Design outcomes

Primary

MeasureTime frame
Main Objective: To compare the pharmacokinetic response (based on the time to maximum observed serum insulin concentration) of rapid acting insulin aspart after sub-cutaneous injection of a defined dose (volume) at 1 versus 9 injection sites in patients with type 1 diabetes.;Secondary Objective: To characterize and compare the pharmacokinetic and pharmacodynamic profiles of rapid acting insulin aspart after sub-cutaneous injection of a defined dose (volume) at 1 versus 9 injection sites in patients with T1DM. To assess the safety and tolerability of rapid acting insulin aspart after subcutaneous injection of a defined dose (volume) at 1 versus 9 injection sites in patients with T1DM. ;Primary end point(s): Primary Pharmacokinetic Endpoint: tmax(ins), time to maximum observed serum insulin aspart concentration;Timepoint(s) of evaluation of this end point: During Clamp Experiment

Secondary
