Summary

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.

Clinical Details

Official title: Phase I/II Study Epinephrine Inhalation Aerosol USP, an HFA-MDI Clinical Study-B for Assessment of Pharmacokinetics

General Health Assessment

Laboratory Analysis

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.
