be the protein coding sequence from 1,369 to 2,613 of the reference.

[0103] Examples of agents of the present disclosure for inhibiting or suppressing the expression of TGF-β2 include the TGF-β2-specific antisense oligonucleotides set forth in Table 1, SEQ ID NOs: 1-136.

[0104] Table 1. TGF-β2-specific antisense oligonucleotides TIFF2026507184000002.tif29147TIFF2026507184000003.tif235147TIFF20265071840 00004.tif235147TIFF2026507184000005.tif235147TIFF2026507184000006.tif84147

[0105] The sequences in Table 1 can be chemically modified to provide active variants thereof, LNA variants thereof as well as gapmer variants thereof, as known in the art. The sequences in Table 1 can be used in any combination as an active agent, including as a pool combination.

[0106] It is understood that additional antisense oligonucleotides can be constructed based on the TGF-β2 gene sequence.

[0107] In some embodiments, the TGF-β2-specific antisense oligonucleotides of the present invention may have no more than one or no more than two mismatches compared to the target human TGF-β2.

[0108] In certain embodiments, the TGF-β2-specific antisense oligonucleotides of the invention may reduce the level of TGF-β2 transcript by at least 60%, or at least 70%, or at least 80%, or at least 90%.

[0117] Aspects of the invention that involve the administration or use of compositions of agents can ameliorate or suppress symptoms caused by TGF-β2-induced proteins.

[0118] As used herein, the term agent can refer to a single active agent or a composition of a single active agent with a carrier.

[0119] Embodiments of the present invention further include pharmaceutical compositions for inhibiting or suppressing the expression of TGF-β2 or for treating or ameliorating symptoms of cancer in humans or animals. The pharmaceutical composition may include a TGF-β2 inhibitor, artemisinin, a pharmaceutically acceptable salt form, ester, polymorph, or stereoisomer thereof, or any combination thereof, and a carrier.

[0124] For example, the API travedersen (OT-101) is a synthetic 18-mer S-ODN composed of the bases adenine (A), thymine (T), guanine (G), and cytosine (C), with all 3'-5' linkages modified to phosphorothioate. This sulfur modification makes the drug more resistant to degradation, resulting in improved stability in vitro and in vivo. Its primary molecular structure, the nucleotide sequence, was designed to be complementary to a specific sequence in human transforming growth factor beta 2 (TGF-β2) mRNA. This sequence and related sequences can be used due to their excellent chemical and structural properties, biological activity, and specificity to achieve the highest antisense efficacy in vitro and in vivo.

[0125] The chemical structure of travedersen, an example of the phosphorothioate moiety (CAG), and physical properties are shown in Table 2.

The kit may also contain suitable vials and all necessary components of an application system, i.e., syringes, tubing, and filters. The OT-101 lyophilized powder can be dissolved in isotonic (0.9%) aqueous sodium chloride solution before use.

[0129] Anticancer drug and therapeutic drug combinations Embodiments of the present invention include combinations of TGF-β2 inhibitors with anti-cancer agents such as irinotecan and formulations or regimens containing irinotecan.

[0130] Examples of irinotecan-containing formulations, agents, and / or regimens include FOLFIRINOX, NALIRIFOX, IRIFOX, and IRINOX. The dosage and time of administration of such irinotecan-containing formulations, agents, and / or regimens are known in the art.

[0131] The irinotecan-containing agents of the present disclosure can be formulated in various forms, such as small particle form, micelle form, hydrogel form, liposome form, or exosome form.

[0132] In certain embodiments, the present invention provides a therapeutic combination of one or more antisense TGF-β2 inhibitors and an agent containing irinotecan with a nanosized particle, nanosized micelle, nanosized hydrogel, nanosized liposome, or nanosized exosome.

[0133] Additional aspects of the present invention include therapeutic combinations of TGF-β2 inhibitors with FOLFIRINOX, NALIRIFOX, IRIFOX, or IRINOX agents in conjunction with standard of care therapy.

[0134] The unexpectedly beneficial synergistic effects of therapeutic combinations for cancer treatment of antisense TGF-β2 inhibitors and irinotecan-containing agents may be amplified if patients are selected based on biomarkers for clinical activity.

[0135] In the treatment of cancer patients, the therapeutic combination of the agent that contains irinotecan combined with antisense TGF-β2 inhibitor can significantly increase the overall survival time of patients.In some embodiments, the therapeutic combination of the agent that contains irinotecan with antisense TGF-β2 inhibitor can provide unexpectedly advantageous synergistic effect based on clinical data.

[0136] Synergistic effects of therapeutic combinations Embodiments of the present invention can provide a synergistic therapeutic combination of an agent for inhibiting or suppressing the expression of TGF-β2 and an agent containing a topoisomerase I inhibitor for treating or ameliorating symptoms of cancer.

[0137] Examples of irinotecan agents include irinotecan, irinotecan hydrochloride, irinotecan sucrose sulfate, and irinotecan sucrose sulfate forms.

[0138] Examples of topoisomerase I inhibitors include irinotecan, topotecan, rubitecan, and camptothecin derivatives and analogs such as 9-aminocamptothecin.

[0139] In some embodiments, the anti-cancer use of the combination of an antisense agent for inhibiting or suppressing the expression of TGF-β2 and an agent containing irinotecan can be particularly effective for patients with high levels of certain biomarkers, such as TGF-β2 in particular. Biomarkers can be used to select patients who will benefit from combination therapy.

[0140] Examples of regimens using irinotecan-containing agents include FOLFIRINOX, NALIRIFOX, IRIFOX, and IRINOX, as known in the art. For example, NALIRIFOX is liposomal irinotecan formulated with oxaliplatin, 5-fluorouracil, and leucovorin. For example, IRINOX is a combination of irinotecan formulated with oxaliplatin. For example, FOLFIRINOX is a combination of irinotecan hydrochloride formulated with leucovorin calcium (folinic acid), fluorouracil, and oxaliplatin. For example, FOLFIRI is a formulation of folinic acid (leucovorin, calcium folinate, or FA), fluorouracil (5FU), and irinotecan. For example, IRINOX is a formulation of irinotecan and oxaliplatin.

[0141] A drawback of conventional therapy using only irinotecan-containing agents is that not all cancer patients are suitable for such treatment. Irinotecan-containing agents can be used for cancer patients with low TGF-β2 levels, which indicate a low risk of progression. However, cancer patients with high TGF-β2 levels, which indicate a risk of progression, and / or other biomarker levels that suggest a risk of progression are typically treated only with palliative therapy, such as gemcitabine.

[0142] Embodiments of the present invention that combine an agent for inhibiting or suppressing TGF-β2 expression with an agent containing irinotecan may show the surprising advantage that overall survival and / or HRQoL may be improved for all cancer patients.

[0143] For example, embodiments of the invention utilizing a combination of a TGF-β2 inhibitor and an agent containing irinotecan can be used in cancer patients with low TGF-β2.

[0144] Additionally, embodiments of the present invention can be used in cancer patients with elevated TGF-β2 and / or other biomarker levels indicative of a risk of progression.

[0145] Therefore, the embodiment of the present invention that combines an antisense agent for inhibiting or suppressing the expression of TGF-β2 with an agent containing irinotecan can be used advantageously for all cancer patients.

[0146] Irinotecan-containing agents can be used against cancers including pancreatic cancer, colorectal cancer, gastric cancer, cervical cancer, lung cancer, melanoma, skin cancer, breast cancer, prostate cancer, kidney cancer, ovarian cancer, thymic cancer, and multiple myeloma.

[0149] All publications, including patents, published patent applications, and non-patent publications, as well as the sequence listing, referenced herein are each expressly incorporated herein by reference in their entirety for all purposes.

[0150] While the foregoing disclosure has been described in detail by way of example for purposes of clarity of understanding, it will be apparent to those skilled in the art that certain changes and modifications are encompassed by the present disclosure and can be made without undue experimentation within the scope of the appended claims, which are presented by way of example and not limitation. The present invention encompasses all such additional embodiments, equivalents, and modifications. The present invention includes any combination or mixture of the features, materials, elements, or limitations of the various exemplary components, examples, and claimed embodiments.

[0151] It is emphasized that, according to common practice, the features of the drawings are of any scale herein and are intended to cover similar features which may be enlarged or reduced at will. [Example]

[0152] Example 1 The disclosed methods and agents for suppressing TGF-β2 can be used for pancreatic cancer.

[0153] A clinical outcome study of patients with pancreatic cancer showed that decreased TGF-β2 expression was associated with improved overall survival (OS). This result was surprising because neither the TGF-β1 nor the TGF-β3 isoform was significantly associated with increased survival in pancreatic cancer. Therefore, this clinical study supports TGF-β2 as a sole therapeutic target in pancreatic cancer.

[0154] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer.

[0155] The results of the study on pancreatic cancer are shown in Figure 1. Figure 1 shows a highly significant (log-rank P=0.00515) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2. As understood in the art, a log-rank p-value of less than about 0.05 (or <0.1) confirms that the difference is significant. The improvement found in overall survival with reduced TGF-β2 expression was a significant increase from 16 months in the TGF-β2 high expression cohort to 37 months in the TGF-β2 low expression cohort.

[0156] The study in Figure 1 used quartile values ​​of TGFB2 expression from the Z-score of mRNA expression (log2 RSEM-UQ). Quartile statistics are shown in Table 3. Overall survival and other survival calculations are shown in Table 4.

[0159] Example 2. The disclosed methods and agents for suppressing TGF-β2 can be used for pancreatic cancer.

[0160] Clinical outcome studies on pancreatic cancer patients have been conducted and have shown improved overall survival (OS) with decreased TGF-β2 expression. Additional inclusion criteria: For this study, patients who had not received follow-up cancer therapy after surgery were selected.

[0161] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer.

[0162] The results of the pancreatic cancer study are shown in Figure 2, which shows a highly significant (log-rank P=0.0111) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2. The improvement in overall survival found with reduced TGF-β2 expression was a significant increase from 7 months in the high TGF-β2 expression cohort to at least 14 months in the low TGF-β2 expression cohort (B).

[0163] For the study in Figure 2, TGFB2 quartile values ​​from the z-scores of mRNA expression for all samples were used (log RNA Seq V2 RSEM). Quartile statistics are shown in Table 5. Overall survival and other survival calculations are shown in Table 6.

[0166] Example 3. Clinical outcome studies have been conducted on pancreatic cancer patients and have shown improved overall survival (OS) with reduced hypoxia, so patients can be selected based on hypoxia as a biomarker.

[0167] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced hypoxia in pancreatic cancer.

[0168] The results of the pancreatic cancer study are shown in Figure 3, which shows a highly significant (log-rank P=0.003126) improvement in overall survival for pancreatic cancer patients in whom hypoxia was reduced. The improvement found in overall survival with reduced hypoxia was a significant increase from 15 months in the high hypoxia cohort to 30 months in the low hypoxia cohort.

[0169] The study in Figure 3 used quartiles of the Buffa Hypoxia Score as a biomarker for patient selection. Quartile statistics are shown in Table 7. Overall survival and other survival calculations are shown in Table 8.

[0172] Example 4. Clinical outcome studies on pancreatic cancer patients have shown that a reduction in tumor mutation burden (TMB) is associated with improved overall survival (OS). Therefore, patients can be selected based on tumor mutation burden (TMB) as a biomarker.

[0173] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TMB in pancreatic cancer.

[0174] The results of the pancreatic cancer study are shown in Figure 4, which shows a highly significant (log-rank P=0.003013) improvement in overall survival for pancreatic cancer patients with reduced TMB. The improvement found in overall survival with reduced TMB was a significant increase from 16 months in the high TMB cohort to at least 22 months in the low TMB cohort (B).

[0175] The study in Figure 4 used quartiles of TMB (non-synonymous) as a biomarker to select patients. Quartile statistics are shown in Table 9. Overall survival and other survival calculations are shown in Table 10.

[0178] Example 5. The disclosed methods and agents for inhibiting TGF-β2 can be used for pancreatic cancer in combination with treatment with the agent irinotecan.

[0179] A clinical outcome study of patients with pancreatic cancer showed improved overall survival (OS) with reduced TGF-β2 expression, where patients were selected based on treatment with irinotecan. This result was surprising because improved OS with reduced TGF-β2 expression was not observed when patients were also treated with gemcitabine alone, fluorouracil alone, oxaliplatin alone, or leucovorin alone.

[0180] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer when patients were also treated with irinotecan.

[0181] The results of the pancreatic cancer study are shown in Figure 5, which shows a highly significant (log-rank P=0.0174) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2. The improvement found in overall survival with reduced TGF-β2 expression was a significant increase from 23 months in the high TGF-β2 expression cohort to a much longer period of 34 months in the low TGF-β2 expression cohort. The significant increase in overall survival indicates, among other things, that drug resistance effects are being avoided.

[0182] These results in Figure 5 demonstrate a surprising synergistic effect on increasing overall survival in treating pancreatic cancer using a therapy that combines reducing TGF-β2 expression with an agent containing irinotecan. These results were particularly surprising because none of oxaliplatin, leucovorin, or fluorouracil showed significant synergistic effects in combination with reducing TGF-β2 expression.

[0183] For the study in Figure 5, TGFB2 quartile values ​​from z-scores of mRNA expression for all samples were used (log RNA Seq V2 RSEM). Quartile statistics are shown in Table 11. Overall survival and other survival calculations are shown in Table 12.

[0186] Example 6 The disclosed methods and agents for inhibiting TGF-β2 can be used for pancreatic cancer in combination with treatment with the agent irinotecan.

[0187] Clinical outcome studies have been conducted on pancreatic cancer patients, showing improved overall survival (OS) with decreased TGF-β2 expression, where patients were selected based on treatment with irinotecan.

[0188] Patient survival was calculated using a Kaplan-Meier Plotter to determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer when patients were also treated with irinotecan.

[0189] The results of the pancreatic cancer study are shown in Figure 6, which shows a highly significant (log-rank P=0.0152) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2. The improvement found in overall survival with reduced TGF-β2 expression was a significant increase from 8 months in the high TGF-β2 expression cohort to at least 30 months in the lower TGF-β2 expression cohort (C). The significant increase in overall survival indicates, among other things, that drug resistance effects are avoided.

[0190] TGFB2 quartile values ​​from z-scores of mRNA expression for all samples were used in the study in Figure 6 (log RNA Seq V2 RSEM). Quartile statistics are shown in Table 13. Overall survival calculations are shown in Table 14.

[0193] Example 7 The disclosed methods and agents for inhibiting TGF-β2 can be used for pancreatic cancer in combination with treatment with the agent irinotecan.

[0194] Clinical outcome studies have been conducted on patients with pancreatic cancer, showing improved overall survival (OS) with decreased TGF-β2 expression, in which patients were selected based on treatment with irinotecan-containing FOLFIRINOX.

[0195] A Kaplan-Meier plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer when patients were also treated with irinotecan-containing FOLFIRINOX.

[0196] The results of the pancreatic cancer study are shown in Figure 7. Figure 7 shows a significant (log-rank P=0.0952) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2. The improvement found in overall survival with reduced TGF-β2 expression was a significant increase from 23 months in the high TGF-β2 expression cohort to at least 34 months in the lower TGF-β2 expression cohort (B). The significant increase in overall survival indicates, among other things, that drug resistance effects are avoided.

[0197] The study in Figure 7 used quartile values ​​of TGF-β2 from z-scores of mRNA expression for all samples (log RNA Seq V2 RSEM). Quartile statistics are shown in Table 15. Overall survival calculations are shown in Table 16.

[0198] Table 15. Quartile statistics of TGF-β2 for pancreatic cancer TIFF2026507184000020.tif44145

[0200] Example 8 The disclosed methods and agents for inhibiting TGF-β2 can be used for pancreatic cancer, where biomarkers can be used to select patients who will benefit from the agents.

[0201] Clinical outcome studies have been conducted on patients with pancreatic cancer, and have shown that reduced TGF-β2 expression is associated with improved overall survival (OS), using biomarkers to select patients who will benefit from the agent. Significant biomarkers for pancreatic cancer include reduced tumor mutation burden, reduced neoantigen load measured in the tumor microenvironment, reduced macrophages measured in the tumor microenvironment, reduced mesenchymal stem cells (MSCs) measured in the tumor microenvironment, and increased type 2 helper T cells (Th2) measured in the tumor microenvironment. Any combination of these biomarkers can also be used.

[0202] A Kaplan-Meier Plotter was used to calculate patient survival and determine the association between improved overall survival and reduced TGF-β2 expression in pancreatic cancer, where biomarkers were used to select patients who would benefit from the agent.

[0203] The results of the pancreatic cancer study are shown in Figure 8. Figure 8 shows a significant (log-rank P = 0.0025) improvement in overall survival for pancreatic cancer patients with reduced TGF-β2, where patients were selected using reduced macrophages measured in the tumor microenvironment. The improvement in overall survival observed with reduced TGF-β2 expression and reduced macrophages was a significant increase from 15 months in the high TGF-β2 expression cohort to 73 months in the low TGF-β2 expression cohort. This significant increase in overall survival indicates, among other things, that drug resistance effects are being avoided.

[0204] Similar results were obtained with p-values ​​for additional biomarkers as follows: reduced tumor mutational burden (log-rank P = 0.079), reduced neoantigen burden measured in the tumor microenvironment (log-rank P = 0.051); Decreased mesenchymal stem cells (MSCs) measured in the tumor microenvironment (log-rank P=0.031); Increased type 2 helper T cells (Th2) measured in the tumor microenvironment (log-rank P = 0.025); The combination of reduced tumor mutational burden and reduced M0 macrophages (log-rank P=0.0018), and A combination of reduced neoantigen load measured in the tumor microenvironment and reduced M0 macrophages (see Figure 9, log-rank P=0.000076).
