Abstract
Description
Technical Field
[0001] (Cross - Reference to Related Applications) This application claims priority to U.S. Provisional Patent Application No. 62 / 402,695, filed on September 30, 2016, and U.S. Provisional Patent Application No. 62 / 468,124, filed on March 7, 2017, the entire contents of which are incorporated herein by reference.
[0002] Disclosed herein are compositions and methods for treating cancer, and in particular, immunogenic compositions that treat tumor growth and provide protection against tumor growth.
Background Art
[0003] Cancer is one of the leading causes of death worldwide and in the United States, ranking second among the most common causes of death and accounting for approximately one - quarter of all deaths. Cancer originates from a single cell that has changed from a normal cell to a tumor cell. Such changes are often a multi - step process that progresses from a pre - cancerous lesion to a malignant tumor. This progression involves many factors, including aging, genetic contributions, and exposure to external causative agents such as physical carcinogens (e.g., ultraviolet and ionizing radiation), chemical carcinogens (e.g., asbestos, components of tobacco smoke), and biological carcinogens (e.g., certain viruses, bacteria, and parasites).
[0004] The prevention, diagnosis, and treatment of cancer can take many different forms. Prevention can include screening for predisposing factors (e.g., specific gene variants), modifying habits (e.g., smoking, diet, and exercise levels), and vaccination against viruses (e.g., human papillomavirus, hepatitis B virus). Treatments can include chemotherapy, radiation therapy, and surgical removal of tumors or cancerous tissue. Despite the availability of numerous prevention and treatment methods, such methods often achieve only limited success in the effective prevention and / or treatment of common cancers.
[0005] Accordingly, there is a need for the identification and development of cancer prevention and / or treatment compositions and cancer prevention and / or treatment methods to facilitate the clinical management of protection against disease progression. Further, in subjects suffering from cancer, more effective treatments are sought to delay disease progression and / or reduce mortality.

Mode for Carrying Out the Invention
[0024] The present invention relates to an immunogenic composition comprising a synthetic consensus TERT antigen, alone or in combination with at least one additional cancer antigen or an inhibitor of an immune checkpoint protein, and a method of using the composition for treating a disease or disorder. In one embodiment, the immunogenic composition comprises TERT and at least one additional cancer antigen consensus sequence. Cancer antigen consensus sequences that can be included in the immunogenic composition include, but are not limited to, tyrosinase (Tyr), melanoma preferentially expressed antigen (PRAME), tyrosinase-related protein 1 (Tyrp1), cancer / testis antigen (NY-ESO-1), hepatitis B virus antigen, prostate-specific antigen (PSA), prostate-specific membrane antigen (PSMA), prostate six-transmembrane epithelial antigen of the prostate (STEAP), prostate stem cell antigen (PSCA), fibroblast activation protein (FAP), follicle-stimulating hormone receptor (FSHR), and Wilms tumor 1 antigen (WT-1). In one embodiment, the immunogenic composition of the present invention can provide a combination of cancer antigens for preventing or treating cancer in a subject in need of cancer prevention or treatment.
[0025] One method of designing the above nucleic acid and the amino acid sequence of the corresponding recombinant cancer antigen encoded thereby is to introduce mutations that alter specific amino acids in the overall amino acid sequence of the native cancer antigen. The introduction of mutations does not greatly modify the cancer antigen to the extent that the cancer antigen cannot be universally applied among mammalian subjects. For example, it can be applied to human or canine subjects. However, the introduction of such mutations changes the antigen to an extent that the resulting amino acid sequence exceeds the tolerance range, i.e., is changed sufficiently to be regarded as a foreign antigen for eliciting an immune response. Another method could be to create a recombinant cancer antigen having at least 85% to 99% amino acid sequence identity, at least 90% to 98% sequence identity, at least 93% to 98% sequence identity, or at least 95% to 98% sequence identity to the corresponding native cancer antigen. In some examples, the above recombinant cancer antigen has 95%, 96%, 97%, 98% or 99% amino acid sequence identity to the corresponding native cancer antigen. The above native cancer antigen is an antigen normally involved in a specific cancer or tumor. Depending on the cancer antigen, the consensus sequence of the cancer antigen can span across mammals, or within a subclass of the class, or across an entire viral strain or serotype. Some cancer antigens do not vary significantly from the wild-type of the amino acid sequence of the cancer antigen. Some cancer antigens have significantly different nucleic acid / amino acid sequences among species and thus cannot give rise to a consensus sequence. In these examples, a recombinant cancer antigen that elicits an immune response beyond the tolerance range is generated when the recombinant cancer antigen has at least 85% to 99% amino acid sequence identity, at least 90% to 98% sequence identity, at least 93% to 98% sequence identity, at least 95% to 98% sequence identity to the corresponding native cancer antigen. In some examples, the above recombinant cancer antigen has 95%, 96%, 97%, 98% or 99% amino acid sequence identity to the corresponding native cancer antigen. The above-mentioned efforts can be combined such that the final recombinant cancer antigen has similarity expressed as a percentage to the amino acid sequence of the unmutated cancer antigen as discussed above.
[0026] The recombinant cancer antigen described above can induce a response of antigen-specific T cells and / or high-titer antibodies, thereby inducing or eliciting an immune response directed against or reactive with a cancer or tumor expressing the antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can reduce or inhibit one or more immunosuppressive factors that promote the growth of a tumor or cancer expressing the antigen, such as, but not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, factors that upregulate CTLA-4, PD-1, MDSC, MCP-1, and immune checkpoint molecules.
[0027] The immunogenic composition may further be combined with antibodies against checkpoint inhibitors such as PD-1 and PDL-1 to increase the stimulation of both cellular and humoral immune responses. Using anti-PD-1 or anti-PDL-1 antibodies prevents PD-1 or PDL-1 from suppressing the response of T cells and / or B cells. Overall, designing cancer antigens recognized by the immune system helps overcome other forms of immunosuppression by cancer cells, and these immunogenic compositions can be used in combination with inhibitory or inhibitory therapies (such as anti-PD-1 and anti-PDL-1 antibody therapies) to further increase T cell and / or B cell responses.

To calculate this percentage, the two sequences are optimally aligned, the two sequences are compared over the specified region, the number of positions at which the identical residues of the two sequences occur is determined to obtain the number of matching positions, the number of matching positions is divided by the total number of positions in the specified region, and the result is multiplied by 100 to obtain the percent value of sequence identity. If the lengths of the two sequences are different, or if one or more attached ends are generated by the alignment and only a single sequence is included in the specified comparison region, the residues of the single sequence are included in the denominator but not in the numerator of the calculation. When comparing DNA and RNA, thymine (T) and uracil (U) can be considered equivalent. The calculation of identity can be performed manually or using computer sequence algorithms such as BLAST, BLAST 2.0, etc.
[0041] As used herein, "immune response" means that the host immune system, such as the mammalian immune system, is activated in response to the introduction of an antigen. This immune response can be in cellular or humoral form, or both.
[0042] As used herein, "nucleic acid" or "oligonucleotide" or "polynucleotide" means at least two nucleotides covalently linked to each other. By representing a single strand, the sequence of the complementary strand is also defined. Thus, a nucleic acid includes the complementary strand of the single strand being represented. Many variants of a given nucleic acid can be used for the same purpose as the given nucleic acid. Thus, a nucleic acid includes substantially identical nucleic acids and their complements. A single strand provides a probe that can hybridize to a target sequence under stringent hybridization conditions. Thus, a nucleic acid includes probes that hybridize under stringent hybridization conditions.
[0043] The nucleic acid can be single-stranded or double-stranded, and can also contain a part of the sequences of both double-stranded and single-stranded. The nucleic acid can be DNA, genomic DNA, cDNA, RNA, or a hybrid, and the nucleic acid can contain a combination of deoxyribonucleotides and ribonucleotides, and can contain a combination of bases including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine, hypoxanthine, isocytosine, and isoguanine. The nucleic acid can be obtained by chemical synthesis methods or recombinant methods.
[0044] As used herein, "functionally linked" means that a gene is expressed under the control of a promoter that is spatially connected to the gene. The promoter can be located 5' (upstream) or 3' (downstream) of the gene under its control. The distance between the promoter and the gene can be approximately the same as the distance between the gene controlled by the promoter and the promoter in the gene from which the promoter is derived. As is known in the art, changes in this distance can be accommodated without loss of promoter function.
[0045] As used herein, "peptide", "protein", or "polypeptide" can mean a linked sequence of amino acids, and can be natural, synthetic, or a modification of natural and synthetic or a combination thereof.
[0046] As used herein, a "promoter" refers to a synthetic or naturally occurring molecule capable of conferring, activating, or enhancing expression of a nucleic acid in a cell. A promoter can contain one or more specific transcriptional regulatory sequences to further enhance expression and / or modify its spatial and / or temporal expression. A promoter can also contain distal enhancer or repression elements, which can be located as far as thousands of base pairs from the transcription start site. Promoters can be derived from sources including viruses, bacteria, fungi, plants, insects, and animals. A promoter can regulate the expression of genetic components constitutively or differentially with respect to the cell, tissue, or organ in which expression occurs, or with respect to the developmental stage in which expression occurs, or can regulate the expression of genetic components in response to external stimuli, such as physiological stress, pathogens, metal ions, inducers, etc. Representative examples of promoters include a bacteriophage T7 promoter, a bacteriophage T3 promoter, an SP6 promoter, a lac operator promoter, a tac promoter, an SV40 late promoter, an SV40 early promoter, an RSV-TR promoter, a CMV IE promoter, an SV40 early promoter, an SV40 late promoter, and a CMV IE promoter.
[0047] "Signal peptide" and "leader sequence" are used interchangeably herein and refer to an amino acid sequence that can be attached to the amino terminus of a protein described herein. Generally, a signal peptide / leader sequence directs the localization of a protein. As used herein, a signal peptide / leader sequence can facilitate secretion of a protein from the cell in which it is produced. The signal peptide / leader sequence is often cleaved from the rest of the protein (often referred to as the mature protein) upon secretion from the cell. The signal peptide / leader sequence is attached to the amino terminus (i.e., N-terminus) of a protein.
[0048] As used herein, "stringent hybridization conditions" refers to conditions under which, for example, in a complex mixture of nucleic acids, a first nucleic acid sequence (e.g., a probe) hybridizes to a second nucleic acid sequence (e.g., a target). Since stringent conditions are sequence-dependent, they vary depending on the circumstances. Stringent conditions can be selected to be about 5-10 °C lower than the melting temperature (Tm) for a particular sequence at a given ionic strength and pH. Tm can be defined as the temperature at which 50% of the probe complementary to the target (under defined ionic strength, pH, and nucleic acid concentration) hybridizes to the target sequence at equilibrium (since the target sequence is present in excess, at Tm, 50% of the probe is occupied at equilibrium). Stringent conditions can have a sodium ion concentration of less than about 1.0 M at pH 7.0-8.3, e.g., a sodium ion concentration of about 0.01-1.0 M (or other salts), and a temperature of at least about 30 °C for short probes (e.g., 10-50 nucleotides) and at least about 60 °C for long probes (e.g., greater than about 50 nucleotides). Stringent conditions can also be achieved by the addition of destabilizing agents such as formamide. For selective or specific hybridization, the positive signal can be at least 2-10 times that of background hybridization. Examples of stringent hybridization conditions include the following: incubate at 42 °C in 50% formamide, 5× SSC, and 1% SDS. Or, incubate at 65 °C in 5× SSC, 1% SDS, and wash at 65 °C in 0.2× SSC, 0.1% SDS.
[0049] As used herein, "subject" means a mammal that desires or requires immunization with the immunogenic composition described herein. The mammal can be a human, chimpanzee, dog, cat, horse, cow, mouse, or rat.
[0050] As used herein, "substantially complementary" means that over a region of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 180, 270, 360, 450, 540 or more nucleotides or amino acids, the first sequence is at least 60%, 65%, 70%, 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identical to the complement of the second sequence, or that the two sequences hybridize under stringent hybridization conditions.
[0051] As used herein, "substantially identical" means that over a region of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 180, 270, 360, 450, 540 or more nucleotides or amino acids, the first sequence and the second sequence are at least 60%, 65%, 70%, 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identical, or, with respect to nucleic acids, when the first sequence is substantially complementary to the complement of the second sequence.
[0052] As used herein, "treatment" or "treating" can mean protecting an animal from a disease by preventing, suppressing, repressing, or completely eliminating the disease. Preventing a disease involves administering an immunogenic composition of the invention to an animal before the onset of the disease. Suppressing a disease involves administering an immunogenic composition of the invention to an animal after induction of the disease but before the clinical appearance of the disease. Suppressing a disease involves administering an immunogenic composition of the invention to an animal after the clinical appearance of the disease.
[0053] As used herein, "variant" with respect to nucleic acids means (i) a portion or fragment of a reference nucleotide sequence; (ii) the complement of a reference nucleotide sequence or a portion thereof; (iii) a nucleic acid that is substantially identical to a reference nucleic acid or its complement; or (iv) a nucleic acid that hybridizes under stringent conditions to a reference nucleic acid, its complement, or a substantially identical sequence thereof.
[0054] As used with respect to a peptide or polypeptide, a "variant" has an amino acid sequence that differs by amino acid insertions, deletions, or conservative substitutions, but retains at least one biological activity. A variant can also mean a protein having an amino acid sequence that is substantially identical to a reference protein and that retains at least one biological activity. Conservative substitution of an amino acid, i.e., substitution of one amino acid for another with similar properties (e.g., hydrophilicity, degree, and distribution of charged regions), is generally recognized in the art as involving minor changes. Such minor changes can be partially identified by considering the hydropathic index of the amino acids, as understood in the art. Kyte et al., J. Mol. Biol. 157:105-132 (1982). The hydropathic index of an amino acid is based on consideration of its hydrophobicity and charge. Amino acids with similar hydropathic indices can be substituted, and it is known in the art that protein function can still be maintained thereafter. In one aspect, amino acids having a hydropathic index of ±2 are substituted. Substitutions that result in a protein retaining a biological function can also be identified using the hydrophilicity of the amino acids. By considering the hydrophilicity of amino acids in relation to a peptide, the local maximum average hydrophilicity of the peptide can be calculated, which is a useful measure that has been reported to correlate well with antigenicity and immunogenicity. U.S. Patent No. 4,554,101 (this document is incorporated herein by reference in its entirety). As understood in the art, substituting amino acids with similar hydrophilicity values results in a peptide that retains biological activities such as immunogenicity. Substitutions can be made using amino acids whose hydrophilicity values are within ±2 of each other. Both the hydrophobic index and the hydrophilicity value of an amino acid are affected by the specific side chain of that amino acid. Consistent with these findings, amino acid substitutions that are compatible with biological function are understood to depend on the relative similarity of the amino acids, particularly the relative similarity of the side chains of the amino acids, which is revealed by hydrophobicity, hydrophilicity, charge, size, and other properties.
[0055] The variant may be a nucleic acid sequence that is substantially identical over the entire length of the complete gene sequence or a fragment thereof. The nucleic acid sequence may be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identical over the entire length of the gene sequence or a fragment thereof. The variant may be an amino acid sequence that is substantially identical over the entire length of the amino acid sequence or a fragment thereof. The amino acid sequence may be 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identical over the entire length of the amino acid sequence or a fragment thereof.
[0056] As used herein, "vector" means a nucleic acid sequence containing an origin of replication. The vector can be a viral vector, bacteriophage, bacterial artificial chromosome, or yeast artificial chromosome. The vector can be a DNA vector or an RNA vector. The vector is a self-replicating episomal vector and, in one embodiment, an expression plasmid. The vector can contain or incorporate one or more non-homologous nucleic acid sequences.

In one embodiment, the antigen encoded by the optimized consensus sequence can induce an immune response in a mammal. In one embodiment, the antigen encoded by the optimized consensus sequence can contain an epitope (s) that is particularly effective as an immunogen capable of inducing an immune response to the antigen.
[0058] The optimized consensus array can be a consensus array derived from two or more native TERT antigens. The optimized consensus array can have modifications for improving the consensus array and / or expression. Modifications include codon optimization, RNA optimization, addition of a Kozak sequence to enhance translation initiation efficiency, and / or addition of an immunoglobulin leader sequence to enhance immunogenicity. The TERT antigen encoded by the optimized consensus array can include a signal peptide such as, but not limited to, an immunoglobulin signal peptide including immunoglobulin E (IgE) or immunoglobulin (IgG) signal peptide. In some embodiments, the antigen encoded by the optimized consensus array can have a hemagglutinin (HA) tag.

Thus, in one embodiment, the invention relates to a nucleic acid sequence set forth in SEQ ID NO:47, SEQ ID NO:51, SEQ ID NO:55, or a fragment or homolog thereof, operably linked to a nucleotide sequence having a start codon at its 5' end. In one embodiment, the invention relates to an amino acid sequence set forth in SEQ ID NO:48, SEQ ID NO:52, or SEQ ID NO:56, or a fragment or homolog thereof, operably linked to an amino acid (e.g., methionine) encoded by the N-terminal start codon.
[0064] In one embodiment, the regulatory element is at least one stop codon. Thus, in one embodiment, the present invention relates to a nucleic acid sequence set forth in SEQ ID NO: 45, SEQ ID NO: 47, SEQ ID NO: 49, SEQ ID NO: 51, SEQ ID NO: 53, or SEQ ID NO: 55, or a fragment or homolog thereof, operably linked to a nucleotide sequence having at least one stop codon at the 3' end.

[0071] 3. Immunogenic composition In one embodiment, the immunogenic composition of the present invention can include a synthetic consensus TERT antigen, a fragment thereof, or a variant thereof. In one embodiment, the TERT antigen is a human TERT antigen (hTERT). hTERT is a human telomerase reverse transcriptase that synthesizes the TTAGGG tag at the ends of telomeres to prevent cell death due to chromosome shortening. Hyperproliferative cells may exhibit abnormally high expression of hTERT. Aberrant expression of hTERT may also occur in hyperproliferative cells infected with HCV and HPV. Therefore, immunotherapy against HPV and HCV can be improved by targeting cells that express hTERT at abnormal levels. The HPV and HCV antigens are described in more detail below. In one aspect, the hTERT cancer antigen can be further defined by U.S. Patent Application No. 14 / 139,660, filed December 23, 2013, the entire contents of which are incorporated herein by reference.
[0072] In one embodiment, the TERT antigen is a non-human TERT antigen. Non-human TERT antigens include, but are not limited to, mouse TERT (mTERT) and rhesus monkey TERT (rhTERT).
[0073] By expressing TERT in dendritic cells transfected with the TERT gene, antigen-specific CD8 + cytotoxic T cells can be induced, and CD4 + T cells can be elicited. Therefore, the use of hTERT expression in antigen-presenting cells (APCs) to delay aging and sustain the ability of APCs to present selected antigens can be used in immunotherapy, such as the methods described herein.
[0074] The TERT antigen can be associated with or expressed by any number of cancers, including but not limited to melanoma, prostate cancer, liver cancer, cervical cancer, recurrent respiratory papillomatosis (RRP), anal cancer, head and neck cancer, and blood cancer. Thus, when the TERT antigen described herein is included, such a vaccine can be used to treat subjects suffering from any number of cancers, including but not limited to melanoma, prostate cancer, liver cancer, cervical cancer, recurrent respiratory papillomatosis (RRP), anal cancer, head and neck cancer, and blood cancer.
[0075] The TERT antigen can induce or elicit an immune response that targets or is reactive against cancers or tumors that express the antigen by inducing antigen-specific T cells and / or a high-titer antibody response. In some embodiments, the induced or elicited immune response can be a cellular, humoral, or both cellular and humoral immune response. In some embodiments, the induced or elicited immune response can include the induction or secretion of interferon-γ (IFN-γ) and / or tumor necrosis factor α (TNF-α). In other embodiments, the induced or elicited immune response can reduce or inhibit one or more immunosuppressive factors that promote the growth of tumors or cancers that express antigens, including but not limited to factors that downregulate MHC presentation, factors that upregulate antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, CTLA-4, PD-1, MDSC, MCP-1, and immune checkpoint molecules described in more detail below.
[0076] The TERT antigen can include protein epitopes that make the TERT antigen particularly effective as an immunogen that can induce an anti-TERT immune response against it. The TERT antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The TERT antigen can include a consensus protein.
[0077] The nucleic acid sequence encoding the TERT antigen or the consensus TERT antigen can be optimized with respect to codon usage and the corresponding RNA transcript. The nucleic acid encoding the TERT antigen or the consensus TERT antigen can be codon and RNA optimized for expression. In some embodiments, the nucleic acid sequence encoding the TERT antigen or the consensus TERT antigen can include a Kozak sequence (e.g., GCC ACC) to enhance translation efficiency. The nucleic acid encoding the TERT antigen or the consensus TERT antigen can include multiple stop codons (e.g., TGA TGA) to enhance the efficiency of translation termination.
[0078] The nucleic acid encoding the TERT antigen or the consensus TERT antigen may encode the leader sequence of immunoglobulin E (IgE). The nucleic acid encoding the TERT antigen or the consensus TERT antigen can further encode the IgE leader sequence such that the amino acid sequence of the IgE leader sequence is linked to the amino acid sequence of the TERT antigen or the consensus TERT antigen by a peptide bond, respectively. The nucleic acid encoding the TERT antigen or the consensus TERT antigen may include the nucleotide sequence encoding the IgE leader sequence. In some embodiments, the nucleic acid encoding the TERT antigen or the consensus TERT antigen does not include or has no nucleotides encoding the IgE leader sequence.
[0079] In some embodiments, the nucleic acid encoding the TERT antigen or consensus TERT antigen may be a heterologous nucleic acid sequence and / or may have one or more heterologous nucleic acid sequences. The nucleic acid encoding the TERT antigen or consensus TERT antigen can be mutated relative to the wild-type TERT antigen such that one or more amino acids or residues in the amino acid sequence of the TERT antigen or consensus TERT antigen are each replaced with another amino acid or residue, i.e., substituted. By mutating the nucleic acid encoding the TERT antigen or consensus TERT antigen relative to the wild-type TERT antigen such that one or more residues in the amino acid sequence of the TERT antigen or consensus TERT antigen are each replaced with another residue, i.e., substituted, the immune system in the mammal to which the nucleic acid encoding the TERT antigen or consensus TERT antigen, the TERT antigen or consensus TERT antigen, or a combination thereof is administered can be made non-tolerant to TERT. The nucleic acid encoding the TERT antigen or consensus TERT antigen can be mutated relative to the wild-type TERT antigen such that both arginine 589, aspartic acid 1005, or both arginine 589 and aspartic acid 1005 in the amino acid sequence of the TERT antigen or consensus TERT antigen are replaced with tyrosine residues, i.e., substituted.
[0080] In one aspect, the TERT antigen may be the nucleic acid sequence of SEQ ID NO: 23 or SEQ ID NO: 57, which encode the amino acid sequences of SEQ ID NO: 24 and SEQ ID NO: 58, respectively. SEQ ID NO: 23 and SEQ ID NO: 57 encode the TERT antigen linked to the IgE leader sequence. In one embodiment, the TERT antigen can be linked to the IgE leader sequence and an HA tag. In other embodiments, the TERT antigen may not include and / or not be linked to the IgE leader sequence and / or HA tag.
[0081] In some embodiments, the TERT antigen may be a nucleic acid sequence having at least about 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identity over the full length of the nucleic acid sequence set forth in SEQ ID NO: 23 or SEQ ID NO: 57. In other embodiments, the TERT antigen may be a nucleic acid sequence encoding an amino acid sequence having at least about 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identity over the full length of the amino acid sequence set forth in SEQ ID NO: 24 or SEQ ID NO: 58.

[0119] The present invention relates to an anti-cancer immunogenic composition. The immunogenic composition may comprise one or more cancer antigens. The immunogenic composition can prevent tumor growth. The immunogenic composition can reduce tumor growth. The immunogenic composition can prevent tumor cell metastasis. Depending on the cancer antigen, the immunogenic composition can be intended to treat, but is not limited to, liver cancer, prostate cancer, melanoma, blood cancer, head and neck cancer, glioblastoma, recurrent respiratory papillomatosis, anal cancer, cervical cancer, and brain cancer.
[0120] The first step in developing the immunogenic composition is to identify cancer antigens that are not recognized by the immune system and are self-antigens. The identified cancer antigens are then modified from self-antigens to foreign antigens so that they can be recognized by the immune system. Redesigning the nucleic acid and amino acid sequences of recombinant cancer antigens from self-antigens to foreign antigens allows the immune system to exceed its tolerance range. To exceed this tolerance range, several redesign strategies, such as those described below, can be applied to cancer antigens.
[0121] The recombinant cancer antigen of the immunogenic composition is not recognized as a self-antigen and thus exceeds the tolerance range. Deviation from the tolerance range induces a response of antigen-specific T cells and / or high-titer antibodies, thereby inducing or eliciting an immune response directed against or reactive to the cancer or tumor expressing the antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can reduce or inhibit one or more immunosuppressive factors that promote the growth of the tumor or cancer expressing the antigen, including, but not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, factors that upregulate CTLA-4, PD-1, MDSC, MCP-1, and immune checkpoint molecules.
[0122] In certain embodiments, the immunogenic composition can mediate tumor elimination or prevent the growth of tumor cells by inducing the following. That is, (1) a humoral immune response via B cells that blocks the production of monocyte chemoattractant protein-1 (MCP-1), thereby inhibiting myeloid derived suppressor cells (MDSC) and suppressing tumor growth, and (2) CD8 to attack and kill tumor cells +such as an increase in cytotoxic T lymphocytes (CTLs), (3) an increase in helper T cell responses, and (4) an increase in inflammatory responses mediated by IFN-γ and TFN-α, or a combination of the above items. The above immunogenic composition can increase the tumor-free survival rate by 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, and 45%. The above immunogenic composition can reduce the tumor size by 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, and 60% after immunization. The above immunogenic composition can prevent and inhibit an increase in monocyte chemoattractant protein-1 (MCP-1), a cytokine secreted by myeloid-derived suppressor cells. The above immunogenic composition can increase the tumor survival rate by 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, and 60%.

The selection of the antigen-binding portion of the present invention is determined according to the specific type of cancer to be treated. Tumor antigens are well-known in the art and include, for example, glioma-associated antigen, carcinoembryonic antigen (CEA), β-human chorionic gonadotropin, α-fetoprotein (AFP), lectin-reactive AFP, thyroglobulin, RAGE-1, MN-CA IX, human telomerase reverse transcriptase, RU1, RU2(AS), intestinal carboxylesterase, mut hsp70-2, M-CSF, prostase, prostate-specific antigen (PSA), PAP, NY-ESO-1, LAGE-1a, p53, prostain, PSMA, Her2 / neu, survivin and telomerase, prostate cancer tumor antigen-1 (PCTA-1), MAGE, ELF2M, neutrophil elastase, ephrin B2, CD22, insulin growth factor (IGF)-I, IGF-II, IGF-I receptor and mesothelin.
[0136] In one embodiment, the tumor antigen comprises one or more antigenic cancer epitopes associated with malignant tumors. Malignant tumors express many proteins that can serve as target antigens for immune attack. These molecules include, but are not limited to, tissue-specific antigens such as MART-1, tyrosinase, and GP100 in melanoma, and prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) in prostate cancer. Other target molecules belong to the group of transformation-associated molecules, such as the oncogene HER-2 / Neu / ErbB-2. Yet another group of target antigens is carcinoembryonic antigen (CEA), such as oncofetal antigen. In B-cell lymphomas, tumor-specific idiotypic immunoglobulins constitute truly tumor-specific immunoglobulin antigens unique to individual tumors. B-cell differentiation antigens, such as CD19, CD20, and CD37, are other candidate target antigens in B-cell lymphomas. Some of these antigens (CEA, HER-2, CD19, CD20, idiotypes) have been used as targets for passive immunotherapy using monoclonal antibodies, but with limited success.
[0137] The type of tumor antigen referred to in the present invention may be a tumor-specific antigen (TSA) or a tumor-associated antigen (TAA). TSAs are unique to tumor cells and do not occur in other cells in the body. TAA-associated antigens are not unique to tumor cells and are also expressed in normal cells under conditions that cannot induce a state of immune tolerance to the antigen. Antigen expression in tumors can occur under conditions that allow the immune system to respond to the antigen. TAA may be an antigen expressed in normal cells during fetal development, when the immune system is immature and unable to respond, or it may be an antigen that is normally present at very low levels in normal cells but expressed at significantly higher levels in tumor cells.
[0138] Non-limiting examples of TSA antigens or TAA antigens include the following: differentiation antigens such as MART-1 / MelanA (MART-I), gp100 (Pmel 17), tyrosinase, TRP-1, TRP-2, and tumor-specific multi-family antigens such as MAGE-1, MAGE-3, BAGE, GAGE-1, GAGE-2, p15; fetal antigens overexpressed such as CEA; tumor genes overexpressed and mutated tumor suppressor genes such as p53, Ras, HER-2 / neu; unique tumor antigens generated by chromosomal translocation; BCR-ABL, E2A-PRL, H4-RET, IGH-IGK, MYL-RAR, etc.; and viral antigens such as Epstein-Barr virus antigen EBVA and human papillomavirus (HPV) antigens E6 and E7. Other large protein-based antigens include TSP-180, MAGE-4, MAGE-5, MAGE-6, RAGE, NY-ESO, p185erbB2, p180erbB-3, c-met, nm-23H1, PSA, TAG-72, CA19-9, CA72-4, CAM17.1, NuMa, K-ras, β-catenin, CDK4, Mum-1, p15, p16, 43-9F, 5T4, 791Tgp72, alpha-fetoprotein, β-HCG, BCA225, BTAA, CA125, CA15-3\CA27.29\BCAA, CA195, CA242, CA-50, CAM43, CD68\P1, CO-029, FGF-5, G250, Ga733\EpCAM, HTgp-175, M344, MA-50, MG7-Ag, MOV18, NB / 70K, NY-CO-1, RCAS1, SDCCAG16, TA-90\Mac-2 binding protein\cyclophilin C-related protein, TAAL6, TAG72, TLP, and TPS.
[0139] One or more antibodies targeting the TERT antigen and optionally one or more immune checkpoint proteins can be associated with or combined with a tumor antigen, or a fragment or variant thereof. A cancer marker is a known protein that is present in or upregulated in specific cancer cells. A cancer vaccine can be produced by a method of generating an antigen representative of such a marker that breaks tolerance to self. Such a cancer vaccine can include the TERT antigen, and optionally one or more antibodies targeting one or more immune checkpoint proteins to enhance the immune response, and optionally one or more additional tumor antigens. The following are some exemplary tumor antigens.
[0140] (1) Tyrosinase (Tyr) The immunogenic composition of the present invention can include the cancer antigen tyrosinase (Tyr), a fragment thereof, or a variant thereof. Tyrosinase is a copper-containing enzyme having tyrosine hydroxylase and dopa oxidase catalytic activities that can be found in microorganisms, plants, and animal tissues. Specifically, tyrosinase catalyzes the production of melanin or other pigments by the oxidation of phenols such as tyrosine. Mutations in the TYR gene result in oculocutaneous albinism in mammals, and non-pathological gene polymorphisms in the TYR gene contribute to changes in skin pigmentation.
[0141] Furthermore, in cancers or tumors such as melanoma, tyrosinase can become uncontrolled, leading to an increase in melanin synthesis. Thus, tyrosinase can be a cancer antigen associated with melanoma. In subjects suffering from melanoma, tyrosinase can be a target for cytotoxic T cell recognition. However, in some cases, the immune response against cancers or tumors (including melanoma) is suppressed, resulting in a microenvironment that supports tumor formation and / or growth, and thus can lead to disease progression.
[0142] Immunosuppression can be promoted by myeloid-derived suppressor cells (MDSC), which are a heterogeneous population of immature macrophages, granulocytes, dendritic cells, and myeloid cells. Myeloid cells can be a heterogeneous population of myeloid progenitor cells and immature myeloid cells (IMC). Markers of MDSC include the expression of Gr-1 and CD11b (i.e., Gr-1 + and CD11b + cells).
[0143] The circulation of MDSC is increased due to chronic infection, and the expansion of MDSC numbers can be associated with autoimmunity and inflammation. In particular, the proliferation of MDSC (presence in tumor or cancerous tissue) promotes tumor growth and avoidance of and / or immune modulation from immune detection, and thus, MDSC can affect the immune response to anti-cancer vaccines.
[0144] MDSC is regulated by Regulator of G-protein signaling 2 (Rgs2), which can be highly expressed in tumor-derived MDSC. Rgs2 can also be widely expressed in various cells such as myeloid cells, for example. MDSC from mice with tumors can exhibit different effects compared to MDSC from mice without tumors. One such difference can be the upregulation of chemokine MCP-1 production, which is secreted by MDSC. MCP-1 can promote cell migration through signal transduction via CCR2, a G-protein coupled receptor (GPCR) present on monocytes, endothelial cells, and T cells. Thus, MCP-1 can cause the migration of endothelial cells and thereby promote angiogenesis. Blocking of MCP-1 via neutralizing antibodies can inhibit angiogenesis and thus lead to a reduction in tumor metastasis and an increase in survival rate. Thus, MCP-1 can be considered an angiogenesis factor. In addition to secreting MCP-1, MDSC secrete growth factors and thereby can further contribute to tumor growth.
[0145] The Tyr antigen can induce antigen-specific T cells and / or high-titer antibody responses, thereby inducing or eliciting an immune response directed against or reactive to a cancer or tumor expressing said antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can include, but is not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, and factors that upregulate immune checkpoint molecules such as CTLA-4, PD-1, MDSC, MCP-1, and the like, one or more immunosuppressive factors that promote the growth of a tumor or cancer expressing said antigen can be reduced or inhibited, and the immune checkpoint molecules will be described in more detail later.
[0146] As demonstrated herein, the Tyr antigen induces antigen-specific T cells and high-titer antibody responses against cancer cells or tumor cells (e.g., melanoma cells). Specifically, the Tyr antigen (1) blocks the production of monocyte chemoattractant protein-1 (MCP-1), thereby inhibiting myeloid-derived suppressor cells (MDSC) and generating antibodies that suppress tumor growth through a humoral immune response mediated by B cell responses, (2) attacks and kills tumor cells for CD8 +It is an important target for immune-mediated tumor elimination by inducing an increase in cytotoxic T lymphocytes (CTLs) such as, (3) an increase in helper T cell responses, and (4) an increase in inflammatory responses mediated by IFN-γ and TFN-α, or a combination of the above items. Thus, an immunogenic composition containing a Tyr antigen (e.g., a consensus Tyr antigen, which will be described in more detail later) prevents immunosuppression by reducing the number of MDSCs present in cancer or tumor tissue, and blocks angiogenesis of cancer or tumor tissue by reducing the production or secretion of MCP-1. Therefore, these immunogenic compositions provide a protective immune response against tumor formation and tumor growth. Accordingly, any user can design the immunogenic composition of the present invention to contain a Tyr antigen that provides broad immunity against tumor formation, tumor metastasis, and tumor growth.
[0147] The Tyr antigen can contain protein epitopes that make the antigen particularly effective as an immunogen capable of inducing an anti-Tyr immune response against it. The Tyr antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The Tyr antigen can include a consensus protein.
[0148] The nucleic acid sequence encoding the consensus Tyr antigen can be optimized with respect to codon usage frequency and the corresponding RNA transcript. The nucleic acid encoding the consensus Tyr antigen can be codons and RNA optimized for expression. In some embodiments, the nucleic acid sequence encoding the consensus Tyr antigen can include a Kozak sequence (e.g., GCC ACC) to improve the efficiency of translation. The nucleic acid encoding the consensus Tyr antigen can include multiple stop codons (e.g., TGA TGA) to improve the efficiency of translation termination.
[0149] The nucleic acid encoding the consensus Tyr antigen can also encode an immunoglobulin E (IgE) leader sequence. The nucleic acid encoding the consensus Tyr antigen can further encode the IgE leader sequence such that the amino acid sequence of the IgE leader sequence is linked to the amino acid sequence of the consensus Tyr antigen by a peptide bond.

[0164] (2) Tyrosinase-related protein 1 (TYRP1) The immunogenic composition of the present invention can include the cancer antigen tyrosinase-related protein 1 (TYRP1), a fragment thereof, or a variant thereof. TYRP1 is encoded by the TYRP1 gene and is a 75 kDa transmembrane glycoprotein that is expressed in both normal and malignant melanogenic cells and melanoma cells. TYRP1, like tyrosinase, contains a modified called the M box that can bind to the microphthalmia transcription factor (MITF), and MITF plays a central role in melanogenic cells in pigmentation, cell proliferation, and differentiation. TYRP1 can help stabilize tyrosinase and can form heterodimers, and the dimers can prevent early death of melanogenic cells by attenuating tyrosinase-mediated cytotoxicity.
[0165] As described above for tyrosinase, tyrosinase-related protein 1 (TYRP-1) is also involved in the synthesis and pigment mechanism of melanin in melanogenic cells and can be recognized by the immune system in subjects affected by melanoma. Thus, TYRP-1 can be an antigen related to melanoma.

[0167] The TYRP-1 antigen can include protein epitopes that make the antigen particularly effective as an immunogen capable of inducing an anti-TYRP-1 immune response against the antigen.

[0184] (3) Tyrosinase-related protein 2 (TYRP2) The immunogenic composition of the present invention can comprise the cancer antigen tyrosinase-related protein 2 (TYRP2, also known as dopachrome tautomerase (DCT)), a fragment thereof, or a variant thereof. TYRP2 / DCT is a protein encoded by the TYRP2 / DCT gene and composed of 519 amino acids, and is expressed in both normal and malignant melanogenic cells and melanoma cells. TYRP2 / DCT is a well-characterized melanogenic cell-specific enzyme that functions, in cooperation with tyrosinase and TYRP1, in the conversion of L-tyrosine to melanin in melanogenic cells. DCT, specifically, catalyzes the tautomerization of the melanin precursor L-dopachrome to 5,6-dihydroindole-2-carboxylic acid (DHICA), which is subsequently oxidized by TYRP1 (as described above) to form eumelanin. Studies have shown that TYRP2 / DCT can be a mediator of drug resistance in melanoma cells, having specificity for DNA-damaging agents. Since TYRP2 / DCT has often been reported to be highly expressed in melanoma, this melanogenic cell-specific enzyme plays an important role in contributing to the intrinsic drug resistance phenotype of melanoma to various anti-cancer DNA-damaging agents.
[0185] As described above for tyrosinase, tyrosinase-related protein 2 (TYRP-2) can also be involved in the synthesis of melanin and can be recognized by the immune system in subjects affected by melanoma. Furthermore, TYRP-2 can mediate drug resistance in melanoma cells. Thus, TYRP-2 can be an antigen associated with melanoma.
[0186] The TYRP-2 antigen can induce an antigen-specific T cell and / or high-titer antibody response, thereby inducing or eliciting an immune response that targets or is reactive to a cancer or tumor expressing the above antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response includes, but is not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, factors that upregulate CTLA-4, PD-1, MDSC, MCP-1, and immune checkpoint molecules, etc. One or more immunosuppressive factors that promote the growth of tumors or cancers expressing the above antigen can be reduced or inhibited, and the immune checkpoint molecules will be described in more detail later.
[0187] The TYRP-2 antigen can contain a protein epitope that makes the antigen particularly effective as an immunogen capable of inducing an anti-TYRP-2 immune response against the antigen. The TYRP-2 antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The TYRP-2 antigen can include a consensus protein.

In some embodiments, the nucleic acid encoding the consensus TYRP-2 antigen does not have, i.e., does not include, the nucleotide sequence encoding the IgE leader sequence.

[0204] (4) Melanoma-associated Antigen 4 (MAGEA4) The immunogenic composition of the present invention can contain a cancer antigen melanoma-associated antigen 4 (MAGEA4), a fragment thereof, or a variant thereof. MAGE-A4 is a protein encoded by the MAGE-A4 gene and composed of 317 amino acids, and is expressed in male germ cells and tumor cells of various histological types such as digestive tract cancer, esophageal cancer, and lung cancer. MAGE-A4 binds to a tumor protein, ganp. This specific binding to MAGE-A4 is mediated by its C-terminus. Studies have shown that exogenous MAGE-A4 can partially inhibit the adhesion-independent growth of ganp-overexpressing cells in vitro and can inhibit the formation of tumors metastasized from these cells in nude mice. This inhibition depends on the binding between MAGE-A4 and ganp, suggesting that the interaction between ganp and MAGE-A4 inhibits ganp-mediated carcinogenesis. The expression of MAGE in tumor tissues is a result rather than a cause of tumorigenesis, and the MAGE gene appears to be involved in the immune process by targeting and destroying early tumor cells.
[0205] Melanoma-associated antigen 4 (MAGEA4) may be involved in embryonic development and tumor transformation and / or progression. MAGEA4 is normally expressed in the testis and placenta. However, MAGEA4 can be expressed in many different types of tumors, such as melanoma, head and neck squamous cell carcinoma, lung cancer, and breast cancer. Therefore, MAGEA4 may be an antigen associated with various tumors.
[0206] The MAGEA4 antigen can induce antigen-specific T cells and / or high-titer antibody responses, thereby inducing or eliciting an immune response that targets or is reactive to cancer or tumors expressing said antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can include, but is not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, factors that upregulate immune checkpoint molecules such as CTLA-4, PD-1, MDSC, MCP-1, and one or more immunosuppressive factors that promote the growth of tumors or cancers expressing said antigen can be reduced or inhibited, and the immune checkpoint molecules will be described in more detail later.
[0207] The MAGEA4 antigen can include protein epitopes that make the antigen particularly effective as an immunogen capable of inducing an anti-MAGEA4 immune response against the antigen. The MAGEA4 antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The MAGEA4 antigen can include a consensus protein.
[0208] The nucleic acid sequence encoding the consensus MAGEA4 antigen can be optimized with respect to codon usage frequency and the corresponding RNA transcript. The nucleic acid encoding the consensus MAGEA4 antigen can be codons and RNA optimized for expression.

[0224] (5) Growth hormone releasing hormone (GHRH) The immunogenic composition of the present invention can comprise a cancer antigen growth hormone-releasing hormone (GHRH, also known as growth-hormone-releasing factor (GRF or GHRF) or somatocrinin), a fragment thereof, or a variant thereof. GHRH is a 44-amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus. GHRH is secreted by the hypothalamus and stimulates the release of growth hormone from the pituitary gland, growth, metabolism, and the release of regulators of body structure. GHRH also stimulates the production of growth hormone. Antagonists of GHRH inhibit the growth of various cancers such as, for example, osteosarcoma, glioblastoma, prostate cancer, renal cancer, pancreatic cancer, colorectal cancer, and breast cancer. Thus, GHRH can be an antigen associated with various tumors.
[0225] The GHRH antigen can induce an antigen-specific T cell and / or high-titer antibody response, thereby inducing or eliciting an immune response directed against or reactive to a cancer or tumor expressing said antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can reduce or inhibit one or more immunosuppressive factors that promote the growth of a tumor or cancer expressing said antigen, such as, but not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, factors that upregulate CTLA-4, PD-1, MDSC, MCP-1, and immune checkpoint molecules, which are described in more detail later.
[0226] The GHRH antigen can include protein epitopes that make the antigen particularly effective as an immunogen capable of inducing an anti-GHRH immune response that counteracts the antigen. The GHRH antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The GHRH antigen can include a consensus protein.

[0243] (6) MART-1 / Melan-A The immunogenic composition of the present invention can include the cancer antigen MART-1 (also known as Melan-A), its fragments, or its variants. MART-1 is encoded by the MLANA gene, is a protein of 118 amino acids, contains a single transmembrane domain, and is expressed in most melanoma cells. MART-1 forms a complex with structural proteins and affects its expression, stability, transport, and the processing necessary for the structure and maturation of melanosomes. Therefore, MART-1 is essential for regulating mammalian pigmentation. Defects in melanosome maturation have been associated with susceptibility to cancer. MART-1 can be expressed in a number of cancers, including but not limited to melanoma.
[0244] Melan-A, also known as melanoma antigen recognized by T cells (MART-1), is a differentiation antigen of melanocytes and can be present in normal skin, retina, and melanocytes. Melan-A can be associated with the endoplasmic reticulum and melanosomes. Melan-A can be recognized by cytotoxic T cells as an antigen on melanoma cells, but can also be associated with other tumors of melanocyte origin or with their differentiation, such as clear cell sarcoma and melanotic schwannoma (i.e., cells having melanosomes). Therefore, Melan-A can be an antigen associated with various tumors derived from cells having melanosomes.
[0245] The Melan-A antigen can induce antigen-specific T cell and / or high-titer antibody responses, thereby inducing or eliciting an immune response that targets or is reactive to cancer or tumors expressing the above antigen. In some embodiments, the induced or elicited immune response can be a cellular immune response, a humoral immune response, or both a cellular and humoral immune response. In some embodiments, the induced or elicited cellular immune response can include the induction or secretion of interferon-gamma (IFN-γ) and / or tumor necrosis factor alpha (TNF-α). In other embodiments, the induced or elicited immune response can include, but is not limited to, factors that downregulate presentation by MHC, antigen-specific regulatory T cells (Tregs), cytokines such as PD-L1, FasL, IL-10, and TGF-β, tumor-associated macrophages, tumor-associated fibroblasts, soluble factors produced by immunosuppressive cells, and factors that upregulate one or more immunosuppressive factors that promote the growth of tumors or cancers expressing the above antigen, such as CTLA-4, PD-1, MDSC, MCP-1, and factors that upregulate immune checkpoint molecules, which will be described in more detail later.
[0246] The Melan-A antigen can contain protein epitopes that make the antigen particularly effective as an immunogen capable of inducing an anti-Melan-A immune response against the antigen. The Melan-A antigen can include the full-length translation product, variants thereof, fragments thereof, or combinations thereof. The Melan-A antigen can include a consensus protein.
