Though medical treatment has been effective in the treatment of cardiometabolic diseases (including coronary atherosclerosis and diabetes mellitus), the incidence of these disorders continues to be high. Many reasons are responsible, but lifestyle changes, including an increased prevalence of obesity and the metabolic syndrome, are significant for this cause. Recent reported guidelines by the JNC-VII and National Cholesterol Education Panel/ATP-III suggest that blood pressure reduction is effective in improving the overall quality of life and may be helpful in the prevention of cardiovascular disease.
Diagnosis and treatment of obese patients with hypertension requires that health care providers address the issues of hypertension, glucose intolerance, body weight and dyslipidemia. Strategies to promote therapeutic lifestyle change (TLC), specifically increased physical activity and reduced dietary intake resulting in weight loss, are not as well defined. A sedentary lifestyle and poor cardiorespiratory fitness are not only associated with the (cardio) metabolic syndrome but could actually be considered features of the metabolic syndrome. These issues are significant in the health of certain individuals, who experience greater difficulty in treated BP control, experience increased hypertensive and diabetic complications, and have higher levels of obesity.
In this study, the investigators will evaluate the efficacy of the nutritional supplements berberine, alpha-lipoic acid, and picrorhiza (CAR-191) when consumed 30 minutes before meals, on appetite suppression, body composition and weight control. Additionally, the investigators will evaluate the effects of this combination of nutraceuticals on the mechanistic effects of oxidation, inflammation, and vascular function in a high-risk population with the metabolic syndrome.
The investigators will evaluate the initiation of CAR-191 in patients which meet at least 3 of the 5 criteria (ATP-III guidelines) for the cardiometabolic syndrome. The investigators will determine whether the CAR-191 combination as compared to placebo provides benefit in appetite suppression, body composition and certain clinical endpoints, including effects on endothelial function, lipid levels, and glucose control. This study will analyze the effects of 12 week administration of CAR-191 versus placebo on these parameters in a population of patients (n=40) with the cardiometabolic syndrome. The study has a parallel design consisting of 2 weeks of washout and then 12 weeks of treatment to either CAR-191 or placebo. The total study period is 14 weeks. Patients will be assigned to the CAR-191 or placebo group in a 3:1 ratio so that 30 patients will receive CAR-191 and 10 patients will receive placebo. See attached study design.
Primary Objective To assess the comparative effect of a combination (known as CAR-191) of berberine (200 mg), alpha-lipoic acid (150 mg), and picrorhiza (100 mg) three times a day, compared to placebo three times a day, on parameters relate to appetite suppression, weight control and body composition in a high risk population with the metabolic syndrome.
Secondary Co-objectives
To evaluate the effects of CAR-191 versus placebo on changes in:
- Endothelial function using noninvasive brachial artery reactivity (BAR) ultrasound
- Biomarkers including IL-6, HOMA-IR, HbA1C, hsCRP, adiponectin, plasma/urine isoprostanes, PAI-1, TNFα-II, aldosterone, and glutathione redox ratio
- Urinary protein excretion
- Clinical chemistry including plasma glucose, blood urea nitrogen, creatinine, total bilirubin, uric acid, transaminases (SGOT/AST, SGPT/ALT), alkaline phosphatase, C-reactive protein, and lipoproteins
