Description

[0001] Sequence Listing

[0002] This application contains a sequence listing submitted in ASCII format via EFS-Web and is incorporated herein by reference in its entirety. The ASCII copy created on September 17, 2018 is Sequence Listing ST25.txt and is 77KB in size. Background of the Invention

[0004] There are an estimated 5,000-10,000 monogenic diseases, defined as genetic conditions caused by mutations in a single gene. These diseases typically present in childhood and result in multiple symptoms and sometimes even premature death. In total, it is estimated that approximately 6% of the population will be affected by these diseases at some point in their lifetime. Diagnosis and treatment of these diseases remain largely inadequate, and care is primarily palliative, focusing on disease management but not addressing the underlying genetic defect. There are many more diseases in which genetic mutations contribute to the pathogenesis of these diseases.

[0005] Gene editing is a gene therapy approach that relies on designing nucleases to recognize and cut specific DNA sequences, and then utilizes innate cellular DNA repair pathways, namely non-homologous end joining (NHEJ) and homology-directed repair (HDR), to introduce targeted modifications in the genome. Four families of nucleases have been used in this context: meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats-associated RNA-guided Cas9 (CRISPR-Cas9) nucleases. These can be designed to precisely introduce double-strand breaks at the target locus of interest. Gene editing opens the possibility of permanently modifying genomic sequences of interest by achieving targeted destruction, insertion, excision, and correction in both in vitro and in vivo settings. While these advances are expected to revolutionize this field, current gene editing methods are limited by the effectiveness of the modification, safety issues associated with nuclease specificity, and delivery of gene editing tools to target cell types.

[0006] As a component of the type II CRISPR system that constitutes the bacterial innate immune system, the Cas9 (CRISPR-associated) protein has caused a paradigm shift in the field of genome editing due to its ease of use. Programming Cas9 to cut a desired sequence is a simple matter of changing the sequence of the Cas9-associated guide RNA to be complementary to the target site. The ease of Cas9 targeted programming contrasts with the more intensive protein engineering required for other agents (zinc finger nucleases (ZFNs), meganucleases, transcription activator-like effector nucleases (TALENs)). Cas9, as well as proteins from the type III CRISPR system, have been used in countless genome editing applications in a variety of organisms and are now entering the field of human therapeutic applications.

[0007] Cystic fibrosis (CF) is an autosomal recessive genetic disease caused by mutations in the CFTR gene, which encodes an epithelial anion channel. The CFTR protein, cystic fibrosis transmembrane transport regulator, is found in a wide range of organs including the pancreas, kidneys, liver, lungs, gastrointestinal tract, and reproductive tract, making CF a multi-organ disease. Mutations in CFTR lead to suboptimal ion transport and fluid retention, resulting in the prominent clinical manifestations of abnormally thickened lung mucus and pancreatic insufficiency. In the lungs, dysfunctional CFTR impedes mucociliary clearance, making the organ susceptible to bacterial infection and inflammation, ultimately leading to airway occlusion, respiratory failure, and premature death. CF remains the most common and fatal genetic disease in the Caucasian population, with an estimated 70,000-100,000 patients worldwide, highlighting the real need to develop better treatments.

[0008] A major challenge in developing therapeutic strategies for CF is the wide diversity of mutation types. The deltaF508 (phenylalanine deletion at codon 508) mutation, with a prevalence of >80% in CF patients, is by far the most common, but more than 1,990 deleterious CFTR mutations have been described. These mutations result in premature stop codons, aberrant splicing, improper protein folding or trafficking to the cell surface, and dysfunctional CFTR with limited channel opening capacity. Pharmacological interventions have targeted several of these processes, and while drug administration has therapeutic effects in certain gating mutation types, more effective treatments are needed for the common deltaF508. However, advances in drugs to treat CF have not addressed mutations caused by aberrant splicing or premature stop codons; in these cases, gene editing may be most beneficial.

[0009] Similarly, in Western populations, approximately 15% of non-small cell lung cancer (NSCLC) patients carry activating mutations in the EGF receptor (EGFR) gene in their tumors.

[0010] Existing gene editing technologies, such as CRISPR-Cas9 (and Cas9 fusions), meganucleases, zinc finger proteins, type IIS restriction endonucleases (FokI and FokI fusions), and TALENS, are limited in their ability to introduce gene deletions of specific lengths or accurately repair target genes in a sufficient number of cells, which are of interest as therapeutic agents for treating many genetic diseases. In addition, for highly programmable RNA-guided nucleases, such as monomeric Cas9, studies have shown that the specificity of predictably binding, cutting, and repairing only its target site is limited, raising concerns about potential harmful changes to cellular genomic DNA that could inadvertently cause secondary diseases in patients. Finally, most nucleases are delivered in viral vectors. Viral vectors have the following potentials: immunity in many populations; immunogenicity after treatment; and genotoxicity. There is currently no non-viral delivery method that can safely deliver nucleases to target cells and allow controlled administration of nucleases in vivo.

[0011] There is still an unmet need to improve the existing gene editing technology to solve the above-mentioned problems so as to make the gene editing technology more efficient and effective. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 Schematic diagram of a lipid-encapsulated double-cutting nuclease (TevCas9) after its preparation [components are not to scale]. The I-TevI ​​domain 10 is connected to the RNA-guided nuclease (Cas9) domain 12 via a linker domain 11. In a preferred embodiment, the formed particles also contain guide RNA 13 and donor DNA 14. The aforementioned nuclease is contained in a lipid particle 15, which has been formed into a sphere using an extrusion process.

[0013] Figure 2 Figure 2 shows lipid-encapsulated TevCas9 being internalized into the cell and nucleus to reach its target DNA. Figure 2 As shown in A, a cell 20 or a plurality of cells 20 are exposed to a novel lipid-encapsulated nuclease particle 21 containing TevCas9 25 via in vivo or ex vivo administration. Figure 2 As shown in B, the lipid-encapsulated nuclease particle 21 is endocytosed into the cell 20. The endosome 22 undergoes a maturation process in the cytosol and is targeted for degradation ( Figure 2 C) Under certain circumstances, TevCas9 25 can escape from the endosome 22 and enter the cytosol ( Figure 2 D). In eukaryotes, the nuclease (TevCas9) 25 is targeted to the nucleus 23 of the cell 20 via one or more nuclear localization sequences ("NLS"). Figure 2As depicted in E, through its nuclear localization sequence, TevCas9 25 can enter the nucleus 23, and once in the nucleus 23, the TevCas9 nuclease 25 binds and cleaves 26 the target genomic DNA 24 sequence.

[0014] Figure 3 is a diagram of the mechanism by which lipid-encapsulated TevCas9 modifies target DNA. The I-TevI ​​domain 27 targets the I-TevI ​​target sequence 29. The linker domain 30 connects the I-TevI ​​domain 27 to the Cas9 domain 28 that targets the Cas9 target sequence 31. The gene mutation 32 is surrounded by or close to the I-TevI ​​target sequence 29 and the Cas9 target sequence 31. Figure 3 As shown in B, TevCas9 25 cleaves the target sequence, leaving a deletion product 34 of predictable size with non-complementary DNA ends 35, 36. Figure 3 C illustrates that in the presence of single-stranded donor DNA with homology arms 37, cell 20 can insert donor DNA 37 sequence near the cleavage site through homology directed repair (HDR) pathway 38. Figure 3 D illustrates that in the presence of donor DNA 39 having DNA ends compatible with the DNA ends cleaved by TevCas9 25, cell 20 can insert donor DNA sequence 39 between cleavage sites by directional ligation using non-homologous end joining (NHEJ) pathway 40. In the absence of donor DNA, cell 20 can join DNA ends by NHEJ pathway 40 ( Figure 3 E).

[0015] FIG. 4A demonstrates in vitro cleavage of a CFTR DNA substrate using TevCas9 targeting the CFTR gene with the guide in SEQ ID 15. Figure 4B Cells transfected with a plasmid DNA version of TevCas9 fused to a cleavable GFP tag were imaged on a Cytation 5 (Biotek Instruments Inc, VT, USA) using phase contrast and GFP imaging 48 hours after treatment. Genomic DNA was extracted from the collected cells and editing at the CFTR gene was detected by PCR amplification and T7 endonuclease I cleavage assay.

[0016] Figure 5 It was demonstrated that TevCas9 targeting the CFTRδF508 mutation using the guide in SEQ ID 21 cleaved a DNA substrate containing the CFTRδF508 mutation in vitro, but did not cleave a substrate containing the wild-type CFTR sequence.

[0017] FIG6A illustrates that the saCas9 D10E mutation slows down the conversion of nicked supercoiled DNA to linear DNA. Figure 6BWe demonstrate that on a linear EMX1 DNA substrate, the saCas9D10E (D10E) ribonucleoprotein complex (RNP) cleaves the target substrate to a level similar to that of saCas9 wild-type (WT). The editing level of SaCas9D10E on computationally predicted off-targets is lower than that of wild-type saCas9 on the same off-targets.

[0018] Figure 7A is a schematic diagram of the spacing of I-TevI ​​sites in EGFR exon 19 deletion and wild-type (WT) EGFR. Figures 7B and 7C demonstrate that TevCas9 containing a nick mutation in Cas9 (H557A) targeting EGFR using a guide RNA in SEQ ID 16 cuts EGFR exon 19 deletion DNA substrate at a rate 4 times faster than wild-type EGFR. Figure 7D is an image of HCC827 cells carrying EGFR exon 19 deletion mutations treated with TevCas9 targeting EGFR being selectively killed compared to NuLi-1 cells carrying wild-type EGFR (WT).

[0099] ZFN Zinc Finger Nuclease

[0100] The inventors have discovered a chimeric nuclease comprising a modified version of the I-TevI ​​domain, a linker peptide, and a modified version of the RNA-guided nuclease Staphylococcus aureus Cas9 ("saCas9") (hereinafter referred to as "TevCas9"), which, when mixed with lipid nanoparticles with or without exogenous donor DNA, replaces a DNA sequence in the presence of exogenous donor DNA or deletes a defined length of DNA in the absence of exogenous donor DNA when delivered to cells. This novel chimeric nuclease has been shown to edit genes in human cells as well as cells of other organisms such as bacteria, yeast, insects, plants or other mammals, both in whole organisms (in vivo) and in isolated cell cultures (ex vivo).

[0101] The novel chimeric nuclease discovered by the inventors has the following advantages in particular compared to existing gene editing technologies and methods.

[0102] a. The nuclease is a modified version of the TevCas9 nuclease that can target two independent target sites as a single protein and cut DNA at one or both of these sites. It can be reprogrammed to many different target DNA sequences by modifying one or more of the I-TevI ​​domain, the linker domain, the Cas9 domain, or the guide RNA (which targets the Cas9 domain to its target sequence);

[0103] b. If the nuclease cuts at two sites, it cuts a precise length of DNA (~30–36 bases, depending on the sites targeted by I-TevI ​​and Cas9);

[0104] c. The Cas9 domain contains a mutation (D10E) that is rationally designed to modify the Cas9 nuclease activity and / or increase the specificity of the Cas9 domain to its target binding site;

[0105] d. In the presence of exogenous donor DNA, the present invention is designed to replace a higher percentage of target DNA sequences in cells than prior art or practice;

[0106] e. The nuclease can be purified as a single continuous protein bound to the guide RNA, thus simplifying manufacturing;

[0107] f. Lipid nanoparticles allow non-viral delivery to target cells with high efficiency and low toxicity, allowing controlled administration of nucleases. Although other lipid-based nuclease delivery technologies exist, none are suitable compositions for in vivo use;

[0108] g. Lipid nanoparticles have also been designed to deliver nucleases via aerosolization (inhalation);

[0109] h. A version of the nuclease targets and cleaves the CFTR gene to correct the CFTRδF508 mutation for the treatment of cystic fibrosis (SEQ ID NO 1); and

[0110] i. Another version of the nuclease was designed to target and cleave clinically relevant EGFR exon 19 deletion mutations (SEQ ID NOs 2–4), which are present in a variety of cancers, including non-small cell lung cancer (NSCLC).

[0111] It is known that GIY-YIG nucleases such as I-TevI ​​are fused to a DNA binding domain via a flexible linker (WO2014 / 121222). Previous versions of double-cut TevCas9 have been described, comprising amino acids 1-92 of the wild-type I-TevI ​​nuclease domain, a linker region containing amino acids 93-169 of the I-TevI ​​linker region, and Streptococcus pyogenes Cas9 ("spCas9") (Wolfs JM et al., (2016), 'Biasing Genome-Editing Events Toward Precise Length Deletions with an RNA-Guided TevCas9 Dual Nuclease, 'Proc Natl Acad Sci USA, 113 (52): 14988-93). The chimeric nuclease of the present invention comprises the following:

[0112] The iI-TevI ​​nuclease domain binds novel target sequences, allowing targeting of clinically relevant gene sequences, such as the CFTR gene;

[0113] ii. Various flexible linker regions designed to confer different DNA binding or nuclease activities to TevCas9;

[0114] iii. saCas9 nuclease domain (US-1988 / 065406B2). Compared to spCas9, the use of saCas9 produces a smaller DNA coding sequence (~3.7 kilobases for Tev-saCas9 vs. ~4.6 kilobases for Tev-spCas9) and a lower molecular weight TevCas9 protein (~144 kilodaltons for Tev-saCas9 vs. ~179 kilodaltons for Tev-spCas9), which is more suitable for a variety of delivery technologies; as found by the inventors of the claimed technology, compared to spCas9, the cleavage by the saCas9 domain between the 3rd and 4th nucleotides is predictable, which is more suitable for defined length deletions.

[0115] iv. a version in which the guide RNA is targeted to a specific CFTR gene sequence near the CFTRδF508 mutation; and

[0116] v. A second version in which the guide RNA is targeted to a specific EGFR gene sequence and is designed to cleave only DNA with appropriately spaced I-TevI ​​sites and Cas9 target sites. Such appropriately spaced sites are present in certain EGFR exon 19 deletion mutations (SEQ ID NOs 2-4) but not in wild-type EGFR (SEQ ID NO 5);

[0117] a. The present invention includes lipid nanoparticles of certain compositions that are selectively sized to an average diameter of about 100 nM. These lipid nanoparticles are capable of delivering nucleases to cells with high efficiency and low toxicity;

[0118] b. Pharmaceutical preparations of lipids, nucleases and exogenous donor DNA;

[0119] c. a pharmaceutical formulation of lipids, nucleases, and exogenous donor DNA suitable for aerosolization (inhalation); and

[0120] d. One version of the invention contains exogenous donor DNA that, when delivered with the TevCas9 nuclease in lipid nanoparticles, is capable of integrating into the region between or around the two sites targeted by the nuclease.

[0121] The novel chimeric nuclease composition of the present application contains different combinations of I-TevI ​​domain, linker domain, Cas9 domain and guide RNA.

[0123] i. an I-TevI ​​domain according to the amino acid sequence of SEQ ID NO: 6;

[0124] ii. a linker domain according to any one of SEQ ID NOs: 7-12;

[0148] synthesis

[0149] Example 1: Method for making TevCas9 nuclease:

[0150] The DNA coding sequences of the I-TevI ​​domain, the linker domain, and the Cas9 domain mentioned above were synthesized into a continuous DNA sequence using techniques known in the art. Gene synthesis was performed by Bio Basic (Markham, Ontario, Canada). In short, short oligonucleotides (~50–60 base pairs) were synthesized, which contained overlapping regions to cover the entire sequence of the I-TevI ​​domain, the linker domain, and the Cas9 domain. These oligonucleotides were mixed together with blocks of approximately 1 kilobase of the sequence to be synthesized, and these ~1 kilobase blocks were synthesized using polymerase chain reaction (PCR). The ~1 kilobase blocks were then mixed and PCR was performed to synthesize the I-TevI ​​domain, the linker domain, and the Cas9 domain. In addition, in order to enhance the expression of TevCas9 in Escherichia coli and simplify restriction endonuclease digestion, the DNA sequence of TevCas9 was optimized before synthesis. First, three base pair DNA codons that are not commonly used by Escherichia coli ("E. coli") were replaced with more frequently occurring codons (e.g., among the six codons encoding the amino acid arginine, the relative abundance of the codon AGG is 0.03, while the relative abundance of the codon CGT is 0.42). A total of 37% of the codons were changed to codons preferred by E. coli. Second, the content of the nucleotides cytosine and guanine was increased from 39.6% to 48.6%. Third, two E. coli ribosome binding sites were removed from the sequence. Fourth, the NdeI restriction endonuclease site was removed from the internal sequence. The continuous DNA was digested with restriction endonucleases NdeI and BamHI (New England Biolabs, Ipswich, Massachusetts, USA), whose target site only appeared once in the DNA sequence, and then inserted into a similarly digested pET-11a expression vector (EMD Millipore, Burlington, Massachusetts, USA) suitable for expressing TevCas9 in Escherichia coli using DNA ligase (New England Biolabs, Ipswich, Massachusetts, USA). The pET-11a vector containing TevCas9 was transformed into an Escherichia coli expression strain T7 Express (New England Biolabs#C2566, Ipswich, Massachusetts, USA), which has been optimized for the expression of proteins including nucleases. Alternatively, the Escherichia coli expression strain BL-21 (DE3) (New England Biolabs#C2527, Ipswich, Massachusetts, USA) was used. Successful transformation was confirmed by the resistance of E. coli to ampicillin or tetracycline, and the coding sequence of TevCas9 was verified by DNA sequencing of the expression vector derived from the transformed E. coli.As measured by spectrophotometry at a wavelength of 600nM, the transformed Escherichia coli grows to an optical density of 0.4 to 0.6 at 37°C, and the expression of the TevCas9 protein from the pET-11a vector in the Escherichia coli expression strain transformed using IPTG induction at 16°C is 10-12 hours. Compared with the uninduced samples, the successful expression of TevCas9 was verified by the presence of a band of about 150kDa on the SDS-polyacrylamide gel stained by Coomassie in the sample of the induced material. Escherichia coli cells were harvested by centrifugation and resuspended in a lysis buffer comprising 10mM imidazole (Sigma, St.Louis, Missouri, USA), 300-500mM sodium chloride (Sigma-Aldrich, St.Louis, Missouri, USA) and 50mM sodium phosphate (binary) (Sigma, St.Louis, Missouri, USA), pH 8.0 [buffer 1]. Alternatively, the sodium phosphate (binary) in buffer 1 is replaced with 10 mM Tris hydrochloride (Sigma, St. Louis, Missouri, USA) at pH 8. Escherichia coli is lysed by homogenization, using a high pressure liquid homogenizer (Avestin, Ottawa, Ontario, Canada) at 600-1000 bar, or using any other suitable lysis method known in the art, such as using an ultrasonic instrument (Branson Ultrasonics, Danbury, Connecticut, USA) sonication, lysozyme treatment, using a French pressure cell (Glen Mills, Clifton, New Jersey, USA) homogenization or using a Dounce homogenizer (Corning, Corning, New York, USA) homogenization. The cracked material is centrifuged at 12,000 rpm for 20-30 minutes at 4 ° C, and the supernatant containing soluble TevCas9 is used for subsequent purification steps. The precipitation contains cell debris, insoluble intracellular material, and any insoluble TevCas9. Successful lysis and solubilization was verified by the presence of an approximately 150 kDa band on a Coomassie-stained SDS-polyacrylamide gel in the supernatant samples compared to the pelleted resuspended samples.

[0151] TevCas9 nuclease was purified as follows:

[0152] 1. The nuclease-containing lysate was applied to a nuclease-binding immobilized metal affinity chromatography (IMAC) column (GE Healthcare Bio-Sciences AB, Uppsala, Sweden).

[0153] 2. Wash the IMAC column with buffer 1.

[0154] 3. TevCas9 that remained bound to the column was eluted with a solution containing: 250 mM imidazole (Sigma, St. Louis, Missouri, USA), 300 mM-500 mM sodium chloride (Sigma-Aldrich, St. Louis, Missouri, USA) and 50 mM sodium phosphate (dibasic) (Sigma, St. Louis, Missouri, USA), pH 7.6-8.0 [buffer 2]. Alternatively, sodium phosphate (dibasic) in buffer 2 was replaced with 10 mM Tris hydrochloride (Sigma, St. Louis, Missouri, USA) at pH 7.6-8.

[0155] 4. The eluate was treated with tobacco etch virus (TEV) protease (New England Biolabs, Ipswich, MA, USA) and incubated with appropriate guide RNA. The guide RNA was synthesized by Integrated DNA Technology (Coralville, IA, USA).

[0156] 5. Re-apply the treated eluate to the IMAC column and collect the flow-through containing TevCas9 nuclease and guide RNA.

[0157] 6. Successful purification of the TevCas9 nuclease was confirmed by the presence of a 150 kilodalton protein band on a Coomassie-stained SDS-polyacrylamide gel. Successful co-purification of TevCas9 with guide RNA was confirmed by treating the eluate sample with proteinase K (New England Biolabs, Ipswich, MA, USA), then splitting the sample into two and further treating one subsample with RNase A (New England Biolabs, Ipswich, MA, USA), while the other was in a control buffer without RNase A. An RNA band of ~100 nucleotides was visible on the urea-polyacrylamide gel in the control sample, but not in the RNase A-treated sample.

[0158] 7. The solution containing TevCas9 nuclease and guide RNA was dialyzed into a solution containing phosphate buffered saline at pH 7.4.

[0159] Example 2: Method for making lipid nanoparticles:

[0160] The lipid nanoparticles of the preferred embodiment comprise one of the following mixtures:

[0161] I. Lipid nanoparticles No. 1 contain DOPE (Avanti Polar Lipids, Alabaster, AL, United States) and MPEG-5000-DMPE (Avanti Polar Lipids, Alabaster, AL, United States) in a molar ratio of 2:0.05;

[0162] II. Lipid nanoparticles No. 2 comprise DPPC (Avanti Polar Lipids, Alabaster, Alabama, USA), cholesterol (SUPELCO, Bellefonte, PA, United States) and DOBA (Sigma, St. Louis, Missouri, USA) in a molar ratio of 7:2:1, respectively; and

[0163] III.3 lipid nanoparticles contain DPPC, cholesterol and MPEG-5000-DMPE (Avanti Polar Lipids, Alabaster, Alabama, USA) in a molar ratio of 4:1:0.125, respectively.

[0164] Lipid nanoparticles were fabricated with an average diameter of approximately 100 nM.

[0165] Select one of No. 1-3 lipid mixtures. For example, DOPE and MPEG-5000-DMPE are mixed together in an organic solvent such as chloroform with an appropriate molar ratio. The organic solvent is then evaporated, and the dried lipid mixture is resuspended in a solution of phosphate buffered saline containing a pH of 7.4 using a vigorous vortex. The resuspended lipid mixture is then extruded through a 100nM polycarbonate membrane (T&T Scientific Corporation, Knoxville, Tennessee, USA) balanced in phosphate buffered saline to produce lipid nanoparticles with an average diameter of about 100nM. The solution is sterilized by filtration through a 0.2 μM sterile filter (VWR Scientific, Radnor, Pennsylvania, USA). The average diameter and size distribution of lipid nanoparticles are determined by dynamic light scattering (DLS) using Zetasizer (Malvern Panalytical Co., Ltd., Malvern, UK) or other suitable techniques known in the art.

[0166] Example 3: Composition of donor DNA

[0167] The donor DNA contains DNA sequences intended to repair the gene defect. It also contains DNA sequences not found in the target genomic DNA; these sequences do not interfere with normal gene function, but are intended to knock out I-TevI ​​and / or Cas9 sites and / or introduce one or more DNA sequences for tracking the successful repair of the target gene. Examples of donor DNA include, but are not limited to, the following:

[0168] I. Linear single-stranded DNA of varying lengths containing homology regions flanking the site targeted / cleaved by TevCas9;

[0169] II. Linear double-stranded DNA of varying lengths containing homology regions flanking the site targeted / cleaved by TevCas9;

[0170] III. double-stranded DNA of the same length, which is cut by the nuclease and further comprises a DNA end complementary to the DNA end cut by TevCas9;

[0171] IV. a circular double-stranded DNA comprising homology regions flanking the site targeted / cleaved by TevCas9; and

[0172] V. A circular double-stranded DNA comprising an I-TevI ​​target site and a Cas9 target site, wherein the product cleaved from the double-stranded DNA comprises an end complementary to the end cleaved by TevCas9.

[0173] Example 4: Methods for assembling lipid-encapsulated TevCas9 and transfecting cells

[0174] For ex vivo cell transfection: To assemble lipid-encapsulated TevCas9, lipid nanoparticles were mixed with TevCas9 at a molar ratio of 2000:1 in Dulbecco's modified Eagle's medium (DMEM) (Sigma, St. Louis, Missouri, USA) and incubated at room temperature for 10 minutes. Cells were transfected with 8.7 x 10E-17 to 3.1 x 10E-17 moles of lipid-encapsulated TevCas9 per cell.

[0175] For in vivo cell transfection: To assemble lipid-encapsulated TevCas9, lipid nanoparticles were mixed with TevCas9 at a molar ratio of 2000:1 in phosphate-buffered saline and incubated for 10 min at room temperature. The molar ratio of lipid-encapsulated TevCas9 per cell for in vivo transfection was determined.

CRL-4013 TM , American Type Culture Collection, Manassas, VA, USA) and mock-treated CuFi-1 cultures ( CRL-4013 TM CFTR functionality was measured using short-circuit current measurements in a UssingCamber (Warner Instruments, Hamden, Connecticut, USA) in the presence of a chloride gradient in a 1:1 ratio (A.T.C., American Type Culture Collection, Manassas, VA, USA). The effect of TevCas9 treatment in control cell lines (e.g., NuLi-1) was also measured.

[0192] To demonstrate disruption of EGFR expression and activity in a model cell line by inducing one or more EGFR exon 19 deletion mutations, cultures of immortalized epithelial cells expressing one or more EGFR exon 19 deletion mutations, such as the HCC827 cell line ( CRL-2868 TM , American Type Culture Collection, Manassas, VA, USA) were treated with a range of concentrations of lipid-encapsulated TevCas9 (Specific Biologics, Toronto, Ontario, Canada) targeting EGFR exon 19 deletion in phosphate-buffered saline, sterile isotonic saline, or water for injection. Appropriate control cell lines were used, such as NuLi-1 ( CRL-4011 TM , American Type Culture Collection, Manassas, VA) or immortalized epithelial cell lines.

[0194] Example 1: Animal model testing planned to demonstrate efficacy and determine dose-limiting toxicity

[0195] In an exemplary method demonstrating correction of CFTRδF508 and / or cystic fibrosis symptoms treated with lipid-encapsulated TevCas9 in an animal model (e.g., mouse, rat, minipig, or ferret), lipid-encapsulated TevCas9 targeting CFTRδF508 in a pharmaceutical formulation of phosphate-buffered saline, sterile isotonic saline, or water for injection is delivered directly to the lungs by intubation or intranasal administration. The procedure time for each treatment is approximately 30-6000 seconds, depending on the animal model used.

[0196] In another method, lipid-encapsulated TevCas9 in a drug formulation targeting CFTRδF508 was nebulized using a commercial nebulizer ( (Trudell Medical, London, Ontario, Canada) or PARI-LC (PARI USA, Midlothian, Virginia, USA)) atomization. After atomization, the average size of the lipid nanoparticles was confirmed to be about 100nM by dynamic light scattering (DLS) using a Zetasizer (Malvern Panalytical Co., Ltd., Malvern, UK) or other suitable techniques known in the art. The composition and concentration of lipid-encapsulated TevCas9 were confirmed using a MicroGram lipid assay kit (ProFoldin, Hudson, Massachusetts, USA) and a band of about 150kDa on a Coomassie-stained SDS-polyacrylamide gel after atomization. For the measurement of gene correction rate, a representative sheep (minipig) animal model homozygous for the CFTRδF508 mutation (Exemplar Genetics, Sioux City, Iowa, USA) was exposed to lipid-encapsulated TevCas9 targeting CFTRδF508 and appropriate controls through the mouth, nose or directly to the lungs. General maintenance of these animals includes breeding and littering; age-appropriate biosecure housing; good nutrition; basic vaccinations and veterinary care; and documentation consistent with animal welfare guidelines. Maintenance of these CFTRδF508-specific animals may include one or more of the following: surgery to treat intestinal obstruction; pancreatic enzyme replacement therapy; vitamins and H2 blockers; and / or proton pump inhibitors to improve gastric acid control. Minipigs were treated with a range of concentrations of lipid-encapsulated TevCas9 that were predicted to be effective for 2 days to 4 weeks for acute toxicity studies based on the model cell line studies described above, and for up to 24 months for chronic toxicity studies.

[0197] Monitor the general health of the animals after treatment to assess any adverse events associated with treatment, such as changes in behavior, body weight, or food consumption; immune response; changes in cardiovascular health; death, etc. Other post-treatment efficacy measures may include:

[0198] I. Forced expiratory volume, such as the forced expiratory volume (or other appropriate method) for each animal after treatment;

[0199] II. Overall survival rate of each animal relative to controls;

[0200] III. Other lung function measurements (e.g., use of a mechanical ventilator that allows for general lung function assessment); and

[0201] IV. Measuring mutations in vivo by tissue sampling and mutation detection methods such as polymerase chain reaction.

[0202] After treatment with lipid-encapsulated TevCas9, animals were sacrificed and lung and tracheal tissues were harvested.

[0203] By T7 endonuclease I assay ( Mutation Detection Kit, New England Biolabs #E3321, Ipswich, MA, USA), restriction endonuclease digestion of PCR-amplified target sites (New England Biolabs, Ipswich, MA, USA), deep gene sequencing using the Illumina MiSeq system and barcoded primers flanking the target sites (Illumina, San Diego, CA, USA), or other suitable methods to measure the proportion of CFTRδF508 corrected cells relative to uncorrected cells.

[0204] In a method demonstrating disruption of one or more EGFR exon 19 deletion mutations and / or symptoms of non-small cell lung cancer (NSCLC) treated with TevCas9 in an animal model, a lipid-encapsulated TevCas9 targeting an EGFR exon 19 deletion mutation in a pharmaceutical formulation of phosphate-buffered saline, sterile isotonic saline, or water for injection is delivered directly to the lungs by mouth, nose, or directly to the lungs. The procedure time for each treatment is approximately 30-6000 seconds, depending on the animal model used.

[0205] In another approach, lipid-encapsulated TevCas9 targeting EGFR exon 19 deletion mutations in a pharmaceutical formulation was nebulized using a commercial nebulizer ( (Trudell Medical, London, Ontario, Canada) or PARI-LC (PARI USA, Midlothian, Virginia, USA)) atomization. After atomization, the average size of the lipid nanoparticles was confirmed to be about 100nM by dynamic light scattering (DLS) using a Zetasizer (Malvern Panalytical Co., Ltd., Malvern, UK) or other suitable techniques known in the art. The composition and concentration of lipid-encapsulated TevCas9 nanoparticles were confirmed using a MicroGram lipid assay kit (ProFoldin, Hudson, Massachusetts, USA) and a band of about 150kDa on a Coomassie-stained SDS-polyacrylamide gel after atomization. In order to measure the gene disruption rate, a representative mouse (mouse) animal model homozygous for one or more EGFR exon 19 deletion mutations was exposed to lipid-encapsulated TevCas9 targeting EGFR exon 19 deletions through the nose, mouth or directly to the lungs. Mice were treated with a range of concentrations of TevCas9, which was predicted to be effective for acute toxicity studies for 2 days to 4 weeks based on model cell line studies, and effective for chronic toxicity studies for up to 24 months.

[0206] Monitor the general health of the animals after treatment to assess any adverse events associated with treatment, such as changes in behavior, weight, or food consumption; immune response; changes in cardiovascular health; death, etc. Other post-treatment efficacy measures may include:

[0207] I. Quantification of EGFR activated protein by positron emission tomography (PET) using EGFR mutation tracers;

[0208] II. Overall survival rate of each animal relative to controls; and

[0209] III. Measurement of tumor formation / reduction in each animal over time.

[0210] Through tissue sampling and mutation detection methods such as The EGFR mutation test version 2 (Roche Diagnostics, Risch-Rotkreuz, Switzerland) measured in vivo mutations. After treatment with aerosolized lipid-encapsulated TevCas9, animals were sacrificed and lung and tracheal tissues were harvested.

[0211] By T7 endonuclease I assay ( Mutation Detection Kit, New England Biolabs # E3321, Ipswich, Massachusetts, USA), restriction endonuclease digestion of PCR-amplified target sites (New England Biolabs, Ipswich, Massachusetts, USA), deep gene sequencing using the Illumina MiSeq system and barcode primers flanking the target sites (Illumina, San Diego, California, USA) or other suitable methods to measure the ratio of cells destroyed by EGFR exon 19 deletion mutations relative to undestroyed cells. EGFR protein expression and activity in harvested tissue cells were measured using enzyme-linked immunosorbent assay (ELISA) (Sigma, St. Louis, Missouri, USA), which detects phosphorylated (i.e., activated), unphosphorylated and total EGFR protein. The dose-limiting toxicity that can be determined for the first human clinical study is based on the predicted effective dose from the above-mentioned animal model studies. A series of concentrations (e.g., milligrams per kilogram of body weight) of lipid-encapsulated TevCas9 are atomized and delivered to suitable animal models for toxicology studies, such as crab-eating monkeys or other non-human primates. The animals' general health is monitored for any adverse events related to treatment, such as changes in behavior, body weight, or food consumption; immune response; changes in cardiovascular health; death, etc. Other measures of efficacy that may be measured in the study include those listed above.

[0212] Treatment Effects

[0213] The novel chimeric nucleases of the present invention have been intentionally designed to modify the DNA of lung epithelial cells to treat monogenic diseases, although they can function in vivo or ex vivo in other cell types or cells of other organisms such as bacteria, yeast, insects, plants or other mammals to treat monogenic or polygenic and infectious diseases.

[0214] Example 1: Method for targeted insertion or replacement of DNA sequences in all or part of the human cell genome

[0215] Figure 2 The mechanism of action of the cellular uptake of the novel chimeric nuclease of the present invention is described. Figure 2 As shown in A, a cell 20 or a plurality of cells 20 are exposed to a novel lipid-encapsulated nuclease particle 21 containing TevCas9 25 by in vivo or ex vivo administration. Figure 2 As shown in Figure B, the lipid-encapsulated nuclease particle 21 is internalized into the cell 20, and the endosome 22 undergoes a maturation process in the cytosol and is targeted for degradation ( Figure 2 C) Under certain circumstances, TevCas9 25 can escape from the endosome 22 and enter the cytosol ( Figure 2D). In eukaryotes, the nuclease (TevCas9) 25 is targeted to the nucleus 23 of the cell 20 via one or more nuclear localization sequences ("NLS"). Figure 2 As depicted in E, through its nuclear localization sequence, TevCas9 25 can enter the nucleus 23, and once in the nucleus 23, the TevCas9 nuclease 25 binds and cleaves 26 the target genomic DNA 24 sequence.

[0216] Figure 3 The mechanism by which the TevCas9 nuclease cleaves DNA is illustrated. Figure 3 A shows key features of TevCas9 shown bound to its target genomic DNA sequence 24 prior to the cleavage reaction. The I-TevI ​​domain 27 targets the I-TevI ​​target sequence 29. The linker domain 30 connects the I-TevI ​​domain 27 to the Cas9 domain 28 targeting the Cas9 target sequence 31. The genetic mutation 32 is surrounded by or close to the I-TevI ​​target sequence 29 and the Cas9 target sequence 31. Figure 3 As shown in B, TevCas9 25 cleaves the target sequence, leaving a deletion product 34 of predictable size with non-complementary DNA ends 35, 36. Figure 3 C illustrates that in the presence of single-stranded donor DNA with homology arms 37, cell 20 can insert donor DNA 37 sequence near the cleavage site through homology directed repair (HDR) pathway 38. Figure 3 D illustrates that in the presence of donor DNA 39 having DNA ends compatible with the DNA ends cleaved by TevCas9 25, cell 20 can insert donor DNA sequence 39 between cleavage sites by directional ligation using non-homologous end joining (NHEJ) pathway 40. In the absence of donor DNA, cell 20 can join DNA ends by NHEJ pathway 40 ( Figure 3 E).

[0217] Example 2: Treatment of Cystic Fibrosis

[0218] For the treatment of cystic fibrosis, the exogenous donor DNA comprises a DNA sequence that repairs the CFTRδF508 mutation, and involves a method of using the exogenous donor DNA as a template to target and delete a DNA sequence of a defined length in human somatic cells to stimulate homology-directed repair ( Figure 3 C).

[0219] Example 3: Treatment of non-small cell lung cancer

[0220] For the application of treating non-small cell lung cancer, a Cas9 domain version that cuts only one strand of DNA (D10A or H557A mutation) or a nuclease-deficient version (D10A+H557A mutation) is used, and the sequence targeted is the EGFR exon 19 deletion mutation (SEQ ID NO: 2-4). However, in the present application, the nuclease does not contain exogenous donor DNA. In the absence of exogenous donor DNA, the cell can remove the DNA sequence between the two sites targeted by the nuclease by non-homologous end joining ( Figure 3 E).

[0221] Alternatively, the inhalation route is a rapid and effective way to deliver drugs locally to the lungs and for systemic administration of certain agents. Inhaled drug therapy is widely used to treat respiratory disorders such as asthma and chronic obstructive pulmonary disease (COPD). Research is ongoing to develop an inhalation system for the treatment of cystic fibrosis.

[0222] The following examples are not intended to limit the scope of the present disclosure, but are provided to illustrate how to make and use the compounds disclosed herein.Many other embodiments of the present disclosure will be apparent to those skilled in the art.

[0223] A nebulizer is a device that delivers medication to the lungs in the form of an aerosolized vapor. Nebulizers are commonly used to treat respiratory diseases such as asthma and COPD, for example, the nebulization of corticosteroids, although nebulization has also been used to treat and prevent lung infections such as (Insmed Incorporated, Bridgewater, New Jersey, USA).

[0224] Nebulizers may require some procedures to prepare the liquid for nebulization. The drug is usually placed in a cup in the nebulizer chamber in liquid form. After loading, the device is turned on and compressed air is generated to convert the liquid into vapor in the nebulizer chamber. The patient puts the mouthpiece of the nebulizer chamber into his mouth and takes a deep breath, holding his breath for 5-10 seconds to ensure that the drug reaches the lower part of the lungs. There are many such devices. Many modern nebulizers are breath-activated and rely on the force of the patient's inhalation to bring the nebulized liquid out of the device, thereby ensuring that the drug is delivered only to the patient and not the surrounding environment. This also ensures the consistency of delivering a full dose of drug to the patient.

[0225] The use of nebulizers is well known and nebulizers are commercially available from a number of sources, such as (Trudell Medical, London, Ontario, Canada) or PARI-LC (PARI USA, Midlothian, Virginia, USA). In an example of the present invention, a nebulizer is used to deliver the lipid-encapsulated novel chimeric nuclease of the present application comprising a modified I-TevI ​​nuclease domain, a linker, and a modified RNA-guided nuclease Staphylococcus aureus Cas9 to lung epithelial tissue. A sterile liquid version of the therapeutic agent of interest is loaded into the nebulizer chamber and then atomized and inhaled into the lungs by the patient through deep breathing.

[0226] Some advantages of using a nebulizer over oral or intravenous administration are that: less medication may be required than with oral or intravenous administration; onset of action may be faster via inhalation than with the oral route; adverse effects may be less severe because the medication is delivered locally to the lung tissue where the disease itself occurs; and inhaled medication therapy is painless and relatively comfortable for the patient, which encourages compliance.

[0227] No non-invasive route of administration can provide the speed of action that inhaled drugs can provide. One of the advantages of inhaled drugs is that they are absorbed faster than subcutaneously injected molecules and provide a more immediate physiological response. Small or large molecules, especially hydrophobic molecules, can be absorbed within seconds after inhalation and can therefore be used to treat a variety of symptoms that occur suddenly or require long-term administration. Pain, panic, anxiety, nausea, cardiovascular crisis, bronchoconstriction, sleep induction, spasms, Parkinson's lock-up and hot flashes are some of the rapid onset conditions that inhaled drugs can address.

[0228] Most protein-based drug products have a certain water solubility and can be quickly and effectively absorbed from the lungs. Those that are more hydrophobic are even absorbed faster within seconds to minutes. Those that are more hydrophilic are absorbed within minutes to tens of minutes. In an example of the present invention, a vial is aseptically filled with a therapeutic dose of hydrophobic lipid nanoparticles, and another vial is aseptically filled with a therapeutic dose of chimeric nuclease, the chimeric nuclease comprising a modified I-TevI ​​nuclease domain, a linker, and a modified RNA-guided nuclease Staphylococcus aureus Cas9, which is water-soluble and hydrophilic for delivery to the lungs at a therapeutic dose. The dosage range of lipid nanoparticles and chimeric nucleases can be 1 to 1000 mg, preferably about 5 to 200 mg. The claimed lipid-encapsulated chimeric nuclease comprising a modified I-TevI ​​nuclease domain, a linker, and a modified RNA-guided nuclease Staphylococcus aureus Cas9 can be absorbed by lung cells within a few hours, and complete cutting on an in vitro DNA substrate has been observed within 2 hours. Other aerosol therapy has been delivered every day. Therefore, the aerosol application of lipid-encapsulated chimeric nuclease can be used once a day or less frequently, depending on its efficacy based on each patient. Chimeric nuclease is produced by BioVectra (Charlottetown, PE, Canada), and vials are aseptically filled by Dalton Pharma Services (Mississauga, Ontario, Canada). Lipid nanoparticles are manufactured and aseptically filled vials by TransferraNanosciences (Burnaby, BC, Canada).

[0229] The dosage of any disclosed composition will vary according to the patient's symptoms, age and weight, the nature and severity of the illness to be treated or prevented, the route of administration and the form of the composition. Any of the present preparations can be administered in a single dose or divided doses. The dosage of the composition can be easily determined by techniques known to those skilled in the art or as taught herein.

[0230] In certain embodiments, the dosage of the present compound is generally in the range of about 1 to 1000 mg, particularly in the range of about 5 to 200 mg, depending on the patient's body weight.

[0231] For any particular composition of the present disclosure, it may be necessary to determine an effective dose or amount and any possible effects on the time of administration of the formulation. This can be accomplished by routine experimentation as described herein, using one or more groups of animals (preferably at least 5 animals per group), or if appropriate, in human trials. The effectiveness of any of the present compositions and methods of treatment or prevention can be assessed by administering the composition and evaluating the effect of the administration by measuring one or more applicable indices and comparing the post-treatment values ​​of these indices with the pre-treatment values ​​of the same indices.

[0232] The precise time and amount of administration of any particular present composition that will produce the most effective treatment in a given patient will depend on the activity, pharmacokinetics and bioavailability of the present composition, the patient's physiological condition (including age, sex, disease type and stage, general physical condition, response to a given dose and drug type), route of administration, etc. The guide proposed herein can be used to optimize treatment, such as determining the best time and amount of administration, which will only require routine experiments consisting of monitoring the subject and adjusting the dosage and / or time. When the subject is receiving treatment, the health of the patient can be monitored by measuring one or more related indicators at a predetermined time during treatment. Treatments including compositions, amounts, time of administration, and preparations can be optimized according to the results of this monitoring. By measuring the same parameters, the patient can be reassessed regularly to determine the degree of improvement. The amount of the present composition used and possibly the time of administration can be adjusted based on these reassessments.

[0233] Treatment may be initiated with a smaller dose which is less than the optimum dose of the compound. Thereafter, the dose may be increased by small increments until the optimum therapeutic effect is achieved.

[0234] The use of the present combination can reduce the required dosage of any single agent contained in the combination, because the onset and duration of action of the different agents can be complementary. The therapeutic efficacy of the present combination can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, such as for determining LD 50 and ED 50 .

[0235] The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of any present composition is preferably in the range of ED 50 The dosage may vary within this range, depending on the dosage form employed and the route of administration utilized. For the compositions of the present disclosure, the therapeutically effective dose can be initially estimated from cell culture assays.
