COMPOUNDS FOR PREVENTION AND TREATMENT OF OBESITY AND RELATED

DISORDERS

FIELD OF THE INVENTION

[0001] The present invention relates to uses of compounds for the treatment and/or prevention of obesity, inducing weight loss and/or suppressing apatite.

BACKGROUND

[0002] Obesity is an common clinical disorder in both highly developed and newly emerging countries. Over 300 million adults are deemed to be clinically obese worldwide. There is also substantial clinical and epidemiological evidence accumulated to date that reveals that obesity is correlated with cardiovascular disease, hypertension, and diabetes.

[0003] The National Institutes of Health offers a suggested definition of obesity as a body mass index (or“BMI”) of 30 and above. BMI correlates strongly in adults with the total body fat content. BMI can be mathematically calculated by dividing a subject’s weight (in kilograms) by a subject’s height (in meters squared). A BMI of 30 typically suggests that a subject is 30 pounds overweight.

[0004] Despite all of the existing research, there appears to be a very limited number of ways to generate a meaningful weight loss for an obese human.

SUMMARY

[0005] Presented herein, in certain aspects, is a method of treating or preventing obesity, assisting or inducing weight loss, suppressing apatite, and/or inhibiting weight gain in a subject which method comprises administering a therapeutically effective amount of a compound disclosed herein (e.g., sometimes referred to herein as a compound of the invention) to a subject. In some embodiments, a compound of the invention comprises a structure of any one of

Formulas I to IV disclosed herein, or a pharmaceutically acceptable salt, stereoisomer or tautomer thereof. In certain embodiments, a compound of the invention is included in a pharmaceutical composition. In some embodiments, a compound of the invention comprises the structure of Formula IV ; or a pharmaceutically acceptable salt, stereoisomer or tautomer thereof.

[0006] In some embodiments a subject is human. In some embodiments a compound of the invention is administered at a dose of 0.1 mg/kg to 100 mg/kg. In some embodiments a compound of the invention is administered at a dose of 5 mg/kg to 100 mg/kg. In some embodiments a compound of the invention is administered once per day, or twice per day. In certain embodiments, a compound of the invention is administered orally or intravenously.

[086] Terminal Mean Body Weights are shown in Table 6.

TABLE 6 - Terminal Mean Body Weights

[087] Compared to Group 1 controls, group mean body weight in males was decreased 5.9 and 16.2% at 100 and 300 mg/kg/day males on Day 28. Compared to Group 1 controls, group mean body weight in females was decreased 6.9 and 12.4% at 100 and 300 mg/kg/day for females on Day 28. Group mean weight gain from Day -1 to 28 for males in Groups 1 and 2 was 175 and 180 grams, respectively, while mean body weight gains for Group 3 and 4 males was 150 and 101 grams, respectively.

[088] Group mean weight gain from Day -1 to 28 for females in Groups 1 and 2 was 47 and 45 grams, respectively while mean body weight gains for Groups 3 and 4 females were 28 and 13 grams, respectively.

[089] These alterations in body weight and body weight gain were often statistically significant, particularly at the high dose level, and were considered related to test article exposure.

[090] During the recovery period, group mean body weight gain for both males and females at 300 mg/kg/day exceeded that seen in the vehicle-treated controls. Full recovery of body weight and body weight gain was seen during the recovery period.

Food Consumption

[091] Mean Food Consumption is shown in Table 7 (Males) and Table 8 (Females).

[092] Food consumption was decreased at 100 and 300 mg/kg/day in both sexes compared to Group 1 controls. Food consumption decreases at 300 mg/kg/day in both sexes were often statistically significant and at 100 mg/kg/day were sometimes statistically significant. Compared to Group 1 controls, group mean food consumption from Days 21 to 28 in males was decreased 4.9 and 16.7% at 100 and 300 mg/kg/day, respectively. Compared to Group 1 controls, group mean food consumption from Days 21 to 28 in females was decreased 8.6 and 15.6% at 100 and 300 mg/kg/day, respectively.

[093] These alterations in food consumption were considered related to test article exposure.

[094] Group mean food consumption during the recovery period was similar between the vehicle-treated control and 300 mg/kg/day animals indicating full recovery of food consumption during the recovery period. Summary of Results and Discussion

[095] Dose formulation analysis showed formulations were accurately prepared, homogenous, and stable for the duration of use. Incurred sample re-analysis (ISR) of

bioanalytical plasma samples did not pass acceptance criteria. Additionally, analysis of Day 28 samples also occurred outside the known long-term stability (LTS) range of the validated bioanalytical method. Thus, the bioanalytical and toxicokinetic results for J147 are considered to be for information only. The bioanalytical and toxicokinetic analysis results should also be considered in light of the fact that Day 28 samples were analyzed outside of their LTS.

[096] Noteworthy clinical observations during the 28-day treatment period were confined to soft feces noted in some animals of both sexes at 300 mg/kg/day. Body weight, body weight gain, and food consumption were decreased at 100 and 300 mg/kg/day in both sexes. A general decrease in activity was noted as evidenced by decreased distance traveled, ambulatory time, horizontal counts, vertical counts, and vertical breaks, and an increase in resting time in the motor activity portion of the Functional Observational Battery (FOB) conducted on Day 1. These alterations were evident in males at all dose levels and in females at 100 and 300 mg/kg/day. While treatment-related, these neurobehavioral findings were not considered adverse. There were no noteworthy clinical observations during the recovery period, and J147-related effects on body weight and food consumption were reversible following cessation of treatment. At the end of the 28-day treatment period, mean red blood cell counts, hematocrit, and hemoglobin values were decreased in males at all dose levels and in females at 100 and 300 mg/kg/day. Mean platelet and reticulocyte counts were increased at all dose levels in both sexes. Prothrombin time was decreased in both sexes at all dose levels. Decreased mean serum glucose concentrations were noted in males at 100 mg/kg/day and in both sexes at 300 mg/kg/day. Decreased mean serum triglyceride concentrations were noted in males at 100 and 300 mg/kg/day. Effects on serum glucose and triglyceride concentrations were considered secondary to decreased food consumption during the treatment period. Urinalysis revealed increased levels of urinary ketones in males at 300 mg/kg/day. There were no anatomic pathology correlates to these clinical pathology findings. At the end of the 14-day recovery period, test article-related effects on serum triglyceride concentrations and red cell mass persisted in animals previously administered 300 mg/kg/day J147 for 28 days. [097] There were no alterations noted at 30 mg/kg/day which were considered related to test article administration. Decreased activity as seen in the motor activity test of the FOB, and increased platelet and reticulocyte counts seen at this dose level, were not considered adverse findings. Though there were indicators of decreased activity in the FOB, decreased activity was never called at any dose level as a clinical observation and, with the exception of a few instances of hair loss, there were no clinical observations of any sort at 30 mg/kg/day. The increases in platelet counts at 30 mg/kg/day in females was small (3.8%) and in males the increases were not dose proportional. The increased reticulocyte counts were considered an adaptive response to the decreases in RBC parameters.

[098] At the terminal necropsy, enlarged liver and small thymus were seen in one or two animals at 300 mg/kg/day. Group mean liver weights were increased in males at all dose levels and in females at 100 and 300 mg/kg/day. Decreases in group mean thymus weights were seen in both sexes at 100 and 300 mg/kg/day. Microscopically, subacute perivascular inflammation was noted in the liver of both sexes at 300 mg/kg/day, and hepatocellular hypertrophy was seen in both sexes at 100 and 300 mg/kg/day. The incidence of single cell necrosis of acinar cells in the pancreas was increased at 300 mg/kg/day in both sexes and increased in males at 100 mg/kg/day. Additionally, thymic lymphoid depletion was noted in both sexes at 300 mg/kg/day. Findings of increased liver weight and hepatocellular hypertrophy were considered to represent an adaptive response rather than an adverse or toxicological effect. There were no J 147-related organ weight, macroscopic or microscopic findings in high-dose (300 mg/kg/day) animals on Day 43 following a 2- week treatment-free recovery period.

Conclusion

[099] Accurate measures of test article exposure were not available as the toxicokinetic data were considered in light of the fact that plasma sample incurred sample re-analysis did not meet acceptance criteria and Day 28 samples were analyzed outside their long-term stability window. Given that there was clear evidence of toxicity at the mid and high dose groups, the Study Director believes that this study met the objective of examining the toxicity profile of J147. The study did not meet the objective of examining the toxicokinetic profile of J 147 following oral exposure. Under the conditions of this study, the no-observed-adverse-effect-level (NOAEL) for J147 was considered to be 30 mg/kg/day. Day 1 Cmax and AUCO-last values at the NOAEL were 146 ng/mL and 835 hr*ng/mL, respectively, in males and 50.8 ng/mL and 233 hr*ng/mL, respectively, in females. Cmax and AUCO-last values should be considered in light of the caveats mentioned in the preceding paragraph. The lowest-observed-adverse-effect-level (LOAEL) is 100 mg/kg/day in both sexes based on test article-related decreases in body weight/body weight gain and food consumption, decreased activity, decreases in measures of red blood cell mass, decreased prothrombin time, decreased serum glucose and triglycerides, decreased thymus weights, and single cell necrosis of pancreatic acinar cells in males.

Example 2

[0100] J147 or vehicle was administered once daily to beagle dogs via oral gavage for up to 28 days at a daily dose of 0, 30, 100 and 300 mg/kg. J174 was prepared in a vehicle formulation comprising 5% ethanol, 5% DMSO and 90% corn oil (v/v/v). Block Lab Diet (Certified Canine Diet #5007, PMI Nutrition International, Inc.) was offered via limited feedings, except during designated periods. The animals were offered food 2 hours post-dose on each dosing day for 2 to 5 hours. Food was offered 2 to 5 hours/day during the acclimation period and during the recovery period. Tap water was available ad libitum via an automatic watering system. The study protocol is shown below in Table 9.

TABLE 9

[0101] Body weight and body weight gain were decreased in all J 147-treated groups (both sexes) compared to the vehicle-treated control group. Day 28 group mean body weight values for males were decreased by 23% and 26% at 30 and 100 mg/kg/day, respectively. Group mean body weight for 300 mg/kg/day males on Day 22 was decreased 18% versus the Day 28 control value. Day 28 group mean body weight values for females were decreased by 19% and 21% at 30 and 100 mg/kg/day, respectively. Group mean body weight for 300 mg/kg/day females on Day 21 was decreased by 23% versus the Day 28 control value. High-dose (300 mg/kg/day) recovery animals (males and females) gained weight rapidly during the recovery period indicating full recovery of body weight and body weight gain during the 14-day recovery period.

[0102] Food consumption was decreased in all J147-treated groups (both sexes) compared to the vehicle-treated control group. Day 28 group mean food consumption values for males were decreased by 31% and 39% at 30 and 100 mg/kg/day, respectively. Group mean food

consumption for 300 mg/kg/day males on Day 22 was decreased by 48% versus the Day 28 control value. Day 28 group mean food consumption values for females were decreased by 45% and 48% at 30 and 100 mg/kg/day, respectively. Group mean food consumption for 300 mg/kg/day females on Day 21 was decreased by 38% versus the Day 28 control value. High-dose (300 mg/kg/day) recovery animals (males and females) showed dramatic and immediate increases in food consumption during the recovery period, indicating rapid and full recovery of food consumption during the 14-day recovery period.

Example 3

[0103] J 147 was administered once daily to beagle dogs via oral gavage for up to 28 days at a daily dose of 0, 1, 10 and 30 mg/kg. J174 was prepared in a vehicle formulation comprising 5% ethanol, 5% DMSO and 90% com oil (v/v/v). Block Lab Diet (Certified Canine Diet #5007,

PMI Nutrition International, Inc.) was offered via limited feedings, except during designated periods. The animals were offered food 2 hours postdose on each dosing day for 2 to 5 hours. Food was offered 2 to 5 hours/day during the acclimation period and during the recovery period. Tap water was available ad libitum via an automatic watering system. The study protocol is shown below in Table 10.

TABLE 10

[0104] Body weight loss with lower food consumption was noted in Groups 3 and 4 at doses levels of 10 mg/kg/day and 30 mg/kg/day. At 10 mg/kg/day, 3 of 4 males and 4 of 4 females lost weight (up to -9% compared to pre-test levels). At 30 mg/kg/day, 5 of 6 males and 6 of 6 females lost weight (up to -12% and -17%, respectively, of pretest levels). The results are summarized in Table 11 (males), Table 12 (females), and Figures 1 and 2. Body weight gain during a 14-day recovery period was comparable to control values in both sexes at 30 mg/kg/day (e.g., see Fig. 1C and ID). It was noted that although animals in Group 3 did only experience moderate weight loss, they did not experience the weight gain observed for the control animal of Group 1. Consequently, it was concluded the J 147 induces weight loss and inhibits weight gain. This result may have been due, at least in part, to apatite suppression as observed in Fig. 2.

The term“about” as used herein refers to a value within 10% of the underlying parameter (i.e., plus or minus 10%), and use of the term“about” at the beginning of a string of values modifies each of the values (i.e.,“about 1, 2 and 3” refers to about 1, about 2 and about 3). For example, a weight of “about 100 grams” can include weights between 90 grams and 110 grams. The term,

“substantially” as used herein refers to a value modifier meaning“at least 95%”,“at least 96%”,“at least 97%”,“at least 98%”, or“at least 99%” and may include 100%. For example, a composition that is substantially free of X, may include less than 5%, less than 4%, less than 3%, less than 2%, or less than 1% of X, and/or X may be absent or undetectable in the composition.
