Abstract
Description
Novel ionized lipids and lipid nanoparticle compositions using the same
[0001] The present invention relates to a novel ionized lipid, a lipid nanoparticle composition using the same, and uses thereof.
[0002] Nucleic acid-based medicines are being used not only as therapeutic agents, but also as preventative agents that protect against diseases by injecting genes that can express antigens for specific diseases. Gene-based vaccines are categorized into DNA vaccines, RNA vaccines, and viral vector vaccines. Among them, RNA vaccines inject mRNA encoding an antigen into the body, causing the antigen to be expressed in the body and inducing antibody formation. RNA vaccines do not have the potential risks of infection associated with viral vector-based vaccines or genetic mutation associated with DNA vaccines. Furthermore, they can be developed quickly, drawing attention as an effective response to the COVID-19 outbreak in 2019.
[0003] However, genes are easily degraded by nucleases in the human body and are negatively charged macromolecules that are not easily delivered into cells. Therefore, a method for delivering them stably and efficiently to the desired location is needed. Various delivery techniques based on materials such as lipids, polymers, dendrimers, and inorganic metal materials have been reported as gene delivery systems. Among these, lipid nanoparticles as lipid delivery vehicles were the first siRNA new drug to receive FDA approval in 2018, patisiran (ONPATTRO). ® ) and after being applied to the development of the mRNA vaccine for COVID-19, which was approved for emergency use in 2020, lipid nanoparticle technology has been recognized for its technological value as a clinically useful delivery system for nucleic acid drugs such as siRNA and mRNA.
[0004] Current lipid nanoparticles are generally used in a form in which four components are mixed in a certain ratio: ionized lipid, phospholipid (helper lipid), cholesterol (structure-maintaining lipid), and PEG-lipid. However, as the development of gene therapy for various indications is in full swing, unmet needs have been identified in various aspects such as enhanced gene delivery ability, maintenance of gene delivery ability in specific diseases such as liver disease, enhanced stability, improved targeting characteristics, ensuring ease of storage and distribution, mitigation of side effects, cost reduction, and response to breakthrough infection. Therefore, the development of lipid nanoparticles using new ionized lipid delivery systems is continuously required.
[0005] Systemic administration of lipid nanoparticles can be utilized in the development of gene therapy. However, most lipid nanoparticles have problems with gene delivery capacity being reduced and not maintained when re-administered to maintain the therapeutic efficacy. Therefore, the development of novel ionizable lipid carriers to address this issue is needed. Local administration of lipid nanoparticles can be utilized in the development of mRNA vaccines or topical therapeutics. However, in this case, unnecessary systemic exposure of lipid nanoparticles can lead to adverse effects. Therefore, the development of ionizable lipid carriers with high local protein expression rates is required.
[0006] As gene therapy enters the pharmaceutical market in the future and continues to expand, it is expected that by securing various ionized lipids different from the existing ionized lipids and developing new lipid nanoparticle systems using them, gene delivery ability will be further improved and unmet needs for systemic or repeated administration will be addressed, thereby enabling the development of gene therapy for numerous rare diseases and various mRNA vaccines and cancer vaccines.

TMAfter adding 100 μL of RNA Reagent and mixing, the fluorescence intensity (excitation 475 nm and emission 500-550 nm) was measured to create a calibration curve. 5 μL of the nanoparticle solution prepared in Example 2 was diluted with 245 μL of TE buffer (10 mM Tris-HCl, 1 mM EDTA, pH 7.5 in DEPC-treated water). 50 μL of TE buffer or 2% Triton-TE buffer was added to 50 μL of the diluted nanoparticle solution, and incubated at 37°C for about 10 minutes. 40 μL of each culture medium was then placed in a microplate, and 60 μL of TE buffer and Quant-iT were added. TM Ribogreen TM 100 μL of RNA reagent was sequentially added, mixed, and the fluorescence intensity was measured. The measured fluorescence intensity was applied to the calibration curve to calculate the gene content in TE buffer (TO) and in 2% Triton-TE buffer (T2).

[0255] <Analysis Example 3> Confirmation of lipid nanoparticle gene delivery efficiency
[0256] 3-1. Confirmation of intracellular gene transfer efficiency
[0257] In order to confirm the intracellular gene delivery efficiency of lipid nanoparticles including the compound of Example 1, the reporter gene FLuc mRNA was encapsulated in lipid nanoparticles and its intracellular expression efficiency was evaluated. Since lipid nanoparticles mediate the low-density lipoprotein receptor (LDL receptor), a cell surface receptor, as a cellular uptake mechanism, HeLa cell line (Korea Cell Line Bank, Seoul), a human cervical cancer cell line with high expression of LDL receptor on the cell surface, was used, and cell culture was performed using MEM (minimum essential medium) medium (Gibco) containing 10% fetal bovine serum (Gibco, NY, USA) and penicillin / streptomycin (Gibco) at 37°C and 5% CO2 conditions. Before lipid nanoparticle treatment, HeLa cell line was seeded at 2 × 10 per well. 4 Cells were cultured in 96-well plates, and after stabilization for 16 to 24 hours, lipid nanoparticles at a concentration of 0.25 μg / mL based on the encapsulated mRNA were diluted in cell culture medium and treated to the cells.
[0258] To confirm the expression of intracellular luciferase, 6 hours after lipid nanoparticle treatment, the culture medium in the wells was removed, washed with PBS, and 100 μL of Glo-Lysis Buffer (Promega, WI, USA) was added to lyse the cells at room temperature for 5 minutes. Next, 50 μL of each cell lysate and Steady-Glo™ Luciferase Assay solution (Promega) were added at a 1:1 ratio to a 96-well white plate, and after incubation at room temperature for 5 minutes, the luminescence value was detected using a GloMax Discover microplate reader (Promega). A calibration curve was created using recombinant luciferase (Promega) as a standard, and the luciferase protein concentration (pg / mL) of the cell lysate was derived from this.
[0259] As a result, as shown in Table 3 below, it was confirmed that lipid nanoparticles including the compound of Example 1 exhibited good gene delivery efficacy into cells.

[0261]
[0262] 3-2. Confirmation of in vivo gene transfer efficiency 1
[0263] In order to confirm the in vivo gene transfer efficiency of lipid nanoparticles including the compound of Example 1, lipid nanoparticles were intravenously injected once at a dose of 1 mg / kg based on the luciferase gene loaded into 7-week-old C57BL / 6 mice, and after 4 hours, the mice were sacrificed and their livers were removed.
[0264] To determine the level of luciferase expression in liver tissue samples, the excised liver tissue was transferred to a tube containing 3 mm metal beads, 500 μL of Glo-Lysis Buffer (Promega) per 50 mg was added, and the tissue was homogenized using a bead homogenizer. The homogenate was centrifuged at 1,000 g for 10 minutes, and the supernatant was diluted to an appropriate ratio using Glo-Lysis Buffer. The diluted tissue homogenate and Steady-Glo Luciferase Assay (Promega) solution were each transferred to a 96-well white plate at a 1:1 ratio, and reacted at room temperature for 5 minutes. Next, the luminescence value was detected using a GloMax Discover microplate reader (Promega), and a calibration curve was generated using recombinant luciferase (Promega) as a standard, through which the luciferase expression level of the sample (ng / g tissue) was derived.
[0265] As a result, as shown in Table 4 below, the lipid nanoparticles containing the compound of Example 1 exhibited high levels of luciferase expression in liver tissue upon intravenous injection, thereby confirming their function as a gene delivery vehicle with excellent delivery efficacy in the body through systemic administration. In addition, in an in vivo test, composition B showed similar or higher delivery efficacy compared to composition A.

[0267]
[0268] 3-3. Confirmation of in vivo gene transfer efficiency 2
[0269] To determine the in vivo gene transfer efficiency of repeated administration of lipid nanoparticles, 7-week-old C57BL / 6 mice were intravenously injected with lipid nanoparticles loaded with EPO mRNA (TriLink BioTechnologies, CA, USA) at a dose of 0.5 mg / kg per gene. Blood samples were collected 6 hours after lipid nanoparticle administration, and plasma was separated by anticoagulation.
[0270] To determine the concentration of EPO protein expressed in plasma, an EPO enzyme-linked immunosorbent assay (ELISA) kit (R&D Systems, MN, USA) was used for analysis according to the manufacturer's method. More specifically, plasma samples were diluted 1:5000 using the specimen diluent included in the kit, mixed with 100 μL of assay diluent in a 1:1 ratio in microwells, and incubated for 2 hours at room temperature. After removing all the solution in each well, 200 μL of EPO conjugate was added, and incubated for another 2 hours at room temperature. After washing four times with 300 μL of washing buffer, 200 μL of substrate solution was added, and incubated for 20 minutes. To terminate the reaction, 100 μL of stop solution was added, and the absorbance was measured at wavelengths of 450 nm and 600 nm using a microplate reader (Promega). A calibration curve was prepared using the standard material provided in the kit, and the EPO protein concentration (ng / mL) of each sample was calculated within the defined range of the standard material.
[0271] As a result, as shown in Table 5 below, the lipid nanoparticles including the compound of Example 1 showed a higher level of EPO expression in the blood compared to the lipid nanoparticles including the ionized lipid Lipid 5 used as a control during repeated intravenous injections, and when administered again, it was confirmed that, unlike the Lipid 5 lipid nanoparticles, the lipid nanoparticles including the compound of Example 1 maintained a high level of EPO expression well. Considering that Lipid 5 is known to be a carrier that maintains a good gene delivery ability during repeated administration among carriers to date, it can be confirmed that the compound of Example 1 has characteristics that are advantageous for repeated administration.
