FDA has approved saxagliptin and metformin XR (Kombiglyze XR, AstraZeneca and Bristol-Myers Squibb) tablets for the treatment of type 2 diabetes in adults. Kombiglyze XR is the first and only once-a-day metformin XR plus DPP-4 inhibitor combination tablet offering strong glycaemic control across glycosylated hemoglobin levels, fasting plasma glucose and post-prandial glucose.
In a multinational, placebo-controlled, double-blind trial, the selective vitamin D receptor activator paricalcitol (Zemplar, Abbott Laboratories), at doses of 1 µg or 2 µg daily, reduced albuminuria in patients with type 2 diabetes, who were already being treated with renin-angiotensin-aldosterone system inhibitors.
Metformin, either alone or in combination with sulfonylurea, appears to increase 1-year and long-term survival in patients with type 2 diabetes mellitus and chronic heart failure, according to research published in the October 1 issue of the American Journal of Cardiology, HealthDay News reported.
A systematic review assessing the comparative effectiveness of oral antidiabetic drugs for preventing patients at high risk from progressing to type 2 diabetes has found glitazones, biguanides, and alpha-glucosidase inhibitors reduced the relative risk of diabetes by as much as 63%, whereas insulin secretagogues had no effect.
New molecular entity: Saxagliptin (Onglyza), a DPP-4 inhibitor, was approved on July 31, 2009, for the treatment of type 2 diabetes mellitus
Initiation of antipsychotic therapy associated with hyperglycemia in older diabetic patients
Liraglutide is a glucagon-like peptide-1 (GLP-1) analogue that is currently pending FDA approval for the treatment of type 2 diabetes. This agent mimics the actions of food-induced endogenous GLP-1 release, thus causing glucose-dependent increased insulin secretion, decreased glucagon secretion, and reduced appetite and gastric emptying.
Labeling updates and warnings through April 2009 for insulin pens and cartridges
Compared with biguanides, thiazolidinediones, meglitinides, and second-generation sulfonylureas, metformin is the sole oral therapy associated with a decreased risk of cardiovascular (CV) mortality in patients with type 2 diabetes, according to a meta-analysis published in the Archives of Internal Medicine.
In a survey of trends in diabetes treatment from 1994 to 2007, investigators observed an increasing incidence of diabetes, a greater variety of drugs and combinations available for treatment, and a marked increase in the annual cost of diabetes medications.
Alogliptin is a highly selective DPP-IV inhibitor under investigation for the treatment of type 2 diabetes. An NDA for alogliptin was submitted in January 2008, and a response from FDA is expected in the fourth quarter of this year.
Drug Watch: Agents in late-stage development for the treatment of types 1 and 2 diabetes mellitus (September 2008)
A recent multinational, randomized, double-blind, placebo-controlled clinical trial demonstrated that administration of aliskiren provides additional renal protection to patients with hypertension, type 2 diabetes mellitus, and nephropathy who are already receiving optimal antihypertensive therapy and renal protective therapy with the angiotensin receptor blocker (ARB) losartan.
Among the new data presented at the 68th Scientific Sessions of the ADA were the results of phase 3 trials of the investigational agents liraglutide, ABT-335, saxagliptin, and alogliptin.
Drug Watch: Agents in late-stage development for the treatment of type 2 diabetes mellitus (August 2008)
Lacosamide safely decreases pain scores in patients with painful diabetic neuropathy, according to a pooled efficacy and safety analysis presented at the 60th Annual Meeting of the American Academy of Neurology, Chicago.
Treatment of diabetes with DPP-IV inhibitors; sitagliptin, vildagliptin, alogliptin, and saxagliptin.
Colesevelam (Welchol) was approved on January 18, 2008, as an adjunct to diet and exercise to improve glycemic control in adult patients with type 2 diabetes.
The use of rosiglitazone to treat type 2 diabetes in older patients has been associated with an increased risk of cardiovascular events.
In a multicenter, multinational, randomized controlled study, a fixed-dose combination of perindopril/ indapamide was associated with a reduced risk of death and vascular events in patients with type 2 diabetes, many of whom were already taking antihypertensive drugs.
An extensive systematic review published in the Annals of Internal Medicine demonstrated that older oral drugs for type 2 diabetes are just as, if not more, effective than newer agents for gylcemic control, lipid control, and other intermediate end points.
Nebivolol, an investigational (NDA submitted) vasodilating beta-blocker, demonstrated a neutral effect on blood glucose levels in two 12-week clinical studies of patients with hypertension.
Investigators have demonstrated that patients with type 2 diabetes who use inhaled insulin as part of their basalbolus insulin regimen experience a small decline in pulmonary function.
An open-label extension study of exenatide demonstrated sustained blood glucose control and weight loss in patients with type 2 diabetes.
A quick-release formulation of bromocriptine reduces the incidence of diabetic cardiovascular complications in patients with type 2 diabetes and improves glycemic control in those patients who did not achieve HbA1c <7.5% with metformin plus a sulfonylurea.
