NCT01188577

Brief Summary

This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), using a stable isotope deuterium-labeled epinephrine (epinephrine-d3) to differentiate the administered drug from the endogenous epinephrine, in healthy male and female adult volunteers. The current study is designed for a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be evaluated, under augmented dose conditions.

Outcome Measures

Primary Outcomes (6)

  • Baseline Concentration (C0) of Total Epinephrine

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at Baseline (prior to dosing) in each treatment period following a specified washout period (3-14 days), and were analyzed using an established analysis method. Baseline concentration (C0) is the concentration of epinephrine measured in the plasma at this time point.

    0 to 30 minutes prior to dosing

  • Peak Concentration (Cmax) of Total Epinephrine From Time Zero to 6 Hours Post-dose

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at 0 (baseline), 2, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 45, 60, 90, 120, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method. Peak (maximum) concentration (Cmax) is the highest concentration of epinephrine measured in plasma during the treatment period.

    Pre-dose to 6 hours post-dose

  • Area Under the Curve From Time Zero to 6 Hours Post-dose (AUC[0-6]) for Total Epinephrine

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at 0 (baseline), 2, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 45, 60, 90, 120, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method. Area under the curve from time zero to 6 hours post-dose (AUC\[0-6\]) was calculated using the trapezoidal rule.

    Pre-dose to 6 hours post-dose

  • Time to Reach Peak Concentration (Tmax) for Total Epinephrine

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at 0 (baseline), 2, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 45, 60, 90, 120, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method. Tmax is the amount of time it takes for epinephrine to reach peak concentration in plasma during the treatment period.

    Pre-dose to 6 hours post-dose

  • Half-life (t1/2) of Total Epinephrine

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at 0 (baseline), 2, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 45, 60, 90, 120, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method. Half-life (t1/2) is the amount of time it takes for epinephrine to decrease to half the peak concentration in plasma during the treatment period.

    Pre-dose to 6 hours post-dose

  • Concentration vs. Time for Total Epinephrine From Time Zero to 6 Hours Post-dose

    Patient PK blood samples were taken from a vein in a hand or arm via indwelling heparin-anticoagulated IV catheters, or by venipunctures at 0 (baseline), 2, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 45, 60, 90, 120, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method.

    Pre-dose to 6 hours post-dose
