Description

Lipid nanoparticles with improved genetic material transfer efficiency through extracellular matrix regulation and pH regulation of intracellular organelles, and their uses

[0001] The present invention relates to lipid nanoparticles with improved genetic material delivery efficiency through the regulation of the extracellular matrix and the pH of intracellular organelles, and to the uses thereof. More specifically, the invention relates to a composition for delivering genetic material capable of increasing genetic material delivery efficiency by including a hydrogen pump inhibitor to increase the cellular uptake rate of lipid nanoparticles through the regulation of the extracellular matrix and inducing effective endosome / lysosome escape of genetic material through the regulation of the function of acidic organelles in the cell.

[0002] Genetic materials such as mRNA and DNA are biomolecules that present limitations: they are easily degraded by hydrolytic enzymes when injected into the body, and their negative charge makes delivery into cells difficult. Furthermore, once delivered into the cell, genetic material must escape from acidic intracellular organelles—such as endosomes and lysosomes—and migrate to the nucleus or cytoplasm to ultimately lead to the production of target proteins. Consequently, delivery systems utilizing various materials are being developed to protect genetic material from hydrolytic enzymes while simultaneously inducing effective protein expression at desired sites.

[0003] Among genetic material carriers, lipid nanoparticles are a mixture of four components: ionized lipids, phospholipids (helper lipids), cholesterol (structure-maintaining lipids), and lipid-PEG conjugates. They are the most actively researched particles currently being developed due to their high delivery efficiency among developed gene carriers. Nevertheless, it is known that the amount of genetic material that escapes from endosomes / lysosomes after being introduced into cells via lipid nanoparticles is a small amount, approximately 1–2%.

[0004] Accordingly, the inventors have completed the present invention by developing a composition for delivering genetic material that can increase the efficiency of genetic material delivery by increasing the cellular absorption of lipid nanoparticles and inducing the effective escape of genetic material from endosomes / lysosomes.

[0005] The present invention aims to provide a composition for delivering genetic material that can increase the efficiency of genetic material delivery by increasing the cellular absorption of lipid nanoparticles and inducing the effective escape of genetic material from endosomes / lysosomes.

[0006] In addition, the present invention aims to provide a composition for delivering genetic material capable of improving the immune response through enhanced antigen delivery in a cancer vaccine using mRNA.

[0007] In addition, the present invention aims to provide a composition for delivering genetic material applicable to various fields, such as genetic material-based vaccines and genetic material-based therapeutic agents targeting various diseases.

[0008] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are to be illustrated and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. Specific details for the implementation of the above invention are described below.

[0013] The present invention relates to lipid nanoparticles with improved genetic material transfer efficiency through the regulation of the extracellular matrix and the pH of intracellular organelles, and to the uses thereof.

[0014] Specifically, the present invention provides a composition for genetic material delivery comprising: lipid nanoparticles comprising ionized lipids, phospholipids, cholesterol, and lipid-PEG (polyethylene glycol) conjugates; and a hydrogen pump inhibitor.

[0015] Proton pump inhibitors are known to inhibit the activity of hydrogen / potassium pumps in acidic organelles, such as endosomes and lysosomes, thereby inducing membrane permeability by causing dysfunction of these organelles through an increase in internal pH. Additionally, proton pump inhibitors are known to downregulate transforming growth factor beta (TGF-β)-induced fibrillation. Utilizing this, enhanced gene expression was induced by in vivo co-administering lipid nanoparticles encapsulating nucleic acid drugs with proton pump inhibitors. By utilizing the various effects of these hydrogen pump inhibitors (proton pump inhibitors), it is possible to increase the penetration of lipid nanoparticles into tissues through the regulation of the extracellular matrix and to induce the effective escape of genetic material from endosomes and lysosomes by regulating the function of acidic organelles, thereby increasing the efficiency of genetic material delivery.

[0016] In addition, the composition for transferring genetic material according to the present invention may further include genetic material.

[0017] More specifically, the genetic material may be encapsulated within the lipid nanoparticles, and the genetic material may be encapsulated stably and with high efficiency to exhibit an excellent expression effect through the delivery composition. In addition, there is an advantage in that the type of genetic material encapsulated within the lipid nanoparticles can be varied according to the purpose.

[0018] The genetic material may be DNA and / or RNA, and may include an antisense nucleotide, mRNA, siRNA (small interfering RNA), miRNA (microRNA), ssRNA (Single-Stranded RNA), pDNA (plasmid DNA), cDNA (complementary), etc. associated with the genetic material, and preferably may include mRNA or pDNA.

[0019] In this specification, "mRNA" refers to synthetic mRNA capable of gene expression (in vitro transcribed mRNA).

[0020] The above hydrogen pump inhibitor may include one or more selected from the group consisting of esomeprazole, pantoprazole, omeprazole, lansoprazole, rabeprazole, ilaprazole, and dexlansoprazole, and preferably may include one or more selected from the group consisting of esomeprazole, pantoprazole, omeprazole, and rabeprazole.

[0021] The present invention aimed to increase more effective expression in the delivery of genetic material through lipid nanoparticles, and for this purpose, a hydrogen pump inhibitor, specifically esomeprazole (or pantoprazole, omeprazole, rabeprazole), was administered in combination. Enhanced delivery of genetic material is possible through increased cell uptake due to the action of the hydrogen pump inhibitor, along with increased expression of genetic material (mRNA) through the induction of endosome / lysosome dysfunction, and furthermore, increased efficacy of genetic material therapeutic agents is possible.

[0022] In addition, the composition for transferring genetic material according to the present invention may have the hydrogen pump inhibitor encapsulated inside the lipid nanoparticle.

[0023] More specifically, the hydrogen pump inhibitor may be encapsulated inside the lipid nanoparticles together with the genetic material, and this enables enhanced delivery of the genetic material through increased genetic material expression, similar to the mixed administration of lipid nanoparticles containing the genetic material and the hydrogen pump inhibitor.

[0024] Among the components of lipid nanoparticles according to one example, the ionized lipid is an ionizable compound having properties similar to lipids, and can play a role in encapsulating the dielectric material within the lipid nanoparticles with high efficiency through electrostatic interaction with the dielectric material.

[0026] According to one example, the phospholipid, among the components of the lipid nanoparticle, plays a role in protecting the core formed by the interaction of ionized lipids and genetic material (mRNA) within the lipid nanoparticle by enveloping it, and binds to the phospholipid bilayer of target cells to facilitate cell membrane passage and endosomal escape during intracellular drug delivery.

[0028] In this specification, "lipid-PEG (polyethyleneglycol) conjugate," "lipid-PEG," "PEG-lipid," or "lipid-PEG" refers to a form in which lipids and PEG are conjugated, meaning a lipid to which a polyethylene glycol (PEG) polymer, a hydrophilic polymer, is attached to one end. The lipid-PEG conjugate contributes to the stability of the nanoparticles within the lipid nanoparticles in serum and prevents aggregation between nanoparticles. Additionally, the lipid-PEG conjugate can enhance the in vivo stability of nucleic acids by protecting them from degrading enzymes during in vivo delivery.

[0029] The above lipid-PEG conjugate may include one or more selected from the group consisting of PEG-DMG, PEG conjugated to dialkyloxypropyl (PEG-DAA), PEG conjugated to diacylglycerol (PEG-DAG), PEG conjugated to phospholipids such as phosphatidylethanolamine (PEG-PE), PEG conjugated to ceramide (PEG-CER), PEG conjugated to cholesterol or a derivative thereof, PEG-c-DOMG, PEG-DLPE, PEG-DMPE, PEG-DPPC, and PEG-DSPE, and preferably may include PEG-DMG.

[0030] The average molecular weight of the above lipid-PEG conjugate is 100 to 10,000 daltons, 200 to 10,000 daltons, 500 to 10,000 daltons, 1,000 to 10,000 daltons, 1,500 to 10,000 daltons, 2,000 to 10,000 daltons, 100 to 7,500 daltons, 200 to 7,500 daltons, 500 to 7,500 daltons, 1,000 to 7,500 daltons, 1,500 to 7,500 daltons, 2,000 to 7,500 daltons, 100 to 5,000 daltons, 200 to 5,000 daltons, 500 to 5,000 daltons, 1,000 to 5,000 daltons, 1,500 to 5,000 daltons, 2,000 to 5,000 daltons, 100 to 3,000 daltons, 200 to 3,000 daltons, 500 to 3,000 daltons, 1,000 to 3,000 daltons, 1,500 to 3,000 daltons, 2,000 to 3,000 daltons, 100 to 2,600 daltons, 200 to 2,600 daltons, 500 to 2,600 daltons, 1,000 to 2,600 daltons, 1,500 to 2,600 daltons, 2,000 to 2,600 daltons, 100 to 2,500 daltons, 200 to It may be 2,500 daltons, 500 to 2,500 daltons, 1,000 to 2,500 daltons, 1,500 to 2,500 daltons, or 2,000 to 2,500 daltons.

[0031] In the above composition, the concentration of the hydrogen pump inhibitor may be 1 to 250 μg / mL, preferably 3 to 225 μg / mL, 20 to 200 μg / mL, 50 to 175 μg / mL, 100 to 150 μg / mL, more preferably 110 to 140 μg / mL, and even more preferably 120 to 130 μg / mL. If the concentration of the hydrogen pump inhibitor is less than 1 μg / mL or exceeds 250 μg / mL, the effect (increase in mRNA expression within cells) resulting from the composition containing the hydrogen pump inhibitor is negligible and is therefore undesirable.

[0032] The lipid nanoparticles may contain ionized lipids : phospholipids : cholesterol : lipid-PEG conjugates in a molar ratio of 10 to 60 : 5 to 50 : 30 to 50 : 0.5 to 5. Preferably, the lipid nanoparticles may contain ionized lipids : phospholipids : cholesterol : lipid-PEG conjugates in a molar ratio of 15 to 55 : 8 to 42 : 35 to 45 : 0.8 to 3, and more preferably in a molar ratio of 20 to 50 : 10 to 40 : 37 to 40 : 1 to 2. The molar ratio of the components can be maintained by decreasing the molar amount of phospholipids by the amount by which the molar amount of ionized lipids is increased, while keeping the sum of the molar amounts of ionized lipids and phospholipids among the components included in the lipid nanoparticles constant.

[0033] In this specification, the molar ratio refers to the mole ratio.

[0034] The lipid nanoparticles may have an average diameter of 50 to 200 nm, preferably 60 nm to 180 nm, 70 nm to 150 nm, 80 nm to 120 nm, and more preferably 90 nm to 100 nm.

[0035] If the size of the lipid nanoparticles is smaller than the lower limit of the above range, (i) the binding of lipid nanoparticles to apolipoproteins (e.g., ApoE (e.g., ApoE3)) present in the blood during systemic circulation may be reduced, thereby reducing the number of lipid nanoparticles entering the cell, and / or (ii) the surface area of ​​the lipid nanoparticles may be excessively increased, making it difficult to maintain stability, and consequently, the efficiency of genetic material delivery to target tissues (or target cells) and / or the therapeutic effect of the genetic material carried by the lipid nanoparticles may be reduced.

[0036] Lipid nanoparticles having a diameter within the above range have superior drug delivery efficiency to target organs and / or cells compared to lipid nanoparticles having a diameter exceeding the upper limit of the above range.

[0037] In this specification, "encapsulation" refers to encapsulating a delivery substance to efficiently incorporate it into the body, genetic material encapsulation efficiency (encapsulation efficiency) refers to the content of genetic material encapsulated within lipid nanoparticles relative to the total content of genetic material used in preparation, and hydrogen pump inhibitor encapsulation efficiency refers to the content of hydrogen pump inhibitor encapsulated within lipid nanoparticles relative to the total content of hydrogen pump inhibitor used in preparation.

[0038] The dielectric material encapsulation efficiency of the above-mentioned dielectric material delivery composition may be 70% or more, 75% or more, 80% or more, 85% or more, 86% or more, 87% or more, 88% or more, 89% or more, greater than 80% to 99% or less, greater than 80% to 97% or less, greater than 80% to 95% or less, 85% or more to 95% or less, 87% or more to 95% or less, 90% or more to 95% or less, 91% or more to 95% or less, or 91% or more to 94% or less.

[0039] When a hydrogen pump inhibitor is encapsulated inside the above lipid nanoparticles, the encapsulation efficiency of the hydrogen pump inhibitor may be 60% or more, 65% or more, 70% or more, 75% or more, 76% or more, 77% or more, 78% or more, 79% or more, greater than 70% to 99% or less, greater than 70% to 97% or less, greater than 70% to 95% or less, greater than 75% to 95% or less, 77% or more to 95% or less, 80% or more to 95% or less, 81% or more to 95% or less, or 81% or more to 90% or less.

[0040] According to one example, the encapsulation efficiency can be calculated by a commonly used method, for example, the dielectric material encapsulation efficiency and the hydrogen pump inhibitor encapsulation efficiency may be measured through RiboGreen analysis and a UV / Vis spectrophotometer, respectively.

[0041] A composition for delivering genetic material according to one example can contain genetic material, particularly mRNA, with high encapsulation efficiency. Previously known compositions for delivering mRNA contained mRNA at a low rate, which limited their use as compositions for delivering mRNA. In contrast, lipid nanoparticles according to one example can contain mRNA with high encapsulation efficiency, specifically with an encapsulation efficiency of 85% or more.

[0042] In the present invention, the composition can be used to deliver genetic material into biological tissue or blood. The composition can be delivered through cells or intercellular junctions constituting the biological tissue, but there are no restrictions on the delivery method.

The above dosage is an example of an average case, and the dosage may be higher or lower depending on individual differences.

[0054] If the daily dosage of the above preparation is less than the above dosage, a significant effect cannot be obtained, and if it exceeds that, it is not only uneconomical but also outside the range of the usual dosage, so there is a risk of undesirable side effects, so it is better to keep it within the above range.

[0174] In addition, the composition for delivering genetic material according to the present invention exhibited a higher level of fluorescence expression compared to a control group using other mRNA carriers (PBS-treated group, mRNA-treated group, lipid nanoparticles (SM-102, MC3, DOTAP)).

[0175] The above results indicate that when the composition for genetic material delivery according to the present invention is used, there is a tendency for the efficiency of genetic material expression in vivo to increase.

[0176] Experimental Example 7. Confirmation of increased antitumor effect of cancer vaccine following increased tumor antigen mRNA expression after mixed administration of lipid nanoparticles and a hydrogen pump inhibitor to animal muscles.

[0177] To confirm the increase in antitumor effect of proton pump inhibitors (PPIs) as a result of increased expression efficiency of genetic material for tumor antigens at the biological level, the compositions of Examples 1-1, 2-1, and 3-1, prepared using tumor antigen mRNA (OVA mRNA), were administered to the muscles of mice a total of three times (each dose being 2 μg OVA mRNA), and subsequently, tumor cells (B16-OVA) expressing the corresponding tumor antigen were inoculated subcutaneously to compare the growth trends of the tumors.

[0178] As shown in Figure 9, a higher antitumor effect was observed when using the composition according to the present invention (lipid nanoparticles + PPI) compared to when lipid nanoparticles were administered alone.

[0179] These results indicate that when using the composition for genetic material delivery according to the present invention, the efficiency of genetic material expression can be increased through the activity of the hydrogen pump inhibitor.
