  • Baseline Concentration (C0) of Labeled Epinephrine Total Epinephrine [ Time Frame: 0 to 30 minutes prior to dosing ]
    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.
  • Area Under the Curve From Time Zero to 6 Hours Post-dose (AUC[0-6]) [ Time Frame: Pre-dose 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), 5, 15, 30, 45, 60, 90, 120, 180, 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.
  • Peak Concentration (Cmax) for Total Epinephrine From Time Zero to 6 Hours Post-dose [ Time Frame: Pre-dose 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), 5, 15, 30, 45, 60, 90, 120, 180, 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.
  • Time to Reach Peak Concentration (Tmax) for Total Epinephrine [ Time Frame: Pre-dose 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), 5, 15, 30, 45, 60, 90, 120, 180, 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.
  • Half-life (t1/2) for Total Epinephrine [ Time Frame: Pre-dose 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), 5, 15, 30, 45, 60, 90, 120, 180, 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 decrease to half the peak concentration in plasma during the treatment period.
  • Concentration vs. Time for Total Epinephrine From Time Zero to 6 Hours Post-dose [ Time Frame: Pre-dose 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), 5, 15, 30, 45, 60, 90, 120, 180, 240, and 360 minutes post-dose in each treatment period and were analyzed using an established analysis method.
Pharmacokinetics [ Time Frame: 5, 15, 30, 45, 60 90, 120, 180, 240 and 360 min postdose ]
PK blood samples will be taken from a vein in a hand or arm via indwelling anticoagulated IV catheters, or by venipunctures, at scheduled time points

Pharmacokinetics (PK) Study of Epinephrine Inhalation Aerosol in Healthy Volunteers
Phase I/II Study Epinephrine Inhalation Aerosol USP, an HFA-MDI Clinical Study-B for Assessment of Pharmacokinetics
This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), in healthy male and female adult volunteers. Safety of E004 will also be evaluated, under augmented dose conditions.

This study is a randomized, evaluator-blind, single dose, three-arm, crossover, PK study, to be conducted in ~18 healthy, male and female, adult volunteers. PK will be studied at two dose strengths (Arm T1 and Arm T2). A currently marketed, non-labeled, Epinephrine CFC-MDI will be used as a Reference Control (Arm C).

  • At the Screening Visit and the beginning of each Study Visit, each subject will be trained on the correct self-administration of MDI. The following three randomized treatments will be self-administered, at three Study Visits:

    • Treatment T1: Ten (10) inhalations of the low dose E004(125 mcg/inhalation), totaling 1.25 mg of epinephrine;
    • Treatment T2: Ten (10) inhalations of the high dose E004 (160 mcg/inhalation), totaling 1.60 mg of epinephrine;
    • Treatment C: Ten (10) inhalations of Epinephrine CFC-MDI (220 mcg/inhalation, totaling 2.2 mg of epinephrine base equivalent).
  • PK blood samples will be taken from a vein at scheduled time points.
  • Safety parameters and adverse drug events, if any, will be monitored and documented at each study visit. An End-of-Study (EOS) safety evaluation will be conducted.
