Description

[SPECIFICATION]
[Title of the Invention]
Pharmaceutical composition comprising large physiologically active substance and excipient
[Technical Field]
The present invention relates to a formulation for increasing the oral bioavailability of macromolecules. In particular, the present invention relates to a pharmaceutical composition comprising (i) a large physiologically active substance; and OH excipient A comprising a bile acid derivative; or (iii) excipient B comprising a compound or a derivative thereof having CYP450 inhibition, antioxidant effect, or gastrointestinal enzyme activity inhibition effect; and to a method of producing the same.
[Background Art]
In modern society relative to current eating habits, a large number of people are suffering from lifestyle diseases such as cardiovascular disease, diabetes, and osteoporosis due to changes in eating habits. Diabetes, a type of lifestyle disease, is spreading worldwide, and it is estimated that more than 1.5 million people die from diabetes every year. The global diabetes market is expected to grow from $80.15 billion in 2016 at a CAGR of 12.4%, reaching $161.69 billion in 2022. In addition, the market size is growing in all fields, including osteoporosis and cardiovascular diseases, due to aging resulting from medical advancements.
In terms of drug delivery methods, they are largely divided into oral and parenteral dosage forms; a large number of oral dosage forms of drugs are being developed considering cost, patient administration convenience, ease of production, and the like. From the perspective of treatment compliance of patients, the oral administration of therapeutic agents is generally considered to be a superior administration route than parenteral administration, and this is particularly true when the nature of the therapeutic agent or the nature of the condition to be treated requires multiple daily administrations of the therapeutic agent. However, despite this, macromolecules, such as polypeptides and polysaccharides, are known to be very difficult to successfully administer orally; accordingly, macromolecules have been administered parenterally, for example, by subcutaneous, intramuscular or intravenous injection. Therefore, it is highly desirable to provide a formulation that enhances the oral bioavailability of macromolecules to a range that allows oral administration of such macromolecules. In the case of diabetes treatments for which the market size is large and the growth potential is high, oral dosage forms have been developed by many companies. Specifically, the DPP-4 inhibitor series includes MSD's Januvia, Boehringer Ingelheim's Trajenta, LG Chem's Zemiglo, Novartis' Galvus, and AstraZeneca's Onglyza and Kombiglyze; the SGLT-2 inhibitor series includes AstraZeneca's Farxiga, Xigduo, and Boehringer Ingelheim's Jardiance, and the TZD series includes Takeda's Actos and Chong Kun Dang's Duvier. Additionally, there is Novo Nordisk's Rybelsus, which is an oral GLP-1. However, among the drugs above, DPP-4 inhibitors are sitagliptin, vildagliptin, saxagliptin, linagliptin, alogliptin and gemigliptin; SGLT-2 inhibitors are Dapagliflozin, Ipragliflozin and Empaglitlozin, and TZD is thiazolidinedione; and these are not macromolecular drugs The mass production of macromolecular drugs, such as insulin, heparin, calcitonin, interferon, and growth hormone, has become possible due to advances in electronic manipulation and biological processing, but macromolecular drugs have problems relative to their large molecular weight, making it difficult for them to pass through the gastrointestinal membrane or being easily broken down by digestive enzymes, and thus oral administration is limited, and treatment is consequently carried out by means of methods such as intravenous injection and intramuscular injection. These forms of administration, such as intravenous and intramuscular injections enter the systemic circulation directly and thus have the advantage of high bi oavai lability and rapid onset of drug effects, but the onset of drug effects due to immediate administration of drugs into the blood increases the risk of side effects. Furthermore, administration by injection is associated with low patient compliance due to pain and discomfort. There are also cases wherein self-administration is impossible or the administration must be performed in a hospital. In the latter case, when the half-life of the drug is short and repeated administration is required, such can also be a troublesome problem, and when hospital treatment or hospitalization is required, the increased burden on society can be problematic. To solve this problem, research is being conducted domestically and internationally to manufacture oral drugs, but there is a problem that macromolecular drugs generally have a bioavailability of only 0 to 2% when administered orally, making the possibility of success low.
Recently, many studies have been conducted on the oral absorption of macromolecular drugs, but the situation is such that the demand for oral drugs is increasing and that the supply thereof is insufficient. The present inventor aims to solve this problem by using a bile acid-based excipient.

<Embodiment 2: Confirmation of tight junction openness of bile acid derivatives and propyl gallate> <Experimental Example 1> Cytotoxicity of bile acid derivatives in Caco-2 cells Category Excipient Chenodeoxycholic acid or its salt (CDC) Deoxycholic acid or its salt (DC) Excipient A: Bile acid derivative Cholic acid or its salt (CA) Ursodeoxycholic acid or its salt (UDC) Glycholic acid or ts salt (GC) Taurochol c acid or its salt (TC) Gallic acid (GA) Propyl gallate (PG) Ethylenediaminetetraacetic acid (EDTA) Camostat mesylate (CM) Citric acid Soybean Kunitz tlypsin inhibitor (SBTO 2-0,4,5-trihydroxybenzoylloxyethyl 3,4,5-trihydrobenzoate The cytotoxicity of excipients was evaluated using Caco-2 cells using the following method. First, to check the amount of intracellular accumulation, Caco-2 cells were distributed in a 96-well plate at 1 x 105 per well and cultured in a CO2 incubator at a temperature of 37 °C. The culture solution from each well is removed and replacement by a new culture medium is performed. After that, 2.5 RE of the prepared excipient was added and this was cultured in a CO2 incubator at 37°C. After 2 hours, each well was treated with 100 iff of luciferase reagent (Promega, #G7571) and incubated at room temperature. After 10 minutes, the luminescence value of each well was measured. Cell viability (%) was calculated as follows, and the analysis results are as shown in FIG. 1. As shown in FIG. 1, the cytotoxicity of DC and CDC was similar, and UDC was confirmed to have the least cytotoxicity.
Cell viability (%) = (luminescence value/control luminescence value) x 100 <Experimental Example 2> Confirmation of tight junction openness of bile acid derivatives and propyl gallate in Caco-2 cells.
Using the monolayer membrane of Caco-2 cells, the tight junction openness and non-tight junction openness of the excipient was evaluated through the change in TEER value. First, to form a Caco-2 cell monolayer, 1.5 x 105-cells per well was dispensed in a 12-Transwell plate and cultured for 3 to 4 weeks under 37°C CO2 conditions. For the first week, the culture medium was changed once every two days, and thereafter, the culture medium was changed every three days. In the experiment, samples between 3 and 4 weeks after seeding were used. To evaluate the degree of damage to the Caco-2 cell monolayer by excipients, the degree of cells cultured as a monolayer on a semi-permeable membrane was measured by the difference in electrical resistance between the apical side and the basolateral side. First, the Transwell to be used in each test is washed using a washing buffer (HBSS), replaced by culture medium, and equilibrated in a 37°C CO2 incubator for 15 minutes. Mier adding 500 RE of the prepared excipient to the apical side and treating the basolateral side with 1.5 mL of culture medium containing no excipient, changes in TEER values were measured using a Millicell ERS-2 Voltohmmeter at each time point (0, 5, 15, 30, 45, 60, 90, 120 min) from the time of treatment. The TEER change (%) was calculated as follows, and the analysis results are as shown in FIG. 2.
TEER change (%) = (TEER value/control TEER value) >< 100 As shown in FIG. 2, according to the change in TEER value, the excipients having tight junction openness were CDC and DC, and the excipients having non-tight junction openness were UDC and PG. It was confirmed that even excipients having tight junction openness have reversible tight junction openness that returns to normal levels within 60 to 120 minutes after treatment.
<Embodiment 3> Measurement of Caco-2 cell membrane permeation pathway of bile acid derivatives Using the Caco-2 cell monolayer, changes in the permeability of markers for each permeation pathway due to excipients were evaluated using the following method. First, to form a Caco-2 cell monolayer, 1.5 x 10' cells per well were dispensed in a 12-Transwell plate and cultured for 3 to 4 weeks under 37°C CO2conditions. For the first week, the culture medium was changed once every two days, and thereafter, the culture medium was changed every three days. In the experiment, samples between 3 and 4 weeks after seeding were used. To verify the formation of a cell monolayer, JEER values and Lucifer yellow values were measured, and only cell monolayer membranes having a TEER value of 300 O*cm2 or more and a measured transmittance of Lucifer yellow within 3% were used in the test. After the Transwells to be used for each test were washed using transport media (HB SS) and incubated in a 37°C CO2 incubator for 1 hour, 500 [IL of bile acid derivatives and permeability marker were added to the apical side, and 1.5 mL of drug-free transport media was treated onto the basolateral side, and incubation was performed for 2 hours in a 37°C CO2 incubator thereafter. At this time, fluorescein isothiocyanate-dextran (FD4) was used as a paracellular marker, and metoprolol was used as a transcellular marker to confirm the change in permeability coefficient according to bile acid derivative treatment. After 2 hours, 1 mL each was sampled from the basolateral side, and the permeability coefficient (Papp value) of the drug was measured using enzyme-linked immunosorbent assay (ELISA) and liquid chromatography-mass spectrometry (HPLC).
