Description

DOCKET NO: 2028-011 PCT TITLE mRNA PRIMING VACCINE COMPOSITION AND METHOD OF USE THEREOF

[0001] The present application claims priority of US Provisional Patent application No.63 / 623,446, filed January 22, 2024, which is incorporated herein by reference in its entirety. FIELD

[0002] The present disclosure relates generally to vaccine development and, in particular, to compositions and methods for vaccination against HIV-1. BACKGROUND

[0003] Nucleic acid vaccines have emerged as promising alternatives to conventional vaccine approaches.

[0004] The mRNA vaccine field is developing extremely rapidly due to the improvement of stability and translation of mRNA, and in vivo delivery efficiency, which highlighted by the approval of SARS-Cov-2 vaccine from Pfizer / BioNtech, Moderna, and others.

[0005] mRNA vaccine has many advantages such as high potency, capacity for rapid development and potential for low-cost manufacture and relatively safe administration.

[0006] However, the immunogenicity of mRNA vaccines is far from ideal, such as the short durability of immune responses induced by mRNA vaccines.

[0007] Also heterologous prime-boost vaccination has emerged as the more powerful strategy for future vaccine development and how to apply such concept to mRNA vaccine usage is the key discovery of the current application. SUMMARY

[0008] One aspect of the present application relates to a method for immunizing a subject against a pathogen, comprising the steps of: (1) administering to the subject an effective amount of a prime vaccine, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more immunogens and / or modified immunogens from the pathogen; and (2) administering to the subject an effective amount of a boost vaccine, WAS:164427.1wherein the booster vaccine comprises a non-mRNA vaccine modality against the pathogen, wherein the boost vaccine is administered after the administration of the prime vaccine. In some embodiments, the pathogen is HIV-1 and the method comprises the steps of (1) administering to the subject an effective amount of a prime vaccine, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more HIV-1 envelope immunogens and / or modified HIV-1 envelope immunogens; and (2) administering to the subject an effective amount of a boost vaccine (in any non-mRNA vaccine modality), wherein the booster vaccine comprises one or more HIV-1 envelope immunogens and / or modified HIV-1 envelope immunogens that are encoded in the one or more mRNA constructs in the prime vaccine, or wherein the booster vaccine comprises one or more HIV-1 envelope immunogens and / or modified HIV-1 envelope immunogens that are not the same (such as from different viral variants) as encoded in the one or more mRNA constructs in the prime vaccine, wherein the boost vaccine is administered after the administration of the prime vaccine. Examples of the HIV-1 envelope proteins include, but are not limited to, gp120, gp140, gp160 or trimeric HIV-1 envelope glycoprotein.

[0009] Another aspect of the present application relates to a method for introducing an immune response against HIV-1 in a subject, comprising the steps of: (1) administering to the subject an effective amount of a prime vaccine, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more HIV-1 env immunogens and / or modified HIV-1 env immunogens ; and (2) administering to the subject an effective amount of a boost vaccine (in any non-mRNA vaccine modality), wherein the booster vaccine comprises one or more HIV-1 env immunogens and / or modified HIV-1 env immunogens that are encoded in the one or more mRNA constructs in the prime vaccine, or wherein the booster vaccine comprises one or more HIV-1 envelope immunogens and / or modified HIV-1 envelope immunogens that are not the same (such as from different viral variants) as encoded in the one or more mRNA constructs in the prime vaccine, wherein the boost vaccine is administered after the administration of the prime vaccine. The prime vaccine and / or the boost vaccine may be monovalent or polyvalent. The HIV-1 env immunogens and modified HIV-1 env immunogens may comprise HIV-1 gp120, gp140, gp160, trimeric HIV-1 envelope glycoprotein and other forms of HIV-1 envelope immunogens.

[0010] Another aspect of the present application relates to an mRNA priming HIV-1 vaccine formulation, comprising: (1) a prime component comprising a mRNA construct encoding an HIV-1 env immunogen or a modified HIV-1 env immunogen, such as in the form of gp120, gp140, gp160, trimeric HIV-1 envelope glycoprotein, or other modified env 2 WAS:164427.1immunogens and (2) a boost component (in any non-mRNA vaccine modality) comprising the immunogen encoded in the mRNA construct or immunogen that is not the same (such as from different viral variants) as encoded in the mRNA, wherein the prime component and boost components are formulated for separate administrations.

[0011] One of ordinary skill will understand that the differing embodiments disclosed in this application can all be used either independently or in combination with each other and there is no limitation implied on such combinations by the order or manner in which embodiments are disclosed.

[0024] All references, patents and patent applications disclosed herein are incorporated by reference with respect to the subject matter for which each is cited, which in some cases may encompass the entirety of the document. I. Definitions

[0025] All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and / or ordinary meanings of the defined terms.

[0026] The terms “a”, “an,” or “the” as used in the specification and claims, unless clearly indicated to the contrary, should be understood to mean “at least one” or “one or more,” unless the content clearly dictates otherwise.

[0027] The phrase “and / or,” as used herein in the specification and claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and / or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and / or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and / or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. 5 WAS:164427.1

[0028] As used herein in the specification and claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and / or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

[0029] In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. Further, if the disclosure describes “a composition comprising A and B”, the disclosure also contemplates the alternative embodiments “a composition consisting of A and B” and “a composition consisting essentially of A and B”.

[0030] Where ranges are given, endpoints are included. Further, it is to be understood that unless otherwise indicated or otherwise evident from the context and understanding of one of ordinary skill in the art, values that are expressed as ranges can assume any specific subrange within the stated ranges in different embodiments of the invention, or any subrange defined by any pair of integers within a stated range, unless the context clearly dictates otherwise.

[0031] It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited. 6 WAS:164427.1

[0032] The term “heterologous prime-boost vaccination”, as used herein, refers to two or more vaccine modalities administrated sequentially.

[0033] The term “single immunogen”, as used herein, refers to one immunogen from the pathogen.

[0034] The term “multiple immunogens”, as used herein, refers to two or more immunogens from the same pathogen.

[0035] The term “monovalent”, as used herein, refers to one variant of an immunogen from the pathogen.

[0036] The term “polyvalent”, as used herein, refers to multiple variants of the same immunogen from the pathogen.

[0037] The term "vaccine" refers to a composition that induces an immune response in the recipient or host of the vaccine. A vaccine may induce a humoral (e.g., antibody, neutralizing antibody, other functional antibodies etc.) response to one or more immunogens, cell-mediated immune response (e.g., helper T lymphocyte, or cytotoxic T lymphocyte (CTL)) response against one or more immunogens, or both in a recipient so as to provide partial or complete protection against e.g., current or subsequent microbial infections or disease conditions characterized by the presence of e.g., one or more neoantigens or cancer antigens in the recipient.

[0038] The term "vaccine", as used herein, refers to a composition comprising at least one immunologically active component (i.e, an immunogen) that induces an immune response in the recipient or host of the vaccine and may possibly, but not necessarily, include one or more additional components that enhance the immunological activity of the active component. Examples of vaccines include, but are not limited to, live attenuated vaccines, inactivated vaccines, recombinant protein vaccines, viral particle vaccines, sugar-based vaccines (conjugated or natural), bacterial vector vaccines, viral vector vaccines, and nucleic acid vaccines such as mRNA vaccines and DNA vaccines.

[0039] A vaccine of the present application can induce antibody responses and / or cell-mediated immune response to a target pathogen in the recipient as protection against current or future target pathogen infections, including protection against infection upon subsequent challenge with target pathogen. Antibodies , CD4+ T cell or CD8+ T cell generated in the vaccinated host can provide this protection.

[0040] The term “vaccine modality” refers to the mode that an immunogen or immunogens is present in a vaccine. Examples of vaccine modalities include, but are not limited to, live attenuated vaccine, inactivated vaccine, recombinant protein vaccine, viral 7 WAS:164427.1like particle vaccine, viral vector vaccine, polysaccharide conjugate vaccine, toxoid vaccine, and nucleic acid vaccine such as mRNA vaccine and DNA vaccine.

[0041] The term "vaccination" refers to the administration of antigenic material to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccination can prevent or ameliorate of one or more symptoms associated with microbial infection or antigen- or epitope-specific cell associated with a disease, such as cancer; and / or lessening of the severity or frequency of one or more symptoms associated with the foregoing disease conditions.

[0042] The term “single-modality vaccination” refers to a vaccination process using vaccine or vaccines of the same modality (e.g., vaccination with inactivated vaccines).

[0043] The term “multiple-modality vaccination” refers to a vaccination process using vaccines of two or more modalities. (e.g., vaccination with a DNA prime vaccine first, followed by a protein boost vaccine).

[0044] The terms “immunogen” is referred to a substance or molecule from the pathogen capable of eliciting an immune response and generating specific antibodies (humoral response) or cell-mediated response against it. As such, the immunogen is capable of being recognized by components of the immune system, such as lymphocytes. An immunogen can be as small as a single epitope, or larger, and can include multiple epitopes. As such, the size of an immunogen can be as small as about 5-12 amino acids (e.g., a peptide) and as large as: a partial protein, a full-length protein, including a multimer and fusion protein, or a chimeric protein. In addition, immunogens can be polynucleotides, such as mRNAs and DNAs, or carbohydrates or attenuated / killed pathogen. An immunogen may be from a bacterium, virus, protozoan or fungus.

[0045] The term "epitope" or "antigenic epitope" includes any molecule, structure, amino acid sequence, or protein determinant that is recognized and specifically bound by a cognate binding molecule, such as an immunoglobulin, or other binding molecule, domain, or protein. Epitopic determinants generally contain chemically active surface groupings of molecules, such as amino acids or sugar side chains, and can have specific three-dimensional structural characteristics, as well as specific charge characteristics. Where an immunogen is or comprises a peptide or protein, the epitope can be comprised of consecutive amino acids (e.g., a linear epitope), or can be comprised of amino acids from different parts or regions of the protein that are brought into proximity by protein folding (e.g., a discontinuous or conformational epitope), or non-contiguous amino acids that are in close proximity irrespective of protein folding. 8 WAS:164427.1

[0046] As used herein, the term “multi-immunogen vaccine” refers to a vaccine modality that includes more than one immunogen.

[0047] As used herein, the term “DNA vaccine” refers to a type of nucleic acid vaccines that introduces a specific immunogen-coding DNA sequence into the cells of a host as a mechanism deliver one or more immunogens for the purpose of inducing immunogen specific immune responses in the host. The immunogen-coding DNA, when expressed in a subject, is translated into an antigenic protein or polypeptide that induces an immune response.

[0048] As used herein, the term “mRNA vaccine” refers to a type of nucleic acid vaccines that uses messenger RNA (mRNA) to produce an immunogen specific immune response. The vaccine delivers molecules of immunogen-encoding mRNA into host cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus). These protein molecules stimulate an adaptive immune response that teaches the body to identify and destroy the corresponding pathogen.

[0049] As used herein, the term “live attenuated vaccine,” refers to a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by "killing" the pathogen (inactivated vaccine).

[0050] As used herein, the term “inactivated vaccine,” refers to a vaccine that uses the killed version of a pathogen (e.g., a bacterium or virus) without causing a disease.

[0051] As used herein, the term “recombinant protein vaccine,” refers a vaccine that uses a recombinant protein as an immunogen.

[0052] As used herein, the term “viral vector vaccine,’ refers to a vaccine that uses a recombinant virus as a vector to deliver an immunogen.

[0053] As used herein, the term “viral like particle vaccine (VLP),” refers to a vaccine that uses molecules that closely resemble viruses, but are non-infectious because they can not replicate in the host. Viral like particles contain repetitive, high density displays of viral surface proteins that present conformational immunogen epitopes that can elicit immunogen specific T cell and B cell immune responses. Since VLPs cannot replicate, they provide a safer alternative to attenuated viruses.

[0054] As used herein, the term “polysaccharide conjugate vaccine,” refers to a vaccine that conjugate a polysaccharide immunogen from bacteria to a protein carrier, thereby improving the immunogenicity of the polysaccharide immunogen. 9 WAS:164427.1

[0055] As used herein, the term “toxoid vaccine,” refers to a vaccine that is made of detoxified toxin of a pathogen that no longer causes a disease. The vaccine creates immunity to the toxin in order to achieve the control of a pathogen.

[0056] As used herein, the term “heterologous prime-boost vaccination” refers to a vaccination process in which a prime vaccine (e.g., a DNA vaccine) is administered first (once or multiple times), followed with one or more administrations of a boost vaccine (e.g., a recombinant protein vaccine). This is different from the “homologous prime-boost vaccination” in which the prime vaccine and boost vaccine use the same vaccine modality. The prime vaccine, or the boost vaccine, or both can be monovalent or polyvalent, no matter whether it is the “homologous prime-boost vaccination” or the “heterologous prime-boost vaccination”.

[0057] As used herein, the term “adjuvant” refers to a compound or mixture that enhances an immune response. The term "adjuvant" refers to an agent that when administered concurrently with the vaccine composition of the present application, accelerates, prolongs, enhances and / or boosts the immune response thereto. Adjuvants can enhance an immune response by several mechanisms including, e.g., lymphocyte recruitment, stimulation of B and / or T cells, stimulation of dendritic cells and / or stimulation of macrophages.

[0058] As used herein, the term “adjuvanted recombinant protein or polypeptide” refers to a protein immunogen or polypeptide immunogen that is mixed with, or formed a complex with, an adjuvant.

[0059] As used herein, the term “polynucleotide” or “nucleic acid” refers to both DNA and mRNA molecules. In other words, a polynucleotide can be a DNA molecule or an mRNA molecule.

[0060] The terms “codon optimized” and “codon optimization” refer to a process for modifying a nucleic acid sequence according to one or more of the following: (1) to match codon frequencies in a host target; (2) to promote increased expression; (3) to ensure proper folding; (4) to provide a GC content suitable for increasing mRNA stability or reducing secondary structures; (5) to minimize tandem repeat codons or base runs that may impair gene construction or expression; (6) to customize transcriptional and translational control regions; (7) to insert or remove protein trafficking sequences; (8) to remove / add post translation modification sites in an encoded protein (e.g. glycosylation sites); (9) to add, remove or shuffle protein domains; (10) to insert or delete restriction sites; (11) modify ribosome binding sites and mRNA degradation sites; (12) to adjust translational rates to allow the various domains of the protein to fold properly; or (13) to reduce or eliminate problem 10 WAS:164427.1secondary structures within the polynucleotide. Codon optimization tools, algorithms and services are known in the art—non-limiting examples include services from GeneArt (Life Technologies), DNA2.0 (Menlo Park Calif.) and / or proprietary methods.

[0061] The term "expression vector" refers to a gene construct that is capable of expressing a polypeptide (e.g., a mRNA, a guide RNA, shRNA or miRNA) in a cell. Expression vectors may be, for example, plasmids, viral vectors, and bacterial vectors.

[0062] An expression vector typically comprises (1) a polynucleotide coding sequence encoding the polypeptide to be expressed and (2) multiple regulatory sequences operably linked to the coding sequence. The regulatory sequence is capable of effecting the expression of the coding sequence in a suitable host. Such regulatory sequences may include promoters, enhancers, mRNA ribosome binding sites, introns, internal ribosome binding sequences, and sequences which control termination of transcription and translation. Once transfected into a suitable host, the expression vector may replicate and function independently of the host genome.

[0063] The term "operably linked" refers to the association of two or more nucleic acid molecules on a single nucleic acid fragment so that the function of one is affected by the other. For example, a promoter is operably linked with a coding sequence when it is capable of affecting the expression of that coding sequence (i.e., the coding sequence is under the transcriptional control of the promoter). "Unlinked" means that the associated genetic elements are not closely associated with one another and the function of one does not affect the other.

[0064] As used herein, the term "wild type,” “prototype” and “original” are used with reference to the original target isolate, including polynucleotides and proteins thereof

[0065] As used herein, the phrases “primary viral isolate" and "primary isolate" in reference to nucleic acid or amino acid sequences refer to a nucleic acid or amino acid sequence present in cells of individuals naturally infected with a virus, such as HIV-1. A primary viral isolate is a viral isolate that has been expanded and maintained only in primary cells, and has not been expanded and maintained in cell lines. Thus, a primary isolate differs from what is referred to as a "laboratory strain.".

[0066] As used herein, the phrases “variant virus”, “variant strain” and “variant of a virus” are used interchangeably and refer to a virus strain that differs from the original virus strain by one or more nucleotide in the viral genome. Variants of the original strain (such as in the case of HIV-1) may be divided into Groups, such as M group and within the M group, 11 WAS:164427.1further divided into clades (subtypes), such as clade A, B, C, D, A / E. Within each clade, there are a vast variety of strains that are slightly different from each other.

[0067] As used herein, the phrase “variant of an immunogen” refers to different versions or subtypes / strains of an immunogen. For example, the envelope glycoprotein gp120 (gp120) of different HIV-1 subtypes / strains, such as HIV-1 gp120-A / 92UG037.1, HIV-1 gp120-B / JRFL or 92US715.6, HIV-1 gp120-C / 93MW965.26, HIV-1 gp120- D / 92UG021.16, and HIV-1 gp120 A / E / consensus are variants of HIV-1 gp120. As used herein, the phrase “modified immunogen” or “modified forms of an immunogen” refers an immunogen with one or more modifications from its original / native immunogen sequences. Modified forms of an immunogen include fragments and polymers of the immunogen. For example, modified forms of HIV-1 gp120 include HIV-1 gp120 with substitutions, deletions and additions in its amnio acid sequence, fragments of HIV-1 gp120, and trimers of HIV-1 gp120. Modified immunogens include immunogens (such as viral envelope proteins) with optimized structural designs. Optimized structural designs is a well- accepted technical concept and is crucial for developing effective vaccines. Different strategies can be applied based on different targets and applications such as retaining the prefusion state for certain envelope glycoprotein.

[0068] The term “HIV-1 env immunogens,” as used herein, refers to all immunogenic forms of HIV-1 envelope proteins and modified forms thereof. Examples of HIV-1 envelope proteins include, but are not limited to, HIV-1 gp120, HIV-1 gp140, HIV-1 gp160, and HIV- 1 trimeric envelope glycoprotein.

[0069] The phrase "effective amount" of an agent, as used herein, is that amount sufficient to affect beneficial or desired results, for example, clinical results, and, as such, an "effective amount" depends upon the context in which it is being applied. For example, in the context of administering a vaccine composition, an effective amount refers to an amount sufficient to induce an immune response or provide immunity against HIV-1, as compared to responses (or lack thereof) obtained without administration of the agent. In general, an effective amount of the DNA / RNA and / or protein vaccines provide an induced or boosted immune response in a subject.

[0070] As used herein, the term "homology" refers to the overall relatedness between polymeric molecules, e.g. between nucleic acid molecules (e.g. DNA molecules and / or RNA molecules) and / or between polypeptide molecules. In some embodiments, polymeric molecules are considered to be "homologous" to one another if their sequences are at least about 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5% identical or similar. The term 12 WAS:164427.1"homologous" necessarily refers to a comparison between at least two sequences (polynucleotide or polypeptide sequences). In accordance with the present invention, two polynucleotide sequences are considered to be homologous if the polypeptides they encode are at least about 80%, 90%, 95%, or even 99% to one another. In some embodiments, homologous polynucleotide sequences are characterized by the ability to encode a stretch of at least 4-5 uniquely specified amino acids.

[0071] As used herein, the term "identity" or “sequence identity” refers to the overall relatedness between polymeric molecules, e.g., between oligonucleotide molecules (e.g. DNA molecules and / or mRNA molecules) and / or between polypeptide molecules.

[0072] Calculation of the percent identity of two polynucleotide sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second nucleic acid sequences for optimal alignment and non-identical sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least about 80%, 90%, 95%, 96%, 97%, 98%, 99% or 100% identical to a reference sequence. The nucleotides at corresponding nucleotide positions are then compared. When a position in the first sequence is occupied by the same nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which needs to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. The percent identity between two nucleotide sequences can be determined using conventional methods known in the art at the time the present invention was made.

Subject

[0081] The subject can be any subject capable of generating an immune response against the pathogen. In some embodiments, the subject is a mammal. In some embodiments, the subject is a human subject. Pathogen

[0082] The pathogen can be any microorganism that is capable of inducing an infectious disease in a subject.

In some embodiments, the pathogen is a virus selected from the group consisting of human immunodeficiency viruses (HIV), influenza A viruses including subtype H1N1, H3N2, H7N9, or H5N1, influenza B viruses, influenza C viruses, rotavirus A, rotavirus B, rotavirus 16 WAS:164427.1C, rotavirus D, rotavirus E, human coronaviruses, SARS coronaviruses, MERS coronaviruses, human adenoviruses, human papillomaviruses (HPV), parvoviruses, molluscum contagiosum viruses, JC viruses (JCV), BK viruses, Merkel cell polyomaviruses, coxsackie A viruses, noroviruses, Rubella viruses, lymphocytic choriomeningitis viruses (LCMV), Dengue viruses, Zika viruses, chikungunya, Eastern equine encephalitis viruses (EEEV), Western equine encephalitis viruses (WEEV), Venezuelan equine encephalitis viruses (VEEV), Ross River viruses, Barmah Forest viruses, yellow fever viruses, measles viruses, mumps viruses, respiratory syncytial viruses, rinderpest viruses, California encephalitis viruses, hantaviruses, rabies viruses, ebola viruses, marburg viruses, herpes simplex virus-1 (HSV-1), herpes simplex virus-2 (HSV-2), varicella zoster viruses (VZV), Epstein-Barr viruses (EBV), cytomegaloviruses (CMV), herpes lymphotropic viruses, roseoloviruses, Kaposi's sarcoma-associated herpesviruses, hepatitis A viruses, hepatitis B viruses, hepatitis C viruses, hepatitis D viruses, hepatitis E viruses, human T-lymphotropic viruses, Friend spleen focus-forming viruses (SFFV), Xenotropic MuLVRelated Viruses (XMRV). In some embodiments, the pathogen is HIV. Prime vaccine

[0083] The prime vaccine comprises one or more mRNA constructs encoding one or more immunogens from the pathogen. In some embodiments, the prime vaccine comprises a conventional mRNA-based vaccine. As used herein, the term “conventional mRNA-based vaccine” refers to a mRNA vaccine construct that is not capable of self-replication when introduced into a target cell. In some embodiments, the conventional mRNA-based vaccine comprises a mRNA sequence that contains a coding sequence encoding an immunogen of interest and untranslated regions (UTRs) that flank the coding sequence at the 5’ and 3’ ends of the coding sequence. In some embodiments, the conventional mRNA-based vaccine further comprises a 5’- Cap and a 3’-poly A tail. FIG.2, shows an exemplary structure of a conventional mRNA-vaccine.

[0084] In some embodiments, the prime vaccine comprises a self-amplifying mRNA- based vaccine. As used herein, the term “self-amplifying mRNA-based vaccine” refers to a mRNA vaccine construct that is capable of self-replication when introduced into a target cell.

[0085] In some embodiments, the self-amplifying mRNA-based vaccine additionally contains viral 5′- and 3′-CSEs and the non-structure protein 1-4 (nsP1–nsP4) gene comparing to conventional mRNA. The immunogen is placed under control of the subgenomic promoter (SGP) replacing the viral structural proteins. Positive-sense alphavirus 17 WAS:164427.1genomes that have been commonly used for saRNA vaccine design include the Venezuelan equine encephalitis virus (VEE), and Semliki forest virus (SFV). Following in situ translation, the nsP1-4 proteins form an RdRP complex which recognizes flanking CSE sequences and amplifies vaccine-encoding transcripts. This results in an accumulation of the immunogen within the cell. In some embodiments, the RNA sequence further comprises a 5’- Cap and a 3’-poly A tail. FIG.3, shows an exemplary structure of a self-amplifying mRNA-construct. As a result of their self-replicative activity, self-amplifying RNA vaccines can be delivered at lower concentrations than conventional mRNA vaccines to achieve comparable immunogen expression.

[0086] In some embodiments, the pathogen is HIV-1 and the prime vaccine comprises a mRNA construct encoding a HIV-1 envelope immunogen. In some embodiments, the prime vaccine comprises mRNA construct(s) encoding one or more HIV-1 gp120, HIV-1 gp140, HIV-1 gp160, trimeric envelope glycoprotein, or modified HIV-1 gp120, gp140, HIV-1 gp160, trimeric envelope glycoprotein, wherein the boost vaccine (in any non-mRNA vaccine modality) comprises one or more HIV-1 gp120 , gp140, HIV-1 gp160, trimeric envelope glycoprotein, or modified HIV-1 gp120, gp140, HIV-1 gp160, trimeric envelope glycoprotein encoded in the prime vaccine, or wherein the boost vaccine comprises one or more HIV-1 gp120 , gp140, HIV-1 gp160, trimeric envelope glycoprotein or modified HIV-1 gp120, gp140, HIV-1 gp160, trimeric envelope glycoprotein that are not the same (such as from different viral variants) as encoded in the prime vaccine.

In some embodiments, the prime vaccine comprises mRNA construct / constructs encoding one or more HIV-1 gp120 and / or modified HIV-1 gp120, and wherein the boost vaccine (in any non-mRNA vaccine modality) comprises the one or more HIV-1 gp120 and / or modified HIV-1 gp120 encoded in the prime vaccine, or wherein the boost vaccine comprises the one or more HIV-1 gp120, or modified HIV-1 gp120 that are not the same (such as from different viral variants) as encoded in the prime vaccine.

[0088] In some embodiments, the prime vaccine comprises a mRNA construct encoding an HIV-1 envelope protein or a modified HIV-1 envelope protein. In some embodiments, the prime vaccine comprises a mRNA construct encoding a HIV-1 gp120 or a fragment thereof. In some embodiments, the prime vaccine comprises a mRNA construct encoding a HIV-1 gp120 or a modified HIV-1 gp120, wherein the HIV-1 gp120 is selected 18 WAS:164427.1from the group consisting of HIV-1 gp120-A, HIV-1 gp120-B, HIV-1 gp120-C, HIV-1 gp120-D and HIV-1 gp120-A / E.

[0089] In some embodiments, the mRNA sequence encoding HIV-1 gp120 or a modified HIV-1 gp120 is codon optimized for expression in eukaryotic host cell. Enhanced expression is useful for producing large quantities of polypeptide immunogens of the present application, and for inducing immune responses to the polypeptide immunogen in a host, e.g., a human. To enhance expression of immunogen(s), other factors concerning the efficiency with which sequences can be expressed should be considered, including the presence of features that may negatively affect expression in a cell. For example, sequences that result in RNAs predicted to have a high degree of secondary structure should be avoided. AT- and GC-rich sequences that interfere with DNA synthesis should also be avoided. Other motifs that can be detrimental to expression include internal TATA boxes, chi-sites, ribosomal entry sites, prokaryotic inhibitory motifs, cryptic splice donor and acceptor sites, and branch points. These features can be identified manually or by computer software and they can be excluded from the optimized sequences. Codon preferences for abundantly expressed proteins have been determined in a number of species, and can provide guidelines for codon substitution. Synthesis of codon-optimized sequences can be achieved by substitution of optimal codons in cloned sequences using conventional recombinant DNA methodologies known to those skilled in the art.

[0090] Generally, mRNA vaccines are produced by in vitro synthesis through an enzymatic process. Plasmid DNA (pDNA), used as an in vitro transcription template can be first constructed which usually contains the following basic elements: an upstream promoter exclusively recognized by T7, SP6 or T3 RNA polymerase; 5' UTR , codon-optimized immunogen sequence, 3' UTR, a downstream poly A-tail; and a unique cleavage site downstream of the poly A-tail. The pDNA is first linearized with the selected unique restriction site enzyme. Following linearization, in vitro transcription and capping is performed in a mixed solution of recombinant RNA polymerase (T7, T3 or SP6) and nucleoside triphosphates, plus a cap analog such as CleanCap®Reagent or ARCA (Anti- Reverse Cap Analog). Finally, when the length of the poly A tail of the template pDNA is insufficient (up to 150 bases), it can be extended by use of poly A enzyme. Further purification will remove the linearized pDNA template and other contaminants. 19 WAS:164427.1

[0108] Once the prime vaccine is delivered, the mRNA molecules are taken up into host cells, which then express the encoded immunogen thereof. Once expressed, the immunogen thereof is processed and presented in the context of self-major histocompatibility (MHC) class I and class II molecules.

[0127] In some embodiments, the vaccine composition of the present application further comprises, or is administered in combination with, one or more adjuvants. Adjuvants may be used in combination with the vaccine composition of the present application to e.g., improve stability and uptake, improve immune induction, enhance an immune response, but is not antigenic itself when administered in the absence of an antigen. Additionally, an adjuvant may decrease the dosage required to induce an effective immune response.

[0128] Exemplary adjuvants include, but are not limited to, mineral salts, complete and incomplete Freund's adjuvant, squalene based adjuvants, saponins based adjuvants, toll- like receptor (TLR) ligands, microbial derivatives, and cytokines. In some embodiments, vaccine composition of the present application comprises an adjuvant selected from the group consisting of GLA-SE, MPL, ALUM, QS-21, liposome and 3M-052.

[0129] It is especially advantageous to formulate the vaccine composition of the present application in dosage unit form for ease of administration and uniformity of dosage.

[0130] Another aspect of the present application relates to a HIV-1 vaccine formulation. In some embodiments, the HIV-1 vaccine formulation comprises: (1) a prime component comprising a mRNA construct encoding an HIV-1 env immunogen or a modified HIV-1 env immunogen, such as in the form of gp120, gp140, gp160, trimeric envelope glycoprotein or other modified env immunogens and (2) a boost component (in any non- mRNA vaccine modality) comprising the immunogen encoded in the mRNA construct or a boost component comprising the immunogen that are not the same (such as from different viral variants) as encoded in the mRNA construct, wherein the prime component and boost components are formulated for separate administration.

[0131] In some embodiments, the formulation comprises one or more other elements including: instructions for use; other reagents, e.g., a diluent, an adjuvant, devices or other materials for preparing the prime component and boost component for administration.

[0132] The present disclosure is further illustrated by the following examples that should not be construed as limiting. The contents of all references, patents, and published 26 WAS:164427.1patent applications cited throughout this application, as well as the Figures and Tables, are incorporated herein by reference. 27 WAS:164427.1EXAMPLES Example 1: Polyvalent mRNA prime-protein boost HIV-1 vaccine formulations (mRNA and protein employing same immunogens)

[0133] A heterologous prime boost regimen is administered using an mRNA vaccine as the prime vaccination to the host, and then the host is boosted by another type of vaccine (such as in the form of recombinant protein but may be in any other types of vaccines) of the same / similar immunogen(s) as included in the prime mRNA vaccine. This method is applicable against a diverse range of human and animal pathogens.

[0134] The formulations below show exemplary design of a polyvalent HIV-1 protein vaccine (boost vaccine) that comprises the same polyvalent HIV-1 gp120 as encoded by an mRNA vaccine, which is used as the prime vaccine.

[0135] The regimen is adjuvanted with GLA-SE or other adjuvants such as MPL, ALUM, QS-21, liposome, 3M-052.

[0136] A DNA prime + protein boost regimen used in HVTN 124 trial achieved robust immunogenicity including the best anti-V1V2 antibody responses by a large margin over other HVTN trials that also use prime boost regimen (FIG.4). Protein sequences analysis finds a low degree of sequence matching percentage (~70%) between prime and boost vaccines for other HVTN trials vs a 100% match in HVTN124 trial (Table 1). The immunogenicity results observed in HVTN 124 trial lend further credence to the value of matching prime–boost antigens approach. Table 1.

Claims

WHAT IS CLAIMED IS:

1. A method for immunizing a subject preventing infection by a pathogen, comprising the steps of: (1) administering to the subject an effective amount of a prime vaccine, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more prime immunogens, wherein the one or more prime immunogens are selected from the group consisting of immunogens from the pathogen and modified immunogens from the pathogen; and (2) administering to the subject an effective amount of a boost vaccine, wherein the booster vaccine comprises one or more booster immunogens, wherein at least one of the booster immunogens has an amino acid sequence identity of 75% or greater to at least one of the prime immunogens, wherein the boost vaccine is in a non-mRNA vaccine modality, and wherein the boost vaccine is administered after the administration of the prime vaccine.

2. The method of claim 1, wherein at least one of the booster immunogens has an amino acid sequence identity of 85% or greater to at least one of the prime immunogens.

3. The method of claim 1, wherein at least one of the booster immunogens has an amino acid sequence identity of 90% or greater to at least one of the prime immunogens.

4. The method of claim 1, wherein at least one of the booster immunogens has an amino acid sequence identity of 95% or greater to at least one of the prime immunogens.

5. The method of any one of claims 1 to 4, wherein boost vaccine comprises a recombinant protein.

6. The method of any one of claims 1 to 5, wherein the pathogen is HIV-1, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more HIV-1 envelop proteins and / or modified HIV-1 envelope proteins, and wherein the boost vaccine comprises the one or more HIV-1 envelope proteins and / or modified HIV-1 envelope proteins. 58 WAS:164427.

17. The method of claim 6, wherein the one or more HIV-1 envelop proteins are selected from the group consisting of gp120, gp140 and envelope proteins with optimized structural designs.

8. A method for introducing an immune response against HIV-1 in a subject, comprising the steps of: (1) administering to the subject an effective amount of a prime vaccine, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more prime immunogens, wherein the one or more prime immunogens are selected from the group consisting of HIV-1 env immunogens and modified HIV-1 env immunogens; and (2) administering to the subject an effective amount of a boost vaccine, wherein the booster vaccine comprises one or more booster immunogens, wherein at least one of the booster immunogens has an amino acid sequence identity of 75% or greater to at least one of the prime immunogens, wherein the boost vaccine is in a non-mRNA vaccine modality, and wherein the boost vaccine is administered after the administration of the prime vaccine.

9. The method of claim 8, wherein at least one of the booster immunogens has an amino acid sequence identity of 85% or greater to at least one of the prime immunogens.

10. The method of claim 8, wherein at least one of the booster immunogens has an amino acid sequence identity of 90% or greater to at least one of the prime immunogens.

11. The method of claim 8, wherein at least one of the booster immunogens has an amino acid sequence identity of 95% or greater to at least one of the prime immunogens.

12. The method of any one of claims 8 to 11, wherein the one or more HIV-1 envelop proteins are selected from the group consisting of gp120, gp140 and HIV-1 envelope proteins with optimized structural designs.

13. The method of any one of claims 8 to 12, wherein the prime vaccine comprises one or more mRNA constructs encoding one or more HIV-1 gp120 and / or modified HIV-1 gp120, and 59 WAS:164427.1wherein the boost vaccine comprises the one or more HIV-1 gp120 protein and / or modified HIV- 1 gp120 protein.

14. An mRNA-primed vaccine formulation, comprising: (1) a mRNA component comprising one or more mRNA constructs encoding one or more prime immunogens from a pathogen; and (2) a non-mRNA component comprising one or more booster immunogens, wherein at least one of the booster immunogens has an amino acid sequence identity of 75% or greater to at least one of the prime immunogens; wherein (1) and (2) are formulated for separate administration.

15. The mRNA-primed vaccine formulation of claim 14, wherein the pathogen is HIV-1.

16. The mRNA-primed vaccine formulation of claim 14 or 15, wherein the one or more prime immunogens are selected from the group consisting of HIV-1 env immunogens and modified HIV-1 env immunogens.
