Context: Optimal management of type 2 diabetes remains an elusive goal. Combination therapy addressing the core defects of impaired insulin secretion and insulin resistance shows promise in maintaining glycemic control.
Objective: The aim of the study was to assess the efficacy and tolerability of alogliptin combined with pioglitazone in metformin-treated type 2 diabetic patients.
Objective: To assess the efficacy and tolerability of alogliptin plus pioglitazone for initial combination therapy in drug-naïve type 2 diabetic patients.
Research Design And Methods: This 26-week, double-blind, parallel-group study randomized 655 patients with inadequately controlled type 2 diabetes to four arms: 25 mg alogliptin (A25) q.d.
Objective: The dipeptidyl peptidase-4 inhibitor alogliptin, under development for treatment of Type 2 diabetes, primarily is excreted renally. This study investigated (1) the effect of food on alogliptin pharmacokinetics and tolerability and (2) pharmacokinetic interactions between alogliptin and metformin or cimetidine and tolerability of alogliptin when administered with either drug.
Methods: This randomized, open-label, two-phase, crossover study recruited healthy adults.
Objectives: To compare the efficacy and safety of alogliptin, a dipeptidyl peptidase-4 (DPP-4) enzyme inhibitor, in elderly (> or =65) and younger (<65) patients with type 2 diabetes mellitus.
Design: Pooled analysis of six randomized, double-blind, placebo-controlled studies of alogliptin.
Participants: Patients aged 18 to 80 with type 2 diabetes mellitus and inadequate glycemic control.
Aims: To assess the efficacy and safety of alogliptin added to insulin in patients with type 2 diabetes inadequately controlled with insulin alone or combined with metformin.
Methods: In this 26-week, double-blind, placebo-controlled study, 390 patients were randomized to receive alogliptin 12.5 mg (n = 131), alogliptin 25 mg (n = 129) or placebo (n = 130) once daily, as add-on to stable insulin therapy with or without metformin.
Objectives: To evaluate the efficacy and safety of alogliptin in patients with type 2 diabetes inadequately controlled by therapy with a thiazolidinedione (TZD).

Aim: To evaluate the efficacy and safety of alogliptin, a potent and highly selective dipeptidyl peptidase-4 (DPP-4) inhibitor, in combination with glyburide in patients with type 2 diabetes inadequately controlled by sulphonylurea monotherapy.
Methods: After a 2-week screening period, adult patients 18-80 years of age entered a 4-week run-in/stabilization period in which they were switched from their own sulphonylurea medication to an equivalent dose of glyburide (open label) plus placebo (single blind). After the run-in period, patients were randomly assigned to double-blind treatment with alogliptin 12.
Objective: To evaluate the dipeptidyl peptidase-4 (DPP-4) inhibitor alogliptin in drug-naïve patients with inadequately controlled type 2 diabetes.
Research Design And Methods: This double-blind, placebo-controlled, multicenter study included 329 patients with poorly controlled diabetes randomized to once-daily treatment with 12.5 mg alogliptin (n = 133), 25 mg alogliptin (n = 131), or placebo (n = 65) for 26 weeks.
Background: Alogliptin is a highly selective dipeptidyl peptidase-4 (DPP-4) inhibitor that is under development for the treatment of type 2 diabetes.
Objective: This study was conducted to characterize the pharmacokinetics, pharmacodynamics, and tolerability of single oral doses of alogliptin in healthy male subjects.
Methods: This was a randomized, double-blind, placebo-controlled study in which healthy, nonobese male subjects between the ages of 18 and 55 years were assigned to 1 of 6 cohorts: alogliptin 25, 50, 100, 200, 400, or 800 mg.
Background: Alogliptin is a highly selective dipeptidyl peptidase-4 (DPP-4) inhibitor that is under development for the treatment of type 2 diabetes (T2D).
Objectives: This study was conducted to evaluate the pharmacokinetic (PK), pharmacodynamic (PD), and tolerability profiles and explore the efficacy of multiple oral doses of alogliptin in patients with T2D.
Methods: In this randomized, double-blind, placebo-controlled, parallel-group study, patients with T2D between the ages of 18 and 75 years were assigned to receive a single oral dose of alogliptin 25, 100, or 400 mg or placebo (4:4:4:3 ratio) once daily for 14 days.

Tacrolimus (FK506, Prograf), marketed for the prophylaxis of organ rejection following allogenic liver or kidney transplantation, is virtually completely metabolized. The major metabolic pathways are P450 3A4-mediated hydroxylation and demethylation. Since P450 hepatic drug-metabolizing enzymes may be impaired in hepatic dysfunction, a study was conducted to characterize oral and intravenous tacrolimus pharmacokinetics in 6 patients with mild hepatic dysfunction and compared with parameters to those from normal subjects obtained in a separate study.

Tacrolimus (FK506, Prograf) is marketed for the prophylaxis of organ rejection following allogenic liver or kidney transplantation. A previously conducted, randomized, 24-subject, crossover bioavailability study of 1 and 5 mg capsules (one period each) failed to demonstrate bioequivalence. A single-dose, four-period, four-sequence, randomized, crossover, replicate study (N = 32) was therefore used to evaluate the bioequivalence of the marketed 1 and 5 mg capsules in healthy volunteers.
