E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to assess EGP after dosing with TI Inhalation Powder and compare it to EGP after sc administration of insulin lispro or inhalation of Exubera insulin during a meal challenge with 12 fluid ounces of Boost plus®. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this trial are to: • Assess EGP after dosing with TI Inhalation Powder in comparison to EGP after sc administration of Insulin Lispro and inhalation of Exubera insulin during a euglycemic glucose clamp procedure. • Characterize the pharmacokinetic and pharmacodynamic properties of TI Inhalation Powder, Insulin Lispro or Exubera insulin. • Assess the effect of TI Inhalation Powder, Insulin Lispro or Exubera insulin on endogenous insulin secretion. • Assess the effect of the 3 treatments on C-peptide, glucagon and free fatty acids (FFA) concentrations. |
