Description

Composition containing selective long-term target lipids

[0001] The present invention relates to a composition comprising a selective organ-targeting lipid capable of controllingly delivering nucleic acids to a target tissue. More specifically, the present invention relates to a composition comprising a selective organ-targeting lipid that targets the spleen or immune cells.

[0002] Although active research is being conducted to prevent or treat diseases by delivering nucleic acids into the body, such as RNA inhibitors, antisense oligonucleotides (ASOs), short interfering RNA (siRNA), aptamers, messenger RNA (mRNA), self-amplifying RNA (SAM), and circular RNA, nucleic acids have the disadvantage of being easily degraded in the blood by enzymes in the body, such as RNase and nuclease. Furthermore, among nucleic acids, mRNA, which has a long length of more than 500 nucleotides, has a large molecular weight of more than 200 kDa, making it difficult to deliver nucleic acids to target cells in the body, and the negative charge of nucleic acids is a factor that hinders the delivery of nucleic acids to target cells in the body.

[0003] Accordingly, the importance of lipid nanoparticles (LNPs) is increasing as drug delivery systems designed to safely deliver nucleic acids to target cells or tissues by stably delivering them into the body while preventing degradation by endogenous enzymes. Lipid nanoparticles contribute to delivering nucleic acids into cells by penetrating the cell membrane; recently, mRNA-based COVID-19 vaccines (Spikevax TM , Comirnaty TM Lipid nanoparticles were also used in the development process.

[0004] However, while lipid nanoparticles are a clinically safe and effective mature technology for delivering genetic medicines, intravenously administered lipid nanoparticles generally accumulate in the liver and target hepatocytes, severely limiting their therapeutic application; therefore, the development of nucleic acid delivery systems capable of extrahepatic targeting is necessary.

[0005] Conventional lipid nanoparticles consist of a total of four lipids: ionizable lipid, phospholipid, cholesterol, and PEG-lipid. It is known that adding a fifth component (Selective Organ Targeting lipid, SORT lipid) to the existing four components for mRNA delivery to the liver alters the in vivo organ targeting characteristics of lipid nanoparticles, resulting in mRNA delivery to tissues other than the liver. Phosphate lipids, which carry a negative charge, are representative Selective Organ Targeting lipids for spleen delivery.

[0109] Embodiments of the present invention will be described in detail below. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings. Instead, based on the principle that the inventor can appropriately define the concepts of terms to best describe their invention, they should be interpreted in a meaning and concept consistent with the technical spirit of the present invention. Therefore, the configurations described in the embodiments of this specification are merely one preferred embodiment of the present invention and do not represent all aspects of the technical spirit of the present invention. It should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application.

[0110] Throughout this specification, when a part is described as 'comprising' a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0111] Furthermore, descriptions that specify components by limiting or adding them may be applied to all inventions unless there are special limitations, and are not limited to specific inventions.

[0112] In addition, throughout the description of the invention and claims of this application, items indicated in the singular include cases where they are plural unless otherwise noted.

[0113] In addition, throughout the description of the invention and the claims of the present invention, "or" includes "and" unless otherwise noted. Therefore, "comprising A or B" means all three of the above cases: including A, including B, or including both A and B.

[0114] In addition, all numerical ranges include the values ​​at both ends and all intermediate values ​​in between, unless explicitly stated to be excluded.

[0115] In this specification, the term "lipid nanoparticle (LNP)" refers to a structure in which a homogeneous phase is prepared by mixing lipids with a drug (e.g., a nucleic acid-based drug) at room temperature and dispersing it in an aqueous solution, so that the drug exists as a solid solution between lipid crystals. Since the lipid nanoparticles utilize substances present in the body such as phospholipids, lipids, and cholesterol, they have high bioavailability and affinity, enable drug release and control, and are particulate drug delivery systems with high stability against degradation by enzymes. Additionally, the lipid nanoparticles can encapsulate RNA by being positively charged at acidic pH, and can minimize toxicity by being neutrally charged at physiological pH.

[0116]

[0117] In one aspect of the present invention, the composition of the present invention provides a composition comprising an ionizable lipid, a selective organ targeting lipid, cholesterol, and a polyethylene glycol lipid. In another aspect of the present invention, the composition may further comprise a helper lipid.

[0118] Ionized lipids are generally composed of an ionizable head, a linker, and a terminal consisting of a hydrocarbon chain. They are known to play a key role in determining nucleic acid delivery efficiency by electrostatically binding to nucleic acids to encapsulate them and enabling the escape of nucleic acids from endosomes within the cell. Additionally, cholesterol maintains lipid nanoparticles in a rigid and stable manner, while PEG lipids prevent aggregation between lipid nanoparticles and ensure structural stability. Furthermore, helper lipids (e.g., phospholipids) play a role in maintaining the lipid bilayer structure of lipid nanoparticles.

[0119] Selective organ-targeted lipids are a critical component in the design of lipid nanoparticles that can enhance therapeutic efficacy and reduce side effects by selectively targeting specific organs or tissues to deliver therapeutic agents. Selective organ-targeted lipids are often chemically modified to contain target portions, such as ligands or antibodies, that can specifically bind to receptors or other markers unique to specific cells or tissues; this specificity ensures that lipid nanoparticles accumulate preferentially in target organs. In addition to their targeting function, these lipids help form a stable bilayer structure for the lipid nanoparticles. They can be customized to adjust nanoparticle size, charge, and stability, which are critical factors for circulation time and bioavailability. Furthermore, the design of selective organ-targeted lipid nanoparticles can influence how they interact with cell membranes, facilitating the fusion or endocytosis necessary for cell entry, and can aid in the release of therapeutic payloads from the lipid nanoparticles into the cytoplasm once inside the target cell.

[0120] In one embodiment of the present invention, the ionized lipid may be a lipid comprising 1 to 10 nitrogen atoms and 1 to 10 biodegradable bonds. The biodegradable bonds refer to chemical bonds that can be hydrolyzed or degraded by enzymes, water, or under specific pH conditions in vivo, and specifically may be ester bonds, amide bonds, or disulfide bonds, but are not necessarily limited thereto.

[0121] In one embodiment of the present invention, the ionized lipid may be a lipid comprising 1 to 8 nitrogen atoms and 1 to 9 biodegradable bonds, or a lipid comprising 1 to 5 nitrogen atoms and 1 to 8 biodegradable bonds. In one embodiment of the present invention, the biodegradable bond may be an ester bond.

[0122] In one embodiment of the present invention, the ionized lipid comprises a pyrazole structure or a diazabicyclo structure and may comprise one to ten ester bonds. The pyrazole structure refers to an aromatic heterocycle comprising two nitrogen atoms not adjacent to the 1,2-position within the ring. Additionally, the diazabicyclo structure refers to a bicyclic structure comprising two nitrogen atoms. The number of ester bonds may be one to ten, one to nine, or one to eight.

[0123] In one embodiment of the present invention, the ionized lipid may be one or more compounds selected from the group consisting of the following. Additionally, the ionized lipid may refer to the compounds described in Korean Patent Applications No. 10-2023-0143205 and No. 10-2023-0143867:

[0266] [Method for Analyzing the Physicochemical Properties of the Composition]

[0267] The particle size, z-average diameter, and polydispersity index (PDI) were analyzed using Zetasizer Pro (Malvern Instruments, United Kingdom). Measurements were taken with a 1X DPBS dilution. The "PDI" is a ratio describing the homogeneity of the particle size distribution of the system; a PDI closer to 0 indicates monodispersity, while a PDI closer to 1 indicates polydispersity.

[0268] [MRNA Quantification and Encapsulation Efficiency (EE %) Measurement Method]

[0269] To measure mRNA content and encapsulation efficiency, a Ribogreen RNA assay kit (Invitrogen, USA) was used. Standard solutions ranging from 0 to 1000 ng / mL were prepared using ribosomal RNA, and samples were diluted to fall within this range. 50 μL of the sample or standard solution was loaded into 96-well microplates, followed by 50 μL of 1X TE buffer or 1% TritonX-100 solution. The plates were then incubated at room temperature for 10 minutes. After loading 100 μL of Ribogreen reagent solution diluted to a ratio of 1 / 200, fluorescence was measured using a microplate reader (Enspire 2300, PerkinElmer, USA) (Excitation 485 nm, Emission 530 nm).

[0270] The z-average diameter and PDI of the prepared composition are shown in Fig. 1, and the EE (%) is shown in Fig. 2.

[0271] The composition containing the present invention's selective organ-targeted lipids was found to have a z-average diameter of 300 nm or less and a narrow particle size distribution with a PDI of less than 0.2.

[0272]

[0273] Experimental Example 2. Expression efficiency in the spleen following intravenous administration of a composition containing selective organ-targeted lipids

[0274] To evaluate drug delivery distribution and in vivo transfection efficiency after systemic administration of the prepared substance, the composition of Experimental Example 1 was injected into Balb / c mice (male, 6 weeks old) via tail vein injection (administration volume 200 μL). 6 hours after injection, 150 mg / kg of D-Luciferin (Perkin Elmer, USA) was administered intraperitoneally, and 10 minutes later, luminescence in major organs (lungs, liver, spleen) was measured using IVIS Luminar XR (Perkin Elmer, USA).

[0275] In relation to Comparative Example 1 and Examples 1 to 31, the expression rate of luminescent firefly luciferase protein in the spleen is shown in FIG. 3, and in relation to Comparative Examples 2 to 7 and Examples 1 to 5, 9 to 13, 17 to 21, and 23 to 31, the expression efficiency and presence or absence of luminescent firefly luciferase protein in the lungs, liver, and spleen are shown in FIG. 4 and FIG. 5. In FIG. 5, photographs of each organ correspond to the lungs, liver, and spleen in order from left to right.

[0276] As confirmed in FIGS. 3 to 5, the composition of the present invention showed superior expression efficiency in the spleen compared to the comparative example that did not contain the selective organ target lipid of the present invention.

[0277]

[0278] Experimental Example 3. Expression efficiency in lung immune cells following intratracheal administration of a composition containing selective organ-targeted lipids

[0279] To evaluate drug delivery distribution and in vivo transfection efficiency following intratracheal administration of the prepared substance, the composition of Experimental Example 1 was injected into Balb / c mice (male, 6 weeks old) via intratracheal injection. Eight hours after administration, the mice were euthanized, and the lungs were perfused through the right ventricle to remove red blood cells and circulating leukocytes. The mouse lungs were then dissected into individual lobes, and washed in a Petri dish containing pH 7.2 PBS to remove any remaining blood. After removing the thymus, heart, blood vessels, bronchi, and connective tissues of the lung tissues, the dissected lung lobes were transferred to gentle MACS C tubes containing a prepared enzyme mixture. The enzyme mixture was prepared by adding 1× Buffer S, Enzyme D, and Enzyme A to the gentle MACS C tubes, and the enzyme solution was slowly injected into each lung lobe to induce dilation. Subsequently, the program was executed after attaching a gentle MACS Dissociator. After the program ended, Tube C was separated from the Dissociator, and the resuspended sample was filtered through a MACS Smart Strainer, centrifuged for 10 minutes, and the supernatant was removed. Subsequently, Debris Removal Solution was added to allow PBS to form a layer over the cell suspension, and the sample was centrifuged to completely remove the supernatant. Then, RBCs were removed using 1x RBC Lysis Buffer, followed by a wash with buffer. To confirm cell-specific expression, antibodies (Invitrogen, L34957), Anti-CD45-BV786 (BD, 564225), Anti-Ep-CAM (CD326)-BV605 (Biolegend, 118227), CD31-PE-Cy7 (ebioscience, 25-0311-82), Anti-Ly6G-PE (BD, 551461), and Anti-Siglec-F-PerCP-Cy5 were used.After staining with 5 (BD, 565526), ​​Anti-CD11b-APC-Cy7 (BD, 557657), Anti-MHCII-AF700 (Invitrogen, 56-5321-82), Anti-CD11c-V450 (BD, 560521), Anti-CD24-BV711 (BD, 563450), Anti-CD64-FITC (Biolegend, 139316), and Anti-F4 / 80-APC (Invitrogen, 17-4801-82), the cells were analyzed using a FACs instrument (BD FAC Symphony™ A5 Cell Analyzer) and are shown in Figures 6a to 6h.

[0280] Specifically, the expression efficiency of lung immune cells was confirmed following intratracheal administration of PBS (DPBS (Dulbecco's Phosphate-Buffered Saline)) and each experimental example as a control group indicated on the x-axis of Figures 6a to 6h, and the expression efficiency was confirmed in order in alveolar macrophages, neutrophils, B cells, T cells, monocytes, NK cells, dendritic cells (DC), and eosinophils.

[0281] As confirmed in FIGS. 6a to 6h, the composition of the present invention showed superior expression efficiency in lung immune cells compared to a comparative example that did not contain the selective organ-targeted lipid of the present invention.
