The FLOW trial was stopped early based on an interim analysis that found the study met the criteria for efficacy.
DREAM trial: Rosiglitazone reduces the incidence of new-onset diabetes
November 1st 2006In 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.
DREAM trial: Ramipril fails to reduce the incidence of new-onset diabetes or death
November 1st 2006In 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.
Rimonabant: A novel CB1 receptor antagonist for the treatment of obesity
November 1st 2006Obesity 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.
Effect of a medication assistance program on clinical outcomes in patients with diabetes
October 1st 2006Approximately 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
Vildagliptin: A dipeptidyl peptidase-IV inhibitor for the treatment of type 2 diabetes
October 1st 2006Despite 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.
Elevated atorvastatin dosage reduces rate of cardiovascular events in CHD patients
September 1st 2006Intensive 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.
Sitagliptin: The first dipeptidyl peptidase IV inhibitor for the treatment of type 2 diabetes
September 1st 2006A 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.

Anticonvulsant lacosamide exhibits pain reduction in phase 3 diabetic neuropathy trial
July 1st 2006The 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.
Intensive control of type 1 diabetes results in fewer cardiovascular events over the long term
March 1st 2006Tight 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).
A growth hormone conversion program and patient outcomes at a not-for-profit HMO
February 1st 2006Although 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).
Pharmacologic options for the management of diabetic peripheral neuropathy
December 1st 2005Diabetic peripheral neuropathy, one of the most common late complications of diabetes, is associated with decreased quality of life and increased morbidity. The pathophysiology of diabetic neuropathy (DN) is multifactorial, contributing to ischemic and painful events and neuronal damage.
Contraindicated metformin fares well in heart failure patients with diabetes
December 1st 2005In an observational study of patients with type 2 diabetes being treated for heart failure, researchers found that metformin—whether used alone in vulnerable patients or in combination—is associated with lower mortality, less morbidity, and fewer hospitalizations compared with sulfonylurea monotherapy. The study, conducted in Canada, was published in Diabetes Care.
ACEIs, ARBs decrease new-onset type 2 diabetes in patients with hypertension, CAD, and HF
November 1st 2005ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) possess a similar and significant ability to reduce the development of new-onset type 2 diabetes among patients with hypertension, coronary artery disease, and heart failure, according to a meta-analysis study published in Diabetes Care.
Pre-meal inhaled insulin lowers HbA1c levels more effective than rosiglitazone
November 1st 2005Inhaled insulin (Exubera, Pfizer/Sanofi-Aventis) could be an effective therapy and alternative to rosiglitazone (Avandia, GlaxoSmithKline) for individuals who are early into the course of type 2 diabetes, according to a study published in Diabetes Care.
Dual peroxisome proliferator-activated receptor agonist demonstrates significant lipid benefits
August 1st 2005Phase 3 clinical trial results have demonstrated that the dual alpha/gamma peroxisome proliferator-activated receptor (PPAR) agonist muraglitazar achieves significant beneficial lipid effects compared with pioglitazone, and the agent also provides long-term glycemic control in type 2 diabetics. The results were reported during the American Diabetes Association (ADA) 65th Annual Meeting in San Diego, Calif.

Type 2 diabetes therapies may increase HF risk
May 1st 2005The use of any pharmacological therapy for type 2 diabetes appears to be associated with an increased risk of heart failure (HF). However, the risk does not extend beyond the first year after diagnosis and does not appear to differ among the types of drug therapy, according to researchers who assessed 25,680 patients in the UK General Practice Research Database between 1988 and 1999. The researchers categorized person-time drug exposures to monotherapies in insulin, sulfonylureas (SUs), metformins, and other oral hypoglycemic agents (OHA), and combination therapy including insulin, combination therapy without insulin, and triple combination therapy with or without insulin.
