EXAMPLES
Example 1: Design of the Antigenic Unit Comprised in The Polynucleotide/Polypeptide/Dimeric Protein and Vaccine of the Invention
[0286] The antigenic unit may be designed with the following variations in the patient-present shared antigen sequence: [0287] A. Full-length sequence [0288] B. HLA-optimized sequences. The selected sequence for inclusion into the antigenic unit is optimized to cover the most immunogenic epitopes, i.e. those having a high binding affinity to the patient’s HLA I and/or HLA II molecules [0289] C. Epitopes with predicted binding to the patient’s HLA I and/or HLA II molecules. [0290] D. Combination of A+C [0291] E. Combination of B+C [0292] F. Combination of A+B
[0293] The patient-present shared antigen sequence above may for instance be HPV16. In cases D and F, which include a full-length sequence, case D may for instance be the combination of HPV16 E7 as a full-length sequence (A) and epitopes from HPV E6 (C) while case F may for instance be the combination of HPV16 E7 as a full-length sequence (A) and HLA-optimized sequences (B). The aforementioned example includes one single patient-present shared antigen but two different regions thereof. In another embodiment, cases D and F relate to the combination of the full-length sequence (A) of a first patient-present shared antigen, e.g. HPV16 E7 and epitopes (C) or HLA-optimized sequences (B) of a second patient-shared antigen, e.g. KRAS.
[0294] Thus, the antigenic unit may comprise A-F from one patient-present shared antigen or comprise A-F from several patient-present shared antigens.
[0295] Sequences A-F are arranged in the antigenic unit according to the methods provided herein. Different antigenic unit designs may be evaluated in animal models, e.g. as described in Example 3 to determine the optimal antigenic unit design. Breadth, strength and kinetics for the antigen-specific immunogenicity can be determined by IFN-gamma ELISPOT analysis. Anti-tumor efficacy can be tested in a tumor challenge experiment.
Example 2: Construction of a Polynucleotide According to the Invention
[0296] A polynucleotide according to the invention is designed and comprises the following units and components:
TABLE-US-00001 1: Native leader sequence for human LD78b Signal peptide 2: Full-length LD78b sequence Targeting unit 3: Human hinge-region 1 from IgG3 Dimerization unit 4: Human hinge region 4 from IgG3 5: Glycine-Serine linker 6: Human CH3 domain from IgG3 7: Glycine-Leucine linker Unit linker 8: Patient-present shared antigen sequence(s) Antigenic unit 9: Optionally: patient-specific antigen sequence(s)
EXAMPLE 3: Selecting Sequences of Patient-Present Shared Antigens for Inclusion Into the Antigenic Unit Comprised in the Polynucleotides/Polypeptides/Dimeric Peptides and Vaccines According to the Invention
[0297] Blood samples and tumor tissue samples of two patients — patient 1 and 2 — presenting with squamous cell carcinoma of the head and neck were obtained. The blood sample was analyzed for exome sequencing to characterize the exons in the healthy cells. The tumor tissue sample was analyzed for exome sequencing to characterize the exons in the tumor tissue and RNA-seq to evaluate RNA expression level of each gene. The presence of HPV16 shared antigen was identified using anti-HPV16 antibodies in an ELISA.
[0298] To find the most immunogenic sequences, each patients HLA class I and II alleles were determined by sequencing normal tissue (blood cells). The following HLA class I and II alleles were found:
TABLE-US-00002 Patient 1 - HLA class I alleles Patient 1 - HLA class II alleles HLA-A01:01 DRB1_0701 HLA-A24:02 DRB1_1301 HLA-B08:01 DRB3_0202 HLA-B40:01 DRB4_0101 HLA-C03:04 HLA-DQA10103-DQB10202 HLA-C07:01 HLA-DQA10103-DQB10603 HLA-DQA10201-DQB10202 HLA-DQA10201-DQB10603 HLA-A01:01 DRB1_0101 HLA-A24:02 DRB1_1301 HLA-B40:01 DRB3_0202 HLA-C03:04 HLA-DPA10103-DPB10401 HLA-DQA10101-DQB10501 HLA-DQA10101-DQB10603 HLA-DQA10103-DQB10501 HLA-DQA10103-DQB10603
[0299] HPVs have circular, double-stranded DNA genomes that are approximately 8 kb in size and encode eight genes, of which E6 and E7 have transforming properties. The viral E6 and E7 proteins are known to be involved in conversion of healthy cells into malignant cells. The abilities of HPV16 E6 and E7 proteins to associate with the tumor suppressors p53 and pRB, respectively, have been suggested as a mechanism by which these viral proteins induce tumors. Thus, the E6 and E7 sequences of HPV16 are known shared tumor antigens and were selected for finding sequences therein for inclusion into the antigenic unit. Prediction of binding to the patients’ HLA class I and HLA class II alleles was carried out using the NetMHCpan 4.0 software.

[0326] Comparing patient 1 and 2, i.e.
Example 4: Comparing Vaccines Comprising Patient-Specific Antigens and Patient-Present Shared Antigens
[0327] To compare the efficacy of vaccines comprising only patient-specific antigen sequences with vaccines according to the invention comprising patient-present shared antigen sequences and optionally patient-specific antigen sequences, a mouse TC-2 tumor model is used.
[0328] Shared antigens and specific antigens present in the TC-2 tumor cell line are identified, processed and selected as described herein, i.e. shared antigen sequences for inclusion into the antigenic unit are selected based on their binding to MHC molecules while specific antigen sequences are selected based on additional parameters in an in silico predicted immunogenicity method. The shared antigen which is selected for inclusion into the antigenic unit is the viral antigen HPV16 and sequences encoding parts of the E6 and E7 proteins thereof were selected.
[0329] All selected antigen sequences are ordered from a commercial supplier, e.g. from Genscript (New Jersey, US) and cloned into the expression vector pUMVC4a, which comprises sequences encoding the LD78beta targeting unit and the hlgG3 dimerization unit.
[0330] The antigenic unit of vector 1 only comprises shared antigen sequences while the antigenic unit of vector 2 comprises both shared antigen sequences and specific antigen sequences.
[0331] To verify correct vaccibody formation, HEK293 cells are transfected with the vectors and vaccibody proteins in the supernatant are identified by Western blot and/or sandwich ELISA. The empty pUMVC4a vector is included as a negative control. Intact homodimeric protein formation is confirmed as follows: the proteins in the supernatant from transfected cells are detected in a Western blot by an anti-hMIP-1alpha antibody, in either the presence of reducing agents, which result in dimeric proteins being reduced to monomers, or absence of reducing agents.
[0332] A vaccine is prepared by mixing 20 .Math.g of the vector 1 and 2, respectively, with an aqueous buffer. The vaccine is injected intramuscularly in the tibial anterior muscle of the mouse followed by electroporation using TriGrid, Ichor, (US). At day 13, the mice are euthanized, and spleens are harvested.
[0333] The T cell responses are evaluated by IFN-gamma ELISpot. We observe that vaccines according to the present invention induce broader T cell responses that are higher compared to vaccines comprising only specific antigen sequences.
Example 5: Individual Therapeutic Anticancer DNA Vaccine According to the Invention
[0334] An individual therapeutic anticancer DNA vaccine according to the invention may be prepared by GMP manufacturing of the vector comprising the polynucleotide according to the invention according to regulatory authorities’ guidelines, and Fill & Finish of the DNA vaccine. The vector may be formulated by dissolving it in a sterile saline solution, such as PBS, at a concentration of 2-6 mg/ml. The vaccine may be administered either intradermally or intramuscularly with or without following electroporation or may alternatively be administered with a jet injector.
Example 6: Selecting Sequences of Patient-present Shared Antigens (and Patient-Specific Antigens) for Inclusion Into the Antigenic Unit Comprised in the Polynucleotides/Polypeptides/Dimeric Peptides and Vaccines According to the Invention
[0335] Blood samples and tumor tissue samples of three patients (patient 1, 2 and 3) presenting with squamous cell carcinoma of the head and neck were obtained. The blood sample was analyzed for exome sequencing to characterize the exons in the healthy cells. The tumor tissue sample was analyzed for exome sequencing to characterize the exons in the tumor tissue and RNA-seq to evaluate RNA expression level of each gene.
[0336] The presence of HPV16 shared antigen was identified using PCR. The ectopic expression of NY-ESO-1 was determined by anti-NY-ESO-1 antibodies in an ELISA. Patient-specific antigen sequences for each patient were identified as previously described in this application and in WO 2017/118695, which is included herein by reference.
[0337] NY-ESO-1 (also known as cancer/testis antigen 1B) is a protein belonging to the family of cancer-testis antigens (CTAs) that have been found to be re-expressed in a variety of malignant tumors at the mRNA and protein levels, while its normal expression in adult tissue is restricted to germ cells and placental cells. NY-ESO-1 expression has been reported in a wide range of tumor types.
[0338] For HPV, the E6 and E7 sequences of HPV16 are known shared tumor antigens and were selected for finding sequences therein for inclusion into the antigenic unit.
[0339] To find the most immunogenic sequences, each patients HLA class I and II alleles were determined by sequencing normal tissue (blood cells). Prediction of binding of HPV16 E6/E7 sequences and NY-ESO-1 sequences to the patients’ HLA class I and HLA class II alleles was carried out using the NetMHCpan 4.0 software. Included in the analysis were sequences from the IEDB database which are known from the literature to have elicited a positive T cell response (not matched to patients’ HLA alleles).
[0340] The HLA class I and II alleles which were found for patients 1, 2 and 3 are listed in the table below:

Example 7: Immunogenicity of DNA Vaccines According to the Invention
Design of DNA Vaccines Comprising Shared Antigen Sequences And/or Neoepitopes
[0353] Five DNA vaccines (constructs) were designed comprising nucleotide sequences encoding the units/parts shown in table 14:
TABLE-US-00014 Unit/Part Function 1: Native leader sequence for human MIP1α (LD78β) Signal peptide 2: Full-length human MIP1α (LD78β) sequence Targeting unit 3: Human hinge-region 1 from IgG3 Dimerization unit 4: Human hinge region 4 from IgG3 5: Glycine-Serine linker 6: Human CH3 domain from IgG3 7: Glycine-Leucine linker Unit linker 8: Patient-present shared antigen sequences: Antigenic unit VB4100, VB4101, VB4102 9: Patient-specific antigen sequences (neoepitopes) VB4097 10: Patient-present shared antigen sequences and patient-specific antigen sequences (neoepitopes): VB4105
DNA Vaccine VB4097 Comprising 10 CT26 Neoepitopes
[0354] This construct was chosen as a model of an individualized DNA vaccine comprising patient-specific antigen sequences, i.e., neoepitopes.
[0355] Previously described exome sequencing and RNA sequencing of the mouse colon cancer cell line CT26 revealed hundreds to thousands of tumor-specific non-synonymous mutations. In silico methods were used to identify potential immunogenic sequences, i.e., neoepitopes, and 10 of them (table 15) were chosen for inclusion into the antigenic unit of VB4097. Each of the identified 10 neoepitopes is a peptide consisting of 27 amino acids. All but the terminal neoepitope were arranged in subunits, each subunit consisting of one neoepitope and one flexible glycine-serine linker (GGGGSGGGGS).
[0356] VB4097 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 20.

DNA Vaccines VB4100, VB4101 and VB4102 Comprising NY-ESO-1 Sequences or Parts Thereof
[0357] These constructs were chosen as models of individualized DNA vaccines comprising patient-present shared antigen sequences.
[0358] Human New York esophageal squamous cell carcinoma 1 (NY-ESO-1) has been shown to be a highly immunogenic cancer testis antigen aberrantly expressed in several cancer types. NY-ESO-1 is not endogenously expressed in the CT26 cancer cell line, but using in silico methods, several immunogenic sequences were predicted to bind mouse MHC class I and II in BALB/c mice. The above-mentioned constructs were chosen as a model of an individualized DNA vaccine comprising patient-present shared antigen sequences.
[0359] Three NY-ESO-1 constructs were thus designed: [0360] VB4100 having an antigenic unit that comprises NY-ESO-1 in full length. VB4100 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 21. [0361] VB4101 having an antigenic unit that comprises amino acids 81-88 of the NY-ESO-1 sequence which is predicted to be an MHC class I antigen. VB4101 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 22. [0362] VB4102 having an antigenic unit that comprises amino acids 81-126 of the NY-ESO-1 sequence which contains several antigens that are predicted to be MHC class and class II antigens. VB4102 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 23.
[0363] The various NY-ESO-1 sequences comprised in the constructs are shown in table 16.

DNA Vaccine VB4105 Comprising 10 CT26 Neoepitopes and the Full-Length Sequence of NY-ESO-1 Sequence
[0364] This construct was chosen as a model of an individualized DNA vaccine comprising patient-present shared antigen sequences and patient-specific antigen sequences (neoepitopes). It comprises an antigenic unit comprising the full-length sequence of NY-ESO-1 and the 10 CT26 neoepitopes shown in table 1, each of them separated from the following neoepitope or the NY-ESO-1 sequence by a flexible glycine-serine linker (GGGGSGGGGS). VB4105 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 24.
Negative Control VB1026
[0365] This construct is identical to the aforementioned constructs, but comprises neither a unit linker, nor an antigenic unit. It serves as a negative control. VB1026 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 25.
Construction of Expression Vectors Comprising the Constructs and Confirmation of Expression and Secretion of Intact Dimeric Proteins Encoded by the Constructs
[0366] The sequences of the antigenic units of all aforementioned constructs were ordered from Genscript (New Jersey, USA) and cloned into the expression vector pUMVC4a; a master plasmid comprising a nucleotide sequence encoding the signal peptide, targeting unit and dimerization unit described in table 14 above.
[0367] HEK293 cells (ATCC) were transiently transfected with the above-mentioned constructs. Briefly, 2×10.sup.5cells/well were plated in 24-well tissue culture plates with 10% FBS growth medium and transfected with 1 .Math.g of respective DNA plasmid using Lipofectamine® 2000 reagent under the conditions suggested by the manufacturer (Invitrogen, Thermo Fischer Scientific). The transfected cells were then maintained for up to 5 days at 37° C. with 5% CO.sub.2. Later the cell supernatants were harvested for characterization of the expression of the proteins encoded by the constructs by sandwich ELISA of the supernatant using antibodies specific for anti hIgG (CH3 domain), hMIP-1α and the respective antigenic units.
Assessment of Immunogenicity of the Constructs
[0368] Immunogenicity of the constructs was determined by way of measuring the T cell immune response elicited in vivo in mice vaccinated with the constructs.
[0369] Female, 6-week-old BALB/c mice were obtained from Janvier Labs (France). All animals were housed in the animal facility at the Radium Hospital (Oslo, Norway). All animal protocols were approved by the Norwegian Food Safety Authority (Oslo, Norway). 5 mice/group were used for the testing of the constructs comprising an antigenic unit, whereas 3 mice/group were used for the negative control.
[0370] 20 .Math.g of the construct was administered intramuscularly twice, i.e., on day 0 and on day 21, followed by electroporation. Spleens were collected on day 28.
[0371] Spleens were mashed in cell strainer to obtain a single cell suspension. For each construct tested, a portion of the single cell suspension was used to purify CD4+ and CD8+ T cells using Dynabeads® depletion. Total splenocytes, CD4 depleted splenocytes and CD8 depleted splenocytes were then tested for production of INF-γ in ELISpot assays. The 10 neoepitopes shown in table 15 were used to re-stimulate the splenocytes harvested from mice vaccinated with constructs VB4097 and VB4105, while the NY-ESO-1 peptides shown in table 17 below were used to re-stimulate the splenocytes harvested from mice vaccinated with the construct indicated in said table.

Comparison of Immunogenicity of Constructs VB4097, VB4100 and VB4105
[0372] Constructs VB4097 (10 neoepitopes), VB4100 (NY-ESO-1 full length), and VB4105 (10 neoepitopes and NY-ESO-1 full length) were compared for their ability to elicit T cell immune response against the peptides in tables 15 (VB4097 and VB4105) and 17 (VB4100 and VB4105).
[0373] As shown in
[0374] VB4097 and VB4105, both comprising the same 10 CT26 neoepitopes, induce a similar a total T cell response (INF-γ response) against the 10 neoepitopes (
[0375] Also, VB4100 and VB4105, both comprising the full-length sequence of NY-ESO-1 induce a similar a total T cell response (INF-γ response) against the peptides used for re-stimulation as shown in table 17 (
[0376] For VB4105, the addition of the NY-ESO-1 full length sequence to the antigenic unit of VB4097 comprising the 10 neoepitopes did elicit a higher total T cell response compared to that elicited by vaccination with VB4097, due to the added immunogenicity against NY-ESO-1.
[0377] These results indicate that a vaccine according to the invention comprising a patient-present shared antigen is able to elicit an immune response which is similar to that of a vaccine comprising patient-specific antigens (neoepitopes). Moreover, these results indicate that there is a benefit in including both a patient-present shared antigen and patients-specific antigens (neoepitopes) into the antigenic unit.
Comparison of Immunogenicity of Constructs VB4100, VB4101 and VB4102
[0378] Using in silico methods, the epitope consisting of amino acids 81-88 of NY-ESO-1 was predicted to strongly bind to MHC class I to active CD8+ T cells, whereas the peptide consisting of amino acids 81 to 126 of NY-ESO-1 was predicted to contain several MHC class I and class II antigens. Therefore, constructs VB4100 (NY-ESO-1 full length), VB4101 (NY-ESO-1 amino acids 81-88) and VB4102 (NY-ESO-1 amino acids 81-126) were constructed and compared for their ability to elicit T cells immune response.
[0379] First, the three constructs were compared for their ability to elicit CD8+ T cell immune response against the predicted amino acid 81-88 region. The CD8+ T cells isolated from splenocytes of mice vaccinated with the constructs were re-stimulated with the amino acid 81-88 minimal epitope shown in table 16. As shown in
[0380] Next, VB4102 was compared to VB4100 to assess whether the several predicted MHC class I and class II antigens in the amino acid sequence 81-126 of NY-ESO-1 elicit a similar response as the full-length NY-ESO-1 sequence. The CD4+ T cells and CD8+ T cells isolated from splenocytes of mice vaccinated with the constructs were re-stimulated with the peptides shown in table 17. As shown in
[0381] These results suggest that by using in silico methods, short(er) sequences/epitopes of patient-present shared antigens can be identified that are predicted to elicit strong immune responses. By including such sequences/epitopes into the antigenic unit of the vaccine of the invention instead of longer sequences or the full-length sequence of a patient-present shared antigen, there is space left in the antigenic unit for including sequences of other patient-present shared antigens and/or patient-specific antigens/neoepitopes. This will enhance the chance that the patient receiving such an individual anticancer vaccine will show a strong immune response to the vaccine.
Example 8: Immunogenicity of DNA Vaccines According to the Invention Design of DNA Vaccines Comprising Shared Antigen Sequences and/or Neoepitopes
[0382] Six DNA vaccines (constructs) were designed comprising nucleotide sequences encoding the units/parts shown in table 18:

DNA Vaccine VB4118 Comprising 10 B16 Neoepitopes
[0383] This construct was chosen as a model of an individualized DNA vaccine comprising patient-specific antigen sequences, i.e. neoepitopes.
[0384] Previously described exome sequencing and RNA sequencing of the mouse melanoma cell line B16.F10 revealed hundreds to thousands of tumor-specific non-synonymous mutations. In silico methods were used to identify potential immunogenic sequences, i.e. neoepitopes, and 10 of them (table 19) were chosen for inclusion into the antigenic unit of VB4118. Each of the identified 10 neoepitopes is a peptide consisting of 27 amino acids. All but the terminal neoepitope were arranged in subunits, each subunit consisting of one neoepitope and one flexible glycine-serine linker (GGGGSGGGGS).
[0385] VB4118 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 26.

DNA Vaccines VB4119 Comprising a TRP-2 Sequence and VB4127 Comprising Frameshift Antigens
[0386] These constructs were chosen as models of individualized DNA vaccine comprising patient-present shared antigen sequences.
[0387] Tyrosinase related protein 2 (TRP-2) is a melanocyte lineage normal differentiation protein. This shared antigen (differentiation antigen) is known to induce tumor rejection of B16 melanoma cells in C57BL/6 mice in vivo. In the literature, the 9 amino acid long MHC class I epitope shown in table 20 (amino acids 180-188 of TRP-2) has been identified as the immunogenic sequence responsible for the anti-tumor effect of TRP-2.
[0388] VB4119 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 27

[0389] Frameshift mutations are DNA mutations that arise when indels (insertions or deletions) of nucleotides lead to a shift in the DNA reading frame. Consequently, the entire DNA sequence following the indel will be read incorrectly and the resulting protein will be altered. Frameshift mutations arising in tumor cells generate novel peptide sequences that could be highly immunogenic, and, moreover, identical frameshift antigens could arise across different patients, and thus represent promising targets for shared antigen cancer vaccines (see for instance Ballhausen et al., Nat. Commun. 11, 2020, 1-13). The three frameshift antigens shown in table 21 were identified as immunogenic by in silico methods and are encoded in the VB4127 construct. In the antigenic unit, they are separated from each other by a flexible glycine-serine linker (GGGGSGGGGS).

DNA Vaccines Comprising 10 B16 Neoepitopes and the TRP-2 Epitope (VB4121) or 10 B16 Neoepitopes and the 3 Frameshift Antigens (VB4128) or 10 B16 Neoepitopes, the TRP-2 Epitope and the 3 Frameshift Antigens (VB4130)
[0391] These constructs were chosen as models of individualized DNA vaccines comprising patient-present shared antigen sequences and patient-specific antigen sequences (neoepitopes). Each construct comprises an antigenic unit comprising the 10 B16 neoepitopes shown in table 19, each of them separated from the following neoepitope or the shared antigen sequence by a flexible glycine-serine linker (GGGGSGGGGS).The same linker was used to separate the shared antigens sequences in constructs comprising several of such sequences. VB4121 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 29; VB4128 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 30 and VB4130 consists of a DNA sequence encoding the polypeptide with amino acid sequence of SEQ ID NO: 31.
[0392] The construct VB1026, described in Example 7, was used as a negative control.
Construction of Expression Vectors Comprising the Constructs and Confirmation of Expression and Secretion of Intact Dimeric Proteins Encoded by the Constructs
[0393] The expression vectors comprising the aforementioned constructs were constructed as described in Example 7. Expression and secretion of intact dimeric proteins encoded by the constructs was confirmed as described in Example 7.
Assessment of Immunogenicity of the Constructs
[0394] Immunogenicity of the constructs was determined by way of measuring the T cell immune response elicited in vivo in mice vaccinated with the constructs.
[0395] Female, 6-week-old C57BL/6 mice were obtained from Janvier Labs (France). All animals were housed in the animal facility at the Radium Hospital (Oslo, Norway). All animal protocols were approved by the Norwegian Food Safety Authority (Oslo, Norway). 5 mice/group were used for the testing of the constructs comprising an antigenic unit, whereas 3 mice/group were used for the negative control.
[0396] 20 .Math.g of the construct was administered intramuscularly on day 0 followed by electroporation. The spleens from the vaccinated mice were collected on day 14. The collected spleens were processed and ELISpot assays were carried out as described in Example 7.
[0397] The 10 neoepitopes shown in table 19 were used to re-stimulate the splenocytes harvested from mice vaccinated with the constructs VB4118, VB4121, VB4128, and VB4130. The TRP-2 peptide in table 20 was used to re-stimulate the splenocytes harvested from mice vaccinated with the constructs VB4119, VB4121, and VB4130. The frameshift peptides shown in table 22 below were used to re-stimulate the splenocytes harvested from mice vaccinated with the constructs VB4127, VB4128, and VB4130.

Comparison of Immunogenicity of Constructs VB4118, VB4119, VB4121, VB4127, VB4128, and VB4130
[0398] Constructs VB4118 (10 neoepitopes), VB4119 (TRP-2), VB4121 (10 neoepitopes and TRP-2), VB4127 (3 frameshift antigens), VB4128 (10 neoantigens and 3 frameshift antigens), and VB4130 (10 neoepitopes, 3 frameshift antigens and TRP-2) were compared for their ability to elicit T cell immune response against the peptides in tables 19, 20, and 22, as applicable.
[0399] As shown in
[0400] Both the model construct of a vaccine comprising only patient-specific antigens (VB4118) and the model constructs of vaccines comprising only patient-present shared antigen(s) (VB4119 and VB4127) elicit an immune response in the vaccinated mice.
[0401] VB4118, VB4121, VB4128, and VB4130, all comprising the same 10 B16 neoepitopes, induce a similar total T cell response (INF-γ response) against the 10 neoepitopes (
[0402] Further,
[0403] Also the results of this study indicate that a vaccine according to the invention comprising a patient-present shared antigen can elicit an immune response which is similar to that of a vaccine comprising patient-specific antigens (neoepitopes). Moreover, these results indicate that there is the benefit of an increased broader and total T cell response by including different types of shared antigens and patients-specific antigens (neoepitopes) into the antigenic unit.
