E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To compare the pharmacodynamic response of single oral doses of PSN821 following a MMTT (based on the area under the glucose concentration-time curve from 1-6 hours post-dose, i.e. from 0-5 hours after a MMTT) • To establish the dose response relationship for the glucose lowering effect of PSN821 using reactive glucose area under the curve (AUC) |
|
E.2.2 | Secondary objectives of the trial |
• To compare other pharmacodynamic properties (based on glucose, insulin and C-peptide measurements) of single oral doses of PSN821 before and following a MMTT • To compare the pharmacokinetic (PK) exposure and properties of each single oral dose for 12h post-dosing • To assess the PK/PD relationship (based on AUC PSN821 and AUC glucose) • To assess the short-term safety after single oral dosing |
