 USE OF A PYRAZOLE DERIVATIVE FOR THE PREPARATION OF MEDICAMENTS USEFUL IN THE PREVENTION AND TREATMENT OF METABOLIC SYNDROME.

 The present invention relates to the use of a pyrazole-derived cannabinoid CB1 receptor antagonist compound for the preparation of medicaments useful in the prevention and treatment of dyslipidemias, metabolic syndrome, cardiovascular risks associated with obesity and associated with dyslipidemia.

 Obesity is now recognized as one of the major public health problems. Correlated with a large number of cardiovascular diseases, including arteriosclerosis, diabetes, cancers, respiratory disorders, it is associated with an increase in the mortality rate. The annual costs of somatic complications of obesity are estimated by the World Health Organization (WHO) at one-third of the global health budget.

 Dyslipidemia is defined by elevated triglycerides, LDL-c (English Low Density Lipoprotein Cholesterol), low concentration of HDL-c (English High Density Lipoprotein Cholesterol), increased total cholesterol / HDL-c, by the presence of small particles of LDL. This dyslipidemia, often present in the obese subject, is also recognized as having an atherogenic profile, that is to say that increases the risk of atheromatous disease.

 Metabolic syndrome refers to a set of risk factors including dyslipidemia (low HDL-c, elevated triglycerides), increased abdominal circumference / obesity, but also insulin resistance (hyperglycaemia). fasting), and high blood pressure. This syndrome affects millions of people around the world, putting them at greater risk of developing diabetes with complications of kidney failure and retinopathy and cardiovascular complications, or of causing cardiovascular disease, such as coronary artery disease, coronary heart disease, myocardial infarction, angina, atherosclerosis, arteriosclerosis, stroke, thrombosis, atherothrombosis or glaucoma. By improving each parameter of the metabolic syndrome, particularly by preventing and treating the constitutive elements of dyslipidemia and obesity, the prevention and treatment of the metabolic syndrome of at-risk patients may help to reduce the onset of cardiovascular disease and type 2 diabetes.

 The definition of the metabolic syndrome is not universally unified, that given by the National Cholesterol Education Program (NCEP), within the framework of an expert group ATP III (of the English Adult Treatment Panel III) retains the listed criteria in the following table. Patients have a metabolic syndrome when they meet at least 3 of the 5 criteria indicated: increase in abdominal circumference / obesity, dyslipidemia, high blood pressure, hyperglycemia.

EXAMPLE 1 Action of rimonabant on serum lipid levels in obese mice.

 The effect of long-term (2 months) treatment with rimonabant was studied in mice with established obesity.

 The study was conducted in mice receiving either a normal diet or a fatty diet. Obesity developed in mice on a fat diet and stabilized after 5 months. The mice were then divided into 3 groups: group 1: fat diet and oral treatment for 2 months with rimonabant 10 mg / kg / day, in water with 0.1% Tween 80; group 2: maintenance of the fat diet and administration of the vehicle (Tween 80); group 3: return to a normal diet and administration of the vehicle (Tween 80); group 4 consists of mice receiving from the beginning a normal diet and the vehicle.

<Desc / Clms Page number 8>

 After 5 months of fat diet, the mice showed a weight gain of 46% and a marked increase in serum levels of leptin, insulin, glucose and total cholesterol.

The HDLc (high density lipoprotein cholesterol) and LDLc (low density lipid cholesterol) levels were measured for these obese mice, and there was an increase in these levels, accompanied by a decrease in of the report
HDLc / LDLc.

 After 2 months of treatment with rimonabant, the weight of the group 1 mice decreased by 34.5 ~ 0.8 g, ie in the same proportions as that of the group 3 mice brought back to a normal diet (33.7 ~ 0.6 g).

 Similarly, after 2 months of treatment, the group 1 mice showed a reduction in serum levels of leptin, insulin and glucose, and similarly these levels were reduced for group 3 mice.

The data measured in cholesterol triglyceride and lipoprotein assays are reported in the tables below:

n: number of animals.

 According to Tables 2 and 3, rimonabant treatment, as administered to group 1 animals, corrects the mild hypertriglyceridemia observed in animals fed a fat diet.

 From Tables 2 and 3 it can be seen that treatment with rimonabant can lower total cholesterol but not normalize it; this same treatment makes it possible to normalize the level of LDLc with the consequence of increasing the HDLc / LDLc ratio.

 It can be concluded that treatment with rimonabant produces favorable changes in the plasma lipid profile, even though the mice are kept on a fatty diet: indeed, although the reduction in total cholesterol is modest, the treatment normalizes the level of triglycerides and LDLc while maintaining a high level of the "protective" level of HDLc, thus the HDLc / LDLc ratio is greater in animals that have been treated with rimonabant than in animals treated by the vehicle alone, whether they have been on a fat or normal diet.

 EXAMPLE 2: rimonabant on the lipid parameters in clinic, after 4 weeks.

 A clinical trial was conducted for 4 weeks on 287 obese patients whose body mass index (BMI) was between 30 and 40. The patients were randomized to receive doses of 5, 10 or 20 mg / day of rimonabant or placebo, after receiving placebo for 2 weeks.

 A control visit was performed 4 weeks after the end of treatment.

<Desc / Clms Page number 10>

 During the course of the study, patients were asked to follow a low-calorie diet (deficit of 500 kcal / day).

The results observed at the end of the treatment are reported in the following table:

* p <0.005 versus the placebo group.

 ** p <0.01 versus the placebo group.

 *** p <0.05 versus the placebo group.

 It has been found that weight loss in subjects treated with rimonabant is accompanied by a tendency to lower triglycerides and increase HDLc. At the same time, patients' blood glucose levels remained stable or decreased discreetly for patients in rimonabant-treated groups, while blood glucose levels in placebo patients increased.

 In obese patients, the influence of rimonabant treatment on various biological parameters was considered in the evaluation of the metabolic syndrome as defined by ATP III. This results in a tendency to improve the metabolic syndrome in patients treated with rimonabant.

 EXAMPLE 3: Rimonabant on lipid parameters and the prevalence of the metabolic syndrome in clinic, after 12 months.

 The Rio Lipids clinical study, conducted for 12 months in 1036 obese subjects with dyslipidemia compares the effect of rimonabant to the 20 mg dose versus a placebo product in reducing weight, improving lipid parameters and the prevalence of the syndrome metabolic. The treated group and the placebo group are subjected to a low calorie diet.

 Subjects treated at 20 mg for 12 months had a greater weight loss of 6.3 + 0.5 kg compared to the placebo group (p <0.001).

<Desc / Clms Page number 11>

 In this same population, the increase in HDL-c is 11.3 to 1.7% higher than in the placebo group.

 The decrease in triglyceride levels in the treated group was 12.2 to 3.7% higher (p = 0.001) than in the placebo group.

 Adiponectin was also increased from 5.8-2.7 g / ml to 8.2 4.2 g / ml at the end of the year of treatment with 20 mg rimonabant.

 Adiponectin reflects the state of insulin resistance: the variation of its rate is inversely proportional to that of insulin resistance. Thus, in the present case, the increase in the adiponectin level indicates the decrease in the rate of insulin resistance.

 Finally, in the treated group 60.2% of patients stopped presenting the characteristics of the metabolic syndrome, while the proportion was 40.4% in the placebo group (p <0.001).

 Thus, in a one-year clinical trial, the effect of rimonabant on the parameters of dyslipidemia, on several elements constituting the metabolic syndrome and on the metabolic syndrome itself is observed.
