Abstract
Description
LIPID NANOPARTICLE FORMULATIONS AND METHODS OF USE THEREOF1. FIELD
[0001] The present disclosure generally relates to lipid nanoparticle (LNP) comprising a payload molecules (i.e., nucleic acid molecules and / or therapeutic agents) and methods of use thereof for in vivo delivery of the payload molecules to a target cell or tissue.2. DESCRIPTION OF THE RELATED ART
[0002] There are many challenges associated with manipulation in vivo , e.g., modification of specific cells, represents a continuing medical challenge. Modifying a cell in vivo , e.g., for delivery of nucleic acid molecules such as mRNA, or delivery of other payloads, is challenging for many reasons, including the difficulty in specifically targeting cells of interest in vivo to modify them.
[0003] Hematopoietic stem cells (HSCs) are vital adult stem cells that can self-renew and rebuild the entire human hematopoietic system. Ex vivo gene therapy strategies involve the collection of patient HSCs, genetically modifying and transplanting these HSCs, but the process can be harmful due to bone marrow (BM) transplantation and conditioning. Gene editing of hematopoietic stem cells (HSCs) with lipid nanoparticles (LNPs) has not been reported.
[0004] Thus, there exists a need to develop methods and compositions that can target desired cells and deliver a payload for modifying the cells in vivo. In particular, modification of stem or progenitor cells to thereby modify many cell types in a particular lineage in vivo would be of tremendous benefit.3. SUMMARY

[0274] Terminology
[0275] Unless described otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. For purposes of interpreting this specification, the following description of terms will apply and whenever appropriate, terms used in the singular will also include the plural and vice versa. All patents, applications, published applications, and other publications are incorporated by reference in their entirety. In the event that any description of terms set forth conflicts with any document incorporated herein by reference, the description of term set forth below shall control.
[0276] As used herein and unless otherwise specified, the term “lipid” refers to a group of organic compounds that include, but are not limited to, esters of fatty acids and are generally characterized by being poorly soluble in water, but soluble in many nonpolar organic solvents. While lipids generally have poor solubility in water, there are certain categories of lipids (e.g., lipids modified by polar groups, e.g., DMG-PEG2000) that have limited aqueous solubility and can dissolve in water under certain conditions. Known types of lipids include biological molecules such as fatty acids, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids. Lipids can be divided into at least three classes: (1) “simple lipids, ” which include fats and oils as well as waxes; (2) “compound lipids, ” which include phospholipids and glycolipids (e.g., DMPE-PEG2000) ; and (3) “derived lipids” such as steroids. Further, as used herein, lipids also encompass lipidoid compounds. The term “lipidoid compound, ” also simply “lipidoid” , refers to a lipid-like compound (e.g. an amphiphilic compound with lipid-like physical properties) .
[0277] As used herein and unless otherwise specified, the term “delivering” means providing an entity to a destination. For example, delivering a therapeutic and / or prophylactic to a subject may involve administering a LNP including the therapeutic and / or prophylactic to the subject (e.g, by an intravenous, intramuscular, intradermal, pulmonary or subcutaneous route) . Administration of a LNP to a mammal or mammalian cell may involve contacting one or more cells with the lipid nanoparticle. The term “lipid nanoparticle” or “LNP” refers to a particle having at least one dimension on the order of nanometers (nm) (e.g., 1 to 1,000 nm) , which contains one or more types of lipid molecules. The LNP provided herein can further contain at least one non-lipid payload molecule (e.g., one or more nucleic acid molecules) . In some embodiments, the LNP comprises a non-lipid payload molecule either partially or completely encapsulated inside a lipid shell. Particularly, in some embodiments, wherein the payload is a negatively charged molecule (e.g., mRNA encoding a viral protein) , and the lipid components of the LNP comprise at least one cationic lipid. Without being bound by the theory, it is contemplated that the cationic lipids can interact with the negatively charged payload molecules and facilitates incorporation and / or encapsulation of the payload into the LNP during LNP formation. Other lipids that can form part of a LNP as provided herein include but are not limited to neutral lipids and charged lipids, such as steroi. ds, polymer conjugated lipids, and various zwitterionic lipids.
[0278] As used herein, the term "encapsulate" means to enclose, surround, or encase. In some embodiments, a compound, polynucleotide (e.g, an mRNA) , or other composition may be fully encapsulated, partially encapsulated, or substantially encapsulated.
[0279] For example, in some embodiments, an mRNA of the disclosure may be encapsulated in a lipid nanoparticle, e.g, a liposome.
[0280] As used herein, by "liposome" is meant a structure including a lipid-containing membrane enclosing an aqueous interior. Liposomes may have one or more lipid membranes. Liposomes include single-layered liposomes (also known in the art as unilamellar liposomes) and multi-layered liposomes (also known in the art as multilamellar liposomes) .
[0281] As used herein, "encapsulation efficiency" refers to the amount of a therapeutic and / or prophylactic that becomes part of a LNP, relative to the initial total amount of therapeutic and / or prophylactic used in the preparation of a LNP. For example, if 97 mg of therapeutic and / or prophylactic are encapsulated in a LNP out of a total 100 mg of therapeutic and / or prophylactic initially provided to the composition, the encapsulation efficiency may be given as 97%. As used herein, "encapsulation" may refer to complete, substantial, or partial enclosure, confinement, surrounding, or encasement.
[0282] The term “cationic lipid” refers to a lipid that is either positively charged at any pH value or hydrogen ion activity of its environment, or capable of being positively charged in response to the pH value or hydrogen ion activity of its environment (e.g., the environment of its intended use) . Thus, the term “cationic” encompasses both “permanently cationic” and “cationisable” . In certain embodiments, the positive charge in a cationic lipid results from the presence of a quaternary nitrogen atom. In certain embodiments, the cationic lipid comprises a zwitterionic lipid that assumes a positive charge in the environment of its intended use (e.g., at physiological pH) . In certain embodiments, the cationic lipid is one or more lipids of Formula (I) , (Ⅱ) , (Ⅲ) , (Ⅳ) , (Ⅴ) (and sub-formulas thereof) as described herein.
[0283] The term “polymer conjugated lipid” refers to a molecule comprising both a lipid portion and a polymer portion. An example of a polymer conjugated lipid is a pegylated lipid (PEG-lipid) , in which the polymer portion comprises a polyethylene glycol.

In certain embodiments, the monocistronic mRNA encodes a peptide or protein comprising at least one epitope of a selected antigen (e.g., a pathogenic antigen or a tumor associated antigen) . In other embodiments, the mRNA is a multicistronic mRNA that comprises two or more ORFs. In certain embodiments, the multiecistronic mRNA encodes two or more peptides or proteins that can be the same or different from each other. In certain embodiments, each peptide or protein encoded by a multicistronic mRNA comprises at least one epitope of a selected antigen.

As used herein, base pairing encompasses not only the canonical Watson-Crick adenine-thymine, adenine-uracil, or guanine-cytosine base pairs, but also base pairs formed between canonical nucleotides and functional nucleotide analogs or between a pair of functional nucleotide analogs, wherein the arrangement of hydrogen bond donors and hydrogen bond acceptors permits hydrogen bonding between a modified nucleobase and a canonical nucleobase or between two complementary modified nucleobase structures. For example, a functional analog of guanosine (G) retains the ability to base-pair with cytosine (C) or a functional analog of cytosine. One example of such non-canonical base pairing is the base pairing between the modified nucleotide inosine and adenine, cytosine, or uracil. As described herein, a functional nucleotide analog can be either naturally occurring or non-naturally occurring.
[0326] Accordingly, a nucleic acid molecule containing a functional nucleotide analog can have at least one modified nucleobase, sugar group and / or internucleoside linkage. Exemplary chemical modifications to the nucleobases, sugar groups, or internucleoside linkages of a nucleic acid molecule are provided herein.
[0327] As used herein, the term "RNA element" refers to a portion, fragment, or segment of an RNA molecule that provides a biological function and / or has biological activity (e.g., translational regulatory activity) . Modification of a polynucleotide by the incorporation of one or more RNA elements, such as those described herein, provides one or more desirable functional properties to the modified polynucleotide. RNA elements, as described herein, can be naturally-occurring, non-naturally occurring, synthetic, engineered, or any combination thereof. For example, naturally-occurring RNA elements that provide a regulatory activity include elements found throughout the transcriptomes of viruses, prokaryotic and eukaryotic organisms (e.g., humans) . RNA elements in particular eukaryotic mRNAs and translated viral RNAs have been shown to be involved in mediating many functions in cells. Exemplary natural RNA elements include, but are not limited to, translation initiation elements (e.g, internal ribosome entry site (IRES) , see Kieft et al., (2001) RNA 7 (2) : 194-206) , translation enhancer elements (e.g, the APP mRNA translation enhancer element, see Rogers et al, .

A TEE typically locates in the UTR region of a nucleic acid molecule (e.g., mRNA) and enhance the translational level of a coding sequence located either upstream or downstream. For example, a TEE in a 5’-UTR of a nucleic acid molecule can locate between the promoter and the starting codon of the nucleic acid molecule. Various TEE sequences are known in the art (Wellensiek et al. Genome-wide profiling of human cap-independent translation-enhancing elements, Nature Methods, 2013 Aug; 10 (8) : 747-750; Chappell et al. PNAS June 29, 2004 101 (26) 9590-9594) . Some TEEs are known to be conserved across multiple species (Pánek et al. Nucleic Acids Research, Volume 41, Issue 16, 1 September 2013, Pages 7625-7634) .
[0329] As used herein, the term “stem-loop sequence” refers to a single-stranded polynucleotide sequence having at least two regions that are complementary or substantially complementary to each other when read in opposite directions, and thus capable of base-pairing with each other to form at least one double helix and an unpaired loop. The resulting structure is known as a stem-loop structure, a hairpin, or a hairpin loop, which is a secondary structure found in many RNA molecules.
[0330] The term “peptide” as used herein refers to a polymer containing between two and fifty (2-50) amino acid residues linked by one or more covalent peptide bond (s) . The terms apply to naturally occurring amino acid polymers as well as amino acid polymers in which one or more amino acid residues is a non-naturally occurring amino acid (e.g., an amino acid analog or non-natural amino acid) .
[0331] The terms “polypeptide” and “protein” are used interchangeably herein to refer to a polymer of greater than fifty (50) amino acid residues linked by covalent peptide bonds. That is, a description directed to a polypeptide applies equally to a description of a protein, and vice versa. The terms apply to naturally occurring amino acid polymers as well as amino acid polymers in which one or more amino acid residues is a non-naturally occurring amino acid (e.g., an amino acid analog) . As used herein, the terms encompass amino acid chains of any length, including full length proteins (e.g., antigens) .
[0332] The term “antigen” refers to a substance that can be recognized by the immune system of a subject (including by the adaptive immune system) , and is capable of triggering an immune response after the subject is contacted with the antigen (including an antigen-specific immune response) . In certain embodiments, the antigen is a protein associated with a diseased cell, such as a cell infected by a pathogen or a neoplastic cell (e.g., tumor associated antigen (TAA) ) .
[0333] In the context of a peptide or polypeptide, the term “fragment” as used herein refers to a peptide or polypeptide that comprises less than the full length amino acid sequence. Such a fragment may arise, for example, from a truncation at the amino terminus, a truncation at the carboxy terminus, and / or an internal deletion of a residue (s) from the amino acid sequence. Fragments may, for example, result from alternative RNA splicing or from in vivo protease activity. In certain embodiments, fragments refers to polypeptides comprising an amino acid sequence of at least 5 contiguous amino acid residues, at least 10 contiguous amino acid residues, at least 15 contiguous amino acid residues, at least 20 contiguous amino acid residues, at least 25 contiguous amino acid residues, at least 30 contiguous amino acid residues, at least 40 contiguous amino acid residues, at least 50 contiguous amino acid residues, at least 60 contiguous amino residues, at least 70 contiguous amino acid residues, at least 80 contiguous amino acid residues, at least 90 contiguous amino acid residues, at least contiguous 100 amino acid residues, at least 125 contiguous amino acid residues, at least 150 contiguous amino acid residues, at least 175 contiguous amino acid residues, at least 200 contiguous amino acid residues, at least 250, at least 300, at least 350, at least 400, at least 450, at least 500, at least 550, at least 600, at least 650, at least 700, at least 750, at least 800, at least 850, at least 900, or at least 950 contiguous amino acid residues of the amino acid sequence of a polypeptide. In a specific embodiment, a fragment of a polypeptide retains at least 1, at least 2, at least 3, or more functions of the polypeptide.
[0334] An “epitope” is the site on the surface of an antigen molecule to which a single antibody molecule binds, such as a localized region on the surface of an antigen that is capable of being bound to one or more antigen binding regions of an antibody, and that has antigenic or immunogenic activity in an animal, such as a mammal (e.g., a human) , that is capable of eliciting an immune response. An epitope having immunogenic activity is a portion of a polypeptide that elicits an antibody response in an animal. An epitope having antigenic activity is a portion of a polypeptide to which an antibody binds as determined by any method well known in the art, including, for example, by an immunoassay. Antigenic epitopes need not necessarily be immunogenic. Epitopes often consist of chemically active surface groupings of molecules such as amino acids or sugar side chains and have specific three dimensional structural characteristics as well as specific charge characteristics. Antibody epitopes may be linear epitopes or conformational epitopes. Linear epitopes are formed by a continuous sequence of amino acids in a protein. Conformational epitopes are formed of amino acids that are discontinuous in the protein sequence, but which are brought together upon folding of the protein into its three-dimensional structure. Induced epitopes are formed when the three dimensional structure of the protein is in an altered conformation, such as following activation or binding of another protein or ligand. In certain embodiments, an epitope is a three-dimensional surface feature of a polypeptide. In other embodiments, an epitope is linear feature of a polypeptide. Generally an antigen has several or many different epitopes and may react with many different antibodies.
[0335] The term “genetic vaccine” as used herein refers to a therapeutic or prophylactic composition comprising at least one nucleic acid molecule encoding an antigen associated with a target disease (e.g., an infectious disease or a neoplastic disease) . Administration of the vaccine to a subject ( “vaccination” ) allows for the production of the encoded peptide or protein, thereby eliciting an immune response against the target disease in the subject. In certain embodiments, the immune response comprises adaptive immune response, such as the production of antibodies against the encoded antigen, and / or activation and proliferations of immune cells capable of specifically eliminating diseased cells expressing the antigen. In certain embodiments, the immune response further comprises innate immune response. According to the present disclosure, a vaccine can be administered to a subject either before or after the onset of clinical symptoms of the target disease. In some embodiments, vaccination of a healthy or asymptomatic subject renders the vaccinated subject immune or less susceptible to the development of the target disease. In some embodiments, vaccination of a subject showing symptoms of the disease improves the condition of, or treats, the disease in the vaccinated subject.
[0336] The terms “innate immune response” and “innate immunity” are recognized in the art, and refer to non-specific defense mechanism a body’s immune system initiates upon recognition of pathogen-associated molecular patterns, which involves different forms of cellular activities, including cytokine production and cell death through various pathways. As used herein, innate immune responses include, without limitation, increased production of inflammation cytokines (e.g., type I interferon or IL-10 production) , activation of the NFκB pathway, increased proliferation, maturation, differentiation and / or survival of immune cells, and in some cases, induction of cell apoptosis. Activation of the innate immunity can be detected using methods known in the art, such as measuring the (NF) -κB activation.
[0337] The terms “adaptive immune response” and “adaptive immunity” are recognized in the art, and refer to antigen-specific defense mechanism a body’s immune system initiates upon recognition of a specific antigen, which include both humoral response and cell- mediated responses. As used herein, adaptive immune responses include cellular responses that is triggered and / or augmented by a vaccine composition, such as a genetic composition described herein. In some embodiments, the vaccine composition comprises an antigen that is the target of the antigen-specific adaptive immune response. In other embodiments, the vaccine composition, upon administration, allows the production in an immunized subject of an antigen that is the target of the antigen-specific adaptive immune response. Activation of an adaptive immune response can be detected using methods known in the art, such as measuring the antigen-specific antibody production, or the level of antigen-specific cell-mediated cytotoxicity.
[0338] The term “antibody” is intended to include a polypeptide product of B cells within the immunoglobulin class of polypeptides that is able to bind to a specific molecular antigen and is composed of two identical pairs of polypeptide chains, wherein each pair has one heavy chain (about 50-70 kDa) and one light chain (about 25 kDa) , each amino-terminal portion of each chain includes a variable region of about 100 to about 130 or more amino acids, and each carboxy-terminal portion of each chain includes a constant region. See, e.g., Antibody Engineering (Borrebaeck ed., 2d ed. 1995) ; and Kuby, Immunology (3d ed. 1997) . In specific embodiments, the specific molecular antigen can be bound by an antibody provided herein, including a polypeptide, a fragment or an epitope thereof. Antibodies also include, but are not limited to, synthetic antibodies, recombinantly produced antibodies, camelized antibodies, intrabodies, anti-idiotypic (anti-Id) antibodies, and functional fragments of any of the above, which refers to a portion of an antibody heavy or light chain polypeptide that retains some or all of the binding activity of the antibody from which the fragment was derived. Non-limiting examples of functional fragments include single-chain Fvs (scFv) (e.g., including monospecific, bispecific, etc. ) , Fab fragments, F (ab’) fragments, F (ab) 2 fragments, F (ab’) 2 fragments, disulfide-linked Fvs (dsFv) , Fd fragments, Fv fragments, diabody, triabody, tetrabody, and minibody. In particular, antibodies provided herein include immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, for example, antigen-binding domains or molecules that contain an antigen-binding site (e.g., one or more CDRs of an antibody) . Such antibody fragments can be found in, for example, Harlow and Lane, Antibodies: A Laboratory Manual (1989) ; Mol. Biology and Biotechnology: A Comprehensive Desk Reference (Myers ed., 1995) ; Huston et al., 1993, Cell Biophysics 22: 189-224; Plückthun and Skerra, 1989, Meth. Enzymol. 178: 497-515; and Day, Advanced Immunochemistry (2d ed. 1990) . The antibodies provided herein can be of any class (e.g., IgG, IgE, IgM, IgD, and IgA) or any subclass (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2) of immunoglobulin molecule.
[0339] The term “administer” or “administration” refers to the act of injecting or otherwise physically delivering a substance as it exists outside the body (e.g., a lipid nanoparticle composition as described herein) into a patient, such as by mucosal, intradermal, intravenous, intramuscular delivery, and / or any other method of physical delivery described herein or known in the art. When a disease, disorder, condition, or a symptom thereof, is being treated, administration of the substance typically occurs after the onset of the disease, disorder, condition, or symptoms thereof. When a disease, disorder, condition, or symptoms thereof, are being prevented, administration of the substance typically occurs before the onset of the disease, disorder, condition, or symptoms thereof.
[0340] The term “Administering" refers to a method of delivering a composition to a subject or patient. A method of administration may be selected to target delivery (e.g., to specifically deliver) to a specific region or system of a body. For example, an administration may be parenteral (e.g, subcutaneous, intracutaneous, intravenous, intraperitoneal, intramuscular, intraarticular, intraarterial, intrasynovial, intrastemal, intrathecal, intralesional, or intracranial injection, as well as any suitable infusion technique) , oral, trans-or intra-dermal, interdermal, rectal, intravaginal, topical (e.g, by powders, ointments, creams, gels, lotions, and / or drops) , mucosal, nasal, buccal, enteral, vitreal, intratumoral, sublingual, intranasal; by intratracheal instillation, bronchial instillation, and / or inhalation; as an oral spray and / or powder, nasal spray, and / or aerosol, and / or through a portal vein catheter. Preferred means of administration are intravenous or subcutaneous. “Intermittent” administration is treatment that is not consecutively done without interruption, but rather is cyclic in nature.
[0341] The term “targeted delivery” or the verb form “target” as used herein refers to the process that promotes the arrival of a delivered agent (such as a therapeutic payload molecule in a lipid nanoparticle composition as described herein) at a specific organ, tissue, cell and / or intracellular compartment (referred to as the targeted location) more than any other organ, tissue, cell or intracellular compartment (referred to as the non-target location) . Targeted delivery can be detected using methods known in the art, for example, by comparing the concentration of the delivered agent in a targeted cell population with the concentration of the delivered agent at a non-target cell population after systemic administration. In certain embodiments, targeted delivery results in at least 2 fold higher concentration at a targeted location as compared to a non-target location.
[0342] An “effective amount” is generally an amount sufficient to reduce the severity and / or frequency of symptoms, eliminate the symptoms and / or underlying cause, prevent the occurrence of symptoms and / or their underlying cause, and / or improve or remediate the damage that results from or is associated with a disease, disorder, or condition, including, for example, infection and neoplasia. In some embodiments, the effective amount is a therapeutically effective amount or a prophylactically effective amount.
[0343] The term “therapeutically effective amount” as used herein refers to the amount of an agent (e.g., a vaccine composition) that is sufficient to reduce and / or ameliorate the severity and / or duration of a given disease, disorder, or condition, and / or a symptom related thereto (e.g., an infectious disease such as caused by viral infection, or a neoplastic disease such as cancer) . A “therapeutically effective amount” of a substance / molecule / agent of the present disclosure (e.g., the lipid nanoparticle composition as described herein) may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the substance / molecule / agent to elicit a desired response in the individual. A therapeutically effective amount encompasses an amount in which any toxic or detrimental effects of the substance / molecule / agent are outweighed by the therapeutically beneficial effects. In certain embodiments, the term “therapeutically effective amount” refers to an amount of a lipid nanoparticle composition as described herein or a therapeutic or prophylactic agent contained therein (e.g., a therapeutic mRNA) effective to “treat” a disease, disorder, or condition, in a subject or mammal.
[0344] A “prophylactically effective amount” is an amount of a pharmaceutical composition that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing, delaying, or reducing the likelihood of the onset (or reoccurrence) of a disease, disorder, condition, or associated symptom (s) (e.g., an infectious disease such as caused by viral infection, or a neoplastic disease such as cancer) . Typically, but not necessarily, since a prophylactic dose is used in subjects prior to or at an earlier stage of a disease, disorder, or condition, a prophylactically effective amount may be less than a therapeutically effective amount. The full therapeutic or prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a therapeutically or prophylactically effective amount may be administered in one or more administrations.
[0345] As used herein and unless otherwise specified, the terms “treat” , “treating” , and “treatment” refer to an alleviation, in whole or in part, of a disorder, disease or condition, or one or more of the symptoms associated with a disorder, disease, or condition, or slowing or halting of further progression or worsening of those symptoms, or alleviating or eradicating the cause (s) of the disorder, disease, or condition itself.

[0599] EXEMPLIFICATION
[0600] In order that the present disclosure may be more fully understood, the following examples are set forth. The synthetic and biological examples described in this application are offered to illustrate the compounds, pharmaceutical compositions, and methods provided herein and are not to be construed in any way as limiting their scope.
[0601] Example 1: In vivo gene editing of HSPCs with LNPs comprising ABE8e mRNA and sgRNA
[0602] This example describes in vivo adenine base editing of the HBG locus in the mouse BM cells, according to the presence of the SpCas9 NGG protospacer adjacent motif (PAM) sequence and the human HBG promoter regions, all possible sgRNAs (n=92) within 500 bp upstream of the human HBG promoter regions, which could approach saturation mutagenesis in situ at each genomic position were designed, and 40 sgRNAs were selected preliminarily, four sgRNAs (sgRNA-22 (SEQ ID NO. 12) , sgRNA-35 (SEQ ID NO. 3) , sgRNA-41 (SEQ ID NO. 4) , sgRNA-25 (SEQ ID NO. 1) , sgRNA-26 (SEQ ID NO. 2) ) were selected finally. In this example, the sgRNA-25 (SEQ ID NO. 1) was used.
[0603] Human CD34+ HSPCs (provided by Shanghai Bangyao Biological Technology Co., Ltd. ) were obtained from healthy donors and engrafted into immunodeficient NCG-X mice (purchased from GemPharmatech) . The CD34+ HSPCs were thawed on day 0 in X-VIVO 15 (Lonza, 04-418Q) supplemented with 100 ng ml-1 SCF, 100 ng ml-1 human thrombopoietin (TPO) , and 100 ng ml-1 recombinant human Flt3-ligand (Flt3-L) . The NCG-X mice were administered granulocyte colony-stimulating factor (GCSF) for 5 consecutive days before the initial dosing, and plerixafor was injected subcutaneously on the dosing day.
[0604] In this example, the LNPs was LNP-028, which contain ionizable cationic lipid compound (028) (corresponding to compound 31 in PCT / CN2023 / 100791) . After a 16-week period, the immunodeficient NCG-X mice which support human hematopoietic engraftment without conditioning therapy were administered LNP-ABE8e genome editing system (the LNP formulated with ABE8e mRNA and sgRNA-25) via tail vein injection using different dosage regimens (Fig. 1a) , and every dosage is 1.5 mg / kg. For intravenous administration, three different doses (dose, re-dose, and fifth-dose) of LNPs were administered in adult NCG-X mice. The mice were injected with LNPs every two weeks until the end of five injections.
[0605] As a control, a cohort of separate mice were injected with PBS buffer. There were three animals in each LNP-ABE8e group (n=3) . One week after the last administration of the LNP or control, mice were euthanized and bone marrow cells were harvested and processed for flow cytometry with the indicated markers.
[0606] Fig. 1a-1n depict in vivo adenine base editing of the HBG locus in the mouse BM cells. Fig. 1a depicts Workflow of intravenous (i. v. ) administration of LNPs with co-encapsulated ABE8e mRNA and sgRNA-25. Fig. 1b depicts the average editing efficiencies of 11.0% (A5, 10.8-11.6%) and 8.4% (A6, 7.5-9.9%) in the non-mobilized group compared to 9.0% (A5, 8.5-10.0%) and 7.0% (A6, 5.8-7.6%) in the mobilized group. As shown in Fig. 1c, a significant induction of γ-globin (mean 22.2%in the non-mobilized group and 21.8%in the mobilized group) was observed. As shown in Fig. 1d-1e, BM was collected after LNP-ABE8e treated and analyzed by flow cytometry for human cell chimerism , and multilineage reconstitution in the BM, similar levels of human lymphoid and myeloid engraftment were observed between the mock and LNPs infusion groups. Based on these results, it can be concluded that the editing efficiency and induction level of γ-globin were similar between the non-mobilized group and the mobilized group, thus selecting the non-mobilized approach for subsequent in vivo treatment. Re-dosing (2nd dose) and fifth-dose further increased editing rates to 18.8%and 45.5%at A5, respectively (A6, mean 15.3%for re-dose and 39.3%for fifth-dose; Fig. 1f) .
[0607] Notably, γ-globin mRNA levels were further elevated (mean 31.4%for re-dose and 42.6%for fifth-dose, compared to 2.5%in the mock; Fig. 1g) . Comparable human lymphoid and myeloid engraftment was observed between the edited and unedited groups (Fig. 1h, i) . Analysis of BM cells using FACS revealed effective editing of erythroid cells similar to other lineages (mean 24.7%for A5 re-dose, 20.5%for A6 re-dose; mean 50.0%for A5 fifth-dose, 44.4%for A6 fifth-dose; Fig. 1j, k) .
[0608] In human erythroid cells from the BM, we observed effective editing rates and robust induction of γ-globin at similar levels as BM cells after LNPs editing (Fig. 1l, m) . After LNP-ABE8e base editing, we observed efficient enucleation of terminal enucleated erythroid cells from the BM cell in NCG-X mice (Fig. 1n) .
[0609] In summary, the data showed that LNP-ABE8e, as a non-viral delivery platform, can efficiently edit BM cells and increase the expression level of γ-globin in a humanized mouse model, thus proving to be an effective approach for in vivo induction of therapeutic γ-globin production.
[0610] Example 2: In vivo therapeutic base editing of BM reconstituted from HSPCs of a β-thalassemia patient.
[0611] To get more efficient BM delivery, the structural of ionizable lipid components in LNP were optimized, three variants named LNP-115 which contain ionizable cationic lipid compound (115) (corresponding to compound 15 in PCT / CN2023 / 116607) , LNP-168 which contain ionizable cationic lipid compound (168) (corresponding to compound 18 in PCT / CN2023 / 100791) and LNP-217 which contain ionizable cationic lipid compound (217) (corresponding to compound 1 in PCT / CN2023 / 116607) were developed.
[0612] In this example, intravenous injections of the formulated LNP-ABE8e into C57BL / 6 mice (purchased from GemPharmatech) for in vivo evaluation were conducted, the mPCSK9-sgRNA (SEQ ID NO. 5) was used, Total BM cells were isolated and subjected to evaluate the editing efficiency (Fig. 2a) .
[0613] we successfully formulated LNPs containing ABE8e mRNA and chemically modified sgRNA targeting mPCSK9 locus in a 1: 1 weight ratio, allowing us to achieve in vivo genome editing therapy by targeting the BM with LNPs, the LNPs-ABE8e were administered through tail vein injection in wild-type C57BL / 6J mice and conducted an initial evaluation of the in vivo editing effect of LNP-028 in BM cells. After a single injection of LNP-ABE8e, the average editing efficiency targeting the mPCSK9 locus was 10.7%, increasing the number of administrations resulted in a further increase in editing efficiency to 20.2%, LNP-168 exhibited the highest efficiency in base editing within BM cells, achieving an editing efficiency nearly 40.0%with just two injections compared to LNP-028 (Fig. 2b) . This is suggestsed that LNP-168 had significant potential as a delivery vehicle for ABE8e mRNA and sgRNA.
[0614] As shown in Fig. 3a, transplantation of β-thalassemia patient-derived CD34+ HSPCs into immunodeficient NCG-X mice, followed by intravenous administration of LNP-168-ABE8e to demonstrate phenotypic rescue in vivo, with two doses of intravenous administration of LNP-168-ABE8e, the average base edit frequency at the target HBG promoter was measured (Fig. 3a) .
[0615] Notably, with two doses of intravenous administration of LNP-ABE8e, the average base edit frequency at the target HBG promoter achieved 42.6%, accompanied by potent induction of γ-globin in BM cells (Fig. 3b, c and Fig. 4) .
[0616] The majority of BM cells in the recipient mice were human cells expressing the CD45 hematopoietic antigen, indicating that the proportion of human cells in the BM was not affected by LNP-168-ABE8e (Fig. 3d) . In addition, in vivo genome editing also had no effect on the proportion of myeloid and B-cells in the BM (Fig. 3e) . The base editing rate at the HBG promoter remained consistent in erythroid cells differentiated from HSPCs edited by LNP-168-ABE8e, indicating that in vivo genome editing did not affect erythrocyte differentiation (Fig. 3b) . In human erythroid cells derived from the BM, robust induction of γ-globin was observed after editing (mean increase from 0.14 to 0.6 relative to α-globin; Fig. 3f) . Following base editing, higher enucleation efficiency, increased cell size, and a more circular shape in enucleated erythroid cells was observed, suggesting the restoration of the morphology of erythroid cells in patients with β-thalassemia following in vivo genome editing (Fig. 3g-i) .
[0617] In summary, the data showed that the use of the LNP-168-ABE8e in vivo genome editing system allows for efficient base editing, thereby inducing sufficient γ-globin expression to rescue the hematological phenotype of β-thalassemia.
[0618] And in this example, LNP-183 contain ionizable cationic lipid compound (183) was also used, and the result shows efficient base editing, the base editting frequency is not shown.

The ABE8e mRNA and gRNA cargo in a 1: 1 ratio was encapsulated in a lipid nanoparticle through an ethanol-drop nanoprecipitation process. Briefly, lipids (proprietary ionizable cationic lipid: 1, 2-distearoyl-sn-glycero-3-phosphocholine, cholesterol, and a PEG-lipid) were rapidly mixed using Precision NanoSystems NanoAssemblr Benchtop Instrument with mRNA in citrate buffer, pH 5.0, at an N: P ratio 4.5. The RNA-loaded dispersions were neutralized by buffer exchanged into phosphate-buffered saline (PBS) , pH 7.4, and filtered using a 0.2-um sterile filter. Formulated LNP was then vialed and stored refrigerated at 4℃ until further use. Encapsulation efficiencies were determined by Quant-iT Ribogreen assay (Life Technologies) .
