[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. Provisional Patent Application No. 62 / 342,784, filed May 27, 2016, which is incorporated by reference in its entirety and to which the inventors claim priority under 35 U.S.C. § 120. [Background technology]

[0002] Messenger RNA (mRNA) is a polymer containing many linked nucleotides, each consisting of a sugar, a phosphate, and a base. Each mRNA polymer stores genetic information along a chain of nucleotides. Messenger RNA polymers transmit genetic information from the DNA in the cell's nucleus to the cytoplasm where proteins are made. Each triplet of nucleotides in the mRNA is called a codon, and each codon specifies the identity of an amino acid in the translated protein.

[0003] Cells can also take up and translate exogenous RNA, but many factors influence efficient uptake and translation. For example, the immune system recognizes many exogenous RNAs as foreign and elicits responses aimed at inactivating them. Summary of the Invention [Means for solving the problem]

The nucleic acid construct may be, for example, a complementary deoxyribonucleic acid DNA template. The nucleic acid construct may encode an axonemal dynein intermediate chain 1 protein or a variant thereof at a level at least about 1.5-fold, at least about 5-fold, or another suitable amount of multiples higher than the level in cells exposed to a composition comprising a nucleic acid construct that does not comprise a codon encoding the axonemal dynein intermediate chain 1 protein or a variant thereof.

[0019] overview The present disclosure provides compositions and methods for treating conditions related to the maintenance and function of cilia using nucleic acids encoding proteins or protein fragments. Many eukaryotic cells carry appendages often called cilia or flagella, the inner core of which contains a cytoskeletal structure called axoneme. The axoneme can function as the backbone of the cytoskeletal structure, supporting the structure and in some cases bending the structure. Usually, the inner structure of the axoneme is common to both cilia and flagella. Cilia are often found in the lining of the airways, reproductive system and other organs and tissues. Flagella, like cilia, are tail-like structures that can propel cells, such as sperm cells, forward.

[0020] If cilia do not function normally in the airways, bacteria can remain in the airways and cause infection. In the airways, cilia move back and forth in a coordinated manner to move mucus toward the throat. This movement of mucus helps to clear fluid, bacteria, and particles from the lungs. Many infants affected by cilia and flagella dysfunction experience breathing problems at birth, suggesting that cilia play an important role in clearing fetal fluid from the lungs. Beginning in infancy, subjects affected by cilia dysfunction can develop frequent respiratory infections.

[0021] Primary ciliary dyskinesia is a condition characterized by chronic airway infections, abnormally located internal organs, and the inability to have children (infertility). The signs and symptoms of the condition are caused by abnormal cilia and flagella. Subjects suffering from primary ciliary dyskinesia often have year-round stuffy nose and chronic cough. Chronic airway infections can result in a condition called bronchiectasis, which damages the passageways called bronchi that lead from the trachea to the lungs, causing life-threatening breathing problems.

[0022] In some cases, the nucleic acid construct, vector, or composition of the disclosure comprises one or more nucleotide sequences encoding an axonemal dynein intermediate chain 1 protein or variant thereof, which sequences provide for heterologous or enhanced expression of the axonemal dynein intermediate chain 1 protein or variant thereof in cells of a subject. In some cases, the nucleic acid construct, vector, or composition also comprises the genetic code for the 5' untranslated region (UTR) and 3' UTR of SEQ ID NOs: 1-9, as set forth below. [Table 1] TIFF0007672786000002.tif69170

[0023] Primary ciliary dyskinesia, related conditions and their treatment The disclosed methods, constructs and compositions provide a method for treating primary ciliary dyskinesia (PCD), also known as primary ciliary dyskinesia or Kartagener syndrome. PCD is typically considered to be a rare, ciliopathy, autosomal recessive genetic disorder that frequently causes defects in the activity of cilia in the lining of the airways (lower and upper respiratory tract, sinuses, Eustachian tube, middle ear) and fallopian tubes, as well as in the flagella of sperm cells.

[0024] Some individuals with primary ciliary dyskinesia have abnormally positioned organs in the chest and abdomen. These abnormalities arise early in embryonic development when the differences between the left and right sides of the body are established. Approximately 50% of people with primary ciliary dyskinesia have mirror image inversion of the internal organs (total situs inversus). For example, in these individuals, the heart is on the right side of the body instead of the left. When a person with primary ciliary dyskinesia has total situs inversus, they are often said to have Kartagener syndrome.

[0025] Approximately 12% of people with primary ciliary dysmetria have a condition known as heterotaxy syndrome or heterotaxy, characterized by abnormalities of the heart, liver, intestine, or spleen. These organs may be structurally abnormal or inappropriately located. Additionally, affected individuals may have no spleen (asplenia) or multiple spleens (polysplenia). Heterotaxis syndrome results from problems establishing the left and right sides of the body during embryonic development. The severity of heterotaxy varies greatly among affected individuals.

[0026] Primary ciliary dyskinesia can also lead to infertility. Vigorous flagellum movement may be required to propel the sperm cell toward the female egg cell. Because the sperm of affected subjects do not move properly, men with primary ciliary dyskinesia usually cannot father children. Infertility occurs in some affected women and is usually associated with abnormal cilia in the fallopian tubes.

[0027] Another feature of primary ciliary dyskinesia is recurrent ear infections (otitis media), especially in young children. If left untreated, otitis media can lead to permanent hearing loss. The ear infections are likely related to abnormal cilia in the inner ear.

[0028] Rarely, individuals with primary ciliary dyskinesia have fluid accumulation in the brain (hydrocephalus), presumably due to abnormal cilia in the brain.

[0029] The polyribonucleotides of the present disclosure can be used, for example, to treat a subject having or at risk of having primary ciliary dyskinesia or any other condition associated with a defect or dysfunction in a gene whose function is linked to the maintenance and function of cilia. Non-limiting examples of genes associated with primary ciliary dysfunction include armadillo repeat containing 4 (ARMC4), chromosome 21 open reading frame 59 (C21orf59), coiled-coil domain containing 103 (CCDC103), coiled-coil domain containing 114 (CCDC114), coiled-coil domain containing 39 (CCDC39), coiled-coil domain containing 40 (CCDC40), coiled-coil domain containing 65 (CCDC65), cyclin O (CCNO), dynein assembly factor 1 (DNAAF1), dynein assembly factor 2 (DNAAF2), dynein assembly factor 3 (DNAAF3), dynein assembly factor 5 (DNAAF5), axonemal dynein heavy chain 11 (DNAH11), axonemal dynein heavy chain 5 (DNAH5), axonemal dynein heavy chain 6 (DNAH6 ), axonemal dynein heavy chain 8 (DNAH8), axonemal dynein intermediate chain 2 (DNAI2), axonemal dynein light chain 1 (DNAL1), dynein regulatory complex subunit 1 (DRC1), dyslexia susceptibility 1 candidate 1 (DYX1C1), growth arrest specific 8 (GAS8), axonemal central paired apparatus protein (HYDIN), leucine-rich repeat containing 6 (LRRC6), NME / NM23 family member 8 (NME8), oral-facial-digital syndrome 1 (OFD1), retinitis pigmentosa GTPase regulator (RPGR), radial spokehead 1 homolog (Chlamydomonas) (RSPH1), radial spokehead 4 homolog A (Chlamydomonas) (RSPH4A), radial spokehead 9 homolog (Chlamydomonas) (RSPH9), sperm-associated antigen 1 (SPAG1), and zinc finger MYND type containing 10 (ZMYND10).

[0030] In some cases, the composition includes a nucleic acid construct encoding axonemal dynein intermediate chain 1 (DNAI1), which when translated in the subject's cells produces a polypeptide that treats the subject having or at risk of having primary ciliary dysfunction. The DNAI1 gene can provide instructions for making a protein that is part of a group (complex) of proteins called dynein. This complex functions within the cilium. The coordinated back and forth movement of the cilium can move the cell or the fluid around the cell, and dynein generates the force necessary for the cilia to move. Within the core of the cilium (axoneme), the dynein complex is part of structures known as the inner dynein arm (IDA) and the outer dynein arm (ODA), depending on their location. The coordinated movement of the dynein arms bends the entire axoneme back and forth. IDA and ODA have various combinations of protein components (subunits) classified as heavy, intermediate or light chains depending on their weight. The DNAI1 gene provides instructions for making the intermediate chain 1 found in ODA. The other subunits may be generated from different genes administered to the subject in the same or separate compositions, or alternatively, the other subunits may be generated by a single nucleic acid construct that encodes functional components of a dynein inner arm or outer arm.

[0031] At least 21 mutations in the DNAI1 gene have been found to cause primary cilia dyskinesia, a condition characterized by respiratory tract infections, abnormal organ configurations, and the inability to have children (infertility). DNAI1 gene mutations result in missing or abnormal intermediate strand 1. Without a normal version of this subunit, ODA cannot form properly and may be shortened or missing. As a result, cilia cannot generate the force required to bend back and forth. Ciliary defects lead to the characteristics of primary cilia dyskinesia. In some cases, the present disclosure provides nucleic acids engineered to replace or supplement the function of endogenous DNAI1 proteins containing the IVS1+2_3insT (219+3insT) mutation. In some cases, the present disclosure provides nucleic acids engineered to replace or supplement the function of endogenous DNAI1 proteins containing the second most common A538T mutation.

[0032] In some cases, the composition comprises a nucleic acid construct encoding axonemal dynein intermediate chain 2 (DNAI2), which when translated in the cells of a subject, produces a polypeptide that treats a subject with or at risk of having primary ciliary dyskinesia.The DNAI2 gene is part of the dynein complex of respiratory cilia and sperm flagella.Mutations in this gene are associated with primary ciliary dyskinesia type 9, a disorder characterized by abnormalities in motile cilia, respiratory infections leading to chronic inflammation and bronchiectasis, and abnormalities in sperm tails.

[0033] In some cases, the composition includes a nucleic acid construct encoding armadillo repeat containing 4 (ARMC4), which when translated in the cells of a subject, produces a polypeptide that treats a subject having or at risk of having primary ciliary dyskinesia. The protein encoded by the ARMC4 gene contains 10 armadillo repeat motifs (ARM) and one HEAT repeat, and has been shown to localize to the ciliary axoneme and ciliary base of respiratory cells. Mutations in the ARMC4 gene can cause partial dynein outer arm (ODA) deficiency in respiratory cilia.

[0034] In some cases, the composition comprises a nucleic acid construct encoding chromosome 21 open reading frame 59 (C21orf59), which when translated in the subject's cells produces a polypeptide that treats the subject with or at risk of having primary ciliary dyskinesia. The protein encoded by the C21orf59 gene can play an important role in dynein arm assembly and motile cilia function. Mutations in this gene can result in primary ciliary dyskinesia.

Amounts effective for this use may vary based on the severity and course of the disease or condition, the efficiency of transfection of the nucleic acid construct(s), vector(s), engineered polyribonucleotide(s) or composition(s), the affinity of the encoded polypeptide for the target molecule, previous treatments, the subject's health, weight, response to drugs, and the judgment of the treating physician.

[0067] The nucleic acid construct, vector, engineered polyribonucleotide or composition can be administered to the subject as soon as possible after the onset of symptoms. The nucleic acid construct(s), vector(s), engineered polyribonucleotide(s) or composition can be administered as soon as practical after the onset of a disease or condition is detected or suspected, for the period required to treat the disease, for example, about 1 month, about 6 months, about 12 months, about 18 months, about 24 months, or any suitable period. The length of the treatment period can vary for each subject.

[0068] Altered nucleotide usage in coding regions to enhance mRNA stability for transcript therapy Hydrolysis of oligonucleotides suggests that the reactivity of the phosphodiester bond linking two ribonucleotides in single-stranded (ss)RNA depends on the nature of those nucleotides. At pH 8.5, the susceptibility of dinucleotide cleavage when embedded in a ssRNA dodecamer can vary by an order of magnitude. Under near-physiological conditions, RNA hydrolysis usually begins with S cleavage by a 2'-oxygen nucleophile on the adjacent phosphorus target center opposite the 5'-oxyanion leaving group. N Type 2 attack involves the production of two RNA fragments with 2',3'-cyclic phosphate and 5'-hydroxyl termini. The backbone in these steps is modified by the S-linking of the 2'-OH on adjacent phosphodiester bonds. NMore reactive cleavable phosphodiester bonds may include 5'-UpA-3' (R1=U1, R2=A) and 5'-CpA-3' (R1=C, R2=A), as these can most easily assume the "in-line" conformation required for type 2 nucleophilic attack. Furthermore, the interferon-regulated dsRNA-activated antiviral pathway generates 2'-5' oligoadenylates that bind to ankyrin repeats leading to activation of RNase L endoribonuclease. RNase L efficiently cleaves ssRNA at UA and UU dinucleotides. Finally, U-rich sequences are potent activators of RNA sensors including Toll-like receptors 7 and 8 and RIG-I, making reduction of overall uridine content a potentially attractive approach for reducing the immunogenicity of therapeutic mRNAs.

[0069] Altered nucleotide usage schemes, which aim to reduce the number of more reactive 5'-U(U / A)-3' dinucleotides within and across codons of modified mRNAs, partially alleviate the limitations imposed by the inherent chemical instability of RNA. At the same time, reducing the U content in RNA transcripts reduces their immunogenicity. The present disclosure relates to RNA transcripts containing altered open reading frames (ORFs). In particular, we propose a method involving a substantial reduction of 5'-U(U / A)-3' dinucleotides within protein coding regions resulting in stabilized therapeutic mRNAs.

The term nucleic acid includes any compound and / or substance that contains a polymer of nucleotides. A nucleotide polymer that contains more than 50% ribose bases or ribonucleotide analogs is referred to as a polyribonucleotide. A nucleotide polymer may use altered nucleotide usage to code for a protein, such as DNAI1 or DNAH5, or a functional fragment thereof.

A nucleic acid construct, vector, engineered polyribonucleotide, or composition may be derived from a nucleic acid carrying a mutated gene and a polymorphism.

[0071] In addition to the four standard ribonucleotides, adenosine, guanosine, cytidine and uridine, some cellular RNAs also contain many structurally diverse ribonucleotides. About 100 structurally different nucleotides or nucleotide analogs have been identified in transfer RNA (tRNA), ribosomal RNA (rRNA), messenger RNA (mRNA) and small nuclear RNA (snRNA). In tRNA, some nucleotides may be important determinants of the specificity and efficiency of aminoacylation and codon recognition. Such structurally diverse ribonucleotides may be modified ribonucleotides or nucleotide analogs. In some cases, the polynucleotides of the present disclosure are engineered to contain ribonucleotide analogs.

[0076] In some cases, the nucleic acid construct(s), vector(s), engineered polyribonucleotide(s), or composition(s) encode an axonemal dynein intermediate chain 1 protein or variant thereof at a level that is increased by at least about 1.5-fold compared to the level in a cell exposed to a composition comprising a nucleic acid construct that does not include a codon encoding an axonemal dynein intermediate chain 1 protein or variant thereof. In some cases, the fold is at least about 1.1, at least about 1.2, at least about 1.3, at least about 1.4, at least about 1.5, at least about 2, at least about 3, at least about 4, at least about 5, at least about 10, at least about 20, at least about 30, at least about 40, at least about 50, at least about 60, at least about 70, at least about 80, at least about 90, or at least about 100.

[0077] A polyribonucleotide may have the same nucleotide analogue or modified nucleotide, or a mixture of different nucleotide analogues or modified nucleotides. The nucleotide analogue or modified nucleotide may have a structural change that is naturally or non-naturally occurring in messenger RNA. A mixture of various analogues or modified nucleotides may be used. For example, one or more analogues in a polynucleotide may have a natural modification, and another portion may have a modification that is not naturally found in mRNA.

[0079] In some cases, at least about 5% of the nucleic acid construct(s), vector(s), engineered polyribonucleotide(s) or composition comprises non-naturally occurring (e.g., modified, analog or engineered) uridine, adenosine, guanine or cytosine such as the nucleotides described herein. In some cases, 100% of the modified nucleotides in the composition are either 1-methylpseudouridine or pseudouridine. In some cases, at least about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% of the nucleic acid construct(s), vector(s), engineered polyribonucleotide(s) or composition comprises non-naturally occurring uracil, adenine, guanine or cytosine.

[0080] The nucleic acid construct(s), vector(s) or engineered polyribonucleotide(s) of the present disclosure may comprise one or more promoter sequences and any associated regulatory sequences. The promoter sequence and / or associated regulatory sequences may comprise any number of modified or unmodified nucleotides, and any number of nucleic acid analogs. The promoter sequence and / or any associated regulatory sequences may be, for example, at least 2 bases or base pairs, 3 bases or base pairs, 4 bases or base pairs, 5 bases or base pairs, 6 bases or base pairs, 7 bases or base pairs, 8 bases or base pairs, 9 bases or base pairs, 10 bases or base pairs, 11 bases or base pairs, 12 bases or base pairs, 13 bases or base pairs, 14 bases or base pairs, 15 bases or base pairs, 16 bases or base pairs, 17 bases or base pairs, 18 bases or base pairs, 19 bases or base pairs, 20 bases or base pairs, 21 bases or base pairs, 22 bases or base pairs, 23 bases or base pairs, 24 bases or base pairs, 25 bases or base pairs, 26 bases or base pairs, The nucleic acid sequence may comprise at least 10,000 bases or base pairs, 27 bases or base pairs, 28 bases or base pairs, 29 bases or base pairs, 30 bases or base pairs, 35 bases or base pairs, 40 bases or base pairs, 50 bases or base pairs, 75 bases or base pairs, 100 bases or base pairs, 150 bases or base pairs, 200 bases or base pairs, 300 bases or base pairs, 400 bases or base pairs, 500 bases or base pairs, 600 bases or base pairs, 700 bases or base pairs, 800 bases or base pairs, 900 bases or base pairs, 1000 bases or base pairs, 2000 bases or base pairs, 3000 bases or base pairs, 4000 bases or base pairs, 5000 bases or base pairs, or at least 10,000 bases or base pairs.Promoter sequences and / or associated regulatory sequences may comprise any number of modified or unmodified nucleotides, for example at most 10,000 bases or base pairs, 5,000 bases or base pairs, 4,000 bases or base pairs, 3,000 bases or base pairs, 2,000 bases or base pairs, 1,000 bases or base pairs, 900 bases or base pairs, 800 bases or base pairs, 700 bases or base pairs, 600 bases or base pairs, 500 bases or base pairs, 400 bases or base pairs, 300 bases or base pairs, 200 bases or base pairs, 100 bases or base pairs, 75 bases or base pairs, 50 bases or base pairs, 40 bases or base pairs, 35 bases or base pairs, 30 bases or base pairs, 29 bases or base pairs , 28 bases or base pairs, 27 bases or base pairs, 26 bases or base pairs, 25 bases or base pairs, 24 bases or base pairs, 23 bases or base pairs, 22 bases or base pairs, 21 bases or base pairs, 20 bases or base pairs, 19 bases or base pairs, 18 bases or base pairs, 17 bases or base pairs, 16 bases or base pairs, 15 bases or base pairs, 14 bases or base pairs, 13 bases or base pairs, 12 bases or base pairs, 11 bases or base pairs, 10 bases or base pairs, 9 bases or base pairs, 8 bases or base pairs, 7 bases or base pairs, 6 bases or base pairs, 5 bases or base pairs, 4 bases or base pairs, 3 bases or base pairs, or 2 bases or base pairs.

[0081] In some cases, less than all of the nucleotides in the promoter sequence or related regulatory region are nucleotide analogs or modified nucleotides.For example, in some cases, 99%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10% or 5% or less of the nucleotides in the promoter or related regulatory region.In some cases, all of the nucleotides in the promoter or related regulatory region are nucleic acid analogs or modified nucleotides.

[0082] The nucleic acid construct(s), vector(s), engineered polyribonucleotide(s) or composition of the present disclosure may include engineered 5' cap structures or 5' caps may be added to polyribonucleotides in cells. The 5' cap structure of an mRNA may participate in binding to mRNA cap binding protein (CBP) and contribute to the stability and translational capacity of the mRNA in cells through the binding of CBP to poly(A) binding protein to form mature pseudo-circular mRNA species. The 5' cap structure may also participate in nuclear transport, increasing mRNA stability, and aiding in the removal of 5' proximal introns during mRNA splicing.

[0083] The nucleic acid construct(s), vector(s) or engineered polyribonucleotide(s) can be capped at the 5' end to generate a 5'-GpppN-3'-triphosphate linkage between the terminal guanosine cap residue of the mRNA molecule and the 5'-terminal transcribed sense nucleotide. The cap structure can include a modified or unmodified 7-methylguanosine linked to the first nucleotide via a 5'-5' triphosphate bridge. This 5'-guanylate cap can then be methylated to generate an N7-methyl-guanylate residue (Cap 0 structure). The ribose sugar of the terminal and / or pre-terminal transcribed nucleotide at the 5' end of the mRNA can be 2'-O-methylated (Cap 1 structure). 5' cap removal by hydrolysis and cleavage of the guanylate cap structure can target nucleic acid molecules such as mRNA molecules for degradation.

[0084] In some cases, the cap may contain additional modifications, including methylation of the 2' hydroxyl groups of the first two ribose sugars at the 5' end of the mRNA. For example, eukaryotic cap 1 has a 2'-hydroxyl group methylated on the first ribose sugar, while cap 2 has a 2'-hydroxyl group methylated on the first two ribose sugars. The 5' cap may be chemically similar to the 3' end of an RNA molecule (the 5' carbon of the capping ribose is attached, as well as free 3'-hydroxyls at both the 5' and 3' ends of the capped transcript). Such dual modifications may provide significant resistance to 5' exonucleases. Non-limiting examples of 5' cap structures that can be used with engineered polyribonucleotides include m 7 G(5')ppp(5')N('cap 0), m 7 G(5')ppp(5')N1mpNp('cap1) and m 7 G(5')ppp(5')N1mpN2mp('cap2).

[0085] The modifications to the modified mRNA of the present disclosure may generate a non-hydrolyzable cap structure that prevents cap removal, thereby increasing the half-life of the mRNA while promoting efficient translation. Since hydrolysis of the cap structure requires cleavage of the 5'-ppp-5' triphosphate bond, modified nucleotides may be used during the capping reaction. For example, vaccinia capping enzyme from New England Biolabs (Ipswich, MA) may be used with guanosine alpha-thiophosphate nucleotides according to the manufacturer's instructions to create phosphorothioate linkages in the 5'-ppp-5' cap. Additional modified guanosine nucleotides, such as alpha-methylphosphonate and selenophosphate nucleotides, may be used. Additional modifications include, but are not limited to, 2'-O-methylation of the ribose sugar of the 5'-end and / or pre-5'-end nucleotides of the mRNA on the 2'-hydroxyl group of the sugar ring. Multiple different 5' cap structures may be used to generate the 5' cap of a polyribonucleotide.

[0086] The modified mRNA may be post-transcriptionally capped. According to the present disclosure, the 5'-end cap may comprise an endogenous cap or a cap analog. According to the present disclosure, the 5'-end cap may comprise a guanine analog. Useful guanine analogs include, but are not limited to, inosine, N1-methyl-guanosine, 2'fluoro-guanosine, 7-deaza-guanosine, 8-oxo-guanosine, 2-amino-guanosine, LNA-guanosine and 2-azido-guanosine.

[0087] Furthermore, the nucleic acid construct(s), vector(s) or engineered polyribonucleotide(s) may contain one or more internal ribosome entry sites (IRES). An IRES sequence can initiate protein synthesis in the absence of a 5' cap structure. An IRES sequence may also be the only ribosome binding site or function as one of multiple ribosome binding sites of an mRNA. An engineered polyribonucleotide containing two or more functional ribosome binding sites may code for several peptides or polypeptides ("polycistronic or multicistronic polynucleotides") that are translated by the ribosome. The engineered polynucleotides described herein may contain at least one IRES sequence, two IRES sequences, three IRES sequences, four IRES sequences, five IRES sequences, six IRES sequences, seven IRES sequences, eight IRES sequences, nine IRES sequences, ten IRES sequences, or another suitable number is present in the engineered polyribonucleotide. Examples of IRES sequences that can be used in accordance with the present disclosure include, but are not limited to, those derived from tobacco etch virus (TEV), picornaviruses (e.g., FMDV), pest viruses (CFFV), polio viruses (PV), encephalomyocarditis viruses (EMCV), foot-and-mouth disease viruses (FMDV), hepatitis C viruses (HCV), classical swine fever viruses (CSFV), murine leukemia virus (MLV), simian immune deficiency viruses (SIV), or cricket paralysis viruses (CrPV).The IRES sequence can be derived from a commercially available vector, such as, for example, the IRES sequences available from Clontech™, GeneCopoeia™, or Sigma-Aldrich™. The IRES sequence can be, for example, at least 150 bases or base pairs, 200 bases or base pairs, 300 bases or base pairs, 400 bases or base pairs, 500 bases or base pairs, 600 bases or base pairs, 700 bases or base pairs, 800 bases or base pairs, 900 bases or base pairs, 1000 bases or base pairs, 2000 bases or base pairs, 3000 bases or base pairs, 4000 bases or base pairs, 5000 bases or base pairs, or 10000 bases or base pairs. An IRES sequence can be at most 10,000 bases or base pairs, 5,000 bases or base pairs, 4,000 bases or base pairs, 3,000 bases or base pairs, 2,000 bases or base pairs, 1,000 bases or base pairs, 900 bases or base pairs, 800 bases or base pairs, 700 bases or base pairs, 600 bases or base pairs, 500 bases or base pairs, 400 bases or base pairs, 300 bases or base pairs, 200 bases or base pairs, 100 bases or base pairs, 50 bases or base pairs, or 10 bases or base pairs.

[0088] The nucleic acid construct(s), vector(s) or engineered polyribonucleotide(s) of the present disclosure may contain one or more untranslated regions. The untranslated regions may contain any number of modified or unmodified nucleotides. The untranslated regions (UTRs) of a gene are transcribed into a polypeptide but are not translated. In some cases, the untranslated sequences can increase the stability of the nucleic acid molecule and the efficiency of translation. Regulatory features of the UTRs can be incorporated into the modified mRNA molecules of the present disclosure, for example, to increase the stability of the molecule. Certain features can also be incorporated to ensure controlled downregulation of transcripts in case they are misdirected to undesired organ sites. Some 5'UTRs play a role in translation initiation. 5'UTRs can contain a Kozak sequence that is involved in the process where ribosomes initiate the translation of many genes. The Kozak sequence can have the consensus GCC(R)CCAUGG, where R is a purine (adenine or guanine) located three bases upstream of the start codon (AUG). 5'UTR can form secondary structures involved in the binding of translation elongation factors. In some cases, the stability and protein production of the engineered polynucleotide molecules of the present disclosure can be increased by engineering features typically found in abundantly expressed genes of a particular target organ. For example, introduction of 5'UTR of liver-expressed mRNAs such as albumin, serum amyloid A, apolipoprotein A / B / E, transferrin, alpha-fetoprotein, erythropoietin or factor VIII can be used to increase the expression of engineered polynucleotides in the liver. Similarly, the use of 5'UTRs from muscle proteins (MyoD, myosin, myoglobin, myogenin, herculin) for endothelial cells (Tie-1, CD36), bone marrow cells (C / EBP, AML1, G-CSF, GM-CSF, CD1 lb, MSR, Fr-1, i-NOS), leukocytes (CD45, CD18), adipose tissue (CD36, GLUT4, ACRP30, adiponectin) and lung epithelial cells (SP-A / B / C / D) can be used to increase expression of an engineered polynucleotide in a desired cell or tissue.

[0089] Other non-UTR sequences can be incorporated into the 5' (or 3' UTR) UTR of the polyribonucleotide of the present disclosure. The 5' and / or 3' UTR can provide stability and / or translation efficiency of the polyribonucleotide. For example, an intron or a part of an intron sequence can be incorporated into the adjacent region of the engineered polyribonucleotide. The incorporation of an intron sequence can also increase the translation rate of the polyribonucleotide.

[0090] 3'UTRs may have stretches of adenosines and uridines embedded within them. These AU-rich signatures are particularly prevalent in genes with high turnover rates. AU-rich elements (AREs) can be divided into classes based on their sequence features and functional properties: Class I AREs contain several dispersed copies of the AUUUA motif within the U-rich region. C-Myc and MyoD contain Class I AREs. Class II AREs have two or more overlapping UUAUUUA(U / A)(U / A) nonamers. Molecules containing this type of ARE include GM-CSF and TNF-α. Class III AREs are less well defined. These U-rich regions do not contain AUUUA motifs. c-Jun and myogenin are two well-studied examples of this class. Proteins that bind to AREs can destabilize the messenger, while members of the ELAV family, such as HuR, can increase mRNA stability. HuR can bind to AREs of all three classes. A HuR-specific binding site can be engineered into the 3'UTR of a nucleic acid molecule, resulting in HuR binding and thus stabilization of the message in vivo.

[0091] Manipulation of AU-rich elements (AREs) in the 3'UTR can be used to modulate the stability of engineered polyribonucleotides. One or more copies of AREs can be engineered into the polyribonucleotide to modulate the stability of the polyribonucleotide. AREs can be identified, removed or mutated to increase stability in cells and thereby increase translation and production of the resulting protein. Transfection experiments can be performed in relevant cell lines with engineered polyribonucleotides and protein production can be assayed at various time points after transfection. For example, cells can be transfected with various ARE engineered molecules and the proteins produced can be assayed 6 hours, 12 hours, 24 hours, 48 ​​hours and 7 days after transfection using ELISA kits for the relevant proteins.

The non-translated region may contain a length of about 1 to about 10 bases or base pairs, about 10 to about 20 bases or base pairs, about 20 to about 50 bases or base pairs, about 50 to about 100 bases or base pairs, about 100 to about 500 bases or base pairs, about 500 to about 1000 bases or base pairs, about 1000 to about 2000 bases or base pairs, about 2000 to about 3000 bases or base pairs, about 3000 to about 4000 bases or base pairs, about 4000 to about 5000 bases or base pairs, about 5000 to about 6000 bases or base pairs, about 6000 to about 7000 bases or base pairs, about 7000 to about 8000 bases or base pairs, about 8000 to about 9000 bases or base pairs, or about 9000 to about 10000 bases or base pairs.

In some cases, an intron may contain, for example, at most 10,000 bases or base pairs, 5,000 bases or base pairs, 4,000 bases or base pairs, 3,000 bases or base pairs, 2,000 bases or base pairs, 1,000 bases or base pairs, 900 bases or base pairs, 800 bases or base pairs, 700 bases or base pairs, 600 bases or base pairs, 500 bases or base pairs, 400 bases or base pairs, 300 bases or base pairs, 200 bases or base pairs, or 100 bases or base pairs.

[0094] In some cases, a percentage of the nucleotides in the intron are modified.

In some cases, all of the nucleotides in the intron are modified.

[0095] The engineered polyribonucleotides of the present disclosure can include a polyA sequence. The polyA sequence (e.g., a polyA tail) can include any number of nucleotides. The polyA sequence may comprise a length of about 1 to about 10 bases or base pairs, about 10 to about 20 bases or base pairs, about 20 to about 50 bases or base pairs, about 50 to about 100 bases or base pairs, about 100 to about 500 bases or base pairs, about 500 to about 1000 bases or base pairs, about 1000 to about 2000 bases or base pairs, about 2000 to about 3000 bases or base pairs, about 3000 to about 4000 bases or base pairs, about 4000 to about 5000 bases or base pairs, about 5000 to about 6000 bases or base pairs, about 6000 to about 7000 bases or base pairs, about 7000 to about 8000 bases or base pairs, about 8000 to about 9000 bases or base pairs, or about 9000 to about 10000 bases or base pairs.

[0098] In some cases, a certain percentage of the nucleotides in the linker sequence are modified. For example, in some cases, less than 99%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5% or 1% of the nucleotides in the linker sequence are modified.

In some cases, the nucleic acid construct(s), vector(s) or engineered polyribonucleotide(s) include multiple stop codons. The stop codons may be selected from TGA, TAA and TAG.

DC40), coiled-coil domain containing 65 (CCDC65), dynein assembly factor 1 (DNAAF1), dynein assembly factor 2 (DNAAF2), dynein assembly factor 3 (DNAAF3), dynein assembly factor 5 (DNAAF5), axonemal dynein heavy chain 11 (DNAH11), axonemal dynein heavy chain 5 (DNAH5), axonemal dynein heavy chain 8 (DNAH8), axonemal dynein intermediate chain 2 (DNAI2), axonemal dynein light chain 1 (DNAL1), dynein regulatory complex body subunit 1 (DRC1), dyslexia susceptibility 1 candidate 1 (DYX1C1), axonemal central paired apparatus protein (HYDIN), leucine-rich repeat containing 6 (LRRC6), NME / NM23 family member 8 (NME8), oral-facial-digital syndrome 1 (OFD1), retinitis pigmentosa GTPase regulator (RPGR), radial spokehead 1 homolog (Chlamydomonas) (RSPH1), radial spokehead 4 homolog A (Chlamydomonas) (RSPH4A), radial spokehead 9 homolog The present invention provides a method of treating a subject having or at risk of having a primary ciliary dyskinesia, comprising administering to the subject a composition comprising a nucleic acid construct encoding (Chlamydomonas) (RSPH9), sperm associated antigen 1 (SPAG1) and zinc finger MYND type containing 10 (ZMYND10), or a variant of any of the foregoing, wherein the nucleic acid construct comprises codons that provide for heterologous or enhanced expression of (one or more) of the protein or variants thereof in cells of the subject, thereby treating a subject having or at risk of having a primary ciliary dyskinesia.

[0101] The encoded polypeptide is a polymer chain consisting of amino acid residue monomers linked together through amide bonds (peptide bonds). The amino acids can be l-optical isomers, d-optical isomers, or combinations thereof. The polypeptide can be a chain of at least three amino acids, a peptidomimetic, a protein, a recombinant protein, an antibody (monoclonal or polyclonal), an antigen, an epitope, an enzyme, a receptor, a vitamin, or a structural analog, or combinations thereof. Polyribonucleotides translated in the subject's body can provide a sufficient supply of a particular peptide or protein within a cell, tissue, or across many cells and tissues of the subject. In some cases, polyribonucleotides can be translated in vivo in the cytosol of a particular target cell type(s) or target tissue. In some cases, polyribonucleotides can be translated in vivo to provide a protein whose gene is associated with primary ciliopathies, a functional fragment thereof, or a protein that is at least 70% homologous to human DNAI1 or human DNAH5 protein. In some cases, polyribonucleotides can be translated in vivo in various non-target cell types or target tissue(s).Non-limiting examples of target or non-target cell include a) skin cells, such as keratinocytes, melanocytes, urothelial cells; b) nerve cells, such as neurons, Schwann cells, oligodendrocytes, astrocytes; c) liver cells, such as hepatocytes; d) intestinal cells, such as goblet cells, enterocytes; e) blood cells, such as lymphoid cells or bone marrow cells; and f) germ cells, such as sperm and eggs.Non-limiting examples of tissue include connective tissue, muscle tissue, nervous tissue, or epithelial tissue.In some cases, target cell or target tissue is cancerous cell, tissue, or organ.

[0102] The polynucleotide sequence may be derived from one or more species. For example, the polynucleotide sequence may be derived from a human (Homo sapiens), a mouse (e.g., Mus musculus), a rat (e.g., Rattus norvegicus or Rattus rattus), a microorganism (e.g., Chlamydomonas genus), or any other suitable organism. The polynucleotide sequence may be a chimeric combination of sequences from one or more species.

[0103] In some cases, the endogenous translation machinery can add post-translational modifications to the encoded peptide. Post-translational modifications can include the addition of hydrophobic groups that can target the polypeptide for membrane localization, the addition of cofactors for increased enzymatic activity, or the addition of smaller chemical groups. The encoded polypeptide can also be post-translationally modified to receive the addition of other peptide or protein moieties. For example, ubiquitination can result in the covalent attachment of ubiquitin to the encoded polypeptide, SUMOylation can result in the covalent attachment of SUMO (Small Ubiquitin-related MOdifier) ​​to the encoded polypeptide, and ISGylation can result in the covalent attachment of ISG15 (Interferon-Stimulate Gene 15).

[0104] In some cases, the encoded polypeptide may be post-translationally modified to undergo other types of structural changes. For example, the encoded polypeptide may be proteolytically cleaved, and one or more proteolytic fragments may regulate the activity of an intracellular pathway. The encoded polypeptide may be folded intracellularly. In some cases, the encoded polypeptide is folded in the presence of cofactors and molecular chaperones. The folded polypeptide may have secondary and tertiary structures. The folded polypeptide may combine with other folded peptides to form quaternary structures. The folded peptide may form functional multi-subunit complexes, such as antibody molecules with tetrameric quaternary structures. Various polypeptides that form antibody classes or isotypes may be expressed from polyribonucleotides.

[0105] The encoded polypeptide may be post-translationally modified to change the chemical nature of the encoded amino acid. For example, the encoded polypeptide may undergo post-translational citrullination or deimination, which is the conversion of arginine to citrulline. The encoded polypeptide may undergo post-translational deamidation, which is the conversion of glutamine to glutamic acid or asparagine to aspartic acid. The encoded polypeptide may undergo elimination, i.e., beta-elimination of phosphothreonine and phosphoserine, or the conversion of alkenes by dehydration of threonine and serine and decarboxylation of cysteine. The encoded peptide may also undergo carbamylation, which is the conversion of lysine to homocitrulline. The encoded peptide may also undergo racemization, such as racemization of proline by prolyl isomerase or racemization of serine by protein-serine epimerase. In some cases, the encoded peptide may undergo phosphorylation of serine, threonine and tyrosine.

[0106] The activity of a number of biomolecules can be regulated by the molecule encoded by polyribonucleotide.Non-limiting examples of molecules whose activity can be regulated by the encoded polynucleotide include amino acids, peptides, peptidomimetics, proteins, recombinant proteins, antibodies (monoclonal or polyclonal), antibody fragments, antigens, epitopes, carbohydrates, lipids, fatty acids, enzymes, natural products, nucleic acids (including DNA, RNA, nucleosides, nucleotides, structural analogs or combinations thereof), nutrients, receptors and vitamins.

[0107] Non-limiting examples of nucleotide sequences that may be part of the polynucleotides of the disclosure are disclosed in Table 3. [Table 3]

[0108] A polypeptide sequence can be engineered to have a desired altered codon usage, such as the altered codon usage of SEQ ID NO:15-16 or the altered codon usage of SEQ ID NO:17-18. For example, computer software can be used to generate the codon usage of SEQ ID NO:14. A polypeptide sequence can share a % homology with an amino acid sequence of an endogenous polypeptide. A polypeptide sequence can share at most 10% homology, at most 20% homology, at most 30% homology, at most 40% homology, at most 50% homology, at most 60% homology, at most 70% homology, at most 80% homology, at most 90% homology, or at most 99% homology with an amino acid sequence of an endogenous polypeptide. A variety of methods and software programs can be used to determine the homology between two or more peptides, such as NCBI BLAST, Clustal W, MAFFT, Clustal Omega, AlignMe, Praline, or another suitable method or algorithm.

[0109] immunogenicity Many drugs containing compositions that contain molecules of various sizes (polynucleotides, proteins or enzymes) can cause immune response when administered to a subject.In many cases, the immune system recognizes the composition as foreign and neutralizes its pharmaceutical effect.The polyribonucleotides and compositions of the present disclosure can have low immunogenicity or be non-immunogenic, thereby inducing little or no immune response by the immune system.

[0110] Immunogenicity can also be determined, for example, by measuring TNF-α and IL-8 levels and the ability to bind to TLR-3, TLR-7, TLR-8 and helicase RIG-1. To determine whether a polyribonucleotide has the desired low immunogenicity, the amount of one or more factors can be measured after administration of the polyribonucleotide to a subject. The immunogenicity of a polypeptide can be determined in relation to an increase in white blood cell count upon administration of the polypeptide to a subject. In some cases, upon administration of the composition to a subject, the subject exhibits an increase in the number of white blood cells of less than 90%, less than 80%, less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20%, or less than 10%. The polyribonucleotides of the present disclosure can induce minimal or no significant inflammatory or immunological responses.

[0111] Various methods can be used to determine the immunogenicity of polyribonucleotides. A very suitable method is the measurement of inflammatory markers in cells or simply the measurement of white blood cell counts in response to administration of polyribonucleotides. Such methods are described in the Examples. Cytokines associated with inflammation can be measured, such as TNF-α, IFN-α, IFN-β, IP-10, IL-8, IL-6 and / or IL-12. The expression of dendritic cell activation markers can also be used to assess immunogenicity. A further indicator of the immunological response can be the detection of binding to Toll-like receptors TLR-3, TLR-7 and TLR-8 and the helicase RIG-1.

[0112] The immunogenicity of polyribonucleotide can be measured as an overall increase in the level of inflammatory markers or white blood cell counts compared to the level before administration of polyribonucleotide.For example, unmodified or modified engineered polyribonucleotides can be administered to cells or subjects, and the secretion of inflammatory markers can be measured at a defined time interval in response to administration of polyribonucleotide.

[0113] composition In some cases, the disclosure provides a composition comprising a nucleic acid construct encoding axonemal dynein intermediate chain 1, the nucleic acid construct comprising a complementary deoxyribonucleic acid encoding axonemal dynein intermediate chain 1, the composition being formulated for administration to a subject. In some cases, the disclosure provides a composition comprising a nucleic acid construct encoding axonemal dynein intermediate chain 1, the nucleic acid construct comprising codons providing heterologous or enhanced expression of axonemal dynein intermediate chain 1 protein or a variant thereof in cells of a subject having or at risk of having primary ciliary dyskinesia. In some cases, the disclosure provides a composition comprising a nucleic acid construct encoding axonemal dynein intermediate chain 1, wherein less than 30% of the nucleic acid encoding axonemal dynein intermediate chain 1 is a nucleic acid analog such as pseudouridine or 1-methylpseudouridine. In some cases, the coding sequences of these constructs are engineered to have altered nucleotide usage in the protein coding regions to increase their stability.

[0114] In some cases, the codons of the construct are at least 70% homologous to mammalian or human axonemal dynein intermediate chain 1 protein. The construct may also include a 3' or 5' non-coding region adjacent to the codon sequence encoding a protein of interest, such as axonemal dynein intermediate chain 1, which enhances the expression of the protein in the cells of the subject. The 3' non-coding region adjacent to the codon may include a 3' cap-independent translation enhancer (3'-CITE) or a 3' stem-loop region derived from a nucleotide sequence of a histone protein or a 3' triple helix structure derived from a nucleotide sequence of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1). The 3' non-coding region adjacent to the codon may include a polyadenosine tail, where the number of adenosines in the polyadenosine tail improves the translation efficiency or half-life of the protein of interest, such as axonemal dynein intermediate chain 1 protein. In some cases, the length of the polyadenosine tail is at most 200 adenosines. In some cases, a percentage of the polyadenosine tail comprises a nucleic acid analog. Less than 50%, 40%, 30%, 20%, 10%, or 5% of the nucleic acid in the polyadenosine tail can be a nucleic acid analog.

[0115] When the composition includes a proportion of nucleotide analogs, the nucleotide analogs may be selected from the group consisting of pseudouridine, 1-methylpseudouridine, 2-thiouridine, 5-methyluridine, 5-methoxyuridine, 5-methylcytidine, 2'-amino-2'-deoxycytidine, and 2'-fluoro-2'-deoxycytidine. In some cases, the nucleic acid analog is pseudouridine or 1-methylpseudouridine. In some cases, the nucleic acid analog is 5-methoxyuridine.

[0116] In some cases, the composition comprises a nucleic acid and / or a nucleic acid analog encoding axonemal dynein intermediate chain 1. The composition may further comprise at least one additional nucleic acid construct. The at least one additional nucleic acid construct may be any of armadillo repeat containing 4 (ARMC4), chromosome 21 open reading frame 59 (C21orf59), coiled-coil domain containing 103 (CCDC103), coiled-coil domain containing 114 (CCDC114), coiled-coil domain containing 39 (CCDC39), coiled-coil domain containing 40 (CCDC40), coiled-coil domain containing 65 (CCDC65), dynein assembly factor 1 (DNAAF1), dynein assembly factor 2 (DNAAF2), dynein assembly factor 3 (DNAAF3), dynein assembly factor 5 (DNAAF5), axonemal dynein heavy chain 11 (DNAH11), axonemal dynein heavy chain 5 (DNAH5), axonemal dynein heavy chain 8 (DNAH8), axonemal The gene may encode a protein selected from the group consisting of dynein intermediate chain 2 (DNAI2), axonemal dynein light chain 1 (DNAL1), dynein regulatory complex subunit 1 (DRC1), dyslexia susceptibility 1 candidate 1 (DYX1C1), axonemal central paired apparatus protein (HYDIN), leucine-rich repeat containing 6 (LRRC6), NME / NM23 family member 8 (NME8), oral-facial-digital syndrome 1 (OFD1), retinitis pigmentosa GTPase regulator (RPGR), radial spokehead 1 homolog (Chlamydomonas) (RSPH1), radial spokehead 4 homolog A (Chlamydomonas) (RSPH4A), radial spokehead 9 homolog (Chlamydomonas) (RSPH9), sperm associated antigen 1 (SPAG1), and zinc finger MYND type containing 10 (ZMYND10).

[0117] The composition may include an engineered polyribonucleotide, vector, or nucleic acid construct. A "naked" polynucleotide composition may be successfully administered to a subject and taken up by the subject's cells without the aid of a carrier, stabilizer, diluent, dispersant, suspending agent, thickener, and / or excipient (Wolff et al. 1990, Science, 247, 1465-1468). However, in many cases, encapsulation of the polynucleotide with a formulation that can increase endocytic uptake can enhance the effectiveness of the compositions of the present disclosure. To overcome this challenge, in some cases, the composition includes a nucleic acid construct, vector, or isolated nucleic acid encoding axonemal dynein intermediate chain 1, the nucleic acid construct includes a complementary deoxyribonucleic acid encoding axonemal dynein intermediate chain 1, and the composition is formulated for administration to a subject.

[0118] Another technical problem underlying the delivery of polyribonucleotide to multicellular organisms is to identify compositions that provide highly efficient delivery of polyribonucleotides that are translated in cells or tissues of subjects.It is recognized that the administration of naked nucleic acid can be highly inefficient and does not provide a suitable approach for the administration of polynucleotides to multicellular organisms.

[0119] To solve this problem, compositions comprising engineered polyribonucleotides can be encapsulated or formulated with pharmaceutical carriers. The formulations can be, but are not limited to, nanoparticles, poly(lactic-co-glycolic acid) (PLGA) microspheres, lipidoids, lipoplexes, liposomes, polymers, carbohydrates (including monosaccharides), cationic lipids, fibrin gels, fibrin hydrogels, fibrin glues, fibrin sealants, fibrinogen, thrombin, rapid clearance lipid nanoparticles (reLNPs), and combinations thereof. The compositions comprising engineered polyribonucleotides disclosed herein can comprise from about 1% w / v to about 99% w / v of the carrier system. The amount of carrier present in the carrier system is based on several different factors or choices made by the formulator, such as the final concentration of polyribonucleotide and the amount of solubilizing agent. A variety of carriers have been shown to be useful in the delivery of various classes of therapeutic agents. Among these carriers, biodegradable nanoparticles formulated from the biocompatible polymers poly(D,L-lactide-co-glycolide) (PLGA) and polylactide (PLA) have shown potential for sustained intracellular delivery of various therapeutic agents.

[0120] The weight percent loading of the engineered polynucleotide in the composition can be at least 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 1%, 2%, 4%, 5%, 6%, 7%, 8%, 9% or 10%. The encapsulation efficiency of the modified mRNA in the PLGA microspheres can be at least 50%, at least 70%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99%.

[0121] The present disclosure describes nanoparticles, oligomers, polymers or lipidoids comprising oligo(alkyleneamine)s containing alternating non-identical alkyleneamine units, useful for delivering polynucleotides, in some cases engineered polyribonucleotides, to cells or tissues.The compositions disclosed herein can be stable for at least about 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 12 hours, 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 2 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks, 12 weeks, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months or 1 year. The formulations disclosed herein can be stable, for example, at temperatures of at least about 0° C., 5° C., 10° C., 15° C., 20° C., 25° C., 30° C., 35° C., 40° C., 45° C., 50° C., 60° C., 70° C., or 80° C. The compositions of the present disclosure can have a desired density. The density of the composition can improve the properties of the composition, such as the rheology of the composition.

[0122] Nanoparticles The present disclosure also provides nanoparticle-based formulations of nucleic acid constructs, engineered polyribonucleotides or vectors that can be transferred after administration to a subject. In some cases, administration is by pulmonary route, and the engineered polyribonucleotides can travel intact from the administration site to the systemic blood supply, either actively or passively, and then be deposited in various cells or tissues, such as, for example, the breast.For example, axonemal dynein intermediate chain 1 (DNAI1), armadillo repeat containing 4 (ARMC4), chromosome 21 open reading frame 59 (C21orf59), coiled-coil domain containing 103 (CCDC103), coiled-coil domain containing 114 (CCDC114), coiled-coil domain containing 39 (CCDC39), coiled-coil domain containing 40 (CCDC40), coiled-coil domain containing 65 (CCDC65), cyclin O (CCNO), Dynein assembly factor 1 (DNAAF1), dynein assembly factor 2 (DNAAF2), dynein assembly factor 3 (DNAAF3), dynein assembly factor 5 (DNAAF5), axonemal dynein heavy chain 11 (DNAH11), axonemal dynein heavy chain 5 (DNAH5), axonemal dynein heavy chain 6 (DNAH6), axonemal dynein heavy chain 8 (DNAH8), axonemal dynein intermediate chain 2 (DNAI2), axonemal dynein light chain 1 (DNAL1), dynein regulatory complex coalescence subunit 1 (DRC1), dyslexia susceptibility 1 candidate 1 (DYX1C1), growth arrest specific 8 (GAS8), axonemal central paired apparatus protein (HYDIN), leucine-rich repeat containing 6 (LRRC6), NME / NM23 family member 8 (NME8), oral-facial-digital syndrome 1 (OFD1), retinitis pigmentosa GTPase regulator (RPGR), radial spokehead 1 homolog (Chlamydomonas) (RSPH1), radial spokehead 4 homolog A (Chlamydomonas) This transfer of nanoparticles containing engineered polyribonucleotides encoding therapeutic proteins such as Rhodococcus aureus (R. domonas) (RSPH4A), radial spoke head 9 homolog (Chlamydomonas) (RSPH9), sperm associated antigen 1 (SPAG1) and zinc finger MYND type containing 10 (ZMYND10) or functional fragments thereof constitutes a non-invasive systemic delivery of active pharmaceutical ingredients beyond the lungs, resulting in the production of functional proteins in systemically accessible non-pulmonary cells or tissues.

[0123] The nanoparticles can be particles with a diameter of about 10 nanometers (nm) to 5000 nm, 10 nm to 1000 nm, or 60 nm to 500 nm, or 70 nm to 300 nm. In some examples, the nanoparticles have a diameter of about 60 nm to 225 nm. The nanoparticles can include an encapsulating agent (e.g., a coating) that encapsulates one or more polyribonucleotides, which can be engineered polyribonucleotides. The nanoparticles can include engineered and / or naturally occurring polyribonucleotides. The encapsulating agent can be a polymeric material, such as PEI or PEG.

Suitable nanoparticles may include one or more lipids in various ratios. For example, the compositions of the present invention may include C12-200:DOPE:cholesterol:DMG-PEG2000 in a ratio of 40:30:25:5 or HGT5001:DOPE:cholesterol:DMG-PEG2000 in a ratio of 40:20:35:5. Nanoparticles may include at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 lipids, or another suitable number of lipids.

[0125] The average size of the nanoparticle formulation may include modified mRNA from 60 nanometers (nm) to 225 nm. The polydispersity index PDI of the nanoparticle formulation including modified mRNA may be 0.03 to 0.15. The zeta potential of the nanoparticle formulation may be from -10 to +10 at pH 7.4. The formulation of modified mRNA may include fusogenic lipid, cholesterol and PEG lipid.

The lipid nanoparticles of the present disclosure may be formulated into a sealant, such as, but not limited to, fibrin sealant.

[0126] Oligo(alkyleneamine group) Encapsulation of polynucleotide with some formulations can increase the endocytosis uptake of the composition, but it is also recognized that the polynucleotide taken up by cells may not be effectively translated in the cell.Some formulations can be effectively used for plasmid DNA and / or siRNA delivery, but are not practical for use in polyribonucleotide delivery.The present disclosure provides formulations that can be used for effective delivery and translation of polyribonucleotide compositions to subjects.

[0127] The composition of the present disclosure can be designed to provide polyribonucleotides that are effectively translated in cells.The composition of the present disclosure comprises an arrangement of alkyleneamine units of alternating length in groups of 3 or more units, and comprises ethyleneamine units in the composition to transfect cells with any polynucleotide, such as engineered polyribonucleotides.The composition of the present disclosure can provide more effective delivery of polyribonucleotides to cells than a similar arrangement of alkyleneamine units of non-alternating length.

[0136] Non-limiting examples of alkenyl and alkenylene groups include straight-chain, branched-chain and cyclic alkenyl groups. The olefin(s) of the alkenyl group can be, for example, E, Z, cis, trans, terminal or exomethylene.

[0137] The oligo(alkyleneamine) structures of formulae (II), (III) and (IV) are characterized in that they can alternate between shorter (also referred to for purposes of illustration as "S") ethyleneamine units (i.e., a or b is 1) and longer (also referred to for purposes of illustration as "L") alkyleneamine units (i.e., the other of a or b is an integer from 2 to 4). Such an arrangement of protonatable units can provide advantages in terms of the suitability of the resulting group to provide a vehicle for intracellular delivery of polyribonucleotides.

[0138] The compositions of the present disclosure may include multiple oligo(alkyleneamine) groups of formula (II) as side or end groups: -NR 2 {CH2-(CH2) a -NR 3 -[CH2-(CH2) b -NR 4 ] p} m -[CH2-(CH2) a -NR 5 ] n -R 6 (II) [wherein the variables a, b, p, m, n and R 2 ~R 6 is defined independently for each group of formula (II) in multiple such groups as follows: a is 1 and b is an integer from 2 to 4, or a is an integer from 2 to 4 and b is 1; p is 1 or 2; m is 1 or 2; n is 0 or 1, and m+n is 2 or more; and R 2 ~R 5 are, independently of each other, hydrogen; -CH-CH(OH)-R 7 , -CH(R 7 )-CH2-OH, -CH2-CH2-(C=O)-OR 7 , -CH2-CH2-(C=O)-NH-R 7 or -CH2-R 7 Group (where R 7is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond; a protecting group for an amino group; -C(NH)-NH2-; and a poly(ethylene glycol) chain; R 6 is hydrogen; -CH2-CH(OH)-R 7 , -CH(R 7 )-CH2-OH, -CH2-CH2-(C=O)-OR 7 , -CH2-CH2-(C=O)-NH-R 7 or -CH2-R 7 Group (where R 7 is selected from C3-C16 alkyl or C3-C16 alkenyl having one C-C double bond; a protecting group for an amino group; -C(NH)-NH; a poly(ethylene glycol) chain; and a receptor ligand.

[0139] In some cases, R 2 ~R 5 is hydrogen, and R 6 is selected from hydrogen, a protecting group for an amino group, -C(NH)-NH2, and a poly(ethylene glycol) chain. 2 ~R 6 is hydrogen. In some cases, R 7 is selected from C8-C18 alkyl or C8-C18 alkenyl having one CC double bond, or C8-C12 alkyl or C8-C12 alkenyl having one CC double bond, or C10-C12 alkyl or C10-C12 alkenyl having one CC double bond. The compositions of the present disclosure may include one or more alkylene groups of formulae (II)-(IV).

[0140] In some cases, oligomers or polymers that can be used in compositions according to the present disclosure include multiple oligo(alkyleneamine) groups of formula (III) as repeating units: NR 2 {CH2-(CH2) a -NR 3 -[CH2-(CH2) b -NR 4 ]p} m -[CH2-(CH2) a -NR 5 ] n -(III) [wherein the variables a, b, p, m, n and R 2 ~R 5 is defined independently for each group of formula (III) in multiple such groups as follows: a is 1 and b is an integer from 2 to 4, or a is an integer from 2 to 4 and b is 1; p is 1 or 2; m is 1 or 2; n is 0 or 1, and m+n is 2 or more; and R 2 ~R 5 are, independently of each other, hydrogen; -CH-CH(OH)-R 7 , -CH(R 7 )-CH2-OH, -CH2-CH2-(C=O)-OR 7 , -CH2-CH2-(C=O)-NH-R 7 , -CH2-R 7 or a -CH2- group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond; a protecting group for an amino group; -C(NH)-NH2; a poly(ethylene glycol) chain; and an endosomal escape effector and receptor ligand.

Alternatively, R 7 may be selected from C10-C12 alkyl or C10-C12 alkenyl having one CC.

[0141] One or more of the nitrogen atoms shown in formula (III) may be protonated to provide a cationic group of formula (III).

[0142] Oligomers or polymers containing multiple groups of formula (III) as repeat units may further contain one or more oligo(alkyleneamine) groups of formula (II) as side chains and / or terminal groups.

[0143] In the case of multiple groups of formula (III) as repeat units, two, three or more groups of formula (III) can be included in an oligomer or polymer. Generally, materials containing 2-9 repeat units are referred to herein as oligomers, and materials containing 10 or more repeat units are referred to as polymers. Thus, in a polymer containing multiple groups of formula (III) as repeat units, there can be 10 or more groups of formula (III). It is understood that the groups of formula (III) can have the same structure within a polymer or oligomer, or can have two or more different structures within formula (III). In some cases, oligomers or polymers containing multiple groups of formula (III) as repeat units can be provided in the form of a library of sequenced polymers prepared in a controlled stepwise polymerization from different groups of formula (III).

[0144] According to the above formulas (II) and (III), the alkyleneamine units may be repeated once in alternating chains to obtain oligo(alkyleneamine) moieties of the -SLLS- or -LSSL-type, where S represents the shorter alkyleneamine unit and L represents the longer alkyleneamine unit. In some cases, the groups of formulas (II) and (III) are non-repeating, i.e., p is 1, so that the shorter or longer units do not appear in pairs. The group of formula (II) may be an oligo(alkyleneamine) group of formula (IIa) and the group of formula (III) may be an oligo(alkyleneamine) group of formula (IIIa): -NR 2 {CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR 4} m -[CH2-(CH2) a-NR 5 ] n -R 6 (IIa) [Wherein, a, b, m, n and R 2 ~R 6 is defined as formula (II), and one or more of the nitrogen atoms shown in formula (IIa) may be protonated to provide a cationic oligomeric or polymeric structure; -NR 2 {CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR 4} m -[CH2-(CH2) a -NR 5 ] n -(IIIa) [Wherein, a, b, m, n and R 2 ~R 5 is defined as formula (III), and one or more of the nitrogen atoms shown in formula (IIa) may be protonated to provide a cationic oligomeric or polymeric structure.

[0145] Further, in some cases, the oligo(alkyleneamine) groups of formulas (II) and (III) can have an n of 1. In some cases, m is 1 and n is 1. In some cases, the group of formula (II) is an oligo(alkyleneamine) group of formula (IIb) and the group of formula (III) is an oligo(alkyleneamine) group of formula (IIIb): -NR 2 -CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR 4 -CH2-(CH2) a -(NR 5 )-R 6 (IIb) [Wherein, a, b and R 2 ~R 6 is defined as formula (II), and one or more of the nitrogen atoms shown in formula (IIb) may be protonated to provide a cationic oligomeric or polymeric structure; -NR2 -CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR 4 -CH2-(CH2) a -NR 5 -(IIIb) [Wherein, a, b and R 2 ~R 5 is defined as formula (III), and one or more of the nitrogen atoms shown in formula (IIIb) may be protonated to provide a cationic oligomeric or polymeric structure.

[0146] With respect to the length of the alkyleneamine units in the oligo(alkyleneamine) groups of formulae (II), (IIa), (IIb) and (III), (IIIa), (IIIb), one of the alternating units can be an ethyleneamine unit (i.e., either a or b is 1). The other alternating unit can be a propyleneamine unit, a butyleneamine unit or a pentyleneamine unit (i.e., the other of a or b can be an integer from 2 to 4). In some cases, the other of a or b can be 2 or 3, and in some cases, a is 1 and b is 2, or a is 2 and b is 1. In some cases, an oligo(alkyleneamine) group of formula (IIc) is used in place of or in addition to group (II), and / or an oligo(alkyleneamine) group of formula (IIIc) is used in place of or in addition to group (III). The formulae of groups (IIc) and (IIIc) are as follows: -NR 2 -CH2-CH2-NR 3 -CH2-CH2-CH2-NR 4 -CH2-CH2-NR 5 -R 6 (IIc) [In the formula, R 2 ~R 6 is as defined in formula (II), R 2 ~R 6 is hydrogen, and one or more of the nitrogen atoms shown in formula (IIc) may be protonated to provide a cationic oligomeric or polymeric structure; -NR 2 -CH2-CH2-NR 3 -CH2-CH2-CH2-NR 4 -CH2-CH2-NR 5 -(IIIc) [In the formula, R 2 ~R 5 is as defined in formula (III), and one or more of the nitrogen atoms shown in formula (IIIc) may be protonated to provide a cationic oligomeric or polymeric structure.

[0147] In some cases, R in formulas (II), (IIa), (IIb) and (IIc) 2 ~R 6 or R in formulae (III), (IIIa), (IIIb) and (IIIc) 2 ~R 5 can be a protecting group for an amino group. Non-limiting examples of protecting groups include t-butoxycarbonyl (Boc), 9-fluorenylmethoxycarbonyl (Fmoc) or carbobenzyloxy (Cbz).

[0148] In some cases, R in formulas (II), (IIa), (IIb) and (IIIc) 1 ~R 6 or R in formulae (III), (IIIa), (IIIb) and (IIIc) 2 ~R 5The groups are receptor ligands such as those described by Philipp and Wagner in "Gene and Cell Therapy-Therapeutic Mechanisms and Strategy", 3rd Edition, Chapter 15, CRC Press, Taylor & Francis Group LLC, Boca Raton 2009. Examples of receptor ligands that target lung tissue are described in Pfeifer et al. 2010, Ther. Deliv. 1(1):133-48. Receptor ligands can include synthetic cyclic or linear peptides, such as those derived from screening peptide libraries for binding to specific cell surface structures or specific cell types, cyclic or linear RGD peptides, synthetic or natural carbohydrates such as sialic acid, galactose or mannose, or synthetic ligands derived, for example, from reacting peptides with carbohydrates, antibodies that specifically recognize cell surface structures, folic acid, epidermal growth factor and peptides derived therefrom, transferrin, anti-transferrin receptor antibodies, nanobodies and antibody fragments, approved drugs that can bind to cell surface molecules (e.g., cell surface receptors), and the like.

[0149] R in formulas (II), (IIa), (IIb) and (IIc) 1 ~R 6 or R in formulae (III), (IIIa), (IIIb) and (IIIc) 2 ~R 5 So long as any of the groups is a poly(ethylene glycol) chain, the molecular weight of the poly(ethylene glycol) chain can be from about 100 g / mol to 20,000 g / mol, from about 1,000 g / mol to 10,000 g / mol, or from about 1,000 g / mol to 5,000 g / mol.

[0150] In some cases, the group (II) can be an oligo(alkyleneamine) group of formula (IId): -NH-CH2-CH2-NH-CH2-CH2-CH2-NH-CH2-CH2-NH-H(IId) [wherein one or more of the nitrogen atoms shown in formula (IId) may be protonated to provide a cationic polymer or dendrimer structure.] In some cases, group (III) is an oligo(alkyleneamine) group of formula (IIId): -NH-CH2-CH2-NH-CH2-CH2-CH2-NH-CH2-CH2-NH-(IIId) [wherein one or more of the nitrogen atoms shown in formula (IIId) may be protonated to provide a cationic polymer or dendrimer structure].

[0151] Lipidoids The engineered polyribonucleotides can be encapsulated in lipidoid formulations. The lipidoid formulations can be any substance with lipid properties, such as fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, triglycerides, phospholipids, etc. For example, the lipid or lipidoid formulation can include lipids such as cholesterol, DOPE, DOPC or DSPC, which are referred to in the scientific literature as helper lipids, and / or PEGylated lipids or any other lipids useful for preparing lipoplexes. The formulations containing the engineered polyribonucleotides can be nanoparticles that can include at least one lipid. The lipidoid formulations can be lipid nanoparticles. The lipids can be selected from, but are not limited to, DOPE, DOPC, DSPC, cholesterol, DLin-DMA, DLin-K-DMA, 98N12-5, C12-200, DLin-MC3-DMA, DLin-KC2-DMA, DODMA, PLGA, PEG, PEG-DMG and PEGylated lipids. In another embodiment, the lipid can be a cationic lipid, such as, but not limited to, DLin-DMA, DLin-D-DMA, DLin-MC3-DMA, DLin-KC2-DMA, and DODMA.

[0152] A composition comprising a lipidoid may be about 40-60% lipidoid, about 40-60% cholesterol, and about 5-20% PEG-lipid (weight percent based on the total weight of the composition). A composition comprising a lipidoid may be about 50-60% lipidoid, about 40-50% cholesterol, and about 5-10% PEG-lipid. A composition comprising a lipidoid may be about 50-75% lipidoid, about 20-40% cholesterol, and about 1-10% PEG-lipid. A composition comprising a lipidoid may be about 60-70% lipidoid, about 25-35% cholesterol, and about 5-10% PEG-lipid. The compositions can be provided using techniques described, for example, in Akinc et al, 2007, Nat Biotech, 26, 561-569; Akinc et al, 2009, Mol Ther, 17, 872-9; Love et al, 2010, PNAS, 107, 1864-9; U.S. Patent No. 8,450,298, International Publication No. O2006 / 138380. The RNA / lipidoid complexes can form particles useful for delivery of RNA, such as single-stranded RNA or mRNA, to cells.

[0153] The composition of the disclosure may be an engineered polyribonucleotide encapsulated by a lipidoid of formula (IV): R 1 -NR 2 {CH2-(CH2) a -NR 3 -[CH2-(CH2) b -NR 4 ] p} m -[CH2-(CH2) a -NR 5 ] n -R 6 (IV) [wherein the variables a, b, p, m, n and R1-R6 are defined as follows: a is 1 and b is an integer from 2 to 4, or a is an integer from 2 to 4 and b is 1; p is 1 or 2; m is 1 or 2; n is 0 or 1, and m+n is 2 or more; and R 1 ~R 6 are, independently of each other, hydrogen; -CH-CH(OH)-R 7 , -CH(R 7 )-CH2-OH, -CH2-CH2-(C=O)-OR 7 , -CH2-CH2-(C=O)-NH-R 7 or -CH2-R 7 Group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond; a protecting group for an amino group; -C(NH)-NH2; a poly(ethylene glycol) chain; and a receptor ligand; provided that R 1 ~R 6 At least two of the residues are -CH-CH(OH)-R 7 , -CH(R 7 )-CH2-OH, -CH2-CH2-(C=O)-OR 7 , -CH2-CH2-(C=O)-NH-R 7 or -CH2-R 7 Group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one CC double bond).

[0154] In some cases, R 1 ~R 6 are independently hydrogen; -CH2-C(OH)HR 7 or -CH(R 7 )-CH2-OH (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond; a protecting group for an amino group; and a poly(ethylene glycol) chain; provided that R 1 ~R 6 At least two of the residues are -CH2-C(OH)HR 7 or -CH(R 7 )-CH2-OH group (where R 7is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond. 1 ~R 6 are independently hydrogen; and -CH-CH(OH)-R 7 or -CH(R 7 )-CH2-OH group (where R 7 is selected from C3-C16 alkyl or C3-C16 alkenyl having one C-C double bond; 1 ~R 6 At least two of the residues are -CH-CH(OH)-R 7 or -CH(R 7 )-CH2-OH group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond. 1 and R 6 are independently hydrogen; and -CH-CH(OH)-R 7 or -CH(R 7 )-CH2-OH group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond; and R 2 ~R 5 are all -CH2-CH(OH)-R 7 or -CH(R 7 )-CH2-OH group (where R 7 is selected from C3-C18 alkyl or C3-C18 alkenyl having one C-C double bond. 7 is selected from C8-C16 alkyl or C8-C18 alkenyl having one CC double bond, or C8-C12 alkyl or C8-C12 alkenyl having one CC double bond, or C10-C12 alkyl or C10-C12 alkenyl having one CC double bond.

[0155] One or more of the nitrogen atoms shown in formula (IV) may be protonated to provide a cationic lipidoid of formula (IV).

[0156] According to formula (IV) above, the alkyleneamine unit may be repeated once in alternating chains to obtain oligo(alkyleneamine) moieties of the -SLLS- or -LSSL-type, where S represents the shorter alkyleneamine unit and L represents the longer alkyleneamine unit. In some cases, the lipidoid of formula (IV) is one in which the repetition does not occur, i.e. p is 1, so that the shorter or longer units do not appear in pairs. The lipidoid of formula (IV) may be a lipidoid of (IVa): R 1 -NR 2 {CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR} m -[CH2-(CH2) a -NR 5 ] n -R 6 (IVa) [Wherein, a, b, m, n and R 1 ~R 6 is defined as formula (IV), and one or more of the nitrogen atoms shown in formula (IVa) may be protonated to provide a cationic lipidoid; In some cases, the lipidoid is of formula (IV). In some cases, "n" is 1 in the lipidoid of formula (IV). In some cases, "m" is 1 and n is 1 in the lipidoid of formula (IV). In some cases, the lipidoid of formula (IV) is of formula (IVb): R-NR 2 -CH2-(CH2) a -NR 3 -CH2-(CH2) b -NR 4 -CH2-(CH2) a -NR 5 -R 6 (IVb) [Wherein, a, b and R 1~R 6 is defined as formula (IV), and one or more of the nitrogen atoms shown in formula (IVb) may be protonated to provide a cationic lipidoid.

[0157] With respect to the length of the alkyleneamine units in the lipidoids of formula (IV), (IVa) and (IVb), it is understood that one of the alternating units must be an ethyleneamine unit (i.e., either a or b is 1). The other alternating unit can be a propyleneamine unit, a butyleneamine unit, a pentyleneamine unit, or another suitable unit (i.e., the other of a or b is an integer from 2 to 4). In some cases, the lipidoid of formula (IV) is a lipidoid of formula (IVc): R 1 -NR 2 -CH2-CH2-NR 3 -CH2-CH2-CH2-NR 4 -CH2-CH2-NR 5 -R S (IVc) [In the formula, R 1 ~R 6 is as defined in formula (IV), and one or more of the nitrogen atoms shown in formula (IVc) may be protonated to provide a cationic lipidoid.

[0158] In some cases, R in formulas (IV), (IVa), (IVb) and (IVc) 1 ~R 6 is a protecting group for an amino group. Non-limiting examples of protecting groups include t-butoxycarbonyl (Boc), 9-fluorenylmethoxycarbonyl (Fmoc) or carbobenzyloxy (Cbz).

Examples of receptor ligands that target lung tissue are described in Pfeifer et al. 2010, Ther. Deliv. 1(1):133-48. Receptor ligands can include synthetic cyclic or linear peptides, such as those derived from screening peptide libraries for binding to specific cell surface structures or specific cell types, cyclic or linear RGD peptides, synthetic or natural carbohydrates such as sialic acid, galactose or mannose, or synthetic ligands derived, for example, from reacting peptides with carbohydrates, antibodies that specifically recognize cell surface structures, folate, epidermal growth factor and peptides derived therefrom, transferrin, anti-transferrin receptor antibodies, nanobodies and antibody fragments, approved drugs that can bind to cell surface molecules (e.g., cell surface receptors), and the like.

[0160] R in formulae (IV), (IVa), (IVb) and (IVc) 1 ~R 6 To the extent that the group is a poly(ethylene glycol) chain, the molecular weight of the poly(ethylene glycol) chain can be about 100 g / mol to 20,000 g / mol, about 1,000 g / mol to 10,000 g / mol, or about 1,000 g / mol to 5,000 g / mol. In some cases, the molecular weight of the PEG chain can provide a composition with a desired density.

[0161] A plurality of lipidoid molecules can be combined with the engineered polyribonucleotide. For example, the composition can include one engineered polyribonucleotide to 100 lipidoid molecules, one engineered polyribonucleotide to 1,000 lipidoid molecules, 10 engineered polyribonucleotide to 1,000 lipidoid molecules, or 100 engineered polyribonucleotide to 10,000 lipidoid molecules. The complex of the engineered polyribonucleotide and lipidoid can form a particle. The diameter of the particle can be, for example, in the range of 10 nanometers to 1200 nanometers. In some cases, the diameter of the particle is in the range of 10 nanometers to 500 nanometers. In some cases, the diameter of the particle is in the range of 20 nanometers to 150 nanometers.

[0162] Administration to subjects Methods for administering a polynucleotide (e.g., a polyribonucleotide, a nucleic acid construct, or a vector) to a subject are further described herein. The polyribonucleotide can be provided to the subject via a delivery agent, such as a particle or capsule having an encapsulating agent that encapsulates the polyribonucleotide. The delivery agent can be a therapeutic agent. The subject can be a human, such as a human suffering from a disease or condition (e.g., primary ciliary dysfunction (PCD), Kartagener's syndrome, or cancer). The delivery agent can be administered to the subject at a predetermined dosage (e.g., self-administered or administered by a third party, such as a healthcare provider), and the dosage can be increased over time, decreased over time, or maintained constant. The dosage can be altered based on the progression or regression of a disease in the subject, such as a rare disease or cancer.

[0163] The polyribonucleotide of the present disclosure can be formulated with one or more pharma- ceutically acceptable carriers to be administered to a subject.In some cases, the polyribonucleotide can be formulated for targeted delivery to a target cell or cell population.In some cases, the polyribonucleotide can be formulated for non-targeted delivery to a cell or cell population.The polypeptide product encoded by the polyribonucleotide is then transcribed and accumulates in the recipient cell.

[0164] The composition may be a combination of any of the engineered polyribonucleotides described herein with other chemical components, such as carriers, stabilizers, diluents, dispersants, suspending agents, thickeners and / or excipients.

[0165] The composition can be administered locally or systemically, for example by direct injection of the compound into an organ, and can be administered as a depot or sustained release formulation.The pharmaceutical composition can be provided in the form of a rapid release formulation, a sustained release formulation, or an intermediate release formulation.The rapid release formulation can provide immediate release.The sustained release formulation can provide controlled release or delayed sustained release.

[0166] For administration by inhalation, active compound can be in the form of aerosol, mist, steam, spray or powder.The pharmaceutical composition is conveniently delivered in the form of aerosol spray from pressurized pack or nebulizer using suitable propellant, for example, dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas.For pressurized aerosol, dosage unit can be determined by providing a valve to deliver a metered amount.For example, capsules and cartridges of gelatin for use in inhaler or insufflator can be formulated with powder mixture of compound and suitable powder base, for example, lactose or starch.

The composition can be administered by injecting the formulation into any part of the eye, including the anterior chamber, posterior chamber, vitreous cavity (intravitreal), retinal cavity proper and / or subretinal space. The composition can also be delivered by non-invasive methods. Non-invasive methods of administering the formulation can include using a needleless injection device.

The transfection efficiency of the composition can be increased by adding a carrier such as a cell-penetrating peptide or cationic coating to the outer layer of the composition. The transfection efficiency of the composition can be adjusted by the density of the composition.

[0176] [Example] [Example 1] Preparation of DNAI1 RNA-containing This experiment demonstrates the generation of a DNAI1 complementary deoxyribonucleic acid construct.

[0177] Methods: DNAI1 was synthesized with GenScript. pUC57 / DNAI1 was digested with HindIII and EcoRI HF restriction enzymes. Furthermore, the digested pVAX120 vector and DNAI1 cDNA were gel purified and ligated (the ORF of DNAI1 is codon optimized). Standard in vitro translation procedures were used for RNA generation utilizing unmodified nucleotides. Capping reactions were performed using the Vaccinia Virus Capping System and Cap 2'-O-Methyltransferase. Figure 1 is an agarose gel showing the generation of capped and uncapped DNAI1 RNA. Note that in this experiment, DNAI1 cDNA was ligated into pVAX120 to provide a construct containing a poly(A) tail.

[0178] [Example 2] Expression of DNAI ribonucleic acid in mammalian cells This experiment demonstrates the expression (translation) of DNAI1 in HEK-293 cells. Figure 2 is a Western blot showing the translation of DNAI1 mRNA in 293 cells 6, 24 and 48 hours after transfection. For this experiment, 5 × 10 5 293 cells / well were transfected with 2.5μg DNAI1 RNA using 3.75μl messenger max transfection reagent. 6, 24 and 48 hours after transfection, cells were scraped from the wells, pelleted and pellets were dissolved in RIPA buffer. The blot was probed with anti-DNAI1 ab166912 from Abcam. C-terminal FLAG-tagged DNAI1 plasmid DNA was transfected as a control and the difference in MW between the plasmid and mRNA is likely due to the FLAG tag in the pENTRY vector.

[0179] [Example 3] Formulation of a composition comprising engineered polyribonucleotides for the treatment of a human subject suffering from primary ciliary dyskinesia.

[0180] The composition is formulated as follows: A nucleic acid construct encoding the DNAI1 gene sequence, NCBI reference sequence: NM_012144, is prepared as described in Example 1. Branched polyethyleneimine is purchased from Sigma Aldrich™. Linear in vivo jetPEI® (polyethyleneimine) is purchased from Polyplus transfection® (Illkirch, France) and used without further purification. Following the manufacturer's protocol, jetPEI is diluted to 5% glucose (final concentration) using a sterile 10% glucose solution provided by the manufacturer and HPLC grade water purchased from Sigma-Aldrich (St. Louis, MO). After diluting the nucleic acid construct to 5% glucose (final concentration), the RNA and jetPEI solutions are combined / mixed in a 1:1 ratio, resulting in a final N / P ratio of 8. The mRNA is then administered by intranasal drops. Alternatively, the nucleic acid construct can be formulated for administration by spraying or sniffing the lipoplex formulation.

[0181] [Example 4] Effect of post-transcriptional polyadenylation reaction time on RNA quality The effect of post-transcriptional polyadenylation reaction time on RNA quality was tested. Polyadenylation reaction times after in vitro transcription (IVT) are typically 60-90 min long and usually provide a polyA length of at most about ~200 As. Because mRNA is susceptible to hydrolysis, it is often degraded over time during the post-transcriptional polyadenylation reaction. To maintain the optimal length of the DNAI1 polyA tail and maximize RNA quality, we constructed a nucleic acid construct encoding axonemal dynein intermediate chain 1 protein or its variants with a polyA tail already included in the template.

[0182] The nucleic acid constructs encoding the DNAI1 gene sequence with and without the polyA sequence used to generate DNAI1 mRNA are outlined below: [Table 4]

[0183] Figure 3 shows fragment analyzer data to determine the length of DNAI1 mRNA generated from DNAI1-pCMV6Entry plasmid that was post-transcriptionally polyadenylated at 0-60 min reaction times. This demonstrates that transcript length increases at longer polyadenylation reaction times. Figure 4 shows fragment analyzer data to examine the quality of these DNAI1 mRNA that were post-transcriptionally polyadenylated at 0-60 min reaction times. These results indicate that the RNA undergoes degradation as the polyadenylation reaction proceeds, as shown by the decrease in peak % and increase in pre-peak smear % at longer reaction times. Figure 5 shows the length of the polyA sequence in the DNAI1-pVAX plasmid template as determined by 8% PAGE.

[0184] [Example 5] In vitro RNA production and quality control To compare the effect of incorporating various ratios of specific chemically modified nucleotides on translation efficiency in different cell types and immunogenicity, the following experiments were performed.

[0185] The experiments included: 1) in vitro transcription of the nucleic acid construct; 2) in vitro capping of the nucleic acid construct; 3) analysis of the integrity of the transcribed RNA; 4) immunodot blot assay of dsRNA; and 5) analysis of the nucleotide composition of the transcribed RNA. A general protocol for in vitro transcription (IVT) and capping of RNA was followed with some modifications. The IVT reaction of the nucleic acid construct encoding the DNAI1 gene was carried out at 37°C for 6 hours in the presence of 20 mM MgCl2 and 7.5 mM of each ribonucleotide.

[0186] Table 5 shows the various specific chemically modified nucleotides that were in vitro transcribed from axonemal dynein intermediate chain 1-encoding nucleic acid constructs. [Table 5]

[0187] result: UV measurement [Table 6]

[0188] Template Poly(A) Long-Fragment Analyzer Analysis of the length of the poly(A) tail of the DNAI1 nucleic acid construct (SEQ ID NO: 5) used as a template for in vitro transcription showed that the number of A residues was maintained compared to the original cloning vector (pVAX-A120). The initial vector contained 120 adenosine nucleotides, and a band of 100-150 bp was detected in this nucleic acid construct (Figure 5). The template was digested with EcoRI and Not I to remove the poly(A) fragment: 12 non-poly(A) nucleotides are expected to be part of the fragment. G*AATTCtgcag-poly(A)-GC*GGCCGC=12 nucleotides + poly(A) in the EcoRI / NotI generated fragment.

[0189] RNA Smear Analysis - Fragment Analyzer For all transcripts generated for DNAI1, a peak of approximately 2,000 nucleotides was detected. Evaluation of the in vitro generated transcripts on the Fragment Analyzer showed that the capped transcripts maintained good integrity: limited detection of smear content (indicative of RNA degradation and / or hydrolysis) was observed in repeat experiments. Briefly, 2 μL of sample at 200 ng / μL was analyzed on the Fragment Analyzer (DNF-471 Standard Sensitivity RNA Analysis Kit (15 nucleotide lower marker)). Data analysis was performed using PROSize 2.0 software. Sizing accuracy is approximately within ±5%, sizing reproducibility is approximately within 5%CV, quantification accuracy is approximately within ±20%, and quantification reproducibility is approximately 10%CV. Figure 6 shows the Fragment Analyzer data for in vitro reactions containing only standard nucleotides, i.e., adenosine 5'-triphosphate, guanosine 5'-triphosphate, cytidine 5'-triphosphate, and uridine 5'-triphosphate. Figure 7 shows the fragment analyzer data for in vitro reactions containing a 50% / 50% mixture of pseudouridine and uridine 5'-triphosphate. Figure 8 shows the fragment analyzer data for in vitro reactions containing 100% pseudouridine 5'-triphosphate. Figure 9 shows the fragment analyzer data for in vitro reactions containing 100% 1-methyl-pseudouridine 5'-triphosphate. Table 7 summarizes the results of the RNA smear analysis: [Table 7]

[0190] The double-stranded RNA content detected by dot blot showed reactivity with the J2 antibody. Figure 10 shows the double-stranded RNA content detected by dot blot analysis of in vitro transcribed RNA from a nucleic acid construct encoding axonemal dynein intermediate chain 1, as well as the double-stranded RNA content of transcribed DNAI1 constructs with various specific modifications as shown in Table 5.

[0191] Nucleoside composition analysis Tables 8-10 show nucleotide compositional analysis of in vitro transcribed RNA from a nucleic acid construct encoding axonemal dynein intermediate chain 1. The various specific nucleotide modifications are shown in Table 5. Figures 11-13 show the corresponding HPLC chromatograms of individual ribonucleotides obtained after nuclease digestion of the transcript and subsequent dephosphorylation.

[0192] Table 8 shows the nucleotide composition analysis of in vitro transcribed RNA from a nucleic acid construct encoding transcribed axonemal dynein intermediate chain 1 with unmodified nucleotides. Figure 11 shows the corresponding HPLC chromatogram. [Table 8]

[0193] Table 9 shows the nucleotide composition analysis of in vitro transcribed RNA from a nucleic acid construct encoding transcribed axonemal dynein intermediate chain 1 with 50% pseudouridine. Figure 12 shows the corresponding HPLC chromatogram. The retention time of the hydrophobic 1-methyl-pseudouridine using identical reversed-phase HPLC conditions averages about 9.5 minutes, well separated from all other ribonucleotides examined (data not shown). [Table 9]

[0194] Table 10 shows the nucleotide composition analysis of in vitro transcribed RNA from a nucleic acid construct encoding transcribed axonemal dynein intermediate chain 1 with 100% pseudouridine. Figure 13 shows the corresponding HPLC chromatogram. [Table 10]

[0195] [Example 6] Translation Efficiency The translation efficiency of the above DNAI1 transcripts was evaluated in three cell lines: 1) HEK-293 human embryonic kidney cells; 2) A549 adenocarcinoma human alveolar basal epithelial cells; and 3) MLE-15 mouse lung epithelial cells. Each cell line was transfected in triplicate with each DNAI1 transcript, and the resulting cell extracts were analyzed for DNAI1 protein expression by Western blot. Briefly, 1 × 10 cells per well were transfected with each DNAI1 transcript. 6 (HEK-293, MLE-15) or 2 × 10 6 (A549) cells were plated and transfected 18 hours later in 6-well plates. Cells were transfected with approximately 100 ng of each RNA using MessengerMax transfection reagent at an RNA:MessengerMax ratio of 1:37.5. Cells were harvested 6 hours after transfection and whole cell extracts were prepared in RIPA buffer (50 mM Tris-HCl pH 8, 150 mM NaCl, 1% Triton X-100, 0.1% SDS, 0.5% sodium taurocholate). 3.5 μg of total protein from each extract was prepared in 1x LDS sample buffer containing 2.5% β-mercaptoethanol and loaded onto a 4-12% Bis-Tris SDS-PAGE gel. Gels were then run at a constant voltage of 30 V for 30 min followed by 150 V for 1 h. Proteins were transferred to PVDF membranes in 1x NuPAGE transfer buffer containing 10% methanol at 25V for 1 hour. After transfer, DNAI1 protein was detected by Western blot using anti-DNAI1 antibody and developed with alkaline phosphatase chemiluminescent substrate. Western blot values ​​were normalized using Sypro Ruby total protein stain as a loading control and are expressed as relative expression to unmodified RNA. Each data point is the mean ± standard deviation of three biological (transfection) replicates.

[0196] Figures 14, 15 and 16 show the expression of DNAI1 protein in HEK-293, A549 and MLE-15 cells, respectively. DNAI1 was expressed as a 699 amino acid, 79.3 kDa protein. Pseudouridine (Ψ)-containing transcripts expressed well in all three cell types, at expression levels equal to or higher than the unmodified RNA. Similarly, 1-methylpseudouridine (m 1 Ψ)-containing transcripts produced expression levels equal to or higher than the unmodified RNA in A549 and MLE15 cells (expression in HEK-293 cells was not tested for this transcript). Importantly, the expression levels of each transcript and their relative ranking were similar in each cell line, indicating no cell type-specific effects on DNAI1 translation. Figure 17 is a graph showing the relative expression of DNAI1 protein in HEK-293, A549 and MLE-15 cells. Western blot signal values ​​were normalized using total protein staining and plotted as the mean expression ± standard deviation relative to unmodified DNAI1 mRNA.

[0197] Table 11 summarizes the relative expression of DNAI1 protein in each of the above cell lines. [Table 11]

[0198] [Example 7] Immunogenicity of nucleic acid constructs encoding human DNAI1 in vitro The immunogenicity of the above transcripts was tested by measuring cytokine production in two cell lines, A549 adenocarcinoma human alveolar basal epithelial cells and HepG2 human hepatoma cells. IL-6 production in response to the transcripts was measured in A549 cells, and IP-10 production was measured in HepG2 cells. Each cell line was transfected with a titer of each RNA in triplicate. Briefly, either 20,000 (A549) or 40,000 (HepG2) cells were plated per well and transfected 24 hours later in a 96-well plate. Cells were then transfected with a titer of each transcript: 250ng-7ng per well for unmodified, 50%Ψ and 100%Ψ transcripts and 1000ng-32ng per well for 100%m1Ψ mRNA using MessengerMax reagent at an RNA:MessengerMax ratio of 1:1.5.

[0199] Culture supernatants were harvested 18 hours after transfection. Cell viability was measured immediately after supernatant harvest using the CellTiter-Glo assay kit (Promega), which measures ATP levels as an indicator of metabolically active cells. For IL-6 detection, A549 cell culture supernatants were diluted 1:20 in assay buffer and IL-6 levels were measured using the IL-6 High Sensitivity Human ELISA Kit (Abcam ab46042). IP-10 was detected in undiluted HepG2 cell culture supernatants using the human IP-10 ELISA kit SimpleStep (Abcam ab173194).

[0200] Figures 18 and 19 show the induction of IL-6 in A549 cells treated with DNAI1 transcripts. For the assay shown in Figure 18, cells were exposed to RNA-MessengerMax complexes for 18 hours, and for the assay shown in Figure 19, RNA-MessengerMax complexes were removed 2 hours after transfection. In both cases, cell culture supernatants were harvested at 18 hours for detection of IL-6 by ELISA. Figures 20 and 21 show the cell viability of the assay shown in Figures 18 and 19, measured using the CellTiter-Glo assay. Figure 22 shows the induction of IP-10 in HepG2 cells by DNAI1 transcripts. For this assay, cells were exposed to RNA-MessengerMax complexes for 18 hours. IP-10 expression induced by various amounts of each DNAI1 mRNA was then measured by ELISA. Figure 23 shows the cell viability of the assay shown in Figure 22, measured using the CellTiter-Glo assay.

[0201] [Example 8] Translation of DNAI1 mRNA in HEK293 cells Figure 24 shows peak expression of a nucleic acid encoding axonemal dynein intermediate chain 1 (DNAI1) or a nucleic acid control in HEK293 cells. As shown in Figure 24, in HEK293 cells, translation of the DNAI1 nucleic acid construct in HEK293 cells peaks at 6 hours but is still present at 48 hours.

[0202] [Example 9] Expression of DNAI1 protein in undifferentiated and fully differentiated human airway epithelial cells (HAEC) and mouse tracheal epithelial cells (MTEC) following administration of lipoplex-formulated 100% m1Ψ-containing DNAI1 mRNA.

[0203] Expression of DNAI1 protein in primary human airway epithelial cells and mouse tracheal epithelial cells after treatment with lipoplex-formulated DNAI1-HA mRNA was assessed by Western blot. The 100% m1Ψ-containing transcript used in this experiment was generated from an alternate codon usage template of DNAI1 (SEQ ID NO: 15) containing an HA epitope tag. Primary human epithelial cells were maintained in submerged culture or at the air-liquid interface for undifferentiated cultures and allowed to differentiate into fully differentiated ciliated epithelium for approximately 3 weeks. Then, 12 or 24 μg of lipoplex-formulated DNAI1-HA mRNA was applied to the apical side of fully differentiated cultures or directly to undifferentiated liquid cultures. Cells were treated once a day for one or two consecutive days. Cells were then harvested 24 or 48 hours after the final treatment, and whole-cell extracts were prepared in RIPA buffer (50 mM Tris-HCl pH 8, 150 mM NaCl, 1% Triton X-100, 0.1% SDS, 0.5% sodium taurocholate). Total proteins from each extract were separated on 4-12% Bis-Tris SDS-PAGE gels and transferred to PVDF membranes. DNAI1-HA protein was detected by Western blot using an anti-HA antibody and developed with an enhanced chemiluminescence substrate. As shown in Figure 25, DNAI1-HA protein was expressed at high levels in both undifferentiated and fully differentiated ciliated human and mouse airway epithelial cells.

[0204] [Example 10] Altered nucleotide usage in the coding region enhances mRNA stability for transcript therapy.

[0205] Altered nucleotide usage schemes, which aim to reduce the number of more reactive dinucleotides within and across codons of modified mRNAs, partially alleviate the limitations imposed by the inherent chemical instability of RNA. At the same time, reducing the U content in RNA transcripts reduces their immunogenicity. Traditional codon optimization (CO) can be performed prior to the removal of (+) reactive dinucleotides and (+) U reduction, resulting in an ORF commonly referred to as CO++.

[0206] Figure 26 shows the overall quality improvement in DNAI1 expressing polyribonucleotide of SEQ ID NO: 15 (B) compared to polyribonucleotide of SEQ ID NO: 14 (A). The overall quality improvement is judged by the increase in the % of major RNA peaks in the fragment analyzer trace in polyribonucleotides engineered with an altered codon usage strategy. Furthermore, the CO++ optimized open reading frame, i.e. DNAI1 mRNA featuring altered codon usage, shows an improvement in translation efficiency in transfected A549 cells when compared to the traditionally optimized transcript (CO) (see Figure 27). Here, 1.25x10 per well was used to determine the overall quality improvement. 6 Cells were plated and transfected 18 hours later in 6-well plates. Cells were transfected with approximately 100 ng of each RNA using MessengerMax transfection reagent at a 1:12 RNA:MessengerMax ratio and harvested 6 hours post-transfection. Western blotting with anti-DNAI1 antibody revealed expression of DNAI1 protein as a 699 amino acid, 79.3 kDa protein. Relative translation efficiency is shown as the average of three biological (transfection) replicates.

[0207] A change in reactivity with J2 antibody sensing double-stranded RNA content was observed, as shown in Figure 28. Based on comparison with known concentrations of poly-IC, the dsRNA content of the mRNA encoding DNAI1, characterized by a CO++ ORF, was estimated to be 39 ng on average, while the RNA with the CO ORF contained 68 ng of dsRNA contamination when dotted with 200 ng of in vitro transcribed mRNA.

[0208] [Example 11] Unmodified and 100%m 1 HPLC purification of Ψ-containing DNAI1 mRNA.

[0209] Reverse-phase high performance liquid chromatography (HPLC) of DNAI1 mRNA was used to purify full-length RNA and remove contaminants such as long dsRNA generated during in vitro transcription with T7 RNA polymerase. Fractionation and purification results obtained using a non-porous RNASep C18 semi-prep (100 mm x 21.2 mm, column volume (CV) approximately 2.4 mL) column with a mobile phase containing triethylammonium acetate (TEAA) as an ion-pairing agent and increasing acetonitrile content are shown in Figure 29. As judged by fragment analyzer evaluation of purified fractions, an overall quality improvement and full-length RNA enrichment was observed using the semi-prep RNASep column. This quality improvement was observed for unmodified (A, B) and 100% m 1 This was achieved for both Ψ-containing DNAI1 mRNA species (C, D).

[0210] As shown in Figure 30, a moderate improvement in translation activity was observed with full-length unmodified mRNA transcript enriched fractions in A549 cells (A and B). Here, 1x10 per well 6A549 cells were plated at 100 ng of each RNA and transfected 18 hours later in 6-well plates. Cells were transfected with approximately 100 ng of each RNA using MessengerMax transfection reagent at a 1:12 RNA:MessengerMax ratio and harvested 6 hours post-transfection. Western blotting using rabbit anti-DNAI1 (AbCam ab166912, rabbit monoclonal anti-DNAI1 against recombinant DNAI1 fragment) antibody at 1:2000 revealed expression of DNAI1 protein as a 699 amino acid, 79.3 kDa protein (C). Relative translation efficiency is shown as the mean ± standard deviation of three biological (transfection) replicates.

[0211] Importantly, HPLC easily removes late-eluting dot blot reactive species at the semi-prep scale. Detectable double-stranded RNA content reacting with the J2 antibody was observed exclusively in the late-eluting fraction F7 and the unpurified control transcript, but was undetectable in all other HPLC-purified DNAI1 mRNA fractions F1-F6 (D). The immunogenicity of the unmodified HPLC-purified transcripts was further tested in A549 cells by monitoring the production of IL-6 in response to the transfected mRNA. Each cell line was transfected with a titer of each RNA in triplicate. Briefly, 20,000 cells were plated per well and transfected 18 hours later in 96-well plates. Cells were then transfected with a titer of each transcript at 250ng-7ng per well using MessengerMax reagent at an RNA:MessengerMax ratio of 1:1.5. A reduced IL-6 response was observed for the HPLC purified fraction F3, which yielded the highest relative DNAI1 protein levels (for cells transfected with 125 ng of RNA, unpurified reference DNAI1 mRNA: (727 ± 109 pg / mL) > F3 (73 ± 30 pg / mL)) (E).
