Incretin mimetic approved as adjunctive therapy in type 2 diabetes mellitus not adequately controlled by a thiazolidinedione
The American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) have developed a consensus algorithm for the management of hyperglycemia in type 2 diabetes. The statement, published in the August issue of Diabetes Care, was created for several reasons.
In a randomized, double-blind, placebo-controlled trial recently published in Lancet, the thiazolidinedione (or "glitazone") rosiglitazone statistically significantly reduced the incidence of new-onset diabetes when given to patients diagnosed with prediabetes but lacking a prior history of cardiovascular disease. The benefits of using thiazolidinediones in the treatment of patients with diabetes are well known, but the current finding that thiazolidinediones can prevent prediabetics from progressing to diabetes is novel.
In a randomized, double-blind, placebo-controlled trial, the angiotensin-converting enzyme (ACE) inhibitor ramipril, when administered to patients with prediabetes but no previous cardiovascular disease, failed to demonstrate a statistically significant reduction in the primary composite end point of new-onset diabetes or death.
Obesity is on the rise in the United States, with 60.5% of the adult population overweight and 23.9% obese as of 2005. Up to 10% of an industrialized country's healthcare budget often can be spent on obesity and associated comorbidities.
Patients taking clozapine for schizophrenia should be regularly monitored because of an increased risk for metabolic abnormalities, according to a study published in the American Journal of Psychiatry.
Approximately 17 million people in the United States have type 2 diabetes, and the prevalence continues to rise.1 More than 45% of patients with end-stage renal disease have type 2 diabetes as an etiology, and a patient with type 2 diabetes has the same risk of developing an acute coronary syndrome (unstable angina, myocardial infarction [MI]) over the next 10 years as someone who has had an acute coronary syndrome in the past.2 In addition to these complications, type 2 diabetes also increases the risk of blindness, neuropathy, and amputation.3
Despite the variety of medications available to treat type 2 diabetes, the disease is inadequately controlled in many patients. In order to improve glycemic control, manufacturers are pursuing compounds that affect the incretin hormones that stimulate insulin release in response to increased glucose levels. Although stimulation of the incretin receptors by the glucagon-like peptide-1 (GLP-1) enhances the body's ability to produce insulin in response to elevated blood glucose concentrations, the clinical usefulness of GLP-1 is limited by its rapid degradation by dipeptidyl peptidase-IV (DPP-IV). Drug companies have developed compounds intended to act as inhibitors of DPP-IV. Vildagliptin (Galvus, Novartis) is the second DPP-IV inhibitor under investigation by FDA to offer this new mechanism to achieve glycemic control. An NDA for vildagliptin was submitted to FDA in March 2006, 1 month after the submission of the first DPP-IV inhibitor, sitagliptin.
Three studies presented at the 10th International Conference on Alzheimer's Disease and Related Disorders in Madrid, Spain, yielded new data regarding the relationship between diabetic and pre-diabetic conditions and the subsequent development and treatment of Alzheimer's disease (AD).
Intensive therapy with atorvastatin 80 mg/d, in comparison with the same medication at 10 mg/d, significantly reduced the rate of major cardiovascular events by 25% in patients with clinically evident stable coronary heart disease (CHD) and diabetes, according to a study published in Diabetes Care.
Atorvastatin showed no statistically significant difference in the reduction of a composite cardiovascular disease (CVD) end point in type 2 diabetes patients, according to a randomized, double-blind, parallel-group study.
A variety of clinical approaches are utilized in the management of poor glycemic control in patients with type 2 diabetes. Sitagliptin (Januvia, Merck), a novel drug in a new medication class known as dipeptidyl peptidase-IV (DPP-IV) inhibitors, offers a new mechanism by which to achieve glycemic control. Although stimulation of receptors by the glucagon-like peptide-1 (GLP-1) enhances the body's ability to produce insulin in response to elevated blood glucose concentrations, rapid degradation of GLP-1 by DPP-IV limits its clinical effectiveness. The development of medications to reduce this degradation is being pursued by numerous manufacturers. An NDA for the first of these medications, sitagliptin, was submitted to FDA in February 2006. Currently available clinical studies have demonstrated improved glycemic control with sitagliptin therapy in patients who have not achieved target glucose levels with diet and oral medications.

The anticonvulsant lacosamide is effective in relieving diabetic neuropathy and produces increased pain reduction with continued treatment for 22 months, according to phase 3 study results presented during the 25th Annual Scientific Meeting of APS in San Antonio, Texas. "This is a promising treatment that maintains a long-term effect," said Tibor Hidvegi, MD, Medical Department, Petz Hospital, Gyor, Hungary.
Tight glucose control for a mean period of 6.5 years produces long-lasting cardiovascular benefits in patients with type 1 diabetes, according to a study published in the New England Journal of Medicine (NEJM).
Although experience tells us that formulary conversion programs are commonplace, they are discussed fairly infrequently in the literature. A recent MEDLINE search did not identify any conversion programs similar to a human growth hormone (HGH) program implemented at HIP Health Plan of New York (HIP-NY).
