The sequence listing submitted via EFS-Web is part of this specification, and its entirety is incorporated herein by reference. Background Art

[0005] Alphavirus-based self-amplifying RNA (replicons) have been used for decades as a general platform for vaccines. Two features that make replicons suitable for such platforms are: 1) high and long-term protein expression; and 2) the self-adjuvanting nature of the platform, which helps drive robust cellular, humoral, and mucosal immunity. Although these features make replicons excellent as vaccine platforms, they have the potential to hinder their performance in other areas, particularly as a platform for in vivo expression of biotherapeutics.

[0006] The use of biotherapeutics in medicine is on the rise. However, these recombinantly produced proteins are often recognized as foreign and trigger immune responses and induce anti-drug antibodies (ADA), thereby reducing the therapeutic effect of the protein. Although the factors that contribute to the development of anti-drug antibody (ADA) responses vary, the inflammatory environment in which the biologic or biotherapeutic is delivered can promote and / or enhance the ADA response. Therefore, there is a risk of promoting ADA responses and reducing the clinical efficacy of the encoded biotherapeutic from replicons that are naturally self-adjuvanting and inflammatory. The ability to downregulate the immune response to heterologous proteins expressed by replicons will reduce the risk of generating ADA and enhance the utility of replicons in expressing biotherapeutics in vivo.

[0007] It would therefore be useful to have compositions and methods that allow for administration of biotherapeutic molecules to humans or animals in a manner that reduces or eliminates the risk of eliciting an undesirable immune response. Summary of the invention

[0008] The present invention provides RNA replicons that can be used to administer heterologous molecules to humans or animals and reduce or eliminate the immune response of humans or animals to heterologous molecules. The RNA replicons have an RNA sequence (e.g., a gene of interest (GOI)) encoding a heterologous molecule (e.g., a protein or peptide), and an RNA sequence encoding the New World Alphavirus nonstructural proteins nsP1, nsP2, and nsP4; and the Alphavirus nsP3 protein macrodomain (macro domain), central domain, and hypervariable domain (HVD). The encoded hypervariable domain can have an amino acid sequence derived from the Old World Alphavirus nsP3 hypervariable domain, or can have an amino acid sequence derived from a portion of the New World Alphavirus nsP3 hypervariable domain and another portion of the Old World Alphavirus nsP3 hypervariable domain, i.e., a chimeric nsP3 hypervariable domain. It was found that when the New World Alphavirus-based replicon is modified as described herein, the immune response caused by the encoded heterologous protein or peptide is reduced or eliminated.

[0009] RNA replicons can be used to administer biotherapeutic molecules such as proteins and peptides, wherein the replicons of the invention are administered to a human or animal, the replicons encoding the biotherapeutic agent, and the encoded biotherapeutic agent (eg, a heterologous protein or peptide) is expressed in the human or animal.

The replicons also have RNA sequences encoding amino acid sequences derived from the macrodomain of the alphavirus nsP3, and RNA sequences encoding amino acid sequences derived from the central domain of the alphavirus nsP3. The RNA replicons of the present invention also have RNA sequences encoding amino acid sequences completely derived from the hypervariable domain of the Old World Alphavirus nsP3, or amino acid sequences having a portion derived from the hypervariable domain of the New World Alphavirus nsP3 and a portion derived from the hypervariable domain of the Old World Alphavirus nsP3.

[0036] The nsP1, nsP2, nsP3 and nsP4 proteins encoded by the replicon are functional or biologically active proteins. The RNA replicon of the present invention can also encode a 3' untranslated region (UTR) and a 5'UTR, which can be an alphavirus 3' and 5'UTR. The RNA replicon can also encode a control element (e.g., one or more subgenomic promoters) and a poly-A tail. The promoter, 5' and / or 3'UTR and an RNA sequence encoding a heterologous protein or peptide can be operably linked so that the replicon RNA self-amplifies when introduced into an organism, and the heterologous protein or peptide is expressed in the organism.

Therefore, in some embodiments of the replicon, the nsP3 macrodomain and the central domain may be derived from a New World Alphavirus sequence, and the HVD a) is derived from an Old World Alphavirus HVD sequence, or b) has a portion derived from an Old World Alphavirus HVD sequence and a portion derived from a New World Alphavirus HVD sequence.

[0042] In some embodiments, the N-terminal portion of the HVD may be derived from a New World nsP3 HVD sequence, and the C-terminal amino acid of the HVD may be derived from a wild-type OW alphavirus HVD amino acid sequence, e.g., at least 5 or at least 10 or at least 15 or at least 20 or at least 25 or at least 30 or at least 31 or at least 32 or at least 33 or at least 34 or at least 35 or 35-55 or 35-65 or at least 40 or at least 45 or at least 50 or at least 52 or at least 53 or at least 60 or at least 70 or at least 80 or at least 100 or at least 125 or at least 150 or at least 175. The C-terminal amino acid of the HVD may be an amino acid sequence derived from (and optionally corresponding to) an OW HVD; in any of these embodiments, the HVD may also be less than 200 or less than 175 or less than 150 or less than 125 or less than 100 or less than 80 amino acids in length. In further embodiments, the C-terminal amino acids, such as the terminal 1-5 or 5 or 5-10 or 10-12 or 10-13 or 10-15 or 15-20 amino acids, can be retained from the NW alphavirus C-terminal HVD sequence, while the remaining C-terminal amino acids can be derived from the OW alphavirus HVD as described.

[0043] In any of the embodiments described herein, the New World alphavirus can be VEEV or EEEV or WEEV or any New World alphavirus described herein or known in the art, and the Old World alphavirus can be CHIKV, SINV or SFV or any Old World virus described herein or known in the art. The New World and Old World alphaviruses can be used in the present invention in any combination, and all possible combinations and subcombinations are disclosed as fully set forth herein.

[0044] Alphavirus replicon

[0045] Alphaviruses are classified as Class IV Togaviridae. These viruses carry a positive single-stranded RNA genome, which is typically 11 kb-12 kb. The length of the alphavirus replicon of the present invention can be 11 kb-12 kb, or 10-13 kb, or 7-20 kb or 7-25 kb, and can have a 5' cap and a 3' poly-A tail, which can be an alphavirus 5' cap and a 3' poly-A tail. The 5' cap can be those known to those skilled in the art, such as a 7-methylguanylate cap, or an anti-reverse cap analog 3'-O-Me-m7G (5') ppp (5') G or another similar cap structure. They are generally enveloped viruses, spherical in shape, with a diameter of about 70 nm. They can also have an equidistant nucleocapsid. The replicon can be encoded on a single RNA. The alphavirus genome and replicon have two open reading frames (ORFs), non-structural and structural. The nonstructural portion of the genome encodes proteins nsP1-nsP4, which play a role in the transcription and replication of viral RNA, are produced as polyproteins, and are the viral replication machinery. However, the replicon may have one or two or more than two open reading frames. Any alphavirus replicon of the present invention may lack or not contain a capsid, nucleocapsid, coat protein or nucleoprotein, or may not be contained in or associated with a capsid, nucleocapsid, coat protein or nucleoprotein. The alphavirus replicon may be an RNA molecule.

[0046] The structural portion of the genome encodes the core nucleocapsid protein C, and the envelope proteins P62 and E1 that associate as heterodimers. The RNA replicons of the present invention may have any one or more of the features of an alphavirus. In some embodiments, the RNA replicons of the present invention lack sequences encoding alphavirus structural proteins; or do not encode alphavirus (or, optionally, any other) structural proteins. In some embodiments, the RNA replicons of the present invention do not encode any one or more of proteins C, P62, 6K, and E1, including all combinations and subcombinations, as fully shown herein. In some embodiments, the RNA replicons of the present invention do not encode any one of proteins C, P62, 6K, and E1.

[0047] The geographic separation of the alphavirus family may be a factor in the evolution of these viruses and their adaptation to their unique environment. The circulating alphavirus serum complex can be further classified as Old World or New World alphaviruses. Old World and New World alphaviruses have sequences that can be used in the present invention as described herein. New World alphaviruses include any New World alphavirus, such as Eastern Equine Encephalitis Virus (EEEV), Venezuelan Equine Encephalitis Virus (VEEV), Western Equine Encephalitis Virus (WEEV), Fort Morgan (FMV), Highland J Virus (HJV), Buggy Creek Virus (BCRV), Mucambo Virus (MUCV) and Pixuna Virus (PIXV). Old World alphaviruses include any Old World alphavirus, such as Sindbis virus (SINV), Semliki Forest virus (SFV), Chikungunya virus (CHIKV), Bebaru virus (BEBV), O'Nyong Nyong virus (ONNV), Ross River virus (RRV), Sao Mountain virus (SAGV), Geta virus (GETV), Middelburg virus (MIDV), Ndum virus (NDUV), Barmah Forest virus (BFV), Mayaro virus (MAYV), Aura virus (AURA), Una virus, Whataroa virus, Babank virus, and Kyzylagach virus. New World and Old World viruses and their sequences can be used in any combination or subcombination in the RNA replicons of the present invention, and are disclosed in all possible combinations and subcombinations, as fully set forth herein.

[0048] The RNA replicons of the present invention may be derived from alphavirus genomes, meaning that they have some structural features of alphavirus genomes, or are similar to them. The RNA replicons of the present invention may be modified alphavirus genomes. In some embodiments of the replicons disclosed herein, one or more sequences of the replicon may be provided "in trans", i.e., the sequences of the replicon are provided on more than one RNA molecule. In other embodiments, all sequences of the replicon are present on a single RNA molecule, which may also be administered to a mammal to be treated as described herein.

[0049] From

[0050] The RNA replicons of the invention may comprise an RNA sequence (or an amino acid sequence encoded thereby) from a wild-type New World or Old World alphavirus genome. Any RNA replicons of the invention disclosed herein may comprise RNA sequences "derived from" or "based on" wild-type alphavirus genome sequences, meaning that they have at least 60% or at least 65% or at least 68% or at least 70% or at least 80% or at least 85% or at least 90% or at least 95% or at least 97% or at least 98% or at least 99% or 100% or 80-99% or 90-100% or 95-99% or 95-100% or 97-99% or 98-99% sequence identity with an RNA sequence (which may be a corresponding RNA sequence) from a wild-type RNA alphavirus genome, which may be a New World or Old World alphavirus genome. Any nucleic acid or amino acid sequence disclosed herein may be functional or biologically active and operably linked to another sequence required for self-replication of the alphavirus or replicon. A molecule is functional or biologically active if it exhibits at least 50% of the same activity of its native (or wild type) corresponding molecule, but a functional molecule may also exhibit at least 60% or at least 70% or at least 90% or at least 95% or 100% of the same activity of its native (or wild type) corresponding molecule. The RNA replicons may also encode amino acid sequences derived from or based on wild type alphavirus amino acid sequences, meaning that they have at least 60% or at least 65% or at least 68% or at least 70% or at least 80% at least 70% or at least 80% or at least 90% or at least 95% or at least 97% or at least 98% or at least 99% or 100% or 80-99% or 90-100% or 95-99% or 95-100% or 97-99% or 98-99% sequence identity with the amino acid sequence encoded by the wild type RNA alphavirus genome (which may be the corresponding sequence), the wild type RNA alphavirus genome may be a New World or Old World alphavirus genome. Sequences derived from other sequences may be up to 5% longer or shorter than the original sequence, or up to 10% or up to 20% or up to 30%. In any embodiment, for any nucleotide sequence encoding a G3BP or FXR binding site thereon (or an amino acid sequence having a G3BP or FXR binding site thereon), the sequence identity may be at least 95%, or at least 97%, or at least 98%, or at least 99%, or 100%. These sequences may also be up to 5%, or up to 10%, or up to 20%, or up to 30% longer or shorter than the original sequence.

[0051] For example, in some embodiments, the RNA sequence encoding any one or more of the nsP1, nsP2, nsP3 macrodomain, nsP3 central domain, nsP3 hypervariable domain, and / or nsP4 proteins can be derived from a corresponding wild-type alphavirus sequence. A "corresponding" sequence can be an analogous sequence in another type of alphavirus. Corresponding sequences are disclosed herein and can also be determined by sequence alignment tools known to those skilled in the art (e.g., Clustal Omega). Figure 6 A sequence alignment is shown, which illustrates corresponding sequences of nsP3 proteins from representative members of the Old World and New World alphaviruses, obtained using Clustal Omega. However, other sequence alignment tools acceptable to those of ordinary skill in the art may also be used. Programs useful for performing sequence alignments may also be found in Molecular Systems Biology (2011) 7, 539. Thus, the nsP1, nsP2, nsP3, nsP4 sequences from the New World alphaviruses "correspond to" the nsP1, nsP2, nsP3, nsP4 sequences from the Old World alphaviruses, respectively. Sequences may also be corresponding sequences. The corresponding amino acid sequence can be at least 5 or at least 10 or at least 15 or at least 20 or at least 25 or at least 30 or at least 52 or at least 53 or at least 75 or at least 100 or at least 125 or at least 150 or at least 175 or at least 200 amino acids and is up to 5% or up to 10% or up to 20% or up to 30% longer or shorter than the original sequence; the corresponding nucleic acid sequence can be at least 15 or at least 30 or at least 45 or at least 60 or at least 75 or at least 90 or at least 156 or at least 159 or at least 225 or at least 300 or at least 375 or at least 450 or at least 525 or at least 600 nucleotides. Such sequences can be up to 5% or up to 10% or up to 20% or up to 30% longer or shorter than the original sequence.

[0052] In some embodiments of the replicon, each of the nsP1, nsP2, and nsP4 sequences may be derived from or based on a New World Alphavirus genome. In some embodiments, an RNA replicon derived from or based on a wild-type New World Alphavirus genome may contain at least one RNA sequence that is not derived from a wild-type New World Alphavirus genome (in addition to at least one heterologous protein or peptide), which may be a sequence of nsP3, or a sequence of a central and / or macrodomain of nsP3, or at least a portion of HVD. In some embodiments, an RNA replicon derived from a New World Alphavirus genome may have an RNA sequence encoding nsP3 or a domain of nsP3 or a portion of a domain of nsP3, which is replaced by a corresponding sequence from a wild-type Old World Alphavirus genome. When referring to the entire replicon as "derived from" or "based on", the sequence of the RNA encoding at least one heterologous protein or peptide is not counted, and optionally, the sequence encoding the nsP3 protein, or any one or more macrodomains, central domains, and / or HVD domains of nsP3 in any combination or subcombination may also be excluded.

[0053] The term "RNA replicon" refers to RNA that contains all the genetic information required to direct its self-amplification or self-replication in a permissive cell, which can be a human, mammal or animal cell. The RNA replicon 1) encodes an RNA-dependent RNA polymerase that can interact with viral or host cell-derived proteins, nucleic acids or ribonucleoproteins to catalyze the RNA amplification process. Non-structural proteins include nsP1, nsP2, nsP3, nsP4; and 2) contain cis-acting RNA sequences required for the replication and transcription of genomic and subgenomic RNAs, such as 3' and 5'UTRs (alphavirus nucleotide sequences for non-structural protein-mediated amplification), and / or subgenomic promoters. These sequences can bind to self-encoded proteins or non-self-encoded cell-derived proteins, nucleic acids or ribonucleoproteins or complexes between any of these components during the replication process. In some embodiments, the modified RNA replicon molecule generally comprises the following ordered elements: a 5' viral RNA sequence required for cis replication (e.g., 5'UTR and 5'CSE), a sequence encoding a biologically active nonstructural protein (e.g., nsP1234), a promoter for transcribing subgenomic RNA, a 3' viral sequence required for cis replication (e.g., 3'UTR) and a polyadenylic acid tract, and optionally, a sequence (or two or more sequences) encoding a heterologous protein or peptide after or under the control of the subgenomic promoter. In addition, the term RNA replicon can refer to a positive (or information-sense) molecule, and the length of the RNA replicon can be different from that of any known, naturally occurring RNA virus. In any embodiment of the present disclosure, the RNA replicon may lack (or contain) at least one (or all) sequence of structural viral proteins (e.g., nucleocapsid protein C, and envelope proteins P62, 6K, and E1). In these embodiments, the sequence encoding one or more structural genes may be replaced by one or more heterologous sequences, for example, a coding sequence of at least one heterologous protein or peptide (or other gene of interest (GOI)).

[0054] In various embodiments, the RNA replicon disclosed herein can be an engineered, synthetic or recombinant RNA replicon. As used herein, the term recombinant means any molecule (e.g., DNA, RNA, etc.) that is obtained or indirectly produced by artificial manipulation of polynucleotides. As a non-limiting example, cDNA is a recombinant DNA molecule, such as any nucleic acid molecule produced by an in vitro polymerase reaction, or connected to a linker or integrated into a vector (e.g., a cloning vector or an expression vector). As a non-limiting example, a recombinant RNA replicon can be one or more of the following: 1) synthesized or modified in vitro, for example, using chemical or enzymatic techniques (e.g., by using chemical nucleic acid synthesis, or by using enzymes for replication, polymerization, exonucleolytic digestion, endonucleolytic digestion, connection, reverse transcription, transcription, base modification (including, for example, methylation) or recombination (including homologous and site-specific recombination) of nucleic acid molecules); 2) nucleotide sequences that are not connected (conjoined) in nature; 3) engineered using molecular cloning techniques, so that it lacks one or more nucleotides relative to a naturally occurring nucleotide sequence; and 4) operated using molecular cloning techniques, so that it has one or more sequence changes or rearrangements relative to a naturally occurring nucleotide sequence.

[0055] As used herein, the term "percent identity" or "homology" or "shared sequence identity" or "percent (%) sequence identity" with respect to nucleic acid or polypeptide sequences is defined as the percentage of nucleotide or amino acid residues in a candidate sequence that are identical to a known polypeptide, after aligning the sequences for maximum percent identity and introducing gaps (if necessary) to achieve maximum percent homology. N-terminal or C-terminal insertions or deletions should not be construed as affecting homology, and internal deletions of less than about 30, less than about 20, or less than about 10 or less than 5 amino acid residues and / or insertions in a polypeptide sequence should not be construed as affecting homology. Homology or identity at the nucleotide or amino acid sequence level can be determined by BLAST (Basic Local Alignment Search Tool) analysis using the algorithm employed by the programs blastp, blastn, blastx, tblastn and tblastx, which are customized for sequence similarity searches. The BLAST program uses an approach that first considers similar segments (with and without gaps) between the query sequence and the database sequence, then evaluates the statistical significance of all matches identified, and finally summarizes only those matches that meet a preselected threshold of significance. For discussion of basic issues in similarity searches of sequence databases, see Altschul (1994), Nature Genetics 6, 119-129. Histograms, descriptions, comparisons, expectations (i.e., statistical significance thresholds for reporting and database sequence matching), cutoffs, matrices, and filters (low complexity) can be in default settings. The default scoring matrix used by Blastp, blastx, tblastn, and tblastx is the BLOSUM62 matrix (Henikoff (1992), Proc. Natl. Acad. Sci. USA 89, 10915-10919), which is recommended for query sequences (nucleotide bases or amino acids) of more than 85 lengths.

[0056] For blastn designed for comparison of nucleotide sequences, the scoring matrix is ​​established by the ratio of M (i.e., the reward score for a pair of matching residues) to N (i.e., the penalty score for mismatching residues), where the default values ​​for M and N can be +5 and -4, respectively. The four blastn parameters can be adjusted as follows: Q = 10 (gap creation penalty); R = 10 (gap extension penalty); wink = 1 (generate word hits at each winkth position along the query); and gapw = 16 (sets the window width in which gap alignments are generated). The equivalent Blastp parameter settings for amino acid sequence comparisons can be: Q = 9; R = 2; wink = 1; and gapw = 32. The sequences available in the GCG software package version 10.0 The comparison may use the DNA parameters GAP=50 (gap creation penalty) and LEN=3 (gap extension penalty), and the equivalent settings in a protein comparison may be GAP=8 and LEN=2.

[0057] In the nucleic acids or polypeptides disclosed herein, e.g., sequences of nsP1, nsP2, nsP3, nsP3 macrodomain, nsP3 central domain, nsP3 hypervariable domain, nsP4, RdRp, P1234, sequences believed to be based on or derived from the original sequences are also disclosed. Thus disclosed sequences include polypeptide sequences having at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, or at least 85%, such as at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99% or 100% or 85-99% or 85-95% or 90-99% or 95-99% or 97-99% or 98-99% sequence identity to the full length polypeptide sequences of any polypeptide sequences described herein, such as SEQ ID NO: 1-29 (and nucleotide sequences encoding any of SEQ ID NO: 1-29), and fragments thereof. Also disclosed are fragments or portions of any sequence disclosed herein. A fragment or portion of a sequence may include at least 5, or at least 7, or at least 10, or at least 20, or at least 30, at least 50, at least 75, at least 100, at least 125, 150 or more, or 5-10, or 10-12, or 10-15, or 15-20, or 20-40, or 20-50, or 30-50, or 30-75, or 30-100 amino acid residues of the entire sequence. The invention also discloses a sequence of at least 100 or at least 200 or at least 300 or at least 400 or at least 500 or at least 600 or at least 700 or at least 800 or at least 900 or at least 1000 or 100-200 or 100-500 or 100-1000 or 500-1000 amino acid residues (or nucleic acids encoding such fragments), or any of SEQ ID NOs: 1-29 or any fragment disclosed herein, but any of these amounts but less than 500 or less than 700 or less than 1000 or less than 2000 consecutive amino acids, or nucleic acids encoding such fragments. Variants of such sequences are also disclosed, for example, wherein at least one or two or three or four or five amino acid residues have been inserted into the N- and / or C-terminus and / or within the disclosed sequences (which include insertions and substitutions), as well as nucleic acid sequences encoding such variants.Variants contemplated may additionally or alternatively include those comprising predetermined mutations by, for example, homologous recombination or site-directed or PCR mutagenesis, and corresponding polypeptides or nucleic acids of other species, including but not limited to those described herein, alleles or other naturally occurring variants of polypeptides or nucleic acid families comprising insertions and substitutions; and / or derivatives in which the polypeptide has been covalently modified by substitution, chemical, enzymatic or other suitable means with a portion (e.g., a detectable portion such as an enzyme) other than the naturally occurring amino acids containing insertions and substitutions. The nucleic acid sequences described herein may be RNA sequences.

[0058] Any component or sequence of the RNA replicon can be operably connected to any other component or sequence. In order to express at least one heterologous protein or peptide (or biotherapeutic agent) in a host cell or the organism for treatment and / or for the ability of the replicon to replicate itself, the component or sequence of the RNA replicon can be operably connected. The term "operably connected" means a functional connection between two or more sequences, and the sequence is configured to exercise their common functions. Therefore, when there is an appropriate enzyme, a promoter or UTR operably connected to a coding sequence can affect the transcription and expression of the coding sequence. The promoter need not be adjacent to the coding sequence, as long as it plays the function of guiding the expression of the coding sequence. Therefore, the operably connected between the RNA sequence encoding a heterologous protein or peptide and a regulatory sequence (for example, a promoter or UTR) is a functional connection that allows the expression of the polynucleotide of interest. Operably connected can also refer to other sequences encoded in the sequence of a connection sequence such as encoding RdRp (for example nsP4), nsP1-4, UTR, a promoter, and an RNA replicon, so that they enable transcription and translation of biotherapeutic molecules and / or replication replicons. A UTR may be operably linked by providing sequences and spacing necessary for ribosomal recognition and translation of the other coding sequence.

[0059] G3BP and FXR

[0060] G3BP (Ras-GTPase-activating protein (Src-homology 3 (SH3) domain)-binding protein, Ras-GTPase-activating protein (Src-homology 3 (SH3) domain)-binding protein) and FXR (fragile X family protein) are both RNA binding proteins that self-assemble to form ribonucleoprotein complexes (RNPs). Both bind to the HVD domain. The RNP complex formed by G3BP and FXR performs different functions within the cell. For example, G3BP is essential for the nucleation and formation of stress granules in immune responses. The function of stress granules is to sequester and shut down mRNA translation and regulate the induction and secretion of type I interferons and other cytokines. Together, these activities enhance the antiviral state within the cell and promote adaptive immune responses. On the other hand, FXR family proteins are not thought to play a role in innate immunity, but they associate with polyribosomes and form RNA transport granules in neurons. Figure 7 Regions on various alphavirus nsP3 HVDs where these RNA binding proteins bind to alphavirus sequences are indicated.

[0061] Nonstructural proteins

[0062] The alphavirus genome encodes the nonstructural proteins nsP1, nsP2, nsP3, and nsP4, which are produced as a single polyprotein precursor, sometimes referred to as P1234 (or nsP1-4 or nsP1234), and are cleaved into mature proteins by proteolytic processing. nsP1 can be about 60 kDa in size and can have methyltransferase activity and participate in the viral capping reaction. nsP2 is about 90 kDa in size and can have helicase and protease activities, while nsP3 is about 60 kDa and contains three domains: a macrodomain, a central (or alphavirus-specific) domain, and a hypervariable domain (HVD) (see Figure 6 ). nsP4 is approximately 70 kDa in size and contains the core RNA-dependent RNA polymerase (RdRp) catalytic domain. Following infection, the alphavirus genomic RNA is translated to produce the P1234 polyprotein, which is cleaved into individual proteins.

[0063] nsP3

[0064] The alphavirus nsP3 protein contains three domains: a) a macrodomain, b) a central (or α) domain, and c) a hypervariable domain (HVD). The corresponding amino acid sequences of the three domains of some representative members of the Old World and New World alphaviruses are given in Figure 6In various embodiments, the replicon of the invention has an RNA sequence encoding a nsP3 macrodomain derived from a wild-type alphavirus nsP3 and a nsP3 central domain derived from a wild-type alphavirus nsP3. In various embodiments, the macrodomain and the central domain can both be derived from a New World wild-type alphavirus nsP3, or can both be derived from an Old World wild-type alphavirus nsP3 protein. In some embodiments, the macrodomain can be derived from a New World wild-type alphavirus macrodomain, and the central domain can be derived from an Old World wild-type alphavirus central domain, or vice versa. The various domains can be any sequence described herein.

[0065] Hypervariable domain (HVD)

[0066] In some embodiments, the replicon can have a New World alphavirus HVD in which the sequence C-terminally flanking the amino acids beginning with the FXR binding site can be deleted and replaced with a replacement sequence of an Old World wild-type alphavirus HVD sequence, or a portion thereof. Old World alphavirus replacement sequences are described herein. Thus, when the New World alphavirus is VEEV, those amino acids C-terminally flanking amino acid 478 of nsP3 can be deleted; when the New World alphavirus is EEEV, those amino acids C-terminally flanking amino acid 531 of nsP3 can be deleted; and when the New World alphavirus is WEEV, those amino acids C-terminally flanking amino acid 504 of nsP3 can be deleted (see Figure 7 ). In any of these embodiments, the replacement sequence may be substituted as described herein. As further described herein, a portion of the C-terminal amino acids of the New World alphavirus HVD may still remain on the C-terminal side of the Old World sequence.

[0067] In some embodiments, at least a portion of the sequence encoding the FXR binding site in the New World Alphavirus can be deleted and replaced with a replacement sequence described herein. Thus, when the New World Alphavirus is VEEV, amino acids 478-517 or 478-545 of nsP3 can be deleted and replaced with a replacement sequence of an Old World Alphavirus. Or when the New World Alphavirus is VEEV, at least one of the repeats present between amino acids 478-545 of nsP3 can be deleted and optionally replaced with an Old World Alphavirus replacement sequence. When the New World Alphavirus is EEEV, amino acids 531-547 of nsP3 can be deleted and replaced with an Old World replacement sequence. When the New World Alphavirus is WEEV, amino acids 504-520 of nsP3 can be deleted and replaced with an Old World replacement sequence. In other embodiments, the entire sequence encoding the FXR binding site can be deleted, or at least 50% or at least 70% or at least 80% or at least 90% of the FXR binding site can be deleted and optionally replaced with a replacement sequence. In any embodiment, the sequence shown can be deleted and no replacement sequence inserted.

[0068] The Old World Alphavirus replacement sequence can comprise an amino acid fragment having one or more G3BP binding sites or at least a portion of a G3BP binding site. Thus, the replacement sequence can be FGDF (SEQ ID NO: 18) or FGSF (SEQ ID NO: 19). The replacement sequence can also be derived from at least a portion of a wild-type nsP3 hypervariable domain of an Old World Alphavirus. Other examples of Old World Alphavirus replacement sequences are described below. The Old World Alphavirus replacement sequence can be used in a replicon having a sequence of any New World Alphavirus HVD sequence described herein. In any embodiment, the New World Alphavirus can be VEEV, EEEV, WEEV, or any New World Alphavirus described herein.

[0069] When the Old World alphavirus is CHIKV, the replacement sequence may be amino acids 479-582 or 479-500 or 479-500 of CHIKV nsP3.

[0070] When the Old World alphavirus is SINV, the replacement sequence may be a sequence comprising amino acids 490-493 or 513-516 or 490-516 of SINV nsP3.

[0071] When the Old World alphavirus is SFV, the replacement sequence may be a sequence comprising amino acids 451-471 or 451-454 or 468-471 of SFV nsP3.

[0072] When the Old World alphavirus is MAYV, the replacement sequence may be a sequence comprising amino acids 470-473 of MAYV nsP3.

[0073] When the Old World alphavirus is RRV, the replacement sequence may be a sequence comprising amino acids 412-426 or 512-515 or 523-526 of RRV nsP3.

[0074] When the Old World alphavirus is ONNV, the replacement sequence may be a sequence comprising amino acids 519-540 or 519-522 or 537-540 of ONNV nsP3.

[0075] When the Old World alphavirus is BFV, the replacement sequence may be a sequence comprising amino acids 429-450 or 429-432 or 447-450 of BFV nsP3.

[0076] The New World and Old World alphaviruses can be any alphavirus described herein, and can be combined in any possible combination or subcombination, all of which are disclosed as fully set forth herein.

[0077] The alphavirus genome encodes a core RNA-dependent RNA polymerase in nsP4. Cleavage of the polyprotein can occur at the nsP2 / 3 junction, affecting the RNA template used during genome replication. After cleavage, nsP3 can generate a ring structure around nsP2, and the two proteins have a substantial interface. Therefore, it may be useful to retain sequences around the junction of nsP2 / 3 and / or nsP3 / 4.

[0078] Thus, in some embodiments, the macro and / or central and / or HVD domains of the nsP3 protein can have a C-terminal and / or N-terminal portion (as described herein) that is an amino acid sequence derived from a New World alphavirus, while the remainder of the domain is derived from an Old World alphavirus sequence. For example, the macro and / or central and / or HVD domains can have a sequence derived from the corresponding Old World alphavirus domain, but have the first 4 or 5 or 6 or 4-6 or 6-8 or 6-10 amino acids at the N-terminus and / or C-terminus of nsP3 derived from a New World alphavirus sequence (which can be a New World alphavirus from which nsP1, nsP2, and nsP4 are derived). Thus, the replicon may have an RNA sequence as described herein, the RNA sequence encoding an amino acid sequence derived from the Old World Alphavirus nsP3 macro and / or central and / or HVD domain, and the first 1-3 or 1-4 or 1-5 or 1-6 or 1-7 or 1-8 amino acids on the N-terminal and / or C-terminal side of the domain are derived from the New World Alphavirus domain, or may have one or two or three substitutions thereon. As used herein, the terms "C-terminal" and "N-terminal" do not refer to the actual terminus, but rather to the point where the polyprotein (e.g., P1234) is split into separate polypeptides (e.g., nsP1, nsP2, nsP3, and nsP4). The sequence encoding the nsP is characterized by a stop codon, and transcription is usually terminated at this point. However, when the stop codon is treated as a read-through stop codon, the terminus may be the " / " indicated in SEQ ID NOs: 12-17, which may represent the N-terminus and / or C-terminus of the nsP. The linking sequence can be those 1-6 amino acids on either side of the terminus, for example on the nsP3 side. These embodiments allow nsP3 sequences derived from old world sequences to still retain the links between nsP2 / nsP3 and between nsP3 / nsP4. The retention of these links can allow the use of new world alphavirus enzymes to cut the P1234 protein link. In some embodiments, the penultimate glycine is retained in the link. The old world alphavirus can be any of those described herein. For example, when the new world alphavirus is VEEV, the nsP2 / nsP3 sequence can be LHEAGC / APSY (SEQ ID NO: 12), the slash (" / ") represents the boundary between nsP2 and nsP3, and the penultimate G is retained, while the remaining amino acids in the nsP2 / nsP3 link are varied as described herein. In the case of the nsP3 / nsP4 link of VEEV, the sequence can be RFDAGA / YIFS (SEQ ID NO: 13), again retaining the penultimate glycine, and the remaining nsP3 amino acids are varied as described herein. These sequences may also be followed by a stop codon (TGA), which may sometimes be considered a read-through stop codon as described above.When the New World Alphavirus is EEEV, the nsP2 / nsP3 sequence can be QHEAGR / APAY (SEQ ID NO: 14), with the slash (" / ") representing the boundary between nsP2 and nsP3, and the penultimate G is retained, while the remaining amino acids in the nsP2 / nsP3 junction are varied as described herein. In the case of the nsP3 / nsP4 junction of EEEV, the sequence can be RYEAGA / YIFS (SEQ ID NO: 15), again retaining the penultimate glycine, and the remaining nsP3 amino acids are varied as described herein. These sequences can also be followed by a read-through stop codon (TGA), as above. When the New World Alphavirus is WEEV, the nsP2 / nsP3 sequence can be RYEAGR / APAY (SEQ ID NO: 16), with the slash (" / ") representing the terminus or end of nsP2 (and the junction between nsP2 and nsP3), and the penultimate G is retained, while the remaining amino acids in the nsP2 / nsP3 junction are varied as described herein. In the case of the nsP3 / nsP4 connection of WEEV, the sequence can be RYEAGA / YIFS (SEQ ID NO: 17), again retaining the penultimate glycine, and the remaining nsP3 amino acids are varied as described herein. These sequences can also be followed by a read-through stop codon (TGA), as explained herein. Any of these sequences (SEQ ID NOs: 12-17) can also contain one or two or three substitutions on the N-terminal and / or C-terminal side.

[0079] Repeating motif

[0080] Alphaviruses may contain conserved sequence elements (CSEs), which are similar or identical sequences in nucleic acid sequences or polypeptides across species. CSEs may be present in the HVD of New World or Old World alphavirus nsP3 and are known in the art.

[0081] The Old World Alphavirus may also comprise a FGDF (SEQ ID NO: 18) or FGSF (SEQ ID NO: 19) amino acid motif, which may be repeated in the sequence to form a repetitive sequence or repetitive motif. In any embodiment of the RNA replicon of the invention, the HVD of the Old World Alphavirus may comprise FGDF / FGDF (SEQ ID NO: 20) repetitions, or FGSF / FGSF (SEQ ID NO: 21) repetitions, or FGDF / FGSF (SEQ ID NO: 22) repetitions, or FGSF / FGDF (SEQ ID NO: 23) repetitions. In all embodiments where repetitions are present, the two repetitive motifs may be separated by one or more amino acid residues. In various embodiments, the two repetitive motifs may be separated by 5 or 6 or 7 or 8 or 9 or 10 or at least 10 or 11 or 12 or 13 or 14 or 15 or 16 or 17 or 18 or 19 or 20 or 21 or 22 or 23 or 24 or 25 amino acid residues, or more than 25 amino acid residues, which in one embodiment may be random amino acids. In one embodiment, the motif or repeat motif is separated by at least 10 and no more than 25 amino acids, which may also be random amino acids. In various embodiments, two repeat motifs may be separated by NEGEIESLSSELLT (SEQ ID NO: 6), SDGEIDELSRRVTTESEPVL (SEQ ID NO: 7) or DEHEVDALASGIT (SEQ ID NO: 8) or a sequence derived from any of them, which may have the same length; thus, a repeat motif separated by SEQ ID NO: 6, 7 or 8 is disclosed, which has 1) FGDF (SEQ ID NO: 18) motifs at both ends; 2) FGSF (SEQ ID NO: 19) motifs at both ends; 3) FGDF (SEQ ID NO: 18) motifs at the 3' or 5' end and FGSF (SEQ ID NO: 19) motifs at the opposite end.

[0082] Untranslated region

[0083] Any replicon of the present invention may also include 5' and 3' untranslated regions (UTRs). UTRs may be wild-type New World or Old World alphavirus UTR sequences, or sequences derived from any of them. In various embodiments, 5'UTRs may have any suitable length, such as about 60nt or 50-70nt or 40-80nt. In some embodiments, 5'UTRs may also have a conservative primary or secondary structure (e.g., one or more stem-loops), and may participate in the replication of alphavirus or replicon RNA. In some embodiments, 3'UTRs may be up to several hundred nucleotides, such as 50-900 or 100-900 or 50-800 or 100-700 or 200nt–700nt. '3UTRs may also have a secondary structure, such as a step loop, and may be followed by a polyadenylic acid tract or a poly-A tail. In any embodiment of the present invention, 5' and 3' untranslated regions may be operably linked to any other sequence encoded by the replicon. The UTR can be operably linked to a promoter and / or a sequence encoding a heterologous protein or peptide by providing sequences and spacing required for recognition and translation of the other encoded sequences.

[0084] In one embodiment, the RNA replicon of the present invention can have an RNA sequence encoding a heterologous protein or peptide (e.g., a monoclonal antibody or a biotherapeutic protein or peptide), an RNA sequence encoding an amino acid sequence derived from the wild-type New World Alphavirus nsP1, nsP2, and nsP4 protein sequences, and 5' and 3' UTR sequences (for non-structural protein-mediated amplification). The RNA replicon can also have a 5' cap and a polyadenylic acid (or poly-A) tail. The RNA replicon can also encode an amino acid sequence derived from the New World Alphavirus macrodomain, an amino acid sequence derived from the New World Alphavirus central domain, and an amino acid sequence derived from the Old World Alphavirus hypervariable domain. In an alternative embodiment, the RNA replicon can encode a portion having an amino acid sequence derived from the New World hypervariable domain, and another portion having an amino acid sequence derived from the Old World Alphavirus hypervariable domain, as described herein.

[0085] The immunogenicity of a heterologous protein or peptide can be determined by a number of assays known to those of ordinary skill in the art, such as by immunostaining of intracellular cytokines or secreted cytokines of epitope-specific T-cell populations, or by quantifying the frequency and total number of epitope-specific T-cells and characterizing their differentiation and activation states, e.g., short-term effector and memory precursor effector CD8+ T-cells. Immunogenicity can also be determined by measuring antibody-mediated immune responses, such as antibody production by measuring serum IgA or IgG titers.

[0086] Heterologous proteins and peptides

[0087] The RNA replicons of the present invention include RNA sequences encoding at least one protein or peptide that is heterologous to the alphavirus and may also (but not necessarily) be heterologous to the human, mammal or animal expressing the RNA sequence in vivo. In any embodiment, the replicon may have RNA sequences encoding two or three or more heterologous proteins or peptides. In various embodiments, the heterologous protein or peptide is a biotherapeutic molecule as described herein. Although there is a risk of eliciting an anti-drug antibody immune response when administering a biotherapeutic molecule to a human, mammal or animal, the present invention allows the administration of the replicon to the human, mammal or animal body and allows the expression of the biotherapeutic agent in the human, mammal or animal body, while generating a substantially reduced immune response or no immune response from the cells of the human, mammal or animal that receive the replicon and express the biotherapeutic molecule. In any embodiment, the sequence encoding the heterologous protein or peptide may be operably linked to one or more other sequences of the replicon (e.g., a promoter or 5' or 3' UTR sequence) and may be under the control of a subgenomic promoter so that the heterologous protein or peptide is expressed in a human, mammal or animal.

[0088] The heterologous protein or peptide can be any protein or peptide, examples of which include cytokines, growth factors, immunoglobulins, monoclonal antibodies (including Fab antigen binding fragments, Fc fusion proteins), hormones, interferons, interleukins, regulatory peptides and proteins. Specific examples of monoclonal antibodies that can be heterologous proteins include raxibacumab, tocilizumab, brentuzimab vedotin, factor IX Fc fusion protein, rilonacept, ofatumumab, bevacizumab, belimumab, certolizumab pegol, ramucirumab, factor VIII Fc fusion protein, etanercept, vedolizumab, cetuximab, aflibercept, obinutuzumab, trastuzumab, adalimumab, canakinumab, infliximab, ado-trastuzumabemtansine, pembrolizumab, alemtuzumab, ranibizumab, romiplostim, belatacept, abatacept, pertuzumab pertuzumab, denosumab, infliximab, catumaxomab, infliximab, abciximab, rituximab, golimumab, basiliximab, eculizamab, ustekinumab, siltuximab, palivizumab, natalizumab, panitumumab, denosumab, omalizumab, ipilimumab, zivaflibercept, and ibritumomab tiuxetan.In other embodiments, the heterologous protein or peptide can be an endothelial growth factor (e.g., vascular endothelial growth factor, a hormone (e.g., insulin, relaxin), an exon skipping oligonucleotide, a morpholino oligomer, a morpholino antisense oligomer, or an RNA encoding a tumor specific antigen. In some embodiments, the heterologous protein or peptide can be encoded by an RNA sequence of up to 5 kb, or up to 6 kb, or up to 7 kb, or up to 8 kb, or up to 9 kb, or up to 10 kb, or up to 11 kb, or up to 12 kb. The heterologous protein can also be a single chain antibody molecule.

[0089] The alphavirus replicons of the present invention may also have a subgenomic promoter for the expression of heterologous proteins or peptides. As used herein, the term "subgenomic promoter" refers to a promoter of a subgenomic mRNA of a viral nucleic acid. As used herein, an "alphavirus subgenomic promoter" is a promoter originally defined in a wild-type alphavirus genome that directs the transcription of a subgenomic messenger RNA as part of the alphavirus replication process.

[0090] When used with respect to polynucleotides, genes, nucleic acids, polypeptides, proteins or enzymes, the term "heterologous" refers to polynucleotides, genes, nucleic acids, polypeptides, proteins or enzymes that are not derived from a host species. For example, "heterologous genes" or "heterologous nucleic acid sequences" as used herein refer to genes or nucleic acid sequences from species different from the host organism species introduced therein. Heterologous sequences can also be synthetic, rather than being derived from an organism or not found in nature. When referring to gene regulatory sequences or auxiliary nucleic acid sequences (e.g., 5' untranslated regions, 3' untranslated regions, poly A addition sequences, intron sequences, splice sites, ribosome binding sites, internal ribosome entry sequences, genome homology regions, recombination sites, etc.) or nucleic acid sequences encoding protein domains or protein localization sequences for manipulating gene sequence expression, "heterologous" means that the sequence of regulating or auxiliary sequences or encoding protein domains or localization sequences is from a different source of genes in parallel with the nucleic acid sequences of genome, chromosome or episomes (episome) and regulating or auxiliary nucleic acid sequences or encoding protein domains or localization sequences. Thus, a promoter that is operably linked to a gene to which it is not operably linked in its natural state (e.g., in the genome of a non-genetically engineered organism) is referred to herein as a "heterologous promoter," even though the promoter may be derived from the same species (or, in some cases, the same organism) as the gene to which it is linked. Similarly, "heterologous" when referring to a protein localization sequence or protein domain of an engineered protein means that the localization sequence or protein domain is derived from a different protein than the protein into which it is incorporated by genetic engineering.

[0091] As used herein, the term "recombinant" or "engineered" nucleic acid molecule refers to a nucleic acid molecule that has been altered by human intervention. As a non-limiting example, cDNA is a recombinant DNA molecule, such as any nucleic acid molecule produced by an in vitro polymerase reaction, or to which a linker has been attached or has been integrated into a vector (such as a cloning vector or an expression vector or a replicon). As a non-limiting example, a recombinant nucleic acid molecule: 1) has been synthesized or modified in vitro, for example, using chemical or enzymatic techniques of nucleic acid molecules (e.g., by using chemical nucleic acid synthesis, or by using enzymes, the enzymes are used for replication, polymerization, exonucleolytic digestion, endonucleolytic digestion, ligation, reverse transcription, transcription, base modification (including, for example, methylation) or recombination (including homologous and site-specific recombination)); 2) includes ligated nucleotide sequences that are not connected in nature; 3) has been engineered using molecular cloning techniques so that it lacks one or more nucleotides relative to the naturally occurring nucleic acid molecule sequence, and / or 4) has been manipulated using molecular cloning techniques so that it has one or more sequence changes or rearrangements relative to the naturally occurring nucleic acid sequence. As a non-limiting example, a cDNA is a recombinant DNA molecule, such as any nucleic acid molecule that has been produced by an in vitro polymerase reaction, or has been ligated with linkers, or has been integrated into a vector (such as a cloning vector or an expression vector), or has been integrated into an RNA replicon.

The nucleic acid may be an RNA sequence encoding a protein or peptide (which may be a heterologous protein or peptide). The method comprises administering to the patient an RNA replicon described herein, wherein the protein or peptide encoded by the replicon is expressed (or transcribed) in the patient, which may be accomplished using cellular components of the patient's body. In any (non-limiting) embodiment herein, the mammal may be a human, livestock, edible animal or companion animal. The animal may also be any bird, fish (e.g., salmonids), poultry or fowl, such as chickens, ducks, geese, turkeys, ostriches, emus, swans, peacocks, pheasants, partridges or guinea fowls. The replicon may be administered in a pharmaceutically acceptable carrier, such as saline, water or another acceptable carrier.

[0094] As used herein, "pharmaceutically acceptable carrier" means any substance suitable for administration to an individual. For example, a pharmaceutically acceptable carrier can be a sterile aqueous solution, such as phosphate buffered saline (PBS) or water for injection. In some embodiments, a pharmaceutically acceptable carrier can be a buffer, a preservative, an isotonic agent, a stabilizer, a surfactant, a wetting agent, an emulsifier, an antioxidant, a filler, or a chelating agent. Of course, such additional ingredients should not adversely affect the overall stability of the pharmaceutical formulation of the present invention.

[0095] The replicon can also be administered as a pharmaceutically acceptable salt. As used herein, "pharmaceutically acceptable salt" means a physiologically or pharmaceutically acceptable salt of a compound (such as a nucleic acid compound or a polynucleotide), that is, a salt that retains the desired biological activity of the parent compound and does not impart undesirable toxicological effects. Pharmaceutically acceptable acidic / anionic salts for use in the present invention include, but are not limited to, acetate, benzenesulfonate, benzoate, bicarbonate, bitartrate, bromide, calcium edetate, camphorsulfonate, carbonate, chloride, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, glyceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrabamin e, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isethionate, lactate, lactobionate, malate, maleate, mandelate, methanesulfonate, methyl bromide, methyl nitrate, methyl sulfate, mucate, naphthenate, nitrate, pamoate, pantothenate, phosphate / diphosphate, polygalacturonate, salicylate, stearate, subacetate, succinate, sulfate, tannate, tartrate, teoclate, toluenesulfonate and triethiodide.

[0096] The present invention also provides a method for administering a heterologous protein or peptide to a mammal, comprising administering to the mammal an RNA replicon encoding the heterologous protein or peptide as described herein, and wherein the heterologous protein or peptide is expressed in the mammal. The method allows administration of a heterologous protein or peptide to a mammal with a lower or eliminated immune response from the mammal compared to administration of naked heterologous proteins and peptides.

[0178] Embodiment 49 is the alphavirus replicon RNA of embodiment 47, wherein the HVD comprises the HVD from the VEEV, except that amino acid residues 335-518 of the nsP3 of the VEEV are replaced with amino acid residues 335-517 of the nsP3 of CHIKV.

[0179] Example 1 - Immunogenicity of VEEV-based replicons

[0180] A VEEV-based alphavirus replicon was constructed by replacing the nucleotide sequence encoding amino acids 335-518 of VEEV nsP3 with the nucleotide sequence encoding amino acids 335-517 of Chikungunya (CHIKV) nsP3 to generate a VEEV-based replicon expressing a VEEV / CHIKV nsP3 chimera (SEQ ID NO: 30). This replacement removed the first motif of the repeat sequence from VEEV and replaced it with the FGDF / FGDF (SEQ ID NO: 20) repeat sequence from the CHIKV genome (at amino acids 479-482 and 497-500). In a parallel experiment, amino acids 335-538 (HVD region) of VEEV nsP3 were replaced with amino acids 335-538 (HVD region) of Sindbis virus (SINV) nsP3 amino acids to generate a replicon encoding a VEEV / SINV nsP3 chimera (SEQ ID NO: 31) (see Figures 2 and 7). This replacement removes the repetitive sequence from VEEV and replaces it with the FGSF / FGSF (SEQ ID NO:21) repetitive sequence from SINV. Replicons containing WT, VEEV / CHIKV or VEEV / SINV chimeric nsP3 and expressing the red firefly luciferase (rFF) reporter gene from subgenomic RNA (SGIα-rFF) were delivered to BHK-21 cells in triplicate by electroporation. After electroporation, a portion of the cells were plated into one well of a 6-well plate and one well of a 96-well plate and allowed to recover for 20 hours. The electroporated cells were stained for the presence of dsRNA and analyzed by flow cytometry to determine the frequency of dsRNA-positive cells as a measure of replicon amplification. It was found that the replicons containing mutant nsP3 replicated to the same level as the replicons containing WT nsP3 ( Figure 2B When luciferase activity was analyzed, no differences were found between replicons containing WT or the indicated mutant forms of nsP3 ( Figure 2C ).

[0181] Example 2 - Expression of heterologous proteins from replicons

[0182] This embodiment detects Figure 2AThe replicon encoding mutant nsP3 (Example 1) expressed recombinant firefly luciferase (rFF) in vivo. 1 or 10 μg of replicon RNA in saline was delivered intramuscularly (IM) to the quadriceps of BALB / c mice. At the indicated time points, in vivo luciferase activity was monitored using a commercially available in vivo imaging system and reported as total flux ( Figure 3A and 3B The data show that replicons expressing mutant forms of nsP3 exhibit similar levels of luciferase activity in vivo compared to replicons containing wild-type nsP3 from VEEV.

[0183] Example 3 - Immunogenicity

[0184] This example examines the immunogenicity of a VEEV-based replicon (from Example 1) encoding a VEEV / CHIKV chimeric form of nsP3 versus a replicon with wild-type (WT) VEEV nsP3. Each replicon encodes and expresses hemagglutinin (HA) from an influenza H5N1 strain as a heterologous protein. 2.0 ug or 0.2 ug of RNA in saline was delivered intramuscularly to the quadriceps of BALB / c mice on day 0 and boosted with the same replicon RNA and dose on day 28. Two weeks after the boost (day 42 after the primary immunization), spleens and serum were collected. Serum was analyzed for HA-specific antibodies ( Figure 4 ). The data showed that the replicon encoding the VEEV / CHIKV nsP3 chimera significantly reduced HA-specific IgG titers compared to the replicon with wild-type nsP3.

[0185] In contrast, analysis of short-term effector and memory precursor effector CD8+ T cells showed no differences in the frequency of HA-specific cells between the different replicons tested ( Figure 5A and 5B ). Figure 5A The frequencies of HA-specific short-term effector CD8+ T cells were similar between wild-type, VEEV / SINV nsP3, and VEEV / CHIKV nsP3 RNA replicons. Figure 5B Similar results were shown for memory effector CD8+ T cells.
