Abstract
Description
Technical Field
[0001] This disclosure belongs to the field of mRNA vaccine technology, specifically relating to a herpes zoster mRNA vaccine, its preparation method, and its application. Prior Technology
[0002] Shingles is an infectious skin disease caused by the reactivation of the varicella-zoster virus (VZV), which has been dormant in the dorsal root ganglia of the spinal cord or cranial nerve ganglia for a long time. Shingles is a common dermatological condition, often accompanied by neuropathic pain in addition to skin lesions. It is more common in older adults, those with suppressed or deficient immune systems, and is more prevalent in spring and autumn. The incidence rate increases significantly with age.
[0003] After a person recovers from chickenpox, varicella-zoster virus (VZV) is not completely eradicated. Instead, it remains latent in the cranial ganglia, dorsal root ganglia, and autonomic ganglia throughout the nerve axis, persisting throughout life. Following chickenpox infection with VZV, the body produces specific antibodies against VZV and T-cell-mediated cellular immunity (such as CD4+ / CD8+ / memory T cells). These two immune mechanisms play a crucial role in maintaining latent VZV infection and preventing shingles. With age or the occurrence of external or internal factors that suppress the body's immunity, VZV can spontaneously reactivate, triggering herpes zoster (HZ).
[0004] Common triggering factors for shingles include age (such as old age), cellular immune deficiency, genetic susceptibility, trauma, systemic diseases (such as diabetes, kidney disease, etc.), excessive mental stress, fatigue, etc. Unlike chickenpox in children, shingles in adults (elderly) is more likely to cause sequelae, the most common of which is postherpetic neuralgia (PHN), which can cause pain for 3 to 12 months after shingles has healed.
[0005] Shingles and postherpetic neuralgia are both common and frequently occurring diseases. Chronic pain caused by shingles (postherpetic neuralgia) and other complications, commonly known as "shingles," "herpes zoster," etc., severely impact patients' quality of life. The elderly and those with weakened immune systems are frequently affected by these complications. Due to the unclear pain mechanism, postherpetic neuralgia remains one of the most difficult-to-treat pain conditions.
[0006] Shingles has two notable characteristics: a high rate of transmission and significant suffering for sufferers. Data from European and American surveys show that the annual incidence of shingles is generally 2-6 per 1,000 people. The incidence increases with age. Statistical surveys show that the incidence rate in the 10-49 age group is approximately 4 per 1,000, while the incidence rate in the over 75 age group is as high as 14 per 1,000. Furthermore, women are slightly more likely to contract shingles than men. Currently, the global incidence of shingles is on the rise. Surveys from 1994 to 2018 show that the annual incidence rate of shingles is increasing by 3.1% annually, with a particularly significant increase in the 20-49 age group.
[0007] China has not included shingles in the category of Class A and B notifiable infectious diseases, and there are relatively few related epidemiological studies on the entire population. Statistics show that approximately 99.5% of adults aged 50 and above in China harbor the VZV virus, with about 1.56 million new cases annually. The average annual incidence rate of shingles in the 50-60 age group in China is 2.66‰, while the average annual incidence rate in the 80+ age group is as high as 8.55‰. The incidence of postherpetic neuralgia (PHN) also increases with age; studies show that the incidence rate of PHN among elderly shingles patients in China is 18.8%, reaching 31.7% in those over 75 years of age.
[0008] Vaccines are the most effective way to prevent shingles. The main technological approaches involved in shingles vaccine development include live attenuated vaccines, recombinant protein vaccines, adenovirus vector vaccines, and mRNA vaccines.
[0009] Globally, there are currently only four vaccines available for the prevention of shingles: Merck's live attenuated vaccine Zostavax® (discontinued), GlaxoSmithKline's (GSK) recombinant vaccine Shingrix®, SK Chemicals' SkyZoster® (sold only in South Korea), and the recently launched live attenuated vaccine from China's BEHC Biotechnology. Merck's Zostavax® was the world's first approved shingles vaccine, launched in the US and Europe in 2006. However, due to its low protective efficacy (approximately 70% protection against shingles), it was unsuitable for people with immunosuppression or immune system disorders, severely limiting its application, and production was discontinued in 2018. GlaxoSmithKline's (GSK) recombinant protein vaccine, Shingrix®, was launched in the US in 2017, in Europe in 2018, and applied for marketing approval in China in 2019. Global sales of this vaccine reached $2.4 billion in 2021 and $3.2 billion in 2022, consistently ranking among the top ten best-selling vaccines globally for several years. However, as a protein subunit vaccine, the use of GSK's special adjuvant makes it expensive and difficult to increase production capacity. More importantly, it has significant side effects, with a significantly higher incidence of adverse reactions compared to live attenuated vaccines.
[0010] mRNA vaccines represent the third generation of vaccine technology, following traditional vaccines and protein subunit vaccines. After entering human cells via a specific delivery system, mRNA vaccines utilize the body's own cells to translate mRNA into proteins. These proteins are expressed as antigens specific to the virus, recognized as foreign antigens by antigen-presenting cells (APCs). This drives the maturation of dendritic cells (DCs), which in turn activate B cells and T cells to produce a strong immune response, triggering both humoral and cellular immune responses. mRNA vaccines break through the traditional immune activation model by innovatively utilizing the body's own cells to produce antigens, thereby activating dual-specific immunity, forming immune memory, and providing more durable specific immunity. The greatest advantage of mRNA vaccines is that once the antigen gene sequence of the pathogen is known, mRNA vaccines can be developed quickly. The rapid design and construction of mRNA vaccine technology, its high responsiveness to viral mutations, and its efficient, universal, total synthetic production platform, along with its ease of standardization, result in short production cycles and relatively simple processes, enabling rapid mass production of mRNA vaccines.
[0011] Compared with traditional vaccines, shingles mRNA vaccines have the following advantages: 1) They are non-infectious and non-integrative reagents, eliminating the risk of infection or insertional mutations; 2) mRNA vaccines activate specific immunity in the body by expressing antigens, resulting in more durable and effective specific immunity; 3) mRNA vaccines can be stably delivered into cells for efficient intracellular expression; 4) mRNA vaccine production can be subject to rigorous quality control.
[0012] gE is the main target protein in shingles vaccine development and is one of the most abundant glycoproteins in VZV, playing a crucial role in viral replication and viral transmission between ganglion cells. As a highly glycosylated type I membrane protein, gE can be transported between the endoplasmic reticulum (ER), the trans-Golgi network (TGN), and endosomes.
[0013] Based on the above problems, in order to further reduce the risk of shingles in people with weakened immune systems, there is an urgent need to provide a novel mRNA vaccine to prevent VZV, which can significantly enhance humoral and cellular immunity after vaccination. Summary of the Invention
[0014] This invention provides a shingles mRNA vaccine that can safely guide the body's cellular mechanisms to produce virtually any protein of interest, from natural proteins to antibodies and other entirely novel proteins that may have preventative activity both inside and outside cells. The shingles mRNA vaccine of this disclosure can be used to elicit a balanced immune response against VZV, encompassing both cellular and humoral immunity, without the many risks associated with attenuated virus vaccination.
[0015] RNA (e.g., mRNA) vaccines are available in a variety of situations depending on the prevalence of infection or the degree or level of unmet medical need. RNA (e.g., mRNA) vaccines can be used to prevent VZV of various genotypes, strains, and isolates. The advantage of RNA (e.g., mRNA) vaccines lies in their ability to produce significantly higher antibody titers and earlier responses compared to commercially available antiviral treatments. While not wishing to be bound by theory, it is believed that, like mRNA polynucleotides, RNA vaccines are better designed to produce appropriate protein conformations through translation when the RNA vaccine is assigned to natural cellular mechanisms. Unlike conventional vaccines manufactured in vitro and capable of triggering adverse cellular responses, RNA (e.g., mRNA) vaccines are delivered to cellular systems in a more natural manner.
[0016] Based on the important structure and biological function of the VZV gE protein, this invention innovatively designed a series of mRNA vaccine candidate antigens and compared their immunogenicity with existing mRNA vaccines (e.g., antigen YK-VZV-007, see CN108472309A; and the marketed recombinant subunit vaccine Shingrix®). Several shingles mRNA candidate vaccines with novel antigen structures and superior immunogenicity were successfully screened, which provides a foundation for the successful development of shingles mRNA vaccines.
[0017] Based on wild-type VZV gE glycoprotein, this application combines ribonucleic acid encoding multiple VZV gE glycoprotein variants through specific methods (including sequence truncation, site mutation, and / or sequence deletion), and provides novel mRNA vaccines for the prevention of VZV. Experiments have shown that vaccination can significantly enhance humoral and cellular immunity, including: increasing the content of IgG antibodies against VZV gE protein, increasing the number of immune cells (including CD4+ and CD8+ that secrete IFN-γ+ and / or IL-2+), and promoting the secretion of cytokines (including IFN-γ+ and IL-2+) by immune cells in a herpes zoster mRNA vaccine.
[0018] The mRNA vaccines provided herein may include at least one VZV glycoprotein RNA polynucleotide provided in the appended sequence listing, or fragments, homologs (e.g., having at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% identity), or variants or derivatives thereof.

This also includes mutations in one or more motifs associated with targeting the Golgi apparatus or trans-Golgi network (TGN), resulting in a reduction in the VZV gE polypeptide targeting or localizing to the Golgi apparatus or TGN. In particular, the inventors have unexpectedly discovered that the motifs associated with gE protein localization to the Golgi apparatus or trans-Golgi network include the "A568Y569R570V571" motif (specifically, its mutated antigenic sequence is such as YK-VZV-011 (SEQ ID NO:35), especially the A568D and / or Y569K mutations).
[0028] Furthermore, in some embodiments, the VZV gE variant may have a Y582A / G mutation, or a Y569K / A mutation, or a combination of Y582G and Y569A mutations. Other mutation types also include phosphorylated acidic motif mutations such as those at the S593EST596DT598 (SEQ ID NO:182) site.

[0033] In some implementations, the VZV gE variant is a full-length polypeptide having the sequence A593EA595A596DA598 (SEQ ID NO:183).
[0034] In some embodiments, the VZV gE variant is a full-length or truncated polypeptide having the sequence A593EA595A596DA598 (SEQ ID NO:183) and having a Y582G mutation, or a Y569K mutation, or a combination of Y582G and Y569K mutations.

[0047] This application is the first to discover: This application, based on wild-type VZV gE glycoprotein, combines several ribonucleic acids encoding VZV gE glycoprotein variants through specific methods (including sequence truncation, site mutation, and / or sequence deletion), providing a novel mRNA vaccine for VZV prevention. Experiments have demonstrated that vaccination significantly enhances humoral and cellular immunity, including: increasing the level of IgG antibodies against VZV gE protein, increasing the number of immune cells (including CD4+ and CD8+ secreting IFN-γ+ and / or IL-2+), and promoting the secretion of cytokines (including IFN-γ+ and IL-2+) by immune cells in a herpes zoster mRNA vaccine. Specifically, this application includes the following findings and results: 1. By performing Western spectroscopy on 43 designed VZV gE antigen variants... Blot analysis showed that all 39 antigen sequences exhibited significant protein expression, including YK-VZV-001, YK-VZV-003, YK-VZV-009, YK-VZV-010, YK-VZV-011, YK-VZV-012, YK-VZV-013, YK-VZV-014, YK-VZV-015, YK-VZV-016, YK-VZV-017, YK-VZV-018, YK-VZV-019, YK-VZV-020, YK-VZV-021, YK-VZV-022, YK-VZV-023, YK-VZV-024, YK-VZV-025, YK-VZV-026, and YK-V ZV-027, YK-VZV-028, YK-VZV-029, YK-VZV-030, YK-VZV-031, YK-VZV-032, YK-VZV-033, YK-VZV-034, YK-VZV-035, YK-VZV-036, YK-VZV-037, YK-VZV-038, YK-VZV-039, YK-VZV-040, YK-VZV-044, as well as YK-VZV-004 (Comparative Example 1), YK-VZV-006 (Comparative Example 2), YK-VZV-045 (Comparative Example 3), and YK-VZV-007 (Comparative Example 4) can be used as effective candidate antigens for the next step of immunogenicity screening and evaluation. 2. Based on the above 39 sequences, the following 14 variants were extracted using the gE-specific antibody IgG titer results on day 42: YK-VZV-009, YK-VZV-011, YK-VZV-013, YK-VZV-014, YK-VZV-010, YK-VZV-012, YK-VZV-018, and YK-VZV-020. YK-VZV-030, YK-VZV-031, YK-VZV-038, YK-VZV-021, YK-VZV-024, YK-VZV-028 and four control sequences YK-VZV-004 (Comparative Example 1), YK-VZV-006 (Comparative Example 2), YK-VZV-045 (Comparative Example 3), and YK-VZV-007 (Comparative Example 4). The above sequences were 3.3 to 5.3 times larger than the Shingrix® positive control and 1.8 to 2.8 times larger than the YK-VZV-007 (Comparative Example 4) sequence. Their efficacy was superior to Shingrix®, YK-VZV-007 (Comparative Example 4), YK-VZV-004 (Comparative Example 1), YK-VZV-006 (Comparative Example 2), and YK-VZV-045 (Comparative Example 3). 3. The results of measuring the proportion of CD4+ T and CD8+ T cells secreting IFN-γ and IL-2 in the spleen of mice showed that... ① Based on the percentage of CD4+ T cells, the following 9 sequences were selected: YK-VZV-010, YK-VZV-013, YK-VZV-011, YK-VZV-020, YK-VZV-012, YK-VZV-018, YK-VZV-028, YK-VZV-038, and YK-VZV-031. The combined percentage of IFN-γ+ CD4+ T cells and IL-2+ CD4+ T cells was more than twice that of the Shingrix® positive control, reaching up to seven times; and approximately 1.8 to 5.3 times that of YK-VZV-007 (comparative example 4). The proportion of IFN-γ+ CD4+ T cells reached 1.00~2.00%, which is more than 3 times that of the Shingrix® positive control vaccine, reaching a maximum of 6.7 times; and about 2.2~4.4 times that of YK-VZV-007 (comparative example 4). The percentage of IL-2+ CD4+ T cells both exceeded 1%, and was more than 3.7 times that of the Shingrix® positive control vaccine and more than 2.2 times that of YK-VZV-007; ②Furthermore, based on the percentage of CD8+ T cells, five sequences were identified: YK-VZV-010, YK-VZV-013, YK-VZV-020, YK-VZV-018, and YK-VZV-011. The combined percentage of IFN-γ+ CD8+ T cells and IL-2+ CD8+ T cells was 4 to 7 times higher than that of the Shingrix® vaccine, and approximately 3 to 5 times higher than that of YK-VZV-007 (comparative example 4). The proportion of IFN-γ+ CD8+ T cells was optimal, all above 5.0%, which is 4.5 to 7.0 times that of the Shingrix® positive control vaccine and about 2.5 to 4.5 times that of YK-VZV-007; The proportion of IL-2+ CD8+ T cells was optimal, reaching 0.3-0.5%, which is more than 2.5-4.0 times that of the Shingrix® positive control vaccine and about 1.5-3.0 times that of YK-VZV-007; And all of them were significantly higher than the comparative examples (YK-VZV-004, YK-VZV-006, YK-VZV-045, YK-VZV-007). 4. To verify the above results, based on the test results on day 42, the titer of VZV-binding-gE antibody IgG in the serum of immunized mice on day 56 was further measured and verified. The results showed that on day 56 after mice were immunized with YK-VZV-009, YK-VZV-010, YK-VZV-011, YK-VZV-013, YK-VZV-020, YK-VZV-014, YK-VZV-012, YK-VZV-018, YK-VZV-021, YK-VZV-024, YK-VZV-028, YK-VZV-030, YK-VZV-031, and YK-VZV-038 vaccines, the gE-specific antibody IgG titers of the above mRNA vaccines were all superior to those of the Shingrix® positive control, and were approximately 1.8 to 5.0 times higher than those of the Shingrix® vaccine. Among them, the antibody GMT of YK-VZV-011, YK-VZV-013, YK-VZV-020, YK-VZV-018, and YK-VZV-010 reached over 650×10⁴, which is more than 4.0 to 5.0 times that of the Shingrix® vaccine and more than twice that of YK-VZV-007 (Comparative Example 4). Furthermore, all of them were significantly superior to YK-VZV-004 (Comparative Example 1) and YK-VZV-045 (Comparative Example 3). 5. Five optimal antigen sequences (YK-VZV-010, YK-VZV-013, YK-VZV-011, YK-VZV-020, and YK-VZV-018) were selected based on the combined results of IgG and multi-parameter flow cytometry. These sequences were further validated using the ELISpot method, and the results are as follows: ① The amount of IFN-γ secreted by T cells stimulated by the mRNA vaccine was above 500 SFU, with the highest reaching nearly 600 SFU, which is about 16 to 19 times that of the Shingrix® positive control and 2.5 to 3.0 times that of control 4 (YK-VZV-007); and significantly better than the cytokines secreted by the mRNA vaccines corresponding to control 1 (YK-VZV-004), control 2 (YK-VZV-006) or control 3 (YK-VZV-045). Among them, the mRNA vaccine prepared with the YK-VZV-010 sequence reached a maximum of 598.8 SFU, which is 18.7 times that of the Shingrix® positive control and nearly 3 times that of the YK-VZV-007 control. The IFN-γ secretion levels from high to low were YK-VZV-010, YK-VZV-011, YK-VZV-018, YK-VZV-020, and YK-VZV-013, with no significant differences between groups, and all groups showed good and significant immune effects. ② The amount of IL-2 secreted by T cells stimulated by the mRNA vaccine was above 400-600 SFU, which was 10-16 times that of the Shingrix® positive control and 2.0-3.0 times that of the YK-VZV-007 control; it was also significantly better than the cytokines secreted by the mRNA vaccines corresponding to Comparative Example 1 (YK-VZV-004), Comparative Example 2 (YK-VZV-006), or Comparative Example 3 (YK-VZV-045). Among them, the mRNA vaccine prepared with the YK-VZV-010 sequence reached a maximum of 614.5 SFU, which is 16.0 times that of the Shingrix® positive control and more than 3 times that of the YK-VZV-007 control. The IL-2 secretion levels from high to low were YK-VZV-010, YK-VZV-011, YK-VZV-018, YK-VZV-013, and YK-VZV-020, with no significant differences between groups, and all groups showed good and significant immune effects. 6. In addition, the antigen localization results of the above 5 sequences show that they are localized in the Golgi apparatus, cell membrane, or cytoplasm. Simple Explanation of the Diagram

[0049] The present invention will be further illustrated below through embodiments. It should be understood that the embodiments of the present invention are merely provided for illustrative purposes and are not intended to limit the present invention. Simple improvements to the present invention based on the technical solutions of the present invention are all within the protection scope of the present invention.
[0050] In this document, the term "selected from" means any combination of one, two, three or more of the listed objects or elements.
[0051] It should be understood that the term "a compound" as used herein may include the compound, its N-oxide, its solvate, its pharmaceutically acceptable salt, its stereoisomer, and mixtures thereof.
[0052] Antigen Sequence Design: An antigen is a protein capable of inducing an immune response (e.g., causing the immune system to produce antibodies against the antigen). In this document, the term "antigen" is used to encompass both immunogenic proteins and immunogenic fragments (that induce or are capable of inducing) an immune response to varicella-zoster virus (e.g., VZV), unless otherwise stated. It should be understood that the term "protein" encompasses peptides, and the term "antigen" encompasses antigen fragments. Table 1 provides exemplary sequences of VZV antigens of the compositions of this disclosure and RNA encoding said VZV antigens.
[0053] Nucleic acid: Nucleic acid comprises polymers of nucleotides (nucleotide monomers). The compositions disclosed herein comprise RNA having an open reading frame (ORF) encoding a VZV antigen. In some embodiments, the RNA is messenger RNA (mRNA). In some embodiments, the RNA (e.g., mRNA) further comprises a 5′ UTR, a 3′ UTR, a poly(A) tail, and / or a 5′ cap analogue.
[0054] Messenger RNA (mRNA): any RNA that encodes (at least one) protein (a naturally occurring, non-natural, or modified amino acid polymer) and can be translated in vitro, in vivo, in situ, or ex vivo to produce a protein-encoding RNA. Those skilled in the art will understand that, unless otherwise stated, the nucleic acid sequences described herein may be listed as "T" in a representative DNA sequence, but where said sequence represents RNA (e.g., mRNA), "T" will replace "U". Therefore, any DNA disclosed and identified herein by a specific sequence identification number also discloses a corresponding RNA (e.g., mRNA) sequence complementary to the DNA, wherein each "T" in the DNA sequence is replaced by "U".
[0055] An open reading frame (ORF) is a continuous sequence of DNA or RNA that begins with a start codon (e.g., methionine (ATG)) and ends with a stop codon (e.g., TAA, TAG, or TGA, or UAA, UAG). ORFs typically encode proteins. It should be understood that the sequences disclosed herein may also contain additional elements, such as 5′ and 3′ UTRs.
[0056] Variant RNA: An antigenic variant or other polypeptide variant is a molecule whose amino acid sequence differs from the wild-type, native, or reference sequence. Compared to the native or reference sequence, the antigen / polypeptide variant may have substitutions, deletions, and / or insertions at certain positions within the amino acid sequence. Typically, the variant shares at least 50% identity with the wild-type, native, or reference sequence. In some embodiments, the variant shares at least 80% or at least 90% identity with the wild-type, native, or reference sequence.
[0057] In some embodiments, the composition comprises RNA or RNA ORF containing the nucleotide sequence of any of the sequences provided herein (see, for example, sequence listings and Table 1), or containing at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% of the nucleotide sequence of any of the sequences provided herein.
[0058] The term "identity" refers to the relationship between sequences of two or more polypeptides (e.g., antigens) or polynucleotides (nucleic acids), as determined by sequence comparison. Identity also refers to the degree of sequence relevance between or among sequences, as determined by the number of matches between two or more amino acid residues or nucleic acid residue strings. Identity measures the percentage of identity matches between the smaller of two or more sequences with vacancy alignments (if any), processed by a specific mathematical model or computer program (e.g., an "algorithm"). The identity of related antigens or nucleic acids can be readily calculated using known methods. "Identity percentage (%)" when applied to polypeptide or polynucleotide sequences is defined as the percentage of residues in the candidate amino acid or nucleic acid sequence that are identical to residues in the amino acid or nucleic acid sequence of a second sequence after sequence alignment and the introduction of vacancy (if necessary) to achieve the maximum identity percentage. Methods and computer programs used for alignment are well known in the art. It should be understood that identity depends on the calculation of the identity percentage, but the value of identity may differ due to vacancy and penalty introduced in the calculation. Typically, a variant of a specific polynucleotide or polypeptide (e.g., an antigen) has at least 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, but less than 100% sequence identity with the specific reference polynucleotide or polypeptide, as determined by sequence alignment procedures and parameters known to those of ordinary skill in the art described herein and to which this invention pertains. Such tools for alignment include those in BLAST suites (Stephen F. Altsch et al. (1997), "Gapped BLAST and PSI-BLAST: a new generation of protein database search programs", Nucleic Acids Res. 25:3389-3402).
[0059] Therefore, polynucleotides encoding peptides or polypeptides containing substitutions, insertions, and / or additions or deletions relative to a reference sequence, particularly the antigen sequence disclosed herein, are all included within the scope of this disclosure. Amino residues located at the carboxyl and amino terminal regions of the amino acid sequence of a peptide or protein may optionally be deleted to provide a truncated sequence. Depending on the structure and purpose of the sequence, the gE protein possesses several important domains related to its primary function (Figure 1). The gE protein possesses several important domains related to its primary function (Figure 3). (1) The TM transmembrane domain, composed of amino acids at positions 539-559; (2) A568YRV571: mediates the transport of gE between the endoplasmic reticulum (ER), the trans-Golgi network (TGN), and the endosome; (3) Y582AGL585: mediates the transport of gE between the endoplasmic reticulum (ER), the trans-Golgi network (TGN), and the endosome; (4) S593ES595T596DT598: an important glycosylation site; mediates the transport of gE between the endoplasmic reticulum (ER), the trans-Golgi network (TGN), and the endosome. In some embodiments, important structural sites can be removed and replaced with appropriate residues to alter antigen transport and expression, thereby enhancing the immunogenicity of the antigen. Such sequences can be readily identified by those skilled in the art to which this invention pertains. It should also be understood that some of the sequences provided herein contain sequence tags or terminal peptide sequences (e.g., at the N-terminus or C-terminus) that may be missing prior to, for example, the preparation of RNA (e.g., mRNA) vaccines.
[0060] As will be recognized by those skilled in the art to which this invention pertains, protein fragments, functional protein domains, and homologous proteins are also considered to be within the scope of the target varicella-zoster virus antigen. For example, any protein fragment of a reference protein (meaning a polypeptide sequence that is at least one amino acid residue shorter than the reference antigen sequence but otherwise identical) is provided herein, provided that the fragment is immunogenic and confers a protective immune response against varicella-zoster virus. In addition to variants that are identical to but truncated from the reference protein, in some embodiments, as shown in any sequence provided or referenced herein, the antigen includes mutations at sites 2, 3, 4, 5, 6, 7, 8, 9, 10, or more. The length of the antigen / antigenic polypeptide can range from about 4, 6, or 8 amino acids to the full-length protein.
[0061] VZV Antigen Variants: This invention includes variant VZV antigenic peptides. In some embodiments, the variant VZV antigenic peptide is a variant VZV gE peptide. The variant VZV gE peptide is designed to avoid ER / Horgitschlia retention of the peptide, resulting in increased surface expression of the antigen. In some embodiments, the variant gE peptide is truncated to remove the ER-retained portion or the cytoplasmic tail portion of the peptide. In some embodiments, the variant VZV gE peptide is mutated to reduce the localization of the VZV peptide to ER / Horgitschlia / TGN. This modification inhibits ER capture and thus accelerates transport to the cell membrane. Therefore, in some embodiments, the VZV glycoprotein is a variant gE peptide. VZV gE has a target sequence for TGN at its C-terminus and is transported from ER to TGN in infected and gE-transfected cells. Most gE in TGN appears to be retrieved from the plasma membrane via endocytosis and transferred from the endosome to the TGN, then recycled back to the plasma membrane. gE accumulates in the TGN along with other VZV proteins (e.g., envelope proteins) associated with the production of intact enveloped VZV viral particles. Therefore, mutations that reduce TGN localization and endocytosis facilitate the transport of gE to the cell membrane. The variant VZV gE polypeptide can be any truncated polypeptide lacking an anchor domain (ER-retained domain). For example, the variant VZV gE polypeptide can be a truncated VZV gE polypeptide containing at least amino acids 1 to 124, such as truncated VZV gE polypeptides containing amino acids 1 to 124, 1 to 140, 1 to 160, 1 to 200, 1 to 250, 1 to 300, 1 to 350, 1 to 360, 1 to 400, 1 to 450, 1 to 500, 1 to 511, 1 to 550, and 1 to 561, as well as polypeptide fragments having fragment sizes within the referenced size range. In some embodiments, the variant VZV gE polypeptide is a truncated polypeptide lacking a carboxyl-terminal tail domain. Therefore, in some embodiments, the truncated VZV gE polypeptide comprises amino acids 1 to 573 of SEQ ID NO: 59. In some embodiments, the variant VZV gE polypeptide has at least one mutation in one or more motifs associated with ER retention, wherein the mutation in one or more motifs results in reduced retention of the VZV gE polypeptide in the ER and / or Gauzynes. In some embodiments, the variant VZV gE polypeptide has at least one mutation in one or more phosphorylated acidic motifs. For example, the variant VZV gE polypeptide may be a full-length VZV gE polypeptide having a Y582G mutation, a Y569K mutation, or both a Y582G mutation and a Y569K mutation. Alternatively, the variant VZV gE polypeptide may be an antigenic fragment comprising, for example, amino acids 1 to 573 of VZV gE and having a Y569K mutation. Alternatively, the variant VZV gE polypeptide may be an antigenic fragment having a mutation in an acidic phosphorylated motif (such as an SSTT motif).For example, the variant VZV gE polypeptide can be an antigenic fragment having the AEAADA sequence (SEQ ID NO: 183).
[0062] Naturally occurring eukaryotic mRNA molecules, in addition to other structural features such as a 5′-cap structure or a 3′-poly(A) tail, may contain stabilizing elements, including but not limited to untranslated regions (UTRs) at their 5′ end (5′UTR) and / or at their 3′ end (3′UTR). Both the 5′UTR and 3′UTR are typically elements transcribed from genomic DNA and are pre-mature mRNAs. Characteristic structural features of mature mRNA (e.g., a 5′-cap and a 3′-poly(A) tail) are usually added to the transcribed (pre-mature) mRNA during mRNA processing.
[0063] In some embodiments, the composition comprises an RNA polynucleotide having an open reading frame encoding at least one antigenic polypeptide having at least one modification, at least one 5′ terminal cap, and formulated within lipid nanoparticles. The 5′-capping of the polynucleotide can be performed simultaneously during in vitro transcription using a chemical RNA cap analog, according to the manufacturer's protocol, to produce a 5′-guanosine cap structure. In some cases, the 5′-capping of the modified RNA can also be performed post-transcriptionally using a vaccinia virus capping enzyme to produce a "cap" structure. Cap 1 can be produced using a vaccinia virus capping enzyme and a 2′-O methyltransferase to produce: m7G(5′)ppp(5′)G-2′-O-methyl. Cap 2 can be produced from Cap 1 by 2′-O-methylation of the 5′-last nucleotide using a 2′-O methyltransferase. Cap 3 can be produced from Cap 2 by 2′-O-methylation of the 5′-last nucleotide using a 2′-O methyltransferase. The enzymes can be derived from recombinant sources. The 3′-poly(A) tail is typically an adenine nucleotide appended to the 3′ end of the transcribed mRNA. In some cases, it can contain up to about 400 adenine nucleotides. In some embodiments, the length of the 3′-poly(A) tail may be an essential factor for the stability of the individual mRNA.
[0064] Chemical Modification: In some embodiments, the compositions of this disclosure comprise RNA having an open reading frame encoding a VZV antigen, wherein the nucleic acid comprises nucleotides and / or nucleosides that may be standard (unmodified) or modified as known in the art. In some embodiments, the nucleotides and nucleosides of this disclosure comprise modified nucleotides or nucleosides. Such modified nucleotides and nucleosides may be naturally occurring modified nucleotides and nucleosides or non-naturally occurring modified nucleotides and nucleosides. Such modifications may include those modifications at the sugar, backbone, or nucleobase moieties of the nucleotides and / or nucleosides as recognized in the art.
[0065] In some embodiments, the naturally occurring modified nucleotides or nucleosides disclosed herein are nucleotides or nucleosides generally known or recognized in the art. Non-limiting examples of such naturally occurring modified nucleotides and nucleosides can be found, in particular, in the widely recognized MODOMICS database.
[0066] In some embodiments, the non-naturally occurring modified nucleotides or nucleosides of this disclosure are nucleotides or nucleosides generally known or recognized in the art. Non-limiting examples of such non-naturally occurring modified nucleotides and nucleosides can be found in particular in the published U.S. applications PCT / US2012 / 058519; PCT / US2013 / 075177; PCT / US2014 / 058897; PCT / US2014 / 058891; PCT / US2014 / 070413; PCT / US2015 / 36773; PCT / US2015 / 36759; PCT / US2015 / 36771; or PCT / IB2017 / 051367, all of which are incorporated herein by reference.
[0067] Therefore, the nucleic acids (e.g., DNA nucleic acids and RNA nucleic acids, such as mRNA nucleic acids) disclosed herein may comprise standard nucleotides and nucleosides, naturally occurring nucleotides and nucleosides, non-naturally occurring nucleotides and nucleosides, or any combination thereof.
[0068] In some embodiments, the nucleic acids of this disclosure (e.g., DNA nucleic acids and RNA nucleic acids, such as mRNA nucleic acids) comprise multiple (more than one) different types of standard and / or modified nucleotides and nucleosides. In some embodiments, specific regions of the nucleic acid contain one, two, or more (optionally different) types of standard and / or modified nucleotides and nucleosides.
[0069] In some implementations, modified RNA nucleic acids (e.g., modified mRNA nucleic acids) introduced into cells or organisms exhibit reduced degradation in cells or organisms, relative to unmodified nucleic acids containing standard nucleotides and nucleosides.
[0070] In some implementations, modified RNA nucleic acids (e.g., modified mRNA nucleic acids) introduced into cells or organisms may exhibit reduced immunogenicity in cells or organisms, relative to unmodified nucleic acids containing standard nucleotides and nucleosides.
[0071] In some implementations, nucleic acids (e.g., RNA nucleic acids, such as mRNA nucleic acids) contain non-naturally modified nucleotides introduced during or after nucleic acid synthesis to achieve a desired function or property. Modifications can be present at internucleotide links, purine or pyrimidine bases, or sugars. Modifications can be introduced chemically or using polymerases at the ends of the chain or anywhere else in the chain. Any region of the nucleic acid can be chemically modified.
[0072] This disclosure provides modified nucleosides and nucleotides of nucleic acids (e.g., RNA nucleic acids, such as mRNA nucleic acids). "Nucleoside" refers to a compound containing a sugar molecule (e.g., pentose or ribose) or a derivative thereof combined with an organic base (e.g., purine or pyrimidine) or a derivative thereof (also referred to herein as "nucleobase"). "Nucleotide" refers to a nucleoside comprising a phosphate group. Modified nucleotides can be synthesized by any useful method, such as chemical, enzymatic, or recombinant methods, to comprise one or more modified or non-natural nucleosides. Nucleic acids may contain one or more regions of linked nucleosides. Such regions may have variable backbone bonds. The bonds may be standard phosphodiester bonds, in which case the nucleic acid will contain the nucleotide region.
[0073] Modified nucleotide base pairings encompass not only standard adenosine-thymine, adenosine-uracil, or guanosine-cytosine base pairs, but also base pairs formed between nucleotides and / or modified nucleotides containing non-standard or modified bases, wherein the arrangement of hydrogen bond donors and acceptors allows hydrogen bonding between non-standard bases and standard bases or between two complementary non-standard base structures, such as in nucleic acids having at least one chemical modification. An example of such non-standard base pairings is the base pairing between modified nucleotides inosine and adenine, cytosine, or uracil. Any combination of base / sugar or linker may be incorporated into the nucleic acids of this disclosure.
[0074] In some embodiments, the modified nucleotides in the nucleic acid (e.g., RNA nucleic acid, such as mRNA nucleic acid) comprise 1-methyl-pseudouridine (m1ψ), 1-ethyl-pseudouridine (e1ψ), 5-methoxy-uridine (mo5U), 5-methyl-cytidine (m5C), and / or pseudouridine (ψ). In some embodiments, the modified nucleotides in the nucleic acid (e.g., RNA nucleic acid, such as mRNA nucleic acid) comprise 5-methoxymethyluridine, 5-methylthiouridine, 1-methoxymethylpseudouridine, 5-methylcytidine, and / or 5-methoxycytidine. In some embodiments, the polynucleotide comprises at least two (e.g., 2, 3, 4, or more) combinations of any of the modified nucleotides mentioned above, including but not limited to chemical modifications.
[0075] In some embodiments, the mRNA disclosed herein contains 1-methyl-pseudouridine (m1ψ) substitution at one or all uridine positions of the nucleic acid.
[0076] In some embodiments, the mRNA disclosed herein comprises 1-methyl-pseudouridine (m1ψ) substitution at one or more or all uridine positions in the nucleic acid and 5-methylcytidine substitution at one or more or all cytidine positions in the nucleic acid.
[0077] In some embodiments, the mRNA disclosed herein contains pseudouridine (ψ) substitutions at one or all uridine sites in the nucleic acid.
[0078] In some implementations, for a specific modification, the mRNA is uniformly modified (e.g., completely modified, modified throughout the entire sequence). For example, nucleic acids can be uniformly modified with 1-methyl-pseudouridine, meaning that all uridine residues in the mRNA sequence are replaced with 1-methyl-pseudouridine. Similarly, nucleic acids can be uniformly modified for any type of nucleoside residue present in the sequence by substitution with modified residues (e.g., those explained above).
[0079] The nucleic acid may contain from about 1% to about 100% modified nucleotides (relative to the total nucleotide content, or relative to one or more types of nucleotides, i.e., any or more of A, G, U, or C) or any intercalary percentage (e.g., 1% to 20%, 1% to 25%, 1% to 50%, 1% to 60%, 1% to 70%, 1% to 80%, 1% to 90%, 1% to 95%, 10% to 20%, 10% to 25%, 10% to 50%, 10% to 60%, 10% to 70%, 10% to 80%, 10% to 90%, 10% to 95%, 10%). (up to 100%, 20% to 25%, 20% to 50%, 20% to 60%, 20% to 70%, 20% to 80%, 20% to 90%, 20% to 95%, 20% to 100%, 50% to 60%, 50% to 70%, 50% to 80%, 50% to 90%, 50% to 95%, 50% to 100%, 70% to 80%, 70% to 90%, 70% to 95%, 70% to 100%, 80% to 90%, 80% to 95%, 80% to 100%, 90% to 95%, 90% to 100%, and 95% to 100%). It should be understood that the presence of unmodified A, G, U, or C accounts for any remaining percentage.
[0080] The mRNA may contain at least 1% and at most 100% of modified nucleotides or any intercalary percentage, such as at least 5%, at least 10%, at least 25%, at least 50%, at least 80%, or at least 90% of modified nucleotides. For example, the nucleic acid may contain modified pyrimidines, such as modified uracil or cytosine. In some embodiments, at least 5%, at least 10%, at least 25%, at least 50%, at least 80%, at least 90%, or 100% of the uracil in the nucleic acid is replaced by modified uracil (e.g., 5-substituted uracil). The modified uracil may be replaced by a compound having a single unique structure or by multiple compounds having different structures (e.g., 2, 3, 4, or more unique structures). In some embodiments, at least 5%, at least 10%, at least 25%, at least 50%, at least 80%, at least 90%, or 100% of the cytosine in the nucleic acid is replaced by modified cytosine (e.g., 5-substituted cytosine). The modified cytosine may be replaced by a compound having a single unique structure, or by multiple compounds having different structures (e.g., 2, 3, 4, or more unique structures).
[0081] Untranslated Region (UTR): The mRNA disclosed herein may contain one or more regions or portions that act as or are used as untranslated regions. When the mRNA is designed to encode at least one target antigen, the nucleic acid may contain one or more of these untranslated regions (UTRs). The wild-type untranslated region of the nucleic acid is transcribed but not translated. In mRNA, the 5′UTR begins at the transcription start site and continues to the start codon, but does not include the start codon; while the 3′UTR begins immediately after the stop codon and continues to the transcription termination signal. Increasing evidence suggests the regulatory role of UTRs in the stability and translation of nucleic acid molecules. Regulatory features of UTRs may be incorporated into the polynucleotides of this disclosure to particularly enhance molecular stability. Specific features may also be incorporated to ensure controlled downregulation of the transcript in cases where the transcript is misdirected to an undesirable organ site. Various 5′UTR and 3′UTR sequences are known and available in the art.
[0082] In some embodiments of this disclosure, the 5′UTR is a heterologous UTR, i.e., a UTR found in nature that is associated with a different ORF. In another embodiment, the 5′UTR is a synthetic UTR, i.e., one that does not occur in nature. Synthetic UTRs include UTRs that have been mutated to improve their properties, such as UTRs that increase gene expression, as well as completely synthetic UTRs. Exemplary 5′UTRs include Xenopus xenograft or human α-globulin or β-globulin (8278063; 9012219), human cytochrome b-245a polypeptide and hydroxysteroid (17b) dehydrogenase, and tobacco etch virus (US8278063, 9012219).
[0083] In some embodiments, the 5′UTR of this disclosure contains a sequence selected from SEQ ID NO:173~174.
[0084] In some preferred embodiments, the 5′UTR of this disclosure comprises a sequence selected from SEQ ID NO:174.
[0085] The 3′UTR is the region of mRNA directly downstream (3′) of the stop codon (the codon that signals the termination of translation in mRNA transcripts). The 3′UTR does not encode proteins (it is non-coding). Natural or wild-type 3′UTRs are known to contain segments containing adenosine (A) and uridine (U). These AU-rich imprints are particularly prevalent in genes with high turnover rates.
[0086] The introduction, removal, or modification of AU-rich elements (AREs) in the 3′UTR can be used to modulate the stability of nucleic acids (e.g., RNA) disclosed herein. When engineering a specific nucleic acid, one or more copies of AREs can be introduced to make the nucleic acid of this disclosure less stable, thereby reducing translation and decreasing the production of the resulting protein. Similarly, AREs can be identified and removed or mutated to increase intracellular stability, thereby increasing the translation and production of the resulting protein.
[0087] 3′UTRs can be heterologous or synthetic. Regarding 3′UTRs, globulin UTRs (including Xenopus β-globulin UTRs and human β-globulin UTRs) are known in the art (8278063, 9012219, US20110086907). By selectively colonizing two consecutive human β-globulin 3′UTRs end-to-end, modified β-globulin-encoding nucleic acids (e.g., mRNAs) with enhanced stability in several cell types have been developed, and these are well known in the art (US2012 / 0195936, WO2014 / 071963).
[0088] In some embodiments, the 3′UTR of this disclosure contains a sequence selected from SEQ ID NO:175.
[0089] Those skilled in the art will understand that heterologous or synthetic 5′UTRs can be used with any desired 3′UTR sequence. For example, a heterologous 5′UTR can be used with a synthetic 3′UTR or a heterologous 3′UTR.
[0090] It should be understood that any UTR from any gene can be incorporated into a region of nucleic acid. Furthermore, multiple wild-type UTRs of any known gene can be utilized. Artificial UTRs that provide variants that are not wild-type regions are also within the scope of this disclosure. These UTRs, or portions thereof, can be positioned in the same orientation as in the transcript from which they are selected, or can be altered in orientation or position. Thus, 5′ or 3′ UTRs can be inverted, shortened, lengthened, or prepared together with one or more other 5′ or 3′ UTRs. As used herein, the term "altered" when referring to a UTR sequence means that the UTR has been altered in some way relative to a reference sequence. For example, a 3′ or 5′ UTR can be altered relative to a wild-type or native UTR by changes in orientation or position as taught above, or by changes including additional nucleotides, deletions of nucleotides, exchanges of nucleotides, or transpositions. Any of these alterations that produce an "altered" UTR (whether 3′ or 5′) comprises a variant UTR.
[0091] RNA in vitro transcription: cDNA encoding the polynucleotides described herein can be transcribed using an in vitro transcription (IVT) system. In some embodiments, the RNA transcript is produced in an in vitro transcription reaction using a non-amplified linearized DNA template to produce RNA transcript. In some embodiments, the template DNA is isolated DNA. In some embodiments, the template DNA is cDNA. In some embodiments, the cDNA is formed by circular plasmid DNA digestion. In some embodiments, cells, such as bacterial cells, such as *E. coli*, or DH-1 cells, are transfected with the plasmid DNA template. In some embodiments, the transfected cells are cultured to replicate the plasmid DNA, and then the plasmid DNA is isolated and purified. In some embodiments, the DNA template includes an RNA polymerase promoter, such as the T7 promoter located at the 5′ of the target gene and operatively linked thereto.
[0092] In some implementations, the in vitro transcription template encodes a 5′ untranslated (UTR) region containing an open reading frame, and also encodes a 3′ UTR and a poly(A) tail. The specific nucleic acid sequence composition and length of the in vitro transcription template will depend on the mRNA encoded by the template.
[0093] The "5′ untranslated region" (UTR) refers to the region of mRNA that does not encode a polypeptide, located directly upstream (i.e., 5′) of the start codon (i.e., the first codon of the mRNA transcript translated by ribosomes). When an RNA transcript is produced, the 5′ UTR may contain a promoter sequence. Such promoter sequences are known in the art. It should be understood that such promoter sequences will not be present in the vaccines disclosed herein.
[0094] The "3′ untranslated region" (UTR) refers to the region of mRNA that does not encode a polypeptide, located directly downstream (i.e., 3′) of the stop codon (i.e., the codon of the mRNA transcript that sends the translation termination signal).
[0095] An "open reading frame" is a continuous segment of DNA that begins with a start codon (e.g., methionine (ATG)) and ends with a stop codon (e.g., TAA, TAG, or TGA) and encodes a polypeptide.
[0096] A poly(A) tail is a region of mRNA located downstream, for example, directly downstream (i.e., 3′), of a 3′ UTR containing multiple consecutive adenosine monophosphates (ATPs). The poly(A) tail can contain 10 to 300 ATPs. For example, a poly(A) tail can contain 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, or 300 ATPs. In some embodiments, the poly(A) tail contains 50 to 250 ATPs. In relevant biological environments (e.g., in cells, in vivo), the poly(A) tail serves to protect mRNA from enzymatic degradation, for example, in the cytoplasm, and to facilitate transcription termination, and / or mRNA export from the nucleus and translation.
[0097] In some implementations, the nucleic acid comprises 200 to 3,000 nucleotides. For example, the nucleic acid may comprise 200 to 500, 200 to 1000, 200 to 1500, 200 to 3000, 500 to 1000, 500 to 1500, 500 to 2000, 500 to 3000, 1000 to 1500, 1000 to 2000, 1000 to 3000, 1500 to 3000, or 2000 to 3000 nucleotides.
[0098] In vitro transcription systems typically contain transcription buffer, nucleotide triphosphates (NTPs), RNase inhibitors, inorganic pyrophosphates, and polymerases.
[0099] The NTP may be manufactured in-house, selected from a supplier, or synthesized as described herein. The NTP may be selected from, but is not limited to, those NTPs described herein, including natural and non-natural (modified) NTPs.
[0100] Any number of RNA polymerases or variants may be used in the methods of this disclosure. The polymerase may be selected from, but is not limited to, bacteriophage RNA polymerases, such as T7 RNA polymerase, T3 RNA polymerase, SP6 RNA polymerase, and / or mutant polymerases, such as, but not limited to, polymerases capable of incorporating modified nucleic acids and / or modified nucleotides (including chemically modified nucleic acids and / or nucleotides). Some embodiments exclude the use of DNases.
[0101] In some implementations, RNA transcripts can be capped via enzymatic capping or co-transcriptional capping. In some implementations, the RNA contains a 5′ end cap, such as 7mG(5′)ppp(5′)NlmpNp.
[0102] Purification of mRNA: The purification of nucleic acids described herein may include, but is not limited to, nucleic acid purification, quality assurance, and quality control. Purification may be carried out by methods known in the art, such as, but not limited to, lithium chloride precipitation, beads (Beckman & Co., Microter Genomics, Danvers, MA), poly-T beads, LNATM oligo-T capture probes (Vedbaek, Denmark), or HPLC-based purification methods, such as, but not limited to, strong anion exchange HPLC, weak anion exchange HPLC, reversed-phase HPLC (RP-HPLC), and hydrophobic interaction HPLC (HIC-HPLC). The term "purified" when used with respect to nucleic acids, such as "purified nucleic acid," refers to nucleic acids isolated from at least one contaminant. A "contaminant" is any substance that makes another substance unsuitable, impure, or inferior. Thus, purified nucleic acids (e.g., DNA and RNA) exist in a form or environment different from their natural occurrence or in a form or environment different from their existence prior to the treatment or purification method.
[0103] Quality assurance and / or quality control checks may be performed using methods such as, but not limited to, gel electrophoresis, UV absorbance, or analytical HPLC.
[0104] Quantification: In some embodiments, nucleic acids can be quantified using methods such as, but not limited to, ultraviolet-visible spectroscopy (UV / Vis). A non-limiting example of a UV / Vis spectrometer is a spectrometer (ThermoFisher, Waltham, MA). The quantified nucleic acids can be analyzed to determine whether the nucleic acids are of appropriate size and to check that the nucleic acids have not been degraded. Degradation of nucleic acids can be checked by methods such as, but not limited to, agarose gel electrophoresis; HPLC-based purification methods such as, but not limited to, strong anion exchange HPLC, weak anion exchange HPLC, reversed-phase HPLC (RP-HPLC), and hydrophobic interaction HPLC (HIC-HPLC); liquid chromatography-mass spectrometry (LCMS), capillary electrophoresis (CE), and capillary gel electrophoresis (CGE).
[0105] Lipid nanoparticles (LNPs): In some embodiments, the RNA (e.g., mRNA) of this disclosure is formulated in lipid nanoparticles (LNPs). Lipid nanoparticles typically contain ionizable cationic lipids, non-cationic lipids, sterols and PEG lipid components, and the target nucleic acid cargo.

LNPs are currently one of the mainstream delivery carriers.
[0107] In this paper, the term "neutral lipid" refers to lipids that are uncharged at a selected pH or exist in a zwitterionic form and play an auxiliary role. These neutral lipids may modulate the fluidity of nanoparticles to form lipid bilayers and improve efficiency by promoting lipid phase transitions, and may also affect the specificity of target organs.
[0108] In this document, "structural lipids" refers to lipids that enhance the stability of nanoparticles by filling the gaps between lipids. Structural lipids may be selected from, but are not limited to, the group consisting of: cholesterol, non-steroidal, sitosterol, ergosterol, campesterol, stigmasterol, brassicasterol, tomatine, ursolic acid, α-tocopherol, corticosteroids, and mixtures thereof.

[0142] Pharmaceutical formulations: This document provides compositions (e.g., pharmaceutical compositions), methods, kits, and reagents for the prevention or treatment of varicella-zoster virus, such as in humans and other mammals. The compositions provided herein can be used as therapeutic or preventative agents. They can be used in pharmaceuticals for the prevention and / or treatment of shingles.
[0143] In some implementations, a shingles vaccine containing RNA as described herein may be administered to a subject (e.g., a mammalian subject, such as a human subject), and the RNA polynucleotide may be translated in vivo to produce an antigenic polypeptide (antigen).
[0144] The “effective amount” of a composition (e.g., containing RNA) is based at least in part on the target tissue, target cell type, administration method, physical characteristics of the RNA (e.g., length, nucleotide composition, and / or degree of nucleoside modification), other components of the vaccine, and other determinants such as the subject’s age, weight, height, sex, and general health status. Typically, an effective amount of the composition provides an induced or enhanced immune response that varies with antigen production in the subject’s cells. In some embodiments, an effective amount of a composition containing an RNA polynucleotide with at least one chemical modification is more effective than a composition containing a corresponding unmodified polynucleotide encoding the same antigen or peptide antigen. Increased antigen production can be demonstrated by increased cell transfection (the percentage of cells transfected with an RNA vaccine), increased protein translation and / or expression from the polynucleotide, reduced nucleic acid degradation (e.g., as by an increased duration of protein translation from the modified polynucleotide), or alterations in the host cell’s antigen-specific immune response.
[0145] The term "pharmaceutical composition" refers to a combination of an active agent and an inert or active carrier, making the composition particularly suitable for in vivo or in vitro diagnostic or therapeutic use. A "pharmaceuticalally acceptable carrier" is one that does not cause undesirable physiological effects upon or during administration to a subject. The carrier in a pharmaceutical composition must also be "acceptable" in the sense that it is compatible with and stabilizes the active ingredient. One or more solubilizers may be used as pharmaceutical carriers for delivering the active agent.
[0146] In some embodiments, the compositions according to this disclosure (comprising polynucleotides and polypeptides encoded therein) can be used to treat or prevent herpes zoster. The compositions can be administered prophylactically or therapeutically to healthy individuals as part of an active immunization program, or early in the course of infection during the incubation period or during active infection following symptom onset. In some embodiments, the amount of RNA provided to cells, tissues, or subjects can be an amount effective for immunoprophylaxis.
[0147] In some embodiments, the composition may be administered via intramuscular injection.
[0148] Depending on the prevalence of infection or the extent or level of unmet medical needs, the composition can be used in a variety of settings. As a non-limiting example, RNA vaccines can be used to treat and / or prevent a variety of infectious diseases. RNA vaccines have superior properties because they produce much higher antibody titers, better neutralizing immunity, produce more durable immune responses, and / or generate responses earlier than commercially available vaccines.
[0149] This document provides pharmaceutical compositions comprising RNA and / or complexes, optionally combined with one or more pharmaceutically acceptable excipients. In addition to conventional excipients (e.g., any and all solvents, dispersion media, diluents or other liquid media, dispersing or suspending agents, surfactants, isotonic agents, thickeners or emulsifiers, preservatives), excipients may also include (but are not limited to) lipids, liposomes, lipid nanoparticles, polymers, lipid complexes, core-shell nanoparticles, peptides, proteins, RNA-transfected cells (e.g., for transplantation into a subject), hyaluronidase, nanoparticle mimics, and combinations thereof.
[0150] The RNA can be formulated or administered alone, or in combination with one or more other components. For example, the immune composition may contain other components, including but not limited to adjuvants.
[0151] The relative amounts of the active ingredient, pharmaceutically acceptable excipients, and / or any additional ingredients in the pharmaceutical compositions according to this disclosure will vary depending on the identity, body type, and / or condition of the subject being treated and, more particularly, on the route of administration of the composition. For example, the composition may contain between 0.1% and 100%, such as between 0.5% and 50%, between 1% and 30%, between 5% and 80%, and at least 80% (w / w) of the active ingredient.
[0152] In some implementations, one or more excipients are used to formulate RNA to increase mRNA stability, increase cell transfection efficiency and protein translation efficiency, and alter the biodistribution of mRNA to target specific tissues or cell types.
[0153] Administration / Prescription: This document provides immune compositions (e.g., RNA vaccines), methods, kits, and reagents for the prevention of varicella-zoster virus infection in humans and other mammals. The immune compositions can be used as therapeutic or prophylactic agents. In some embodiments, the immune compositions are used to provide prophylactic protection against shingles.
[0154] The object can be any mammal, including non-human primates and human objects.
[0155] In some embodiments, an immune composition (e.g., an mRNA vaccine) is administered in an effective amount to a subject (e.g., a mammalian subject, such as a human subject) to induce an antigen-specific immune response. RNA encoding the VZV gE antigen is expressed and translated in vivo to produce the antigen, which then stimulates the subject's immune response.
[0156] Prophylactic protection against shingles can be achieved after administration of the immunizing composition disclosed herein (e.g., an mRNA vaccine). The immunizing composition may be administered once, twice, three times, four times, or more, but it is possible that a single administration of the vaccine is sufficient (optionally followed by a single booster).
[0157] In this disclosure, methods are provided for inducing an immune response against varicella-zoster virus antigens (or multiple antigens) in a subject. In some embodiments, the method includes administering to the subject an immune composition comprising RNA (e.g., mRNA) having an open reading frame encoding the VZV gE glycoprotein, thereby inducing an immune response in the subject specifically against the varicella-zoster virus antigen, wherein the anti-antigen antibody titer in the subject increases after vaccination relative to the anti-antigen antibody titer in a subject vaccinated with a conventional vaccine (such as GSK's recombinant subunit vaccine). An "anti-antigen antibody" is a serum antibody that specifically binds to an antigen.
[0158] An effective preventive dose is a dose that is clinically acceptable in preventing viral infection. In some embodiments, the effective dose is the dose listed in the vaccine's instructions for use or packaging insert. As used herein, a conventional vaccine refers to a vaccine other than the mRNA vaccine disclosed herein. For example, conventional vaccines include (but are not limited to) live microbial vaccines, inactivated microbial vaccines, subunit vaccines, protein antigen vaccines, DNA vaccines, virus-like particle (VLP) vaccines, etc. In exemplary embodiments, a conventional vaccine is a vaccine that has been approved by a regulatory authority and / or registered with a national drug regulatory agency (such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA)).
[0159] In other aspects of this disclosure, a method for inducing an immune response against varicella-zoster virus in a subject is provided. The method includes administering to the subject an immune composition (e.g., an RNA vaccine) comprising an RNA polynucleotide containing an open reading frame encoding a VZV gE antigen, thereby inducing a varicella-zoster virus-specific immune response in the subject.
[0160] In other embodiments, the immune response is assessed by measuring proteins (antibody titers) in the subject. In still other embodiments, the ability of serum or antibodies from the immunized subject to neutralize viral uptake or reduce varicella-zoster virus conversion of human B lymphocytes is tested. In yet other embodiments, the ability to promote a robust T-cell response is measured using techniques recognized in the art.
[0161] This article also provides a method for inducing an immune response against varicella-zoster virus in a subject by administering RNA having an open reading frame encoding a first antigen, wherein the RNA does not include stabilizing elements and wherein the adjuvant is not co-formulated or co-administered with the vaccine.
[0162] Immunological compositions (e.g., RNA vaccines) can be administered via any route that produces a therapeutically effective outcome. These routes include (but are not limited to) intradermal, intramuscular, or subcutaneous administration. This disclosure provides methods for administering RNA vaccines to subjects in need. The exact amount required will vary depending on the subject's species, age and general condition, disease severity, the specific composition, its administration method, its mode of activity, etc. RNA is typically formulated in dose units for ease of administration and uniformity of dosage. However, it should be understood that the total daily dose of RNA may be determined by the attending physician within reasonable medical judgment. The specific therapeutic, prophylactic, or appropriate imaging dose level for any particular patient will depend on a variety of factors, including the condition being treated and its severity; the activity of the specific compound used; the specific composition used; the patient's age, weight, general health condition, sex, and diet; the timing, route of administration, and the rate of excretion of the specific compound used; the duration of treatment; drugs used in combination with or concurrently with the specific compound used; and similar factors well known in the medical field.
[0163] The effective amount of RNA provided herein can be as low as 5 μg, for example, administered as a single dose or two 2.5 μg doses. In some embodiments, the effective amount is a total dose from 5 μg to 200 μg. For example, the effective amount can be a total dose of 5 μg, 10 μg, 20 μg, 25 μg, 30 μg, 35 μg, 40 μg, 45 μg, 50 μg, 55 μg, 60 μg, 65 μg, 70 μg, 75 μg, 80 μg, 85 μg, 90 μg, 95 μg, 100 μg, 110 μg, 120 μg, 130 μg, 140 μg, 150 μg, 160 μg, 170 μg, 180 μg, 190 μg, or 200 μg. In some embodiments, the effective amount is a total dose from 5 μg to 200 μg. In some embodiments, the effective amount is a total dose of 10 μg. In some embodiments, the effective amount is a total dose of 20 μg. In some embodiments, the effective amount is a total dose of 75 μg. In some embodiments, the effective amount is a total dose of 150 μg. In some embodiments, the effective amount is a total dose of 200 μg.
[0164] Vaccine efficacy Some aspects of this disclosure provide formulations of immune compositions (e.g., RNA vaccines) wherein RNA is formulated in an effective amount to generate an antigen-specific immune response in a subject (e.g., to generate antibodies specific to varicella-zoster virus antigens). "Effective amount" is the dose of RNA that effectively generates an antigen-specific immune response. Methods for inducing an antigen-specific immune response in a subject are also provided herein.
[0165] As used herein, an immune response to the vaccine or LNP of this disclosure is a humoral and / or cellular immune response in a subject to (one or more) varicella-zoster virus proteins present in the vaccine. For the purposes of this disclosure, "humoral" immune responses refer to immune responses mediated by antibody molecules, including, for example, secretory (IgA) or IgG molecules, while "cellular" immune responses are immune responses mediated by T lymphocytes (e.g., CD4+ helper cells and / or CD8+ T cells (e.g., CTLs)) and / or other leukocytes. An important aspect of cellular immunity includes antigen-specific responses induced by cytolytic T cells (CTLs). CTLs are specific for peptide antigens presented and expressed on the cell surface, which are associated with proteins encoded by the major histocompatibility complex (MHC). CTLs help induce and promote the lysis of cells that have been infected with intracellular microbes or by other microbes. Another aspect of cellular immunity includes antigen-specific responses induced by helper T cells. Helper T cells help stimulate function and concentrate the activity of nonspecific effector cells on cells that display peptide antigens associated with MHC molecules on their surfaces. Cellular immune responses also result in the production of cytokines (e.g., IFN-γ, IL-2, TNF-β), chemokines, and other such molecules produced by activated T cells and / or other leukocytes.
[0166] In some embodiments, antigen-specific immune responses are characterized by measuring the titer of anti-varicella-zoster virus antigen antibodies generated in subjects treated with an immunizing composition as provided herein. Antibody titer is a measurement of the amount of antibody (e.g., an antibody specific to a particular antigen (e.g., anti-VZV gE glycoprotein) or an epitope of an antigen) within the subject. Antibody titers are typically expressed as the reciprocal of the maximum dilution that provides a positive result. For example, enzyme-linked immunosorbent assay (ELISA) is a common assay used to determine antibody titers.
[0167] In some embodiments, antibody titers are used to assess whether a subject has been infected or to determine whether immunization is required. In some embodiments, antibody titers are used to determine the strength of an autoimmune response, to determine whether booster immunization is needed, to determine the effectiveness of a previous vaccine, and to identify any recent or prior infections. According to this disclosure, antibody titers can be used to determine the strength of an immune response induced in a subject by an immunizing composition (e.g., an RNA vaccine).
[0168] In some implementations, the anti-VZV gE antigen antibody titer generated in the subjects is at least 1 log higher than that in the control (unvaccinated subjects). For example, the anti-VZV gE antigen antibody titer generated in the subjects may be at least 1.5, at least 2, at least 2.5, at least 3 log, at least 3.5 log, or at least 4 log higher than that in the control. In some implementations, the anti-VZV gE antigen antibody titer generated in the subjects is 1, 1.5, 2, 2.5, or 3 log higher than that in the control. In some implementations, the anti-VZV gE antigen antibody titer generated in the subjects is 1 to 4 log higher than that in the control. For example, the anti-VZV gE antigen antibody titer generated in the subjects may be 1 to 1.5, 1 to 2, 1 to 2.5, 1 to 3, 1.5 to 2, 1.5 to 2.5, 1.5 to 3, 2 to 2.5, 2 to 3, or 2.5 to 4 log higher than that in the control.
[0169] In some implementations, the anti-VZV gE antigen antibody titer generated in the subjects is at least 2-fold higher than that of the control (received with the conventional vaccine GSK Shingrix®). For example, the anti-VZV gE antigen antibody titer generated in the subjects may be at least 1-fold, at least 1.5-fold, at least 2-fold, at least 2.5-fold, at least 3-fold, or at least 3.5-fold higher than that of the control GSK.
[0170] In some embodiments, the control is the anti-varicella-zoster virus antigen-antibody titer generated in subjects who have not received an immunization composition (e.g., an RNA vaccine). In some embodiments, the control is the anti-varicella-zoster virus antigen-antibody titer generated in subjects who have received the recombinant subunit vaccine Shingrix®.
[0171] In some embodiments, the effectiveness of the immune composition (e.g., an RNA vaccine) is measured in a rodent model. For example, the immune composition may be administered to a rodent model, and the induction of neutralizing antibody titers in the rodent model may be determined. Viral challenge studies may also be used to evaluate the efficacy of the vaccine of this disclosure. For example, the immune composition may be administered to a rodent model, the rodent model may be challenged with a virus, and the survival and / or immune response (e.g., T cell response (e.g., cytokine response)) of the rodent model may be determined.

[0173] Example 1: VZV gE mutant antigen design. gE, a highly glycosylated type I membrane protein, can be transported between the endoplasmic reticulum (ER), trans-Golgi network (TGN), and endosomes. The gE protein has several important domains related to its main function. (1) The TM transfer domain is composed of amino acids at positions 539-559; (2) A568YRV571 motif: mediates the transport of gE between the endoplasmic reticulum (ER), trans-Golgi network (TGN), and endoplasm; (3) Y582AGL585 motif: mediates the transport of gE between the endoplasmic reticulum (ER), trans-Golgi network (TGN), and endoplasm; (4) S593ES595T596DT598 motif: an important glycosylation site; mediates the transport of gE between the endoplasmic reticulum (ER), the trans-Golgi network (TGN), and the endoplasm. The intracellular carboxyl terminus of gE plays a decisive role in its intracellular transport. Based on the important structural domains and functions of the gE protein, a series of mRNA antigens targeting mutations in key structural and functional domains of gE and mutations in different truncated forms were designed (as shown in Figure 1). Using the wild-type gE gene sequence of VZV virus (reference NCBI virus strain sequence number QXN54923.1) as a reference, a series of 43 different gE variant mRNA sequences were designed: Table 1 summarizes the mRNAs encoding variant gE antigens with different C-terminal sequences. In the table, YK-VZV-004, YK-VZV-006, YK-VZV-045, and YK-VZV-007 correspond to the mutations or combinations of mutations in the published patents (US11643441B1, CN114081943A, US20230233671A1, and CN108472309A), respectively.

The transcription product was then purified by lithium chloride precipitation. 1) Add 30 μl of RNase-free H2O and 7.5 M lithium chloride (final lithium chloride concentration is 2.8 M) to 20 μl of the reaction mixture. 2) After mixing thoroughly, incubate at -20 ℃ for 2 h, centrifuge at 12000 rpm for 15 min, and discard the supernatant. Add 500 μl of 70% ethanol to wash the RNA precipitate; centrifuge at 12000 rpm for 5 min, repeat this step once, and collect the precipitate. 3) Air dry, add 100 μl of enzyme-free water to dissolve the mRNA precipitate, and store the purified RNA solution at -80℃. Measure the concentration and integrity of the mRNA. Preparation of mRNA-LNP (mRNA vaccine): Accurately weigh 20 mg of cationic lipids, DSPC, cholesterol, and DMG-PEG2000, dissolve them in anhydrous ethanol, and prepare a solution with a concentration of 10 mg / ml. Prepare a carrier mixture solution according to a molar ratio of 49:10:39.5:1.5 as the organic phase for later use. VZV mRNA was dissolved in 50 mM pH 4.0 citrate buffer and diluted to a 0.15 mg / ml solution for use as the aqueous phase. Using a BD 3 ml syringe, 2 ml of the organic phase was drawn, and using a BD 10 ml syringe, 7 ml of the aqueous phase was drawn. The left pump held the organic phase, and the right pump held the aqueous phase. The LNP intermediate solution was prepared in a microfluidic device. The preparation volume was 9.0 ml; the organic phase flow rate was 5.0 ml / min; the aqueous phase flow rate was 15 ml / min; and the LNP intermediate solution was collected. The LNP intermediate solution was diluted with 9 times its volume of PBS solution and concentrated by ultrafiltration on a small-scale ultrafiltration device with an ultrafiltration membrane pore size of 50 KD. When the concentration was about 10 ml, it was diluted with 4 times its volume of PBS solution and concentrated on the ultrafiltration device. Ultrafiltration was stopped when the final concentrated volume was less than 5 ml.

[0177] Example 6: Multiparameter Flow Cytometry (FCM) Detection of the Proportion of CD4+ T Cells and CD8+ T Cells Secreting IFN-γ and IL-2 in the Spleen of Balb / c Mice. The role of immune checkpoint inhibitors is to prevent T cell exhaustion. Immune cell function is assessed by detecting cytokine production in tumor samples. In the event of inflammation or host immune defense, T cells and NK cells respond by producing interferon-gamma (IFN-γ). Multiparameter flow cytometry (FCM) was used to quantitatively analyze IFN-γ-producing CD8+ or CD4+ T cells in the mouse spleen. Interferon-gamma (IFN-γ) is a soluble dimeric cytokine and the only member of the type II interferon family. It is primarily secreted by natural killer (NK) cells and natural killer T cells (NKT) and plays a role in innate immunity; in antigen-specific immunity, it is secreted by CD4 Th1 and CD8 cytotoxic T cells. IFN-γ or type II interferon plays an important role in innate and adaptive immunity against viral, certain bacterial, and protozoan infections. IFN-γ is an important macrophage activator and an inducer of type II major histocompatibility complex (MHC II) expression. Interleukin-2 (IL-2) is a cytokine belonging to the chemokine family. It is a cytokine with multiple cell origins (mainly produced by activated T cells) and multi-directional functions (mainly promoting lymphocyte growth, proliferation, and differentiation); it plays an important role in the body's immune response and antiviral infection, and can stimulate the proliferation of T cells that have been activated by specific antigens or mitogenic factors; it can activate T cells and promote cytokine production; it can stimulate NK cell proliferation, enhance NK killing activity and produce cytokines, induce the production of lymphokine-activated killer cells (LAK); promote B cell proliferation and antibody secretion; and activate macrophages. Detection method: FCM (multi-parameter flow cytometry). Test sample: Spleen harvested on day 56 of the immunized mouse model in Example 5. Objective: To determine the proportions of CD4+ T cells and CD8+ T cells secreting IFN-γ and IL-2 in the spleen of mice. Testing indicators: CD4+(IFN-γ+): The total number of CD4+ T cells that produce IFN-γ; CD4+ (IL-2+): The total number of CD4+ T cells that produce IL-2; CD4+(IFN-γ+IL-2+): The number of CD4+ T cells that simultaneously produce IFN-γ and IL-2; CD4+ (IFN-γ+ or IL-2+): The number of all CD4+ T cells that produce IFN-γ or IL-2; CD8+(IFN-γ+): The total number of CD8+ T cells that produce IFN-γ; CD8+ (IL-2+): The total number of CD8+ T cells that produce IL-2; CD8+(IFN-γ+IL-2+): The number of CD8+ T cells that simultaneously produce IFN-γ and IL-2; CD8+ (IFN-γ+ or IL-2+): The number of all CD8+ T cells that produce IFN-γ or IL-2.

[0178] Example 7: Detection of IFN-γ and IL-2 Cytokines Secreted by Balb / c Mouse Spleen Cells using Enzyme-Linked Immunospot Assay (ELISPOT). ELISPOT is a more sensitive detection method in cellular immunology research, capable of detecting antibody-secreting cells (ASCs) and cytokine-secreting cells at the single-cell level. It has higher sensitivity than ELISA and limiting dilution methods, detecting one cell secreting the protein from 200,000-300,000 cells. Furthermore, this method can perform functional detection on live cells after antigen stimulation, exhibiting high specificity, high reliability, and ease of operation. It has been widely used in the detection of CK-secreting cells or the assay of ASCs, and has gained widespread application in the immunology community both domestically and internationally. Lymphocytes locally produce cytokines after antigen stimulation, and these cytokines are captured by specific monoclonal antibodies (pre-coated) on the PVDF membrane at the bottom of the ELISPOT plate. After cell removal, the captured cytokines bind to biotin-labeled monoclonal antibodies, and subsequently to avidin labeled with alkaline phosphatase or wasabi peroxidase. Following substrate addition and color development, purple or reddish-brown spots appear on the PVDF membrane, indicating cytokine production by the cells. These spots are then automatically counted and analyzed using an ELISPOT Reader. The spleen organs were harvested from the mouse model of Example 6, and the levels of IFN-γ and IL-2 secreted by spleen cells after stimulation by the peptide library were detected on day 56 post-immunization. Sample processing: Procedure for isolating and cryopreserving mouse spleen cells. Elispot method: Detect the levels of IFN-γ and IL-2 in the supernatant of spleen cells after stimulation with a peptide library.

The number of seeded cells was recorded when the cell seeding density reached approximately 30% under a microscope. The cells were then cultured overnight. 2) Transfection: Transfect the overexpression stock solution (50 ng / well) and incubate for 48 h. 3) Washing: Remove the confocal dish, remove the culture medium directly, and add PBS to wash 1-3 times. Be careful not to shake it vigorously during washing. 4) Fixation: Add 200 μl of 4% paraformaldehyde solution to fix the cells, let them stand at room temperature for 15 min, wash 3 times with 1xPBS, and let them stand at room temperature for 5 min each time. 5) Permeability: Add 200 μl of 0.3% Tritonx-100 (diluted with 1×PBS) and punch holes for 10 min. Wash with 1×PBS 3 times, and let stand at room temperature for 5 min each time. 6) Blocking: Add 200 μl of immunostaining blocking solution and incubate at room temperature for 2 h. 7) Primary antibody conjugation: Add 100 μl of primary antibody diluted with antibody dilution buffer. The specific antibodies and dilution ratios are as follows: VZV gE antibody dilution ratio 1:100; 647-conjμgated GOLGA2 / GM130 antibody dilution ratio 1:100; CoraLite®594-conjμgated TGN46 antibody dilution ratio 1:100. Incubate overnight at 4°C in the dark, and remove the primary antibody (which can be recycled). 8) Primary antibody washing: Wash 3 times with 1×PBS, 5 min each time; wash away unbound primary antibody. 9) Secondary antibody incubation: Add 200 μl of fluorescent secondary antibody diluted with antibody dilution buffer. The antibody dilution ratio is 1:300. Incubate at room temperature in the dark for 1.5 h. 10) Secondary antibody washing: Wash 3 times with 1×PBS for 5 min each time to remove unbound secondary antibody and avoid non-specific staining. 11) Nucleus staining and mounting: Remove the frame, add one drop of DAPI stain stock solution to each well, cover and store at 4 degrees Celsius away from light. 12) Take X-rays using a confocal microscope. The settings of this invention are compared as follows: LNP: Blank LNP without mRNA vaccine; Shingrix®: Shingrix® is a recombinant protein subunit vaccine manufactured and marketed by GlaxoSmithKline.

Based on this, this project designed YK-VZV-004 (SEQ ID NO:15), which maintains the same mutation site and truncated length as the herpes zoster mRNA vaccine antigen sequence gE(1-573aa) Y569A reported in Moderna patent (US11643441B1). YK-VZV-004:gE(1-573aa) Y569A was used as one of the positive controls for antigen screening. The immunogenicity of the vaccine was evaluated together with the newly designed mutation and mutation combination sequences of this invention. Specific results are shown in the examples.

Based on this, this project designed YK-VZV-006 (SEQ ID NO:19), which maintains the same combination of mutation sites (Y569A, S593A, S595A, T596A, T598A) as SEQ ID No.2 mentioned in patent (CN114081943A). YK-VZV-006:gE(1-623aa), (Y569A,S593A,S595A,T596A,T598A) were also used as one of the controls for antigen screening in this invention. Together with the newly designed mutation and mutation combination sequences of this invention, the immunogenicity of the vaccine was evaluated. The specific results are shown in the examples.
[0182] Comparative Example 3: Based on the herpes zoster mRNA vaccine antigen sequence reported in US20230233671A1, it was found that the patent discloses a mutant VZV gE protein Y582A. Based on this, this project designed YK-VZV-045 (SEQ ID NO: 171), which maintains the same mutation site combination Y582A as the mRNA vaccine antigen sequence mentioned in US20230233671A1. YK-VZV-045 was also used as one of the controls for antigen screening in this invention, and together with the newly designed mutant and mutant combination sequences of this invention, the immunogenicity of the vaccine was evaluated.

YK-VZV-007 was also used as one of the controls for antigen screening in this invention, and the immunogenicity of the vaccine was evaluated together with the newly designed mutant and mutant combination sequences of this invention. Specific results are shown in the examples.
[0184] Results Summary and Analysis: In vitro expression results of VZV gE antigen variants: Western blot analysis of 43 VZV gE antigen variants (Figure 2) showed that the expression level of YK-VZV-002 antigen protein was extremely low or almost non-existent; the expression results of YK-VZV-041, YK-VZV-042, and YK-VZV-043 antigen proteins were negative, indicating no expression; therefore, the above four sequences could not be used as candidate antigens for herpes zoster mRNA vaccines and were therefore excluded. Other antigen variants all showed significant protein expression, with the expressed proteins ranging from approximately 63 kDa to 75 kDa, consistent with the theoretical antigen design. They can serve as effective candidate antigens for further immunogenicity screening and evaluation. The Western blot results above show that YK-VZV-001, YK-VZV-003, YK-VZV-004 (Comparative Example 1), YK-VZV-006 (Comparative Example 2), YK-VZV-007 (Comparative Example 4), YK-VZV-009, YK-VZV-010, YK-VZV-011, YK-VZV-012, and YK-VZV-003 are all related to the above-mentioned Western blot experiments.

[0186] Cellular Immunotherapy Results (FCM) of VZV gE Antigen Variant: Cellular immunity, especially T-cell immunity, plays a crucial role in VZV infection. Studies have shown that cell-mediated immune effects are an important indicator for evaluating the efficacy of shingles vaccines. To further evaluate the specific cellular immune response induced in mice immunized with the aforementioned antigen mutant mRNA, Example 6 used FCM to detect the specific CD4+ T cell and CD8+ T cell immune responses induced in mice immunized with VZV gE antigen mRNA. Using the Shingrix® positive control as a standard, and based on the fact that the gE-specific antibody IgG titer effect was also superior to the YK-VZV-007 sequence, the following 14 variants were further extracted, including: YK-VZV-009, YK-VZV-011, YK-VZV-013, YK-VZV-014, YK-VZV-010, YK-VZV-012, YK-VZV-018, YK-VZV-020, YK-VZV-030, YK-V The spleens of mice immunized with ZV-031, YK-VZV-038, YK-VZV-021, YK-VZV-024, YK-VZV-028, and four control sequences, including YK-VZV-004 (Comparative Example 1), YK-VZV-006 (Comparative Example 2), YK-VZV-045 (Comparative Example 3), and YK-VZV-007 (Comparative Example 4), were measured on day 56.

Alternatively, the proportion of IFN-γ+ CD8+ T cells was less than 5%, significantly lower than the optimal proportion of secretory cells for mRNA vaccines (5.20~8.10%), less than 4.0 times that of the Shingrix® positive control vaccine, and about 1 to 2 times that of YK-VZV-007; Alternatively, if the proportion of IL-2+ CD8+ T cells is less than 0.2%, its efficacy is not significantly different from or even worse than that of Shingrix® positive control vaccine and YK-VZV-007, being only about 0.8 to 1.6 times that of Shingrix® positive control vaccine and about 0.5 to 1.0 times that of YK-VZV-007, therefore it is excluded; The message is as follows: Table 29. mRNA vaccine-induced production of IFN-γ or IL-2+ CD8+ T cells -2 test substance CD8+ IFN-γ+ CD8+ IL-2+ CD8+ (IFN-γ+ or IL-2+) CD8+ (IFN-γ+) Compared to Shingrix® (times) Compared to YK-VZV-007 (times) CD8+ (IL-2+) Compared to Shingrix® (times) Compared to YK-VZV-007 (times) CD8+ (IFN-γ+ or IL-2+) Compared to Shingrix® (times) Compared to YK-VZV-007 (times) YK-VZV-012 4.20% 3.82 2.21 0.10% 0.83 0.56 4.20% 3.82 2.63 YK-VZV-028 3.10% 2.82 1.63 0.40% 3.33 2.22 3.10% 2.82 1.94 YK-VZV-038 2.40% 2.18 1.26 0.20% 1.67 1.11 2.30% 2.09 1.44 YK-VZV-031 1.80% 1.64 0.95 0.10% 0.83 0.56 1.90% 1.73 1.19 LNP 0.00% - - 0.00% - - 0.00% - - Shingrix® 1.10% 1.00 0.58 0.12% 1.00 0.67 1.10% 1.00 0.69 YK-VZV-004 (Comparative Example 1) 2.80% 2.55 1.47 0.21% 1.75 1.17 2.70% 2.45 1.69 YK-VZV-006 (Comparative Example 2) 1.90% 1.73 1.00 0.20% 1.67 1.11 1.50% 1.36 0.94 YK-VZV-045 (Comparative Example 3) 1.50% 1.36 0.79 0.16% 1.33 0.89 1.40% 1.27 0.88 YK-VZV-007 (Comparative Example 4) 1.90% 1.73 1.00 0.18% 1.50 1.00 1.60% 1.45 1.00 The YK-VZV-012 and YK-VZV-031 mRNA vaccines induced a lower proportion of IL-2+ CD8+ T cells compared to the Shingrix® vaccine and YK-VZV-007 (Comparative Example 4), and were therefore excluded. The YK-VZV-028 and YK-VZV-038 mRNA vaccines induce only about twice the proportion of IFN-γ+ CD8+ T cells and the total proportion of IFN-γ+ and IL-2+ CD8+ T cells compared to the Shingrix® vaccine, which is significantly lower than the sequence designed in part A above (more than seven times lower). Therefore, their immune efficacy is poor and they are not suitable as candidate sequences for shingles vaccines. Therefore, based on the above results, the sequences with significant advantages in overall immunization effect include: YK-VZV-010, YK-VZV-013, YK-VZV-011, YK-VZV-020, and YK-VZV-018, which have excellent immunization effects and are significantly better than other sequences, among which YK-VZV-010 has the best effect.

To verify the consistency between the above partial IgG antibody titers and partial VZV gE antigen variant cellular immunoassay results, the following partial test substances (including YK-VZV-009, YK-VZV-010, YK-VZV-011, YK-VZV-013, YK-VZV-020, YK-VZV-014, YK-VZV-012, YK-VZV-018, YK-VZV-021, YK-VZV-024, YK-V ZV-028, YK-VZV-030, YK-VZV-031, YK-VZV-038, YK-VZV-004 (Comparative Example 1), YK-VZV-045 (Comparative Example 3), and YK-VZV-007 (Comparative Example 4) were used to measure serum samples from immunized mice on day 56. The titer of VZV-binding-gE antibody IgG in the serum was detected according to the method described in Example 5. The results are shown in the table below.

The antibody GMT distribution ranged from 270 to 750 × 10⁴. Specifically, the antibody GMT of YK-VZV-010, YK-VZV-011, YK-VZV-018, YK-VZV-020, and YK-VZV-013 reached over 650 × 10⁴, which is more than 4.0 to 5.0 times higher than the Shingrix® vaccine and more than twice that of YK-VZV-007 (Comparative Example 4). Furthermore, all were significantly superior to YK-VZV-004 (Comparative Example 1) and YK-VZV-045 (Comparative Example 3). Based on the above IgG antibody titers and CD4+ T cell and CD8+ T cell detection results, the five antigens YK-VZV-010, YK-VZV-013, YK-VZV-011, YK-VZV-020, and YK-VZV-018 showed the best cellular immunization effects and were therefore selected as candidate antigens for further detection and analysis using the ELISpot method.
[0190] VZV gE antigen variant cellular immune factor results (ELISOPT). ELISOPT is the gold standard for screening and evaluating the antigen-specific T-cell immune efficacy of candidate vaccines. It can be used to distinguish different subsets of activated T cells by cytokines, such as T helper (Th) type 1 cells (producing IFN-γ, IL-2, IL-6, IL-12, IL-21 and TNF-α cytokines), Th2 (producing IL-4, IL-5, IL-10 and IL-13 cytokines) and Th17 (producing IL-17 cytokine) cells. Five optimal antigen sequences (YK-VZV-010, YK-VZV-013, YK-VZV-011, YK-VZV-020, and YK-VZV-018) were selected based on the combined results of IgG and cytokine detection. These, along with Comparative Example 1 (YK-VZV-004), Comparative Example 2 (YK-VZV-006), Comparative Example 3 (YK-VZV-045), and Comparative Example 4 (YK-VZV-007), and using LNP and Shingrix® as controls, were further detected using the ELISpot method. The results are as follows: 1) The amount of IFN-γ cytokine secreted by T cells stimulated by the mRNA vaccine was above 500 SFU, with the highest reaching nearly 600 SFU, which is about 16 to 19 times that of the Shingrix® positive control and 2.5 to 3.0 times that of control 4 (YK-VZV-007); and significantly better than the cytokines secreted by the mRNA vaccines corresponding to control 1 (YK-VZV-004), control 2 (YK-VZV-006) or control 3 (YK-VZV-045). Among them, the mRNA vaccine prepared with the YK-VZV-010 sequence reached a maximum of 598.8 SFU, which is 18.7 times that of the Shingrix® positive control and nearly 3 times that of the YK-VZV-007 control. The IFN-γ secretion levels from high to low were YK-VZV-010, YK-VZV-018, YK-VZV-011, YK-VZV-020, and YK-VZV-013, with no significant differences between groups, and all groups showed good and significant immune effects.

Among them, the mRNA vaccine prepared with the YK-VZV-010 sequence reached a maximum of 614.5 SFU, which is 16.00 times that of the Shingrix® positive control and more than 3 times that of the YK-VZV-007 control. The IL-2 secretion levels from high to low were YK-VZV-010, YK-VZV-011, YK-VZV-018, YK-VZV-013, and YK-VZV-020, with no significant differences between groups, and all groups showed good and significant immune effects.

[0191] VZV gE antigen variant cellular localization results: 1) C-terminal truncation and the "A568Y569R570V571" motif mutation reduced the localization of gE antigen to the trans-Gorgistrite network. The "A568Y569R570V571" motif (SEQ ID NO:184) is a transport motif that targets the gE peptide to the trans-homogeneous network. YK-VZV-018 (SEQ ID NO:63) and YK-VZV-020 (SEQ ID NO:71) are truncated peptides encoding the terminal 50 amino acids (retaining 1-573 amino acids) with a deleted C-terminal region, and mutations at any site in the A568Y569R570V571 sequence (e.g., mutations at A568D and Y569K sites). Results in Example 8 showed that both the YK-VZV-018 and YK-VZV-020 variants resulted in reduced localization of the gE peptide to the trans-homogeneous network and enhanced cell membrane expression. 2) Any combination of mutant motifs "A568Y569R570V571" or "Y582A583G584L585" reduces the localization of gE antigen into the trans-Gyrgiform network. YK-VZV-011 (SEQ ID NO:35) and YK-VZV-013 (SEQ ID NO:43) encode the full-length gE polypeptide and contain mutations at various sites of the "A568Y569R570V571" motif (SEQ ID NO:184). In addition, the "Y582A583G584L585" endocytosis motif (SEQ ID NO:185) of YK-VZV-013 is also mutated (e.g., Y582A). The results of Example 8 show that gE antigen is expressed on the cell membrane in any combination of "A568Y569R570V571" or "Y582A583G584L585" mutated motifs. 3) Full-length gE variants with the "A593E594A595A596D597A598" mutation motif, Y569K, and Y582A mutations are reduced in localization to the trans-homogeneous network. YK-VZV-010 (SEQ ID NO:31) encodes a full-length gE polypeptide, with the A593E594A595A596D597A598 (SEQ ID NO:183) sequence replacing the "S593E594S595T596D597T598" motif (SEQ ID NO:182). YK-VZV-010 replaces the Ser / Thr-rich "SSTT" acidic cluster with an Ala-rich sequence. Furthermore, the YK-VZV-010 mRNA vaccine also possesses Y569K and Y582 mutations. Results in Example 8 showed enhanced cell membrane expression of the YK-VZV-010 gE polypeptide. Each of the above variants has the modification of reducing the localization of the gE protein into the trans-Gyrtisteine network and enhancing its transport to the serous membrane.

Such results are surprising. Among these sequences, the mutation combinations YK-VZV-010 (gE full length; Y569K; Y582A; S593A; S595A; T596A; T598A), YK-VZV-011 (gE full length; A568D; Y569K; R570E; V571K), YK-VZV-013 (gE full length; A568D; Y569K; R570E; V571K; Y582A), YK-VZV-018 (gE 1-573aa, A568D), and YK-VZV-020 (gE 1-573aa, Y569K) are preferred. The table below shows the complete sequence information and their numbers for this application. Taking the antigen sequence of YK-VZV-001 as an example, SEQ NO ID: 2 and 3 are the nucleic acid sequence ("ORF-NT") and amino acid sequence ("ORF-AA") of the open reading frame of antigen YK-VZV-001, respectively; SEQ NO ID: 1 and 4 are the DNA sequence ("DNA") and mRNA sequence ("mRNA") of antigen YK-VZV-001, respectively.
