    Example 1: Transcriptome Analysis [mRNA Expression]

    [0342] Transcriptome analysis (sequencing) was performed in all patients using PANTHER chip analysis (44K chip) from Agilent Technologies. The 44K chip used contains 44,000 gene probes, so that the activity of >34,000 gene expression markers could be analyzed with this chip per patient in each case. In each case, 1,000 genes with increased relevance were determined 10-fold.

    [0343] The evaluation is based on published gene signatures known to the expert.

    Example 2: EXOM Sequencing

    [0344] Exome sequencing is performed from the standard frozen specimen of the patients from whom the tumor DNA is extracted. Next-generation sequencing of the exome is performed from the tumor sample with coverage of more than 95% of the entire human coding exon region. For this purpose, among others, >290,000 relevant sections of DNA are selectively amplified and sequenced by semiconductor sequencing technology.

    [0345] The aim of the analysis is to define possible mutations for the design of an individual tumor antigen peptide immunization. To exclude non-tumor associated variants (SNPs, Single Nucleotide Polymorphism) of the germline, DNA is simultaneously isolated from nucleated blood cells of the patients and comparatively sequenced using the same methodology. The differentiation of potential neoantigen candidates was performed in the following six steps: [0346] 1) Selection of tumor/somatic mutations is reduced by exclusion of non-tumor specific polymorphisms. [0347] 2) The predefined selection of somatic mutations is further restricted to quality parameters, read coverage and influence on the protein sequence. More complex mutations than single amino acid substitutions SNPs, and mutations in non-protein coding regions are excluded. Silent mutations are also excluded. [0348] 3) The mutations defined in this way are expanded to flanking 20s oligopeptides using the known protein sequences (RefGene database). From these, 12×9 oligopeptides each were formed sequentially and the affinity to the pre-known, patient-specific hypervariable HLA-I paratopes was determined (program NetMHC-4.0). Nonapeptides with high affinity to the paratopes, which show a further increase in affinity compared to the wild type sequence due to the mutation (SNP), were selected. [0349] 4) Candidates carrying this mutation as a germline mutation in an exome pool at the same position are excluded (NIH-NHLBI 6500 exome database version-2 program ANNOVAR-Tool2.) [0350] 5) Based on the results of the expression analysis (see findings under embodiment example 1), peptides with a low expression relevance in the tumor can be excluded. [0351] 6) Finally, we will examine in detail whether further polymorphisms may be present in the vicinity of the single base exchange and thus represent further, patient-specific deviations from the hg19 defined genome sequence.
    The following is an example of the evaluation of the results of the described mutation analysis and filtration steps for one patient: [0352] 1) Comparison of tumor DNA versus normal DNA [0353] a. “Exome_single_sample_Somatic” using the IonReporter yields: [0354] 37494 variants in normal DNA, and [0355] 37299 variants in tumor DNA. [0356] The paired analysis “AmpliSeq Exome tumor-normal pair” detects and annotates rare somatic variants (SNPs, InDels, CNVs) using statistical analysis in the Ion AmpliSeq Exome Panel (Ion Reporter Software 4.6. Workflow Version: 1.0). This results in: 1477 mutations in the tumor with concurrent wild type categorization in the normal DNA. [0357] These 1477 variants are the starting point for further restrictions. [0358] 2) Restriction of variants to protein-coding SNP (single nucleotide polymorphisms) with amino acid substitution. [0359] Restriction to SNPs [0360] At least 50× sequenced in tumor and min. 20× sequenced in blood [0361] Must not have occurred in the blood in any single run [0362] Must be positioned in an exon [0363] Must result in amino acid exchange (missense mutation) [0364] 3) From these variants, 20s peptides are defined and fed to the HLA paratope affinity analysis NetMHC. [0365] ˜25*12 nonapeptide pairs (each mutant and wild type) are submitted to affinity analysis for analysis in 9 HLA loci each. Out of these 5814 affinities (2907 pairs) are analyzed. In 40 pairs, an affinity at least 2-fold higher in the mutated peptide than in the wild-type peptide is detected.

[0368] Database filters used: hg19_esp6500siv2_all [0369] 5) Selection from remaining 25 variants with significant mRNA expression (>3 fold versus normal tissue) in alignment with transcriptome

    Example 3: Patients with mMC (Metastatic Breast Carcinoma), Type_HER2-Neu

    [0370] 1) Clinical history of the patients

    [0371] Patient, Female

    [0372] Initial clinical findings: invasive ductal bifocal breast carcinoma (breast CA), right, tumor 2 cm to 5 cm in greatest extent (pT2), pN1sn pN1 (3/5) G2, NO, ER-, PR-, HER-2 new: 3+, Ki-67: 55%.

    [0373] Treatment Procedure: [0374] 2 weeks later: Neoadjuvant chemotherapy (TCH w3) 6 cycles, trastuzumab; [0375] 6 months later: Irradiation of the right breast+lymphatic drainage area (LAG).

    [0376] Tumor completely destroyed by radiotherapy or chemotherapy (CR=complete remission) of tumor, findings: patient discharged from hospital as cured.

    [0377] Recurrence: Local recurrence with additional liver metastases (4 foci) occurs 24 months after initial diagnosis; findings: ER−, PR+(60%), HER-2 new: 3+, Ki-67: 80%.

    [0378] This recurrent mammary/breast CA occurred with liver metastases and also had significantly greater aggressiveness (Ki-67: 80% versus 55% (initial finding)).

    [0379] Prognosis of the clinicians: The patient was discharged from the hospital with a prognosis of OS (overall survival) expected/average of 6 months.

    [0380] The well-known fact that in breast CA, second primary malignancy (SPM) flared up again is associated with worse prognosis and with worse OS (see “Breast cancer survivors face excess risk for second primary cancer in SEER analysis,” Wei J L & al,

    [0381] Int J Clin Oncol, Mar. 19, 2019), likely triggered by prior chemotherapy,

    [0382] Treatment Procedure: [0383] 2 months after diagnosis: surgical removal of the mammary gland and adjacent tissues of the right breast (mastectomy) because of a local recurrence that had occurred there. [0384] 4 months after diagnosis: Appearance of bone metastases (osseous metastases (spine)) and bronchial carcinoma (suspicious LK pulmonary hilus); [0385] 9 months after diagnosis: surgical removal of the mammary gland and adjacent tissues of the left breast.

    [0386] Tumor progression despite trastuzumab or T-DM1 continuous therapy [0387] 2) Individualized Immune Information Therapy: Analytics

    [0388] After therapy/treatment procedures under point 1 had been carried out without success, the immunological therapy approach of informing the patient's own immune system by means of application of tumor-associated and tumor-specific HLA antigen peptides in the form of synthesized peptides was used as part of a curative trial.

    [0389] The focus was on the cellular immune defense, i.e. the activation of the endogenous cytotoxic CD8+ T cells, which as naive T cells are able to recognize virtually all conceivable pathogenic as well as malignant amino acid sequences (the so-called “targets”) by means of a highly differentiated receptor system and thus develop into effector cells. These effector T cells can destroy the tumor cells recognized via the HLA-present antigens by secreting granzyme and perforin.

    [0390] For this purpose, data were collected from biopsied tumor tissue of the patients via “next generation sequencing” (NGS) and “liquid chromatography-coupled tandem mass spectrometry” (LC-MS/MS) using the following three steps [0391] the mRNA expression of all coding gene regions (transcriptome—step (a)), [0392] the tumor-specific somatic miss-sense mutations as well as via (exome sequencing—step (b)) [0393] the HLA-restricted ligands of the HLA classes I+II presented by the tumor cells (HLA ligandome—step (c))
    to step (a): The mRNA expression data (approximately 40,000) were compared with the expression levels of healthy tissue and filtered with respect to [0394] significant (>3-fold) deviation of the expression values, and further [0395] with regard to the significance of the genes concerned for tumor development [0396] according to the criterion that these genes may not be expressed or only slightly expressed in other tissue types [0397] furthermore, with regard to the group of cancer-testis antigens, which are generally not expressed in healthy mammary tissues of adults, notable expressions in the tumor were recorded, since these may have the quality of a tumor-specific antigen

    [0398] This resulted in a separate data set of possible HLA tumor antigen peptides (number 86), which were weighted with respect to their expression abnormalities/deviations from normal and their known importance for tumor proliferation->factor 3 vs. normal; importance for tumor development: growth factors, angiogenesis factors, metastasis factors.

    to step (b): The somatic miss-sense mutations (single nucleotide variants (SNV) with an exchange of one amino acid as well as frame-shift mutations) (number: 57) were combined in another data set, since they are potentially significant (neo)-antigens in character and thus highly tumor-specific.
    to step (c): The HLA-restricted ligands (amino acid sequences of 9-10 AS (corresponding to MHC class I complexes) (number:1100) and sequences of 12-15 AS (corresponding to MHC class II complexes) (number:730) were screened using information from specialized databases for [0399] already appeared in healthy tissue (=negative) [0400] In protein match with promising sequences from transcriptome and exome, whether sequences of the identified tumor-associated HLA antigen peptides are associated with proliferation, invasiveness, angiogenesis, and/or an increase in cytokeratin production of mammary/breast carcinoma.

    [0401] In parallel to these described tumor tissue examinations, the genetic haplotype, the alleles of the HLA antigen peptides corresponding to the patient's MHC class I complexes were determined. The patient-individual result resulted in the following assignment:

    HLA-A*02:01, A*24:02, B*18:01, B*51:01, C*07:01, C*15:02; HLA-DRB1*09:01; DRB1*16:01, DQB1*03:03, DQB1*05:02.

    [0402] (With the support of HLA-A*02:01 in connection wirh B*18:01 this patient represents about 40% of the population living in Europe (Caucasian)). [0403] 3) individualized immune information therapy: target selection
    to step (a): From the data sets of the transcriptome, amino acid sequences of the respective proteins were first used to select amino acid sequences of the HLA tumor antigen peptides corresponding to the MHC complexes (nonamers) with the highest allelic affinities (specific activity towards T cell receptor [nM]). This selection criterion is used to algorithmically determine the probability with which the respective HLA tumor antigen peptide is presented in vivo on the corresponding MHC complexes (a first prerequisite for a possible cellular immune response).
    to step (b): From the data sets of the mutation tests, nonameric variants involving amino acid exchange were determined with respect to the highest affinities (specific activity towards T cell receptor [nM]) based on the alleles of the patient. Also, polymers of 17 amino acids (oligopeptides) were determined under the affinity criterion for this purpose. This selection criterion algorithmically determines the probability with which the respective tumor antigen peptide corresponding to the MHC complexes is presented in vivo on the corresponding MHC complexes (a second prerequisite for a possible cellular immune response).
    step (c): Based on the new data sets identified in step (a) and (b), with the addition of the HLA-restricted ligands (the data set of the ligandome), a selection of HLA tumor antigen peptides corresponding to MHC class I complexes and corresponding to MHC class II complexes was made, which were the most promising epitope candidates for eliciting a cellular immune response, both individually and especially in their combination. [0404] 4) Individualized Immune Information Therapy: Peptide Synthesis and Delivery Solution
    step (a): The peptide concepts selected for the custom application solution were synthesized as chemical peptides.
    step (b): the following 7 HLA-A tumor antigen peptides corresponding to MHC class I complexes and 2 HLA tumor antigen peptides corresponding to MHC class II complexes were mixed in a 33% DMSO/H.sub.2O application solution and divided into 24 vial units of 1 ml each.

    [0417] Beispiel 4: Patients with mIBC with lymphangosis carinomatosis (metastatic inflammatory breast cancer) [0418] 1) Clinical history of the patients

    [0419] Patient, female (46 years)

    [0420] The initial clinical findings: inflammatory breast carcinoma right with extensive lymphangiosis carcinomatose; Initial tumor stage pT4, pn3a (24/29)(Level 11:14/19, Level III: 10/10), MO, L1, VO, G2. HR+, PR+, Androgenr.+, HER2/neu−

    [0421] Recurrence: Postoperatively, a first recurrence already after 3 months: Progression of findings intramammary in the area of the right lower quadrant with significant increase in consistency of the breast tissue. Skin infiltration crossing the midline in the area of the thoracic wall as well as locoregional tumor infiltration of the axillary adipose tissue and the lateral thoracic wall along the pectoralis major muscle on the right.

    [0422] After 5 months locoregional tumor recurrence, with extension into the axilla.

    [0423] Chemotherapy from month 6 to month 11, discontinued after 5 cycles if tumor progression during chemotherapy. Locoregional tumor recurrence, 7×11 cm along ventrolateral thoracic wall. Skin and subcutaneous tissue extensively infiltrated and thickened.

    [0424] Hormone therapy with aromatase inhibitor and irradiation of the right breast, chest wall and supraclavicular/cervical right side.

    [0425] Prognosis of the clinicians: Overall survival for an expected 3-4 months. (Inflammatory breast carcinoma is a relatively rare, particularly aggressive form of breast carcinoma, which in this case 2 had already spread to the lymphatics (24 of 29 lymph nodes were already affected at initial diagnosis)).

    [0426] Treatment process according to the invention: After all therapies available in the standard and regular canon of oncological medicine had been carried out without success, the immunological therapy approach of informing the patient's own immune system by means of application of tumor-associated and tumor-specific antigens in the form of synthesized peptides was used in the context of a curative trial.

    [0427] The focus was on the cellular immune defense, i.e. the activation of the endogenous cytotoxic CD8+ T cells, which as naive T cells are able to recognize virtually all conceivable pathogenic as well as malignant amino acid sequences (hereinafter the “targets”) by means of a highly differentiated receptor system and thus develop into effector cells. These effector T cells can destroy the tumor cells recognized via the HLA-present antigens by secretion of granzyme and perforin.

    [0428] Activation of these immune cells occurs via HLA class I ligands, i.e. antigens presented as sequences of 8-10 amino acids restricted on class I HLA molecules.

    [0429] In months 14-84 after initiation of individualized immunoinformatics therapy, additional local recurrences (lymph nodes) occurred, each of which was surgically removed. However, distant metastasis was prevented. [0430] 2) Individualized Immune Information Therapy: Analytics

    [0431] To identify tumor-associated and tumor-specific antigen peptides, data were determined from biopsied tumor tissues of the patients using next generation sequencing (NGS) and liquid chromatography-coupled tandem mass spectrometry (LC-MS/MS) in the following three steps: [0432] the mRNA expression of all coding gene regions (transcriptome—step (a)), [0433] the tumor-specific somatic miss-sense mutations as well as via (exome sequencing—step (b)) [0434] the HLA-restricted ligands of the HLA classes I+II presented by the tumor cells (HLA ligandome—step (c))
    to step (a): The mRNA expression data (approximately 40,000) were compared with the expression levels of healthy tissue and filtered with respect to [0435] significant (>3-fold) deviation of the expression values, and further [0436] the significance of the genes concerned for tumor development [0437] the criterion that these genes may not be expressed or only slightly expressed in other tissue types [0438] furthermore, with regard to the group of cancer-testis antigens, which are generally not expressed in healthy mammary tissues of adults, notable expressions in the tumor were recorded, since these may have the quality of a tumor-specific antigen

    [0439] This resulted in a separate data set of possible HLA tumor antigen peptides (number 86), which were weighted with respect to their expression abnormalities/deviations from normal and their known importance in tumor proliferation.

    to step (b): The somatic miss-sense mutations (single nucleotid variants (SNV) with an exchange of one amino acid as well as frame-shift mutations) (number: 41) were combined in another data set, since they are potentially significant (neo)-antigens in character and thus highly tumor-specific.
    to step (c): The HLA-restricted ligands (amino acid sequences of 9-10 AS (corresponding to MHC class I complexes) (number:1321) and sequences of 12-15 AS (corresponding to MHC class II complexes) (number:863) were screened using information from specialized databases for [0440] already appeared in healthy tissue (=negative) [0441] protein match with promising sequences from transcriptome and exome, whether sequences of the identified tumor-associated HLA antigen peptides are associated with proliferation, invasiveness, angiogenesis, and/or an increase in cytokeratin production of mammary/breast carcinoma.

    [0442] In parallel to these described tumor tissue examinations, the genetic haplotype, the alleles of the HLA antigen peptides corresponding to the patient's MHC class I complexes were determined. The patient-individual result resulted in the following assignment:

    HLA-A*01:01, A*29:02, B*08:01, B*44:03, C*07:01, C*16:01; HLA-DRB1*03:01; DRB1*07:01, DRB3*01:01, DRB1*03:01, DRB4*01:01, DQB1*02:01, DPB1*01:01

    [0443] (With the support of HLA-A*01:01 in connection with B*08:01 this patient represents about 25% of the population living in Europe (Caucasian)). [0444] 3) Individualized Immune Information Therapy: Target Selection
    to step (a): From the data sets of the transcriptome, amino acid sequences of the respective proteins were first used to select amino acid sequences of the HLA tumor antigen peptides corresponding to the MHC complexes (nonamers) with the highest allelic affinities (specific activity towards T cell receptor [nM]).

    step (b): the following 9 HLA-A tumor antigen peptides corresponding to MHC class I complexes and 2 HLA tumor antigen peptides corresponding to MHC class II complexes were mixed in a 33% DMSO/H.sub.2O application solution and divided into 6 vial units of 1.5 ml each.

    [0456] The clinical efficacy of the applied immunotherapy in the illustrated embodiment 4 is shown in FIG. 5.

    [0457] The graph represents the development of the tumor markers CEA (bar 1) and CA15-3 (bar 2) as well as the liver value gamma-GT (bar 3) and the leukocyte count (bar 4) during a period of 8 months after application of the pharmaceutical composition according to embodiment 4. This was preceded by aggressive tumor progression—essentially based on inflammatory lymphangiosis carcinomatosis. The application was performed with a 1:1 mixture of Montanide ISA 51 VG with the peptide cocktail. The volume was 3 ml and was applied s.c. at the 4 different application loci (see pt 5). In this peptide composition, it is the initial application (followed by 4 further applications; see arrows in FIG. 5).
