ArmTypeInterventionsDescription
Obese nondiabetic insulin resistant subjects- Panel AActive comparatorDrug: Continous IV infusion of Nesiritide; Drug: Hyperinsulinemic euglycemic clamp; Drug: PlaceboIV nesiritide 3 pmol/kg/min or placebo for nesiritide
Obese nondiabetic insulin resistant subjects- Panel BActive comparatorDrug: Continous IV infusion of Nesiritide; Drug: Hyperinsulinemic euglycemic clamp; Drug: PlaceboIV nesiritide 2 pmol/kg/min or placebo for nesiritide
  • Continous IV infusion of Nesiritide (Drug): Nesiritide (fhBNP) administered by continuous IV infusion during 48 hours.
  • Hyperinsulinemic euglycemic clamp (Drug): 48 hours IV infusion of nesiritide on insulin sensitivity (IS) measured by two-step hyperinsulinemic euglycemic clamp in obese nondiabetic insulin resistant subjects.
  • Placebo (Drug): 48 hours of placebo.

+Outcome measures

Primary outcomes

  • IV infusion of nesiritide at a 3pmol/kg rate [48 hours]: Average changes in glucose disposal rates (GDR) and endogenous glucose production (EGP) from baseline corrected for body weight at steady state of the clamp during the high- and low-dose portions.
