  • angiopoietin-like 3 ANGPTL3 mRNA and protein
  • methods, compounds, and compositions having an ANGPTL3 inhibitor for reducing ANGPTL3 related diseases or conditions in an animal are useful, for example, to treat, prevent, delay or ameliorate any one or more of cardiovascular disease or metabolic syndrome, or a symptom thereof, in an animal.
  • Diabetes and obesity are interrelated in that obesity is known to exacerbate the pathology of diabetes and greater than 60% of diabetics are obese. Most human obesity is associated with insulin resistance and leptin resistance. In fact, it has been suggested that obesity may have an even greater impact on insulin action than diabetes itself (Sindelka et al., Physiol Res., 2002, 51, 85-91). Additionally, several compounds on the market for the treatment of diabetes are known to induce weight gain, a very undesirable side effect to the treatment of this disease.
  • Cardiovascular disease is also interrelated to obesity and diabetes. Cardiovascular disease encompasses a wide variety of etiologies and has an equally wide variety of causative agents and interrelated players. Many causative agents contribute to symptoms such as elevated plasma levels of cholesterol, including non-high density lipoprotein cholesterol (non-HDL-C), as well as other lipid-related disorders. Such lipid-related disorders, generally referred to as dyslipidemia, include hyperlipidemia, hypercholesterolemia and hypertriglyceridemia among other indications. Elevated non-HDL cholesterol is associated with atherogenesis and its sequelae, including cardiovascular diseases such as arteriosclerosis, coronary artery disease, myocardial infarction, ischemic stroke, and other forms of heart disease. These rank as the most prevalent types of illnesses in industrialized countries. Indeed, an estimated 12 million people in the United States suffer with coronary artery disease and about 36 million require treatment for elevated cholesterol levels.
  • TG circulating triglyceride
  • VLDL very low density lipoproteins
  • Metabolic syndrome is a combination of medical disorders that increase one's risk for cardiovascular disease and diabetes.
  • the symptoms including high blood pressure, high triglycerides, decreased HDL and obesity, tend to appear together in some individuals. It affects a large number of people in a clustered fashion. In some studies, the prevalence in the USA is calculated as being up to 25% of the population. Metabolic syndrome is known under various other names, such as (metabolic) syndrome X, insulin resistance syndrome, Reaven's syndrome or CHAOS.
  • the angiopoietins are a family of secreted growth factors. Together with their respective endothelium-specific receptors, the angiopoietins play important roles in angiogenesis.
  • angiopoietin-like 3 also known as angiopoietin-like protein 3, ANGPT5, ANGPTL3, or angiopoietin 5
  • ANGPT5 angiopoietin-like protein 3

  • GWAS Genome-wide association scans
  • ANGPTL3 Mice deficient in ANGPTL3 have very low plasma triglyceride (TG) and cholesterol levels, while overpexpression produces the opposite effects (Koishi et al. 2002; Koster 2005; Fujimoto 2006).

No. 13/520,997; PCT Publication WO 2011/085271; incorporated by reference herein, in their entirety) have previously been suggested or developed, but none of the compounds directly targeting ANGPTL3 have been approved for treating cardiometabolic disease.
