Insulin Dose and Cardiovascular Mortality in the ACCORD Trial

Diabetes Care

2015 ABSTRACT: In the ACCORD trial, intensive treatment of patients with type 2 diabetes and high cardiovascular (CV) risk was associated with higher all-cause and CV mortality. Post hoc analyses have failed to implicate rapid reduction of glucose, hypoglycemia, or specific drugs as the causes of this finding. We hypothesized that exposure to injected insulin was quantitatively associated with increased CV mortality.

IDegLira Improves Both Fasting and Postprandial Glucose Control as Demonstrated Using Continuous Glucose Monitoring and a Standardized Meal Test

Journal of Diabetes Science and Technology

2015 ABSTRACT: IDegLira is a novel, fixed-ratio combination of the long-acting basal insulin, insulin degludec, and the long-acting glucagon-like peptide-1 analog liraglutide. We studied the effect of IDegLira versus its components on postprandial glucose (PPG) in type 2 diabetes.

More realistic power estimation for new user, active comparator studies: an empirical example

Pharmacoepidemiology and Drug Safety

2015 ABSTRACT: Pharmacoepidemiologic studies are often expected to be sufficiently powered to study rare outcomes, but there is sequential loss of power with implementation of study design options minimizing bias. We illustrate this using a study comparing pancreatic cancer incidence after initiating dipeptidyl-peptidase-4 inhibitors (DPP-4i) versus thiazolidinediones or sulfonylureas.

Benefits of combination of insulin degludec and liraglutide (IDegLira) are independent of baseline HbA1c and duration of type 2 diabetes

Diabetes, Obesity & Metabolism

2015 ABSTRACT: IDegLira is a novel combination of a basal insulin (insulin degludec [IDeg]) and a glucagon-like peptide-1 receptor agonist (liraglutide) available as a once-daily injection for patients with type 2 diabetes (T2D). The present post hoc analyses evaluated whether IDegLira was consistently effective regardless of the stage of T2D progression.

The Primary Glucose-Lowering Effect of Metformin Resides in the Gut, Not the Circulation. Results From Short-term Pharmacokinetic and 12-Week Dose-Ranging Studies

Diabetes Care

2015 ABSTRACT: Delayed-release metformin (Met DR) is formulated to deliver drug to the lower bowel to leverage the gut-based mechanisms of metformin action with lower plasma exposure. Met DR was assessed in two studies. Study 1 compared the bioavailability of single daily doses of Met DR to currently available immediate-release metformin (Met IR) and extended-release metformin (Met XR) in otherwise healthy volunteers. Study 2 assessed glycemic control in subjects with type 2 diabetes (T2DM) over 12 weeks.
