Pharmacokinetics (PK) Study of Epinephrine Inhalation Aerosol in Healthy Volunteers

2014-08-27 03:12:56 | BioPortfolio


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.

Epinephrine auto-injector needle lengths can both subcutaneous and periosteal/intraosseous injection be avoided?

Administration of epinephrine should be intramuscularly in the anterolateral aspect of the thigh. The length of the epinephrine autoinjector, EAI, needle should assure intramuscular injection.

Medical and Biotech [MESH] Definitions

A racemic mixture of d-epinephrine and l-epinephrine.

Product of epinephrine O-methylation. It is a commonly occurring, pharmacologically and physiologically inactive metabolite of epinephrine.

A long-acting beta-2-adrenergic receptor agonist. It is a potent bronchodilator that may be administered orally or by aerosol inhalation.

Devices that cause a liquid or solid to be converted into an aerosol (spray) or a vapor. It is used in drug administration by inhalation, humidification of ambient air, and in certain analytical instruments.

A medical device used to ensure the proper amount of medication is delivered for inhalation. Usually, it is a small aerosol canister placed in a plastic holder. When the canister is pressed, a calibrated amount of drug is released.
