Definitions

  • the present invention relates to endocrinology, physiology and pharmacology. More particularly, it relates to methods and compositions for treating conditions associated with insulin resistance.
  • Insulin resistance is a multi-factorial disease characterized by the requirement of inappropriately high levels of insulin for maintaining glucose homeostasis. It is a relatively common disorder that accompanies obesity, type-2 diabetes, type-2 pre-diabetes, several disorders including essential hypertension, ventricular dysfunction with or without congestive symptoms, post- surgical stress, trauma, polycystic ovary syndrome, burns, gestational diabetes associated with pregnancy, sepsis, myocardial infarction, and stroke, and follows therapy with certain hormones such as glucocorticoids and growth hormone.
  • Insulin resistance is one of the fundamental components of the insulin resistance syndrome, also known as "syndrome X” or "metabolic syndrome". It is characterized by glucose intolerance, hypertriglyceridemia, reduced levels of high-density lipoprotein cholesterol, hyperinsulinemia and central obesity. Other manifestations of the disease include hypertension, albuminuria, increased serum levels of plasminogen activator inhibitor and increased serum uric acid.
  • Insulin resistance is an independent risk factor for the development of atherosclerotic vascular disease, which may cause myocardial infarction, stroke, peripheral vascular disease and death. More recently, the insulin resistance and hyperinsulinemia associated with obesity have been linked to cardiac hypertrophy in young individuals.
  • Metformin and the thiazoladinediones are presently the only drugs available that increase insulin sensitivity. They are effective oral agents for treating the early stages of diabetes, without affecting endogenous secretion of insulin from the pancreas. These drugs may delay or prevent the onset of the later, insulin-dependent phase, as it is widely believed that chronic overproduction of insulin by pancreatic ⁇ -cells secondary to profound insulin resistance leads to depletion of ⁇ -cell mass and subsequent insulin-dependent diabetes.
  • insulin resistance is a risk factor for cardiovascular disease, it often accompanies myocardial infarction and heart failure.
  • insulin resistance develops or is exacerbated by the rise in neurohormones (e.g. catecholamines, glucocorticoids, TNF- ⁇ , etc.) that frequently accompanies these disorders.
  • Metformin and thiazoladinediones are not adequate drugs for treating insulin resistance associated with cardiovascular disease. Metformin is contraindicated in patients with heart disease due to the risk of metabolic acidosis.
  • thiazoladinediones are known to cause fluid retention and can precipitate congestive heart failure in patients with left ventricular dysfunction.
  • Insulin resistance also affects skeletal muscle independently of other diseases. It impairs vasodilatation of skeletal muscle blood vessels, reduces transport capacity of glucose into skeletal muscle cells and alters the ratio of fatty acid oxidation versus glucose oxidation as an energy source for oxidative phosphorylation . These effects reduce exercise capacity and contribute independently to ambulatory limitation in obesity and in various cardiovascular diseases, including heart failure.
  • the available drugs, metformin and the thiazoladinediones have limited use and are contraindicated in patients with heart disease. Accordingly, there is a need for new and better compositions and methods for treating insulin-resistance conditions or disorders.
  • glucagon-like peptide-1 (GLP-1) is capable of reversing insulin resistance.
  • the present invention relates to methods for treating insulin resistance-associated conditions using GLP-1.
  • the insulin resistance-associated condition is selected from the group consisting of type-2 pre- diabetes, atherosclerotic cardiovascular disease (ASCD) , drug-induced insulin resistance, congestive heart failure, diminished exercise capacity of skeletal muscle, and left ventricular dysfunction with cardiac metabolic myopathy or diminished exercise capacity of skeletal muscle, with the proviso that said congestive heart failure is not associated with toxic hypervolemia .

  • insulin regulating refers to an ability to control the release of insulin into the circulation, in relation to blood glucose and fatty acid levels.
  • the terms "therapeutically or pharmaceutically effective” or “therapeutically or pharmaceutically effective amount” refers to an amount of the compound of this invention required to reduce or lessen the severity of insulin resistance for some period of time.

  • the present invention relates to methods for treating conditions associated with insulin resistance in a subject. The methods include administering to a subject a therapeutically effective amount of GLP-1. The methods of this invention further relate to decreasing insulin resistance using GLP-1.
  • GLP-1 plays a key role in the regulation of plasma glucose homeostasis. It is involved in regulating insulin secretion in relation to blood glucose and/or lipid levels, and inhibiting glucagon release by the pancreas, inhibiting gastric acid secretion and motility, and suppressing appetite and food intake. GLP-1 is a member of the incretin group of secretagogue hormones that are released from the intestinal enteroendocrine cells in response to the ingestion of food. GLP-1 binds to the GLP-1 receptors, some of which are expressed on the ⁇ -cells of the pancreas.
  • GLP-1 Binding of GLP-1 to its receptor triggers an intracellular signaling pathway that results in controlling insulin secretion with concomitant inhibition of glucagon production. This in turn leads to uptake of glucose in muscle and fat cells and the inhibition of hepatic glucose production, all of which lowers blood glucose levels.
  • GLP-1 is also capable of increasing insulin sensitivity.
  • GLP-1 is an intestinally produced peptide hormone. Under physiological conditions, GLP-1 is secreted in response to a meal (Kreymann, B. et al.,

  • Insulin resistance also develops as an associated disease that contributes to overall morbidity and mortality in other diseases, such as congestive heart failure which is not associated with toxic hypervolemia, left ventricular dysfunction secondary to myocardial injury and diminished skeletal muscle exercise capacity.
  • Neurohormones such as catecholamines, glucagon, cortisol, growth hormone and cytokines such as TNF- ⁇ are all known to induce insulin resistance alone or in combination.
  • these neurohormones initiate insulin resistance in the aforementioned diseases, as associated stress causes many of the neurohormones to be secreted into the blood. In other cases, the neurohormones may simply exaggerate the underlying resistance.
  • Insulin resistance alters the metabolism and function of tissues that use both fatty acids and glucose as substrates for oxidative phosphorylation (e.g., oxygen-dependent ATP synthesis) . This is most evident in cardiac and skeletal muscle. For example, in diseases associated with severely depressed left ventricular dysfunction and reduced peripheral blood flow, insulin resistance develops subsequent to the rise in serum neurohormones. The resistance is tantamount to insulin deficiency.
