Abstract
Description
[Technical Field]
[0001] The present invention relates to a method for treating cartilage disorders, including anabolic and catabolic cytokine regulation. GLP-1 and GLP-1 analogs induce increased chondrocyte regeneration and decreased cartilage degeneration The present invention relates to a novel pharmaceutical composition comprising: [Background technology]
[0002] Osteoarthritis (OA) is the most common chronic joint disease. OA occurs in people over the age of 65. Affects nearly 50% of people, and in young people it occurs after a joint injury. 250 million people worldwide of people suffer from OA, and the disease has significant economic and social consequences for patients and healthcare systems. OA is characterized by structural degradation of the periarticular bone, synovial joint lining and adjacent supporting joints. Destruction of articular cartilage is a disease of the entire joint characterized by a tissue component. This results in an inability to maintain the balance between bone matrix synthesis and degradation. Interleukin-1β (I) produced by phages, monocytes, synovial cells, and chondrocytes Pro-inflammatory cytokines such as IL-1β play an important role in the pathogenesis of the disease.
[0003] Glucagon-like peptide-1 (GLP-1) is a post-translational product of the preproglucagon gene The action of GLP-1 on pancreatic β cells involves the upregulation of glucose transporter 2 expression. These include increased blood glucose levels, increased insulin secretion in response to increased glucose levels, and increased GL P-1 inhibits inflammation-inducing enzymes such as interleukin-6, tumor necrosis factor-α, and interferon-c. It has been shown to reduce the secretion of pro-inflammatory cytokines.
[0004] GLP-1 analogues are commercially available drugs prescribed to patients for the treatment of type 2 diabetes. Patent document 1 discloses some derivatives and analogs of glucagon-like peptide 1 (GLP-1). , their preparation, and their pharmaceutical use. Derivatives and Analogues of GLP-1 for Use in the Prevention and Treatment of Diabetes Mellitus - Patent application Regarding.
[0005] Initially, osteoarthritis was thought to be a disease of the articular cartilage, but recent studies have shown that Symptoms of rheumatoid arthritis have been shown to affect the entire joint.
[0006] Although articular cartilage loss has been considered a primary change, cellular and biomechanical changes have been implicated. The combination of stress and stress can cause subchondral bone remodeling, osteophyte formation, bone marrow lesion development, synovial membrane involvement, and osteoporosis. Several conditions, including changes to the joint capsule, ligaments, and periarticular muscles, as well as meniscal tears and extrusions, can occur. This causes some secondary changes.
[0007] There are two patterns of cartilage growth. One is interstitial growth, which is differentiated into chondrocytes. The cells surrounded by the cartilage matrix proliferate by cell division. Another growth pattern is the expansion of the cartilage tissue by the perichondrium. Cartilage tissue is covered with perichondrium except for the articular surface of the articular cartilage. The perichondrium is composed of fibroblasts, which are similar to the chondrocytes in the inner layer. The difference between fibroblasts and chondrocytes is unclear. The cells of the inner layer of the perichondrium gradually change into a round shape. These cells then grow outward, secreting further cartilage matrix.
[0008] Patent Document 2 discloses an incretin hormone or its derivatives for use in the treatment of osteoarthritis. More specifically, this patent relates to analogs of benzodiazepines for use in the treatment of osteoarthritis. The patent discloses the use of GLP-1 and GLP-1 analogs such as liraglutide. The peptides disclosed in the patent of Reference 2 are administered by systemic (parenteral, intravenous, etc.), oral, rectal The drug may be administered via any known route of administration, including intravenously, topically, or subcutaneously. It does not disclose the role of GLP-1 in bone degradation, nor has it demonstrated an association with chondrocytes. do not have.
[0009] Normal turnover of cartilage matrix is mediated by chondrocytes, which Chondrocytes synthesize proteins and the proteolytic enzymes involved in their breakdown. Growth factors and cytokines, structural and physical stimuli, as well as matrix metalloproteinases, It is influenced by many factors, including body composition.
[0010] Osteoarthritis is a condition in which chondrocytes are unable to balance between anabolism and catabolism of these extracellular matrix components. This is due to the inability to maintain normal function, which initiates an imbalance between cartilage breakdown and repair. The mechanism of action of the enzyme is not well known. The resulting inflammation can allow for the formation of wear particles, which are then transported by resident macrophages. At some point, the production of these wear particles exceeds the system's ability to eliminate them. They act as mediators of inflammation and stimulate chondrocytes to release degradative enzymes. Degradation of collagen and proteoglycans also taken up by synovial macrophages These molecules induce the release of pro-inflammatory cytokines such as TNFα, IL-1, and IL-6. There is a close relationship between cytokine expression and OA. Interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) stimulate synovial cells and carcinomas. Interleukin-6 (IL-6) and interleukin-8 (IL-8) production by bone cells However, all studies have focused on synovial tissue rather than chondrocytes. was.
[0011] Anabolic stimulation of chondrocytes occurs via stimulation of proteoglycan and collagen synthesis. Measured in vitro.

[0167] The basal inflammatory profile of each patient was calculated using the calculated concentrations of each detected cytokine. The evaluation was carried out by accumulating the means.
[0168] The results showed that the basal inflammatory profile was consistent with high levels of inflammatory cytokines in two patients and The results were highly variable, including two patients with high and low cytokine levels. .
[0169] Each patient's Victoza® response inflammation profile was determined The results were evaluated by comparing the ratio of the calculated mean concentrations of each cytokine before and after treatment with TM. The general results show that each patient responds differently. Equivalent responses to IL-1β were observed in mice treated with Victoza® in relation to IL-1β. Four cytokines were detected in three of the four patients' chondrocytes; The calculated mean concentrations of MCSF and CXCL10 / IP-10 (anabolic cytokines) increased. However, IL7 and MCP1 (catabolic cytokines) were decreased (Figure 1).
[0170] conclusion We demonstrated different response profiles in each of the four patients tested. Liraglutide inhibits some anabolic cytokine secretion in chondrocytes from OA patients. Increases vasopressin levels and reduces catabolic cytokine secretion to some extent.

[0179] Liraglutide formulation for stability testing: For stability testing, 1.02 ml of PBS 1 mg of liraglutide in the capsule was mixed with 10 ml of artificial synovial fluid.
[0180] Test Procedure Determination of release profile: For each formulation prepared, the release profile was determined. On day 0, 10 ml of liraglutide hydrogel formulation (1 mg / ml - 1.02 ml) was administered. The released molecules were placed in a semipermeable membrane test system immersed in artificial synovial fluid at 37°C. This membrane should allow free diffusion of liraglutide monomers into the artificial synovial fluid. However, the physical barriers of liraglutide oligomers and hydrogel formulations are Synovial fluid samples (0.2 ml each) were collected after 1, 2, 4, 7, 10 and 14 days. The collected sample was replaced with fresh artificial synovial fluid to maintain the same volume of fluid outside the membrane. A sample of the fluid was taken from the test tube for further ELISA analysis to determine the liraglutide concentration. It was stored at 2-8°C until completion.
[0181] Stability Testing: To determine the stability of liraglutide under test conditions, Solutions of liraglutide in artificial synovial fluid were prepared at appropriate concentrations and administered in the same manner as the liraglutide hydrogel formulation. Processed.
[0182] ELISA procedure: Quantification of liraglutide concentration was performed with an ELISA kit. The procedure was performed according to the kit supplier's recommendations with one exception: the calibration curve used The standards had higher concentrations than suggested, ranging from 0.977 to 1000 ng / ml. The samples were diluted in EIA buffer. Standards and controls were prepared from a single stock solution of liraglutide. The assay was carried out on several EIA plates. All plates contained the same standard The expected concentration of liraglutide in the diluted samples was 5-22%. Expected concentration ranges for samples: 15, 100, and 200 ng / ml. Three quality controls were used at concentrations covering 100 ml. Each point was measured twice. Measured at 450 nM with a 96-well plate reader.
[0183] Experimental design and conditions Length of the experimental period: The day of formulation preparation and membrane loading was considered as "day 0", and the end of the experiment was considered as "day 1". It was considered the fourth day.

[0189] Liraglutide was analyzed accurately and reliable results were obtained. The data are shown in Appendix II. All plates passed two of the three quality controls. The standard was met, i.e., the concentration was within ±20% of the theoretical concentration. Guidelines on bioanalytical method validation tion(EMEA / CHMP / EWP / 192217 / 2009Rev.1Corr. 2 ** ) was accepted.
[0190] Liraglutide concentration: Samples from artificial synovial fluid were diluted to 1:400 before proceeding with ELISA staining. All samples collected from the first five time points were analyzed. These eight samples were also analyzed based on the expected consistency of the formulation at the start of the study.
[0191] Determination of release profiles: Maximum expected liraglutide concentrations for all hydrogel formulations The results were calculated as a percentage of the observed values. The amount of liraglutide was not included in the calculation. When glutide is released from the semipermeable membrane, the concentration is 90.74 μg / ml (corresponding to 100%). )
[0192] The calculated percentages for the six best formulations are shown below (Table 5).

[0196] The purpose of this study was to investigate the effects of three surgically induced models of osteoarthritis in rats. The objective of this study was to evaluate the efficacy of a liraglutide-based formulation of
[0197] material and method
[0198] Test substance: liraglutide Vehicle: PBS Liraglutide Formulations: Three viscous hydrogel formulations were tested: Formulation 6: High release Formulation 8: Medium release Formulation 20: Low release
[0199] Unformulated liraglutide corresponds to liraglutide dissolved in PBS.
[0200] The formulations were prepared on the day of treatment for each of the three cycles. For each formulation, 4 mg of liraglutide in 2 ml of the compounded solution or PBS (for uncompounded liraglutide) This resulted in a dose level of 0.18 mg / kg in 25 μl for intra-articular injection. Assuming 0g, the dose administered to each rat was 50µg. It was used to dose the animals within one hour of preparation.
[0201] Experimental model Animal species / strain: Rat / Sprague Dawley (SD) Gender / number / weight average: male / 60 / 6-8 weeks old at the start of the test Diet: Animals were fed commercial rodent chow ad libitum.
[0202] Experimental design and conditions Rats were assigned to one of five stratified study groups according to body weight.
[0203] OA induction by medial ligament transection (MLT) procedure followed by resection of the medial meniscus (MMx) Each rat was anesthetized by the chamber induction technique using inhalation anesthesia (isoflurane 4.0%). During surgery, animals were maintained with isoflurane at a level of 1.5–2.5% and oxygen The flow rate was 1-2 liters / min. Ophthalmic ointment was applied to the eyes to prevent drying of the tissue during the anesthesia period. After induction of anesthesia, the hair on the surface of the skin of the right leg was removed using an electric animal clipper. After shaving the knee joint, the skin was disinfected with iodine and a parapatellar skin incision was made on the medial side of the joint. The medial side of the ganglion cavity was incised. The medial ligament was cut and the medial meniscus was excised using a microsurgical knife. The wound was closed with vicryl 5 / 0 braided absorbable sutures. All surgical procedures were performed under a surgical microscope. Group assignments are shown in Table 6, and the study timeline is shown in Table 7.

[0205] [Table 7]
[0206] Testing and Evaluation The weight-bearing changes of OA rats were measured using an incapacity tester. Postural imbalance is reduced, with each hind leg reported to be incapacitated. Each rat was placed on a separate force plate on the apparatus, with each hind paw supported. The weight was measured for 5 seconds. The ratio of the load weight of the right hind paw to the left hind paw was calculated. The average value of consecutive measurements was recorded. Weight-bearing function (incapacity test) was measured at baseline ( The experiment was conducted four times in total on days 1, 14, 28, and 35. I didn't have the knowledge.
[0207] On day 36, rats were sacrificed by CO2 asphyxiation. Knee joint structures were examined for further histological analysis. The contralateral (uninjured) knee was also fixed in 4% buffered formalin. The tissue was fixed in a solution of acetone.
[0208] Numerical results were given as mean ± SD after Grubbs' test analysis at α = 5%. Outlier data points (marked with an asterisk) were identified and not included in the group mean calculation. Where applicable, statistical analysis was performed using two-way ANOVA followed by Bonferroni post hoc tests. ) or one-way ANOVA (followed by Dunnett's multiple comparison post-hoc test). A probability of 0.05% (p≦0.05) was considered significant. In the figure, the degree of statistical significance between groups is indicated by * p ≤ 0.05, ** p<0.01 and *** Shown as p<0.001.
[0209] result Weight Load Test Weight bearing changes in rats with OA were assessed by measuring the weight the animals distribute to each hind paw independently. All animals were evaluated using a disability meter. Before OA induction, the weights of both hind paws were equalized. On day 14, there was a significant increase in the weight loading difference (R / L weight percentage) compared with the control group. This was observed between group 3M and group 3M, accompanied by a prolonged release of liraglutide (Figure 3).
[0210] Histological evaluation Slides were examined by a single pathologist blinded to the treatment groups. The cross-section of the knee was evaluated for the data. Cartilage matrix loss width (0% cartilage intact, 100% is the highest point reached, 50% is the intermediate region) ) Cartilage degeneration score (score 0-5, see section 9.1). Total cartilage degeneration width (0% cartilage intact, 100% is the highest point, 50% is the intermediate region). includes all possible degenerative changes. Significant cartilage degeneration width. Measurements of more than 50% of the thickness are significantly impaired (+ / -). Lesion zonal depth ratio (microns). Osteophytes (score 0–4, see section 9.2). Calcified cartilage and subchondral bone damage score (score 0-5, see section 9.3) stomach). Synovial reaction (score 0-4, see section 9.4).

[0211] The percent cartilage matrix loss was 43.6% compared to the vehicle-treated control group (1M). The lowest was Group 3M (35.8%). Total cartilage degeneration width (%): This was also the same as in the vehicle-treated group. The incidence was lowest in Group 3M (37.5%) compared to Group 1M (43.2%) in the control group. A Bonferroni post-hoc comparison followed by a one-way ANOVA revealed that the control group A statistically significant difference in cartilage degeneration between the 3M and liraglutide-treated animals was revealed. It became ( * P<0.05). Mean + / -SD, n=11~12.
[0212] conclusion The purpose of the study was to evaluate the efficacy of three liraglutide-containing steroids in the treatment of osteoarthritis in rats using a surgically induced model of osteoarthritis. The objective of this study was to evaluate the effectiveness of the ointment-based formulation.
[0213] The results of this study showed that liraglutide in formulation 6 (group 3) corresponds to a high release of liraglutide. M) showed a significant improvement in the incapacity meter compared to vehicle-treated control animals 14 days after OA induction. The results showed that the weight-bearing test induced a statistically significant reduction in OA damage. The Von Frey test did not reveal any statistically significant differences between all animal groups. Cartilage degeneration was also significantly reduced in the relaxants treated with formulation 6 compared to the control and other formulations. Weight-bearing tests and histological evaluation clearly demonstrated that the OA rat model were susceptible to testing new therapeutic treatments in the
[0214] Liraglutide formulated in formulation 6 exhibited a significant improvement in efficacy compared with other formulations or unformulated liraglutide. and has chondroprotective effects in vivo.
[0215] Example 4: Albumin-dependent effects of liraglutide using a surgically induced model of osteoarthritis in rats Dose-response study using a methicone-based formulation
[0216] The principle of the test is to evaluate the efficacy of albumin as a therapeutic agent for measuring disease parameters in a rat OA model. The evaluation was based on the combined use of liraglutide.
[0217] material and method
[0218] The test substance was liraglutide, and the positive control was dexamethasone (and Novo No Unformulated liraglutide Victoza® (6 mg / ml injection) manufactured by Rdisk )) is.
[0219] compound The vehicle (formulation excipient) was phosphate-buffered saline for intra-articular injection into groups 1M and 7M. It consisted of albumin resuspended in saline (25 μl).
[0220] Albumin-based formulations of liraglutide (high, medium, and low doses) were administered as follows: Prepared to:
[0221] Liraglutide (supplied as a powder) was dissolved in an appropriate volume of vehicle for intra-articular injection. 0.18 mg / kg (groups 2M and 8M), 0.06 mg / kg (group 3M) in 25 μl or 0.02 mg / kg (Group 4M). The formulation was administered in each of three cycles. were prepared on the day of treatment.
[0222] The positive control used in Group 5M was dexamethasone. The human clinical dose for knee treatment was 4 mg / injection, which is equivalent to 0.4 mg / kg in rats. It was supplied "ready to use" at a concentration of 4 mg / ml. The volume was 25-50 μl depending on the rat's average BW on each treatment day.
[0223] Unformulated liraglutide (Victoza®) is available as a 6 mg / ml stock solution. The human clinical "starting" dose for diabetic patients was 0.6 mg / day (as repeated SC injections). (supplied), which is equivalent to 0.06 mg / kg in rats. A stock solution of Benzyl Alcohol (R) was prepared at a final concentration of 0.006 mg / ml for SC injection in Group 6M. The solution was diluted 1000-fold with physiological saline for injection to achieve a concentration of 10 ml / kg.
[0224] Experimental model Animal: Rat / Strain: SD Gender: Male / Number: 72 / Age: 6-8 weeks old at the start of the test Supplier: Janvier Labs, France Initial body weight: The average body weight at the start of the study (day 1) was 260 g. Minor and maximum weights were within ±20% of the group mean. Diet: Animals were fed commercial rodent chow (Safe ref#A04) ad libitum. Animals had free access to filtered drinking osmotic water. Contaminants: Contaminants in food and water supplies that may affect the results of this test It wasn't there.
[0225] Experimental design and conditions Definition of study start and end: The day of OA induction was defined as "Day 1." The end of the study was set at "Day 36." In the satellite group study, the end of the study was set at "Day 57." It was decided.
[0226] Allocation to treatment groups: Rats were randomly assigned to one of eight groups according to body weight. Ta.
[0227] Study design and timeline: The study was conducted as follows: This was carried out in three cycles according to Table 2.
[0228] OA induction by medial ligament transection (MLT) procedure followed by resection of the medial meniscus Anesthesia was induced by the chamber induction technique using inhalation anesthesia (isoflurane 5.0%). During surgery, the animals were kept under isoflurane at a level of 1.5-3.5% and airflow at 1-30°C. The flow rate was 2 liters / min. Ophthalmic ointment was applied to the eyes to prevent drying of the tissue during the anesthesia period. After induction of anesthesia, the hair on the surface of the skin of the right leg was removed using an electric animal clipper. After hair removal, the skin was disinfected with iodine and a parapatellar skin incision was made medial to the joint. This incision provides access to the exposed joint. The medial ligament is cut and a microsurgical knife is inserted. The medial meniscus was excised using a surgical knife. The wound was closed with vicryl 5-0 sutures. Surgical procedure All procedures were performed using a surgical microscope. Group assignments are shown in Table 8, and the study timeline is shown in Table 9. Shown below.
[0229] [Table 8]
[0230] [Table 9]
[0231] Testing and Evaluation Joint swelling: Measurements of knee diameters were taken and joint swelling was inferred as an index of inflammation. Measurements were performed using a digital caliper while the rats were anesthetized. The experiment was conducted on the day after surgery (for baseline), and then once a week until the end of the study. I had no knowledge about it.
[0232] Weight-bearing test: The weight-bearing changes of rats after OA induction were monitored using an incapacity test system. Postural imbalance, which has been reported to show changes in pain threshold and weight distribution in the extremities, was observed. Each rat was tracked so that each hind paw was placed on a separate force plate on the incapacitation device. The weight supported by each hind paw was measured for 5 seconds. The ratio was calculated. The average of three consecutive measurements for each rat was recorded. Function (incapacity test) was assessed at baseline (day 1), days 14, 28, and 35. A total of four trials were performed on each eye. The experimenter was blinded to the groups.
[0233] Animal sacrifice and tissue fixation: On day 36 (the end day of groups 1M-6M), all animals were bled. The rats were euthanized with a lethal dose of Euthasol vet. Knee joint structure The contralateral side was harvested and fixed in 4% buffered formalin solution for further histological analysis. The (uninjured) knees were also fixed in 4% buffered formalin solution. On day 57 (satellite groups 7M-8), On the final day of the study (the end of the study period), rats were euthanized. Knee joint structures were collected for further histological analysis. The contralateral (uninjured) knee was also fixed in 4% buffered formalin. The tissue was fixed in a solution of acetone.
[0234] Histological analysis: Histological analysis was performed. Knee joint sections were stained with hematoxylin-eosin or The extent of pathological lesions was assessed by staining with toluidine blue. erwin et al., Osteoarthritis and Cartilage18(20 10) Scored as S24-S34.
[0235] Histological analysis was performed on: Right knee (affected): All groups, 10 animals / group, collected on day 36. Sample size: n=60 Left knee (healthy control): Vehicle group 1M, 5 animals / group. Sample size: n=5 Right knee (affected): All animals in groups 7M-8M, 6 animals / group, collected on day 57. Sample size: n =12 Total sample size: n=77 Statistical analysis: Numerical results were presented as mean ± standard deviation (SD). Outliers or excluded data were excluded. Data points (marked with $) were not included in the group mean calculation. or one-way ANOVA (followed by Dunnett's multiple comparison post-hoc test) to evaluate statistical significance. A statistical analysis was performed. A probability of 5% (p≦0.05) was considered significant. In the figures, the results are shown as mean ± S The degree of statistical significance between groups is shown as EM. * p ≤ 0.05, ** p<0.01 and *** Shown as p<0.001.
[0236] result In this study, six groups (1M-6M, n = 9-10 per group) were assigned from day 1 to day 36. I tracked it.
[0237] Histological analysis revealed no lesions in the right knee joint, so the animals from Group 2M were Subject 2 was excluded from the entire study.
[0238] Knee Measurements (KM): Knee measurements were recorded preoperatively, the day after surgery, and weekly thereafter. For each group, the mean diameters of the left and right knees in two dimensions were calculated.
[0239] At termination, rats from group 2M treated IA with high doses of liraglutide (width and thickness ), in rats from group 3M treated IA with medium dose liraglutide (thickness), A response is observed. As shown in Figure 5, the group treated SC with Victoza® Rats from 6M (thickness) also showed a significant decrease in knee measurements compared to the vehicle-treated group 1M. A little.
[0240] Weight bearing test: Changes in weight bearing in rats with OA were assessed by measuring the weight the animals distributed to each hind paw. The incapacity test was performed on Day 1 (baseline) ) and on days 14, 28, and 35. On day 14, Victoza® A significant increase in the R / L ratio in % was observed for group 6M treated with . Although not significant, it was also observed during the other measurement periods (days 28 and 35). Control animals and those receiving either a medium dose (14 and 35 days after OA induction) or a high dose (35 days) were treated with OA. A small, non-significant trend for weight bearing differences was observed between liraglutide IA-treated animals and those treated with liraglutide IA. was done.
[0241] Histological analysis The left hind limb (from animals 1M1, 1M9, 1M26, 1M31, and 1M57) served as a control. As expected, the knee joint showed no lesions.
[0242] In all groups, the lesions observed ranged from marked to severe. The observed pattern is a localized widespread tear of the cartilage, generally involving the entire medial tibial plate. It was.
[0243] The ulcerative margins are generally characterized by fibrillation of the cartilage and / or complete destruction of the proteoglycan matrix. The subchondral bone was generally characterized by necrosis with complete loss of bone. The osteochondral interface (highest attained) including the area beyond the friction zone was confounded with fibrotic bundles (fibrosis). At this point, the subchondral bone showed necrosis (eosinophilia with surrounding fibrin, karyorrhexis, cells showing pyknotic nuclei).
[0244] The dexamethasone IA treatment group (5M group) and the Victoza® SC treatment group ( 6M group) tended to show lower cartilage loss. However, in some individuals, fibrous tissue forming adhesions between the medial meniscus remnant, femoral cartilage, and synovium, as shown in Near complete replacement of the tibial plate was observed.
[0245] The observed repair changes were characterized by fibrous collagen bundles within the synovial capsule, which were associated with dextromethorphan. Metasone IA treatment group (5M) and Victoza® SC treatment group (6M) shows large fibrous papillary-like highly vascularized processes, and other structures (inner Adhesions may form in all joints (meniscal remnants, articular cartilage, ligamentous remnants) In the liraglutide IA treatment group, no fibrosis was observed and no pathological differences were observed. In the glutide IA-treated group, chondrocyte nests were observed in the cartilage with a dose-response pattern (Figure 7): 3 / 9 in the high dose group, 2 / 8 in the medium dose group, and 1 / 9 in the low dose group In the Victoza® SC treatment group, only 1 out of 7 animals had chondrocyte nests. showed proliferation in the 10 mice but not in the vehicle-treated group (0 / 10 mice).
[0246] These observed chondrocyte proliferations suggest attempts at cartilage regeneration.
[0247] Satellite group study In the satellite group study, two groups (7M-8M, group equivalent) were used from day 1 to day 57. The histological parameters were measured as previously in this study. The percentage of recovery 3 weeks after treatment cessation was assessed in the liraglutide high-dose IA treatment group. and vehicle groups were compared and analyzed.
[0248] [Table 10]
[0249] Overall, the lesions observed were significant for both groups. Thus, the typically observed pattern is a localized dislocation of the cartilage involving most of the medial tibial plate. The ulceration margin was covered with cartilage fibrillation and / or proteoglycans. It was characterized by necrosis with complete loss of matrix.
[0250] Animals treated IA with high doses of liraglutide (Group 8M) were significantly higher than vehicle-treated animals (Group 7M) ) and lower matrix loss in the liraglutide IA-treated group compared with placebo. There is a tendency for losses to decrease over time (Figure 8).
[0251] No differences were observed in degeneration scores and total degeneration width. Throughout the course of the study, degeneration scores were significantly higher in the liraglutide IA-treated group at Z1 and Z3. was lower (Fig. 9).
[0252] There was no significant difference in osteophyte formation between the two groups. However, the course of the study after treatment cessation Overall, the percentage of osteophytes tended to be lower in the liraglutide IA-treated group.
[0253] The high-dose treatment group showed more significant synovial repair as observed by membrane thickening compared to the control group. (Figures 10 and 11).
[0254] An example of a nest diagram is shown in Figure 12. As assessed in Figure 13, the vehicle group (2 / 5; 8 0.1±4.1 foci / μm 2 ), compared with the high-dose test substance treatment group (5 / 6; 30 0.6±7.0 foci / μm 2 ) significantly more chondrocyte nests were observed within the chondrocytes.
[0255] conclusion As previously observed during this study, significant differences in each group regarding cartilage, subchondral bone, and synovial membrane were observed. Histological changes were observed.
[0256] Synovial repair changes were significantly greater in the IA treatment group with high-dose liraglutide compared to the vehicle group. Furthermore, cartilage degenerative changes were more pronounced in the liraglutide-treated group compared to the vehicle group. Although the difference was not significant, it was not statistically significant.
[0257] In particular, more chondrocyte nests were observed in the liraglutide IA treatment group, indicating intracartilage regeneration. Attempts have been proven.
[0258] Under the test conditions, dexamethasone IA and Victoza® SC treatment significantly reduced several OA-related defects (knee joint swelling, incapacity, tissue loss associated with cartilage loss) Although the IA treatment group was able to reduce the fibrosis (i.e., the fibrosis was not observed in the IA treatment group), repair was not observed in the IA treatment group. accompanied.
[0259] Interestingly, histological analysis showed that the endochondral chondrocytes were significantly smaller in the liraglutide-treated group than in the control group. showed alveoli.
[0260] These figures show chondrocyte proliferation demonstrating attempts at cartilage repair. In the IA liraglutide-treated group, the presence of foci was not associated with changes in synovial repair. However, in the satellite study (day 57), IA treatment with high doses of liraglutide The chondrocyte nests seen in the animal group were associated with more pronounced synovial repair changes (thickening).
[0261] Overall study results suggest that liraglutide may play a role in the inflammatory and regenerative processes associated with OA. This indicates that the targeting mechanism is related to the
[0262] Example 5: Reactivation of chondrogenesis in an in vitro differentiation model of human mesenchymal stem cells The effects of Chido
[0263] The present inventors have demonstrated that cartilage formation occurs in an in vitro differentiation model of human mesenchymal stem cells (hMSCs). To test the effect of liraglutide on chondrogenesis and determine whether liraglutide promotes chondrogenesis. was evaluated.
[0264] material and method Test material: Liraglutide. Test system: Human mesenchymal stem cells (StemPro BM, Cat A15652, The rmoFisher Scientific). Basal medium: MesenPRO RS growth supplement, L-glutamine (1%) and Genta MesenP supplemented with 100 ml of medium containing 10 mg / ml of cephalosporin (50 μl per 100 ml of medium). RO RS basal medium (ThermoFisher Scientific). Differentiation medium (used as positive control): StemPRO chondrogenic differentiation supplement and Gentamax StemPR supplemented with isin (10 mg / ml, 50 μl per 100 ml of medium) O Chondrogenic Differentiation Medium (ThermoFisher Scientific)
[0265] procedure Mesenchymal stem cells were used at a confluence of 60-80%. and 1.6 × 107 cells were cultured in basal medium (MesenPRO RS basal medium + supplements). A cell suspension of 100 cells / ml was prepared.
[0266] 5 μl of this suspension was placed in the center of a well of a 24-well plate. The plate was incubated at 37°C for 1 hour. The plates were incubated in a humidified incubator for 2 hours. After 2 hours, the plates were incubated in a humidified incubator for 2 hours. 11. For the test timeline, follow Table 12 and add either (negative control) or 1 ml of basal medium containing the test substance was added. As a positive control, differentiation medium (StemPR 1 ml of chondrocyte differentiation basal medium + supplements was used. The plate was incubated at 37°C in 5% CO2. The cells were returned to the incubator for 7, 14, or 21 days. During the differentiation phase, the medium was changed every 3–4 days. I replaced it.
[0267] [Table 11]
[0268] [Table 12]
[0269] At the end of each test period (8, 15, or 22 minutes), alcian blue staining and microscopic analysis were performed. The plates were harvested for analysis. The medium was removed and 1 ml of PBS was added to gently incubate the cells. The PBS was removed and 1 ml of 4% formaldehyde was added for 30 minutes at room temperature. .
[0270] Then, remove the 4% formaldehyde and gently rinse the fixed cells twice with 1 ml of distilled water. The distilled water was removed and 1 ml of 1% Alcian blue (prepared in 0.1 N HCl) was added. The staining solution was removed and the cells were soaked in 1 ml of 0.1% PBS (prepared by manufacturer) for 2 hours at room temperature and protected from light. The plate was washed twice or three times with N HCl. The HCl solution was removed, and 1 ml of distilled water was added to each well. The cells were observed under a microscope and photographed.
[0271] result The effect of liraglutide on sphere formation was assessed by microscopic observation 5 days per week. Then, Alcian blue staining was performed at three time points (e.g., 7, 14, and 21 days after treatment). This dye uptake reflects the presence of sulfated glycosaminoglycans (GAGs), Demonstrates the formation of chondrocyte spheroids.
[0272] [Table 13]
[0273] As shown in Table 13, sphere formation was observed for vehicle-treated cells in basal medium throughout the study. No spherogenesis was observed with a dose-response for the two test doses of liraglutide. Indeed, in cells treated with 10 nM and 100 nM liraglutide, On day 22, sphere formation was observed in 67% and 100% of treated wells, respectively. The enriched medium induces hMSCs to commit to the chondrogenic pathway and generate chondrocytes. As expected, the spheres were not spheroidized for vehicle-treated cells in this medium. Formation was observed (83% of treated wells on day 22). The liraglutide-induced spheroids were confirmed to be chondrocyte spheroids. This indicates that chondrocyte differentiation can be induced by spheroid formation and positive adenosine monophosphate (SA) alone. An example of Lucian blue staining is shown in FIG.
[0274] conclusion In this study, an in vitro assay for chondrogenesis was used to assess the role of chondrogenesis in this process. The effect of raglutide was tested.
[0275] We found that liraglutide induced sphere formation in a dose-response manner in the presence of basal medium. The results demonstrated that chondrocyte sphere formation was observed in the vehicle-treated cells. This was confirmed by positive Lucian blue staining (a marker of cartilage matrix synthesis).
[0276] Under the conditions tested, our data demonstrate that liraglutide alone commits hMSCs to the chondrogenic pathway. This indicates that liraglutide induces the production of chondrocytes. The ability to target resident stem cell populations in the joint area and stimulate cartilage repair through chondrocyte differentiation This allows stimulation of the OA, which is considered a promising approach for the treatment of OA.
[0277] Example 6: Effect of liraglutide on mouse primary chondrocyte viability
[0278] The purpose of this study was to investigate the effect of liraglutide on cell viability using mouse primary chondrocytes. The purpose was to evaluate the effectiveness.
[0279] material and method Test material: liraglutide Test system: Mouse primary chondrocytes Cell culture media formulation DMEM containing 2 mM L-glutamine, 10% fetal bovine serum (FBS), 1% penicillin Phosphorus / streptomycin was used for cell culture from day 1 to day 7. On day 7, 2 m DMEM containing M L-glutamine, 0.1% bovine serum albumin (BSA), and 1% Penicillin / streptomycin (P / S) was used in the absence of FBS. .
[0280] Experimental design and conditions Definition of test start The day the cells were plated into the wells was considered "Day 1," and the end of the test was considered "Day 9." Everyone agreed.
[0281] procedure Isolation of mouse articular cartilage Immature mouse chondrocytes were derived from newborn mice (5-6 day old C57Bl / 6). All procedures were carried out in a sterile flow hood. The mice were then decapitated with scissors to ensure their safety. After death, the animals were fixed in a prone position and the front legs were pinned with needles. The hind legs were then cut with scissors and pliers. The skin was removed from the hind limbs along the spine. The skin and muscle residues were removed from the limbs. The foot is flattened with curved forceps to release the small, translucent, hard sphere that corresponds to the femoral head. When the ball was separated, it was placed in 30 ml of 1x PBS and the muscle was removed from the rest of the leg. The bones were then removed from the bones and other tissues. The bones appeared reddish-brown and the cartilage appeared white. The cut is made on both sides, which is the joint (forming two balls). After removing the tissue, the sphere was cut in half to separate the two spheres, and then cut in half again. This allows for easier digestion. The femoral condyles and tibial plateaus were also placed in 30 ml of 1x PBS. I put it in.
[0282] Isolation of immature mouse chondrocytes The cartilage pieces were placed in a 100 mm Petri dish with 10 ml of digestion solution (DMEM, 2 mM L-Glutamine). Incubate at 37°C in 5% CO2 in a medium containing glutamic acid, 1% P / S, and 3 mg / ml collagenase. Between the two digestions, the cartilage pieces were incubated in beta for 45 minutes. After two digestions, the contents were collected using a 25 ml pipette and placed in a new Petri dish. The cartilage fragments were placed in 10 ml of DMEM, 2 mM L-glucose, and in a solution of tamoxifen + 1% P / S and 0.5 mg / ml (diluted 1 / 6) collagenase D The cells were incubated overnight in an incubator at 37°C and 5% CO2.
[0283] Chondrocyte seeding After overnight digestion, 10 ml of DMEM, 2 mM L-glutamine + 10% FBS was added to each petri dish. The collagenase D was added to the dish to stop the action of collagenase D. The medium and residual cartilage were collected and Place in a 0 ml Falcon tube. Disperse the aggregates using a reduced size pipette. This was carried out to obtain a suspension of separated cells, which was then filtered through a sterile 70 μm cell strainer. The cells were centrifuged at 400 g for 10 minutes at 20°C. The medium was removed and the pellet was collected in 5 ml of The cells were washed by resuspending in PBS. The cells were centrifuged at 400 g for 10 minutes at 20°C. Remove the PBS and add 15 ml of DMEM 2 mM L-glutamine + 10% FBS + 1% P / S. The chondrocytes were counted using a Neubauer hemocytometer, and the viability of the extracted cells was determined. The chondrocytes were cultured in 2 ml of DMEM 2 mM in a 12-well plate. 40 x 10 in L-glutamine + 10% FBS + 1% P / S / well 3 Cells seeded at a density The cultures were maintained under inorganic conditions in an incubator at 37°C and 5% CO2.
[0284] Chondrocyte culture Immature mouse articular chondrocytes reached confluence after 6-7 days of culture. On day 7, the DMEM medium containing 10% FBS was removed and the wells were filled with 1 ml 1 ml of PBS and rinse twice with 1 ml of DMEM, 2 mM L-glutamine + 1% P / S +0.1% BSA was added. On day 8, the medium was removed and 500 μl of DMSO was added per well.

[0298] OA induction by intra-articular (IA) injection of MIA Animals were anesthetized by chamber induction technique using inhalation anesthesia (isoflurane 5%). During the procedure, the animals were maintained under isoflurane at a level of 1.5-3% and an air flow rate of 1-2 liters. The area around the knee joint was wiped with alcohol. MIA was administered in a volume of 0.75 mg. 5 μl of the solution was injected intra-articularly (IA) through the patellar tendon. Using a 30-gauge 0.5-inch needle attached, only a 2-3 mm needle can puncture the joint. After injection, the knee was massaged to ensure uniform distribution of the solution. The mice were injected once on day 1 (groups 2M, 3M, 4M, and 5M). Group 1M (sham control) 5 μl of saline for injection was injected into the knee joint.

[0300] Sham mice were randomly assigned to group 1M on day 1. MIA-injected mice were Group allocation was made on day 3 based on BW. [Table 17]
[0301] Testing and Evaluation Animal sacrifice and tissue collection On day 11 (the end date), the mice were euthanized. The knee joint structures (including the synovium) were collected. The samples were rapidly frozen in liquid nitrogen. RNA was extracted using the SV Total RNA Isolation System Kit (Promega). ega) according to the manufacturer's recommendations. PCR analysis was performed. SOX9 is the first transcription factor essential for chondrocyte differentiation and cartilage formation. has been identified as a factor.
[0302] result SOX9 RTqPCR analysis of knee joint structures As shown in Figure 16, the vehicle administered 0.75 mg of MIA to the knee joint on day 1 Mice (Group 2M) had significantly higher SOX9 relative expression on day 11 compared to vehicle sham controls (Group 1M). On day 3, MIA-injected mice were treated with albumin-containing liraglutide. When the mice received intra-articular injection of liraglutide, SOX9 expression was restored, and the expression of SOX9 was significantly higher in group 3M (liraglutide 10 μg). and Group 4M (liraglutide 20 μg) were the same as the sham control Group 1M. In the group 5M receiving 30 μg of methicillin, the relative expression of SOX9 was 5.5 compared with the sham control group 1M. It has increased by 5%.
[0303] conclusion The purpose of the study was to evaluate the efficacy of intra-articular administration of compounded liraglutide in the treatment of monoiodoacetate injection mice. The objective of this study was to perform RTqPCR of SOX9 in the knee joint of rats.
[0304] The monoiodoacetate (MIA) model is a deformable model in both rats and mice. It has become the standard for modeling joint destruction in osteoarthritis (OA). delivered a single injection of MIA into the knee joint and administered glyceraldehyde-3-phosphatase dehydrogenase (Glyceraldehyde-3-phosphatase dehydrogenase). It inhibits glycolysis in chondrocytes by inhibiting glycogenase, and specifically induces chondrocyte death. Chondrocytes differentiated after condensation of mesenchymal stem cells produce collagen and proteoglycans. The transcription factor SOX9 is responsible for the secretion of extracellular matrix molecules. Using this animal model of OA, we found that compared with sham healthy controls, Intra-articular injection of compounded liraglutide restored or increased SOX9 relative expression. On the other hand, we showed that SOX9 expression was decreased after MIA injection.
[0305] Therefore, this study demonstrated that topically administered albumin-combined liraglutide has the potential to improve the Targeting the relevant mechanisms related to anabolism in MIA-induced OA and inflammatory pain models in This indicates that
