Description

Polypeptide vaccine composition of kinase inhibitor aiming at targeted drugs PI3K, AKT and mTOR pathways and design method thereof
The present case is application number: 201910086371.9, title of the invention: a polypeptide vaccine aiming at a tumor targeted drug resistance site and a patent of a design method thereof.
Technical Field
The invention relates to the field of tumor vaccines, in particular to a polypeptide vaccine aiming at tumor targeted drug resistant sites and a design method thereof.
Background
In recent years, the progress of tumor-targeted therapy has entered a completely new era with the development of molecular biological techniques and further understanding of the pathogenesis from the cellular and molecular level. These fields are rapidly progressing and to date, many targeted drugs have played an extremely important and even fantastic role in the clinic. Molecular targeted therapy has become another important means for tumor therapy such as surgery, radiotherapy, chemotherapy and the like, and plays an increasingly important role in tumor therapy. The advantages over traditional therapies and chemotherapy are evident due to the high efficiency and low toxicity of targeted therapies. Targeted therapies have developed rapidly, and some have entered standard treatment protocols and specifications recognized by the international oncology community according to evidence-based medical principles. More and promising drugs are also under development in Haimaicha and early clinical trials. The targeted medicine has become a great tool for treating tumors. However, with longer and longer treatment times, resistance occurs in most patients. As for the specific mechanism of drug resistance, there are currently 3 main types. First, resistance is generated by gene mutation. About 40% of the genes in the patients who are positive in the gene test result in new genes from the original genes, which results in insensitivity to the original drugs and thus drug resistance. Secondly, subtle cancer cells often make a 'trestle dark store' and go around to bend another way. This condition accounts for about 20% of patients with drug resistance. In addition to the above two resistance routes, the resistance mechanism of about 30% of patients remains unclear. The "change" of target (resistance) is inevitable and almost all targeted drug therapies exhibit resistance, the root cause of which is due to heterogeneity and dynamic changes of cancer cells. At present, a targeting drug acts on a certain protein and a certain molecule of cancer cells, so that only one pathway of tumor growth can be inhibited. When one pathway is inhibited, tumor cells can self-seek a new 'birth pathway', other pathways are selected to synthesize substances required for self growth, and the molecular targeted drug loses the effect over time, so that drug resistance is generated, for example, after EGFR mutation patients take the targeted drug, 50% -60% of patients have drug resistance because of genetic mutation again, most of the mutations are T790M mutations, and at the moment, the patients can use third generation targeted drugs such as Ostinib. Most patients will have secondary drug resistance 8-14 months after receiving EGFR-TKI treatment, and how to solve the drug resistance problem of targeted drug treatment becomes a hotspot of research.
In recent years, the search for tumor polypeptide vaccines has been favored due to the discovery of tumor-associated antigens and tumor-specific antigens, as well as the intensive research and understanding of tumor-induced immune responses and tumor evasion immune surveillance mechanisms. The new antigen is abnormal protein expressed on the surface of tumor cells caused by gene mutation, and is different from the conventional antigen target in that the new antigen is only expressed on the surface of the tumor cells and not expressed on the surface of normal cells, and can be recognized by the immune system and activate the immune system. In 2017, month 7 and day 13, the same day as Nature journal issued two successful cases of neoantigen-based personalized tumor vaccine for treating malignant melanoma. Professor Carmen Loquai in Germany and
Figure GDA0003657876590000011
professor Tureci used the RNA corresponding to neoantigen as a vaccine to treat 13 patients in total. On the same day, the case of treating malignant melanoma was also successfully reported by the team led by the professor of cathine j.wu of harvard university, using the antigenic peptide corresponding to neoantigen as a vaccine. The general design process of drug-resistant site polypeptide vaccine is to find out the mutation sites leading to drug resistance of the target drug, analyze the neoantigen generated by these mutations, and prepare the polypeptide vaccine capable of being specifically recognized by the histocompatibility complex (MHC) of the patient, where the polypeptide preparation can be obtained by chemical synthesis, by transcription and translation using nucleic acid molecules (such as DNA and RNA), or by expression using bacteria or virus as a vector. The polypeptide vaccine is injected into a patient body to activate specific T cell response and immune storm, so that the patient's own immune system can effectively identify and kill the tumor cells with drug-resistant mutation. The polypeptide vaccine and the targeting drug are combined for use, on one hand, the targeting drug can kill tumor cells carrying drug targets, on the other hand, the immune system of the organism activated by the polypeptide vaccine can effectively identify and recognize the drug-resistant tumor cells just before the drug-resistant tumor cells appearThe active immune system can maintain the killing effect on tumor cells in vivo for a long time, ensure the continuous inhibition on the drug resistance phenomenon and overcome the drug resistance of the targeted drug generated by drug resistance mutation to a certain extent. The market needs a set of screening and designing methods of the polypeptide vaccine aiming at the tumor targeted drug resistance site, can effectively reduce the occurrence probability of tumor resistance, has broad spectrum, shortens the time from analysis to treatment of the individualized polypeptide vaccine, and reduces the medical cost; the present invention solves such problems.

Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
The design method of the polypeptide vaccine aiming at the tumor targeted drug resistance site comprises the following steps:
1. collecting the drug resistance mutation data of the targeted drugs: the human cancer-associated somatic mutation catalog Cosmic (database official website https:// cancer. sanger. ac. uk/Cosmic) collates and notes reports of acquired resistance and primary resistance in clinical studies, including information of genes, mutations, drugs, cancer species and references. We downloaded all targeted therapeutic drug resistance mutation sites that were approved by FDA or CFDA or in clinical trial III/IV, and especially the less sample-size supported mutations for all candidate targeted drugs and resistance mutations, further looked up literature to determine their reliability, and determined truly fully reliable targeted drug resistance sites for downstream analysis, e.g., cosmic included a report confirming that the EGFR-T790M mutation is an austenitinib resistance site, but found through the look-up literature that T790M is not an austenitinib resistance site.
2. Intercepting a drug-resistant mutant polypeptide sequence and predicting MHC molecule affinity and immunogenicity:
2.1, intercepting a polypeptide sequence covering 16 amino acids at the upstream and downstream of a mutation site for point mutation, intercepting a polypeptide sequence which extends forwards for 16 amino acids and extends backwards to a stop codon for frameshift mutation to serve as a mutant polypeptide of the drug-resistant mutation site, and intercepting a wild-type polypeptide sequence corresponding to a corresponding position.
2.2, counting high-frequency HLA types and frequencies: the source of the high-frequency HLA mainly comprises two parts, namely statistics (IMGT/HLA and Chinese marrow bank) from public databases, combines information reported by recent literature, and summarizes common HLA allelic gene typing of Chinese population; secondly, a group of HLA types with higher occurrence frequency is counted from the database of clinical patients, and the specific database is shown in Table 2. The two groups of HLA were pooled and de-duplicated before being used as candidate HLA typing for prediction. It should be noted that the choice of the database is not limited, and this is only a preferred embodiment, and may also be a combination statistic of several other databases.
2.3, the binding affinities of the polypeptides corresponding to the mutation sites and the HLA molecules obtained in the step 2.2 are analyzed by using three software of netMHCpan, netMHC and Pickpocksocket, the three software are synthesized to divide the affinities into three classes (strong affinity-SB, weak affinity-WB and no affinity), and the affinity changes are determined by comparing with the relative wild-type polypeptides (no affinity is changed into strong affinity to define the class A change, no affinity is changed into weak affinity to define the class B change, weak affinity is changed into strong affinity to define the class C change, other no change is defined as the class D change, and the internal ordering considers that the class A is superior to the class C and is superior to the class D), in addition, an immunogenicity prediction tool provided by IEDB is used for predicting the immunogenicity of the polypeptide, epitopes with strong affinity, large affinity change and strong immunogenicity of mutant polypeptides are reserved, and 137 drug-resistant mutations corresponding to 31 targeted drugs are obtained through co-screening.
3. Target drug and drug-resistant site correlation and drugClustering objects: 3.1 scoring the affinity of the drug-resistant site: comprehensively considering the number of epitopes with affinity of the site and the change size of the affinity of each epitope (a, giving different weights to A, B, C, D four types of different affinity changes, b, giving weights according to the HLA frequency size corresponding to each epitope, and c, accumulating and summing the epitopes of the site).

AC: the size of the affinity change, A, B, C, D four different types of affinity changes are given different weights; fhla: a corresponding HLA frequency; n: the number of each epitope of the locus;
3.2 using cytoscape to make a network map (as shown in figure 1) of all the targeted drugs and the drug-resistant sites, wherein the size of the drug-resistant sites represents the affinity scores of the drug-resistant sites, and the mutual relation between the targeted drugs and the drug-resistant sites is comprehensively analyzed, and the targeted drugs are clustered by combining the action mechanism of the targeted drugs, so that the targeted drugs are divided into 7 types as shown in figure 1. The drug-resistant Hedgehog signaling pathway antagonist virginia for SMO mutation generation, the drug-resistant ibrutinib for BTK mutation generation, the drug-resistant epirubitinib for AR resistance mutation generation, the drug-resistant epirubicin for BRAF resistance mutation generation, the tyrosine kinase inhibitor for ALK, MET fusion gene, the tyrosine kinase inhibitor for EGFR pathway generation, and the kinase inhibitor for PI3K, AKT, mTOR pathway everolimus generation. Because the clustering of the targeted drugs comprehensively considers the interaction between the drug action mechanism and the drug-resistant sites, the targeted drugs with similar action mechanism and cross drug-resistant sites are clustered into a class, thereby maximally covering the drug-resistant sites with immunogenicity of the targeted drugs, and remarkably reducing the phenomenon of 'off-target' caused by the difference of HLA molecules of patients, so that the polypeptide vaccine can kill tumor cells with similar drug-resistant mutations in the maximum range, and the effectiveness of the polypeptide vaccine is remarkably improved compared with that of a single-drug vaccine.
4. Designing a polypeptide vaccine sequence: as an example, the corresponding vaccine polypeptide sequence can be designed manually, or the polypeptide vaccine sequence can be designed by inputting the vaccine design program iNeo-VaDes (V1.2) developed by us. As a polypeptide vaccine therapy aiming at targeted drug resistance, in the design process of vaccine polypeptide, the invention considers the distribution of antigen epitope, covers the epitope containing mutation sites as much as possible, and also considers the factors influencing the amino acid synthesis efficiency such as the length and the hydrophobic rate of the polypeptide and the factors influencing the safety of the polypeptide such as the toxicity and the homology of the polypeptide. The vaccine polypeptide combination of the present invention consists of polypeptide sequences comprising the following 137 mutations, as shown in table 1 below. 5. Preparing a vaccine: the polypeptide vaccine can be prepared by directly using chemical synthesis, can be obtained by transcription and translation by using nucleic acid molecules (such as DNA and RNA), or can be obtained by expression by using bacteria or virus as a vector. In this case we used chemical synthesis to obtain the polypeptide vaccine.

the invention provides a polypeptide vaccine of 31 targeted drugs, which basically covers common tumor targeted drugs and is used for experimental verification of the immunogenicity of each polypeptide by the following experiments:
experiment 1, determination of immunogenicity of polypeptides; purpose of the experiment: through ELISpot experiments, the polypeptides corresponding to 7 products in the invention are verified to cause immune response in humanized mice. The experimental method comprises the following steps: experimental polypeptides: 7 product polypeptides are synthesized by Nanjing Jinslei Biotech Co., LtdThe purity is more than 90%, and the content of endotoxin is less than 0.5 EU/mg. To detect the immune response of the polypeptide, an IFN- γ Enzyme Linked Immunosorbent (ELISPOT) assay is performed. The detailed experimental procedure is as follows: 24 humanized mice B-NSG (CD34+) were selected at 8 weeks of age and randomized into 8 groups of 3 mice each. After one week of adaptation, the samples were divided into polypeptide group 1 (corresponding to product 1), polypeptide group 2 (corresponding to product 2), polypeptide group 3 (corresponding to product 3) … … polypeptide group 7 (corresponding to product 7), and 7 groups and negative control group No. 8 were counted. CpG was used as adjuvant (0.2. mu.g/mouse), 50. mu.g of polypeptide was added to Freund's incomplete adjuvant (FIA, Sigma-Aldrich) 1:1, mixing and emulsifying for 30 minutes, mixing PBS with Freund's incomplete adjuvant 1:1 mixed emulsification for 30 minutes as a negative control, four times of subcutaneous immunization is carried out on the right chest of the back and the neck, the total dose is 0.5 mL/mouse, once every 1 week for three weeks, and 10 days after the third immunization, the spleen of the mouse is taken to prepare mouse lymphocyte suspension for ELISPOT detection. In the ELISPOT detection result, the polypeptide with positive IFN-gamma result is determined as the positive candidate polypeptide. Experiment Single peptide ELISPOT test was performed separately according to groups, i.e., mice were diluted to 1-2 x 10 lymphocyte concentration6Laying on 24-well plate, dividing into control group (DMSO with the same concentration as polypeptide) and corresponding single polypeptide group, numbering PHA positive control group (PHA lymphocyte is from negative control group), repeating each treatment 3 times (3 multiple wells), adding corresponding polypeptide (10 μ g/mL), pre-incubating for 72h, centrifuging, and adjusting cell concentration to 2 x 106The resulting spots were then visualized using IFN-. gamma.Elispot plates in accordance with the protocol of the IFN-. gamma.ELISPOT kit, and read using a CTL-ImmunoSpotoS 5 series enzyme-linked spot analyzer. The positive result of IFN-gamma indicates that antigen specific T cells are generated, the polypeptide can be regarded as capable of causing the immune reaction of the organism, and the number of spots reflects the intensity of the immunity.
The experimental results are as follows: in order to further clarify the immune response of each individual polypeptide, ELISPOT experiments of the corresponding single peptide in each polypeptide group were performed, the number of spots generated by each polypeptide is shown in FIGS. 2A-D, each of which can cause immune response, but the spot difference generated by each polypeptide is relatively large, and varies from 10 spots to 200 spots, while the control group generates substantially no spots. And (4) analyzing results: the polypeptides corresponding to 7 products in the invention can cause immune response in humanized mice.
