Lasseter,Mark Kipnes,Karen Snyder,Deborah Hilliard,Michael Tanen,Caroline Cilissen,Marina De Smet,Inge De Lepeleire,Kristien Van Dyck,Amy Qiu Wang,Wei Zeng,Michael J. Davies,Wesley Tanaka,Jens J. Holst,Carolyn F. Deacon,Keith Gottesdiener,John A. Wagner +26 more
TL;DR: In patients with type 2 diabetes, near maximal glucose-lowering efficacy of sitagliptin after single oral doses was associated with inhibition of plasma DPP-4 activity of 80% or greater, corresponding to a plasma sitgliptin concentration of 100 nm or greater and an augmentation of active GLP-1 and GIP levels of 2-fold or higher after an OGTT.

TL;DR: Sitagliptin is an orally active, potent, and selective inhibitor of dipeptidyl peptidase IV (DPP‐IV) currently in phase III development for the treatment of type 2 diabetes.
Journal ArticleDOI
Pharmacokinetic and pharmacodynamic properties of multiple oral doses of sitagliptin, a dipeptidyl peptidase-IV inhibitor: a double-blind, randomized, placebo-controlled study in healthy male volunteers.
Arthur J. Bergman,Catherine Stevens,YanYan Zhou,Bingming Yi,Martine Laethem,Marina De Smet,Karen Snyder,Deborah Hilliard,Wesley Tanaka,Wei Zeng,Michael Tanen,Amy Qiu Wang,Li Chen,Gregory A. Winchell,Michael J. Davies,Steven Ramael,John A. Wagner,Gary A. Herman +17 more
TL;DR: Assessment of the pharmacokinetic and pharmacodynamic properties and tolerability of multiple oral once-daily or twice-daily doses of sitagliptin found a finding consistent with near-maximal acute glucose lowering in preclinical studies.
Journal ArticleDOI
Pharmacokinetics and pharmacodynamic effects of the oral DPP-4 inhibitor sitagliptin in middle-aged obese subjects.

TL;DR: In nondiabetic obese subjects, treatment with sitagliptin 200 mg bid was generally well tolerated without associated hypoglycemia and led to maximal inhibition of plasma DPP‐4 activity, increased active GLP‐1, and reduced glycemic excursion.
Journal ArticleDOI

TL;DR: The metabolism and excretion of [14C]sitagliptin, an orally active, potent and selective dipeptidyl peptidase 4 inhibitor, were investigated in humans after a single oral dose of 83 mg/193 μCi, indicating that sitagli leptin was eliminated primarily by renal excretion.
