Description

The present invention relates to a pharmaceutical composition containing a lipid complex and a pharmaceutical composition containing lipid nanoparticles. More specifically, the present invention comprises a pharmaceutical composition comprising a lipid complex containing double-stranded ribonucleic acid (dsRNA) that suppresses the expression of complement C5 and double-stranded ribonucleic acid that suppresses the expression of complement C5. The present invention relates to a pharmaceutical composition containing lipid nanoparticles containing (dsRNA).

Proteins called complement include proteins represented by C1 to C9, and these proteins are activated in a chain by three different pathways (classical pathway, lectin pathway, and second pathway). An immune response is triggered. C5, the fifth component of complement, is degraded by C5 converting enzyme into C5a and C5b. The resulting C5a is called anaphylatoxin and provokes an inflammatory response in various cells via C5aR (CD88) and C5L2 (GPR77). The resulting C5b reacts sequentially with C6-C9 to form the final product, the complement membrane attack complex (MAC), which causes lysis and cell lysis of the pathogen. The complement system can have a strong damaging effect on host cells if it is not properly controlled or if it is over-activated.

From previous studies, complement C5 has been found in paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), severe myasthenia (MG), optic neuromyelitis (NMO), antibody-related kidneys. Transplant rejection, Gillan Valley syndrome, antiphospholipid cytoplasmic antibody-related vasculitis (ANCA-related vasculitis), muscle atrophic lateral sclerosis (ALS), Parkinson's disease (PD), autoimmune encephalitis, IgG4-related disease , Asthma, antiphospholipid antibody syndrome, ischemic-reperfusion injury, typical hemolytic uremic syndrome (tHUS), multifocal motor neuropathy (MMN), multiple sclerosis (MS), thrombotic thrombocytopenic purpura Disease (TTP), spontaneous abortion, habitual abortion, traumatic brain injury, cold agglutinosis, dermatitis, hemolytic uremic syndrome associated with Shiga toxin-producing E. coli, graft dysfunction, myocardium Infarction, sepsis, atherosclerosis, septic shock, spinal cord injury, psoriasis, autoimmune hemolytic anemia (AIHA), antiphospholipid syndrome (APS), myocarditis, immune complex vasculitis, Koan's disease, Kawasaki It is known to be involved in various diseases such as diseases (arteritis). Therefore, inhibition or suppression of complement C5 expression is expected to lead to the treatment of these diseases. In particular, paroxysmal nocturnal hemoglobinuria (Non-Patent Document 1), atypical hemolytic urotoxicity syndrome (Non-Patent Document 2), myasthenia gravis (Non-Patent Document 3), neuromyelitis optica (Non-Patent Document 4), For antibody-related renal transplant rejection (Non-Patent Document 5), it has been suggested that inhibition of complement C5 is useful for the treatment or prevention of these diseases.

Eculizumab (Soliris®), an anti-C5 monoclonal antibody, has high affinity for complement C5 and is complemented by inhibiting the cleavage of C5 to C5a / C5b and the concomitant complementation membrane attack complex formation. Suppresses excessive activation of the body. As a result, eculizumab has been shown to have an inhibitory effect on hemolysis, and is known as a therapeutic agent for paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome. Eculizumab is also known as a therapeutic agent for systemic myasthenia gravis (gMG). However, since eculizumab is very expensive, it is desired to develop alternative means that can be used for the treatment and prevention of complement C5-related diseases.

Examples of the method for suppressing the expression of complement C5 include a method using RNA interference (hereinafter, also referred to as “RNAi”). For example, a double-stranded ribonucleic acid (dsRNA) agent that results in cleavage of an RNA transcript of the C5 gene via RNA-induced silencing complex (RISC) is known (Patent Document 1).

<Method for producing lipid complex>
Examples of the method for encapsulating an effective molecule in the lipid complex include a reverse phase evaporation method, a Zwitterion (NaCl) hydration method, a cationic core hydration method, and a method using ethanol and calcium (Biomembr., 1468, 239). -252 (2000)) and the like. A lipid complex encapsulating double-stranded ribonucleic acid in the pharmaceutical composition according to one embodiment can be prepared by a method known in the art as described above.

In one embodiment, the lipid complex comprising double-stranded ribonucleic acid is a lipid solution comprising, for example, a cationic lipid and at least one lipid selected from the group consisting of neutral lipids, polyethylene glycol modified lipids, and sterols. And an acidic buffer containing double-stranded ribonucleic acid can be mixed. By such a method, a lipid complex whose inside is filled with a double-stranded ribonucleic acid and a lipid core is obtained. The lipid complex containing double-stranded ribonucleic acid according to one embodiment may contain a cationic lipid and at least one lipid selected from the group consisting of neutral lipids, polyethylene glycol-modified lipids and sterols. ..

The lipid complex containing the double-stranded ribonucleic acid according to one embodiment is at least one selected from the group consisting of (I) cationic lipids, (II) neutral lipids, polyethylene glycol-modified lipids and sterols, for example. The step (a) of mixing an aqueous solution containing a polar organic solvent containing a lipid and (III) an aqueous solution containing a double-stranded ribonucleic acid to obtain a mixed solution, and the content of the polar organic solvent in the mixed solution. It can be produced by a method comprising the step (b) of reducing.

A lipid complex in which double-stranded ribonucleic acid is encapsulated in fine particles composed of lipids by electrostatic interaction between water-soluble double-stranded ribonucleic acid and cationic lipid and hydrophobic interaction between lipids. Can be formed. For example, by reducing the content of the polar organic solvent in the mixture, at least one lipid selected from the group consisting of (I) cationic lipids and (II) neutral lipids, polyethylene glycol-modified lipids and sterols. A lipid complex can be formed by changing the solubility of a lipid component containing and in a polar organic solvent-containing aqueous solution. Examples of the polar organic solvent include alcohols such as ethanol.

First, in step (a), a polar organic solvent containing (I) cationic lipid and at least one lipid selected from the group consisting of (II) neutral lipid, polyethylene glycol-modified lipid and sterol is dissolved. The aqueous solution and the aqueous solution containing (III) double-stranded ribonucleic acid are mixed to obtain a mixed solution. The concentration of the polar organic solvent in the polar organic solvent-containing aqueous solution is not particularly limited as long as the conditions for dissolving the lipid molecule are satisfied even after mixing with the aqueous solution containing double-stranded ribonucleic acid. The concentration of the polar organic solvent in the mixed solution obtained in step (a) can be 0.1 to 60% by weight. (III) An aqueous solution containing double-stranded ribonucleic acid can be obtained, for example, by dissolving double-stranded ribonucleic acid in an acidic buffer.

Subsequently, in the step (b), the content of the polar organic solvent is reduced by adding water or the like to the above mixed solution. This allows the formation of lipid complexes. In order to efficiently form the lipid complex, it is preferable to sharply reduce the content of the polar organic solvent. As an example, the concentration of the polar organic solvent in the final polar organic solvent-containing aqueous solution in step (b) can be 0 to 5% by weight.

Alternatively, the mixed solution obtained in step (a) may be subjected to dialysis to remove the polar organic solvent and the solvent may be replaced with a pharmaceutically acceptable medium. Since the content of the polar organic solvent in the solution decreases during the dialysis process, this allows the formation of a lipid complex.

According to the method for producing the composition of the present embodiment, it is possible to efficiently obtain a lipid complex in which double-stranded ribonucleic acid is encapsulated inside fine particles.

Examples of the acidic buffer for dissolving the double-stranded ribonucleic acid include sulfuric acid buffer, phosphate buffer, phthalate buffer, tartaric acid buffer, citric acid buffer, formic acid buffer, oxalate buffer and acetate buffer.

The blood collected on each day of collection was placed in a tube containing a blood separating agent containing a coagulation promoter (IBL, Cat # 31203), centrifuged at 3000 rpm for 15 minutes, and the serum of the supernatant was collected and stored at -80 ° C. .. Then, the complement activity in serum was quantified by the following method. Specifically, serum complement activity CH50 kit (Denka Seiken Co., Cat # 400 017) was used to prepare sheep erythrocytes according to the manufacturer's protocol to a 1.5x10 ⁸ cells / mL. Subsequently, using the diluted solution attached to the serum complement titer CH50 kit, zymosan (Wako, Cat # 263-01491) was prepared to a concentration of 20 μg / mL. The sample serum was diluted 40-fold with a similar diluent. 50 μL each of the above sheep erythrocytes, zymosan, and diluted serum samples were mixed and incubated overnight at 37 ° C. The next day, the assay plate was centrifuged at 2000 rpm for 10 minutes at room temperature, and then the absorbance of the supernatant at 405 nm was measured. Table 23 shows the values of each sample when the complement activity contained in the serum on the day before administration of each individual was set to 100%. The complement activity of one mouse in the 1 mg / kg administration group was excluded because it was considered to be an abnormal value. Therefore, the values in the 1 mg / kg administration group in Table 23 are the average values of three individual mice. The PBS-administered group, 0.3 mg / kg-administered group and 3 mg / kg-administered group in Table 23 are the average values of four mice. The results are also shown in FIG.
