AI Technical Summary
Existing GLP-1 receptor agonists like semaglutide effectively reduce body weight but are associated with dose-dependent gastrointestinal disturbances and rapid weight regain after treatment cessation, while ACAT inhibitors show promise in weight loss and insulin resistance reduction, but their combination with GLP-1RAs is underexplored for improved efficacy and tolerability.
Co-administration of therapeutically effective amounts of GLP-1 receptor agonists and ACAT inhibitors, such as semaglutide and avasimibe, either in formulations or separately, to target weight control by modulating adipogenesis and lipid metabolism.
The combination achieves significant and sustained weight loss, reduces food intake, and improves metabolic markers without the adverse effects seen with GLP-1RAs alone, demonstrating enhanced efficacy and tolerability.

Abstract
Description
[Technical Field]
[0001] The present invention relates to compositions comprising one or more GLP-1 receptor agonists and one or more ACAT inhibitors, and methods for controlling weight by co-administering one or more GLP-1 receptor agonists and one or more ACAT inhibitors. [Background technology]
[0002] Obesity is characterized by an increase in fat mass due to an increase in the size and number of adipocytes. Enlarged adipocytes increase the uptake of free cholesterol, leading to its accumulation in lipid droplets in proportion to the increased triglyceride content.

The success of semaglutide in treating obesity has resulted in double-digit weight loss rates and led to its clinical approval. However, concerns have arisen regarding dose-dependent gastrointestinal disturbances associated with semaglutide and rapid weight regain after treatment cessation. These concerns have prompted a search for new semaglutide therapies that may offer greater efficacy and improved tolerability.

[0040] Prodrug derivatives of the compounds of the invention may be prepared by methods known to those skilled in the art (see, for example, Saulnier et al., Bioorg Med. Chem. Letters, 1994, 4, 1985, which is incorporated herein by reference, for further details). Protected derivatives of the compounds of the invention may be prepared by means known to those skilled in the art. A detailed description of the techniques applicable to the creation of protecting groups and their removal can be found in T.W.

Bundgaard, Protecting Groups in Organic Chemistry, Elsevier, 1985.
[0041] The compounds of the present disclosure may be prepared as stereoisomers. If the compounds possess at least one chiral center, they may exist as enantiomers. If the compounds possess two or more chiral centers, they may exist as diastereomers. The compounds of the present invention may be prepared as racemic mixtures. Alternatively, the compounds of the present invention may be prepared as individual enantiomers or diastereomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers, and recovering the optically pure enantiomer. Separation of enantiomers may be accomplished using covalent diastereomeric derivatives of the compounds of the present invention or dissociable complexes (e.g., crystalline diastereomeric salts). Diastereomers have different physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be readily separated by exploiting these dissimilarities. Diastereomers can be separated by chromatography or separation / resolution techniques based on differential solubility. The optically pure enantiomers are then recovered along with the resolving agent by any practical means that does not result in racemization. A more detailed description of the techniques applied to the separation of stereoisomers of compounds from racemic mixtures can be found in the book Jean Jacques, Andre Collet and Samuel H. Wilen, "Enantiomers, Racemates and Separations", John Wiley and Sons, Inc., 1981, which is incorporated herein by reference.
[0042] The compounds of the present invention may be prepared as solvates (e.g., hydrates). The term "solvate" refers to a complex of variable stoichiometry formed by a solute (e.g., a compound of the present invention or a pharmaceutically acceptable salt thereof) and a solvent. For the purposes of the present invention, such solvents do not interfere with the biological activity of the solute. Non-limiting examples of suitable solvents include water, acetone, methanol, ethanol, and acetic acid. Preferably, the solvent used is a pharmaceutically acceptable solvent.

[0054] Example 1: Materials and Methods 1. Animal care and drug administration Cohort 1: The first set of animal experiments was conducted at the ChemOn Inc. nonclinical laboratory, and the experimental procedures were approved by the Animal Care and Use Committee (serial number: 2021-09-007). Eight-week-old male C57BL / 6 mice were purchased from Orient Bio Inc., Korea. After 2 weeks of acclimation, they were fed a high-fat diet (HFD) (catalog number: D12492, Research Diets Inc.) for 12 weeks to allow DIO to develop. These mice were then randomly assigned to a control group, avasimibe group, semaglutide group, or combination group. Avasimibe solution was prepared to a final concentration of 10 mg / kg body weight as described in Y. Zhu, S. Q. Kim, Y. Zhang, Q. Liu, and K. H. Kim, "Pharmacological inhibition of acyl-coenzyme A: cholesterol acyltransferase attenuates obesity and insulin resistance in diet-induced obese mice by modulating food intake," Metabolism 123 (2021) 154861. Semaglutide stock solution, prepared in DMSO (1 mg / ml), was diluted with PBS to a final concentration of 0.04 mg / kg body weight. Mice were injected subcutaneously with this drug solution or vehicle solution at a volume of 10 μl / g body weight daily for the indicated days.
[0055] Cohort 2: The second set of animal experiments was conducted in accordance with a protocol approved by the Purdue University Animal Care and Use Committee (Protocol Number: 11129000347). Male C57BL / 6 DIO mice were purchased from the Jackson Laboratory. After 8 weeks of HFD treatment, mice were randomly assigned to the same groups as in Cohort 1: control, avasimibe, semaglutide, and combination treatment. Avasimibe (20 mg / kg body weight) and semaglutide (0.04 mg / kg body weight) were prepared as in Cohort 1, and the drugs were injected subcutaneously every 3 days for 23 days. Mice were housed in a humidity- and temperature-controlled facility under a 12-hour / 12-hour light / dark cycle with free access to food and water.
[0056] 2.Body composition and blood analysis Immediately before sacrificing the second cohort of mice, changes in body composition (e.g., fat mass, lean body mass, free water, and total water) were assessed using EchoMRI (Echo Medical Systems). Blood samples were collected after a 3-h fast and stored frozen until analysis. Aspartate transaminase (AST), alanine aminotransferase (ALT), glucose, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were also measured (AU680 Chemistry Analyzer, Beckman Coulter). Serum leptin (catalog number: ab100718, Abcam) and insulin (catalog number: ab277390, Abcam) were determined by enzyme-linked immunosorbent assay kit, and cholesterol / CE (catalog number: ab65359, Abcam) was determined by enzymatic assay according to the manufacturer's instructions.
[0057] 3. Oral glucose tolerance test (OGTT) Mice were fasted for 6 h (07:00–13:00) before oral administration of D-glucose (2 g / kg BW). Tail blood samples were collected before glucose loading (0 min) and at 15, 30, 60, 90, and 120 min after glucose loading, and blood glucose levels were measured using a CONTOUR® NEXT glucometer (Ascensia Diabetes Care, Parsippany, NJ, USA).
[0058] 4. Tissue Harvesting and Histological Measurement of Adipocyte Size Upon animal sacrifice, the adipose tissue was washed with saline, fixed in 10% neutral formalin buffer, and embedded in paraffin. The tissue was then cut into 4 μm sections, stained with hematoxylin and eosin (H&E), and cell size (~100 cells / mouse) was measured using ImageJ software (NIH).
[0059] 5.Statistical analysis Data are presented as mean ± SEM, and analyses were performed using GraphPad Prism 9.4.1 (GraphPad). Comparisons between experimental and control groups were performed by one-way ANOVA (Figures 1C, 2C, 2E, 2F, 2G, 3A, 3B, 3G) or two-way ANOVA (Figures 1B, 1D, 2B, 2D), followed by Tukey's post-hoc test. Differences were considered significant at p ≤ 0.05. For comparisons between two groups, Student's t-tests were performed in some of Figures 1B and 1E.
[0060] Example 2: Daily Administration—Body Weight and Food Intake of DIO Mice Cohort 1 mice were used to investigate the effects of combined administration of semaglutide and low-dose avasimibe compared with semaglutide injection alone in morbidly obese mice (Figure 1A). On day 1 of the experiment, the average mouse weight was recorded at 48.84 ± 2.26 g (Figure 1B). After 4 weeks of treatment, the weights of mice in the semaglutide and combination groups reached a plateau and were significantly lower than those of mice maintained on a normal diet, so the mice were sacrificed (data not shown). Mice in the vehicle control and avasimibe groups were treated for an additional 16 days before sacrifice (Figure 1A). Over the first 4 weeks, the average weight of vehicle-treated animals increased by 1.2% compared to their starting weight. In contrast, the mean weight changes in mice treated with avasimibe, semaglutide, or the combination of both drugs were -6.29%, -21.66%, and -30.47% of their starting weight, respectively (Figure 1C). Notably, administration of a low dose of avasimibe (10 mg / kg BW) alone resulted in only a modest weight loss compared to our previous findings, in which a 24% weight loss was achieved by daily intraperitoneal administration of 20 mg / kg BW avasimibe for 14 days (see references Y. Zhu, S. Q. KIM, Y. Zhang, Q. Liu, K. H. KIM, 2014, incorporated herein by reference). "Pharmacological inhibition of acyl-coenzyme A:cholesterol acyltransferase attenuates obesity and insulin resistance in diet-induced obese mice by modulating food intake," Metabolism 123 (2021) 154861. Consequently, in subsequent studies using a second cohort of mice, the dose of avasimibe was increased to 20 mg / kg BW. The weight loss observed after semaglutide and combination therapy was attributed to a rapid suppression of food intake compared with mice treated with vehicle or avasimibe alone (Figure 1D). However, as the treatment regimen continued, food intake gradually returned to baseline levels, and the effect of semaglutide diminished around day 26. Furthermore, organ weight measurements confirmed that all fat depots sampled were reduced in mice treated with the combination therapy compared with those treated with semaglutide (Figure 1E). Although kidney weights showed no significant differences, liver and brain weights were significantly increased in the combination group compared with the semaglutide group (Figure 1E). To investigate the potential toxic effects of combination therapy on the liver, plasma ALT and AST levels were measured. Both ALT and AST levels were higher in the combination group compared with the semaglutide group and were similar to those seen in the vehicle control group (Table 1). These results suggest that repeated subcutaneous administration of semaglutide and avasimibe resulted in greater weight loss, primarily due to a reduction in fat mass in DIO mice.
[0061] [Table 1]
[0062] Values are mean ± SEM of n=10 mice / group (ALT, alanine aminotransferase; AST, aspartate transaminase; CE, cholesteryl ester; HDL, high-density lipoprotein; LDL, low-density lipoprotein; NS, not significant; TG, triglycerides). For comparisons between two groups sacrificed on the same day, values were analyzed using Student's t-test. * indicates a significant difference between the vehicle and avasimib groups sacrificed on day 43, and § indicates a significant difference between the semaglutide and combination groups.
[0063] Example 3: Cholesterol and leptin levels in daily dosing-DIO mice To assess whether avasimib could enhance the plasma lipoprotein profile and major lipid components associated with obesity, plasma samples from mice in Cohort 1 were analyzed. Daily subcutaneous administration of avasimib at 10 mg / kg BW for 6 weeks did not significantly reduce cholesterol or CE levels compared with vehicle administration (Table 1). However, 4 weeks of combination treatment significantly reduced both free cholesterol and CE levels compared with semaglutide alone (Table 1). Because mice naturally lack CE transfer protein and store most of their cholesterol in HDL, the reduction in circulating cholesterol levels in the combination group was also reflected in HDL levels. (References Z. Kaabia, J. Poirier, M. Moughaizel, A. Aguesse, S. Billon-Crossouard, F. Fall, M. Durand, E. Dagher, M. Krempf, M. Croyal, "Plasma lipid analysis reveals strong similarities in lipid fingerprints of humans, hamsters, and mice compared with other animal species," Sci Rep. 8 (2018) 15893.) Interestingly, avasimib did not improve triglyceride (TG) levels; rather, they increased in the combination group compared with the semaglutide group, reaching levels comparable to those in the vehicle control group (Table 1). Furthermore, circulating leptin levels were significantly lower in the combination group compared with the semaglutide group, indicating a reduction in the fat fraction in adipose tissue. In this study, the avasimib group showed lower glucose levels compared with the vehicle group, and the combination group showed lower glucose levels compared with the semaglutide group, but the difference in insulin levels did not reach statistical significance (Table 1). In summary, repeated subcutaneous administration of semaglutide and avasimib in combination proved effective in lowering circulating cholesterol and glucose levels without improving TG levels. The reduction in fat mass with combination administration was further supported by the observation that plasma leptin levels were lower in DIO mice.
[0064] Example 4: Every 3 Days Dosing - Body Weight and Food Intake of DIO Mice To examine the effects of combined semaglutide and avasimibe administration in DIO mice and mimic the once-weekly semaglutide regimen in humans, we utilized Cohort 2 mice (Figure 2A). On day 1, the average mouse weight was recorded at 37.37 ± 3.58 g. During the treatment period, mice in the vehicle group continued to gain weight, reaching an average weight of 41.58 ± 4.74 g, a 10.07% increase from their starting weight (Figure 2B). In contrast, mice receiving subcutaneous administration of avasimibe alone or in combination with semaglutide every three days successfully prevented weight gain induced by the HF diet. Specifically, the average weight loss in mice treated with avasimibe, semaglutide, and the combination of both drugs was 0.82%, 8.56%, and 14.89% of their starting weight, respectively (Figure 2C). Notably, each administration of semaglutide initially reduced food intake, which then recovered within 48 hours. The compensatory effect on food intake became more pronounced by the seventh administration, and by day 22, food intake in the semaglutide and combination groups exceeded that of the vehicle group (Figure 2D). However, cumulative food intake analysis revealed that mice in the combination group ate less food than mice in the vehicle group throughout the entire experimental period (Figure 2E). Next, to verify the suggested improvement in glucose metabolism by avasimibe, an OGTT was performed (Figures 2F and 2G). Subcutaneous administration of avasimibe alone every 3 days did not enhance glucose tolerance or amplify the hypoglycemic effect of semaglutide. These results suggest that the combination of semaglutide and avasimibe resulted in a greater percentage of weight loss compared to the effect observed with semaglutide alone in moderately obese mice, which showed little improvement in glucose tolerance.
[0065] Example 5: Fat mass and adipocyte size in DIO mice treated every 3 days Next, we tested whether the enhanced weight loss observed in the combination group was mediated by avasimib-induced reduction in fat mass. Only the combination group showed a significant reduction in fat mass compared to the vehicle group (Figure 3A). However, when examining the weights of different adipose tissues, no significant differences were observed between groups due to the high variability (Figure 3B). Furthermore, we found that fat mass correlated more strongly with body weight than lean mass (Figure 3C and Figure 3D). Among various adipose tissues, the weight of inguinal adipose tissue best represented total fat mass (Figure 3E). Because hypertrophic adipocytes are known to exhibit impaired insulin response and secrete proinflammatory cytokines [16-18], we analyzed digital images of H&E-stained inguinal fat layers (Figure 3F and Figure 3G). The avasimib group showed a significantly higher proportion of small adipocytes (5,001-10,000 μm²) and a lower proportion of large adipocytes (20,001-100,000 μm²) compared with the vehicle group. The semaglutide group showed a lower proportion of large adipocytes (40,001-100,000 μm²) compared with the vehicle group. However, no significant changes in adipocyte size distribution were observed in the combination group. Taken together, these findings suggest that combination treatment reduced fat mass in DIO mice, in part due to a reduction in adipocyte size by avasimib.
