Detailed Description:

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.

Ages Eligible for Study:   18 Years to 30 Years
