BACKGROUND The feasibility, safety, and efficacy of prolonged use of an artificial beta cell (closed-loop insulin-delivery system) in the home setting have not been established. METHODS In two multicenter, crossover, randomized, controlled studies conducted under free-living home conditions, we compared closed-loop insulin delivery with sensor-augmented(More)
OBJECTIVE To evaluate the feasibility of day and night closed-loop insulin delivery in adults with type 1 diabetes under free-living conditions. RESEARCH DESIGN AND METHODS Seventeen adults with type 1 diabetes on insulin pump therapy (means ± SD age 34 ± 9 years, HbA1c 7.6 ± 0.8%, and duration of diabetes 19 ± 9 years) participated in an open-label(More)
OBJECTIVE To compare two validated closed-loop (CL) algorithms versus patient self-control with CSII in terms of glycemic control. RESEARCH DESIGN AND METHODS This study was a multicenter, randomized, three-way crossover, open-label trial in 48 patients with type 1 diabetes mellitus for at least 6 months, treated with continuous subcutaneous insulin(More)
OBJECTIVE To assess the effect of a 4-week adjunctive therapy of exenatide (EXE) (5-10 microg b.i.d.) or sitagliptin (SITA) (100 mg once daily) in response to a standardized breakfast meal challenge in 48 men or women with type 2 diabetes receiving insulin glargine (GLAR) + metformin (MET). RESEARCH DESIGN AND METHODS This was a single-center, randomized,(More)
OBJECTIVE Because there are limited data on the comparison of insulin aspart and mixed insulin in type 2 diabetes, this trial was performed to compare the efficacy and safety of preprandial insulin aspart with human soluble insulin (HI) and human premix (70% NPH/30% regular) insulin (MIX). RESEARCH DESIGN AND METHODS A total of 231 type 2 diabetic(More)
AIM Because of its zinc-free formulation insulin glulisine (GLU) might have a faster onset of action than other short-acting analogues. We compared the pharmacokinetics and pharmacodynamics of GLU with those of insulin aspart (ASP). METHODS Twelve healthy subjects, aged 18-65 years, participated in this randomized, double-blind, crossover trial. Subjects(More)
This pedagogical review illustrates the differences between pharmacokinetic (PK) and pharmacodynamic (PD) measures, using insulin therapy as the primary example. The main conclusion is that PD parameters are of greater clinical significance for insulin therapy than PK parameters. The glucose-clamp technique, the optimal method for determining insulin PD, is(More)
AIMS Regular human insulin (RHI) at high doses shows prolongation of its duration of action potentially leading to late postprandial hypoglycaemia. This study compared late metabolic activity (4-12 and 6-12 h post-dosing) and duration of action (time to reach late half-maximal activity) over a range of doses between insulin aspart (IAsp) and RHI. METHODS(More)
INTRODUCTION This randomized, double-blind, placebo-controlled, single and multiple ascending-dose study evaluated the pharmacodynamic effects and safety/tolerability of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in patients with type 2 diabetes. METHODS Patients (N = 116) discontinued their antihyperglycemic medications 2 weeks before(More)
BACKGROUND AND AIMS The aim of this study was to compare blood glucose and plasma insulin profiles after bolus insulin infusion by a patch pump (PP) versus a conventional pump (CP), directly after placement and after Day 3 of use. PATIENTS AND METHODS Twenty patients with type 1 diabetes came in for two blocks of visits: one block of two visits while(More)
