A challenge with RNA-encoded proteins and antibody therapeutics is achieving efficacious levels of the protein or antibody in vivo. Additionally, the discovery and development of antibodies that 1) are suitable for expression from RNA, and 2) potently and specifically neutralize their target, is hampered by a dependence on the isolation of antibody-producing cells from hosts that have either undergone natural exposure to the target pathogen or toxin or have been deliberately immunized with a representative protein. These two requirements present a bottleneck in discovery and development of RNA-encoded antibody therapeutics. Furthermore, in vivo production of virus-like particles (VLPs) derived from non-enveloped viruses has yet to be demonstrated and is complicated by the involvement of nonstructural viral proteases required for processing of the structural polyprotein in trans. Therefore, there is a great unmet need for enhanced nucleic acid-encoded protein and antibody therapeutics that yield a therapeutically meaningful level of protein expression as well as methods for improving the discovery of relevant antibodies, with the intended function, and suitable for expression from nucleic acids, such as RNA.

Provided here are compositions comprising a nucleic acid encoding for a protein or a functional fragment thereof. In some embodiments, the protein is an antigen, an antigen-binding protein, or a fragment thereof. In some embodiments, the antigen is an antigen from a microbial organism. In some embodiments, the antigen is a microbial antigen. In some embodiments, the antigen is a bacterial antigen. In some embodiments, the microbial antigen is a viral antigen. In some embodiments, the viral antigen is a surface protein or a transmembrane protein. In some embodiments, the viral antigen is a spike protein, a glycoprotein, or an envelope protein. In some embodiments, the viral antigen is expressed cytosolically by a host cell or is not secreted by a host cell. In some embodiments, more than one antigen is encoded by a single nucleic acid. In some embodiments, the viral antigen is derived from a non-enveloped virus. In some embodiments, the viral antigen is derived from an enveloped virus. In some embodiments, more than one antigen is derived from a non-enveloped virus. In some embodiments, more than one antigen is derived from an enveloped virus.
Enveloped viruses fuse the viral envelope with a host cellular membrane. Fusion of some enveloped viruses occurs within the low-pH environment of an acidic endosomal compartment. Enveloped viruses typically reach the endosomal compartment via trafficking in clathrin-coated vesicles or the caveolar route. Examples of enveloped viruses include but are not limited to coronaviruses, influenza A, hepatitis C virus, and human immunodeficiency virus (HIV).
Non-enveloped viruses do not use the host secretory system to enter or leave a host cell during infection. Instead, non-enveloped viruses enter the cytosol by directly penetrating the plasma membrane, as well as through a variety of endocytic mechanisms leading to penetration of internal membrane(s), the Golgi, and the endoplasmic reticulum of the host cell. Enteroviruses enter the host cell by receptor-mediate endocytosis. Following endocytosis, uncoating of the virion occurs in the endosome and the positive-stranded RNA along with the covalently-linked VPg protein is released into the cytoplasm. Viral RNA is translated by host ribosomes making a single polyprotein that is catalytically cleaved by enterovirus proteases 2Apro and 3Cpro. After production and accumulation of non-structural proteins, including the viral polymerase, viral RNA is then replicated using the virally-encoded RNA-dependent RNA polymerase to generate a double-stranded RNA. The negative sense RNA serves as the template to make more positive sense RNA. Newly produced RNA can be the template to produce more positive sense RNAs or serve as the genome for progeny viruses. Capsid proteins assemble and newly synthesized positive-stranded viral RNA is packaged into virion. Finally, new progeny virions are released either by non-lytic release, where virions are released in vesicles, or are released when the cell undergoes lysis (lytic release).
Provided herein are compositions comprising a nucleic acid encoding for a viral antigen derived from a non-enveloped virus. In some embodiments, the non-enveloped virus is a double-stranded DNA virus. In some embodiments, the non-enveloped virus is a single-stranded DNA virus. In some embodiments, the non-enveloped virus is a double-stranded RNA virus. In some embodiments, the non-enveloped virus is a single-stranded RNA virus.

In some embodiments, the viral antigen is derived from a Picornaviridae. In some embodiments, the viral antigen is derived from an enterovirus, a coxsackievirus, a rhinovirus, a poliovirus, an echovirus, or a parechovirus.

In some embodiments, the nucleic acids encoding for a structural protein from a non-enveloped virus and a 3CD protease further comprise a non-structural protein from an alphavirus.
Provided here are compositions comprising a nucleic acid encoding for an antibody or an antibody fragment. In some embodiments, the antibody is a monoclonal antibody.

In some embodiments, the composition comprises nucleic acids encoding for polyclonal antibody.
In some embodiments, the antibody is a murine antibody, a humanized antibody, or a fully human antibody, or a single domain heavy chain antibody derived from camelids, sharks, eels, or other species that produce such single-domain antibodies. In some embodiments, the antibody is an immunoglobulin (Ig) molecule. Immunoglobulin (Ig) molecules and immunologically active portions of immunoglobulin molecules (i.e., molecules that contain an antigen binding site that specifically bind an antigen) are comprised of four polypeptide chains, two heavy (H) chains and two light (L) chains, or any functional fragment, mutant, variant, or derivation thereof, which retains the essential epitope binding features of an Ig molecule. Such mutant, variant, or derivative antibody formats are known in the art. Non-limiting embodiments of which are discussed below, and include but are not limited to a variety of forms, including full length antibodies and antigen-binding portions thereof; including, for example, an immunoglobulin molecule, a monoclonal antibody, a chimeric antibody, a CDR-grafted antibody, a human antibody, a humanized antibody, a single chain antibody, a Fab, a F(ab′), a F(ab′)2, a Fv antibody, fragments produced by a Fab expression library, a disulfide linked Fv, a scFv, a single domain antibody (dAb), a diabody, a multispecific antibody, a dual specific antibody, an anti-idiotypic antibody, a bispecific antibody, a functionally active epitope-binding fragment thereof, bifunctional hybrid antibodies. In some embodiments, the immunoglobulin molecule is an IgG, IgE, IgM, IgD, IgA, or an IgY isotype immunoglobulin molecule. In some embodiments, the antibody or immunoglobulin molecules provided herein are a specific subclass of immunoglobulin molecule. In some embodiments, the immunoglobulin molecule is an IgG1, an IgG2, an IgG3, an IgG4, an IgGA1, or an IgGA2 subclass immunoglobulin molecule. In a full-length antibody, each heavy chain is comprised of a heavy chain variable domain (abbreviated herein as HCVR or VH) and a heavy chain constant region. The heavy chain constant region is comprised of three domains: CH1, CH2, and CH3. Each light chain is comprised of a light chain variable domain (abbreviated herein LCVR as VL) and a light chain constant region. The light chain constant region is comprised of one domain, CL. The VH and VL regions can be further subdivided into regions of hypervariability, termed complementarity determining regions (CDRs), interspersed with regions that are more conserved, termed framework regions (FR). Each VH and VL is composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. This structure is well-known to those skilled in the art. The chains are usually linked to one another via disulfide bonds. Furthermore, in humans, the light chain may comprise a kappa chain or a lambda chain. Complementarity Determining Regions (“CDRs”), i.e., CDR1, CDR2, and CDR3) are the amino acid residues of a heavy or light chain variable domain specific for antigen binding. Each variable domain typically has three CDR regions identified as CDR1, CDR2 and CDR3. Each complementarity determining region can comprise amino acid residues from a “complementarity determining region” as defined by Kabat (i.e., about residues 24-34 (L1), 50-56 (L2) and 89-97 (L3) in the light chain variable domain and 31-35 (HI), 50-65 (H2) and 95-102 (H3) in the heavy chain variable domain; Kabat et al., Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md. (1991)) and/or those residues from a “hypervariable loop” (i.e., about residues 26-32 (LI), 50-52 (L2) and 91-96 (L3) in the light chain variable domain and 26-32 (HI), 53-55 (H2) and 96-101 (H3) in the heavy chain variable domain; Chothia and Lesk J. Mol. Biol. 196:901-917 (1987)). In some instances, a complementarity determining region can include amino acids from both a CDR region defined according to Kabat and a hypervariable loop. The exact boundaries of these CDRs have been defined differently according to different systems. The system described by Kabat (Kabat et al, Sequences of Proteins of Immunological Interest (National Institutes of Health, Bethesda, Md. (1987) and (1991)) not only provides an unambiguous residue numbering system applicable to any variable region of an antibody, but also provides the residue boundaries defining the three CDRs. These CDRs may be referred to as Kabat CDRs. Chothia and coworkers (Chothia & Lesk, J. Mol. Biol, 196:901-917 (1987) and Chothia et al., Nature 342:877-883 (1989)) found that certain sub-portions within Kabat CDRs adopt nearly identical peptide backbone conformations, in spite of great diversity at the level of amino acid sequence. These sub-portions were designated as LI, L2 and L3 or HI, H2 and H3 where the “L” and the “H” designates the light chain and the heavy chains regions, respectively. These regions may be referred to as Chothia CDRs, which have boundaries that overlap with Kabat CDRs. Other boundaries defining CDRs overlapping with the Kabat CDRs have been described by Padlan (FASEB). 9: 133-139 (1995)) and MacCallum (J Mol Biol 262(5):732-45 (1996)). Still other CDR boundary definitions may not strictly follow one of the above systems, but will nonetheless overlap with the Kabat CDRs, although they may be shortened or lengthened in light of prediction or assay result that particular residues or groups of residues or even entire CDRs do not significantly impact antigen binding. The alignment of the CDR sequences can be conducted using publicly available software such as BLAST, Align, and the international ImMunoGeneTics information system (IMGT). Those skilled in the art can determine the appropriate parameters for alignment, but the default parameters for BLAST are specifically contemplated.

Methods for assessing the presence of antibody neutralization of a virus or a viral antigen can be accomplished, e.g., by cellular impedance and live cell imaging assays. Cellular impedance assays include wells or plates with gold impedance biosensor arrays that measure the flow of electric current within a well that has been seeded with cells. Impedance is measured before, during, and after viral infection. During active viral infection, the interaction between the cells and the biosensors become weak and a small impedance of electric current (or increased flow of electric current) is detected as compared to cells that are not infected by a virus. Real-time impedance measurements can be used to track changes in cell number, cell size, cell-substrate attachment strength, and cell-cell interactions (i.e. barrier function). Because each of these parameters changes during a typical viral cytopathic effect (CPE), impedance provides a very sensitive readout of host cell health throughout the full continuum of a viral infection. Real-time impedance measurements in the presence and absence of a composition provided herein is useful to determine the effect of antibody function and suppression of CPE. Antibody-mediated suppression of the CPE is readily detected as changes in both the kinetics and magnitude of the impedance signal. Plotting the value of the impedance signal at various time points as a function of antibody concentration can produce a dose response curve to yield IC50 measurements and determine the percentage of neutralization relative to control readings.

The microfluidized NP-30 without inorganic core formulation was terminally filtered with a 200 nm pore-size polyethersulfone (PES) filter and stored at 2-8 degrees Celsius (° C.). DOTAP and Squalene concentration were measured by RP-HPLC.
Stability. A nanoparticle according to NP-1 was placed into a stability chamber at the indicated temperatures. The stability was determined by particle size measurement using dynamic light scattering. The results show that the NP-1 formulation formed a stable colloid when stored at 4, 25 and 42 degrees Celsius. Time measurements were taken over 4 weeks. As shown in
A plasmid encoding a T7 promoter followed by the 5′ and 3′ UTRs and nonstructural genes of Venezuelan equine encephalitis virus (VEEV) strain TC-83 was generated using standard DNA synthesis and cloning methods. The VEEV replicon mRNA backbone is set forth in SEQ ID NO: 8.
EV-D68 is a single serotype of the EV-D species within the Enterovirus genus. EV-D68 can be further divided into 4 clades (A, B, C, and D) and clade B further divided into 3 subclades (B1, B2, and B3) based on genotype. Full-genome sequences of contemporary EV-D68 isolates from recent outbreaks were aligned (MUSCLE) and a maximum-likelihood phylogenetic tree was constructed (PhyML) using a GTR best-fit nucleotide substitution model. A single isolate (red box) from each clade was then selected for protein sequence variation analysis (
Neutralizing antibodies against conformationally-native and diverse epitopes presented on EV-D68 VLPs launched from repRNA in vivo were induced in alpacas using repRNA/NP-1 immunization. To identify broadly reactive and cross-neutralizing antibodies, repRNA encoding VLPs from the 6 sub-clades of the EV-D68 serotype were designed and used. VLPs of enveloped viruses, including those of alphaviruses and flaviviruses that bud from the host cell, are produced in vivo following DNA/RNA genetic immunization approaches. However, in vivo production of VLPs derived from non-enveloped viruses has yet to be demonstrated and is complicated by the involvement of nonstructural viral proteases required for processing of the structural polyprotein in trans. It is established that co-expression of the P1 and 3CD proteins of enteroviruses in insect and mammalian cell lines results in efficient formation of VLPs for enterovirus 71, coxsackievirus A16, coxsackievirus A6, as well as EV-D68.
Following the model of virion production described in Example 4, repRNAs encoding the P1 and 3CD protein genes of EV-D68 (US/MO/14-18947) were designed, where both open reading frames were encoded on a single repRNA molecule separated by either an internal ribosomal entry site (IRES) or by a ribosomal skipping peptide sequence derived from thosea asigna virus (T2A) to facilitate production of both proteins from the same RNA molecule (
Densitometric analysis of the western blots was performed and it was concluded that the IRES-based approach resulted in more efficient VLP production (
Using the IRES strategy from Example 5, six clade-specific versions, as well as a 3CD deletion mutant (
A high-throughput assay for rapid screening of neutralizing antibody activity was developed, comprising a cell impedance-based assay to monitor and quantify EV-D68-mediated cell morphology changes on monolayers of rhabdomyosarcoma (RD) cells over time in each well of a 96-well plate. This highly reproducible, virus-agnostic method was previously utilized for screening of human monoclonal antibodies against a variety of viral pathogens. The method was adapted for screening enriched phage libraries for EV-D68-neutralizing VHHs, we selected 92 colonies from an EV-D68-enriched phage library and induced expression of encoded VHHs along with 2 negative control colonies in a 96-well microplate. Supernatants were then clarified by centrifugation and this crude preparation of phage library-expressed VHHs was incubated with EV-D68 (US/MO-14-18947) and then overlaid, with the appropriate antibiotic, onto a monolayer of RD cells seeded on ePlates (Agilent) the night before along with 2 no-virus positive controls. These 96 total samples were then monitored on an xCELLigence™ real time cell analysis multiplate reader (Agilent, Santa Clara, CA), with cell impedance data collections every 15 minutes over a 3-day period (
The assay assessed delivery of various nanoparticles having DNA or RNA admixed therewith. Briefly, DNA encoding secreted embryonic alkaline phosphatase (SEAP) or replicon RNA encoding an RNA polymerase and SEAP were prepared and mixed with a nanoparticle of NP-1 or NP-3. Conditions are provided in Table 4. BALB/c female mice were injected intramuscularly (IM). Nucleic acid preparations for dilutions are provided in Table 5. Nanoparticle preparations are provided in Table 6. Nucleic acid-nanoparticle complexes were formed by adding 150 μl diluted NP-1 or NP-3 to 150 μl diluted DNA or RNA, then incubated for at least 30 minutes.
Mice were inoculated on day 0 according to the treatment groups. Blood was collected on days 4, 6 and 8, allowed to clot, and the serum was collected and stored at minus 80 degrees Celsius. Serum samples were thawed and SEAP detection was assessed. A chemiluminescent substrate of SEAP was provided, and activity was measured based on the light generated, and quantitated as Relative Luminescence Units (RLUs). Results are shown in
The following was performed to assay activity of lyophilized NP-1 with replicon RNA encoded SARS-CoV-2 spike antigen sequence, physicochemical properties of reconstituted vaccines, potency, and immunogenicity. Briefly, materials in Table 7 were used.
Preparation of formulation complexes. Compositions of lipid nanoparticle/RNA complexes were prepared in this assay as shown below in Table 8. NP-1 or NP-7 and repRNAs were complexed at a N-to-P ratio of 15 and complexed to obtain a final repRNA concentration of 50 mg/ml or 100 mg/ml (“2×” material), and 10% or 20% w/v sucrose content, respectively. Complexed material with 10% sucrose (50 mg/ml repRNA) contained 5 mM sodium citrate while that with 20% sucrose (100 mg/ml repRNA) contained 10 mM citrate. Complexes were filled in 2 ml sterile, depyrogenated and baked vials. Complexes with 10% sucrose were filled at 0.7 ml per vial and 20% sucrose at 0.35 ml per vial. Vials were then either lyophilized and stored or stored as is in liquid form. Storage temperature was 25 degrees Celsius or 42 degrees Celsius for 1 week. Quantity of lyophilized and liquid vials per composition is summarized in Table 8.
Lyophilization cycle. An SP VirTis Advantage Pro tray and batch lyophilizer with inert gas fill and stoppering capability was used. Summary of the lyophilization cycle is shown in Table 9 below. After end of cycle, vials were backfilled with nitrogen at 48 torr and stoppered, before equilibrating to room pressure.
Condition groups. A summary of 14 groups analyzed in this assay is provided in Table 10 below. Groups 1 and 4, as indicated in the storage column, were prepared fresh to serve as positive controls for comparison with standard protocol for vaccine preparation.
Immunogenicity assay. Induction of andi-spike IgG responses were evaluated in 6 to 8 weeks old female C57BV/6 mice. A group size of 5 mice was used. The schedule is shown in Table 11.
After 1 week of storage in 25 degrees Celsius or 42 degrees Celsius stability chamber, lyophilized nanoparticle/RNA complexes were reconstituted in 0.7 ml sterile milliQ water and gently swirled until no particles were visible to the naked eye. Particle size (z-average) and size distribution (PDI) of the complexes was measured and is summarized in
Agarose gel electrophoresis of phenol-chloroform extracted repRNA. Liquid formulations of NP-1/repRNA and NP-7+repRNA in 10% sucrose or 20% sucrose, stored for 1 week at NP-1/repRNA and NP-7+repRNA, resulted in partial or full degradation of repRNA product, respectively. (Data not shown.) Lyophilization of NP-1/repRNA and NP-7+repRNA in 10% sucrose or 20% sucrose preserved repRNA integrity after 1 week storage at NP-1/repRNA and NP-7+repRNA. (Data not shown.)
Potency Assay. Lyophilized NP-1/WT-S in 10% sucrose stored for 1 week at 25 degrees Celsius produced a dose-dependent expression of spike protein in transfected BHK cells. The expression profile was similar to freshly complexed NP-1/WT-S. 1 week storage at 42 degrees Celsius of lyophilized NP-1/WT-S in 10% sucrose significantly reduced in vitro protein expression. Liquid NP-1/WT-S in 10% sucrose stored for 1 week at 25 degrees Celsius or 42 degrees Celsius did not produce spike protein in BHK cells. (Data not shown.)
Anti-D614G spike IgG responses by ELISA. Serum anti-D614G spike IgG levels was assessed on days 14 and 28 post-prime shown below in
Day 28 post-prime anti-D614G IgG response. After 1 week at 25 degrees C., liquid NP-1/WT-S in 10% sucrose resulted in a 3 statistically significant reduction in anti-spike IgG compared to the freshly prepared NP-1/WT-S positive control. There was no significant difference in mean IgG levels between freshly prepared NP-1/WT-S and lyophilized NP-1/WT-S in 10% sucrose stored for 1 week at 25 degrees C.
After 1 week at 42 degrees C., lyophilized NP-/WT-S in 10% sucrose induced 100% seroconversion but mean IgG level was significantly reduced compared to freshly prepared NP-1/WT-S. Summary mean+/−standard deviation IgG concentration data from day 28 post-immunization, including p-values determined by ordinary one-way ANOVA comparing against the freshly prepared NP-1/WT-S positive control, shown in Table 13. P<0.05 are considered statistically significant differences.
Comparison of fresh versus lyophilized formulations. Day 28 post-prime anti-D614G spike IgG concentration in serum is shown in
Recombinant VHH G12, which was identified in the phage-display library after panning against clade B1 enterovirus D68 (EV-D68). The construct was expressed in and purified from E. coli and then assayed for neutralizing activity against all 6 genotypes of EV-68 by real time cell analysis (RTCA) assay.
While 50% inhibitory concentrations (IC50) where low (˜1 nM) for homologous virus (clade B1) and the closely related clade B2 virus, significant loss of neutralizing activity was observed against clades A1, A2, B3, and C, with 5-20-fold reductions in potency (
Four RNA constructs were generated as provided in Table 14 below and shown in
VP1 HA2 was generated with hemagglutinin A from influenza, an enveloped virus, to secrete VP1 proteins. The constructs were each expressed in and purified from E. coli and then assayed for neutralizing activity against EV-68 by real time cell analysis (RTCA) assay.
Neutralization titers showed that constructs that did not have a 3CD protease did not neutralize EV-D68. The full-length polyprotein with 3CD protease was necessary for inducing neutralizing antibodies to EV-D68 (
Six non-human primates were immunized with EV-D68 B1 repRNA vaccine (SEQ ID NO: 18) and blood was drawn according to the schedule in
Non-human primates vaccinated with EV-D68 Bi repRNA vaccine produced 50% neutralization titers within 7 days after vaccination and neutralized the B1 enterovirus (
