Abstract
Description
Screening methods for oncolytic virus therapy patients Technical Field
[0001] This application relates to the field of biomedicine, specifically to a method for screening oncolytic virus treatment populations. Background Technology
[0002] Oncolytic viruses (OVs) are a novel cancer treatment approach. They are a class of natural or recombinant viruses that selectively infect and kill tumor cells without harming normal cells. Unlike traditional chemotherapy and radiotherapy, oncolytic virus therapy has several advantages, including good targeting, fewer adverse reactions, multiple tumor-killing pathways, and low likelihood of developing drug resistance. However, the different tumor types, stages, and heterogeneity pose challenges in selecting suitable patients for OV treatment. Furthermore, patients undergoing oncolytic virus clinical trials often have previously received multiple conventional treatments, which may lead to a weakened immune system and potentially fundamentally altered tumor cells.
[0003] The "Technical Guidelines for the Application of Biomarkers in the Clinical Development of Antitumor Drugs" states that "in the early stages of clinical trials, the use of appropriate biomarkers for exploratory research is encouraged to obtain more information on the effects of drugs on the human body, including pharmacodynamic and toxic effects. Through prospective or retrospective studies on the correlation between biomarkers and clinical outcomes, the efficacy prediction or prognostic value of biomarkers can be explored, providing preliminary basis for the selection of key clinical trial populations, stratification factors, and safety risk control."
[0004] Therefore, an oncolytic virus screening strategy is needed to select suitable patients through specific predictive biomarkers, detect the immune response of patients receiving active treatment, and determine which patients can clinically benefit from oncolytic virus therapy. This would help to maximize treatment efficacy and improve the quality of clinical research.

The antigen processing protein may include, but is not limited to, proteasome subunit β family proteins (PSMB) and TAPBPL, such as PSMB8, PSMB9, or PSMB10. The term "antigen transporter" refers to a protein that can participate in the modification and presentation of endogenous antigenic peptides, usually located on the endoplasmic reticulum, enabling it to bind to MHC class I molecules to form MHC I-antigen peptide complexes, which are then presented to the cell surface for recognition by T cells, generating a specific immune response. The antigen transporter includes, but is not limited to, endoplasmic reticulum aminopeptidase (ERAP) and antigen processing-associated transporters (TAP), such as ERAP1, ERAP2, TAP1, and TAP2.

[0195] Invention Details
[0196] On the one hand, this disclosure provides a method for screening a patient population for oncolytic virus therapy, the method comprising: detecting the patient's HLA typing, detecting antigen expression in tumor cells and / or detecting the integrity of antigen presentation pathways.
[0197] HLA
[0198] In antigen-presenting cells (APCs), protein antigens are processed into peptides. These peptides bind to HLA and are presented as peptide-HLA complexes to the cell surface of T cells. Different individuals express different HLA molecules, and different HLA molecules present different peptides. Therefore, according to the prior art, if a peptide or fragment of a larger polypeptide is presented by an HLA molecule expressed by a subject, it is identified as immunogenic to that specific human subject. In other words, the prior art describes immunogenic peptides as HLA-restricted epitopes. However, HLA-restricted epitopes induce T cell responses only in a subset of individuals expressing HLA molecules. Despite HLA allele matching, a peptide that activates a T cell response in one individual may be inactive in others. Therefore, it is unknown how an individual's HLA molecules present antigen-derived epitopes that positively activate a T cell response.
[0199] HLA is encoded by most polymorphic genes in the human genome. Each person possesses three HLA class I molecules (HLA-A*, HLA-B*, HLA-C*) and four HLA class II molecules (HLA-DP*, HLA-DQ*, HLA-DRB1*, HLA-DRB3* / 4* / 5*), which present different epitopes from the same protein antigen. The function of HLA molecules is to regulate T cell responses. However, how human HLA regulates T cell activation remains unknown.
[0200] The nomenclature used to represent the amino acid sequence of an HLA molecule is as follows: Gene Name * Allele: Protein Number, for example, it could look like: HLA-A*02:25. In this example, "02" refers to the allele. In this application, it can also be written as HLA-A02 or HLA-A2. In most cases, the allele is defined by serotype C, meaning that proteins of a given allele will not react with each other in serological assays. Protein numbers are assigned sequentially upon protein discovery. Any protein with a different amino acid sequence is assigned a new protein number (e.g., even a change in one amino acid in the sequence is considered a different protein number). Further information about the nucleic acid sequence of a given locus can be appended to the HLA nomenclature, but such information is not required for the methods described herein.
[0201] The mouse major histocompatibility complex (MHC) and the human MHC (HLA) share a high degree of structural and functional similarity. Immunologically, both activate T cells by recognizing and presenting antigen fragments. Structurally, MHC molecules consist of heavy and light chains forming antigen-binding grooves for loading and presenting antigen fragments to T cells. Regarding antigen presentation mechanisms, MHC molecules participate in antigen presentation in both humans and mice. Class I molecules are responsible for presenting intracellular pathogen antigen fragments, while class II molecules primarily present extracellular antigens; this mechanism is conserved across species. The properties of MHC genes are also highly similar. The MHC gene complex consists of multiple closely adjacent gene loci whose encoded products have the same or similar functions. This polymorphism and polygenicity are present in both the mouse MHC (H-2 complex) and the human HLA system.
[0202] According to the embodiments provided in this application, oncolytic viruses promote the presentation function of HLA and significantly enhance tumor-specific T cell responses. Therefore, when a patient is found to have a specific HLA that matches the tumor antigen, the administration of oncolytic viruses can promote its antigen presentation function, thereby enhancing the immune response.
[0203] Tumor antigens
[0204] Based on the examples provided in this application, oncolytic viruses can activate HLA to present tumor antigens, thereby activating tumor-specific T cell responses. Therefore, the tumor antigens described in this application include any tumor antigens currently known.
[0205] In one embodiment, the tumor is a solid tumor.
[0206] In one embodiment, the tumor includes soft tissue sarcoma, head and neck tumors, skin cancer, melanoma, liver cancer, gastric cancer, gynecological and / or genital tumors.
[0207] In one embodiment, the tumor includes synovial sarcoma, myxosarcoma, liposarcoma, adenoid cystic carcinoma, thymic carcinoma, oropharyngeal carcinoma, head and neck squamous cell carcinoma, skin cancer, malignant melanoma, cervical cancer, vulvar cancer, vaginal cancer, penile cancer, hepatocellular carcinoma, and / or gastric cancer.
[0208] The tumor antigens described in this application can be presented by HLA, including but not limited to the following tumor antigens:
[0209] A)NY-ESO-1
[0210] NY-ESO-1 (New York Esophageal Squamous Cell Carcinoma 1) is an antigen expressed in various tumors and belongs to the cancer testis antigen family. It is an important target in tumor immunotherapy because it is immunogenic and can induce an immune response in the body.
[0211] NY-ESO-1 can be presented by multiple HLA alleles, among which the HLA-A2 allele is the most studied. Certain peptides of NY-ESO-1, especially the NY-ESO-1(157-165) peptide, are HLA-A02 epitopes with immunogenicity and strong immunogenicity. This means that the NY-ESO-1(157-165) peptide can be presented to T cells by HLA-A02 molecules, thereby activating an immune response against tumor cells expressing NY-ESO-1 (Liu Jingwei et al., Journal of Peking University (Health Sciences), 2017, 49(5):840-846.).
[0212] Besides HLA-A2, there are other restrictive HLA alleles for the NY-ESO-1 antigen. For example, HLA-A11 is also a restrictive allele of NY-ESO-1. Wang Jie et al. (Abstracts of the 13th National Congress of Immunology, 2018) screened for HLA-A11 restrictive epitopes of the NY-ESO-1 antigen in order to provide more options for NY-ESO-1 antigen-based tumor cell therapy.
[0213] Studies by Jager E et al. have shown that NY-ESO-1 can be presented by the HLA-B51 allele and can activate CD8+ T cell responses (Cancer Immun, 2002, 19(2):12.). Furthermore, other studies have shown that NY-ESO-1 can be presented by the HLA-DRB4 allele and can activate CD4+ T cell responses. This indicates that NY-ESO-1 can activate CD8+ T cells not only through the HLA-A02 allele but also through the HLA-DRB4 allele, thereby enhancing the body's immune response. (Jager E et al., J Exp Med, 2000, 191(4):625-630.)
[0214] In summary, NY-ESO-1 can be presented through multiple HLA alleles, including but not limited to HLA-A02, HLA-A11, HLA-A24, HLA-A31, HLA-A68, HLA-B07, HLA-B35, HLA-B51, HLA-B52, and HLA-C12, which makes it a promising candidate for tumor immunotherapy.
[0215] B)MAGE-A4
[0216] MAGE-A4 (melanoma-associated antigen A4) is a tumor antigen expressed in a variety of solid tumors and belongs to the MAGE protein family. In normal tissues, MAGE-A4 is usually expressed only in immune-exempt sites such as the testes, but it is expressed in a variety of tumors, such as synovial sarcoma, non-small cell lung cancer, head and neck squamous cell carcinoma, ovarian cancer, urothelial carcinoma, melanoma, and gastroesophageal cancer.
[0217] MAGE-A4 antigen can be broken down into multiple antigenic peptides that can be presented by HLA molecules and activate specific T cell responses. In tumor immunotherapy, several HLA-A02-restricted MAGE-A4 antigenic peptides have been identified that can activate CD8+ T cells, thereby producing a killing effect on tumor cells. For example, MAGE-A4102-130 (MLP-1), MAGE-A4134-160 (MLP-2), MAGE-A4230-239 peptide antigenic epitopes GVYDGREHTV, and MAGE-A4274-306 (MLP-3) are potential long peptides targeting the MAGE-A4 antigen. They have shown strong immunogenicity in in vitro experiments and can activate T cells (Lanqi Cen et al., Cancer Cell International, volume 24, Article number: 232 (2024)).
[0218] In addition, MAGE-A4 is not only presented by HLA-A02, but can also be presented by HLA-A01 and HLA-A24 alleles, and can activate the corresponding T cell response (Akiyama Y et al., Cancer Immunol Immunother, 2012, 61(12):2311-2319.).
[0219] C)PRAME
[0220] PRAME (preferentially expressed antigen in melanoma) is a tumor-associated antigen expressed in a variety of tumors, but its expression level is low or absent in healthy tissues, making it an attractive target for immunotherapy. PRAME can be presented by a variety of HLA-A1 alleles, including but not limited to HLA-A*02:01, HLA-A*01:01, HLA-A*03:01, HLA-A*24:02, and HLA-A*11:01 (Richard Addo et al., Blood, 2020, 136 (Supplement 1)).
[0221] D)MART-1
[0222] MART-1 (melanoma antigen 1) is a tumor-associated antigen expressed in melanoma and several other tumor types. It is an important target for immunotherapy because it can be presented by specific HLA alleles, thereby activating the T-cell immune response against tumor cells.
[0223] MART-1 can be presented by the HLA-A02 (HLA-A*0201) allele. In one study, clinical benefits have been observed in some patients by adoptive transfer of lymphocytes expressing high-affinity T-cell receptors (TCRs) that specifically target the MART-1 27-35 / HLA-A*0201 complex. This suggests that specific peptides of MART-1 (such as the 27-35 peptide) can bind to the HLA-A*0201 molecule and form peptide-MHC complexes on the surface of melanoma cells. These complexes can be recognized by T-cell receptors and activate T cells to kill tumor cells (Ali R. Jazirehi et al., Cancer Res (2011) 71(4):1406–1417.).
[0224] In addition, MART-1 can bind to other HLA alleles, such as, but not limited to, HLA-A03 (HLA-A*0301), HLA-A11, HLA-A24, HLA-A32, HLA-A68, HLA-B07, HLA-B35, and HLA-B45, to present different MART-1 peptides.
[0225] E)gp100
[0226] gp100 (melanoma-associated antigen) is a lineage antigen expressed in melanocytes and melanomas. It can be presented to T cells via specific HLA alleles, thereby activating an immune response against tumor cells. gp100 can be presented by the HLA-A02 (HLA-A*02:01) allele (Chen Yuan et al., Abstracts of the 14th National Congress of Immunology, 2021). In addition, gp100 can bind to other HLA alleles, including but not limited to HLA-A03 (HLA-A*0301), HLA-A11, HLA-A24, HLA-A32, HLA-A68, HLA-B07, HLA-B35, and HLA-B45, presenting different MART-1 peptides.
[0227] F)HPV E6 / E7
[0228] HPV (human papillomavirus) E6 and E7 proteins are viral proteins closely related to the development of malignant tumors such as cervical cancer. They promote malignant transformation of cells by interfering with cell cycle regulation. E6 and E7 proteins can be presented by various HLA alleles, thereby activating specific T-cell immune responses. HPV E6 and E7 proteins can be presented by HLA-A2 and HLA-A11 alleles, resulting in a strong HLA-A2 and HLA-A11-restricted HPV18E7-specific CD8+ T-cell immune response (Shiwen Peng et al., Journal of Biomedical Science, volume 29, Article number: 80 (2022)). HPV E6 / E7 proteins can also be presented by HLA class II molecules, such as HLA-DRB1 (DRB1 09:01).
[0229] G)HBsAg
[0230] Hepatitis B surface antigen (HBsAg) is a hepatitis B virus (HBV) surface antigen. It can be degraded into polypeptide fragments by the proteasome, which then bind to HLA molecules and are ultimately presented to CD8+ T cells. HBsAg also regulates cell production and influences the reconstruction of the host immune system through direct interaction with human monocytes and macrophages via HLA molecule presentation. It can be presented by HLA-A02 typing, including but not limited to A02:01, A02:03, and A02:07.
[0231] H)EBV
[0232] EBV antigens are antigens produced by host cells after infection with Epstein-Barr virus. Most infected individuals retain EBV throughout their lives, and problems are generally rare. However, in certain cases, EBV is associated with the development of some cancers, including Burkitt's lymphoma, Hodgkin's lymphoma, EBV-positive post-transplant lymphoproliferative disease (PTLD), gastric cancer, and nasopharyngeal carcinoma. For example, LMP1 and LMP2 are latent membrane proteins of EBV and are expressed by most nasopharyngeal carcinoma cells (Nancy Raab-Traub, Semin Cancer Biol, 2002, 12(6):431-441). EBV antigens can be presented to T cells by HLA class I molecules, thereby triggering an EBV-specific T cell response. HLA class I molecules include, but are not limited to, HLA-A02, HLA-A11 (HLA-A11:01), and HLA-A31 (HLA-A31:01).
[0233] Based on existing research on tumor antigens and their corresponding restrictive HLA types, and the experimentally demonstrated principle that oncolytic viruses can promote HLA presentation, this indicates that any tumor antigen capable of HLA presentation can have its presentation function enhanced through oncolytic virus treatment, thereby strengthening tumor-specific T-cell responses. Therefore, any known HLA-presentable tumor antigen is applicable to this application.
[0234] Antigen presentation pathway integrity
[0235] Antigen presentation is a crucial process by which the immune system recognizes and responds to endogenous and exogenous antigens (such as viral antigens or tumor antigens). This process involves multiple steps, including antigen uptake, processing, peptide synthesis, peptide binding to MHC molecules, and finally, presentation to T cells on the cell surface. Therefore, the integrity of the antigen presentation pathway affects HLA-presented antigens. This application demonstrates pathway integrity by detecting the expression of key genes / proteins in the antigen presentation pathway.
[0236] In the process of antigen presentation, genes / proteins such as TAPBP (Tapasin), PSMB8, PSMB9, PSMB10, ERAP1 (Endoplasmic Reticulum Aminopeptidase 1), ERAP2 (Endoplasmic Reticulum Aminopeptidase 2), TAP1 (Transporter associated with antigen processing 1), and TAP2 (Transporter associated with antigen processing 2) all play crucial roles. They are indispensable in ensuring that antigens can be effectively processed by cells and presented to T cells.
[0237] TAP1 and TAP2 are key transport proteins in antigen processing and presentation. They form heterodimers responsible for transporting cytoplasmic peptides to the endoplasmic reticulum (ER) so that these peptides can bind to MHC class I molecules. TAPs are essential for maintaining the stability of MHC class I molecules and presenting antigen peptides to CD8+ T cells. TAPBPL is a molecular chaperone in the ER that facilitates the binding of MHC class I molecules to antigen peptides and is crucial for the proper folding and stable expression of MHC class I molecules on the cell surface. PSMB8, PSMB9, and PSMB10 are catalytic subunits of the immunoproteasome. Under the induction of cytokines such as interferon-γ (IFN-γ), they replace the corresponding subunits in the standard proteasome to form the immunoproteasome. The immunoproteasome is more efficient in processing antigen peptides, generating peptides more suitable for binding to MHC class I molecules, thereby enhancing antigen presentation. ERAP1 and ERAP2 are endoplasmic reticulum aminopeptidases that are responsible for pruning the N-terminal amino acids of antigenic peptides to ensure that the peptide length and sequence are suitable for the binding groove of MHC class I molecules.
[0238] Dysfunction or loss of these proteins can lead to reduced antigen presentation efficiency, affecting T cell recognition of antigens and thus weakening the body's immune response. For example, loss of function of TAP1 and TAP2 can result in reduced expression of MHC class I molecules, interfering with the formation of cytotoxic T lymphocytes and affecting immune responses to certain pathogens (Ian Mantel et al., Nature reviews. Clinical oncology, 2022 Jan 11.). Therefore, these proteins are indispensable in antigen presentation pathways.
[0239] Oncolytic virus
[0240] According to the embodiments provided in this application, regardless of the type of oncolytic virus used or whether the oncolytic virus is genetically modified, it will promote the HLA presentation function. Therefore, the oncolytic virus used in this application can be any known oncolytic virus, such as including but not limited to adenovirus (AdV), herpes simplex virus (HSV), Newcastle disease virus (NDV), measles virus (MV), vesicular stomatitis virus (VSV), poliovirus, Coxsackie virus, reovirus and vaccinia virus (VV).
[0241] In one embodiment, the oncolytic virus of this application can also be used in combination with an immune checkpoint inhibitor, such as a PD-L1 / PD-L2 inhibitor. In one embodiment, the oncolytic virus of this application can be used in combination with a PD-1 antibody, wherein the PD-1 antibody can be any known PD-1 antibody. The combination can be administered simultaneously with an immune checkpoint inhibitor or separately from the immune checkpoint inhibitor.

[0249] In one embodiment, this application detects antigen presentation pathway proteins by gene sequencing.

[0329] Example
[0330] Example 1: Clinical Screening Strategy
[0331] Blood and tumor tissue samples were collected from the patient. Based on the patient's indication, HLA typing, antigen presentation, and tumor cell expression antigen biomarkers were tested according to Table 1. If all three results met the requirements, the patient was successfully screened and belonged to the oncolytic virus treatment population.
[0332] Table 1. Screening biomarkers for oncolytic virus indications
[0333] Example 1.1 HLA typing detection method
[0334] HLA testing methods can be any known testing method in the field, including but not limited to polymerase chain reaction-sequence-specific primers (PCR-SSP), polymerase chain reaction-sequence-specific oligonucleotide hybridization (PCR-SSO), sequence-based genotyping (SBT), restriction fragment length polymorphism analysis (PCR-RFLP), polymerase chain reaction single-strand conformation polymorphism analysis (PCR-SSCP), specific primer PCR technology (PCR-SSP), liquid phase DNA probe hybridization capture technology, next-generation gene sequencing methods, and Luminex screening.
[0335] Description of the method for detecting antigen-presenting pathway protein genes using next-generation sequencing: Blood is collected from the patient, DNA is extracted, PCR amplification is performed, sequencing is conducted, and data analysis is performed.
[0336] Example 1.2 Method for detecting tumor cell expression antigens
[0337] The detection method for tumor antigens can be any known detection method in the field, including but not limited to whole exome sequencing (WES), RNA sequencing (RNA-seq), mass spectrometry, immunohistochemistry (IHC), flow cytometry, ELISPOT (enzyme-linked immunospot assay), TCR sequencing, NEST technology platform, SABAs system, Presenter system, RootPath system and MHTEM system.
[0338] Description of the method for detecting tumor antigen expression using immunohistochemistry: Tumor tissue from the patient is collected, paraffin sections are prepared, and immunohistochemical staining is performed on a fully automated immunohistochemical analyzer using MAGE-A4 antibody, PRAME antibody, NY-ESO-1 antibody, HPV E6 / E7 antibody, MART-1 antibody, gp100 antibody, HBsAg antibody, and / or EBV antibody. The quality of the stained sections will be reviewed; unsatisfactory stained sections will be re-stained according to the pathologist's assessment. Results for acceptable stained sections are interpreted and recorded.
[0339] Example 1.3 Method for detecting the integrity of antigen presentation pathway
[0340] The detection method for antigen presentation pathway proteins can be any known detection method in the art, including but not limited to Western blotting (WB), immunohistochemistry (IHC), enzyme-linked immunosorbent assay (ELISA), flow cytometry, mass spectrometry, pMHC multimer staining, gene sequencing, and detection of abnormal glycan glycoproteins (TAP).
[0341] Description of the method for detecting antigen-presenting pathway protein genes using next-generation sequencing: Blood is collected from the patient, DNA is extracted, PCR amplification is performed, sequencing is conducted, and data analysis is performed.
[0342] Example 2: Validating the HLA screening strategy based on a mouse bladder cancer model
[0343] A cell line expressing the OVA antigen, MB49-OVA, was established using mouse bladder cancer cells MB49 (Dr. Longcheng Li, Laboratory of Molecular Medicine, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing 100730, China). MB49-OVA tumors were then established in C57BL / 6 mice. When the tumor volume reached 100 mm^3, intratumoral injection of KM1 was performed. KM1 is a recombinant vaccinia virus developed by Shenzhen Huayao Kangming Biopharmaceutical Co., Ltd., which uses Listeria vaccinia virus strain as a vector for genomic modification, deleting the TK, L025, and A46R genes and inserting the 4-1BBL and IL-21 genes. It is deposited at the China Center for Type Culture Collection (CCTCC) with accession number V201938, dated July 4, 2019; the strain name is genetically modified Listeria genotype vaccinia virus KM1, and the depositor is Shenzhen Huayao Kangming Biopharmaceutical Co., Ltd. Limited Liability Company (Applicant). Ten days after KM1 injection, mice were sacrificed, and spleen cells were isolated. Mouse spleen cells were cultured in 96-well plates, and the antigenic peptide OVA (257-264) (SIINFEKL) (Sangon Biotech (Shanghai) Co., Ltd.) was added during the culture process. IFN-γ was measured in the cell culture medium after 48 hours. The results are shown in Figure 1. After adding OVA257-264, the IFN-γ secretion level of spleen cells in the MB49-OVA+KM1 group was significantly increased (approximately 3-fold) compared to the MB49-OVA group; compared to the MB49-OVA+KM1 group without the antigenic peptide, the IFN-γ secretion level increased nearly 7-fold after adding the antigenic peptide. These results indicate that the oncolytic virus effectively promoted a specific T-cell response to the MHC H2b-presented OVA257-264 antigenic peptide (SIINFEKL).
[0344] Example 3: Validating the HLA screening strategy based on a mouse melanoma model
[0345] A cell line expressing the endogenous tumor antigen Trp2 was established using mouse melanoma cells B16F10 (Shanghai Jiao Tong University School of Medicine). B16F10 tumors were then created in C57BL / 6 mice. When the tumor volume reached 100 mm³, KM1 was injected intratumorally. Ten days after KM1 injection, mice were sacrificed, and spleen cells were isolated. Mouse spleen cells were cultured in 96-well plates, with the Trp2 antigen peptide Trp2(180-188) (SVYDFFVWL) (Sangon Biotech (Shanghai) Co., Ltd.) added during the culture process. After 48 hours, the cell culture medium was collected to measure IFN-γ. As shown in Figure 2, after the addition of Trp2 (180-188), the IFN-γ secretion level of spleen cells in the B16F10+KM1 group was significantly increased compared to the B16F10 group. These results indicate that the oncolytic virus effectively promotes the specific T cell response against Trp2 180-188 (SVYDFFVWL) presented by MHC H2b. In Figure 3, the spleen volume of the animals in the KM1 group was larger than that in the PBS group, indicating that KM1 can effectively activate the immune response, causing immune cell proliferation and resulting in spleen enlargement.
